  • Publication number: 20200169999
    Abstract: A method and an apparatus for wireless transmission using multiple uplink carriers are disclosed. A wireless transmit/receive unit (WTRU) may transmit via a primary uplink carrier data, pilot and control channels for uplink transmissions on both uplink carriers, and transmit a data channel and a pilot channel via a secondary uplink carrier. Alternatively, the WTRU may transmit via a primary uplink carrier data, pilot, and control channels for uplink transmission on the primary uplink carrier, and transmit via a secondary uplink carrier data, pilot, and control channels for uplink transmissions on the secondary uplink carrier. Each uplink carrier may be associated with at least one specific downlink carrier such that the WTRU applies control information received on a downlink carrier to uplink transmissions on an uplink carrier associated with the downlink carrier on which the WTRU receives the control information.

    Abstract: Methods and apparatuses are provided for generating a protocol data unit (PDU). An apparatus may comprise a processor configured to provide a medium access control (MAC) entity and a segmentation entity. The MAC entity may indicate an amount of data associated with the segmentation entity to be multiplexed by the MAC entity. The segmentation entity may segment, based on the indicated amount of data, a service data unit (SDU) into a segment, and the MAC entity may multiplex the segment into a MAC protocol data unit (PDU). The MAC PDU may include a field that indicates whether the segment is included and whether the segment is a last segment. The apparatus may further comprise a transmitter configured to transmit the MAC PDU.

  • Patent number: 10645690
    Abstract: A wireless transmit/receive unit (WTRU) includes a receiver and a processor configured to receive information from a network node indicating an assignment of periodic time intervals to transmit sounding signals. The WTRU includes a transmitter and the processor configured to transmit sounding signals to the network node in the assigned periodic time intervals in response to the received information. The WTRU does not transmit any data at a same time that the WTRU transmits the sounding signals. The transmitted sounding signals from the WTRU are distinguishable from sounding signals from other WTRUs.

  • Patent number: 10560852
    Abstract: A method and apparatus of performing discontinuous reception (DRX) and downlink inter-frequency and inter-radio access technology (RAT) measurements in CELL_FACH state are disclosed. While in DRX mode, a wireless transmit/receive unite (WTRU) may perform inter-frequency and inter-RAT measurements in a measurement occasion that fall into a DRX period. The WTRU may take the measurements on first predetermined number of frame in which a DRX frame would coincide after a last reception frame if DRX operation was ongoing. The WTRU may periodically wake up for downlink reception in CELL_FACH state in accordance with common DRX pattern that is common to all WTRUs in a cell or may wake up from DRX upon reception of the order and receiving a common traffic.

  • Publication number: 20200044781
    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.

  • Patent number: 10531366
    Abstract: Disclosed herein are embodiments for Machine Type Communication (MTC). The techniques disclosed may reduce signaling by transmitting MTC data over control planes and avoiding a full cycle of connection procedures typically required for transmission. MTC data may be directly appended to a control plane message. In addition, in order to reduce the signaling load, a WTRU may autonomously release the connection without being told by the network. Techniques may be used to indicate a network provider's machine type communication (MTC) capability. The MTC services or capabilities that may be provided by a respective network operator may be communicated to a WTRU.

  • Publication number: 20190349918
    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.

  • Patent number: 10469208
    Abstract: Methods and apparatus utilize hybrid automatic repeat request (HARQ) transmissions and retransmissions that are usable on multiple carriers, i.e. joint HARQ processes. For example, a downlink (DL) shared channel transmission of a joint HARQ process is received on one of the carriers. A first part of an identity of the joint HARQ process is determined by using HARQ process identity data received on a shared control channel. A second part of the joint HARQ process identity is determined using additional information. The joint HARQ process identity is then determined by combining the first part and the second part. A WTRU is provided that is configured to receive the DL shared channel and to make the aforementioned determinations. A variety of other methods and apparatus configurations are disclosed for utilizing joint HARQ processes, in particular in the context of DC-HSDPA.

  • Patent number: 10382181
    Abstract: A method and apparatus for acknowledge mode data (AMD) re-segmentation are disclosed. An AMD protocol data unit (PDU) is generated from at least one RLC SDU. The AMD PDU size is within a flexible maximum AMD PDU size. The original AMD PDU is stored in a retransmission buffer, and transmitted. If transmission of the original AMD PDU fails and the original AMD PDU size is larger than an updated maximum AMD PDU size, the original AMD PDU is segmented to segmented AMD PDUs. If transmission of one of the segmented AMD PDUs fails, the original AMD PDU may be re-segmented to smaller size AMD PDUs.
