Abstract: An uplink non-orthogonal multiple access for narrowband machine type communication used for the deployment of Internet of Things (IoT) interconnected devices where one or more user equipment are configured for uplink transmission with one or more uplink time-frequency regions for enhanced Machine Type Communication Non-Orthogonal Multiple Access. The configuring is based on defining and signaling one or more signal thresholds and one or more of a resource assignment, a starting subframe periodicity, a starting subframe offset, a time duration in each period, a demodulation reference signal cyclic shift assignment, orthogonal cover code assignment, and interleaver assignment.

Abstract: Encoding System for Incremental Redundancy for Hybrid ARQ for Wireless Networks A technique is provided for encoding, by an outer encoder, a set of information bits; performing, by each polar sub-encoder of a set of polar sub-encoders, polar encoding of bits received from the outer encoder for a corresponding incremental redundancy (IR) hybrid ARQ (HARQ) transmission; and performing, by an inner encoder, for each bit input to the inner encoder from one of the polar sub-encoders for the HARQ transmission, an Exclusive Or (XOR) operation with another bit, to generate a set of code bits for an IR-HARQ transmission over a channel.

Abstract: The disclosure presents a method and system for enabling the monitoring of more than one propagation link (PL) between two transceivers, such as a fifth-generation (5G) broadband cellular base station (gNB) and user equipment (UE). The PL can represent a radiation pattern emitted by a MIMO antenna port. The monitoring can capture and record PL quality parameters and associate them to a PL index (PLI). The process can periodically cycle through the set of available PLs and select a best fit PLI configuration. The best fit PLI can be one that satisfies a link quality threshold and PL efficiency thresholds. The selected PLI can be communicated to both transceivers using parameter containers added to conventional control signals. Data messages communicated between the transceivers can utilize the selected best fit PLI configuration.

Abstract: Various communication systems may benefit from improved sounding reference symbol sounding techniques. An apparatus may comprise at least one memory comprising computer program code and at least one processor. The at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus at least to precode at least one uplink sounding reference symbol based upon at least one initial rank indicator and at least one first vector/matrix received from a network entity. The apparatus further transforms the first vector/matrix and a second vector matrix received from the network entity into a third vector/matrix based upon a final rank indicator received from the network entity. The apparatus further transmits data based upon the third vector/matrix.
