Abstract

A wireless terminal of a cellular telecommunication system communicates with an access node via a cell and comprises receiver circuitry and processor circuitry. The receiver circuitry is configured to receive, from the cell, serving cell mobility information. The processor circuitry configured to determine, based on the serving cell mobility information, mobility state of the cell.

Claims (21)

1 . A wireless terminal of a cellular telecommunication system, the wireless terminal communicating with an access node via a cell, the wireless terminal comprising:

receiver circuitry configured to receive, from the cell, serving cell mobility information, and;

processor circuitry configured to determine, based on the serving cell mobility information, a mobility state of the cell,

wherein the mobility state is determined based on whether or not a physical cell identity PCI) of the cell, decoded in a primary synchronization signal (PSS) and a secondary synchronization signal (SSS), is included in a set of reserved PCIs.

2 . The wireless terminal of claim 1 , wherein the mobility state indicates whether or not at least one transmission and reception point (TRP) serving the cell has geographically moved.

3 . The wireless terminal of claim 1 , wherein the serving cell mobility information is included in one or more broadcasted signals.

4 . The wireless terminal of claim 1 , wherein the serving cell mobility information is included in a signal dedicated to the wireless terminal.

5 . The wireless terminal of claim 1 , wherein the set of reserved PCIs is configured to the wireless terminal by the access node.

6 . A method for a wireless terminal of a cellular telecommunication system, the wireless terminal communicating with an access node via a cell, the method comprising:

receiving, from the cell, serving cell mobility information, and

determining, based on the serving cell mobility information, a mobility state of the cell,

wherein the mobility state is determined based on whether or not a physical cell identity PCI) of the cell, decoded in a primary synchronization signal (PSS) and a secondary synchronization signal (SSS), is included in a set of reserved PCIs.

7 . An access node of a cellular telecommunication system, the access node serving a wireless terminal via a cell, the access node comprising:

processor circuitry configured to generate serving cell mobility information;

transmitter circuitry configured to transmit, via the cell, the serving cell mobility information, wherein;

the serving cell mobility information is configured to the wireless terminal to determine a mobility state of the cell, and

the mobility state is determined based on whether or not a physical cell identity (PCI) of the cell, decoded in a primary synchronization signal (PSS) and a secondary synchronization signal (SSS), is included in a set of reserved PCIs.

8 . The access node of claim 7 , wherein the mobility state indicates whether or not at least one transmission and reception point (TRP) serving the cell has geographically moved.

9 . The access node of claim 7 , wherein the serving cell mobility information is included in a one or more broadcasted signals.

10 . The access node of claim 7 , wherein the serving cell mobility information is included in a signal dedicated to the wireless terminal.

11 . The access node of claim 7 , wherein the set of reserved PCIs is configured to the wireless terminal by the access node.
