Abstract: The disclosure relates to methods, devices, and systems for wireless communications. A wireless communications system may support unicast and broadcast communications for different radio access technologies (RATs). To support the coexistence of different RATs, a user equipment (UE) may report, to a base station, a UE capability message containing a band combination including one or more bands for a first RAT (for example, New Radio (NR)) and one or more bands for a second RAT (for example, Long Term Evolution (LTE)) and an indication of a baseband budget for the second RAT for the band combination. In some implementations, the UE may transmit a broadcast interest indicator to the base station requesting a broadcast service. The base station may configure the UE with a carrier aggregation (CA) configuration based on the UE capabilities, such as the band combination and corresponding baseband budget for the second RAT, and the interest indicator.

Abstract: Minimizing conflicts between different radio access technologies (RATs) is disclosed herein which include monitoring, by a user equipment (UE), a first use of a UE Radio Frequency (RF) resource by a first Radio Access Technology (RAT). The UE monitors a second use of the UE resource by a second RAT. The UE is served by a current serving cell in the second RAT. The UE may also determine a percentage of conflict between a first use of a UE resource by a first RAT and the second use of the UE resource by the second RAT over a predefined period of time, and initiating, by the UE, a cell reselection attempt to one or more neighboring cells of a plurality of neighboring cells serving the second RAT based on the determined percentage of conflict exceeding a predetermined threshold.

Abstract: Diversity enhancement for multiple carrier systems is disclosed which includes generation of a multiplexed multicarrier radio frequency (RF) signal having N carriers organized to be accessed at a rate of one carrier access per multicast channel (MCH) scheduling period (MSP) per carrier of the N carriers, thereby requiring N accesses per MSP duration across the N carriers. The method may also include the base station transmitting the RF signal to a user equipment (UE). In other aspects, the diversity enhancements include the UE receiving a multiplexed multicarrier RF signal having N carriers. The UE may access the N carriers by performing one carrier access per MSP per carrier of the N carriers, thereby performing N accesses per MSP duration across the N carriers.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may receive a temporary mobile group identifier (TMGI) for a single cell point-to-multipoint (SC-PTM) service to which a user equipment (UE) is to be subscribed. The apparatus may configure a connected mode discontinuous reception (CDRX) schedule for the UE based at least in part on an SC-PTM discontinuous reception (DRX) schedule that corresponds to the TMGI. The apparatus may transmit the CDRX schedule 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: Examples described herein relate to managing communications for a first subscription and a second subscription of a wireless communication device, including, but not limited to, determining collision between activities of the first subscription over a first RAT and activities of the second subscription over a second RAT and reselecting from the second RAT to a third RAT for the second subscription.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The UE receives at least one of a unicast or a broadcast/multicast communication on a first frequency from a first cell of a serving eNB through a first receive chain. In addition, the UE receives at least one of broadcast/multicast signal, synchronization signal, or reference signal communication on a second frequency from a second cell of the serving eNB through a second receive chain without having received instruction from the serving eNB to receive the at least one of the broadcast/multicast signal, the synchronization signal, or the reference signal communication.

Abstract: Embodiments include methods implemented by a processor of a mobile communication device for managing tune-aways by a radio frequency resource supporting a first subscription to support a second subscription. The processor may determine a data loss ratio of the data of a media file that is lost in transmission to the mobile communication device. The processor may compare the data loss ratio of the data to a first data loss ratio threshold and a second data loss ratio threshold, and the processor may block a tune-away event of the radio frequency resource from the first subscription to the second subscription in response to determining that the data loss ratio of the data is greater than the first data loss ratio threshold and less than the second data loss ratio threshold.

Abstract: Methods, systems, and devices for wireless communication are described. Data for a broadcast or multicast service may be sent over a control channel. A network device may broadcast a message to indicate a plurality of enhanced multimedia broadcast multicast service (eMBMS) services offered by the network. The mobile device may transmit an indication to the network device identifying an eMBMS service of interest. The network device may transmit a configuration message before broadcasting or multicasting data of the eMBMS service of interest. The configuration message may notify the mobile device of a control channel on which to receive the data related to the eMBMS service. The network device may then broadcast or multicast the eMBMS service data on the control channel. The data may be segmented at a particular protocol layer and mapped to several transmission time intervals within each repetition of the control channel.
