Abstract: A data transmission method includes determining, by a transmitting device, a long training sequence set, where the long training sequence set includes a plurality of long training sequences. The method also includes determining a mapping relationship between each long training sequence in the long training sequence set and first sub-identity information in identity information of each receiving device in a communications system. When data needs to be transmitted to a target receiving device, the method includes selecting a target long training sequence from the long training sequence set according to first sub-identity information of the target receiving device and the mapping relationship. The method includes performing encapsulation processing on the data according to the target long training sequence to generate a data packet, so as to carry the target long training sequence in the data packet. The method includes sending the data packet to the target receiving device.

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.

Abstract: Embodiments of the present invention disclose a network selection method, an apparatus and a base station. The method includes: determining each of networks satisfying requirements of a user when the user initiates a service or transmits a service; estimating an average energy efficiency of a system during service transmission after the user selects to access each of the networks; selecting a network which can make the average energy efficiency of the system reach a preset threshold value to serve the user. Embodiments of the present invention solve a problem in the prior art that, because no consideration is given to network energy consumption in the network selection, system energy efficiency is reduced. Through comprehensive consideration of network energy efficiency and system energy efficiency, the need for energy saving and consumption reduction is met.

Abstract: Embodiments of this application provide an uplink transmission control method and an apparatus. A micro base station sends an uplink resource configuration request to a macro base station, the macro base station sends, to the micro base station, an uplink resource configuration indication that is used to allocate an uplink resource to the micro base station, and then the micro base station instructs user equipment to transmit uplink information by using the uplink resource. It can be seen that, after the macro base station allocates the uplink resource to the micro base station, the micro base station may use the uplink resource to receive the uplink information transmitted by the user equipment.
