Uplink data transmission method and apparatus
First Claim
1. A method, comprising:
- obtaining, by a first terminal device, second uplink data of a second terminal device;
performing, by the first terminal device, joint coding processing on first uplink data of the first terminal device and on the second uplink data, wherein the performing the joint coding processing generates jointly coded data that is based on the first uplink data and the second uplink data; and
transmitting, by the first terminal device, the first uplink data and the jointly coded data to a network device, wherein the first uplink data is transmitted to the network device separately from the jointly coded data.

Abstract
A method includes obtaining, by a first terminal device, second uplink data of a second terminal device, performing, by the first terminal device, joint coding processing on first uplink data of the first terminal device and on the second uplink data, where the performing the joint coding processing generates jointly coded data that is based on the first uplink data and the second uplink data, and transmitting, by the first terminal device, the first uplink data and the jointly coded data to a network device, where the first uplink data is transmitted to the network device separately from the jointly coded data. The first uplink data may be transmitted on a first transmission resource, and the jointly coded data to the network device may be transmitted on a second transmission resource different from the first transmission resource.

18. The uplink data transmission apparatus according to claim ii, the program further includes instructions to, before the obtaining the second uplink data, cause the transmitter to transmit a transmit diversity transmission request to the second terminal device, wherein the transmit diversity transmission request requests that the second terminal device perform transmit diversity transmission with the first terminal device;
- and
wherein the uplink data transmission apparatus further includes a receiver configured to receive a transmit diversity transmission response transmitted by the second terminal device in response to the transmit diversity transmission request; wherein the instructions to cause the transmitter to transmit the first uplink data and the jointly coded data to a network device comprise instructions to cause the transmitter to transmit the first uplink data and the jointly coded data using transmit diversity transmission with the second terminal device in response to the transmit diversity transmission response. - View Dependent Claims (19)
