TERRESTRIAL WIRELESS POSITIONING IN LICENSED AND UNLICENSED FREQUENCY BANDS

Disclosed are techniques for determining a distance (or range) between a first wireless entity and a second wireless entity. In an aspect, the first wireless entity transmits a first positioning reference signaling (PRS) signal to the second wireless entity at a first time, where the first PRS signal is received by the second wireless entity at a second time, and receives a second PRS signal from the second wireless entity at a third time, where the second PRS signal is transmitted by the second wireless entity at a fourth time. The first wireless entity enables the distance to be determined by a location computing entity, for example, by a location server, based on the first, second, third, and fourth times. The first wireless entity may be a mobile device or a base station and the second wireless entity may be the other of the mobile device or base station.

METHOD AND APPARATUS FOR COLLECTING AND PROCESSING INTERFERENCE INFORMATION

A system that incorporates the subject disclosure may perform, for example, a method for receiving interference information from each of the plurality of communication devices detecting interference information in a plurality of segments of a radio frequency spectrum, correlating the interference information of the plurality of communication devices to generate correlated information, and identifying a plurality of interferers according to the correlated information. Other embodiments are disclosed.

Method and apparatus for mitigating signal interference in a feedback system

A system that incorporates the subject disclosure may include, for example, a process that includes adjusting a filter in electrical communication between an input terminal and a demodulator. The filter is applied to an information bearing signal, e.g., to mitigate interference, received at the input terminal, resulting in a filtered signal. An error signal is received, indicative of errors detected within information obtained by demodulation of a modulated carrier of the filtered signal. A modified filter state is determined in response to the error signal and the filter is adjusted according to the modified filter state, e.g., to improve mitigation of the interference. Other embodiments are disclosed.

Creating Library of Interferers

A system includes a method for detecting a signal interference in a communication signal of a wireless communication system. An identified source of the signal interference is determined according to an interference profile of a plurality of interference profiles associated with an interference profile library having information that approximates characteristics of the signal interference. The signal interference of the communication signal is mitigated according to an interference parameter associated with the identified source by filtering the communication signal according to the interference parameter.

Timing parameter management for bandwidth part switching

Bandwidth part (BWP) switching may benefit a wireless communications system. Such BWP switching may include indication of one or more timing parameters used for time domain resource allocation. For example, the timing parameters may be indicated based on an index to a look-up table (e.g., a bit field in a control transmission). In some cases, one or more tables may be configured for a given BWP, and different tables may contain a different number of rows. The size of the bit field indexing the table may in turn depend on the number of rows. When switching from a first BWP to a second BWP, the size of the bit field may be based on the table of the first BWP, but the bit field may index the table of the second BWP. Techniques supporting improved timing parameter management during BWP switching are discussed herein.

Narrowband communication for different device capabilities in unlicensed spectrum

Methods, systems, and devices for wireless communication are described. Resources for narrowband communication in an unlicensed radio frequency spectrum band may be configured and allocated based on resource availability, regulatory constraints, and device capability or category. A narrowband wireless device, such as a machine type communication device or other relatively low complexity device, may communicate using one or more narrowband carriers, which may occupy between one tone and multiple resource blocks in an unlicensed spectrum band (e.g., any number of resources between one (1) tone and multiple resource blocks (RBs)). Different device types may thus be configured differently as they move between geographic regions. The base station may then communicate with the narrowband mobile device based on the resource allocation and the carrier configuration.
