Uplink resource allocation for LTE advanced

摘要

Methods, systems, apparatus and computer program products are provided to receive downlink control information (DCI) in a downlink control channel, where the downlink control information configured to indicate an allocation of uplink resources with a clustered uplink resource allocation protocol or a contiguous uplink resource allocation protocol, to detect which of the clustered uplink resource allocation protocol and the contiguous uplink resource allocation protocol is indicated and to allocate the uplink resources based on the indicated uplink resource allocation protocol.

1. A method in a wireless communication device, comprising:
receiving downlink control information (DCI) in a downlink control channel, the DCI configured to indicate an allocation of uplink resources with a clustered uplink resource allocation protocol or a contiguous uplink resource allocation protocol; detecting which of the clustered uplink resource allocation protocol and the contiguous uplink resource allocation protocol is indicated based on the DCI, wherein the clustered uplink resource allocation protocol comprises an allocation of two or more clusters with an allocation resolution of one resource block group, wherein each resource block group's size depends on a system bandwidth; and communicating using the uplink resources based on the indicated uplink resource allocation protocol.
