摘要： This disclosure provides methods, apparatuses and systems for placing a range extender, RE, based on a distance between the RE and an access point, AP. An RE may determine a distance between the RE and AP based on round trip timing, RTT, information. The RE exchanges (1210, 1310) fine timing measurement, FTM, frames with the AP. The RE determines (1220, 1320) a distance between itself and the AP based on the RTT information. Based on the distance between the RE and AP, the RE may provide a coarse placement indicator for improving the RE's location. The RE also determines (1230, 1330)) a signal strength or channel state information, CSI, with respect to the AP. Based on the signal strength or the CSI, the RE provides (1250, 1350) a fine placement indicator indicating the RE may be placed nearer or further from the AP, or remain at its current location.

摘要： Methods, systems, and devices for wireless communication are described. A ranging message procedure may employ protection by modifying a cyclic prefix of the ranging message to prevent an attacking device from transmitting a time-advanced copy of the cyclic prefix during symbol of the copied signal. For example, the modified cyclic prefix may include pseudo random training sequences or a set of zero-value symbols. The receiving device may determine a channel estimation technique that accounts for the modified cyclic prefix. The wireless devices performing the ranging measurement process may determine a modulation and coding scheme (MCS) for the ranging message. The wireless devices may negotiate an MCS value and cyclic prefix configuration for the ranging measurement process. In some examples, the ranging message be encoded by applying a sequence of phase rotations or amplitude variations to the base sequence used to generate the sounding training signal.

摘要： Methods, systems, and devices for wireless communication are described. A user equipment (UE) may monitor a narrowband (e.g., a single carrier, anchor carrier, etc.) for a control message that includes a grant for downlink data transmissions. The narrowband containing the control message may be a portion of a system bandwidth. The UE may then monitor a wideband (e.g., all or multiple carriers of the system bandwidth) for data according to the control message. Monitoring the wideband may include additional or alternate circuitry being powered (e.g., receiver circuit switching) to enable reception on an increased range of frequency spectrum. In some examples, a gap or narrowband data transmission may be scheduled between the control message and the grant to allow grant processing and receiver circuitry switching at the UE. In some cases, the control message and data transmission may be received in the same or different transmission time intervals (TTIs).

摘要： Methods, systems, and devices are described for synchronization in mesh satellite communications. The arrival time of the gateway signal may be used to set a start of receive frame time for a terminal. A received control signal from the gateway may then be used to set a start of transmit frame time for the user terminal. The distance between the satellite and the gateway may change. Ephemeris data, various collections of terminal measurements, or terminal sync bursts may be used to modify start of transmit frame or start of receive frame settings for the terminal or gateway.

摘要： A process is described to build frames for transmission with a modcode adapted to the signal quality of a destination terminal. The order of transmission may be based, at least in part, on the age of a packet as defined by a timestamp. Data packets assigned to the same modcode may be grouped in the same frame, with precedence given to older timestamps. For data packets with certain quality of service designations, timestamps may be modified to expedite forwarding. The amount of modification may, for example, be based on factors related to delay and latency.

摘要： Systems, devices, methods, and software are described for the reception of wireless video signals at a receiver. Mobile digital broadcast video signals may be received, the signals corresponding to a series of video channels formatted according to a concatenated transmission standard. This series of video channels may be demodulated. A selected subset of two or more of the demodulated video channels may then be decoded decoded, with the non-selected video channels excluded from decoding. When the number of demodulated channels to be decoded is reduced, various power management techniques are described which may be used to reduce power consumption.

摘要： A resynchronization signal (RSS) may extend across multiple physical resource blocks (PRBs) or subframes, which may cause the RRS to be scheduled to overlap with other downlink transmissions. Methods, systems, and devices for wireless communications are described for management of RSS and one or more other transmission types that may have overlapping wireless resources with the RSS. If one or more other downlink transmissions are scheduled for resources that overlap with resources scheduled for an RSS transmission, the UE may receive the RSS transmission or the one or more other downlink transmissions, or a combination thereof, based on a prioritization of the transmission types of the one or more other downlink transmissions relative to RSS. The RSS transmission or the one or more other transmissions may be delayed, dropped, punctured, or rate-matched when the RSS transmission and the one or more other downlink transmissions conflict.
