Abstract
A communication device that forms part of a network comprising a plurality of cells, each comprising a communication device configured to communicate with at least one terminal via a frequency hopping sequence associated with its respective cell, the communication device being configured to, responsive to a determination that there are an insufficient number of frequencies available to provide frequency hopping sequences for it and the communication devices in its neighbouring cells that are sufficiently distinct from each other, share the insufficient number of frequencies with of those communication devices on a time division basis.

A communication device that forms part of a network comprising a plurality of cells, each comprising a communication device configured to communicate with at least one terminal via a frequency hopping sequence associated with its respective cell, the communication device being configured to, responsive to a determination that there are an insufficient number of frequencies available to provide frequency hopping sequences for it and the communication devices in its neighbouring cells that are sufficiently distinct from each other, share the insufficient number of frequencies with those communication devices on a time division basis.
(canceled)
A communication device as claimed in claim 67, configured to communicate the downlink portion and the uplink portion of the frame in timeslots arranged such that the time from the start of the timeslot for the downlink portion to the end of the timeslot for the uplink portion is less than or equal to the duration of a frame via which the communication device normally communicates with the at least one terminal.

A communication network comprising:
- a plurality of cells, each comprising a communication device configured to communicate with at least one terminal via a frequency hopping sequence associated with its respective cell;
- each communication device being further configured to, responsive to a determination that there are an insufficient number of frequencies available to provide frequency hopping sequences for it and the communication devices in neighbouring cells that are sufficiently distinct from each other, share the insufficient number of frequencies with those communication devices on a time division basis.

A controller for determining a frequency hopping sequence for a communication device that is configured to communicate with at least one terminal via a frequency hopping sequence associated with its respective cell, the controller being configured to:
- determine that there are an insufficient number of frequencies available to provide frequency hopping sequences for two or more communication devices in neighbouring cells that are sufficiently distinct from each other;
- and
- instruct those two or more communication devices to share the insufficient number of frequencies between them on a time division basis.
