In one embodiment, a system for allocating clients between radios of an access point is disclosed. The system includes a first antenna coupled to a first radio, a second antenna coupled to a second radio, and a monitoring radio coupled to the first antenna and second antenna. The system includes computer-readable instructions that cause the system to receive at the monitoring radio, a first client attribute from each of a plurality of first client devices, and a second client attribute from each of a plurality of second client devices, and provide each aforementioned attribute to an optimization function. The system determines, with the optimization function, that one of the first radio and second radio will optimize performance for at least one device of the plurality of first client devices and second client devices and steer the at least one device accordingly.

Described herein are variable gain amplifiers that selectively provide variable or tailored impedances at a degeneration block and/or feedback block depending at least in part on a gain mode of the variable gain amplifier. This advantageously reduces or eliminates performance penalties in one or more gain modes. The variable impedances can be configured to improve linearity of the amplification process in targeted gain modes. The variable gain amplifier can be configured to provide a low-loss bypass mode in a low gain mode to improve signal quality.

A frame error correction circuit may identify and correct errors in data frames provided to a receiver as part of a diversity communications scheme. The frame error correction circuit may further align the data frames so that the data frames can be compared. The frame error correction circuit may perform a bit-wise comparison of the data frames and identify inconsistent bit positions where bits in the data frames differ from one another. Once inconsistent bit positions have been identified, the frame error correction circuit may access a permutation table of permutations of bits at the inconsistent bit positions. In some implementations, the frame error correction circuit uses the permutation table to reassemble permutations of the data frames. In various implementations, the frame error correction circuit performs a CRC of each permutation of the data frames, and provides a valid permutation to a network.

An exemplary method comprises positioning a first antenna to receive a first signal from a second antenna, the second antenna comprising energy absorbing material that functions to expand beamwidth, receiving the first signal from the second antenna, detecting a plurality of gains based on the first signal, repositioning the first antenna relative to the second antenna to a position associated with an acceptable gain based on the first signal, removing at least some of the energy absorbing material from the second antenna to narrow the beamwidth of the second antenna, receiving, by the first antenna, a second signal from the second antenna, detecting a plurality of gains based on the second signal, and repositioning the first antenna relative to the second antenna to a position associated with an increased gain of the plurality of gains based on the second signal, the increased gain being greater than the acceptable gain.

A WTRU may include a memory and a processor. The processor may be configured to receive beam grouping information from a gNB or transmission and reception point (TRP). The beam grouping information may indicate a group of beams that the WTRU may report using group-based reporting. The group-based reporting may be a reduced level of reporting compared to a beam-based reporting. The group-based report may include measurement information for a representative beam. The representative beam may be one of the beams in the group or represents an average of the beams in the group. Alternatively, the representative beam may be a beam that has a maximum measurement value compared to other beams in the group. The group-based report may include a reference signal received power (RSRP) for the representative beam and a differential RSRP for each additional beamin the beam group.

In an aspect of the disclosure, an apparatus for wireless communication is provided. The apparatus may include several detectors, each of which may be configured to detect a signal received by a corresponding antenna of several antennas. The apparatus may include a processing system configured to detect a remote apparatus based on outputs from the detectors. The apparatus may include several modem radio frequency chips each including a corresponding detector of the several detectors, and a modem baseband chip including the processing system. The processing system may be configured to allow at most one of the detectors to output a detection declaration to the processing system at a time. The processing system may be configured to send a power-down command to and disconnect from each of the detectors that does not detect the signal from a corresponding antenna of the several antennas.

A payment device, comprising: a housing; and a controller disposed within the housing and configured to: receive at least one location signal, the at least one location signal being based, at least in part, on an antenna signal and representing a location of a payment transceiver or a range between the payment transceiver and an antenna: determine, according to the at least one location signal, whether the location of the payment transceiver is within a payment processing zone; determine whether the payment device is an approved payment device such that the payment device is approved to process payments from the payment transceiver; and process a payment from the payment transceiver only if, at least, the payment transceiver is within the payment processing zone and the payment device is an approved payment device.
