Abstract
A method for transmitting a scheduling request includes receiving, at a relay UE and from a remote UE, a sidelink control information. The relay UE is within a coverage area of a base station. The remote UE is outside of the coverage area. The relay UE is configured to relay transmissions from the remote UE to the base station, and the sidelink control information indicates a future transmission of a data packet over a sidelink channel. A scheduling request is transmitted to a base station. A scheduling grant that indicates an uplink resource is received from the base station. A data packet over the sidelink channel is received from the remote UE.
Claims17
A method for coordinating selection of radio resources between UEs (user equipments) capable of direct communication, comprising:
- transmitting, by a first UE to a second UE, a request to receive information of a first radio resource, wherein the first radio resource is selected by the second UE, and the first radio resource is used by the second UE for a first direct communication;
- in response to transmitting the request, receiving, at the first UE and from the second UE, the information of the first radio resource that is used by the second UE for the first direct communication;
- and
- in response to receiving the information of the first radio resource, selecting, at the first UE, a second radio resource, wherein the second radio resource is different from the first radio resource, and the second radio resource is used by the first UE for a second direct communication, wherein the first direct communication and the second direct communication are UE-to-UE communication.
A tangible, non-transitory computer-readable medium containing instructions which, when executed, cause one or more computing devices to perform a method for coordinating selection of radio resources between UEs (user equipments) capable of direct communication, the method comprising:
- transmitting, by a first UE to a second UE, a request to receive information of a first radio resource, wherein the first radio resource is selected by the second UE, and the first radio resource is used by the second UE for a first direct communication between;
- in response to transmitting the request, receiving, at the first UE and from the second UE, the information of the first radio resource that is used by the second UE for the first direct communication;
- and
- in response to receiving the information of the first radio resource, selecting, at the first UE, a second radio resource, wherein the second radio resource is different from the first radio resource, and the second radio resource is used by the first UE for a second direct communication, wherein the first and the second direct communication are UE-to-UE communication.
A first user equipment (UE), comprising:
- a memory;
- and
- at least one hardware processor communicatively coupled with the memory and configured to perform a method for coordinating selection of radio resources between UEs capable of direct communication, the method comprising:
- transmitting, by the first UE to a second UE, a request to receive information of a first radio resource, wherein the first radio resource is selected by the second UE, and the first radio resource is used by the second UE for a first direct communication
- in response to transmitting the request, receiving, at the first UE and from the second UE, the information of the first radio resource that is used by the second UE for the first direct communication;
- and
- in response to receiving the information of the first radio resource, selecting, at the first UE, a second radio resource, wherein the second radio resource is different from the first radio resource, and the second radio resource is used by the first UE for a second direct communication, wherein the first and the second direct communication are UE-to-UE communication.
