Embodiment Construction

[0079] In the LTE system, the uplink control signaling and uplink data multiplex the radio frame as follows: figure 1 shown. The channel coding process when uplink control signaling and uplink data are multiplexed in the LTE system is as follows: figure 2 As shown, uplink data is transmitted in the form of TB (Transport Block, transport block), and TB passes through CRC attachment (cyclic redundancy check addition), Code block segmentation (code block segmentation) and Code blockCRC attachment (sub-block CRC addition), Channel coding (channel coding), Rate matching (rate matching), Code block concatenation (code block synthesis) and post-coding CQI / PMI multiplexing of uplink data and control signaling, and finally through channel interleaving to encode the ACK / NACK, RI and uplink data are multiplexed together. The PUSCH transmission mode in the LTE system is as follows image 3 As shown, the PUSCH corresponds to only one transport block or codeword stream.

Abstract

The invention discloses a transmission method of uplink control signaling and a device thereof, relating the field of mobile communication and solving the problem of lacking a mechanism for transmitting uplink control signaling on space division multiplexing (SDM) PUSCH. The method comprises: determining the uplink control signaling target length corresponding to each transmission block or code stream; respectively obtaining the multiplexing information after uplink control signaling to be transmitted on each transmission block or code stream are multiplexed with uplink data; and transmitting the multiplexing information corresponding to each transmission block or code stream on PUSCH. The technical scheme provided by the invention is suitable for the transmission of uplink control signaling in LTE systems.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method and device for transmitting uplink control signaling. Background technique [0002] In the LTE system (Long Term Evolution, long-term evolution system), the uplink control signaling that needs to be transmitted includes ACK / NACK (Acknowledgment / Negative Acknowledgment, correct / error response message), and CSI information (Channel StateInformation , channel state information). Wherein, the CSI fork includes CQI (Channels quality indication, channel quality indication), PMI (Pre-coding Matrix Indicator, pre-coding matrix indication), and RI (Rank Indicator, rank indication). [0003] In the LTE system, the ACK / NACK response message is transmitted on the PUCCH (Physical Uplink Control, Physical Uplink Control Channel) in the format 1 / 1a / 1b (PUCCH format1 / 1a1 / b), if the UE (User Equipment, user equipment) needs to send When uplink data is transmitted on PUSCH (P...
