    • Systems and methodologies are described that facilitate classification and identification of a channel associated with a wireless data transmission. As described herein, a channel designated for transmission of a packet can be selected from among multiple usable channels, based on which a bit at a predefined location in the packet can be set to a logical value indicative of the selected channel. As further described herein, extraction of the logical value from the predefined location and identification of the corresponding channel can be performed by a recipient of the packet without requiring parsing of the message. In one example described herein, a Dedicated Control Channel (DCCH) can be identified by setting a Logical Channel Identifier (LCID) bit in a DCCH packet to a predefined value. In another example, a Common Control Channel (CCCH) can be identified by embedding a Boolean constant within a message structure contained in a CCCH packet.
    • 描述了促进与无线数据传输相关联的信道的分类和识别的系统和方法。 如本文所述,可以从多个可用信道中选择指定用于分组的传输的信道,基于该信道,可以将分组中的预定位置处的比特设置为指示所选择的信道的逻辑值。 如本文进一步描述的,可以由分组的接收者从预定义位置提取逻辑值和对应信道的标识,而不需要解析该消息。 在本文描述的一个示例中,可以通过将DCCH分组中的逻辑信道标识符(LCID)位设置为预定义值来识别专用控制信道(DCCH)。 在另一示例中,可以通过在包含在CCCH分组中的消息结构内嵌入布尔常数来识别公共控制信道(CCCH)。

    • 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.
    • 描述了有助于实施服务质量要求的系统和方法。 对于到达无线通信装置的分组数据融合协议层的每个数据分组采用第一定时器。 可以基于根据对数据分组施加的服务质量要求指定的延迟容限来配置第一定时器。 如果定时器在数据包离开协议数据融合协议层之前到期,则可以丢弃数据包。 此外,当数据分组到达无线电链路控制层时,第二次被用于数据分组。 如果在数据分组成功发送到接收机之前第二定时器到期,则可以丢弃该数据分组。

    • Techniques for performing calibration and beamforming in a wireless communication system are described. In an aspect, a Node B may periodically perform calibration in each calibration interval with a set of UEs to obtain a calibration vector for the Node B. The Node B may apply the calibration vector to account for mismatches in the responses of the transmit and receive chains at the Node B. In another aspect, the Node B may perform beamforming to a UE by taking into account gain imbalance for multiple antennas at the UE. The Node B may determine a precoding matrix for beamforming by taking into account gain imbalance due to (i) different automatic gain control (AGC) gains for receive chains at the UE, (ii) different power amplifier (PA) gains for transmit chains at the UE, and/or (iii) different antenna gains for multiple antennas at the UE.

    • Systems, methodologies, and devices are described that facilitate transferring a subset of compression context from a source base station to a target base station during an inter-base station handover of a mobile device to facilitate establishment of compression context between the mobile device and target base station. The source base station can transfer a subset of compression context comprising static and semi-static context to the target base station during inter-base station handover to at least partially establish compression context between the mobile device and target base station prior to or during handover. The source base station can transmit, to the mobile device, indicator information related to compression context transferred. The target base station can at least partially establish compression context based on received subset of compression context to facilitate efficient communication with the mobile device and can establish any remaining portion of compression context with the mobile device after handover.
