Abstract:

The disclosure provides methods and apparatus relating to the transmission of control information in uplink access of wireless networks. One embodiment provides a method performed by a wireless device operable in a wireless communications network. The method comprises: responsive to failure of transmission in a first transmission time interval of a first transport block comprising first control information, transmitting in a second, subsequent transmission time interval a second transport block comprising second control information, wherein the second control information is an updated version of the first control information. Failure of transmission of the first transport block comprises the wireless device determining that a wireless channel over which the first transport block is to be transmitted is busy in the first transmission time interval.
