Some aspects of this disclosure relate to apparatuses and methods for implementing cell search based on battery conditions of a user equipment (UE). For example, some aspects of this disclosure relate to a UE. The UE includes a transceiver configured to enable wireless communication with a base station and a processor communicatively coupled to the transceiver. The processor is configured to perform a cell search cycle in response to a determination that a connection with the base station has been lost. In response to a determination that UE is in a no-service mode or in a limited-service mode after the cell search cycle, the processor further configures a sleep timer value based at least on one of a charge level of a battery of the UE or a capacity level of the battery. The processor further performs a second cell search cycle after the configured sleep timer value.

Cell search based on user equipment (UE) battery condition

User equipment includes a first antenna, a second antenna, a first transceiver coupled to the first antenna, a second transceiver coupled to the second antenna, and processing circuitry communicatively coupled to the first transceiver and the second transceiver. The first transceiver receives or transmits a first signal via the first antenna, and the second transceiver receives or transmits a second signal via the second antenna. The processing circuitry receives an indication that a signal characteristic of the first signal is less than a first threshold, and decreases power to the first antenna, the first receiver, or both, based on the signal characteristic of the first signal being less than the first threshold.

Dynamic activation of network hardware based on real-time conditions

Disclosed are embodiments for reducing likelihood of selecting a cell identified by a Radio Access Network (RAN) Notification Area ID (RNA ID) that is different from that identifying a last or current serving cell so as to avoid an RNA update procedure; reducing Random Access Channel (RACH) transmissions for an RNA update procedure and a mobile originated (MO) data transmission in response to a Radio Resource Control (RRC) triggered RNA update procedure; and selecting a band or beam in a multi-band/beam cellular system that improves RACH efficiency.

Reducing RNA update procedures and improving RACH efficiency

Apparatuses, systems, and methods for RACH procedures to avoid excessive handover/secondary cell group failures. A base station may declare a handover and/or secondary cell group (SCG) failure and may determine that a failure threshold has been met. The base station may perform a remedial action in response to meeting the failure threshold. The failure threshold may be multi-dimensional, where a first dimension is associated with a number of handover/SCG failures and where a second dimension is associated with a time period in which the number of handover/SCG failures occurred. Further, a third dimension may be associated with a UE mobility state and a fourth dimension may be associated with whether the UE is using FR1 or FR2. The remedial action in response to meeting the failure threshold may include the base station suspending transmission of measurement object configurations for a specified period of time.

5G NR efficient FR1/FR2 operation

In order to facilitate communication in a wireless network, an accessibility issue in the wireless network may be detected. For example, if an electronic device is near the boundary between two adjacent cells in the cellular-telephone network, the signal power of signals from a current cell or connection may decrease. Concurrently, the maximum transmit power of the electronic device may be constrained by a thermal limit of the electronic device. When this occurs, the connection may be lost unless remedial action is taken. Therefore, in response to this condition, the electronic device may temporarily increase the maximum transmit power to allow the electronic device to communicate with the cellular-telephone network so that the connection may be transitioned to another cell or connection. In this way, the communication technique may restore the communication performance and avoid a dropped call, which will improve the user experience and customer satisfaction.
