Method and control channel for uplink signaling in a communication system
First Claim
1. A method of transmitting control signals in a communication network, comprising:
- transmitting only control signal data related to scheduling for uplink transmission of packet data over a single control channel, the single control channel having physical structure and data arrangement therein corresponding to the control signal data transmitted on the single control channel, the physical structure of the control channel and the data arrangement in the control channel being selected based on a user transmission mode, the transmitting of the control signal data includes one of,transmitting one or more of medium access control buffer status data, transport format data, transport block size data and redundancy data, if the transmission mode is a scheduled transmission mode,transmitting one or more of, transport format data, transport block size data, HARQ channel ID data and an indicator indicating whether data carried on a corresponding data channel is a new packet or a re-transmission of a previous packet, if the transmission mode is a rate-controlled transmission mode, andtransmitting one or more of medium access control (MAC) buffer status data, pilot transmit power data and data related to priority of a packet in the MAC buffer, if a user is configured in a reporting mode.

Abstract
In a method of transmitting control signals for uplink transmission of packet data in a communication network, control signal data related to scheduling a user for uplink transmission of packet data is transmitted over a single control channel. The single control channel may be configured based on the transmission mode the user is in for scheduling an uplink transmission from the user to the network, so that only one control channel is used, regardless of the transmission mode the user is in for scheduling the user for the uplink transmission. The control channel may be embodied as a sub-frame adapted to carry control information that is dependent based on the transmission mode the user is in for scheduling an uplink transmission from the user to the network.

6. A single control channel for signaling control information related to scheduling a user for uplink transmission of packet data in a communication network, comprising:
at least one sub-frame adapted to carry only control information, the control information being based on the transmission mode the user is in for scheduling an uplink transmission from the user to the network, the control information being transmitted over the single control channel, a physical structure of the sub-frame and a data arrangement in the sub-frame being selected based on a user transmission mode, the sub-frame includes a plurality of slots, each slot containing a plurality of fields of control information that differs based on the transmission mode of the user and one of, one or more of medium access control buffer status field, a transport format field, a transport block size field and a redundancy version field, if the user is configured in a scheduled transmission mode, one or more of a transport format field, a transport block size field, a HARQ channel ID field and an indicator indicating whether data carried on a corresponding data channel is a new packet or a re-transmission of a previous packet, if the user is configured in a rate-controlled transmission mode, and one or more of a medium access control (MAC) buffer status field, pilot transmit power field and a priority data field related to priority of a packet in the MAC buffer, if the user is configured in a reporting mode. - View Dependent Claims (7, 8, 9, 10, 11, 12, 14)

13. A method of receiving control signals in a communication network, comprising:
receiving only control signal data related to scheduling for uplink transmission of packet data over a single control channel, the single control channel having physical structure and data arrangement therein corresponding to the control signal data transmitted on the single control channel, the physical structure of the control channel and the data arrangement in the control channel being selected based on a user transmission mode, the receiving of the control signal data includes one of, receiving one or more of medium access control buffer status data, transport format data, transport block size data and redundancy data, if the transmission mode is a scheduled transmission mode, receiving one or more of, transport format data, transport block size data, HARQ channel ID data and an indicator indicating whether data carried on a corresponding data channel is a new packet or a re-transmission of a previous packet, if the transmission mode is a rate-controlled transmission mode, and receiving one or more of medium access control (MAC) buffer status data, pilot transmit power data and data related to priority of a packet in the MAC buffer, if a user is configured in a reporting mode.
