Abstract: 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.

Abstract: A method for mitigation of lost resource allocation synchronization between a user equipment (UE) and an evolved Node B (eNodeB) during a Hybrid Automatic Repeat Request (HARQ) transmission and/or retransmission process is described. The method includes determining whether resource allocation is out of synchronization between a user equipment (UE) and an evolved Node B (eNodeB) during a hybrid automatic repeat request (HARQ) transmission and/or retransmission process. The method further includes mitigating a loss of resource allocation synchronization between the UE and the eNodeB during the HARQ transmission and/or retransmission process.

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: Certain aspects of the present disclosure propose methods for protecting channel quality indicator (CQI) modulation symbols in a subframe (e.g., a localized frequency division multiplexing (LFDM) subframe). For some aspects, a timing adjustment method may be utilized to adjust time of a UE with respect to an eNodeB. The timing adjustment method may introduce a positive time offset to be used for reducing time mismatch between the UE and the eNodeB. In another aspect, a buffer may be used at the eNodeB to store symbols received by the eNodeB before removing the cyclic prefix information from the subframe. The eNodeB may use the stored symbols and an artificial time delay to ensure that the CQI information is protected. For some aspects, the CQI modulation symbols may not be located at the beginning of an LFDM symbol.

Abstract translation: 本公开的某些方面提出了在子帧（例如，局部频分复用（LFDM）子帧）中保护信道质量指示符（CQI）调制符号的方法。 对于一些方面，可以利用定时调整方法来调整UE相对于eNodeB的时间。 定时调整方法可以引入正时间偏移，以用于减少UE与eNodeB之间的时间失配。 在另一方面，可以在eNodeB处使用缓冲器来存储由eNodeB接收的符号，然后从子帧中删除循环前缀信息。 eNodeB可以使用存储的符号和人造时间延迟来确保CQI信息被保护。 对于一些方面，CQI调制符号可能不位于LFDM符号的开头。
