Abstract: This application discloses a communication method and apparatus that activate a secondary cell. If the activated cell is an unknown secondary cell, in response to a terminal device detecting the secondary cell, the terminal device may send indication information to a network device. The indication information is used to trigger the network device to send an RS. In this way, in response to receiving the indication information, the network device may send the RS to the terminal device. Therefore, the terminal device avoids waiting a long period of time for the network device to send a reference signal, which can reduce a delay for activating the secondary cell.

Abstract: This application relates to the field of communication technologies and discloses a communication method and a communication apparatus, which are used to resolve a problem of a large activation delay of a secondary serving cell serving a terminal device in an existing technology. The method includes: A network device sends temporary SSB burst configuration information to a terminal device served by a secondary serving cell, where the temporary SSB burst configuration information includes a periodicity and/or an offset for sending a temporary SSB burst by the network device in the secondary serving cell configured for the terminal device. The network device sends a temporary SSB burst in the secondary serving cell based on the temporary SSB burst configuration information, where a temporary SSB included in the temporary SSB burst does not include a PBCH.

Abstract: A method and device for estimating the time of arrival (ToA) of a radio signal are proposed. The radio signal comprises M subsignals carried on M subcarriers, where M is an integer ≥2. The number of propagation paths and the time of arrival associated with a first path are estimated. The technique can improve ToA estimation accuracy, especially in a multipath fading channel, and reduce the need for channel information.

Abstract: Embodiments of the present invention provide a terminal device and a positioning system, and relate to the field of communications technologies. The terminal device is configured to: obtain identifiers of at least two antenna elements and attribute information of a reference signal corresponding to each of the at least two antenna elements; receive at least two reference signals based on the attribute information, where the at least two reference signals are sent by corresponding antenna elements of the at least two antenna elements, respectively; obtain positioning information; and send, to the network device, the positioning information and identification information of antenna elements corresponding to the positioning information. Positioning signals obtained by different antenna elements are different, so that the terminal device can identify which antenna element a received positioning signal comes from. Therefore, an improved distributed antenna system can implement terminal device positioning, and improve indoor positioning accuracy.

Abstract: The present invention provides a signal determining method and an apparatus, so as to resolve a problem, in a conventional positioning method, that a signal receiving device cannot accurately determine whether a received signal is an aggregated reference signal, and consequently, positioning fails due to a relatively large error of location information obtained by means of positioning. The method is as follows: A signal receiving device may estimate, according to a TAE between at least two subcarriers used by a signal sending device to transmit a reference signal and a reference signal sent by the signal sending device on each subcarrier, an aggregated reference signal that is sent by the signal sending device and that is obtained after carrier aggregation. After receiving a signal, the signal receiving device determines whether the signal is an aggregated reference signal sent by the signal sending device.

Abstract: A positioning signal processing method includes receiving positioning reference signal (PRS) configuration information from a positioning device. A PRS is received as a PRS resource set. Each PRS resource set includes one or more PRSs. One access network device corresponds to one or more PRS resource sets. The positioning signal processing method further includes determining PRS time domain information based on the PRS configuration information. The time domain information includes a periodicity (P) of the PRS and a symbol length of the PRS in the P. The positioning signal processing method further includes receiving a plurality of PRSs based on the PRS time domain information.
