Scheduling Requests in Small Cell Networks
First Claim
1. A wireless communication method in which a terminal communicates with a network via a plurality of cells which simultaneously serve the terminal, wherein the terminal indicates to the network at least one preferred cell for its uplink data transmission by selecting at least one cell for transmission of an uplink data transmission request from among the plurality of said cells.

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.
