Abstract

The present application relates to the field of communications, and in particular to a channel and/or signal transceiving method and apparatus. The method comprises: a network side configuring a first channel and/or a first signal, wherein the first channel and/or the first signal are/is used for indicating the receiving and/or sending of a second signal of at least one terminal group corresponding to at least one terminal; and the network side sending the first channel and/or the first signal to the at least one terminal, and the terminal receiving, on the basis of a manner indicated by the network side, the second signal sent by the network side, such that when the terminal is in an RRC-idle or RRC-inactive state, the network side can reduce, in the manner, the number of times that various types of messages are received by a terminal side.

First claim

2. The method according to claim 1 , wherein the first channel is a power saving channel, and the first signal is a power saving signal; and/or
the second signal is at least one of the following signals: a paging signal, a synchronization signal block (SSB), a channel state indicator-reference signal (CSI-RS), a tracking reference signal (TRS), a phase tracking reference signal (PT-RS), a positioning reference signal (P-RS), or a sounding reference signal (SRS).

3. The method according to claim 1 , wherein the first channel and/or the first signal carry/carries first information, and the first information is used for indicating receiving and/or transmitting of the second signal of the at least one terminal and is used for implementing at least one of the following operations:
indicating receiving and/or transmitting of N quantity of second signals;
indicating receiving and/or transmitting of the second signal in M1 quantity of discontinuous reception (DRX) cycles;
indicating receiving and/or transmitting of the second signal in M2 quantity of second signal cycles;
indicating to skip receiving and/or transmitting of K quantity of second signals;
indicating to skip receiving and/or transmitting of the second signal in L1 quantity of DRX cycles;

indicating to skip receiving and/or transmitting of the second signal with a probability Q or (1-P).

4. The method according to claim 1 , wherein the transmitting, by the network side, the first channel and/or the first signal to the at least one terminal comprises:
transmitting, by the network side, in a condition that the network side determines that it needs to transmit the second signal, the first channel and/or the first signal to the at least one terminal.

5. The method according to claim 4 , wherein in a condition that the network side determines that it is no need to transmit the second signal, the network side does not transmit the first channel and/or the first signal to the at least one terminal.

6. The method according to claim 1 , wherein the kind of terminal group based on the bit of the first channel and/or the first signal comprises at least one kind of the following:
