The performance and ease of management of wireless communications environments is improved by a mechanism that enables access points (APs) to perform automatic channel selection. A wireless network can therefore include multiple APs, each of which will automatically choose a channel such that channel usage is optimized. Furthermore, APs can perform automatic power adjustment so that multiple APs can operate on the same channel while minimizing interference with each other. Wireless stations are load balanced across APs so that user bandwidth is optimized. A movement detection scheme provides seamless roaming of stations between APs.

A method for wireless communication is described. The method includes receiving a silent indication (SID) start message from a modem at a Bluetooth (BT) module when the modem detects a silent period in a voice call. The method also includes sending the SID start message from the BT module to a remote BT device. The method further includes disabling a BT transmitter during the silent period based on the SID start message received from the modem.

A radio base station (1), which is to be pre-blockaded, transmits a pre-blockade initiate notification to radio base stations (2A-2F) neighboring the radio base station (1). Further, the radio base station (1) reduces the transmission power thereof at a predetermined reduction rate at a initiation time of the pre-blockade. Meanwhile, each of the radio base stations (2A-2F) receives the pre-blockade initiate notification and increases the transmission power at a predetermined increase rate at the initiation time of the pre-blockade, the absolute value of predetermined increase rate being equal to that of the predetermined reduction rate at the radio base station (1).

Techniques to cause a point-to-point link between system components to engage in a negotiation process that may lead to the link transitioning from an active state in which data may be transmitted between system components to a low power state where data may not be transmitted. The negotiation process may occur between each pair of nodes within an electronic system that are interconnected via point-to-point link. The negotiation may ensure that there are no pending transactions or transactions that may occur within an upcoming period of time. Through this negotiation each component acknowledges and agrees to transition the link to the low power state.

The invention relates to a method and an arrangement for reducing power consumption of a receiver in a mobile communication network comprising a sender transmitting packet data on a downlink channel to one or more receivers over a radio interface. Inactive time instants and listening time instants are defined according to provided rules. The receiver is arranged to listen for information from the sender during the listening time instants and to sleep during the inactive time instants. Thus, less power will be consumed during the inactive time instants.

Disclosed are operation method of station in wireless local area network. An operation method comprises setting transmission power of a frame; setting a clear channel assessment (CCA) threshold based on a difference between the set transmission power and a default value of the transmission power; and performing a CCA operation based on the set CCA threshold. Therefore, performance of WLAN can be enhanced.

A user equipment (UE) may enter a dormant state for a secondary cell group (SCG) of a secondary network (SN) having a primary serving cell (PSCell). The UE may maintain an uplink parameter set for the PSCell while the SCG is dormant for the UE. For example, the UE may receive a parameter change message from either the SN or a master network (MN) and transmit a parameter change acknowledgment to either the SN or the MN. The UE may transmit a periodic measurement report for at least the PSCell to the PSCell of the SN based on the uplink parameter set.

An electronic device and a power control method of an electronic device are provided. The electronic device may include: a communication circuit including a first circuit configured to perform first communication and a second circuit configured to perform second communication; a processor electrically connected to the communication circuit; and a memory electrically connected to the processor, wherein, the memory stores instructions that, when executed, cause the processor to perform operations comprising: controlling the first circuit to operate according to a first power control mode associated with the first communication, and controlling the second circuit to operate according to a second power control mode associated with the second communication when the first communication and the second communication are concurrently performed through the first circuit and the second circuit; identifying a first sleep period during which the first circuit operates in a sleep mode according to the first power control mode, and a second sleep period during which the second circuit operates in the sleep mode according to the second power control mode; and controlling the communication circuit to operate in a deep sleep mode in which the communication circuit operates with power that is less than or equal to a predetermined power in a period where the first sleep period and the second sleep period coincide.

A wireless device receives a radio resource control (RRC) release message indicating a small data transmission (SDT) time window for an SDT in an RRC inactive state. The wireless device transmits, during the SDT time window, an initial uplink transmission using a first power control adjustment (PCA) state being reset to zero. The wireless device transmits, using a second PCA state, a second uplink transmission. In response to the second uplink transmission being subsequent to the initial uplink transmission during the SDT time window, the second PCA state is based on the first PCA state and one or more transmit power control command values received during the SDT time window.

A method performed by a network node for managing power of Cell Reference Symbols, CRS, wherein the network node operates one or more cells and the network node is configured to transmit the CRS in a first power mode. When the network node identifies a first cell which is not actively serving any UEs, which cell is also referred to as an empty cell, the network node reduces the power of the CRS in the first cell in relation to the first power mode. By reducing the power of the CRS, the overall interference of the CRS from the empty cell is reduced, thereby enhancing the performance in cells actively serving UEs.
