Abstract

Generally, this disclosure provides apparatus and methods for improved User Equipment (UE) mobility in wireless heterogeneous networks. The UE device may include a location determination module configured to determine location information associated with the UE relative to one or more of a cells, wherein the of cells form part of a wireless heterogeneous network; a processing circuit configured to generate an assistance message, the assistance message including the location information associated with the UE; and a transmitter circuit configured to transmit a Radio Resource Control (RRC) message to an evolved Node B (eNB) associated with one of the cells, the RRC message including the assistance message.

First claim

What is claimed is:

1. User Equipment (UE) comprising:
a location determination module configured to determine location information associated with said UE relative to one or more of a plurality of cells, wherein said plurality of cells form part of a wireless heterogeneous network;
a processing circuit configured to generate an assistance message, said assistance message comprising said location information associated with said UE; and
a transmitter circuit configured to transmit a Radio Resource Control (RRC) message to an evolved Node B (eNB) associated with one of said plurality of cells, said RRC message comprising said assistance message.

2. The UE of claim 1 , wherein said location determination module is further configured to determine location of said UE based on a received signal selected from the group consisting of a GPS signal, a received Cell ID and a received WiFi SSID.

3. The UE of claim 1 , wherein said location information further comprises an indication of motion of said UE from a first cell of said plurality of cells towards a second cell of said plurality of cells.

4. The UE of claim 1 , wherein said assistance message further comprises a preferred cell carrier frequency.

5. The UE of claim 1 , wherein said assistance message further comprises a preferred Physical Cell Identity (PCI).

6. The UE of claim 1 , further comprising memory coupled to said processing circuit, an input/output (I/O) system coupled to said processing circuit, and a touchscreen display coupled to said I/O system.
