Radio resource allocation

A method of indicating a capability of a terminal in a radio system wherein radio resources to be allocated to the 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 performed by the terminal, comprising:

• transmitting, by the terminal, a random access preamble;
• receiving a first random access response assigning a first set of radio resources compatible with the first type of terminal if the terminal is 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 if the terminal is the second type of terminal,
• wherein the first random access response is scheduled differently at least in time or frequency to the second random access response;
• transmitting a connection request message on the first set of radio resources if the terminal is the first type of terminal;
• and
• transmitting the connection request message on the second set of radio resources if the terminal is the second type of terminal,
• wherein the first set of radio resources are located on a same component carrier as the second set of radio resources, and
• wherein the radio resources to be allocated extend over a bandwidth B having a portion of bandwidth B0, where B0<B, and two extending segments on either side of the portion of bandwidth B0, the portion of bandwidth B0 corresponding to the first set of radio resources, and the two extending segments corresponding to the second set of radio resources.

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

• a transceiver configured to:
• receive a random access preamble from the terminal;
• transmit 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 at least in time or frequency to the second random access response;
• and
• receive a connection request message from the terminal;
• and a processor configured to:
• determine that the terminal is the first type of terminal if the connection request message is received on the first set of radio resources, and that the terminal is a second type of terminal if the connection request message is received on the second set of radio resources,
• wherein the first set of radio resources are located on a same component carrier as the second set of radio resources, and
• wherein the radio resources to be allocated extend over a bandwidth B having a portion of bandwidth B0, where B0<B, and two extending segments on either side of the portion of bandwidth B0, the portion of bandwidth B0 corresponding to the first set of radio resources, and the two extending segments corresponding to the second set of radio resources.

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

• a transceiver configured to:
• transmit a random access preamble to a base station,
• receive a first random access response assigning a first set of radio resources compatible with the first type of terminal if the terminal is 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 if the terminal is not the first type of terminal;
• wherein the first random access response is scheduled differently at least in time or frequency to the second random access response;
• transmit a connection request message on the first set of radio resources if the terminal is the first type of terminal;
• and
• transmit the connection request message on the second set of radio resources, if the terminal is not the first type of terminal,
• wherein the first set of radio resources are located on a same component carrier as the second set of radio resources, and
• wherein the radio resources to be allocated extend over a bandwidth B having a portion of bandwidth B0, where B0<B, and two extending segments on either side of the portion of bandwidth B0, the portion of bandwidth B0 corresponding to the first set of radio resources, and the two extending segments corresponding to the second set of radio resources.
