Abstract: A Media Access Control (MAC) protocol data unit processing method includes: obtaining a MAC protocol data unit (PDU), wherein the MAC PDU includes N sub-PDUs, each sub-PDU includes a logical channel identifier (LCID), the N sub-PDUs are arranged in a first sequence, and N is a positive integer; parsing the N sub-PDUs according to the first sequence, and when a first sub-PDU is parsed, stopping the parsing and reserving a parsed second sub-PDU, wherein the second sub-PDU includes at least one sub-PDU before the first sub-PDU in the N sub-PDUs in the first sequence, and a value of an LCID included in the first sub-PDU is a specified reserved value. In this way, a manner for processing a MAC PDU can be provided when a value of an LCID is an invalid value or a reserved value.

Abstract: A method and a device for establishing an Evolved Packet System (EPS) bearer, where the method includes establishing, by a first base station to which a user equipment (UE) belongs, a first EPS bearer based on a first component carrier (CC) for the UE, wherein the first EPS bearer is an EPS bearer between the first base station and the UE; and instructing, by the first base station, a second base station to establish a second EPS bearer based on a second CC for the UE, wherein the second EPS bearer is an EPS bearer between the second base station and the UE. The present disclosure enables the UE to aggregate carriers of different frequency ranges from the first base station to which the UE belongs and the second base station to which the UE belongs to transmit data, thus improving the throughput of the data transmitted by the UE.

Abstract: This application provides a signal processing method and apparatus. A network device obtains capability information of a terminal device, where the capability information includes a processing time period for uplink data of the terminal device and a processing time period for uplink control information of the terminal device; determines a first time-frequency resource based on the capability information, where the first time-frequency resource is used to carry first uplink data and/or first uplink control information; and sends first signaling to the terminal device, where the first signaling indicates the first time-frequency resource. This application can improve efficiency of configuring a time-frequency resource by the network device for the first uplink data and/or the first uplink control information of the terminal device, thereby reducing a signal transmission delay.
