A method includes selecting a subset k of N accessible antennas to use to process a transmission received at the N antennas and sent by a user equipment, and processing the transmission from the user equipment at least by using baseband information from the k antennas. An apparatus includes one or more processors and one or more memories including computer program code. The one or more memories and the computer program code are configured to, with the one or more processors, cause the apparatus to perform at least the following: selecting a subset k of N accessible antennas to use to process a transmission received at the N antennas and sent by a user equipment; and processing the transmission from the user equipment at least by using baseband information from the k antennas. Additional apparatus, computer programs, and computer program products are disclosed.

Uplink grouping and aperture apparatus

A method is disclosed that includes accessing baseband information for a number, N (N&#x3e;1), of antennas accessible by a number of baseband units, where the baseband information correspond to a transmission by a user equipment and is received at the N antennas. The method includes determining values for one or more metrics for the baseband information for the N antennas. The method includes selecting, based on the determined values, a subset k of the N antennas and corresponding baseband information to use to determine output data for the transmission by the user equipment. The method includes determining the output data for the user equipment using the baseband information from the k antennas. Apparatus and computer program products are also disclosed.

Cell clustering and aperture selection

Systems and techniques for managing interference between pico cells in a pico cluster. Pico eNodeBs are configured in groups for each of a plurality of UEs, based on factors such as signal to noise ratio and geographic location. All signals from UEs may be measured by all eNodeBs in the cluster, but a pico group decodes packets only of UEs associated with the pico group. Decoded packets are exchanged between pico groups, and when a pico group is unable to decode packets of an associated UE, is uses the decoded packets received in exchanges to reconstruct an interference signal. The interference signal is subtracted from the received signal and the resulting received signal is used to decode the packets of the UE.

Methods and apparatus for interference management

An apparatus and method that optimizes the data rate for forward link data transmissions in a spread-spectrum communications systemis provided. The spread-spectrum communications systemcomprises a wireless infrastructure, at least one wireless mobile receiving device, and an radio frequency (RF) forward linkbetween the wireless infrastructureand the wireless mobile receiving device. The data rate of the RF forward linkis optimized in the wireless infrastructureby estimating or measuring the bottleneck link speed of the data transmission and adjusting the data rate for the RE forward linkaccording to several embodiments of a data rate optimization algorithm. The algorithm creates an optimum range for the data rate of the RF wireless linkwhich maximizes system capacity and reduces transmission delays to the wireless mobile receiving device
