摘要： A method and apparatus for use in a wireless transmit receive unit (WTRU) for receiving system information. A WTRU receives a broadcast signal from a gNB, wherein the broadcast signal includes system information. The WTRU determines configuration information associated with the received system information and the WTRU transmits a signal to the gNB using the determined configuration information associated with the received system information. The configuration information includes an indication regarding whether the WTRU is able to include any one or a combination of a request signal or a feedback signal in the signal transmitted to the gNB. The transmitted signal to the gNB may include a preamble that indicates system information block (SIB) request information. The transmitted signal to the gNB may include a control field that indicates additional SIB request information. The transmitted signal may provide feedback for the received system information. The WTRU then receives system information from the gNB in response to the transmitted signal. The received system information in response to the transmitted signal is one or more SIBs.

摘要： A method and apparatus are described for performing channel aggregation to communicate over a non-contiguous spectrum, such as television white space (TVWS), using a plurality of aggregated channels including a primary channel and at least one non-primary channel (e.g., a secondary channel, a tertiary channel or a quaternary channel). Carrier sense multiple access (CSMA) may be performed on the primary channel to obtain access to the primary channel. After waiting an arbitration interframe space (AIFS) and potentially performing backoff on the primary channel, the aggregated channels may be used for transmission. A buffer controller may be used to create, for each of a plurality of access classes (ACs), a logic buffer for each of the channels. A frame controller may be used to provide the buffer controller with aggregated medium access control (MAC) protocol data unit (A-MPDU) frame information, and control aggregation and fragmentation processes.

摘要： Described herein are methods, metrics and apparatus for bandwidth allocation for cognitive radio. Information that needs to be passed between different components of a dynamic spectrum management (DSM) system for dynamic bandwidth allocation along with the corresponding interfaces is identified. Methods and associated metrics for measuring network performance, evaluating channel sensing results and handling various bandwidth allocation scenarios are presented. Also provided is an admission control mechanism for quality of service support. Alternate channel monitoring maybe performed in the background so that when a new channel is needed, an alternate channel may be immediately allocated and service disruption to the DSM system is reduced. A channel may be dynamically assigned as the primary channel in multiple channel scenarios to support tasks such as transmission of acknowledgment frames. Hybrid mode devices that may access a television white space (TVWS) database and perform spectrum sensing are also described.

摘要： A method, implemented in a first WTRU comprises a step of transmitting, to a network node, a first message comprising first information indicating a scheduling request for sidelink transmission resources. The method comprises a step of receiving, from the network node, a second message comprising second information indicating the sidelink transmission resources based on the first message. The method comprises a step of transmitting, to a second WTRU, sidelink data, based on the received sidelink transmission resources. The method comprises a step of receiving, from the network node, a third message comprising third information indicating sidelink retransmission resources for the sidelink data transmission; and a step of transmitting, to the second WTRU, the sidelink data based on the received retransmission resources.

摘要： A WTRU may include a memory and a processor. The processor may be configured to receive beam grouping information from a gNB or transmission and reception point (TRP). The beam grouping information may indicate a group of beams that the WTRU may report using group-based reporting. The group-based reporting may be a reduced level of reporting compared to a beam-based reporting. The group-based report may include measurement information for a representative beam. The representative beam may be one of the beams in the group or represents an average of the beams in the group. Alternatively, the representative beam may be a beam that has a maximum measurement value compared to other beams in the group. The group-based report may include a reference signal received power (RSRP) for the representative beam and a differential RSRP for each additional beam in the beam group.

摘要： Systems and methods are provided for coexistence management service for licensed and unlicensed spectrum sharing. A coexistence system may include a coexistence manager (CM) that may provide resource allocation services for a coexistence enabler (CE). CMs may negotiate with each other to resolve coexistence issues via directly or indirectly through a coexistence discovery and information server (CDIS). A channel may be exclusively used by a CE network. The networks may mitigate interference by avoiding use of the same channels. A channel may be shared by multiple CE networks. In co-channel sharing, the networks may mitigate interference via power management. Bidding processes may be implemented directly via competing CMs, for example via open or silent token auction. Bidding processes among competing CMs may be managed by a third party entity, for example a CDIS, for example via open or silent token auction.

摘要： A wireless network may implement a reduced bandwidth for control information transmitted and/or received on the wireless network. The reduced bandwidth may be used to avoid interference that may be detected from an in-band or adjacent channel. The reduced bandwidth may be used for transmission and/or reception of control information on a cellular or Wi-Fi channel. An eNB or an access point (AP) may signal to a wireless transmit/receive unit (WTRU) information associated with the reduced control channel, such as the power and/or the location of the channel in a frequency band. The control channel may be shifted to avoid a change in interference.

摘要： Described herein are methods, apparatus and architecture for dynamic spectrum management (DSM) including protocol stacks, logical entities and functionalities that support DSM operation in opportunistic spectrum such as television white space (TVWS). The architecture supports aggregating bandwidth at the internet protocol (IP) layer over licensed and opportunistic bands as well as noncontiguous spectrum aggregation at the medium access control (MAC) layer. The control plane protocol stack includes a multi network transport protocol (MNTP), a channel management (CM) protocol, a policy protocol, a medium access control (MAC) entity, a physical entity and an air interface, all of which are configured to allocate, monitor, and update aggregated spectrum resources with respect to a DSM client.
