A wireless device receives receive, from a base station, radio resource control messages comprising configuration parameters of a first semi-persistent scheduling (SPS) for multicast and broadcast services (MBS), wherein the configuration parameters of the first SPS comprise a first hybrid automatic repeat request acknowledgment (HARQ-ACK) codebook index. The wireless device receives a multicast transport block (TB) based on receiving a group common downlink control information (DCI) indicating an activation of the first SPS. The wireless device transmits first feedback for the multicast TB in a first HARQ-ACK codebook, of HARQ-ACK codebooks, indicated by the first HARQ-ACK codebook index.

A resource selection method and apparatus, and an electronic device, are provided. The resource selection method includes: performing, by a sending terminal, any one of the following operations on periodic resources selected and/or reserved by the sending terminal: performing resource selection re-evaluation on the periodic resources in a case that a preset re-evaluation condition is met; using an independent parameter for resource pre-emption detection of the periodic resources in a case that a preset resource pre-emption detection condition is met; releasing the periodic resources and/or performing resource re-selection from the periodic resources in a case that a preset resource selection triggering condition is met; and excluding the periodic resources from a candidate resource set in a case that a preset resource exclusion condition is met.

Methods, systems, and devices for wireless communications are described. A transmitting device and a receiving device may communicate sidelink messages of a second radio access technology (RAT) using a sidelink resource pool signaled using a first RAT. For example, the receiving UE may receive a sidelink control channel associated with the first RAT (e.g., Long Term Evolution (LTE)), may determine a set of time and frequency resources indicated by the sidelink control channel, and then may monitor the set of time and frequency resources to receive a sidelink message associated with the second RAT (e.g., New Radio (NR)). In some implementations, the set of time and frequency resource may be indicated that they may be used for the second RAT via a field in the sidelink control channel or via an additional sidelink message associated with the second RAT transmitted with the sidelink control channel.

This disclosure provides a codebook feedback processing method, a device, an apparatus and a medium. The method includes: determining, by a terminal, based on a quantity of repeated transmissions of a repeatedly transmitted semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH), whether there is at least one valid transmission in corresponding transmission opportunities; and determining, by the terminal, based on whether there is at least one valid transmission, whether a feedback bit position is reserved for the SPS PDSCH in a feedback codebook. A base station determines, based on whether there is at least one valid transmission, whether a feedback bit position is reserved for the SPS PDSCH in the feedback codebook.

A user equipment may receive a configuration message comprising at least one of: a configured grant configuration, or a semi-persistent scheduling configuration, wherein configuration may be associated with a cross-division duplexing slot format, wherein the cross-division duplexing slot format may comprise at least one of: a cross-division duplexing time slot for concurrent transmission in a plurality of communication directions, or a cross-division duplexing time slot for transmission in one communication direction; receive an information indicating at least one resource of the configuration; determine whether the at least one resource is valid, based on a comparison between a corresponding cross-division duplexing slot format of the at least one resource and the cross-division duplexing slot format associated with the configuration; and perform communication with the network device on the at least one resource based, at least partially, on a determination that the at least one resource is valid.

Various aspects include a method for preserving a msg3 transmission. The method may include receiving, by a UE device, from a base station, a CI that overlaps with the msg3 transmission. Responsive to receiving the CI, the msg3 transmission is not canceled. Another method disclosed herein includes continuing an RA procedure. The method may include encoding a first part of the msgB. The method may include encoding a second part of the msgB. The method may include attempting to decode, by the UE device, the first part of the msgB. The method may include attempting to decode, by the UE device, the second part of the msgB. Based on successfully decoding of the first part of the msgB, and unsuccessfully decoding of the second part of the msgB, the method may include continuing the RA procedure.
