Embodiment mono-
The embodiment of the present invention one provides a kind of sending method based on user-specific reference signal (UERS), and as shown in Figure 5, the method comprises the following steps:
Step 501, network equipment is determined transmission mode and antenna port configuration.
In the embodiment of the present invention, network equipment determines that the process of transmission mode comprises:
Mode one, when transmission mode is while being configurable, network equipment can directly be determined transmission mode according to configuring condition.For example, transmission mode can or send diversity transmission mode for precoding transmission mode, and when network equipment configuration transmission mode is precoding transmission mode, network equipment determines that transmission mode is precoding transmission mode; When network equipment configuration transmission mode is while sending diversity transmission mode, network equipment determines that transmission mode is to send diversity transmission mode.
It should be noted that, when transmission mode is configurable, network equipment also needs by high-level signaling (for semi-static high-level signaling), the information of the transmission mode of configuration to be notified to subscriber equipment; For example, when network equipment configuration transmission mode is precoding transmission mode, need by high-level signaling, the information of precoding transmission mode to be notified to subscriber equipment; Network equipment configuration transmission mode is while sending diversity transmission mode, needs by high-level signaling, the information that sends diversity transmission mode to be notified to subscriber equipment.
Mode two, when transmission mode is when making an appointment, network equipment according to a preconcerted arrangement situation directly determine transmission mode.For example, arrange transmission mode while being precoding transmission mode in agreement, network equipment directly determines that transmission mode is precoding transmission mode; While arranging transmission mode for transmission diversity transmission mode in agreement, network equipment directly determines that transmission mode is for sending diversity transmission mode.
In the embodiment of the present invention, network equipment determines that the process of antenna port configuration comprises:
Mode one, when antenna port is configured to when configurable, network equipment can directly be determined antenna port configuration according to configuring condition.For example, antenna port configuration can be antenna port 7 or antenna port 8, and when network equipment configuration antenna port is configured to antenna port 7, network equipment determines that antenna port is configured to antenna port 7; When network equipment configuration antenna port is configured to antenna port 8, network equipment determines that antenna port is configured to antenna port 8.
It should be noted that, at antenna port, configure when configurable, network equipment also needs by high-level signaling (for semi-static high-level signaling), the information of the antenna port configuration of configuration to be notified to subscriber equipment; For example, when network equipment configuration antenna port is configured to antenna port 7, need by high-level signaling, the information of antenna port 7 to be notified to subscriber equipment; When network equipment configuration antenna port is configured to antenna port 8, need by high-level signaling, the information of antenna port 8 to be notified to subscriber equipment.
Mode two, when antenna port is configured to make an appointment, network equipment according to a preconcerted arrangement situation directly determine antenna port configuration.For example, arrange an antenna port while being configured to antenna port 7 in agreement, network equipment determines that an antenna port is configured to antenna port 7; In agreement, arrange two antenna ports while being configured to antenna port 7 and antenna port 9, network equipment determines that two antenna ports are configured to antenna port 7 and antenna port 9.
It should be noted that, in aforesaid way one and mode two, when the configuration of configuration antenna port or the configuration of agreement antenna port, it is also conceivable that the situation of transmission mode, for example, when transmission mode is precoding transmission mode, antenna port transmission data if, the network equipment antenna port that can configure or make an appointment is configured to antenna port 7; When transmission mode is when sending diversity transmission mode, two antenna ports transmission data if, the network equipment antenna port that can configure or make an appointment is configured to antenna port 7 and antenna port 9.
Mode three, network equipment are directly determined antenna port configuration according to transmission mode.Wherein, different transmission modes is by the antenna port configuration corresponding to different.For example, when transmission mode is precoding transmission mode, an antenna port transmits data if, and network equipment determines that antenna port is configured to antenna port 7 or antenna port 8; Two antenna ports transmit data if, and network equipment determines that antenna port is configured to antenna port 7 and antenna port 8; Again for example, when transmission mode is that while sending diversity transmission mode, two antenna ports transmit data if, network equipment determines that antenna port is configured to antenna port 7 and antenna port 9, or is antenna port 7 and antenna port 8; Four antenna ports transmit data if, and network equipment determines that antenna port is configured to antenna port 7, antenna port 8, antenna port 9, antenna port 10.
As shown in Figure 6, while sending diversity transmission mode for adopting, two antenna ports are configured to antenna port 7 and antenna port 9, take different resources, the pilot tone pattern schematic diagram of UERS under 2 antenna ports that the mode of employing frequency division is distinguished.
Further, in extended cyclic prefix CP situation, owing to only having at present antenna port 7 and antenna port 8, while therefore sending diversity transmission mode, can still adopt antenna port 7 and antenna port 8, when transmission mode is while sending diversity transmission mode, two antenna ports transmit data if, and network equipment determines that antenna port is configured to antenna port 7 and antenna port 8.Certainly, in practical application, can redesign the two antenna port pilot tone patterns that take different resource, which does not repeat them here yet.
In the said process of the embodiment of the present invention, the parameter that the parameter that represents transmission mode is user class or the parameter of cell-level.The parameter that the parameter that represents antenna port configuration is user class or the parameter of cell-level.
Step 502, network equipment sends UERS and data-signal according to this transmission mode and antenna port configuration to subscriber equipment.For example, network equipment utilizes transmission mode to carry out precoding to data or dispensing diversity is processed, and to the signal after subscriber equipment transmission processing.

Further, after the ratio at network equipment specified data power with respect to UERS power, network equipment also needs to judge whether data power to be notified to subscriber equipment with respect to the ratio of UERS power; When QPSK for data acquisition (Quadrature Phase Shift Keying, Quadrature Phase Shift Keying) modulates, network equipment is determined does not need data power to notify to subscriber equipment with respect to the ratio of UERS power; When data acquisition is used high order modulation, network equipment is determined and data power need to be notified to subscriber equipment with respect to the ratio of UERS power, and by high-level signaling, data power is notified to subscriber equipment with respect to the ratio of UERS power.In said process, network equipment, when data power being notified to subscriber equipment with respect to the ratio of UERS power by high-level signaling, can also be notified the absolute power of UERS to subscriber equipment together by this high-level signaling.
In the said process of the embodiment of the present invention, represent parameter that data power is user class with respect to the parameter of the ratio of UERS power or the parameter of cell-level; The parameter that the parameter that represents the absolute power of UERS is user class or the parameter of cell-level.
It should be noted that, data power only just needs notifying user equipment with respect to the ratio of UERS power when data are used high order modulation, if control signal adopts QPSK modulation, subscriber equipment does not need with reference to this data power the ratio with respect to UERS power when Data Detection, if therefore E-PDCCH only adopts QPSK modulation, network equipment does not need this data power of notifying user equipment with respect to the information of the ratio of UERS power, i.e. the ratio with respect to UERS power without definition data power.
If E-PDCCH adopts high order modulation (as 16QAM), adopt power ascension technology, need notification data power with respect to the ratio of UERS power or/and the absolute power of UERS, this notice signaling can be semi-static high-level signaling.It should be noted that in this situation, need the data power stipulated in Standard modification and the identical hypothesis of power of UERS; For example, when interpolation E-PDCCH sends diversity transmission based on user-specific reference signal, identical without the power of tentation data power and UERS.
In sum, in the embodiment of the present invention, by a kind of sending method based on user-specific reference signal is provided, and configure or/and transmitted power by the antenna port of the exclusive reference signal of rational configure user, can improve the accuracy of channel estimating, thereby improve the performance of Data Detection.

It should be noted that, in aforesaid way one and mode two, when the configuration of configuration antenna port or the configuration of agreement antenna port, it is also conceivable that the situation of transmission mode, for example, when transmission mode is precoding transmission mode, antenna port transmission data if, the network equipment antenna port that can configure or make an appointment is configured to antenna port 7; When transmission mode is when sending diversity transmission mode, two antenna ports transmission data if, the network equipment antenna port that can configure or make an appointment is configured to antenna port 7 and antenna port 9.
Mode three, subscriber equipment are directly determined antenna port configuration according to transmission mode.Different transmission modes is by the antenna port configuration corresponding to different.For example, when transmission mode is precoding transmission mode, an antenna port transmits data if, and subscriber equipment determines that antenna port is configured to antenna port 7 or antenna port 8; Two antenna ports transmit data if, and subscriber equipment determines that antenna port is configured to antenna port 7 and antenna port 8; Again for example, when transmission mode is that while sending diversity transmission mode, two antenna ports transmit data if, subscriber equipment determines that antenna port is configured to antenna port 7 and antenna port 9, or is antenna port 7 and antenna port 8; Four antenna ports transmit data if, and subscriber equipment determines that antenna port is configured to antenna port 7, antenna port 8, antenna port 9, antenna port 10.
