Abstract
Embodiments herein provide a method for managing HARQ procedure for multiple numerologies multiplexing in a wireless communication network. The method includes transmitting, by a User Equipment (UE), capability parameters of the UE to a Base Station (BS). Further, the method includes receiving, by the UE, a plurality of HARQ configuration parameters corresponding to the capability parameters of the UE from the BS, and perfuming, by the UE, one of an individual HARQ process and a shared HARQ process based on the plurality of HARQ configuration parameters received from the BS.
Claims20
A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving, from a base station, information for indicating a joint feedback or a separate feedback for a hybrid automatic repeat request (HARQ) procedure;
- in case that the information indicates the separate feedback, performing a HARQ-acknowledgement (ACK) transmission for a first node and a HARQ-ACK transmission for a second node, separately;
- and
- in case that the information indicates the joint feedback, performing a HARQ-ACK transmission associated with combined information, on one physical uplink control channel (PUCCH),
- wherein the combined information is generated for physical downlink shared channel (PDSCH) receptions of the first node and the second node, and
- wherein the combined information is generated by jointly designing a HARQ-ACK codebook for each of the first node and the second node.
A method performed by a base station in a wireless communication system, the method comprising:
- transmitting, to a user equipment (UE), information for indicating a joint feedback or a separate feedback for a hybrid automatic repeat request (HARQ) procedure;
- in case that the information indicates the separate feedback, receiving a HARQ-acknowledgement (ACK), transmission for a first node and a HARQ-ACK transmission for a second node, separately;
- and
- in case that the information indicates the joint feedback, receiving a HARQ-ACK transmission associated with combined information, on one physical uplink control channel (PUCCH),
- wherein the combined information is multiplexed for multiple physical downlink shared channel, PDSCH, transmissions of the first node and the second node.
A user equipment (UE) in a wireless communication system, comprising:
- at least one transceiver;
- and
- at least one processor coupled with the transceiver,
- wherein the at least one processor is configured to:
- receive, from a base station, information for indicating a joint feedback or a separate feedback for a hybrid automatic repeat request (HARQ) procedure;
- in case that the information indicates the separate feedback, perform a HARQ-acknowledgement (ACK) transmission for a first node and a HARQ-ACK transmission for a second node, separately;
- and
- in case that the information indicates the joint feedback, perform a HARQ-ACK transmission associated with combined information, on one physical uplink control channel (PUCCH),
- wherein the combined information is generated for physical downlink shared channel (PDSCH) receptions of the first node and the second node, and
- wherein the combined information is generated by jointly designing a HARQ-ACK codebook for each of the first node and the second node.
A base station in a wireless communication system, comprising:
- a transceiver;
- and
- at least one processor coupled with the transceiver,
- wherein the at least one processor is configured to:
- transmit, to a user equipment (UE), information for indicating a joint feedback or a separate feedback for a hybrid automatic repeat request (HARQ) procedure;
- in case that the information indicates the separate feedback, receive a HARQ-acknowledgement (ACK), transmission for a first node and a HARQ-ACK transmission for a second node, separately;
- and
- in case that the information indicates the joint feedback, receive a HARQ-ACK transmission associated with combined information, on one physical uplink control channel (PUCCH),
- wherein the combined information is multiplexed for multiple physical downlink shared channel, PDSCH, transmissions of the first node and the second node.
