HARQ-ACK Channel Resource Allocation for LTE-A Transmit Diversity

The patent segments the PUCCH resource allocation into two distinct parts: one for non-transmit diversity channels and another for transmit diversity channels. This segmentation allows independent optimization of resource allocation for each type, preventing resource waste while maintaining support for both channel selection and transmit diversity modes simultaneously.

The patent introduces a new dimension to PUCCH resource allocation by defining resource allocation in the frequency domain using PUCCH resource indicators (PRIs). This dimensional change enables more flexible and efficient resource assignment, allowing the system to support transmit diversity without proportionally increasing overall resource consumption.

The patent applies local quality by allocating PUCCH resources specifically for transmit diversity channels based on the actual transmit diversity configuration of each cell. Resources are allocated locally and independently for each cell's transmit diversity requirements, ensuring that resources are neither over-provisioned nor under-provisioned, thus optimizing resource utilization while maintaining reliability.

The patent changes the allocation parameters by using cell-specific configurations and PUCCH resource indicators to dynamically adjust the number and location of PUCCH resources allocated for transmit diversity. This parameter-based approach allows the system to adapt resource allocation to actual network conditions and cell configurations, improving both reliability and resource utilization.
