摘要： A method and apparatus are disclosed for identifying different types of reception failures of a packet. A station (STA) may receive a packet from a transmitting STA and determine whether it is properly received by performing at least one check of a plurality of checks. The STA may determine that reception of the packet was not properly received due to a reception failure based on the at least one check and may generate a negative acknowledgement signal (NACK) signal including an indication of the reception failure cause to enable the transmitting STA to remediate the reception failure cause. The least one check includes determining whether a frame check sequence (FCS) passes, whether a CSMA wireless medium remains busy immediately after an expected packet transmission time, whether there is a power spike during reception of the signal, or whether there are Short training field (STF) and Long Training Field (LTF) correlations.
摘要翻译：公开了用于识别分组的不同类型的接收故障的方法和装置。站（STA）可以从发送STA接收分组，并且通过执行多个检查的至少一个检查来确定它是否被适当地接收。 STA可以基于至少一个检查确定由于接收失败而未正确接收到分组的接收，并且可以生成包括接收故障原因的否定确认信号（NACK）信号，以使发送STA能够修复接收故障原因。至少一个检查包括确定帧校验序列（FCS）是否通过，CSMA无线介质是否在预期分组传输时间之后立即忙碌，接收信号期间是否存在功率尖峰，还是存在短训练场（STF）和长训练场（LTF）相关性。

摘要： WTRUs, access points (APs) and methods thereon are disclosed. A method on a WTRU may include receiving a message from an AP that comprises a beamformee capability element; sending a second message to the AP that comprises a beamformer capability element; and receiving, from the AP, a third message in response to the second message that indicates a group to which the WTRU is assigned. The group may be based on the beamformer capability element and the group may indicate UL transmission information to be used by the WTRU. A method on an AP may include determining a group for multiple WTRUs based on a received beamformer capability element. A method on a WTRU may include sending to an AP a message with a low overhead preamble for UL MU-MIMO. The low overhead preamble may include LTFs that enable the AP to distinguish the WTRU from other WTRUs.

摘要： Techniques for configuring and switching a resource assignment mode for a plurality of component carriers are disclosed. A wireless transmit/receive unit (WTRU) has a capability of supporting multiple resource assignment modes such that a resource assignment mode is configured for a plurality of component carriers that are allocated for the WTRU, and the WTRU attempts to decode a control channel based on the configured resource assignment mode. The resource assignment mode may be configured for the WTRU via higher layer signaling. The resource assignment mode may be specific to the WTRU, or specific to a component carrier or a group of component carriers. The resource assignment mode may be configured separately for a downlink component carrier and an uplink component carrier. The resource assignment mode includes a separate assignment mode with component carrier indication, a separate assignment mode without component carrier indication, or a joint assignment mode.
