Mechanisms of control hold operation and MAC—ID assignment for CDMA2000 1×EV-DV reverse enhanced high-speed packet data channel
First Claim
1. A method comprising:
- initiating a transition by a mobile station from a Control Hold Mode of a reverse link packet data channel for communication between a base station and the mobile station to an active state of the reverse link packet data channel, by sending a transition mode request to the base station;
turning on a rate request channel by the mobile station, the mobile station requesting a reverse link transmission;
monitoring a rate grant channel with the mobile station;
acknowledging the reception of the transition mode request by sending an individual grant to the mobile station from the base station, thereby granting permission to transmit;
transitioning the mobile station to the active state of the reverse link packet data channel upon receipt of the grant, the mobile station starting to transmit on the reverse link packet data channel in autonomous mode; and
,commencing monitoring of a Forward Acknowledgement Channel with the mobile station.

Abstract
Disclosed herein are methods and apparatus for incorporation of a Reverse Link Control Hold Mode and MAC_ID assignment in a cdma2000 1xEV-DV communications system. The teachings herein provide for a reverse link Control Hold Mode for a cellular communications system, wherein a mobile station uses an R-PDCH channel with or without an F-PDCH channel being assigned; alternatively, where a mobile station uses a F-PDCH channel without an R-PDCH channel. A medium access control identification code (MAC_ID) assigned by a base station from a MAC_ID space to each one of a plurality of mobile stations; wherein the MAC_ID is assigned in an ascending (or descending) order from the MAC_ID space for a first group of mobile stations, and wherein the MAC_ID is assigned in a descending (or ascending) order from the MAC_ID space for a second group of mobile stations.
