摘要： Communication systems may benefit from a control channel for contention based transmission and collision avoidance. For example, communication systems of the third generation partnership project (3GPP) long term evolution (LTE) and LTE-Advanced may use such control channels for contention based transmission. In particular, such control channels may be valuable with respect to LTE-based local area network (LTE-LAN). A method, according to certain embodiments, may include preparing control information for a contention based physical uplink shared channel. The method may also include transmitting and/or receiving the control information on a physical uplink control channel and a control only physical uplink shared channel, or only on the control only physical uplink shared channel.
