Techniques for sparse code multiple access (SCMA) codebook design

Abstract

The present disclosure describes a method, an apparatus, and a computer readable medium for a multilayer transmission in a wireless network. For example, the method may include generating a group of binary data bits for resources of each layer of a plurality of layers, mapping the group of binary data bits of each layer of the plurality of layers to respective code words in a signal constellation,combining the code words, and transmitting the combined code word to receiver in the wireless network. As such, the multilayer transmission in a wireless network is achieved.

Description

[0001] priority claim [0002] This patent application claims U.S. Provisional Patent Application No. 62 / 320,298, filed April 8, 2016, entitled "Techniques for Sparse CodeMultiple Access (SCMA) Codebook Design," and filed September 15, 2016, Priority to U.S. Patent Application No. 15 / 266,484, entitled "Techniques for Sparse Code Multiple Access (SCMA) Codebook Design," both assigned to the assignee of the present application, the entire contents of which are expressly incorporated by reference incorporated into this article. Background technique [0003] The present disclosure relates generally to communication systems and, more particularly, to codebook design in sparse code multiple access (SCMA) networks. [0004] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging and broadcast. Typical wireless communication systems may employ multiple-access techniques capable of supporting communica...
