A transmitter of an electronic device may include one or more intermediate frequency stage circuitries. Processing circuitry may select one or more intermediate frequency stage circuitries of the transmitter that output one or more intermediate frequency signals that cause interference with a signal received by a receiver of the electronic device. The processing circuitry may adjust settings of the one or more intermediate frequency stage circuitries to reduce interference with the signal received by the receiver and store the settings. Subsequently, the processing circuitry may receive an indication of an operational mode of the receiver and apply the settings to the one or more intermediate frequency stage circuitries based on the indication.

Systems and methods to reduce interference in a radio frequency device

Techniques described herein are directed toward smart external interference detection and avoidance. An example method includes determining a first received signal strength indicator (RSSI) value of a received first signal across a radio band, wherein the first RSSI value is based at least in part on a second signal transmitted by an interfering device. The first received RSSI value is compared with a threshold value. A first gain adjustment value is determined for a receiver chain of the first computing device and a second gain adjustment value of a transmitter chain based at least in part on the comparison. A first gain of a first amplifier of the receiver chain is adjusted based at least in part on the first gain adjustment value. A second gain of a second amplifier of the transmitter chain is adjusted based at least in part on the second gain adjustment value.

Smart external interference detection and avoidance for wireless communication

Embodiments relate to an integrated circuit of an electronic device that coordinates activities with another integrated circuit of the electronic device. The integrated circuit includes an interface circuit and a processor circuit. The interface circuit communicates over a multi-drop bus connected to multiple electronic components. The processor circuit receives an authorization request from the integrated circuit via the interface circuit and the multi-drop bus. The received authorization request relates to authorization to perform an activity on the other integrated circuit. In response to receiving the authorization request, the processor circuit determines whether the other integrated circuit is authorized to execute the activity. In response to determining that the other integrated circuit is authorized to execute the activity, the processor circuit sends, to the other integrated circuit over a configurable direct connection, an authorization signal authorizing the other integrated circuit to execute the activity.

System for link management between multiple communication chips

Circuits, methods, and apparatus that can allow chipsets in an electronic device to share information such that they can more efficiently utilize resources that are available in the electronic device. One example can provide a bus that is shared by three or more chipsets in an electronic device. This shared bus can be used by the chipsets in the electronic device to communicate and negotiate for the utilization of resources of the electronic device.

Bus protocol for multiple chipsets

An electronic device that selectively provides a trigger frame is described. During operation, the electronic device may receive a frame from a recipient electronic device, where the frame includes information that specifies a maximum uplink multi-user transmit duration of the recipient electronic device. Moreover, the electronic device may selectively provide the trigger frame to the recipient electronic device that specifies an uplink OFDMA frame or an uplink MIMO frame associated with the recipient electronic device. The trigger frame may be selectively provided when a transmit time corresponding to the uplink OFDMA frame or the uplink MIMO frame is less than or equal to the maximum uplink multi-user transmit duration.

Specifying a transmission-time limit for uplink multi-user communication

An interface circuit in an electronic device (such as an access point) may request a channel status in order to specify a subset of one or more frequency sub-bands. During operation, the interface circuit may provide at least a frame to the recipient electronic device, where the frame requests the channel status for the one or more frequency sub-bands. Then, the electronic device may receive one or more measurement results from the recipient electronic device that specify the subset of the one or more frequency sub-bands (such as one or more RUs) that are not to be used when communicating with the recipient electronic device.

Forbidden-resource-unit indication for coexisting communication

Methods, systems and apparatus for a user equipment to mitigate interference in a wireless charging state. The user equipment may determine when the user equipment enters a wireless charging state and, when the user equipment enters the wireless charging state, activate an interference mitigation. The user equipment may further determine when the UE exits the wireless charging state and, when the user equipment exits the wireless charging state, deactivate the interference mitigation.

Methods, systems and apparatus for mitigating wireless connection degradation due to wireless charging

Various mechanisms for paging link-budget-limited (LBL) devices are disclosed, including: (1) transmitting paging message with non-conventional paging identifier; (2) transmitting paging message(s) with increased power; (3) repeating transmission of paging message to support combining at receiver. Various mechanisms for UE device to signal LBL status are disclosed, including, transmitting status flag or special value of DRX cycle to network node as part of tracking area update and/or attach request. The network node informs a base station of the device's LBL status as part of a paging message. (The network node may, e.g., assign an S-RNTI to the LBL device from a reserved subset of S-RNTI space.) The base station invokes a paging enhancement mechanism when paging an LBL device. Alternatively, the base station may page UE devices without knowledge of LBL status, e.g., by counting paging attempts for a given UE, and boosting power after the Npaging attempt.

Paging mechanisms for link-budget-limited user devices

A device, system, and method estimate a link budget on a companion device. The method is performed at a first device connecting to a second device over a first connection and a network over a second connection, the second device connecting to the network over a third connection. The method includes receiving initiating data from the second device based on radio conditions associated with the third connection. The method includes, when the first device disconnects from the second device and establishes the second connection, determining an initial network metric value based on the initiating data that is used to estimate radio conditions associated with the second connection. The method includes selecting a data exchange mode of the first device based on the initial network metric value which is used until a further network metric is determined by the first device.

Link budget estimation on companion device

A device sets an activity mode for a cellular connection. A method to set the activity mode is performed at a device located with a user that is configured to establish a network connection to a network. The method includes determining a status of the user, the status indicating an activity state or a non-activity state of the user. The method includes, when the status indicates the activity state, activating an activity mode on the device that restricts select types of mobile originating data traffic.

Activity mode for a cellular connection

Systems, methods, and computer-readable media for managing or classifying movement states of an electronic device are provided that may utilize communications circuitry data from one or more communications circuitries when determining a current or future movement state of an electronic device.

Management of movement states of an electronic device using communications circuitry data

Described is a user equipment (UE) that is connected to a network component, the user equipment and the network component configured with a carrier aggregation functionality. The UE performs a method that includes determining a primary component carrier and at least one secondary component carrier associated with the carrier aggregation functionality of the user equipment, determining a component carrier quality measurement (CQM) metric for each of the component carriers, when an uplink data packet is capable of being transmitted over the secondary component carrier, selecting one of the primary component carrier and the at least one secondary component carrier based on the CQM metrics, generating measurement data indicative of the selected component carrier to increase a probability to transmit the uplink data packet over the selected component carrier and transmitting the measurement data to the network component.
