name: DR
full_form: Directed Retry, initial access cell change at call setup
context: The UE shall fulfill the additional requirement specified in Table 7.5C for all values of an adjacent channel interferer up to -25 dBm. However it is not possible to directly measure the ACS, instead the lower and upper range of test parameters are chosen in Table 7.5D and the requirements are given in Table 7.5E and Table 7.5EA for single band 4C-HSDPA and in 7.5F and 7.5G for dual band 4C-HSDPA, where the HS-PDSCH BLER shall not exceed 0.1. The ACS requirement for single band/dual-band 4C-HSDPA is not applicable for dual uplink operation.

description: Directed Retry (DR) is a procedure utilized in the context of cell reselection and initial access cell change at call setup. It is employed in simulations to evaluate the performance of various algorithms, such as CRRM (Combined Resource Reservation and Mobility Management), in managing packet data transmission and improving system capacity.
explanation: The classification of DR as a procedure is based on its usage within the provided context, where it is described as part of simulations evaluating the impact of different algorithms on system performance. The text highlights DR's role in cell reselection and initial access cell change at call setup, indicating its procedural nature.
