Abstract
A method for a subscriber station to perform network entry in a multi-carrier wireless environment that has a primary carrier and at least one secondary carrier associated with a base station. The method includes sensing a carrier in an area serviced by the base station and determining if the carrier is a primary carrier or a secondary carrier. The method further includes performing the network entry if the determining establishes that the sensed carrier is a primary carrier and not a secondary carrier.
Claims41
A method for an SS to perform network entry in a multi-carrier wireless environment that has a primary carrier and at least one secondary carrier associated with a BS, the method comprising:
- a. sensing a carrier in an area serviced by the BS;
- b. determining if the carrier is a primary carrier or a secondary carrier;
- c. performing the network entry if the determining establishes that the sensed carrier is a primary carrier and not a secondary carrier.
A method for an SS to perform network entry in a multi-carrier wireless environment that has a plurality of primary carriers and at least one secondary carrier associated with a BS, the method comprising:
- a. receiving at the SS control information sent over one of the primary carriers;
- b. processing with the SS the control information to determine if the network entry is to be performed over the one of the primary carriers or a different primary carrier of the plurality of primary carriers;
- c. performing the network entry on the basis of the determining.
In a multi-carrier wireless environment that has a primary carrier and at least one secondary carrier associated with a BS, the method comprising:
- a. the BS sending over the primary carrier control information to an SS;
- b. the SS initiating in response to the control information a UL ranging with the secondary carrier.
In a multi-carrier wireless environment that has a primary carrier and at least one secondary carrier associated with a BS, a method for delivering system information on the secondary carrier to an SS, the method comprising:
- a. the BS sending over the primary carrier control data to an SS, the control data conveying decoding information;
- b. the SS decoding a broadcast channel of the secondary carrier on the basis of the decoding information.
In a multi-carrier wireless environment that has a plurality of primary carriers and at least one secondary carrier associated with a BS, a method for performing intra-BS handover, the method comprising:
- a. the BS sending to the SS over a first of the plurality of the primary carriers control data;
- b. the SS switching to a second of the plurality of the primary carriers in response to the control data.
