Abstract: A base station may generate first configuration information to configure a first user equipment (“UE”) to operate using a first bandwidth within a wideband carrier of a cell, generate second configuration information to configure a second UE to operate using a second bandwidth within the wideband carrier of the cell, and cause transmission of the first and second configuration information to the first and second UEs, respectively. The base station may configure the first and second UEs based upon capabilities received from each UE, respectively.

Abstract: Techniques discussed herein can facilitate multi-transmission reception point (multi-TRP) operation for new radio (NR). One example apparatus may be employed at a user equipment (UE) and may comprise one or more processors configured to transmit uplink control information (UCI) on two physical uplink control channels (PUCCHs). The two PUCCHs occupy different symbols in the same slot.

Abstract: Techniques for observed time difference of arrival (OTDOA) positioning based on heterogeneous reference signals (RSs) are discussed. One example apparatus configured to be employed within a user equipment (UE) comprises receiver circuitry, a processor, and transmitter circuitry. The receiver circuitry can receive, from each of a plurality of evolved Node Bs (eNBs), one or more RSs of each of a plurality of distinct types of RSs. The processor can determine, for each of the eNBs, a time of arrival (TOA) of the one or more RSs of each of the plurality of distinct types of RSs; and compute, for each of the eNBs, a reference signal time difference (RSTD) based at least in part on the TOAs of the one or more RSs of each of the plurality of distinct types of RSs. The transmitter circuitry can transmit the RSTD computed for each of the eNBs.

Abstract: Technology for an apparatus of a user equipment (UE), operable to perform a random-access procedure using a UE-specific control resource set (CORESET) is disclosed. The UE can decode a 5 message, received from the next generation node B (gNB), to perform a contention free random-access (RA) procedure. The UE can encode a random-access channel (RACH) preamble for transmission to the gNB using one or more UE-specific CORESET. The UE can decode a random-access response (RAR) received from the gNB in response to the RACH preamble transmission using the one or more UE10 specific CORESET.

Abstract: Embodiments of a Generation Node-B (gNB), User Equipment (UE) and methods for communication are generally described herein. The gNB may map data symbols to resource elements (REs) of virtual resource blocks (VRBs). The gNB may interleave the data symbols, on a per-VRB basis, to spatial layers of a multi-layer multiple-input multiple-output (MIMO) transmission. The data symbols may be interleaved based on different interleave patterns of VRB indexes for the spatial layers. The gNB may map the interleaved data symbols of the spatial layers to REs of physical resource blocks (PRBs) for orthogonal frequency division multiplexing (OFDM) transmission.

Abstract: Embodiments of a User Equipment (UE), a generation Node-B (gNB) and methods for communication are generally described herein. The UE may the UE 102 may receive from a gNB, control signaling that indicates: a first pre-coding matrix indicator (PMI) that indicates a first pre-coder for a first sub-band; and a second PMI that indicates a second pre-coder for a second sub-band. The first and second pre-coders may be included in predetermined candidate pre-coders. The UE may encode a physical uplink shared channel (PUSCH) block for transmission. The UE may scale the PUSCH block in the first sub-band by the first pre-coder. The UE may scale the PUSCH block in the second sub-band by the second pre-coder.

Abstract: A receiver processes a data signal and provides an acknowledgement within a turnaround time through use of code block alignment, reduced complexity or increased processing time. In a first embodiment, a radio access network (RAN) node enables encoded information to be segmented into multiple code blocks and maps a group of code blocks to be aligned with orthogonal frequency division multiplexing (OFDM) symbol boundaries such that efficient receiver processing can implement processing pipelining. In a second embodiment, the transmitter can provide more time or reduce the complexity of the packet, such as by repetition of bits of code blocks of the encoded information or by reserving resource elements (REs) such that the receiver has effectively more time (or less complexity) to process the last or last few code blocks of the packet.

Abstract: Technology for a Next Generation NodeB (gNB) operable to encode downlink control information (DCI) for transmission to a user equipment (UE) is disclosed. The gNB can identify DCI for transmission from the gNB. The gNB can determine that a size of the DCI exceeds a defined threshold. The gNB can divide the DCI into one or more DCI segments. Each DCI segment can include header information to enable the one or more DCI segments to be assembled at the UE. The gNB can encode the one or more DCI segments of the DCI for transmission from the gNB to the UE.

Abstract: Described are mechanisms for eNB support of DRS in LAA, in which DRS is transmitted at one or more DRS occasions within a DMTC window, subject to LBT. In some embodiments, an eNB may include hardware processing circuitry comprising an antenna port, a first circuitry, a second circuitry, and a third circuitry. The first circuitry may be operable to determine a DMTC window of a wireless communication channel. The second circuitry may be operable to initiate one or more CCA checks through an antenna coupled to the antenna port prior to a DRS occasion within a DMTC time window. The third circuitry may be operable to initiate a DRS transmission through the antenna within the DMTC window upon a CCA check of the set of one or more CCA checks sensing that the wireless communication channel is idle. Also described are mechanisms for proactive support of DRS in LAA.
