Abstract
Disclosed is a method of receiving a physical downlink control channel (PDCCH) through a search space (SS) set by a user equipment (UE) in a wireless communication system. The method includes transmitting first information related to the number of X slots and second information related to the number of at least one Y slot, and receiving a PDCCH through a UE-specific SS (USS) set within the at least one Y slot, based on the first information and the second information. The at least one Y slot is included in the X slots, and X and Y are positive integers.
Claims14
A method of monitoring physical downlink control channel (PDCCH) by a user equipment (UE) in a wireless communication system, the method comprising:
- indicating a capability to monitoring PDCCH according to combination (X, Y),
- wherein X and Y are numbers of consecutive slots;
- monitoring PDCCH for a UE-specific Search Space (USS) set in any slot of the Y slots, and
- wherein the Y slots are within the X slots and the X and the Y are positive integer, and
- wherein a monitoring periodicity of the USS set is an integer multiple of a length of the X slots.
A user equipment (UE) of monitoring physical downlink control channel (PDCCH) in a wireless communication system, the UE comprising:
- at least one transceiver;
- at least one processor;
- and
- at least one memory operably connected to the at least one processor and configured to store instructions causing, when executed, the at least one processor to perform operations comprising:
- indicating, through the at least one transceiver, a capability to monitoring PDCCH according to combination (X, Y),
- wherein X and Y are numbers of consecutive slots;
- monitoring PDCCH for a UE-specific Search Space (USS) set in any slot of the Y slots, and
- wherein the Y slots are within the X slots and the X and the Y are positive integer, and
- wherein a monitoring periodicity of the USS set is an integer multiple of a length of the X slots.
A method of transmitting physical downlink control channel (PDCCH) by a base station (BS) in a wireless communication system, the method comprising:
- receiving a capability to monitoring PDCCH according to combination (X, Y),
- wherein X and Y are numbers of consecutive slots;
- transmitting PDCCH for a UE-specific Search Space (USS) set in any slot of the Y slots, and
- wherein the Y slots are within the X slots and the X and the Y are positive integer, and
- wherein a monitoring periodicity of the USS set is an integer multiple of a length of the X slots.
A base station (BS) of transmitting physical downlink control channel (PDCCH) in a wireless communication system, the BS comprising:
- at least one transceiver;
- at least one processor;
- and
- at least one memory operably connected to the at least one processor and configured to store instructions causing, when executed, the at least one processor to perform operations comprising:
- receiving, through the at least one transceiver, a capability to monitoring PDCCH according to combination (X, Y),
- wherein X and Y are numbers of consecutive slots;
- transmitting, through the at least one transceiver, PDCCH for a UE-specific Search Space (USS) set in any slot of the Y slots, and
- wherein the Y slots are within the X slots and the X and the Y are positive integer, and
- wherein a monitoring periodicity of the USS set is an integer multiple of a length of the X slots.
