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.

Claims

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.
