摘要： Methods, systems and apparatus are provided for hybrid automatic repeat request (HARQ) processes for different transmission time interval (TTI) lengths. A wireless transmit/receive unit (WTRU) may link a first HARQ process and a second HARQ process. The WTRU may transmit a first transport block (TB) using the linked first HARQ process and a first HARQ buffer. The WTRU may receive a uplink (UL) grant and determine that the received UL grant is for a new transmission for the linked second HARQ process. The WTRU may release the first HARQ buffer based on a determination that the received UL grant is for the new transmission for the linked second HARQ process. Also, the WTRU may generate a second TB for the new transmission and store the new TB in the first HARQ buffer. The WTRU may transmit the second TB using the linked second HARQ process and the first HARQ buffer.

摘要： Systems, methods, and instrumentalities are disclosed for antenna virtualization, e.g., in at least a two-dimensional antenna array. N E physical antenna elements may be virtualized to Np logical antenna ports. A virtualization may be WTRU-specific, which may optimize MIMO performance. A simplified MIMO scheme may be used with reduction in feedback, reference signal, and/or control signaling overhead. Antenna virtualization schemes may utilize channel characteristics. Antenna virtualization may be defined, for example, based on antenna port to antenna element mapping, based on a measurement reference signal, based on a codebook or a codebook subset or based on an antenna virtualization matrix. One or more antenna virtualization schemes may be configured in a cell. Antenna virtualization schemes may be configured in a WTRU-specific manner, perhaps for example based on a WTRU channel characteristic(s). A WTRU may report one or more useful (e.g., optimized) antenna virtualization schemes, e.g., based on one or more measurements.

摘要： A WTRU may include a memory and a processor. The processor may be configured to receive beam grouping information from a gNB or transmission and reception point (TRP). The beam grouping information may indicate a group of beams that the WTRU may report using group-based reporting. The group-based reporting may be a reduced level of reporting compared to a beam-based reporting. The group-based report may include measurement information for a representative beam. The representative beam may be one of the beams in the group or represents an average of the beams in the group. Alternatively, the representative beam may be a beam that has a maximum measurement value compared to other beams in the group. The group-based report may include a reference signal received power (RSRP) for the representative beam and a differential RSRP for each additional beam in the beam group.

摘要： A wireless transmit/receive unit (WTRU) may receive a PDCCH transmission comprising a CCE that is mapped to one or more REGs based on a CCE-to-REG mapping. The WTRU may receive the CCE-to-REG mapping that indicates a REG bundle corresponding to the CCE and use the CCE-to-REG mapping to identify the REGs for the WTRU. Depending on whether the CCE-to-REG mapping is interleaving or non interleaving, the CCE-to-REG mapping may be based on different parameters. If the CCE-to-REG mapping is interleaving, the CCE-to-REG mapping may be based on an index associated with the CCE and a number of REGs in the REG bundle. If the CCE-to-REG mapping is noninterleaving, the CCE-to-REG mapping may be based on the index of the CCE.

摘要： Methods and systems for sending and receiving an enhanced downlink control channel are disclosed. The method may include receiving control channel information via an enhanced control channel. The method may also include using the control channel information to receive a shared channel. The method may include detecting the presence of the enhanced control channel in a given subframe. The enhanced control channel may be transmitted over multiple antenna ports. For example, code divisional multiplexing and de-multiplexing and the use of common and VE-specific reference signals may be utilized. New control channel elements may be defined, and enhanced control channel state information (CSI) feedback may be utilized. The presence or absence oflegacy control channels may affect the demodulation and or decoding methods. The method may be implemented at a WTRU.
