摘要:
Systems, apparatus, and methods to provide an indication of frequency resource unit (RU) allocation from a wireless access point (AP) to one or more station devices (STA) are disclosed. The AP may be configured to generate a protocol data unit including a high efficiency wireless (HEW) preamble that indicates the RU allocation corresponding to each of the STA. The indication of the RU allocation for each of the STA, as disclosed herein, may be encoded in fewer bits than providing a bitmap of the RU allocation for each of the STA. A predetermined RU pattern may be used to map RU (e.g., 26 tone units, 52 tone units, etc.) to a RU allocation index. This RU allocation pattern may be efficiently communicated to each of the STAs in the HEW preamble of the protocol data unit.

A License Assisted Access (LAA) enhanced NodeB (eNB), user equipment (UE) and communication methods therebetween operating in a Long Term Evolution unlicensed band (LTE-U) are generally described. The eNB may transmit a request to the UE for information regarding a Wireless Local Area Network (WLAN) over which the UE may be able to communicate. The WLAN information may include an LTE-U channel and time window for reporting. The UE may obtain the WLAN information through communication with an access point (AP). Measurement information of the LTE-U channel may also be obtained by or on behalf of the UE. The UE may transmit the WLAN information to the eNB. The eNB may use the WLAN information or submit the WLAN information to a network entity to perform channel selection, UE grouping or localization, appointing delegate UEs to perform channel sensing or scheduling UEs in a same group or proximity.

Certain embodiments herein relate to stream allocation indication for high efficiency wireless networks. A frame may include a HE-SIG-B field having a common part and an STA-specific part used to indicate multi-user multi-input multi-output (MU-MIMO) resource allocation. In some embodiments, a frame may include an HE-SIG-B field only having an STA-specific part used to indicate resource allocation.

Example systems, methods, and devices for extending range of WiFi networks are discussed. More specifically, methods for extending range of a Wi-Fi network are disclosed. The method may include the operations of appending, by a network device, one or more codebits to one or more original codebits or coded symbols, sending, by the network device, the original codebits or coded symbols and the appended codebits to an interleaver or a constellation mapper for transmission. The original codebits or coded symbols and the appended codebits may be sent over a plurality of subcarriers. Methods, apparatus, and systems described herein can be applied to 802.11ax or any other wireless standard.

Apparatuses, methods, and computer readable media for indicating a communication and information in a signal field are disclosed. A high-efficiency wireless local area network (HEW) device comprises circuitry is disclosed. The circuitry may be configured to: generate a HEW packet comprising a legacy signal (L-SIG) field, where the L-SIG field comprises a plurality of subcarriers, and an R-L-SIG field, where the R-L-SIG field comprises a repeat of the plurality of subcarriers partitioned into a plurality of groups, and where information is encoded into one or more groups of the plurality of groups by a same modulation to each subcarrier partitioned into the corresponding group. A HEW device comprising circuitry is disclosed. The circuitry may be configured to: receive a L-SIG field; receive a R-L-SIG field; and determine whether the R-L-SIG field is a repeat of the L-SIG field with piggybacked information.

This disclosure describes systems, methods, and devices related to long training field (LTF) sequence security protection. A device may determine a null data packet (NDP) frame comprising one or more fields. The device may determine a first long training field (LTF) and a second LTF, the first LTF and the second LTF being associated with a first frequency band of the NDP frame, wherein time domain LTF symbols of first LTF and the second LTF are generated using different LTF sequences. The device may determine a third LTF and a fourth LTF, the third LTF and the fourth LTF being associated with the a second frequency band of the NDP frame, wherein time domain LTF symbols of third LTF and the fourth LTF are generated using different LTF sequences. The device may cause to send the NDP frame to an initiating or a responding device. The device may cause to send a location measurement report (LMR) frame to the initiating or the responding device, wherein the LMR comprises timing information associated with the first frequency band and the second frequency band.

Embodiments herein relate to wireless communication using combined channel training and physical layer header (SIG) signaling. Devices that comply with the 802.11ax or High Efficiency WLAN (HEW) standard may generate and transmit packets that include such combined information. The combined information may be beamformed to a receiver device via an OFDM signal, which may be decoded by the receiver device to obtain subsequent data included in the signal. For example, initial training symbols associated with channel training subcarriers in the signal may be detected and used to perform a rough estimate of the channel. The rough estimate may thereafter be refined using data symbols detected from adjacent data subcarriers using the channel training symbols. In this way, data subcarriers may also be used to determine a channel response along with channel training subcarriers. Channel training information may be transmitted with data, such as user-specific information, in a single symbol.

Embodiments described herein relate generally to a user equipment (“UE”) that is to transmit and receive signals associated with synchronization. The UE may be receive signals associated with synchronization from a plurality of synchronization sources, such as an evolved Node B (“eNB”), a global navigation satellite system (“GNSS”), or another UE. The UE may synchronize to a signal received from a synchronization source based on a priority associated with that synchronization source and/or signal. However, if the UE does not receive any signals associated with synchronization, the UE may generate and transmit a signal that indicates a request for synchronization.
