Radio resource allocation

A method of indicating terminal capability in a radio system wherein the radio resources to be allocated to an terminal include a set of radio resources incompatible with a first type of terminal and compatible with at least a second type of terminal, the method comprising:

• transmitting a random access preamble;
• receiving a first random access response assigning a first set of radio resources compatible with the first type of terminal in the case where the terminal is of the first type of terminal and a second random access response assigning a second set of radio resources incompatible with the first type of terminal in the case where the terminal is not of the first type of terminal;
• wherein the first random access response is scheduled differently in time and/or frequency to the second access response;
• transmitting a connection request message on the first set of radio resources in the case where the terminal is a terminal of the first type;
• otherwise transmitting the connection request message on the second set of radio resources, if the terminal is not of the first type.

A method of indicating terminal capability in a radio system wherein the radio resources to be allocated to a terminal include resources incompatible with a first type of terminal, the method comprising:

• receiving random access resource information;
• selecting random access resources for transmission of a random access preamble based on the capability of the terminal;
• transmitting a random access preamble using the selected random access resources;
• wherein if the terminal is of a first type of terminal the terminal selects a first set of random access resources compatible with the first type of terminal and wherein if the terminal is of a second type of terminal the terminal selects a second set of random access resources incompatible with the first type of terminal.

A network entity for allocating radio resources to a terminal according to the capability of the terminal wherein the radio resources to be allocated include resources incompatible with a first type of terminal, the network entity comprising:

• a transceiver for
• detecting a random access preamble from a terminal,
• transmitting a first random access response assigning a first set of radio resources compatible with the first type of terminal and a second random access response assigning a second set of radio resources incompatible with the first type of terminal;
• wherein the first random access response is scheduled differently in time and/or frequency to the second access response;
• receiving a connection request message from the terminal;
• and
• a processor for determining that the terminal is a terminal of the first type when the connection request message is received on the first set of radio resources and that the terminal is not of the first type when the connection request message is received on the second set of radio resources.

A user entity in a radio system wherein the radio resources to be allocated at a terminal include at least one set of resources incompatible with a first type of terminal, the terminal comprising:

• a transceiver for
• transmitting a random access preamble to a base station,
• receiving a first random access response assigning a first set of radio resources compatible with the first type of terminal in the case where the terminal is of the first type of terminal and a second random access response assigning a second set of radio resources incompatible with the first type of terminal in the case where the terminal is not of the first type of terminal;
• wherein the first random access response is scheduled differently in time and/or frequency to the second access response;
• transmitting a connection request message on the first set of radio resources in the case where the terminal is a terminal of the first type;
• otherwise
• transmitting the connection request message on the second set of radio resources, if the terminal is not of the first type.

A user entity in a radio system wherein the radio resources to be allocated at a terminal include at least one set of resources incompatible with a first type of terminal, the terminal comprising:

• a transceiver for
• receiving random access resource information
• a processor for selecting random access resources for transmission of a random access preamble based on the capability of the terminal;
• wherein the transceiver is operable to transmit a random access preamble using the selected random access resources;
• and
• the processor is operable to select random access resources compatible with the first type of terminal if the terminal is of a first type of terminal, and to select random access resources incompatible with the first type of terminal if the terminal is not of a first type of terminal.
