摘要： A method implemented by a Wireless Transmit/Receive Unit (WTRU) includes receiving a DeModulation Interference Measurement (DM-IM) resource, determining an interference measurement based on the DM-IM resource, and demodulating a received signal based on the interference measurement. An interference is suppressed based on the interference measurement. At least one DM-IM resource is located in a Physical Resource Block (PRB). The DM-IM resource is located in a PRB allocated for the WTRU. The DM-IM resource is a plurality of DM-IM resources which form a DM-IM pattern, and the DM-IM pattern is located on a Physical Downlink Shared Channel (PDSCH) and/or an enhanced Physical Downlink Shared Channel (E-PDSCH) of at least one Long Term Evolution (LTE) subframe. The DM-IM resources are different for different Physical Resource Blocks (PRB) in the LTE subframe. The DM-IM is located in a Long Term Evolution (LTE) Resource Block (RB), and the DM-IM pattern is adjusted.

摘要： A transmitting wireless transmit/receive unit (Tx WTRU) may receive configuration information that indicates one or more parameters. The one or more parameters may be associated with resource selection. The Tx WTRU may determine a first resource selection window and a second resource selection window. The first resource selection window may be associated with an active time of a receiving wireless transmit/receive unit (Rx WTRU). The second resource selection window may be associated with an inactive time of the Rx WTRU. The Tx WTRU may determine a first number of candidate resources associated with the first resource selection window. The Tx WTRU may determine a first number of candidate resources associated with the second resource selection window. In examples, the Tx WTRU may increase the first number of candidate resources associated with the first resource selection window to a second number of candidate resources associated with the first resource selection window.

摘要： Methods, apparatus, systems, architectures and interfaces for compressing hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback bits performed by a wireless transmit/receive unit (WTRU) receiving a transmit block (TB) including code block group (CBG) data are provided. The method includes receiving, by the WTRU, information associated with transmitting compressed HARQ-ACK feedback information, receiving, by the WTRU, a TB; determining, by the WTRU, a countdown downlink assignment index (CD_DAI) associated with the received TB; generating, by the WTRU, the compressed HARQ-ACK feedback information by compressing HARQ-ACK feedback bits associated with the received TB; and on condition that: (1) the CD_DAI is equal to zero or (2) the WTRU determines to provide feedback information, transmitting the compressed HARQ-ACK feedback information.

摘要： Systems, methods, and instrumentalities are disclosed for connectivity supervision and recovery. A WTRU may supervise its capability to transmit and receive data, including in the absence of a control channel (e.g. grant-less transmission). A supervision framework may permit a WTRU to supervise, for example, quality of a feedback channel, quality of reciprocal resources and/or transmission attempts. A supervision process may be a function of a control channel structure or WTRU state. A supervision process may be associated with a quality of service. A supervision process may be based on WTRU transmission for energy/resource efficient operation. Multiple Recovery procedures may be defined. A recovery procedure may be a function of a supervision process. A recovery procedure may be optimized for low latency services. Recovery procedures may involve dedicated resources for recovery, transition to light connection, grant-less resource, etc. User plane recovery may include reuse of layer 2 context, data replication to companion MAC instances, etc. Control plane recovery may use RAN paging, WTRU triggered multi-connectivity, etc. A recovery procedure for a supervision process associated with a beam process may include WTRU triggering beam training/beam refinement, etc.

摘要： A wireless transmit/receive unit (WTRU) determines PDCCH candidates. For a slot, the WTRU determines a number of valid PDCCH candidates associated with at least one search space based on a number of designated search spaces associated with the WTRU in the slot, a type of the search space, a priority associated with the search space, a number of required CCE channel estimates associated with the search space, a maximum number of PDCCH candidates in a slot, and a number of control resource sets (CORESETs) associated with the slot. The WTRU may then attempt to decode CCEs in the at least one search space to recover a PDCCH associated with the WTRU. The WTRU may drop PDCCH candidates from the search space when the number of PDCCH exceeds a maximum value.

摘要： User equipment (UE) may detect a disaster condition, and the resolution thereof, based on broadcast information, RRC messaging, NAS messaging, the ability to connect to an allowable PLMN, and indications from forbidden PLMNs. In a disaster condition, a UE may perform an enhanced PLMN selection procedure wherein, for example, the UE will not consider PLMNs that are in a disaster situation if the disaster situation applies to a current location of the UE, prioritize forbidden PLMNs for disaster roaming connection. For disaster roaming connection, the UE may be configured by an otherwise forbidden PLMN with information about what services the UE can access and what type of authentication procedure the network is able to perform with UE. Upon detecting that the disaster condition is over, the UE move back to an allowable PLMN.

摘要： Systems, methods, and instrumentalities (e.g. aspects of entities, interfaces and procedures in a wireless transmit/receive unit (WTRU) and/or network layers L1, L2, l3) are disclosed for low latency medium access control (MAC) protocol data unit (PDU) assembly in wireless systems, such as 5G flexible radio access technology (RAT) (5gFLEX). Latency may be reduced, for example, by WTRU determination of network transmission parameters and signaling prior to a transmission grant. A WTRU may receive a modulation and coding scheme (MCS), resource range, etc. prior to a grant, e.g., for use in future grants. Data blocks may be incrementally created/encoded prior to a grant. Data units may be segmented, assembled and multiplexed, for example, based on data block sizes that allow MAC and radio link control (RLC) processing prior to a grant. Flexible grant sizes may be provided for early generation of transport blocks before a grant. A minimum guaranteed transport block size (TBS) may be signaled to permit early generation of a MAC PDU. Transmission parameters may be selected prior to a grant, for example, using blind decoding or a DCI reception procedure.

摘要： A method performed by a STA may comprise receiving a frame, from a first AP including an indication of a configuration change counter (CCC) associated with a second AP. The CCC may be an unsigned integer that increments when an update to one or more AP parameters of the second AP has occurred. The method may further comprise establishing a first wireless link with the first AP and establishing a master key via at least the first wireless link.

摘要： A wireless transmit-receive unit (WTRU) may be provided. The WTRU may be configured to receive a first message from a first relay WTRU. The first message may indicate a service provided by a second WTRU and a first measurement associated with a broadcast message. The WTRU may be configured to determine a second measurement. The second measurement may be associated with the first message received from the first relay WTRU. The WTRU may be configured to send a second message to the first relay WTRU if the first measurement satisfies a first criteria for selecting a relay from a plurality of relays and the second measurement satisfies a second criteria for selecting the relay from the plurality of relays. The second message may comprise an indication to establish communication between the first WTRU and the second WTRU via the first relay WTRU.
