Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, and in particular to an information reporting method, an information receiving method, a terminal device and a network device. BACKGROUND

[0002] Currently, in the process of beam measurement reporting, the base station sends a channel state information reference signal or a synchronization signal to the terminal, the terminal measures the channel state information reference signal or the synchronization signal, and selects a beam to report to the network device according to the L1-RSRP (Layer 1 reference signal received power) or L1-SINR (Layer 1 Signal to Interference plus Noise Ratio) measurement result, the network device determines a better beam direction based on the reporting result of the terminal, and configures CRI (CSI-RS (Channel State Information Reference Signal) resource indicator, CSI-RS resource indicator) / SSBID (SSB (Synchronization Signal and PBCH block) Identifier, SSB identifier) into spatialrelationinfo (spatial relation information) for indicating the uplink beam direction, that is, the terminal performs uplink transmission according to the uplink beam direction indicated by the CRI / SSBID sent by the network device, that is, the terminal device performs transmission through the uplink transmission beam corresponding to the downlink reception beam. In this way, when the terminal device uses the uplink transmission beam to perform uplink data transmission, the uplink transmission beam direction is directly opposite to the human body, which causes the terminal device to exceed the MPE (Maximum Permissible Exposure) when using the beam to send uplink data, and thus power backoff is required, resulting in poor uplink transmission performance.

[0041] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0042] In the embodiments of the present application, a method for reporting information, a method for controlling repeated transmission and related devices are provided to solve the problem that in the existing repeated transmission scheme, the sending end cannot distinguish the number of times of correctly demodulating a physical channel by a target receiving end, so it is difficult to reasonably adjust the number of repeated transmissions of subsequent physical channels, and thus physical resources are easily wasted.

[0043] Referring to Figure 1 , Figure 1 is a flowchart of a method for reporting information provided by an embodiment of the present application, which is used for a terminal device, such as Figure 1 As shown in the figure, the method comprises the following steps:

[0044] Step 101: reporting first information to a network device;

[0045] 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 one reference signal received power L1-RSRP (Layer 1 reference signal received power) or a first layer one signal to interference plus noise ratio L1-SINR (Layer 1 Signal to Interference plus Noise Ratio), or

[0046] The first information includes a first channel state information reference signal (CSI-RS) identifier or a first synchronization signal (SSB) identifier, a first layer one reference signal received power (L1-RSRP) or a first layer one signal to interference plus noise ratio (L1-SINR), and a first parameter.

[0047] It can 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, a first layer one reference signal received power (L1-RSRP) or a first layer one signal to interference plus noise ratio (L1-SINR), the first L1-RSRP is the L1-RSRP corresponding to the first CSI-RS identifier or the first SSB identifier, and the first L1-SINR is the L1-SINR corresponding to the first CSI-RS identifier or the first SSB identifier.

[0048] In this example, the first information can include the first CSI-RS identifier and the first L1-RSRP, or can include the first SSB identifier and the first L1-RSRP, or can include the first CSI-RS identifier and the first L1-SINR, or can include the first SSB identifier and the first L1-SINR.

[0049] Alternatively, in another example, the first information includes a first channel state information reference signal (CSI-RS) identifier or a first synchronization signal (SSB) identifier, a first layer one reference signal received power (L1-RSRP) or a first layer one signal to interference plus noise ratio (L1-SINR), and a first parameter.

[0050] In this example, the first parameter is added to the reported first information, and the first information can include the first CSI-RS identifier, the first L1-RSRP, and the first parameter, or can include the first SSB identifier, the first L1-RSRP, and the first parameter, or can include the first CSI-RS identifier, the first L1-SINR, and the first parameter, or can include the first SSB identifier, the first L1-SINR, and the first parameter.

[0051] In the information reporting method of the embodiment, in the process of reporting information to the network device by the terminal device, the first information reported can include a first channel state information reference signal (CSI-RS) identifier or a first synchronization signal (SSB) identifier, and a first layer one reference signal received power (L1-RSRP) or a first layer one signal to interference plus noise ratio (L1-SINR), or can include a first channel state information reference signal (CSI-RS) identifier or a first synchronization signal (SSB) identifier, a first layer one reference signal received power (L1-RSRP) or a first layer one signal to interference plus noise ratio (L1-SINR), and a first parameter. The terminal device can use the spatial relationship for uplink transmission corresponding to the first CSI-RS identifier or the first SSB identifier to transmit uplink data, which can reduce the situation that power backoff is easily caused in the process of transmitting uplink data using the uplink transmission spatial relationship corresponding to the reported spatial relationship for downlink transmission, thereby improving the uplink transmission performance.

[0052] It should be noted that, as an example, the first CSI-RS identifier or the first SSB identifier can be used to determine the spatial relationship for uplink transmission. As an example, the spatial relationship for uplink transmission can include an uplink beam (i.e., an uplink transmission beam), and it can be understood that the uplink beam is a beam corresponding to the first CSI-RS identifier or the first SSB identifier.

[0053] The first CSI-RS identifier or the first SSB identifier is used to determine the spatial relationship for uplink transmission, and the terminal device itself reports the first CSI-RS identifier or the first SSB identifier used to determine the spatial relationship for uplink transmission, which indicates that the terminal device can use the spatial relationship for uplink transmission determined by the first CSI-RS identifier or the first SSB identifier to transmit uplink data, i.e., the terminal device can use the spatial relationship for uplink transmission corresponding to the first CSI-RS identifier or the first SSB identifier to transmit uplink data, which can reduce the situation that power backoff is easily caused in the process of transmitting uplink data using the uplink transmission spatial relationship corresponding to the reported spatial relationship for downlink transmission, thereby improving the uplink transmission performance.

[0054] Optionally, the first parameter is used to indicate that the first CSI-RS identifier or the first SSB identifier represents the spatial relationship for uplink transmission.

[0055] In the embodiment, in the first information, on the basis of the first channel state information reference signal (CSI-RS) identifier or the first synchronization signal (SSB) identifier and the first layer one reference signal received power (L1-RSRP) or the first layer one signal to interference plus noise ratio (L1-SINR), a first parameter is added to indicate that the first CSI-RS identifier or the first SSB identifier represents a spatial relation for uplink transmission. That is, the first parameter is used to indicate that the first CSI-RS identifier or the first SSB identifier represents a spatial relation for uplink transmission. It can be understood that the spatial relation for uplink transmission is the spatial relation corresponding to the first CSI-RS identifier or the first SSB identifier, and the spatial relation for uplink transmission can be determined through the first CSI-RS identifier or the first SSB identifier. As an example, the spatial relation for uplink transmission can include an uplink beam, and the first parameter is used to indicate that the first CSI-RS identifier or the first SSB identifier represents an uplink beam, that is, the beam corresponding to the first CSI-RS identifier or the first SSB identifier is an uplink beam.

[0056] Optionally, when the first CSI-RS identifier or the first SSB identifier is used to determine the spatial relation for uplink transmission based on multiple CSI-RSs or multiple SSBs, the first CSI-RS identifier or the first SSB identifier is determined from the multiple CSI-RSs or the multiple SSBs in a power backoff condition caused by determining the spatial relation for uplink transmission based on the multiple CSI-RSs or the multiple SSBs.

[0057] It can be understood that the first CSI-RS identifier or the first SSB identifier is an identifier of a first CSI-RS or an identifier of a first SSB determined from the multiple CSI-RSs or the multiple SSBs in a case of power backoff based on spatial relations corresponding to the multiple CSI-RSs or the multiple SSBs. Before reporting the first information, the terminal device can receive multiple CSI-RSs or multiple SSBs sent by the network device for beam measurement, and the terminal device can perform beam measurement based on the multiple CSI-RSs or the multiple SSBs to determine multiple L1-RSRPs or multiple L1-SINRs, for example, perform beam measurement based on the multiple CSI-RSs to determine multiple L1-RSRPs or multiple L1-SINRs, or perform beam measurement based on the multiple SSBs to determine multiple L1-RSRPs or multiple L1-SINRs. In the process of using the beams corresponding to the multiple CSI-RSs or the multiple SSBs for uplink data transmission (i.e., as uplink beams), power backoff may be required based on MPE (Maximum Permissible Exposure) considerations, which reduces uplink performance. Therefore, in this embodiment, the selection process of the spatial relation for uplink transmission takes into account the case of power backoff, and the identifier of the first CSI-RS or the identifier of the first SSB is reported to the network device. In this way, when the spatial relation corresponding to the first CSI-RS identifier or the first SSB identifier is used for uplink data transmission, the uplink transmission performance can be improved. As an example, the multiple L1-RSRPs or the multiple L1-SINRs are determined in a case of power backoff based on spatial relations corresponding to the multiple CSI-RSs or the multiple SSBs, and the first CSI-RS identifier or the first SSB identifier can be a CSI-RS identifier or an SSB identifier with the largest L1-RSRP or L1-SINR among the multiple CSI-RS identifiers or the multiple SSB identifiers.

[0058] As an example, reporting the first information to the network device includes:

[0059] In a case of satisfying a first preset condition, reporting the first information to the network device.

[0060] In this embodiment, the trigger condition for increasing information reporting is that the first information is reported to the network device in a case of satisfying a first preset condition, considering that power backoff occurs in some specific cases due to MPE problems.

[0061] Optionally, the first preset condition includes any of the following:

[0062] The largest L1-RSRP in the multiple L1-RSRPs is less than a first preset threshold;

[0063] the maximum L1-SINR in the plurality of L1-SINRs is less than a second preset threshold;

[0064] a difference between the uplink resource allocated to the terminal device and the maximum uplink duty cycle MaxUplinkDutyCycle is less than a first preset value;

[0065] a first CSI-RS identifier or a first SSB identifier used for determining a spatial relation of uplink transmission is inconsistent with a second CSI-RS identifier or a second SSB identifier used for determining a spatial relation of downlink transmission.

[0066] The first preset threshold and the second preset threshold can be indicated by the network device, for example, the network device indicates the RSRP / SINR measurement threshold of SSB / CSI-RS, i.e., the first preset threshold / second preset threshold, in broadcast information or through RRC signaling, and below this threshold means at the cell edge, which can be one of the trigger conditions for information reporting. Alternatively, a difference between the uplink resource scheduled to the terminal device in the first time window and the maximum uplink duty cycle MaxUplinkDutyCycle is less than a first preset value, indicating that the uplink resource scheduled to the terminal device in the first time window approaches or reaches MaxUplinkDutyCycle, and in this case, power backoff is prone to occur, so the difference between the uplink resource allocated to the terminal device and the maximum uplink duty cycle MaxUplinkDutyCycle less than the first preset value can also be one of the trigger conditions for information reporting.

[0067] Alternatively, considering that if power backoff does not occur, the uplink optimal beam (beam used for uplink transmission) and the downlink optimal beam (beam used 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 the inconsistency between the uplink optimal beam and the downlink optimal beam can be one of the trigger conditions for information reporting, i.e., the first CSI-RS identifier or the first SSB identifier used for determining the spatial relation of uplink transmission is inconsistent with the second CSI-RS identifier or the second SSB identifier used for determining the spatial relation of downlink transmission, the beam corresponding to the second CSI-RS identifier or the second SSB identifier is the downlink beam used for downlink transmission, and the first CSI-RS identifier or the first SSB identifier used for determining the spatial relation of uplink transmission is inconsistent with the second CSI-RS identifier or the second SSB identifier used for determining the spatial relation of downlink transmission, i.e., the spatial relation used for uplink transmission is inconsistent with the spatial relation used for downlink transmission.

[0068] Optionally, before reporting the first information to the network device, the method further comprises:

[0069] sending trigger signaling to the network device.

[0070] Before reporting the first information to the network device, the terminal device can send trigger signaling to the network device to trigger the network device to send a plurality of CSI-RSs or a plurality of SSBs for beam measurement, and the terminal device performs beam measurement after receiving the plurality of CSI-RSs or the plurality of SSBs, and then reports the first information to the network device.

[0071] Optionally, the sending of the trigger signaling to the network device comprises:

[0072] The trigger signaling is reported in a medium access control layer control element (MAC CE) or a physical uplink control channel (PUCCH).

[0073] MAC is an abbreviation of Media Access Control, and CE is an abbreviation of Control Element. PUCCH is an abbreviation of Physical Uplink Control Channel. That is, in the embodiment, the trigger signaling can be carried in the MAC CE or the PUCCH and reported to the network device. The network device receives the MAC CE or the PUCCH, and can obtain the trigger signaling based on the MAC CE or the PUCCH.

[0074] Optionally, the sending of the trigger signaling to the network device comprises:

[0075] The trigger signaling is sent to the network device when a second preset condition is met.

[0076] Optionally, the second preset condition comprises any one of the following:

[0077] A maximum L1-RSRP in the plurality of second L1-RSRPs is less than a third preset threshold;

[0078] A maximum L1-SINR in the plurality of second L1-SINRs is less than a fourth preset threshold;

[0079] A difference between an uplink resource allocated to the terminal device and a maximum uplink duty cycle (MaxUplinkDutyCycle) is less than a second preset value;

[0080] A third CSI-RS identifier or a third SSB identifier used for determining a spatial relationship of uplink transmission is inconsistent with a fourth CSI-RS identifier or a fourth SSB identifier used for determining a spatial relationship of downlink transmission.

[0081] 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 multiple second CSI-RSs or the multiple second SSBs in a case of power backoff based on spatial relations corresponding to the multiple second CSI-RSs or the multiple second SSBs. Before reporting the triggering signaling, the terminal device can receive the multiple second CSI-RSs or the multiple second SSBs sent by the network device for beam measurement, and the terminal device can perform beam measurement based on the multiple second CSI-RSs or the multiple second SSBs to determine multiple second L1-RSRPs or multiple second L1-SINRs, for example, perform beam measurement based on the multiple second CSI-RSs to determine multiple second L1-RSRPs or multiple second L1-SINRs, or perform beam measurement based on the multiple second SSBs to determine multiple second L1-RSRPs or multiple second L1-SINRs. As an example, the multiple second L1-RSRPs or the multiple second L1-SINRs are multiple L1-RSRPs or multiple L1-SINRs determined in a case of power backoff based on spatial relations corresponding to the multiple CSI-RSs or the multiple SSBs, and the third CSI-RS identifier or the third SSB identifier can be an identifier of a CSI-RS or an identifier of an SSB with the largest L1-RSRP or L1-SINR among the multiple second CSI-RS identifiers or the multiple 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 multiple second CSI-RSs or the multiple second SSBs in a case of power backoff based on spatial relations (beams) used for uplink transmission when the spatial relations for uplink transmission are determined based on the multiple second CSI-RSs or the multiple second SSBs.

[0082] The third preset threshold and the fourth preset threshold can 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 difference between the third preset threshold / the fourth preset threshold and a maximum uplink duty cycle MaxUplinkDutyCycle indicates that the terminal device is at the cell edge, which can be used as one of the triggering conditions for sending the triggering signaling. Alternatively, a difference between the uplink resource scheduled for the terminal device in the second time window and the maximum uplink duty cycle MaxUplinkDutyCycle is less than a first preset value, which indicates that the uplink resource scheduled for the terminal device in the second time window approaches or reaches the maximum uplink duty cycle MaxUplinkDutyCycle, and in this case, power backoff is likely to occur. Therefore, the difference between the uplink resource allocated to the terminal device and the maximum uplink duty cycle MaxUplinkDutyCycle less than the first preset value can also be used as one of the triggering conditions for sending the triggering signaling.

[0083] Or consider that if the power backoff does not occur, the uplink optimal beam (the beam used for uplink transmission) and the downlink optimal beam (the beam used for downlink transmission) should be consistent, and in the case of power backoff, the inconsistency of the uplink optimal beam and the downlink optimal beam, so that the inconsistency of the uplink optimal beam and the downlink optimal beam can be used as one of the triggering conditions for sending triggering signaling, that is, the third CSI-RS identifier or the third SSB identifier corresponding to the determination of the spatial relationship of the uplink transmission and the fourth CSI-RS identifier or the fourth SSB identifier corresponding to the determination of the spatial relationship of the downlink transmission are inconsistent, and the beam corresponding to the fourth CSI-RS identifier or the fourth SSB identifier is the downlink beam used for downlink transmission, and the third CSI-RS identifier or the third SSB identifier corresponding to the determination of the spatial relationship of the uplink transmission and the fourth CSI-RS identifier or the fourth SSB identifier corresponding to the determination of the spatial relationship of the downlink transmission are inconsistent, that is, the spatial relationship for uplink transmission and the spatial relationship for downlink transmission are inconsistent. In addition, the third CSI-RS identifier or the third SSB identifier corresponding to the determination of the spatial relationship of the uplink transmission and the fourth CSI-RS identifier or the fourth SSB identifier corresponding to the determination of the spatial relationship of the downlink transmission are inconsistent, which also indicates that the spatial relationship for uplink transmission and the spatial relationship for downlink transmission are inconsistent.

[0084] Referring to Figure 2 , Figure 2 is a flowchart of an information receiving method provided by an embodiment of the present application, which is used for a network device, such as a base station. Figure 2 As shown in the figure, the method comprises the following steps:

[0085] Step 201: receiving first information reported by a terminal device;

[0086] 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 one reference signal receiving power (L1-RSRP) or a first layer one signal to interference plus noise ratio (L1-SINR), or

[0087] 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 one reference signal receiving power (L1-RSRP) or a first layer one signal to interference plus noise ratio (L1-SINR), and a first parameter.

[0088] The network device can receive the terminal device to transmit uplink data using the spatial relationship for uplink transmission corresponding to the first CSI-RS identifier or the first SSB identifier, which can reduce the situation that the process of transmitting uplink data using the spatial relationship for uplink transmission corresponding to the reported spatial relationship for downlink transmission is prone to cause power backoff, thereby improving the uplink transmission performance.

[0089] As an example, the first CSI-RS identity or the first SSB identity is used to determine the spatial relation for the uplink transmission.

[0090] Optionally, the first parameter is used to indicate that the first CSI-RS identity or the first SSB identity represents the spatial relation for the uplink transmission.

[0091] Optionally, the first CSI-RS identity or the first SSB identity is determined from the first CSI-RS identity or the first SSB identity based on a power backoff condition caused by determining the spatial relation for the uplink transmission based on multiple CSI-RSs or multiple SSBs.

[0092] Optionally, the first information reported by the terminal device is received, including:

[0093] The first information reported by the terminal device in a case where a first preset condition is met is received.

[0095] A maximum L1-RSRP in the multiple L1-RSRPs is less than a first preset threshold;

[0096] A maximum L1-SINR in the multiple L1-SINRs is less than a second preset threshold;

[0097] A difference between the uplink resource allocated to the terminal device and a maximum uplink duty cycle MaxUplinkDutyCycle is less than a first preset value;

[0098] The first CSI-RS identity or the first SSB identity used to determine the spatial relation for the uplink transmission is inconsistent with a second CSI-RS identity or a second SSB identity used to determine the spatial relation for the downlink transmission.

[0099] Optionally, before receiving the first information reported by the terminal device, the method further includes:

[0105] Optionally, the second preset condition includes any of the following:

[0106] The maximum L1-RSRP in the plurality of second L1-RSRPs is less than a third preset threshold;

[0107] The maximum L1-SINR in the plurality of second L1-SINRs is less than a fourth preset threshold;

[0108] The difference between the uplink resource allocated to the terminal device and the maximum uplink duty cycle MaxUplinkDutyCycle is less than a second preset value;

[0109] 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.

[0110] The following will specifically describe the process of the information reporting method and the information receiving method with one specific embodiment.

[0111] MPE is used for FR2 frequency range, which represents the maximum allowed radiation power in a certain area against the human body, and FR1 (a frequency range) uses SAR (specific absorption rate) to represent.

[0112] MaxUplinkDutyCycle (maximum uplink duty cycle): The terminal device (for example, UE (User Equipment), that is, user equipment) reports this capability. When the number of uplink symbols (that is, the uplink resource scheduled by the terminal device) in a time window (for example, 1s) exceeds this value, the terminal device needs to perform power backoff to reduce the harm to the human body.

[0113] The terminal device will perform MPE detection when it is out of the factory. The detection standard is that the terminal device can meet the MPE requirement when performing full-power transmission at MaxUplinkDutyCycle, which has little or no harm to the human body.

[0114] In the network, when the terminal device is located at the edge of the cell and exceeds MaxUplinkDutyCycle, the terminal device needs to perform power backoff. The uplink performance of the user at the edge of the cell is not good, and further power backoff will seriously affect the uplink performance. Currently, downlink beam measurement only measures the downlink receiving beam of the terminal device and selects a better receiving beam to report to the network device (for example, a base station), but the uplink transmission beam direction corresponding to the downlink receiving beam may be just against the human body, which leads to that the terminal device will exceed the MPE index when transmitting uplink data by using the beam, and then needs to perform power backoff to affect the uplink performance.

[0115] Based on the consideration of MPE and the occurrence of power back-off caused by MPE under specific circumstances, this application embodiment adds a "decision mechanism", namely the triggering condition.

[0116] For example, network devices may use broadcast messages or RRC signaling to indicate the RSRP or SINR measurement threshold of the SSB / CSI-RS. A measurement below this threshold, indicating a cell edge location, can serve as one of the triggering conditions. Alternatively, the uplink resources scheduled for the terminal device within the first time window may reach or approach the MaxUplinkDutyCycle, also serving as a triggering condition. Another triggering condition may be the inconsistency between the optimal uplink and downlink beams.

[0117] When the triggering condition is active, the terminal device needs to additionally report the first CRI (first CSI-RS identifier) / first SSBID (first SSB identifier), the first L1-RSRP or the first L1-SINR, and parameter A (first parameter) when reporting downlink beams. Parameter A is used to indicate the uplink transmission beam selected by the CRI / SSBID. When the triggering condition is not active, the current beam reporting mechanism is still used.

[0118] In another example, considering that MPE-induced power backoff occurs under specific circumstances, an additional UL (uplink) beam reporting triggered by the terminal device is added, i.e., triggered uplink beam reporting.

[0119] like Figure 3 As shown, taking the reporting of CRI / SSBID and L1-RSRP as an example, firstly, when the "decision mechanism" takes effect, the terminal device reports a trigger signaling to the base station in the MAC CE or in the PUCCH.

[0120] Then, the base station configures the SSB / CSI-RS for UL beam measurement and sends it to the terminal device.

[0121] Secondly, the terminal equipment performs beam measurement based on SSB / CSI-RS and takes into account the power back-off caused by MPE, and reports one or N (an integer greater than 1) CRI / SSBID+L1-RSRP suitable for UL transmission.

[0122] Furthermore, the base station will use SSBID / CRI (and...) Figure 3 The SSB-Index / CSI-RS-Index correspondences are configured in the spatialrelationinfo to indicate the beam direction of the uplink PUCCH / SRS (Sounding Reference Signal).

[0123] By the information reporting method of the embodiment of the application, the problem of uplink beam selection in the case of power backoff caused by MPE is solved, and the uplink transmission performance is improved.
