Description

Information reporting method, device, related equipment and storage medium

Technical Field

The present application relates to the field of wireless communications, and in particular, to an information reporting method and apparatus, a related device, and a storage medium.

Background

In the related art, a primary cell (PCell) beam failure recovery procedure is proposed, which mainly includes: step 1: the terminal fails to detect the beam; and 2, step: the terminal identifies alternative beams; and 3, step 3: the terminal sends a Beam Recovery Request (BFRQ, beam Failure Recovery Request) to the base station; and 4, step 4: the terminal monitors the response of the base station to BFRQ.

The process that the terminal fails to detect the beam comprises the following steps: terminal detection Reference Signal (RS) set

The mass of the RS, wherein,

configured by a base station or determined according to a transmission configuration index status (TCI-state) of a control resource set (coreset); when the temperature is higher than the set temperature

When the quality of all the RSs in the set is lower than Qout and LR, counting a beam failure instance (beam failure instance), and when the number of times of the beam failure instance exceeds a defined number in a certain time length, determining that beam failure occurs. The terminal identifies the alternative beam to pick out the reference signal set

The Reference Signal Received Power (RSRP) is greater than or equal to the RS of Qin, LR. Sending BFRQ means: and transmitting the information of the alternative wave beam RS on a corresponding Physical Random Access Channel (PRACH) resource, and obtaining the information of the corresponding alternative wave beam after the base station receives the PRACH.

In the related art, a beam failure recovery procedure of a secondary cell (SCell) is also introduced, which is different from the beam failure recovery procedure of the PCell: after detecting the beam failure, the User Equipment (UE) reports the SCell id with the beam failure on a Media Access Control (MAC) control unit (CE), and in addition, when the UE identifies the alternative beam, the UE also reports the RS information of the alternative beam.

In the related art, a multi-Transmission receiving Point (multi-TRP) technology is also introduced, that is, a terminal may establish a communication link with multiple TRPs for data Transmission, and the multiple TRPs may improve Transmission reliability or Transmission rate by sending the same or different data. As shown in fig. 1, assuming that TRP1 and TRP2 belong to the same cell, according to a beam failure detection mechanism in the related art, a base station configures a reference signal set for detecting link quality of TRP1 and TRP2

When in use

When the quality of all reference signals is lower than Qout, LR, the beam failure instance is counted once. However, in a multi-TRP scenario, a situation may occur in which a link between a terminal and only a certain TRP is blocked (block), for example, TRP1 cannot communicate with the terminal, and TRP2 still communicates with the terminal, and this situation may recover a beam of TRP1 and continue to communicate through the multi-TRP.

However, when the multi-TRP technology is deployed in a Carrier Aggregation (CA) scenario, there is no effective solution for how to achieve beam failure recovery when multiple TRPs fail to transmit beams simultaneously.

Detailed Description

The present application will be described in further detail with reference to the following drawings and examples.

When the multi-TRP technology is deployed in the CA scenario, taking two TRPs (TRP 1 and TRP2, respectively) as an example, there may be several cases where a beam failure occurs:

in the first case: a beam failure occurs to TRP1 or TRP2 of the SCell;

in the second case, TRP and TRP2 on the same Component Carrier (CC) of the SCell fail to beam;

in the third case: a beam failure of TRP1 or TRP2 of the PCell occurs;

in a fourth case: TRP1 and TRP2 of the PCell are failed in wave beams;

in a fifth case: a beam failure occurs for TRP1 and TRP2 on different CCs of a PCell or SCell (may be referred to as PUCCH-SCell) capable of configuring Physical Uplink Control Channel (PUCCH) resources.

In the related art, a beam recovery procedure is proposed for a first case and a third case, that is, a case where only one TRP has a beam failure, but how to achieve beam failure recovery when multiple TRPs fail to transmit beams simultaneously (for example, a second case and a fourth case) (that is, all TRPs on a Pcell or one CC fail to transmit beams simultaneously) is a problem to be solved urgently at present.

An embodiment of the present application provides an information reporting method, which is applied to a terminal, and as shown in fig. 2, the method includes:

step 201: detecting that the link quality corresponding to the N first reference signal sets is lower than a first threshold value; n is an integer greater than 1;

step 202: reporting the first information to a network side; the first information comprises M reference signal identifications 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 are from M second reference signal sets.

The information reporting method provided in the embodiment of the present application may be understood as a method for reporting a beam failure request.

In step 201, N first reference signal sets correspond to N TRPs, that is, one first reference signal corresponds to one TRP, and when the link quality corresponding to the N first reference signal sets is lower than a first threshold, it indicates that a beam failure occurs in the N TRPs.

In practical application, the terminal may be referred to as a UE or a user.

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

The link quality corresponding to the N first reference signal sets is lower than a first threshold, which means that: the link corresponding to each of the N first reference signal sets is lower than a first threshold.

Here, all the reference signal qualities in each first reference signal set are lower than the first threshold, and when the number of times that all the reference signal qualities are lower than the first threshold within a certain time (which may be set as required) exceeds a preset number of times, it may be considered that the link corresponding to each first reference signal set is lower than the first threshold.

In practical application, a network side configures N first reference signal sets for the terminal, and simultaneously configures P second reference signal sets, wherein P is an integer less than or equal to N, and M is less than or equal to P; the N first reference signal sets and the P second reference signal sets have corresponding relations.

In step 202, the second set of reference signals may also be referred to as an alternative set of reference signals.

The M reference signal identifiers included in the first information refer to: the first information includes an identification of each of the M reference signals.

In an embodiment, the quality of each of the M reference signals is greater than or equal to the second threshold, which ensures the validity of the alternative beam.

Here, in practical applications, the quality of the reference signal may be layer 1-reference signal received power (L1-RSRP). The value of the second threshold can be set according to needs.

For P second reference signal sets configured on the network side, the terminal may determine the reported reference signal according to whether the terminal can simultaneously receive the reference signal in each second reference signal set, which may specifically include the following cases:

in the first case, for P second reference signal sets, if the terminal measures (may also be referred to as detects) reference signals whose L1-RSRP is greater than or equal to the second threshold from each second reference signal set, and the terminal can receive the reference signals simultaneously, the terminal reports the identities of the P second reference signals that can be received simultaneously, where M is equal to P.

Exemplarily, taking two TRPs as an example, if the terminal detects that both TRPs fail in a CC, the terminal measures reference signals with L1-RSRP greater than or equal to the second threshold from each of the second reference signal sets associated with the two TRPs with beam failure configured on the network side, and when the terminal can receive the 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.

In the second case, for P second reference signal sets, if the terminal measures reference signals with L1-RSRP greater than or equal to the second threshold from each second reference signal set and the terminal cannot receive the reference signals at the same time, the terminal reports the identities of the P second reference signals, where M is equal to P.

Illustratively, taking two TRPs as an example, if the terminal detects that both TRPs fail in a CC, and if the terminal detects that both TRPs fail in a CC, the terminal measures a reference signal whose L1-RSRP is greater than or equal to the second threshold from each of the second reference signal sets associated with the two TRPs in which the beam failure occurs, which are configured on the network side, but the terminal cannot receive the two reference signals at the same time, the terminal reports the identifier of the two reference signals whose L1-RSRP is greater than or equal to the second threshold.

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

In a 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 the reference signals at the same time, the terminal reports the identities of the M second reference signals.

In a fifth case, for P second reference signal sets, if the terminal only measures a reference signal with L1-RSRP greater than or equal to the second threshold from 1 second reference signal set, the terminal reports the identifier of the reference signal.

Illustratively, taking two TRPs as an example, if the terminal detects that both TRPs fail in a CC, and if the terminal detects that both TRPs fail in a CC, the terminal measures a reference signal with L1-RSRP greater than or equal to a second threshold from one of second reference signal sets associated with the two TRPs with beam failure configured on the network side, and at this time, the terminal reports an identifier of a reference signal with L1-RSRP greater than or equal to the second threshold.

In a sixth scenario, for the P second reference signal sets, the terminal does not measure the reference signals with L1-RSRP greater than or equal to the second threshold from none of the P second reference signal sets, and at this time, the terminal does not report the candidate beam reference signal, that is, does not send the first information.

In practical application, when at least two reference signals with L1-RSRP greater than or equal to the second threshold are measured in one second reference signal set, the terminal may select one reference signal as an alternative reference signal as needed for reporting to the network side, for example, select a reference signal with the largest L1-RSRP from the at least two reference signals as the alternative reference signal.

In practical applications, 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 comprises M reference signal identifications and second information.

In an embodiment, the terminal may report the first information to a network side through a MAC CE, so that the terminal is compatible with a related technology and is convenient to implement.

The resource for transmitting 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 carried by a PRACH.

Based on this, in an embodiment, the MAC CE is carried over a PUSCH or a PRACH.

Wherein, when the MAC CE is carried by the PRACH, the first information may be reported by Msg3 (applicable to a four-step random access procedure) or Msg a (applicable to a two-step random access procedure).

In practical application, when the terminal reports the first information through the Msg3 and receives the message 4 (Msg 4), the network side is considered to successfully receive the first information reported by the terminal, namely the alternative beam information.

And when the terminal reports the first information through the Msg A and receives the message B (Msg B), the network side is considered to successfully receive the first information reported by the terminal.

After the network side successfully receives the first information reported by the terminal, the terminal may transmit information in the same spatial direction as at least one of the M reference signals (which may be reference signals that can be received simultaneously in the M reference signals), and may also receive information using a DMRS that is spatially quasi-co-located with the at least one of the M reference signals.

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

When the terminal reports the identifiers of the two reference signals, where L1-RSRP is greater than or equal to the second threshold, corresponding to the two TRPs, and the two reference signals cannot be received by the terminal at the same time, the terminal may use one of the two reference signals (which reference signal may be adopted may be determined by the network side, the network side transmits information in the same direction as the one of the two reference signals, and the terminal receives information in a DMRS spatially co-located with the reference signal, that is, may know which reference signal to use) in the same spatial direction, and may also use the received information spatially co-located with the one of the two reference signals, that is, recover to single TRP (single-TRP) transmission.

The spatial direction may also be referred to as a beam direction.

Correspondingly, an embodiment of the present application further provides an information reporting method, which is applied to a network device (specifically, a base station), and as shown in fig. 3, the method includes:

step 301: receiving first information reported by a terminal after detecting that the link quality corresponding to N first reference signal sets is lower than a first threshold; n is an integer greater than 1; the first information comprises M reference signal identifications 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 are from M second reference signal sets.

In an embodiment, the network device receives, through an MAC CE, first information reported by the terminal.

Here, in an embodiment, the MAC CE is carried over a PUSCH or a PRACH.

In an embodiment, the first message is received through Msg3 or Msg a in a case where the MAC CE is carried through PRACH.

As shown in fig. 3, the method may further include:

step 302: with the first information, transmission is reverted to multi-TRP transmission or single-TRP transmission.

Specifically, the network device transmits information using the same spatial direction as at least one of the M reference signals;

and/or the presence of a gas in the atmosphere,

the network device receives information using a DMRS that is spatially quasi-co-located with at least one of the M reference signals.

More specifically, when M is equal to 1, the network device transmits information according to the spatial direction corresponding to the reference signal identifier, and receives information by using a DMRS spatially quasi-co-located with the reference signal port, that is, recovers to single-TRP transmission. Exemplarily, taking two TRPs as an example, if the terminal detects that both TRPs fail in a CC, the terminal only reports an identifier of a reference signal whose L1-RSRP is greater than or equal to the second threshold, and at this time, the network device sends information in a spatial direction corresponding to the identifier of the reference signal and receives information using a DMRS spatially quasi co-located with the reference signal port.

And when M is larger than 1, and the M reference signals can not be simultaneously received by the terminal, the network equipment selects one reference signal from the M reference signals, transmits information in the spatial direction corresponding to the selected reference signal identifier, and receives the information by using the DMRS which is spatially quasi-co-located with the selected reference signal port, namely recovers single-TRP transmission. Exemplarily, taking two TRPs as an example, if the terminal detects that both TRPs fail in a CC, the terminal reports 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 a spatial direction corresponding to the selected reference signal identifier, and receives information using a DMRS quasi-co-located with the selected reference signal port space.

Here, the network device may randomly select one reference signal from M reference signals, and the embodiment of the present application does not limit a specific processing procedure for selecting one reference signal from M reference signals.

When M is greater than 1, and at least two reference signals in the M reference signals can be received by the terminal at the same time, the network device may transmit information in the spatial direction corresponding to the at least two reference signal identifiers, and receive information using a DMRS spatially quasi-co-located with the at least two reference signal ports, that is, recover to multi-TRP transmission.

An embodiment of the present application further provides an information reporting method, as shown in fig. 4, where the method includes:

step 401: the terminal detects that the link quality corresponding to the N first reference signal sets is lower than a first threshold value; n is an integer greater than 1;

step 402: the terminal reports first information to the network equipment; the first information comprises M reference signal identifications 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 are from M second reference signal sets;

step 403: the network device receives the first information.

Here, it should be noted that: the specific processing procedures of the terminal and the network device have been described in detail above, and are not described in detail here.
