摘要： Methods, apparatuses, systems, and/or procedures for reference signal (RS) transmissions and receptions in wireless communications (e.g., 5G NR) are disclosed. For example, a method implemented by a wireless transmit/receive unit (WTRU) includes receiving configuration information indicating a set of RS resources, a set of candidate RS resources, and a threshold; receiving a first RS in an RS resource of the set of RS resources; selecting a candidate RS resource from the set of candidate RS resources, based on a determination that a measurement result of the received first RS is less than or equal to the threshold; and receiving a second RS in the selected candidate RS resource.

摘要： Systems, apparatus and methods are described for dynamic demodulation signal resource allocation. PDSCH/PUSCH DMRS enhancement is provided. A dynamic indication of reference signal functionality may be provided in a slot for an additional DM-RS. A configured CSI-RS/SRS may be dynamically indicated to use as an additional DM-RS in a slot. Frequency shift/hopping of DM-RS as a function of OFDM symbol and/or the order of OFDM symbol containing DM-RS may increase frequency density within a slot. DM-RS antenna port aggregation may increase DM-RS frequency density. One or more DM-RS antenna ports may be used to demodulate the same layer. PDCCH DMRS enhancement is provided. Frequency shift/hopping of PDCCH DMRS may be provided as a function of a REG index within an REG bundle, OFDM symbol index, etc. Use of multiple types of REG (e.g., low and high DM-RS) and REG type may be determined based on subcarrier spacing, operating frequency band, etc.

摘要： Procedures, methods, architectures, apparatuses, systems, devices, and computer program products are disclosed that may be implemented in wireless transmit/receive unit (WTRU). In one representative method, the WTRU may determine a processing time value and/or type from among a plurality of processing time values and/or types and the method may include sending, by the WTRU to a network entity, a first message indicating the determined processing time value and/or type and receiving a second message indicating a confirmation of the determined processing time value and/or type. The method further may include applying, after receiving the confirmation of the determined processing time value type, the determined processing time value and/or type to processing of a target associated with the determined processing time value and/or type.
