Abstract: Disclosed are methods and apparatus for multiplexing NACK-only HARQ feedback. A terminal device in a communication network may comprise at least one processor and at least one memory having computer program code stored thereon. The at least one memory and the computer program code may be configured, with the at least one processor, cause the terminal device to perform: receiving, from a network device, one or more uplink control channel configurations for transmitting HARQ feedback for multicast transmission of one or more services; receiving, from the network device, the multicast transmissions of the one or more services; converting HARQ feedback bits of the HARQ feedback for the multicast transmissions of the one or more services; multiplexing the converted HARQ feedback bits into a multiplexed HARQ feedback; selecting a physical uplink control channel (PUCCH) resource for transmission of the multiplexed HARQ feedback; and transmitting the multiplexed HARQ feedback using the selected PUCCH resource.

Abstract: Various example embodiments relate to devices, methods, apparatuses and computer readable mediums for cell discontinuous transmission or reception. A terminal device may receive a cell configuration for discontinuous transmission or reception from a network device. The configuration may define a discontinuous transmission or reception pattern including an active period and a non-active period, a first periodicity for transmission or reception during the active period, and a second periodicity for transmission or reception during the non-active period. When the discontinuous transmission or reception is activated, the terminal device may perform reception or transmission of a signal or channel in the first periodicity during the active period, and perform reception or transmission of the signal or channel in the second periodicity during the non-active period.

Abstract: Example embodiments of the present disclosure relate to polling a device for multicast broadcast service interest indication. A first device receives, from a second device, a physical downlink control channel (PDCCH) order addressed by a paging radio network temporary identifier for the first device. The PDCCH order comprises a request for an indication that at least one multicast broadcast service is to be received by the first device. The first device transmits, to the second device, a random access preamble associated with the at least one multicast broadcast service as a response to the request. Through this solution, the first device that monitors the single PDCCH order may have less power consumption.

Abstract: Embodiments of the present disclosure relate to a method, device, apparatus and computer readable medium for sidelink transmission. According to embodiments of the present disclosure, a first device determines a target transmission start position from a set of candidate transmission starting positions in a sidelink slot based on an access level of a sidelink transmission to be performed. The first device performs a LBT before the target transmission starting position. If the LBT is successful, the first device performs the sidelink transmission from the target transmission starting position. In this way, it enables the use on Mode 2 in shared/unlicensed spectrum, while addressing the issues of un-sensed (not detected) SPS transmissions due to LBT failure as well as making mode 2 more robust towards LBT failures due to other coexisting systems.

Abstract: Example embodiments of the present disclosure are related to state transition of a cell. An apparatus receives a monitoring occasion configuration for control information related to a discontinuous operation pattern of a cell, the monitoring occasion configuration indicating at least one monitoring occasion that is before activation of the discontinuous operation pattern or during a time when the discontinuous operation pattern is activated. The apparatus monitors the control information from the device at the at least one monitoring occasion, the control information at least indicating a state transition of the cell between an active state and a non-active state; and based on receiving the control information from the device, and determines, from the control information, the state transition of the cell between the active state and the non-active state.
