  • Patent number: 11018794
    Abstract: A method and apparatus for transmitting or detecting primary synchronization signal. The receiver receives primary synchronization signal from a transmitter, and detects the sequence used in the received primary synchronization signal by using three root indexes. Here, the primary synchronization signal is generated by using a Zadoff-Chu sequence having one of the three root indexes. The three root indexes comprise a first index and a second index, and a sum of the first index and the second index corresponds to the length of the Zadoff-Chu sequence.

  • Patent number: 11012966
    Abstract: Techniques described herein allow for mobile positioning (i.e., the determination of the position of the UE) to be performed when the UE is in Idle mode. In some implementations, assistance data, that is used by the UE as part of the mobile positioning procedure, may be broadcast to the UE or transmitted to the UE within paging messages. The assistance data can potentially be sent to the UE in a number of time slots. In some implementations, the UE may perform measurements needed for mobile positioning only within discontinuous reception (DRX) occasions. Alternatively, in some implementations, the UE may perform measurements needed for mobile positioning outside of DRX occasions.
