Description

Information reporting and receiving method, terminal and network equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information reporting and receiving method, a terminal, and a network device.

Background

The flow of beam management is roughly as follows: 1) the method comprises the steps that a terminal receives configuration information of reference signals (CSI-RS and/or SSB) used for beam management and configuration information of CSI report sent by a base station; 2) a terminal measures received power (RSRP) of a reference signal for beam management; 3) the terminal reports according to the CSI reporting configuration, and the configuration information comprises the reported content, the reported type, the measured reference signal and the like; 4) and the base station selects a proper transmitting beam for communication according to the information reported by the terminal and indicates the transmitting beam information to the terminal.

The terminal can establish a communication link with a plurality of TRPs (Transmission Receive points) for data Transmission. Compared with single TRP transmission, the probability of communication interruption can be reduced when the terminal communicates with a plurality of TRPs, and robustness or reliability is improved. At present, it has been proposed to enhance the group-based beam reporting mode by means of reference signal configuration and the like, so that a terminal can distinguish RSs (reference signals) from two TRPs, and select a combination that can be used for multi-TRP transmission for reporting when reporting the group-based beam.

In the multi-TRP transmission mode, some non-ideal situations are not suitable for data transmission by using the multi-TRP mode.

When the reportQuantity in the configuration of the CSI report received by the terminal is 'CRI-RSRP' or 'ssb-Index-RSRP', the terminal reports a measured Index value (CRI) of a reference signal and a corresponding RSRP value. And when the reportQuantity is cri-SINR 'or ssb-Index-SINR', the terminal reports the Index value of the measured reference signal and the corresponding SINR value.

Further, when the value of nrofReportedRS or nrofReportedRSForSINR is greater than 1, or groupbasedbeamdreporting in the configuration of CSI report is 'enabled', the terminal reports the index values of two different reference signals according to the strength of L1-RSRP or L1-SINR and reports the corresponding RSRP/SINR values in a differential manner. The differential reporting is specifically divided into the following two cases:

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

L1-SINR report: L1-SINR maximum value quantization is 7bit, reporting range [ -23,40] dB, step length is 0.5 dB. The differential L1-SINR value is quantized to 4 bits, and the step size relative to the reported maximum value is 1 dB.

As shown in fig. 1, an information reporting method is provided, which is applied to a terminal and includes:

In the embodiment, the reference signal received power L1-RSRP or the signal-to-noise ratio L1-SINR of the L1 layer for beam management is reported in a differential mode, and the threshold value of the differential report of the L1-RSRP or the L1-SINR is predefined or configured by a network side. The method and the device can realize L1-RSRP or L1-SINR reporting which saves more bits than the existing group-based beam reporting or is more accurate under the same bit number overhead.

The network side configures in a way that a MAC-CE (medium access control-control element) activates one of the values through RRC (radio resource control) configuration or RRC configuration of an optional set.

Take the reported content of the terminal as L1-RSRP as an example (L1-SINR same principle). The set of L1-RSRP threshold values X of the reference signals of the two TRPs in the multi-TRP mode is configured to be {4dB, 6dB and 8dB } on the network side, and the MAC-CE signaling is activated by 6dB to serve as the threshold value. The step length Y reported in a differential mode is fixed to be 2 dB.

Two special states are considered: when the difference value of L1-RSRP of reference signals sent by the UE for measuring the TRP0 and the TRP1 is larger than X, reporting a special state 1;
