Method and apparatus for performing dynamic link selection
First Claim
1. In a communication system including a first transmit/receive unit (TRU) and a second TRU, a method of selecting a link used to establish communications between the first TRU and the second TRU, the method comprising:
- the first TRU determining whether the second TRU has multiple interfaces with a dynamic link selection (DLS) capability;
if the second TRU has multiple interfaces with the DLS capability, the first TRU sending a packet to the second TRU through a selected link over which the first TRU and the second TRU can communicate with each other and receiving a report from the second TRU; and
the first TRU selecting a link based on the report.

Abstract
A method and system for performing dynamic link selection (DLS) between transmit/receive units (TRUs). A first TRU determines whether a second TRU has multiple interfaces with a DLS capability. If the second TRU has multiple interfaces with the DLS capability, the first TRU sends a packet to the second TRU through a selected link. The first TRU then receives a report from the second TRU and evaluates quality of the link based on the report. The first TRU selects a link for a new packet in accordance with a predetermined criteria and the quality of the link. If the second TRU does not have multiple interfaces with the DLS capability, the first TRU periodically sends probe packets to the second TRU via all available links. The second TRU sends response packets and the first TRU evaluates the quality of link based on statistics of the response packets.

10. A transmit/receive unit (TRU) for dynamically selecting a link, the TRU comprising:
-
multiple sets of physical layers and medium access control (MAC) layers, each set of physical layer and MAC layer supporting an interface under a different communication protocol; and
a dynamic link selection (DLS) layer configured to determine whether another TRU has multiple interfaces with a DLS capability, whereby if another TRU has multiple interfaces with the DLS capability, the DLS layer sends a packet to another TRU through a selected link and selects a link for a new packet based on a report which is sent by another TRU and a predetermined criteria. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A communication system supporting dynamic link selection, the system comprising:
a plurality of transmit/receive units (TRUs), at least one TRU comprising;
multiple sets of physical layers and medium access control (MAC) layers, each set of physical layer and MAC layer supporting an interface under a different communication protocol; and
a dynamic link selection (DLS) layer configured to determine whether another TRU has multiple interfaces with a DLS capability, whereby if another TRU has multiple interfaces with the DLS capability, the DLS layer sends a packet to another TRU through a selected link and selects a link for a new packet based on a report which is sent by another TRU and a predetermined criteria. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)

28. An integrated circuit (IC) for selecting a link between transmit/receive units (TRUs) in communication, at least one link being established between the TRUs, the IC comprising:
-
multiple sets of physical layers and medium access control (MAC) layers, each set of physical layer and MAC layer supporting an interface under a different communication protocol;
a dynamic link selection (DLS) layer configured to determine whether another TRU has multiple interfaces with a DLS capability, whereby if another TRU has a DLS capability, the DLS layer sends a packet to another TRU through a selected link and selects a link for a new packet based a report from another TRU and a predetermined criteria. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36)
