METHODS AND APPARATUS FOR CONTENTION BASED TRANSMISSION

摘要

Systems and techniques for contention based transmission in a cellular network. A physical uplink shared channel is used for contention based transmission by a device such as a user equipment, based at least in part on information provided by a physical uplink control channel associated with the physical uplink shared channel. In addition, a base station such as an eNodeB may respond to a physical uplink shared channel by providing a common physical downlink shared channel providing acknowledge ment/negative acknowledgement information. In addition, the base station may provide a physical downlink control channel indicating the common physical downlink shared channel.
