Abstract: During the transition period from 4G and long-term evolution (LTE) to 5G technology, for 5G capable user equipment (UE), it is preferred to utilize non-standalone (NSA) cells that support 5G technology rather than LTE only cells. To enable such preference, a fingerprint database recording known neighboring NSA cells to LTE only cells and a flag for identifying NSA cells in the acquisition database of the UE can be used to prioritize searching for NSA cells on startup and to expedite reselection to an NSA cell when camping on LTE only cells. To avoid excess battery drain when camping on LTE only cells since searching for cells consumes significant power of the UE, a series of timers and a counter can be used to disable the NSA preferred feature if an NSA cell is not found after a reasonable search while camping on the LTE only cell.

Abstract: Communication with state-switching control is disclosed. In one example, a communication device includes a state-switching control circuit that controls switching between a first state in which synchronization for communicating with a partner device is established, a second state in which the communication is started after establishing the synchronization, a third state in which the communication is intermittently stopped, and a fourth state in which synchronization is reestablished when restarting the communication. A first communication control circuit repeats an operation of continuously transmitting a first signal to the partner device in the fourth state, and a second communication control circuit transmits, upon receiving a second signal, a third signal synchronized with the second signal to the partner device, in which the state-switching control circuit switches, where the second communication control circuit transmits the third signal, a state from the fourth state to the first state.

Abstract: Methods, systems, and devices for wireless communications are described. Different periodicities may be dynamically selected when monitoring and transmitting signaling used for link management, where respective periodicities may be based on the quality of the link between devices. For instance, a first wireless device may use a first monitoring periodicity to monitor for signals transmitted from another wireless device. Upon determining that a link condition has changed (e.g., decreased or reached a threshold), the first wireless device may decrease its monitoring periodicity (and increase monitoring frequency) to detect signals transmitted by the other wireless device more frequently. In such cases, the other wireless device may likewise transmit its measurement signals more often (e.g., in accordance with a second periodicity) based on the link quality. The adjusted monitoring and transmission periodicities may provide additional occasions for the wireless device to detect signals from another device.

Abstract: The described technology is generally directed towards interference avoidance for cellular networks. A controller can estimate intercell interference and provide recommendations of preferred time slots that can be used by cell schedulers to avoid intercell interference. The controller can leverage sporadic traffic of neighboring cells by identifying time slots at which traffic demand likely to result in intercell interference. The controller can then guide schedulers at cells to send data in a manner that mitigates intercell interference.
