Abstract: Introduced here are insertion schemes in which queues can be branched into one or more sub-queues for more effective management of queuing elements. Often, a computing device will have a primary buffer into which queuing elements are populated for execution by a processor. However, the amount of contiguous memory space allocated for the primary buffer may be fixed. To address this, a queue manager may insert indicators that link to secondary buffers into the primary buffer in order to expand the number of effective entries in the primary buffer.

Abstract: An apparatus and method for downlink data transmission and decoding are disclosed. In the method, a physical layer code block or a physical layer code block group is decoded. A medium access control (MAC) sub-packet corresponding to the decoded physical layer code block or the physical code block group is decoded without waiting for any subsequent physical layer code blocks to be decoded. The decoded MAC sub-packet is passed up a protocol stack.

Abstract: The present disclosure provides an electrical connector. The electrical connector includes an insulating body and one or more reinforcing members. The insulating body comprises a pair of side portions which extend in a longitudinal direction, and a pair of tower portions which are connected to respective ends of the pair of side portions. The pair of side portions and the pair of tower portions form a longitudinal card slot. The ends of the card slot extend into the pair of tower portions respectively. A reinforcing member may be arranged in a tower portion. When an electronic card is inserted into the card slot, the one or more reinforcing members can maintain the shape of the tower portions and prevent deformation or cracking of the tower portions when the electronic card is impacted by an external force.
