Abstract: The invention provides a mechanism for switching between a first and a second positioning procedure. The first positioning procedure may be an absolute positioning procedure and the second positioning may be a relative positioning procedure. The switch may be initiated by a network node (300) which can instruct a client device (100) to terminate the first positioning procedure and to activate the second positioning procedure or to instruct the client device (100) to continue with the first positioning procedure and to activate the second positioning procedure. Thereby, allowing the positioning procedure used by the client device (100) to be adapted e.g. based on dynamic requirements on positioning procedures set by applications.

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 feedback information sending method and an apparatus are provided. A first communications apparatus may determine sidelink feedback information, and send a reference signal to a second communications apparatus, where the reference signal carries the sidelink feedback information. In this way, terminals can send and receive the sidelink feedback information by using the reference signal, to improve transmission efficiency of the sidelink feedback information. When the terminal needs to send both a control channel or a data channel and feedback information in a same slot, this method avoids a problem that the terminal needs to simultaneously send two channels, e.g., the control channel (or the data channel) and a feedback channel, avoids reducing original transmission efficiency of the control channel or the data channel, and implements compatibility between sending through the control channel (or the data channel) and feedback through the feedback channel.

Abstract: A transmit end obtains a frequency hopping parameter and resource allocation information of a to-be-transmitted message, where the frequency hopping parameter includes at least one of bandwidth part indication information, beam indication information, reference signal configuration information, subcarrier spacing indication information, transmission waveform indication information, slot type indication information, channel type indication information, and transmission carrier indication information. The transmit end determines, based on the resource allocation information and the frequency hopping parameter, a physical resource used to send the to-be-transmitted message, where the physical resource includes information about a frequency domain resource on which the to-be-transmitted message is mapped in at least one time unit. The transmit end sends the to-be-transmitted message by using the physical resource.

Abstract: A feedback method and apparatus which are used to provide a feedback mechanism in a sidelink communications system, and may be applied to the internet of vehicles, for example, V2X, LTE-V, and V2V. The method includes: a first terminal device determines that a feedback condition is met, and sends feedback information to a second terminal device, where the feedback information includes at least one of channel state information and a receive response, and the receive response includes a positive acknowledgment, a negative acknowledgment, or discontinuous transmission. In this way, the feedback condition is set, so that the first terminal device sends the feedback information only when the feedback condition is met. In this way, resource overheads and information redundancy that are caused when each terminal device in a communication group sends feedback information are effectively avoided.
