    摘要: Techniques are provided for synchronized radio link control (RLC) and/or media access control (MAC). For example, there is provided a method that involves generating an RLC protocol data unit (PDU) according to a segmentation protocol for maximizing RLC PDU size while allowing the RLC PDU to fit into a defined MAC transport block, the RLC PDU comprising at least one RLC service data unit (SDU) or RLC SDU segment. The method may involve determining a PDU data size for each given RLC SDU. The method may further involve (a) attaching a given RLC SDU to the RLC PDU and (b) delivering the RLC PDU to a lower layer, in response to a SDU data size for the given RLC SDU exceeding a defined size limit.

    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: Systems and methodologies are described that facilitates managing assignment of available random access resources in order to minimize delay and random access load. A number of available random access resources can be defined by a network or a base station, wherein a user equipment can access the number of available random access resources via an information block. The user equipment can be randomly assigned or uniformly assigned to at least one of the number of available random access resources. Additionally, the network can adjust the defined number of available random access resources based upon reported delay, base station load, or historic load data for a base station.

    摘要: Confusion resulting from assigning the same node identifier to multiple nodes is resolved through the use of confusion detection techniques and the use of unique identifiers for the nodes. In some aspects a network may provide a time gap (e.g., an asynchronous time gap) during which an access terminal may temporarily cease monitoring transmissions from a source node so that the access terminal may acquire a unique identifier from a target node. In some aspects an access terminal may commence handover operations at a target node after determining whether the access terminal is allowed to access the target node. In some aspects a source node may prepare several target nodes for potential handover in the event confusion is detected or likely. Here, the source node may send information relating to the preparation of the potential target nodes to the access terminal whereby the access terminal uses the handover preparation information to initiate a handover at that target node.
