Abstract: Systems, methods, and instrumentalities are described herein for sidelink discovery, for example, associated with relays, e.g., NR relays. Discovery data may be transmitted, for example, to initialize communication between devices. Discovery data may be transmitted alone or multiplexed with other data (e.g., sidelink data). Discovery data with a high priority may be transmitted alone. Discovery data with a low priority may be multiplexed with other data (e.g., other data received within a duration of time). Discovery data may be multiplexed with other data that share the same destination identity. Resource allocation may be performed, for example, based on whether the discovery data is transmitted alone or multiplexed with other data.

Abstract: Systems, methods, and instrumentalities are disclosed herein associated with transmission of demodulation reference signals (DMRS) in wireless systems. DMRS symbols may be placed in a slot for channel estimation operations. For example, channel estimation performance may be enhanced based on using an increased number of DMRS symbols. Channel estimation enhancements may be performed by transmitting DMRS symbols in an extended slot, for example, to avoid data degradation (e.g., which may result from replacing data transmission symbols with DMRS symbols). An extended slot may be a slot that includes symbols spanning across multiple slots (e.g., two slots, consecutive slots), for example, such as a slot n and a slot n+1.

Abstract: Systems, methods, and instrumentalities are described herein for wireless transmit/receive unit (WTRU) power saving (e.g., for idle mode). A WTRU may determine a time window associated with one or more paging indicators. The WTRU may monitor for a paging indicator (e.g., a first paging indicator) in the time window. The WTRU may monitor for another paging indicator (e.g., a second paging indicator) in the time window. The WTRU may receive system information blocks (SIBs) if a wake up indication for the WTRU is received in a single paging indication and the paging indicator is the first paging indicator. The WTRU may monitor for a paging PDCCH at a monitoring occasion of a PO in a paging frame if the second paging indicator is received and includes an indication for the WTRU to wake up.

Abstract: Service information (e.g., enhanced broadcast service (eBCS) information) may be distributed. Service (e.g., eBCS) capabilities may be advertised (e.g., by an access point (AP)), for example, by broadcasting a public action frame. A public action frame may include per-service information. A public action frame may be transmitted on a per service basis. A public action frame may combine authentication information and service information. Enhanced broadcast service origin authentication may be performed on a per service basis (e.g., using origin authentication information to authenticate broadcast data frames for a consumed service). Origin authentication information may be common to frames associated with different services. Services may be consumed without querying a service originating device. Stations (e.g., with and without association with an AP) may report consumption or usage of services, Reporting may be unsolicited or solicited (e.g., in response to a request from an AP).

Abstract: A filter may be applied to a subset of components associated with a sample in a coding block. The output of the filter may be used to modify values for other component(s). For example, a filter may be applied to a selected (for example, dominant) component(s). The output of the filter may be used to modify a value for one of the other components (for example, non-dominant components). The output of the filter may be used, for example, after a weighting factor is applied to the filter output, to modify a value for another one of the other components. A joint refinement signal may be obtained, for example, as the filtered output signal minus the filter input signal of the selected component(s). A properly weighted version of the joint refinement signal may be applied to modify the other components.

Abstract: A WTRU may receive a slot format configuration (SFC) that indicates flexible symbols, uplink symbols, and downlink symbols. The WTRU may receive an uplink grant that is associated with the PUSCH transmission with repetitions. The received uplink grant may comprise a dedicated slot format indicator (SFI) and a resource map that indicates available resource block groups associated with the uplink symbols. The WTRU may identify an available uplink symbol based on the SFC, the SFI, and the resource map. The WTRU may identify, for the available uplink symbol, unavailable resource block groups based on the resource map. The WTRU may perform a PUSCH transmission repetition using the available uplink symbol, wherein the PUSCH transmission avoids the unavailable resource block groups.

Abstract: Systems, methods, and instrumentalities are disclosed for determining corresponding quality of service (QoS) information that are utilized in a first network for different data associated with a second network. The data may include control plane data and user plane data. A wireless transmit/receive unit (WTRU) may send a request to the first network to establish a first session with the first network for transmission of the data associated with a second network. The WTRU may receive one or more QoS mapping rules. The one or more QoS mapping rules may include information for mapping a first QoS indication to a packet comprising control plane data associated with the second network and information for mapping a second QoS indication to a packet comprising user plane data associated with the second network. The WTRU may use the one or more QoS mapping rules to determine a QoS indication for a packet.

Abstract: A WTRU may be configured with a plurality of monitoring patterns. The WTRU may determine, based at least in part upon the particular slot in the downlink channel, monitoring occasions for each of the plurality of monitoring patterns. The WTRU determines PDCCH candidates for each of the plurality of monitoring patterns and evaluates the total number of PDCCH candidates for each of the plurality of monitoring patterns against blind detection limits. The WTRU selects one of the plurality of monitoring patterns for the slot based at least in part on determining the PDCCH candidates for the selected monitoring pattern satisfy the blind detection limits.
