Abstract: A Small Cell Network in which a terminal is simultaneously served by a macro cell and one or more small cells. These may operate at different frequencies, and may have different bandwidths, traffic loading and support different QoS (Quality of Service). The terminal indicates its preference of cell to employ for its uplink data transmission by sending a scheduling request using a cell selected from a set of cells by the mobile terminal, depending on the UL channel characteristics for the cells in the set and/or on other criteria.

Abstract: A method for activation of a wireless communications link between a terminal (UE) and a first base station (SCeNB) under control of a second base station (MeNB), the method includes: the second base station (MeNB) sending a first activation request signal to the terminal (UE); and the terminal (UE), in response to the first activation request signal, sending a second activation request signal to the first base station (SCeNB). The terminal therefore acts as proxy for communicating an activation request from the second base station to the first base station. This is useful in Small Cell scenarios where backhaul latency may delay an activation request over the X2 interface between the base stations.

Abstract: A scheme to identify the uplink border between two neighboring cells (10, 20) in an LTE-based heterogeneous network, especially one Macro cell (10) and another Small Cell (20). A trigger event is configured for a connected mode UE (1) such that the UE is triggered to send the measurement report about the neighboring cell (20) when the condition “neighbor is offset better than Pcell on UL” is fulfilled. Such a measurement report can be used by the current serving eNB (11) to decide whether one or more neighboring cells (20) should be activated or handed-over to, and/or whether certain information should be sent to one or more neighboring eNBs (21) so that they can start monitoring the uplink connection quality of the UE. In particular it is possible to offload at least part of the UE's uplink traffic from the serving cell (10) to a neighbor cell (20).

Abstract: A buffer status reporting scheme for a terminal (10) wishing to transmit data simultaneously in multiple RATs of a wireless communication network, which enables the co-ordination of multiple base stations (12, 14) of different RATs (e.g. LTE eNB, UMTS base station, WiFi access point, etc.) with the assistance of the terminal (10) in order to achieve efficient radio resource scheduling for multi-RAT multi-flow aggregation in uplink. A radio bearer is configured for multi-RAT multi-flow aggregation by the network, and multiple logical channel IDs are assigned to this RB that may be associated with different RATs. Logical channels associated with a certain RAT (or a given set of RATs) may be grouped into one logical channel group for radio resource scheduling reason. The terminal (10) performs buffer status reporting, according to the configuration, on all involved RATs and sends reports/indications to one or more involved base stations (12.14).

At the network side, multi-RAT flows (RB11) share the same PDCP Entity, (PDCP Entity) while each has independent RLC/MAC (RAT1 RLC Entity, RAT2 RLC Entity). The terminal (UE1) performs necessary measurements on all involved RATs, depending on the requirements of different RATs, and sends measurement reports/indication to all involved base stations. Based on the measurement report as well as pre-defined rules/policy, a decision is made on which RAT should be used for next DL transmission or next period of DL transmission.

Abstract: A method to provide mobility support of UEs (12) that are served by mobile relay base stations (14), by providing handover of a UE (12) for data traffic only between two mobile relay base stations. This is achieved by information exchanging between the source and target mobile relay stations of the concerned UE in handover, and/or the corresponding donor base stations (13, 11) if applicable. The handover is triggered by any of the following: based on UE's measurement report, the signal quality of a neighbour cell is better than the current serving cell; based on the measurement of the serving mobile relay base station, the signal quality of the link to the UE is worse than a certain threshold; or based on the measurement of the serving mobile relay base station, the signal quality of a neighbour cell (potential donor base station) is much better than the current donor base station.
