Abstract

A wireless communication method is described for user equipment to receive a report configuration, measure one or more resources, and generate a report to be transmitted to a base station. The report may include one or more CSI values describing the signal-to-interference plus noise ratio (SINR) or reference signal reception quality (RSRQ), and the CSI values are determined based on measuring at least some of one or more resources. The report may also include one or more identifiers associated with at least some of one or more channel measurement resources (CMR) or at least some of interference measurement resources (IMR), or at least some of one or more CMR groups or at least some of one or more IMR groups.

Description

Interference-Aware Beam Reporting in Wireless Communications The present disclosure relates generally to wireless communication. Mobile electronic communication technologies are transforming the world into an increasingly connected and networked society. Compared to existing wireless networks, next-generation systems and wireless communication techniques will need to support a much wider range of use case characteristics and provide a more complex and sophisticated range of access requirements and flexibility. Long-Term Evolution (LTE) is a wireless communication standard for mobile devices and data terminals developed by the 3rd Generation Partnership Project (3GPP). LTE Advanced (LTE-A) is a wireless communication standard that enhances the LTE standard. The 5th generation wireless system, known as 5G, is dedicated to advancing LTE and LTE-A wireless standards and supporting higher data rates, a large number of connections, ultra-low latency, high reliability, and other new business requirements. Techniques for interference-aware beam reporting are disclosed. An exemplary embodiment discloses a wireless communication method that receives a reporting configuration by a communication node. The reporting configuration is associated with one or more groups of channel measurement resources (CMRs) or one or more groups of interference measurement resources (IMRs). The method measures one or more CMRs included in one or more groups of CMRs or measures one or more IMRs included in one or more groups of IMRs. The method generates a report by a communication node comprising one or more channel state information (CSI) values describing a signal-to-interference-plus-noise ratio (SINR) or a reference signal received quality (RSRQ)—the one or more CSI values are determined based on measuring at least some of one or more CMRs or at least some of one or more IMRs—or one or more identifiers associated with at least some of one or more CMRs, at least some of one or more IMRs, at least some of one or more CMR groups, or at least some of one or more IMR groups. The method transmits the report to a network node. In some embodiments, interference measurements for at least one CSI value are obtained based on at least one IMR. In some embodiments, at least one IMR included in the report is associated with a first channel having a low correlation or low interference level with another channel of at least one CMR, or at least one CMR included in the report is associated with a second channel having a low correlation or low interference level with another channel of at least one IMR. In some embodiments, at least one IMR or at least one CMR included in the report is associated with a rank indicator (RI), wherein one RI is included in the report or configured for the report. In some embodiments, one or more CSI values are additionally based on one or more channel property assumptions (CPAs), one or more antenna groups, or one or more beam groups. In some embodiments, one or more IMRs within one IMR group from one or more IMR groups are associated with the same CPA. In some other embodiments, none of the one or more IMRs within one IMR group from one or more IMR groups are associated with the CPA. In some embodiments, one or more IMRs include one or more reference signal resources for channel measurement or one or more resources for interference measurement. In some embodiments, one or more CMRs include one or more reference signal resources for channel measurement. In some embodiments, each IMR within one IMR group from one or more IMR groups is associated with different spatial domain filters. In some embodiments, at least one CSI is associated with one or more identifiers associated with at least some of one or more IMRs or at least some of one or more IMR groups. In some embodiments, one or more CSI values are determined based on a set of the following reporting options: namely, one or more CMRs and one or more antenna groups; one or more CMRs and one or more beam groups; one or more CMRs, one or more antenna groups, and one or more beam groups; one or more CMRs, one or more IMRs, and one or more antenna groups; one or more CMRs, one or more IMRs, and one or more beam groups; and any one option from one or more CMRs, one or more IMRs, one or more antenna groups, and one or more beam groups. In some embodiments, one option is identified based on a reporting configuration, a CSI resource setting transmitted by a network node, or a measurement setting transmitted by a network node. In some embodiments, at least one CMR and at least one IMR are associated with at least one CSI value. In some embodiments, at least one CMR and at least one IMR are measured using the same receiving beam, the same antenna group, or the same receiving beam group. In some embodiments, at least one CMR and at least one IMR are received simultaneously by a communication node. In some embodiments, at least one IMR in the report or at least one group of IMRs i
