Power Consumption and Latency in IEEE 802.11ax State Transitions

This document discusses power consumption and latency values in state transitions for IEEE 802.11ax simulation scenarios. It covers power states definition, common power model parameters, and state transitions within the simulation scenarios. The transitions include Transmit to Listen, Receive to Listen, Receive to Shallow Sleep, Listen to Shallow Sleep, Listen to Deep Sleep, and more.

1. May 2015 doc.: IEEE 802.11-15/0576r2 Power Consumption and Latency Values in State Transitions for IEEE 802.11ax Simulation Scenarios Date: 2015-05-13 Authors: Name Affiliations Address Phone email +1-415-244-8904 chittabrata.ghosh@intel.com Chittabrata Ghosh 2200 Mission College Blvd., Santa Clara, CA Intel chen.kojokaro@intel.com Chen Kojokaro Submission Slide 1 Chittabrata Ghosh, Intel

2. May 2015 doc.: IEEE 802.11-15/0576r2 Abstract The Simulation Scenarios document [1] has mentioned about modeling power consumption in various state transitions of three considered power save mechanisms Two sleep states have been introduced in [2] namely, shallow sleep and deep sleep In this contribution, we discuss the latency and power consumption values for every possible state transition Transmit to Listen and vice versa Receive to Listen and vice versa Receive to Shallow Sleep Listen to Shallow Sleep and vice versa Listen to Deep Sleep and vice versa Submission Slide 2 Chittabrata Ghosh, Intel

3. May 2015 doc.: IEEE 802.11-15/0576r2 Various Power States Definition Simulation Scenarios document [1] of IEEE 802.11ax specifies the following common power model parameters for all simulation scenarios Sleep power state is defined as the state when the STA is in Doze state and receiver is off Power State Average Current Consumption [mA] Transmit [mA] 280 Receive [mA] 100 Listen [mA] 50 Shallow Sleep [mA] 0.9 Deep Sleep [mA] 0.003 Deep Sleep [2] power state is defined as a sleep state with the least (non-zero) power consumed and the longest transition time to Listen state. Shallow Sleep [2] power state is defined as a sleep state when the STA consumes more power but transitions faster to Listen state when compared to the Deep Sleep power state Submission Slide 3 Chittabrata Ghosh, Intel

6. May 2015 doc.: IEEE 802.11-15/0576r2 Power and Latency Transitions Between States in IEEE 802.11ax We propose to replace the existing Table under Common Power Model Parameters for all simulation Scenarios in Simulation Scenarios document doc. IEEE 802.11-14/0980r6 [1] with the Table below Power Consumption and Latency Values in State Transitions State Transitions Transition Time (ms) Power Consumption (mW) Transmit Listen TTL = 0.010ms 75mW Receive Listen 0.001ms 55mW Receive Listen Transmit TRT TLT = 0.010ms PRT PLT = 100mW Transmit Shallow Sleep TTS = 0.01ms PTS = 15mW Receive Shallow Sleep TRS = 0.2ms PRS = 15mW Listen Shallow Sleep TLS = 0.2ms TSL = 0.5ms TLD = 0.01ms TSDL= 3ms PLS = 5mW Shallow Sleep Listen Listen Deep Sleep PDS = 5mW Deep Sleep Listen Submission Slide 6 Chittabrata Ghosh, Intel
