Abstract: First resource elements (REs) are configured for determination of different components of interference that affects communications between a first user equipment (UE) and a first network device in a wireless communication system. The first REs include REs that correspond to a subset of REs in a set of second REs, and the set of second REs includes all REs at a time position in a time-frequency grid that are muted for communications by a second UE. The first REs further include an RE that corresponds to an RE at a time position in the time-frequency grid, different from the time position of the REs that are muted. The interference may include cross-link interference between links in the same wireless communication system, or links in different wireless communication systems such as a terrestrial network and a non-terrestrial network.

Abstract: Embodiments disclosed herein encompass methods, apparatus, and systems for interference management. First resource elements (REs) are configured to enable measurement of interference that affects communications between a first user equipment (UE) and a first network device in a wireless communication system. The first REs include REs that correspond to a subset of REs in a set of second REs, and the set of second REs includes all REs at a time position in a time-frequency grid that are muted for communications by a second UE. Interference mitigation based on the interference measurement may be applied to manage the interference. The interference may include cross-link interference between links in the same wireless communication system, or links in different wireless communication systems such as a terrestrial network and a non-terrestrial network.

Abstract: Aspects of the present disclosure provide a manner of associating a physical layer channel, such as, but not limited to, physical broadcast channel (PBCH), physical downlink control channel (PDCCH), and physical uplink control channel (PUCCH) and a receive beam assumption. The beam assumption may, for example, relate a receive beam direction with a reference signal transmitted by a base station in which the reference signal is used for any of multiple uses by a user equipment (UE), such as beam management, multiple BS, including terrestrial BS and/or non-terrestrial BS, and UE mobility.

Abstract: In an integrated wireless communication network that includes terrestrial and non-terrestrial network devices, signaling that is indicative of information for application by a User Equipment (UE) in selection between multiple cooperation nodes to provide the UE with access to a non-terrestrial network device in the integrated wireless communication network is communicated. Cooperation may also or instead be applied in conjunction with a group handover procedure. For example, signaling that is indicative of information for application in making a handover determination by a cooperation node may be communicated.

Abstract: After carrying out, for a first duration, a first beam activity cycle monitoring for at least one physical downlink control channel (PDCCH) message on a first link using a first QCL assumption type, a user equipment (UE) may perform a QCL switching operation to a second beam activity cycle monitoring for at least one PDCCH message on a second link using a second QCL assumption type. The beam activity cycle durations may be represented in information elements referenced in a TCI/QCL framework, with additional fields. Similarly, the beam activity cycle QCL assumption types may also be represented in information elements referenced in the TCI/QCL framework.

Abstract: A first user equipment (UE) is configured to receive from a base station a signaling comprising indication of one or more time-frequency resources and an indicator indicating a time gap, and transmit a transport block (TB) to a second UE using the one or more time-frequency resources. For each of the time-frequency resources, the first UE monitors a hybrid automatic repeat request (HARQ) feedback from the second UE, using a physical sidelink feedback channel (PSFCH) resource; and transmits to the base station a HARQ feedback report signal based on the HARQ feedback or absence thereof, in a physical uplink control channel (PUCCH), using a single PUCCH resource determined based on the time gap from a last one of the PSFCH resources.

Abstract: According to implementations, a UE may obtain measurements for signals received over different elevation angles. Subsequent to obtaining the measurements, the UE may transmit a feedback report including at least one of indications of the measurements, indications of UE capabilities as well as indications regarding constraints on beam directions. Upon receipt of feedback reports from a plurality of UEs, a network node may configure a UE-centric BTC for each UE in the plurality of UEs and then transmit UE-centric BTC configuration information to each UE for communicating at least one of physical signals and physical channels.

Abstract: In some wireless communication scenarios, a situation may arise in which the propagation delay between the user equipment (UE) and the transmit-and-receive point (TRP) is such that by the time a grant is received by the UE and data is transmitted by the UE according to the grant, the channel conditions have changed. In some embodiments, the UE instead autonomously selects at least one resource for a grant-based data transmission. For example, the UE may select the resource based on channel conditions locally measured by the UE. A method may include a UE receiving a flag and a grant scheduling at least a time resource for data. The flag indicates that the UE is to transmit the data using at least one resource selected by the UE. The UE transmits the data on the time resource using the at least one resource selected by the UE.

For example, signaling that is indicative of information for application in making a handover determination by a cooperation node may be communicated.

Abstract: A hierarchical beam-deployment method has the step of transmitting signal beams of multiple levels towards a service area, each signal beam comprising a synchronization signal and physical broadcast channel block (SSB); the footprint of a higher-level beam has a beam-width smaller than that of a lower-level beam, and is at least partially overlapping with the footprint of the lower-level beam. Accordingly, a beam-search method has the steps of detecting a first SSB of a first signal beam; determining, based on the first SSB, a presence of one or more second signal beams having one or more footprints at least partially overlapping with a footprint of the first signal beam; detecting one or more second SSBs of the one or more second signal beams; and selecting at least one of the first and second SSBs for performing an initial-access procedure based on the selected SSB.

Abstract: A communication system, a radio access network (RAN), a user equipment (UE), and/or one or more non-transitory computer-readable storage devices are configured for performing a method leveraging a highly overlapping beam layout for communication between the RAN and UE. The method may include: receiving a plurality of synchronization signal blocks (SSBs) of a plurality of beams of a plurality of different beam layers, each SSB associated with a respective beam, and each beam associated with a respective beam layer; determining reference-signal received powers (RSRPs) of the SSBs; and selecting one or more of the SSBs based on the measured RSRPs for performing an initial-access procedure to a serving cell. Based on the received position information, the RAN may transmit a narrow-width beam towards the UE for performing an initial-access procedure to a serving cell.

Abstract: Embodiments of the present invention provide a reference signal notification method, including: sending, by a network device, a reference signal notification message, where the reference signal notification message includes time resource information of a reference signal. According to the embodiments of the present invention, the reference signal notification message in the present invention is used to notify UE of a reference signal configuration, especially information about a CSI-RS, so that the network device can flexibly provide a reference signal, especially a CSI-RS, and the UE can more effectively receive the reference signal, especially the CSI-RS.

Abstract: Aspects of the present application relate to removing the separateness and independence of positioning practices implemented for terrestrial networks and the positioning practices implemented for non-terrestrial networks. In part, a new framework of user equipment (UE) machine states is introduced. Each of the UE power modes may be associated with specific functions. A UE and a transmit receive point (TRP) may engage in handshaking that includes the UE transmitting a request to change from a first UE power mode to a second UE power mode. Responsive to the request, the UE may receive, from the TRP, a response. The response may include information to allow the UE to perform one or more functions associated with the second UE power mode. Among the UE power modes may be a low power mode, wherein the UE carries out functions limited to little more than positioning.

Abstract: The present disclosure relates to data block retransmission in wireless communications, and particularly in wireless communications having a relatively large propagation delay. Some embodiments relate to memory management and may involve a maximum time period during which a data block that is to be communicated in a wireless communication network may remain in memory space at a user equipment (UE) to support a data block retransmission procedure. UE reporting of current occupancy status of the memory space is also or instead supported in some embodiments. Selective transmission or retransmission may be provided, and may involve reception occasions at which a UE may receive a data block retransmission or a transmission of a different data block.

Abstract: A method for uplink transmission by a UE includes obtaining information regarding a plurality of power control sets each having a plurality of power control parameters, wherein a value of at least one parameter in a first power control set is different from a value of the at least one parameter in a second power control set; obtaining information associating at least one of the power control sets with at least one operational property of the UE; and when at least one of the operational properties is in effect on the UE, transmitting a PUSCH using the parameters of the power control set associated with the at least one operational property in effect.

Abstract: Embodiments of this disclosure improve the reliability of blind decoding when beamforming is used by having a user equipment (UE) receive a single downlink control information (DCI) message with different transmission and/or reception parameters. In some embodiments, a UE receives more than one set of configuration parameters, where any two sets of configuration parameters out of the more than one set of configuration parameters have at least one different parameter. The UE may receive two sets of configuration parameters each having a different transmission modes, but the same search space type. Additional examples are also provided.

Abstract: Aspects of the present disclosure provide an enhanced procedure for wireless network access and, in particular examples, a location-aware access procedure in which the location of an apparatus is used to streamline the access procedure for enabling the apparatus to access the network. The location of the apparatus may be used to inform transmission of a synchronization message to the apparatus. The apparatus may transmit a request to access a network based on its location relative to another apparatus in the network. Using the location of the apparatus can reduce network overhead and latency, whilst saving power at the apparatus.
