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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Contention-based physical uplink shared channel","description":"Methods, systems, and devices for wireless communication are described.
