METHODS AND APPARATUS FOR CONTENTION-BASED GRANTING IN WIRELESS COMMUNICATION NETWORK Russian patent published in 2015 - IPC H04W74/00 H04W72/00 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to wireless communication. Associating a plurality of contention-based uplink grants with a range of uplink resource blocks allows one contention-based uplink grant message to signal the entire plurality of grants. The signalling load on the PDCCH is reduced by using a single contention-based uplink grant message to signal a plurality of contention-based uplink grants. The message indicates an allocated set of uplink resource blocks and the number of separate uplink resource grants represented by the set and is signalled such that user terminals recognise that separate subsets of uplink resource blocks within the set correspond to a separate contention-based uplink grant. Information included in the contention-based uplink grant message is used to control the probability at which the user terminals attempt contention-based uplink transmissions and/or to control the modulation and coding scheme used for such transmissions.

EFFECT: reducing the probability of collision with multiple users in a cell.
