Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a method, an apparatus, and a terminal for processing a detection failure.
Background
A network side may configure a reference signal resource corresponding to a downlink control (or data) channel or an uplink control (or data) channel of a terminal (User Equipment, UE), where the reference signal resource is used to identify a spatial relationship (or characteristic) of the corresponding channel. The reference signal resource indicates a state identifier (e.g., a TCI state ID) of a specific Transmission Configuration Indicator (TCI) for a downlink channel, and indicates a specific resource identifier for an uplink channel. Wherein the reference signal type comprises at least one of:
a Synchronous Signal Block (SSB);
channel State Information-Reference Signal (CSI-RS).
The network side may change a specific Channel (e.g., a Physical Downlink Control Channel (PDCCH), a Physical Downlink Shared Channel (PDSCH), a Physical Uplink Control Channel (PUCCH), a Physical Uplink Shared Channel (PUSCH)) of the UE through a Control signaling (e.g., a Radio Resource Control (RRC) message, or a MAC Control Element (MAC CE), or Downlink Control Information (DCI)). In the process of changing the service beam, the UE needs to detect a target signal (i.e., a target spatial relationship reference signal), and when the UE detects that the target signal meets the requirement according to the requirement specified by the protocol (e.g., the measurement value of the reference signal exceeds a certain signal strength or a signal quality threshold), the UE changes the spatial relationship reference signal of its specific control channel to the target signal.
When the UE changes the reference signal (e.g., RS for TCI state) of its specific channel, the target signal may not be transmitted due to frequency congestion, which may result in that the UE cannot normally change its operating reference signal, and thus, fails to transmit and receive data or control signaling.

In a 5G system, to transmit and receive data using a New air interface-unlicensed (NR-U) frequency band, a signal transmitting end needs to satisfy a usage rule of the unlicensed frequency band. For an unlicensed frequency band, a transmitting end needs to monitor whether the frequency band is occupied (or idle) before transmitting a signal, and if the frequency band is not occupied (or idle), the transmitting end may transmit the signal. If the band is occupied, the UE cannot transmit signals (i.e., Listen-Before-Talk (LBT) fails). According to the usage rule of the unlicensed frequency band, the UE needs to perform LBT in a specific frequency range (e.g., frequency sub-band), and only in the specific frequency range, if no signal transmission is monitored, the UE can perform signal transmission. In 5G systems, 1 specific BWP (or cell) may be configured with multiple frequency sub-bands.

In the embodiment of the application, after an event that triggers the terminal to detect the target signal occurs, the terminal detects the target signal, and if the target signal is not detected according to the conditions configured by the network side or agreed by the protocol, the terminal triggers a failure recovery process. By the technical scheme of the embodiment, the failure recovery process can be triggered by the terminal under the condition that the target signal is not detected, so that the terminal can recover the receiving and sending of data or signals as soon as possible, and the condition that the receiving and sending of the data or the control signaling are failed is avoided.
