Problems solved by technology

Therefore, the UE cannot detect the downlink control information (DCI) from the unreachable TRP
In addition, the user equipment still needs to activate an antenna panel (antenna panel) to receive the signal from the TRP that cannot be connected, thus causing a waste of power

Embodiment Construction

[0057] What is described in this chapter is the best way to implement the present invention, and the purpose is to illustrate the spirit of the present invention rather than to limit the protection scope of the present disclosure. The protection scope of the present invention should be defined by the appended claims.

[0058] In an embodiment of the present invention, a beam failure detection reference signal (beam-failure-detection reference-signal, BFD-RS) described in the present invention may be a channel state information reference signal (channel state information RS, CSI-RS) , a synchronization signal block (synchronization signal block, SSB), a demodulation reference signal (demodulation RS, DM-RS) or a sounding reference signal (sound RS, SRS), but the present invention is not limited thereto.

[0059] In the embodiment of the present invention, the index (index) or identification code (identity) mentioned in the present invention can be CORESETPoolIndex, TRP_ID, candi...

Abstract

The invention provides user equipment for beam fault detection. The user equipment can comprise a wireless radio frequency signal processing device and a processor. The radio frequency signal processing device estimates the first radio link quality according to a first beam fault detection reference signal set including at least one reference signal. The processor is coupled to the radio frequency signal processing device, and when the first radio link quality is lower than a critical value, the processor generates a first indication, wherein the first indication is a first beam failure instance or the first beam failure detection reference signal set. In addition, the processor starts a first timer and a first counter according to the first instruction.

Description

technical field [0001] Embodiments of the present invention are mainly related to a beam failure detection (beam failure detection, BFD) technology, especially related to beam failure reporting for multi-transmission / reception points (multi-TRP) operation technology. Background technique [0002] In the current 3rd Generation Partnership Project (3 rd - Under the specifications for New Radio (NR) mobile communication in Generation Partnership Project (3GPP), when a serving beam cannot be obtained, the user equipment (UE) can select another beam from the candidate beam list. The above operations will involve beam failure detection (beam failure detection, BFD) and beam failure recovery (beam failure recovery, BFR). [0003] However, when the BFR procedure is applied to multi-transmission / reception points (multi-TRP) operations, when a control beam of a TRP fails, the BFR procedure cannot be triggered. That is, the BFR procedure is triggered in multi-TRP operation only when...
