Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] Referring to FIG. 3 , it is a schematic diagram of a method for sending control signaling and reference signals based on a broadband single-carrier system according to an embodiment of the present invention. As shown in the figure, a subframe contains 9 data blocks, including 4 SBs and 5 LBs.

[0022] Among them, the first data block is SB1. At the front end of the subframe, SB1 is used to send control signaling, and after SB1 is SB2, and SB2 is used to send a reference signal. The reference signal is used for channel estimation of control signaling and data transmission Or for channel quality measurement, five long data blocks of LB1 to LB5 after SB2, use LB1 to LB5 to send user data or signaling related to data transmission, and SB3 after LB5, use SB3 to send the same as SB2 The reference signal is SB4 after SB3, and SB4 is used as the switching gua...

Abstract

The invention discloses a transmitting method of control signallings and reference signals based on a broadband single carrier system, and a transmitting signal unit in terms of a subframe, wherein, each subframe comprises one or more long data blocks and short data blocks for transmitting control signallings or reference signals. The method comprises following steps: utilizing a first short data block to transmit control signallings at the most front end of each subframe; after the first short data block, utilizing a second short data block to transmit reference signals; after the second short data block, utilizing the first, the second, the third, the fourth, the fifth long data blocks to transmit user data or signallings relating with data transmission; after the fifth long data block, utilizing the third short data block to transmit reference signals; after the third short data block, utilizing the fourth short data block as a switching guard interval. The disadvantages of too long delay time of control signalling demodulation and resource waste in the prior art are overcame by using the method of the invention.

Description

technical field [0001] The invention relates to the field of digital communication, in particular to a method for sending control signaling and reference signals based on a broadband single-carrier system. Background technique [0002] For a communication system, layer 1 / layer 2 control signaling is very necessary for channel scheduling, link adaptation, and hybrid retransmission that depend on the signaling. Layer 1 / layer 2 signaling mainly includes: (1) signaling related to data transmission, such as data transmission format, hybrid retransmission information, etc.; (2) signaling unrelated to data transmission, such as response and channel quality indication information , Scheduling requests for data transmission, etc. [0003] In E-UTRA, signals are sent in units of subframes. In the traditional control signaling and data transmission time division multiplexing transmission method, an uplink subframe contains 8 data blocks, consisting of 2 SB (Short Block, short data bl...
