摘要: A WTRU may receive downlink control information (DCI) indicating a start of a frame. The DCI may be received on a control channel, such as the Physical Downlink Control Channel (PDCCH) from an eNB, base station, AP, or other infrastructure equipment operating in a wireless communications system. The WTRU may decode the DCI and may determine a transmit time interval (TTI) duration, which may be expressed in terms of an integer number of basic time intervals (BTIs). The WTRU may determine a downlink (DL) transmission portion and assignment and an uplink (UL) transmission portion and UL grant based on the received DCI. Additionally, the WTRU may determine the start of the UL portion based on an offset (toffset). The WTRU may receive data in a DL portion of the frame and may transmit in an UL portion of the frame based on the determined UL grant and TTI duration.

摘要: A WTRU may determine that a LTE cell at least partially overlaps in frequency with an NR cell. The WTRU may determine that an NR transmission is to be received within a set of resources that are included in at least a portion of the NR cell that at least partially overlaps with the LTE cell. The WTRU may determine a subset of resources within the set of resources that correspond to an LTE common transmission. The WTRU may receive the NR transmission within the set of resources. The NR transmission may not be included in the subset of resources that correspond to the LTE common transmission. The LTE common transmission may include one or more of a common control signal, a cell-specific broadcast signal, cell-specific reference signals, a physical downlink control channel, a primary synchronization signal, a secondary synchronization signal, and/or a channel state information reference signal.

摘要: In a network comprising both fixed transmission points and mobile transmission points, the transmission points may transmit discovery reference signals that allow WTRUs to detect and/or synchronize to the transmission points. The fixed and mobile transmission points may transmit discovery reference signals with different characteristics that allow the WTRUs to distinguish between fixed and mobile transmission points. The mobile transmission points may also transmit a separate maintenance reference signal that allows WTRUs to maintain a connection with the mobile transmission point. For networks in which fixed a mobile transmission points operate in different frequency bands, the mobile transmission points may also periodically transmit discovery beacon signals in the frequency band of the fixed transmission points to allow discovery. Conditions may be imposed on WTRUs before the WTRU will transmit to the network a measurement report reporting on a potential transmission point to which it may be switched. Such conditions may include the speed of a WTRU relative to the transmission point with which it is currently associated, the speed of the WTRU relative to the newly discovered transmission point or both.

摘要: Systems, methods, and instrumentalities are disclosed for a wireless transmit/receive unit (WTRU) receiving a first set of one or more initial access signals from a Transmission/Reception Point (TRP), wherein the first set of one or more initial access signals indicates that the TRP is in a dormant state, sending an echo signal to the TRP, wherein one or more transmission parameters of the echo signal are derived from the first set of one or more initial access signals received from the TRP, monitoring for a second set of one or more initial access signals from the TRP after transmitting the echo signal, and receiving the second set of one or more initial access signals, the second set of initial access signals comprising information associated with accessing the TRP. Sets of one or more initial access signals may be received from a plurality of TRPs in an area. The second set of one or more initial access signals may be received from a TRP that is closest to, or has a strongest signal strength for transmitting to, the WTRU.

摘要: A receiver bandwidth adaptation for radio access technologies (RATs) may be for a New Radio (NR) or 5G flexible RAT. A WTRU control channel {e.g., receiver) bandwidth may change, for example, based on monitoring a downlink channel for an in indication using a bandwidth (BW) associated with a first BW configuration. The indication may include a signal to change the receiver BW. The WTRU may change the receiver BW associated with the first BW configuration to a second BW configuration when the WTRU receives the indication on a downlink (DL) channel. The WTRU may perform one or more measurements associated with the second BW configuration in response to the change of the receiver BW to the second BW configuration. The WTRU may transmit measurement information to a network entity. The WTRU may receive a DL transmission from the network using the second BW configuration.

摘要: One or more techniques for beamformed paging are disclosed. A transmission/reception point (TRP) may transmit a paging inquiry signal using beam sweeping in a paging inquiry (PI) block with a different time, frequency resource set and/or sequence configuration associated with the same paging occasion (PO), for example, to randomize and/or distribute WTRUs into different monitoring groups. A WTRU may transmit an uplink paging inquiry response indicating a downlink beam for a paging data transmission and/or a WTRU ID. A downlink control and/or a data channel transmission may be triggered by a paging inquiry response transmission. Paging downlink control information may be transmitted in a WTRU-specific control channel, which may contain CRC bits masked by a temporary paging identity, e.g., based on a WTRU ID that may be reported in a paging inquiry response transmission. A WTRU paging procedure may be based on a paging inquiry signal and/or response transmission.

摘要: Systems, methods, and instrumentalities may be disclosed for implementing a flexible radio access communication system. A flexible radio access communication system may be supported using spectrum of varying size, including aggregation of non-adjacent carriers in the same and/or in different frequency bands. A wireless transmit/receive unit (WTRU) may receive a first transmission via a common downlink control channel. The first transmission may include first control information. The first control information may include information regarding the configuration of a first dedicated downlink control channel of one or more dedicated control channels. The WTRU may receive a second transmission via the first dedicated downlink control channel of the dedicated control channels. The second transmission may include second control information. The second control information may be associated with a transmission of a first transmission type. The dedicated downlink control channels may be used for providing control information associated with different types of transmissions.

摘要: A method and apparatus for selecting a resource for transmission may be performed by a WTRU. The method may comprise determining a priority of a data packet and determining a CBR of a resource pool. The WTRU may set a backoff counter to an initial backoff value, in accordance with at least one of the priority of the packet or the CBR. A CCA may be performed in a plurality of resource slots to determine whether the resource slots are available. The backoff counter may be decreased by the number of available resources in each slot. When the backoff counter reaches a threshold value, which may be set at 0, the resource for transmission may be randomly selected. The WTRU may then transmit data to another WTRU on the randomly selected resource.

摘要: Methods to perform, maintain and report measurements on a transmission-reception point (TRP) using limited reference signal transmission are described herein. The mobility measurement reports may utilize physical channels. Methods to obtain measurements on neighbor TRPs using limited RS transmissions are also described herein. Random-Access procedures to enable the addition of a neighbor TRP or handover without requiring higher layer signaling (and possibly without an interface between source and target TRP) are also described herein. New triggers to perform RA in order to decrease handover latency are also described herein. Wireless Transmit/Receive Unit (WTRU) behavior upon receiving RAR from multiple possible TRPs are also described herein. For example, a WTRU may store RAR information and use it later in an interrupted RA procedure.
