Abstract
The present disclosure relates to a 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE).
Claims15
A method performed by a base station, the method comprising:
- transmitting, to a user equipment (UE), feedback resource allocation information;
- transmitting, to the UE, a transport block;
- receiving, from the UE, hybrid automatic repeat request (HARQ) feedback information for the transport block based on the feedback resource allocation information;
- mapping the transport block and a protocol data unit (PDU) based on the HARQ feedback information, wherein a transmission status of each PDU in the transport block is determined based on the HARQ feedback information:
- storing information on the mapping;
- retransmitting, to the UE, the transport block based on the information on the mapping;
- receiving, from the UE, repeated HARQ feedback information based on the feedback resource allocation information;
- and
- determining whether to perform another retransmission of the transport block based on the repeated HARQ feedback information.
6 more elements
A method performed by a user equipment (UE), the method comprising:
- receiving, from a base station, feedback resource allocation information;
- receiving, from the base station, a transport block;
- allocating a feedback resource based on the feedback resource allocation information;
- transmitting, to the base station, hybrid automatic repeat request (HARQ) feedback information for the transport block in the allocated resource;
- receiving, from the base station, a retransmission of the transport block based on information on mapping based on the HARQ feedback information, wherein a transmission status of each PDU in the transport block is determined based on the HARQ feedback information;
- and
- transmitting, to the base station, repeated HARQ feedback information based on the feedback resource allocation information, wherein the information on mapping is obtained by mapping the transport block and a protocol data unit (PDU), and
- wherein whether to perform another retransmission, by the base station, the transport block is determined based on the repeated HARQ feedback information.
5 more elements
A base station comprising:
- a transceiver configured to transmit or receive at least one signal;
- and
- a controller coupled to the transceiver,
- wherein the controller is configured to:
- transmit, to a user equipment (UE), feedback resource allocation information;
- transmit, to the UE, a transport block;
- receive, from the UE, hybrid automatic repeat request (HARQ) feedback information for the transport block based on the feedback resource allocation information,
- map the transport block and a protocol data unit (PDU) based on the HARQ feedback information wherein a transmission status of each PDU in the transport block is determined based on the HARQ feedback information,
- store information on the mapping,
- retransmit, to the UE, the transport block based on the information on the mapping,
- receive, from the UE, repeated HARQ feedback information based on the feedback resource allocation information, and
- determine whether to perform another retransmission of the transport block based on the repeated HARQ feedback information.
9 more elements
A user equipment (UE), comprising:
- a transceiver configured to transmit or receive at least one signal;
- and
- a controller coupled to the transceiver,
- wherein the controller is configured to:
- receive, from a base station, feedback resource allocation information;
- receive, from the base station, a transport block;
- allocate a feedback resource based on the feedback resource allocation information;
- transmit, to the base station, hybrid automatic repeat request (HARQ) feedback information for the transport block in the allocated resource;
- receive, from the base station, a retransmission of the transport block based on information on mapping based on the HARQ feedback information, wherein a transmission status of each PDU in the transport block is determined based on the HARQ feedback information;
- and
- transmit, to the base station, repeated HARQ feedback information based on the feedback resource allocation information,
- wherein the information on mapping is obtained by mapping the transport block and a protocol data unit (PDU), and
- wherein whether to perform another retransmission, by the base station, the transport block is determined based on the repeated HARQ feedback information.
