Abstract

The invention provides a system and a method for transferring upstream control signals on a physical ascending sharing channel; the method comprises the steps of: respectively coding the upstream control signals needing to be transferred and the data information which a transmission block corresponds to, intercepting the corresponding coded information according to the target length; when a transferring block corresponds to a plurality of layers, the information of each layer to be transferred on the transferring block is interweaved; the interweaved information is transferred on the layer which the physical upstream sharing channel (PUSCH) corresponds to; the information on each layer comprises an upstream control signaling information; or the information on each layer comprises the data information and upstream control signaling. The technical scheme of the invention can realize the transmission of the upstream control signals on the PUSCH when the PUSCH adopts the space division multiplexing in the LTE-A system.

Description

technical field [0001] The invention relates to the field of digital communication, in particular to a system and method for transmitting uplink control signaling on a physical uplink shared channel. Background technique [0002] In the long-term evolution system (LTE: Long Term Evolution), the control signaling that needs to be transmitted in the uplink includes a correct / error response message (ACK / NACK: Acknowledgment / NegativeAcknowledgment), and information reflecting the state of the downlink physical channel (CSI: Channel StateInformation) There are three forms: channel quality indication (CQI: Channels quality indication), precoding matrix indication (PMI: Pre-coding Matrix Indicator), rank indication (RI: RankIndicator). [0003] In the LTE system, the ACK / NACK response message is transmitted on the physical uplink control channel (PUCCH: Physical Uplink Control) in format 1 / 1a / 1b (PUCCH format1 / 1a1 / b). If the terminal (UE: User Equipment) needs to send an uplink Fo...
