Abstract: This application provides a measurement method and an apparatus. In the measurement method, a communications apparatus may receive configuration information, where the configuration information includes a cell list and indication information, and the indication information is used to indicate whether a measurement event is affected by the cell list; and the communications apparatus performs a measurement evaluation based on the cell list and the indication information. In this implementation, whether to perform a trigger evaluation for a measurement result of a cell in the cell list may be determined depending on whether the measurement event is affected by the cell list, to avoid an unnecessary trigger evaluation for a cell.

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 user equipment is configured to receive logged minimization of drive tests (MDT) configuration information and to determine, according to the received logged MDT configuration information, a Multimedia Broadcast Multicast Service (MBMS) set used for triggering logged MDT measurement and a measurement parameter used for performing the logged MDT measurement. The user equipment is also configured to perform the logged MDT measurement based on the measurement parameter when determining that an MBMS used for triggering the logged MDT measurement is being received, where the MBMS used for triggering the logged MDT measurement belongs to the MBMS set used for triggering the logged MDT measurement, thereby implementing the logged MDT measurement.

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 invention provide a random access method and an apparatus. PRACH configuration information of a base station is acquired, and a preamble is sent from a corresponding start PRACH resource, so that access of another terminal device is not affected when the base station identifies an access request of a terminal device that requires coverage enhancement. The solution includes: acquiring at least one group of physical random access channel PRACH configuration information that has been stored, where the at least one group of PRACH configuration information is carried in system information sent by the base station; parsing the at least one group of PRACH configuration information to obtain a corresponding start PRACH resource; and sending a preamble to the base station starting from the start PRACH resource, so that the base station establishes a connection to the terminal device according to the preamble.
