Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, and particularly relates to a message processing method and device, a terminal device, a network device and a storage medium. BACKGROUND

[0002] In the NR (New Radio) system, when transmission is performed using a high frequency band, physical channels and physical signals can use beamforming technology to improve the transmission quality of data. Through the beamforming technology, the network device side can concentrate the transmission power to a certain direction (for example, the direction of the terminal) to increase the power of the received signal. However, when the link between the network device side and the terminal is blocked, the received power of the terminal side will be greatly reduced, thereby causing a (beam) transmission failure event. The NR system defines a beam failure recovery mechanism, also called a link recovery mechanism. The specific method is that the terminal reports to the network device side after detecting a transmission failure event, and then the network device side changes the service beam for the terminal to ensure normal transmission.

[0003] In the NR system, the network device side configures or defines a set of beam failure detection reference signals (BFD RS) for each service cell of the terminal. When the received power of all reference signals contained in the set is lower than a certain threshold, the terminal will send a beam failure recovery request to the network device side. The terminal will carry the cell index information in the beam failure request, and if the terminal side identifies a new available beam, the new beam related information can also be included in the beam failure recovery request. After receiving the beam failure recovery request sent by the terminal, the network device side will notify the terminal that a new service beam has been changed for it in a specific search space.

[0004] When a cell contains multiple transmission points (TRPs) and the link quality between one of the TRPs and a terminal is poor, the terminal will not report a beam failure event if the control channel of the other TRP can still work normally (i.e., the measurement value of part of the RS in the BFD RS set is higher than a certain threshold). However, for the transmission point with poor link quality, normal communication between it and the terminal cannot be guaranteed. The terminal can only wait until the link quality between all TRPs and the terminal becomes poor to start the beam failure recovery mechanism, or wait until the link quality between the failed TRP and the terminal is restored to normal to communicate normally. In this way, the data transmission on the TRP with poor link quality will have a large transmission delay. In addition, although multiple TRPs can provide services for the terminal, the TRP is invisible to the terminal, and the TRP is different from the cell and has no TRP index, so the existing cell beam failure mechanism cannot be directly extended to the TRP beam recovery mechanism. In addition, the existing network device side response mechanism will also make the terminal unable to determine which TRP is to be recovered, and thus the service beam determined by the terminal and the service beam actually used by the network device side are inconsistent, thereby causing transmission failure. SUMMARY

[0005] Embodiments of the present application provide a message processing method and device, a terminal device, a network device and a storage medium, to solve the problem that the existing technology cannot recover a new beam for a TRP in time when the link quality between the TRP and a terminal is poor.

[0163] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0164] As described in the background section, in the NR (new radio) system, when using high frequency bands for transmission, physical channels and physical signals can use beamforming technology to improve the transmission quality of data. Through the beamforming technology, the network device side can concentrate the transmission power to a certain direction (for example, the direction of the terminal) to increase the received signal power. However, when the link between the network device side and the terminal is blocked, it will cause the received power of the terminal side to be greatly reduced, and then cause the (beam) transmission failure event. The NR defines a beam failure recovery mechanism, also called a link recovery mechanism. The specific method is that the terminal reports to the network device side after detecting the transmission failure event, and then the network device side changes the service beam for the terminal to ensure normal transmission.

[0165] In the NR system, the network device side configures or predefines a set of beam failure detection reference signal (BFD RS) for each service cell of the terminal. When the received power of all reference signals contained in the set is lower than a certain threshold, the terminal will send a beam failure recovery request to the network device side. The terminal will carry the cell index information in the beam failure request, and if the terminal side identifies a new available beam, it can also include the new beam related information in the beam failure recovery request. After receiving the beam failure recovery request sent by the terminal, the network device side will notify the terminal that it has changed a new service beam for it in a specific search space.

[0166] When a cell contains multiple transmission points (TRPs) and the link quality between one of the TRPs and the terminal is poor, the terminal will not report a beam failure event if the control channel of the other TRP can still work normally (i.e., the measurement value of part of the RS in the BFD RS set is higher than a certain threshold). However, for the transmission point with poor link quality, normal communication between it and the terminal cannot be guaranteed. The terminal can only wait until the link quality between all TRPs and the terminal becomes poor to start the beam failure recovery mechanism, or wait until the link quality between the failed TRP and the terminal is restored to normal communication. In this way, the transmission delay of data transmission on the TRP with poor link quality will be large. In addition, although multiple TRPs can provide services for the terminal, the TRP is invisible to the terminal, and the TRP is different from the cell and has no TRP index, so the existing cell beam failure mechanism cannot be directly extended to the beam recovery mechanism of the TRP. In addition, using the existing network device side response mechanism will also make the terminal unable to determine which TRP is to be recovered, and thus the service beam determined by the terminal and the service beam actually used by the network device side will be inconsistent, thereby causing transmission failure. Based on this, the embodiments of the present application propose a beam failure recovery reporting and response method based on a single transmission point TRP, so that the network device side and the terminal determine the specific information of the TRP where the transmission failure occurs and the correspondence between the TRP to be recovered and the new candidate beam. In this application, beam failure can also be transmission failure, link failure between TRP and terminal, and failure can also be invalid. In the following description, the various descriptions and their meanings can be replaced with each other.

[0167] Specifically, the present application proposes a reporting and response method supporting transmission point transmission failure, aiming at the problem that the terminal cannot report in time when the channel corresponding to a single transmission point fails, and the network device side cannot replace the service beam in time. The terminal carries an index value related to the TRP in the transmission of the media access control control element (MAC CE, media access control, control element), the physical uplink control channel (PUCCH, physical uplink control channel), the physical random access channel (PRACH, physical random access channel), etc., and receives the recovery response of the TRP on the physical resource related to the TRP. So that the network device side and the terminal have a common understanding of the TRP to be recovered, and avoid the mismatch between the TRP and the new service beam. The message processing method, device, terminal device, network device and storage medium provided by the present application will be explained and described in detail below through specific embodiments.

[0168] It should be noted that in the following description, since the method and the device are based on the same application concept, the principles of solving problems of the method and the device are similar, and therefore the implementation of the device and the method can be referred to each other, and the repeated parts will not be described again.

[0174] The application will be described in detail below.

[0175] As shown in the step flow chart of the message processing method applied to a terminal device provided by an embodiment of the application, the method comprises the following steps: Figure 1

[0176] Step 101: sending a first signal to a network device; the first signal is used to indicate first index information of a link that has failed in beam.

[0177] In this embodiment, the terminal device sends a first signal (a beam failure recovery request signal) to the network device, which is used to indicate that the measurement value of one or more reference signals or a reference signal set of the network device meets a certain threshold, for example, assuming that PDCCH (bler) is greater than a threshold value (such as 10%), which indicates that the channel quality is poor.

[0178] In this embodiment, the first signal carries at least one of the following information (also called first index, also called TRP related index):

[0179] A beam failure detection reference signal (BFD RS) index corresponding to the link that has failed in beam;

[0180] A beam failure detection reference signal (BFD RS) set index corresponding to the link that has failed in beam;

[0181] A control resource set (CORESET) subset index corresponding to the link that has failed in beam;

[0182] A CORESET index corresponding to the link that has failed in beam;

[0183] A value of a CORESET high-level parameter CORESETPoolIndex corresponding to the link that has failed in beam;

[0184] A beam failure recovery (BFR) process index corresponding to the link that has failed in beam.

[0185] ​In the embodiment, it is to be noted that if the first signal is MAC CE signaling, the MAC CE signaling carries the BFR process index or CORESET subset index or BFD RS index or BFD RS set index,

[0186] In addition, in the embodiment, the MAC CE signaling can also include the failed cell index and the new beam index.

[0187] In addition, in the embodiment, the MAC CE signaling can indicate the index information and / or the cell index by bitmap or direct indication.

[0188] In addition, in the embodiment, the MAC CE signaling can only indicate the BFR process index and does not indicate the cell index.

[0189] In addition, in the embodiment, the MAC CE signaling can indicate the cell index and at most N BFR process indexes in one cell.

[0190] In addition, in the embodiment, the MAC CE signaling can indicate the failure indication corresponding to all BFD RS sets in the cell and / or the failure indication corresponding to part (such as one or more) of the BFD RS sets.

[0191] In addition, in the embodiment, if the first signal is SR resource, the period and offset of one SR indicate one BFR process index or CORESET subset index or BFD RS index or BFD RS set index.

[0192] In addition, in the embodiment, if the first signal is PRACH, the transmission resource indicates one BFR process index or CORESET subset index or BFD RS index or BFD RS set index.

[0193] The message processing method provided by the embodiment can be used for a terminal device to send a first signal to a network device, and the first signal is used to indicate first index information of a link in which beam failure occurs, so that the network device can be informed of which link has beam failure, and the terminal device can determine which link (TRP) the network device replaces the service beam of, and then the transmission of the single link (TRP) in which beam failure occurs can be recovered in time.

[0194] Based on the content of the above embodiment, in the embodiment, the first signal includes any one or more of the following information:

[0195] A beam failure detection reference signal (BFD RS) index corresponding to the link experiencing beam failure;

[0196] A BFD RS set index corresponding to the link experiencing beam failure;

[0197] A control resource set (CORESET) subset index corresponding to the link experiencing beam failure;

[0198] A CORESET index corresponding to the link experiencing beam failure;

[0199] A value of a CORESET higher layer parameter CORESETPoolIndex corresponding to the link experiencing beam failure;

[0200] A beam failure recovery (BFR) procedure index corresponding to the link experiencing beam failure.

[0201] Based on the content of the above embodiments, in this embodiment, the first signal is sent to the network device, including:

[0202] The first signal is sent to the network device through one or more of high layer signaling, a medium access control layer control element (MAC CE), a scheduling request (SR) resource, and a physical random access channel (PRACH).

[0203] Based on the content of the above embodiments, in this embodiment, when the SR resource is used to send the first signal, different links experiencing beam failure correspond to different SR resources.

[0204] Based on the content of the above embodiments, in this embodiment, when the SR resource is used to send the first signal, different links experiencing beam failure correspond to different SR resources, including:

[0205] When the SR resource is used to send the first signal, a period and an offset of one SR indicate one first index information.

[0206] Based on the content of the above embodiments, in this embodiment, when the MAC CE is used to send the first signal, the following at least one method is further included: a first index information and / or a cell index is indicated by a bitmap or a direct indication method;

[0207] The BFR procedure index is indicated, and the cell index is not indicated;

[0208] The cell index and at most N BFR procedure indexes in one cell are indicated;

[0209] A bitmap of beam failure indications corresponding to all BFD RS sets in a cell is indicated;

[0210] Indicates the beam failure indication corresponding to one or more BFD RS sets.

[0211] Based on the content of the above embodiment, in this embodiment, when the first signal is sent using PRACH, the transmission resource of the PRACH carries the first index information, or different PRACH transmission resources correspond to different first index information.

[0212] In the above embodiment, it should be noted that in order to support TRP beam failure recovery, the network device side can configure multiple SR resources for the terminal, and different types of SR resources have different period values ​​and offset values.

[0213] For example, the network device configures two types of SR resources for the terminal, each resource corresponding to a different TRP index. The network device can jointly determine the cell or TRP where the failure occurred through the SR resource and MAC CE signaling sent by the terminal. If the SR resource carries TRP-related index information and the MAC CE signaling carries cell ID-related information, the network device side jointly determines the cell and / or TRP where the failure occurred through the SR resource and MAC CE signaling.

[0214] Alternatively, SR resources can be used to carry partial grouping information, and MAC CE signaling can be used to carry intra-group information. For example, all BFR processes can be divided into three large groups, with SR resources carrying group number information and MAC CE carrying intra-group BFR process numbers. This can also reduce MAC CE signaling overhead. This embodiment does not limit the specific grouping method.

[0215] Similarly, TRP-related index information can also be carried in the PRACH channel transmission. For example, the resources for the preamble transmission are associated with the TRP-related index information in the first embodiment. The network device can determine which TRP has failed to transmit based on the resources used for the PRACH transmission.

[0216] like Figure 2 FIG. 1 is a flowchart of another message processing method applied to a terminal device side provided by an embodiment of the present application, the method comprising the following steps:

[0219] The first physical channel is a link where beam failure occurs or a channel corresponding to the beam failure recovery request signal.

[0220] In this embodiment, the terminal receives the second signal (the response signal sent by the network device to the terminal after receiving the beam failure recovery request) sent by the network device side, and determines the TCI (transmission configuration indication) state of the first physical channel associated with the second signal.

[0221] In this embodiment, the second signal and the first physical channel or the first reference signal are associated with at least one of the following indexes: BFD RS index, BFD RS set index, CORESET subset index, CORESET index, CORESET high layer parameter value, BFR process index.

It can be seen that the message processing method provided in the embodiments of the present application enables the terminal device to determine which service beam of which link (TRP) is replaced by the network device, and further enables the transmission of the single link (TRP) in which the beam failure occurs to be recovered in time.

[0234] Based on the content of the above embodiments, in the embodiment, determining the transmission configuration indication state of the first physical channel according to the second signal comprises:

[0242] Based on the content of the above embodiment, in the present embodiment, if the first physical channel is a physical downlink control channel PDCCH, the CORESET used for transmitting the second signal and the CORESET used for transmitting the first physical channel have the same CORESET high layer parameter or are associated with the same first index information; or,

[0243] If the first physical channel is a physical uplink control channel PUCCH, the CORESET receiving the second signal and the CORESET where the PDCCH indicating the resource of the first physical channel is located have the same CORESET high layer parameter or are associated with the same first index information; or,

[0255] Step a: sending a first signal to a network device;

[0256] Step b: receiving a second signal sent by the network device; wherein the second signal is a signal sent by the network device after receiving a beam failure recovery request signal (which can be understood as the first signal) for a link from a terminal device;

[0276] like Figure 4 FIG. 1 is a flowchart of another message processing method applied to a network device side according to an embodiment of the present application, the method comprising the following steps:

[0277] Step 401: Sending a second signal to a terminal device, so that the terminal device determines a transmission configuration indication (TCI) state and / or power control parameters of a first physical channel based on the second signal; wherein the second signal is a signal sent by the network device after receiving a beam failure recovery request signal from the terminal device for a link;

It can be seen that the message processing method provided in the embodiment of the present application enables the terminal device to determine which link (TRP) service beam is replaced by the network device, thereby realizing timely recovery of its transmission when a beam failure occurs in a single link (TRP).

[0280] Based on the content of the above embodiment, in this embodiment, sending a second signal to a terminal device so that the terminal device determines the transmission configuration indication TCI state and / or power control parameters of the first physical channel according to the second signal includes:

[0281] The terminal device sends a second signal, so that the terminal device determines a first physical channel corresponding to the second signal according to an association relationship between a resource carrying the second signal and first index information of a link in which beam failure occurs, and determines a transmission configuration indication state for the first physical channel.

[0282] Based on the content of the above embodiment, in the present embodiment, the second signal includes at least one of the following features:

[0285] The second signal contains an information field for indicating the first index information.

[0286] The second signal is a downlink control information DCI with the same number of hybrid automatic repeat request HARQ processes and a new data indicator NDI field that is flipped as an uplink physical shared channel PUSCH that schedules a beam failure recovery request.

[0287] The present application will be specifically described below through specific embodiments.

[0288] First embodiment:

[0289] The network device side will configure a BFD RS set or multiple BFD RSs for each TRP, or the terminal can determine a BFD RS set or multiple BFD RSs corresponding to one TRP according to a predefined method. When the terminal detects that the measurement values of all BFD RSs corresponding to one TRP meet the beam failure condition, it will trigger a beam failure recovery report, requesting the network device to replace the service beam (TCI state) for it and restore normal transmission. The measurement values of all BFD RSs corresponding to one TRP meeting the beam failure condition can be one or more reference signals in the BFD RS set, or all reference signals in the reference signal set meeting a certain threshold (for example, assuming that the block error rate BLER is higher than 10%), all reference signals in the reference signal set meeting a certain threshold, that is, the measurement value of the reference signal set meeting a certain threshold.

[0290] It should be noted that the TRP-related information carried in the beam failure recovery report can have the following forms:

[0291] BFD RS related index associated with TRP, for example, BFD RS set index, BFD RS index or other forms of BFD RS grouping index;

[0292] CORESET related index associated with TRP, for example, CORESET index or CORESET configuration related index (such as the value of high layer parameter CORESETPoolIndex configured under CORESET) or CORESET subset index. CORESET index is the CORESET ID (controlResourceSetId) configured by high layer parameter, for example, the terminal can determine the association between each TRP and CORESET through the configuration of the network device side or in a predefined manner, such as high layer signaling configuration TRP1 is associated with CORESET 1, 2, 3, and TRP2 is associated with CORESET 4, 5. The terminal only needs to carry the index of one of the multiple CORESETs associated with one TRP when reporting, for example, the CORESET index with the lowest number, the index with the highest number, or any CORESET index. CORESET subset index is the index of a group or a subset of CORESET grouping. After obtaining the CORESET related index information reported by the terminal, the network device side can determine which TRP has a beam failure.

[0293] It can also be the index of the BFR (beam failure recovery) process explicitly configured or determined by the network device side. The BFR process is used by the terminal to determine the number of beam failure detection processes in a cell. Each BFR process can correspond to one or more TRPs, or a cell, or a BFD RS set, a CORESET subset, one or more CORESET, etc.

[0294] In all embodiments of the present application, the description related to TRP can be replaced by the above TRP related index, including BFD RS related index, CORESET related index or BFR process index, etc.

[0295] In the present application, the beam failure recovery report sent by the terminal can also be referred to as beam failure recovery request or first signal.

[0296] Second embodiment:

[0297] The TRP related information in the first embodiment can be carried by the following signals or channels:

[0298] MAC CE signaling, the BFD RS related index corresponding to the TRP pair that can fail in the signaling, the CORESET related index corresponding to the TRP pair, or the BFR process index corresponding to the TRP pair or cell, etc.

[0299] The MAC CE signaling for indicating beam failure in the current protocol is as shown in Figure 5 , which represents the case where the number of configured cells available for beam failure recovery is less than 8 (the case where it is greater than 8 is similar, and Ci takes a maximum value of 31). Wherein Ci (i = 1, 2, …, 7) corresponds to different cells respectively, when Ci is set to 1, it indicates that beam failure occurs in the corresponding cell, and when it is set to 0, it indicates that no beam failure occurs.

[0300] If TRP related information is added, it is not accurate to indicate whether beam failure occurs in a cell only by using bitmap. One approach is to add TRP indication for each cell based on the bitmap indication of each cell, that is, to add P indication fields for each cell, which respectively correspond to P TRPs, for example Figure 6 , as shown (taking P = 2 TRPs as an example), the number of P is the same as the number of TRP related indexes configured for each cell (i.e. the BFD RS set index, CORESET subset index, BFR process index, etc. in the first embodiment). When Ci = 0, it indicates that all BFD RS set indexes, BFR process indexes, CORESET subset indexes, etc. in the cell do not have transmission failure, when Ci = 1, it indicates that all BFD RS set indexes, BFR process indexes, CORESET subset indexes, etc. in the cell have transmission failure, and the specific one that has failure also depends on the bitmap value of Tj. Similarly, Tj = 1 indicates that the transmission of the corresponding TRP related physical resource has failed, and Tj = 0 indicates that the transmission of the corresponding TRP related physical resource has not failed. The terminal does not expect Ci = 1 and all Tj values associated with it to be 0; similarly, the terminal does not expect Ci = 0 and there is a case where Tj value is 1.

[0301] When the number of cells and the number of TRPs are both high, the MAC CE signaling indication will increase the signaling overhead. Other ways can also be used for indication, for example, not through bitmap, but through Figure 7 signaling form to indicate the failed cell and / or TRP to the network device. The terminal does not need to indicate all cells to the network device, but only the failed cell and / or TRP. Wherein TRP ID is the TRP related index (such as BFD RS set index, CORESET subset index, BFR process index, etc.) in the first embodiment

[0302] In addition to the above several indication methods, the network device side can also configure the total number of BFR processes, and the network device side can indicate the BFR process according to the total number of BFR processes. For example, the network device side configures 16 cells, some cells contain only one BFR process, some cells contain 2 or 3 BFR processes, and the total number of BFR processes is 32. The network device side can indicate the BFR process in the MAC CE signaling by using a bitmap, as shown in FIG. 6. Figure 8 Similarly, Pt (t = 0, 1, …, 31) is equal to 1, indicating that the corresponding BFR process has a transmission failure, and Pt = 0 indicates that the corresponding BFR process has no failure.

[0303] The network device side can also transmit the TRP-related index information (BFD RS set index, CORESET subset index, BFR process index, etc. in the first embodiment) on the PUCCH channel through the SR (scheduling request) resource. In the existing beam failure recovery, only one SR resource (configured by high-layer signaling schedulingRequestID-BFR-SCell-r16) is used to indicate the failure event and apply for the corresponding uplink transmission resource to further report the MAC CE signaling. The SR resource has a specific period and offset configuration, and the terminal can use the configuration to determine any one of a group of SR resources to report the failure event. To support TRP beam failure recovery, the network device side can configure multiple SR resources for the terminal, and different types of SR resources have different period values and offset values.

[0304] For example, the network device configures two SR resources for the terminal, each resource corresponding to a different TRP index, and the network device can determine the failed cell or TRP through the SR resource and the MAC CE signaling sent by the terminal. For example, the SR resource carries the TRP-related index information, and the MAC CE signaling carries the cell ID-related information, and the network device side determines the failed cell and / or TRP through the SR resource and the MAC CE signaling.

[0305] The SR resource can also carry part of the group information, and the MAC CE signaling can carry the information in the group. For example, all BFR processes are divided into three groups, the SR resource carries the group number information, and the MAC CE carries the BFR process number in the group (such as using the signaling format of FIG. 7). In this way, the overhead of the MAC CE signaling can also be reduced. The specific grouping manner is not limited in the embodiment. Figure 8

[0306] ​Similarly, the TRP-related index information can also be carried in the PRACH channel transmission. For example, the resources used for the preamble transmission and the TRP-related index information in the first embodiment are associated. The network device can determine which TRP has a transmission failure according to the resources used for the PRACH transmission.

[0307] Third embodiment:

[0308] In the prior art, each cell is configured with a BFR-related search space for receiving the response information from the network device after sending the beam failure recovery request (BFRQ). After receiving the response information from the network device, the terminal considers that the network device has received the BFRQ sent by the terminal and has replaced the service beam for it. In addition, the response sent by the network device is the DCI signaling scrambled by the C-RNTI (Cell-Radio Network Temporary Identifier) or MCS-C-RNTI (Modulation and Coding Scheme-Cell-Radio Network Temporary Identifier).

[0309] If a cell contains multiple TRPs, the beam failure recovery of the TRP or the cell uses the search space configured in the prior art to receive the response from the network device. In particular, when more than one TRP has a beam failure, the terminal cannot determine which TRP has a beam failure event through the received response information. If the response information sent by the network device is misunderstood, i.e., for a failed TRP, the terminal considers that the network device has replaced the service beam for it, and will not report the BFRQ again, causing the beam failure event of the TRP to be unable to be recovered in time. Therefore, it is necessary to modify the existing response information receiving method to support TRP-level beam failure recovery. In this application, the response information is also referred to as the second information.

[0310] The specific method can be:

[0311] In the first embodiment, the network device configures more than one dedicated search space or CORESET for receiving the response information on the network device side, and each search space or CORESET is associated with a TRP-related index (a BFD RS set index, a CORESET subset index, a BFR process index, etc.). For example, the network device configures two search spaces, and the two search spaces are respectively associated with two CORESETs with different values of the high-level parameter CORESETPoolIndex. When the terminal receives the response information in the search space of the CORESET with the value of CORESETPoolIndex being 0, it indicates that the transmission corresponding to the group of CORESETs (or a CORESET subset) with the value of CORESETPoolIndex being 0 fails. Similarly, when the terminal receives the response information in the search space of the CORESET with the value of CORESETPoolIndex being 1, it indicates that the transmission corresponding to the group of CORESETs (or a CORESET subset) with the value of CORESETPoolIndex being 1 fails. The above example is only illustrative, and other embodiments can also be used. For example, when the TRP1 fails, the terminal can also receive the response information in the CORESET or search space related to the TRP2. For example, when the terminal detects that the transmission corresponding to the TRP1-related index fails, it can receive the response in the CORESET or search space corresponding to the TRP2-related index after sending the BFRQ, so as to increase the probability of correct transmission of the response information. The present embodiment is not limited to the above embodiments. In addition, the dedicated CORESET or search space refers to a CORESET that is not configured with other search spaces in addition to the search space used for receiving the response (the high-level parameter recoverySearchSpaceId), so as to avoid the terminal from incorrectly understanding the response information on the network device side. If the terminal is configured to use two or more CORESETs or search spaces to receive the response information on the network device side, the terminal can use a new candidate beam corresponding to the CORESET or search space to receive the response information after a certain number of time slots after sending the BFRQ. The new candidate beam refers to that, when the terminal receives the response to the transmission failure of the TRP1, it uses a new candidate beam of the TRP1 (regardless of whether the response information is received in the CORESET or search space related to the TRP1 or the CORESET or search space related to the TRP2), and similarly, when the terminal receives the response to the transmission failure of the TRP2, it uses a new candidate beam of the TRP2.

[0312] ②The network device can also receive the response information in a non-dedicated CORESET or search space. Similar to the dedicated CORESET or search space method in 1), two or more CORESETs or search spaces are used to receive the response information of two TRPs. Here, no further description is given, but the CORESET or search space can also receive the reception of other DCI in addition to the response signal. In order to further distinguish the response information and other DCI information, the response information needs to satisfy a predetermined time interval with the BFRQ transmission time. For example, the response information received within K time slots of the TRP1-related BFRQ information transmission is about the beam failure recovery of TRP1; the response information received within K time slots of the TRP2-related BFRQ information transmission is about the beam failure recovery of TRP2, and so on.

[0313] ③In addition, a field can be added to the response information (DCI signaling) sent by the base station to indicate which TRP the response information is for, for example, the information field contains 1 bit, which is used to indicate the CORESET subset index (such as the value of the higher layer parameter CORESETPoolIndex, 0 or 1, or the BFR process index 0 or 1); it can also contain 2 bits, which are used to indicate more than 2 BFR process numbers (such as the supported BFR process index up to 3, including 0, 1, 2, 3); it can also be more than 2 bits, containing CORESET ID or BFD RS set index, etc. The present embodiment does not limit the number of bits and the combination of TRP-related indexes contained, that is, each bit width of the information field can be combined with the TRP-related index (including the BFD RS set index, CORESET subset index, BFR process index in the first embodiment).

[0314] It should be noted that the BFRQ information can be a preamble sent by the terminal on the PRACH channel, an SR sent on the PUCCH channel, a MAC CE signaling sent on the PUSCH channel, etc. The received response information (i.e., DCI signaling) can be DCI signaling with CRC scrambled by C-RNTI or MCS-C-RNTI sent by the terminal after receiving the BFRQ, and can also be DCI signaling scheduling and sending the MAC CE signaling with the same HARQ (Hybrid automatic repeat request) process number and the flipped NDI (new data indicator) field value (i.e., indicating that the network device side has received the MAC CE signaling sent by the terminal).

[0315] Fourth embodiment:

[0316] In the existing protocol, the terminal uses the new candidate beam for all CORESETs in a cell to monitor PDCCH and uses the new candidate beam corresponding to the cell for PUCCH transmission after receiving the response of 28 symbols on the network device side. After introducing the beam failure recovery mechanism of multi-TRP, different PDCCH or PUCCH may correspond to different TRP, and it is unreasonable to use the new candidate beam reported by the terminal. For example, beam failure occurs in TRP1, and the terminal reports the new beam (TCI state) used for transmission of TRP1. If both TRP1 and TRP2 transmissions use this new beam, it will cause poor transmission quality or even failure of TRP2. Therefore, it is necessary to improve the physical channel TCI setting or determination method in the existing protocol to adapt to the beam failure recovery in the multi-TRP scenario.

[0317] After receiving the response of the network device side, the terminal replaces the service beam of the physical channel associated with the response information with a suitable new candidate beam after T time slots (slots) or symbols, and the physical channel unrelated to the response information does not need to replace the service beam, that is, the association relationship between the response information, the physical channel (including PDCCH, PUCCH, PUSCH, PDSCH, PRACH, etc., which can be called the first physical channel) and the new candidate beam is introduced. Obviously, the response information, the physical channel and the new candidate beam associated with a TRP are associated, however, since the TRP is invisible to the terminal, an other parameter or physical resource or index value (such as the TRP-related index (BFD RS index, BFD RS set index, CORESET subset index, CORESET index, CORESET high-layer parameter value, BFR process index, etc.) in the first embodiment, or the dedicated CORESET or the information carried by the response information in the third embodiment) is needed to associate them.

[0318] Association between the first physical channel and the response signal (second signal):

[0319] If the first physical channel is PDCCH, the CORESET used for transmitting the first physical channel is associated with the CORESET receiving the second signal if they have the same CORESET-related index value (such as CORESET subset index, CORESET index, CORESET high-layer parameter value). After receiving the second signal sent by the network device, the terminal uses the new candidate beam (TCI state, QCL parameter reference signal index q new of the CORESET where the second signal is transmitted.

[0320] If the first physical channel is PUCCH, the CORESET used by the PDCCH transmission indicating the resource of the first physical channel is associated with the CORESET receiving the second signal if they have the same CORESET-related index value (e.g., CORESET subset index, CORESET index, CORESET higher layer parameter value). After receiving the second signal sent by the network device side, the terminal transmits the first physical channel associated with it using the new candidate beam (TCI state, QCL parameter of reference signal index q new .

[0321] If the first physical channel is PDSCH / PUSCH, the CORESET used by the PDCCH transmission scheduling it is associated with the CORESET receiving the second signal if they have the same CORESET-related index value (e.g., CORESET subset index, CORESET index, CORESET higher layer parameter value). After receiving the second signal sent by the network device side, the terminal receives or transmits the first physical channel associated with it using the new candidate beam (TCI state, QCL parameter of reference signal index q new .

[0322] In the present embodiment, it should be noted that the determination method of the new candidate beam (TCI state, QCL parameter of reference signal index q new .

[0323] The TCI state of the first physical channel can be the TCI state carried in the first signal sent by the terminal to the network device side or the QCL parameter of the first reference signal. After receiving the response signal (second signal) from the network device side, the terminal can apply the TCI state or the QCL parameter to the first physical channel when it carries the new candidate beam information (TCI state or QCL parameter) when sending the first signal.

[0324] It should be noted that, in addition, the new candidate beam can also be determined according to the association relationship between the new candidate beam and the TRP-related index or the first signal or the response signal (second signal).

[0325] For example, when the terminal sends the first signal to the network device side, it will carry the TRP-related index (BFD RS index, BFD RS set index, CORESET subset index, CORESET index, CORESET higher layer parameter value, BFR process index, etc.) and the new candidate beam information (if the terminal can detect it), so the terminal can determine the association relationship between the new candidate beam and the TRP-related index.

[0326] The associated power control parameters of the first channel can also be determined in a similar manner as the TCI state, and the first channel is associated with the second signal or the failed link (TRP). The power parameters include the path loss parameters, open-loop power control parameters, etc.

[0327] According to the method of the third embodiment, the network device side can carry the TRP-related index in the response signal (second signal), for example, send the second signal in the TRP-related CORESET or search space, or directly indicate the TRP-related index in the second signal, etc. Alternatively, the terminal can determine the association between the second signal and the first signal (the first signal carries new candidate beam information) according to the number of HARQ processes and / or NDI values indicated in the second signal. Therefore, after receiving the second signal, the terminal can also determine the association between the second signal and the new candidate beam, and then apply the associated new candidate beam to the associated first physical channel.
