摘要： Methods and apparatuses for preventing overflow at a receiver buffer are provided. Data packets of varying size are received into a receiver buffer and quantified by a byte counter to determine an amount of data in the receiver buffer at a given time. A data capacity status for the receiver buffer is then generated as a function of the amount of data in the receiver buffer.

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： Systems and methods are provided for a signaling an ongoing communication of a data unit in a data packet is to be aborted. Upon a determination to abort an ongoing communication is made, a code-point in a data unit header is utilized to indicate the ongoing communication is to be aborted. A first class of code-point is a dedicated, predefined abort data unit field header. A second class of code-point is a combination of a set of existing, predefined data unit header fields, at least one data unit header field in the combination holds a value that is either invalid or legitimate yet unlikely to occur. Conveying code-point(s) to indicate termination of an ongoing communication of a data unit in a data packet in a regular communication mitigates transmission disruption and saves channel capacity.

摘要： A data packet communication system employs data encryption in a packet data convergence protocol (PDCP) and radio link control (RLC) in Layer 2 of transmission between a transmitter (TX) and a receiver (RX). A single sequence number is used for both the PDCP and RLC to reduce overhead by signaling a TX PDCP first ciphering sequence number to the RX prior to encrypted data packet communication. A sequence number accompanies each RLC PDU, which can encompass concatenated or segmented service data units (SDUs) from the higher layer PDCP. This sequence number is sufficient for the RLC to perform re-ordering, gap detection, retransmission, etc., while also allowing the RX upper layer PDCP to reconstruct a sequenced value used to encrypt content.

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： A transmitter directed, distributed receiver using path diversity provided by the distribution of the receiver. Advantage is taken of the uncorrelated variations over time in the condition of channels between a common transmitter and several users. The greater the variation in the channel condition of a particular channel over time, the greater the increase in total system throughput provided. An access metric represents the instantaneous channel condition of the communication system between each user and the transmitter with respect to the average channel condition of each channel. Alternatively, the access metric represents the instantaneous channel condition with respect to the average data throughput over that channel. The common transmitting station uses the access metric to directly compare the desirability of granting each channel access with the desirability of granting each other channel access. The user that has the greatest access metric is provided access to the channel.

摘要： In a communication system (100), a method and apparatus provide for efficient power control between base station (101) and mobile stations (102-104). A controller is configured for determining duty cycle of a communication channel, and for controlling power level of the communication channel based on the determined duty cycle. The controller may compare the determined duty cycle against a duty cycle threshold. An adjustment for controlling power level may be based on the comparison.
