Abstract: Methods, apparatus, and systems for data or information transmission are provided. In one aspect, a data sending method by a terminal device includes: determining indication information, determining, based on the indication information, a transport block size (TBS) used to send data, and sending the data based on the determined TBS. The terminal device can determine at least two of first information indicating that the TBS is a first TBS, second information indicating that the TBS is a second TBS, or third information indicating the terminal device to select a TBS from a TBS set as a third TBS used by the terminal device to send data. The TBS set is determined based on the first TBS, and can include at least one of the second TBS or the third TBS. The indication information includes one of the at least two of the first, second, or third information.

Abstract: An access control method and an apparatus, such that a network device sends an access control configuration information to a terminal device, where the access control configuration information is used to indicate access control mode information corresponding to at least one coverage area; and the terminal device determines the access control mode of the terminal device based on the access control configuration information and a coverage area of the terminal device. As a result, terminal devices in a network may be prevented from impacting on the network when the terminal devices simultaneously access the network, to reduce network congestion.

Abstract: A data transmission method and a device are provided, so as to resolve problems of low resource utilization and inability to meet a requirement on a data transmission delay. The method includes: sending, by a terminal device, a random access request message to a network device by using a first random access resource; sending, by the network device to the terminal device, a random access response message that includes first information, where the first information is used to indicate a transmission resource allocated by the network device to the terminal device; and sending, by the terminal device based on a result of comparing a size of the transmission resource with a size of an RRC message and/or a result of comparing the size of the transmission resource with a size of second data, first data to the network device by using a specified message.

Abstract: A method includes: sending, by a first network device, a first configuration message to a terminal device, where the first configuration message is used to instruct the terminal device to configure a second ciphering/deciphering function associated with a second network device and share a first data packet numbering/reordering function, and the terminal device is configured with the first data packet numbering/reordering function and a first ciphering/deciphering function associated with the first network device; and receiving, by the first network device, a first configuration complete message sent by the terminal device. In this embodiment, the first configuration message is used so that the terminal device may configure the function associated with the second network device. Therefore, during handover, the terminal device may simultaneously perform data transmission with the second network device and the first network device, to reduce or avoid a service interruption time caused by handover.

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 present disclosure is directed to a D2D data transfer method, and user equipment and a network device that use the method. In one method, user equipment determines a logical channel used for to-be-transmitted Device to Device (D2D) data. The user equipment determines a logical channel group corresponding to the logical channel. The user equipment reports, to a network device, a D2D data volume of the logical channel group for the user equipment. The user equipment sends, on a D2D resource that is allocated by the network device to the user equipment according to the D2D data volume, the to-be-transmitted D2D data to another user equipment by using the determined logical channel.
