Method and device for transmitting/receiving wireless signal in wireless communication system
The present invention relates to a wireless communication system, and may comprise receiving a first transport block in a first semi-persistent scheduling (SPS) resource allocated for an SPS operation, receiving scheduling information that indicates the retransmission of the first transport block, and receiving, based on a processing time of a user equipment, the first transport block (TB) in one or more second SPS resources using a hybrid automatic repeat request (HARQ) process related to the first SPS resource.
1 . A method comprising:
receiving configuration information related to semi-persistent scheduling (SPS), wherein the configuration information includes information related to a periodicity for the SPS and information related to the number of hybrid automatic repeat request (HARQ) processes configured for the SPS;
receiving a downlink data based on the configuration information;
receiving downlink control information (DCI) for scheduling retransmission of the downlink data; and
receiving the retransmission of the downlink data based on a validity of the configuration information,
wherein the configuration information is determined as valid, based on a value obtained by multiplying the number of the HARQ processes by the periodicity, which is greater than a processing time for the DCI.
2 . The method of claim 1 ,
wherein the number of one or more resources based on the configuration information is determined based on the periodicity and the processing time.
3 . The method of claim 2 ,
wherein, based on the processing time and the periodicity which are T and P, respectively, the number X of the one or more resources is determined by an equation of X=ceil(T/P).
4 . A user equipment (UE) comprising:
a memory storing instructions;
a transceiver; and
a processor,
wherein the processor is configured to execute the instructions to perform operations comprising:
receiving configuration information related to semi-persistent scheduling (SPS), wherein the configuration information includes information related to a periodicity for the SPS and information related to the number of hybrid automatic repeat request (HARQ) processes configured for the SPS,
receiving a downlink data based on the configuration information,
receiving downlink control information (DCI) for scheduling retransmission of the downlink data, and
receiving the retransmission of the downlink data based on a validity of the configuration information,
wherein the configuration information is determined as valid, based on a value obtained by multiplying the number of the HARQ processes by the periodicity, which is greater than a processing time for the DCI.
5 . An apparatus for a user equipment, the apparatus comprising:
at least one processor; and
at least one computer memory operably connected to the at least one processor and configured to cause, based on execution, the at least one processor to perform operations comprising:
receiving configuration information related to semi-persistent scheduling (SPS), wherein the configuration information includes information related to a periodicity for the SPS and information related to the number of hybrid automatic repeat request (HARQ) processes configured for the SPS,
receiving a downlink data based on the configuration information,
receiving downlink control information (DCI) for scheduling retransmission of the downlink data, and
receiving the retransmission of the downlink data based on a validity of the configuration information,
wherein the configuration information is determined as valid, based on a value obtained by multiplying the number of the HARQ processes by the periodicity, which is greater than a processing time for the DCI.
