Method and apparatus for transmitting uplink control signaling on physical uplink shared channel

摘要

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.

1. A method for transmitting uplink control signaling in a physical uplink shared channel (PUSCH), comprising:
when two transport blocks/codewords are transmitted in a PUSCH, selecting a transport block/codeword with a larger index of modulation and coding scheme indexes of the two transport blocks/codewords in the PUSCH to carry the uplink control signaling, and mapping the uplink control signaling to a layer/layers corresponding to the selected transport block/codeword to transmit; wherein said modulation and coding scheme indexes of the transport blocks/codewords in the PUSCH are determined by a base station according to a modulation and coding scheme selected by the base station, and notified to a user equipment by the base station.
