## Abstract

A communication apparatus is disclosed, which comprises a base station module and an access point module for providing wireless connectivity to a communication network to at least one mobile communication device; an interface for coupling the base station module and the access point module for performing at least one of: a channel restriction operation; a power restriction operation; an intelligent uplink scheduling operation; a carrier frequency reselection operation; and a traffic steering operation; whereby alleviating an interference arising due to coexistence of the base station module and the access point module.

## Claims

### Claim 1

An eNB comprising:
a transceiver configured to communicate with a user equipment (UE) and configured to provide Long Term Evolution (LTE) connectivity for the UE, the UE configured to use radio resources of an LTE network and a wireless local area network (WLAN); and
a controller configured to:
request, over a dedicated interface, from a communication device for providing a connectivity between the UE and the WLAN, a load information of the WLAN;
receive, over the dedicated interface, the requested load information from the communication device; and
receive, from the communication device over the dedicated interface, WLAN information identifying at least one channel or frequency band of the WLAN.

### Claim 2 (depends on 1)

The eNB according to claim 1 wherein the load information comprises information identifying a number of UEs served by the communication device.

### Claim 3 (depends on 1)

The eNB according to claim 1 wherein the load information comprises information identifying an available capacity of the communication device.

### Claim 4

A communication apparatus comprising:
a transceiver configured to communicate with a user equipment (UE) and configured to provide a wireless local area network (WLAN) connectivity for the UE, the UE configured to use radio resources of a Long Term Evolution (LTE) network and the WLAN; and
a controller configured to:
receive, over a dedicated interface, from an eNB for providing a connectivity between the UE and the LTE network, a request for a load information of the WLAN;
send, over the dedicated interface, the load information to the eNB in accordance with the request; and
send, to the eNB over the dedicated interface, WLAN information identifying at least one channel or frequency band of the WLAN.

### Claim 5

A method performed by an eNB comprising a communication module configured to communicate with a user equipment (UE) and configured to provide Long Term Evolution (LTE) connectivity for the UE, the UE configured to use radio resources of an LTE network and a wireless local area network (WLAN), the method comprising:
requesting, over a dedicated interface, from a communication device for providing a connectivity between the UE and the WLAN, a load information of the WLAN;
receiving, over the dedicated interface, the requested load information from the communication device; and
receiving, from the communication device over the dedicated interface, WLAN information identifying at least one channel or frequency band of the WLAN.

### Claim 6

A method performed by a communication device configured to communicate with a user equipment (UE) and configured to provide a wireless local area network (WLAN) connectivity for the UE, the UE configured to use radio resources of a Long Term Evolution (LTE) network and the WLAN, the method comprising:
receiving, over a dedicated interface, from an eNB for providing a connectivity between the UE and the LTE network, a request for a load information of the WLAN;
sending, over the dedicated interface, the load information to the eNB in accordance with the request; and
sending, to the eNB over the dedicated interface, WLAN information identifying at least one channel or frequency band of the WLAN.
