Abstract
Apparatuses and methods related to digital mobile radio (DMR) with enhanced transceiver are disclosed herein. The transceiver detects waveforms of signals received by a digital mobile station radio (MS). By detecting whether the waveforms of the signals, the transceiver allows a digital baseband processor of the MS to remain in a sleep state while the signals are being detected by the DMR, thereby reducing an amount of power used while the signals are being detected.
Claims20
An apparatus to perform signal detection, the apparatus to be coupled to a baseband integrated circuit (BBIC) of a mobile station radio (MS), and comprising:
- a storage module to store data associated with a signal received by an antenna of the MS;
- and
- a communication detection module to:
- generate a received signal strength indicator (RSSI) for the signal while the BBIC is in a sleep mode;
- and
- provide the RSSI to a microcontroller unit (MCU) of the MS, wherein the storage module is to provide the data to the BBIC based on the RSSI indicating that a received signal strength of the signal exceeds a threshold value.
A mobile station radio (MS), comprising:
- an antenna;
- a baseband integrated circuit (BBIC) to be in a sleep mode in wake periods of an idle state of the MS;
- and
- a transceiver coupled to the antenna and the BBIC, the transceiver comprising:
- a communication processing module to:
- receive data associated with signals from the antenna, the signals being received by the antenna during the wake periods;
- and
- produce processed data from the received data;
- and
- a microcontroller unit (MCU) to identify a digital mobile radio (DMR) signal or a frequency modulation (FM) signal from the processed data, wherein the MCU is to trigger a wake-up procedure of the BBIC in response to identification of the DMR signal or the FM signal.
One or more non-transitory, computer-readable storage media having instructions stored thereon, wherein the instructions, when executed by a microcontroller unit (MCU) of a transceiver of a digital mobile radio (DMR) mobile station radio (MS), cause the MCU to:
- identify a DMR signal or a frequency modulation (FM) signal from processed data retrieved from a communication processing module of the MS, the processed data associated with a signal received by the MS during a wake period of an idle state of the MS;
- trigger a wake-up procedure of a baseband integrated circuit (BBIC) in response to identification of the DMR signal or the FM signal;
- and
- cause the communication processing module to provide the processed data to the BBIC.
