A user equipment (UE) may sense a first transmission by a first sidelink UE and a second transmission by a second sidelink UE and send a conflict indication to at least one of the first or second sidelink UEs in response to identifying a collision between the first and second transmissions, or identifying a prospective collision based on a prospective use of respective first and second resources identified in the respective first and second transmissions. A collision or prospective collision may be detected by detecting a complete or partial overlap of the first and second transmissions or of the prospective first and second resources identified in the transmissions, or by determining that any portions of the first resource and the second resource prospectively occupy a slot common to the first and second resources, and the first sidelink UE and the second sidelink UE prospectively operate in a half-duplex mode.

Systems and methods for splitting cells in a network of Internet of Things (IOT) may evaluate a network metric such as receives signal strength indicator (RSSI) for end devices to determine a general network activity level. When the network metric falls below a predetermined threshold, the cell splitting controller may cause the cell to split in such a manner as to offload some portion of the end devices on an adjacent gateway and/or change frequencies to reduce the likelihood of collision. By splitting cells in this fashion, the density of end devices served by a single gateway is reduced, fewer collisions occur statistically, and the user experience may be improved.

A method and a user equipment of performing resource switching in an unlicensed spectrum are provided. A current set of resources in the unlicensed spectrum is utilized by a UE for performing LBT attempts for transmission of an RACH message to a base station. One or more LBT attempts for transmissions from the UE to the base station are performed over the current set of resources during a current RACH procedure. The current set of resources is switched to a new set of resources in the unlicensed spectrum to be utilized by the UE in a new RACH procedure after a failure count reaches a pre-configured threshold during the current RACH procedure. The failure count is calculated at least based on a count of LBT failure over the current set of resources during the current RACH procedure.

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.

The present invention discloses a safety devices adapted to prevent workers from going into hazardous environment, such as underground using the faulty safety device. As a safety device, typically embodied as a cap lamp, must be charged prior to each use, the device is adapted to detect when the device is removed from the charger. The device starts to blink continuously when disconnected from the charger. An automated test procedure is completed on the device. The user may also complete a manual portion of the test procedure to make the device usable. When the test procedure is completed successfully, the lamp stops blinking. If the test procedure is not successful, the lamp continues blinking to effectively prevent user from using a faulty device.
