US 2020/0052822 A1 · TECHNIQUES OF CSI FEEDBACK WITH UNEQUAL ERROR PROTECTION MESSAGES

Abstract

In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE determines priority levels of a plurality of messages based on at least one predetermined rule. The plurality of messages contain channel state information to be reported to a base station. The at least one predetermined rule specifies that a message including an indicator indicating at least one of a beam selection at a particular dimension and an orthogonal beam group selection has a priority level higher than a priority level of a message including an indicator indicating at least one of a beam direction from a group of beam candidates or co-phasing between two sets of antennas for two polarizations. The UE sends, to the base station, one or more messages of the plurality of messages based on the priority levels of the plurality of messages.

Dependent claims

A method of wireless communication of a user equipment (UE), comprising:

determining priority levels of a plurality of messages based on at least one predetermined rule, wherein the plurality of messages contain channel state information to be reported to a base station, wherein the at least one predetermined rule specifies that a message including an indicator indicating at least one of a beam selection at a particular dimension and an orthogonal beam group selection has a priority level higher than a priority level of a message including an indicator indicating at least one of a beam direction from a group of beam candidates or co-phasing between two sets of antennas for two polarizations;
and
sending, to the base station, one or more messages of the plurality of messages based on the priority levels of the plurality of messages.

A method of wireless communication of a user equipment (UE), comprising:

determining that a priority level of a first message is higher than a priority level of a second message based on at least one predetermined rule, wherein the first message and the second message contain channel state information to be reported to a base station;
and
mapping information bits of the first message to a first plurality of input bits of an encoder and information bits of the second message to a second plurality of input bits of the encoder, wherein, when the encoder is a Polar-code encoder, a reliability of at least one input bit of the first plurality of input bits is higher than a reliability of at least one input bit of the second plurality of input bits, and the reliability of the at least one input bit of the first plurality of input bits and the reliability of the at least one input bit of the second plurality of input bits are each defined by a correct rate or a log likelihood ratio (LLR) of a respective input bit.
