Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to an information reporting and receiving method, terminal, and network device. Background Technology

[0002] The beam management process is roughly as follows: 1) The terminal receives the configuration information of the reference signal (CSI-RS and / or SSB) and the CSI report sent by the base station for beam management; 2) The terminal measures the received power (RSRP) of the reference signal used for beam management; 3) The terminal reports according to the CSI reporting configuration, which includes the content of the report, the type of report, and the reference signal measured; 4) The base station selects a suitable transmission beam for communication based on the information reported by the terminal and instructs the terminal on the transmission beam information.

[0003] The terminal can establish communication links with multiple Transmission Receive Points (TRPs) for data transmission. Compared with single TRP transmission, communication between the terminal and multiple TRPs reduces the probability of communication interruption and improves robustness and reliability. Current research has proposed enhancing group-based beam reporting through methods such as reference signal configuration, enabling the terminal to distinguish RS (Reference Signals) from two TRPs and select the appropriate combination for multi-TRP transmission during group-based beam reporting.

[0040] Figure 1 This is a flowchart illustrating the information reporting method according to an embodiment of the present invention;

[0041] Figure 2 This is a flowchart illustrating the information receiving method according to an embodiment of the present invention. Detailed Implementation

[0042] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0043] When the terminal receives a CSI report with reportQuantity configured as 'cri-RSRP' or 'ssb-Index-RSRP', the terminal reports the index value (CSI-RS resource indicator, CRI) of the measured reference signal and the corresponding RSRP value. When reportQuantity is 'cri-SINR' or 'ssb-Index-SINR', the terminal reports the index value of the measured reference signal and the corresponding SINR value.

[0044] Furthermore, when the value of nrofReportedRS or nrofReportedRSForSINR is greater than 1, or when groupBasedBeamReporting is 'enabled' in the CSIreport configuration, the terminal reports the index values ​​of two different reference signals based on the strength of L1-RSRP or L1-SINR and reports the corresponding RSRP / SINR values ​​differentially. Differential reporting specifically falls into the following two categories:

[0045] L1-RSRP reporting: The maximum value of L1-RSRP is quantized to 7 bits, with a reporting range of [-140, -44] dBm and a step size of 1 dB. The differential L1-RSRP value is quantized to 4 bits, with a step size of 2 dB relative to the reported maximum value.

[0046] L1-SINR reporting: The maximum L1-SINR value is quantized to 7 bits, with a reporting range of [-23, 40] dB and a step size of 0.5 dB. The differential L1-SINR value is quantized to 4 bits, with a step size of 1 dB relative to the reported maximum value.

[0047] like Figure 1 As shown, an information reporting method is provided, applied to a terminal, including:

[0048] Step 11, in group-based beam reporting, the L1 layer reference signal received power L1-RSRP or signal-to-noise ratio L1-SINR used for beam management is reported differentially / in special states. The threshold value for differential reporting of L1-RSRP or L1-SINR is predefined or configured on the network side.

[0049] This embodiment reports the L1-RSRP (Reference Signal Received Power) or L1-SINR (Signal-to-Noise Ratio) for beam management differentially, with threshold values ​​for differential reporting of L1-RSRP or L1-SINR predefined or configured on the network side. This achieves L1-RSRP or L1-SINR reporting that is more bit-efficient or more accurate than existing group-based beam reporting with the same bit-to-number overhead.

[0050] In an optional embodiment of the present invention, the step size of the L1-RSRP or L1-SINR differential reporting is predefined or configured on the network side. The number of bits reported by the L1-RSRP or L1-SINR differential reporting is determined based on the threshold value, the step size, and the number of reported states.

[0051] In an optional embodiment of the present invention, the number of bits reported differentially by L1-RSRP or L1-SINR is predefined or configured on the network side. The step size of the differential reporting by L1-RSRP or L1-SINR is determined based on the threshold value, the number of bits reported differentially, and the number of reported states.

[0052] In an optional embodiment of the present invention, the information reporting method may further include: when the terminal reports the difference status of L1-RSRP or L1-SINR as a special status, receiving an uplink grant sent by the network device; and reporting other information according to the uplink grant.

[0053] In the above embodiments of the present invention, the special state includes at least one of the following:

[0054] The first special state is when the differential reporting of L1-RSRP or L1-SINR of the reference signals transmitted by the terminal at the first and second transmission points is greater than the threshold value; or...

[0055] The second special state is the state in which the differential reporting of the L1-RSRP or L1-SINR of the reference signal sent by the first transmission point and the second transmission point in N consecutive measurements is greater than the threshold value.

[0056] Implementation Example 1:

[0057] The predefined threshold value X and the differential reporting step size Y are either predefined or configured on the network side. The network side is configured via RRC (Radio Resource Control) or by configuring an optional set of RRC values, with MAC-CE (Media Access Control-Control Unit) activating one of these values.

[0058] Taking L1-RSRP as an example of terminal reporting content (L1-SINR is similar). On the network side, in multi-TRP mode, the set of L1-RSRP threshold values ​​X for the reference signals of the two TRPs is configured as {4dB, 6dB, 8dB}, with MAC-CE signaling activation at 6dB as the threshold. The differential reporting step size Y is fixed at 2dB.

[0059] Consider two special states: when the difference between the L1-RSRP of the reference signals sent by TRP0 and TRP1 is greater than X, special state 1 is reported.

[0060] When the difference between the L1-RSRP of the reference signals sent by TRP0 and TRP1 in N consecutive measurements (N is predefined or configured by the network side) is greater than X, the UE reports special state 2.

[0061] The reported status includes four states: the difference between the L1-RSRP of the two reference signals sent by the terminal and the TRP, which are 0, 2, 4, and 6, and two special states, for a total of 6 states. Therefore, the number of bits reported differentially is 3.

[0062] The specific reporting content and its corresponding meanings are as follows:

[0063] Reporting bits meaning 000 The power difference is 0dB 001 The power difference is 2dB 010 The power difference is 4dB 011 The power difference is 6dB 100 Special condition 1: Power difference greater than 6dB 101 Special condition 2: Power difference greater than 6dB in N consecutive measurements 110 / 111 Other illegal statuses

[0064] Implementation Example 2:

[0065] Taking L1-RSRP as an example (L1-SINR is similar). The network side is configured with a 6dB L1-RSRP threshold value for the reference signals of the two TRPs in multi-TRP mode. The number of bits for differential reporting is predefined or configured to be 3. Considering the two special states in Example 1, the step size for differential reporting is 6 / 5 = 1.2dB.

[0066] The specific reporting content and its corresponding meanings are as follows:

[0067] Reporting bits meaning 000 The power difference is 0dB 001 The power difference is 1.2 dB. 010 The power difference is 2.4 dB. 011 The power difference is 3.6 dB. 100 The power difference is 4.8 dB. 101 The power difference is 6dB 110 Special condition 1: Power difference greater than 6dB 111 Special condition 2: Power difference greater than 6dB in N consecutive measurements

[0068] In the above embodiments of the present invention, the number of bits reported differentially in group-based beam reporting can be determined based on a threshold value and a step size, or the step size can be determined based on a threshold value and the number of bits reported differentially, so as to achieve L1-RSRP or L1-SINR reporting that saves more bits than existing group-based beam reporting or is more accurate under the same bit overhead.

[0069] Furthermore, the above embodiments of the present invention can help the network side identify scenarios where the UE has poor channel conditions with a certain TRP, making multi-TRP difficult. The network side can re-initiate beam measurement based on the UE's report. If the UE's measurement results fail to meet the conditions for N consecutive times, the UE can trigger beam failure recovery for that TRP.

[0071] Step 21, in group-based beam reporting, the receiving terminal reports the L1 layer reference signal received power L1-RSRP or signal-to-noise ratio L1-SINR for beam management in a differential manner / special state. The threshold value for differential reporting of L1-RSRP or L1-SINR is predefined or configured on the network side.

[0072] Optionally, the step size of the L1-RSRP or L1-SINR differential reporting and / or the number of bits of the L1-RSRP or L1-SINR differential reporting can be configured for the terminal.

[0073] Optionally, the information receiving method further includes: determining the number of bits for differential reporting of L1-RSRP or L1-SINR based on the threshold value, the step size, and the number of reported states.

[0074] The step size of the L1-RSRP or L1-SINR differential reporting is determined based on the threshold value, the number of bits reported differentially, and the number of reported states.

[0075] Optionally, the information receiving method further includes: sending an uplink grant to the terminal when the terminal reports a special state for the difference between L1-RSRP and L1-SINR; and receiving other information reported by the terminal based on the uplink grant.

[0076] The special state includes at least one of the following:

[0078] The second special state is the state when the difference between the L1-RSRP or L1-SINR of the reference signals sent by the first transmission point and the second transmission point in N consecutive measurements reaches the threshold value.
