摘要： A method for adjusting Time Advance (TA) is disclosed, and is applicable to a system having multiple serving cells. The method includes: measuring arrival time of a downlink signal of a cell, and obtaining downlink delay information of the measured cell according to the arrival time of the downlink signal; and adjusting TA of uplink sent data according to the downlink delay information. Because the UE measures the downlink delay information, the signal detection performance is improved, and the interference to other surrounding UEs is reduced.

摘要： The present invention provides a method for sending and receiving control information, an apparatus and a communication system. The method for sending control information includes: setting respective control bits in a downlink control information (DCI) format to generate control information applied by a network side to a terminal, where the control bits include validity indication bits and transmission control bits, indication information indicating whether transmission control exercised by the network side on a transmission block is valid relative to the terminal is written into the validity indication bits, and the validity indication bits are located outside the transmission control bits; and sending the generated control information to the terminal. In the embodiments of the present invention, a network side device extends or changes functions of some control bits in the DCI format of the control information, so as to improve efficiency of using a resource overhead occupied by the control bits in the DCI format of the control information, and improve efficiency of using an overhead required for transmitting the control information.
