Abstract: Systems, methods, apparatuses, and computer-readable storage media for communicating a base station signal, such as a data signal, a control signal, or both, from a base station to a user equipment (UE) during a measurement window. In some aspects, the UE signals its availability corresponding to a measurement window to a serving base station. In some aspects, the UE signals a guard period associated with the measurement window to the serving base station. In other aspects, the serving base station signals a guard period to the UE.

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: 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: A network device includes a plurality of physical-media entities (PMEs), each corresponding to a distinct channel, to generate transmit signals based on transmit packets received over a media-independent interface. The network device also includes a channel-bonding sublayer to direct the transmit packets from the media-independent interface to respective PMEs of the plurality of PMEs. The channel-bonding sublayer has a substantially fixed delay between the media-independent interface and the plurality of PMEs for the transmit packets.

Abstract: Described herein are techniques for link adaptation at an access point enabled for coordinated scheduling. For example, the technique may involve determining a resource-allocation profile (RAP) for the access point, wherein the RAP is based on a set of statistics associated with channel conditions for mobile devices. The technique may involve determining a plurality of link adaptation instances configured for managing interference, each link adaptation instance being associated with an interference condition. The technique may involve for each link adaptation instance, updating the link adaptation instance based on statistics associated with the interference condition.

Abstract: Methods and apparatuses are provided for facilitating dynamic measurement power offset adjustments for use in reporting channel quality feedback. A user equipment may generate and send a plurality of channel quality indicator (CQI) values to a base station. The base station determines whether at least some of the received CQI values are outside of an upper or lower threshold value. If at least some of the received CQI values are outside the upper or lower threshold value, the base station can transmit an adjusted measurement power offset to the user equipment. On receipt of the adjusted measurement power offset, the user equipment generates subsequent CQI values using the adjusted measurement power offset.

Abstract: A coax network unit (CNU) receives downstream bursts from a coax line terminal (CLT) and transmits upstream bursts to the CLT. The downstream bursts include start markers that indicate the beginnings of the downstream bursts and may also include pilot symbols. The downstream bursts are continuous across available resource elements in a matrix of subcarriers and orthogonal frequency-division multiplexing (OFDM) symbols. The available resource elements exclude resource elements in the matrix that carry the pilot symbols. The upstream bursts may include start markers indicating the beginnings of the upstream bursts and end markers indicating the ends of the upstream bursts. Respective upstream bursts are transmitted in respective groups of one or more resource blocks allocated to the CNU.

Abstract: A method is performed in a communication device that includes one or more media access control (MAC) entities, a coax physical layer (PHY), and a media-independent interface coupling the one or more MAC entities with the coax PHY. In the method, a bitstream is generated that includes data frames and characters corresponding to time windows in which the coax PHY does not transmit signals. The bitstream is provided to the coax PHY through the media-independent interface. Signals corresponding to the data frames are transmitted from the coax PHY during a transmit mode. The coax PHY enters a receive mode when the bitstream contains the characters corresponding to the time windows.
