It should be understood that the terms "system" and "network" are used interchangeably herein. The term "and/or" in this context is merely an association describing the associated object, indicating that there may be three relationships, for example, A and / or B, which may indicate that A exists separately, and both A and B exist, respectively. B these three situations. In addition, the character "/" in this article generally indicates that the contextual object is an "or" relationship.

In the New Radio (NR) multi-beam system, the entire cell can be covered by different beams, that is, each beam covers a smaller range, by sweeping over time. The effect of multiple beams covering the entire cell is achieved. Different beams are currently identified by different signals carried on them.

Optionally, different synchronization signals (Synchronization Signal Blocks, SS blocks, or SSBs) are transmitted on different beams, so different beams can be distinguished by different SS blocks.

Optionally, different channel state information reference signals (CSI-RSs) are transmitted on some different beams, and the UE identifies different beams by using CSI-RS signals/CSI-RS resources. Therefore, different beams can be distinguished by different CSI-RSs.

Optionally, some Beams transmit different SSBs, and other beams transmit different CSI-RSs. Therefore, different CSI-RSs, different SSBs, and different types of CSI-RSs and SSBs may be used. distinguish.

Optionally, in the embodiment of the present application, the signals are different, which may mean that the identification information that is visible to the signal is different.

The terminal device can measure the signal carried on the beam and report the corresponding measurement result to the network.

The UE needs to measure some signals in a multi-beam system, and based on the measurement results, it is judged which signals (or beams) have better transmission quality, and the related information (for example, which signal quality is better, and the corresponding measurement results) ) reported to the network. For example, from the measured N signals, the optimal K (1<=K<N) signals are selected for reporting.

Optionally, in the embodiment of the present application, the beam pair terminal device may be invisible, and the terminal may see different signal identifiers.

Optionally, when measuring, the terminal device can acquire the signal strength of the signal and is based on the signal strength Degree is judged.

Specifically, the reference signal receiving power (L1-RSRP) can be received by measuring the reference signal, and the RSRP is compared, and then the optimal K signals are selected for reporting.

Optionally, when measuring, the terminal device may adopt a block error rate (BLER), and determine, according to the BLER, where the BLER may be a physical downlink control channel (PDCCH). The BLER (Hypothetical PDCCH BLER) determines whether the quality of a beam carrying a PDCCH is good or bad.

Because the terminal device calculates the Hypothetical PDCCH BLER, it considers the interference it receives, and RSRP considers the strength of the received signal itself. Therefore, in this case, the two are not completely identical. For example, if a beam has a strong signal and the terminal equipment receives strong interference when receiving it, the result is the best if it is determined by RSRP, but the beam failure has been determined by the Hypothetical PDCCH BLER. Failed.

If the current working PDCCH beam(s) of the terminal device is determined to be a beam failure by the Hypothetical PDCCH BLER, the terminal device needs to measure some beams, and select one or more new candidates by using the measurement result. The new candidate beam (s) is reported to the network side. When selecting a new candidate beam, one way is to measure and select according to RSRP.

If the second method described above is used, a "ping-pong effect" may occur. For example, the current 2 beam (beam1 and beam2) signal energy is very good (assuming the best in the measured beam), but the interference is very large. Currently, the PDCCH is transmitted on the beam2 for the terminal device (ie, the beam 2 is the active PDCCH beam). When the terminal device determines to send the beam failure, the beam1 is selected for reporting; the network side transmits the beam 1 according to the report of the terminal device. At this time, the quality of the beam 1 as the active PDCCH beam is judged by the Hypothetical PDCCH BLER, and since the interference is large, it is determined to be beam failure. When beam is reselected, this beam2 is also selected, and beam 2 will also have beam failure. After selecting beam1, beam failure,... will occur again. Thus entering the "ping-pong effect."

Therefore, the embodiments of the present application provide a method for solving the ping-pong effect of beam selection due to using different measurement modes.

The method 200 is optionally applicable to the system shown in FIG. 1, but is not limited thereto. The method 200 can optionally be performed by a terminal device. The method 200 includes at least some of the following.

In 210, after determining, by the terminal device, that the signal quality of the first reference signal measured by the first measurement manner is poor to satisfy the first condition, the measurement result obtained by measuring the at least one reference signal based on the second measurement manner is from at least one Selecting a second reference signal from the reference signal, the signal quality of the selected second reference signal is excellent to satisfy the second condition, and the first event occurring for the second reference signal has met the third condition or for the The first event does not occur within a preset or configured range, wherein the first event is that the signal quality measured by using the first measurement mode is poor to satisfy the first condition.

The measuring the at least one reference signal based on the second measurement manner may be performed before determining that the signal quality of the first reference signal measured by the first measurement manner is poor until the first condition is met, and may also be determined by using the first measurement manner. The signal quality of the first reference signal is poor until the first condition is satisfied.

Optionally, the first reference signal is a channel state information reference signal or a synchronization signal block.

Optionally, the first condition may be that the signal quality of the first reference signal is lower than or equal to a specific value.

Alternatively, the first condition may be that the number of times the signal quality of the first reference signal is lower than or equal to the specific value is accumulated to a predetermined number of times.

Alternatively, the first condition may be that the number of times the signal quality of the first reference signal is continuously lower than or equal to the specific value is accumulated to a predetermined number of times.

Optionally, the at least one reference signal comprises a channel state information reference signal and/or a synchronization signal block.

Optionally, the at least one reference signal may also include a first reference signal.

Optionally, in the embodiment of the present application, the reference signals with different identifier IDs are sent by using different transmit beams.

Optionally, the second condition may be that the signal quality of the second reference signal is higher than or equal to a specific value.

Alternatively, the second condition may be that the number of times the signal quality of the second reference signal is higher than or equal to the specific value is accumulated to a predetermined number of times.

Alternatively, the second condition may be that the signal quality of the second reference signal is continuously higher than or equal to the specific value for a predetermined number of times.

In 220, the terminal device reports the selected second reference signal to the network device.

Specifically, the terminal device may report the second reference signal to the network device, and optionally, may carry the measurement result, and the network device may select, according to the reporting by the terminal device, the downlink channel corresponding to the second reference signal, for example, PDCCH.

In order to more clearly understand the present application, the third condition will be described below.

In one implementation, the third condition includes experiencing a time window after the first event occurs.

Optionally, at least one of a start position, an end position, and a time length of the time window is preset or configured by a network side.

For example, the network configures the UE to transmit its PDCCH on the current beam 0. At the same time, if beam failure occurs, the UE may measure N CSI-RS signals (the N CSI-RSs may include the CSI-RS corresponding to beam0 or may not include the CSI-RS corresponding to beam0) (eg, L1-RSRP), and select one of them as a new candidate beam to report to the network.

If beam failure occurs in beam 0, a time window is set. In this specified time window, the UE does not select beam 0 as the new candidate beam to report to the network.

The length of the time window is a value that can be configured by the network or preset on the UE.

The start or end position of this time window can be configured by the network or preset on the UE.

It should be understood that the above example is beam 0, and the same applies to the beam of N CSI-RS signals selected by the UE as the new candidate beam and finally as the active beam.

In one implementation, the third condition includes the number of times the second event occurs after the first event occurs is greater than or equal to a particular value.

Optionally, the second event is:

Performing a measured event using the first measurement method; or

If at the same time In the case of beam failure, the UE may measure N CSI-RS signals (the N CSI-RSs may include CSI-RS corresponding to beam0 or may not include CSI-RS corresponding to beam0) signal strength (eg, L1-RSRP) ), and select one of them as a new candidate beam to report to the network.

If beam failure occurs in beam 0, the UE will not select beam0 as the new candidate beam to report to the network within a certain number of times:

The above number of times can be configured by the network or preset on the terminal device.

Among them, the way of counting, you can have the following options:

When the UE selects a new candidate beam, the record is incremented by 1.

When the UE measures a certain number of measured values, the log is incremented by 1.

The above example is beam 0. The same applies to the beams of the N CSI-RS signals that are selected by the UE as the new candidate beam and finally as the active beam.

In the above embodiment, only the case of measuring for the CSI-RS signal is described, and the same applies to the SS block measurement, or the CSI-RS and the SS block are simultaneously measured.

The third condition is described above, including: experiencing a time window after the first event occurs, and the third condition includes: the number of times the second event occurs after the occurrence of the first event is greater than or equal to a specific value, which should be understood The third condition includes: the time window after the occurrence of the first event and the number of times the second event occurs after the first event occurs is greater than or equal to a specific value, that is, when the two conditions are met, The terminal device selects the beam corresponding to the second reference signal as a new candidate beam.
