Abstract:
1. A method, in a network node, for determining at least one timing configuration number to use for configuring the timing of control signalling across a plurality of aggregated cells of a multiple cell communications network, each aggregated cell being associated with an uplink-downlink configuration number that indexes an uplink-downlink configuration defining uplink and downlink resources for that cell, wherein at least two uplink-downlink configuration numbers of the plurality of aggregated cells are not equal, and said plurality of aggregated cells being associated with a user equipment, the method comprising: analysing at least two ordered sets of timing configuration numbers, wherein different timing configuration numbers index different control timing configurations that configure the timing of control signalling differently for different uplink-downlink configurations, wherein each ordered set corresponds to a respective cell associated with the user equipment in the multiple cell communications network and includes timing configuration numbers ordered based on how compatible the corresponding control timing configurations are with the uplink-downlink configuration of that respective cell; and assigning, for configuring the timing of control signalling across the plurality of aggregated cells, at least one timing configuration number from said at least two ordered sets of timing configuration numbers.
