Abstract: Embodiments of this application provide a method for transmitting positioning assistance data and a device. The method includes: receiving, by a network device, at least one positioning assistance data message sent by a positioning server, where the at least one positioning assistance data message is used to carry positioning assistance data; and broadcasting, by the network device, a system message to a terminal device, where the system message is used by the terminal device to obtain the positioning assistance data. According to the embodiments of this application, the network device broadcasts the system message to broadcast the positioning assistance data. In this way, a problem of low efficiency of transmitting existing centralized positioning assistance data can be resolved, and a problem in the prior art that a positioning server needs to perform signaling communication with each terminal device in a unicast transmission scenario can be avoided, thereby reducing signaling overheads.

Abstract: This application relates to the field of wireless communication technologies, and in particular, to a time control, an apparatus, and a system. This application provides a timer control method, including: When downlink control information indicates data transmission of N hybrid automatic repeat request (HARQ) processes and a terminal device is configured with the N HARQ processes, where N is an integer greater than or equal to 2, a discontinuous reception inactivity timer is not started or the discontinuous reception inactivity timer is stopped. This application reduces time required by the terminal device to monitor a downlink channel or downlink data through control by the timer, thereby reducing power consumption of the terminal device.

Abstract: This application provides an information transmission method, a terminal device, and a network device. In technical solutions of this application, a target time interval in which a physical downlink control channel is not monitored or DCI is not sent is determined based on a value relationship between a quantity of TBs scheduled by the DCI and a first value, and a solution of sending and monitoring a physical downlink control channel in a scenario in which one piece of DCI schedules a plurality of TBs is specified, so that the physical downlink control channel can be effectively sent and monitored.

Abstract: A data transmission method and apparatus are provided. The method includes: sending, by a terminal device, a message 1 including a random access preamble to a first network device; receiving DCI and a message 2 including downlink data scheduled by the DCI from the first network device, wherein the DCI and/or the message 2 include/includes first information, which is used to schedule ACK/NACK feedback information of the message 2; and sending the ACK/NACK feedback information to the first network device based on the first information. According to the application, the first information is used to schedule the ACK/NACK feedback information, therefore the terminal device may send the ACK/NACK feedback information of the message 2 to the first network device in an MT-EDT scenario based on the first information, thereby improving robustness of transmission of the downlink data in the message 2.

Abstract: A message transmission method and device relating to the field of communications technologies are described that improve an anti-interference capability in message transmission. The method includes generating a scrambling code according to a scrambling code initialization seed, wherein the scrambling code initialization seed meets the following expression: cinit=R·2a7+P·(nf modk+1)·2b7 and then scrambling a message according to the scrambling code. The method further includes sending the scrambled message to a terminal on a physical downlink shared channel. Because the first time parameter has different values at at least two different moments, scrambling codes determined at the at least two corresponding different moments are different. Therefore, a possibility at which the base station uses a same scrambling code to scramble a same system message repeatedly in a time period is reduced, so that an anti-interference capability in system message transmission is improved.

Abstract: The present disclosure relates to data scheduling methods, apparatus, and systems. In one example method, a network device sends, to a terminal device, downlink control information (DCI) used to schedule N transport blocks (TBs). After determining that a downlink channel that carries first M TBs in the N TBs is transmitted in consecutive first downlink time units, the network device sends the downlink channel to the terminal device. The terminal device receives the downlink channel. After determining that ACKs/NACKs corresponding to the M TBs are transmitted in consecutive first uplink time units, the terminal device sends the ACKs/NACKs corresponding to the M TBs to the network device. N is a positive integer greater than 1, and M is a positive integer greater than 1 and less than or equal to N.
