Signal reception method and apparatus for a UE in an idle-state, storage medium, and a terminal. The method includes: monitoring signal quality of a serving cell; and determining and receiving system information matching the signal quality based on the signal quality.

Certain aspects of the present disclosure provide an apparatus for wireless communications. The apparatus generally includes a processing system configured to generate a frame for triggering transmission of a plurality of data units from a plurality of wireless nodes, a first interface configured to output the frame for transmission to the plurality of wireless nodes, and a second interface configured to obtain the plurality of data units after outputting the frame for transmission, wherein the plurality of data units have different lengths.

A client device is configured to communicate with an access point over a wireless network, exchanging data with the access point over a selected communication channel. The client device stores an identifier of the selected communication channel. After the wireless connection to the access point has ended, the client device initiates a process to reconnect to the access point over the selected communication channel using the stored identifier.

Techniques for dynamically adjusting Connected Mode Discontinuous Reception (CDRX) parameters are discussed herein. For example, a base station may receive information associated with downlink data to be sent to a user equipment (UE) and/or information associated with the UE itself. The base station may adjust CDRX parameters to be implemented on the UE based on the received information in order to maximize performance of the UE. In some examples, the base station may adjust CDRX parameters based on a traffic type (e.g., voice traffic, video traffic, data traffic, etc.) associated with the downlink data, UE state parameters associated with the UE, and/or Received Signal Strength Indicator (RSSI) data associated with the UE.

A device including one or more processors configured to: determine a disconnection margin value based on: a current transmission operation state including one or more transmission control parameters, and a current transmission rate; receive a power back-off (PBO) request including a PBO value; perform a comparison of the PBO value to the disconnection margin value; and determine whether to apply a PBO according to the PBO request based on the comparison.

A method and apparatus are provided for determining, by a wireless power transmitter, whether a wireless power receiver is removed from a wireless power network managed by the wireless power transmitter. The method includes transmitting a command signal to report power information of the wireless power receiver at stated periods; determining whether a report signal corresponding to the command signal is received from the wireless power receiver; and determining that the wireless power receiver is removed from the wireless power network, if the report signal is not received after transmitting the command signal a predetermined number of times at the stated periods.

A method and apparatus are provided for controlling wireless power in a wireless power network managed by a wireless power transmitter. The control method includes registering a wireless power receiver to a wireless power network corresponding to the wireless power transmitter; applying a charging power for charging the wireless power receiver to a resonator of the wireless power transmitter; detecting a change of magnitude of power applied to the resonator; detecting that a communication unit of the wireless power transmitter fails to receive a communication signal from the wireless power receiver a predetermined time; and in response to detecting the change of the magnitude of power applied to the resonator and that the communication unit fails to receive the communication signal from the wireless power receiver in the predetermined time, removing the wireless power receiver from the wireless power network.

Techniques for wireless component monitoring are described herein. The techniques may include entering a low power mode to associate a radio frequency identification (RFID) component with a patient monitoring device within a first range. The techniques also include entering a high power mode wherein the patient monitoring device is to detect the RFID component within a second range of the patient monitoring device, wherein the second range is larger than the first range.
