Abstract
Methods and systems for reporting Channel State Information (CSI), including ordering of CSI in Uplink Control Information (UCI), are provided herein. According to one embodiment, a method performed in a wireless device for reporting CSI comprises at least one of: receiving an indication of a resource allocation for an UL transmission; determining, from the indication, a maximum container size for a CSI report; mapping the one or more information bits of a CSI report to a bitstream, optionally such that a first CSI subset is mapped to more significant bits than a second CSI subset; and omitting the one or more least significant bits of the bitstream.
Claims21
A method performed in a wireless device for reporting channel state information (CSI), the method comprising at least one of:
- receiving an indication of a resource allocation for an UL transmission;
- determining, from the indication, a maximum container size for a CSI report;
- mapping the one or more information bits of a CSI report to a bitstream;
- and
- omitting the one or more least significant bits of the bitstream.
A method performed in a wireless device for reporting Channel State Information (CSI), the method comprising at least one of:
- receiving an indication of a resource allocation for an UL transmission;
- determining, from the indication, a maximum number of bits allocated for a CSI report comprising CSI bits;
- generating a CSI report by mapping CSI bits according to a predefined order such that a first subset of the CSI bits is mapped to more significant bits than a second subset of the CSI bits;
- determining that the number of bits of the generated CSI report is larger than the maximum number of bits allocated for the CSI report;
- and
- in response to determining that the number of bits of the generated CSI report is larger than the maximum number of bits allocated for the CSI report, omitting the least significant bits of the generated CSI report that that exceed the maximum number of bits allocated for the CSI report.
A method performed in a base station for receiving Channel State Information (CSI) from a UE, the method comprising:
- sending, to the UE an indication of a resource allocation for an UL transmission;
- and
- receiving, from the UE, a CSI report comprising CSI bits that have been mapped according to a predefined order such that a first subset of the CSI bits is mapped to more significant bits than a second subset of the CSI bits.
A wireless device for reporting Channel State Information (CSI), the wireless device comprising:
- processing circuitry configured to:
- receive an indication of a resource allocation for an UL transmission;
- determine, from the indication, a maximum container size for a CSI report;
- map the one or more information bits of a CSI report to a bitstream;
- and
- omit the one or more least significant bits of the bitstream;
- and
- power supply circuitry configured to supply power to the wireless device.
A user equipment (UE) for reporting Channel State Information (CSI), the UE comprising:
- an antenna configured to send and receive wireless signals;
- radio front-end circuitry connected to the antenna and to processing circuitry, and configured to condition signals communicated between the antenna and the processing circuitry;
- the processing circuitry being configured to:
- receive an indication of a resource allocation for an UL transmission;
- determine, from the indication, a maximum number of bits allocated for a CSI report comprising CSI bits;
- generate a CSI report by mapping CSI bits according to a predefined order such that a first subset of the CSI bits is mapped to more significant bits than a second subset of the CSI bits;
- determine that the number of bits of the generated CSI report is larger than the maximum number of bits allocated for the CSI report;
- and
- in response to determining that the number of bits of the generated CSI report is larger than the maximum number of bits allocated for the CSI report, omit the least significant bits of the generated CSI report that that exceed the maximum number of bits allocated for the CSI report;
- an input interface connected to the processing circuitry and configured to allow input of information into the UE to be processed by the processing circuitry;
- an output interface connected to the processing circuitry and configured to output information from the UE that has been processed by the processing circuitry;
- and
- a battery connected to the processing circuitry and configured to supply power to the UE.
A communication system including a host computer comprising:
- processing circuitry configured to provide user data;
- and
- a communication interface configured to forward the user data to a cellular network for transmission to a user equipment (UE),
- wherein the cellular network comprises a base station having a radio interface and processing circuitry, the base station's processing circuitry configured to:
- send, to the UE, an indication of a resource allocation for an UL transmission;
- and
- receive, from the UE, a CSI report comprising CSI bits that have been mapped according to a predefined order such that a first subset of the CSI bits is mapped to more significant bits than a second subset of the CSI bits.
