Abstract

The disclosure of the present invention proposes a method for receiving signals. The method may be performed by a wireless device and comprise: receiving synchronization signals (SSs) from a serving cell and from a neighbor cell; and receiving radio resource management reference signals (RRM-RSs) from the serving cell and from the neighbor cell.

Claims

1. A method for receiving signals, the method performed by a wireless device and comprising:

receiving synchronization signals (SSs) from a serving cell and from a neighbor cell; and

receiving radio resource management reference signals (RRM-RSs) from the serving cell and from the neighbor cell, respectively.

2. The method of claim 1,

wherein the RRM-RSs includes a first RRM-RS and a second RRM-RS, wherein the first RRM-RS includes a secondary synchronization signal (SSS), and

wherein the second RRM-RS is used to select a best beam of the serving cell

3. The method of claim 1, wherein the RRM-RSs from the neighbor cell is aligned with the SS from the neighbor cell.

4. The method of claim 1,

wherein the SS is received in a synchronization signal (SS) block,

wherein the SS includes a primary synchronization signal (PSS) and a secondary synchronization signal (SSS),

wherein the SS block includes the PSS, SSS, the RRM-RS and a physical broadcast channel (PBCH).

5. The method of claim 4,
