For the ease of clearly describing the technical solution of the embodiment of the present invention, in an embodiment of the present invention, use " the One ", the printed words such as " second " distinguish function or the essentially identical identical entry of effect or similar item, and those skilled in the art can To understand that the printed words such as " first ", " second " are not defined quantity and execution order.
In the embodiment of the present invention, " illustrative " or " such as " etc. words for indicate make example, illustration or explanation.This hair Be described as in bright embodiment " illustrative " or " such as " any embodiment or design scheme be not necessarily to be construed as than it Its embodiment or design scheme more preferably or more advantage.Specifically, use " illustrative " or " such as " etc. words be intended to Related notion is presented in specific ways.In embodiments of the present invention, unless otherwise indicated, the meaning of " plurality " is refer to two or It is more than two.
Wave beam failure detection method provided in an embodiment of the present invention can be applied to wave beam failure recovery mechanism, can also answer During needing to carry out wave beam failure detection for other, the present invention is applicable in scene without limitation to specific.
Illustratively, in high band communication system, when communication disruption occurs, by the way of conventional wireless link re-establishment Restore to communicate, the used time is longer, therefore the prior art introduces wave beam failure recovery mechanism.Wave beam failure recovery mechanism is generally wrapped Include: wave beam failure detection, candidate beam identification send the request of wave beam failure recovery and receive wave beam and restores in response four Hold.Wherein, the wave beam failure detection process during wave beam failure recovery mechanism specifically includes: UE detects whole served beams PDCCH (or being serving PDCCH) on (serving beam), if UE detects that above-mentioned wave beam fails, it is determined that Wave beam turkey (beam failure event) has occurred.
During existing wave beam failure detection, CSI-RS or synchronization signal is can be used in wave beam failure detection reference signal Block (Synchronisation signal block, SSB) (SSB is alternatively referred to as: SS block).
Specifically, when use CSI-RS as wave beam failure detection reference signal to carry out wave beam failure detection when, be based on The process that CSI-RS carrys out calculation assumption PDCCH Block Error Rate (hypothetical PDCCH BLER) specifically includes following process:
1), UE carries out interference measurement and obtains jamming power.
2), UE measures CSI-RS to obtain the power for assuming PDCCH.
Specifically, UE obtains the Pc_PDCCH parameter of the CSI-RS as wave beam failure detection reference signal, then, according to Pc_PDCCH parameter calculates the power for assuming PDCCH indirectly.Wherein, the DMRS on above-mentioned CSI-RS and hypothesis PDCCH Spatially there is QCL.Above-mentioned Pc_PDCCH parameter are as follows: energy (the Energy per of each resource element of PDCCH Resource element, EPRE) ratio with the EPRE of non-zero power NZP (non-zero power) CSI-RS.Wherein, on The Pc_PDCCH parameter stated, which is the network equipment, is allocated to UE by high-level signaling, and Pc_PDCCH parameter value is 0dB.
It should be noted that above-mentioned Pc_PDCCH parameter, that is, power excursion (power between PDCCH and CSI-RS offset)。
Since the power of existing SSB is provided by SS-PBCH-BlockPower parameter, UE can basis Then SS-PBCH-BlockPower parameter is joined to obtain the power of SSB according to the power of the SSB got and Pc_SS Number, determines the power of CSI-RS, wherein Pc_SS parameter is the ratio of SSB EPRE and NZP CSI-RS EPRE, Pc_SS ginseng Number is the power excursion between SSB and CSI-RS, and the value range of the power excursion is [- 8,15] db, and has 1db step-length.It connects , the power of equivalent PDCCH is obtained according to the power of CSI-RS and Pc_PDCCH parameter.Wherein, SS-PBCH- BlockPower parameter is that the network equipment by high-level signaling is allocated to UE.
3), UE according to jamming power and assumes that the power meter of PDCCH calculates the SINR of hypothesis PDCCH.
4), UE calculates the Block Error Rate for assuming PDCCH according to the SINR for assuming PDCCH.
From the above process it is found that the corresponding Pc_SS parameter of different CSI-RS resource is different, therefore, when the network equipment is When UE configures multiple CSI-RS resource, since each CSI-RS resource respectively corresponds a Pc_SS parameter, and the network equipment is matched The DMRS spatially QCL for not being each CSI-RS resource in the multiple CSI-RS resource set and assuming on PDCCH, therefore, If UE is from the CSI-RS resource selected in multiple CSI-RS resource and assumes DMRS on PDCCH not spatially QCL, then Pc_SS parameter based on the CSI-RS resource then can not accurately calculate the Block Error Rate for assuming PDCCH, and eventually leading to can not Wave beam failure detection is carried out, or causes testing result inaccurate.
In addition, there is presently no effective when the network equipment is that UE configures SSB as wave beam failure detection reference signal Wave beam failure detection scheme.If not configuring CSI-RS resource for UE, UE can not be obtained by measurement SSB hypothetical PDCCH BLER。
In view of the above-mentioned problems, the embodiment of the present invention provides a kind of wave beam failure detection method, terminal and the network equipment, network Equipment is by sending SSB to terminal, and terminal obtains the power of the SSB after receiving the SSB, then, according to the power of SSB The Block Error Rate of the hypothesis PDCCH of the downlink wave beam is determined, finally, determining according to the Block Error Rate of the hypothesis PDCCH of downlink wave beam Whether the downlink wave beam fails.The terminal of that embodiment of the invention to carry out downlink wave beam by using the SSB that the network equipment issues Wave beam failure detection obtains the power for assuming PDCCH by the power and network configuration of SSB or predefined parameter, accurately Calculate assume PDCCH Block Error Rate, and then accurately to downlink wave beam carry out wave beam failure detection.
