RECEIVING PHYSICAL DOWNLINK CONTROL CHANNELS FOR MULTICAST AND BROADCAST SERVICES AT MONITORING OCCASIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17443884 titled 'RECEIVING PHYSICAL DOWNLINK CONTROL CHANNELS FOR MULTICAST AND BROADCAST SERVICES AT MONITORING OCCASIONS

Simplified Explanation

The abstract of this patent application describes a wireless communication system where a user equipment (UE) receives an indication from a base station about the type of physical downlink control channel (PDCCH) associated with a common search space (CSS). The first type of PDCCH corresponds to a cell-broadcast PDCCH, while the second type corresponds to a UE-specific PDCCH. The CSS is used for downlink control information (DCI) with a cyclic redundancy check scrambled by a group radio network temporary identifier (G-RNTI) that schedules a multicast and broadcast service (MBS). The UE can receive either the first or second type of PDCCH from the base station.

• The patent application is related to wireless communication systems.
• It focuses on the indication of the type of PDCCH associated with a common search space (CSS).
• The first type of PDCCH corresponds to a cell-broadcast PDCCH.
• The second type of PDCCH corresponds to a UE-specific PDCCH.
• The CSS is used for downlink control information (DCI) with a cyclic redundancy check scrambled by a group radio network temporary identifier (G-RNTI).
• The G-RNTI schedules a multicast and broadcast service (MBS).
• The user equipment (UE) can receive either the first or second type of PDCCH from the base station.

Potential Applications

This technology can be applied in various wireless communication systems, including cellular networks and other wireless networks.

Problems Solved

This technology solves the problem of efficiently indicating the type of physical downlink control channel (PDCCH) associated with a common search space (CSS) in a wireless communication system.

Benefits

The benefits of this technology include:

• Improved efficiency in indicating the type of PDCCH associated with a CSS.
• Enhanced performance in downlink control information (DCI) transmission.
• Better management of multicast and broadcast services (MBS) scheduling.

Original Abstract Submitted

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication that indicates whether a common search space (CSS) is associated with a first type of physical downlink control channel (PDCCH) or a second type of PDCCH. The first type of PDCCH may correspond to a cell-broadcast PDCCH and the second type of PDCCH may correspond to a UE-specific PDCCH. The CSS may be for downlink control information (DCI) with a cyclic redundancy check scrambled by a group radio network temporary identifier (G-RNTI) that schedules a multicast and broadcast service (MBS). The UE may receive, from the base station, the first type of PDCCH or the second type of PDCCH. Numerous other aspects are described.
