A method of configuring transmissions over a radio bearer between a base station and user equipment of a wireless telecommunication network, a base station, user equipment, a radio network controller and computer program products are disclosed. The method of configuring transmissions over a radio bearer between a base station and user equipment of a wireless telecommunication network comprises the steps of: preconfiguring the user equipment to support transmissions over a plurality of transport channels of the radio bearer, the plurality of transport channels being associated with a communication state of the user equipment, each of the plurality of transport channels being mappable with logical channels of the radio bearer, the logical channels providing information to be transmitted by the transport channels; and remapping the logical channels onto a different one of the plurality of transport channels in response to a message transmitted between the base station and the user equipment, the message indicating the different one of the plurality of transport channels to be used to support the transmissions between the base station and the user equipment. This approach enables the user equipment or base station to select a transport channel to carry the information from the logical channels autonomously of other network nodes within the network, such as, for example, the radio network controller. By avoiding the need to involve other network nodes in the reselection of the transport channel, rapid changes in the transport channel can be made based on knowledge of the current conditions within either the base station or the user equipment. This approach enables fast switching of the transport channel to improve the performance of the network.

Configuring transmissions by remapping the logical channels onto different one of the plurality of transport channels

The present disclosure relates to a baseband processing assembly () for processing signals of at least one remote radio head (), the at least one remote radio head () serving a radio cell () of a cellular communication system, the baseband processing assembly () comprising a set of user packet schedulers (A-M) and a cell packet scheduler (), wherein the cell packet scheduler () is assigned to the radio cell (), wherein the set of user packet schedulers (A-M) are assigned to a group of users (A-N) associated to the radio cell (), wherein the cell packet scheduler () and a first user packet scheduler (A-M) of the set of user packet schedulers (A-M) are operable to mutually exchange data for providing resource assignment information and establishing a channel () with a first user (A-N) of the group of users using the resource assignment information.

Scheduling virtualization for mobile cloud for low latency backhaul

A method of controlling uplink transmission on an acquired common channel by user equipment in a wireless communications network. User equipment and a computer program product operable to perform that method. The method comprises: determining a predetermined acquired common channel retention period; requesting allocation of common network resource for an uplink transmission; receiving an indication of an allocated acquired common channel; assessing whether said uplink transmission meets uplink criteria for said allocated acquired common channel and, if said uplink criteria are met, transmitting said uplink transmission on said allocated acquired common channel within said common channel retention period. Aspects allow common channels in a network to be used by user equipment if it is determined that a pending uplink transmission is suitable for transmission on an allocated common channel.

Uplink transmission

A method and system in which a UMTS base station determines if any UE has re-acquired a common Enhanced Dedicated Channel (E-DCH) resource, and responsively transmits a indicator toward an RNC that is adapted to cause the RNC to recognize the beginning of a new transmission session so that the RNC may responsively perform appropriate actions such as flushing the TSN re-ordering queue, restarting a MAC-is re-ordering algorithm and the like.
