Abstract: A method, device and computer readable medium for determining TA. A method includes, the network device (120) determines an estimation of a timing advance and an error of the timing advance based on a random access preamble received from the terminal device (110). The network device (120) determines different communication modes with different lengths of overheads for the terminal device (110) based on the error. The network device (120) may update the estimation of the timing advance based on feedback information from the terminal device (110). In this way, accuracy of the estimation of the timing advancing is improved.

Abstract: A method and an apparatus for a second user equipment, that causes the apparatus to perform: determining whether a synchronization signal has been received during a first set of synchronization resources; and when it is determined the synchronization signal was received, determining that the apparatus is allowed to use communication resources during a second set of synchronization resources for a first sidelink communication; and when it is determined the synchronization was not received, abstaining from using the communication resources during the second set of synchronization resources for a first sidelink communication; and monitoring the second set of synchronization resources for a synchronization signal.

Abstract: A method for a base station includes sending a request for a report on beamforming capability to a target user equipment; receiving the report on the beamforming capability from the target user equipment; allocating at least one positioning reference signal resource for use by the target user equipment based on at least the capability information included in the report; determining a beam sweeping mle based on the at least one positioning reference signal resource allocated for the target user equipment; and sending the positioning reference signal resource allocation and the beam sweeping mle to the target user equipment. A corresponding method for a user equipment includes receiving a request for a report on beamforming capability from a serving base station; sending the report on the beamforming capability to the serving base station; receiving information relating to at least one positioning reference signal resource and a beam sweeping rule from the serving base station; and performing beam sweeping on uplink positioning reference signal transmissions using the received positioning reference signal resource allocation based on the beam sweeping rule.

Abstract: The method implemented at a network device includes dividing a wireless system bandwidth into a plurality of non-overlapping bandwidth ranges each including a plurality of operating channels available for channel bonding. The method also includes allocating one of the plurality of bandwidth ranges for a wireless communication between the network device and a terminal device served by the network device. The method further includes determining, from the plurality of operating channels for the bandwidth range, one operating channel as a primary channel of the wireless communication. Embodiments of the present disclosure also provide a corresponding network device, a method implemented at a terminal device and a corresponding terminal device, and a non-transitory computer-readable medium.

Abstract: A device, method, apparatus and computer readable storage medium for RMA generation are disclosed. A first device performs timing synchronization with a second device (210). The first device generates, at a first time instance, a first random media access control address, RMA, in accordance with a rule configuration information, to communicate with the second device (220). Further, the first device generates, at a second time instance, a second RMA in accordance with the rule configuration information to communicate with the second device (230). The rule configuration information comprises time instructions comprising information corresponding to the first time instance, and information on a period of time starting from the first time instance and ending at the second time instance.

Abstract: Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable stor-age media for hybrid automatic repeat request acknowledgement (HARQ ACK) feedback for sidelink communications. In example embodiments, a first device determines a time window to be used by a second device to transmit HARQ ACK feedback for sidelink transmission from the first device to the second device. Then, the first device transmits an indication of the time window to the second device. Further, the first device monitors the HARQ ACK feedback from the second device within the time window.
