US 8,553,628 B2 · Scheduling method and apparatus for spatial reuse

Abstract

A scheduling method of giving a chance for transmission to a plurality of terminals in the same time period, and a device therefor are provided. The scheduling method includes: transmitting first scheduling information to terminals in a network, the first scheduling information defining transmitting/receiving terminals and a transmission time period; receiving channel measurement information including inter-terminal interference information from the terminals in the network; and generating second scheduling information defining transmission time periods and a plurality of transmitting/receiving terminals that do not interfere with each other by using the channel measurement information.

Claims25

Dependent claims

A scheduling method of a control station for spatial reuse comprising:

transmitting first scheduling information requesting at least one terminal in a network to perform channel measurement;
receiving channel measurement information for spatial reuse from the terminals in the network;
and
generating second scheduling information allocating a new resource to overlap an existing resource allocation area to at least one terminal pair that do not interfere with each other by using the channel measurement information,
wherein the generating of the second scheduling information includes if it is determined as the analyzed result of the channel measurement information that ACK message transmission of a reception terminal interrupts data transmission of a new terminal pair, generating the second scheduling information informing that the ACK message transmission of the reception terminal is restricted.

2 more elements

A terminal device that supports scheduling for spatial reuse, comprising:

a channel measuring unit configured to measure a transmission channel of a transmission terminal and a reception terminal when the terminal device is not defined as the transmission terminal or the reception terminal in scheduling information received from a control station;
an information transmitting unit configured to transmit channel measurement information according to the measurement results to the control station, and to perform data transmission or ACK message transmission in a transmission time period defined in the scheduling information when the terminal device is defined as the transmission terminal or the reception terminal in the scheduling information;
and
wherein the information transmitting unit is further configured to switch a current ACK message transmission policy to another predetermined ACK message transmission policy when the scheduling information includes information representing that ACK message transmission of the terminal device is restricted.
