Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.
First, background and technical terms in the embodiments of the present application will be described.
CSI-RS, channel state information reference signal (Channel-State Information REFERENCE SIGNAL);
TRS phase reference signal (TRACKING REFERENCE SIGNAL), a multi-periodic CSI-RS can be understood.
PAGING MASSAGE the paging message has the functions of (1) sending a call request to the terminal equipment in the RRC_IDLE state, (2) notifying the terminal equipment in the RRC_IDLE/INACTIVE and RRC_CONNECTED states that the system information is changed, (3) notifying the earthquake tsunami, instructing the terminal equipment to start receiving ETWS PRIMARY notification and/or the ETWS second notification, and instructing the terminal equipment to start receiving CMAS notification. If the terminal equipment is paged or the system information is updated or earthquake and tsunami occurs, the base station firstly transmits a wake-up signal, and after the terminal equipment detects the wake-up signal, the terminal equipment monitors the paging PDCCH and receives the paging message, otherwise, the terminal equipment always keeps a sleep state so as to achieve the purpose of saving electricity. In NR, the UE may use Discontinuous Reception (DRX) in rrc_idle and rrc_inactive states in order to reduce power consumption. The UE periodically (paging cycle is DRX cycle) listens for paging occasions (Paging Occasion, PO).
In addition, the UE needs to perform time-frequency synchronization and AGC (automatic gain control) adjustment with a reference signal (e.g., SSB) before receiving Paging.
In order to save the power consumption of the terminal equipment, in a DRX scene, each PO can be associated with one PEI, and before monitoring the PO, the terminal equipment can receive the PEI to determine whether the PO associated with the PEI needs to be monitored or not so as to achieve the purpose of saving the power consumption;
In eDRX (Extended idle mode DRX) scenario, there is a paging time Window PTW (PAGING TIME Window) in each eDRX cycle, and the terminal device listens to the paging channel in the PTW according to the DRX cycle (the DRX cycle time is short, and the terminal device can be considered not to sleep and can be reached all the time) so as to receive downlink data, and the rest of the time is when the terminal device is in sleep state. I.e. in eDRX (Extended idle mode DRX) scenario, one PEI may associate multiple POs (assuming m POs), i.e. the terminal device receives the PEI indication, and may determine whether the subsequent m POs needs to monitor.
In terms of the paging rate (10%) of the terminal equipment group in the existing network, generally, the probability PEI above 90% indicates that the terminal equipment does not wake up to monitor the PDCCH at its corresponding PO.
The following will also describe the activity of the terminal device in idle/inactive state, where the terminal device basically performs measurement activity of the serving cell every DRX cycle for the purpose of cell reselection, and for the purpose of time-frequency synchronization and automatic gain control (Automatic Gain Control, AGC) adjustment before monitoring the PO.
In the idle/active state, the terminal device needs to perform time-frequency synchronization with a plurality of (e.g., 3) synchronization signal blocks (SS/PBCH block, SSB), AGC adjustment, and radio resource management (Radio Resource Management, RRM) measurements for the serving cell before receiving Paging in each DRX cycle. Since SSBs are periodically transmitted (the period size of which is cell level, i.e. the SSB transmission period of one cell is the same), it cannot be guaranteed that every PO (the period of which is terminal equipment level, each terminal equipment has its specific PO period) is close to a certain SSB, if the distance between the SSB and the PO is large, the terminal equipment needs to wake up multiple times for receiving paging (here, assuming that 2 SSBs are needed to complete time-frequency synchronization, AGC adjustment and RRM measurement for the serving cell, 3 times for time-frequency synchronization/AGC adjustment/serving cell RRM measurement, 1 time for monitoring the PO), if the SSB is close to the PO, the terminal equipment only needs to wake up 2 times to complete time-frequency synchronization, AGC adjustment, measurement of the serving cell and reception of paging.
Further, frequent wake-up of the terminal device in idle/inactive state to perform related activities (i.e. time-frequency synchronization, AGC adjustment and measurement of serving cell) may increase the power consumption of the terminal device. The current 3GPP solution is that the network side configures periodic TRS/CSI-RS transmission resources for the terminal equipment in the idle/inactive state through system broadcast information, i.e. the terminal equipment in the idle/inactive state can share TRS/CSI-RS with the terminal equipment in the connected state. The terminal equipment in idle/inactive state can utilize TRS/CSI-RS to complete the activities such as AGC adjustment/time-frequency synchronization, so as to reduce the wake-up times of the terminal equipment, namely, the terminal equipment can integrate the time-frequency synchronization, AGC adjustment and measurement of a serving cell through the TRS/CSI-RS, and reduce the wake-up times of the UE.
For example, as shown in fig. 1, there is an additional reference signal (abbreviated ARS, i.e., TRS/CSI-RS) in front of (and close to) the PO, and the UE only needs to wake up 2 times to complete time-frequency synchronization, measurement and Paging reception. But in the idle/inactive state, the availability of the TRS/CSI-RS resource needs to be indicated by the network side to the terminal device, that is, the terminal device needs to determine whether the resource of the subsequent TRS/CSI-RS is valid by receiving the TRS/CSI-RS validity indication message issued by the network side in advance (that is, determine whether the base station sends the TRS/CSI-RS at the transmission opportunity of the subsequent TRS/CSI-RS).
In order to more flexibly indicate the validity of the TRS/CSI-RS, reduce bit overhead, power consumption of terminal equipment and the like, the embodiment of the application provides a message transmission method and a related device, which can dynamically and flexibly indicate the availability of reference signal resources in a PAGING DCI and PEI joint indication mode, and reduce the power consumption and the bit overhead of the terminal equipment.

A message transmission method in the embodiment of the present application is described below with reference to fig. 3, and fig. 3 is a schematic flow chart of the message transmission method provided in the embodiment of the present application, which is applied to a terminal device, and specifically includes the following steps:
step 301, obtaining configuration information.
The configuration information comprises duration information and transmission resource configuration information, wherein the duration information is used for indicating the effective duration of the first message, and the transmission resource configuration information comprises configuration information of at least one transmission resource subset and configuration information of at least one transmission resource contained in each transmission resource subset;
The configuration information may be obtained by receiving system information or RRC signaling from the network side, where each transmission resource subset includes at least one transmission resource, and it may be understood that in the embodiment of the present application, the transmission resource is a TRS/CRI-RS resource or a TRS/CRI-RS resource set, where the duration information may include a first duration T1 or a second duration T2, T1 is an integer multiple of a paging cycle, and a unit of T2 may be a paging cycle, a millisecond, a time slot, a subframe, a frame, etc., and two message transmission modes exist according to different configured duration information, which is not described herein in detail in the following steps.
By acquiring the configuration information, two ways of receiving messages with the effective duration of T1 and the effective duration of T2 can be provided for the terminal equipment in the scene of indicating the availability of the reference signals, so that the flexibility of indicating the availability of the reference signals is improved.
Step 302, receiving the first message.
The first message is used to indicate a first transmission resource subset in an active state in the at least one transmission resource subset, for example, if the network side configures a transmission resource subsets through configuration information, a is a natural number greater than 1, b first transmission resource subsets in an active state exist in the a transmission resource subsets, b is a natural number less than or equal to a, and then the terminal device may determine b first transmission resource subsets existing in the a transmission resource subsets by receiving the first message.
Specifically, the first message may include first bit field information in the paging downlink control information PAGING DCI, further, the first bit field information includes a first bit value, where the first bit value represents a value of each bit in a first bit field, and each bit in the first bit field has a first mapping relationship with the first transmission resource subset, where the first mapping relationship is indicated by system information or RRC signaling, and the first bit field information may also include a first bit field value, where the first bit field value represents a value of the first bit field. The terminal device may receive PAGING DCI and read the first bit value or the first bit field value, which is not specifically limited herein.
Further, it is explained here how the first bit field information indicates whether the transmission resource subset is in an active state, it is understood that the network side may determine the number of bits in the first bit field according to the number of the transmission resource subsets, i.e. the number of the transmission resource subsets is equal to the number of bits in the first bit field. In a possible embodiment, a first mapping relationship may be established between each bit in the first bit field and a transmission resource subset configured on each network side, that is, each bit corresponds to one transmission resource subset, where when the bit value is 1, the terminal device may determine that the corresponding transmission resource subset is in an active state, where the transmission resource subset is the first transmission resource subset, and when the bit value is 0, the terminal device may determine that the corresponding transmission resource subset is in an inactive state, where the transmission resource subset is not the first transmission resource subset. In another possible embodiment, the network side may directly take the first bit field as a whole, for example, if the number of the transmission resource subsets is three, namely C1, C2, and C3, then the first bit field takes the value of 00 to indicate that all the three transmission resource subsets are inactive, and there is no first transmission resource subset, the first bit field takes the value of 01 to indicate that C1 is the first transmission resource subset, the first bit field takes the value of 10 to indicate that C2 is the first transmission resource subset, and the first bit field takes the value of 11 to indicate that C3 is the first transmission resource subset. The terminal device may determine a first subset of transmission resources of the at least one subset of transmission resources configured at the network side by reading the first bit field value.
In a possible embodiment, when the configured duration information is T1, the terminal device may receive PAGING DCI at a first paging occasion PO1 to read the first bit value or the first bit field value, where the first paging occasion PO1 is determined according to a paging parameter and the first duration T1, where the paging parameter includes a paging frame Number N, a start paging frame Number pf_offset, and a user identifier ue_id in the paging cycle in the existing protocol, and is used to determine a paging frame PF and a first paging index i_s, where the paging frame represents a system frame Number SFN (SYSTEM FRAME Number) corresponding to the first paging occasion PO1, and the first paging index i_s represents an index of the first paging occasion in the paging frame.
The specific steps for determining PO1 are as follows:
firstly, determining PF according to PF_offet, T1, N and UE_ID, namely determining SFN where PO1 is located, and the formula is as follows:
(SFN+PF_offset)mod T1=(T1 div N)*(UE_ID mod N)
then, a first paging occasion index PO1 ndex, which is specifically used to receive the TRS/CSI-RS availability indication, is determined in the PF according to the parameter i_s, as follows:
i_s=floor(UE_ID/N)mod Ns
Wherein, the
SFN is system frame Number SYSTEM FRAME Number;
PF_offset, the starting time interval used for determining PF in the existing protocol, namely the starting frame number;
n is the number of PFs in the Paging cycle in the existing protocol;
UE_ID:5G-S-TMSI mod 1024;
i_s is the index of the determined PO1 in PF (starting from 0);
t1 is effective duration T1 of TRS/CSI-RS availability indication;
Ns is the number of PO in a PF.
Further, the terminal device may receive PAGING DCI the PO1 to read the first bit value or the first bit field value, and determine, according to the first bit value or the first bit field value, a first transmission resource subset in an active state among all transmission resource subsets configured at the network side.
In a possible embodiment, when the configured duration information is the second duration T2, and when any paging occasion PO receives PAGING DCI and reads the first bit value or the first bit field value, a Timer is triggered, where the timing duration of the Timer is equal to T2, it may be understood that the information of PAGING DCI in T2 is valid, and once the Timer expires, the terminal device needs to re-receive PAGING DCI to determine the first transmission resource subset of all the transmission resource subsets configured on the network side. The terminal device may receive PAGING DCI and read the first bit value or the first bit field value to determine a first transmission resource subset in an active state of all transmission resource subsets configured at the network side, which is not described herein.
It can be seen that, two effective durations are set, the first message is received in two ways, the receiving mode can be flexibly configured according to the actual scene, flexibility of receiving the first message is improved, the first transmission resource subset in the active state is determined through PAGING DCI, efficiency of indicating the availability of the reference signal resource subsequently can be improved, and power consumption of the terminal device is reduced while bit cost is reduced.
And step 303, reading the second message in the effective duration.
The second message is used to indicate an availability status of each first transmission resource in the first transmission resource subset, and it can be understood that each first transmission resource subset includes at least one first transmission resource, where the first transmission resource is a reference signal TRS/CRI-RS resource or a reference signal TRS/CRI-RS resource set, and the availability status may be available or unavailable. The second message may include second bit field information in the paging advance indication PEI.
Specifically, the second bit field information includes a second bit value, where the second bit value represents a value of each bit in a second bit field, and each bit in the second bit field has a second mapping relationship with a first transmission resource in the first transmission resource subset, where the second mapping relationship is indicated by the system information or the RRC signaling, and the second bit field information may also include a second bit field value, where the second bit field value represents a value of the second bit field. The terminal device may receive the PEI and read the second bit value or the second bit field value, which is not specifically limited herein.
Further, it is explained here how the second bit field information indicates the availability status of each first transmission resource in the first transmission resource subsets, it is understood that the network side may determine the number of bits in the second bit field according to the number of first transmission resources in each first transmission resource subset, i.e. the number of first transmission resources in each first transmission resource subset is equal to the number of bits in the second bit field. In a possible embodiment, a second mapping relationship may be established between each bit in the second bit domain and the first transmission resources in each first transmission resource subset, that is, each bit corresponds to one first transmission resource in the first transmission resource subset, where the availability status of the corresponding first transmission resource is determined to be available when the bit value is 1, and where the availability status of the corresponding first transmission resource is determined to be unavailable when the bit value is 0. In another possible embodiment, the network side may directly perform overall value of the second bit field to obtain the value of the second bit field, for example, if a certain first transmission resource subset includes three first transmission resources, s1, s2, s3, respectively, the value of the second bit field is 00, which indicates that none of the three first transmission resources is available, the value of the second bit field is 01, which indicates that s1 is available, s2 and s3 are unavailable, the value of the second bit field is 10, which indicates that s2 is available, s1 and s3 are unavailable, and the value of the second bit field is 11, which indicates that s3 is available, s1 and s2 are unavailable. The terminal device may read the second bit value or the second bit field value within the valid duration to determine the availability status of each first transmission resource in the first transmission resource subset, which is not described herein.
In a possible embodiment, when the duration information is T1, PEI may be received in T1 after PO1 to read the second bit value or the second bit field value, and determine the availability of each first transmission resource in the first transmission resource subset.
For example, as shown in fig. 4A, fig. 4A is a schematic diagram of a reference signal availability indication provided by the embodiment of the present application, it may be seen that, when a terminal device receives and reads PAGING DCI at PO1, the PAGING DCI indicates that C1 is a first subset of transmission resources, and C1 includes two first transmission resources, S1 and S2 respectively, then the terminal device may receive PEI in an effective duration T1 and read a second bit value at this time, and determine that S1 and S2 are both available when the second bit value is 11, and determine that S1 is unavailable and S2 is available when the second bit value is 01, and determine that S1 and S2 are both unavailable when the second bit value is 00.
As shown in fig. 4B, fig. 4B is a schematic diagram of another reference signal availability indication provided by the embodiment of the present application, it may be seen that, when a PO1 is received and read PAGING DCI, the PAGING DCI indicates that C1 and C2 are a first subset of transmission resources, two first transmission resources are included in C1, S1 and S2 are included in C2, two first transmission resources are included in C2, S3 and S4 are included in C1 respectively, then the terminal device may receive PEI in an effective duration T1, and read a second bit value at this time to determine availability of each first transmission resource in C1 and C2, when the second bit value is 11, determine that S1 and S2 in C1 are available, S3 and S4 in C2 are available, when the second bit value is 01, determine that S1 in C1 is unavailable, S3 in C2 is unavailable, and S4 is unavailable, and when the second bit value is 00, determine that S1 and S2 are unavailable. I.e. each first subset of transmission resources determines the availability of each first transmission resource in each first subset of transmission resources according to the second bit field information in the PEI.
The second bit field may be referred to the above method, and will not be described herein.
In a possible embodiment, when the duration information is T2, the PEI may be received during a Timer timing duration T2 to read the second bit value or the second bit field value, and determine an availability of each first transmission resource in the first transmission resource subset.
For example, as shown in fig. 4C, fig. 4C is a schematic diagram of another reference signal availability indication provided by the embodiment of the present application, it may be seen that when any one PO receives and reads PAGING DCI, the terminal device triggers a Timer, and this PAGING DCI indicates that C1 is a first subset of transmission resources, and C1 includes two first transmission resources, respectively S1 and S2, and then the terminal device may receive PEI during the running period of the Timer, i.e., T2, and read a second bit value at this time, and determine that S1 and S2 are both available when the second bit value is 11, and determine that S1 is unavailable when the second bit value is 01, and determine that S1 and S2 are both unavailable when the second bit value is 00.
As shown in fig. 4D, fig. 4D is a schematic diagram of another reference signal availability indication provided by the embodiment of the present application, it may be seen that when any one PO receives and reads PAGING DCI, the terminal device triggers a Timer, where PAGING DCI indicates that C1 and C2 are a first subset of transmission resources, C1 includes two first transmission resources, S1 and S2, and C2 includes two first transmission resources, S3 and S4, respectively, and the terminal device may receive PEI during running of the Timer, i.e., T2, and read a second bit value at this time, and when the second bit value is 11, determine that S1 and S2 in C1 are available, S3 and S4 in C2 are available, and when the second bit value is 01, determine that S1 in C1 is unavailable S2, and when the second bit value is 00, S3 in C2 is unavailable, and S3 in C2 is unavailable.
The second bit field may be referred to the above method, and will not be described herein.
It can be seen that, by reading the second message within the effective duration, the reference signal availability indication policies of two effective durations are also applicable, so that the availability of each transmission resource can be flexibly indicated by combining the first message and the second message, and the power consumption and bit overhead of the terminal device are greatly reduced.
The following describes another message transmission method in the embodiment of the present application with reference to fig. 5, and fig. 5 is a schematic flow chart of another message transmission method provided in the embodiment of the present application, which is applied to an access network device, and specifically includes the following steps:
step 501, sending configuration information, a first message and a second message.
The configuration message may be determined through system information or RRC signaling, where the configuration message includes duration information and transmission resource configuration information, the duration information includes a first duration T1 or a second duration T2, which is used to indicate an effective duration of the first message and an effective reading time of the second message, the transmission resource configuration information includes configuration information of at least one transmission resource subset and configuration information of at least one transmission resource contained in each transmission resource subset, the first message is used to indicate a first transmission resource subset in an active state in the at least one transmission resource subset, and the second message is used to indicate an availability status of each first transmission resource in the first transmission resource subset, where the first transmission resource is a reference signal resource or a reference signal resource set, and it may be understood that a transmission resource in an embodiment of the present application is a TRS/CRI-RS resource or a TRS/CRI-RS resource set.
Specifically, the first message includes first bit field information in paging downlink control information PAGING DCI, and the second message includes second bit field information in paging advance indicator PEI. The first bit field information may include a first bit value or a first bit field value, and the second bit field information may include a second bit value or a second bit field value.
In a possible embodiment, the network side may determine the number of bits in the first bit domain according to the number of the transmission resource subsets, and then establish a first mapping relationship between each of the transmission resource subsets and the bits in the first bit domain, where the first mapping relationship is indicated by the system information or the RRC signaling. As such, the value of each bit in the first bit field may indicate whether the corresponding subset of transmission resources is in an active state. For example, the network side configures 3 reference signal resource sets, respectively, C1, C2, and C3, and determines that the number of bits in the first bit field is 3, sets that the first bit corresponds to C1, the second bit corresponds to C2, the third bit corresponds to C3, when the value of the bit is 1, it indicates that the transmission resource subset corresponding to the bit is the first transmission resource subset in the active state, and when the value of the bit is 0, it indicates that the transmission resource subset corresponding to the bit is not in the active state, for example, when the value of the first bit is 110, it indicates that C1 and C2 are the first transmission resource subset, and C3 is not the first transmission resource subset, for example, when the value of the first bit is 000, it indicates that all of C1, C2, and C3 are not the first transmission resource subset. And will not be described in detail herein.
In one possible embodiment, the network side may directly take the first bit field as a whole, for example, if the number of the transmission resource subsets is three, namely C1, C2 and C3, then the first bit field takes the value of 00 to indicate that all the three transmission resource subsets are inactive and there is no first transmission resource subset, the first bit field takes the value of 01 to indicate that C1 is the first transmission resource subset, the first bit field takes the value of 10 to indicate that C2 is the first transmission resource subset, and the first bit field takes the value of 11 to indicate that C3 is the first transmission resource subset.
In a possible embodiment, the network side may determine the number of bits in the second bit field according to the number of first transmission resources in each first transmission resource subset, i.e. the number of first transmission resources in each first transmission resource subset is equal to the number of bits in the second bit field. In one possible embodiment, a second mapping relationship may be established between each bit in the second bit domain and each first transmission resource, that is, each bit corresponds to one first transmission resource, where the availability status of the corresponding first transmission resource is determined to be available when the bit value is 1, and the availability status of the corresponding first transmission resource is determined to be unavailable when the bit value is 0.
In another possible embodiment, the network side may directly perform overall value of the second bit field to obtain the value of the second bit field, for example, if a certain first transmission resource subset includes three first transmission resources, s1, s2, s3, respectively, the value of the second bit field is 00, which indicates that none of the three first transmission resources is available, the value of the second bit field is 01, which indicates that s1 is available, s2 and s3 are unavailable, the value of the second bit field is 10, which indicates that s2 is available, s1 and s3 are unavailable, and the value of the second bit field is 11, which indicates that s3 is available, s1 and s2 are unavailable. The terminal device may read the second bit value or the second bit field value within the valid duration to determine the availability status of each first transmission resource in the first transmission resource subset, which is not described herein.
By the method, the availability of each transmission resource can be flexibly indicated by combining the first message and the second message, and the power consumption and bit cost of the terminal equipment are greatly reduced.
In order to more clearly describe the message transmission method in the embodiment of the present application, another message transmission method in the embodiment of the present application is described below with reference to fig. 6, and fig. 6 is another message transmission method provided in the embodiment of the present application, applied to a terminal device and an access network device, that is, a UE side and a network side, and specifically includes the following steps:

Step 604, a first message is received.
Step 605, the second message is read for a valid duration.
The steps not described in detail above may refer to the descriptions of the steps of the foregoing method, and are not described herein.
In a possible embodiment, when the duration information is T1, the corresponding PAGING DCI is not received at the first paging occasion, or when the first paging occasion PO1 receives the corresponding PAGING DCI but the first bit domain information indicates that the first subset of transmission resources does not exist in the at least one subset of transmission resources, the second bit domain information may be ignored for the first duration T1, and the availability status of the first transmission resource is unavailable.
In a possible embodiment, when the duration information is T1 and the corresponding PAGING DCI is not received at the first paging occasion, the second subset of transmission resources in the active state of the at least one subset of transmission resources may be determined according to the first bit field information in PAGING DCI received at a second paging occasion, where the second paging occasion PO2 is determined before the first paging occasion PO1, and is also determined according to the paging parameter and the first duration, simply stated, PO2 is a paging occasion determined in a previous paging cycle of PO1, and will not be described herein;
next, PEI may be received during the first period T1 and the second bit value or the second bit field value may be read to determine an availability status of each transmission resource in the second subset of transmission resources, where the transmission resource is a reference signal resource or a reference signal resource set.
In an alternative embodiment, the second bit field information is ignored and the availability status of the third transmission resource is unavailable, either if PAGING DCI is not received after the timer exceeds the second time period, or if PAGING DCI is received after the timer exceeds the second time period but the first bit field information indicates that the first subset of transmission resources is absent from the at least one subset of transmission resources.
In summary, the message transmission method disclosed in the embodiment of the present application can flexibly indicate the availability of each transmission resource by combining the first message and the second message, thereby greatly reducing the power consumption and bit overhead of the terminal device.
