Abstract
Disclosed is a technology for improving paging efficiency in a communication system by implementing a new paging method (scheme) of minimizing signaling load of a radio section and accurately and rapidly performing paging without performance deterioration when paging is performed in a MIMO communication system.
Claims10
An apparatus of a Base Station (BS), the apparatus comprising:
- an identification unit configured to identify, for a terminal to be paged, a paging ID of a paging group to which the terminal to be paged belongs;
- a transmission unit configured to transmit the identified paging ID of the paging group in different directions through a beam sweeping operation for transmitting beamformed signals in different directions through a plurality of antenna beams;
- and
- a paging performance unit configured to identify the terminal to be paged among terminals receiving the paging ID of the paging group, based on paging-related information returned from the terminal receiving the paging ID of the paging group and perform a paging procedure for the identified terminal to be paged,
- wherein the paging performance unit is configured to recognize a specific antenna beam which the terminal to be paged is able to receive a downlink, based on the paging-related information returned from the terminal to be paged and perform the paging procedure for the terminal to be paged through the recognized specific antenna beam,
- wherein the paging performance unit is configured to recognize, as the specific antenna beam, an antenna beam of a specific time slot related to uplink resources through which the paging-related information is returned from the terminal to be paged among the plurality of time slots of paging resources pre-allocated to the terminal to be paged, and
- wherein the paging-related information comprises terminal identification information, and wherein the paging ID is defined to have a size smaller than that of the terminal identification information for identifying the terminal to be paged.
4 more elements
A method of performing paging by a Base Station (BS) apparatus, the method comprising:
- identifying, for a terminal to be paged, a paging ID of a paging group to which the terminal to be paged belongs;
- transmitting the identified paging ID of the paging group in different directions through a beam sweeping operation for transmitting beamformed signals in different directions through a plurality of antenna beams;
- and
- identifying the terminal to be paged among terminals receiving the paging ID of the paging group, based on paging-related information returned from the terminal receiving the paging ID of the paging group performing a paging procedure for the identified terminal to be paged,
- wherein the performing the paging procedure comprises:
- recognizing a specific antenna beam which the terminal to be paged is able to receive a downlink, based on the paging-related information returned from the terminal to be paged and performing the paging procedure for the terminal to be paged through the recognized specific antenna beam, and
- recognizing, as the specific antenna beam, an antenna beam of a specific time slot related to uplink resources through which the paging-related information is returned from the terminal to be paged among a plurality of time slots of paging resources pre-allocated to the terminal to be paged, and
- wherein the paging-related information comprises terminal identification information, and wherein the paging ID is defined to have a size smaller than that of the terminal identification information for identifying the terminal to be paged.
5 more elements
An apparatus of a terminal, the apparatus comprising:
- a monitoring unit configured to monitor reception of a paging ID in pre-allocated paging resources;
- and
- a paging-related information return unit configured to, when receiving the paging ID, return paging-related information indicating a specific antenna beam which the apparatus of the terminal is able to receive a downlink, thereby when the apparatus of the terminal is a terminal to be paged, a Base Station (BS) transmitting the paging ID being able to identify the apparatus of the terminal as the terminal to be paged, based on the paging-related information and perform a paging procedure for the apparatus of the terminal,
- wherein the paging-related information comprises terminal identification information of the apparatus of the terminal, and the paging-related information return unit is configured to return the paging-related information through uplink resources related to a time slot for receiving the paging ID among a plurality of time slots of the pre-allocated paging resources, and
- wherein the paging ID is defined to have a size smaller than that of the terminal identification information for identifying the terminal.
2 more elements
A method of supporting paging of a terminal apparatus, the method comprising:
- monitoring reception of a paging ID in pre-allocated paging resources;
- and
- returning, when the paging ID is received, paging-related information indicating a specific antenna beam which the apparatus of the terminal is able to receive a downlink, thereby when the apparatus of the terminal is the terminal to be paged, a Base Station (BS) transmitting the paging ID being able to identify the apparatus of the terminal as a terminal to be paged, based on the paging-related information and perform a paging procedure for the apparatus of the terminal,
- wherein the paging-related information comprises terminal identification information of the apparatus of the terminal, wherein the paging ID is defined to have a size smaller than that of the terminal identification information for identifying the terminal;
- and
- the returning comprises;
- returning the paging-related information through uplink resources related to a time slot for receiving the paging ID among the plurality of time slots of the pre-allocated paging resources.
