  • Patent number: 11109257
    Abstract: A wireless transmit/receive unit (WTRU) may receive configuration information indicating a plurality of sets of resource elements (REs). Each of the plurality of sets of REs may be associated with a Channel-State-Information Reference Signal (CSI-RS) configuration. Also, the WTRU may receive a request in a Downlink Control Information (DCI) signal, in a first time unit, to receive at least one CSI-RS, in at least one set of the plurality of sets of REs, in the first time unit, to perform a measurement and to report the measurement; and the request may indicate the at least one set of the plurality of sets of REs. Further, the WTRU may receive the at least one CSI-RS, in the at least one set of the plurality of sets of REs, in the first time unit, according to the request. Moreover, the WTRU may perform the measurement of the at least one CSI-RS.

  • Patent number: 11102711
    Abstract: In a network comprising both fixed transmission points and mobile transmission points, the transmission points may transmit discovery reference signals that allow WTRUs to detect and/or synchronize to the transmission points. The fixed and mobile transmission points may transmit discovery reference signals with different characteristics that allow the WTRUs to distinguish between fixed and mobile transmission points. The mobile transmission points may also transmit a separate maintenance reference signal that allows WTRUs to maintain a connection with the mobile transmission point. For networks in which fixed a mobile transmission points operate in different frequency bands, the mobile transmission points may also periodically transmit discovery beacon signals in the frequency band of the fixed transmission points to allow discovery. Conditions may be imposed on WTRUs before the WTRU will transmit to the network a measurement report reporting on a potential transmission point to which it may be switched.

  • Publication number: 20210243808
    Abstract: A WTRU may be configured to perform radio link monitoring (RLM) based on RLM reference signals (RLM-RSs) transmitted in a cell operating in an unlicensed spectrum. The WTRU may evaluate a radio link failure (RLF) status for the cell using a first RLM criteria based on the RLM-RSs. A transmission instance of the RLM-RSs may be skipped, for example, due to a listen before talk (LBT) failure at a gNodeB (gNB). The WTRU may adapt or change the first RLM criteria and/or evaluate the RLF status of the cell operating in the unlicensed spectrum using a second RLM criteria based on determining that the transmission instance of the RLM-RSs was skipped. The first RLM criteria may correspond to a first RLM process that utilizes a first set of RLM parameters. The second RLM criteria may correspond to a second RLM process that utilizes a second set of RLM parameters.

  • Publication number: 20210176710
    Abstract: A wireless transmit/receive unit (WTRU) may receive/transmit data by employing a discontinuous reception cycle, which may include an awake state and a sleep state. For example, while in an awake state, a WTRU may monitor a PDCCH for a subset of time instances. During the remaining time instances, the WTRU may enter a sleep state, in which the WTRU may switch its receiving circuitry off (e.g., to reduce power consumption). A WTRU may receive (e.g., may expect to receive) one or more transmissions, during an awake state, before entering a sleep state. The durations of an awake state and/or the durations of subsequent sleep states may be determined based on whether the WTRU receives a transmission during the awake state and/or what the transmission was for. The WTRU may modify the value of a sleep state timer based on previous sleep state and/or awake state timer values.

  • Patent number: 11032053
    Abstract: A wireless transmit/receive unit (WTRU) may receive a plurality of transport blocks over a plurality of configured carriers. The WTRU may generate hybrid automatic repeat request (HARQ)-acknowledgment (ACK) feedback for the plurality of transport blocks, channel state information (CSI) feedback for at least one of the plurality of configured carriers, and a cyclic redundancy check (CRC). Further, the WTRU may generate a feedback message that includes a number of HARQ-ACK feedback bits for the HARQ-ACK feedback, a number of CSI feedback bits for the CSI feedback, and a number of CRC bits for the CRC. The WTRU may then determine a power to be used for a Physical Uplink Control Channel (PUCCH) transmission based on the number of HARQ-ACK feedback bits, the number of CSI feedback bits, and the number of CRC bits. Moreover, the WTRU may transmit the feedback message in the PUCCH transmission at the determined power.
