Abstract

A user equipment including a first radio sub-system configured to use a first radio access technology; a second radio sub-system configured to use a second radio access technology different to the first radio access technology; a data interface configured for transfer of parameters between the first radio sub-system and the second radio sub-system; wherein the a first radio sub-system is configured to send in-device co-existence relevant parameters to second radio sub-system, wherein the in-device co-existence parameter at least indicates a radio resource, in a frequency domain and/or a time domain.

First claim

We claim:

1. A user equipment comprising:
a first radio sub-system configured to use a first radio access technology;
a second radio sub-system configured to use a second radio access technology different to the first radio access technology;
a data interface configured for transfer of parameters between the first radio sub-system and the second radio sub-system;
wherein the first radio sub-system is configured to send at least a first in-device co-existence relevant parameter to the second radio sub-system, wherein the first in-device co-existence parameter at least indicates a radio resource in a frequency domain and/or a time domain,
wherein the second radio sub-system is configured to use the first in-device co-existence relevant parameter sent from the first radio sub-system to avoid or reduce interference between the first radio sub-system and the second radio sub-system,
wherein the second radio sub-system is configured to control its use of at least radio resources in a frequency domain and a time domain in dependence upon the first in-device co-existence parameter,
wherein the second radio sub-system is configured to use the first in-device co-existence relevant parameter sent from the first radio sub-system to control allocation of transmission and reception resources, in a frequency domain and a time domain, associated with the second radio sub-system,
wherein the second radio sub-system is configured to use the data interface to send at least a second in-device co-existence relevant parameter to the first radio sub-system, wherein the second in-device co-existence parameter at least indicates a radio resource in a frequency domain and a time domain,
wherein the first radio sub-system is configured to use the second in-device co-existence relevant parameter sent from the second radio sub-system to avoid or reduce interference between the first radio sub-system and the second radio sub-system,
wherein the first radio sub-system is configured to control at least its use of radio resources in a frequency domain and a time domain in dependence upon the second in-device co-existence parameter,
wherein the first radio sub-system is configured to use the second in-device co-existence relevant parameter transferred from the second radio sub-system to control allocation of transmission and reception resources, in a frequency domain and a time domain, associated with the first radio sub-system,
wherein the data interface is configured for transfer of solicited responses and unsolicited responses between the first radio sub-system and the second radio sub-system;
wherein the first radio sub-system is configured to send the first in-device co-existence relevant parameters using an unsolicited response,
wherein the data interface is configured for transfer of 3GPP AT messages between the first radio sub-system and the second radio sub-system and
wherein the first radio sub-system is configured to send the first in-device co-existence relevant parameters using a 3GPP AT message,
wherein the first radio sub-system is a cellular radio telecommunications sub-system and the second radio sub-system is a radio modem sub-system or wherein the second radio sub-system is a cellular radio telecommunications sub-system and the first radio sub-system is a radio modem sub-system,
wherein the data interface is a direct data interface without an intervening processor between the first radio sub-system and the second radio sub-system, and the direct data interface is a direct physical connection between the first radio sub-system and the second radio sub-system,
wherein the second radio sub-system is configured to use clear channel assessment (CCA) in dependence upon received co-existence relevant parameters indicating the discontinuous reception (DRX) and discontinuous transmission (DTX) patterns of the 3GPP system.
