Abstract: Methods, systems, and devices are described for mobility robustness optimization. A network may be organized into base station clusters, and mobility information may be exchanged within the cluster. Each base station may then receive statistics based on the collected information. In some examples the cluster mobility statistics are used to generate a handover transition matrix identifying a probability of a UE remaining with a target base station within the cluster for a threshold period following a handover from a source base station that is also within the cluster. Based on the cluster mobility statistics, the base station may determine that the probability of the UE remaining with the potential target base station for the threshold period is low. The base station may then select an alternative handover target. The base station may then adjust the mobility parameters of the UE in order to direct it to the alternative handover target.

Abstract: In one or more access points of a wireless communication network, a method for participating in a distributed clustering process directed at defining clusters of access points wherein each of the clusters comprises a cluster head and associated member nodes includes determining a marginal cost of associating an access point to each of distinct clusters of access points, based on a defined cost function, and associating the access point to one of the clusters of APs for which the marginal cost is minimized. The method may be performed by multiple access points in a peer-to-peer fashion and iterated until a stable cluster configuration is obtained. A cluster head may similarly be appointed in a distributed fashion by a current cluster head comparing total cost functions between different cluster configurations with different cluster heads.

Abstract: Apparatus, methods, and computer program products providing power savings in Semi-Persistent Scheduling (SPS)-configured Voice over Long Term Evolution (VoLTE) with Connected State Discontinuous Reception (C-DRX) are provided. The apparatus may be a user equipment (UE). The UE receives a packet when the UE is in a persistent scheduling mode. The UE transmits a negative-acknowledgement (NACK) message when the packet is not successfully decoded. The UE refrains from transmitting an acknowledgement (ACK) message when the packet is successfully decoded. The UE may enter a power save state immediately after the packet is successfully decoded. The packet may be addressed to the UE in a unicast message. The packet may be received during an on-duration of a C-DRX cycle. The packet my include VoLTE downlink (DL) traffic. The packet may be received on a physical downlink shared channel (PDSCH).

Abstract: Methods in a multiple-cell cellular network that implements iterative coordinated beamforming (I-CBF) algorithms with limited cooperation from adjacent nodes (base stations and/or mobile stations) may jointly determine transmit beamforming vectors and receive combining vectors to increase sum throughput. The transmit beamforming vectors and receive combining vectors can be determined based on a performance metric, such as by maximizing SINR (signal-to-interference-and-noise ratio) for each mobile station in the network, maximizing SLNR (signal-to-leakage-and-noise ratio) for each base station in the network, or minimizing SMSE (sum mean square error). The algorithms may be performed to update vectors synchronously. In other cases, the algorithms may be performed to update vectors asynchronously.
