Abstract: A first access node that is operating on a first TDD carrier having a first TDD configuration will determine that a second TDD carrier on which a proximate second access node is operating has a different, second TDD configuration, such that there is at least one time interval in which the first TDD carrier is downlink concurrently with the second TDD carrier being uplink. In response to at least this determination, the first access node will then transition to a mode in which, during the time interval, the first access node will operate with reduced transmission power on a frequency portion of the first TDD carrier that is closest in frequency to the second TDD carrier. Further, the first access node could allocate the lower-transmission-power frequency portion for use in transmission to served devices deemed to be in at least predefined threshold high quality coverage of the first access node.

Abstract: A method and system for concurrent transmission of (i) a first bit sequence from a first access node to a UE and (ii) a second bit sequence from a second access node to the UE, when the first access node serves the UE on a first carrier according to a first radio access technology (RAT), the second access node serves the UE on a second carrier according to a second RAT, and the first and second carriers overlap in frequency. Per the disclosure, the access nodes could orthogonally encode their respective bit sequences and could concurrently transmit the resulting encoded bit sequences to the UE on the same frequency as each other.

Abstract: When a first base station is serving a wireless client device (WCD), the first base station provides the WCD with a copy of the WCD context information that the first base station maintains for serving the WCD. When the WCD then experiences a radio-link failure and connects with the second base station, the WCD will forward the provided WCD context information to the second base station, for use by the second base station as a basis to serve the WCD. This process of transferring the context information through the WCD from the old base station to the new base station could help to avoid the need for the second base station to engage in direct context-transfer signaling with the first base station, which could be especially useful in a scenario where the base stations are unable to engage in that direct transfer.

Abstract: A method and a system for concurrently transmitting from an antenna a first sequence of data from a first access node and a second sequence of data from a second access node. An example method includes orthogonally encoding the first and second sequences, including encoding the first sequence with a first binary code to produce a first encoded sequence and encoding the second sequence with a second binary code to produce a second encoded sequence, combining the first encoded sequence and the second encoded sequence to produce a combined encoded sequence, and transmitting the combined encoded sequence from the antenna, with transmitting the combined encoded sequence from the antenna including engaging in a first transmission of the combined encoded sequence from the antenna and engaging in a second transmission of the combined encoded sequence from the same antenna with a phase delay compared with the first transmission.

Abstract: A computing system will detect when a UE engaged in a voice call hands over from a lower frequency coverage area to a higher frequency coverage area where it is raining, and the computing system will responsively take action to help improve the UE's communication quality, in an effort to help minimize the extent to which voice call quality will degrade as a result of the transition to the higher frequency where it is raining. In particular, per the disclosure, the computing system could respond to this scenario by causing the target base station to use a more robust wireless transmission mode than the source base station was using to serve the UE.

Abstract: A method for controlling configuration of an air interface between an access node and at least one user equipment device (UE), where the air interface is divided over time into frames and the frames are further divided at least into subframes, where the air interface operates in accordance with a time-division-duplex (TDD) configuration that defines at least a number of uplink subframes per frame for communication over the air interface. An example method includes (i) detecting at least a threshold high rate of uplink voice muting on the air interface, and (ii) responsive to at least the detecting, changing the TDD configuration to increase the number of uplink subframes per frame over the air interface.

Abstract: A method and system for triggering RF reconfiguration of wireless communication system. RSRP-SINR pairs determined respectively for locations in a region of interest are mapped to predicted MOS of voice communication per location, using a prediction engine trained based on actual correlated measurements of RSRP, SINR, and MOS. Locations having threshold low MOS and threshold low RSRP but not threshold low SINR are identified and clustered to identify an area where coverage strength should be increased in an effort to help improve voice-call quality. And locations having threshold low MOS and threshold low SINR but not threshold low RSRP are identified and clustered to identify an area where interference should be reduced in an effort to help improve voice-call quality. An engineering trouble ticket or other signal could then be generated to trigger associated network reconfiguration.

Abstract: When access nodes provide collocated service on overlapping carriers with different subcarrier spacing than each other, at least one of the access nodes could be configured to cluster its respective allocation of air-interface resources at an end of the frequency-overlap region, and a single guard band could then separate that clustered resource allocation from the remainder of the frequency-overlap region in which the other access node could allocate resources. In an example implementation for instance, the access nodes could be configured to cluster their respective concurrent allocation of resources at different respective ends of the frequency-overlap region so as to help maximize frequency width between transmission in the frequency-overlap region on one of the carriers with one subcarrier spacing and transmission in the frequency-overlap region on the other carrier with the other subcarrier spacing.
