`
`Purposes of Reverse Link Data Rate Control
`
` To provide performance enhancements and symmetric operation
`with forward link
`– Effective bandwidth allocation is required
` Based on grade of service or mobile station
`– Overshoot is not desirable
` Fluctuation depth should be small
`– Full reverse link utilization is guaranteed
` Based on the cell environment, quick saturation or conversion to
`maximum capacity should be achieved
` All Performance enhancements should be provided without
`overhead or with minimum overhead

`
`Existing control schemes for Reverse Link (1)
`
` Common control schemes for Reverse Link Data Rate
`– Common information from the BS is sent to all MS in the cell
`– A small amount of overhead is required, but dynamic and efficient
`reverse link data rate control can not be provided
`– 1xEV-DO Reverse MAC operation
` 1 bit RAB(Up and Down Reverse Activity Bit) through Forward common
`control channel
` 1 bit per cell (common information for all mobile stations)
` PV(Persistence Value) test
` To increase or decrease the data rate, the MS performs the persistent test
`based on the probability predefined from the BS and decides the data rate
`to be increased or decreased
` Dynamic and individual data rate control for each MSs are not provided
` But, just 1 bit and PV are required to control RL- data rate

`– Designated information from the BS is sent to each MS in the cell
`– A large amount of overhead is required, but dynamic and efficient

`– LGE and Airvana’s proposals for 1xEV-DV
` 2 bits RAB(Up, Down and Keep) through Forward dedicated control
`channel
` 2 * N bits per cell(where, N is the number of active mobiles in the cell)
` Designated information for each mobile stations

`
`Proposed Data Rate Control of Reverse Link (1)
`
` IAB(Increase Availability Bit) is proposed to provide effective
`reverse link data rate control
`– 1 bit indicator(IAB) to notify the status of the Mobile station
`– The MSs in the cell send an IAB, which is set to ‘0’, to the Base
`station to request it’s reverse link data rate up
`– A concept of IAB can be applicable for both common and dedicated
`control scheme for reverse link data rate
` And also, a concept of RAB proposed in common and dedicated
`control scheme is preserved
`– Only 1 bit IAB bit is added on the reverse link regardless of reverse
`link data rate control scheme(common or dedicated)
` The functionalities defined in 1xEV-DO are also preserved
`– Persistence Value and RRL(Reverse Rate Limit) message
` MARDC(Mobile Assistant Reverse link Data rate Control)

`
`Proposed Data Rate Control of Reverse Link (2)
`
` Operation of Mobile Station
`– The MS sends an IAB through the reverse link to the BS
` IAB is set to ‘0’ : Rate Increase Enabled
` IAB is set to ‘1’ : Rate Increase Disabled
`– The MS may(will) set an IAB to ‘1’ when the MS can not(or does
`not want to) increase its data rate
` Current data rate is the same as data rate limited by RRL message
` Data rate is limited due to MS’s transmission power
` The MS has a small amount of data to be sent in Tx buffer
` Less than threshold of Tx Buffer
` At least one RAB is set to “Down” when MS is being controlled by two
`or more base stations
`– The MS may(will) set an IAB to ‘0’ when the MS wants to increase
`its data rate due to buffer overflow, or etc.

`
`Proposed Data Rate Control of Reverse Link (3)
`
` Operation of Base Station
`– Receiving upon the IABs from the MSs, the BS decides that which
`MS wants to increase its data rate or not
`– The BS knows its remaining reverse link capacity and the number
`of MS which sent the IAB set to ‘0’
` The BS can dynamically and efficiently control the reverse link full
`capacity and utilization using the IAB from the MSs
` The BS can selectively allow the increasing of the reverse link data rate
`based on a demand from the specific MS, but the reverse link stability
`can be maintained without any interferences

`
`Simulation Environments and Assumptions (2)
` Traffic source : burst generation
`– Inter-burst time : exponential distribution (mean : 240 ms)
`– Packet size : fixed (9.6kbps X 20ms = 192 bits)
`– Number of packets per each burst : geometrical distribution with
`mean 62.5 packets (= 1500 bytes)
` Reverse link frame size : 20ms
` Reverse link threshold (or target data rate ) : 1228.8 kbps
` Effective data rate in common control scheme
`– Overshoots over the target data rate are considered as throughput
`decrease in reverse link(or data rate)
`– 2 times of a portion of the overshoot is assumed to be an amount
`of reduction of the reverse link data rate

`Conclusions
`
` The proposed IAB operation requires a Minimum overhead
`– Additional 1 bit(IAB) may be required on the reverse link
` The proposed IAB can be adopted for both common control and
`dedicated control of reverse link data rate
` The proposed IAB operation can provide higher aggregate
`(effective)data rate of the reverse link in both common and dedicated
`control scheme
` The proposed IAB operation provides that the BS can estimate an
`amount of increasing data rate and self interference because the BS
`knows the reverse link remaining capacity and the number of MS which
`can increase its data rate
`– The reverse link capacity can be utilized
`– Fully dynamic data rate control and allocation can be provided
`– Reverse link load balancing can be achieved
`– The MS’s Tx buffer control can be provided
