FIELD: radio engineering, communication.
SUBSTANCE: device conducting uplink MIMO communication in a wireless communication system can multiplex control signalling and data across one or more of a plurality of layers (e.g., corresponding to spatial layers, codewords, etc.) associated with an uplink transmission. Techniques are described herein for selecting layers of a transmission on which to schedule control signalling and selecting offsets to apply to the control signalling scheduled on selected layers. Further, techniques are described herein for leveraging a multi-layer transmission to increase efficiency of acknowledgement communication. In addition, techniques are described for selecting a modulation and coding scheme (MCS) to apply to control signalling that is combined with data in an uplink multi-layer transmission.
EFFECT: easier multiplexing of control information and data for uplink MIMO transmission in a wireless communication system.
