Methods of efficient bandwidth part switching in carrier aggregation
A method of supporting active bandwidth part (BWP) switching under carrier aggregation (CA) is proposed. To avoid longer switching delay and multiple interruptions in other component carriers (CCs)/cells, the starting time of the later active BWP switching in one cell should fall outside the switching delay of the earlier active BWP switching in another cell. If the later active BWP switching is DCI-based, then the network should schedule the later active BWP switching outside the switching delay of the earlier active BWP switching. If the later active BWP switching is timer-based, then the UE should not perform the later active BWP switching until the earlier active BWP switching is completed. |

Memory arrays comprising strings of memory cells and methods used in forming a memory array comprising strings of memory cells
A method used in forming a memory array comprising strings of memory cells comprises forming a conductor tier comprising conductor material on a substrate. A stack is formed comprising vertically-alternating first tiers and second tiers above the conductor tier. The stack comprises laterally-spaced memory-block regions having horizontally-elongated trenches there-between. Channel-material strings extend through the first tiers and the second tiers. Material of the first tiers is of different composition from that of the second tiers. A lowest of the first tiers is thicker than the first tiers there-above. The first-tier material is isotropically etched selectively relative to the second-tier material to form void-space in the first tiers. Conducting material is deposited into the trenches and into the void-space in the first tiers. The conducting material fills the void-space in the first tiers that are above the lowest first tier. The conducting material less-than-fills the void-space in the lowest first tier. The conducting material is etched from the lowest first tier. After the etching of the conducting material, conductive material is deposited into the void-space of the lowest first tier and that directly electrically couples together the channel material of individual of the channel-material strings and the conductor material of the conductor tier. Additional embodiments, including structure independent of method, are disclosed. |
