The UE may process non-access stratum (NAS) messages, for both mobile originated (MO) data transfer and mobile terminated (MT) data transfer, using the reliable data service protocol to determine whether protocol data units (PDUs) of the NAS messages require no acknowledgement, require acknowledgment, or include an acknowledgement, and to detect and eliminate duplicate PDUs received at the UE in the NAS messages.

Abstract: Systems and methods for Channel State Information (CSI) feedback on small control channels are provided. In some embodiments, a method of operation of a second node connected to a first node in a wireless communication network includes reporting CSI feedback to the first node on a physical channel. In some embodiments, this is accomplished by identifying a subset of codebook entries from an advanced CSI codebook of coefficients; selecting a codebook entry from the subset of codebook entries; and reporting an index of the selected codebook entry from the subset of codebook entries. This may allow robust feedback and allow variably sized cophasing and beam index indicators to be carried on the channel. Also, this may allow periodic feedback of advanced CSI on existing Physical Uplink Control Channel (PUCCH) Format 2.

Abstract: A signal transmission method is provided. The method includes: determining a target device, and transmitting a 5G signal to the target device, where the 5G signal includes a synchronization block, and the synchronization block is used to carry a PBCH, a PSS, an SSS and a DMRS, and the DMRS and the SSS are used as references for a demodulation result of the PBCH. By further setting the DMRS in the synchronization block, both the SSS and the DMRS are used as the references for the demodulation result of the PBCH, thereby ensuring that an adjusted phase of the demodulation result is as same as possible to a phase of the synchronization block before modulation of a transmission device, which greatly eliminates influence of factors such as the Doppler effect on the phase of the synchronization block during a signal transmission process.
