Abstract

A communications method includes: when a terminal device is in a non-connected state, a system information block is received from a network device, where the system information block includes first information; and configuration of a reference signal used for operations such as automatic gain control (AGC) adjustment and time and frequency synchronization can be known based on the first information. In this way, the terminal device can wake up at a location of a first reference signal to prevent terminal device from waking up too early at a location of a synchronization signal block and to effectively reduce power consumption of the terminal device.

Dependent claims

A communications method implemented by a first wireless communications apparatus, wherein the communications method comprises:

receiving a system information block when the first wireless communications apparatus is in a non-connected state, wherein the system information block comprises first information, and wherein the first information comprises first configuration information of a first reference signal that is used when the first wireless communications apparatus is in the non-connected state;
and
receiving, from a network device based on the first information, the first reference signal.

A communications method comprising:

when a second wireless communications apparatus is in a connected state:
sending, by a network device, third information, wherein the third information comprises configuration information of a second reference signal for use when the second wireless communications apparatus is in the connected state;
and
receiving by the second wireless communications apparatus, the third information;
when a first wireless communications apparatus is in a non-connected state;
sending by the network device, a system information block;
receiving, by the first wireless communications apparatus, the system information block, wherein the system information block comprises first information, wherein the first information comprises configuration information of a first reference signal for use when the first wireless communications apparatus is in the non-connected state, and wherein the second reference signal is a subset of the first reference signal;
parsing, by the first wireless communications apparatus, the first information to obtain a receiving parameter;
sending by the network device, second information;
receiving, by the first wireless communications apparatus, the second information;
indicating a status of the first reference signal;
determining, by the first wireless communications apparatus, that the status meets a condition,
receiving in response to determining that the status meets the condition, from the network device, and based on the receiving parameter, the first reference signal before a paging occasion (PO);
determining, by the first wireless communications apparatus, that the status does not meet the condition;
receiving, in response to determining that the status does not meet the condition, a synchronization signal block (SSB);
performing, by the first wireless communications apparatus using the first reference signal or the SSB, at least one of automatic gain control (AGC) adjustment, time synchronization, or frequency synchronization;
sending, by the network device, paging;
and
receiving, by the first wireless communications apparatus, the paging in the PO.
