    Abstract: A method and apparatus for power savings in a wireless local area network (WLAN) are disclosed. A station (STA) may receive parameters that associate the STA to a specific group of STAs and perform a channel access during a period that is allowed for the group of STAs based on the parameters. The STA may receive information regarding an access slot that is allowed for the group of STAs and access a channel during the access slot. The STA may receive a schedule for wake up from a doze state and goes in and out of the doze state based on the schedule. A highest channel access priority may be provided to a sensor or meter type of STA. The STA may indicate to an access point (AP) that the STA will not listen to a traffic indication map (TIM) or a delivery TIM (DTIM) in a beacon.

    Abstract: Beamforming, precoding, and feedback systems and methods are provided. For example, user equipment (UE) estimates an effective channel using a predetermined channel independent matrix or beamforming. Such an effective channel estimate along with other feedback information including a channel quality indicator (CQI) and a precoding matrix indicator (PMI) is fed back to an eNB. The eNB may precode data and may provide channel estimation at the eNB using a double codebook or double precoder. For example, the eNB may precode data based on the feedback information (e.g. using a channel dependent precoder) and the eNB may precode the data based on the channel independent matrix (e.g. using a channel independent precoder) that may be channel independent and/or preset (e.g. known to both eNB and UE), and may change each TTI. Such precoding along with scaling factors approximated from the PMI or CQI feedback may be used to enable the eNB to estimate a channel based covariance matrix and design the channel dependent precoder.

    Abstract translation: 提供波束形成，预编码和反馈系统和方法。 例如，用户设备（UE）使用预定的信道无关矩阵或波束形成来估计有效信道。 将这样的有效信道估计与包括信道质量指示符（CQI）和预编码矩阵指示符（PMI）的其他反馈信息一起反馈给eNB。 eNB可以预编码数据，并且可以使用双码本或双重预编码器在eNB处提供信道估计。 例如，eNB可以基于反馈信息（例如，使用信道相关预编码器）对数据进行预编码，并且eNB可以基于与信道无关的矩阵（例如，使用信道独立的预编码器）对数据进行预编码，该矩阵可以是信道独立的和/或 预置（例如，已知的eNB和UE），并且可以改变每个TTI。 这样的预编码以及从PMI或CQI反馈近似的缩放因子可以用于使得eNB能够估计基于信道的协方差矩阵并设计信道相关预编码器。
