Abstract
A method and apparatus for allocating quasi-contiguous uplink data resources for a user device is provided. Transmission of data comprise at least two data clusters of sub carriers expanding over gaps reserved for uplink control channel in order, for example, to mitigate transmission power reductions due to multi-cluster transmission.
Claims18
A method comprising:
- receiving an allocation of uplink data resources comprising clusters of sub carriers expanding over at least one gap of resource blocks for the user device from a base station;
- determining whether the allocation is quasi-contiguous;
- applying, in dependence of the determination of whether the allocation is determined to be quasi-contiguous, a maximum power reduction to a transmission in the allocated uplink data resources;
- wherein the determining whether the allocation is quasi-contiguous is based on at least one of:
- a determination that the at least one resource block gap in the allocation is filled with an uplink control channel allocation;
- a determination that a size of the at least one resource block gap in the allocation does not exceed a specified maximum;
- and
- a determination that the base station has signaled the allocation to be quasi-contiguous.
5 more elements
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code,
- wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus at least to:
- receive an allocation of uplink data resources comprising clusters of sub carriers expanding over at least one gap of resource blocks from a base station;
- determine whether the allocation is quasi-contiguous;
- apply, in dependence of the determination of whether the allocation is determined to be quasi-contiguous, a maximum power reduction to a transmission in the allocated uplink data resources;
- wherein the determining whether the allocation is quasi-contiguous is based on at least one of:
- a determination that the at least one resource block gap in the allocation is filled with an uplink control channel allocation;
- a determination that a size of the at least one resource block gap in the allocation does not exceed a specified maximum;
- and
- a determination that the base station has signaled the allocation to be quasi-contiguous.
9 more elements
A computer program, embodied on a non-transitory computer readable medium, wherein the computer program is configured to control an apparatus to perform a process, comprising:
- receiving an allocation of uplink data resources comprising clusters of sub carriers expanding over at least one gap of resource blocks from a base station;
- determining whether the allocation is quasi-contiguous;
- applying, in dependence of the determination of whether the allocation is determined to be quasi-contiguous, a maximum power reduction to a transmission in the allocated uplink data resources;
- wherein the determining whether the allocation is quasi-contiguous is based on at least one of:
- a determination that the at least one resource block gap in the allocation is filled with an uplink control channel allocation;
- a determination that a size of the at least one resource block gap in the allocation does not exceed a specified maximum;
- and
- a determination that the base station has signaled the allocation to be quasi-contiguous.
