Abstract

Disclosed are techniques for wireless communication that over come problems associated with conventional approaches including load balancing and handover efficiency issues. For example, in one aspect a wireless communication technique takes into account the load of a relay before a UE is switched from one relay to another. In another example, a wireless communication technique ensures that UEs are handed over to relays that will be able to serve the UE as the mobile relay continues to follow its expected path (such as streets or tracks), which may be known or determined.

Dependent claims

A method of wireless communication, the method comprising:

connecting a user equipment (UE) to a first relay, the first relay connected to a network node;
receiving relay information by the network node or the UE, the relay information comprising location information of the first relay, signal strength information of the first relay, load information of the first relay, signal strength information of a second relay, load information of the second relay, location information of the second relay, wherein the second relay is connected to the network node;
determining, by the network node, whether a handover decision is positive or negative, wherein the handover decision is determined to be positive when a combination of one or more of the following is true:
the signal strength information of the first relay is below a strength threshold, the load information of the first relay is above a load threshold, the signal strength information of the second relay is above the strength threshold, the load information of the second relay is below the load threshold, a UE location relative to path information of a first relay location and path information of a second relay location;
and
connecting the UE to the second relay when the handover decision is determined to be positive.
