在无线通信系统中发送用于确认和分类0位的分集

Transmit diversity for acknowledgement and category 0 bits in a wireless communication system
Abstract:
A method of transmitting acknowledgement/nonacknowledgement (ACK/NACK) signals including multiplexing ACK/NACK signals; and repeatedly transmitting for predetermined times the multiplexed signal with each of repetitions of transmitting the multiplexed signal being spread in a frequency domain and being mapped to a plurality of discrete resource units each having a pair of neighboring subcarriers and a predetermined number of Orthogonal Frequency Division Multiplexing (OFDM) control symbols.A method for transmitting Category 0 bits, including modulating the Category 0 bits; repeatedly transmitting the modulated Category 0 bits with each of repetitions of transmitting the modulated Category 0 bits being spread in a frequency domain and being mapped to a plurality of discrete resource units each having a pair of subcarriers and a predetermined number of OFDM control symbols; and mapping the modulated Category 0 bits by a frequency selective transmit diversity (FSTD).
Abstract(Chinese):

一种发送包括复用ACK / NACK信号的确认/非确认（ACK / NACK）信号的方法; 并且在多个信号中重复发送多路复用信号，每次重复发送多路复用信号在频域中扩展，并被映射到多个离散资源单元，每个离散资源单元具有一对相邻子载波和预定数量的正交频分复用 （OFDM）控制符号。 一种用于传输类别0位的方法，包括调制类别0位; 重复地发送调制的分类0比特，其中每个重复发送调制的分类0比特在频域中扩展，并被映射到多个离散资源单元，每个离散资源单元具有一对子载波和预定数量的OFDM控制符号; 并通过频率选择性发射分集（FSTD）将调制的0类比特映射。
