Abstract: Methods, systems, and devices related to applying a spreading code to reference signals are described. In one exemplary aspect, a method for wireless communication includes receiving a message indicating a set of control options available to the mobile device for data transmissions. The method includes selecting a spreading code sequence from a number of spreading code sequences, wherein the spreading code sequence corresponds to a control option in the set of control options, wherein the number of spreading code sequences is greater than a length of each of the spreading code sequence, and wherein the spreading code sequences are generated using a method when the length of each of the spreading code sequences is greater than or equal to a value. The method also includes generating a plurality of reference signal symbols using the spreading code sequence, and transmitting the plurality of reference signal symbols.

Abstract: Reducing control signaling is an effective technique for increasing resource efficiency when supporting a massive number of connections in an Internet of Things framework. In the presence of sporadic and small data packets, the use of control signaling must be optimized to not overwhelm network resources. In some embodiments, a bit map in a control signaling packet may indicate if certain information elements that correspond to configuration parameters are present or absent. When they are absent, predetermined values for the corresponding configuration parameters may be used, whereas when they are present, predefined values from a set of predefined values may be used. In other embodiments, the predetermined values may be periodically updated.

Abstract: Optimizing the resource configuration or selection for grant-free contention-based non-orthogonal multiple access (NOMA) transmissions is an effective way to increase network capacity and reduce multi-user interference at the user equipment (UE). In some embodiments, a network node may determine the current traffic load, select multiple access (MA) sequences for the UE based on the determination, and transmit this selection to the UE for subsequent transmissions. In other embodiments, the UE may receive a message with an indication of the traffic load being experienced by the base station that the UE is attempting to connect to, and then may randomly select an MA sequence for subsequent transmissions.
