    • Techniques for congestion control are disclosed. In an embodiment, a base station allocates a shared resource using a combination of zero or more individual grants and zero or more common grants, and generates a multi-valued busy signal in response to loading conditions that exceed a pre-determined level. In another embodiment, a subset of transmitting mobile stations reduce their transmission rate in response to a multi-valued busy signal. The subset may include autonomous transmission, commonly granted transmission, individually granted transmission, or any combination thereof. In various embodiments, rate adjustment may be probabilistic or deterministic. In an embodiment, a rate table is deployed, and a mobile station decreases or increases the transmission rate from one rate in the table to a lower or higher rate in the table, respectively, in response to the busy signal. Various other aspects provide efficient congestion control, avoiding excessive interference and increasing capacity.
    • 公开了拥塞控制技术。 在一个实施例中,基站使用零个或多个单独授权和零个或更多个公共授权的组合来分配共享资源,并且响应于超过预定电平的负载条件而生成多值繁忙信号。 在另一个实施例中,响应于多值忙信号,发送移动台的子集降低其传输速率。 该子集可以包括自主传输,通常授权的传输,单独授权的传输或其任何组合。 在各种实施例中,速率调整可以是概率的或确定的。 在一个实施例中,部署速率表,并且移动台响应于忙信号,分别将传输速率从表中的一个速率降低或增加到表中的较低或更高速率。 各种其他方面提供有效的拥塞控制,避免过度干扰和增加容量。

    • 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.
    • 描述了在无线通信系统中执行校准和波束成形的技术。 在一方面,节点B可以在每个校准间隔内周期性地执行与一组UE的校准,以获得用于节点B的校准向量。节点B可以应用校准向量来解决发送和接收的响应中的不匹配 在另一方面,节点B可以通过考虑UE处的多个天线的增益不平衡来向UE执行波束赋形。 节点B可以通过考虑由于(i)UE处的接收链的不同的自动增益控制(AGC)增益而考虑增益不平衡来确定用于波束成形的预编码矩阵,(ii)用于发射链的不同功率放大器(PA)增益 UE,和/或(iii)UE处的多个天线的不同天线增益。
