Apparatus, communication system and methods for enabling spectrum access
First Claim
1. A method for enabling spectrum access in a wireless communication system that supports simultaneously at least a first mode of operation and a second mode of operation, wherein the method comprises:
- determining a proportion of spectrum required for the wireless communication unit to operate simultaneously in both the first mode of operation and the second mode of operation; and
enabling spectrum access in a wireless communication system by allocating a temporary guard band between a first portion of spectrum for the wireless communication unit to operate in the first mode of operation and a second portion of spectrum for the wireless communication unit to operate simultaneously in the second mode of operation, wherein a bandwidth of the temporary guard band is based on a mapping of services to one or more frequency carriers.

Abstract
Embodiments of the invention provide for allocating spectrum in a wireless communication system that supports simultaneously at least a first mode of operation and a second mode of operation. Logic is arranged for determining a proportion of spectrum required for the wireless communication unit to operate simultaneously in both the first mode of operation and the second mode of operation. Logic for allocating spectrum allocates a temporary guard band between a first portion of spectrum for the first mode of operation and a second portion of spectrum for the second mode of operation for use while the wireless communication unit operates simultaneously in the first mode of operation and second mode of operation.

24. A wireless communication unit capable of a simultaneous dual mode operation for simultaneously communicating in at least a first mode of operation and a second mode of operation, wherein the wireless communication unit comprises:
-
a transceiver capable of transmitting and receiving simultaneously in both a first mode of operation in a first portion of spectrum and a second portion of spectrum in a second mode of operation; and logic for adapting a frequency of operation of the transceiver to accommodate an allocated temporary guard band between the first portion of spectrum and second portion of spectrum for a duration of a simultaneous dual mode operation of the wireless communication unit. - View Dependent Claims (25, 26, 27)

28. A method of simultaneously communicating in at least a first mode of operation and a second mode of operation of a wireless communication system, wherein the method comprises:
-
transmitting and receiving simultaneously in both a first mode of operation in a first portion of spectrum and in a second mode of operation in a second portion of spectrum; and adapting a frequency of operation of transmitting and receiving simultaneously in a first portion of spectrum and second portion of spectrum to accommodate an allocated temporary guard band between the first portion of spectrum and second portion of spectrum, wherein the temporary guard band is dynamically allocated in response to a request for simultaneous dual-mode operation and for a duration of the simultaneous dual-mode operation.
