Embodiment Construction

[0033] Certain terms are used throughout the description and claims to refer to particular components. Those skilled in the art should understand that manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. "Include" and "comprising" mentioned in the entire specification and claims are open terms, so they should be interpreted as "including but not limited to". Otherwise, the term "coupled" includes any direct and indirect means of electrical connection. Indirect means of electrical connection include connection through other means.

[0034] Some embodiments of the present invention are described below with reference to the accompanying drawings.

Abstract

HARQ feedback channel design for carrier aggregation (CA) is proposed in a multi-carrier LTE / LTE-A system. In one novel aspect, a predefined rule for HARQ feedback channel format switching is adopted by the system. Different HARQ formats are supported: single component carrier (non-CA) mode, carrier aggregation with small payload size (CA-S) mode, carrier aggregation with large payload size (CA-L) mode, and fallback mode. From the various CA and non-CA formats, the format to be used for uplink HARQ feedback channel is determined based on: UE capability for the maximum number of CCs supported; CC configuration information by RRC layer; and detection results of downlink schedulers. The CC configuration information may include the number of CCs that are configured and a specific HARQ format to be used. Because more reliable upper layer configuration is used to make the HARQ format- switching decision, the risk of UE and eNB mismatch is greatly reduced.
