US 7215653 – Claim 34 3GPP Specifications

A mobile station apparatus for 

use in a mobile communications 

system for controlling a data 

transmission rate on a reverse 

link, the apparatus comprising:

receiving means adapted to 

receive a data rate control

command of a base station on a 

forward link common

channel in a dedicated manner, 

the data rate control

command being formed of at 

least one rate control bit

that is signal point mapped to at 

least one symbol of +1,

-1, and 0 to indicate whether the 

mobile station should

increase, decrease, or maintain 

its current data trans

mission rate; and

9.2 Formats and parameters

9.2.5 Signaling of control information for E-DCH

9.2.5.2 DL Scheduling information

This control information is used by Node-Bs in a UE's E-DCH active set in order to 

control its use of E-DCH system resources.

9.2.5.2.1 Relative Grants

- Serving Relative Grant:

Transmitted on downlink on the E-RGCH from all cells in the serving E-DCH RLS, 

the serving relative grant allows the Node B scheduler to incrementally adjust 

the serving grant of UEs under its control. By definition, there can only be one 

serving relative grant command received at any one time. This indication can 

take three different values, "UP", "DOWN" or "HOLD".

4.11 Mapping for E-RGCH Relative Grant

4.11.1 Overview

The relative grant is transmitted on the E-RGCH as described in [2].

4.11.2 Relative Grant mapping

The relative grant (RG) command is mapped to the relative grant value as described 

in the table below.

control means connected with 

the receiving means

transmission rate based on

the data rate control command, 

wherein a bit is sent on

a reverse packet data control 

channel to indicate

whether the mobile station has 

enough power and data

to increase its data transmission 

rate on a reverse packet

data channel.

11.8 Control of E-DCH transmission and reception

11.8.1 UE operation

11.8.1.3 Serving Grant Update

UEs in CELL_DCH state, configured with an E-DCH transport channel shall maintain

a Serving Grant and the list of active HARQ processes based on the absolute and 

relative grant commands decoded on the configured E-AGCH and ERGCH(s).

Each Absolute Grant or Relative Grant command is applied at a specific TTI. This 

association is implicit based on the timing of the E-AGCH and E-RGCH (see [13]). 

The timing is tight enough that this relationship is un-ambiguous.

The activation/deactivation of one or all processes is only applicable to processes 

for which transmission of scheduled data is allowed according to RRC signalling

Process activation of an active process does not result in any action taken by the 

UE.

9.2.5.3.1 Happy Bit

The happy bit is a single bit field that is passed from MAC to the physical layer for 

inclusion on the E-DPCCH. This field takes two values, "Not Happy" and "Happy" 

Case 1:20-cv-22051-JEM Document 1-19 Entered on FLSD Docket 05/15/2020 Page 2 of 4
Page 2 of 3

indicating respectively whether the UE could use more resources or not. The setting 

of the Happy Bit is defined in subclause 11.8.1.5.

11.8.1.5 Happy Bit Setting

The Happy Bit is included on the E-DPCCH for every E-DCH transmission. E-DCH 

transmissions shall not be triggered specifically to allow the transmission of the 

happy bit.

RRC configures MAC with the duration Happy_Bit_Delay_Condition, over which to 

evaluate the current grant relative to the TEBS after application of the E-TFC 

selection procedure described in subclause 11.8.1.4.

For every E-DCH transmission, the Happy Bit shall be set to "unhappy" if the three 

following criteria are met:

1) UE is transmitting as much scheduled data as allowed by the current 

Serving_Grant in E-TFC selection; and

2) UE has enough power available to transmit at higher data rate; and

3) Based on the same power offset as the one selected in E-TFC selection to 

transmit data in the same TTI as the Happy Bit, TEBS would require more than 

Happy_Bit_Delay_Condition ms to be transmited with the current

Serving_Grant × the ratio of active processes to the total number of processes.

The first criteria is always true for a deactivated process and the ratio of the third 

criteria is always 1 for 10ms TTI.

Otherwise, the Happy Bit shall be set to "happy".
