However, this is not the only possibility.

[0090] In some embodiments, a core network device may be a single device comprising one or more network elements, or it may be multiple devices or a group of devices, each comprising all or part of the aforementioned one or more network elements. Network elements 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), or a Next Generation Core (NGC).

[0091] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0092] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. ​​The number and form of each main body are arbitrary.

[0093] The embodiments disclosed herein 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), 6th generation mobile communication system (6G), 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), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a 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, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0094] It is understood that the embodiments of this disclosure are introduced and described using the scenario of "using beam-based transmission and reception in a new air interface" as an example, but the solutions of each embodiment can be applied to other beam-related scenarios, and this disclosure does not limit them.

[0095] Regarding beam measurement reports, the current considerations are whether the base station is configured with periodic, semi-persistent, or non-periodic beam measurement reports.

[0096] However, changes in beam quality are actually the most timely information that terminals can detect. The length of the reporting period configured by the base station, or the timing of non-periodic reporting, may not be optimal. For example, with a period too short, the optimal K beams might be the same in two reports, resulting in minimal variation and wasted signaling; if too long, beam changes might occur before the reporting time, impacting communication quality. Similarly, with non-periodic reporting, the base station might trigger terminal reporting too early or too late, which is not the most suitable timing.

[0097] In some embodiments, an event-triggered beam reporting is proposed for a single TRP scenario, wherein the event includes at least one of the following:

[0098] Event 1: The beam quality (L1-RSRP / L1-SINR) of the current beam is below the threshold.

[0099] Event 2: The new beam's beam quality is one threshold higher than the current beam's beam quality.

[0100] The reference signal resource corresponding to the current beam for beam quality measurement is the synchronization signal block (SSB) resource of the CSI-RS or the QCL source of the CSI-RS, which is indicated by Type D of the quasi-co-location (QCL) in the indicated Transmission Configuration Indicator state (TCI state) or the activated Transmission Configuration Indicator state (TCI state). The new beam is the reference signal resource in the set of reference signal resources explicitly configured by the base station.

[0101] In a Multiple Transmission and Receiving Point (MTRP) scenario, where a cell contains multiple TRPs, there are two types of MTRPs. S-DCI-based MTRP involves one codepoint of a single downlink control information (S-DCI) that corresponds to two Transmission Configuration Indicator (TCI) states, each for a different TRP. However, different control resource sets (CORESETs) are not configured with different CORESETPoolIndexes. In M-DCI-based MTRP, different CORESETs are configured with different CORESETPoolIndexes, corresponding to different TRPs. Furthermore, each TRP's DCI only indicates the TCI state corresponding to its own TRP transmission; that is, each TRP can only schedule its own transmission.

[0102] In the MTRP scenario, the terminal may be simultaneously indicated with multiple indicated TCI states or multiple activated TCI states. Therefore, how to configure the reference signal resource set (RS set) for the new beam, and how to indicate the indicated TCI state / activated TCI state corresponding to each new beam RS set, are problems that need to be solved.

[0103] Therefore, this disclosure provides a communication method in which a terminal receives first information, the first information including a first set of reference signal resources, and indicates second information corresponding to the first set of reference signal resources. Based on the second information, a second set of reference signal resources can be determined. The second set of reference signal resources and the first set of reference signal resources in the first set of reference signal resources can be used to trigger a report, thereby enabling the terminal to determine the second information corresponding to the first set of reference signal resources while receiving the first set of reference signal resources. This facilitates the terminal's accurate handling of the correspondence between the reference signal resource set and different TRPs in MTRP scenarios, improving communication efficiency.

[0104] Figure 2 is a schematic diagram of a communication method interaction according to an embodiment of the present disclosure. As shown in Figure 2, this embodiment of the present disclosure relates to a communication method for a communication system 100, the method including:

[0105] In step S2101, network device 102 sends first information to terminal 101.

[0106] In some embodiments, terminal 101 receives first information sent by network device 102.

[0107] In some embodiments, "acquire," "get," "obtain," "receive," "transmit," "bidirectional transmission," and "send and / or receive" can be used interchangeably and can be interpreted as receiving from other entities, acquiring from protocols, acquiring from higher layers, obtaining through self-processing, or autonomous implementation. Protocols include, for example, at least one of the 3GPP protocol, Wi-Fi protocol, and audio and / or video protocols.

[0108] In some embodiments, terms such as “send,” “transmit,” “report,” “distribute,” “transmit,” “bidirectional transmission,” “send and / or receive” can be used interchangeably.

[0109] In some embodiments, the names of information, etc., are not limited to the names described in the embodiments. Terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0110] In some embodiments, the name of the first information is not limited, and it may be, for example, "configuration information".

[0111] In some embodiments, the first information includes a first set of reference signal resources, and the first information is used to determine the second information corresponding to the first set of reference signal resources. The second information can be used by the terminal to determine a second reference signal resource. The first set of reference signal resources includes at least one first reference signal resource, and at least one of the first and second reference signal resources can be used to trigger a report.

[0112] In some embodiments, the first information is used to determine the second information corresponding to the first reference signal resource set, including: the first information explicitly indicating the correspondence between the first reference signal resource set and the second information; or, the first information includes at least two information fields, different first reference signal resource sets are contained in different information fields, and different information fields correspond to different second information.

[0113] Optionally, the first information may explicitly indicate the correspondence between the first reference signal resource set and the second information. For example, the first information may indicate that the first reference signal resource set A corresponds to the second information 1, and the first reference signal resource set B corresponds to the second information 2, so that the terminal can determine the second information corresponding to the first reference signal resource set in the first information according to the correspondence indicated by the first information.

[0114] Optionally, the first information may include at least two information fields, with different first reference signal resources contained in different information fields, and different information fields corresponding to different second information. The inclusion of different sets of first reference signal resources in different information fields can also be understood as the network device indicating different sets of first reference signal resources through different information fields. The correspondence between different information fields and different second information can be, for example, through network device configuration of the correspondence between information fields and second information, predefined correspondence, or a protocol specifying the correspondence. For instance, assuming information field 1 corresponds to second information 1 and information field 2 corresponds to second information 2, the network device may include a first reference signal resource set A in information field 1. Then, the terminal can determine that the first reference signal resource set A corresponds to second information 1 based on the fact that the first reference signal resource set A is included in information field 1. Similarly, the network device may include a first reference signal resource set B in information field 2. Then, the terminal can determine that the first reference signal resource set B corresponds to second information 2 based on the fact that the first reference signal resource set B is included in information field 2. The examples given in this disclosure are exemplary and not limiting. This alternative can also be understood as implicitly indicating the correspondence between the first reference signal resource set and the second information.

[0115] In some embodiments, the first reference signal resource may correspond to a new beam, and the second reference signal resource may correspond to the current beam. For example, the set of first reference signal resources includes at least one first reference signal resource. Measuring the reference signal on the first reference signal resource yields a measurement result that characterizes the beam quality of the new beam. Measuring the reference signal on the second reference signal resource yields a measurement result that characterizes the beam quality of the current beam. For example, the measurement result may include Layer 1 reference signal received power (L1-RSRP), Layer 1 signal to interference plus noise ratio (L1-SINR), etc., but is not limited to these. At least one of the beam quality of the current beam and the beam quality of the new beam can be used to evaluate an event. For example, if the measurement result of the second reference signal resource is below a threshold (assumed to be threshold 1), it can be understood that the beam quality of the current beam is below threshold 1, thus satisfying Event 1 in the above embodiments, and triggering a report. For example, if the measurement result of the first reference signal resource is higher than the measurement result of the second reference signal resource by a threshold value (let's assume threshold value 2), it can be understood that the measurement result of the first reference signal resource is greater than the measurement result of the second reference signal resource, and the difference between the two is greater than threshold value 2. That is, the beam quality of the new beam is higher than the beam quality of the current beam by threshold value 2, which satisfies Event 2 in the above embodiment and can trigger a report. It is understood that the event is not limited to the examples Event 1 and Event 2. For example, if the measurement result of the first reference signal resource is higher than a threshold value (let's assume threshold value 3), that is, the beam quality of the new beam is higher than the threshold value, a report can also be triggered. This disclosure is not limited to this. The magnitude of threshold values ​​1, 2, and 3 is not limited in this disclosure.

[0116] In some embodiments, the report may be a beam report, a CSI report, or other types of report, which are not limited in this disclosure.

[0117] In some embodiments, the report includes at least one of a reference signal resource identifier and L1-RSRP / L1-SINR. The reference signal resource identifier may be, for example, the identifier of the reference signal resource that triggered the report, or, for example, the identifier of the reference signal resource corresponding to one or more best beams, or the identifier of the reference signal resource corresponding to one or more worst beams. The best beam may be the beam with the highest beam quality, which can be characterized by the measurement results of the reference signal resource corresponding to the beam; that is, the higher the measurement result of the reference signal resource, the higher the beam quality of its corresponding beam. Correspondingly, the worst beam may be the beam with the lowest beam quality. The reference signal resource identifier may be an SSB ID or a CSI-RS ID.

[0118] In some embodiments, the number of first reference signal resource sets can be one or more.

[0119] In some embodiments, in an MTRP scenario, each TRP can correspond to a current beam and a new beam, that is, each TRP can correspond to a first reference signal resource set and a second reference signal resource. A report corresponding to that TRP can be triggered if at least one of the measurement results of the first reference signal resource (i.e., the beam quality of the current beam) and the measurement results of the second reference signal resource (i.e., the beam quality of the new beam) is satisfied. The first information may include multiple first reference signal resource sets. However, determining the correspondence between multiple first reference signal resource sets and multiple TRPs, i.e., determining the correspondence between multiple first reference signal resource sets and multiple second reference signal resources, is a problem that needs to be solved. Therefore, the network device indicates the second information corresponding to the first reference signal resource set through the first information, so that the terminal can determine the second reference signal resource corresponding to the first reference signal resource set based on the second information. The second reference signal resource is the reference signal resource corresponding to the current beam of a certain TRP. Determining the second reference signal resource means determining the TRP corresponding to the first reference signal resource set.

[0120] In step S2102, terminal 101 determines the second reference signal resource based on the second information.

[0121] In some embodiments, the terminal may determine the second reference signal resource based on the second information.

[0122] In some embodiments, the second information includes at least one of the following: the sequence number of the first TCI state; and the index of the control resource set pool.

[0123] Optionally, the second information is the sequence number of the first TCI state. The terminal can determine the first TCI state based on the sequence number of the first TCI state, thereby determining the reference signal resource corresponding to the first TCI state as the second reference signal resource. For example, before receiving the first information, the terminal may have received other information. Based on this other information, it can determine the TCI state identifier (IDentity, ID) corresponding to multiple first TCI states and the sequence number of each first TCI state among the multiple first TCI states. If the sequence number of the first TCI stage in the first information is the same as the sequence number of the first TCI state contained in other information, the terminal can determine the TCI state ID corresponding to the first TCI state based on the sequence number of the first TCI state, and further determine that the second reference signal resource can be the same as the reference signal resource indicated by the TCI state ID. The reference signal resource indicated by the TCI state ID can be the CSI-RS resource corresponding to QCL Type D indicated by the TCI state ID or the SSB resource of the QCL source of the CSI-RS resource. The terminal determines the first TCI state based on its sequence number by obtaining the sequence number corresponding to each first TCI state through third information. This allows the terminal to determine the first TCI state corresponding to the sequence number when it receives first information containing such sequence numbers. The third information indicates the sequence number corresponding to each first TCI state. Each first TCI state can be a first TCI state configured by RRC or a first TCI state activated by the third information. Further explanation of the third information can be found in the embodiments of step S2103 below.

[0124] For example, when the second information is an index of a control resource pool, the sequence number of the first TCI state corresponding to the control resource pool can be determined based on the index. The subsequent process is similar to that when the second information is the sequence number of the first TCI state, and will not be elaborated upon here. For example, when the second information is an index of a control resource pool, third information containing the index of the control resource pool can be determined based on the index, and the second reference signal resource can be determined based on the first TCI state activated by the third information. For example, the reference signal resource corresponding to the first TCI state activated by the third information is determined as the second reference signal resource. The above examples in this disclosure are merely illustrative and are not limited thereto. For a related explanation of the third information, please refer to the various embodiments of step S2103 below.

[0125] In some embodiments, the first TCI state refers to the TCI state corresponding to the first reference signal resource set. The term "first" is used to distinguish it from other TCI states, and this disclosure does not limit the name. The sequence number of the first TCI state can be, for example, "first", "second", etc.

[0126] In some embodiments, the index of the control resource set pool can correspond one-to-one with the sequence number of the first TCI state. For example, if the index of the control resource set pool is "0", the sequence number of the first TCI state is "first"; if the index of the control resource set pool is "1", the sequence number of the first TCI state is "second". The index of the control resource set pool can also correspond one-to-one with the first TCI state. For example, if a third piece of information contains an index 0 of the control resource set pool, and a codepoint in the TCI indicator field of the third information activating the DCI corresponds to a first TCI state #1, then the index 0 of the control resource set pool corresponds to the first TCI state #1. If another piece of third information contains an index 1 of the control resource set pool, and a codepoint in the TCI indicator field of the third information activating the DCI corresponds to a first TCI state #2, then the index 1 of the control resource set pool corresponds to the first TCI state #2. For a more detailed explanation of the third information, please refer to the embodiments of step S2103 below.

[0127] In some embodiments, the first information is used to determine the second information corresponding to the first reference signal resource set. This first information may include at least two information fields, with different information fields corresponding to different second information. For example, if the second information is the TCI state or the index of the control resource set pool (CORESETPoolIndex), the following explanation is provided:

[0128] Optionally, the first information includes a first information field and a second information field. The first information field is used to indicate a first set of first reference signal resources, and the second information field is used to indicate a second set of first reference signal resources. The first information field and the second information field have a one-to-one correspondence with the first first TCI state and the second first TCI state. For example, the first information field corresponds to the first first TCI state, that is, the first set of first reference signal resources corresponds to the first first TCI state; the second information field corresponds to the second first TCI state, that is, the second set of first reference signal resources corresponds to the second first TCI state.

[0129] Optionally, the first information includes a first information field and a second information field. The first information field is used to indicate the first first reference signal resource set, and the second information field is used to indicate the second first reference signal resource set. The first and second information fields have a one-to-one correspondence with CORESETPoolIndex 0 and CORESETPoolIndex 1. For example, the first information field corresponds to CORESETPoolIndex 0, that is, the first first reference signal resource set corresponds to the first TCI state corresponding to CORESETPoolIndex 0; the second information field corresponds to CORESETPoolIndex 1, that is, the second first reference signal resource set corresponds to the first TCI state corresponding to CORESETPoolIndex 1.

[0130] In some embodiments, the first TCI state includes at least one of the following: an indicated first TCI state, which includes an indicated joint first TCI state or an indicated downlink first TCI state; and an activated first TCI state, which includes an activated joint first TCI state or an activated downlink first TCI state.

[0131] In some embodiments, the first TCI state includes an indicated first TCI state, which may also be referred to as a first indicated TCI state. The first indicated TCI state includes an indicated joint first TCI state or a downlink first TCI state.

[0132] In some embodiments, the first indicated TCI state includes two indication methods. One method involves RRC signaling configuration and MAC CE activation, where the RRC signaling configures a TCI state list, and the MAC CE activates one or more first indicated TCI states corresponding to a codepoint in the TCI field of the DCI. In this case, the one or more first indicated TCI states activated by the MAC CE serve as the terminal's first indicated TCI state. The other method involves RRC signaling configuration, MAC CE activation, and DCI indication, where the RRC signaling configures a TCI state list, and each codepoint in the multiple codepoints corresponding to the TCI field of the MAC CE activated DCI corresponds to one or more first indicated TCI states. The DCI indicates one codepoint among the multiple codepoints corresponding to the TCI field, and the one or more TCI states corresponding to the codepoint in the TCI field indicated by the DCI serve as the terminal's first indicated TCI state.

[0133] In some embodiments, the first TCI state includes an active first TCI state, which may also be referred to as a first activated TCI state. The first activated TCI state includes an active joint first TCI state or a downlink first TCI state.

[0134] In some embodiments, the indicated joint first TCI state and the activated joint first TCI state can be collectively referred to as the joint first TCI state, or the first joint TCI state. The first joint TCI state is used to determine at least one of the following: the Physical Downlink Control Channel (PDCCH); the Physical Downlink Shared Channel (PDSCH); the Physical Uplink Control Channel (PUCCH); the Physical Uplink Shared Channel (PUSCH); the Channel State Information-Reference Signal (CSI-RS); and the QCL assumptions of the Sounding Reference Signal (SRS). The phrase "the first joint TCI state is used to determine at least one of the following" can also be understood as "the first joint TCI state is used to determine the transmission configuration of at least one of the following," for example, determining information such as the beam used by the PDCCH.

[0135] In some embodiments, the indicated downlink first TCI state and the activated downlink first TCI state can be collectively referred to as the downlink first TCI state, or the first downlink TCI state (DL TCI state). The first DL TCI state is used to determine at least one of the following: PDCCH; PDSCH; QCL assumptions of CSI-RS. The phrase "the first DL TCI state is used to determine at least one of the following" can also be understood as "the first DL TCI state is used to determine the transmission configuration of at least one of the following," such as determining information like the beam used by the PDCCH.

[0136] Understandably, the joint TCI state can be used to determine the QCL assumptions for the uplink channel or signal, as well as the downlink channel or signal. The DL TCI state can be used to determine the QCL assumptions for the downlink channel or signal.

[0137] In some embodiments, the QCL assumption type includes at least one of the following:

[0138] Type A: Doppler frequency shift, Doppler spread, average delay, delay spread;

[0139] Type B: Doppler frequency shift, Doppler spread;

[0140] Type C: Doppler frequency shift, average delay;

[0141] Type D: Space reception parameters.

[0142] The QCL assumption can be understood as assuming that the above parameters are the same as the parameters obtained from the reference signal resource measurements indicated in each QCL Type in the first TCI state.

[0143] In step S2103, network device 102 sends third information to terminal 101.

[0144] In some embodiments, terminal 101 receives third information sent by network device 102.

[0145] In some embodiments, the network device may configure a list of first TCI states and use third information for at least one of the following: activating one or more first TCI states corresponding to each code point in at least one code point; indicating the sequence number corresponding to the activated first TCI state; and indicating the index of the control resource set pool.

[0146] Optionally, the network device may activate one or more first TCI states corresponding to each code point in at least one code point through third information.

[0147] For example, a network device can activate a first TCI state corresponding to a code point. For instance, if a network device can activate a first TCI state corresponding to a code point in the TCI field of the DCI via a Medium Access Control Element (MAC CE), then the activation of a first TCI state corresponding to a code point by the network device can be considered as either the terminal's indicated TCI state or the terminal's activated TCI state. As another example, a network device can activate a first TCI state corresponding to each of multiple code points in the TCI field of the DCI via a MAC CE. The network device can then indicate one of the activated code points via the DCI, and the code point indicated by the DCI corresponds to a TCI state. In this case, the first TCI state corresponding to the code point indicated by the DCI can be considered as the terminal's indicated TCI state, while the first TCI states corresponding to the multiple code points activated by the MAC CE can be considered as the terminal's activated TCI state.

[0148] For example, a network device can activate multiple first TCI states corresponding to a single code point. For instance, if a network device can activate multiple first TCI states corresponding to a single code point in the TCI field of the DCI via MAC CE, then the activation of one or more first TCI states corresponding to a single code point can be considered as the terminal's indicated TCI state or activated TCI state. Alternatively, if a network device can activate multiple code points in the TCI field of the DCI via MAC CE, each code point corresponding to one or more first TCI states, and the network device can then indicate one of the activated code points via DCI, with the indicated code point corresponding to multiple first TCI states, then the one or more first TCI states corresponding to the indicated code point can be considered as the terminal's indicated TCI state, while the one or more first TCI states corresponding to the multiple code points activated by MAC CE can be considered as the terminal's activated TCI state.

[0149] Optionally, the network device may indicate the sequence number corresponding to the first activated TCI state through third information.

[0150] For example, suppose that the first TCI state corresponding to a certain code point in the TCI field that activates DCI is the first TCI state#1, and that the first TCI state#1 is indicated as the first first TCI state, and the second information may include "first", then the terminal can determine the second reference signal resource based on the first first TCI state#1.

[0151] For example, suppose the first TCI state corresponding to a certain code point in the TCI field that activates DCI is first TCI state #1 and first TCI state #2. The network device can indicate that first TCI state #1 is the first first TCI state and first TCI state #2 is the second first TCI state. When the second information includes "first", the terminal determines the second reference signal resource based on first TCI state #1. When the second information includes "second", the terminal can determine the second reference signal resource based on first TCI state #2.

[0152] For example, suppose the network device activates the first TCI state corresponding to code point #1 and code point #2 in the TCI field of the DCI, where code point #1 corresponds to first TCI state #1 and first TCI state #2, and code point #2 corresponds to first TCI state #3 and first TCI state #4. The network device can indicate that first TCI state #1 is the first TCI state, first TCI state #2 is the second TCI state, first TCI state #3 is the first TCI state, and first TCI state #4 is the second TCI state. When the TCI field of the DCI indicates code point #2, and when the second information includes "first", the terminal can determine the second reference signal resource based on TCI state #3. This disclosure will not provide further examples. Alternatively, the network device indicates that the first TCI state #1 is the first first TCI state corresponding to code point #1, indicates that the first TCI state #2 is the second first TCI state corresponding to code point #1, and indicates that the first TCI state #3 is the third first TCI state corresponding to code point #1. When the second information includes "the third", the terminal can determine the second reference signal resource based on the first TCI state #3.

[0153] For example, suppose the network device activates the first TCI states corresponding to code point #1 and code point #2 respectively. Code point #1 corresponds to both first TCI state #1 and first TCI state #2, and code point #2 corresponds to first TCI state #3. The network device can indicate that first TCI state #1 is the first TCI state, first TCI state #2 is the second TCI state, and first TCI state #3 is the first TCI state. When the TCI field of the first DCI indicates code point #1, and the second information includes "first", the terminal can determine the second reference signal resource based on TCI state #1. When the TCI field of the second DCI indicates code point #2, and at this time, code point #2 only corresponds to the activation of one first TCI state #3, the terminal updates the first TCI state to the first TCI state #3, while the second TCI state remains unchanged, i.e., it is still the first TCI state #2. Then, when the second information includes "second", the terminal can determine the second reference signal resource based on TCI state #2. That is, the sequence number of the first TCI state can also be used for the corresponding update of the first TCI state.

[0154] Alternatively, the network device may use third-party information to instruct the index of the control resource pool.

[0155] For example, each third piece of information is used to activate a first TCI state and contains an index of a control resource set pool. That is, each third piece of information corresponds to a TRP. When the second piece of information includes an index of the control resource set pool, and the index of the control resource set pool included in the second piece of information is the same as the index of the control resource set pool included in the third piece of information, the reference signal resource corresponding to the first TCI state activated by the third piece of information can be determined as the second reference signal resource. For example, the third piece of information is a MAC CE. One MAC CE activates a first TCI state #1 corresponding to a code point and contains an index of 0 for the control resource set pool. Another MAC CE activates a first TCI state #2 corresponding to a code point and contains an index of 1 for the control resource set pool. If the first piece of information includes a first reference signal resource set A and a first reference signal resource set B, the first reference signal resource set A corresponds to the second piece of information a, and the first reference signal resource set B corresponds to the second piece of information b. If the second piece of information a includes an index of 0 for the control resource set pool, then the reference signal resource corresponding to the first TCI state #1 can be determined as the second reference signal resource corresponding to the first reference signal resource set A. If the second information b includes index 1 of the control resource set pool, then the reference signal resource corresponding to the first TCI state #2 can be determined as the second reference signal resource corresponding to the first reference signal resource set B.

[0156] For example, each piece of third information is used to activate a first TCI state for each of the multiple code points in the TCI field of the DCI, and includes an index of a control resource set pool. That is, each piece of third information corresponds to a TRP. The DCI carried on the PDCCH in the CORESET corresponding to the index of the control resource set pool indicates a code point in the TCI field. When the second information includes the index of the control resource set pool, and the index of the control resource set pool included in the second information, the index of the control resource set pool included in the third information, and the index of the control resource set pool corresponding to the CORESET carrying the DCI are the same, the reference signal resource corresponding to the first TCI state of the TCI field indicated by the DCI can be determined as the second reference signal resource. For example, the third piece of information is a MAC CE. Assume a MAC CE activates the first TCI state corresponding to each of multiple code points, where code point '000' corresponds to first TCI state #1. This MAC CE contains an index of 0 for the Control Resource Set Pool, and the first DCI corresponds to an index of 0 for the CORESETPoolIndex of the CORESET, indicating code point '000' in the TCI field. Assume another MAC CE activates the first TCI state corresponding to each of multiple code points, where code point '001' corresponds to first TCI state #2. This MAC CE contains an index of 1 for the Control Resource Set Pool, and the second DCI corresponds to an index of 1 for the CORESETPoolIndex of the CORESET, indicating code point '001' in the TCI field. If the first information includes a first reference signal resource set A and a first reference signal resource set B, where the first reference signal resource set A corresponds to second information a and the first reference signal resource set B corresponds to second information b, and if the second information a includes index 0 of the control resource set pool, then the reference signal resource corresponding to the first TCI state #1 can be determined as the second reference signal resource corresponding to the first reference signal resource set A. If the second information b includes index 1 of the control resource set pool, then the reference signal resource corresponding to the first TCI state #2 can be determined as the second reference signal resource corresponding to the first reference signal resource set B.

[0157] In some embodiments, the activation of a first TCI state corresponding to a code point by a network device can also be understood as a mapping relationship between the network device activating the code point and the first TCI state. For example, if a code point and a first TCI state have a mapping relationship, activating this mapping relationship by the network device means that the network device activates one TCI state corresponding to that code point. As another example, if a code point and multiple first TCI states have a mapping relationship, activating this mapping relationship by the network device means that the network device activates multiple first TCI states corresponding to that code point. As yet another example, if there are two code points, each code point having a mapping relationship with two first TCI states, activating these two mapping relationships by the network device means that the network device activates the first TCI states corresponding to each of these two code points, activating a total of four first TCI states. It is understood that the above examples are exemplary and not limited thereto.

[0158] In some embodiments, for the S-DCI MTRP scenario, the second information may include the sequence number of the first TCI state. For the M-DCI MTRP scenario, the second information may include the sequence number of the first TCI state or the index of the control resource set pool. It is understood that in the S-DCI MTRP scenario, one code point of a DCI can correspond to one or more TCI states, but different DCIs are often not configured with different control resource set pool indices. Therefore, in the S-DCI MTRP scenario, the terminal can determine the second reference signal resource by indicating the sequence number of the first TCI state; that is, the second information may include the sequence number of the first TCI state. In the M-DCI MTRP scenario, different control resource sets are often configured with different control resource set pool indices. Therefore, in the M-DCI MTRP scenario, the terminal can determine the second reference signal resource by using the index of the control resource set pool; that is, the second information may include the sequence number of the first TCI state or the index of the control resource set pool. Alternatively, regardless of whether it's an S-DCI MTRP scenario or an M-DCI MTRP scenario, network devices can also use an implicit method to indicate the second information. That is, the first information includes two information fields, and different information fields are used to correspond to different second information. In other words, different information fields are used to indicate the first reference signal resource set corresponding to different TRPs. For a detailed explanation, please refer to the above embodiments, which will not be repeated here. By selecting different methods to determine the second information in different scenarios, the flexibility and efficiency of the communication system can be improved.

[0159] Understandably, in an S-DCI MTRP scenario, although one DCI corresponds to one control resource set, network devices can configure multiple control resource sets for a terminal. For example, multiple control resource sets with different periods can be configured to schedule data transmission for the terminal using DCIs on different control resource sets. In this case, different control resource sets are often not configured with different indexes for the control resource set pool.

[0160] In some embodiments, the third information includes at least one of the following: MAC CE; DCI. The following embodiments of this disclosure use MAC CE as an example, but are not limited thereto. When the third information includes MAC CE and DCI, MAC CE can be used to activate one or more first TCI states corresponding to each of a plurality of code points, and DCI can indicate one of the multiple code points. For example, the TCI field of DCI can be used to dynamically indicate which code point corresponding to one or more first TCI states is currently in use.

[0161] Optionally, an initial TCI state list can be configured via Radio Resource Control (RRC) signaling. The MAC CE activates a mapping relationship between code points in the TCI field of the DCI and one or more TCI states. The MAC CE also indicates the sequence number of the one or more TCI states corresponding to each code point, for example, whether it is the first TCI state or the second TCI state. The MAC CE can activate one or more TCI states corresponding to multiple code points, for example, up to eight code points can be activated. Of course, in some cases, the MAC CE can also activate more code points, which is not limited in this disclosure. When the MAC CE activates only one or more TCI states corresponding to a code point, the one or more TCI states corresponding to that code point are the first TCI state, i.e., the indicated TCI state or the activated TCI state. When the MAC CE activates one or more TCI states corresponding to more than one code point, the TCI field of the DCI can be used to dynamically indicate which one or more TCI states corresponding to the code point currently in use. That is, one or two TCI states corresponding to the code point in the TCI field of the DCI are the first TCI state, i.e., the indicated TCI state, while the TCI state activated by the MAC CE is the activated TCI state.

[0162] Optionally, the sequence number of the first TCI state is also used for the corresponding update of the first TCI state: for example, the first TCI state corresponding to code point #1 is TCI state #3, and the second TCI state is TCI state #4; code point #2 only corresponds to the first TCI state as TCI state #5. Therefore, when the code point of the TCI field in the DCI is code point #1, the terminal's first TCI state is TCI state #3, and the second first TCI state is TCI state #4. When the code point of the TCI field in a subsequent DCI transmission is code point #2, the terminal only updates the first TCI state, that is, the terminal's first TCI state is updated to TCI state #5, while the second first TCI state remains unchanged as TCI state #4.

[0163] Optionally, an initial TCI state list can be configured via Radio Resource Control (RRC) signaling. A MAC CE activates a mapping relationship, which also includes the value corresponding to the CORESETPoolIndex. This indicates that the MAC CE activates the mapping relationship for the first TCI state corresponding to that CORESETPoolIndex. This mapping relationship is the mapping relationship between each code point in the TCI field of the DCI and a first TCI state, since it corresponds to only one TRP. The mapping relationship between code points and TCI states for different TRPs is activated by different MAC CEs. The code points for different TRPs are determined by the CORESETPoolIndex of the CORESET corresponding to the DCI in which the code point is located.

[0164] It is understood that step S2102 is optional, and the execution order of steps S2101 and S2102 is not limited in this disclosure.

[0165] In step S2104, terminal 101 sends fourth information and / or fifth information to network device 102.

[0166] In some embodiments, network device 102 receives fourth and / or fifth information sent by terminal 101.

[0167] In some embodiments, when the measurement result of the second reference signal resource satisfies an event, or when the measurement results of the first and second reference signal resources satisfy an event, the terminal sends fourth and / or fifth information. For example, if the measurement result of the second reference signal resource is lower than a threshold value (assumed to be threshold value 1), that is, the beam quality of the current beam is lower than the threshold value, then Event 1 in the above embodiments is satisfied, and a report can be triggered. As another example, if the measurement result of the first reference signal resource is higher than the measurement result of the second reference signal resource by a threshold value (assumed to be threshold value 2), that is, the beam quality of the new beam is higher than the beam quality of the current beam by a threshold value, then Event 2 in the above embodiments is satisfied, and a report can be triggered. It is understood that the events are not limited to the examples of Event 1 and Event 2. For example, if the measurement result of the first reference signal resource is higher than a threshold value (assumed to be threshold value 3), that is, the beam quality of the new beam is higher than the threshold value, a report can also be triggered, and this disclosure is not limited thereto. The magnitude of threshold values ​​1, 2, and 3 is not limited in this disclosure.

[0168] In some embodiments, the fourth information is used to inform the network device terminal that there is a report to be sent.

[0169] Optionally, the terminal informs the network device of a report to be sent, and the network device can configure resources for the terminal to send the report. The fourth piece of information can be used to request the network device to configure dynamically granted physical uplink shared channel (DG PUSCH) resources.

[0170] Optionally, the terminal informs the network device of a report to be sent and instructs the terminal to send the first report on the PUSCH resource. For example, the network device can pre-configure CG PUSCHs, and the terminal can determine a transmission timing from the pre-configured CG PUSCHs for sending the report. For instance, it can select the CG PUSCH N symbols after the fourth message is sent, or the first CG PUSCH after the fourth message is sent, and send the first report on that CG PUSCH. The terminal informs the network device that it will report the report to the network device on the CG PUSCH by sending the fourth message, so that the network device can receive the report on the first CG PUSCH after the fourth message or on the CG PUSCH N symbols after the fourth message. The CG PUSCH can be Type 1 CG PUSCH, but is not limited to this. N is a positive integer.

[0171] In some embodiments, the fifth piece of information includes a report.

[0172] In some embodiments, the fourth information may be carried by PUCCH, and the resources occupied by the fourth information are PDCCH resources, but this is not a limitation.

[0173] In some embodiments, the fifth information may be carried by a PUSCH, and the resources occupied by the fifth information are PUSCH resources, but this is not limited to this. The PUSCH includes at least one of the following: CG PUSCH; DG PUSCH.

[0174] In some embodiments, when the fifth information is carried by the DG PUSCH, the DCI that schedules the DG PUSCH is also used to activate the transmission of the report.

[0175] In some embodiments, the fourth information and / or the fifth information have the following characteristics: when the corresponding second information is different, the resources occupied by the bearer signaling are the same; or, when the corresponding second information is different, the resources occupied by the bearer signaling are different. The second information corresponding to the fourth information and / or the fifth information can be understood as follows: the terminal determines the second reference signal resource based on the second information, and sends the fourth information and / or the fifth information when the measurement result of the second reference signal resource satisfies an event, or when the measurement result of the first reference signal resource and the measurement result of the second reference signal resource satisfy an event. Therefore, the second information corresponding to the second reference signal resource that triggers the fourth information and / or the fifth information is the second information corresponding to the fourth information and / or the fifth information. Different second information corresponding to the fourth information and / or the fifth information can also be understood as different second reference signal resources triggering the fourth information and / or the fifth information. Different second information corresponding to the fourth information and / or the fifth information can also be understood as different sets of first reference signal resources triggering the fourth information and / or the fifth information. Different second information corresponding to the fourth information and / or the fifth information can also be understood as different TRPs triggering the fourth information and / or the fifth information. The fact that the second information corresponding to the fourth and / or fifth information is different can also be understood as the CORESETPoolIndex that triggers the fourth and / or fifth information being different. Similarly, the fact that the second information corresponding to the fourth and / or fifth information is different can also be understood as the first TCI state that triggers the fourth and / or fifth information being different.

[0176] Optionally, when the second information corresponds to the fourth information, the resources occupied by the signaling carrying the fourth information can be the same.

[0177] Optionally, when the second information corresponds to the fourth information, the resources occupied by the signaling carrying the fourth information can be different.

[0178] Optionally, when the second information corresponds to the fifth information, the resources occupied by the signaling carrying the fifth information can be the same.

[0179] Optionally, when the second information corresponding to the fifth information is different, the resources occupied by the signaling carrying the fifth information can be different.

[0180] In some embodiments, if the signaling carrying multiple pieces of fifth information occupies the same resource, and that resource cannot carry multiple pieces of fifth information simultaneously, at least one piece of fifth information can be discarded based on priority. The priority is determined based on at least one of the following: the cell index corresponding to the fifth information; the sequence number of the first TCI state corresponding to the fifth information; the index of the control resource set pool corresponding to the fifth information; the search space period associated with the control resource set corresponding to the fifth information; and the identifier of the control resource set corresponding to the fifth information.

[0181] Optionally, priority can be based on the cell index corresponding to the fifth piece of information. For example, the lower the cell index, the higher the priority. For example, the cell index can be index#1, index#2, etc., where index#1 is lower than index#2, and the fifth piece of information at index#1 has a higher priority than the fifth piece of information at index#2. For example, if the cell index corresponding to the first piece of information is lower than the cell index corresponding to the second piece of information, then the first piece of information has a higher priority than the second piece of information. The second piece of information can be discarded. If there are more than two pieces of information, all the fifth pieces of information are sorted by priority from highest to lowest based on the cell index, and the last piece of information in the sorted order is discarded until the resource can carry the remaining fifth pieces of information. For example, if the priority from highest to lowest is the first piece of information, the second piece of information, and the third piece of information, the third piece of information can be discarded first. If the resource can carry the first and second pieces of information, then the discarding can stop, and the first and second pieces of information can be sent. If the resource still cannot carry the first and second pieces of information, then the second piece of information can continue to be discarded, and so on, until the resource can carry the remaining fifth pieces of information. This disclosure does not provide examples of all such cases.

[0182] Optionally, the priority can be determined based on the sequence number of the first TCI state corresponding to the fifth piece of information. For example, the smaller the sequence number of the first TCI state, the higher the priority. Taking two first TCI states as an example, the priority of the first first TCI state is higher than that of the second first TCI state. If the first piece of fifth information corresponds to the first first TCI state, and the first TCI state corresponding to the second piece of fifth information is the second first TCI state, then the priority of the first piece of fifth information is higher than that of the second piece of fifth information. The second piece of fifth information can be discarded. If there are more than two pieces of fifth information, all the fifth information is sorted from highest to lowest priority based on the sequence number of the corresponding first TCI state, and the fifth information with the lowest priority is discarded until the resource can accommodate the remaining fifth information. For specific instructions on discarding, please refer to the optional example above, which will not be repeated in this disclosure.

[0183] Optionally, the priority can be determined based on the index of the control resource pool corresponding to the fifth piece of information. For example, the smaller the index of the control resource pool, the higher the priority. Taking two control resource pool indices as an example, the indexes of the control resource pools can be CORESETPoolIndex0 and CORESETPoolIndex1. CORESETPoolIndex0 is lower than CORESETPoolIndex1, and the priority of the fifth piece of information corresponding to CORESETPoolIndex0 is higher than the priority of the fifth piece of information corresponding to CORESETPoolIndex1. Therefore, the fifth piece of information corresponding to CORESETPoolIndex1 can be discarded. If there are more than two pieces of fifth information, all the fifth pieces of information are sorted from highest to lowest priority based on their corresponding CORESETPoolIndex, and the fifth piece of information with the lowest priority is discarded, until the resource can accommodate the remaining fifth pieces of information. For specific instructions on discarding, please refer to the optional example above, which will not be repeated in this disclosure.

[0184] Optionally, the priority can be determined based on the search space period associated with the control resource set corresponding to the fifth piece of information. For example, the smaller the search space period associated with the control resource set corresponding to the fifth piece of information, the higher the priority. For instance, if the search space period associated with the control resource set corresponding to the first piece of information is smaller than the search space period associated with the control resource set corresponding to the second piece of information, then the priority of the first piece of information is higher than that of the second piece of information, and the second piece of information can be discarded. If there are more than two pieces of information, all the fifth pieces of information are sorted from highest to lowest priority based on the size of the search space period associated with their corresponding control resource sets, and the fifth piece of information with the lowest priority is discarded, until the resource can accommodate the remaining fifth pieces of information. For specific instructions on discarding, please refer to the optional examples above, which will not be repeated in this disclosure.

[0185] Optionally, the priority can be determined based on the identifier of the control resource set corresponding to the fifth information. For example, the larger the identifier of the control resource set, the higher the priority. For example, the identifier of the control resource set can be a decimal number, such as 1, 2, 3, etc., or a bit value. For example, the bit values ​​corresponding to identifiers 0001 and 0011 are different, and their sizes can be compared. For example, after the terminal determines the highest priority CORESET, the fifth information corresponding to the CORESETPoolIndex or indicated TCI state used by that CORESET has the highest priority. The fifth information corresponding to the CORESETPoolIndex or indicated TCI state used by the CORESET can be sorted from high to low priority according to the CORESET priority, and the fifth information with the lowest priority is discarded until the resource can carry the remaining fifth information. For specific instructions on discarding, refer to the above optional examples; this disclosure will not repeat them here. Optionally, the priority can be determined based on the identifier of the control resource set corresponding to the fifth information. For example, the smaller the identifier of the control resource set, the higher the priority. For example, the identifier of a control resource set can be a decimal number, such as 1, 2, 3, etc., or a bit value. For example, the bit values ​​corresponding to identifiers 0001 and 0011 are different, and their sizes can be compared. For example, after the terminal determines the highest priority CORESET, the fifth information corresponding to the CORESETPoolIndex or indicated TCI state used by that CORESET has the highest priority. The fifth information corresponding to the CORESETPoolIndex or indicated TCI state used by the CORESET can be sorted from highest to lowest priority according to the CORESET priority, and the lowest priority fifth information is discarded until the resource can accommodate the remaining fifth information. Specific instructions on discarding are given in the optional examples above, and will not be repeated in this disclosure.

[0186] It is understood that the above-mentioned optional examples for determining priority can be implemented individually or in combination. Taking the cell index and the control resource pool index as an example, they can jointly determine the priority of the fifth piece of information. For example, if the cell indexes are the same, the priority of the fifth piece of information is determined based on the control resource pool index; if the control resource pool indexes are the same, the priority of the fifth piece of information is determined based on the cell index. If both the cell index and the control resource pool index are different, weights can be assigned to the influence of these two factors on the priority, and then the weights are summed to obtain the final priority value. For example, assuming the cell index weight percentage is A% and the control resource pool index weight percentage is B%, if the cell index of the first piece of fifth information is #1 and the cell index of the second piece of fifth information is #3, the priority value determined by the first piece of fifth information based on the cell index is 1*A%, and the priority value determined by the second piece of fifth information based on the cell index is 3*B%. If the index of the control resource set pool for the first fifth message is 2, and the index of the control resource set pool for the second fifth message is 1, then the priority value determined by the control resource set pool index for the first fifth message is 5*A%, and the priority value determined by the control resource set pool index for the second fifth message is 1*B%. Therefore, the final priority value of the first fifth message is 1*A% + 5*A%, and the final priority value of the second fifth message is 3*B% + 1*B. Since the smaller the cell index and the control resource set pool index, the higher the priority, the smaller the final priority value, the higher the priority of the fifth message, thus determining the priority of the fifth message. For example, different methods can be used to determine the priority of the fifth message in different situations. For instance, in the MTRP S-DCI scenario, the cell index can be used to determine the priority of the fifth message; in the MTRP M-DCI scenario, the control resource set pool index can be used. This disclosure does not limit this approach. It is understood that the examples above are merely illustrative and this disclosure does not limit them. The factors for determining the priority of the fifth information can be any combination of one or more factors. When multiple factors jointly determine the priority of the fifth information, which factor has a greater influence on the priority of the fifth information and is given priority can be determined according to the actual situation, and this disclosure does not limit it.

[0187] It is understandable that the first fifth piece of information, the second fifth piece of information, etc. in the above optional examples do not have any order. "First" and "second" are only used to distinguish different fifth pieces of information. Only after sorting according to priority will there be a priority order among multiple fifth pieces of information.

[0188] In some embodiments, the signaling carrying the fourth information may be PUCCH. The resources occupied by PUCCH may include time domain resources, frequency domain resources, code domain resources, spatial domain resources, etc., which are not limited in this disclosure.

[0189] In some embodiments, the signaling carrying the fifth information may be PUSCH, and the resources occupied by PUSCH may include time domain resources, frequency domain resources, code domain resources, spatial domain resources, etc., which are not limited in this disclosure.

[0190] In some embodiments, the fifth information may also include a CSI report configuration identifier (CSIreportconfig ID), and the CSIreportconfig ID in the fifth information may be different for different sets of first reference signal resources.

[0191] In step S2105, network device 102 sends the sixth information to terminal 101.

[0192] In some embodiments, terminal 101 receives sixth information sent by network device 102.

[0193] In some embodiments, the sixth information includes a second set of reference signal resources, but does not indicate the second information corresponding to the second set of reference signal resources. It is understood that the sixth information and the first information serve a similar purpose: configuring the reference signal resource set corresponding to the new beam. The difference lies in that the first information configures the first set of reference signal resources while indicating the second information corresponding to it, while the sixth information configures the second set of reference signal resources without indicating the second information corresponding to it. The first information can be TRP-level configuration information, and the sixth information can be cell-level configuration information. Alternatively, the first information can be MTRP-level configuration information, and the sixth information can be S(Single)TRP-level configuration information.

[0194] In step S2106, terminal 101 determines the fourth reference signal resource based on the second TCI state pre-indicated by network device 102.

[0195] In some embodiments, the sixth information is cell-level configuration information, i.e., it does not distinguish between TRPs. Alternatively, the sixth information can be configuration information corresponding to a STRP. Therefore, the sixth information does not need to indicate which first reference signal resource set corresponds to different TRPs. The terminal can determine the fourth reference signal resource based on the second TCI state pre-indicated by the network device, such as the TCI state corresponding to a cell or the TCI state corresponding to a single TRP.

[0196] In some embodiments, the first reference signal resource set and the second reference signal resource set correspond to the same serving cell of the terminal, or different serving cells, or one corresponds to a serving cell and the other to a non-serving cell. The non-serving cell can also be referred to as a cell corresponding to an additional PCI (Physical Cell ID).

[0197] In some embodiments, the second set of reference signal resources includes at least one third reference signal resource. The third reference signal resource functions similarly to the first reference signal resource, and the fourth reference signal resource functions similarly to the second reference signal resource. The third and fourth reference signal resources can be used to trigger reports. For example, the third reference signal resource can correspond to a new beam, and the fourth reference signal resource can correspond to the current beam. At least one of the beam quality of the current beam and the beam quality of the new beam can be used to evaluate events. For example, the third set of reference signal resources includes at least one third reference signal resource. Measuring the reference signal on the third reference signal resource can characterize the beam quality of the new beam. Measuring the reference signal on the fourth reference signal resource can characterize the beam quality of the current beam. For example, the measurement results can include Layer 1 reference signal received power (L1-RSRP), Layer 1 signal to interference plus noise ratio (L1-SINR), etc., but are not limited to these. For example, if the measurement result of the fourth reference signal resource is lower than a threshold value (assumed to be threshold value 1), meaning the beam quality of the current beam is lower than the threshold value, then Event 1 in the above embodiment is satisfied, and a report can be triggered. As another example, if the measurement result of the third reference signal resource is higher than the measurement result of the fourth reference signal resource by one threshold value (assumed to be threshold value 2), meaning the beam quality of the new beam is higher than the beam quality of the current beam by one threshold value, then Event 2 in the above embodiment is satisfied, and a report can be triggered. It is understood that the events are not limited to the examples of Event 1 and Event 2. For example, if the measurement result of the third reference signal resource is higher than a threshold value (assumed to be threshold value 3), meaning the beam quality of the new beam is higher than the threshold value, a report can also be triggered, and this disclosure is not limited thereto. The magnitude of threshold values ​​1, 2, and 3 is not limited in this disclosure.

[0198] In step S2107, terminal 101 sends seventh information and / or eighth information to network device 102.

[0199] In some embodiments, network device 102 receives seventh and / or eighth information sent by terminal 101.

[0200] In some embodiments, the seventh information is used to inform the network device terminal that there is a report to be sent. The function of the seventh information is similar to that of the fourth information, and will not be described again in this disclosure.

[0201] In some embodiments, the eighth information includes a report. The function of the eighth information is similar to that of the fifth information, and will not be described again in this disclosure.

[0202] In some embodiments, the fourth, fifth, seventh, and eighth information have the following characteristics: the bearer signaling of the fourth information occupies the first resource, and the bearer signaling of the seventh information occupies the second resource; and / or, the bearer signaling of the fifth information occupies the third resource, and the bearer signaling of the eighth information occupies the fourth resource.

[0203] Optionally, the signaling carrying the fourth information occupies the first resource, and the signaling carrying the seventh information occupies the second resource. The first resource and the second resource can be the same or different.

[0204] Optionally, the signaling for the fifth information occupies the third resource, and the signaling for the eighth information occupies the fourth resource. The third and fourth resources may be the same or different.

[0205] In some embodiments, if the signaling carrying multiple eighth messages occupies the same resource, and that resource cannot carry multiple eighth messages simultaneously, at least one of the multiple eighth messages can be discarded based on priority. The priority is determined based on the cell index corresponding to the eighth message.

[0206] Optionally, priority can be based on the cell index corresponding to the eighth piece of information. For example, the lower the cell index, the higher the priority. For example, the cell index can be index#1, index#2, etc., where index#1 is lower than index#2, and the eighth piece of information at index#1 has a higher priority than the eighth piece of information at index#2. For example, if the cell index corresponding to the first eighth piece of information is lower than the cell index corresponding to the second eighth piece of information, then the first eighth piece of information has a higher priority than the second eighth piece of information. The second eighth piece of information can be discarded. If there are more than two pieces of eighth information, all the eighth pieces of information are sorted by priority from highest to lowest based on the cell index, and the last eighth piece of information in the sorted order is discarded until the resource can carry the remaining eighth pieces of information. For example, if the priority from highest to lowest is the first eighth piece of information, the second eighth piece of information, and the third eighth piece of information, the third eighth piece of information can be discarded first. If the resource can carry the first and second eighth pieces of information, then the discarding can stop, and the first and second eighth pieces of information can be sent. If the resource still cannot carry the first and second eighth pieces of information, then the second eighth piece of information can continue to be discarded, and so on, until the resource can carry the remaining eighth pieces of information. This disclosure does not provide examples of all such cases.

[0207] In some embodiments, if the third and fourth resources are the same, i.e., the signaling for carrying the fifth and eighth information occupies the same resource, and the third resource cannot carry both the fifth and eighth information simultaneously, then at least one of the fifth and eighth information can be discarded based on priority; wherein the priority is determined based on at least one of the following: the cell index corresponding to the fifth and / or eighth information; the priority of the eighth information is higher than the priority of the fifth information; the priority of the eighth information is lower than the priority of the fifth information.

[0208] Optionally, the priority can be based on the cell index corresponding to the fifth and / or eighth information. For example, the lower the cell index, the higher the priority. For instance, the cell index can be index#1, index#2, etc., where index#1 is lower than index#2, and the fifth and / or eighth information of index#1 has a higher priority than the fifth and / or eighth information of index#2. For example, if the cell index corresponding to the fifth information is lower than the cell index corresponding to the eighth information, then the fifth information has a higher priority than the eighth information, and the eighth information can be discarded. If the third resource can send the fifth information after discarding the eighth information, then the terminal sends the fifth information. If, after discarding the eighth information, the third resource still cannot send multiple pieces of fifth information due to the existence of multiple pieces of fifth information, then the terminal can determine which fifth information has the lower priority to discard based on the aforementioned priorities among the different pieces of fifth information. Conversely, if the cell index corresponding to the fifth information is higher than the eighth information, the fifth information has a lower priority than the eighth information, and the fifth information can be discarded. If the third resource can send the eighth information after discarding the fifth information, then the terminal sends the eighth information. If, after discarding the fifth information, the third resource still cannot send multiple eighth information messages due to the existence of multiple eighth information messages, then the terminal can also determine to discard the eighth information message with lower priority according to the priority among different eighth information messages. The method for determining the priority among different eighth information messages can refer to the above embodiment. It is understood that this optional example is illustrated using the third resource as an example, but since the third resource and the fourth resource are the same, the third resource in this optional example can be replaced by the fourth resource.

[0209] Optionally, the priority of the eighth message can be higher than that of the fifth message. For example, a network device can be configured to have a default priority of the eighth message higher than that of the fifth message, or a predefined or protocol-specified priority of the eighth message higher than that of the fifth message. If the third resource cannot send both the fifth and eighth messages simultaneously, the terminal can discard the fifth message. It is understood that if the third resource can send the eighth message after discarding the fifth message, the terminal will send the eighth message; if, after discarding the fifth message, the third resource still cannot send multiple eighth messages due to the existence of multiple eighth messages, the terminal can also determine to discard the eighth message with the lower priority based on the priority among the different eighth messages.

[0210] Optionally, the priority of the fifth piece of information can be higher than that of the eighth piece of information. For example, the network device can be configured to allow the terminal to default to a higher priority for the fifth piece of information than for the eighth piece of information, or the priority of the fifth piece of information can be predefined or specified by a protocol. If the third resource cannot send both the fifth and eighth pieces of information simultaneously, the terminal can discard the eighth piece of information. If, after discarding the eighth piece of information, the third resource can still send the fifth piece of information because multiple pieces of fifth information exist, the terminal can determine which fifth piece of information has the lower priority to discard based on the aforementioned priorities among the different pieces of fifth information.

[0211] It is understandable that the above-mentioned options for determining priorities can be implemented individually or in combination. For example, the priority of the fifth piece of information being higher than that of the eighth piece of information, and vice versa, can be combined, with the appropriate method used to determine priorities in different situations. For instance, in an MTRP S-DCI scenario, the priorities of the fifth and eighth pieces of information can be determined based on the principle that the eighth piece of information has a higher priority than the fifth piece of information. In an MTRP M-DCI scenario, the priorities of the fifth and eighth pieces of information can be determined based on the principle that the fifth piece of information has a higher priority than the eighth piece of information. For another example, if multiple pieces of fifth information and one piece of eighth information simultaneously occupy the third resource, the priority of the eighth piece of information can be higher than that of the fifth piece of information; conversely, if multiple pieces of eighth information and one piece of fifth information simultaneously occupy the third resource, the priority of the fifth piece of information can be higher than that of the eighth piece of information. For yet another example, when the communication system throughput is high, or the channel quality is good and the service is not busy, the fifth piece of information is TRP-level information, and the eighth piece of information is cell-level information; the priority of the fifth piece of information can be higher than that of the eighth piece of information. When the communication system throughput is low, or the channel quality is poor and the service is busy, the priority of the eighth piece of information can be higher than that of the fifth piece of information. Of course, the examples in this disclosure are merely illustrative. The factors that affect priority mentioned above can be any combination of one or more factors. When multiple factors jointly determine priority, which factor has a greater impact on priority and is given priority can be determined according to the actual situation. This disclosure does not limit this.

[0282] Figure 5 is a schematic diagram illustrating the communication method interaction according to an embodiment of the present disclosure. As shown in Figure 5, the embodiments of the present disclosure relate to a communication method, which includes:

[0283] Step S5101: The network device sends the first information to the terminal.

[0284] In step S5102, the terminal determines the second reference signal resource based on the second information.

[0285] In some embodiments, the above methods may include the methods of the embodiments related to the communication system 100, terminal 101, and network device 102, which will not be described again here.

[0286] This disclosure provides a communication method as follows:

[0287] In some embodiments, the terminal receives configuration information, which includes at least one set of reference signal resources and an indication of the indicated TCI state corresponding to the set of reference signal resources or the CORESETPoolIndex corresponding to the set of reference signal resources.

[0288] In some embodiments, the indicated TCI state includes a first indicated TCI state or a second indicated TCI state. (That is, the configuration information only indicates whether the reference signal resource set corresponds to the first or the second indicated TCI state, and which is the first or the second indicated TCI state is given by subsequent signaling.)

[0289] In some embodiments, the indicated TCI state includes a joint / DL TCI state. The joint TCI state can be used to indicate the QCL (quasi-co-location) assumptions for PDCCH, PDSCH, PUCCH, PUSCH, CSI-RS, and SRS. The DL TCI state is used to indicate the assumptions for PDCCH, PDSCH, and CSI-RS. The QCL assumption type includes at least one of the following:

[0290] 'typeA':{Doppler shift,Doppler spread,average delay,delay spread}

[0291] 'typeB':{Doppler shift,Doppler spread}

[0292] 'typeC':{Doppler shift,average delay}

[0293] 'typeD':{Spatial Rx parameter}

[0294] In some embodiments, a MAC CE is received, and a first or second indicated TCI state is determined based on the MAC CE.

[0295] In some embodiments, this scheme is a scheme for the MTRP S-DCI scenario, where the indicated TCI state is indicated by RRC+MAC CE+DCI. RRC configures a TCI state list, and MAC CE activates a mapping relationship between codepoints in the DCI's TCI field and one or two TCI states. MAC CE also indicates whether the one or two TCI states corresponding to each codepoint are the first or second TCI state. MAC CE can activate up to eight codepoints corresponding to one or two TCI states. When MAC CE activates only one codepoint corresponding to one or two TCI states, those one or two TCI states are the indicated TCI state. When MAC CE activates more than one codepoint corresponding to one or two TCI states, the DCI's TCI field needs to dynamically indicate which codepoint corresponding to one or two TCI states is currently used; in this case, the one or two TCI states corresponding to the codepoints in the DCI's TCI field are the indicated TCI states. Whether the one or two TCI states corresponding to each codepoint correspond to the first TCI state or the second TCI state is also used for the corresponding update of the TCI state: for example, the first TCI state corresponding to codepoint #1 is TCI state #3, and the second TCI state is TCI state #4; codepoint #2 only corresponds to the first TCI state as TCI state #5. So when the codepoint of the TCI field of the DCI is codepoint #1, the terminal's first indicated TCI state is TCI state #3, and the second indicated TCI state is TCI state #4; and when the codepoint of the TCI field of the DCI sent later is codepoint #2, the terminal only updates the first TCI state, that is, the terminal's first indicated TCI state is updated to TCI state #5, while the second indicated TCI state remains unchanged as TCI state #4.

[0296] In some embodiments, CORESETPoolIndex includes a value of 0 or 1. The CORESETPoolIndex is used to determine whether the reference signal resource set corresponds to the first or second indicated TCI state.

[0297] a) For example, Value 0 is related to the first indicated TCI state, and Value 1 is related to the second indicated TCI state.

[0298] b) This scenario corresponds to the MTRP M-DCI case. The method for indicating the TCI state is also RRC+MAC CE+DCI. RRC configures a TCI state list, and MAC CE activates a mapping relationship. MAC CE also includes the value corresponding to CORESETPoolIndex, indicating that the MAC CE activates the mapping relationship of the TCI state corresponding to the CORESETPoolIndex. This mapping relationship is the mapping relationship between each codepoint in the TCI field of the DCI and a TCI state, because it corresponds to only one TRP. The mapping relationship between codepoints and TCI states of different TRPs is activated by different MAC CEs. The codepoints of different TRPs are determined by the CORESETPoolIndex of the CORESET corresponding to the DCI where the codepoint is located.

[0299] In some embodiments, the terminal determines a first reference signal resource corresponding to the indicated TCI state of the reference signal resource set. The first reference signal resource is the CSI-RS or the source SSB of the CSI-RS corresponding to the QCL Type D of the indicated TCI state. Upon a beam quality satisfaction event of the first reference signal resource, or upon a beam quality satisfaction event of at least one reference signal resource in the first reference signal resource and the reference signal resource set, the terminal transmits first information and / or second information, wherein the first information is transmitted based on PUCCH and the second information is transmitted based on PUSCH.

[0300] a) Here, the event refers to the time event in the background.

[0301] b) The second information includes at least one of RS ID (CSI-RS ID or SSB ID) and L1-RSRP / L1-SINR.

[0302] In some embodiments, the first information is used to inform the network device terminal that it needs to send a beam report.

[0303] In some embodiments, PUSCH includes DCI-scheduled DG PUSCH or configuration-authorized CG PUSCH.

[0304] In some embodiments, in the case of DCI-scheduled DG PUSCH, DCI is also used to instruct the activation of event-triggered beam reporting.

[0305] In some embodiments, the PUCCH resources corresponding to the first information for different indicated TCI states or different CORESETPoolIndex configuration information (reporting configurations for different TRPs) may be the same or different.

[0306] In some embodiments, the PUSCH resources corresponding to the second information for different indicated TCI states or different CORESETPoolIndex configuration information (reporting configurations for different TRPs) may be the same or different.

[0307] In some embodiments, different sets of reference signal resources correspond to different CSIreportconfig IDs, and the second information includes the CSIreportconfig ID.

[0308] In some embodiments, the PUCCH resources corresponding to the first configuration information (the configuration information corresponding to the indicated TCI state or CORESETPoolindex of claim 1, i.e., the TRP-level reporting configuration information) and the second configuration information (the configuration information does not contain the indicated TCI state or CORESETPoolindex, such as the case of STRP, i.e., the cell-level reporting configuration information) are the same or different.

[0309] In some embodiments, the PUSCH resources corresponding to the first configuration information (the configuration information corresponding to the indicated TCI state or CORESETPoolindex of claim 1, i.e., the TRP-level reporting configuration information) and the second configuration information (the configuration information does not contain the indicated TCI state or CORESETPoolindex, such as the case of STRP, i.e., the cell-level reporting configuration information) are the same or different.

[0310] In some embodiments, when the second information corresponding to multiple report configuration information needs to be sent on the same PUSCH resource and the PUSCH resource cannot simultaneously carry the second information corresponding to all report configuration information (i.e., insufficient resources), the second information corresponding to the report configuration information with the higher priority is sent based on priority. Priority is determined based on at least one of the following:

[0311] First, it's determined based on the cell index corresponding to the report configuration information; for example, the lower the cell index, the higher the priority. Another example is if different TRPs correspond to the same cell index.

[0312] The priority is determined based on the value of CORESETPoolIndex; for example, a smaller value indicates a higher priority.

[0313] It is determined based on the indicated TCI state. For example, the first indicated TCI state has a higher priority than the second indicated TCI state.

[0314] The priority is determined based on the duration of the search space associated with the CORESET. For example, among all CORESETs, the shorter the duration of the associated search space, the higher the priority. After determining the highest priority CORESET, the second piece of information corresponding to the report configuration information of the CORESETPoolIndex or indicated TCI state used by that CORESET has the highest priority.

[0315] The priority is determined based on the size of the ID corresponding to the CORESET. For example, among all CORESETs, the larger the ID, the higher the priority. After determining the CORESET with the highest priority, the second piece of information corresponding to the report configuration information of the CORESETPoolIndex or indicated TCI state used by that CORESET has the highest priority.

[0316] This disclosure also provides an apparatus for implementing any of the above methods. For example, an apparatus is provided that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Alternatively, another apparatus is provided that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0317] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0318] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).

[0319] Figure 6a is a schematic diagram of the terminal structure proposed in an embodiment of this disclosure. As shown in Figure 6a, the terminal 6100 may include at least one of a transceiver module 6101 and a processing module 6102. The transceiver module 6101 is used to receive first information, which includes a first set of reference signal resources. The first information is used to determine second information corresponding to the first set of reference signal resources. The terminal determines a second reference signal resource based on the second information. The first set of reference signal resources includes at least one first reference signal resource, and at least one of the first and second reference signal resources is used to trigger a report.

[0320] In some embodiments, the second information includes at least one of the following: the sequence number of the first Transmission Configuration Indication (TCI) state; and the index of the Control Resource Set Pool.

[0321] In some embodiments, the second information includes the sequence number of the first TCI state, which includes at least one of the following: an indicated first TCI state, which includes an indicated joint first TCI state or an indicated downlink first TCI state; and an activated first TCI state, which includes an activated joint first TCI state or an activated downlink first TCI state.

[0322] In some embodiments, the indicated joint first TCI state and / or the activated joint first TCI state are used to determine at least one of the following: Physical Downlink Control Channel (PDCCH); Physical Downlink Shared Channel (PDSCH); Physical Uplink Control Channel (PUCCH); Physical Uplink Shared Channel (PUSCH); Channel State Information Reference Signal (CSI-RS); Quasi-co-location QCL assumption of Probe Reference Signal (SRS); and / or, the indicated downlink first TCI state and / or the activated downlink first TCI state are used to determine at least one of the following: QCL assumption of PDCCH; PDSCH; CSI-RS.

[0323] In some embodiments, the first information is used to determine the second information corresponding to the first reference signal resource set, including: the first information explicitly indicating the correspondence between the first reference signal resource set and the second information; or, the first information includes at least two information fields, different first reference signal resource sets are contained in different information fields, and different information fields correspond to different second information.

[0324] In some embodiments, the transceiver module 6101 is further configured to: receive third information; the third information is configured to: activate one or more first TCI states corresponding to each of at least one code point, wherein the code point includes the code point corresponding to the indication field in the downlink control information (DCI); indicate the sequence number corresponding to the activated first TCI state; and indicate the index of the control resource set pool.

[0325] In some embodiments, the transceiver module 6101 is further configured to: in the event that the measurement result of the second reference signal resource satisfies the event, or in the event that the measurement result of the first reference signal resource and the measurement result of the second reference signal resource satisfy the event, the terminal sends fourth information and / or fifth information; wherein the fourth information is used to inform the network device terminal that there is a report to be sent; wherein the fifth information includes the report.
