技术领域technical field
本发明涉及通信技术领域，特别涉及一种调度许可信息下发、确定、更新方法、系统和设备。The present invention relates to the field of communication technology, in particular to a method, system and device for issuing, determining and updating scheduling permission information.
背景技术Background technique
在UL-MIMO（UpLink Multiple Input Multiple Output，上行多输入多输出）通信系统中，UE（User Equipment，用户设备）与基站之间传输的数据流可以为双数据流（简称为双流）或单数据流（简称为单流）。双流是指基站每次调度两个不同的数据块，其中一个是主数据块，一个是辅数据块，主数据块对应的数据流称为主流，主流承载在E-DPDCH（E-DCHDedicated Physical Data Channel，E-DCH专用物理数据信道）上，辅数据块对应的数据流称为辅流，辅流承载在S-E-DPDCH（Secondary E-DCH Dedicated Physical Data Channel，辅E-DCH专用物理数据信道）上。单流是指基站每次调度一个数据块。在数据块的传输调度过程中，基站需要对E-DPDCH和S-E-DPDCH的发射功率进行控制，以降低UE对服务小区和其它相邻小区造成的上行干扰，上行干扰的程度可以使用ROT（Rise over Thermal，上行干扰抬升）来表征。In the UL-MIMO (UpLink Multiple Input Multiple Output, uplink multiple input multiple output) communication system, the data stream transmitted between UE (User Equipment, user equipment) and the base station can be dual data stream (referred to as dual stream) or single data stream stream (referred to as single stream). Dual stream means that the base station schedules two different data blocks each time, one of which is the main data block and the other is the auxiliary data block. Channel, E-DCH Dedicated Physical Data Channel), the data stream corresponding to the secondary data block is called the secondary stream, and the secondary stream is carried on the S-E-DPDCH (Secondary E-DCH Dedicated Physical Data Channel, secondary E-DCH dedicated physical data channel) superior. Single stream means that the base station schedules one data block each time. During the transmission scheduling process of data blocks, the base station needs to control the transmission power of E-DPDCH and S-E-DPDCH to reduce the uplink interference caused by the UE to the serving cell and other adjacent cells. The degree of uplink interference can be determined using ROT (Rise over Thermal, uplink interference rise) to characterize.
在双流传输时，一种传输调度过程可以如下：第一，基站通过内环功率控制和外环功率控制相结合的方式保证DPCCH（Dedicated Physical Control Channel，专用物理控制信道）在接收端（即基站侧）接收信噪比的稳定性；第二，基站设置E-DPDCH相对于DPCCH的发射功率偏置，该发射功率偏置的索引值在基站侧被称为SG（Scheduled Grant，调度许可信息），然后基站将该SG下发给UE；第三，UE根据该SG确定E-DPDCH上的发射功率，同时对S-E-DPDCH采用与E-DPDCH相同的发射功率；第四，UE根据确定后的E-DPDCH和S-E-DPDCH上的发射功率进行E-TFCI（E-DCH Transport Format Combination Indicator，E-DCH传输格式组合指示）的选择，进而根据E-TFCI确定出合适的数据块大小和传输格式。During dual-stream transmission, a transmission scheduling process can be as follows: First, the base station ensures that the DPCCH (Dedicated Physical Control Channel, Dedicated Physical Control Channel) at the receiving end (that is, the base station side) the stability of the received signal-to-noise ratio; second, the base station sets the transmission power offset of E-DPDCH relative to DPCCH, and the index value of the transmission power offset is called SG (Scheduled Grant, scheduling permission information) on the base station side , and then the base station sends the SG to the UE; thirdly, the UE determines the transmit power on the E-DPDCH according to the SG, and at the same time uses the same transmit power for the S-E-DPDCH as the E-DPDCH; fourthly, the UE E-TFCI (E-DCH Transport Format Combination Indicator, E-DCH transport format combination indication) is selected based on the transmission power on E-DPDCH and S-E-DPDCH, and then the appropriate data block size and transmission format are determined according to E-TFCI .
显然，第二步骤和第三步骤中所展示的SG确定方法是较为重要的环节。但是在实际情况中，鉴于承载辅流的S-E-DPDCH相对要比承载主流的E-DPDCH的信道质量要差，当EDPDCH和S-E-DPDCH同时采用相同的发射功率对E-TFCI进行选择时，并不能够实现良好的上行干扰控制。Obviously, the SG determination method shown in the second step and the third step is a relatively important link. However, in practice, since the channel quality of the S-E-DPDCH carrying the auxiliary stream is relatively worse than that of the E-DPDCH carrying the mainstream stream, when the EDPDCH and S-E-DPDCH use the same transmit power to select the E-TFCI at the same time, and Good uplink interference control cannot be achieved.

为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施方式作进一步地详细描述。In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
实施例一Embodiment one
请参考图1，其示出了本发明实施例一提供的调度许可信息确定方法的方法流程图。该调度许可信息确定方法可以包括：Please refer to FIG. 1 , which shows a flowchart of a method for determining scheduling permission information provided by Embodiment 1 of the present invention. The method for determining scheduling permission information may include:
步骤101，基站获取当前信道参数，当前信道参数包括信道质量差异SR；Step 101, the base station obtains the current channel parameters, the current channel parameters include the channel quality difference SR;
基站在对用户设备进行传输调度时，可以首先获取当前信道参数，当前信道参数可以包括有信道质量差异SR、MIMO信道条件、ROT水平、UE信息等信息。根据不同的实施例，当前信道参数的具体参数内容可以略有不同。When the base station performs transmission scheduling for the user equipment, it may first obtain the current channel parameters, which may include information such as channel quality difference SR, MIMO channel conditions, ROT level, and UE information. According to different embodiments, the specific parameter content of the current channel parameter may be slightly different.
步骤102，基站根据当前信道参数确定传输指示信息和参考调度许可信息SGtotal；Step 102, the base station determines transmission indication information and reference scheduling permission information SGtotal according to current channel parameters;
基站首先可以根据当前信道参数确定传输指示信息，传输指示信息用于表征单流传输模式或双流传输模式，是基站对用户设备需要采用的传输模式的指示，通常采用秩信息Rank=1或2来表示。基站根据当前信道参数确定传输指示信息的过程可以参考现有技术。The base station can first determine the transmission indication information according to the current channel parameters. The transmission indication information is used to represent the single-stream transmission mode or the dual-stream transmission mode. express. For the process of the base station determining the transmission instruction information according to the current channel parameters, reference may be made to the prior art.
参考调度许可信息SGtotal则表征由基站根据当前信道参数计算获得的一个功率比。具体地讲，SGtotal是承载数据的信道（E-DPDCH和S-E-DPDCH）的期望接收功率之和相对于导频（pilot）信道DPCCH的参考接收功率PD的比值。The reference scheduling grant information SGtotal represents a power ratio calculated and obtained by the base station according to the current channel parameters. Specifically, SGtotal is the ratio of the sum of expected received powers of data-carrying channels (E-DPDCH and SE-DPDCH) to the reference received powerPD of the pilot channel (pilot) DPCCH.
在基站根据当前信道参数确定传输指示信息为单流传输模式时，基站可以根据单流调度许可信息SGsingle确定参考调度许可信息SGtotal。此处基本与现有技术相同，也即令参考调度许可信息SGtotal=单流调度许可信息SGsingle。单流调度许可信息SGsingle可以由基站根据当前信道参数来计算得到。When the base station determines that the transmission indication information is a single-stream transmission mode according to the current channel parameters, the base station may determine the reference scheduling grant information SGtotal according to the single-stream scheduling grant information SGsingle . Here, it is basically the same as the prior art, that is, the reference scheduling permission information SGtotal =single-flow scheduling permission information SGsingle . The single-stream scheduling grant information SGsingle can be calculated by the base station according to the current channel parameters.
在基站根据当前信道参数确定传输指示信息为双流传输模式时，可以根据主流调度许可信息SGprimary和辅流调度许可信息SGsecondary确定参考调度许可信息SGtotal。具体地讲，为了能够对上行干扰进行控制，基站需要根据主流调度许可信息SGprimary和辅流调度许可信息SGsecondary两者来确定参考调度许可信息SGtotal。其中，SGsecondary可以等于SGprimary*SR，SR表征S-E-DPDCH相对于E-DPDCH的信道质量差异。参考调度许可信息SGtotal可以等于主流调度许可信息SGprimary和辅流调度许可信息SGsecondary两者之和。主流调度许可信息SGprimary也可以由基站根据当前信道参数来计算得到。在不同的实施例中，SGsecondary与SGprimary的关系可以采用其它方式表示，但是在实际含义相同时，均应当认为是本文的保护内容。When the base station determines that the transmission indication information is a dual-stream transmission mode according to the current channel parameters, the reference scheduling grant information SGtotal may be determined according to the primary stream scheduling grant information SGprimary and the secondary stream scheduling grant information SGsecondary . Specifically, in order to be able to control the uplink interference, the base station needs to determine the reference scheduling grant information SGtotal according to both the primary scheduling grant information SGprimary and the secondary scheduling grant information SGsecondary . Wherein, SGsecondary may be equal to SGprimary *SR, and SR represents the channel quality difference between SE-DPDCH and E-DPDCH. The reference scheduling permission information SGtotal may be equal to the sum of the primary scheduling permission information SGprimary and the secondary streaming scheduling permission information SGsecondary . The mainstream scheduling grant information SGprimary can also be calculated by the base station according to the current channel parameters. In different embodiments, the relationship between the SGsecondary and the SGprimary may be expressed in other ways, but when the actual meanings are the same, they should be regarded as the protection content of this document.
步骤103，基站下发参考调度许可信息SGtotal、信道质量差异SR和传输指示信息给用户设备；Step 103, the base station sends reference scheduling grant information SGtotal , channel quality difference SR and transmission instruction information to the user equipment;
基站可以通过指定TTI（Transmission Time Interval，传输时间间隔）来将参考调度许可信息SGtotal、信道质量差异SR和传输指示信息中的全部或者部分同时下发给用户设备。The base station may deliver all or part of the reference scheduling grant information SGtotal , the channel quality difference SR and the transmission instruction information to the user equipment simultaneously by specifying a TTI (Transmission Time Interval, transmission time interval).
步骤104，用户设备接收由基站下发的参考调度许可信息SGtotal、信道质量差异SR和传输指示信息；Step 104, the user equipment receives the reference scheduling grant information SGtotal , channel quality difference SR and transmission indication information sent by the base station;
用户设备可以接收指定TTI中由基站下发的参考调度许可信息SGtotal、信道质量差异SR和传输指示信息中的全部或者部分。The user equipment may receive all or part of the reference scheduling grant information SGtotal , the channel quality difference SR and the transmission instruction information issued by the base station in a specified TTI.
步骤105，用户设备根据参考调度许可信息SGtotal、信道质量差异SR和传输指示信息确定单流传输时的单流调度许可信息SGsingle或双流传输时的主流调度许可信息SGprimary和辅流调度许可信息SGsecondary。Step 105, the user equipment determines the single-stream scheduling grant information SGsingle during single-stream transmission or the primary scheduling grant information SGprimary and auxiliary stream scheduling grant during dual-stream transmission according to the reference scheduling grant information SGtotal , channel quality difference SR, and transmission indication information Information SGsecondary .
当传输指示信息表征单流传输模式时，用户设备可以根据参考调度许可信息SGtotal确定单流传输时的单流调度许可信息SGsingle。When the transmission indication information represents a single-stream transmission mode, the user equipment may determine single-stream scheduling grant information SGsingle during single-stream transmission according to the reference scheduling grant information SGtotal .
当传输指示信息表征双流传输模式时，用户设备根据SGtotal和SR可以确定主流调度许可信息SGprimary和辅流调度许可信息SGsecondary。具体地讲，用户设备可以根据参考调度许可信息SGtotal和信道质量差异SR确定主流调度许可信息SGprimary为：SG·primary的量化值，SG·primary=SGtotal/(1+SR)；When the transmission indication information represents a dual-stream transmission mode, the user equipment can determine the primary stream scheduling grant information SGprimary and the secondary stream scheduling grant information SGsecondary according to SGtotal and SR. Specifically, the user equipment can determine the mainstream scheduling grant information SGprimary according to the reference scheduling grant information SGtotal and the channel quality difference SR as:the quantized value of SGprimary, SGprimary =SGtotal /(1+SR);
用户设备还可以根据参考调度许可信息SGtotal和信道质量差异SR确定辅流调度许可信息SGsecondary为：SG·secondary的量化值，SG·secondary=SGtotal-SGprimary，或SG·secondary=SGprimary*SR。The user equipment can also determine the secondary stream scheduling permission information SGsecondary according to the reference scheduling permission information SGtotal and the channel quality difference SR as:the quantized value of SGsecondary, SGsecondary =SGtotal -SGprimary, or SGsecondary =SGprimary *SR.
用户设备可以根据SGprimary来指导双流的发射功率的确定过程和主流的E-TFC选择过程，同时用户设备仅使用SGsecondary指导辅流的E-TFC选择过程，最后根据各自选择的E-TFC可以确定主流和辅流分别传输的TBS（Transport Block Size，传输块大小），从而可以按照该TBS进行UL-MIMO的数据传输。The user equipment can guide the process of determining the transmission power of the dual stream and the selection process of the mainstream E-TFC according to the SGprimary , while the user equipment only uses the SGsecondary to guide the E-TFC selection process of the auxiliary stream, and finally according to the E-TFC selected by each user can Determine the TBS (Transport Block Size, transport block size) for the main stream and the auxiliary stream to be transmitted respectively, so that UL-MIMO data transmission can be performed according to the TBS.
综上所述，本实施例一提供的调度许可信息确定方法，通过基站向用户设备下发参考调度许可信息SGtotal和信道质量差异SR，可以使用户设备能够确定主流调度许可信息SGprimary和辅流调度许可信息SGsecondary，其中主流调度许可信息SGprimary用于指导双流的发射功率的确定过程和主流的E-TFC选择过程，而辅流调度许可信息SGsecondary则只用于指导辅流的E-TFC选择过程，从而达到了辅流的E-TFC选择更为准确的效果，进而达到了基站可以有效控制上行干扰的效果。To sum up, the scheduling grant information determination method provided in the first embodiment can enable the user equipment to determine the mainstream scheduling grant information SGprimary andsecondary Stream scheduling permission information SGsecondary , in which the mainstream scheduling permission information SGprimary is used to guide the process of determining the transmission power of the dual stream and the process of selecting the E-TFC of the mainstream, while the secondary stream scheduling permission information SGsecondary is only used to guide the E-TFC of the secondary stream. -TFC selection process, so as to achieve the effect of more accurate E-TFC selection of the auxiliary stream, and then achieve the effect that the base station can effectively control the uplink interference.
实施例二Embodiment two
请参考图2，其示出了本发明实施例二提供的调度许可信息下发方法的方法流程图。为了进行更为详尽地描述，本实施例中以基站一侧来进行描述，该调度许可信息下发方法可以包括：Please refer to FIG. 2 , which shows a flow chart of the method for issuing scheduling permission information provided by Embodiment 2 of the present invention. For a more detailed description, the base station side is used for description in this embodiment, and the method for issuing scheduling permission information may include:
步骤201，基站获取当前信道参数，当前信道参数包括信道质量差异SR；Step 201, the base station obtains the current channel parameters, the current channel parameters include the channel quality difference SR;
基站在对用户设备进行传输调度时，可以首先获取当前信道参数，当前信道参数可以包括有信道质量差异SR、MIMO信道条件、ROT水平、UE信息等信息。根据不同的实施例，当前信道参数的具体参数内容可以略有不同。When the base station performs transmission scheduling for the user equipment, it may first obtain the current channel parameters, which may include information such as channel quality difference SR, MIMO channel conditions, ROT level, and UE information. According to different embodiments, the specific parameter content of the current channel parameter may be slightly different.
步骤202，基站根据当前信道参数确定传输指示信息和参考调度许可信息SGtotal；；Step 202, the base station determines transmission instruction information and reference scheduling permission information SGtotal according to the current channel parameters;
本实施例中，主要以基站需要对UE进行双流调度来描述，单流调度的情况可以参考现有技术。当基站需要对UE进行双流调度（也即传输指示信息表征双流传输模式）时，为了能够对上行干扰进行控制，基站需要根据预定方式来确定参考调度许可信息SGtotal。具体地讲，基站可以采用主流调度许可信息SGprimary和辅流调度许可信息SGsecondary两者之和来确定参考调度许可信息SGtotal，其中，SGsecondary可以等于SGprimary*SR，SR表征S-E-DPDCH相对于E-DPDCH的信道质量差异。信道质量差异SR通常为：In this embodiment, it is mainly described that the base station needs to perform dual-stream scheduling on the UE, and for single-stream scheduling, reference may be made to the prior art. When the base station needs to perform dual-stream scheduling on the UE (that is, the transmission instruction information represents a dual-stream transmission mode), in order to control uplink interference, the base station needs to determine reference scheduling grant information SGtotal according to a predetermined method. Specifically, the base station can use the sum of the mainstream scheduling permission information SGprimary and the secondary scheduling permission information SGsecondary to determine the reference scheduling permission information SGtotal , where SGsecondary can be equal to SGprimary * SR, and SR represents SE-DPDCH Channel quality difference relative to E-DPDCH. The channel quality difference SR is usually:
其中，SINRS-E-DPDCH为S-E-DPDCH的接收信干噪比，SINRE-DPDCH为E-DPDCH的接收信干噪比。可以由基站直接计算获得。但是根据不同的应用场景，基站确定参考调度许可信息SGtotal的过程中采用的预定方式可以略有不同：Wherein, SINRSE-DPDCH is the received SINR of SE-DPDCH, and SINRE-DPDCH is the received SINR of E-DPDCH. It can be directly calculated by the base station. However, according to different application scenarios, the reservation method adopted by the base station in the process of determining the reference scheduling permission information SGtotal may be slightly different:
通常场景下，基站可以直接确定参考调度许可信息SGtotal等于主流调度许可信息SGprimary和辅流调度许可信息SGsecondary两者之和。In a common scenario, the base station may directly determine that the reference scheduling permission information SGtotal is equal to the sum of the primary scheduling permission information SGprimary and the secondary scheduling permission information SGsecondary .
另一种场景下，基站可以直接确定参考调度许可信息SGtotal等于：SGprimary(1+SR)；In another scenario, the base station can directly determine that the reference scheduling permission information SGtotal is equal to: SGprimary (1+SR);
再一种场景下，基站可以直接确定参考调度许可信息SGtotal等于：E-DPDCH和S-E-DPDCH相对于DPCCH的总的允许的接收功率比值SG·total的量化值。In another scenario, the base station may directly determine that the reference scheduling grant information SGtotal is equal to: the quantized value of the total allowable received power ratio SG·total of E-DPDCH and SE-DPDCH relative to DPCCH.
上述三种场景可以认为是等同实现方案，以最后一种场景为例，基站确定参考调度许可信息SGtotal的详细过程可以是：The above three scenarios can be considered as equivalent implementation solutions. Taking the last scenario as an example, the detailed process for the base station to determine the reference scheduling permission information SGtotal can be as follows:
第一，基站根据当前信道参数确定参考接收总功率Ptotal和DPCCH的参考接收功率PD，其中，当前信道参数至少包括：上行干扰抬升；First, the base station determines the total reference received power Ptotal and the reference received powerPD of the DPCCH according to the current channel parameters, where the current channel parameters at least include: uplink interference rise;
为了实现功率控制，基站首先可以根据当前信道参数确定参考接收总功率Ptotal和DPCCH的参考接收功率PD。其中，当前信道参数通常包括有MIMO信道条件、ROT水平、UE信息等信息。此步骤为现有技术。In order to implement power control, the base station may first determine the total reference received power Ptotal and the reference received powerPD of the DPCCH according to the current channel parameters. Wherein, the current channel parameters usually include MIMO channel conditions, ROT level, UE information and other information. This step is prior art.
第二，基站根据参考接收总功率Ptotal和DPCCH的参考接收功率PD，计算得到E-DPDCH和S-E-DPDCH的期望接收功率之和相对于DPCCH的参考接收功率PD的比值SG·total为：SG·total=(Ptotal-PD-Px)/PD；Second, the base station calculates the ratio SGtotalof the sum of the expected received power of E-DPDCH and SE-DPDCH to the reference received powerPD of DPCCH according to the total reference received power Ptotal and the reference received powerPD of DPCCH as: SGtotal = (Ptotal -PD -Px )/PD ;
假设没有其它信道功率的干扰，只包括DPCCH、E-DPDCH和S-E-DPDCH三个信道的接收功率，那么基站侧能够计算得到E-DPDCH和S-E-DPDCH的期望接收功率之和的可能最大值为：PE-DPDCH，receive+PS-E-DPDCH，receive=Ptotal-PD，而实际上，通常还包括有诸如S-DPCCH、E-DPCCH、S-E-DPCCH和HS-DPCCH之类的其它信道，这些其它信道的接收功率在本文中统一利用Px来表征，所以基站可以计算得到E-DPDCH和S-E-DPDCH的期望接收功率之和相对于DPCCH的参考接收功率PD的比值SG·total为：SG·total=(Ptotal-PD-Px)/PD。Assuming that there is no interference from other channel power and only includes the received power of the three channels DPCCH, E-DPDCH and SE-DPDCH, then the base station side can calculate the possible maximum sum of the expected received power of E-DPDCH and SE-DPDCH as : PE-DPDCH, receive +PSE-DPDCH, receive =Ptotal -PD , but in fact, other channels such as S-DPCCH, E-DPCCH, SE-DPCCH and HS-DPCCH are usually included , the received power of these other channels is uniformly characterized by Px in this paper, so the base station can calculate the ratio SGtotalof the sum of the expected received power of E-DPDCH and SE-DPDCH relative to the reference received powerPD of DPCCH as: SGtotal =( Ptotal -PD -Px )/PD .
第三．基站确定参考调度许可信息SGtotal为：SG·total的量化值。third. The base station determines that the reference scheduling grant information SGtotal is: a quantized value of SG·total .

其中，参考调度许可信息SGtotal的相关信息可以为：参考调度许可信息SGtotal对应的索引值的绝对值，或与上次指定TTI下发的参考调度许可信息SGtotal的索引值的相对值。SG的索引值可以通过查询SG映射表获得，SG映射表是SG值和索引值一一对应的表，根据SG映射表可以查找与SG对应的索引值，也可以查找与索引值对应的SG，该表中的SG值均认为是量化后的SG值，不在该表中的SG值，可以认为是非量化的SG值。SG映射表可以采用现有技术中提供的SG映射表。Wherein, the relevant information of the reference scheduling grant information SGtotal may be: the absolute value of the index value corresponding to the reference scheduling grant information SGtotal , or the relative value to the index value of the reference scheduling grant information SGtotal delivered by the last specified TTI. The index value of SG can be obtained by querying the SG mapping table. The SG mapping table is a one-to-one correspondence between the SG value and the index value. According to the SG mapping table, the index value corresponding to the SG can be found, and the SG corresponding to the index value can also be searched.

实施例三Embodiment Three
请参考图3，其示出了本发明实施例三提供的调度许可信息确定方法的方法流程图。为了进行更为详尽地描述，对应于实施例三，本实施例中以用户设备一侧来进行描述，该调度许可信息确定方法可以包括：Please refer to FIG. 3 , which shows a flowchart of a method for determining scheduling permission information provided by Embodiment 3 of the present invention. For a more detailed description, corresponding to Embodiment 3, in this embodiment, the user equipment side is used for description, and the method for determining scheduling permission information may include:
步骤301，接收指定TTI中同时下发的参考调度许可信息SGtotal的相关信息、信道质量差异SR的相关信息和传输指示信息的相关信息中的全部或部分；Step 301, receiving all or part of the related information of the reference scheduling grant information SGtotal , the related information of the channel quality difference SR and the related information of the transmission instruction information issued simultaneously in the specified TTI;
UE中通常设置有用于保存基站下发信息的存储器，比如，UE可以通过存储器保存基站下发的参考调度许可信息SGtotal的相关信息、信道质量差异SR的相关信息和传输指示信息的相关信息。The UE is usually provided with a memory for storing information issued by the base station. For example, the UE can store information related to the reference scheduling grant information SGtotal , channel quality difference SR, and transmission indication information delivered by the base station through the memory.
UE可以在指定TTI中接收基站下发的信息，根据步骤204可知，基站下发的方式可能有多种，对应地，UE的接收方式也有多种。具体地讲：The UE can receive the information delivered by the base station in a specified TTI. According to step 204, there may be multiple ways for the base station to deliver the information. Correspondingly, there are also many ways for the UE to receive the information. Specifically:
用户设备接收指定TTI中同时下发的参考调度许可信息SGtotal的相关信息、信道质量差异SR的相关信息和传输指示信息的相关信息；The user equipment receives related information about the reference scheduling grant information SGtotal , related information about the channel quality difference SR, and related information about the transmission instruction information delivered simultaneously in the specified TTI;
或，用户设备接收指定TTI中同时下发的参考调度许可信息SGtotal的相关信息和信道质量差异SR的相关信息；Or, the user equipment receives the related information of the reference scheduling grant information SGtotal and the related information of the channel quality difference SR delivered simultaneously in the specified TTI;
或，用户设备接收指定TTI中同时下发的参考调度许可信息SGtotal的相关信息和传输指示信息的相关信息；Or, the user equipment receives the related information of the reference scheduling grant information SGtotal and the related information of the transmission instruction information sent simultaneously in the specified TTI;
或，用户设备接收指定TTI中同时下发的信道质量差异SR的相关信息和传输指示信息的相关信息；Or, the user equipment receives the information about the channel quality difference SR and the information about the transmission instruction information delivered simultaneously in the specified TTI;
或，用户设备接收指定TTI中下发的参考调度许可信息SGtotal的相关信息；Or, the user equipment receives relevant information of the reference scheduling grant information SGtotal delivered in the specified TTI;
或，用户设备接收指定TTI中下发的信道质量差异SR的相关信息；Or, the user equipment receives information about the channel quality difference SR issued in a specified TTI;
或，用户设备接收指定TTI中下发的传输指示信息的相关信息。Or, the user equipment receives information related to the transmission indication information issued in a specified TTI.
步骤302，根据接收到的参考调度许可信息SGtotal的相关信息、信道质量差异SR的相关信息和/或传输指示信息更新上次保存的参考调度许可信息SGtotal、信道质量差异SR和/或传输指示信息；Step 302: Update the last saved reference scheduling grant information SGtotal , channel quality difference SR and/or transmission indication information according to the received reference scheduling grant information SGtotal , channel quality difference SR related information and/or transmission instruction information. instructions;
用户设备可以当前接收到的信息更新上次保存的信息，比如，用户设备在指定TTI中同时接收到参考调度许可信息SGtotal的相关信息、信道质量差异SR的相关信息和传输指示信息时，可以同时对三个信息都进行更新；或者，用户设备只接收到参考调度许可信息SGtotal的相关信息时，可以只更新上次保存的参考调度许可信息SGtotal信息；再或者，用户设备接收到指定TTI中下发的信道质量差异SR的相关信息，而未收到参考调度许可信息SGtotal的相关信息时，可以维持上次保存的参考调度许可信息SGtotal不变，更新上次保存的信道质量差异SR。The user equipment can update the information saved last time with the currently received information. For example, when the user equipment receives the information related to the reference scheduling grant information SGtotal , the information related to the channel quality difference SR, and the transmission indication information at the same time in a specified TTI, it can Update all three pieces of information at the same time; or, when the user equipment only receives information related to the reference scheduling permission information SGtotal , it may only update the last saved reference scheduling permission information SGtotal information; or, the user equipment receives the specified When the relevant information of the channel quality difference SR issued in TTI is not received, but the relevant information of the reference scheduling grant information SGtotal is not received, the last saved reference scheduling grant information SGtotal can be kept unchanged, and the last saved channel quality can be updated Difference SR.
但是作为优选地方式，当用户设备接收到指定TTI中下发的信道质量差异SR的相关信息，而未收到参考调度许可信息SGtotal的相关信息时，也可以维持上次计算得到的SGprimary不变，更新上次保存的信道质量差异SR，并根据更新后的信道质量差异SR来更新上次保存的参考调度许可信息SGtotal=SGprimary（1+SR），以便后续使用。也就是说，维持上次计算得到的SGprimary不变，更新上次保存的信道质量差异SR，并根据更新后的信道质量差异SR来更新上次保存的参考调度许可信息SGtotal=上次计算得到的SGprimary（1+更新后的信道质量差异SR）。However, as a preferred manner, when the user equipment receives the relevant information of the channel quality difference SR delivered in the specified TTI, but does not receive the relevant information of the reference scheduling grant information SGtotal , it can also maintain the SGprimary calculated last time No change, the last saved channel quality difference SR is updated, and the last saved reference scheduling grant information SGtotal =SGprimary (1+SR) is updated according to the updated channel quality difference SR for subsequent use. That is to say, keep the SGprimary obtained from the last calculation unchanged, update the last saved channel quality difference SR, and update the last saved reference scheduling permission information SGtotal = last calculation according to the updated channel quality difference SR The obtained SGprimary (1+updated channel quality difference SR).
步骤303，根据参考调度许可信息SGtotal、信道质量差异SR和传输指示信息确定单流传输时的单流调度许可信息SGsingle或双流传输时的主流调度许可信息SGprimary和辅流调度许可信息SGsecondary；Step 303, according to the reference scheduling permission information SGtotal , the channel quality difference SR and the transmission instruction information, determine the single-stream scheduling permission information SGsingle during single-stream transmission or the mainstream scheduling permission information SGprimary and secondary stream scheduling permission information SG during dual-stream transmissionsecondary ;
假设UE初始使用双流传输模式，此时，可能存在三种场景：第一，基站指示UE继续采用双流传输模式，UE保持双流传输模式；第二，基站指示UE继续采用双流传输模式，但是UE根据实际情况自行选择采用单流传输模式，比如UE当前需要下发的数据量较小或者自身可用发射功率无法达到目标值等；第三，基站指示UE由双流切换到单流，UE采用单流传输模式。三种场景中UE对SG的确定过程分别描述如下：Assuming that the UE initially uses the dual-stream transmission mode, there may be three scenarios at this time: first, the base station instructs the UE to continue to use the dual-stream transmission mode, and the UE maintains the dual-stream transmission mode; second, the base station instructs the UE to continue to use the dual-stream transmission mode, but the UE according to The actual situation chooses to use the single-stream transmission mode, such as the amount of data that the UE currently needs to send is small or its own available transmission power cannot reach the target value; third, the base station instructs the UE to switch from dual-stream to single-stream, and the UE uses single-stream transmission model. The process of determining the SG by the UE in the three scenarios is described as follows:
第一，当传输指示信息表征双流传输模式时，UE根据参考调度许可信息SGtotal和信道质量差异SR确定主流调度许可信息SGprimary为：SG·primary的量化值，SG·primary=SGtotal/(1+SR)；First, when the transmission indication information represents the dual-stream transmission mode, the UE determines the mainstream scheduling grant information SGprimary according to the reference scheduling grant information SGtotal and the channel quality difference SR as:the quantized value of SGprimary, SGprimary =SGtotal /( 1+SR);
根据参考调度许可信息SGtotal和信道质量差异SR确定辅流调度许可信息SGsecondary为：SG·secondary的量化值，SG·secondary=SGtotal-SGprimary，或SG·secondary=SGprimary*SR。According to the reference scheduling permission information SGtotal and the channel quality difference SR, determine the secondary stream scheduling permission information SGsecondary as:the quantized value of SGsecondary, SGsecondary =SGtotal -SGprimary , or SGsecondary =SGprimary* SR.
第二，当传输指示信息表征双流传输模式，但满足预设条件时，UE根据参考调度许可信息SGtotal确定单流调度许可信息SGsingle为：SG·single的量化值，SG·single=SGtotal。预设条件可以为：用户设备中待发送的数据量小于由基站下发的调度许可信息对应的第一阈值；或者，用户设备的当前可用发送功率小于由基站下发的调度许可信息对应的第二阈值。Second, when the transmission indication information represents the dual-stream transmission mode, but meets the preset conditions, the UE determines the single-stream scheduling grant information SGsingle according to the reference scheduling grant information SGtotal: the quantized value of SGsingle, SGsingle = SGtotal . The preset condition may be: the amount of data to be sent in the user equipment is less than the first threshold corresponding to the scheduling permission information issued by the base station; or, the currently available transmission power of the user equipment is less than the first threshold corresponding to the scheduling permission information issued by the base station. Two thresholds.
第三，当传输指示信息表征单流传输模式时，UE根据参考调度许可信息SGtotal确定单流调度许可信息SGsingle为：SG·single的量化值，SG·single=SGtotal。Third, when the transmission indication information represents a single-stream transmission mode, the UE determines the single-stream scheduling grant information SGsingle according to the reference scheduling grant information SGtotal as: the quantized value of SG·single , SG·single = SGtotal .
在第一种场景下，本实施例还包括如下步骤：In the first scenario, this embodiment also includes the following steps:
步骤304，用户设备根据主流调度许可信息SGprimary确定主流的发射功率、辅流的发射功率和主流的E-TFC；Step 304, the user equipment determines the transmit power of the mainstream, the transmit power of the secondary stream, and the E-TFC of the mainstream according to the scheduling permission information SGprimary of the mainstream;
用户设备在确定SGprimary之后，可以根据SGprimary确定主流的发射功率PE-DPDCH，transmit为：SGprimary*PDPCCH，transmit，其中，PDPCCH，transmit为DPCCH的发射功率。After the user equipment determines the SGprimary , it can determine the mainstream transmission powerPE-DPDCH, transmit according to the SGprimary : SGprimary * PDPCCH, transmit , where PDPCCH, transmit is the transmission power of the DPCCH.
然后，用户设备可以确定辅流的发射功率PS-E-DPDCH，transmit为：PE-DPDCH，transmit，也即主流和辅流采用相同的发射功率；Then, the user equipment can determine the transmit power PSE-DPDCH, transmit of the secondary stream as: PE-DPDCH, transmit , that is, the primary stream and the secondary stream adopt the same transmit power;
然后，用户设备根据SGprimary选择主流的E-TFC，以便确定主流传输的TBS和传输格式，TBS和E-EFCI两者一一对应。TS25.321的附录B给出了E-TFCI和TBS的映射表，此处不做过多说明。Then, the user equipment selects the E-TFC of the mainstream according to the SGprimary , so as to determine the TBS and the transmission format of the mainstream transmission, and the TBS and the E-EFCI are in one-to-one correspondence. Appendix B of TS25.321 provides the mapping table between E-TFCI and TBS, and no further explanation is given here.
步骤305，用户设备根据辅流调度许可信息SGsecondary确定辅流的E-TFC。Step 305, the user equipment determines the E-TFC of the secondary stream according to the secondary stream scheduling permission information SGsecondary .
用户设备根据SGsecondary选择辅流的E-TFC，以便确定辅流传输的TBS和传输格式。The user equipment selects the E-TFC of the auxiliary stream according to the SGsecondary , so as to determine the TBS and transmission format of the auxiliary stream.
综上所述，本实施例三提供的调度许可信息确定方法，通过基站向用户设备下发参考调度许可信息SGtotal和信道质量差异SR，可以使用户设备能够确定主流调度许可信息SGprimary和辅流调度许可信息SGsecondary，其中主流调度许可信息SGprimary用于指导双流的发射功率的确定过程和主流的E-TFC选择过程，而辅流调度许可信息SGsecondary则只用于指导辅流的E-TFC选择过程，从而达到了辅流的E-TFC选择更为准确的效果，进而达到了基站可以有效控制上行干扰的效果。To sum up, the scheduling grant information determination method provided in the third embodiment can enable the user equipment to determine the mainstream scheduling grant information SGprimary andsecondary Stream scheduling permission information SGsecondary , in which the mainstream scheduling permission information SGprimary is used to guide the process of determining the transmission power of the dual stream and the process of selecting the E-TFC of the mainstream, while the secondary stream scheduling permission information SGsecondary is only used to guide the E-TFC of the secondary stream. -TFC selection process, so as to achieve the effect of more accurate E-TFC selection of the auxiliary stream, and then achieve the effect that the base station can effectively control the uplink interference.
需要补充说明的是，在本发明实施例中（包括上述三个实施例），SG·x的量化过程，具体地讲，可以采用如下步骤实现：It needs to be supplemented that, in the embodiments of the present invention (including the above three embodiments), the quantization process of SGx , specifically, can be implemented by the following steps:
在SG映射表中查找与SG·x匹配的SG，匹配的SG与SG·x的差值最小；Find the SG that matches SGx in the SG mapping table,and the difference between the matched SG and SGx is the smallest;
或，在SG映射表中查找大于SG·x的最小的SG；Or, look upthe smallest SG greater than SGx in the SG mapping table;
或，在SG映射表中查找小于SG·x的最大的SG；Or, look upthe largest SG smaller than SGx in the SG mapping table;
将查找到的SG作为SG·x的量化值，其中，x=total、single、primary或者secondary。Use the found SG as the quantized value of SG·x , where x=total, single, primary or secondary.
还需要补充说明的是，本发明实施例中对信道质量差异SR的具体形式不作限制，只要能反映辅流和主流的信道质量之间的差异即可。可选地，作为一个实施例，信道质量差异SR可以是S-E-DPDCH和E-DPDCH的发送功率相同的情况下，S-E-DPDCH和E-DPDCH的接收SINR（Signal to Interference plus Noise Ratio，信干噪比）的比值：It should be added that, in the embodiment of the present invention, there is no limitation on the specific form of the channel quality difference SR, as long as it can reflect the difference between the channel quality of the secondary stream and the mainstream stream. Optionally, as an embodiment, the channel quality difference SR may be the SINR (Signal to Interference plus Noise Ratio, Signal to Interference plus Noise Ratio, Signal to Interference plus Noise Ratio, Signal to Interference plus Noise Ratio, Noise Ratio) ratio:
本领域技术人员容易想到，信道质量差异SR也可以是其他形式，如信噪比的比值等。这些变化均落入本发明实施例的范围内。Those skilled in the art can easily imagine that the channel quality difference SR can also be in other forms, such as the ratio of the signal-to-noise ratio. These changes all fall within the scope of the embodiments of the present invention.

由于上述实施例均以基站下发参考调度许可信息SGtotal和信道质量差异SR来描述，但是本领域技术人员可以意识到基站可能下发的信息可以是其它组合。为此，请继续参考图11，其示出了本发明实施例七提供的调度许可信息更新方法的方法流程图。该调度许可信息更新方法用于用户设备中更新基站下发的信息。该调度许可信息更新方法可以包括：Since the above-mentioned embodiments are all described in terms of the base station sending the reference scheduling grant information SGtotal and the channel quality difference SR, those skilled in the art can realize that the information that the base station may send may be other combinations. For this reason, please continue to refer to FIG. 11 , which shows a flowchart of a method for updating scheduling permission information provided by Embodiment 7 of the present invention. The method for updating scheduling permission information is used in user equipment to update information issued by a base station. The method for updating scheduling permission information may include:
步骤1102，在指定TTI中接收由基站下发的调度许可信息SG和信道质量差异SR；Step 1102, receiving the scheduling grant information SG and channel quality difference SR issued by the base station in a specified TTI;
由于基站的不同下发方案，除了前述实施例中的方案之外，基站下发的调度许可信息SG还可以是：Due to the different distribution schemes of the base station, in addition to the schemes in the foregoing embodiments, the scheduling grant information SG issued by the base station can also be:
第一种方案，The first option,
单流调度时，向用户设备下发参考调度许可信息SGtotal=单流调度许可信息SGsingle。During single-flow scheduling, the reference scheduling permission information SGtotal =single-flow scheduling permission information SGsingle is issued to the user equipment.
双流调度时，向用户设备下发参考调度许可信息SGtotal=主流调度许可信息SGprimary。During dual-stream scheduling, the reference scheduling permission information SGtotal =mainstream scheduling permission information SGprimary is sent to the user equipment.
第二种方案：The second option:
单流调度时，向用户设备下发参考调度许可信息SGtotal=单流调度许可信息SGsingle。During single-flow scheduling, the reference scheduling permission information SGtotal =single-flow scheduling permission information SGsingle is issued to the user equipment.
双流调度时，向用户设备下发第二参考调度许可信息SGtotal·=2*主流调度许可信息SGprimary。During dual-stream scheduling, the second reference scheduling permission information SGtotal· =2*mainstream scheduling permission information SGprimary is delivered to the user equipment.
第三种方案：The third option:
单流调度时，向用户设备下发单流调度许可信息SGsingle。During single-stream scheduling, the single-stream scheduling permission information SGsingle is issued to the user equipment.
双流调度时，向用户设备下发主流调度许可信息SGprimary、辅流调度许可信息SGsecondary。During dual-stream scheduling, the primary stream scheduling permission information SGprimary and the secondary stream scheduling permission information SGsecondary are delivered to the user equipment.
对应地，用户设备可以接收基站下发的调度许可信息SG。Correspondingly, the user equipment may receive the scheduling grant information SG issued by the base station.
步骤1104，当接收到指定TTI中下发的信道质量差异SR，而未收到调度许可信息SG时，根据信道质量差异SR更新上次保存的调度许可信息SG。Step 1104, when receiving the channel quality difference SR delivered in the specified TTI but not receiving the scheduling grant information SG, update the last saved scheduling grant information SG according to the channel quality difference SR.
当接收到指定TTI中下发的信道质量差异SR，而未收到调度许可信息SG时，用户设备可以维持上次计算或者保存的SGprimary不变，根据更新后的信道质量差异SR来更新上次计算或者保存的参考调度许可信息为：SGtotal＝SGprimary（1+SR）。When receiving the channel quality difference SR delivered in the specified TTI but not receiving the scheduling grant information SG, the user equipment can keep the SGprimary calculated or saved last time unchanged, and update the upper channel quality difference SR according to the updated channel quality difference SR. The reference scheduling permission information calculated or saved for the second time is: SGtotal = SGprimary (1+SR).
或者，当接收到指定TTI中下发的信道质量差异SR，而未收到调度许可信息SG时，维持上次计算或者保存的SGprimary不变，根据更新后的信道质量差异SR来更新上次计算或者保存的辅流调度许可信息为：SGsecondary=SGprimary*SR。Or, when the channel quality difference SR issued in the specified TTI is received but the scheduling grant information SG is not received, the SGprimary calculated or saved last time remains unchanged, and the last time is updated according to the updated channel quality difference SR. The calculated or saved auxiliary stream scheduling permission information is: SGsecondary =SGprimary *SR.
综上所述，本实施例提供的调度许可信息更新方法，通过各个调度许可信息之间的换算关系，可以使用户设备能够在只接收到信道质量差异SR时，也可以对参考调度许可信息SGtotal或者辅流调度许可信息SGsecondary完成更新过程，从而达到了辅流的E-TFC选择更为准确的效果，进而达到了基站可以有效控制上行干扰的效果。To sum up, the method for updating scheduling grant information provided by this embodiment can enable the user equipment to update the reference scheduling grant information SG when only receiving the channel quality difference SR through the conversion relationship between each scheduling grant information. Thetotal or auxiliary stream scheduling permission information SGsecondary completes the update process, thereby achieving the effect of more accurate E-TFC selection of the auxiliary stream, and further achieving the effect that the base station can effectively control uplink interference.
