Title:
POLLING DEVICE FOR MULTICAST BROADCAST SERVICE INTEREST INDICATION
Document Type and Number:
WIPO Patent Application WO/2022/236705
Kind Code:
A1
Abstract:
Example embodiments of the present disclosure relate to polling a device for multicast broadcast service interest indication. A first device receives, from a second device, a physical downlink control channel (PDCCH) order addressed by a paging radio network temporary identifier for the first device. The PDCCH order comprises a request for an indication that at least one multicast broadcast service is to be received by the first device. The first device transmits, to the second device, a random access preamble associated with the at least one multicast broadcast service as a response to the request. Through this solution, the first device that monitors the single PDCCH order may have less power consumption.
