    摘要： Methods and apparatuses are provided that include counting devices for broadcast data services. The devices can be counted based on registrations received from the devices. This registration count can additionally or alternatively be used to determine whether further counting is desired. In addition, base stations can transmit counting requests to the devices using a paging message or other message such that idle mode devices can receive the counting requests. The idle mode devices can respond to the requests or send autonomous counting report by switching to an active mode for the purpose of responding or another purpose.

    摘要： Methods and apparatuses are provided that include decoding multicast broadcast communications where scheduling information related to a multicast channel is not properly received over a control channel. Media access control (MAC) packets can be decoded to determine whether a MAC subheader indicates the packet relates to a logical channel by indicating an associated channel identifier. Where the channel identifier of the MAC packet matches that of a requested logical channel, data in the MAC packet can be provided to a communications layer. Subsequent packets can be processed and provided to the communications layer until a different channel identifier is encountered.

    摘要： 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.

    摘要： Techniques are described for wireless communication. A first method may include classifying feedback received for a first downlink transmission over a shared radio frequency spectrum band; identifying an interference parameter for a subsequent downlink transmission; and scheduling the subsequent downlink transmission based at least in part on feedback classified in a feedback category associated with the identified interference parameter for the subsequent downlink transmission. The feedback may be classified in one of a plurality of feedback categories, and the classifying may be based at least in part on an interference parameter for the first downlink transmission. A second method may include identifying an interference parameter for a first downlink transmission received over a shared radio frequency spectrum band; generating feedback for the first downlink transmission; and sending, to a base station, the feedback along with an indication of the interference parameter.

    摘要： A method, an apparatus, and a computer program product for wireless communication are provided. In a first configuration, the apparatus maintains a first set of tracking loops associated with unicast signals and a second set of tracking loops associated with multicast/broadcast signals. In addition, the apparatus decoding at least one of a received unicast signal based on the first set of tracking loops or a received multicast/broadcast signal based on the second set of tracking loops. In a second configuration, the apparatus maintains a TTL and a FTL associated with unicast signals based only on received unicast signals. In addition, the apparatus receives a multicast/broadcast signal and decodes the received multicast/broadcast signal based on the TTL and the FTL maintained based only on the received unicast signals.
