Abstract: Methods and apparatus for sensor selection for localization and tracking are provided. A method (300) performed at an access point (101, 101a, 101b, 101c, 901, 902, 903) comprises: determining, a detectability of the access point (101, 101a, 101b, 101c, 901, 902, 903) for localization for a target device (102), based on channel state information of a radio link between the target device (102) and the access point (101, 101a, 101b, 101c, 901, 902, 903) (302); and determining whether the access point (101, 101a, 101b, 101c, 901, 902, 903) is to be used for position estimation of the target device (102) or not based on the detectability (304). A localization server (103) may further eliminate access points (101, 101a, 101b, 101c, 901, 902, 903) at poor positions from position estimation, by using a predefined weighted-kernel approach.

Abstract: Embodiments of the disclosure provide a method, device and computer readable medium for transmission scheme. According to embodiments of the present disclosure, the communication device may transmit an initial message to a further communication device via an antenna in an omnidirectional mode if the transmitting power can be achieved by the antenna in the omnidirectional mode. The communication device may transmit the initial message to the further communication device via the antenna in a directional mode if the transmitting power cannot be achieved by the antenna in the omnidirectional mode. In this way, latency for initializing the connection may be reduced and the successful connections are guaranteed at the same time.

Abstract: Embodiments of the present disclosure relate to a method and device for backhaul transmission. In example embodiments, the first network device transmits uplink (UL) data to a second network device in a first UL backhaul link, the first UL backhaul link being scheduled by the first network device. The second network device is located in upstream of the first network device. The first network device receives downlink (DL) data from the second network device in a first DL backhaul link. The first DL backhaul link is scheduled by the second network device. In this way, the transmission latency may be reduced, and the transmission efficiency may be improved.
