Abstract
A wireless device establishes a first link for communications with a cellular base station, wherein the first link uses a first channel as a carrier. The wireless device receives information from the cellular base station for configuring a second link between the wireless device and another wireless device, wherein the second link uses a second channel as a carrier and wherein the second channel is different than the first channel. The wireless device communicates directly with the other wireless device using the second link, wherein the second link resources are assigned by the cellular base station using the first link. The wireless device can use one or more uplink and/or downlink grants from the cellular base station to communicate directly with the other wireless device.
Claims20
A first wireless user device configured to operate in a cellular network, comprising:
- a radio, comprising a plurality of antennas;
- a processing element operably coupled to the radio;
- wherein the radio and the processing element are configured to:
- establish a first link for cellular communications with a cellular base station, wherein the first link uses a first frequency as a carrier;
- establish a second link for peer-to-peer communications with a second wireless user device, wherein the second link uses the first frequency;
- and
- employ antenna-array processing in the first wireless user device to reduce interference in the second link that is received by the cellular base station;
- wherein the antenna array processing comprises measuring a channel hu between the first wireless user device and the cellular base station, and computing an antenna-array weight vector that is in a null space of hu*huT, where * denotes conjugate and T denotes transpose.
An apparatus, comprising:
- a processor;
- and
- a non-transitory computer-readable memory communicatively coupled to the processor, the memory including a set of instructions stored thereon and executable by the processor to:
- establish a first link for cellular communications between a first wireless user device and a cellular base station, wherein the first link uses a first frequency as a carrier;
- establish a second link for peer-to-peer communications with a second wireless user device, wherein the second link uses the first frequency;
- and
- employ antenna-array processing in the first wireless user device to reduce interference in the second link that is received by the cellular base station;
- wherein the antenna array processing comprises measuring a channel hu between the first wireless user device and the cellular base station, and computing an antenna-array weight vector that is in a null space of hu*huT, where * denotes conjugate and T denotes transpose.
A computer program product, comprising a computer readable hardware storage device having computer readable program code stored therein, said program code containing instructions executable by one or more processors of a computer system to:
- establish a first link for cellular communications between a first wireless user device and a cellular base station, wherein the first link uses a first frequency as a carrier;
- establish a second link for peer-to-peer communications with a second wireless user device, wherein the second link uses the first frequency;
- and
- employ antenna-array processing in the first wireless user device to reduce interference in the second link that is received by the cellular base station;
- wherein the antenna array processing comprises measuring a channel hu between the first wireless user device and the cellular base station, and computing an antenna-array weight vector that is in a null space of hu*huT, where * denotes conjugate and T denotes transpose.
A method, comprising:
- establishing a first link for cellular communications between a first wireless user device and a cellular base station, wherein the first link uses a first frequency as a carrier;
- establish a second link for peer-to-peer communications with a second wireless user device, wherein the second link uses the first frequency;
- and
- employ antenna-array processing to reduce interference in the second link that is received by the cellular base station;
- wherein the antenna array processing comprises measuring a channel hu between the first wireless user device and the cellular base station, and computing an antenna-array weight vector that is in a null space of hu*huT, where * denotes conjugate and T denotes transpose.
