Abstract: In an example method, a donor base station determines that an air interface, over which the donor base station serves a relay-UE and plurality of second UEs, is threshold highly congested and that a relay base station is serving a threshold high number of first UEs. The relay base station is coupled to a relay-UE that provides wireless connectivity for the relay base station and that is served by the donor base station. Responsive to at least the determining that the air interface is threshold highly congested and that the relay base station is serving a threshold high number of first UEs, the donor base station (i) selects one or more of the plurality of second UEs and (ii) hands over the selected one or more second UEs to another base station other than the donor base station.

Abstract: Disclosed is a method and system for use of orthogonal coding to manage control channel load. Based on evaluation of downlink air interface load, a base station dynamically toggles use of orthogonal coding of downlink control information (DCI) messages for transmission on a downlink control channel. When downlink load is high, the base station may responsively operate in a state in which the base station orthogonally codes DCI messages to facilitate transmitting multiple DCI messages per set of resource elements on the downlink control channel, possibly boosting transmission power in those resource elements to help facilitate successful transmission. Whereas, when downlink load is not high, the base station may responsively operate in a state in which the base station does not orthogonally code DCI messages and thus sends just one DCI message per set of resource elements.

Abstract: Disclosed are methods and systems for adjusting allocation of uplink (UL) and downlink (DL) air interface resources to user equipment devices (UEs) in a wireless communication system configured for dynamic allocation of relative amounts UL and DL time division duplex (TDD) air interface resources. The wireless communication system may determine usage demand for UL air interface resources relative to DL air interface resources as a function of time of day. Then, based on the usage demand, a schedule may be created for assigning a ratio of UL TDD allocation to DL TDD allocation. Finally, dynamic TDD allocation may be applied to set relative amounts of UL and DL air interface time for UEs served by the wireless communication system according to the schedule, instead of applying unscheduled dynamic TDD allocation of relative amounts of UL and DL air interface time.

Abstract: Disclosed is a method and system for enabling user equipment devices (UEs) to apply less attenuation than may be specified more generally for UEs served by a base station of a wireless service provider. The base station may operate on a carrier band, serving UEs that are subscribers of the wireless service provider as well as UEs roaming in the base station's coverage area from another service provider. To avoid uplink transmission power leakage across the edges of the carrier band, the base station may broadcast a message to all the UEs notifying them to attenuate their respective transmission levels. In response, a UE may determine whether or not it is roaming to a wireless communication network of a different service provider. If the UE determines that it is not roaming, it may then attenuate its uplink transmission power by less than an amount indicated by the message.

Abstract: Disclosed are methods and systems for requesting a UE to forgo handover to a congested neighbor. In particular, a wireless communication system may serve the UE over an air interface connection between the UE and the first base station. While serving the UE, the wireless communication system may receive from the UE a handover request requesting a handover of the UE from the first base station to a second base station. In response to receiving from the UE the handover request, the wireless communication system may determine that the second base station is threshold congested, and, responsive to the determining, (i) deny the handover request and (ii) send to the UE a command for the UE to withhold transmission of further requests for handover of the UE from the first base station to the second base station.

Abstract: A downlink resource block in an orthogonal frequency division multiplexing (OFDM) communication system can be shared among multiple wireless communication devices (WCDs) by assigning one or more orthogonal codes to each WCD. To transmit data to the WCDs using the downlink resource block, a base station may receive a data stream that includes respective data for each of the WCDs and encode each WCD's respective data with a respective orthogonal code assigned to that WCD to generate an encoded data stream. An OFDM transmitter in the base station may receive the encoded data stream and transmit the encoded data in the form of OFDM symbols in the downlink resource block. A WCD can receive the downlink resource block, recover the encoded data from the OFDM symbols, and use the one or more orthogonal codes assigned to it to recover the data for that WCD from the encoded data.

Abstract: A method for coordinated control-channel signaling by first and second access nodes that provide overlapping coverage on respective first and second carriers that overlap in frequency with each other. The first access node configures a first enhanced physical downlink control channel (ePDCCH) on the first carrier and the second access node configures a second ePDCCH on the second carrier, with the first ePDCCH and second ePDCCH overlapping in frequency and time with each other, for efficient use of PDSCH capacity of the two carriers. In an implementation, the two access nodes could operate according to different radio access technologies. For instance, the first access node could provide LTE service, and the second access node could provide 5G NR service.
