Embodiment 1

[0063] 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 Get the corresponding modulation method And the control signaling that needs to be transmitted in the current subframe is First calculate the target length of each uplink control signaling, which are Q ACK , Q RI , Q CQI ,according to Choose different encoding methods, and the encoded information is as follows: Calculate data information on transmission block 1 G 1 = N symb PUSCH 1 × M sc PUSCH 1 × Q m 1 - Q...

Embodiment 2

[0066] 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 the UE determines to transmit uplink control signaling on TB2, according to Get the corresponding modulation method And the control signaling that needs to be transmitted in the current subframe is First calculate the target length of each uplink control signaling, which are Q ACK , Q RI , Q CQI ,according to Choose different encoding methods, and the encoded information is as follows: Calculate data information on transmission block 2 G 2 = N symb PUSCH 2 × ...

Embodiment 3

[0068] Assuming that PUSCH has two transport blocks TB1 and TB2, the indexes corresponding to the two transport blocks are respectively and The UE determines to transmit uplink control signaling on TB1, according to Get the corresponding modulation method And the control signaling that needs to be transmitted in the current subframe is First calculate the target length of each uplink control signaling, which are Q ACK , Q RI , Q CQI ,according to Choose different encoding methods, and the encoded information is as follows: Calculate data information on transmission block 1 G 1 = N symb PUSCH 1 × M sc PUSCH 1 × Q m 1 - Q CQI - ...

Abstract

The present invention discloses a method for transmitting uplink control signaling in a Physical Uplink Shared Channel (PUSCH). The method includes: when two transport blocks / codewords are transmitted in the PUSCH, mapping uplink control signaling to the layer corresponding to one of the two transport blocks / codewords to transmit. The present invention also discloses an apparatus for transmitting uplink control signaling in the PUSCH. The apparatus includes: a mapping unit, used for mapping uplink control signaling to the layer corresponding to one of two transport blocks / codewords when the two transport blocks / codewords are transmitted in the PUSCH; and a transmission unit, used for transmitting the uplink control signaling. The present invention effectively solves the problem of transmitting uplink control signaling in the PUSCH when the PUSCH uses spatial multiplexing in an LTE-A system, and ensures the data capacity. The channel quality corresponding to the transport blocks selected in various ways is relatively good, thereby ensuring the transmission quality of the uplink control signaling.

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 through a Physical Uplink Shared Channel (PUSCH, Pysical 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 / Negative Acknowledgment), and information reflecting the state of the downlink physical channel (CSI, Channel State Information) in three forms: channel quality indication (CQI, Channel Quality Indication), precoding matrix indication (PMI, Pre-coding Matrix Indicator), rank indication (RI, Rank Indicator). [0003] In the LTE system, the ACK / NACK response message is transmitted in the format l / l a / lb (PUCCH formatI / lal / b) on the physical uplink control channel (PUCCH, Physical Uplink Co...
