摘要： Method and apparatus for transmission and reception of a Greenfield preamble are provided. In the method and apparatus, the Greenfield preamble may be a single user (SU) preamble or a multi user (MU) preamble. As an MU preamble, the Greenfield preamble includes a short training field (STF), a first long training field (LTF), a first signal (SIG) field, at least one additional LTF, and a second SIG field. Additionally, the Greenfield preamble may be utilized for efficient transmission and reception of control information to wireless devices, whereby the control information may be indicated using the STF, the first LTF, or the first or second SIG fields.
摘要翻译：提供了一种用于发送和接收绿田前置码的方法和装置。在该方法和装置中，格林菲尔德前导码可以是单用户（SU）前导码或多用户（MU）前导码）。作为MU前导码，绿田前置码包括短训练场（STF），第一长训练场（LTF），第一信号（SIG）场，至少一个附加的LTF和第二SIG场。此外，绿田前置码可用于向无线设备的控制信息的有效发送和接收，由此可以使用STF，第一LTF或第一或第二SIG字段来指示控制信息。

摘要： A method and apparatus may be configured to support coordinated orthogonal block-based resource allocation (COBRA) operations. An access point (AP) may be configured to indicate to a plurality of stations (STA)s that it may support COBRA. Each WTRU may be configured to indicate to the AP that it can support COBRA as well. The AP may be configured to transmit a COBRA controller information element (IE) comprising a plurality of fields to each of the WTRUs. Each WTRU may be configured to transmit a COBRA controllee IE comprising a plurality of fields. STA grouping management, group maintenance, channel access, beamforming, sounding and frequency and synchronization procedures are also described.

摘要： A method for use in a wireless station includes receiving a fast initial link setup discovery (FD) frame from an access point (AP) between instances of a full beacon frame and determining whether to associate with the AP based on the received FD frame. The FD frame includes FD frame contents and a FD frame control field. The FD frame control field includes a service set identifier (SSID) length field, corresponding to a length of a variable length SSID field in the FD frame contents; and any one or more of: a capability presence indicator, an access network options presence indicator, a security presence indicator, an AP configuration change count presence indicator, or an AP next target beacon transmission time presence indicator. Each of the presence indicators is used to indicate whether a corresponding field is present in the FD frame contents.

摘要： A method and apparatus may provide multi-user parallel channel access (MU-PCA) and/or single-user parallel channel access (SU-PCA) using transmit and/or receive with symmetrical bandwidth, in the downlink (DL), uplink (UL), or combined DL and UL. SU-PCA and MU-PCA may support unequal modulation and coding schemes (MCS) and unequal transmit power. Medium access control (MAC) layer, Physical layer (PHY), and mixed and PHY layer methods and procedures may support UL, DL and combined UL and DL SU-PCA and MU-PCA using transmit and/or receive with symmetrical bandwidth. MU-PCA and/or SU-PCA may also be supported by MAC and PHY layer designs and procedures for downlink, uplink and combined uplink and downlink using transmit/receive with asymmetrical bandwidth.
