Single packet encoded channel state information (CSI) design for new radio (NR) multiple input-multiple output (MIMO)

Abstract

Certain aspects of the present disclosure generally relate to methods and apparatus for generating and encoding bits of CSI report. In some cases, a UE may determine a payload size for channel state information (CSI) reporting based, at least in part, on a supported rank, calculate a packet length for the CSI reporting based on the determined payload size, and encode the CSI for a selected CSI resource index (CRI), based on the payload size and the calculated packet length, to generate a coded packet.

[0001] Cross-References & Claims to Priority to Related Applications [0002] This application claims the benefit and priority of International Patent Cooperation Treaty Application No. PCT / CN2017 / 105237 filed on October 2, 2017, which is assigned to the assignee of this application and is hereby incorporated by reference is expressly incorporated herein as if fully set forth below and for all applicable purposes. technical field [0003] In general terms, certain aspects of this disclosure relate to transmitting and encoding bits of channel state information (CSI). Background technique [0004] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcast. A typical wireless communication system may employ multiple access techniques capable of supporting communication with multiple users by sharing available system resources (eg, bandwidth, transmit power). Examples of such multipl...

Problems solved by technology

However, although polar codes perform well for large values ​​of N, for lower values ​​of N the minimum distance of polar codes is poor, which has led to the development of techniques such as successive elimination list (SCL) decoding, SCL Decoding utilizes simple outer codes with excellent minimum distances over polar inner codes (such as CRC or parity), resulting in combined codes with excellent minimum distances
