  • Patent number: 10172113
    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.

  • Patent number: 9924471
    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.

  • Publication number: 20180070361
    Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may transmit and receive signals using radio frequency (RF) chains associated with multiple radios configured for different radio access technologies (RATs). The wireless device may determine a signal of interest for each physical antenna of a set of RF chains associated with a RAT used to receive a desired signal. RF chains of the wireless device may be mapped to a virtual antenna configuration, which may be used to mitigate interference and subsequently process the desired receive signal. A determined interference channel may be used along with the determined signal of interest to map the RF chains to the virtual antenna configuration.

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.
