Abstract: Example embodiments of the present disclosure relate to an effective mechanism for reference signal (RS) configuration. In this solution, the terminal device determines at least one cyclic shift (CS) for an SRS transmission with four antenna ports, the at least one CS comprising: at least one first CS and at least one second CS, where the at least one second CS is different from the at least one first CS. Further, the terminal device transmits, to a network device and based on the at least one first CS and the at least one second CS, the SRS transmission over a comb-structure resource with a comb value of eight. In this way, the peak to average power ratio (PAPR) performance is improved.

Abstract: Embodiments of the present disclosure relate to communication. According to embodiments of the present disclosure, a first terminal device receives a configuration of a sidelink transmission from a network device. The configuration indicates a start symbol for the sidelink transmission. The first terminal device performs the clear channel assessment for the sidelink transmission. If the CCA is successful, the first terminal device transmits a sidelink signal based on a length between a completion of the CCA and the start symbol. In this way, it improves resource efficiency. It can also improve access ability.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. A terminal device receives, from a network device, a first downlink transmission on a first cell in a cell group; and determines, from a set of cells for uplink control transmissions associated with the cell group, a second cell for a first uplink control transmission for a first HARQ feedback for the first downlink transmission. In this way, a latency for HARQ feedback can be reduced.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. A terminal device transmits uplink data in an inactive state to a network device, and if a resume of a connection with the network device is to be performed at a cell where the transmission has been performed, the terminal device performs the resume of the connection by at least one of the following: maintaining, in a PDCP re-establishment, a state variable of PDCP entities of UM DRBs or SRBs; or at least one of initiating a PDCP recovery for at least DRBs supporting a transmission in the inactive state or discarding PDCP SDUs and PDCP PDUs for SRBs supporting a transmission in the inactive state. In this way, security during a SDT procedure can be enhanced.

Abstract: Embodiments of the present disclosure provide a solution for sidelink communications. In a method for communications, in accordance with a determination that a communication between a first terminal device and a second terminal device is in a power saving mode, the first terminal device determines a first candidate resource set from a resource pool for the first terminal device. The first candidate resource set is mapped to a first feedback occasion for the second terminal device. The first terminal device transmits, to the second terminal device, first data on a first resource of the first candidate resource set. The first terminal device then receives, from the second terminal device, a first feedback message to the first data during the first feedback occasion. Embodiments of the present disclosure provide a sidelink feedback mechanism on the PSFCH, which is especially friendly to power saving terminal devices. With the proposed feedback mechanism, a tradeoff between the power consumption and the time sensitive requirements of the terminal devices can be achieved, while the conflict of power selection in the sidelink resource pool can be avoided.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. A network device transmits, to a terminal device, a configuration of bandwidth part for transmission of uplink data in an inactive state, the configuration comprising a configured grant. When the terminal device decides to transmit the uplink data in the inactive state, the terminal device determines the configured grant from the configuration of bandwidth part, and transmits, in the inactive state, the uplink data to the network device based on the configured grant. In this way, configuration grant based small data transmission can be enhanced.

Abstract: Embodiments of the present disclosure relate to communication. According to embodiments of the present disclosure, a network device is able to configure resources dedicated to repetition of transmission during the access procedure. If a terminal device determines to perform the repetition of transmission, the terminal device uses the dedicated resources for the transmission. The numbers of the repetition are determined based on a target power for the transmission and a maximum power at the terminal device. In this way, it improves coverage of the terminal device and the success in accessing channel.
