Abstract: Disclosed are some examples of techniques for ranging and positioning of distributed devices to avoid local and/or periodic interference. For example, an initiator user equipment (UE) can broadcast a positioning reference signal (PRS) message of a current positioning session to responder UEs. One or more characteristics of PRS transmission associated with a first responder UE in the current positioning session can be determined. Based on the characteristic(s), interference with the first responder UE can be identified, which can cause the initiator UE to change the broadcast order of the responder UEs for a next positioning session.

Abstract: Systems and methods are described herein for inserting supplemental content into a QAM signal. A unicast QAM signal between a server and a client device for delivery of content is established. The QAM signal has a particular frequency corresponding to the channel on which it will be transmitted to the client device. A request or other signal may be received from the client device requesting that supplemental content be inserted into the QAM signal. A portion of the bandwidth of the QAM signal is allocated for the supplemental content. The supplemental content is transcoded into a supplemental QAM signal in the particular frequency. The supplemental content may be packetized content such as internet protocol-based content and may be retrieved from a server or database. The supplemental QAM signal is then inserted into the unicast QAM signal using the allocated portion of the bandwidth.

Abstract: Aspects are provided which allow an apparatus to efficiently indicate downgraded band combinations associated with carrier aggregation (CA) to a base station, in which one or more UE capabilities such as the DL MIMO of certain supported band combinations may be downgraded in exchange for other UE capabilities such as FD-MIMO and 256/1024QAM. The apparatus, which may be a UE, receives a request from a base station for information associated with downgraded band combinations and for information corresponding to at least one UE capability associated with each of the downgraded band combinations. After receiving the request, the UE sends, to the base station, information indicating the downgraded band combinations and the at least one UE capability. The UE may thus report downgraded band combinations for a subset of supported band combinations as requested by the base station, thereby minimizing capability reporting of the UE.

Abstract: A user equipment apparatus determines whether a transmission is received from a base station within a time window and skips measurement of a reference signal during a subsequent period, when a transmission is received from the base station within the time window. A base station apparatus configures a UE to monitor one or more reference signals associated with a beam pair link and transmits a first signal in a transmission to the UE. The base station determines whether the transmission is received at the UE within a time window and determines whether to transmit a reference signal, based on whether the transmission is received at the UE within the time window. Upon determining that the transmission was received at the UE, the base station may skip transmission of the reference signal or modify a time, a frequency, a power, and/or a reference signal offset for the reference signal.

Abstract: A predefined signal has been used to facilitate the detection of the clock rate difference between the transmitter and the receiver. First the predefined signal is to be detected by each of the sensors and its time frame boundary information is acquired by a detector. The detector is composed of a matched filter bank, an event detector and a state sequence detector. The phase error is derived with reference to a fixed reference stored. With each of the sensors updating its local clock to the same fixed reference they can be brought to an arbitrary close clock error with one another. Thus, by applying the method disclosed here the transmitter and all the receivers can have an arbitrary small clock rate error with respect to one another. The method described is really fast in the sense that the delay needed for the detection and adjustment is minimal.

Abstract: Systems, methods, and computer program product embodiments are disclosed for removing any fixed frequency interfering signal from an input signal without introducing artifacts that are not part of the original signal of interest. An embodiment operates by using a virtual buffer with a length that matches a length of one cycle of an interfering signal. The embodiment extracts the interfering signal into the virtual buffer. For a sample in the next cycle of the interfering signal that corresponds to a virtual memory location for the virtual buffer, the embodiment can update one or more physical memory locations of the virtual buffer that are in the vicinity of the virtual memory location. This use of virtual buffer can remove any interfering signal without creating the artifacts associated with conventional notch filters.

Abstract: A gear shifting technique has been developed in which modulation and equalization are shifted to achieve optional performance. In one form, two or more equalizers, each associated with a demodulator and message decoder, determine if the modulation being used can be increased in complexity in order to increase the channel throughput or determine if the modulation method should be reduced in complexity in order to improve the receiver error performance. The quality metrics can based on which equalizer-demodulator-decoder is set to first detect a valid message. Other factors can be considered with this technique such as a packet-error ratio and a signal-to-noise ratio. In a financial trading system, message erasures can be favored over errored messages by limiting the number of bit or symbol corrections permitted per message to less than the maximum possible for the selected decoding schemes.
