SYNCHRONIZATION SIGNAL BLOCK SIGNALING FOR WIRELESS COMMUNICATIONS IN SHARED SPECTRUM
First Claim
1. A method for wireless communications, comprising:
- performing, by a base station, an access procedure to obtain access to a shared radio frequency spectrum band during a measurement window;
generating a synchronization signal (SS) burst comprising a plurality of SS blocks; and
performing, by the base station, a beam sweeping first transmission of the SS burst over the shared radio frequency spectrum based at least in part on the access procedure, wherein each SS block of the SS burst is transmitted during the first transmission using a different transmission beam;
wherein one of the first transmission, a second transmission by the base station, or a combination thereof comprises;
a first indication of a time of access to the shared radio frequency spectrum band with respect to the measurement window, a second indication of a transmission beam associated with the SS block, and a third indication of a quantity of remaining SS blocks from the plurality of SS blocks to follow the SS block in the measurement window.

Abstract
Methods, systems, and devices for wireless communication are described. A base station may perform an access procedure to obtain access to a shared radio frequency spectrum band during a measurement window and generate a synchronization signal (SS) burst comprising a plurality of SS blocks. The base station may perform a beam sweeping first transmission of the SS burst over the shared radio frequency spectrum based at least in part on the access procedure. In the first transmission or a second transmission, the base station may transmit at least one of a first indication of a time of access to the shared radio frequency spectrum band with respect to the measurement window, a second indication of a transmission beam associated with the SS block, and a third indication of a quantity of remaining SS blocks from the plurality of SS blocks to follow the SS block in the measurement window.
