Embodiment one
The embodiment of the invention one provides a kind of sending method based on user-specific reference signal (UERS), and is as shown in Figure 5, and this method may further comprise the steps:
In the embodiment of the invention, network equipment confirms that the process of transmission mode comprises:
Mode one, when transmission mode when being configurable, then network equipment can directly be confirmed transmission mode according to configuring condition.For example, transmission mode can or be sent diversity transmission mode for the precoding transmission mode, and when network equipment configuration transmission mode was the precoding transmission mode, then network equipment confirmed that transmission mode is the precoding transmission mode; When network equipment configuration transmission mode was the transmission diversity transmission mode, then network equipment confirmed that transmission mode is to send diversity transmission mode.
Need to prove that when transmission mode was configurable, network equipment also need be notified the information of the transmission mode of configuration to subscriber equipment through high-level signaling (for semi-static high-level signaling); For example, when network equipment configuration transmission mode is the precoding transmission mode, then need the information of precoding transmission mode be notified to subscriber equipment through high-level signaling; Network equipment configuration transmission mode then need be notified to subscriber equipment through the information that high-level signaling will send diversity transmission mode when sending diversity transmission mode.
Mode two, when transmission mode when making an appointment, then network equipment according to a preconcerted arrangement situation directly confirm transmission mode.For example, when the agreement transmission mode was the precoding transmission mode in agreement, then network equipment confirmed that directly transmission mode is the precoding transmission mode; When the agreement transmission mode was for the transmission diversity transmission mode in agreement, then network equipment confirmed that directly transmission mode is for sending diversity transmission mode.
In the embodiment of the invention, network equipment confirms that the process of antenna port configuration comprises:
Mode one, when antenna port is configured to when configurable, then network equipment can directly be confirmed the antenna port configuration according to configuring condition.For example, the antenna port configuration can be antenna port 7 or antenna port 8, and when network equipment configuration antenna port was configured to antenna port 7, then network equipment confirmed that antenna port is configured to antenna port 7; When network equipment configuration antenna port was configured to antenna port 8, then network equipment confirmed that antenna port is configured to antenna port 8.
Need to prove, dispose when configurable that network equipment also need be notified the antenna port information configured of configuration to subscriber equipment through high-level signaling (for semi-static high-level signaling) at antenna port; For example, when network equipment configuration antenna port is configured to antenna port 7, then need the information of antenna port 7 be notified to subscriber equipment through high-level signaling; When network equipment configuration antenna port is configured to antenna port 8, then need the information of antenna port 8 be notified to subscriber equipment through high-level signaling.
Mode two, when antenna port is configured to make an appointment, then network equipment according to a preconcerted arrangement situation directly confirm the antenna port configuration.For example, when agreement one antenna port was configured to antenna port 7 in agreement, then network equipment confirmed that an antenna port is configured to antenna port 7; When agreement two antenna ports were configured to antenna port 7 with antenna port 9 in agreement, then network equipment confirmed that two antenna ports are configured to antenna port 7 and antenna port 9.
Need to prove; In aforesaid way one and the mode two, when 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 was the precoding transmission mode, if be antenna port transmission data, then the network equipment antenna port that can dispose or make an appointment was configured to antenna port 7; When transmission mode when sending diversity transmission mode, if be two antenna ports transmission data, then the network equipment antenna port that can dispose or make an appointment is configured to antenna port 7 and antenna port 9.
Mode three, network equipment are directly confirmed the antenna port configuration according to transmission mode.Wherein, different transmission modes will be corresponding to the different antennas port arrangement.For example, when transmission mode was the precoding transmission mode, if be antenna port transmission data, then network equipment confirmed that antenna port is configured to antenna port 7 or antenna port 8; If be two antenna ports transmission data, then network equipment confirms that antenna port is configured to antenna port 7 and antenna port 8; Again for example, when transmission mode was the transmission diversity transmission mode, if be two antenna ports transmission data, then network equipment confirmed that antenna port is configured to antenna port 7 and antenna port 9, or is antenna port 7 and antenna port 8; If be four antenna ports transmission data, then network equipment confirms that antenna port is configured to antenna port 7, antenna port 8, antenna port 9, antenna port 10.
As shown in Figure 6, when 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 sketch map of UERS under 2 antenna ports that the mode of employing frequency division is distinguished.
Further; Under extended cyclic prefix CP situation; Owing to having only antenna port 7 and antenna port 8 at present, can still adopt antenna port 7 and antenna port 8 when therefore sending diversity transmission mode, promptly when transmission mode is the transmission diversity transmission mode; If be two antenna ports transmission data, then network equipment confirms that antenna port is configured to antenna port 7 and antenna port 8.Certainly, in the practical application, also can design the two antenna port pilot tone patterns that take different resource again, this mode repeats no more at this.
In the said process of the embodiment of the invention, the parameter of expression transmission mode is the parameter of user class or the parameter of cell-level.The parameter of expression antenna port configuration is the parameter of user class or the parameter of cell-level.
