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： Methods and apparatuses are provided that include enhancing decoding of multicast broadcast control communications, which can be of a relatively large size. A configuration message related to a broadcast channel structure can be received in multiple instances and/or segmented data units. A receiver can combine multiple instances and/or accumulate segmented data units to obtain and/or decode a control channel over which the configuration message is communicated. Communicating segmented data units of the configuration message can allow a broadcast station to utilize a lower data rate, more reliable modulation and coding scheme to encode the configuration message.

摘要： Carrier aggregation to enhance Evolved Multimedia Broadcast Multicast Service (eMBMS) includes transmitting unicast signaling for a unicast service on an anchor carrier to mobile entities, transmitting eMBMS signaling on a second carrier different from the anchor carrier to the mobile entities for use with the unicast signaling, and various techniques for practical application of carrier aggregation for eMBMS enhancement. In addition, allocating subframes used for MBMS on a Single Frequency Network (MBSFN) includes allocating at least a portion of one or more subframes otherwise reserved for unicast subframes on a mixed carrier to provide an increased allocation of subframes carrying MBSFN information, transmitting MBSFN signals on the increased allocation of subframes, and more detailed aspects.

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.
