CONTENTION-BASED PHYSICAL UPLINK SHARED CHANNEL
First Claim
1. A method of wireless communication comprising:
- identifying uplink (UL) control information (UCI) to transmit during a subframe;
identifying a scheduling type for a UL data channel during the subframe; and
determining whether to transmit the UCI on the UL data channel based at least in part on the scheduling type.

Abstract
Methods, systems, and devices for wireless communication are described. A user equipment (UE) may identify uplink (UL) control information (UCI) to transmit during a subframe. The UE may then select a UL channel on which to transmit the UCI based on whether a shared data and control UL channel employs contention-based scheduling. For example, multiple UEs could contend for access to the same semi-persistently scheduled (SPS) physical UL shared channel (PUSCH). Each UE may utilize a different demodulation reference (DMRS) signal cyclic shift to identify their transmissions. In some cases, some UCI, such as channel state information (CSI), may be transmitted on a contention-based PUSCH, while other UCI, such as acknowledgement information, may be transmitted on a physical uplink control channel (PUCCH). In some cases, the channel selection may be based on a configuration received from a base station.

18. A method of wireless communication comprising:
-
transmitting a control message to a user equipment (UE) that indicates an uplink (UL) control information (UCI) handling configuration; identifying a scheduling type for a UL data channel during a subframe; and receiving UCI from the UE, wherein the UCI is transmitted based at least in part on the UCI handling configuration and the scheduling type. - View Dependent Claims (19, 20, 21)

22. An apparatus for wireless communication, comprising:
-
a processor; memory in electronic communication with the processor; and instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to; identify uplink (UL) control information (UCI) to transmit during a subframe; identify a scheduling type for a UL data channel during the subframe; and determine whether to transmit the UCI on the UL data channel based at least in part on the scheduling type. - View Dependent Claims (23, 24, 25, 26)
