Description
Translated fromChinese技术领域technical field
本申请涉及通信领域，并且更具体地，尤其涉及一种通信方法和通信装置。The present application relates to the field of communication, and more particularly, to a communication method and a communication device.
背景技术Background technique
在第五代移动通信系统(the 5th generation，5G)的版本15(release 15)中，已经可以支持物理下行共享信道(physical downlink shared channel，PDSCH)的跨时隙调度(cross-slot scheduling)，即物理下行控制信道(physical downlink controlchannel，PDCCH)可以与其调度的PDSCH位于不同的时隙中。In the release 15 (release 15) of the fifth generation mobile communication system (the 5th generation, 5G), the cross-slot scheduling (cross-slot scheduling) of the physical downlink shared channel (PDSCH) can already be supported, That is, a physical downlink control channel (physical downlink control channel, PDCCH) may be located in a different time slot with its scheduled PDSCH.
与同时隙调度相比，跨时隙调度更加有利于终端设备(user equipment，UE)省电。例如，对于同时隙调度，UE在PDCCH译码期间(即译码解出DCI之前)，无法获知这段时间的数据是否会被调度到，所以必须缓存这段时间的下行数据接收缓存、并保持射频等前端模块打开，相应地，UE会消耗掉更多的能量；而对于跨时隙调度，UE可以至少提前一个时隙知道本时隙是否有调度，若无调度，则此时UE可以关闭下行数据射频等前端模块及下行数据接收缓存以实现省电。Compared with time-slot scheduling, cross-slot scheduling is more conducive to power saving of terminal equipment (user equipment, UE). For example, for co-slot scheduling, during the PDCCH decoding period (that is, before decoding and decoding the DCI), the UE cannot know whether the data during this period will be scheduled, so the downlink data reception buffer during this period must be buffered and kept When the front-end modules such as radio frequency are turned on, the UE will consume more energy accordingly. For cross-slot scheduling, the UE can know at least one time slot in advance whether the current time slot is scheduled. If there is no scheduling, the UE can be turned off at this time. Front-end modules such as downlink data radio frequency and downlink data receiving buffer to save power.
但可能会存在一些特殊情况，例如，PDCCH可能会触发非周期信道状态信息参考信号(aperiodic channel state information reference signal，A-CSI-RS)，因此UE需要接收A-CSI-RS；或者，在某些PDCCH检测时机(monitoring occasion)，UE需要检测第一系统消息块(system information block 1，SIB1)、随机接入响应或终端设备冲突解决标识。在这些情况下，UE需要在本时隙接收下行数据，不利于UE省电。However, there may be some special cases. For example, the PDCCH may trigger an aperiodic channel state information reference signal (A-CSI-RS), so the UE needs to receive A-CSI-RS; On some PDCCH monitoring occasions (monitoring occasions), the UE needs to detect the first system information block (system information block 1, SIB1), the random access response or the terminal equipment conflict resolution identifier. In these cases, the UE needs to receive downlink data in this time slot, which is not conducive to the power saving of the UE.

Generally, the wireless air interface is required to achieve 99.999% transmission reliability within 1 millisecond (ms).
在无线通信系统中，PDSCH的调度方式是通过下行控制信息(downlink controlinformation，DCI)进行动态指示。例如，DCI中可以包括4比特(bit)的时域资源分配(timedomain resource assignment)字段，所述DCI可以动态地指示16个PDSCH时域资源中的一个。可选地，所述16个PDSCH时域资源可以是网络设备半静态配置的，也可以是预先设置的或协议中规定的。In a wireless communication system, a PDSCH scheduling method is dynamically indicated through downlink control information (downlink control information, DCI). For example, a 4-bit time domain resource assignment (timedomain resource assignment) field may be included in the DCI, and the DCI may dynamically indicate one of 16 PDSCH time domain resources. Optionally, the 16 PDSCH time domain resources may be semi-statically configured by the network device, or may be preset or specified in a protocol.
现有的无线通信系统可以支持同时隙调度和跨时隙调度(cross-slotscheduling)两种调度方式。Existing wireless communication systems can support two scheduling methods: time-slot scheduling and cross-slot scheduling.
同时隙调度是指物理下行控制信道(physical downlink control channel，PDCCH)与所述PDCCH调度的物理下行共享信道(physical downlink shared channel，PDSCH)或其他下行信号位于同一个时隙。如图2所示，在无数据调度情况下，对于同时隙调度，终端设备在PDCCH译码期间(即译码解出DCI之前)，无法获知这段时间的数据是否会被调度到，所以必须缓存这段时间的下行数据接收缓存、并保持射频等前端模块打开，相应地，终端设备会消耗掉更多的能量。Co-slot scheduling means that a physical downlink control channel (PDCCH) and a physical downlink shared channel (PDSCH) scheduled by the PDCCH or other downlink signals are located in the same time slot. As shown in Figure 2, in the case of no data scheduling, for the time slot scheduling, the terminal equipment cannot know whether the data during this period will be scheduled during the PDCCH decoding period (that is, before decoding and decoding the DCI), so it must be Buffer the downlink data reception buffer for this period of time, and keep the front-end modules such as the radio frequency open. Accordingly, the terminal device will consume more energy.
跨时隙调度是指PDCCH与所述PDCCH调度的PDSCH或其他下行信号位于不同的时隙。如图2所示，在无数据调度情况下，对于跨时隙调度，终端设备可以至少提前一个时隙知道本时隙无调度，此时，终端设备可以关闭下行数据射频等前端模块及下行数据接收缓存以实现省电。Scheduling across time slots means that the PDCCH and the PDSCH or other downlink signals scheduled by the PDCCH are located in different time slots. As shown in Figure 2, in the case of no data scheduling, for cross-slot scheduling, the terminal device can know that this time slot is not scheduled at least one time slot in advance. At this time, the terminal device can turn off the downlink data radio and other front-end modules and downlink data. Receive buffer for power saving.
PDSCH时域资源中可以包括K0参数，其中，K0参数可以表示PDCCH资源与所述PDCCH所调度的PDSCH资源相距的时隙个数，或者说，PDCCH资源所调度的PDSCH资源相对于所述PDCCH偏移的时隙个数。这里，如果PDCCH资源或PDSCH资源占用多于一个时隙，按照其中的首个时隙计算相距/偏移的时隙个数。例如，假如PDCCH资源占用时隙n，所述PDCCH资源所调度的PDSCH资源占用时隙n+3，则所述PDCCH资源与所述PDSCH资源相距的时隙个数为3，K0＝3。又例如，假如PDCCH资源占用时隙n，所述PDCCH资源所调度的PDSCH资源占用时隙n+2和时隙n+3，则所述PDCCH资源与所述PDSCH资源相距的时隙个数为2，K0＝2。The PDSCH time domain resource may include a K0 parameter, where the K0 parameter may indicate the number of time slots between the PDCCH resource and the PDSCH resource scheduled by the PDCCH, or, in other words, the PDSCH resource scheduled by the PDCCH resource is offset relative to the PDCCH The number of time slots to be shifted. Here, if the PDCCH resource or the PDSCH resource occupies more than one time slot, the distance/offset number of time slots is calculated according to the first time slot among them. For example, if the PDCCH resource occupies time slot n, and the PDSCH resource scheduled by the PDCCH resource occupies time slot n+3, the number of time slots between the PDCCH resource and the PDSCH resource is 3, and K0=3. For another example, if the PDCCH resource occupies time slot n, and the PDSCH resource scheduled by the PDCCH resource occupies time slot n+2 and time slot n+3, the number of time slots between the PDCCH resource and the PDSCH resource is 2, K0=2.
例如，K0＝0可以表示PDCCH资源与所述PDCCH所调度的PDSCH资源在同一个时隙，如图2中的同时隙调度。K0>0可以表示跨时隙调度，例如，K0＝1可以表示PDCCH资源与所述PDCCH所调度的PDSCH资源相距一个时隙，如图2中的跨时隙调度；相应地，K0＝2可以表示PDCCH资源与所述PDCCH所调度的PDSCH资源相距两个时隙。For example, K0=0 may indicate that the PDCCH resource and the PDSCH resource scheduled by the PDCCH are in the same time slot, such as the time slot scheduling in FIG. 2 . K0>0 may indicate cross-slot scheduling, for example, K0=1 may indicate that the PDCCH resource is one time slot away from the PDSCH resource scheduled by the PDCCH, as shown in cross-slot scheduling in FIG. 2; correspondingly, K0=2 may Indicates that the PDCCH resource is two slots away from the PDSCH resource scheduled by the PDCCH.
在本申请中，网络设备可以通过配置使PDSCH时域资源中的K0参数满足：K0>0。此时，终端设备可以在译码出DCI之前，提前知道该调度是跨时隙调度，从而可以关闭下行数据射频等前端模块及下行数据接收缓存以实现省电。In this application, the network device can make the K0 parameter in the PDSCH time domain resource satisfy: K0>0 through configuration. At this time, the terminal device can know in advance that the scheduling is a cross-slot scheduling before decoding the DCI, so that the front-end modules such as the downlink data radio frequency and the downlink data receiving buffer can be turned off to save power.
但在通信过程中，可能会存在一些特殊情况，例如，PDCCH可能会触发非周期信道状态信息参考信号(aperiodic channel state information reference signal，A-CSI-RS)，相应地，终端设备需要接收A-CSI-RS；或者，在某些PDCCH检测时机(monitoringoccasion)，终端设备需要检测第一系统消息块(system information block 1，SIB1)、随机接入响应或终端设备冲突解决标识。在这些情况下，终端设备需要在本时隙接收下行数据，不利于终端设备省电。However, in the communication process, there may be some special cases. For example, the PDCCH may trigger an aperiodic channel state information reference signal (A-CSI-RS). Accordingly, the terminal device needs to receive A-CSI-RS. CSI-RS; or, at certain PDCCH monitoring occasions (monitoring occasions), the terminal device needs to detect the first system information block (system information block 1, SIB1), the random access response or the terminal device conflict resolution identifier. In these cases, the terminal equipment needs to receive downlink data in this time slot, which is not conducive to the power saving of the terminal equipment.
因此，本申请实施例提出了一种通信方法，能够保证终端设备在省电的同时正常接收下行信号，从而使终端设备合理地省电。Therefore, the embodiment of the present application proposes a communication method, which can ensure that the terminal device normally receives downlink signals while saving power, so that the terminal device can reasonably save power.

方式一：method one:
首先，需要保证所述多个候选第一时域资源中的至少一个候选第一时域资源相对于所述第二时域资源偏移的时隙的数量大于或等于所述第一阈值，其余候选第一时域资源相对于所述第二时域资源偏移的时隙的数量可以小于所述第一阈值。First, it needs to ensure that the number of time slots offset by at least one candidate first time domain resource relative to the second time domain resource in the multiple candidate first time domain resources is greater than or equal to the first threshold, and the rest The number of time slots at which the candidate first time domain resource is offset relative to the second time domain resource may be less than the first threshold.

Wherein, the one or more A-CSI-RSs may include CSI-RSs used for interference measurement.
方式二：Method two:
所述网络设备可以发送第一信息，所述第一信息用于更新第一时域资源的多个候选第一时域资源的第一参数。这里，在所述多个候选第一时域资源之中，全部候选第一时域资源的第一参数可以均被更新，也可以仅有更新部分候选第一时域资源的第一参数被更新。The network device may send first information, where the first information is used to update the first parameters of the multiple candidate first time domain resources of the first time domain resources.

It should be understood that, here, "update" is regarded as describing the whole of the plurality of candidate first time domain resources, that is, the network device determines that the alternatives of the first time domain resources are not limited to the ones that are actually updated. Instead, the candidate first time domain resource includes the first time domain resource that is actually updated and the first time domain resource that does not need to be updated.
应理解的是，虽然使用了“更新”进行描述，但所述终端设备和所述网络设备可能不会真的去更新所述第一配置信息。比如，所述终端设备可以在确定所述第一PDCCH指示了哪个候选第一时域资源后，再根据所述第一信息和这个候选第一时域资源除了时隙偏移量以外的其他信息确定所述第一时域资源；所述网络设备可以在确定第一PDCCH指示哪个候选第一时域资源时将之前发送的所述第一信息考虑在内。当然，所述终端设备和所述网络设备也可以实际更新所述第一配置信息，例如，更新表1、表2和表3。It should be understood that although "update" is used for description, the terminal device and the network device may not actually update the first configuration information. For example, after determining which candidate first time domain resource is indicated by the first PDCCH, the terminal device may, after determining which candidate first time domain resource indicates, according to the first information and other information other than the time slot offset of the candidate first time domain resource determining the first time domain resource; the network device may take the previously sent first information into consideration when determining which candidate first time domain resource the first PDCCH indicates.

In this case, for example, the network device may update the row index in Table 1. For the time domain resource that is "1", K0 is set to be greater than or equal to 1, so that the time interval between the time domain resource and the second time domain resource is greater than or equal to the first threshold.
可选地，所述第一信息可以为更新后的时隙偏移量。这里，第一信息可以仅为需要更新的候选第一时域资源的更新后的时隙偏移量，也可以为全部候选第一时域资源的时隙偏移量，此时，第一信息包括需要更新的候选第一时域资源的更新后的时隙偏移量、以及无需更新的候选第一时域资源的时隙偏移量。Optionally, the first information may be an updated time slot offset. Here, the first information may only be the updated time slot offsets of the candidate first time domain resources that need to be updated, or may be the time slot offsets of all the candidate first time domain resources.

Here, the first information may only be the difference between the updated time slot offset of the candidate first time domain resource that needs to be updated and the original time slot offset, or may be all the candidate first time domain resources The difference between the time slot offset and the original time slot offset of other than the difference between the slot offsets of , fill other positions with 0.
或者，所述第一信息可以为所述第一阈值。作为示例，所述终端设备可以在确定所述第一PDCCH指示了哪个候选第一时域资源后，确定所述指示的候选第一时域资源与所述第二PDCCH的时间间隔是否大于或等于所述第一阈值，如果其时间间隔大于所述第一阈值，则将所述指示的候选第一时域资源确定为所述第一时域资源，如果其时间间隔小于所述第一阈值，则将所述第一时域资源确定为其他参数与所述指示的候选第一时域资源相同，但与所述第二时域资源的时间间隔为所述第一阈值的时域资源。或者，所述终端设备可以在确定所述第一PDCCH指示了哪个候选第一时域资源后，直接将所述第一时域资源确定为其他参数与所述指示的候选第一时域资源相同，但与所述第二时域资源的时间间隔为所述第一阈值的时域资源。Alternatively, the first information may be the first threshold.
