Abstract: The present invention relates to a scheduling request transmission method, so as to effectively transmit a scheduling request when scheduling request resources are configured on multiple carriers. The terminal receives a configuration parameter for a scheduling request from a base station; when the scheduling request is triggered, the terminal sends the scheduling request on a selected one carrier of multiple carriers according to the configuration parameter. Scheduling request resources are assigned to the terminal on multiple carriers by sending the configuration parameter, so that the terminal can send the scheduling request on the selected one carrier of the multiple carriers according to the configuration parameter. This provides a solution to effectively transmitting the scheduling request.

Abstract: A semi-persistent scheduling method includes: determining a semi-persistent scheduling (SPS) configuration parameter, where the SPS configuration parameter includes an SPS period length, symbol information, and an SPS activation command, where the SPS activation command is used to indicate a system frame number and a subframe number of a first time-frequency resource available for sending or receiving SPS data, and the symbol information is used to indicate a location of a symbol that is in a subframe and that is occupied by the first time-frequency resource; determining resource locations of time-frequency resources available for sending or receiving the SPS data based on the SPS period length, the symbol information, and the SPS activation command; and sending, by the network device, the SPS configuration parameter to a terminal device. Resource utilization of semi-persistent scheduling can be improved, and a transmission delay of the SPS data can be reduced.

Abstract: Embodiments of this application provide a method and an apparatus for setting a symbol in a communications system that uses a plurality of subcarrier spacings. The method includes: obtaining, by a terminal, a length of a reference blank symbol, where the length of the reference blank symbol is associated with a first subcarrier spacing, and the first subcarrier spacing is a minimum subcarrier spacing in the plurality of subcarrier spacings; and setting, by the terminal based on the length of the reference blank symbol and time domain information of the reference blank symbol, a blank symbol for a subcarrier corresponding to a second subcarrier spacing in the plurality of subcarrier spacings. According to the method and apparatus for setting a symbol provided in the embodiments of this application, when setting, based on the length of the reference symbol, a blank symbol in a subframe corresponding to a subcarrier used by the terminal, the terminal may set one or more complete symbols as blank symbols. This avoids a case in which a symbol cannot work normally because a part of the symbol is set as a blank symbol, thereby improving spectral efficiency of the system.

Abstract: Embodiments of the present disclosure provide a downlink synchronization method, an apparatus, and a system, and relate to the communications field, so as to reduce downlink synchronization complexity and improve downlink synchronization efficiency. According to the downlink synchronization method, abase station sends downlink synchronization reference information to UE by using dedicated signaling or a system message, where the downlink synchronization reference information is used to instruct the UE to perform downlink synchronization in a second cell by referring to a downlink synchronization channel of a first cell; and the base station sends, in the second cell according to location information of the UE, a beam including a downlink synchronization channel to the UE, where the first cell and the second cell include an overlapped coverage area. The embodiments of the present disclosure are applied to synchronization channel sending.

Abstract: The present disclosure relates to a reference signal transmission method. In one example method, physical layer signaling is received by a terminal device. The physical layer signaling includes configuration information. The configuration information indicates a time domain resource of a reference signal. The time domain resource of the reference signal is determined by the terminal device according to the configuration information. The reference signal and a first physical channel is sent by the terminal device. The reference signal is used for demodulation of the first physical channel.

Abstract: The method includes: obtaining, by UE, UE capability information of the UE; if the size of the UE capability information exceeds the maximum tolerance that can be processed by the PDCP layer of the UE, splitting the UE capability information into at least two pieces of part UE capability information, where each piece does not exceed the maximum tolerance that can be processed by the PDCP layer; and reporting at least one piece of part UE capability information to a network side device. According to this method, the UE capability information is split on a UE side, and reported to the network side device for a plurality of times.
