SpletPDCCH LINK ADAPTATION tuning Summary • In the attempt to improve the performance (throughput) some parameters controlling the use of the PDCCH resources were tuned. • … SpletSince the radio conditions for the different radio links within a cell typically vary independently, at each point in time there is almost always a radio link whose channel quality is near its peak and supporting a correspondingly high data rate. This translates into a high system capacity.
SpletThe PDCCH DCI formats 1, 2, 2A, and 2B with type 0, and PDCCH DCI formats 1, 2, 2A, and 2B with type 1 resource allocation have the same format and are distinguished from each … SpletSmaller the PDCCH capacity, the more relative gain we get from joint packet bundling and LA. With 6 control channels the capacity gain with LA and packet bundling is 106%, with 8 control channels ...
SpletEnhanced PDCCH link adaptation feature was introduced in L13B. The L13B solution allows efficient use of the PDCCH resource by having a better outer loop algorithm. The channel quality measurements reported to the RBS by each user are subject to measurements errors, reporting delays and channel fluctuations. SpletENHANCED PDCCH LINK ADAPTATION In legacy functionality, the PDCCH outer loop was really the outer loop for PDSCH plus fixed 10 dB margin. Since PDCCH and PDSCH …
SpletThe number of consecutive CCEs required to carry one PDCCH is called "Aggregation Level'. TS 36.211 Table 6.8.1.1 shows these relations. Now let's look into a little bit deeper and see how 'Number of PDCCH bits' is derived for each PDCCH. Number of PDCCH bits for PDCCH Format 0 = 1 (CCE) x 9 (REG/CCE) x 4 (RE/REG) x 2 (bits/RE, QPSK) = 72.
SpletFor PDCCH, link adaptation is used where a PDCCH can consist of 1, 2, 4, or 8 control channel elements (CCEs). By selecting the number of CCEs (referred to as the … nervous impulses in the respiratory systemSpletdownlink control channel (PDCCH) is a core element to enable all physical layer data transmissions.
