Abstract: Embodiments of the present disclosure relate to communication in sidelink positioning. According to one aspect of the present disclosure, a second device generates a second PRS for positioning of a first device by using a set of second devices including the second device and transmits the second PRS to the first device. The first device communicates with the set of second devices via a sidelink interface. The second PRS is at least transmitted over a bandwidth occupied by a second set of sidelink data channels from the set of second devices to the first device in a time slot. In this way, an improved transmission of PRS from a supporting device is achieved, and efficient and low latency sidelink based ranging/positioning is allowed.

Abstract: Embodiments of the present disclosure relate to UL-based and DL-based positioning in a wireless communication network. A method comprises: determining, by a first device, an estimation of a propagation delay for a first reference signal to be transmitted from a second device; in accordance with a determination that the estimation of the propagation delay exceeds a threshold delay, determining a target period within a symbol on which at least a part of the first reference signal is transmitted; and performing positioning measurements on the first reference signal within the target period. As such, the receiver is capable of applying an adaptive and adjustable window for receiving different positioning reference signals (PRSs) depending on various conditions and situations. In this way, the PRS measurement performance and the positioning accuracy can be greatly improved.

Abstract: Example embodiments relate to sidelink communication with reduced power consumption. In an embodiment, a terminal device may comprise at least one processor and at least one memory including computer program code. The at least one memory and the computer program code may be configured to, with the at least one processor, cause the terminal device to monitor sidelink transmission during a monitoring time-interval of a transmission period, and ignore a re-transmission time-interval subsequent to the monitoring time-interval in the transmission period in a case where no sidelink transmission to the terminal device is received in the monitoring time-interval.

Abstract: Example embodiments of the present disclosure relate to handover of subnetworks. The first apparatus determines that a first subnetwork is triggered to handover from a first cell to a second cell, the first apparatus being in the first subnetwork; based on the triggering, communicates with at least one other apparatus in the first subnetwork by using a first frequency resource; receives, from a second apparatus providing the second cell, resource configuration indicating a second frequency resource to be used in the first subnetwork instead of the first frequency resource; and communicates with the at least one other apparatus by using the second frequency resource indicated in the resource configuration.

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.

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of retransmission of sidelink positioning reference signal (PRS). The method comprises transmitting, to a second device, a first sidelink reference signal associated with a positioning or ranging procedure of the first device; and receiving, from the second device, a second sidelink reference signal associated with the positioning or ranging procedure, the second sidelink reference signal comprising information indicating whether the first sidelink reference signal needs to be retransmitted. In this way, the retransmission of the sidelink PRS can be triggered without extra resource consumption and a fast RTT estimation for sidelink ranging and positioning can be achieved.

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of HARQ for NR sidelink communication in unlicensed spectrum. The method comprises receiving, from a second device, an indication of at least two candidate sets of code domain resources for the first device to transmit a feedback message for a sidelink transmission between the first device and a third device; and transmitting, to the third device, the feedback message on a target set of code domain resources determined from the at least two candidate sets of code domain resources based on a listen before talk procedure. In this way, additional code domain resources may provide more available time occasions as backup resources for HARQ feedback of sidelink transmission in unlicensed band, which may increase reliability of HARQ feedback transmission for sidelink communication in unlicensed spectrum. Hence it can eventually increase spectral efficiency by avoiding unnecessary retransmission of PSCCH/PSSCH, and can also reduce transmission latency in the meantime.
