Abstract
Apparatus, methods, and computer-readable media for facilitating usage of memory of helping UEs during sidelink retransmission are disclosed herein. An example method for wireless communication at a first user equipment (UE) includes receiving, from a wireless device, a first packet and a second packet for sidelink retransmission to at least one second UE, the second packet being received after the first packet. The example method also includes dropping the first packet or the second packet prior to retransmission based on at least one of a packet priority or an indication from the wireless device.
Claims26
A method of wireless communication at a first user equipment (UE), comprising:
- receiving, from a wireless device, a first transport block and a second transport block for sidelink retransmission to at least one second UE, the second transport block being received after the first transport block, the at least one second UE being different than the wireless device;
- receiving a first priority and a second priority in group information from a base station;
- dropping the first transport block or the second transport block prior to retransmission to the at least one second UE based on at least one of a transport block priority or an indication from the wireless device, wherein the first transport block is dropped when the first priority of the first transport block is less than the second priority of the second transport block, or the second transport block is dropped when the second priority is less than the first priority;
- and
- retransmitting, from the first UE to the at least one second UE, a remaining transport block that is not dropped from the first transport block and the second transport block received from the wireless device.
An apparatus for wireless communication at a first user equipment (UE), comprising:
- a memory;
- and
- at least one processor coupled to the memory and configured to:
- receive, from a wireless device, a first transport block and a second transport block for sidelink retransmission to at least one second UE, the second transport block being received after the first transport block, the at least one second UE being different than the wireless device;
- receive a first priority and a second priority in group information from a base station;
- drop the first transport block or the second transport block prior to retransmission to the at least one second UE based on at least one of a transport block priority or an indication from the wireless device, wherein the first transport block is dropped when the first priority of the first transport block is less than the second priority of the second transport block, or the second transport block is dropped when the second priority is less than the first priority;
- and
- retransmit, from the first UE to the at least one second UE, a remaining transport block that is not dropped from the first transport block and the second transport block received from the wireless device.
A method of wireless communication at a wireless device comprising a base station or a programmable logic controller (PLC), the method comprising:
- transmitting, to a first user equipment (UE), a first transport block and a second transport block for sidelink retransmission to at least one additional UE, the second transport block being transmitted after the first transport block, the at least one additional UE being different than the first UE;
- transmitting a first priority and a second priority in group information to the first UE;
- and
- transmitting an indication to the first UE to drop the first transport block or the second transport block from the sidelink retransmission to the at least one additional UE, wherein the indication comprises a priority based indication, and wherein the first transport block is indicated to be dropped when the first priority of the first transport block is less than the second priority of the second transport block, or the second transport block is indicated to be dropped when the second priority is less than the first priority.
An apparatus for wireless communication at a wireless device comprising a base station or a programmable logic controller (PLC), comprising:
- a memory;
- and
- at least one processor coupled to the memory and configured to:
- transmit, to a first user equipment (UE), a first transport block and a second transport block for sidelink retransmission to at least one additional UE, the second transport block being transmitted after the first transport block, the at least one additional UE being different than the first UE;
- transmit a first priority and a second priority in group information to the first UE;
- and
- transmit an indication to the first UE to drop the first transport block or the second transport block from the sidelink retransmission to the at least one additional UE, wherein the indication comprises a priority based indication, and wherein the first transport block is indicated to be dropped when the first priority of the first transport block is less than the second priority of the second transport block, or the second transport block is indicated to be dropped when the second priority is less than the first priority.
