Abstract: Methods and apparatus for formatting headers for data packets within a communication frame for use in a wireless communication system are presented. Formatting headers includes determining the size of a wireless communication frame, and formatting the payloads and associated headers within the communication frame according to the determined size. This formatting includes placing headers at the beginning of the frame before the data packets corresponding to the headers to optimize processing of the headers at a receiver. Formatting may also include formatting the headers according to a first format within the frame when the determined frame size is below a predetermined size to optimize the size of the headers, and formatting according to a second format within the frame size of the data packet is equal to or greater than the predetermined size to optimize processing for frames having large data packets.

Abstract: Systems and methodologies are described herein that facilitate efficient handling of packets (e.g., Packet Data Convergence Protocol (PDCP) Protocol Data Units (PDUs) or Service Data Units (SDUs)) in a wireless communication system. As described herein, a number of consecutive packets that are discarded due to a discard timer expiration event and/or other causes can be monitored and compared to a number of tolerated consecutive discarded packets. If the number of consecutive discarded packets does not exceed the number of tolerated consecutive packets, conventional processing operations such as header modification and compression, ciphering, or the like can be omitted for respective packets subsequent to a discarded packet, thereby significantly reducing processing overhead. As further described herein, the number of tolerated consecutive discarded packets can be chosen to maintain header compression (e.g.

Abstract: Methods and apparatus for communicating IP datagrams efficiently within communication links employing variable frame sizes bundles IP datagrams into data payloads. The number of datagrams that can fit within a current frame size is determined, a bundle header indicating that the bundle header is associated with a bundled IP datagram is generated that includes information for unpacking bundled IP datagrams. The bundle header is joined to one or more IP datagrams to form a data payload that is communicated as a frame payload without indicating in a frame header that the frame includes bundled IP datagrams. Information in the bundle header enables a receiver processor to extract the IP datagrams from the frame payload without requiring modifications to the frame header. A bundle header may precede each IP datagram, or one bundle header may include a map IP datagrams in the frame payload.

Abstract: Methods and apparatuses are provided that facilitate providing quality of service for similar priority logical channels at least in part by assigning dynamic priority levels to the logical channels to allow certain logical channels to be assigned resources before other logical channels. Dynamic priority levels can be assigned based at least in part on a total accumulated used bytes of a given logical channel scaled by a prioritized bit rate of the logical channel. Thus, logical channels with a lower number of total accumulated used bytes scaled by the prioritized bit rate can be assigned higher priority to ensure resources are assigned to the logical channels. Moreover, the dynamic priority levels can be normalized to align the dynamic priority levels within certain values so as not to interfere with other logical channels of different assigned priority.

Abstract: Devices and methods are provided for expedited recovery from radio link failure or the like. In one embodiment, the method involves collecting at least one optional system information block (SIB) during connected mode, wherein the at least one optional SIB comprising neighbor information. In another embodiment, the method involves storing dedicated information provided by a base station through a dedicated channel. The method generally involves using the neighbor information and/or dedicated information for cell selection, in response to the radio link failure.

Abstract: Systems and methodologies are described that facilitate collecting consistent system information when entering a cell during cell selection and/or cell re-selection in a wireless communication environment. SIB(s) can be received while lacking modification period information (e.g., modification period boundary, modification period duration, . . . ). Further, the SIB(s) can be stored in memory with corresponding SFN(s) at which the SIB(s) are respectively received. Thereafter, the modification period information can be identified (e.g., from a SIB2, . . . ). Moreover, an evaluation can be effectuated to determine whether to retain or discard the SIB(s) from memory as a function of the modification period information and the corresponding SFN(s). Further, whether to retain or discard the SIB(s) from memory can be based upon a value tag.

Abstract: A method of wireless communication includes acquiring at least one non-required system information from a cell while in a radio resource control connected state. The non-required system information is system information that is not required in the radio resource control connected state. The method includes transitioning from the radio resource control connected state to a radio resource control idle state on the cell without acquiring the at least one non-required system information.

Abstract: Explicit signaling of End of Handover (EoH) advantageously indicates when user equipment (UE) has stopped using Packet Data Convergence Protocol (PDCP) handover mode. Radio Link Control (RLC) Acknowledge Mode (AM) delivers in order ensuring that all reordered packets have been received with no risk of delivering a gap packet when no longer in handover mode that would otherwise cause Hyper Frame Number (HFN) to be out of synchronization. Substantially at a time evolved Base Node (eNB) determines a gap will not be filled, eNB can convey an EoH indication to a served UE and can then deliver the PDCP Service Data Units (SDUs) with gaps to upper layers without delay.

Abstract: Systems and methodologies are described that facilitate utilizing hybrid automatic repeat/request (HARQ) in system access communications. A HARQ entity is provided that manages a plurality of HARQ processes, which can typically use new data indicators (NDI) to determine when received data is a new transmission or retransmission. For resource grants, the HARQ entity can determine whether the communication is a new transmission or retransmission based on the type of message that contains the grant. In addition, an address comprised within the message, a previous use of the HARQ process, and/or the like can further be utilized to determine whether the message is a new transmission or retransmission. Once determined, the HARQ entity can provide the message to the appropriate HARQ process along with the indication of new transmission or retransmission.
