In one configuration, the apparatus receives at least one of UE count information or signal quality information from each of at least one base station. The UE count information includes a number of UEs that are interested in receiving MBMS services. The signal quality information includes MBSFN measurement information. The apparatus determines whether a base station should be part of a multicast broadcast service area based on the at least one of the UE count information or the signal quality information. The multicast broadcast service area may include one or more of an MBMS service area, an MBSFN area, an MTCH SFN, or an MCCH SFN. The apparatus sends to the base station information indicating whether the base station should be part of the multicast broadcast service area.

Abstract: Methods and apparatus for performing dynamic channel selection are provided. In an example, a method includes receiving, at a central self-organizing network server, data from an access point (AP) including a number of stations associated with the AP. The method includes calculating downlink capacities for the associated stations and selecting a channel for the AP which maximizes a pre-defined network utility that is based on the downlink capacities. Further, it is determined if the network utility gain resulting from selecting the channel exceeds a threshold when compared to a previous channel selection state. If the network utility gain exceeds the threshold, a channel change command is issued to the AP, directing the AP to use the selected channel to communicate with a specific station.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a first capability message to a network entity indicating that the UE may be capable of using a subset of antenna ports of a set of antenna ports for uplink sounding on a wireless band. Further, one or more antenna ports of the set of antenna ports may be available for the uplink sounding and the first capability message may include an indication of the set of antenna ports. The UE may then receive control signaling from the network entity indicating the subset of antenna ports that the UE should use for the uplink sounding based on the first capability message. As such, as part of the uplink sounding on the wireless band, the UE may transmit one or more sounding reference signals (SRSs) via the subset of antenna ports indicated by the control signaling.

Abstract: Waveforms for wireless communication are shaped asymmetrically according to a complex-valued weighted overlap/add (WOLA) filter. A wireless communication device generates a waveform corresponding to a carrier. The device determines whether neighboring carriers are being used for wireless communication. If one neighboring carrier is occupied and the other is unoccupied, the wireless communication device applies the asymmetrical filter to the waveform such that out-of-band signals which may interfere with the occupied carrier are suppressed to a greater extent than out-of-band signals potentially present in or around the unoccupied carrier. The wireless communication device then transmits the asymmetrically shaped waveform to maximize interference reduction and signal quality.
