Abstract: There is provided a method and apparatus for tracking a device. The tracked device may be a wearable device worn by a user participating in an athletic activity. An anchor device is positioned with respect to a playing area and receives signals from the tracked device. The anchor device estimates the position of the tracked device by measuring a distance and direction of the signal, and decodes the signal to obtain measurements taken by the tracked device. The position and the measurements are combined to produce tracking data for the device.

Abstract: Embodiments of this application provide a synchronization signal block transmission method and a communications apparatus. The method includes: A network device sends an SSB to a terminal device in a resource position of the SSB. Correspondingly, the terminal device receives the SSB. In this process, a symbol included in the resource position of the SSB does not overlap with an uplink symbol in a plurality of self-contained slot structures as much as possible. This method can reduce a probability that the symbol included in the resource position of the SSB conflicts with an uplink symbol in as many self-contained slot structures as possible, to avoid cross interference, and therefore can support reliable transmission in as many self-contained slot structures as possible.

Abstract: Embodiments of this application disclose a message transmission method and apparatus, a terminal, and a base station. In the method, a symbol or symbol group may be used as a granularity to select a plurality of symbols or symbol groups from one or more slots and then allocate the plurality of symbols or symbol groups to a same terminal for transmitting data. The plurality of symbols or symbol groups may be used for uplink data scheduling or may be used for downlink data scheduling. Therefore, a slot resource is allocated at a small granularity, so that a time domain resource is more flexibly allocated, and the slot resource is more fully utilized. This helps improve message transmission efficiency, thereby expanding a coverage area.

Abstract: A method and an apparatus for determining an RBG size are provided. In the method, a network device or a terminal determines an RBG size set, where the RBG size set may include one or more possible RBG sizes; and determines a first RBG size included in the RBG size set. The network device allocates a resource to the terminal by using the determined first RBG size. The terminal determines, based on the determined first RBG size, the resource allocated by the network device to the terminal.
