The embodiment of the application provides an information transmission method, which is used for avoiding the problem that when beam information is transmitted among base stations along with the expansion of a network, the scene change of a cell and the addition of an automatic neighboring cell, the transmission position and the number information of beams in a neighboring cell relation need to be manually configured, so that the measurement of a terminal is abnormal, and the perception of a user is influenced.
The method and the device are based on the same application concept, and because the principles of solving the problems of the method and the device are similar, the implementation of the device and the method can be mutually referred, and repeated parts are not repeated.
For example, the applicable system may be a global system for mobile communications (GSM) system, a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) General Packet Radio Service (GPRS) system, a long term evolution (L TE) system, a L TE Frequency Division Duplex (FDD) system, a L TE Time Division Duplex (TDD), a universal mobile system (universal mobile telecommunications system, UMTS), a universal internet Access (WiMAX) system, a WiMAX 5G system, and the like, including various microwave NR systems, WiMAX 5G systems, and UMTS systems.
In a different system, the name of the terminal device may also be different, for example, in a 5G system, the terminal device may be called a User Equipment (UE), the wireless terminal device may communicate with one or more core networks via a RAN, and the wireless terminal device may be a mobile terminal device such as a mobile phone (or a "cellular" phone) and a computer with a mobile terminal device, for example, a portable, pocket, hand-held, computer-included or vehicle-mounted mobile device that exchanges voice and/or data with a wireless access network.
The network device according to the embodiment of the present application may be a base station, which may include multiple cells, and depending on a specific application, the base station may also be referred to as an access point, or may refer to a device in an access network that communicates with a wireless terminal device through one or more sectors on an air interface, or may be named otherwise, the network device may be configured to convert a received air frame and an Internet Protocol (IP) packet into each other as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network, and the network device may also coordinate attribute management of the air interface, for example, the network device according to the embodiment of the present application may be a network device (base transceiver station, BTS) in a global system for mobile communications (GSM) or a code division multiple access (code division multiple access) network, or a CDMA) in a home evolved node B (cellular) network, a base station (WCDMA) or a home evolved node B-B network (node B) in an embodiment, or a home evolved node B-evolution network (node B) network, or a wireless network, a wireless.
Through the configuration of the indexes and the number of the beam transmissions, the terminal can more accurately measure the signals of the adjacent cells, therefore, the base station needs to know the information of the indexes and the number of the beam transmissions of the adjacent cells when configuring the measurement for the terminal, and X is defined in the existing 38.423 protocolNThe establishment process and the configuration update of the NG-RAN, the X2 establishment process and the configuration update process of the ENDC are defined in the 36.423 protocol, wherein the frequency point, the subcarrier interval and the SMTC of the serving cell can be carried, and beam information is not transmitted.
The information of the network initial neighboring cell relation can be manually configured through planning, but when the capacity of the network is expanded, the cell scene is changed, and the automatic neighboring cell is added, the information of the beam sending index and the number of the related neighboring cell relation need to be manually configured through the management station, so the workload is very large, and the manual operation is easy to make mistakes. Resulting in abnormal terminal measurement and affecting user perception.
Therefore, the present application provides a method for information transmission, and the following describes in detail various embodiments of the present application with reference to the drawings of the specification. It should be noted that the display sequence of the embodiment of the present application only represents the sequence of the embodiment, and does not represent the merits of the technical solutions provided by the embodiments.
Embodiment one, the configuration of the beam information ssb-ToMeasure.
In the embodiment of the present application, if the number of beams is 7 and the beam indexes are the first 7, that is, 0 to 6, in the beam information configured in the cell of the 3.5G frequency band, the configuration of the specific beam information is as follows:

Figure BDA0001951989080000121
where 11111110 indicates that the beam index is the first 7 beams.
And in the second embodiment, beam information is transmitted.
Passing pair X between source base station and target base stationNInterface establishment request (X)NSETUP REQUEST) and XNInterface setup request response (X)NSETUP RESPONSE), serving Cell Information element (IE Served Cell Information NR) and neighbor Cell Information (neighbor Cell Information NR) in NG-RAN NODE CONFIGURATION UPDATE (NG-RAN NODE CONFIGURATION UPDATE) and NG-RAN NODE CONFIGURATION UPDATE RESPONSE (NG-RAN NODE CONFIGURATION UPDATE access L EDGE) messages, acquiring beam Information of neighbor cells and updating the beam Information into a neighbor relation table.
The beam Information added in the IE Served Cell Information NR and neighbor Information NR is a Cell-level beam rather than a frequency point level beam, because the Cell-level beam can flexibly configure the index and number of beams according to the scenes of different cells, if the added beam Information is frequency point-level beam Information, the same frequency point requires the same index and number of beams, and the flexible configuration of the beam Information cannot be performed for different scenes of different cells of the same frequency point, which is not favorable for the practical application of the network.
In addition, base stations can communicate with each other by XNThe interface may transmit the beam information, and may transmit the beam information through the core network, and may also transmit the beam information through the X2 interface (see embodiment four)NThe interface transmits beam information as described in detail with reference to fig. 1, and the flow is as follows.
Step 201: operation Management (OM) module in a base station triggers XNThe establishment or configuration updating process of the interface is that when OM detects that at least one cell in a base station gNB is activated, X is triggeredNEstablishing process, or triggering configuration updating process when cell parameter is modified;
step 202, the High layer (High L evel, H L) of the base station generates corresponding Information, specifically, H L obtains all the Cell related Information needing to be transmitted to the target base station from the Cell related table or the adjacent Cell related table, including the serving Cell Information NR, the adjacent Cell Information NR and other Information needing to be transmitted, and generates XNInterface establishment request (X)NSETUP REQUEST) message or NG-RAN NODE CONFIGURATION UPDATE (NG-RAN NODE CONFIGURATION UPDATE) message. The Cell range includes all activated cells and cells configured with neighboring Cell relations at the local end, and the serving Cell Information element (IE Served Cell Information NR) and/or the neighboring Cell Information element (IE neighbor Cell Information NR) carry the number and index of beam Information beams;
step 203: the home base station (source base station) passes the message through XNThe port sends to the opposite terminal base station (target base station), wherein the message is XNA SETUP REQUEST message or an NG-RAN NODE CONFIGURATION UPDATE message;
step 204: the opposite terminal base station processes the received message, mainly to XNAnalyzing the SETUP REQUEST message or NG-RAN NODE CONFIGURATION UPDATE message to obtain cell related information; updating the number and index of the adjacent cell wave beams and other cell related parameters in the adjacent cell relation table; if the opposite-end base station has a neighboring cell of a certain cell, updating related data of a neighboring cell relation table, and storing the cell information without the neighboring cell by the base station through a special database for subsequent automatic neighboring cell adding function;
step 205, the opposite end base station completes the processing and sends corresponding Information to the original end base station, specifically, H L of the opposite end base station obtains all the Cell related Information which needs to be returned to the original end base station from the Cell related table and the adjacent Cell related table of the local station, the Cell related Information comprises Information in IE Served Cell Information NR and neighbor Cell Information NR, the number and index of wave beams and other Information which needs to be transmitted, and generates XNA SETUP RESPONSE message or an NG-RAN NODECONFIGURATION UPDATE ACKNOW L EDGE message, wherein the cell range comprises all activated cells and cells configured with the neighbor relation at the local terminal, and the base station at the opposite terminal can also be in XNThe interface message carries beam information;
step 206: the original end base station processes the received message, namely the original end base station processes XNThe method comprises the steps that a SETUP RESPONSE message or an NG-RAN NODE CONFIGURATION UPDATE ACKNOW L EDGE message is analyzed to obtain cell related information (carrying beam information), the number and index of adjacent cell beams in an adjacent cell relation table and other cell related parameters are updated, if an original base station has an adjacent cell of a certain cell, the related data of the adjacent cell relation table is updated, and for the cell information without the adjacent cell, the base station has a special database for storage and is used for a subsequent automatic adjacent cell adding function;
step 207: xNSetup complete or configuration update complete.
In the third embodiment, the base station configures the connection state measurement information for the terminal, referring to fig. 2, and the specific implementation steps are as follows.
Step 301: firstly, UE initiates an access/service request/switch-in/reestablishment/re-occupation Resume process; when the base station needs to configure the DRB resource for the terminal and trigger the RRC reconfiguration message, the base station needs to configure the connection state measurement information for the terminal at this time. The base station at the local terminal executes the initial access/switch-in/reestablishment/re-occupation process initiated by the UE, and the transmitted message in the process can carry beam information;
step 302, H L of the base station at the home terminal performs measurement configuration preparation according to the cell and frequency point information in the neighboring cell relation table, namely, determines the measurement configuration information which needs to be sent to the UE, wherein the measurement configuration information comprises beam information, namely the number and index of beams;
step 303: the base station of the local terminal judges whether the wave beam information configuration between the adjacent regions of the same frequency point is the same, if the wave beam information configuration between the adjacent regions of the same frequency point is the same, the step 304 is executed;
if the wave beam information configuration between adjacent regions of the same frequency point is different, entering 305;
the following explains, by way of example, whether the beam information configurations between adjacent cells of the same frequency point are the same in the home base station:
a base station a (gnba) has a cell (Cella), a frequency point a, which has two pilot frequency points, a frequency point b and a frequency point c, and the cell has 10 neighboring cells, wherein 5 neighboring cells have the same frequency point as the frequency point a, 3 neighboring cells have the same frequency point as the frequency point b, and 2 neighboring cells have the same frequency point as the frequency point c, and then the following judgment should be made:
judging whether the configuration is the same with the wave beam information of the Cella and the 5 adjacent regions which are the same with the frequency point a;
whether the beam information configuration is the same or not needs to be judged among 3 adjacent cells which are the same as the frequency point b;
whether the beam information configuration is the same or not needs to be judged among 2 adjacent cells which are the same as the frequency point c;
step 304: selecting the same beam information to configure to the UE in the configuration message;
step 305: selecting a collection of beam information between different adjacent zones to configure the collection of the beam information to the UE in a configuration message;
for example, on the premise of the example in step 303, if the beam information configuration is different between 3 neighboring cells that are the same as the frequency point b, the processing is as follows:
when the adjacent cell 1 beam is configured to be '00001110', the adjacent cell 2 beam is configured to be '10000000', and the adjacent cell 3 beam is configured to be '11110000', the beam information ssb-ToMeasure configuration configured at the frequency point b should be 11111110;
step 306: and the terminal reports the measurement report and carries out the subsequent process.
In the fourth embodiment, the beam information is transmitted between the base stations through the X2 interface, and the configuration of the connection state measurement information for the terminal is specifically implemented as follows:
at present, under the architecture of NSA, a 4G base station may configure an NR neighboring Cell, and trigger addition of a Secondary base station (Secondary gdnodeb, SgNB) according to measurement of a B1 Event (B-type measurement refers to an inter-system measurement Event, and a B1 Event refers to a measurement Event reported when a different system neighboring Cell is higher than a certain threshold, that is, Event B1), because a measurement test of B1 is an NR Cell, it is necessary to configure an NR measurement frequency point for a terminal in a 36.331 protocol, and Information of beams needs to be configured at the same time, that is, Information of a measured CONFIGURATION structure (one structural body in the protocol, which indicates measurement CONFIGURATION for the terminal) in an RRC reconfiguration message is added with Information of a corresponding frequency point, that is, the number and an index of beams, and at the same time, in a 36.423 protocol, if an EN-DC-X2 SETUP REQUEST and an EN-DC-X2 SETUP RESPONSE, a RESPONSE-CONFIGURATION message, that is added with optional Information of beams, that a ue-DC-X2 SETUP REQUEST and an optional beam can be added in an optional context, and an optional Information of a RESPONSE message, that is added with an optional Information of a beacon-UPDATE message.
Reference may be made to embodiment three and fig. 2 for a specific process of configuring beam information when configuring an NR measurement frequency point for a terminal in the 36.331 protocol, where a difference is that, in step 301, it needs to be determined whether a terminal capability supports EN-DC dual connection, a supported scenario will be subjected to subsequent measurement configuration, and a scenario not supported is only configured with L TE-related frequency points;
fig. 1 is a flow chart of beam information transmission by beam information added by corresponding IEs in EN-DC X2SETUP REQUEST (EN-DC X2SETUP REQUEST) and EN-DC X2SETUP REQUEST RESPONSE (EN-DC X2SETUP RESPONSE), EN-DC CONFIGURATION UPDATE (EN-DC CONFIGURATION UPDATE) and EN-DC CONFIGURATION UPDATE RESPONSE (CONFIGURATION UPDATE access L EDGE) messages in 36.423 protocol, except that this scenario can be applied to the following two scenarios:
in a first scenario, when the NR base station triggers an EN-DC X2SETUP REQUEST and an EN-DC CONFIGURATION UPDATE message to need to carry beam information of a serving cell and an adjacent cell, L the TE base station stores the beam information of the cell in the message and replies an EN-DC X2SETUP RESPONSE and an EN-DC CONFIGURATION UPDATE ack L EDGE message, but the message does not contain beam information because no concept related to beams is implemented for the L TE base station.
In the second scenario, when the NR base station receives the EN-DC X2SETUP REQUEST and the EN-DC CONFIGURATION UPDATE messages, it is not necessary to store the beam information of the cell in the message (because the message does not carry the beam information), and the returned EN-DC X2SETUP RESPONSE and EN-DC CONFIGURATION UPDATE access L EDGE messages need to carry the beam information of the serving cell and the neighboring cell.
By the information transmission method provided by the embodiment, the transmission of the beam information between the base stations in the 5G system can be realized, a large amount of manual operation is reduced, the correctness of network data is ensured, and meanwhile, the base stations are more flexible in measurement configuration of the terminal, and the user perception in the network is ensured.
