Embodiment 1

[0066] Assuming that PUSCH has two transport blocks TB1 and TB2, the transport block with better channel conditions on the base station side is always numbered as TB1, and the user terminal will always determine to transmit uplink control signaling on TB1, according to I MCS 1 Get the corresponding modulation mode Q m 1 , and the control signaling that needs to be transmitted in the current subframe is [O 0 ACK , O 1 ACK ,...O 3 ACK ], [O 0 RI , O 1 RI ], [O 0 CQI , O 1 CQI ,...O 10 CQI ], first calculate the target length of each uplink control signaling, respectively Q ACK , Q RI , Q CQI , according to Q m 1 Choose different encoding methods, and the encoded information is as follows: Calculate data information on transmission block 1 Then the encoded data and reuse, get then put and Perform interleaving to obtain information after multiplexing of uplink control signaling and uplink data The information is transmitted on the transpo...

Embodiment 2

[0068] Assuming that PUSCH has two transport blocks TB1 and TB2, the base station indicates that the channel quality corresponding to transport block 2 is relatively good through 1-bit signaling in the downlink control signaling (the base station notifies the user terminal that the channel condition is better through real-time indication information transport block), so UE determines to transmit uplink control signaling on TB2, according to I MCS 2 Get the corresponding modulation mode Q m 2 , and the control signaling that needs to be transmitted in the current subframe is [O 0 ACK , O 1 ACK ,...O 3 ACK ], [O 0 RI , O 1 RI ], [O 0 CQI , O 1 CQI ,...O 10 CQI ], first calculate the target length of each uplink control signaling, respectively Q ACK , Q RI , Q CQI , according to Q m 2 Choose different encoding methods, and the encoded information is as follows: Calculate data information on transmission block 2 Then the encoded data and reuse, ge...

Abstract

The invention discloses a method for transmitting an uplink control signaling on a physical uplink shared channel, comprising the following steps: when two transmission blocks / code streams exist on the physical uplink shared channel (PUSCH), mapping the uplink control signaling onto a corresponding layer of one of the transmission blocks / code streams for transmission. The invention simultaneously discloses a device for transmitting the uplink control signaling in the physical uplink shared channel, which comprises a mapping device and a transmission unit, wherein the mapping device is used for mapping the uplink control signaling onto the corresponding layer of one of the transmission blocks / code streams when two transmission blocks exist on the physical uplink shared channel (PUSCH); and the transmission unit is used for transmitting the uplink control signaling. The invention effectively solves the problems for the transmission of the uplink signaling on the PUSCH under the condition that the PUSCH adopts space division multiplexing in an LTE-A system, and guarantees the capacity of the data, and as channel quality corresponding to the transmission blocks selected by various manners is relatively better generally, the transmission quality of the uplink control signaling can be guaranteed.

Description

technical field [0001] The present invention relates to the transmission technology of uplink control signaling, in particular to a method and device for transmitting uplink control signaling on a Physical Uplink Shared Channel (PUSCH, 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 correct / error response messages (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, Channel Quality Indication), Precoding Matrix Indication (PMI, Pre-coding Matrix Indicator), and Rank Indication (RI, Rank Indicator). [0003] In the LTE system, the ACK / NACK response message is transmitted on the physical uplink control channel (PUCCH, PhysicalUplink Control Channel) in format 1 / 1a / 1b (PUCCH f...
