    Abstract: Embodiments of the present disclosure relate to method, device and computer readable medium for contention window adjustment. In example embodiments, a method includes selecting, at least from first transmissions in a first time interval, a set of reference transmissions based on occupancy of a set of subbands by the first transmissions, clear channel assessment being performed on the set of subbands. The method further includes determining an unsuccessful reception ratio based on reception states of the set of reference transmissions. The method further includes determining, based on the unsuccessful reception ratio, an adjustment on a contention window for a second transmission in a second time interval after the first time interval.

    Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for resource selection. In example embodiments, a method for resource selection includes selecting, at a first terminal device, a first resource for transmitting a first packet from a resource pool. The method further includes determining a second resource selected from the resource pool by a second terminal device for transmitting a second packet. The method further includes determining whether a first transmission priority associated with the first packet is lower than a second transmission priority associated with the second packet. The method further includes in response to determining that the first transmission priority is 10 lower than the second transmission priority, selecting an available resource from the resource pool to transmit the first packet.

    Abstract: Embodiments of the present disclosure relate to methods, devices and apparatus of resource mapping for data transmission and of data receiving. In an embodiment of the present disclosure, a carrier frequency band for the data transmission is divided into a plurality of sub-bandwidths, and the method may include mapping resource elements for the data transmission in an order of sub-bandwidths and mapping, in each of the plurality sub-bandwidths, the resource elements first in an order of frequency domain and then in an order of time domain. With embodiments of the present disclosure, new radio access system with wider bandwidth could co-exist well with other communication on unlicensed band like WiFi.

    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.

    Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable mediums for uplink transmission. In example embodiments, a method implemented at a terminal device is provided. The method comprises, in response to being configured with at least one SRS resource set by a network device and the at least one SRS resource set being associated with first and second CSI-RS resources, receiving, from the network device, a first CSI-RS transmitted via a first TRP over the first CSI-RS resource and a second CSI-RS transmitted via a second TRP over the second CSI-RS resource. The method further comprises determining, based on the received first and second CSI-RSs, first precoding information for uplink transmission via the first TRP and second precoding information for uplink transmission via the second TRP respectively. The method further comprises determining, from the first and second TRPs, at least one TRP for uplink transmission, the at least one TRP being associated with third precoding information selected from the first and second precoding information. In addition, the method further comprises transmitting, based on the third precoding information, at least one SRS to the network device via the at least one TRP.
