Spreadtrum · 10.4

Spreadtrum proposes studying whether the BS LP/EE mode is an isolated state versus a mode performed during a sleep state with additional relative power value. They require reusing UE/Group paging rates from TR 38.869 and require companies to report specific values for N and RE,REF. They propose the additional energy overhead for 2Rx scales by 1.4 times that of 1Rx (yielding a value of 21) and propose specific power values for 10MHz BW with 1Rx (12 for micro sleep, 14 for light sleep, 18 for deep/ultra-deep). They oppose introducing PDSCH-only and BB-only active power states, arguing PDSCH-only power can be scaled from PDCCH+PDSCH value and BB-only relaxation is already captured by DL bandwidth adaptation rules. They propose reusing the agreed PDCCH-only bandwidth scaling rule for other DL signals/channels such as SSB, CSI-RS, and PRS, and oppose introducing new scaling rules for BD complexity or PDCCH symbol number for PDCCH-only slots, preferring to reuse the TR 38.875 scaling rule.

Spreadtrum proposes to reduce 6G UE power model complexity by removing bandwidth configurations (5%, 400MHz) from the UE power model and eliminating the maximum schedulable PDSCH throughput ratio parameter from PDCCH-only state. They argue that 400MHz support is undetermined and potentially requires CA, making it unnecessary for evaluation. They oppose introducing a baseband-only PDSCH processing state and related scaling rule, arguing bandwidth adaptation rules already reflect PDSCH processing relaxation. For micro-sleep, they propose a simple two-point scaling rule reusing the legacy 45 power units for 100MHz and defining a single X power unit for 200MHz, explicitly rejecting a more complex scaling approach. They further require that ultra deep sleep state be confined exclusively to IoT devices, not applicable to eMBB devices.
