  • Publication number: 20240147477
    Abstract: A wireless transmit receive unit (WTRU) may be configured to receive configuration information comprising an indication of a first control channel monitoring configuration, a second control channel monitoring configuration, and a threshold value. The WTRU may monitor for control channel transmissions in accordance with the first control channel monitoring configuration. The WTRU may receive a first set of one or more protocol data units (PDUs). The WTRU may determine that at least one PDU remained in an application buffer for a period of time that is greater than the threshold value, or a remaining delay budget associated with the first set of one or more PDUs is less than a threshold. The WTRU may monitor for control channel transmissions in accordance with the second control channel monitoring configuration. The WTRU may transmit an indication that the WTRU has switched to the second control channel monitoring pattern.

  • Patent number: 11973746
    Abstract: Capillary network devices (i.e., IMSI-less devices) may connect to an EPC through a home WLAN. A WLAN can be configured by the homeowner to accept responsibility for the traffic or a WLAN can indicate to a network that it will allow the traffic if the traffic is sponsored by an application server or if it is compensated for the traffic by the network operator. Where an IMSI-less device has a business relationship with a network operator, a WLAN can allow the device to authenticate with the network and obtain a device identifier from the network. Where an IMSI-less device has a business relationship with a SCS that has a business relationship with the network operator, the WLAN can allow the device to authenticate with the network.

  • Patent number: 11973597
    Abstract: Systems and method are specified to improve the reception of UL transmission, for example in power or coverage limited situations. A WTRU may modify procedures to increase the available signal energy for reception at an eNB and/or to make more efficient use of the available signal energy at the receiver for processing UL transmissions. Example methods for increasing UL link coverage may include modifying HARQ timing (e.g., shorter HARQ), using longer TTIs, use of dedicated PUSCH allocations, use of new PUSCH modulations, enhanced reference signal design, UL macro diversity reception for PUSCH, utilizing protocol reduction techniques, ensuring in-order packet delivery, and/or utilizing a configuration for coverage limited/power limited modes of operation. The proposed methods may be applied individually or in any combination.

  • Publication number: 20240129063
    Abstract: A polar code may be initially divided into multiple polar component codes where the features of these component codes, such as the number of component codes and the size of the component codes, are determined based on parameters such as the number of available timing units within a transmission interval, interleaving depth, and decoder capability. For each selected component code, the order of code bit generation and their indexes may be determined. The determined indexes may be assigned into different, unique groups according to the order of code bit generation. An interleaving operation may be configured and then executed according to the determined index grouping. In the transmission phase, the code bits may be transmitted based on the identified order of the bit generation in the component polar codes, such as the determined index grouping.

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.

  • Publication number: 20240129841
    Abstract: Cell detection information, such as cell identity, frequency, dormant/active mode, etc. may be determined. This cell detection information may be reported based on properties of a received Auxiliary Synchronization Signal (AuSS) or discovery signal. The received signal may be processed as a function of its timing, for example, with respect to timing of a serving cell. A WTRU may obtain cell detection information for a neighbor cell. A cell may also be detected by surrounding WTRUs. A WTRU may determine timing of cell reactivation from a detected property of the AuSS or discovery signal. A WTRU may trigger an RRC procedure upon selecting a dormant but temporarily reactivated cell. An eNB may transmit AuSS for a dormant cell based on detection of signals received from neighbor cells. Quasi-colocation (QCL) demodulation may be performed based on the detected signal. The on/off state of a cell may be indicated.
