Abstract:
Embodiments of apparatus and methods for signaling for resource allocation and scheduling in 5G-NR integrated access and backhaul are generally described herein. In some embodiments, User Equipment configured for reporting a channel quality indicator (CQI) index in a channel state information (CSI) reference resource assumes a physical resource block (PRB) bundling size of two PRBs to derive the CQI index.
Abstract:
Some demonstrative embodiments include devices, systems and/or methods of Time-Division Duplexing (TDD) Uplink-Downlink (UL-DL) interference management. Some embodiments include transmitting a message including a channel quality parameter and a Time-Division-Duplex (TDD) configuration update to at least one other base station of a cellular cell, deciding if the cellular cell is to be operated in a cluster based on the channel quality parameter value, and coordinating an adjustment of uplink-downlink configuration according to a traffic condition.
Abstract:
Technology for adapting uplink-downlink (UL-DL) time-division duplexing (TDD) subframe configurations in a heterogeneous network (HetNet) is disclosed. One method can include a reference enhanced Node B (eNB) determining a preferred adaptive UL-DL configuration. The eNB can receive node configuration information for at least one neighboring node. The eNB can reconfigure an adaptive UL-DL configuration for at least one of the reference eNB and the at least one neighboring node based on the node configuration information and sounding reference signal (SRS) subframe scheduling of the reference eNB and the at least one neighboring eNB.
Abstract:
Devices and systems of sensing, resource selection and control signaling for feedback-less and feedback-based NR-V2X sidelink communication are described. Resource reservation and selection for sidelink retransmissions based on HARQ feedback are described for unicast, groupcast, and broadcast blind retransmissions. After exchanging HARQ feedback capability information for different types of communications, a HARQ-dependent or HARQ-independent resource selection occurs. Look-ahead and/or chain-based resource selection and reservation signaling is used, in which a single resource or some or all of the resources selected are signaled as reserved. Further resource selection of a single additional resource may occur after an initial resource selection. The resource selection for retransmissions may be adapted using a RSRP or distance threshold.

Abstract:
Technology for traffic offloading to generate a low interference flexible subframe (FlexSF) of an adaptive uplink-downlink (UL-DL) time-division duplexing (TDD) subframe configuration in a heterogeneous network (HetNet) is disclosed. One method can include an evolved Node B (eNB) monitoring a traffic loading metric for a specified traffic loading condition. The eNB can offload traffic scheduled for a packet of a macro user equipment (UE) from a macro cell to a FlexSF of a UL-DL subframe configuration of a small cell when the specified traffic loading condition exists. The eNB can be a macro eNB of the macro cell or a small eNB of the small cell.
Abstract:
A base station transmits to a number of relay stations in a wireless network using a beamforming matrix. The beamforming matrix is generated by first obtaining a column vector from a beamforming matrix associated with each of the relay stations. An intermediate matrix is then generated using these column vectors. A zero-forcing procedure is then utilized to process the intermediate network to generate the final beamforming matrix.
Abstract:
An apparatus and system of enabling reference signal measurements in a non-terrestrial network (NTN) system are described. The UE provides capability information that indicates a maximum number of synchronization signal block (SSB)-based measurement timing configurations (SMTCs) simultaneously supported by the UE for measurement of reference signals from cells in the NTN system and receives SMTCs based on the capability information and a real time estimate of timing differences among the cells. The UE sends/receives data based on the SMTCs and whether the UE supports simultaneous data communication and measurement. Broadcast system information contains a flag that indicates which of dynamic and semi-static configuration is used, the maximum SMTC's dependent on the flag value. Radio resource control (RRC) signalling is used to send sets of SMTCs that have different offsets. Different sets are activated using dynamic signaling according to real time estimates of the timing differences.
Abstract:
Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The UE receive training signals from a plurality of transmit-receive points (TRPs) associated with the gNB. Each training signal may comprise a reference signal resource identifier (ID) to indicate a corresponding TRP and a corresponding transmit direction of a plurality of transmit directions. The UE may, for each transmit direction of the plurality of transmit directions, determine an average signal quality measurement based on individual signal quality measurements in multiple receive directions. The UE may select, for reporting to the gNB, a subset of the average signal quality measurements to ensure that the average signal quality measurements excluded from the subset are less than or equal to a minimum value of the average signal quality measurements in the subset.
