Abstract: Disclosed are devices for time synchronization offset identification and refinement for network based positioning in an unlicensed spectrum. An example network 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 network device to receive listen-before-talk (LBT) outcomes from a plurality of base stations (BSs), and identify whether one or more of the plurality of BSs have a time synchronization offset based on the LBT outcomes. The LBT may be related to a reference signal (RS) configured on the BSs. The related methods, apparatuses and computer program product are also disclosed.

Abstract: Embodiments of the present disclosure relate to mechanism for transmission for wideband system in unlicensed spectrum. According to embodiments of the present application, a transmission coordination mechanism is proposed to facilitate transmission in a wideband system. The network device may puncture on-going transmission on neighbor bands to ensure no power leakage to the band with later transmission. In this way, it can minimize the in-device power leakage issue when the network device performs LBT for later transmission.

Abstract: Examples of the disclosure relate to communication methods and apparatuses, an access point, stations and a computer readable medium. An embodiment of the method comprises: determining, at an access point and based on determining that a direct link between stations based sensing procedure is triggered, a first station and a second station associated with the sensing procedure; and transmitting, to at least one of the first station and the second station, a sensing performing request for performing the sensing procedure. In this way, target sensing between non-access-point stations is achieved, such that sensing coverage is extended and a sensing effect is improved.

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of PRS design for low power tracking The method comprises receiving from a second device an indication that a Sounding Reference Signal, SRS, is to be used for a positioning process of the first device unless a further indication is received; and transmitting a SRS to a third device and a fourth device, the third device being responsible for measuring a position of the first device in the positioning process. In this way, a SRS can be applied for multiple cells and the handover can be avoided or SRS resources re-configuration can be avoided even if the handover occurs at the UE. The power consumption and the positioning latency of the UE can be reduced. Meanwhile, the signalling overhead to setup RRC connection may also be reduced.
