Abstract: Methods, apparatuses, and computer-readable storage media are provided. An example method includes determining R demodulation reference signal (DMRS) ports for a transmission. R is greater than or equal to 2. The method includes determining N sets of one or more time-frequency domain resources for the transmission. N is greater than or equal to 1. The method includes determining RxN resource units on the R DMRS ports and the N sets of one or more time-frequency domain resources. RxN is greater than or equal to 3. The method includes mapping S complex-valued modulation symbols to the RxN resource units. The mapping is based on certain properties. The method includes transmitting, to an apparatus, the S complex-valued modulation symbols over the RxN resource units on the N sets of time-frequency domain resources based on the mapping and using the R DMRS ports.

Abstract: According to various embodiments, a wireless communication device divides a plurality of transmission beams into one or more groups of transmission beams including at least a first group of transmission beams. The wireless communication device determines a first sensing beam requirement for the first group of transmission beams. The wireless communication device determines a first sensing beam and a first scale factor so that the first sensing beam satisfies the first sensing beam requirement scaled by the first scale factor. The first sensing beam is selected from a set of candidate sensing beams. The wireless communication device performs a first Clear Channel Assessment (CCA) using the first sensing beam and a first energy detection threshold (EDT), the first EDT determined in accordance with the first scale factor.

Abstract: Embodiments of the present disclosure provide methods and apparatuses in the field of beam management. Some embodiments receive a downlink control information (DCI), the DCI scheduling one or more data channel transmissions. Some embodiments determines, a receive beam based on a time duration for quasi co-location (QCL), a scheduling offset, and a minimum time offset. Some embodiments receive using the receive beam, data symbols from the one or more data channel transmissions scheduled by the DCI.
