Method and apparatus for transmitting and receiving semi persistent scheduling PDSCH in wireless communication system
A method and apparatus for transmitting and receiving a semi-persistent scheduling PDSCH in a wireless communication system is disclosed. A method according to an embodiment of the present disclosure may include receiving, from a base station, respective configuration information related to one or more SPS configurations; receiving, from the base station, respective DCI for activating the one or more SPS configurations; and receiving, from the base station, the same TB through SPS PDSCH reception in a first SPS PDSCH resource set and a second SPS PDSCH resource set for the one or more SPS configurations.
1 . A method comprising:
receiving, by a user equipment (UE) from a base station, respective configuration information related to one or more semi-persistent scheduling (SPS) configurations;
receiving, by the UE from the base station, respective downlink control information (DCI) for activating the one or more SPS configurations; and
receiving, by the UE from the base station, the same transport block (TB) through SPS PDSCH reception in a first SPS physical downlink shared channel (PDSCH) resource set and a second SPS PDSCH resource set for the one or more SPS configurations,
wherein different transmission configuration indication (TCI) states are configured for the first SPS PDSCH resource set and the second SPS PDSCH resource set.
2 . The method of claim 1 , wherein the first SPS PDSCH resource set and the second SPS PDSCH resource set are associated with a single SPS configuration.
3 . The method of claim 2 , wherein the same hybrid automatic repeat request (HARQ) process identifier (ID) is determined for the first SPS PDSCH resource set and the second SPS PDSCH resource set in the same SPS PDSCH transmission period.
4 . The method of claim 1 , wherein the first SPS PDSCH resource set and the second SPS PDSCH resource set are associated with a first SPS configuration and a second SPS configuration, respectively.
5 . The method of claim 4 , wherein SPS PDSCH transmission periods for the first SPS configuration and the second SPS configuration are aligned.
6 . The method of claim 5 , further comprising:
receiving a single medium access control (MAC) control element (CE) for activation and/or deactivation of TCI states for the first SPS PDSCH resource set and the second SPS PDSCH resource set.
7 . The method of claim 6 , wherein a TCI state indicated by the MAC CE is activated and/or deactivated from an initial SPS PDSCH transmission period after the MAC CE is received or an ACK (acknowledgement) for the MAC CE is transmitted.
8 . The method of claim 1 , wherein physical uplink control channel (PUCCH) resources for transmitting hybrid automatic repeat request-acknowledgement (HARQ-ACK) information for the first SPS PDSCH resource set and the second SPS PDSCH resource set are configured as the same resource or individually determined as different resources.
9 . A user equipment (UE) comprising:
at least one transceiver for transmitting and receiving a wireless signal; and
at least one processor for controlling the at least one transceiver,
wherein the at least one processor is configured to:
receive, from a base station, respective configuration information related to one or more semi-persistent scheduling (SPS) configurations;
receive, from the base station, respective downlink control information (DCI) for activating the one or more SPS configurations; and
receive, from the base station, the same transport block (TB) through SPS PDSCH reception in a first SPS physical downlink shared channel (PDSCH) resource set and a second SPS PDSCH resource set for the one or more SPS configurations,
wherein different transmission configuration indication (TCI) states are configured for the first SPS PDSCH resource set and the second SPS PDSCH resource set.
10 . A base station comprising:
at least one transceiver for transmitting and receiving a wireless signal; and
at least one processor for controlling the at least one transceiver,
wherein the at least one processor is configured to:
transmit, to a user equipment (UE), respective configuration information related to one or more semi-persistent scheduling (SPS) configurations;
transmit, to the UE, respective downlink control information (DCI) for activating the one or more SPS configurations; and
transmit, to the UE, the same transport block (TB) through SPS PDSCH transmission in a first SPS physical downlink shared channel (PDSCH) resource set and a second SPS PDSCH resource set for the one or more SPS configurations,
wherein different transmission configuration indication (TCI) states are configured for the first SPS PDSCH resource set and the second SPS PDSCH resource set.
