Receiver and method for scanning and receiving wake-up signals with multiple configurations
First Claim
1. A method for receiving first signals and further signals using a receiver,the first and further signals differing in at least one of the transmission parameters:
- data rate, modulation type, wake-up criterion, synchronization and threshold, comprising the steps of;
a) in a first step in a quiescent mode of the receiver, performing receiving and searching for a first wake-up criterion intermittently using a first preset adjustable configuration of transmission parameters tuned for receiving the first wake-up criterion with a first data rate and/or a first modulation type and/or a first threshold; and
b) when the first wake-up criterion is not received or found in said quiescent mode, switching the receiver to at least one further configuration different from said first preset adjustable configuration and tuned for receiving a second wake-up criterion and searching for the second wake-up criterion, andc) if said first or second wake-up criterion has been received in step a) or b), switching the receiver into an active mode with a respectively selected configuration.

Abstract
A method for receiving first signals and further signals using a receiver, the first and further signals differing in at least one of the transmission parameters data rate, modulation type, wake-up criterion, synchronization and threshold value, comprises the steps of: in a first step, in a quiescent mode of the receiver, receiving and searching for a wake-up criterion (A) is performed intermittently using a first preset adjustable configuration of transmission parameters, and when no signal is received and no wake-up criterion (A) is found, the system switches to at least one further configuration and a search is made for a wake-up criterion (B).

6. A receiver for receiving first signals and further signals comprising a storage device for loading at least two different pre-definable receive configurations, wherein
the receiver has a quiescent mode in which it intermittently is turned on to receive and search for a first wake-up criterion using a first preset adjustable configuration of transmission parameters, and the receiver comprises a changeover switch in order to switch to at least one further second configuration different from said first configuration when the first wake-up criterion is not found, and to search for a second wake-up criterion, wherein the receiver is operable to switch into an active mode with said first or second configuration, respectively in case of a successful reception of said first or second wake-up criterion.

10. A motor vehicle comprising:
-
a receiver for receiving first signals and further signals comprising a storage device for loading at least two different pre-definable receive configurations, a first device coupled with said receiver; a second device coupled with said receiver; wherein the receiver is operable to operate in a quiescent mode in which it intermittently is turned on to receive and search for a first wake-up criterion using a first preset adjustable configuration of transmission parameters, and wherein the receiver comprises a changeover switch in order to switch to at least a second preset adjustable configuration different from said first preset adjustable configuration when no signal is received and the first wake-up criterion is not found using said first preset adjustable configuration, and to search for a second wake-up criterion, wherein the receiver is operable to switch into an active mode with said first or second preset adjustable configuration, respectively in case of a successful reception of said first or second wake-up criterion. - View Dependent Claims (11, 12, 13)
