Abstract: Disclosed are methods and systems to facilitate management of carriers to help ensure QoS for single-carrier UEs. In particular, a base station may serve one or more first user equipment devices (UEs) on just a first carrier. While doing so, the base station may determine that each of the one or more first UEs being served on just the first carrier is receiving threshold low quality of service from the base station on the first carrier. Responsive to this determining, the base station may (i) select one or more second UEs based on the one or more second UEs being served by the base station on both the first carrier and one or more other carriers and (ii) discontinue serving each selected second UE on the first carrier while continuing to serve each selected second UE on one or more other carriers.

Abstract: A method and system for controlling wireless communication over an air interface between a base station and a user equipment device (UE) served by the base station. In examples, the base station is configured to use a particular modulation and coding scheme (MCS) to transmit downlink control signals over the air interface to the UE without the base station beamforming the downlink control signals to the UE. Responsive to the base station determining that the UE is experiencing threshold poor RF conditions on the air interface, the base station reconfigures itself to beamform downlink control signals to the UE. And, given that the base station is reconfigured to beamform downlink control signals to the UE, the base station further reconfigures itself to use a higher-order MCS to transmit downlink control signals to the UE.

Abstract: A method and system for managing carriers on which a base station provides service to a user equipment device (UE), based on consideration of latency. A base station that is arranged to operate on a plurality of carriers may, while serving a UE on a set of one or more carriers of the plurality, select, from at least two other carriers of the plurality, an additional carrier to add to the set of one or more carriers on which the base station serves the UE, and may make the selection based a latency on the selected carrier. In response to selecting the additional carrier, the base station may add the selected carrier to the set of one or more carriers on which the base station serves the UE, and may then serve the UE on the set of one or more carriers including the selected carrier.

Abstract: A voice coding rate is selected for a voice call involving a user equipment (UE) device based on an air interface efficiency of the base station serving the UE device. The air interface efficiency of the base station is determined based on at least one of (i) a beamforming capability of the base station, (ii) a multi-user multiple-input multiple-output (MU-MIMO) capability of the base station, or (iii) an antenna configuration of the base station. The voice coding rate could be selected by either the UE device or by the base station. The UE device transmits to the base station during the voice call one or more voice frames that convey voice data coded at the selected voice coding rate. During the voice call, a new air interface efficiency may be determined, and a new voice coding rate may be selected based on the new air interface efficiency.

Abstract: Disclosed is a method and system for controlling air interface communication in a wireless communication system that supports multiple TDD configurations. In a disclosed example, a base station's cell is initially configured to operate with a particular TDD configuration. The base station then detects a trigger to reduce uplink latency in the cell, such as by detecting a threshold number of devices being served with latency-sensitive communication such as voice-over-packet communication. And the base station responsively reconfigures the cell to operate with a different TDD configuration having lower uplink latency, where uplink latency of each TDD configuration is based average wait to uplink subframe of the TDD configuration.

Abstract: Disclosed is method and apparatus to help reduce PRACH interference. In accordance with the disclosure, when a first base station determines that there is a threshold level of interference from a second base station, the first base station transmits to the second base station a directive that causes the second base station to reduce PUSCH transmission in PUSCH resources that are coincident in frequency with the first base station's PRACH. In a scenario where two base stations provide overlapping coverage and operate on the same frequency as each other, and where coverage of the second base station may interfere with coverage of the first base station, this process may thereby help to minimize or eliminate interference that PUSCH communication in the second base station's coverage area would have on PRACH communication in the first base station's coverage area.

Abstract: According to aspects of the disclosure, a method and system are provided for managing signaling in a wireless communication network. In accordance with the disclosure, a base station serves a plurality of user equipment devices (UEs) via an air interface extending between the base station and the UEs. The base station also receives, on an uplink of the air interface, a report from each UE indicating channel state information (CSI). The base station periodically receives the report from each UE according to a CSI reporting rate specified by the base station for the UE. The base station may determine that a level of loading on the uplink is greater than a threshold load value. Responsive to such determination, the base station selects a subset of the plurality of UEs and reduces the CSI reporting rate for the selected subset of the plurality of UEs to reduce congestion on the uplink.

Abstract: Carrier aggregation may occur in wireless networks when multiple carriers from either contiguous frequency bands or non-contiguous frequency bands are aggregated together as component carriers. Wireless computing devices (WCDs) may use these aggregated component carriers as a single, logical channel for wireless communication. Such a WCD may determine that an amount of carrier aggregation used by a wireless interface of the WCD has increased. The WCD may receive data packets from a correspondent device by way of the wireless interface, and the WCD may transmit, in response to receiving the data packets, acknowledgment packets to the correspondent device by way of the wireless interface. Possibly based on the amount of carrier aggregation increasing, the WCD may reduce an extent of the acknowledgment packets transmitted to the correspondent device.
