Abstract

Apparatuses and systems for providing multiple structures to enable flexibility of a multiple transmission and reception point ultra-reliable low-latency communication (M-TRP URLLC) operation and reduce measurement effort and power consumption from a transceiving apparatus such as a UE are provided. The techniques disclosed here feature a transceiving apparatus including a transceiver and circuitry. The transceiver, in operation, receives signals from multiple transmission and reception points (M-TRPs) in a network on at least physical downlink shared channels (PDSCHs). The circuitry, in operation, performs beam failure recovery (BFR) by evaluating beam failure detection (BFD) and candidate new beam detection (CBD) for the signals from at least a first one of the M-TRPs. The signals from the first one of the M-TRPs comprise signals received on a physical downlink control channel (PDCCH), and the circuitry determines to skip evaluation of one or both of the BFD and the CBD for one or more additional ones of the M-TRPs in response to one or more conditions.

Claims (12)

1 . An integrated circuit comprising:

reception circuitry, which, in operation, controls a reception of a first set of beam failure detection (BFD) reference signal configurations, of a second set of BFD reference signal configurations, of a first set of candidate new beam detection (CBD) reference signal configurations, and of a second set of CBD reference signal configurations; and

performance circuitry, which, in operation, controls performance of a first BFD relating to a first transmission and reception point (TRP) based on the first set of BFD reference signal configurations, a second BFD relating to a second TRP based on the second set of BFD reference signal configurations, and at least one of a first CBD relating to the first TRP based on the first set of CBD reference signal configurations or a second CBD relating to the second TRP based on the second set of CBD reference signal configurations.

2 . The integrated circuit in accordance with claim 1 , wherein the first set of BFD reference signal configurations, the second set of BFD reference signal configurations, the first set of CBD reference signal configurations, and the second set of CBD reference signal configurations are indicated by a Medium Access Control Control Element (MAC CE) or a Radio Resource Control (RRC) signaling.

3 . The integrated circuit in accordance with claim 1 , wherein the first and second BFD reference signal configurations and/or the first and second CBD reference signal configurations include a configuration of a channel state information (CSI) reference signal and/or a configuration of a synchronization signal block (SSB).

4 . The integrated circuit in accordance with claim 1 , further comprising:

a transmission circuitry, which, in operation, controls reporting, to a base station, of content including at least one result of the first BFD and at least one result of the second BFD.

5 . The integrated circuit in accordance with claim 1 , wherein whether both of the first BFD based on the first set of BFD reference signal configurations and the second BFD based on the second set of BFD reference signal configurations are performed is determined by a transmission configuration indication (TCI) state of downlink control information (DCI).

6 . The integrated circuit in accordance with claim 1 , further comprising:

a transmission circuitry, which, in operation, controls reporting, to a base station, of content including one result of the first BFD relating to the first set of BFD reference signal configurations or the second BFD relating to the second set of BFD reference signal configurations, and one result of the first CBD relating to the first set of CBD reference signal configurations or the second CBD relating to the second set of CBD reference signal configurations.

7 . The integrated circuit in accordance with claim 1 , further comprising:

a transmission circuitry, which, in operation, controls reporting, to a base station, of content including at least one result of the first BFD or the first CBD and at least one result of the second BFD or the second CBD.
