Abstract
An access node, AN, may be configured to communicate wirelessly with a wireless device (WD). The AN can transmit a first synchronization signal block having a first format. The AN can also transmit a second synchronization signal block of a second format, the first synchronization signal block including a first format different from the format of the second synchronization signal block. The first synchronization signal block can include an extended primary synchronization signal block that can be used to synchronize disadvantaged user equipment (e.g., user equipment experiencing low signal-to-noise ratio).
Claims29
A method performed at an access node, AN, the AN configured to communicate wirelessly with a wireless device (WD), the method comprising:
- transmitting from the AN a first synchronization signal block of a first format comprising an extended primary synchronization signal and an extended secondary synchronization signal for a first duration of time;
- and
- transmitting from the AN a second synchronization signal block of a second format comprising a primary synchronization signal and a secondary synchronization signal for a second duration of time, the first duration of time comprising a longer duration than the second duration,
- wherein the AN is identified using an AN-ID that is one of a plurality of unique AN-IDs, the plurality of unique AN-IDs being divided into a plurality of groups, each group comprising a plurality of members, such that each of the plurality of unique AN-IDs corresponds to a specific group and a member of the specific group,
- wherein each of the extended secondary synchronization signal and the secondary synchronization signal indicates the same particular one of the groups, and
- wherein each of the extended primary synchronization signal and the primary synchronization signal indicates the same one of the members of the particular group indicated by the extended secondary synchronization signal and the secondary synchronization signal, thereby communicating to the wireless device, together with the particular group indicated by the extended secondary synchronization signal and the secondary synchronization signal, the AN-ID of the AN.
