Technical field

The present invention relates to the field of communications technologies, and in particular, to a method, a measurement method, an information sending method, and a device for determining a primary cell or a primary site of a user equipment. Background technique

With the development of communication technology, a new operation scenario, Coordinated Multi-Point (CoMP), is proposed. Coordinated multi-point transmission can improve the rate of data transmission, for example, smooth video transmission. Thereby improving user satisfaction. Currently, whether it is CoMP in a homogeneous website or a homogeneous network with high-power remote radio heads (RRHs), or a heterogeneous network scenario with low-power RRH, in the heterogeneous network. The micro cell may be an independent cell and has an independent cell identifier; or may not be an independent cell, and share a cell identifier with the macro cell. For example, in a heterogeneous network scenario in which a cell identity is shared, different sites transmit different channels when data is transmitted between the network side and the user equipment (UE, User Equipment, also called terminal or user terminal). The Channel State Information Reference Signal (CSI-RS) is used for the UE to perform channel measurement and the like by measuring each CSI-RS. A station is also called a node or a transmission point or an access point, which may be a macro site or a microsite. A macro base station is also called a macro cell base station, and a micro base station is also called a micro cell base station. The micro base station includes but is not limited to pico, femto, etc. . When the data transmission in the CoMP mode is performed between the station and the UE, different stations will transmit different CSI-RSs, and the terminal performs channel estimation on the link between each station and the terminal by measuring each CSI-RS. . In the prior art, although the user equipment can obtain configuration information of at least one CSI-RS from the base station side, the UE and the network station cannot agree on which CSI-RS site to transmit is the primary site, or which CSI is used for sending. The cell of the -RS is the primary cell agreed. When the UE cannot select the primary site, it will not be able to perform measurement or calculation of certain parameters with the primary site as needed, or some signaling interaction.

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings of the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention. In this embodiment, the primary site may also be a primary node, which is used to send control signaling to the user equipment, and is not limited in this embodiment. Referring to FIG. 1, FIG. 1 is a flowchart of a method for determining a primary site or a primary cell of a user equipment according to an embodiment of the present invention; the method is applied to a coordinated multi-point (CoMP) scenario. The CoMP environment may include: a CoMP in a homogeneous website point, and a high-power remote radio head (RRHS,

丄 a homogeneous network of the remote radio head, a heterogeneous network scenario with a low-power RRH, and the like, the method includes: Step 101: Receive at least one signal state information reference signal (CSI-RS, configured for the user equipment, sent by the network side, Channel state information RS) configuration information; in this embodiment, the network side may be an evolved base station (eNB, evolved Node B), or may be a remote radio head RRH, etc., where the eNB indicates that it corresponds to a macro cell. Site, the RRH represents a site corresponding to the micro cell. In addition, the RRH can also be other types of small base stations, for example, ? ₀ , 13⁄41, 13⁄4 or 11 etc. The one or the at least one RRH or the small base station may be connected to the eNB through an optical fiber, or may be connected by using other high-speed transmissions, which is not limited in this embodiment. If the heterogeneous network scenario includes one macro station and two micro stations, the macro station transmits a signal status information reference signal CSI-RS1, the first micro station transmits CSI-RS2, and the second micro station transmits CSI-RS3. The terminal obtains the configuration of the CSI-RS1, CSI-RS2, CSI-RS3 or the three CSI-RS configuration information. The following description uses CSI-RS configuration information as an example. A CSI-RS configuration information (or a CSI-RS configuration, a set of CSI-RSd configuration information) refers to CSI-RS information used by the site, and includes at least one of the following information: CSI-RS sequence Time-frequency resource configuration, transmission period, CSI-RS configuration identifier, CSI-RS configuration index number, antenna port for transmitting the CSI-RS, number of antennas used to transmit the CSI-RS, and number of antennas used by the CSI-RS Frame configuration, CSI-RS resources, and other information. For one terminal, different transmission points send different CSI-RSs to the terminal. That is to say, a CSI-RS comes from a transmission point. The terminal can obtain the CSI-RS (ie, CSI-RS) sent by the transmission point through the configuration information by obtaining configuration information of a CSI-RS (for example, CSI-RS1). Therefore, each CSI-RS configuration information corresponds to one transmission point. Further, the terminal evaluates the signal quality of the link between the terminal and each transmission point by measuring the CSI-RS signal transmitted by each transmission point. In the CoMP communication system, CSI-RS configuration information of different sites can be sent to the terminal through one site. The base station allocates at least one (such as M) CSI-RS configuration information for the user equipment. Specifically, the base station configures a downlink (DL, Downlink) CoMP set for the user equipment, where the CoMP set directly or indirectly provides a set of potential transmission points of the CoMP. The base station provides the CSI-RS configuration corresponding to the transmission point in the CoMP set for the user equipment. The downlink CoMP set may be a CoMP RRM set, a CoMP Resource Management set, a CoMP measurement set, or a CoMP operation set. Generally, the site or the primary node (Anchor node), where the eNB is used as an example, sends at least one CSI-RS configuration information to the user equipment. The eNB may be pre-configured with the user equipment, or actively designated. Determining a transmission point corresponding to one CSI-RS configuration information of the at least one CSI-RS configuration information as a primary node (an primary node, a primary point, etc.), or determining a cell corresponding to the transmission point as a primary site Cell (Primary cel l, Anchor cel l, etc.). The primary site or the primary cell may be configured to send downlink control signaling to the UE. Other stations outside the primary site may have no downlink control channel and therefore cannot send downlink control signaling to the UE. After determining the primary site or the primary cell, the UE may accept downlink control signaling or transmit certain specific information at the primary site or the primary cell. Step 102: Determine a transmission point corresponding to one CSI-RS configuration information of the at least one CSI-RS configuration information as a primary station, or determine a cell corresponding to the transmission point as a primary cell. The step specifically includes: determining, according to the setting, a transmission point corresponding to one CSI-RS configuration information of the at least one CSI-RS configuration information as a primary station that sends control signaling, or determining a primary cell corresponding to the transmission point. Or a cell corresponding to one CSI-RS configuration information specified in the at least one CSI-RS configuration information is determined as a primary site, or a cell corresponding to the transmission point is determined as a primary cell. In this step, when the user equipment receives the at least one CSI-RS configuration information, the CSI-RS configuration information of the at least one CSI-RS configuration information may be preset according to the network side (for example, the default manner). The corresponding transmission point is the primary station that sends the control signaling, or the cell corresponding to the transmission point is the primary cell; or the network side provides the CSI-RS configuration information indicating that the CSI-RS configuration information indicates at least one CSI-RS configuration information. The transmission point is the primary site, or the cell corresponding to the transmission point is the primary cell. Specifically, the CSI-RS (s) configuration information may be provided, and the indication information is carried, indicating that the transmission point corresponding to the CSI-RS configuration information is the primary site, or the cell corresponding to the transmission point is the primary cell. . Of course, the network side may also use the indication information to indicate that the transmission point corresponding to a certain CSI-RS configuration information is the primary station, or the cell corresponding to the transmission point is the primary cell. Specifically, the preset manner may include: determining, as the primary site, a transmission point corresponding to the Nth CSI-RS configuration information configured for the user equipment in the at least one CSI-RS configuration information, or corresponding to the transmission point The cell is determined to be a primary cell, where the Nth CSI-RS configuration information is any one of the at least one CSI-RS configuration information; or, the at least one CSI-RS configuration information is The transmission point corresponding to the CSI-RS configuration information sent on a certain port is determined to be the primary station, or the cell corresponding to the transmission point is determined as the primary cell. That is to say, the network side and the user equipment can make an appointment in advance: setting the first (such as the first or fifth, etc.) CSI-RS configuration information or setting the CSI-RS configuration information sent on a certain port. a transmission point as a primary site, or a cell corresponding to the transmission point as a primary cell; and the user equipment receives at least one CSI-RS When configuring the information, you can directly set the CSI-RS configuration information (such as the first or fifth, etc.) or the CSI sent on the port (such as the first port, etc.) according to the settings. The transmission point corresponding to the RS configuration information is used as the primary site, or the cell corresponding to the transmission point is used as the primary cell. Of course, if the network side and the user equipment do not have an appointment in advance, the network side may also indicate a CSI-RS configuration information in the at least one CSI-RS configuration information or indicate a CSI sent on a certain port in a specified manner. The transmission point corresponding to the RS configuration information is determined to be the primary site, or the cell corresponding to the transmission point is determined to be the primary cell. That is, the network side may add an indication information (such as a bit) to any one of the at least one CSI-RS configuration information that is sent, to indicate that the CSI-RS configuration information is corresponding. The transmission point is the primary site, or the cell corresponding to the transmission point is the primary cell. For example, if the network side sends the first CSI-RS configuration information to the user equipment, and adds a bit in the first CSI-RS configuration information, to indicate that the user equipment is receiving the first CSI-RS configuration. After the information, the transmission point corresponding to the first CSI-RS configuration information is determined as the primary site, or the cell corresponding to the transmission point is determined to be the primary cell, etc., of course, the second or third, etc. . Alternatively, the transmission point corresponding to the CSI-RS configuration information sent on a certain port (such as the second port, etc.) is determined to be the primary site, or the cell corresponding to the transmission point is determined to be the primary cell. There are many ways of indicating, and the invention is not limited. In this embodiment, the primary site (primary point, primary node, anchor point, anchor node, etc.) may include: a downlink transmission point that sends control signaling; or a macro base station or a site corresponding to the macro cell; or The corresponding cell of the primary cell (which may be an anchor cel l , primary cel l, etc.); or the site corresponding to the user equipment serving cell, but is not limited thereto. Of course, the primary site can also be determined in other ways, which is not limited herein. The primary cell (which may be an anchor cel l , primary cel l, etc.) may include: a cell that sends control signaling for the user equipment; or a cell corresponding to a downlink transmission point that sends control signaling; or a cell; or, in a RRC (Radio Resources Control) connection establishment or re-establishment or handover process, a cell that provides non-access stratum (NAS, Non Access Stratum) mobility information for the user equipment, or, in RRC In the connection establishment or handover process, the cell that provides security input for the user equipment, the cell corresponding to the primary node, but is not limited thereto. The security input technology can be specifically referred to the prior art, and details are not described herein. The primary site may be a primary site within a serving cell where the terminal is located, or may be a primary site of a neighboring cell. The primary cell may be a primary cell in a serving cell where the terminal is located, or may be a primary cell in a neighboring cell. For the target cell of the terminal mentioned in the handover process, it is also the neighbor cell of the terminal. For example, in the heterogeneous network scenario, one macro station eNB1 and two micro-sites RRH1, RRH2 are included in the cell 1. The macro station transmits a signal status information reference signal CSI-RS1, the first micro station transmits CSI-RS2, and the second micro station transmits CSI-RS3. The terminal obtains the configuration of the CSI-RS1, CSI-RS2, CSI-RS3 or the three CSI-RS configuration information. Similarly, one macro station eNB2 and two micro stations Pico 1, Pico2 are included in the cell 2. The macro stations eNB1 and eNB2 provide the entire cell coverage, or provide control signaling transmission of the entire cell, or the signal of the macro station is the best in the cell, and thus is determined as the master node. Of course, it is also possible that one of the microsites is determined to be the master node. If the terminal accesses the cell 1, then the cell 2 is the neighbor cell of the terminal, then the eNB1 is the master node of the terminal transmitting the serving cell, and the eNB2 is the master node of the terminal neighbor cell. Example 2, 1 macro site eNB1 and 2 microsites Pico3, pico4. The macro station transmits a signal status information reference signal CSI-RS1, the first micro station transmits CSI-RS2, and the second micro station transmits CSI-RS3. Each of the stations is an independent cell (possibly different in PCI), wherein the cell in which eNB1 works is cell a, the cell in which Pico3 operates is cell b, and the cell in which Pico4 operates is cell c. The three sites provide CoMP services for the terminal. At this time, eNB1 provides control signaling transmission for the terminal, eNB1 is the primary node of the serving cell of the terminal, and cell a provided by eNB1 is the primary cell of the serving cell of the terminal. For the neighbor cell of the terminal (eNB2 and two micro-sites Pico5, pico6), the cell in which eNB2 operates is cell x, the cell in which Pico3 operates is cell y, and the cell in which Pico4 operates is cell z, and eNB2 provides control signaling transmission. Site, eNB2 is the master node of the neighbor cell of the terminal, and cell X served by eNB2 is the master cell of the neighbor cell of the terminal. In the content of the embodiment of the present invention, the primary site may be referred to as a primary node. In the content of the embodiment of the present invention, the protection point is mainly described by taking the primary site of the terminal serving cell and the primary cell under the serving cell as an example.
