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: A method and apparatus for timing advance (TA) synchronization for uplink (UL) data transmissions are provided. A base station transmits a TA instruction to a UE. The TA instruction indicates one of at least two TA options. The first TA option indicates direct initial grant-free (GF) uplink (UL) data transmissions. The second TA option indicates indirect initial GF UL data transmissions with the UE initiating TA reference signaling for updating a TA parameter of the UE. The UE performs an initial GF UL data transmission to the base station based on the TA instruction.
