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.

A first device of the wireless system receives a first set of sensing reference signals (RSs) over beams from a second device, performs first beam measurements based on the first set of sensing RSs, and transmits, to the second device, a first information report based on the beam measurements. The first information report includes a first type of sensing information. The first device also receives, from the second device, a second set of sensing RSs, performs second beam measurements based on the second set of sensing RSs, and transmits, to the second device, a second information report based on the second beam measurements. The second information report includes a second type of sensing information that is different from the first type of sensing information.

Abstract: A method and user equipment are provided. The method includes receiving a scheduling of a transmission on a target cell that collides with a scheduled transmission on a source cell; determining a time duration from an ending symbol of a physical downlink control channel (PDCCH) scheduling the transmission on the target cell to a first symbol of the transmission on the source cell; determining a time value based on a physical uplink shared channel (PUSCH) preparation time and a subcarrier spacing (SCS) configuration; and determining that the time duration is greater than the time value and, in response, performing the transmission on the target cell and cancelling the transmission on the source cell.
