Systems, methods, and computer-readable media for radio resource management in a Citizens Broadband Radio Service (CBRS) network include one or more CBRS devices (CBSDs) which can obtain a group type associated with the CBSDs and their associated Radio Environment Map (REM) reports of one or more frequency channels of the CBRS network. The group type and the REM reports may be provided to a Self-Organizing Network (SON) manager of the CBRS network, where the SON manager may determine and provide to the CBSDs, one or more of a channel utilization information, transmission power, or mobility load management information for the CBSD, based on the group type and the REM reports.

An RF device may include RF circuitry having a PIN diode configured to switch an RF signal, and a biasing circuit. The biasing circuit may include a controllable power supply having a control input and an current output coupled to the PIN diode to selectively bias the PIN diode into an ON state, and a feedback circuit coupled between the current output and the control input of the controllable power supply to set a current delivered to the PIN diode in the ON state.

A method includes determining one or more active slots and inactive slots in an ultra-wide band (UWB) ranging round. The method also includes determining multiple UWB silent periods in the ranging round based on an arrangement of the inactive slots. The method also includes determining a sleep-wake-up schedule that aligns with at least one selected silent period of the multiple UWB silent periods in the ranging round, the sleep-wake-up schedule to be used for Wi-Fi communication. The method also includes waking up a Wi-Fi station (STA) for the Wi-Fi communication during the at least one selected silent period, then going back to sleep according to the sleep-wake-up schedule.

Methods, systems, and devices for wireless communication are described. A station may be communicating with an access point during a first active communication period. The communication may be performed in a first power mode. The station may switch to a second power mode to transition to a sleep period. The station may determine, based on traffic indicator metric(s), whether to perform a speculative wakeup and switch to the first power mode at the end of the sleep period.

Embodiments of this application provide a method for configuring physical downlink control channel (PDCCH) detection and a terminal device. The method includes: receiving a first indication signal sent from a network side, and obtaining a parameter for PDCCH detection based on the first indication signal; and detecting a PDCCH based on the parameter for PDCCH detection.

A power consumption control method, a chip system, and a terminal device in the field of terminal technologies is provided. The method includes: detecting, by a terminal device, a screen state and data traffic of the terminal device; and switching the terminal device from a normal working mode to a low power mode when the screen state is a screen-off state and the data traffic is less than or equal to a preset traffic threshold. In the low power mode, the terminal device does not receive downlink data, and current in a radio frequency path of the terminal device drops to a preset current, where the preset current is less than a current value of the radio frequency path in the normal working mode.

Embodiments of this application provide a method for adjusting a quantity of data streams, a terminal, and a MIMO system. In this method, the terminal may actively negotiate the quantity of transport layers used in a downlink data transmission process with a network device based on an operation status of the terminal, so as to adaptively and dynamically adjust the quantity of data streams in the downlink data transmission process. This may reduce power consumption of the terminal and prolong a standby time of the terminal without affecting user experience while meeting requirements for a data transmission rate of the terminal.

Methods and apparatuses for facilitating notification of an impending TDLS transmission in a wireless local area network. The apparatuses include a non-access point (AP) multi-link device (MLD) comprising stations (STAs) and a processor. Each STA comprises a transceiver configured to transceive signals on multi-link operation (MLO) links with APs of an AP MLD and on tunneled direct link setup (TDLS) direct links between the STAs and peer STAs of a second non-AP MLD, and to transmit, to the AP MLD on one of the MLO links, a TDLS transmission notification message. The processor is configured to determine that a TDLS transmission is impending over one of the TDLS direct links from one of the STAs that forms a non-simultaneous transmit/receive (NSTR) link pair with another STA, and to generate the TDLS transmission notification message, which includes an indication that the TDLS transmission is impending.

Embodiments provide an information transmission method, a base station, user equipment, and a system, which relate to the field of information transmission. The method includes: determining, by a network device, according to a correspondence between a characteristic parameter and a resource configuration, a first resource configuration corresponding to a characteristic parameter of the user equipment, wherein the characteristic parameter of the user equipment comprises a reference signal received power range, and the first resource configuration comprises one or more types of the following sub-configurations: a random access preamble format configuration, and a narrowband resource configuration; and determining, by the network device, a resource according to the first resource configuration, and performing, information sending or receiving with the user equipment by using the resource.

Tracking devices can be associated with safe zones, smart zones, and high risk zones. Safe zones correspond to regions where a likelihood that a tracking device is lost within the safe zone is lower than outside the safe zone. High risk zones correspond to regions where a likelihood that a tracking device is lost within the high risk zone is higher than outside the high risk zone. Smart zones correspond to an expected tracking device, mobile device, or user behavior. Home areas are geographic regions in which a user resides, and travel areas are geographic regions in which a user does not reside. A tracking device can be configured to operate in a mode selected based on a presence of the tracking device within a safe zone, a smart zone, a high risk zone, a home area, or a travel area.
