    摘要: Systems and methodologies are described that facilitate packet discard restriction in a wireless communication system. As described herein, a discard prohibit counter and/or other similar mechanism can be employed to limit the number of consecutive packets that are discarded by a transmitter, even in the event that the delay bounds of those packets have been exceeded. A discard prohibit counter as described herein can be updated upon a packet transmission and reset upon a packet discard to ensure that an acceptable number of packets are transmitted before a packet can be discarded. An acceptable number of packets can be selected based on device specifications, requirements of a data packet flow and/or traffic associated with the flow, or other suitable factors, and can be constant or adaptable to changes in network conditions. As further described herein, multiple counters can be separately maintained and utilized for a plurality of corresponding packet flows.

    摘要: 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.

    摘要: 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.

    摘要: A data packet communication system employs radio link control (RLC) transmission between a transmitter and a receiver with an Automatic Repeat Request (ARQ) arrangement whereby polling of the receiver is accomplished with reduced amount of redundantly transmitted data, such as between an access node and terminal. Upon a polling event, such as emptying of a transmission buffer of the transmitter, expiration of a polling timer, or reaching a radio link control (RLC) protocol data units (PDUs) count threshold, the transmitter sends a polling command to the receiver. This polling command is smaller than any of the RLC PDUs, which are conventionally resent with a polling bit set to evoke a STATUS PDU from the receiver. With evolving communication standards tending toward larger PDUs, such as in excess of a kilobyte for HSPA+ (High-Speed Packet Access Evolution) and 3GPP LTE (Long Term Evolution), this inefficiency can be of increasing impact.

    摘要: Method for reducing backlogged calls is disclosed. According to one embodiment, an initial parameter set providing an initial blocking probability and a timestamp is received. A current time index is determined based on the timestamp. Following, a current blocking probability is calculated based on the initial blocking probability and the current time index. The initial parameter set can also provide a delay period, a throughput rate, an expected new call rate and an initial backlog. The initial blocking probability can be determined, for example, from the throughput rate, expected new call rate and initial backlog. An elapsed time between the timestamp and the current system time is determined, and a current time index is determined by dividing the elapsed time by the delay period. A call request is blocked, for example, when a randomly generated number between 0 and 1 is less than the current blocking probability.

    摘要: Systems and methodologies are described that facilitate providing flow control feedback for controlling downlink data transmission rates. Various schemes can be utilized to send the flow control feedback from an access terminal to a base station. For example, a control PDU (e.g., MAC control PDU, PDCP control PDU) can be generated based upon a level of resource utilization of the access terminal, and sent to the base station for controlling the downlink data transmission rate. Following this example, a type of control PDU, a value included within the control PDU, etc. can be selected as a function of the level of resource utilization. By way of another illustration, a CQI report that includes a value selected as a function of the level of resource utilization associated with the access terminal can be generated and transmitted to the base station for controlling the downlink data transmission rate.

    摘要: Techniques for controlling data transmission in a wireless communication system based on hybrid automatic retransmission (HARQ) are described. In one design, a user equipment (UE) may determine the number of HARQ processes (Z) supported by the UE, e.g., based on the amount of resources available at the UE. The UE may send information indicative of the number of HARQ processes supported by the UE to a Node B. The UE may thereafter receive data from the Node B on up to Z HARQ processes. In one design, the UE may receive data for non-guaranteed bit rate (non-GBR) traffic on up to Z HARQ processes and may receive data for guaranteed bit rate (GBR) traffic on up to all HARQ processes available in the system. In another design, the UE may receive data for both GBR traffic and non-GBR traffic on up to Z HARQ processes.

    摘要: Techniques for performing in-order data delivery during handover in a wireless communication system are described. A user equipment (UE) may perform handover from a source base station to a target base station. The target base station may start a timer after a data path from a gateway to the UE has been switched from the source base station to the target base station. The target base station may receive forwarded packets for the UE from the source base station and may receive new packets for the UE from the gateway. The target base station may send the forwarded packets received prior to expiration of the timer to the UE before any new packets. The target base station may send the forwarded packets to the UE without waiting for the timer to expire and may send the new packets to the UE after the timer expires.

    摘要: Systems and methodologies are described that facilitate compressing headers for relay nodes. In particular, a plurality of internet protocol (IP) headers, tunneling protocol headers, and/or other routing headers in a packet can be compressed to facilitate efficient communications of packets between relay nodes and/or a donor access point. A donor or other upstream access point can be provided with a filter mask, bit stream, and filter mask identifier generated by a related relay node for packets having given static header data. Thus, the donor or other upstream access point can apply the filter mask to incoming packet headers, and where a resulting bit stream matches the received bit stream, can replace at least a portion of the packet headers with the filter mask identifier. The relay node can subsequently decompress the packet headers based on the filter mask identifier. Similar functionality can be used for compressing uplink communications.
