摘要： Systems, devices, and techniques for wideband operations in unlicensed spectrum are described. A described technique receiving, by a user equipment (UE), a schedule for transmitting on a Physical uplink shared channel (PUSCH) over at least a portion of a plurality of listen-before-talk (LBT) subbands of a bandwidth part (BWP) in an unlicensed spectrum. The scheduled PUSCH bandwidth indicated by the schedule can be greater than a unit bandwidth of a LBT subband. The technique includes performing, by the UE, a LBT procedure on each scheduled LBT subband of the plurality of LBT subbands, each of the scheduled LBT subbands being associated with the scheduled PUSCH bandwidth. The technique includes performing, by the UE, a PUSCH transmission in accordance with the schedule that uses one or more of the scheduled LBT subbands that have passed the LBT procedure.

摘要： Systems and methods for determining channel raster(s) and synchronization signal raster(s) for New Radio (NR) unlicensed spectrum are disclosed herein. For each of a plurality of data objects an NR channel raster position is determined using Absolute Radio Frequency Channel Number (NR-ARFCN) numbers. For each corresponding NR channel, Global Synchronization Channel Numbers (GSCNs), a number of Physical Resource Blocks (PRBs) based on channel subcarrier spacing (SCS), NR channel raster position placement, channel edges, synchronization signal and physical broadcast channel (SSB) edges, and an SSB raster position are calculated. The plurality of data objects may then be down selected based on e.g., corresponding Long Term Evolution (LTE) channel raster positions and/or entries of a second plurality of data objects calculated for NR channels that use a second SCS.

摘要： Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for determining dynamic power sharing in a dual-uplink E-UTRA (Evolved Universal Terrestrial Radio Access)—new radio dual connectivity (EN-DC) network, and/or other new radio (NR) related networks. Various embodiments describe how to determine or configure respective transmission (TX) power levels for LTE and NR uplink signals in the dual-uplink EN-DC network. The NR uplink signal may or may not be transmitted based on a certain timeline threshold and/or power scaling threshold. Other embodiments may be described and claimed.
