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: 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: 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.
