Abstract
In a wireless communication system where different frequency bands are deployed to generate various communication zones, pilot signal set management for a plurality of pilot signals generated from an additional coverage zone is based on identifying a preselected signal set from the plurality of pilot signals and determining whether a predetermined criterion is met.
Claims26
A method of communications operable by an infrastructure entity, comprising:
- receiving from a user entity information for a plurality of pilot signal sets;
- identifying one of the pilot signal sets as a pilot signal set from an additional coverage zone;
- determining a predetermined criterion is met;
- and
- sending an instruction to the user entity to add the pilot signal set from the additional coverage zone and another pilot signal set which is also from the additional coverage zone to the active set of the user entity.
A method of communications operable by a user entity, comprising:
- sending information of a plurality of pilot signal sets to an infrastructure entity, wherein one of the pilot signal sets is a signal set from an additional coverage zone;
- and
- receiving an instruction from the infrastructure entity to add the pilot signal set from the additional coverage zone to the active set of the user entity when a predetermined criterion is met, and add at least one other pilot signal set from the additional coverage zone to the active set.
An infrastructure entity operable in a communication system, comprising:
- means for receiving from a user entity information for a plurality of pilot signal sets;
- means for identifying one of the pilot signal sets as a pilot signal set from an additional coverage zone;
- means for determining a predetermined criterion is met;
- and
- means for sending an instruction to the user entity to add the pilot signal set from the additional coverage zone and another pilot signal set which is also from the additional coverage zone to the active set of the user entity.
A user entity operable in a communication system, comprising:
- means for sending information of a plurality of pilot signal sets to an infrastructure entity, wherein one of the pilot signal sets is a signal set from an additional coverage zone;
- and
- means for receiving an instruction from the infrastructure entity to add the pilot signal set from the additional coverage zone to the active set of the user entity when a predetermined criterion is met, and add at least one other pilot signal set from the additional coverage zone to the active set.
An apparatus operable in a communication system, comprising:
- circuitry configured to:
- receive from a user entity information for a plurality of pilot signal sets;
- identify one of the pilot signal sets as a pilot signal set from an additional coverage zone;
- determine a predetermined criterion is met;
- and
- send an instruction to the user entity to add the pilot signal set from the additional coverage zone and another pilot signal set which is also from the additional coverage zone to the active set of the user entity.
An apparatus operable in a communication system, comprising:
- circuitry configured to:
- send information of a plurality of pilot signal sets to an infrastructure entity, wherein one of the pilot signal sets is a signal set from an additional coverage zone;
- and
- receive an instruction from the infrastructure entity to add the pilot signal set from the additional coverage zone to the active set of the user entity when a predetermined criterion is met, and add at least one other pilot signal set from the additional coverage zone to the active set.
A computer program product, comprising:
- a computer-readable medium physically embodied with computer-readable program code for:
- receiving from a user entity information for a plurality of pilot signal sets;
- identifying one of the pilot signal sets as a pilot signal set from an additional coverage zone;
- determining a predetermined criterion is met;
- and
- sending an instruction to the user entity to add the pilot signal set from the additional coverage zone and another pilot signal set which is also from the additional coverage zone to the active set of the user entity.
