Abstract

The present disclosure describes methods and systems applicable to transport block communication as part of multiple access wireless communications. The methods and systems include a base station (120) that determines a first order for a first plurality of non- orthogonal multiple access (NOMA) layers (705). The base station (120) receives, from a user equipment (110), the first plurality of NOMAlayers that carry the transport block (710). The base station (120) combines the first plurality of NOMA layers following the determined first order (715) and determines that decoding the transport block from the first plurality of NOMA layers has failed (720). The base station (120) then determines a second order for a second plurality of NOMA layers (725) and receives, from the user equipment (110), the second plurality of NOMA layers that carry the transport block (730). The base station (120) then combines the second plurality of NOMA layers following the second order to decode the transport block from the second plurality of NOMA layers (735).

Description

Background technique [0001] Multiple Access (MA) wireless communication technology is an important aspect of wireless communication networks. In general, multiple access wireless communication techniques provide for two or more user equipment (UE) devices, such as smartphones, to share resources of a wireless communication network in an efficient and effective manner. Resources may include, for example, physical resource blocks spanning time, frequency, or code domains that UE devices share when communicating with a base station supporting a wireless communication network. [0002] Today, wireless network communication providers are implementing Orthogonal Multiple Access (OMA) and Non-Orthogonal Multiple Access (NOMA) technologies to support multiple access as part of fifth-generation new radio (5G NR) networks. incoming communication. Using these techniques, UE devices can transmit data streams to base stations sharing MA resources or OMA or NOMA resources of the air inter...
