Title:                  1xM2M: NSN proposed stage 3 changes for parallel FL and RL channel
                        acquisition.

Abstract:               1xM2M: NSN proposed stage 3 changes in response to QC C22-
                        20120206-011. Proposal includes a BS control of the feature. The BS
                        control is existing functionality and should be used for this feature.

Recommendation:         Review and adopt.
Introduction:
This contribution proposes the use of an existing “EARLY_RL_TRANSMIT_INDs” flag to be used for the
parallel FL and RL channel acquisition.

EARLY_RL_TRANSMIT_INDs – The early reverse link transmission flag indicates whether, upon channel
assignment, the mobile station is allowed to enable its transmitter and transmit the preamble prior to receiving
sufficient energy on the forward link.

2.6.4.2 Traffic Channel Initialization Substate

[…]
If all of the following conditions are true:

         F-CPCCH is not assigned, and
         EARLY_RL_TRANSMIT_INDs equals ‘1’ or the mobiles station is capable of early reverse
          link transmission,
the mobile station shall perform the following:

         The mobile station shall adjust its transmit power as specified in [2].
         The mobile station shall transmit the Traffic Channel preamble as specified in [2], and
          Layer 3 shall send an acquiring dedicated channel indication to Layer 2 (see [4]).

         If CH_INDs equals ‘00’, the mobile station shall commence R-CQICH reporting as
          specified in [2].
         If the mobile station receives a period of (N5m x 20) ms with sufficient signal quality on
          the physical channel corresponding to FPC_PRI_CHANs within T79m seconds after
          entering this substate, the mobile station shall perform the following additional
          functions while it remains in the Traffic Channel Initialization Substate:

          -   The mobile station shall perform Forward Traffic Channel supervision as specified in
              2.6.4.1.8. If a loss of the Forward Traffic Channel is declared, the mobile station
              shall enter the System Determination Substate of the Mobile Station Initialization
              State with a system lost indication (see 2.6.1.1).

          -   The mobile station shall process Forward Traffic Channel signaling traffic and shall
              discard other types of Forward Traffic Channel traffic.
         If the mobile station does not receive a period of (N5m x 20) ms with sufficient signal
          quality on the physical channel corresponding to FPC_PRI_CHANs within T79m seconds
          after entering this substate, the mobile station shall perform the following:
          -   The mobile station shall disable its transmitter.

          -   The mobile station shall discard any messages queued for transmission, and those
              messages received and pending processing.

          -   The mobile station shall remain in this substate and perform the procedures below.

If all of the following conditions are true:

         F-CPCCH is not assigned, and
         EARLY_RL_TRANSMIT_INDs equals ‘0’, or EARLY_RL_TRANSMIT_INDs equals ‘1’ and
          the T79m timer has expired,
