    Abstract: 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.

    Abstract: A feedback method and apparatus which are used to provide a feedback mechanism in a sidelink communications system, and may be applied to the internet of vehicles, for example, V2X, LTE-V, and V2V. The method includes: a first terminal device determines that a feedback condition is met, and sends feedback information to a second terminal device, where the feedback information includes at least one of channel state information and a receive response, and the receive response includes a positive acknowledgment, a negative acknowledgment, or discontinuous transmission. In this way, the feedback condition is set, so that the first terminal device sends the feedback information only when the feedback condition is met. In this way, resource overheads and information redundancy that are caused when each terminal device in a communication group sends feedback information are effectively avoided.

    Abstract: Proposed are a method by which a first device performs wireless communication, and an apparatus supporting same. The method may comprise the steps of: acquiring an SL DRX configuration including an SL DRX inactivity timer, an SL DRX HARQ RTT timer, and an SL DRX retransmission timer, receiving, from a second device through a first PSCCH, first SCI for scheduling of a first PSSCH and second SCI; and receiving the second SCI and a first MAC PDU from the second device through the first PSSCH. For example, the first device may start the SL DRX inactivity timer. For example, the first device may transmit SL HARQ feedback information to the second device through a PSFCH on a PSFCH resource determined on the basis of a slot index and a sub-channel index related to the first PSSCH. For example, the first device may restart the SL DRX inactivity timer after the PSFCH resource on the basis of the second SCI being related to a groupcast.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE), such as a vehicle UE may receive an indication of a change in a formation of a vehicle grouping, such as a platoon, with which the UE is associated, the vehicle grouping including a plurality of vehicles moving as a group based on sidelink communications between members of the group. The UE may determine a distance-based feedback procedure to be used by the UE based on whether the UE is, as a result of the change in the formation, a primary vehicle in the vehicle grouping or a secondary vehicle that is responsive to one or more primary vehicles in the vehicle grouping, and may operate in accordance with the distance-based feedback procedure.
