A method for a user equipment (UE) operating in a wireless communication system, the method comprising: calculating a first buffer status for a first base station (BS) and a second buffer status for a second BS respectively, by dividing an amount of data available for transmission in a Packet Data Convergence Protocol (PDCP) entity based on a … discounted windows 10 proNettet30. mai 2024 · 3GPP提供了一种有限缓存速率匹配（limited buffer rate matching，LBRM）的机制。在这种机制里，不同的UE终端，其能够使用的最大软缓存比特大小是不同的。继续以FDD制式，20M带 … fours multiplication chart

"NettetYou would see that one bit input become 3 bit output as it goes through the turbo coding processor (It means the coding rate is 1/3). In this process, one input row generate three rows of output as follows. Next step is Rate Matching step. This is the most mesterious part to me. The generic Idea is like this.
