Description

Technical Field

[0001] The present application relates to the field of wireless communications, and in particular to an information reporting method, apparatus, related equipment and storage medium. Background Art

[0002] In the related technology, a primary cell (PCell) beam failure recovery process is proposed, which mainly includes: Step 1: the terminal detects beam failure; Step 2: the terminal identifies the alternative beam; Step 3: the terminal sends a beam recovery request (BFRQ, Beam Failure Recovery Request) to the base station; Step 4: the terminal monitors the base station's response to BFRQ.

[0003] The process of detecting beam failure by the terminal includes: the terminal detects the quality of RS in the reference signal (RS) set q0, wherein q0 is configured by the base station or determined according to the transmission configuration indicator state (TCI-state) of the control resource set (CORESETs); when the quality of all RS in q0 is lower than Qout,LR, a beam failure instance is counted, and when the number of beam failure instances exceeds the defined number within a certain period of time, it is determined that a beam failure has occurred. The terminal identifies the alternative beam by selecting the RS whose reference signal received power (RSRP) is greater than or equal to Qin,LR in the reference signal set q1. Sending BFRQ means: sending RS information related to the alternative beam on the corresponding physical random access channel (PRACH) resource, and the base station can obtain the corresponding alternative beam information after receiving PRACH.

[0004] In the related technology, the beam failure recovery process of the secondary cell (SCell) is also introduced. The difference from the beam failure recovery process of the PCell is that after the user equipment (UE) detects the beam failure, it reports the SCell ID where the beam failure occurred in the media access control (MAC) control unit (CE). In addition, when the UE identifies the alternative beam, it also reports the alternative beam RS information.

[0005] In related technologies, multi-transmission receiving point (multi-TRP) technology is also introduced, that is, a terminal can establish communication links with multiple TRPs for data transmission, and multiple TRPs can improve the transmission reliability or transmission rate by sending the same or different data. Figure 1As shown, assuming that TRP1 and TRP2 belong to the same cell, according to the beam failure detection mechanism in the related art, the base station configures a reference signal set q0 for detecting the link quality of TRP1 and TRP2. When the quality of all reference signals in q0 is lower than Qout,LR, a beam failure instance is counted. However, in the multi-TRP scenario, it may happen that the link between the terminal and only one TRP is blocked (blockage). For example, TRP1 cannot communicate with the terminal, but TRP2 still maintains communication with the terminal. In this case, the beam of TRP1 can be restored and communication can continue through multi-TRP.

[0006] However, when multi-TRP technology is deployed in a carrier aggregation (CA) scenario, there is currently no effective solution for how to achieve beam failure recovery when multiple TRPs fail to send beams at the same time. Summary of the invention

[0055] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0056] When the multi-TRP technology is deployed in a CA scenario, taking two TRPs (TRP1 and TRP2) as an example, beam failure may occur in the following situations:

[0057] Case 1: Beam failure occurs in TRP1 or TRP2 of SCell;

[0058] Case 2: Beam failure occurs between TRP and TRP2 on the same component carrier (CC) of SCell;

[0059] Case 3: Beam formation failure occurs in TRP1 or TRP2 of PCell;

[0060] Case 4: Beam formation failure occurs in TRP1 and TRP2 of PCell;

[0061] The fifth case: beam failure occurs in TRP1 and TRP2 on different CCs in the PCell or the SCell capable of configuring physical uplink control channel (PUCCH) resources (which may be referred to as PUCCH-SCell).

[0062] In the related technology, a beam recovery process is proposed for the first and third cases, that is, when only one TRP has a beam failure, but when multiple TRPs fail to send beams at the same time (such as the second and fourth cases) (that is, all TRPs located on a Pcell or a CC fail to send beams at the same time), how to achieve beam failure recovery is a problem that needs to be solved urgently.

[0063] The present application embodiment provides an information reporting method, which is applied to a terminal, such as Figure 2 As shown, the method includes:

[0064] Step 201: Detect that link qualities corresponding to N first reference signal sets are lower than a first threshold; N is an integer greater than 1;

[0065] Step 202: Report first information to the network side; the first information includes M reference signal identifiers and second information; the second information represents whether the terminal can simultaneously receive M reference signals; M is an integer greater than or equal to 1, and M is less than or equal to N; the M reference signals come from M second reference signal sets.

[0066] Among them, the information reporting method provided in the embodiment of the present application can be understood as a beam failure request reporting method.

[0067] In step 201, N first reference signal sets correspond to N TRPs, that is, one first reference signal corresponds to one TRP. When the link quality corresponding to the N first reference signal sets is lower than the first threshold, it indicates that beam failure has occurred in the N TRPs.

[0068] In actual application, the terminal may be referred to as a UE or a user.

[0069] The value of the first threshold can be set as required. The first threshold can be configured by the network side.

[0070] The link qualities corresponding to the N first reference signal sets are lower than the first threshold, which means that the link qualities corresponding to each of the N first reference signal sets are lower than the first threshold.

[0071] Here, when the quality of all reference signals in each first reference signal set is lower than the first threshold, and when the number of times that the quality of all reference signals is lower than the first threshold exceeds a preset number within a certain period of time (which can be set as needed), it can be considered that the links corresponding to each first reference signal set are lower than the first threshold.

[0072] In actual application, the network side configures N first reference signal sets for the terminal, and can also configure P second reference signal sets, where P is an integer less than or equal to N, and M is less than or equal to P; wherein the N first reference signal sets correspond to the P second reference signal sets.

[0073] In step 202, the second reference signal set may also be referred to as a candidate reference signal set.

[0074] The M reference signal identifiers included in the first information means that the first information includes an identifier of each reference signal in the M reference signals.

[0075] In one embodiment, the quality of each reference signal in the M reference signals is greater than or equal to a second threshold, thus ensuring the validity of the candidate beams.

[0076] Here, in actual application, the quality of the reference signal may be layer 1-reference signal received power (L1-RSRP). The value of the second threshold may be set as required.

[0077] For the P second reference signal sets configured by the network side, the terminal may determine the reference signal to be reported according to whether the reference signal in each second reference signal set can be received simultaneously, which may specifically include the following situations:

[0078] In the first case, for P second reference signal sets, if the terminal measures (also referred to as detects) a reference signal whose L1-RSRP is greater than or equal to the second threshold from each second reference signal set, and the terminal can receive these reference signals simultaneously, the terminal reports the identifiers of the P second reference signals that can be received simultaneously. At this time, M is equal to P.

[0079] Exemplarily, taking two TRPs as an example, if the terminal detects that both TRPs fail in a certain CC, the terminal measures a reference signal with L1-RSRP greater than or equal to the second threshold in each of the second reference signal sets configured by the network side and associated with the two TRPs where beam failure occurs, and the terminal can receive these reference signals at the same time, the terminal reports the identifiers of the two reference signals with L1-RSRP greater than or equal to the second threshold.

[0080] In the second case, for P second reference signal sets, if the terminal measures a reference signal whose L1-RSRP is greater than or equal to the second threshold from each second reference signal set, and the terminal cannot receive these reference signals at the same time, the terminal reports the identifiers of these P second reference signals. At this time, M is equal to P.

[0081] Exemplarily, taking two TRPs as an example, if the terminal detects that both TRPs fail in a certain CC, if the terminal detects that both TRPs fail in a certain CC, the terminal measures a reference signal with L1-RSRP greater than or equal to the second threshold in each second reference signal set configured by the network side and associated with the two TRPs where beam failure occurs, but the terminal cannot receive these two reference signals at the same time, the terminal reports the identification of two reference signals with L1-RSRP greater than or equal to the second threshold.

[0082] In the third case, for P second reference signal sets, when reference signals whose L1-RSRP is greater than or equal to the second threshold are measured only from M (M is less than P, and M is greater than or equal to 2) second reference signal sets, and the terminal can receive these reference signals at the same time, the terminal reports the identifiers of these M second reference signals.

[0083] In the fourth case, for P second reference signal sets, if the terminal only measures reference signals with L1-RSRP greater than or equal to the second threshold from M (M is less than P, and M is greater than or equal to 2) second reference signal sets, and the terminal cannot receive these reference signals at the same time, the terminal reports the identifiers of the M second reference signals.

[0084] In a fifth case, for the P second reference signal sets, if the terminal measures only one reference signal whose L1-RSRP is greater than or equal to the second threshold from one second reference signal set, the terminal reports the identifier of the reference signal.

[0085] Exemplarily, taking two TRPs as an example, if the terminal detects that both TRPs fail in a certain CC, the terminal measures a reference signal with L1-RSRP greater than or equal to a second threshold from one of the second reference signal sets configured on the network side and associated with the two TRPs where beam failures occur. At this time, the terminal reports an identifier of a reference signal with L1-RSRP greater than or equal to the second threshold.

[0086] In the sixth case, for the P second reference signal sets, the terminal has not measured any reference signal whose L1-RSRP is greater than or equal to the second threshold from the P second reference signal sets. At this time, the terminal does not report the alternative beam reference signal, that is, does not send the first information.

[0087] In actual application, when at least two reference signals whose L1-RSRP is greater than or equal to the second threshold are measured in a second reference signal set, the terminal can select a reference signal as an alternative reference signal as needed for reporting to the network side, such as selecting a reference signal with the largest L1-RSRP from the at least two reference signals as the alternative reference signal.

[0088] In practical application, when M is equal to 1, the first information includes an identifier of a reference signal. When M is greater than or equal to 2, the first information includes M reference signal identifiers and the second information.

[0089] In one embodiment, the terminal may report the first information to the network side via MAC CE, so that it can be compatible with related technologies and is easy to implement.

[0090] The resource for sending the MAC CE may be a PUSCH resource or a PRACH resource, that is, the MAC-CE resource may be carried by a PUSCH scheduled by the network side or by a PRACH.

[0091] Based on this, in one embodiment, the MAC CE is carried through PUSCH or PRACH.

[0092] Among them, when the MAC CE is carried by PRACH, the first information can be reported through Msg 3 (applicable to four-step random access process) or Msg A (applicable to two-step random access process).

[0093] In actual application, when the terminal reports the first information through Msg 3, when message 4 (Msg4) is received, it is considered that the network side has successfully received the first information reported by the terminal, that is, the alternative beam information.

[0094] When the terminal reports the first information through Msg A, when message B (Msg B) is received, it is considered that the network side successfully receives the first information reported by the terminal.

[0095] When the network side successfully receives the first information reported by the terminal, the terminal can send information using the same spatial direction as at least one reference signal among the M reference signals (which can be a reference signal among the M reference signals that can be received simultaneously), and can also receive information using a DMRS that is quasi-co-located with at least one reference signal among the M reference signals.

[0096] Exemplarily, taking two TRPs as an example, if the terminal detects that both TRPs fail in a certain CC, when the terminal reports the identifiers of the two reference signals corresponding to the two TRPs whose L1-RSRP is greater than or equal to the second threshold, and the two reference signals can be received by the terminal at the same time, the terminal can use the same spatial direction as the two reference signals to send information, and can also use the DMRS that is quasi-co-located with the two reference signals to receive information, that is, it recovers to multi-TRP transmission.

[0097] When the terminal reports the identifiers of the two reference signals whose L1-RSRP corresponding to the two TRPs is greater than or equal to the second threshold, and the two reference signals cannot be received by the terminal at the same time, the terminal can use the same spatial direction as one of the two reference signals (the network side can decide which reference signal to use, and the network side uses the same direction as one of the reference signals to send information. The terminal receives information when it receives the DMRS that is quasi-co-located with the reference signal in space, and can know which reference signal to use), and can also use the DMRS that is quasi-co-located with one of the two reference signals in space to receive information, that is, restore to single TRP (single-TRP) transmission.

[0098] The spatial direction may also be referred to as beam direction.

[0099] Accordingly, the embodiment of the present application also provides an information reporting method, which is applied to a network device (specifically a base station), such as Figure 3 As shown, the method includes:

[0100] Step 301: The receiving terminal reports the first information after detecting that the link quality corresponding to N first reference signal sets is lower than the first threshold; N is an integer greater than 1; the first information includes M reference signal identifiers and second information; the second information represents whether the terminal can simultaneously receive M reference signals; M is an integer greater than or equal to 1, and M is less than or equal to N; the M reference signals come from M second reference signal sets.

[0101] In one embodiment, the network device receives the first information reported by the terminal through MAC CE.

[0102] Here, in one embodiment, the MAC CE is carried by PUSCH or PRACH.

[0103] In one embodiment, when the MAC CE is carried by PRACH, the first information is received through Msg3 or Msg A.

[0104] like Figure 3 As shown, the method may also include:

[0105] Step 302: Using the first information, restore the transmission to multi-TRP transmission or single-TRP transmission.

[0106] Specifically, the network device sends information using the same spatial direction as at least one reference signal among the M reference signals;

[0107] and / or,

[0108] The network device receives information using a DMRS that is quasi-co-located with at least one reference signal among the M reference signals.

[0109] More specifically, when M is equal to 1, the network device sends information according to the spatial direction corresponding to the reference signal identifier, and uses the DMRS that is quasi-co-located with the reference signal port space to receive information, that is, it recovers to single-TRP transmission. Exemplarily, taking two TRPs as an example, if the terminal detects that both TRPs fail in a certain CC, the terminal only reports an identifier of a reference signal whose L1-RSRP is greater than or equal to the second threshold. At this time, the network device uses the spatial direction corresponding to the reference signal identifier to send information, and uses the DMRS that is quasi-co-located with the reference signal port space to receive information.

[0110] When M is greater than 1, and none of the M reference signals can be received simultaneously by the terminal, the network device selects one reference signal from the M reference signals, sends information in the spatial direction corresponding to the selected reference signal identifier, and receives information using the DMRS that is quasi-co-located with the selected reference signal port space, i.e., restores to single-TRP transmission. Exemplarily, taking two TRPs as an example, if the terminal detects that both TRPs fail in a certain CC, the terminal reports the identifiers of two reference signals whose L1-RSRP is greater than or equal to the second threshold, but the two reference signals cannot be received by the terminal at the same time, at this time, the network device selects one reference signal from the two reference signals, sends information according to the spatial direction corresponding to the selected reference signal identifier, and receives information using the DMRS that is quasi-co-located with the selected reference signal port space.

[0111] Here, the network device may randomly select a reference signal from the M reference signals. The embodiment of the present application does not limit the specific processing procedure of selecting a reference signal from the M reference signals.

[0112] When M is greater than 1, and at least two of the M reference signals can be simultaneously received by the terminal, the network device can send information in the spatial directions corresponding to the at least two reference signal identifiers, and use the DMRS that is quasi-co-located with the at least two reference signal ports to receive information, that is, restore to multi-TRP transmission.

[0113] The present application also provides an information reporting method, such as Figure 4 As shown, the method includes:

[0114] Step 401: The terminal detects that the link quality corresponding to N first reference signal sets is lower than a first threshold; N is an integer greater than 1;

[0115] Step 402: The terminal reports first information to the network device; the first information includes M reference signal identifiers and second information; the second information indicates whether the terminal can simultaneously receive M reference signals; M is an integer greater than or equal to 1, and M is less than or equal to N; the M reference signals come from M second reference signal sets;

[0116] Step 403: The network device receives the first information.

[0117] Here, it should be noted that the specific processing process of the terminal and the network device has been described in detail above and will not be repeated here.

[0118] The information reporting method provided in the embodiment of the present application is that the terminal detects that the link quality corresponding to N first reference signal sets is lower than the first threshold; N is an integer greater than 1; the first information is reported to the network side; the first information includes M reference signal identifiers and second information; the second information represents whether the terminal can receive M reference signals simultaneously; M is an integer greater than or equal to 1, and M is less than or equal to N; the M reference signals come from M second reference signal sets, and the scheme of the embodiment of the present application is adopted to realize the reporting of beam failure information when multiple TRPs fail to send beams simultaneously, thereby realizing beam failure recovery, which is beneficial to reducing the beam recovery delay and improving the success rate of beam recovery.

[0119] In order to implement the method provided in the embodiment of the present application, the embodiment of the present application also provides an information reporting device, which is arranged on the terminal, such as Figure 5 As shown, the device comprises:
