Abstract: Updating an uplink contention window size in a listen before talk process in a wireless communication system such as LTE may be done by the eNB if transport blocks contained in the starting subframe of a reference scheduled burst transmitted by a User Equipment are successfully decoded at the eNB. Otherwise, the User equipment adjusts the contention window size depending on information supplied by the eNB. This information identifies the first subframe in the burst whose transport block the base station was able to successfully decode. Depending on whether the User Equipment was first transmitting before or on the identified subframe, the User Equipment can either increase or reset the contention window size.

Abstract: A method for configuring downlink multi-user transmission in a telecommunication network is provided. The method comprises receiving, at a first User Equipment (UE), data within a subframe wherein the data comprises a dynamic indicator; determining, by the first UE based on the received dynamic indicator, if the data within the subframe is for multi-user transmission, and if not so determined, using, by the first UE, a single-user receiver to decode the received data; and if so determined, identifying, by the first UE based on the dynamic indicator, at least one second UE that is paired with the first UE in multi-user transmission, and obtaining, by the first UE DCI information of said at least one second UE.
