Title:
METHOD AND APPARATUS FOR TRANSMITTING UPLINK CONTROL SIGNALING ON PHYSICAL UPLINK SHARED CHANNEL
Document Type and Number:
WIPO Patent Application WO/2010/145588
Kind Code:
A1
Abstract:
The present invention discloses a method for transmitting uplink control signaling on a Physical Uplink Shared Channel (PUSCH). The method includes: when two transport blocks/codeword streams are transmitted on a PUSCH, mapping uplink control signaling onto the layers corresponding to one of the two transport blocks/codeword streams to transmit. The present invention also discloses an apparatus for transmitting uplink control signaling on a PUSCH. The apparatus includes: a mapping unit, used for mapping uplink control signaling onto the layers corresponding to one of two transport blocks/codeword streams when the two transport blocks/codeword streams are transmitted on a PUSCH, and a transmission unit, used for transmitting the uplink control signaling. The present invention effectively solves the problem of transmitting uplink control signaling on a PUSCH when space division multiplexing is adopted on the PUSCH in an LTE-A system, and guarantees the data capacity. The channel quality corresponding to the transport blocks selected in various ways is relatively good, therefore guaranteeing the transmission quality of uplink control signaling.
