The timing synchronization signal may be based at least in part on the timing reference signal. The one or more terminals may be further configured to select a timing synchronization signal transmission rate. The one or more terminals may be further configured to broadcast the timing synchronization signal at the timing offset and at the timing synchronization signal transmission rate.

  • Patent number: 10667119
    Abstract: The invention relates to an improved transmission protocol for uplink data packet transmission. A transmission counter of the transmission protocol counts the number of transmissions the user terminal has performed for a data packet. The user terminal participates in sidelink discovery operation with other user terminals based on sidelink discovery gaps. The user terminal cannot transmit and/or receive signals under control of the transmission protocol when participating in sidelink discovery operation during the sidelink discovery gaps. A processor of the user terminal determines whether a retransmission of a data packet, which is triggered by the transmission protocol, was not performed because the transmission protocol operation collided with one of the sidelink discovery gaps.

  • Patent number: 10667323
    Abstract: Methods and apparatuses for releasing preconfigured uplink resources configuration in a wireless communication system are disclosed herein. In one method, a User Equipment (UE) receives a configuration of a preconfigured uplink resource (PUR) when the UE is in a first RRC_CONNECTED state. The UE enters a first RRC_IDLE state from the first RRC_CONNECTED state. The UE performs a first transmission using the PUR when the UE is in the first RRC_IDLE state. The UE enters a second RRC_CONNECTED state from the first RRC_IDLE state. The UE suspends the configuration when the UE is in the second RRC_CONNECTED state. The UE resumes the configuration when the UE enters a second RRC_IDLE state from the second RRC_CONNECTED state. The UE performs a second transmission using the PUR when the UE is in the second RRC_IDLE state.

  • Patent number: 10560894
    Abstract: HVAC components having improved efficiency are described. In one embodiment, excessive sleep current draw in a battery-powered device having a microcontroller is detected by measuring a voltage drop across a MOSFET device coupled in a for ward-conducting orientation in series between the battery and the microcontroller, causing a transistor to conduct when the voltage drop exceeds a predetermined threshold to generate a first trigger signal, integrating the first trigger signal to generate a second trigger signal, and generating an interrupt to the microcontroller. In another embodiment, a battery-saving method of operating an HVAC component includes maintaining the HVAC device in the sleep mode, receiving a user input to wake the device, transmitting a data request and returning the HVAC component to the sleep mode, waking up the HVAC device to poll an adjacent network node storing a cached response, displaying the response, and returning the HVAC device to sleep.
