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. Contention based data transmission in uplink is enabled without previous scheduling request and scheduling grant.

1. A method implemented by a control device of a radio network for allocating resource blocks to user equipments that are configured to transmit data using those resource blocks, the method comprising:
allocating one or more resource blocks to user equipments for the user equipments to transmit a preamble associated with transmission of said data to the control device, wherein the one or more resource blocks allocated for transmission of a preamble are different from a physical random access channel; allocating one or more resource blocks either to a single one of the user equipments for contention free transmission of said data or to multiple ones of the user equipments for contention based transmission of said data, wherein at least one of the resource blocks that is not allocated for contention free transmission is allocated to a first plurality of the user equipments for contention based transmission; and signaling the allocations to the user equipments.
