摘要： Methods and apparatuses are described herein for providing a single-bit hybrid automatic repeat request (HARQ) feedback and a multi-bit HARQ feedback in a wireless transmit/receive unit (WTRU). For example, a WTRU may receive, via a physical downlink control channel (PDCCH), downlink control information (DCI). The DCI may include a field that indicates a code block group (CBG) based retransmission for at least one transport block (TB). On a condition that the DCI does not include the field, the WTRU may transmit, via a physical uplink control channel (PUCCH), a single-bit HARQ feedback for a TB-based retransmission. On a condition that the DCI includes the field, the WTRU may transmit, via the PUCCH, the multi-bit HARQ feedback for the CBG-based retransmission. The WTRU may be configured to provide the single-bit HARQ feedback for the TB-based retransmission and a multi-bit HARQ feedback for the CBG-based retransmission.

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 beamin the beam group.

摘要： A system, method, and device for ensuring a number of Phase Tracking Reference Signal(s) (PT-RSs) are the same for multiple slots. A wireless transmit/receive unit (WTRU) may receive control information including a number of scheduled resource blocks (RBs) then determine a PT-RS density based on the number of scheduled RBs. The WTRU may determine a RB offset value for the WTRU based on a WTRU-ID modulo the maximum RB offset value, where the maximum value for the RB offset value may be based on at least one of the number of the scheduled RBs and the PT-RS density. The WTRU may then transmit or receive a signal with PT-RS based on the RB offset value.

摘要： A wireless transmit/receive unit (WTRU) may include one or more antennas and a first transceiver operatively coupled to the antennas. The one or more antennas and the first transceiver may be configured to receive a first signal from a network using zero energy from the WTRU. The one or more antennas and the first transceiver may be further configured to extract energy from the first signal. The first transceiver may be further configured to examine a separation between energy threshold events to decode an energy signature of the first signal. The first transceiver may be further configured to activate a second transceiver operatively coupled to the one or more antennas if the decoded energy signature matches a stored energy signature, wherein the second transceiver is powered by the WTRU. The one or more antennas and the second transceiver may be configured to receive a second signal from the network.

摘要： Methods and apparatus for targeted wake-up and frame enhancement for energy harvesting are disclosed. In one embodiment, a method performed by a station (STA) may compromise: receiving, during an energy detection state, a zero energy (ZE) frame from an access point (AP) that indicates a presence of an energy harvesting (EH) window; harvesting energy for a determined time duration during the EH window; and receiving, during an information decoding state, a data portion of the ZE frame based on a current stored energy of the STA being above a first threshold and a signal strength of the received ZE frame being above a second threshold.

摘要： A wireless transmit/receive unit (WTRU) may receive a physical downlink control channel (PDCCH) transmission in a WTRU-specific search space, with the PDCCH transmission including a sequence scrambled based on a first radio network temporary identifier (RNTI), the first RNTI associated with the WTRU, and the sequence including downlink control information (DCI) and a cyclic redundancy check (CRC). The WTRU may determine scheduling information for a physical downlink shared channel (PDSCH) transmission based on the DCI. Further, the WTRU may receive the PDSCH based on the scrambling information. Additionally, the first RNTI may be a WTRU-identifier (WTRU-ID). Also, the DCI and CRC may be scrambled by a second RNTI. Moreover, the WTRU may receive scrambling indication information indicating that scrambling of information in a PDCCH transmission by an RNTI may be used. Also, the PDCCH transmission may include the sequence on a condition that the scrambling indication information is received.

摘要： A wireless transmit/receive unit (WTRU) may receive configuration information indicating a set of physical channel frequency resources. The WTRU may receive downlink control information (DCI), and the DCI may include an indication of an allocation of at least a subset of the set of physical channel frequency resources. Further, the WTRU may determine a time period and one or more physical channel frequency resources from the subset of the set of physical channel frequency resources. The WTRU may transmit control information in a physical shared channel transmission using the determined one or more physical shared channel frequency resources during the determined time period. Also, the control information may include a WTRU-identifier (ID) associated with the WTRU. In an example, the control information may include a new data indicator (NDI) or a retransmission of previously transmitted control information. In a further example, the physical shared channel transmission may further include data.
