Description

Information indication method, terminal, network device, communication system and storage medium Technical Field

[0001] The present disclosure relates to the field of communication technologies, and in particular to an information indication method, a terminal, a network device, a communication system, and a storage medium. Background Art

[0002] In the field of communications technology, in dynamic time division duplex (DTDD) scenarios, to improve uplink communication performance, the proportion of uplink (UL) transmission time slots in the TDD configuration is increased accordingly. In this scenario, if adjacent cells still use the previous TDD structure, the transmission directions of the two cells will be inconsistent, causing serious interference.

[0003] Summary of the Invention

[0004] With the introduction of cross-link interference (CLI) measurement, communication mechanisms require adjustments. For example, indication signaling can be used to indicate the spatial relationship (e.g., QCL relationship) of the reference signals used for CLI measurement. Upon receiving the indication signaling, the terminal can determine the receive beam (i.e., Rx beam) used to receive the CLI reference signal and obtain the corresponding CLI levels for different Rx beams. Based on this CLI level, the Rx beam with a lower CLI level can be scheduled for signal transmission, thereby improving communication performance.

The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0187] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution provided by the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0188] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1a, or a portion thereof, but are not limited thereto. The entities shown in FIG1a are illustrative only. The communication system may include all or a portion of the entities shown in FIG1a, or may include other entities other than those shown in FIG1a. The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0189] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0190] In some embodiments, in dynamic time division duplex (DTDD) scenarios, to improve uplink communication performance, the proportion of uplink (UL) transmission time slots in the TDD configuration is increased accordingly. As shown in Figure 1b, if adjacent cells still use the previous TDD structure, the transmission directions of the two cells will be inconsistent, causing severe interference.

[0191] In some embodiments, to reduce cross-link interference (CLI), a victim terminal (victim) receives a CLI reference signal (CLI-RS) at a specific time to perform CLI measurement for subsequent further CLI mitigation operations.

[0192] In some embodiments, the SRS used for CLI measurement is not configured with an Rx beam (quasi co-location (QCL)). Since no Rx beam is configured, the CLI levels corresponding to different Rx beams cannot be obtained based on the Rx beams, providing a reference for subsequent base station scheduling. For example, the base station cannot schedule an Rx beam with a lower CLI for signal transmission. To improve base station scheduling flexibility and reduce the impact of CLI, it is considered to configure the corresponding Rx beam for CLI-SRS on a base station basis.

[0193] In some embodiments, for L1 or L2 CLI measurement, periodic, semi-periodic and aperiodic CLI-RSs provide a possibility for periodic, semi-periodic and aperiodic CLI measurement.

[0194] In some embodiments, based on periodic measurement reporting, since semi-periodic and aperiodic measurements can flexibly configure measurement reporting time based on activation signaling, measurement results corresponding to different time intervals can be obtained. In this way, semi-periodic and aperiodic measurement reporting are conducive to providing the base station with more flexible measurement results.

[0195] In some embodiments, to improve the flexibility of CLI measurement reporting, the QCL relationship can be dynamically configured for the CLI-RS. Compared with RRC signaling reconfiguration, this can reduce the latency of the QCL relationship and reduce signaling overhead.

[0196] In some embodiments, the QCL relationship can be dynamically indicated for the CLI-RS using indication signaling. Since the QCL relationship is dynamically configured and CLI measurements need to be performed based on the QCL relationship, the measurement results obtained by the CLI measurement also change based on the changes in the QCL relationship. This makes the reporting of measurement results more flexible.

[0197] In some embodiments, among the CLI reference signals used for CLI measurement, the cross-link interference sounding reference signal (CLI-SRS) can provide accurate reference signal received power (RSRP) measurement results. Due to the accurate measurement results, the CLI levels corresponding to different Rx beams can be accurately determined based on the Rx beam. Based on the CLI levels, an Rx beam with a lower CLI is scheduled for signal transmission, thereby utilizing further CLI suppression.

[0198] In some embodiments, the Cross-Link Interference Reference Signal (CLI-RS) does not support the configuration of QCL relationships and the update of corresponding RS signaling. However, for RSs in other application scenarios, such as antenna switching and beam management, their spatial relationships can be updated based on MAC CE signaling. Exemplarily, the spatial relationship can be configured based on RRC signaling and can be updated based on MAC CE. Here, the CLI-RS can be a CLI-SRS.

[0199] It should be noted that the CLI-RS in the present disclosure may include CLI-SRS. The example of CLI-SRS in the present disclosure is only used as an example for illustrative purposes and does not constitute a limitation of the present solution. In some embodiments, please refer to Figure 1c, which shows the media access control (MAC) control element (CE) structure and information unit (IE) corresponding to the first type of measurement. The analysis is as follows. It should be noted that after receiving the MAC CE, the terminal can determine the spatial relationship based on the MAC CE (it should be noted that in the related technology, the spatial relationship can be configured based on RRC signaling. However, if the corresponding spatial relationship is updated, it needs to be reconfigured through RRC signaling, and the corresponding time extension is extended. For this reason, a method of updating the spatial relationship using MAC CE signaling is introduced, which is conducive to reducing the update delay and improving data transmission efficiency), and performing the first type of measurement on the beam determined based on the spatial relationship:

[0200] A / D field: This field indicates whether to activate or deactivate the specified semi-persistent SRS (SP) resource set. Setting this field to "1" indicates activation, otherwise it indicates deactivation. If the indicated SRS resource set (ID, IDentifier) ​​is for an aperiodic SRS (Aperiodic SRS) resource set, the MAC entity shall ignore this field.

[0204] Supplementary Uplink (SUL) field: This field indicates whether the MAC CE applies to a Normal Uplink (NUL) carrier or a SUL carrier configuration. This field is set to "1" to indicate that it applies to a SUL carrier configuration, and is set to "0" to indicate that it applies to a NUL carrier configuration.

[0206] F i Field: This field indicates the resource type used as the spatial relationship of the SRS resources in the SP and AP SRS resource sets, which is indicated by the SP and AP SRS resource set ID fields. F0 represents the first SRS resource in the resource set, F1 represents the second resource, and so on. This field is set to "1" to indicate the use of the non-zero power channel state information reference signal (NZP CSI-RS, None Zero Channel State Information-Reference Signal) resource index, and is set to "0" to indicate the use of the synchronization signal block (SSB, Synchronization Signal and PBCH block) index or SRS resource index. The length of the field is 1 bit. This field exists only when the MAC CE is used to activate the SP SRS resource set (that is, the A / D field is set to 1) or the AP SRS resource set.

[0209] Resource IDi field: This field contains the identifier of the spatial relation-derived resource for SRS resource 1. Resource ID0 refers to the first SRS resource in the resource set, resource ID1 refers to the second SRS resource, and so on. If Fi is set to "0", the first bit of this field is always set to "0". If Fi is set to "0" and the second bit of this field is set to "1", the remainder of the field contains the SSB-Index. If Fi is set to "0" and the second bit of this field is set to "0", the remainder of the field contains the SRS-Resource Id. The length of this field is 8 bits. This field is present only when the MAC CE is used to activate the SP SRS resource set (i.e., the A / D field is set to 1) or the AP SRS resource set.

[0210] R field: reserved bit, set to 0.

[0211] In some embodiments, dynamic updating of the CLI-SRS QCL relationship is implemented, which helps the terminal measure different CLI information for different receiving beams, facilitates subsequent scheduling, and reduces the impact of CLI.

[0212] FIG2a is an interactive diagram of an information indication method according to an embodiment of the present disclosure. As shown in FIG2a, the embodiment of the present disclosure relates to an information indication method, which is used in a communication system 100 and includes:

[0213] Step S2101: The network device sends a first signaling to the terminal.

[0214] In some embodiments, the terminal receives first signaling sent by the network device.

[0215] In some embodiments, the terminal is an enhanced DTDD terminal.

[0216] In some embodiments, the first signaling is a MAC CE.

[0217] In some embodiments, the first signaling is used to indicate the spatial relationship of a reference signal (RS).

[0218] In some embodiments, a reference signal is used for CLI measurement.

[0219] In some embodiments, the reference signal is a sounding reference signal (SRS).

[0220] In some embodiments, the reference signal includes at least one of the following:

[0221] Periodic reference signal;

[0222] Half-cycle reference signal;

[0223] Aperiodic reference signal.

[0224] In some embodiments, the reference signal may be a cross-link interference reference signal (CLI-RS). Exemplarily, the CLI-RS may be a CLI-SRS.

[0225] In some embodiments, the SRS includes at least one of the following:

[0226] Periodic SRS;

[0227] Semi-persistent SRS;

[0228] Aperiodic SRS (Aperiodic SRS).

[0229] In some embodiments, the first signaling is used to determine the spatial relationship of a cross-link interference reference signal CLI-RS.

[0230] In some embodiments, the spatial relationship is used to update a corresponding quasi-co-sited QCL relationship.

[0231] In some embodiments, the first signaling indicates a QCL relationship.

[0232] In some embodiments, the first signaling indicates a QCL relationship for the SRS. In some embodiments, the terminal may determine a corresponding beam based on the QCL relationship. The beam may be a receive beam (Rx beam) or a transmit beam (Tx beam). Here, the receive beam may be used to receive a reference signal, and the transmit beam may be used to send a reference signal.

[0233] In some embodiments, the QCL relationship may be indicated by a Transmission Configuration Indicator (TCI).

[0234] In some embodiments, different TCI states (different values ​​of TCI) may correspond to QCL relationships of different reference signals, that is, to receive beams used to transmit different reference signals.

[0235] In some embodiments, the first signaling indicates a spatial relationship of at least one reference signal.

[0236] In some embodiments, the first signaling indicates a spatial relationship of at least one reference signal in the first set. For example, the second signaling may be used to configure an initial spatial relationship. After the second signaling is used to configure the spatial relationship, the first signaling may be used to update the spatial relationship. In this way, the spatial relationship may be dynamically updated. Here, the first signaling may be a MAC CE, and the second signaling may be a Radio Resource Control (RRC) signaling.

[0237] In some embodiments, the first signaling may indicate a spatial relationship of a CLI-RS or a reference signal of a first type of measurement.

[0238] In some embodiments, the terminal receives first information sent by the network device, and determines, based on the first information, that the first signaling is used to indicate a spatial relationship of a CLI-RS or a spatial relationship of a reference signal for a first type of measurement.

[0239] It should be noted that the first type of measurement may be measurements related to antenna switching, beam management, codebook, and non-codebook, but is not limited to the above measurements, and may also be other scenarios that need to be applied to reference signals. The reference signal (RS) corresponding to the first type of measurement may be an uplink transmission of the terminal. Exemplarily, in a beam management scenario, the terminal may send a reference signal to the base station; the base station may receive the reference signal through one of multiple beams according to the configured beam alignment; the base station determines whether to initiate beam switching based on the measured signal power (e.g., RSRP) of the received reference signal.

[0240] In some embodiments, the terminal determines, according to predefined information, that the first signaling is used to indicate a spatial relationship of a CLI-RS or a spatial relationship of a reference signal for a first type of measurement.

[0241] In some embodiments, the first signaling carries configuration information, the configuration information indicates at least one reference signal resource, and the spatial relationship is based on the reference signal resource configuration. Here, the configuration information can be indicated in a set form, for example, the configuration information indicates a first set.

[0242] In some embodiments, the configuration information is one of the following:

[0243] a reference signal set;

[0244] CLI resource list;

[0245] CLI resource configuration.

[0246] In some embodiments, the configuration information may be indicated in a set form, for example, the configuration information indicates a first set. The first set may include at least one reference signal, and the first signaling may indicate a reference signal resource corresponding to each reference signal in the first set. In some embodiments, the first set is at least one of the following:

[0247] a reference signal set;

[0248] CLI resource configuration;

[0249] List of CLI resources.

[0250] Exemplarily, the reference signal set may be an RS set. The RS set may be a CLI-RS set. For example, an SRS set may include at least one SRS resource. Each SRS resource may correspond to a resource index, which is used to uniquely represent an SRS resource.

[0251] Exemplarily, the CLI resource configuration may be CLI resource config.

[0252] In some embodiments, the CLI resource config defines a list of CLI-RS resources and / or a list of CLI-RS resource sets. Each resource set defines a collection of CLI-RS resources.

[0253] Exemplarily, the CLI resource list may be a CLI resource list.

[0254] In some embodiments, the CLI resource list may include at least one CLI-RS resource, and the CLI-RS resources at different positions in the list are different. A CLI-RS resource may be uniquely represented by its position in the list. Here, the CLI-RS may be a CLI-SRS.

[0255] Here, the SRS resources at different positions in the CLI resource list correspond to a position index corresponding to the position. The position index can be used to uniquely represent the SRS resource. For example, in the CLI resource list, based on the sequence of {1, 2, 3…, M}, it can be determined that the first number corresponds to position index 1 (or 0), and the second number corresponds to position index 2 (or 1), where 1 (or 0) corresponds to the SRS resource corresponding to the first position index, 2 (or 1) corresponds to the SRS resource corresponding to the second position index, and so on.

[0256] In some embodiments, the configuration information indicates a spatial relationship of the at least one reference signal based on a first order.

[0257] In some embodiments, the first sequence is one of the following:

[0258] The reference signal resource indexes corresponding to the reference signals are ordered from small to large;

[0259] The order of reference signal resource indexes corresponding to the reference signals from largest to smallest;

[0260] The position indexes corresponding to the reference signals are ordered from small to large;

[0261] The position indexes corresponding to the reference signals are in descending order.

[0262] In some embodiments, the first order is determined based on a predetermined rule, which may be a wireless communication rule.

[0263] In some embodiments, the spatial relationship of the at least one reference signal may be indicated based on an ascending order of reference signal resource indices corresponding to the reference signals.

[0264] In some embodiments, the spatial relationship of the at least one reference signal may be indicated based on a descending order of reference signal resource indices corresponding to the reference signals.

[0265] In some embodiments, the spatial relationship of the at least one reference signal can be indicated based on the position index of the reference signal in the first set in ascending order. Exemplarily, the first set is a CLI resource list, and the SRS resources at different positions in the CLI resource list correspond to a position index corresponding to the position, that is, the position index corresponding to the SRS resource can be determined according to the position of the SRS resource in the CLI resource list, so that the position index can uniquely represent the SRS resource. For example, in the CLI resource list, based on the sequence of{1,2,3…,M}, it can be determined that the first number corresponds to the position index 1 (or 0), and the second number corresponds to the position index 2 (or 1), wherein 1 (or 0) corresponds to the SRS resource corresponding to the first position index, 2 (or 1) corresponds to the SRS resource corresponding to the second position index, and so on.

[0266] In some embodiments, the spatial relationship of the at least one reference signal may be indicated based on a descending order of position indexes of the reference signal within the first set.

[0267] It should be noted that in this disclosure, resource index, resource identifier, and resource sequence number can be interchanged; location index, location identifier, and location sequence number can be interchanged; cell index, cell identifier, and cell sequence number can be interchanged; BWP index, BWP identifier, and BWP sequence number can be interchanged; and the index of the first set, the identifier of the first set, and the sequence number of the first combination can be interchanged. Here, interchange means that any one of them can be used in the corresponding embodiment.

[0268] In some embodiments, the first signaling includes at least one of the following:

[0269] A first information field, where the first information field is used to indicate a cell index corresponding to the configuration information;

[0270] A second information field, where the second information field is used to indicate a partial bandwidth BWP index corresponding to the configuration information;

[0271] The third information field is used to indicate the index of the reference signal set or CLI resource list corresponding to the configuration information.

[0272] Here, the configuration information may be indicated in a set format, for example, the configuration information indicates a first set. In some embodiments, the first signaling includes a first information field, where the first information field is used to indicate a cell index corresponding to the first set. Here, the first set may include at least one reference signal, and the first signaling may indicate a reference signal resource corresponding to each reference signal in the first set. Here, the reference signal may be a CLI SRS.

[0273] In some embodiments, the first signaling includes a second information field, where the second information field is used to indicate a BWP index of the partial bandwidth corresponding to the first set, or a BWP index corresponding to the first signaling application.

[0274] In some embodiments, the first signaling includes a third information field, where the third information field is used to indicate an index of the first set.

[0275] In this way, since the first signaling indicates the cell index, BWP index and index of the first set corresponding to the first set, the terminal can accurately determine the cell, BWP and first set to which the first signaling is applied based on the above index information after receiving the first signaling.

[0276] In some embodiments, the first signaling includes a fourth information field, and the value of the fourth information field is used to indicate that the first signaling is used for CLI measurement or for first type measurement. Here, since the existing mechanism only has signaling indications corresponding to the first type of measurement, if CLI measurement is introduced, in the signaling structure scenario that reuses the existing signaling, a determination mechanism is required to enable the terminal to determine whether the received signaling is for the first type of measurement (the indicated spatial relationship needs to be used to determine the Tx beam for signal reception) or for CLI measurement (the indicated spatial relationship needs to be used to determine the Rx Beam for signal transmission). In this way, the value of the fourth information field can be used to indicate whether the signaling is used for CLI measurement or for the first type of measurement.

[0277] In some embodiments, the fourth information field may include at least one bit, which may be a reserved bit in the multiplexing diagram 1c. Exemplarily, the bit is 1. When the bit value is "1", it may indicate that the first signaling is used for CLI measurement. When the bit value is "0", it may indicate that the first signaling is used for the first type of measurement. It should be noted that when the bit value is "1", the first signaling is used to indicate the spatial relationship of the CLI-SRS. When the bit value is "1", the first signaling is used to indicate the spatial relationship of the SRS used for the first type of measurement.

[0278] It should be noted that the first type of measurement may be measurements related to antenna switching, beam management, codebook, and non-codebook, but is not limited to the above measurements, and may also be other scenarios that need to be applied to reference signals. The reference signal (RS) corresponding to the first type of measurement may be an uplink transmission of the terminal. Exemplarily, in a beam management scenario, the terminal may send a reference signal to the base station; the base station may receive the reference signal through one of multiple beams according to the configured beam alignment; the base station determines whether to initiate beam switching based on the measured signal power (e.g., RSRP) of the received reference signal.

[0279] In some embodiments, a network device sends a second signaling to a terminal, the second signaling configuring an airspace relationship. After configuring the airspace relationship using the second signaling, the network device sends a first signaling to the terminal for updating the airspace relationship. In this way, the airspace relationship can be dynamically updated. Here, the first signaling can be a MAC CE, and the second signaling can be an RRC signaling.

[0280] In some embodiments, the terminal receives second information sent by the network device, and the terminal determines, based on the second information, that the first signaling is used to indicate a spatial relationship of a CLI-RS or a spatial relationship of a reference signal for first type measurement.

[0281] In some embodiments, the first signaling is determined to indicate the spatial relationship of the CLI-RS or the spatial relationship of the reference signal for the first type of measurement based on predefined information. In some embodiments, the terminal determines, based on the predefined information, that the first signaling is used to indicate the spatial relationship of the reference signal, and the reference signal is used for CLI measurement or for the first type of measurement. Here, the predefined information may be user-configured information. For example, the user-configured spatial relationship may be stored in a storage area of ​​the terminal. After obtaining the first signaling, the terminal directly obtains the spatial relationship from the storage area. The predefined information may also be spatial relationship information generated by the terminal, which is not limited here.

[0282] In some embodiments, the predefined information may also be information about a communication rule. The communication rule may be: For example, distinguishing between first-type measurements and CLI measurements based on a resource index. For example, if the resource index belongs to the first set, the corresponding resource is used for the first-type measurement. Otherwise, or if the resource index belongs to the second set, the corresponding resource is used for CLI measurement. For example, when the terminal receives a MAC CE, it indicates the resource index of the application. The terminal can distinguish the measurement type based on the resource index. The resource index may be at least one of a BWP index, a cell index, a resource set index, and a resource index.

[0283] Step S2102: The terminal performs a predetermined operation.

[0284] In some embodiments, the terminal determines the spatial relationship of a cross-link interference reference signal CLI-RS according to the first signaling.

[0285] In some embodiments, the terminal updates the corresponding quasi-co-site QCL relationship according to the spatial relationship.

[0286] In some embodiments, in response to determining that the first signaling indicates a spatial relationship of the reference signals for CLI measurement, the reference signals are received based on the spatial relationship.

[0287] In some embodiments, in response to determining that the first signaling indicates a spatial relationship of the reference signals for the first type of measurement, the reference signals are sent based on the spatial relationship.

[0288] In some embodiments, a corresponding beam, for example, an Rx beam or a Tx beam, may be determined based on the QCL relationship determined based on the spatial relationship.

[0289] In some embodiments, the spatial relationship may be indicated by TCI.

[0290] In some embodiments, different TCI states (different TCI values) may correspond to spatial relationships of different reference signals, that is, to Rx beams or Tx beams used to transmit different reference signals.

[0291] In some embodiments, the terminal receives second signaling; wherein the second signaling carries information of the initially configured airspace relationship.

[0292] Here, the second signaling can be RRC signaling, the first signaling can be MAC CE signaling, and the second signaling can be sent before the first signaling. In this way, the second signaling can indicate the configuration of the initial QCL relationship, the first signaling can indicate the updated QCL relationship, and the first signaling can update the initial QCL relationship to achieve dynamic update.

[0293] In some embodiments, based on predefined information, determining that the first signaling is used to indicate a spatial relationship of a reference signal used for CLI measurement. The terminal determines that the first signaling indicates a spatial relationship of a reference signal used for CLI measurement.

[0294] In some embodiments, based on predefined information, determining that the first signaling is used to indicate a spatial relationship of reference signals used for first type measurement. The terminal determines that the first signaling indicates a spatial relationship of reference signals used for first type measurement.

[0295] In some embodiments, a terminal receives first signaling, the first signaling includes a fourth information field, and a value of the fourth information field is used to indicate that the first signaling is used for CLI measurement. The terminal determines a spatial relationship of a reference signal indicated by the first signaling for CLI measurement.

[0296] In some embodiments, a terminal receives first signaling, the first signaling including a fourth information field, the value of the fourth information field being used to indicate that the first signaling is used for a first type of measurement, and the terminal determines a spatial relationship of a reference signal indicated by the first signaling for the first type of measurement.

[0297] For example, referring to Figure 1c, an information field indicating whether the first signaling is used for CLI measurement or for the first type of measurement can be set in a reserved bit position of the MAC CE structure shown in Figure 1c, for example, the first "R" or second "R" field of Oct2. When the value of "R" is 0, the first signaling is used for CLI measurement; when the value of "R" is 1, the first signaling is used for the first type of measurement. Referring to Figure 1c, the MAC CE structure also shows the cell ID, BWP ID, and set ID corresponding to the first set.

[0298] In some embodiments, the term "information" can be interchangeable with terms such as "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "field", and "data".

[0299] In some embodiments, the term "send" can be interchanged with terms such as "transmit", "report", and "transmit".

[0310] Step S3201: Receive first signaling.

[0311] In some embodiments, the first signaling is used to determine a spatial relationship of a cross-link interference reference signal CLI-RS; the spatial relationship is used to update a corresponding quasi-co-site QCL relationship.

[0387] Figure 5a is an interactive diagram of an information indication method according to an embodiment of the present disclosure. As shown in Figure 5a, the present disclosure embodiment relates to an information indication method, which is used in a communication system 100 and includes one of the following steps:

[0388] Step S5101: The network device sends a first signaling to the terminal.

[0389] In some embodiments, the first signaling is used by the terminal to determine the spatial relationship of the CLI-RS; the spatial relationship is used by the terminal to update the corresponding quasi-co-site QCL relationship.

[0390] The optional implementation of step S5101 can refer to the optional implementation of step S2101 in Figure 2a and other related parts of the embodiment involved in Figure 2a, which will not be repeated here.

[0391] In some embodiments, the above method may include the methods of the above-mentioned communication system side, terminal side, network device side, etc. embodiments, which will not be repeated here.

[0392] In order to better understand the embodiments of the present disclosure, the technical solution of the present disclosure is further described below through an exemplary embodiment:

[0393] In some embodiments, the terminal is a terminal supporting the DTDD feature. In a specific time unit, the terminal receives a CLI-RS to perform CLI measurement and reports a corresponding measurement result based on a configuration.

[0394] In some embodiments, for CLI measurements between L1 or L2 terminals, a QCL configuration is introduced for the corresponding CLI-RS to indicate the corresponding Rx receive beam. This facilitates obtaining the corresponding CLI levels for different Rx beams, providing a reference for subsequent base station scheduling. For example, the base station may schedule the Rx beam corresponding to the lower CLI for Physical Downlink Shared Channel (PDSCH) reception.

[0395] In some embodiments, on the basis of configuring the QCL relationship (corresponding to the spatial relationship in the present disclosure), MAC CE is introduced to update the corresponding QCL relationship. Taking into account that the update of the QCL of other SRSs in addition to CLI has been introduced in the relevant mechanism, the update is performed based on the SP or AP SRS spatial relationship indication MAC CE. Here, updating the QCL relationship can be understood as dynamically indicating the QCL relationship, that is, the network device can dynamically send the first signaling in the present disclosure (for example, MAC CE) to the terminal. It should be noted that if the QCL relationship is updated by RRC signaling reconfiguration, the delay of the QCL update will be longer due to the large delay. Therefore, using MAC CE to update the QCL relationship can reduce the delay compared to using RRC signaling reconfiguration to update the QCL relationship.

[0396] In one embodiment, referring to FIG6a, MAC CE signaling (which may be the signaling shown in FIG1c) is multiplexed, and the enhanced DTDD terminal receives the MAC CE signaling and determines the QCL relationship (or TCI state, or associated reference signal) corresponding to the corresponding RS resource identifier (ID). If the RS corresponding to the RS resource identifier is used for CLI measurement, the terminal receives the CLI-RS corresponding to the resource identifier based on the corresponding QCL relationship. The RS includes at least one of the following: a periodic reference signal (Periodic RS); a semi-persistent reference signal (Semi-persistent RS); or an aperiodic reference signal (Aperiodic RS).

[0397] In some embodiments, the multiplexed MAC CE signaling may use a MAC CE with the same identifier as an existing MAC CE. For example, the multiplexed MAC CE signaling may use existing MAC CE signaling. It is understood that if enhancements are made based on the multiplexed MAC CE, terminals supporting new features (e.g., supporting the DTDD feature) and standard terminals (e.g., legacy terminals) may interpret the information field of the MAC CE differently.

[0398] It should be noted that the CLI-RS in the present disclosure may include CLI-SRS, that is, CLI-SRS is a subordinate of CLI-RS. The example of CLI-SRS in the present disclosure is only used as an example for illustrative purposes and does not constitute a limitation to this solution.

[0399] In some embodiments, if the SRS corresponding to the SRS resource identifier is used for channel measurement (for example, antenna switching measurement, beam management measurement, codebook measurement, non-codebook measurement), the terminal sends the SRS corresponding to the resource identifier based on the QCL relationship, and the SRS includes at least one of the following: Semi-persistent SRS; Aperiodic SRS.

[0400] In some embodiments, enhanced MAC CE signaling is introduced. Based on the MAC CE shown in FIG6a , the enhanced MAC CE multiplexes a reserved bit (e.g., R) to indicate whether the MAC CE is used to indicate the spatial relationship of the CLI-SRS or the spatial relationship of other SRSs. Exemplarily, if the corresponding bit indicates "1," the MAC CE is used to indicate the spatial relationship of the CLI-SRS. If the corresponding bit indicates "0," the MAC CE is used to indicate the spatial relationship of other SRSs (e.g., antenna switching measurement, beam management measurement, codebook measurement, non-codebook measurement).

[0401] In some embodiments, the identifier corresponding to the enhanced MAC CE signaling may be different from the existing MAC CE, and the terminal may determine different MAC CEs based on different MAC CE identifiers.

[0402] In some embodiments, the enhanced MAC CE signaling may be MAC CE signaling that modifies, supplements, or adds to the function or indicated information of the information field of the existing MAC CE signaling.

[0403] In some embodiments, the multiplexed pre-bit (for example, R) can be the first R on the left corresponding to Oct 2, or the second R on the left corresponding to Oct 2, or the R corresponding to other Octs, which is not limited here.

[0404] In some embodiments, referring to FIG. 6 b , taking the multiplexing bit R corresponding to Oct 1 as an example, the multiplexing bit is exemplarily defined as S, and the corresponding signaling design and description are as follows:

[0405] S field: This field indicates whether the MAC CE is applied to CLI-SRS for CLI measurement or to SRS for other purposes. For CLI SRS-RSRP measurement, it is represented as "1". Otherwise, it is represented as "0";

[0406] R field: reserved bit, set to "0".

[0407] In some embodiments, if a MAC CE is used for CLI measurement, and the CLI-RS corresponding to the CLI measurement is configured based on a first set; exemplarily, the first set is an SRS set; and / or the first set is a CLI resource configuration; and / or the first set is a CLI resource list, which is not limited herein. The MAC CE indicates the corresponding first set identifier. Correspondingly, Fi corresponds to the (i+1)th CLI-SRS resource in the first set, and the SRS resource identifier is based on a one-to-one correspondence from small to large or from large to small.

[0408] In some embodiments, when the first set is a CLI resource configuration, the reference signals may be arranged based on the order of position indexes in the first set from small to large or the order of position indexes in the first set from large to small.

[0409] In some embodiments, the MAC CE is used for CLI measurement, and the CLI-RS corresponding to the CLI measurement is not based on a set configuration. Correspondingly, Fi corresponds to the (i+1)th CLI-SRS resource, and the SRS resource identifier is based on a one-to-one correspondence from small to large or from large to small.

[0410] In some embodiments, the reference signals may be arranged in ascending order based on their position indexes or in descending order based on their position indexes within the first set. In some embodiments, taking the above-mentioned CLI resource configuration as an example, refer to Figure 6c, where the corresponding first set is the CLI resource configuration. Figure 6c is a schematic diagram of the information field of an enhanced MAC CE, which indicates the spatial relationship of at least one reference signal based on the position indexes of the reference signals within the first set in ascending order. After receiving the enhanced MAC CE, the terminal may determine the spatial relationship and determine the beam based on the spatial relationship. Exemplarily, the corresponding information element (IE) has the following meanings:

[0411] CLI-SRS Resource Configuration Cell ID Field: This field indicates the identity of the serving cell that contains the indicated P, SP, or AP SRS resource set. If the C field is set to "0," this field also indicates the identity of the serving cell that contains all resources indicated by the Resource IDi field. The field can be 5 bits long.

[0412] BWP ID field for CLI-SRS resource configuration: This field indicates the UL BWP as the codepoint of the DCI Bandwidth Part Indicator field, which contains the indicated P or SP or AP CLI resource configuration. If the C field is set to "0", this field also indicates the identity of the BWP that contains all resources indicated by the Resource IDi field. The field length can be 2 bits.

[0413] CLI-SRS Resource Configuration ID field: This field indicates the P, SP and / or AP SRS resource set ID identified by SRS-ResourceSetId. The field length can be 4 bits.

[0414] F i Field: This field indicates the resource type used as the spatial relationship for the SRS resource in the P, SP, or AP CLI-SRS resource configuration, as indicated by the P / SP / AP CLI-SRS Resource Configuration ID field. F0 represents the first SRS resource in the resource configuration, F1 represents the second resource, and so on. Setting this field to "1" indicates the use of NZP CSI-RS resource indexing, while setting it to "0" indicates the use of SSB indexing or SRS resource indexing. The field length is 1 bit. This field is present only when the MAC CE is used to activate the SP SRS resource set (i.e., the A or D field is set to 1) or for the P or AP SRS resource set.
