Transmission Method and Devices in a Communication System with Contention-Based Data Transmission

摘要

A method is described for data transmission by user equipments adapted to transmit data using resource blocks allocated by a radio network. The radio network is adapted to allocate resource blocks to a dedicated one of the user equipments or to a plurality of the user equipments. The method comprises the step of allocating at least one of the resource blocks that is not allocated to any dedicated user equipment to a first plurality of the user equipments. The allocation is signaled to the user equipments. A first user equipment of said first plurality obtains data for transmission. At least a first part of the data is transmitted by the first user equipment using said at least one resource block. Devices embodying the invention and methods of operating the devices are also described.

1. A method implemented by a control device of a radio network for allocating resource blocks to communication devices configured to transmit data to the radio network using the allocated resource blocks, the method comprising:
allocating at least one resource block not allocated to any dedicated communication device to a first plurality of communication devices; signaling the allocation to the first plurality of communication devices; receiving data transmitted by a first communication device of the first plurality of communication devices using the at least one allocated resource blocks, the received data including a reference signal; and detecting, based on the reference signal, at least one of a modulation and coding scheme (MCS) of the received data and a collision of the received data with data transmitted by one or more additional communication devices.
