Abstract:
Aspects of the present disclosure provide techniques that may help address the effects of larger delay spreads in WiFi bands. Methods and apparatus are provided that perform wireless communications utilizing varying cyclic prefix lengths, varying repetition intervals, and varying symbol durations to ameliorate the effects of large delay spreads.
Abstract:
Certain aspects of the present disclosure provide a method for wireless communication at a wireless node, generally including communicating, via a first link, with a first access point (AP) device affiliated with a single mobility domain (SMD) entity, outputting, for transmission to the first AP device, a first message including a first indication that the wireless node is initiating a handover of the wireless node from the first AP device to a second AP device affiliated with the SMD entity, communicating with the second AP device via a second link during the handover after obtaining a second indication that context information has been transferred from the first AP device to the second AP device, and disabling the first link with the first AP device after obtaining a third indication that triggers the wireless node to disable the first link with the first AP device.
Abstract:
The present disclosure provides techniques for rate adaptation under congestion and latency constraints. The approaches described herein focus on aspects of latency, reliability, and power consumption instead of the traditional aspect of throughput. In an example, a method for rate adaptation is disclosed. The method may include determining whether to transmit a new packet or a retry packet. The method may also include reducing a maximum rate for a rate search in response to determining to transmit the retry packet. The method may further include transmitting the retry packet based on the reduced maximum rate.
Abstract:
Aspects of the present disclosure provide techniques for interleaving in single user (SU) preamble puncturing in wireless local area networks (WLANs). In one implementation, a wireless device can identify an SU preamble puncture transmission, encode information for the SU preamble puncture transmission to produce encoded bits, parse the encoded bits into multiple segments, parse the encoded bits among multiple resource units (RUs) within each of the multiple segments, and perform a tone interleaving of the encoded bits within each of the multiple RUs. These techniques can be used in a 6 GHz band, as well as a 2.4 GHz band or a 5 GHz band.
Abstract:
This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for determining one or more frequency channels for use in wireless communication. Some implementations more specifically relate to determining one or more frequency channels for unlicensed wireless communication in a frequency band also used for licensed wireless communication, such as a 6 GHz frequency band. In one aspect, a database system is configured to store information associated with existing wireless systems or links including the locations of such systems as well as characteristics of the wireless signals they transmit. In another aspect, a wireless communication device is configured to determine its location, transmit its location to a database system, and receive information from the database system usable to determine a frequency channel on which to communicate. In another aspect, a wireless communication device is configured to transmit a request including a unique identifier (ID) to a database system and to receive information from the database system usable to determine a non-blacklisted frequency channel on which to communicate.
Abstract:
Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to coordinating wakeup times of a receiver able to receive from both a wireless wide area network (WWAN) and a wireless local area network (WLAN). An exemplary method includes obtaining one or more messages (e.g., paging messages) via a receiver and taking one or more actions to align one or more first wakeup periods, during which the apparatus is scheduled to monitor for messages in a first wireless local area network (WLAN), with one or more second wakeup periods, during which the apparatus is scheduled to monitor for messages in a wireless wide area network (WWAN). The exemplary method continues by powering up the receiver for a duration spanning at least one of the one or more first wakeup periods and at least one of the one or more second wakeup periods, monitoring for messages in the first WLAN during the at least one of the one or more of the first wakeup periods, while the receiver is powered up for the duration, and monitoring for messages in the WWAN during the at least one of the one or more of the second wakeup periods while the receiver is powered up for the duration.
