Description

Method for generating carrier configuration information, network side equipment, and user equipment

technical field

The present invention relates to the field of mobile wireless communication, in particular to a method for generating carrier configuration information, network side equipment and user equipment when multiple nodes in a wireless communication system are cooperatively transmitting for UE.

Background technique

With the development of the mobile communication industry and the increasing demand for mobile data services, people have higher and higher requirements for the speed and quality of service (Qos) of mobile communication. Therefore, in the third generation mobile communication (3rd generation Generation, 3G) before large-scale commercial use, the research and development of the next-generation mobile communication system has already begun, and the typical one is the long-term evolution initiated by the 3rd Generation Partnership Project (3GPP). (Long Term Evolution, LTE) project, the highest spectrum bandwidth that the LTE system can provide is 20MHz (megahertz). With the further evolution of the network, LTE-A (Evolved LTE), as an evolution system of LTE, can provide up to 100MHz of spectrum bandwidth and support more flexible and higher-quality communications. At the same time, the LTE-A system has good backward compatibility . There are multiple Component Carriers (CCs) in the LTE-A system, and an LTE terminal can only work on a certain backward compatible CC, while an LTE-A terminal with strong capabilities can work on multiple CCs at the same time to transfer. That is, to realize LTE-A terminals transmit and receive data in multiple component carriers at the same time, so as to achieve the purpose of increasing bandwidth. This technology is called multi-carrier aggregation technology.

In the research of LTE R11 stage, on the basis of multi-carrier aggregation technology, new requirements are put forward for spectrum resource utilization, network energy saving, and interference suppression between cells. In order to achieve this goal, a new carrier type (New Carrier Type, NCT for short, usually referred to as a new carrier, for details, please refer to the public discussion paper in LTE R11) is proposed. With the help of carrier aggregation technology, the new carrier has a distinctive feature, that is, it does not need to consider backward compatibility during design, and more new technologies can be applied to it. For example, the current definition of a new carrier in LTE R11 is that it needs to be paired with at least one compatible carrier for operation (also known as carrier aggregation operation with a compatible carrier), and the cell reference signal of LTE R8 is not configured in the new carrier. -specific Reference Signals, referred to as CRS), to avoid serious CRS interference at the cell edge of adjacent cells, especially CRS interference between macro cells and micro cells in a heterogeneous network (HETerogeneous NETwork, HetNet) scenario. In the discussion of LTE R11, in order to further improve the use scenarios of the new carrier, a new carrier that operates independently is also proposed. At this time, the new carrier has the ability to independently access UEs and operate independently. Of course, it can also be paired or aggregated with other carriers.

At present, the new carrier is being standardized as a new carrier type. The following are some consensuses in the new carrier:

In the new carrier, a single-port CRS with a period of 5 milliseconds (5ms) is used to perform synchronous tracking (called 5msCRS in the text, or called synchronous tracking CRS). Obviously, this is different from the CRS in the existing system, and the supported ports The numbers vary.

In the new carrier, especially in the synchronous new carrier, it is currently discussing whether to configure and send PSS/SSS and 5msCRS. If the result of the discussion is not to configure PSS/SSS and 5msCRS.

The physical downlink control channel (Physical Downlink Control Channel, PDCCH) field is not configured in the new carrier, and the original PDCCH field may be used to transmit the PDSCH. PHICH and PCFICH are not configured in the new carrier.

According to the conclusion of the new carrier above, if the new carrier type is used in the COMP (CoordinatedMulti-Point, coordinated multi-point) scenario, the following problems need to be solved: Multiple transmission nodes (Transmission Point, TP) are proposed in COMP ) to serve a UE, and introduce quasi-co-location (QCL) signaling to solve the problem of time and frequency differences among multiple TPs. QCL signaling is to solve the problem that the synchronization timing of Rel10 cannot be applied in the COMP scenario. The essence is that when different TPs cooperate for the same UE, the channels from different TPs correspond to large scale properties (including timing error, timing spread, frequency shift, frequency spread ( frequencyspread), etc.), it is considered that under some COMP transmission methods (such as DPS, DPB, JT), the large-scale attributes of the CRS measurement corresponding to the serving cell can no longer be used to replace the COMP transmission (the transmission TP is not necessarily the serving cell), Therefore, for this situation, it is necessary to give which TP reference signals have the same large-scale properties as the DMRS corresponding to the current PDSCH transmission, that is, from the UE side, which CSI-RS (corresponding to the TP node) and the current transmission. The DMRS corresponding to the same channel is notified to the UE through signaling.

In the COMP scenario, if the TP uses a conventional carrier type carrier (called a compatible carrier), the above problems can be solved by introducing QCL signaling. However, through analysis, it is considered that when the new carrier type is used in the COMP scenario However, there are still the following problems that cannot be solved: QCL signaling can only solve the problem of time and frequency asynchrony, but cannot solve the problem of carrier type. In other words, it cannot specify the channel and /or signaling configuration, so that when multiple types of carriers serve it, the UE cannot timely determine whether the resources in the carrier are signaling or data, which leads to the failure of the UE to demodulate data.

Description of drawings

Fig. 1 is a schematic diagram of a method for generating carrier configuration information in the present invention.

Detailed ways

In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

Through analysis, it is considered that when NCT is used in the COMP scenario, the existing QCL signaling cannot complete the indication of channel and signaling configuration information in NCT, for example, it cannot indicate whether CRS is configured in NCT, or whether 5ms CRS is configured in NCT. Synchronous tracking cannot indicate whether there are channel configurations such as PDCCH, PHICH, and PCFICH. As a result, when the coordinated UE receives the data in the NCT, it cannot determine whether the information in the RE should be used as its own data demodulation or a common reference signal. The problem of demodulation performance degradation.

To solve this problem, the present invention proposes a signaling structure. One of the main purposes and functions of the signaling structure is that when the base station uses multiple carrier coordination or aggregation, or multiple TP coordination or aggregation for the UE, when multiple When there are different types of carriers or carrier channels in the carrier or multiple TPs, and the signaling configuration is different, use this signaling structure to notify the UE to meet the quasi-co-sited carrier or the reference signal in the carrier, such as meeting the synchronization requirements (including fine synchronization or synchronous tracking requirements) quasi-co-site, quasi-co-site to meet the CSI measurement, etc. Wherein, the signaling structure includes signaling identifying a carrier type or a channel in a carrier, and signaling configuration signaling. Among them, it is also necessary to increase the ability to meet quasi-co-site in the signaling structure, and the ability specifically includes: synchronization ability (sharing synchronization accuracy), and CSI measurement ability (sharing CSI measurement results). For example, it is described that the CSI measurement result is shared between multiple carriers, or the CSI measurement result of a certain carrier can be replaced by a certain carrier.

As shown in FIG. 1 , the method for generating carrier configuration information in the present invention includes: the network side device agrees with the user equipment (UE) on the signaling structure of the carrier configuration information and sends it to the UE; the signaling structure includes at least the following parameters One of: quasi-co-sited cell identification information, cell reference signal (CRS) port number or CRS configuration information, multimedia broadcast single frequency network (MBSFN) subframe configuration information, carrier type information, used for reference signal received power ( RSRP) measurement CSI-RS configuration information, channel state information reference signal (CSI-RS) configuration information for synchronous tracking, CSI-RS configuration information for CSI measurement, reference signal configuration information for synchronous tracking, used Demodulation Reference Signal (DMRS) configuration information for synchronous tracking. Wherein, when multiple types of carriers exist in the UE cooperating node or in the carrier or cell used by the UE, the signaling structure includes carrier type information.

The above signaling structure can be used for COMP or carrier aggregation.

Wherein, if the cell where the UE is located participates in cooperation or aggregation, the configuration of the signaling structure in this cell may be omitted. For example, if cell 1 is the cell where the UE is located, that is, the working cell, then the configuration information of cell 1 may be omitted.

The network side device configures the signaling structure in the cell handover signaling, cell reselection signaling or measurement signaling and sends the carrier configuration information configured in the above signaling structure to the UE. Specifically, the carrier configuration information is included in an existing RRC message as an information unit and sent to the UE, or a new RRC message is introduced to send the carrier configuration information to the UE. It can also be that the network side device sends the carrier configuration information to the UE through a dedicated radio resource control (RRC) message, or when the network side configures the cooperative node for the UE or there is a new carrier type in the carrier or cell used by the UE , sending the carrier configuration information to the UE through the carrier paired with the new carrier. This signaling structure can also be used in the signaling of cell handover, cell reselection, and measurement. When the UE performs cell handover, the base station configures the signaling for the UE so that the UE can perform measurement on the target cell. The signaling structure can also be sent in the cell as the content of the system broadcast message, for example, it can be selected to be sent in SIB3, SIB4 or SIB5.

The functions, uses and values of the parameters in the signaling structure are described in detail below.

The signaling structure is used to notify the UE of the carrier or the reference signal in the carrier that satisfies the quasi-co-site characteristic, wherein the signaling structure includes signaling that identifies the carrier type or the channel and/or signaling configuration signaling in the carrier, and the quasi-co-site The stations include: quasi-co-sites that meet the synchronization requirements, and quasi-co-sites that meet the CSI measurement. The quasi-co-site feature means that the setting operations between carriers or reference signals in carriers have the same effect or have the same preset standards. As a result, the setting operation includes at least one of the following: synchronization tracking, CSI measurement, cell handover, and cell reselection.

The identification information of the quasi-co-sited cell is used to identify whether quasi-co-sited is satisfied between the carrier or cell or transmission node serving the UE and another cell or carrier or transmission node. For example, the identified cells meet the quasi-co-site relationship, so that the UE can use the reference signals in the cells that meet the co-site relationship to achieve synchronous tracking between each other. For example, cell 2 and cell 1 meet the co-site relationship. At this time, the UE The CSI-RS in cell 1 can be used to perform synchronous tracking to the same effect as the CRS in cell 2 to perform synchronous tracking.

Use at least one of the following parameters to describe the identity information of the quasi-co-sited cell: cell physical identifier (ID), secondary cell index (SCellIndex), cell virtual ID, cell physical ID, carrier frequency, and serving cell index (ServCellIndex), the sequence index corresponding to the cell ID, and the configuration information of the reference signal in the cell. Among them, the configuration information of the reference signal in the cell can use the CSI-RS configuration information or configuration label of the cell, because the CSI-RS can be configured with different patterns for different cells, so the CSI-RS configuration information of different cells is different .

The identification information of the quasi-co-sited cells may simultaneously identify two or more cells or carriers or transmission nodes satisfying the quasi-co-sited cells. When the identification information of quasi-co-sited cells simultaneously identifies two or more cells or carriers or transmission nodes that meet the quasi-co-sited requirements, this parameter must be included in the signaling structure.

The number of CRS ports or the CRS configuration information is used to identify the number of CRS ports used in the cell or carrier or transmission node identified by the identification information of the quasi-co-sited cell. Through this parameter, the UE can determine the mapping pattern of the CRS in the cell or carrier or TP.

When the number of CRS ports or CRS configuration information is {0, 1, 2, 4}, 1, 2, and 4 correspond to port numbers of 1, 2, and 4; 0 indicates that no CRS is configured in the cell or carrier or indicates that the carrier The CRS configured in is 5 milliseconds. The CRS configuration information includes the way to realize the CRS configuration information through the number of CRS ports, and also includes the direct description of the CRS configuration in the carrier. For example, the CRS configuration information takes the value {0, 1}, where 0 means that there is no CRS configuration in the carrier, and 1 Indicates that 5msCRS is configured in the carrier. Alternatively, when the number of CRS ports or CRS configuration information is {0, 1}, 0 means no 5msCRS, and 1 means there is 5msCRS.

The MBSFN subframe configuration information is used to describe the MBSFN subframe configuration in the cell or carrier or transmission node identified by the identification information of the quasi-co-sited cell. Through this parameter, the UE can know the MBSFN subframe configuration information in the corresponding cell or carrier or TP. MBSFN subframe configuration information is represented by an MBSFN subframe configuration (MBSFN-SubframeConfig) information element.

The carrier type information refers to the cell or carrier or the carrier type used in the transmission node identified by the identification information of the quasi-co-sited cell, and helps the UE to know the channel and/or signaling configuration in the cell, carrier or transmission node . Therefore, the UE can determine the data and common signaling of the UE in the resource of the carrier. At the same time, the carrier type information is also used to describe the cell or carrier set in the quasi-co-sited cell or the carrier type used in the TP, and is also used to help the UE identify the data and common signaling of the UE in the carrier resource. The carrier type information includes the following types: compatible carrier type, new carrier type, synchronous new carrier type, non-synchronous new carrier type, and independent operation new carrier type. The carrier type information describes channel and/or signaling configuration information in the quasi-co-sited cell or carrier, and helps the UE know the channel and/or signaling configuration in the cell or carrier.

The carrier type information includes the following types: compatible carrier type, new carrier type, synchronous new carrier type, non-synchronous new carrier type, and independent new carrier type.

Channel and/or signaling configuration conditions include at least one of the following: whether to configure primary-secondary synchronization signaling (PSS/SSS); the time domain position of PSS/SSS; whether to configure CRS; whether to configure 5 ms CRS for synchronization tracking; whether to configure Time domain positions of PBCH and ePBCH; whether to configure PHICH; whether to configure PCFICH; whether to configure PDCCH; whether to configure ePBCH, ePHICH, and ePDCCH. If ePHICH and ePDCCH are configured, it is necessary to inform the resources occupied by these channels to facilitate the terminal to perform rate matching. Of course, the terminal can also be informed in the signaling whether to decode the system parameter information on the NCT to obtain relevant content. The above configurations can be described indirectly through the agreed carrier type information. For example, it is stipulated that CRS, 5msCRS, PHICH, PCFICH, and PDCCH are not configured in the new carrier type. At this time, for convenience, you can directly notify If the carrier type of the UE is the new carrier type, the UE can know that the channel and signaling configuration of the carrier is based on the new carrier type, otherwise, it needs to directly notify the UE of the configuration situation. In summary, the channel and/or signaling mainly includes configurations of various control channels and configurations of various reference signals.

The CSI-RS configuration information for RSRP measurement is used to describe the CSI-RS configuration for RSRP measurement in a cell or carrier meeting quasi-co-sited or transmission nodes, and help UE determine the CSI-RS for performing RSRP measurement. The configuration information may describe the CSI-RS resource, or may use the method of describing the CSI-RS index (label, referring to multiple sets of CSI-RS, the agreed number).

Aiming at the problems in the background technology, the present invention provides a special solution at the same time, as follows: When the base station configures the carrier for cooperative or aggregated operation for the UE or the cell or the TP has a carrier of an incompatible carrier type, the base station still follows the The channel and signaling configuration in the compatible carrier performs UE data mapping and transmission on the non-compatible carrier, and the UE performs data reception and analysis on the cell or carrier or TP configured for itself according to the channel and signaling in the compatible carrier. In this way, the base station also does not need signaling to inform the UE of the type information of the carrier selected for the UE, the channel, and the signaling configuration information. Obviously, if the carrier resource of the new carrier type is mapped to data according to the channel and signaling of the compatible carrier, resource waste will obviously exist.

At this time, the carrier type parameter in the above signaling structure is deleted, and the original signaling still needs to be sent, such as carrier or cell or TP configuration information or quasi-co-site information.

For example, there are no channels such as PCFICH, PHICH, and PDCCH in the new carrier. If the base station maps data according to compatible carriers, it still does not map UE data in the original PCFICH, PHICH, and PDCCH, which obviously wastes certain resources. For another example, there is no CRS configuration of R8 in the new carrier, and only CRS with or without 5ms period is configured for synchronization tracking. If the mapping is still carried out according to the situation of R8 CRS in the compatible carrier, the RE occupied by CRS is obviously wasted. However, this method simplifies the processing at the base station and UE side.

The following will be described in detail through specific embodiments.

Specific embodiment 1

When the coordinating node in COMP uses the new carrier type and compatible carrier type to serve the UE, it is further assumed that the new carrier type agrees not to use CRS, PDCCH, PHICH, PCFICH, continue to use PBCH, R8 PSS/SSS, and the base station sends The signaling structure includes:

Identification information of quasi-co-sited cells, number of CRS ports, MBSFN subframe configuration information, carrier type information, and reference signal configuration information for synchronous tracking. The specific signaling structure is as follows:

The signaling structure shows that cell 1 and cell 2 satisfy the quasi-co-site relationship, and the cells are described by using the cell physical ID and the CSI-RS index configured by the cell respectively. The configurations in cell 1 and cell 2 include CRS port, MBSFN subframe configuration, carrier type, synchronous tracking reference signal, synchronous tracking CSI-RS configuration, synchronous tracking DMRS configuration, CSI-RS configuration for RSRP measurement, CSI-RS configuration for CSI measurement. RS configuration. Among them, when there is a carrier with a compatible carrier type, the CRS port parameter is mandatory. For a new carrier type, if there is no synchronous tracking reference signal configuration information, the value of the CRS port is 0 to indicate the synchronous tracking reference information configuration. If there is synchronous tracking reference signal configuration information, the CRS port may not be configured. If there is an MBSFN subframe in the quasi-co-sited cell, the configuration information of the MBSFN subframe is mandatory. Synchronous tracking reference signal, synchronous tracking CSI-RS configuration, synchronous tracking DMRS configuration, these three configuration information for synchronous tracking can be configured according to the specific one used in the carrier, the carrier If there is no configuration in , you can delete the corresponding parameters. For the CSI-RS configuration parameter of RSRP measurement, if the carrier is designated to use CSI-RS to perform RSRP measurement, then configure this parameter accordingly, otherwise do not configure this parameter, because in most cases the existing R8CRS and 5msCRS can be used For RSRP measurement, CSI-RS is used to perform RSRP measurement in a few cases or under special regulations. The CSI-RS configuration parameter for CSI measurement is also configured according to specific scenarios and is an optional parameter. When multiple carriers of different carrier types are coordinated or aggregated for the UE, the carrier type parameter must be configured. If the carrier type parameter is not configured, the carrier can use a compatible carrier type by default.

If the UE works in cell 1, then according to this signaling structure, the UE can know that cell 1 and cell 2 satisfy the fine synchronization relationship, and the UE knows that cell 2 is a new carrier type through the carrier type information in cell 2, so when When the UE receives the data in the cell 2, it can know the channel and signaling configuration in the cell 2, so that the UE can know the RE in which its own data in the cell 2 is located.

This signaling structure can be directly used when the base station configures a coordinated cell or carrier or TP for the UE, and it can also be directly used when the base station selects a synchronous carrier for the UE or aggregated operation between cells or TPs. After the structure, the UE not only knows the coordinated cell or carrier or TP information, but also knows the signaling and channel configuration information in these cells or carrier or TP, which makes the UE work more convenient.

Specific embodiment 2

An illustration of adding relevant information in CSI-RS-ConfigNZP to form the signaling structure of the present invention is as follows:

The carrier type at this time identifies the cell or carrier or TP described by the parameter qcl-ScramblingIdentity-r11, and the cell or carrier or TP identified by the parameter scramblingIdentity-r11 in the signaling structure defaults to a compatible carrier type for the UE, so there is no Introduce carrier type. This signaling structure is suitable for the case where new carriers that are not independently operated participate in coordinated or aggregated operations. At this time, the cell identified by the parameter qcl-ScramblingIdentity-r11 adopts a certain type of new carrier that is not independently operated, and is specified by the parameter scramblingIdentity-r11 The identified cell uses a compatible carrier type by default. When the UE finds that the cell identified by the parameter scramblingIdentity-r11 has no parameter carrier type according to the signaling structure, the UE considers the compatible carrier type used by the cell.

Among them, the value of crs-PortsCount-r11 is increased by n0, indicating that the carrier identified by qcl-ScramblingIdentity-r11 is not configured with R8CRS, but is configured with 5msCRS.

The carrier type parameter is introduced so that it can be known whether a new carrier or a compatible carrier is used in a cell that meets the QCL relationship, so as to indirectly know the channel, signaling configuration, and mapping in the QCL cell, so that the UE can receive data in the QCL cell to avoid common channel, signaling.

Specific embodiment 3

An illustration of adding relevant information in CSI-RS-ConfigNZP to form the signaling structure of the present invention is as follows:

At this time, the cells in the signaling structure are respectively configured with carrier type parameters, the first carrier type parameter identifies the carrier type of the cell described by the parameter scramblingIdentity-r11, and the second carrier type parameter identifies the carrier type parameter by the parameter qcl-ScramblingIdentity-r11 Describes the carrier type of the cell.

If only the carrier type signaling cannot help the UE to know the channel and signaling configuration information in the carrier, the carrier type parameters at this time can be replaced by specific channel and signaling configuration parameters. For example, a possible replacement method is : Replace the carrier type parameter with the following channel and signaling configuration information: PCFICH configuration information, describing whether the carrier is configured with PCFICH; PHICH configuration information, describing whether the carrier is configured with PHICH; PDCCH configuration information, describing whether the carrier is configured with PDCCH; PSS/SSS configuration information, describing whether PSS/SSS is configured in the carrier; CRS configuration information, describing whether there is a CRS configured with R8 in the carrier; 5ms cycle CRS configuration information, describing the configuration of 5msCRS in the carrier (if configured, Including subframe offset information, bandwidth); PBCH configuration information, describing the configuration of PBCH in the carrier (if configuring a new PBCH, including the indication information of the new PBCH).

The carrier type parameter is introduced so that it can be known whether a new carrier or a compatible carrier is used in a cell that meets the QCL relationship, so as to indirectly know the channel, signaling configuration, and mapping in the QCL cell, so that the UE can receive data in the QCL cell to avoid common channel, signaling.

Specific embodiment 4

This embodiment is different from the above-mentioned real embodiment 1～3.

Assuming that the base station selects a carrier or cell or TP for coordinated or aggregated operation for the UE (the carrier is taken as an example below), and the base station knows that there are new carrier types among these carriers, and these new carrier types are not configured with PDCCH, PCFICH, PHICH And R8CRS, configured with 5ms period of CRS and PSS/SSS. Compatible carriers are configured with PDCCH, PCFICH, PHICH, R8CRS and PSS/SSS.

The base station still maps the data of the UE on the carrier of the new carrier type in a compatible carrier manner, for example, it needs to avoid the resources occupied by PDCCH, PCFICH, PHICH, R8CRS and PSS/SSS, and cannot be sent on the resources occupied by these channels and signaling UE data.

At this time, the carrier type parameter in the above signaling structure is deleted, and the original signaling still needs to be sent, such as carrier or cell or TP configuration information or quasi-co-site information.

At this time, the base station does not notify the UE of the type information of the carrier configured for the UE, and the UE still receives data on the carrier according to the type of the compatible carrier, avoiding resources occupied by the channel and signaling.
