Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present inventionIn attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is onlyIt is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skillPersonnel's every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
The embodiment of the present invention provides a kind of beam information report method, as shown in Figure 1, which comprises
S11, terminal detect whether that the failure of partial service wave beam occurs.
Specifically, UE can detecte RSRP (Reference Signal Receiving Power, the reference of served beamsSignal reception power) whether it is less than RSRQ (the Reference Signal of predetermined power threshold value or detection service wave beamReceiving Quality, Reference Signal Received Quality) whether it is less than predetermined quality threshold, if having detected served beamsRSRP be less than predetermined power threshold value or detect served beams RSRQ be less than predetermined quality threshold, then determination unit sub-serviceBusiness wave beam failure.
S12, when detecting that terminal reports unsuccessfully the related letter of wave beam to network side when the failure of partial service wave beam occursBreath.
Wherein, the relevant information of the failure wave beam includes unsuccessfully the beam index of wave beam, and the beam index specifically may be usedFor SS block (Synchronization Signal block, synchronization signal block) index, CSI-RS (Channel StateInformation Reference Signals, channel state information reference signals) resource or port index, indicate this waveThe configuration information of beam is numbered.
Further, the relevant information of the failure wave beam may also include unsuccessfully the RSRP information of wave beam.
Further, when detecting that partial service wave beam, which occurs, to fail, terminal can also be reported to network side and be foundNew candidate beam information.Wherein, the new candidate beam information can be terminal and be based on CSI-RS or synchronization signal blockIt was found that.
Optionally, the new candidate beam information may include the beam index of new candidate beam, the beam indexFor synchronization signal block index, CSI-RS resource or port index.
Further, the new candidate beam information may also include the RSRP information of new candidate beam.
Optionally, terminal based on network side configuration or itself can determine, report 1 to network side or N number of foundNew candidate beam information, wherein N is natural number greater than 1.Preferably, N is equal to the wave beam for the failure that terminal reportsNumber.
Beam information report method provided in an embodiment of the present invention, when detecting that partial service wave beam, which occurs, to fail, toThe new candidate beam information that network side reports unsuccessfully the relevant information of wave beam and found, so that network side is according to failure waveThe relevant information of beam rapidly carries out beam switchover, and updates served beams set, and compared with prior art, the present invention can be kept awayExempt from or reduce the wave beam managing process that network side triggers to keep the reliability of link, to reduce overhead.
The embodiment of the present invention also provides a kind of beam information reporting device, as shown in Fig. 2, described device includes:
Detection unit 11, for detecting whether the failure of partial service wave beam occurs；
Reporting unit 12, for when the detection unit 11 detect occur partial service wave beam failure when, to network sideReport unsuccessfully the relevant information of wave beam.
Wherein, the relevant information of the failure wave beam includes unsuccessfully the beam index of wave beam, and the beam index is to synchronizeBlock index, CSI-RS resource or port index, the configuration information number for indicating this wave beam.
Optionally, the relevant information of the failure wave beam further includes unsuccessfully the Reference Signal Received Power RSRP letter of wave beamBreath.
Further, the reporting unit 12 is also used to be reported to network side based on CSI-RS or the discovery of synchronization signal blockNew candidate beam information.
Wherein, the new candidate beam information includes the beam index of new candidate beam, and the beam index is sameWalk block index, CSI-RS resource or port index.
Optionally, the new candidate beam information further includes the RSRP information of new candidate beam.
Optionally, the reporting unit 12, for reporting one to network side based on network side configuration or itself decisionOr the new candidate beam information of multiple discoveries.
Preferably, the number for the new candidate beam information that the reporting unit 12 is reported to network side and the wave beam that failsNumber is equal.
Beam information reporting device provided in an embodiment of the present invention, when detecting that partial service wave beam, which occurs, to fail, toThe new candidate beam information that network side reports unsuccessfully the relevant information of wave beam and found, so that network side is according to failure waveThe relevant information of beam rapidly carries out beam switchover, and updates served beams set, and compared with prior art, the present invention can be kept awayExempt from or reduce the wave beam managing process that network side triggers to keep the reliability of link, to reduce overhead.
