Abstract: A method in a mobile station for enabling the composing of a set of a cells within a coverage area of a radio access network within which the same information is transmitted time synchronously using a modulation and coding scheme common for the cells of the set. The method includes: identifying one or more pilot signals from respective one or more cells monitored by the mobile station; determining signal and interference levels from the one or more monitored cells if a signal would be transmitted time synchronously using a common modulation and coding scheme within cells of a candidate set of cells; determining one or more modulation and coding schemes selectable with regard to the determined signal and interference levels and the candidate set of cells; and, indicating the one or more determined selectable modulation and coding schemes towards a network node performing the composition of the set of cells.

Abstract: The present invention relates to a UE, base station network node and methods thereof in a cellular mobile communication system. One method concerns handover from a first radio base station to a second radio base station wherein, it comprises the steps receiving a notification from the first radio base station that currently serves said UE, said notification indicating the last packet to be transmitted to this user equipment from said first radio base station on a first connection; and informing the second radio base station by a request to commence transmission from this second radio base station when the notified last packet is received at the UE.

Abstract: A method in a user equipment (UE) includes transmitting, to a first radio base station, one or more protocol data units (PDUs) that are each associated with a respective Internet Protocol (IP) packet. The method also includes receiving one or more feedback indications from the first radio base station, each indicating whether a corresponding PDU was successfully received, and transmitting a retransmission of at least one PDU based on the feedback indications. Additionally, the method includes determining a time point for performing a cell change based on whether the first radio base station has not successfully received all of the PDUs associated with IP packets for which a complete IP packet has been transmitted and performing the cell change at the determined time point.

The proposed method comprises the following steps performed by a mobile station connectable to the radio access network: identifying one or more pilot signals from respective one or more cells monitored by the mobile station, determining signal and interference contributions from the one or more monitored cells with regard to a particular set of cells, reporting the determined signal and interference contributions towards a network node performing the composition of the set of cells.

Abstract: In a radio or wireless access network, packets to be transmitted to a mobile radio are broadcast over a transport network to a set of associated radio access points, where each set of associated radio access points corresponds to a broadcast group. Each access point monitors packets broadcast to it broadcast group to determine if the access point should retrieve the packet. Rather than establishing packet tunnels to specific access points to transport packets to be transmitted to a mobile station through a transport network, those packets simply are broadcast over the transport network to the relevant broadcast group(s). Select diversity may be used where the mobile selects which access point transmits a particular packet to the mobile station. Alternatively, the network may decide which access point transmits a particular packet to the mobile station. This approach greatly facilitates cost-efficient and fast handovers of a mobile connection between access points in a wireless network.

Abstract: Select diversity in cellular radio communications involving both the radio access network and the mobile radio ensures that an optimal base station cell under a current condition is selected for communicating with the mobile radio. A candidate set of radio base station cells is defined for a radio connection between the radio network and the mobile radio. Packets are sent via the radio network to each of multiple radio base stations having a cell in the candidate set. The mobile radio detects a current quality of communication for the radio connection, and based on that detected quality, the candidate cell set may change. The mobile radio selects one of the cells in the candidate cell set to send a next or specific data packet based on one or more selection criteria.
