Abstract: Embodiments of the present disclosure disclose a data transmission method and apparatus. The data transmission method includes: performing, by a Packet Data Convergence Protocol (PDCP) entity, lossless transmission on PDCP protocol data units (PDUs) or PDCP service data units (SDUs), where each of the PDCP PDUs or the SDUs is associated with one serial number. In this embodiment, during lossless transmission, no data packet is lost, thereby ensuring communication quality in an inter-station carrier aggregation scenario and achieving an optimization objective.

Abstract: Embodiments of the present invention provide a variable bandwidth-based communication method and an apparatus. The method includes: sending, by a network node, indication information to UE, where the indication information is used to indicate a target bandwidth parameter used by a serving cell corresponding to the UE; and communicating, by the network node, with the UE based on the target bandwidth parameter, where the target bandwidth parameter includes at least one of a target bandwidth, a target center frequency, and an enablement time of the target bandwidth. In this way, the network node can communicate with the UE in a changed bandwidth, so as to avoid a case in which communication is still performed in a relatively high bandwidth when a network load is relatively low, and reduce device power consumption.

Abstract: The method may include: after receiving, through a first interface or a second interface, resource allocation information of a neighboring cell of a serving cell in which UE is located, a network device may allocate a resource to the UE based on the resource allocation information of the neighboring cell, so as to prevent the UE from using a same resource as UE located in the neighboring cell, and reduce interference to the neighboring cell; or allocate, to the UE, a resource with relatively small interference to the UE, so as to reduce interference of the neighboring cell to the UE. The first interface is an interface that performs communication by using a UE-to-UE communications technology. The second interface is an interface that performs communication by using a UE-to-network device communications technology.

Abstract: The present disclosure relates to apparatus, methods, and systems for cell selection. One example method includes measuring a received signal communication parameter value of a first cell, determining whether the communication parameter value is greater than a first threshold, if the communication parameter value is less than or equal to the first threshold, obtaining a second threshold, determining whether the communication parameter value is greater than the second threshold, and if the communication parameter value is greater than the second threshold, setting the first cell as a serving cell of a terminal device.

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.
