Embodiment 1

[0142] In Embodiment 1, it is assumed that the network side device configures the MTCH scheduling window for the terminal. The MTCHscheduling window contains L slots. In this embodiment, it is assumed that L is 8. Assume that the network side device configures two search spaces for the terminal to transmit the PDSCH of the scheduled MTCH, where the transmission period of SS#1 is 1 slot, the transmission period of SS#2 is 2 slots, and the transmission period of SS#1 is 2 slots. The PDCCH is scrambled by G-RNTI#1, and the PDCCH transmitted in SS#2 is scrambled by G-RNTI#2.

[0143] Assuming that the number of optional SSBs actually transmitted by the terminal is 4, in this embodiment, the network side device may configure the number of SSBs through the ssb-PositionsInBurst information element carried in SIB1.

Embodiment 2

[0155] In Embodiment 2, it is assumed that the network side device configures the MTCH scheduling window for the terminal. The MTCHscheduling window contains L slots. In this embodiment, it is assumed that L is 16. It is assumed that the network side device configures two search spaces for the terminal to transmit the PDSCH of the scheduled MTCH, in which the transmission period of SS#1 is 2 slots, the transmission period of SS#2 is 2 slots, and the transmission period of SS#1 is 2 slots. The PDCCH is scrambled by G-RNTI#1, and the PDCCH transmitted in SS#2 is scrambled by G-RNTI#2. The MOs of SS#1 and SS#2 satisfy time-division multiplexing in the time domain, that is, the MOs do not overlap at all in the time domain.

[0156] Assuming that the number of optional SSBs actually transmitted by the terminal is 4, in this embodiment, the network side device may configure the number of SSBs through the ssb-PositionsInBurst information element carried in SIB1.

Embodiment 3

[0165] In Embodiment 3, it is assumed that the network side device configures the MTCH scheduling window for the terminal. The MTCHscheduling window contains L slots. In this embodiment, it is assumed that L is 8. Assume that the network side device configures two search spaces for the terminal to transmit the PDSCH of the scheduled MTCH, where the transmission period of SS#1 is 1 slot, the transmission period of SS#2 is 2 slots, and the transmission period of SS#1 is 2 slots. The PDCCH is scrambled by G-RNTI#1, and the PDCCH transmitted in SS#2 is scrambled by G-RNTI#2. The MOs of SS#1 and SS#2 completely overlap in the time domain.

[0166] Assuming that the number of optional SSBs actually transmitted by the terminal is 4, in this embodiment, the network side device may configure the number of SSBs through the ssb-PositionsInBurst information element carried in SIB1.

Abstract

The invention provides a mapping relation determination method and device, and a storage medium, and the method comprises the steps: determining the binding of a scheduling window and a plurality of group radio network temporary identifiers (G-RNTIs); based on a predefined priority sequence, determining a mapping relationship between a monitoring opportunity MO of each search space in the scheduling window and a synchronization signal block SSB; wherein the MO is used for monitoring the time domain position of a physical downlink control channel (PDCCH). According to the method and the device, when one scheduling window is bound with a plurality of G-RNTIs, the network side equipment and the terminal can accurately determine the mapping relation between the MO and the SSB of each search space, so that the terminals at different geographic positions in the cell can receive the PDCCH transmitted in the search space, and the normal operation and high availability of the terminal service are ensured.

Description

technical field [0001] The present disclosure relates to the field of communications, and in particular, to a method and device for determining a mapping relationship, and a storage medium. Background technique [0002] Rel-17 (Release-17, version 17) MBS (Multicast Broadcast service, multicast broadcast service) supports IDLE (idle state) / INACTIVE (inactive state) terminals to receive MBS services. Considering that the terminal in IDLE state / INACTIVE state does not feed back beam information to the network side device, it is necessary to send data in different beam directions to ensure that terminals in different physical locations in the cell can receive the MBS service. [0003] However, when multiple G-RNTIs (Group-Radio Network Temporary Identity, group wireless network temporary identity) are bound to one MTCH (Multicast Traffic Channel, multicast transmission channel) scheduling window (scheduling window), how to determine the MO of the PDCCH There is currently no cl...
