Express signaling in a wireless communication system
First Claim
1. A method for transmitting a plurality of control and signaling information between a base station and one or more mobile stations in a wireless communication network, the method comprising:
- modifying one or more prescribed fields in an existing media access control (MAC) channel to carry a plurality of control and signaling information directly between the base station and at least one mobile station by performing a cyclic redundancy check (CRC) calculation over the contents of a control field and mobile station identifier, wherein the control and signaling information includes one or more identifiers, and wherein one or more of the identifiers includes a message type.

Abstract
A method for transmitting control information in a wireless communication network is provided in which one or more prescribed fields in an existing control channel structure are modified to enable express signaling directly between a base station and at least one mobile station without the need to traverse a backhaul path between the base station and the base station controller. More specifically, prescribed fields in the control channel are modified to carry one or more prescribed message identifiers that convey different types of information, e.g., an identifier for indicating which mobile station is the intended recipient, an identifier for indicating the type of message being transmitted (e.g., broadcast, multicast, etc.), a message identifier indicating the available Walsh space for data transmission, and so on. In this manner, existing control channel structures and formats can accommodate many different signaling functions directed to either single or multiple mobile stations.

19. A method for transmitting a plurality of control and signaling information between a base station and one or more mobile stations in a wireless communication network, the method comprising:
-
modifying one or more prescribed fields in an existing media access control (MAC) channel to carry one or more prescribed message identifiers between the base station and the one or more mobile stations by performing a cyclic redundancy check (CRC) calculation over the contents of a control field and mobile station identifier, wherein the one or more prescribed message identifiers comprise control and signaling information selected from the group consisting of routing information, message type, control information, and a signaling message, whereby express signaling occurs directly between the base station and at least one mobile station.
