摘要： The present application discloses a beam recovery method for a multi-TRP system. The method is executed on a user equipment side, and comprises: when a beam failure event is detected, obtaining, by means of at least one preset dedicated SR resource, at least one PUCCH resource configured, the PUCCH resource being used for carrying the beam failure event for transmission; and selecting a report-receiving TRP and a first beam, and using the first beam to transmit the beam failure event to said TRP on the PUCCH resource to cause the base station to reconfigure a beam for transmission.

摘要： Disclosed is a transmitter for enhancing CSI reporting in multi-TRP/panel scenario. Several solutions are proposed to support A-CSI/SP-CSI reporting on PUSCH with repetition, which include activation and deactivation of CSI reporting, transmission occasion of SP-CSI reporting, and CSI reporting on PUSCH with repetition w/wo UL data. With the improvements, the support for A-CSI/SP-CSI reporting on PUSCH with repetition in multi-TRP/panel scenario is greatly enhanced.

摘要： Provided is a method for configuring TCI state in a multi-TRP system. The method comprises: acquiring PDCCH-related information according to a monitored search space and a corresponding control resource set (CORESET), wherein the CORESET is configured with one activated transmission configuration indicator (TCI) state or two active TCI states, and each active TCI state comprises a transmission beam-related parameter; and a UE receiving a PDCCH by using a reception beam corresponding to the TCI state. By means of the method, a UE can receive a PDCCH by flexibly using a reception beam corresponding to one active TCI state or reception beams corresponding to two active TCI states, depending on an implementation situation.
