Abstract: An adjustment method includes receiving, by a terminal, a redistribution command sent by a network device, where the redistribution command is used to adjust a frequency priority or a cell priority of a terminal in a cell; and ignoring, by the terminal, the redistribution command based on a status of the terminal. Network signaling overheads can be reduced in a process in which a network side instructs to perform redistribution.

Abstract: The present invention provides an uplink reference signal sending method, and the method includes: sending, by a terminal device, an uplink reference signal on N1 second component carriers within a determined uplink reference signal sending time, and prohibiting, on M1 first component carriers in M first component carriers within the sending time, the terminal device from sending an uplink signal, where the first component carriers are carriers on which scheduling of uplink data transmission is allowed, and the second component carriers are carriers on which scheduling of uplink data transmission is prohibited. N1≤M1, in other words, within the sending time, a quantity N1 of second component carriers on which the uplink reference signal is sent is less than or equal to a quantity M1 of first component carriers on which sending of the uplink signal is prohibited.

Abstract: This application provides a communication method, an apparatus, and a communications system, and relates to the field of communications technologies. A terminal device receives system information broadcast by a network device, and determines a bandwidth of an initial BWP based on the system information. The system information includes first indication information. The first indication information indicates that the bandwidth of the initial BWP used for the terminal device is a first bandwidth or a second bandwidth. The first bandwidth is indicated by using a first bandwidth parameter carried in the system information. The second bandwidth is a bandwidth of a CORESET 0. The CORESET 0 is used to schedule the system information.

Abstract: A data processing method by a data sending apparatus is described. The method includes receiving a data packet from a PDCP layer, where the data packet is used as an RLC SDU. The method further includes encapsulating the RLC SDU into at least one RLC PDU, where each one of the at least one RLC PDU includes a header and a payload. The payload carries data from a single RLC SDU. It can be learned that a transmit end no longer performs concatenation processing at the RLC layer on the data packet. In this way, concatenation processing at the transmit end is reduced, and processing complexity and processing latency are further reduced. In addition, processing at a receive end also becomes simpler and more efficient.
