Abstract: Multiple listlets function as a single master linked list to manage data packets across one or more banks of memory in a first-in first-out (FIFO) order, while allowing multiple push and/or pop functions to be performed per cycle. Each listlet can be a linked list that tracks pointers and is stored in a different memory bank. The nodes can include a pointer to a data packet, a pointer to the next node in the listlet and a next listlet identifier that identifies the listlet that contains the next node in the master linked list. The head and tail of each listlet, as well as an identifier each to track the head and tail of the master linked list, can be maintained in cache. The individual listlets are updated accordingly to maintain order of the master linked list as pointers are pushed and popped from the master linked list.

Abstract: This application relates to the field of wireless communications and self-driving/intelligent driving/autonomous driving vehicles, and in particular, to the field of collaborative radars. A first apparatus receives first information from a second apparatus. The first apparatus determines, based on the first information, the priorities of a plurality of time-frequency resources included in a first time-domain range. The first apparatus further selects a first time-frequency resource among the plurality of time-frequency resources. The priority of the first time-frequency resource is the highest among the priorities of the plurality of time-frequency resources. A time-frequency resource with a comparatively high priority is selected to send a radar signal, to reduce a probability of a resource collision, and reduce and/or avoid interference between radars, especially collaborative radars.

Abstract: The present disclosure relates to the mobile communications field, and in particular, to a transmission resource determining technology in a wireless communications system. In a data transmission method, a network device determines a transmission resource used for data transmission, and performs data transmission with a terminal device on the determined transmission resource. A time domain resource occupied by the transmission resource in a time domain is one of N types of time domain resources, and a time length of any type of time domain resource in the N types of time domain resources is less than 1 ms. According to this method, a data transmission latency can be effectively reduced, thereby meeting a requirement for a low-latency service.
