Abstract: Transfer of Multimedia Broadcast/Multicast Services (MBMS) over a Single Frequency Network (MBSFN) service and idle mode unicast service for a mobile entity from a source base station to a target base station may be managed by a base station or mobile entity of a cellular wireless communications system (WCS). Operations related to the transfer may include obtaining an MBMS status of the mobile entity, and/or obtaining MBMS support information for the base station. A network entity may facilitate MBMS discovery by a mobile entity, by transmitting a data element to the mobile entity including service identifiers mapped to corresponding cell identifiers to indicate respective MBMS services to be broadcast in an WCS area on adjacent cells identified by respective ones of the cell identifiers. The MBMS services may be broadcast within the WCS area using the adjacent cells previously indicated in the data element.

Abstract: A coax line terminal (CLT) transmits allocations of upstream bandwidth to a plurality of coax network units (CNUs). In response to the allocations, the CLT receives frames with data in a plurality of physical resource blocks that each correspond to a distinct set of subcarriers. The plurality of physical resource blocks includes a first group of physical resource blocks that all have a first constant allowed capacity. Sizes and modulation orders of respective physical resource blocks in the first group vary as defined by a first modulation profile. The data in the first group are received from one or more CNUs that are assigned the first modulation profile.

Abstract: Techniques are provided to facilitate offloading of mobile entities from a serving network entity. For example, there is provided a location-based method that involves, in response to a load of the requesting entity exceeding a load threshold, identifying candidate network entities to which to offload a user equipment (UE), each of the candidate network entities being in sleep mode. The method may involve determining coverage and location information for the candidate network entities, and determining location information for the UE. The method may involve selecting a given network entity to turn ON based at least in part on the coverage information and the location information. The method may involve sending an ON-request message to the at least one selected network entity, the ON-request message including a timer that can be used to deactivate the selected network entity in case it is not useful in offloading the serving network entity.

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.
