Abstract: The present invention relates to a beam-based multi-connection communication method, a terminal device, and a network device. The method may include the following: Based on a multi-beam connection established between a terminal and a base station, the terminal further selects a dedicated message beam from a common message range of the base station based on a measurement result of an uplink pilot, or the base station selects a dedicated message beam from a common message range of the base station based on a measurement result of a downlink pilot; and the terminal or the base station chooses to delete at least one established beam connection. By selecting and deleting a multi-beam connection between the terminal and the base station, a high-quality beam connection is maintained, and interruption of data transmission between the base station and terminal is avoided, thereby ensuring normal communication between the base station and the UE.

Abstract: Example data transmission methods and apparatuses are provided to reduce an uplink transmission latency of a user terminal and improve system resource utilization. One example method includes notifying, by a base station, a user terminal of a semi-persistent SPS period, where the SPS period is a short period. A first SPS resource is allocated, by the base station, to the user terminal. Data that is periodically sent by the user terminal based on the SPS period is received by using the first SPS resource.

Abstract: A method includes: allocating, by an eNB, a same uplink shared resource to m UEs, where m≥2; sending, by the UE to the eNB by using the uplink shared resource, uplink data that includes an identifier of the UE and/or buffer status information corresponding to the UE; generating according to successfully received uplink data, feedback information that includes the UE identifier and/or an uplink scheduling grant; and sending, by the eNB, the feedback information by using a MAC PDU, or sending acknowledgement information by using a downlink resource indicated by a combination of an agreed feedback location and an offset. A problem that an eNB cannot correctly send feedback information to each UE when the multiple UEs send uplink data by using a same uplink shared resource and DM-RS is resolved, so that each UE is clear about whether the uplink data of the UE is successfully sent.

Abstract: Embodiments of the present disclosure disclose a security configuration method for a radio bearer and a device. The method may include: obtaining, by a base station, a first security configuration message, where the first security configuration message is used to indicate whether security configuration needs to be performed on each of N radio bearers set up between the base station and a terminal device, and indicate security configuration parameters for M radio bearers on which security configuration needs to be performed, where N is a positive integer, M is an integer, and M≤N; and sending, by the base station, the first security configuration message to the terminal device. According to the embodiments of the present disclosure, applicability of security configuration can be improved.

Abstract: An uplink information sending methods and apparatus are provided. A communication device includes a processor coupled to a non-transitory memory, where the non-transitory memory stores an execution instruction to be executed in the processor. The execution instruction when executed enables the communication device to determine scheduling information and timing advance information. The scheduling information is used to instruct user equipment to send uplink information, and the timing advance information is used to adjust a timing advance used when the user equipment sends the uplink information. The execution instruction when executed further enables the communication device to adjust the timing advance according to the timing advance information, and send the uplink information according to the scheduling information by using an adjusted timing advance.

Abstract: A transmission method, a transmission apparatus, a network device, and user equipment are provided, and are applied to the field of communications technologies. The method includes: configuring, by a base station, a resource request parameter for first UE; allocating a first PUSCH resource used by the first UE to send resource request information; and allocating, to the first UE when the base station detects, on the first PUSCH resource, resource request information sent by the first UE, a second PUSCH resource used for sending data. In this way, PUCCH capacity limitation is effectively mitigated, and more UEs can send resource requests, so that resource usage in an uplink transmission process can be increased, and a system capacity can be increased.
