Claim of US Patent No. 10,117,275

1. A method implemented by a long term evolution (LTE) wireless transmit receive unit (WTRU) accessing a contention-based (CB) shared channel, and accessing a contention-free shared channel allocated by receiving an uplink grant for the WTRU from a base station, the method characterized by:receiving radio resource control (RRC) signaling, indicating resources for the CB shared channel;
wherein the CB shared channel is selected autonomously by the WTRU from the resources indicated in the RRC signaling; and
on a condition that an uplink grant is received in a random access response for a subframe in which a transmission using the CB shared channel would occur, not transmitting using the CB shared channel in the subframe and transmitting using the contention-free shared channel using the uplink grant received in the random access response.
