Abstract
Embodiments provide a terminal control method, a radio network controller, and a base station. The method includes: determining, by an RNC, that a downlink serving base station of a terminal that establishes a connection with both a macro base station and a micro base station is the macro base station; acquiring, by the RNC, a target power control value, where the target power control value can be used to ensure that channel quality of an uplink control channel from the terminal to the macro base station reaches a target threshold; and sending, by the RNC, the target power control value to the micro base station.
Claims15
A method, comprising:
- acquiring, by a micro base station, a target power control value sent by a radio network controller (RNC), wherein the target power control value is used to ensure that channel quality of a first uplink control channel from a first terminal to a macro base station reaches a target threshold, and wherein a heterogeneous network comprises the micro base station, the RNC, and the macro base station;
- controlling, by the micro base station according to the target power control value, uplink transmit power of the first terminal, wherein the first terminal establishes a connection with both the macro base station and the micro base station, and wherein a downlink serving base station of the first terminal is the macro base station;
- after controlling the uplink transmit power of the first terminal, receiving, by the micro base station, user information of a second terminal in an adjacent cell of the micro base station, wherein the user information of the second terminal is sent by the RNC;
- and
- canceling, according to the user information of the second terminal, a target uplink interference signal of the first terminal from an uplink signal of the first terminal that is received by the micro base station.
2 more elements
A radio network controller (RNC), comprising:
- a non-transitory memory that stores at least one program code;
- and
- at least one computing hardware configured to cause, through execution of the at least one program code, the RNC to:
- acquire a target power control value when it is determined that a downlink serving base station of a first terminal is a macro base station, wherein the target power control value is used to ensure that channel quality of an uplink control channel from the first terminal to the macro base station reaches a target threshold, and wherein the first terminal establishes a connection with both the macro base station and a micro base station;
- send the target power control value to the micro base station for the micro base station to use to control uplink transmit power of the first terminal according to the target power control value;
- and
- send user information of a second terminal in an adjacent cell of the micro base station to the micro base station, causing the micro base station to cancel, according to the user information of the second terminal, a target uplink interference signal of the first terminal from an uplink signal of the first terminal that is received by the micro base station.
4 more elements
A base station, comprising:
- at least one non-transitory memory to store at least one program code;
- and
- at least one computing hardware to cause, through execution of the at least one program code, the base station to:
- acquire a target power control value sent by an radio network controller (RNC), wherein the target power control value is used to ensure that channel quality of a first uplink control channel from a first terminal to a macro base station reaches a target threshold;
- control uplink transmit power of the first terminal according to the target power control value, wherein the first terminal establishes a connection with both the macro base station and the base station, and a downlink serving base station of the first terminal is the macro base station;
- receive user information of a second terminal in an adjacent cell of the base station, wherein the user information is sent by the RNC;
- and
- cancel, according to the user information, a target uplink interference signal of the first terminal from an uplink signal of the first terminal that is received by the base station.
