Technical Field

Background

Currently, in the process of reporting beam measurement, a base station sends a Channel State Information Reference Signal or a Synchronization Signal to a terminal, the terminal measures the Channel State Information Reference Signal or the Synchronization Signal, and selects a beam according to a L1-RSRP (Layer 1Reference Signal received power) or a L1-SINR (Layer 1Signal to Interference plus Noise Ratio) measurement result to report to a network device, the network device determines a better beam direction based on the report result of the terminal, and configures CRI (Channel State Information Reference Signal ) resource indicator, CSI-RS resource indicator, i.e. CSI-RS Identifier/SSBID (SSB (Synchronization Signal and PBCH block, Synchronization Signal) Identifier) into a spatial Information relationship for indicating a beam direction of a spatial relationship (spatial Information) uplink, namely, the terminal performs uplink transmission according to the uplink beam direction indicated by the CRI/SSBID sent by the network device, namely, the terminal device performs transmission through the uplink sending beam corresponding to the downlink receiving beam. Thus, when the terminal device uses the uplink transmission beam to transmit uplink data, the direction of the uplink transmission beam just faces the human body, which causes the terminal device to exceed MPE (Maximum Permissible radiation) when using the beam to transmit uplink data, and further requires power backoff, resulting in poor uplink transmission performance.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The embodiment of the invention provides an information reporting method, a repeated transmission control method and related equipment, which are used for solving the problems that in the existing repeated transmission scheme, a sending end cannot distinguish the times of correctly demodulating a physical channel by a target receiving end, so that the repeated transmission times of subsequent physical channels are difficult to reasonably adjust, and further the waste of physical resources is easily caused.

Referring to fig. 1, fig. 1 is a flowchart of an information reporting method provided in an embodiment of the present invention, where the method is used for a terminal device, and as shown in fig. 1, the method includes the following steps:

step 101: reporting the first information to the network equipment;

the first information includes a first channel state information reference Signal CSI-RS flag or a first synchronization Signal SSB flag, and a first Layer first reference Signal received power L1-RSRP (Layer 1reference Signal received power) or a first Layer first Signal to Interference plus Noise Ratio L1-SINR (Layer 1Signal to Interference plus Noise Ratio), or,

the first information comprises a first channel state information reference signal (CSI-RS) identifier or a first Synchronization Signal (SSB) identifier, and a first layer first reference signal received power (L1-RSRP) or a first layer first signal to interference plus noise ratio (L1-SINR), and a first parameter.

It is to be understood that, in one example, the first information includes a first channel state information reference signal CSI-RS identifier or a first synchronization signal SSB identifier, and a first layer first reference signal received power L1-RSRP or a first layer first signal to interference plus noise ratio L1-SINR, the first L1-RSRP is L1-RSRP corresponding to the first CSI-RS identifier or the first SSB identifier, and the first L1-SINR is L1-SINR corresponding to the first CSI-RS identifier or the first SSB identifier.

In this example, the first information may include the first CSI-RS identity and the first L1-RSRP, or may include the first SSB identity and the first L1-RSRP, or may include the first CSI-RS identity and the first L1-SINR, or may include the first SSB identity and the first L1-SINR.

Alternatively, in another example, the first information may include a first channel state information reference signal, CSI-RS, identity or a first synchronization signal, SSB, identity, and a first layer first reference signal received power, L1-RSRP, or a first layer first signal to interference plus noise ratio, L1-SINR, and the first parameter.

In this example, the first reported information is added with a first parameter, and the first information may include a first CSI-RS identifier, a first L1-RSRP, and the first parameter, or may include a first SSB identifier, a first L1-RSRP, and the first parameter, or may include the first CSI-RS identifier, the first L1-SINR, and the first parameter, or may include the first SSB identifier, the first L1-SINR, and the first parameter.

In the information reporting method of this embodiment, in the process of reporting information to the network device by the terminal device, the reported first information may include a first CSI-RS identifier or a first SSB identifier, and a first layer first reference signal received power L1-RSRP or a first layer first signal to interference plus noise ratio L1-SINR, or may include the first CSI-RS identifier or the first SSB identifier, and the first layer first reference signal received power L1-RSRP or the first layer first signal to interference plus noise ratio L1-SINR, and a first parameter. The terminal equipment can transmit the uplink data by using the spatial relationship for uplink transmission corresponding to the first CSI-RS identifier or the first SSB identifier, so that the situation that power backoff is easily caused in the process of transmitting the uplink data by using the reported spatial relationship for uplink transmission corresponding to the spatial relationship for downlink transmission can be reduced, and the uplink transmission performance can be improved.

It should be noted that, as an example, the first CSI-RS identifier or the first SSB identifier may be used to determine a spatial relationship for uplink transmission. As an example, the spatial relationship for uplink transmission may include an uplink beam (i.e., an uplink transmission beam), and it is understood that the uplink beam is a beam corresponding to the first CSI-RS identifier or the first SSB identifier.

The terminal device reports the first CSI-RS identifier or the first SSB identifier for determining the spatial relationship for uplink transmission, which indicates that the terminal device can transmit uplink data using the spatial relationship for uplink transmission determined by the first CSI-RS identifier or the first SSB identifier, that is, the terminal device can transmit uplink data using the spatial relationship for uplink transmission corresponding to the first CSI-RS identifier or the first SSB identifier, which is determined by the first CSI-RS identifier or the first SSB identifier.

Optionally, the first parameter is used to indicate that the first CSI-RS identifier or the first SSB identifier represents a spatial relationship for uplink transmission.

In this embodiment, in the first information, on the basis of the first CSI-RS flag or the first synchronization signal SSB flag, and the first layer first reference signal received power L1-RSRP or the first layer first signal to interference plus noise ratio L1-SINR, a first parameter is added to indicate that the first CSI-RS flag or the first SSB flag represents a spatial relationship for uplink transmission. That is, the first CSI-RS identifier or the first SSB identifier is indicated by the first parameter to represent a spatial relationship for uplink transmission, it can be understood that the spatial relationship for uplink transmission is a spatial relationship corresponding to the first CSI-RS identifier or the first SSB identifier, and the spatial relationship for uplink transmission can be determined by the first CSI-RS identifier or the first SSB identifier. As an example, the spatial relationship for uplink transmission may include an uplink beam, and the first CSI-RS identifier or the first SSB identifier is indicated by the first parameter to represent the uplink beam, that is, the beam corresponding to the first CSI-RS identifier or the first SSB identifier is an uplink beam.

Optionally, the first CSI-RS identifier or the first SSB identifier is a first CSI-RS identifier or a first SSB identifier determined from the multiple CSI-RSs or the multiple SSBs based on a power backoff condition caused when the multiple CSI-RSs or the multiple SSBs determine the spatial relationship for uplink transmission.

It can be understood that the first CSI-RS identifier or the first SSB identifier is a first CSI-RS identifier or a first SSB identifier determined from the multiple CSI-RSs or the multiple SSBs based on a power backoff condition of a spatial relationship corresponding to the multiple CSI-RSs or the multiple SSBs. The terminal device may receive multiple CSI-RSs or multiple SSBs sent by the network device for beam measurement before reporting the first information, and the terminal device may perform beam measurement based on the multiple CSI-RSs or multiple SSBs, and determine multiple L1-RSRPs or multiple L1-SINRs, for example, perform beam measurement based on the multiple CSI-RSs, determine multiple L1-RSRPs or multiple L1-SINRs, or determine multiple L1-RSRPs or multiple L1-SINRs based on the multiple SSBs. In the process of performing uplink data transmission (i.e., as an uplink beam) by using beams corresponding to multiple CSI-RSs or multiple SSBs, based on consideration of MPE (Maximum allowed radiation), power backoff may be required to reduce uplink performance, so in this embodiment, in the selection process of a spatial relationship for performing uplink transmission, in consideration of a power backoff condition, an identifier of a first CSI-RS or an identifier of a first SSB determined from the multiple CSI-RSs or the multiple SSBs is reported to a network device, and thus, when performing uplink data transmission by using the spatial relationship for uplink transmission corresponding to the identifier of the first CSI-RS or the identifier of the first SSB, the uplink transmission performance may be improved. As an example, the plurality of L1-RSRPs or the plurality of L1-SINRs are a plurality of L1-RSRPs or a plurality of L1-SINRs determined under the condition of considering the power back-off of the spatial relationship corresponding to the plurality of CSI-RSs or the plurality of SSBs, and the first CSI-RS identifier or the first SSB identifier may be a CSI-RS identifier or an SSB identifier with the largest L1-RSRP or L1-SINR among the plurality of CSI-RS identifiers or the plurality of SSB identifiers.

As an example, optionally, reporting the first information to the network device includes:

and reporting the first information to the network equipment under the condition of meeting a first preset condition.

In view of the power backoff caused by the MPE problem occurring in some specific cases, in this embodiment, the trigger condition for increasing information reporting is to report the first information to the network device when the first preset condition is met.

Optionally, the first preset condition includes any one of:

the maximum L1-RSRP in the plurality of L1-RSRPs is smaller than a first preset threshold;

the maximum L1-SINR in the plurality of L1-SINRs is smaller than a second preset threshold;

the difference between the uplink resource allocated by the terminal equipment and the maximum uplink duty ratio MaxUplinkDutyCycle is smaller than a first preset value;

the first CSI-RS identification or the first SSB identification used for determining the spatial relationship of the uplink transmission is inconsistent with the second CSI-RS identification or the second SSB identification used for determining the spatial relationship of the downlink transmission.

The first preset threshold and the second preset threshold may be indicated by the network device, for example, the network device indicates an RSRP/SINR measurement threshold of the SSB/CSI-RS in broadcast information or through RRC signaling, that is, the first preset threshold/the second preset threshold, and a threshold lower than the first preset threshold/the second preset threshold means that the threshold is at a cell edge and can be used as one of triggering conditions for information reporting. Or the difference between the uplink resource scheduled by the terminal device in the first time window and the maximum uplink duty ratio maxuplinkdtycycle is smaller than a first preset value, which indicates that the uplink resource scheduled by the terminal device in the first time window approaches or reaches the maxuplinkdtycycle, and in this case, power backoff is easily generated, so that the difference between the uplink resource allocated by the terminal device and the maximum uplink duty ratio maxuplinkdtycycle can also be smaller than the first preset value as one of the triggering conditions for information reporting.

Or considering that if no power backoff occurs, the uplink optimal beam (beam for uplink transmission) and the downlink optimal beam (beam for downlink transmission) should be consistent, and in the case of power backoff, the uplink optimal beam and the downlink optimal beam are inconsistent, so that the inconsistency between the uplink optimal beam and the downlink optimal beam can be used as one of the trigger conditions for information reporting, that is, the first CSI-RS identifier or the first SSB identifier corresponding to the spatial relationship for determining uplink transmission is inconsistent with the second CSI-RS identifier or the second SSB identifier for determining the spatial relationship for downlink transmission, the beam corresponding to the second CSI-RS identifier or the second SSB identifier is a downlink beam for downlink transmission, and the first CSI-RS identifier or the first SSB identifier for determining the spatial relationship for uplink transmission is inconsistent with the second CSI-RS identifier or the second SSB identifier for determining the spatial relationship for downlink transmission, i.e., indicating that the spatial relationship for uplink transmissions is not consistent with the spatial relationship for downlink transmissions.

Optionally, before reporting the first information to the network device, the method further includes:

and sending the triggering signaling to the network equipment.

Before reporting the first information to the network device, the terminal device may send a trigger signaling to the network device to trigger the network device to send multiple CSI-RSs or multiple SSBs for beam measurement, and after receiving the multiple CSI-RSs or the multiple SSBs, the terminal performs beam measurement and reports the first information to the network device.

Optionally, sending the trigger signaling to the network device includes:

and reporting the triggering signaling in a media access control layer control unit (MAC CE) or a Physical Uplink Control Channel (PUCCH).

Media Access Control Element (MAC), the name of which is Media Access Control Element (MAC), and Control Element (CE), the name of which is Control Element (CE). The PUCCH is Physical Uplink Control Channel, which is referred to as Physical Uplink Control Channel in chinese. That is, in this embodiment, the trigger signaling may be carried in the MAC CE or PUCCH and reported to the network device, and the network device receives the MAC CE or PUCCH, and may obtain the trigger signaling based on the MAC CE or PUCCH.

Optionally, sending the trigger signaling to the network device includes:

and sending a trigger signaling to the network equipment under the condition of meeting a second preset condition.

Optionally, the second preset condition includes any one of:

the maximum L1-RSRP in the plurality of second L1-RSRPs is smaller than a third preset threshold;

the maximum L1-SINR in the plurality of second L1-SINRs is smaller than a fourth preset threshold;

the difference between the uplink resource allocated by the terminal equipment and the maximum uplink duty ratio MaxUplinkDutyCycle is smaller than a second preset value;

and the third CSI-RS identifier or the third SSB identifier used for determining the spatial relationship of the uplink transmission is inconsistent with the fourth CSI-RS identifier or the fourth SSB identifier used for determining the spatial relationship of the downlink transmission.

The third CSI-RS identifier or the third SSB identifier is determined from the plurality of second CSI-RSs or the plurality of second SSBs based on the power back-off condition of the spatial relationship corresponding to the plurality of second CSI-RSs or the plurality of second SSBs. The terminal device may receive a plurality of second CSI-RSs or a plurality of second SSBs for beam measurement sent by the network device before reporting the trigger signaling, and determine a plurality of second L1-RSRPs or a plurality of second L1-SINRs based on the plurality of second CSI-RSs or the plurality of second SSBs being capable of beam measurement, for example, determine a plurality of second L1-RSRPs or a plurality of second L1-SINRs based on the plurality of second CSI-RSs being capable of beam measurement, or determine a plurality of second L1-RSRP or a plurality of second L1-SINRs based on the plurality of second SSBs being capable of beam measurement. As an example, the second plurality of L1-RSRP or the second plurality of L1-SINR are a plurality of L1-RSRP or a plurality of L1-SINR determined considering power backoff of spatial relationship corresponding to the CSI-RS or the SSB, and the third CSI-RS identifier or the third SSB identifier may be a CSI-RS identifier or an SSB identifier with the largest L1-RSRP or L1-SINR among the second CSI-RS identifiers or the second SSB identifiers. As an example, the third CSI-RS identifier or the third SSB identifier is an identifier of a third CSI-RS or an identifier of a third SSB determined from the plurality of second CSI-RS or the plurality of second SSB based on a power backoff condition when a spatial relationship (beam) corresponding to the plurality of second CSI-RS or the plurality of second SSB is used as a spatial relationship for uplink transmission (when the spatial relationship for uplink transmission is determined based on the plurality of second CSI-RS or the plurality of second SSB).

The third preset threshold and the fourth preset threshold may be indicated by the network device, for example, the network device indicates the third preset threshold/the fourth preset threshold in broadcast information or through RRC signaling, and a value lower than the third preset threshold/the fourth preset threshold means that the threshold may be one of trigger conditions for sending trigger signaling at a cell edge. Or the difference between the uplink resource scheduled by the terminal device in the second time window and the maximum uplink duty ratio maxuplinkdtycycle is smaller than the first preset value, which indicates that the uplink resource scheduled by the terminal device in the second time window approaches or reaches the maxuplinkdtycycle, in this case, power backoff is easily generated, and thus, the difference between the uplink resource allocated by the terminal device and the maximum uplink duty ratio maxuplinkdtycycle may also be smaller than the first preset value as one of the trigger conditions for sending the trigger signaling.

Or considering that if no power backoff occurs, the uplink optimal beam (beam for uplink transmission) and the downlink optimal beam (beam for downlink transmission) should be consistent, and in the case of power backoff, the uplink optimal beam and the downlink optimal beam are inconsistent, so that inconsistency between the uplink optimal beam and the downlink optimal beam can be used as one of the trigger conditions for sending the trigger signaling, that is, inconsistency between the third CSI-RS identifier or the third SSB identifier corresponding to the above spatial relationship for determining uplink transmission and the fourth CSI-RS identifier or the fourth SSB identifier for determining spatial relationship for downlink transmission, inconsistency between the beam corresponding to the fourth CSI-RS identifier or the fourth SSB identifier and the downlink beam for determining downlink transmission, inconsistency between the third CSI-RS identifier or the third SSB identifier for determining spatial relationship for uplink transmission and the fourth CSI-RS identifier or the fourth SSB identifier for determining spatial relationship for downlink transmission, i.e., indicating that the spatial relationship for uplink transmissions is not consistent with the spatial relationship for downlink transmissions. In addition, the third CSI-RS identifier or the third SSB identifier used for determining the spatial relationship of the uplink transmission is inconsistent with the fourth CSI-RS identifier or the fourth SSB identifier used for determining the spatial relationship of the downlink transmission, which also means that the spatial relationship used for the uplink transmission is inconsistent with the spatial relationship used for the downlink transmission.

Referring to fig. 2, fig. 2 is a flowchart of an information receiving method according to an embodiment of the present invention, for a network device, as shown in fig. 2, the method includes the following steps:

step 201: receiving first information reported by terminal equipment;

The network device can receive the spatial relationship for uplink transmission corresponding to the first CSI-RS identifier or the first SSB identifier used by the terminal device to transmit the uplink data, and can reduce the situation that power backoff is easily caused in the process of transmitting the uplink data by using the reported spatial relationship for uplink transmission corresponding to the spatial relationship for downlink transmission, thereby improving the uplink transmission performance.

As one example, a first CSI-RS identity or a first SSB identity is used to determine a spatial relationship for uplink transmission.

Optionally, the receiving the first information reported by the terminal device includes:

and receiving first information reported by the terminal equipment under the condition of meeting a first preset condition.

Optionally, the first preset condition includes any one of:

Optionally, before receiving the first information reported by the terminal device, the method further includes:

and receiving a trigger signaling sent by the terminal equipment.

Optionally, the receiving of the trigger signaling sent by the terminal device includes:

and receiving a trigger signaling reported by the terminal equipment in a Media Access Control (MAC) control unit (CE) or a Physical Uplink Control Channel (PUCCH).

and receiving a trigger signaling sent by the terminal equipment under the condition of meeting a second preset condition.

Optionally, the second preset condition includes any one of:

the maximum L1-RSRP in the plurality of second L1-RSRP is smaller than a third preset threshold;

The following describes the procedures of the above-mentioned information reporting method and information receiving method in a specific embodiment.

MPE is used for the FR2 frequency range, which characterizes the maximum allowable radiation power in a certain area against the human body, and FR1 (a frequency range) is expressed as SAR (specific absorption rate).

A terminal device (e.g., ue (user equipment), that is, user equipment) reports the capability, and when the number of uplink symbols (i.e., uplink resources scheduled by the terminal device) in a time window (e.g., 1s) exceeds the value, the terminal device needs to perform power backoff to reduce the damage to a human body.

MPE detection can be carried out when the terminal equipment leaves a factory, and the detection standard is that the MPE requirement can be met when the terminal equipment sends full power when the MaxUpLinkDutyCycle is met, so that the MPE detection method is less or harmless to human bodies.

In the network, when the terminal equipment is located at the edge of a cell and exceeds a MaxUplinkDutyCycle, the terminal equipment needs to perform power backoff, the uplink performance of a cell edge user is not good, and the uplink performance is seriously influenced by performing power backoff. Currently, downlink beam measurement only measures a beam received by a terminal device in a downlink manner, and selects a better receiving beam to report to a network device (e.g., a base station), but it is possible that an uplink transmission beam direction corresponding to the downlink receiving beam just faces a human body, which causes the terminal to exceed an MPE index when transmitting uplink data using the beam, and further requires power backoff to affect uplink performance.

Based on the consideration that MPE and MPE cause power back-off to occur in specific situations, a 'decision mechanism', namely a trigger condition, is added in the embodiment of the application.

For example, the network device indicates an RSRP or SINR measurement threshold of the SSB/CSI-RS in broadcast information or RRC signaling, and a threshold below this threshold means at the cell edge may be one of the trigger conditions. Or the uplink resource scheduled by the terminal device in the first time window reaches or approaches the MaxUplinkDutyCycle condition, and the condition is taken as one of the trigger conditions. Or the inconsistency of the uplink and downlink optimal beams is taken as one of the trigger conditions.

When the trigger condition is valid, the terminal device needs to additionally report a first CRI (first CSI-RS id)/a first SSBID (first SSB id), a first L1-RSRP or a first L1-SINR, and a parameter a (first parameter) when performing downlink beam reporting, where the parameter a is used to indicate an uplink transmission beam selected by the CRI/SSBID. When the trigger condition is not in effect, the current beam reporting mechanism is still adopted.

In another example, considering that MPE causes power back-off to occur in a specific situation, terminal device triggered UL (uplink) beam reporting, i.e. triggered uplink beam reporting, is increased.

As shown in fig. 3, taking reporting CRI/SSBID and L1-RSRP as an example for explanation, first, when the "decision mechanism" is in effect, the terminal device reports a trigger signaling to the base station in the MAC CE or in the PUCCH.

Then, the base station configures SSB/CSI-RS for UL beam measurement and sends the SSB/CSI-RS to the terminal equipment.

Secondly, the terminal equipment carries out beam measurement based on SSB/CSI-RS, considers the power back-off condition brought by MPE and comprehensively reports 1 or N (integer larger than 1) CRI/SSBID + L1-RSRP suitable for UL transmission.

Furthermore, the base station arranges SSBID/CRI (corresponding to SSB-Index/CSI-RS-Index in fig. 3) in spatial relationship information (spatial relationship information) for indicating a beam direction of an uplink PUCCH/SRS (Sounding Reference Signal).

By the information reporting method, the problem of uplink beam selection under the condition of power back-off brought by MPE is solved, and uplink transmission performance is improved.
