  • Publication number: 20240121652
    Abstract: A method implemented by a Wireless Transmit/Receive Unit (WTRU) includes receiving a DeModulation Interference Measurement (DM-IM) resource, determining an interference measurement based on the DM-IM resource, and demodulating a received signal based on the interference measurement. An interference is suppressed based on the interference measurement. At least one DM-IM resource is located in a Physical Resource Block (PRB). The DM-IM resource is located in a PRB allocated for the WTRU. The DM-IM resource is a plurality of DM-IM resources which form a DM-IM pattern, and the DM-IM pattern is located on a Physical Downlink Shared Channel (PDSCH) and/or an enhanced Physical Downlink Shared Channel (E-PDSCH) of at least one Long Term Evolution (LTE) subframe. The DM-IM resources are different for different Physical Resource Blocks (PRB) in the LTE subframe. The DM-IM is located in a Long Term Evolution (LTE) Resource Block (RB), and the DM-IM pattern is adjusted.

  • Publication number: 20240072866
    Abstract: Systems, methods, and instrumentalities are described herein that may be used for transmission of one or more DCI, CSI-RS and/or CSI reports. A wireless transmit/receive unit (WTRU) may receive a DCI that includes information indicating two channel state information reference signal (CSI-RS) resources and four CSI reporting resources. Each CSI-RS resource may be associated with two CSI reporting resources. The WTRU may monitor a first CSI-RS resource for a CSI-RS. If the WTRU does not identify the CSI-RS in the first CSI-RS resource, the WTRU may monitor a second CSI-RS resource for the CSI-RS. The WTRU may receive the CSI-RS on the first CSI-RS resource or the second CSI-RS resource. The WTRU may determine availabilities of the first and/or the second CSI reporting resource associated with the CSI-RS resource on which the WTRU received the CSI-RS. The WTRU may transmit a CSI report on an available CSI reporting resource.

  • Publication number: 20240063950
    Abstract: A wireless transmit/receive unit (WTRU) may receive a downlink transmission and send a physical uplink control channel (PUCCH) transmission in each resource block (RB) of an interlace of a plurality of RBs in an active bandwidth part (BWP). A base sequence is mapped to the PUCCH transmission repetitively, once to each RB of the plurality of RBs of the interlace, using a different cyclic shift of the base sequence for each RB. Each different cyclic shift of the base sequence in the PUCCH transmission to each RB is a function of a RB index of the respective RB. The PUCCH transmission indicates either an acknowledgement (ACK) or a negative ACK (NACK) of the received downlink transmission.

  • Publication number: 20240056221
    Abstract: Systems, methods and instrumentalities are disclosed for decoding data. For example, it may be determined, in a current slot, whether data received in a previous slot is decoded successfully. The data received in the previous slot may be included in a Physical Downlink Shared Channel (PDSCH). If the data received in the previous slot is not decoded successfully, preemptive multiplexing information may be detected in a first search space. The data received in the previous slot may be decoded, for example, using detected preemptive multiplexing information. The preemptive multiplexing information may be of a current slot. The preemptive multiplexing information may be comprised in a first DCI. A second search space of the current slot may be searched. For example, the second search space may be searched for a second DCI. The first DCI and the second DCI may be different.

  • Patent number: 11876747
    Abstract: Devices and methods are disclosed for a physical sidelink control channel (PSCCH) design in new radio (NR). A wireless transmit receive unit (WTRU) for sidelink communication may receive a resource pool identity (ID). Further, the WTRU may determine whether to include information related to demodulation reference signal (DM-RS) density for a sidelink transmission in sidelink control information (SCI) based on the resource pool ID. On a condition that the information related to DM-RS density is to be included in the SCI, the WTRU may transmit the SCI including the information related to DM-RS density. Also, the SCI may be associated with a PSSCH. Accordingly, the WTRU may transmit the sidelink transmission on the PSSCH with one or more DM-RSs at a first DM-RS density based on the information related to DM-RS density.

  • Publication number: 20230362941
    Abstract: Methods and systems for transmitting uplink control information and feedback are disclosed for carrier aggregation systems. A user equipment device may be configured to transmit uplink control information and other feedback for several downlink component carriers using one or more uplink component carriers. The user equipment device may be configured to transmit such data using a physical uplink control channel rather than a physical uplink shared channel. The user equipment device may be configured to determine the uplink control information and feedback data that is to be transmitted, the physical uplink control channel resources to be used to transmit the uplink control information and feedback data, and how the uplink control information and feedback data may be transmitted over the physical uplink control channel.

  • Publication number: 20230336316
    Abstract: A wireless transmit receive unit (WTRU) may be configured to transmit uplink control information such as Hybrid Automatic Retransmission Request (HARQ) Acknowledgement or Negative Acknowledgement (ACK/NACK) using a sequence. The HARQ ACK/NACK may comprise one bit or two bits of information, and the WTRU may use a cyclic shift of the sequence to transmit the HARQ ACK/NACK. The WTRU may use different cyclic shifts of the sequence to transmit different HARQ ACK/NACK values and the cyclic shifts may be separated from each other in a manner to facilitate the transmissions. The WTRU may be further configured to receive, from a physical downlink control channel (PDCCH), an indication of a resource block for transmitting the HARQ ACK/NACK.

  • Publication number: 20230246752
    Abstract: 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 UE-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 of legacy control channels may affect the demodulation and or decoding methods. The method may be implemented at a WTRU.

  • Publication number: 20230232456
    Abstract: Methods, systems, and devices for channel access and listen-before-talk approaches for new radio operation in unlicensed bands and/or licensed bands. A gNB and a wireless transmit/receive unit (WTRU) may operate in unlicensed spectrum. The gNB may perform listen-before-talk operation, and when successful, may send a downlink control channel with a slot format indication (SFI) to the WTRU. There may also be a handshaking procedure with an exchange of a request to transmit (RTT) and a request to receive (RTR). Prior to receiving the downlink channel, the WTRU may monitor search spaces at a first level, and once the downlink channel is received the WTRU may monitor search spaces at a second level. At the end of transmission, the WTRU may revert back to monitoring search spaces at the first level. In one example, the first level may be a mini-slot level and the second level may be a slot level.
