Abstract
Methods, systems, and devices for wireless communications are described. In some systems one or more first user equipment (UE) may be configured to relay transmissions to second user equipment upon reception of a negative acknowledgment (NACK) from the second user equipment. In other systems, one or more UEs may be configured to receive transmissions relayed from other UEs in response to a NACK.
Claims23
A method for wireless communications at a first user equipment (UE), comprising:
- receiving a data packet sent to a second UE;
- identifying a failure of the second UE to receive the data packet;
- and
- transmitting the received data packet to the second UE.
A method for wireless communications at a first user equipment (UE), comprising:
- receiving control information from a first device, the control information including an identification of resources for receiving a data transmission;
- identifying a failure to receive the data transmission from the first device on the identified resources;
- transmitting a negative acknowledgement;
- and
- receiving a retransmission of the data transmission from a second device.
A method for wireless communications at a base station, comprising:
- configuring first and second user equipment (UEs) for NACK triggered relay;
- transmitting a data packet to the first UE;
- identifying a failure of the first UE to receive the data packet;
- and
- retransmitting the data packet to the first UE.
Apparatus for wireless communication, comprising:
- a processor;
- memory in electronic communication with the processor;
- and
- instructions stored in the memory and executable by the processor to cause the apparatus to:
- receive a data packet sent to a second UE;
- identify a failure of the second UE to receive the data packet;
- and
- transmit the received data packet to the second UE.
