Embodiment Construction

[0047] It is generally recommended that downlink control information messages (in particular downlink control information according to the 3GPP standard)

[0051] It is contemplated that a network node (eg, a serving node (eg, a wireless network (or radio access network) in a wireless network)

[0052] DCI contains data for a number of different reporting types (eg, a CSI reporting type or a more general measurement reporting type).

[0053] Different reporting types, or in particular CSI reporting types, may be associated with different data transmission schemes. optional

[0063] • Interference reporting.

[0070] · High spatial resolution reporting may be indicated with eg 32 ports (eg CSI-RS ports).

[0071] Typically, the downlink control information message (and / or measurement report type indication) may indicate the number of ports, which may

[0072] In another embodiment, it can be considered that the interpretation of DCI messages is semi-statically configured by higher ...

Abstract

The present disclosure relates to a terminal for a radio access network, the terminal being adapted to send measurement reports on received reference signaling. The measurement report is based on one report type in a set of possible report types, and the terminal determines the report type of the measurement report based on a measurement report type indication in a downlink control information message received by the terminal. Additional related methods and apparatus are also disclosed.

Description

Dynamic CSI report type technical field [0001] The present disclosure relates to wireless communication technologies, and in particular to reference signaling. Background technique [0002] In LTE (Long Term Evolution, 3GPP wireless communication standard), there are defined 10 Transmission Modes (TM). For example, TM1 means single-antenna port transmission, TM2 means transmit diversity, and TM3 means open-loop spatial complex With, TM4 represents closed-loop spatial multiplexing, etc. [0003] Each TM and the feedback party for the measurement report (CSI report, channel state information report) of the user equipment (UE) case related. For example, if TM1 is configured, the UE measures the channel using a single antenna port and calculates the CQI (Channel Quality Indicator, information about the transmission quality on / on the channel). For example, if TM4 is configured, the UE measures from multiple antenna ports quantify the channel and calculate the CQI, PMI ...
