In some embodiments, the access network device may be composed of a Central Unit (CU) and a Distributed Unit (DU), where the CU may also be referred to as a control unit (control unit), and the structure of the CU-DU may be used to split the protocol layers of the access network device, where functions of part of the protocol layers are centrally controlled by the CU, and functions of the rest of all the protocol layers are distributed in the DU, and the DU is centrally controlled by the CU, but is not limited thereto.

In some embodiments, the core network device may be a device, including one or more network elements, or may be a plurality of devices or a device group, including all or part of one or more network elements. The network element may be virtual or physical. The core network comprises, for example, at least one of an evolved packet core (Evolved Packet Core, EPC), a 5G core network (5G Core Network,5GCN), a next generation core (Next Generation Core, NGC).

In some embodiments, in a dynamic time division duplex (DTDD, dynamic Time Division Duplex) scenario, to improve the performance of the corresponding uplink communication, the proportion of the corresponding uplink (UL, up Link) transmission time slot increases correspondingly in the TDD configuration. Referring to fig. 1b, if the neighboring cells adopt the previous TDD structure, the transmission directions of the corresponding two cells are inconsistent, resulting in serious interference.

In some embodiments, to reduce Cross-link interference (CLI, cross-Link Interference), an interfered terminal (victim) receives a CLI Reference Signal (CLI-RS) at a particular time to make CLI measurements for subsequent further CLI suppression (interference) operations.

In some embodiments, cell-Defining SSB (CD-SSB) transmissions of different cells may have corresponding overlaps (overlapping) with CLI measurements on time-frequency domain resources. If the interfered base station uses CD-SSB to perform CLI measurement (e.g., flexible time slot) on the overlapped time-frequency domain resources, a conflict of resource usage may occur, and silence is needed or transmission of CD-SSB of skip own cell may be skipped.

Illustratively, a base station that measures inter-base station channel CLI using CD-SSBs from neighboring cells may need to silence some of the CD-SSBs if the time and/or frequency resources of the CD-SSBs of the own cell and neighboring cells overlap.

Note that, since the base station cannot perform operations of receiving and transmitting signals at the same time in the case where the present cell reference signal and the neighboring cell reference signal resources overlap, in this case, the signal may not be transmitted or received on the corresponding resource, which may be referred to as a muted resource.

In some embodiments, if the own cell CD-SSB is muted, there are some effects on some procedures that operate based on the CD-SSB, such as initial access, cell search, and radio resource management (RRM, radio Resource Management) measurements.

Fig. 2 is an interactive schematic diagram illustrating an information indication method according to an embodiment of the present disclosure. As shown in fig. 2, embodiments of the present disclosure relate to an information indication method for a communication system 100, the method comprising:

step S2101: the network device determines first information.

In some embodiments, the first information is used to determine the second resource.

In some embodiments, the second resource is a resource for cross-link interference CLI measurement.

In some embodiments, the first information may be indication information.

In some embodiments, the first information indicates the second resource.

In some embodiments, the second resource may correspond to a time unit.

In some embodiments, the network device sends signaling to the terminal to silence (muting) CLI to measure the corresponding resources. Here, the signaling may be radio resource Control (RRC, radio Resource Control) signaling or medium access Control (MAC, media Access Control) Control Element (CE). It should be noted that the muted resource may be a resource where the base station or the terminal does not transmit or receive data on the corresponding resource.

In some embodiments, the muted UL resources are used to determine the second resources. The UL resources that are muted may be determined based on the CLI measured resources. For example, in order to reduce interference to CLI measurement, the terminal receives signaling sent by the base station to silence UL resources corresponding to CLI measurement, where the UL resources may be considered as resources of CLI measurement, i.e. second resources.

Note that, since the silenced uplink UL resource is essentially a resource that generates a resource conflict corresponding to the SSB transmission and the CLI measurement, the silenced uplink UL resource may be used to determine the second resource.

In some embodiments, the first information indicates a parameter associated with the second resource.

In some embodiments, the parameter indicated by the first information comprises at least one of:

a period of performing CLI measurements;

a slot offset;

index number of the symbol.

For example, the period of performing CLI measurement is 5 slots, the corresponding slot offset is 2 slots (the initial slot may be used as a reference for offset), if the corresponding slots in the time domain are slot0, slot1, slot2, slot3, slot4, slot5, slot6, slot7, slot8, slot9 and slot10 respectively, the starting slot for starting to perform CLI measurement for the first time may be slot2, and the starting slot for starting to perform CLI measurement for the second time may be slot7.

Illustratively, if slot2 includes 14 symbols, the corresponding index number may be 0-13, and if CLI measurement starts on the 3 rd symbol of slot2 and CLI measurement ends on the 6 th symbol, the index number of the symbol may be 2, 3, 4, 5. The time unit corresponding to the second resource indicated by the first information may be determined based on the index numbers 2, 3, 4, 5.

In some embodiments, the index number of the symbol may be the index number of the OFDM symbol.

In some embodiments, the located OFDM symbol index may be indicated based on a bitmap (bitmap) manner.

For example, the bitmap includes 14 bits, corresponding to 14 symbols respectively, and the bitmap values are "00111100000000" respectively, that is, the CLI measurement starts to be performed on the 3 rd symbol, and the CLI measurement ends to be performed on the 6 th symbol, and then the index number of the symbol may be the values corresponding to the 3 rd, 4 th, 5 th and 6 th bits of the bitmap.

In some embodiments, the OFDM symbol index may be indicated based on a starting symbol index and a number of persistent symbols.

Illustratively, the slot in which the CLI measurement is performed includes 14 symbols, and if the CLI measurement starts on the 3 rd symbol and ends on the 6 th symbol, the start symbol index may be 3 and the number of continuous symbols may be 4.

In some embodiments, the second resources comprise time domain resources and/or frequency domain resources.

Step S2102: the network device sends first information to the terminal.

In some embodiments, the terminal receives first information sent by the network device.

In some embodiments, the network device sends the first information to the terminal through RRC signaling.

In some embodiments, the network device transmits the first information to the terminal through the MAC CE.

In some embodiments, the network device transmits the first information to the terminal through downlink control information (DCI, downlink Control Information).

Step S2103: the terminal performs a first operation and/or the network device performs a second operation.

In some embodiments, there may be overlapping resources between a first resource for transmitting a downlink signal and a second resource for CLI measurement.

In some embodiments, the terminal determines a first operation for signaling in response to there being an overlapping resource between a first resource for transmitting a downlink signal and a second resource for cross-link interference, CLI, measurement.

In some embodiments, the terminal determines a first operation for signaling in response to there being an overlapping resource between a first resource for transmitting a downlink signal and a second resource for cross-link interference, CLI, measurement and the network device performing resource collision processing.

In some embodiments, the resource collision may be a collision of uplink and downlink transmissions in time units, e.g., if the network devices can only receive or transmit simultaneously (e.g., in a half duplex scenario), then the situation of uplink and downlink collisions may occur even if the resources do not overlap. At this time, it is necessary to perform the network device to perform collision processing, reducing the case where wireless communication is unreliable due to resource collision.

In some embodiments, the resource conflict may be a conflict of time-frequency resources, for example, because overlapping resources are used for transmitting the downlink signal and CLI measurement, which may result in a conflict of use of the resources. At this time, it is necessary to perform the network device to perform collision processing, reducing the case where wireless communication is unreliable due to resource collision.

In some embodiments, the first resource comprises a time domain resource and/or a frequency domain resource; the second resources include time domain resources and/or frequency domain resources.

In some embodiments, the existence of overlapping resources between the first resource and the second resource may be that the first resource and the second resource overlap in the time domain.

In some embodiments, the existence of overlapping resources between the first resource and the second resource may be that the first resource and the second resource exist overlapping both in the time domain and in the frequency domain.

In some embodiments, the existence of overlapping resources for the first resource and the second resource may be an intersection between the first resource and the second resource.

Here, the first resource is a resource for transmitting a downlink signal, and the second resource is a resource for cross link interference CLI measurement.

In some embodiments, the signal transmission includes downlink signal reception and/or uplink signal transmission.

In some embodiments, the downstream signal may be a synchronization signal block (SSB, synchronization Signal Block).

In some embodiments, the terminal does not expect to receive the downlink signal on the first resource in response to there being an overlapping resource between the first resource for transmitting the downlink signal and the second resource for cross-link interference CLI measurement and performing resource collision processing.

In some embodiments, in response to there being an overlapping resource between a first resource for transmitting a downlink signal and a second resource for cross-link interference, CLI, measurement and performing resource collision processing, the terminal determines whether to receive the downlink signal on the first resource based on a priority of the first behavior; wherein the first behavior comprises CLI measurements.

In some embodiments, the first behavior comprises at least one of:

CLI measurement (CLI measurement);

cell search (Cell search);

initial access (initial access);

beam measurement (beam measurement);

radio resource management (RRM, radio Resource Management) measurement (RRM measurement).

In some embodiments, the CLI-measurement is lower in priority than the cell search.

In some embodiments, CLI measurements have a lower priority than initial accesses.

In some embodiments, CLI measurements have a lower priority than cell search and initial access.

In some embodiments, CLI measurements have a higher priority than beam measurements.

In some embodiments, the CLI measurement is higher priority than the RRM measurement.

In some embodiments, CLI measurements have a higher priority than beam measurements and RRM measurements.

In some embodiments, the priority of the cell search or the priority of the initial access is higher than the priority of the CLI measurement, and the priority of the CLI measurement is higher than the priority of the beam measurement or RRM measurement.

In some embodiments, the priority of the cell search is higher than the priority of the initial access, the priority of the initial access is higher than the priority of the CLI measurement, the priority of the CLI measurement is higher than the priority of the beam measurement, and the priority of the beam measurement is higher than the priority of the RRM measurement.

As such, illustratively, when a resource conflict occurs between the RS for CLI measurement and the downlink signal for cell search, the terminal preferentially receives the downlink signal for cell search.

As such, the terminal preferentially receives the downlink signal for initial access, illustratively, when a resource collision occurs between the RS for CLI measurement and the downlink signal for initial access.

As such, the network device preferentially receives the RS for CLI measurement, illustratively, when a resource collision occurs between the RS for CLI measurement and the downlink signal for beam measurement.

As such, the network device preferentially receives RSs for CLI measurement, illustratively, when a resource conflict occurs between for CLI measurement and for RRM measurement.

In some embodiments, in response to there being an overlapping resource between a first resource for transmitting a downlink signal and a second resource for cross-link interference CLI measurement, and the network device performs resource collision processing and does not expect to receive the downlink signal on the first resource, the terminal does not expect to transmit an uplink signal. Here, performing the resource collision process may be an operation in which the network device performs not simultaneously receiving the overlapped resource transmission downlink signal and the CLI measurement. E.g. operation of transmission of CD-SSB of the mute or skip own cell. It should be noted that, the resource collision may be a collision between uplink transmission and downlink transmission in a time unit, for example, if the network device can only receive or transmit simultaneously (for example, in a half duplex scenario), then even if the resources do not overlap, an uplink collision and a downlink collision may occur. At this time, it is necessary to perform the network device to perform collision processing, reducing the case where wireless communication is unreliable due to resource collision. In addition, the resource conflict may be a conflict of time-frequency resources, for example, because overlapping resources are used for transmitting the downlink signal and CLI measurement, which may result in a conflict of use of the resources. At this time, it is necessary to perform the network device to perform collision processing, reducing the case where wireless communication is unreliable due to resource collision.

In some embodiments, in response to there being an overlapping resource between a first resource for transmitting a downlink signal and a second resource for cross-link interference CLI measurement, and the network device performs resource collision processing and does not expect to receive the downlink signal on the first resource, the terminal allows transmission of an uplink signal based on scheduling.

In some embodiments, the terminal obtains first information; wherein the first information is used to determine the second resource.

In some embodiments, the terminal determines the first information based on predefined information.

In some embodiments, the predefined information may be information predefined by a protocol, or may be information preconfigured by a user, where the predefined information may be stored in a predefined storage area of the terminal. The predefined information may be used to determine the second resource.

In some embodiments, the terminal determines the first information based on the muted UL resources.

In some embodiments, the terminal receives the first information sent by the network device through RRC signaling.

In some embodiments, in response to there being overlapping resources between the first resources for transmitting the downlink signal and the second resources for cross-link interference CLI measurement and performing resource collision processing, the network device determines a second operation for signal transmission.

In some embodiments, in response to there being an overlapping resource between a first resource for transmitting a downlink signal and a second resource for cross-link interference CLI measurement and the network device performing resource conflict processing, the network device determines a second operation for signal transmission.

In some embodiments, in response to there being an overlapping resource between a first resource for transmitting a downlink signal and a second resource for cross-link interference, CLI, measurement and performing resource conflict processing, the network device relinquishes the downlink signal transmission, the network device receives the CLI-RS, and the network device performs the CLI measurement.

In some embodiments, in response to there being an overlapping resource between a first resource for transmitting a downlink signal and a second resource for cross-link interference, CLI, measurement and performing resource collision processing, the network device determines whether to transmit the downlink signal on the first resource based on a priority of a first behavior; wherein the first behavior comprises CLI measurements.

Fig. 5a is an interactive schematic diagram illustrating an information indication method according to an embodiment of the present disclosure. As shown in fig. 5a, an embodiment of the present disclosure relates to an information indication method for a communication system 100, the method comprising one of the following steps:

Step S5101: the network device sends first information to the terminal.

In some embodiments, the first information indicates a second resource for CLI measurement; a first operation for signaling is determined in response to there being an overlapping resource between a first resource for transmitting a downlink signal and the second resource.

In some embodiments, the first information is used to indicate terminal capabilities of the terminal; the terminal capabilities include capabilities determined based on a cruising energy of the terminal.

Alternative implementations of step S5101 may refer to alternative implementations of step S2102 in fig. 2 and other relevant parts in the embodiment related to fig. 2, which are not described here again.

In some embodiments, the method may include the method of the embodiments of the communication system side, the terminal side, the network device side, and the like, which are not described herein.

In order to better understand the information indication method related to the embodiments of the present disclosure, the following further describes the technical solution of the present disclosure through 2 exemplary embodiments:

example 1:

in some embodiments, the terminal is a terminal supporting DTDD feature, and at a specific time unit (corresponding to the second resource in this disclosure), the base station receives the CLI-RS to make CLI measurement, and the process is transparent to the terminal.

In some embodiments, for example, on flexible symbols (flexible symbols), SSB (corresponding to downlink signals in the present disclosure) transmissions may collide with CLI measurements on time unit and/or frequency domain resources for interfered (victim) base stations (gNB). At this point, the interfered base station may give up transmitting SSB.

In some embodiments, the terminal does not expect to transmit uplink data nor is it expected to be signaled as UL in the time cell in which the SSB is located. If the base station gives up the transmission of the SSB, the terminal fails to receive the SSB, so that the success probability of the corresponding initial access or cell search is reduced, and the performance of RRM measurement is reduced.

In some embodiments, if the terminal cannot receive the SSB in the corresponding time unit, the base station will perform CLI measurement in the time unit, that is, the cell in which the base station is located is in uplink. At this time, in order to improve data transmission efficiency, the terminal may perform uplink data transmission.

In some embodiments, the terminal needs to know the time unit in which the CLI measurement is located to determine on which time-frequency domain resources to perform the CLI measurement, and the specific learning manner may include at least one of the following:

mode 1: the terminal receives the RRC signaling and determines the time unit in which the CLI measurement is based on the RRC signaling or based on a predefined mode. The RRC signaling or predefined manner may include one or more of the following parameters: the period, slot offset, and the OFDM symbol index where the OFDM symbol index is located, where the OFDM symbol index may be indicated based on a bitmap manner, or a starting symbol index and a continuous symbol number;

Mode 2: and the terminal receives the signaling and determines the resource where the UL multiplexing is located. And the terminal determines the resources as time units and/or frequency domain resources for the base station to perform CLI measurement.

For mode 2, the accuracy of the CLI measurement performed by the interfered base station is improved. Accordingly, the data of the uplink transmission of the terminal is dropped from the time-frequency domain resource where the CLI-RS is located. The mute resources are determined based on either a trans-parent (i.e., base station scheduling) or a non-trans-parent (i.e., signaling indication). If the mute resource is configured based on a non-transparent mode, the terminal may determine a time unit and/or a frequency domain resource of CLI measurement based on the signaling.

For example, the signaling may use DL rate matching configuration, that is: the number of periodic intervals slots and the slots in the period are configured, a specific orthogonal frequency division multiplexing (OFDM, orthogonal Frequency Division Multiplexing) symbol (symbol) in one slot is determined by a bitmap mode, and a Resource Block (RB) and/or a Resource Element (RE) in which a Resource is located is indicated by a bitmap mode.

The embodiment enables the terminal to determine the time unit and/or the frequency domain resource where the base station performs CLI measurement, so as to perform subsequent further operations.

Example 2:

in some embodiments, the terminal is a terminal supporting DTDD feature, and the base station receives CLI-RS to make CLI measurement at a specific time unit, the process being transparent to the terminal.

In some embodiments, on the flexible symbol, it may happen for the victim gNB that SSB transmissions collide with CLI measurements on time units and/or frequency domain resources. At this time, the victim gNB may discard the SSB, and the CLI measurement may discard.

In some embodiments, for the above conflict problem, the victim gNB may discard the SSB, possibly discard the CLI measurement, and the terminal may behave as follows:

behavior 1: consider that SSBs are transmitted in bursts (bursts), i.e., multiple SSBs may be transmitted. Accordingly, in the time unit and/or the frequency domain unit where the CLI is located, the victim gNB will discard the SSB transmission, and perform CLI measurement. Therefore, in the time unit where the CLI is located, the terminal does not expect to receive the corresponding SSB;

behavior 2: considering that SSB may be performed in different application scenarios, for example: cell search, initial access, beam measurement, RRM measurement, etc. Accordingly, the base station can define corresponding priorities according to different application scenarios, and decide whether to perform SSB transmission or CLI-RS reception to perform CLI measurement. Illustratively, considering that the cell search and initial access determine whether the terminal accesses the cell and whether subsequent data transmission is possible, one possible priority rule is as follows:

cell search or initial access > CLI measurement > beam or RRM measurement,

for example, if the SSB is used to perform a cell search procedure of a specific (or arbitrary terminal) terminal, the base station will discard CLI measurement and perform SSB transmission. Correspondingly, the terminal determines whether to receive the SSB based on the definition priority. Based on the above definition priority, if the terminal performs the cell search procedure, the terminal expects to receive the SSB for cell search on the time cell where the CLI is located and the time cell configured for SSB reception. If the terminal performs the RRM procedure, the terminal does not expect to receive SSB on the time unit where the CLI is located and configured to receive SSB, considering that the RRM has a lower priority than the CLI measurement.

In some embodiments, the terminal does not expect to transmit an uplink signal and does not expect to be configured as UL on a time unit configured to transmit SSB. Based on the above scheme, if the terminal does not expect to receive the SSB, the terminal may perform uplink data transmission to improve data transmission efficiency.

In some embodiments, the terminal is allowed to transmit uplink data based on the schedule on the condition that the terminal does not expect to receive SSB on the time unit where the CLI is located and on the time unit configured to receive SSB.

In some embodiments, the terminal is allowed to configure UL on the condition that the terminal does not expect to receive SSB on the time unit where CLI is located and on the time unit where SSB is configured to receive.

In some embodiments, for the present cell, a scenario (for example, flexible slot, SBFD slot) that there is an overlay at the SSB and CLI measurement time may determine the behavior of the terminal, so as to achieve consistent understanding between the base station and the terminal.

In the embodiments of the present disclosure, some or all of the steps and alternative implementations thereof may be arbitrarily combined with some or all of the steps in other embodiments, and may also be arbitrarily combined with alternative implementations of other embodiments.
