Abstract
According to a resource configuration method, user equipment, and a base station that are provided in embodiments of the present invention and relate to the communications field. A specific solution is as follows: A base station sends M reference signals to UE in N time units in a time unit set, where the reference signal is used by the UE to perform channel quality measurement, and each reference signal in the M reference signals is corresponding to one piece of precoding matrix information. The base station receives channel quality indication information sent by the UE.
Claims20
A method, comprising:
- sending, by a base station, M reference signals to user equipment (UE) in N time units in a time unit set, wherein the M reference signals are used by the UE to perform channel quality measurement, and each reference signal in the M reference signals corresponds to one respective piece of precoding matrix information;
- receiving, by the base station, channel quality indication information sent by the UE, wherein the channel quality indication information is determined by the UE according to the M reference signals;
- selecting, by the base station, an optimal reference signal resource for the UE according to the channel quality indication information;
- and
- sending, by the base station, an optimal reference signal to the UE according to the optimal reference signal resource.
A method, comprising:
- receiving, by user equipment (UE), M reference signals sent by a base station in N time units in a time unit set, wherein each reference signal in the M reference signals corresponds to one respective piece of precoding matrix information;
- reporting channel quality indication information to the base station based on the M reference signals, causing the base station to select an optimal reference signal resource for the UE according to the channel quality indication information;
- and
- receiving an optimal reference signal sent by the base station according to the optimal reference signal resource.
A base station, comprising:
- a transmitter, configured to send M reference signals to user equipment (UE) in N time units in a time unit set, wherein the M reference signals are used by the UE to perform channel quality measurement, and each reference signal in the M reference signals corresponds to one respective piece of precoding matrix information;
- a receiver, configured to receive channel quality indication information sent by the UE, wherein the channel quality indication information is determined by the UE according to the M reference signals;
- a processor;
- and
- a computer-readable storage medium storing a program to be executed by the processor, the program including instructions for:
- selecting an optimal reference signal resource for the UE according to the channel quality indication information;
- and
- wherein the transmitter is further configured to send an optimal reference signal to the UE according to the optimal reference signal resource.
The base station according to claim ii, wherein the channel quality indication information comprises M channel quality measurement results, an optimal channel quality measurement result, or a reference signal number.
The base station according to claim ii, wherein the time unit set is notified by the base station to the UE using higher layer signaling or a control channel.
The base station according to claim ii, wherein the M reference signals comprise a cell-specific reference signal or a user-specific reference signal.
The base station according to claim ii, wherein the time unit set is periodically or non-periodically notified by the base station to the UE.
User equipment, comprising:
- a receiver, configured to receive M reference signals sent by a base station in N time units in a time unit set, wherein each reference signal in the M reference signals corresponds to one respective piece of precoding matrix information;
- a processor;
- and
- a computer-readable storage medium storing a program to be executed by the processor, the program including instructions for:
- reporting channel quality indication information to the base station based on the M reference signals, causing the base station to select an optimal reference signal resource for the UE according to the channel quality indication information;
- and
- wherein the receiver is further configured to receive an optimal reference signal sent by the base station according to the optimal reference signal resource.
