Method for performing uplink transmission, user equipment, processing device, storage medium, computer program, and method and base station for receiving uplink transmission
A UE performs operations for: receiving a configuration for a reference resource region for an uplink cancellation indication; receiving scheduling information for scheduling uplink transmission on a frequency band including the reference resource region; receiving uplink cancellation indication information related to the reference resource region; and determining whether to cancel the uplink transmission on the basis of whether a first resource for the uplink transmission overlaps with a second resource, indicated by the uplink cancellation indication information, among resources in the reference resource region. The reference resource region may include one or more RB sets, each including a plurality of interlaced RBs. The uplink cancellation indication information may include a first information part pertaining to at least one of the plurality of interlaced RBs in the one or more RB sets.

receiving uplink cancellation indication information related to the reference resource region; and
based on whether a first resource for the uplink transmission overlaps with a second resource indicated by the uplink cancellation indication information among resources in the reference resource region, determining whether to cancel the uplink transmission,
wherein the reference resource region includes one or more resource block (RB) sets, each of which includes a plurality of interlaced RBs, and
wherein the uplink cancellation indication information includes a first information part on at least one of the plurality of interlaced RBs in each of the one or more RB sets.
2 . The method of claim 1 , comprising, based on the first resource for the uplink transmission not overlapping with the second resource indicated by the uplink cancellation indication information, performing the uplink transmission.
3 . The method of claim 1 , comprising, based on the first resource for the uplink transmission overlapping with the second resource indicated by the uplink cancellation indication information, performing the uplink transmission.
4 . The method of claim 1 , wherein the uplink cancellation indication information includes a second information part indicating one of the one or more RB sets.
5 . The method of claim 1 , wherein the frequency band is an unlicensed band.
6 . The method of claim 5 , comprising, based on i) the first resource for the uplink transmission overlapping with the second resource indicated by the uplink cancellation indication information and ii) the uplink transmission having a low priority, performing the uplink transmission.
7 . The method of claim 5 , comprising, based on i) the first resource for the uplink transmission overlapping with the second resource indicated by the uplink cancellation indication information and ii) the uplink transmission having a high priority, performing the uplink transmission.
8 . The method of claim 7 , comprising, based on at least one bit of the first information part not being zero, performing the uplink transmission without a listen-before-talk (LBT) process.
9 . The method of claim 5 , comprising:
based on all bits of the first information part being zero, performing a listen-before-talk (LBT) process; and
based on success of the LBT process, performing the uplink transmission.
10 . A user equipment (UE) configured to perform uplink transmission in a wireless communication system, the UE comprising:
at least one transceiver;
at least one processor; and
at least one computer memory operably connected to the at least one processor and configured to store instructions that, when executed, cause the at least one processor to perform operations comprising:
receiving a configuration for a reference resource region for an uplink cancellation indication;
receiving scheduling information for scheduling the uplink transmission on a frequency band including the reference resource region;
receiving uplink cancellation indication information related to the reference resource region; and
based on whether a first resource for the uplink transmission overlaps with a second resource indicated by the uplink cancellation indication information among resources in the reference resource region, determining whether to cancel the uplink transmission,
wherein the reference resource region includes one or more resource block (RB) sets, each of which includes a plurality of interlaced RBs, and
wherein the uplink cancellation indication information includes a first information part on at least one of the plurality of interlaced RBs in each of the one or more RB sets.
11 . A method of receiving, by a base station (BS), uplink transmission from a user equipment (UE) in a wireless communication system, the method comprising:
transmitting a configuration for a reference resource region for an uplink cancellation indication;
transmitting to the UE scheduling information for scheduling the uplink transmission on a frequency band including the reference resource region;
transmitting uplink cancellation indication information related to the reference resource region; and
based on whether a first resource for the uplink transmission overlaps with a second resource indicated by the uplink cancellation indication information among resources in the reference resource region, determining whether to receive the uplink transmission,
wherein the reference resource region includes one or more resource block (RB) sets, each of which includes a plurality of interlaced RBs, and
wherein the uplink cancellation indication information includes a first information part on at least one of the plurality of interlaced RBs in each of the one or more RB sets.
12 . A base station (BS) configured to receive uplink transmission from a user equipment (UE) in a wireless communication system, the BS comprising:
at least one transceiver;
at least one processor; and
at least one computer memory operably connected to the at least one processor and configured to store instructions that, when executed, cause the at least one processor to perform operations comprising:
transmitting a configuration for a reference resource region for an uplink cancellation indication;
transmitting to the UE scheduling information for scheduling the uplink transmission on a frequency band including the reference resource region;
transmitting uplink cancellation indication information related to the reference resource region; and
