Abstract
Provided are a method for sending a signal channel, a base station, a storage medium, and an electronic apparatus. The method includes the following steps: a signal channel is configured, where the signal channel is used for cell search, synchronization and measurement; and the signal channel is sent to a terminal.
Claims18
A method for sending discovery reference signals (DRSs) in an unlicensed-carrier scenario, the method comprising:
- configuring, by a base station, a DRS, wherein the DRS comprises a synchronization signal/physical broadcast channel (SS/PBCH) block (SSB), a control resource set (CORESET) and a physical downlink shared channel (PDSCH), wherein the SSB, the CORESET and the PDSCH of the DRS are limited to use a same subcarrier spacing (SCS);
- determining, by the base station, a specified time window for sending the SSB;
- configuring, by the base station, at least one candidate SSB position for sending the SSB in a time unit of the specified time window, wherein a new candidate SSB position is configured in a time unit in which no candidate SSB position is defined in the specified time window;
- and
- sending, by the base station, the DRS to a terminal.

A base station, comprising:
- at least one processor configured, in an unlicensed-carrier scenario, to:
- configure a discovery reference signal (DRS), wherein the DRS comprises a synchronization signal/physical broadcast channel (SS/PBCH) block (SSB), a control resource set (CORESET) and a physical downlink shared channel (PDSCH), wherein the SSB, the CORESET and the PDSCH of the DRS are limited to use a same subcarrier spacing (SCS);
- determine a specified time window for sending the SSB;
- configure at least one candidate SSB position for sending the SSB in a time unit of the specified time window, wherein a new candidate SSB position is configured in a time unit in which no candidate SSB position is defined in the specified time window;
- and
- send the DRS to a terminal.

A method for receiving discovery reference signals (DRSs) in an unlicensed-carrier scenario, the method comprising:
- receiving, by a terminal from a base station, a DRS in a specified time window,
- wherein the DRS comprises a synchronization signal/physical broadcast channel (SS/PBCH) block (SSB), a control resource set (CORESET) and a physical downlink shared channel (PDSCH),
- wherein the SSB, the CORESET and the PDSCH of the DRS are received over a same subcarrier spacing (SCS),
- wherein at least one candidate SSB position is configured for receiving the SSB in a time unit of the specified time window, and
- wherein a new candidate SSB position is configured in a time unit in which no candidate SSB position is defined in the specified time window.
2 more elements
A terminal, comprising:
- at least one processor configured, in an unlicensed-carrier scenario, to:
- receive a discovery reference signal (DRS) from a base station in a specified time window,
- wherein the DRS comprises a synchronization signal/physical broadcast channel (SS/PBCH) block (SSB), a control resource set, CORESET, and a physical downlink shared channel (PDSCH),
- wherein the SSB, the CORESET and the PDSCH of the DRS are received over a same subcarrier spacing (SCS),
- wherein at least one candidate SSB position is configured for receiving the SSB in a time unit of the specified time window, and
- wherein a new candidate SSB position is configured in a time unit in which no candidate SSB position is defined in the specified time window.
