Abstract: Certain aspects of the present disclosure provide a technique for pre-bundling the received service data units (SDU) into an SDU bundle in a first communication layer before receiving a scheduling information from a second communication layer and adjusting the SDU bundle when the scheduling information is received.

Abstract: Techniques for re-using sequence number by multiple protocols in a protocol stack are described. In one design, at least one protocol data unit (PDU) from a first protocol may be received as at least one service data unit (SDU) at a second protocol, with each PDU being assigned a different sequence number by the first protocol. A sequence number for each SDU may be determined based on a sequence number for a corresponding PDU from the first protocol. A PDU may be formed by the second protocol based on the at least one SDU. A header may be generated for the PDU and may include (i) the sequence number and possibly a segment offset for the first SDU and (ii) a header block for each remaining SDU, which may include a segment length, a sequence number offset, and a segment offset for that SDU.

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: Systems and methodologies are described that facilitate efficiently communicating a data packet related to a protocol layer within a wireless communication system. The systems and/or methods can provide cross-layer optimization by directly transporting or communicating data to a particular protocol layer. In general, a MAC header can include data that indicates a protocol layer to which such data is directed or targeted. The MAC header can allow a portion of data (e.g., PDUs, SDUs, etc.) to bypass at least one protocol layer above the MAC protocol layer for efficient and optimized processing of such data.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in which an uplink semi-persistent scheduling release is received an HARQ ACK is determined whether to be transmitted in response to the received uplink semi-persistent scheduling release.

Abstract: A method includes sending to a receiving device from a transmitting device a Radio Link Control (RLC) re-transmission scheme selected from a plurality of RLC re-transmission schemes, and using the selected and sent scheme at least at one of the receiving device and the transmitting device. In another exemplary non-limiting embodiment the method includes detecting, at the receiver, a gap in RLC Protocol Data Unit (PDU) sequence numbers, associating a timer with the gap, and starting the timer when the gap is detected. In still another exemplary non-limiting embodiment, the method includes detecting a gap in a RLC PDU sequence, monitoring a HARQ channel for a period of time to determine if a predetermined bit has changed, and determining if a transmission is lost.

Abstract: Systems and methodologies are described that facilitate communicating a Buffer Status Report (BSR) from user equipment (UE) while reducing the employment of a RACH procedure. A BSR Prohibit time interval can be triggered by a receipt of uplink data to the UE. The BSR can be conveyed utilizing an uplink-shared channel (UL-SCH) if a Scheduling Request (SR) or a Semi-Persistent Scheduling (SPS) occurs within the duration of the BSR Prohibit time interval. The BSR can be communicated utilizing a RACH procedure if a SR or SPS occurs upon the expiration of the BSR Prohibit time interval.

Abstract: Systems and methodologies are described that facilitate enforcing quality of service requirements. A first timer is employed for each data packet arriving at a packet data convergence protocol layer of a wireless communications apparatus. The first timer can be configured based upon delay tolerance specified according to quality of service requirements imposed on the data packet. The data packet can be discarded if the timer expires before the data packet leaves the protocol data convergence protocol layer. In addition, a second time is utilized for the data packet as it arrives at a radio link control layer. The data packet can be discarded if the second timer expires before the data packet is successfully transmitted to a receiver.

Abstract: Indications are provided related to discontinuous reception (DRX) and release of semi-persistent scheduling (SPS) resources from a base station to an access terminal. A DRX indicator that provides a command to an access terminal to transition to DRX mode and a resource release indicator that identifies one or more SPS resources (e.g., uplink, downlink, . . . ) previously assigned to the access terminal that are released can be transmitted within a common transaction. The DRX indicator and the resource release indicator can be sent via disparate channels (e.g., PDCCH and PDSCH) within a single transmission time interval (TTI). The DRX indicator and the resource release indicator can be transferred within a common control message.

Abstract: Assigning power spectrum density to access terminals within a wireless network environment is provided. Assignment information that includes assignment of reverse link transmission resources is determined and a power control instruction is created for the assigned reverse link transmission resource. An assignment message that includes both the assignment information and the power control instruction is formatted and communicated to the access terminals. The assignment message includes a Reverse Link Power Control field that indicates a transmit power spectral density assigned by the access point to the reverse-link transmission by the terminal.
