Initial connection establishment in a wireless communication system

A user equipment used in initiating a wireless connection and subsequent communication over a shared physical resource in a wireless communication system between the user equipment and network equipment, the user equipment comprising:

• a memory having executable program code stored therein;
• and
• a processor coupled to the memory;
• wherein the program code, when executed by the processor, is operable for:
• deriving a temporary identifier to be used by the network equipment to address the user equipment, wherein the temporary identifier is derived by selecting a temporary identifier from a plurality of temporary identifiers based on information received by the user equipment from the network equipment, and wherein the temporary identifier further comprises a component that is a function of time or radio frame number;
• deriving a channel set of at least one downlink channel for the user equipment to receive communications from the network equipment;
• transmitting an initial message to the network equipment, the initial message conveying the temporary identifier;
• receiving a downlink message using the channel set, wherein the downlink message conveys the temporary identifier and a description of a scheduled resource on a shared channel, the scheduled resource comprising a resource allocated to the user equipment by the network equipment;
• and
• communicating data on the scheduled resource in response to the downlink message.

A user equipment used in initiating a wireless connection and subsequent communication over a shared physical resource in a wireless communication system between the user equipment and network equipment, wherein the user equipment is configured to:

• derive a temporary identifier to be used by the network equipment to address the user equipment, wherein the temporary identifier is derived by selecting a temporary identifier from a plurality of temporary identifiers based on information received by the user equipment from the network equipment, and wherein the temporary identifier further comprises a component that is a function of time or radio frame number;
• derive a channel set of at least one downlink channel for the user equipment to receive communications from the network equipment;
• transmit an initial message to the network equipment, the initial message conveying the temporary identifier;
• receive a downlink message using the channel set, wherein the downlink message conveys the temporary identifier and a description of a scheduled resource on a shared channel, the scheduled resource comprising a resource allocated to the user equipment by the network equipment;
• and
• communicate data on the scheduled resource in response to the downlink message.

A network equipment used in initiating a wireless connection and subsequent communication over a shared physical resource in a wireless communication system between user equipment and the network equipment, wherein the network equipment is configured to:

• receive an initial message sent by the user equipment wherein the initial message conveys a temporary identifier derived by a user equipment to be used by the network equipment to address the user equipment, wherein the temporary identifier is selected by the user equipment from a plurality of temporary identifiers based on information transmitted to the user equipment by the network equipment and further comprises a component that is a function of time or radio frame number;
• allocate a scheduled resource to the user equipment, the scheduled resource comprising a resource on a shared channel;
• transmit a downlink message using a channel set derived by the user equipment, the downlink message conveying the temporary identifier and a description of the scheduled resource;
• and
• communicate data on the scheduled resource.

A method of initiating a wireless connection and subsequent communication over a shared physical resource in a wireless communication system between user equipment and network equipment, the method comprising, at the network equipment:

• receiving an initial message sent by the user equipment wherein the initial message conveys a temporary identifier derived by a user equipment to be used by the network equipment to address the user equipment, wherein the temporary identifier is selected by the user equipment from a plurality of temporary identifiers based on information transmitted to the user equipment by the network equipment and further comprises a component that is a function of time or radio frame number;
• allocating a scheduled resource to the user equipment, the scheduled resource comprising a resource on a shared channel;
• transmitting a downlink message using a channel set derived by the user equipment, the downlink message conveying the temporary identifier and a description of the scheduled resource;
• and
• communicating data on the scheduled resource.

A control circuit for use in user equipment used in initiating a wireless connection and subsequent communication over a shared physical resource in a wireless communication system between the user equipment and network equipment, the control circuit being configured to:

• derive a temporary identifier to be used by the network equipment to address the user equipment, wherein the temporary identifier is derived by selecting a temporary identifier from a plurality of temporary identifiers based on information received by the user equipment from the network equipment, and wherein the temporary identifier further comprises a component that is a function of time or radio frame number;
• derive a channel set of at least one downlink channel for the user equipment to receive communications from the network equipment;
• transmit an initial message to the network equipment, the initial message conveying the temporary identifier;
• receive a downlink message using the channel set, wherein the downlink message conveys the temporary identifier and a description of a scheduled resource on a shared channel, the scheduled resource comprising a resource allocated to the user equipment by the network equipment;
• and
• communicate data on the scheduled resource in response to the downlink message.
