Method for distributing and obtaining CORESET in idle state, base station, user equipment, and readable medium

Abstract

The invention discloses a method for distributing and obtaining a CORESET in an idle state, a base station, user equipment, and a readable medium. The method comprises the steps: configuring time andposition information of the CORESET in the idle state, wherein the time and position information includes a number of symbols occupied by the CORESET in the idle state, or a number of symbols occupiedby the CORESET in the idle state and a start position of the CORESET in the idle state, and the symbol is a symbol in a parameter set used by the CORESET; configuring the location information of theidle state CORESET in the idle state in the system frame number; transmitting the configuration information to the UE, so that the UE can select the start position of the CORESET in the idle state inthe current configuration based on the received configuration information according to a preset relation table between the number of symbols occupied by the CORESET in the idle state and the start position of the CORESET in the idle state. According to the above scheme, the method does not need to directly indicate the CORESET in the idle state, so the bandwidth overhead of signaling indicating the CORESET in the idle state can be effectively reduced.

Description

Technical field [0001] The embodiments of the present invention relate to the field of communications, and in particular to a method for allocating and acquiring an idle CORESET, a base station, a user equipment, and a readable medium. Background technique [0002] In the 5G system, the user equipment (UE) in the idle state needs to monitor the Physical Downlink Control Channel (PDCCH), blindly check its public search space, and obtain the Downlink Control Information (DCI). ) In order to receive common control messages, such as Remaining Minimum System Information (RMSI), paging messages, etc., in the indicated Physical Downlink Shared Channel (PDSCH). The time-frequency resource corresponding to the idle PDCCH is called a control resource set (CORESET). [0003] The base station sends the Master Information Block (MIB) in the Physical Broadcast Channel (PBCH) to indicate the first CORESET that the UE needs to monitor in the idle state, so that the UE can blindly detect the first...

Problems solved by technology

For the signaling indicating the CORESET in the idle state, the direct indication method is currently used. When the signaling indicating the CORESET in the idle state is large, the bandwidth overhead of the network will be very large.
