Problems solved by technology

However, while polar codes perform well at larger values ​​of N, they suffer from poor minimum distances for lower values ​​of N, leading to the development of techniques such as sequential elimination list (SCL) decoding, This utilizes a simple outer code (such as CRC or parity) on top of a polar inner code with an excellent minimum distance, resulting in a combined code with an excellent minimum distance

Embodiment Construction

[0029] Certain aspects of the present disclosure generally relate to techniques for combining multiple decision metrics for a scrambled payload in a 5G wireless communication system. For example, in some cases, combining decision metrics for scrambled payloads may generally involve: receiving at the receiver a first payload that is scrambled both before and after encoding; a second payload of the selectively set payload mask bits; and descrambling the first payload using the selectively set payload mask bits in the second payload.

[0030] NR can support various wireless communication services such as enhanced mobile broadband (eMBB) targeting wider bandwidths (e.g., over 80MHz), millimeter wave (mmW) targeting higher carrier frequencies (e.g., 60GHz), Massive MTC (mMTC) targeting non-backward compatible MTC technologies and / or mission-critical targeting ultra-reliable low-latency communications (URLLC). These services may include latency and reliability requirements. These ...

Abstract

Certain aspects of the present disclosure generally relate to techniques for combining a plurality of decision metrics of a scrambled payload in a 5G wireless communications system. For example, in some cases, combining decision metrics of a scrambled payload may generally involve receiving a first payload at a receiver that was scrambled both before and after encoding, generating a second payloadat the receiver with selectively set payload mask bits, and using the selectively-set payload mask bits in the second payload to descramble the first payload.

Description

[0001] Priority claim based on 35 U.S.C. §119 [0002] This application claims priority to U.S. Application Serial No. 16 / 268,186, filed February 5, 2019, which benefits from U.S. Provisional Patent Application Serial No. 62 / 630,679, filed February 14, 2018, which is incorporated by reference Both applications are incorporated herein in their entirety. technical field [0003] In general, certain aspects of the present disclosure relate to wireless communications, and in particular, to methods and apparatus for combining decision metrics for scrambled payloads. 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 a multiple access technique capable of supporting communication with multiple users by sharing available system resources (eg, bandwidth, transmit power). Examples of such multiple acc...
