    摘要: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for reporting, from a user equipment (UE), beam failure recovery (BFR) information for multiple transmission and reception points (TRPs) via a BFR medium access control (MAC) control element (MAC-CE) in multi-TRP deployment scenarios. In some aspects, the UE may monitor a beam failure status for each of a first TRP and a second TRP and may transmit a BFR MAC-CE if the UE detects a beam failure for the first TRP or the second TRP. The UE may include, in the BFR MAC-CE, a status indicator field that indicates the beam failure status for each of the first TRP and the second TRP and whether a candidate reference signal is reported for identified TRPs of the first TRP and the second TRP for which a beam failure is detected.

    摘要: Embodiments of the present application relate to methods and apparatuses for a transmission reception point (TRP) related beam failure detection and recovery procedures under a 3rd Generation Partnership Project (3GPP) 5G system or the like. According to an embodiment of the present application, a method can be performed by a user equipment (UE) and include: receiving, from a serving cell, configuration information related to at least one transmission reception point (TRP) of the serving cell; detecting a beam failure of a TRP; and triggering a beam failure recovery (BFR) procedure, wherein the BFR procedure includes transmitting a BFR request to the serving cell, and wherein the BFR request includes information per TRP associated with the at least one TRP of the serving cell. If the configuration information is related to at least two TRPs of the serving cell, before transmitting the BFR request, the UE may detect a further beam failure of a further TRP. The UE may trigger a further BFR procedure.

    摘要: A wireless device receives one or more configuration parameters indicating a first beam detection set including a first reference signal and a second beam detection set including a second reference signal. The first reference signal overlaps in at least one symbol with the second reference signal. The wireless device measures, for beam failure and in response to the first beam detection set being different from the second beam detection set, both the first reference signal and the second reference signal.

    摘要: Embodiments of the present application are related to a method and apparatus for beam determination. An exemplary method includes: receiving configuration information at least indicating two failure detection resource sets in a cell; transmitting failure recovery information at least indicating a radio link quality of all failure detection resources in a first failure detection resource set of the two failure detection resource sets is worse than a first threshold; and monitoring physical downlink control channels (PDCCH)s in a control resource set (CORESET) in the cell based on the failure recovery information, wherein one or more transmission configuration indicator (TCI) states are activated for the CORESET and one TCI state of the one or more TCI states is associated with the first failure detection resource set, after a number of symbols from a last symbol of a received PDCCH for confirming the failure recovery information.

    摘要: The aspects described herein may improve beam management at an apparatus (e.g., a UE) by allowing the apparatus to proactively transmit a beam report including information that may avoid a full beam failure recovery (BFR) procedure at the apparatus. The apparatus receives a set of beam failure detection reference signals and transmits a beam report indicating a partial beam failure when a radio link quality of at least a first beam failure detection reference signal in the set of beam failure detection reference signals is less than a quality threshold and a radio link quality of at least a second beam failure detection reference signal in the set of beam failure detection reference signals is greater than or equal to the quality threshold.
