Uplink Data Transmission Method and Apparatus

The uplink data transmission apparatus according to claim ii, wherein the instructions to cause the transmitter to transmit the first uplink data and the jointly coded data to the network device comprise instructions to cause the transmitter to transmit the first uplink data to the network device on a first transmission resource, and transmit the jointly coded data to the network device on a second transmission resource different from the first transmission resource.

The uplink data transmission apparatus according to claim ii, further comprising a receiver configured to receive first instruction information from the network device before the obtaining the second uplink data of the second terminal device, wherein the first instruction information instructs the first terminal device to perform transmit diversity transmission;

• and
• 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 according to the first instruction information.

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.

The uplink data transmission apparatus according to claim ii, wherein the program further includes instructions to add a cyclic redundancy check (CRC) code to the first uplink data before the transmitting the first uplink data and the jointly coded data to the network device, wherein the CRC code is scrambled using an identifier of the second terminal device;

• and
• wherein the instructions to cause the transmitter to transmit the first uplink data and the jointly coded data to the network device comprise instructions to cause the transmitter to transmit the first uplink data with the scrambled CRC code and the jointly coded data using transmit diversity transmission with the second terminal device.
