Abstract: A subframe processing method and device are disclosed. A terminal can determine a special subframe in a non-contiguous secondary carrier according to a maximum continuous channel occupancy duration and a channel listening duration of the non-contiguous secondary carrier, and a channel occupancy start reference time point and/or a channel listening start reference time point of the non-contiguous secondary carrier that are obtained, where the special subframe includes all or some gap symbols occupied by the channel listening duration, use all symbols except the gap symbols in the special subframe as symbols that can be occupied by a PDCCH and/or a PDSCH, and correspondingly receive or decode the PDCCH and/or the PDSCH in the special subframe according to the symbols that can be occupied by the PDCCH and/or the PDSCH.

Abstract: A power control method includes: obtaining, by a first terminal, power control information, where the power control information is information used to control a transmit power used by the first terminal when the first terminal communicates with a second terminal; determining a target transmit power based on the power control information; and sending first data to the second terminal based on the target transmit power. A first communication link is established between the first terminal and the second terminal. In the present disclosure, the following prior-art problem is resolved: In a relay or D2D communication scenario, a base station does not configure, for a specific terminal, a transmit power used by the terminal during D2D communication. Therefore, transmit powers used by different terminals during D2D communication are indicated to the different terminals, and a power control effect is improved.

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: Embodiments of the present disclosure disclose a mobility management method, user equipment, a storage node, and a base station. The mobility management method may include: determining, by user equipment (UE) in a connected state, a source identifier of the UE, where the source identifier is used to identify the UE; allowing the UE to enter a low consumption state after a low consumption activation condition is met, where in the low consumption state, the UE stores a connection context of the UE in the connected state and performs cell camping based on a cell reselection criterion in a moving process; and reporting, by the UE when a first preset condition is met, the source identifier to a second base station to which a second cell belongs, where the second cell is a serving cell on which the UE currently camps.

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.
