Flexible early measurement reporting
Systems and methods are disclosed herein that provide reporting of early measurements in a cellular communications system. Embodiments of a method performed by a wireless device are disclosed. Early measurements are also referred to herein as dormant mode measurements. In some embodiments, a method performed by a wireless device includes performing one or more dormant mode measurements, where the one or more dormant mode measurements are one or more measurements performed by the wireless device while the wireless device is in a dormant mode. The method further includes storing the one or more dormant mode measurements, identifying a reporting scheme to be used by the wireless device to report dormant mode measurements, and reporting at least one of the stored dormant mode measurements in accordance with the identified reporting scheme. Corresponding embodiments of a wireless device are also disclosed.
1. A method performed by a wireless device, the method comprising:
performing one or more dormant mode measurements, the one or more dormant mode measurements being one or more measurements performed by the wireless device while the wireless device is in a dormant mode;
storing the one or more dormant mode measurements;
receiving an implicit indication, from a network node, identifying a reporting scheme from among a defined set of two or more reporting schemes for dormant mode measurements to be used by the wireless device to report dormant mode measurements, the implicit indication being:
information that indicates whether short Inactive Radio Network Temporary Identifier, I-RNTI, or full I-RNTI is to be used at connection resume; or
a size of uplink grant(s) for msg3 or msg5, and
the implicit indication identifying one of:
a reporting scheme in which dormant mode measurements are reported with msg3 during a Radio Resource Control, RRC, resume procedure;
a reporting scheme in which dormant mode measurements are reported with msg5 during the RRC resume procedure; and
a reporting scheme in which dormant mode measurements are reported using UElnformationRequest/Response; and
reporting at least one of the stored one or more dormant mode measurements in accordance with the identified reporting scheme based on the implicit indication received from the network node.
2. A wireless device, comprising:
one or more transmitters;
one or more receivers; and
processing circuitry associated with the one or more transmitters and the one or more receivers, the processing circuitry configured to:
perform one or more dormant mode measurements, the one or more dormant mode measurements being one or more measurements performed by the wireless device while the wireless device is in a dormant mode;
store the one or more dormant mode measurements;
receive an implicit indication identifying a reporting scheme from among a defined set of two or more reporting schemes for dormant mode measurements to be used by the wireless device to report dormant mode measurements, the implicit indication being:
information that indicates whether short Inactive Radio Network Temporary Identifier, I-RNTI, or full I-RNTI is to be used at connection resume; or
a size of uplink grant(s) for msg3 or msg5, and
the implicit indication identifying one of:
a reporting scheme in which dormant mode measurements are reported with msg3 during a Radio Resource Control, RRC, resume procedure;
a reporting scheme in which dormant mode measurements are reported with msg5 during the RRC resume procedure; and
a reporting scheme in which dormant mode measurements are reported using UElnformationRequest/Response; and
report at least one of the stored one or more dormant mode measurements in accordance with the identified reporting scheme based on the implicit indication received from the network node.
3. A method performed by a base station, the method comprising:
providing, to a wireless device, an implicit indication identifying a reporting scheme from among a defined set of two or more reporting schemes for dormant mode measurements to be used by the wireless device to report dormant mode measurements, the dormant mode measurements being one or more measurements performed by the wireless device while the wireless device is in a dormant mode, the implicit indication being:
information that indicates whether short Inactive Radio Network Temporary Identifier, I-RNTI, or full I-RNTI is to be used at connection resume; or
a size of uplink grant(s) for msg3 or msg5, and
the implicit indication identifying one of:
a reporting scheme in which dormant mode measurements are reported with msg3 during a Radio Resource Control, RRC, resume procedure;
a reporting scheme in which dormant mode measurements are reported with msg5 during the RRC resume procedure; and
a reporting scheme in which dormant mode measurements are reported using UEInformation Request/Response.
4. A base station, comprising:
processing circuitry configured to cause the base station to:
provide, to a wireless device, an implicit indication identifying a reporting scheme from among a defined set of two or more reporting schemes for dormant mode measurements to be used by the wireless device to report dormant mode measurements, the dormant mode measurements being one or more measurements performed by the wireless device while the wireless device is in a dormant mode, the implicit indication being:
information that indicates whether short Inactive Radio Network Temporary Identifier, I-RNTI, or full I-RNTI is to be used at connection resume; or
a size of uplink grant(s) for msg3 or msg5, and
the implicit indication identifying one of:
a reporting scheme in which dormant mode measurements are reported with msg3 during a Radio Resource Control, RRC, resume procedure;
a reporting scheme in which dormant mode measurements are reported with msg5 during the RRC resume procedure; and
a reporting scheme in which dormant mode measurements are reported using UElnformationRequest/Response.
