    Abstract: This disclosure presents methods and processes to allow a user equipment (UE) to map a hybrid automatic retransmission request-acknowledgement (HARQ-ACK) feedback to one or more HARQ-ACK sub-codebooks for received services. The one or more HARQ-ACK sub-codebooks can be concatenated into one HARQ-ACK codebook and then communicated to a communication node, when those services use a HARQ-ACK feedback that is scheduled for the same time instance. Various methods can be used for the concatenation order depending on the number of multicast and broadcast services (MBS) for which HARQ feedback is to be provided, and depending on whether HARQ-ACK feedback is to be sent for unicast services at the scheduled time instance. The concatenation order can utilize an increasing order or a decreasing order of the concatenation order parameters.

    Abstract: Example embodiments of the present disclosure relate to applying timing advance during random access procedure. The first apparatus transmits, to a first apparatus, a channel state information (CSI) report configuration comprising a first sub-configuration and a second sub-configuration; and receives, from the first apparatus and based at least in part on the first and second first priority reporting levels, a CSI report associated with at least one of the first sub-configuration or the second sub-configuration. Impacts to the other CSI reporting caused by introducing the sub-configuration would be minimized.

    Abstract: The present disclosure relates to a first cell activation when the cell discontinuous transmission (DTX)/discontinuous reception (DRX) is applied. In particular, a network device transmits a configuration of cell DTX and/or a configuration of cell DRX for a first cell to a terminal device. The network device also transmits an activation indication for the first cell. The terminal device monitors a set of reference signals from the network device during an activation procedure of the first cell. The terminal device further transmits a report that is based on a measurement on the set of reference signals to a cell that is a special cell or a physical uplink control channel cell. In this way, it can reduce the latency of the activation of the first cell.

    Abstract: Example embodiments of the present disclosure relate to adjustment of contention window (CW) for listen before talk (LBT). A device determines a target size of a contention window for listen before talk at least in part based on at least one of a first metric and a second metric. The first metric indicates a level of intra-system activity of one of the plurality of systems. The second metric indicates a level of inter-system activity of the plurality of systems. The at least one of first and second metrics are determined by the device based on one or more messages in a set of resources shared by a plurality of systems. This solution enables the device to adjust the LBT by determining the target size of the contention window. By doing so, the device may determine an appropriate size of the contention window even when HARQ feedback is not available. In this way, a system may be able to coexist fairly with other systems in unlicensed spectrum.

    Abstract: Example embodiments of the present disclosure relate to sidelink (SL) transmission enhancement. A first device determines a channel occupancy time (COT) to be shared by the first device and at least one second device for transmissions on a shared radio frequency band; selects a first time slot during the COT for a transmission; and performs the transmission in the first time slot by extending the transmission to a first guard period of the first time slot or to a second guard period of a second time slot prior to the first time slot during the COT. By doing so, a channel access procedure requiring a smaller time gap between transmissions can be selected and performed, which can thus improve the flexibility of channel access procedures for SL transmission in the shared frequency band.

    Abstract: Embodiments of the present disclosure relate to a short control signaling transmission for sidelink communication in an unlicensed spectrum. According to one aspect of the present disclosure, if a control signaling is to be transmitted to a second device via a short control signaling transmission, a first device determines whether the short control signaling transmission is available based on at least information related to a counter, the counter being used for counting occasions within a period for the short control signaling transmission at a sidelink interface. If the short control signaling transmission is available, the first device transmits the control signaling to the second device on a first resource configured for the short control signaling transmission. In this way, constraints for the usage of the short control signaling transmission can be satisfied, and a reliable transmission of sidelink control signaling in the unlicensed spectrum can be achieved.
