Abstract: A system and a method are disclosed for PRACH for coverage enhancements. In some embodiments, the method includes: transmitting, by a User Equipment (UE), a first Physical Random Access Channel (PRACH) transmission in a first Random Access Channel Occasion (RO); and transmitting, by the UE, a second PRACH transmission in a second RO, the second PRACH transmission being a repetition of the first PRACH transmission, the second RO having an index differing from an index of the first RO by a set integer.

Abstract: A system and a method are disclosed for dynamic spectrum sharing. In some embodiments, the method includes: processing, by a User Equipment (UE), a first transmission overlapping, in an orthogonal frequency division multiplexing (OFDM) symbol and in a Resource Block (RB), a Long Term Evolution Cell Specific Reference Signal (LTE CRS) transmission, the first transmission including: a Physical Downlink Control Channel (PDCCH) Demodulation Reference Symbol (DMRS) transmission, or a Physical Downlink Shared Channel (PDSCH) DMRS transmission, or a PDCCH data transmission.

Abstract: A system and a method are disclosed for sending enhanced feedback through PSFCH resources. In an embodiment, a receiving user equipment (Rx UE) determines that enhanced feedback is to be sent to a transmitting user equipment (Tx UE), such as based on resource pool configuration, a request from the Tx UE for enhanced feedback, or detection of a triggering event. The Rx UE encodes the enhanced feedback into a combination of a plurality of PSFCH resources based on an encoding scheme. The Rx UE then transmits the encoded feedback information in the plurality of PSFCH resources.

Abstract: A method for random access in a communication network may include detecting a first candidate beam at a UE, detecting a second candidate beam at the UE, transmitting, from the UE, one or more first messages of a random access procedure, and indicating, by the one or more first messages, the first candidate beam and the second candidate beam. Another method for random access in a communication network may include detecting a first candidate beam at a UE, detecting a second candidate beam at the UE, receiving, at the UE, traffic information for the first candidate beam and the second candidate beam, selecting the first candidate beam based on the traffic information, and transmitting, based on the selecting, a first message of a random access procedure using the first candidate beam. The traffic information comprises load information.

Abstract: A system and a method are disclosed for beam refinement to enable inactive mode transmission in frequency range 2 for 3GPP RedCap devices. A RedCap device receives system information in a SIB1 from a wireless network in which the SIB1 includes information relating to an indication of resources used to transmit a SIB-x. The device receives the SIB-x, which includes an indication of at least one resource, at least one configuration for a Downlink-Reference Signal (DL-RS) transmission, and information relating to a measurement report relating to the beam-refinement measurement that is to be performed by a device. The device receives the DL-RS transmission from the wireless communication network, performs the beam-refinement measurement, and sends a measurement report to the wireless network. Subsequent to sending the measurement report, the device sends an enhanced transmission to the wireless network based on the measurement report.
