Reporting of channel properties in heterogeneous networks

摘要

Rank indicator and channel quality indicator (CQI) estimation and reporting functionalities are discussed with regard to heterogeneous networks to reduce the number of inconsistent CQI estimates transmitted to an evolved node B (eNB), where the CQI is defined as inconsistent when the rank indicator, on which the CQI is conditioned, is from a different subframe type than the subframe on which the CQI is to be estimated.

1. A method for wireless communication, comprising:
receiving a plurality of parameter values at a user equipment (UE) for reporting a plurality of channel properties associated with a resource, wherein the plurality of parameter values includes a first set of parameter values that includes a first periodicity and a first offset, and a second set of parameter values that includes a second periodicity and a second offset; estimating a first set of channel properties of the plurality of channel properties related to a first channel property, the estimating the first set of channel properties using the first set of parameter values of the plurality of parameter values to estimate at least a first rank indicator according to the first periodicity, wherein the first set of parameter values configures the estimating of the first set of channel properties for clean interlaces; estimating a second set of channel properties of the plurality of channel properties related to a second channel property, the estimating the second set of channel properties using the second set of parameter values of the plurality of parameter values to estimate at least a second rank indicator according to the second periodicity, wherein the second set of parameter values configures the estimating of the second set of channel properties for unclean interlaces, and the estimating of the first set of channel properties of the plurality of channel properties and the estimating of the second set of channel properties of the plurality of channel properties are performed in parallel; and transmitting the plurality of channel properties to an associated evolved node B (eNB).
