Abstract

A method for communicating in a wireless communications system includes generating a channel state information (CSI) process information element (IE) including a CSI process identifier, a non-zero padded CSI-reference signal (CSI-RS) identifier, an interference measurement resource (IMR) identifier, and channel quality indicator (CQI) report configuration information. The method also includes transmitting the CSI process IE.

First claim

What is claimed is:

1. A method for communicating in a wireless communications system, the method comprising:
selecting, by a network node, a first channel quality indicator (CQI) report configuration from a plurality of CQI report configurations, each of the plurality of CQI report configurations comprising a set of parameters specifying a manner in which CQls are reported, and each of the plurality of CQI report configurations is associated with a CQI report configuration identifier uniquely identifying a respective CQI report configuration from the plurality of CQI report configurations; and
transmitting, by the network node, a message comprising a channel state information (CSI) process (CSI-process) information element (IE) to a user equipment (UE), the CSI-process IE specifying a CSI process configuration on a serving frequency,
wherein the CSI-process IE carries one or more CSI-process fields, the one or more CSI-process fields including a first CQI report configuration identifier (cqi-ReportConfig-Id) associated with the first CQI report configuration and uniquely identifying the first CQI report configuration from the plurality of CQI report configurations, the first CQI report configuration comprising a first set of parameters specifying a first manner according to which CQls are reported, and
wherein the CSI-process IE further comprises a periodic CQI report configuration identifier identifying a periodic CQI report configuration.

2. The method of claim 1 , wherein the message further comprises a CQI report configuration IE.

3. The method of claim 1 , wherein the CSI-process IE further comprises an aperiodic CQI report configuration identifier identifying an aperiodic CQI report configuration.

4. The method of claim 1 , wherein the CSI-process IE further comprises information about a single CSI process.

5. The method of claim 1 , wherein the CSI-process IE further comprises information about CSI processes associated with a single receiving device.

6. The method of claim 1 , wherein the CSI-process IE further comprises a power offset.

7. The method of claim 1 , further comprising receiving a CQI report in accordance with the first CQI report configuration.

8. The method of claim 1 , wherein the one or more CSI-process fields further comprise a csi-Process-ld, a csi-RS-Identity, or an imr-Id.

9. An apparatus, comprising:
a processor; and
a non-transitory computer readable storage medium storing programming for execution by the processor, the programming includes instructions to:
select a first channel quality indicator (CQI) report configuration from a plurality of CQI report configurations, each of the plurality of CQI report configurations comprising a set of parameters specifying a manner in which CQls are reported, and each of the plurality of CQI report configurations is associated with a CQI report configuration identifier uniquely identifying a respective CQI report configuration from the plurality of CQI report configurations; and
transmit a message comprising a channel state information (CSI) process (CSI-process) information element (IE) to a user equipment (UE), the CSI-process IE specifying a CSI process configuration on a serving frequency,
wherein the CSI-process IE carries one or more CSI-process fields, the one or more CSI-process fields including a first CQI report configuration identifier (cqi-ReportConfig-Id) associated with the first CQI report configuration and uniquely identifying the first CQI report configuration from the plurality of CQI report configurations, the first CQI report configuration comprising a first set of parameters specifying a first manner according to which CQls are reported,
wherein the CSI-process IE further comprises a periodic CQI report configuration identifier identifying a periodic CQI report configuration.

10. The apparatus of claim 9 , wherein the message further comprises a CQI report configuration IE.

11. The apparatus of claim 9 , wherein the CSI-process IE further comprises an aperiodic CQI report configuration identifier identifying an aperiodic CQI report configuration.

12. The apparatus of claim 9 , wherein the CSI-process IE further comprises information about a single CSI process.

13. The apparatus of claim 9 , wherein the CSI-process IE further comprises information about CSI processes associated with a single receiving device.

14. The apparatus of claim 9 , wherein the CSI-process IE further comprises a power offset.

15. The apparatus of claim 9 , wherein the programming comprises further instructions to receive a CQI report in accordance with the first CQI report configuration.

16. The apparatus of claim 9 , wherein the apparatus is one of an evolved NodeB and an entity tasked to configure CSI processes.

17. The apparatus of claim 9 , wherein the one or more CSI-process fields further comprise a csi-Process-ld, a csi-RS-Identity, or an imr-Id.

18. A method for communicating in a wireless communications system, the method comprising:
receiving, by a user equipment (UE) from a network node, a message comprising a channel state information (CSI) process (CSI-process) information element (IE), the CSI-process IE specifying a CSI process configuration on a serving frequency,
wherein the CSI-process IE carries one or more CSI-process fields, the one or more CSI-process fields including a first channel quality indicator (CQI) report configuration identifier (cqi-ReportConfig-Id) associated with an individual CQI report configuration of a plurality of CQI report configurations and uniquely identifying the individual CQI report configuration from the plurality of CQI report configurations, and each of the plurality of CQI report configurations comprising a set of parameters specifying a manner in which CQls are reported in a CSI process, and each of the plurality of CQI report configurations has an associated CQI report configuration identifier uniquely identifying a respective CQI report configuration from the plurality of CQI report configurations, wherein the individual CQI report configuration comprises a first set of parameters specifying a first manner according to which CQls are reported; and
selecting the individual CQI report configuration from the plurality of CQI report configurations in accordance with the first CQI report configuration identifier received; and
wherein the CSI-process IE further comprises a periodic CQI report configuration identifier identifying a periodic CQI report configuration.

19. The method of claim 18 , wherein the CSI-process IE further comprises an aperiodic CQI report configuration identifier identifying an aperiodic CQI report configuration.

20. The method of claim 18 , further comprising:
transmitting, by the UE, a CQI report in accordance with the individual CQI report configuration.

21. The method of claim 18 , wherein the one or more CSI-process fields further comprise one of a csi-Process-ld, a csi-RS-Identity, and an imr-Id.
