  • Publication number: 20240057040
    Abstract: ePDCCH may be provided. For example, a WTRU may receive a configuration for monitoring an ePDCCH resource. Based on the configuration, the WTRU may be configured to monitor and may monitor the ePDCCH resource on a particular subframe. Additionally, a WTRU may derive an aggregation level for a subframe associated with an aggregation level number NAL. The WTRU may transmit or monitor an ePDCCH using the aggregation level associated with the NAL for the subframe. A WTRU may also receive a reference signal. The WTRU may then determine the type of reference signal received. The WTRU may perform a demodulation of the PDSCH or ePDCCH using a demodulation timing based on the determined type. The ePDCCH or PDSCH may also be monitored or received by identifying a demodulation reference timing implicitly based on a location of one or more ePDCCH resources where the WTRU may receive DCI.

  • Publication number: 20240057214
    Abstract: Current wireless networks do not allow machine type communication (MTC) devices to have long discontinuous reception (DRX) cycles or sleep lengths. A long DRX cycle may allow MTC systems and devices to operate with much longer DRX/Sleep cycles/periods. This may facilitate the MTC operations for infrequent system access or infrequent system reaching (e.g. paged once in a week) with no or low mobility and may allow MTC devices to sleep for a long time with low power consumption.

  • Publication number: 20240056276
    Abstract: A receiver bandwidth adaptation for radio access technologies (RATs) may be for a New Radio (NR) or 5G flexible RAT. A WTRU control channel (e.g., receiver) bandwidth may change, for example, based on monitoring a downlink channel for an indication using a bandwidth (BW) associated with a first BW configuration. The indication may include a signal to change the receiver BW. The WTRU may change the receiver BW associated with the first BW configuration to a second BW configuration when the WTRU receives the indication on a downlink (DL) channel. The WTRU may perform one or more measurements associated with the second BW configuration in response to the change of the receiver BW to the second BW configuration. The WTRU may transmit measurement information to a network entity. The WTRU may receive a DL transmission from the network using the second BW configuration.

  • Patent number: 11895663
    Abstract: Methods and apparatus for wireless transmit/receive unit (WTRU) power control are described. A method includes receiving a time domain resource allocation (TDRA) list configuration including entries, each including a resource allocation that includes a slot offset value. L1 signaling is received indicating a minimum slot offset value. Downlink control information (DCI) is decoded on a physical downlink control channel in a slot. An index is obtained from the decoded DCI, identifying an entry in the TDRA list. A particular slot offset value identified by the index is retrieved from the TDRA list and compared with the minimum slot offset value. If the particular slot offset value is less than the minimum slot offset value, the entry is invalid. If the particular slot offset value is greater than or equal to the minimum slot offset value, a physical downlink shared channel is received.
