A device may operate within a specified frequency band within a specified coverage area of a wireless cellular network served by a cell. The device may monitor, during a cell-specific paging window, paging messages transmitted by the cell within the cell-specific paging window to devices operating within the specified coverage area and targeted to receive paging messages. The device may enter an idle state if the monitoring indicates that the paging messages do not include a respective paging message intended for the device. If the monitoring indicates that the paging messages include a paging message intended for the device, the device may process the paging message. Furthermore, the device may indicate to the cell, when attaching to the cell, whether the device has a capability to support standalone operation within the specified frequency band. If the indication is that the device does not support such standalone operation, the cell may not issue paging messages to the device.

Systems and methods for low-power auto-correlation antenna selection for multi-antenna systems are disclosed. In particular, a computing device, such as an Internet of Things (IoT) computing device, may include a transceiver operating with multiple antennas. For example, the computing device may operate under a low-power wireless standard such as Long Range BLUETOOTH LOW ENERGY (LR BLE). In an exemplary aspect, an antenna from amongst the multiple antennas may be selected based on which antenna is receiving a best copy of a periodic signal. The periodic signal is likely indicative of a preamble pattern and, as such, may be used to activate a cross-correlation circuit for signal detection confirmation. Power consumption is reduced by delaying activation of the cross-correlation circuit until a likely signal is detected by detection of the periodic signal.

Methods for performing power management of a multi-interface transponder (MIT) device, e.g., such as positional tag device. The MIT device may transition between various power states, e.g., based on detected events, such as detecting movement of the MIT device, receiving a wakeup signal, receiving an indication of a transition in transportation mode, and/or detecting that the MIT device may be lost, such as based on a lack of contact with another device for more than a threshold period of time.

According to an embodiment of the present disclosure, a method for transmitting, by a user equipment (UE), uplink data in a wireless communication system supporting a narrowband Internet of things (NB-IoT) system includes: receiving information related to a preconfigured uplink (UL) resource (PUR) for transmitting the uplink data in an RRC connected state; and transmitting the uplink data by using the preconfigured uplink resource (PUR) in an RRC idle state. In the transmitting of the uplink data, when the preconfigured UL resource (PUR) is a dedicated resource and there is no data to be transmitted in the preconfigured UL resource (PUR), transmission of the uplink data is skipped.

Certain aspects of the present disclosure provide techniques for downlink control information (DCI) format for power efficiency. A method that may be performed by a user equipment (UE) includes receiving, from a base station (BS), a first DCI message in a first symbol of a downlink control channel, the first DCI message comprising a portion of an identifier that consists of less than all parts of the identifier, the first symbol being one of a plurality of symbols in a time period. The method may also include, when the portion of the identifier corresponds to the UE, receiving downlink data via resources indicated by a second DCI message, the second DCI message received in a second symbol of the downlink control channel, the second DCI message indicating the resources for receiving downlink data, the second symbol being another one of the plurality of symbols in the time period.

Methods, systems, and devices for wireless communications are described. In one example, a first user equipment (UE) identifies a trigger condition associated with a first communication link with a base station and establishes a second communication link with a second UE. The UE may transmit a relay request to the second UE based on the trigger condition, wherein the relay request instructs the second UE to relay communications for the first UE. The first UE communicates with the base station via the second communication link. In another example, a base station establishes communication links with a first and second UE. The base station receives a data forwarding request that instructs the base station to use the second UE to relay communications between it and the first UE. The base station communicates with the first UE via the second communication link based at least in part on the relay request.

In a communication method, a first access point (AP) in a first AP multi-link device generates a management frame that includes a capability information field. The capability information field includes first indication information indicating whether a second AP, which is also in the first AP multi-link device, has performed a channel switch. The first AP then sends the management frame to a first station (STA).

A method of wireless communications by a sidelink UE (user equipment) includes receiving a first signal as part of a discontinuous reception (DRX) wake-up procedure at the beginning of a sidelink discontinuous reception (DRX) ON duration. The method also includes transmitting a response to the first signal as part of a DRX wake-up procedure. The method further includes starting a timer after sending the response. The method still further includes entering a sleep state upon not receiving a physical sidelink control channel (PSCCH) or physical sidelink shared channel (PSSCH) before the timer expires.

Various wireless communication methods are provided for controlling two or more wireless devices. In one embodiment, various processes optimize the wireless communication, especially when multiple devices are present in a system or a network. In another embodiment, various controlling devices are accommodated in a network of devices at different points in time. The speed at which the new controlling device comes into a range of the networked devices is improved with existing signatures of different wireless protocols or devices present in the network. In another embodiment, a change in the signal strength of a wireless device can be used to detect an object or person, such as an intruder.

This disclosure relates to a communication method and a device. When a terminal device determines not to monitor DCP on a first DCP monitoring occasion, the terminal device wakes up on a first group of carriers within first DRX on duration associated with the first DCP monitoring occasion, and wakes up or sleeps on a second group of carriers within second DRX on duration associated with the first DCP monitoring occasion. The first group of carriers includes one or more carriers configured for the terminal device, a first DRX configuration is applied to the first group of carriers, the first DRX on duration corresponds to the first DRX configuration, the second group of carriers includes one or more carriers configured for the terminal device, a second DRX configuration is applied to the second group of carriers, and the second DRX on duration corresponds to the second DRX configuration.
