Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may update a noise estimation (e.g., a noise covariance matrix, a log likelihood ratio (LLR) scaling, or both) for communications with a serving base station to account for interference from a neighboring base station operating according to a different radio access technology (RAT). For example, the UE may identify a transmission status of a base station operating according to a first RAT, such as long term evolution (LTE), that shares a radio frequency spectrum with a serving base station operating according to a second RAT, such as new radio (NR). The UE may measure the interference from the LTE base station and may update a noise estimation according to the measured interference. The UE and the serving base station may communicate based on the updated noise estimation.

Abstract: When communications of a single radio access technology (RAT), or different radio access technologies in a proximate communication spectrum are operating at the same time, potential interference between devices may occur. To reduce the interference, the time division duplex (TDD) configuration of one or more conflicting device may be altered. For example, at the edge of a communication region, TDD configurations used by edge base stations to communicate with mobile devices may be set to reduce interference. As another example, communications of a first device may be altered so the first device schedules uplink communications when a second device also has uplink communications scheduled. Other configurations may also be implemented.

Abstract: The present disclosure includes systems and methods for operating a wireless communication system in multiple modes. The system is configured in a first mode when a transmission interference in a receiver of a wireless device is below a first threshold. The system is configured in one or more intermediate modes when the transmission interference is above the first threshold and below a second threshold. The system is configured in a second mode when the transmission interference is above the second threshold. The one or more intermediate modes activate interference management processes and the wireless device transmits data and receives data simultaneously. In some embodiments, transmission interference may be based on an SINR measurement.

Abstract: Various embodiments enable a multi-active mobile communication device to mitigate (manage) interference by a frequency band used by a first subscription with the frequency band used by a second subscription. The device processor may generate modified power measurements for one or more frequency bands of a first subscription and use the modified power measurement(s) to cause the first subscription to switch from the frequency band that interferes with the frequency band of the second subscription. The modified power measurement may be a decreased power measurement of the first frequency band and/or an increased power measurement of a second frequency band that does not interfere with the frequency band of the second subscription. As a result, various embodiments may mitigate or otherwise manage the impact of coexistence interference between the first and second subscriptions of a multi-active mobile communication device without limiting capabilities of the device or changes to the network.

Abstract: A UE with a limited number of antennas may support multiple radio access technologies (RATS). In some instances, the UE may configure a shared antenna for use by a wireless local area network (WLAN) radio access technology (RAT) or a cellular RAT. The UE may also allocate the shared antenna to the WLAN RAT when the cellular RAT is active based at least in part on an operating condition of the WLAN RAT and/or the cellular RAT.

Abstract: Aspects of the present disclosure provide techniques for the user equipment (UE) to select a power management mode from a plurality of power management modes supported by the UE based on decoding of a portion of the downlink subframe. For example, when the UE receives a subframe from a base station, the UE may decode a control channel region of the subframe to determine whether the subframe includes a channel grant allocated to the UE. If no channel grant is included in the subframe, the UE may select a power management mode for the UE from the plurality of power management modes supported by the UE that maximizes the UE's sleep opportunities while balancing the deficient performance costs.

Abstract: Optimizing multiflow performance and priority across UEs and networks including receive antenna selection at the UEs, CSI measurement and reporting, and scheduling for multiflow operation. The techniques may evaluate channel conditions for a UE for multiple access points and different combinations of antennas and determine how the UE should feedback CSI for transmissions from the multiple access points. The disclosed techniques also include techniques for scheduling transmissions from the multiple access points using the CSI information to optimize multiflow performance and priority across UEs and networks. Various scheduling modes use feedback from UEs including the maximum supported rates for each link and/or rates based on the maximum sum capacity of the links used concurrently. The scheduler may maintain separate priority lists for each access point or a single priority list across both access points. The techniques may be used for multiflow operation using LTE and WLAN links.
