Abstract: Methods and systems for transmitting uplink control information in an LTE Advanced system are disclosed. A user device may determine whether uplink control information and/or available channels meet certain criteria and determine whether the uplink control information should be transmitted on a physical uplink control channel, a physical uplink shared channel, or both, based on the criteria. Criteria may include the size of the uplink control information (absolute size or relative to space available on a channel or a threshold value), the type of control information bits, the number of available (i.e., active or configured) component carriers, and the amount of power that may be required to transmit the uplink control information on more than one channel.

Abstract: A radio device may receive network assistance information relating to uplink channel access procedures, such as channel access types and related listen-before-talk techniques, via layer one signaling or higher layer signaling. For example, information may be provided via DCI, MAC CE, or RRC messaging, e.g,, received in a CORESET preceding the configured PRACH resources. Access procedures may be random access procedures, and may include indication via R.AR messaging. Access procedures may be triggered by a radio access point message, such as a PDCCH order or a handover request.

Abstract: A wireless transmit/receive unit (WTRU) may receive a physical downlink control channel (PDCCH) transmission in a WTRU-specific search space, with the PDCCH transmission including a sequence scrambled based on a first radio network temporary identifier (RNTI), the first RNTI associated with the WTRU, and the sequence including downlink control information (DCI) and a cyclic redundancy check (CRC). The WTRU may determine scheduling information for a physical downlink shared channel (PDSCH) transmission based on the DCI. Further, the WTRU may receive the PDSCH based on the scrambling information. Additionally, the first RNTI may be a WTRU-identifier (WTRU-ID). Also, the DCI and CRC may be scrambled by a second RNTI. Moreover, the WTRU may receive scrambling indication information indicating that scrambling of information in a PDCCH transmission by an RNTI may be used. Also, the PDCCH transmission may include the sequence on a condition that the scrambling indication information is received.

Abstract: Methods and apparatuses are described herein for prioritizing sidelink communication transmissions. In accordance with one example embodiment, an apparatus may transmit, to a network node, assistance parameters associated with sidelink communication comprising quality of service (QoS) parameters. The apparatus may receive, from the network node, configuration parameters associated with sidelink communication that comprise a logical channel configuration, a mapping of a QoS parameter to a sidelink radio bearer, and a mapping of the sidelink radio bearer to a sidelink logical channel. The apparatus may receive a sidelink resource grant and may select, based on the logical channel configuration, one or more sidelink logical channels to be served by the sidelink resource grant. The apparatus may transmit a generated a medium access control (MAC) protocol data unit (PDU), comprising data associated with the selected one or more sidelink logical channels, using the received sidelink resource grant.

Abstract: Systems, methods, and instrumentalities are disclosed for Uplink operation in LTE unlicensed spectrum (LTE-U). A wireless transmit/receive unit (WTRU) may receive licensed assisted access (LAA) configuration information, e.g., for a first cell from a second cell. The first cell may be associated with operation in an unlicensed band, and the second cell may be associated with operation in a licensed band. The WTRU may determine whether a first subframe is a sounding reference signal (SRS) subframe for the first cell. If the first subframe is an SRS subframe for the first cell, the WTRU may determine SRS resources for the first subframe and determine whether the WTRU is triggered to transmit an SRS transmission in the first subframe. If it is determined the WTRU is triggered to transmit the SRS transmission in the first subframe, the WTRU may transmit the SRS transmission on the SRS resources for the first subframe.
