Abstract

The invention discloses a method for sending a control signal, which is used to solve the technical problem of large system overhead caused by the central node continuously sending the control signal to the remote node. The method includes: after the central node establishes a connection with the remote node, the central node receives notification signaling sent by the remote node, the notification signaling is used to indicate whether the central node sends a control signal; if The notification signaling instructs the central node to send the control signal, and the central node sends the control signal to the remote node after receiving the trigger signaling of the remote node according to the indication of the notification signaling. the control signal. The invention also discloses a corresponding receiving method and equipment.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a method and equipment for sending and receiving control signals. Background technique [0002] For wireless communication systems, such as LTE (Long Term Evolution) systems, in the initial access phase, the terminal detects PSS (Physical Synchronization Signal, primary synchronization signal) / SSS transmitted by eNB (Evolved Node B, evolved node B) (Secondary Synchronization Signal) Obtain cell ID (Identity), initial timing information and initial frequency offset information, etc., and obtain others by demodulating the PBCH (Physical Broadcast Channel) transmitted by eNB System information, the terminal establishes a connection with the eNB through the acquired control signals. [0003] After the terminal establishes a connection with the eNB, no matter whether the terminal still needs control signals such as PSS / SSS and PBCH, the eNB will continue to send these informa...
