A base station adapted to share resources of a communication bandwidth between a plurality of network operators (4-A, 4-B, 4-C), the base station comprising: means for defining: (a) a first proportion of said resources of said communication bandwidth, said first proportion representing a first virtual pool of resources; (b) a second proportion of said resources of said communication bandwidth, said second proportion representing a second virtual pool of resources; (c) for said first virtual resource pool: a respective first pool proportion, for each network operator, representing a reserved proportion of the resources of the first virtual pool to be allocated for a set of one or more communication bearers for that network operator; and (d) for said second virtual resource pool: a respective second pool proportion, for each network operator, representing a reserved proportion of the resources of the second virtual pool to be allocated for the set of one or more communication bearers for that network operator; means for prioritising allocation of resources to the respective set of one or more communication bearers for each network operator in dependence on an analysis based on the pool proportion of that network operator in at least one of said virtual resource pools; and means for allocating resources, in a current scheduling round, to the communication bearers of each network operator in dependence on a scheduling priority attributed to the communication bearers of that network operator by the prioritising means. means for defining: (a) a first proportion of said resources of said communication bandwidth, said first proportion representing a first virtual pool of resources; (b) a second proportion of said resources of said communication bandwidth, said second proportion representing a second virtual pool of resources; (c) for said first virtual resource pool: a respective first pool proportion, for each network operator, representing a reserved proportion of the resources of the first virtual pool to be allocated for a set of one or more communication bearers for that network operator; and (d) for said second virtual resource pool: a respective second pool proportion, for each network operator, representing a reserved proportion of the resources of the second virtual pool to be allocated for the set of one or more communication bearers for that network operator; (a) a first proportion of said resources of said communication bandwidth, said first proportion representing a first virtual pool of resources; (b) a second proportion of said resources of said communication bandwidth, said second proportion representing a second virtual pool of resources; (c) for said first virtual resource pool: a respective first pool proportion, for each network operator, representing a reserved proportion of the resources of the first virtual pool to be allocated for a set of one or more communication bearers for that network operator; and a respective first pool proportion, for each network operator, representing a reserved proportion of the resources of the first virtual pool to be allocated for a set of one or more communication bearers for that network operator; and (d) for said second virtual resource pool: a respective second pool proportion, for each network operator, representing a reserved proportion of the resources of the second virtual pool to be allocated for the set of one or more communication bearers for that network operator; a respective second pool proportion, for each network operator, representing a reserved proportion of the resources of the second virtual pool to be allocated for the set of one or more communication bearers for that network operator; means for prioritising allocation of resources to the respective set of one or more communication bearers for each network operator in dependence on an analysis based on the pool proportion of that network operator in at least one of said virtual resource pools; and means for allocating resources, in a current scheduling round, to the communication bearers of each network operator in dependence on a scheduling priority attributed to the communication bearers of that network operator by the prioritising means.
