摘要： A method performed by a relay wireless transmit/receive unit (WTRU) includes receiving an indication of a change in state of a remote WTRU having a paging link with the relay WTRU, receiving a paging message from a network. The paging message includes a system information (SI) change indication, wherein the SI change indication indicates an availability of updated SI information from the network for the remote WTRU. The relay WTRU transmits the updated SI information to the remote WTRU based on the received indication of a change in state of the remote WTRU.

摘要： Methods and devices may be provided for aggregating component carriers in the licensed spectrum with at least one component carriers in the licensed exempt spectrum. Control information may be processed in a wireless transmit/receive unit (WTRU) while receiving and sending information on a primary component carrier (PCC) and a supplementary component carrier (SuppCC). A PCC subframe with a control portion and a data portion may be received. Resource assignment information associated with a downlink shared channel on the PCC may be embedded in the control portion of the subframe. Based on the resource assignment information on the PCC, resource assignment information associated with a downlink shared channel on the SuppCC may be identified in the data portion of the PCC subframe. A SuppCC subframe of the shared channel on the SuppCC may be processed as per the identified resource assignment information associated with the downlink shared channel on the SuppCC.

摘要： A wireless transmit receive unit (WTRU) may be configured to receive an indication/configuration from a network regarding changes in information related to the serving cell's identity (e.g., Physical cell identity (PCI), Cell Global Identity (CGI), etc.), which may contain additional information such as the conditions when this change becomes effective. Upon the reception of this indication, and if a condition is also specified, fulfillment of the condition, the WTRU may be configured to consider the new PCI/CGI as the serving cell's PCI/CGI, consider the old PCI as belonging to a neighbor cell, and/or may update the security keys that are used for encryption and integrity protection based on the new PCI.

摘要： Systems and methods are described generally related to the creation of a spectrum allocator (SA) function that can be used to dynamically assign/reassign the frequency of operation of a node operating in a wireless communication network. To permit LTE operation in license exempt (LE) bands, the radio resource management (RRM) system is enhanced to include an interface, which allows it to communicate with modules external to the RRM, such as a coexistence manager, policy engine and sensing toolbox.

摘要： A wireless transmit/receive unit (WTRU) may be configured for sidelink (SL) communication. The WTRU may receive SL discontinuous reception (DRX) configuration information from a peer SL WTRU. The SL DRX configuration information may comprise timer information. The timer information may comprise at least a SL on-duration timer, a SL inactivity timer, a SL hybrid automatic repeat request (HARQ) round trip time (RTT) timer, and a SL HARQ retransmission timer. The WTRU may apply the received SL DRX configuration information. The WTRU may report, on a condition that the WTRU has a connection to a network entity, to the network entity that the WTRU applied the received SL DRX configuration information.
