Abstract: A wireless communication device receives wireless communications comprising omnidirectional reference signals, beam-formed reference signals, and beam-formed user data. The wireless communication device determines a difference between omnidirectional reference signal quality and beam-formed reference signal quality. The wireless communication device selects an omnidirectional network antenna configuration based on the difference between the omnidirectional reference signal quality and the beam-formed reference signal quality. The wireless communication device transmits wireless signaling indicating the selected omnidirectional network antenna configuration. Responsive to the wireless signaling, the wireless communication device receives additional wireless communications comprising omnidirectional reference signals and omnidirectional user data. In some examples, the network antenna configurations comprise Long Term Evolution (LTE) Transmission Modes (TMs).

Abstract: A wireless communication network comprising a donor base station (BS) and a repeater chain wherein a location controller stores a repeater chain BS identifier (ID) associated with a repeater chain location. The donor BS broadcasts a BS ID and serves a repeater chain. The repeater chain broadcasts the donor BS ID and the repeater chain BS ID. The communication server system receives a location request for a User Equipment (UE) and establishes data connectivity between the UE and the location controller over the donor BS and the repeater chain. The UE transfers the repeater chain BS ID to the location controller, and the PDE translates the repeater chain BS ID to the repeater chain location and transfers the repeater chain location.

Abstract: A wireless access point uses both Carrier Aggregation (CA) and Multi-User Multiple Input Multiple Output (MU-MIMO). In the wireless access point, processing circuitry determines when Radio Frequency (RF) signal strength for a User Equipment (UE) exceeds a CA threshold. Transceiver circuitry transfers data to the UE over wireless CA links when the RF signal strength exceeds the threshold. The transceiver circuitry transfers data to the UE over different wireless links when the RF signal strength does not exceed the threshold. The processing circuitry determines MU-MIMO load on the wireless access point. The processing circuitry increases the CA threshold when the MU-MIMO load increases. The processing circuitry decreases the CA threshold when the MU-MIMO load decreases.

Abstract: An Orthogonal Frequency Division Multiplex (OFDM) base station transfers a wideband measurement request for a wideband OFDM spectrum to User Equipment (UE). The base station receives a wideband signal metric from the UE, and if the wideband signal metric is below a threshold, the base station transfers a sub-band null request to shield a sub-band of the wideband spectrum to an adjacent base station. The base station also transfers a sub-band measurement request to the UE. The base station receives a sub-band signal metric for the shielded sub-band from the UE, and if the sub-band signal metric is above a threshold, then the base station authorizes use of the shielded sub-band for the UE. The base station receives a communication request for the UE, and in response, transfers another sub-band null request to the adjacent base station and exchanges wireless data over the shielded sub-band with the UE.

Abstract: A wireless access point serves dynamic direction-of-arrival reception. An access point radio wirelessly receives a wireless signal that transports time-domain data. Access point circuitry determines uplink utilization for the access point radio. The circuitry transforms the time-domain data into frequency-domain data. The circuitry filters the frequency-domain data for one direction-of-arrival responsive to the uplink utilization. The circuitry synthesizes the time-domain data from the filtered frequency-domain data. The radio wirelessly receives another wireless signal that transports additional time-domain data. The circuitry determines a higher uplink utilization for the access point radio. The circuitry transforms the additional time-domain data into additional frequency-domain data. The circuitry filters the additional frequency-domain data for multiple directions-of-arrival responsive to the higher uplink utilization. The circuitry synthesizes the additional time-domain data from the filtered additional frequency-domain data.

Abstract: The technology described herein enhances the operation of a wireless repeater system to set an Automatic Gain Control (AGC) timer. In one implementation, the wireless repeater wirelessly receives a receive data signal having a receive energy level. The wireless repeater periodically processes the receive energy level per the AGC timer to calculate an AGC amount. The wireless repeater also applies the AGC amount to the received data signal to generate a transmit data signal, and wirelessly transfers the transmit data signal. The wireless RF repeater determines an energy fluctuation in the receive data signal, and when the energy fluctuation in the receive data signal exceeds a fluctuation threshold, the wireless repeater decreases the AGC timer.

Abstract: A wireless base station locates User Equipment (UE) that is served by a wireless repeater chain that is served by the wireless base station. The wireless base station maintains a data structure that indicates geographic locations for wireless repeaters in the wireless repeater chain. The wireless base station wirelessly exchanges user data with the wireless repeater chain responsive to the UE exchanging the user data with one of the wireless repeaters in the wireless repeater chain. The wireless base station determines repeater hops in the wireless repeater chain between the wireless base station and the UE. The wireless base station determines the wireless repeater serving the UE based on the repeater hops. The wireless base station indicates a geographic location in the data structure for the wireless repeater serving the UE.

Abstract: Radio circuitry wirelessly serves User Equipment (UE) with dynamic direction-of-arrival reception. Control circuitry determines a primary direction-of-arrival for a user signal and configures a digital filter for the primary direction-of-arrival. Detection circuitry filters the user signal with the digital filter configured for the primary direction-of-arrival and recovers user data from the user signal. The control circuitry determines increased radio noise and/or uplink utilization reconfigures the digital filter for multiple directions-of-arrival. The detection circuitry filters a subsequent user signal with the digital filter configured for the multiple directions-of-arrival and recovers additional user data from the subsequent user signal.

Abstract: A wireless access point controls Carrier Aggregation (CA) based on Multi-User Multiple Input Multiple Output (MU-MIMO). Baseband circuitry selects CA User Equipment (UEs) based on Radio Frequency (RF) signal strengths for the CA UEs exceeding a CA RF threshold. Transceiver circuitry wirelessly transfers user data to the selected CA UEs over CA links. The transceiver circuitry wirelessly transfers user data to MU-MIMO UEs over MU-MIMO links. The baseband circuitry adjusts the CA RF threshold based on changing MU-MIMO UE loading. The baseband circuitry re-selects the CA UEs based on their current RF signal strengths exceeding the adjusted CA RF threshold. The transceiver circuitry wirelessly transfers user data to the re-selected CA UEs using new CA links.
