METHOD AND BASE STATION FOR TRANSMITTING A DATA BLOCK

摘要

A method and a base station of transmitting a data block are provided. At least one data block is transmitted via at least one of at least two downlink frequency bands. A modulation symbol and N spreading sequences are received. Acknowledgement/negative acknowledgement (A/N) information is determined in accordance with the modulation symbol and the N spreading sequences. The modulation symbol and the N spreading sequences jointly determine the A/N information. And the at least one data block may be retransmitted depending on the A/N information determined.

1. A method, comprising:
receiving, by a terminal device, at least one data block via at least one of at least two downlink frequency bands; determining, by the terminal device, acknowledgement/negative acknowledgement (A/N) information, wherein the A/N information indicates whether the at least one data block is correctly detected by the terminal device; determining, by the terminal device, a modulation symbol and a transmission resource according to the A/N information in accordance, wherein the A/N information is corresponding to the modulation symbol and the transmission resource; and transmitting, by the terminal device, the modulation symbol on the transmission resource via N antenna ports, wherein N is an integer greater than or equal to 2.
