Communication devices and methods for network signaling

1. An apparatus comprising:

a detector to detect whether a first user equipment (“UE”) is to operate as a relay UE based on at least one radio signal from the first UE and to detect a request associated with network connectivity through a base station based on at least one radio signal from a second UE; and

a signaling circuit, coupled with the detector, to signal to the second UE information to facilitate selection, by the second UE, of the first UE for the network connectivity of the second UE via the first UE through the base station, wherein the information is based on a location of the first UE.

2. The apparatus of claim 1 , further comprising:

a storage circuit adapted to store information associated with a plurality of UEs that are operating as relay UEs.

3. The apparatus of claim 1 ,

wherein the first UE and the second UE are to operate in an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access Network (“E-UTRAN”).

4. The apparatus of claim 3 ,

a list generation circuit configured to generate a list of other UEs operating as relay UEs in a radio cell, wherein the list generation circuit is configured to include the first UE in the list if it has been detected that the other UE is operating as a relay UE.

5. The apparatus of claim 3 ,

wherein the apparatus is included in an LTE network.

6. The apparatus of claim 3 , further comprising:

an update circuit configured to update the list in response to the detection that one of the other UEs of the list has quit operation as a relay UE.

7. The apparatus of claim 6 ,

wherein the update circuit is configured to update the list at predetermined points in time.

8. The apparatus of claim 1 ,

wherein the detection whether the first UE is operating as a relay UE based on at least one radio signal from the first UE comprises to determine whether the first UE has quit operation as relay UE or has started operation as a relay UE.

9. The apparatus of claim 1 ,

wherein the detection whether the first UE is operating as a relay UE based on at least one radio signal from the first UE comprises to determine whether an expected signal is received from the first UE and to decide that the first UE does not operate as relay UE if the expected signal is not received from the first UE.

10. The apparatus of claim 1 , further comprising:

a receiver configured to receive signals associated with a relay UE.

11. An apparatus to be included in a user equipment (“UE”), the apparatus comprising:

first circuitry to transmit, to a communication device, a request associated with network connectivity through a base station and to receive, from the communication device based on the request, information to facilitate selection of a relay UE for the network UE, wherein the information associated with the relay UE is based on a location of the relay UE; and

second circuitry to select the relay UE based on the received information and to connect with the relay UE for the network connectivity through the base station based on the selection.

12. The apparatus of claim 11 , wherein the first circuitry is to transmit the request according to a first radio access technology and the second circuitry is to connect with the relay UE according to a second radio access technology.

13. The apparatus of claim 11 , wherein the apparatus is to operate in an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access Network (“E-UTRAN”).

14. One or more non-transitory computer-readable media comprising computing device-executable instructions, wherein the instructions, in response to execution by a communication device, cause the communication device to:

detect whether a first user equipment (“UE”) is to operate as a relay UE based on at least one radio signal from the first UE;

detect a request associated with network connectivity through a base station based on at least one radio signal from a second UE; and

signal, to the second UE, information to facilitate selection of a relay UE for the network connectivity of the second UE via the first UE through the base station, wherein the information is based on a location of the first UE.

15. The one or more non-transitory computer-readable media of claim 14 , wherein the instructions further cause the communication device to:

store information associated with a plurality of UEs that are operating as relay UEs.

16. The one or more non-transitory computer-readable media of claim 14 , wherein the first UE and the second UE are to operate in an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access Network (“E-UTRAN”).
