Embodiment Construction

[0068] In the following, certain exemplary embodiments are explained with reference to a wireless or mobile communication system serving mobile communication devices. Before explaining the exemplary embodiments in detail, refer to Figures 1 to 3 Some general principles of wireless communication systems, their access systems, and mobile communication devices are briefly explained to aid in understanding the technology underlying the described examples.

[0069] An example of a wireless communication system is the architecture standardized by the 3rd Generation Partnership Project (3GPP). The latest 3GPP-based development is often referred to as the long-term evolution (LTE) of the Universal Mobile Telecommunications System (UMTS) radio access technology. The various stages of development of 3GPP LTE specifications are called releases. A more recent development of LTE is often referred to as LTE-Advanced (LTE-A). LTE employs a mobile architecture known as the Evolved Univers...

Abstract

A method, comprising: determining a codebook size using first information and second information, the first information including information for at least one first subframe of at least one cell for which feedback information is to be provided, the at least A first subframe is before subframe n, and the second information is for at least one second subframe of at least one cell for which feedback information is to be provided, and the at least one second subframe is after the subframe n; and using the codebook size for providing feedback information.

Description

technical field [0001] The present disclosure relates to methods and apparatus and particularly but not exclusively to methods and apparatus for use with time division duplex carrier aggregation. Background technique [0002] A communication system may be seen as a facility enabling a communication session between two or more nodes such as fixed or mobile equipment, machine type terminals, access points such as base stations, servers and the like. Communication systems and compatible communicating entities typically operate in accordance with given standards or specifications that set out what the various entities associated with the system are permitted to do and how this should be accomplished. For example, standards, specifications, and related protocols may define how devices should communicate, how aspects of communication should be implemented, and how devices should be configured for use in a system. [0003] Users can access the communication system by means of appr...
