Abstract
Official abstract text for this publication.
A method, NodeB and User Equipment for TDD operation in a communication system operating in TDD mode in a frequency band allocated for FDD operation. Preferably, operation is in TDD uplink and downlink mode in a first frequency band designated or normally used for FDD uplink communication, and in TDD downlink-only mode in a second frequency band designated or normally used for FDD downlink communication. The invention provides the following advantages: Provides a flexible method to deploy a time division duplex architecture in frequency division duplex spectrum. Allows flexible use of system capacity by adjusting the uplink and downlink capacity split. Removes previous FDD duplex restrictions.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for communicating by an electronic device, the method comprising: performing wireless communications in a first frequency channel with a first frequency carrier device; performing wireless communications in a second frequency channel with an additional frequency carrier device; exchanging a capability message with a base station to inform the base station that the electronic device is able to utilize both the first frequency channel and th…
