Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and in particular, to an information transmission method, a terminal, a device, and a medium. Background Art

[0002] With the popularization of communication network systems in various industries and geographical regions, the network has become more dense, using more antennas, larger bandwidths, and more frequency bands, and needs to process services and applications with high-rate requirements. The energy consumption of the network system has increased accordingly, and new solutions need to be developed to improve network energy saving.

[0003] In related technologies, network energy saving can be achieved by reducing the Synchronization Signal / Physical Broadcast Channel block (or Synchronization Signal Block) SSB (Synchronization Signal and PBCH block) and / or the System Information Block SIB (System Information Block). Specifically, SSB and / or SIB can be transmitted only in the anchor cell, and the energy-saving cell does not transmit SSB and / or SIB. When the terminal UE (User Equipment) stays in the anchor cell, it can access the energy-saving cell based on the SSB and / or SIB transmitted by the anchor cell and perform data transmission in the energy-saving cell. That is, the UE can synchronize in the energy-saving cell by measuring the SSB and / or SIB in the anchor cell. However, regarding the synchronization error between the anchor cell and the energy-saving cell, related technologies only define the theoretical value of the synchronization error, which results in poor actual synchronization effect between the anchor cell and the energy-saving cell, or between the terminal and the energy-saving cell, and further leads to poor communication performance of the network system.

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] The terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of this application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are usually of the same category, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally means an "or" relationship between the associated objects before and after.

[0042] For the convenience of understanding, some content related to the embodiments of the present invention will be described as follows:

[0043] The energy consumption of the network system is increasing day by day, and new solutions need to be developed to improve network energy saving. In the related art, energy saving can be achieved by reducing SSB / SIB (this energy saving mode can also be called SSB / SIB-less), dynamically turning on / off cells, discontinuous transmission DTX (Discontinuous Transmission) / discontinuous reception DRX (Discontinuous Reception), etc.:

[0044] SSB / SIB-less: For multi-carrier or dual-connection scenarios, including an anchor cell (transmitting SSB and SIB) and an energy-saving cell (not transmitting SSB / SIB), the UE camps on the anchor cell, can access the energy-saving cell based on the SSB / SIB transmitted by the anchor cell, and perform data transmission in the energy-saving cell; for primary and secondary carrier synchronization, the UE can retrieve system information from another intra-band cell that transmits SSB and SIB1 and perform synchronization based on that cell.

[0045] Dynamic cell on / off: When the load is distributed among multiple cells and the load in each cell is relatively light, the network can consider converging the load to certain cells and dynamically turning off other cells to save energy consumption.

[0046] DTX / DRX: Allows the gNB to partially or fully turn off the transmission and reception of data services and reference signals (except for SSB transmission) during the DTX / DRX inactivity period of the cell.

[0047] In related technical solutions, considering the energy-saving scenario of carrier aggregation CA (Carrier Aggregation) for multi-carriers, the transmission of SSB and SIB will generate a large amount of base station energy consumption. To save base station energy consumption, some secondary cells (Scell) can be put into an energy-saving mode (e.g., achieved through technologies such as SSB / SIB-less cell, DTX / DRX, etc.). For the case of a cell with an energy-saving mode of SSB / SIB-less, the UE can perform synchronization in the SCell / energy-saving cell by measuring the SSB in the primary cell (PCell) / anchor cell. However, for this case, the prior art only defines the theoretical value of the synchronization error, and the network does not know the actual carrier synchronization error between the anchor cell and the energy-saving cell (that is, the actual primary and secondary carrier synchronization error between the PCell and the SCell). Therefore, it is also impossible to optimize the configuration of the anchor cell and / or the energy-saving cell according to the actual measurement error.

[0048] To address the above problems, an embodiment of the present invention proposes a network energy-saving optimization method, especially for the multi-carrier energy-saving scenario. The UE records and reports information such as the actual carrier synchronization error, the service performance of the energy-saving cell, and / or the measurement results between the anchor cell and the energy-saving cell, providing reference information for the network to optimize the cell configuration, enabling the network to understand and optimize the cell configuration in the energy-saving scenario.

[0049] In an embodiment of the present invention, an information transmission method, a terminal, a device, and a medium are proposed to solve the problem of poor communication performance of the existing network system.

[0050] See Figure 1 , Figure 1It is a flowchart of an information transmission method provided by an embodiment of the present invention, which is used for a first terminal, such as Figure 1 As shown, the method includes the following steps:

[0051] Step 101, obtain first information. Wherein, the first information includes the actual carrier synchronization error between the anchor cell and the energy-saving cell, and the anchor cell is the serving cell of the first terminal.

[0052] In the embodiment of the present invention, the first terminal pre-obtains the first information and sends it to the first network device. Wherein, for the first terminal to obtain the first information, it can be that the first terminal obtains the first information by receiving information sent by other devices, or it can be that the first terminal obtains the first information through the device's own information, or it can be that the first terminal obtains the first information through measurement means. The embodiment of the present invention does not limit this.

[0053] In the embodiment of the present invention, the above-mentioned energy-saving cell can be a cell that adopts energy-saving technology for SSB / SIB-less, that is to say, the energy-saving cell usually does not send SSB and / or SIB. The energy-saving cell can be called a non-anchor cell, or a cell in the energy-saving mode. While the anchor cell can send SSB and / or SIB, and the anchor cell can also be called a non-energy-saving cell, or a cell in the non-energy-saving mode. It can be understood that the energy-saving mode of each cell can be switched. The anchor cell can switch from the non-energy-saving mode to the energy-saving mode, and the energy-saving cell can also switch from the energy-saving mode to the non-energy-saving mode.

[0054] Wherein, the above-mentioned anchor cell and energy-saving cell can be of the same base station, or can be cross-base station. In the case of cross-base station, for example, the anchor cell and the energy-saving cell correspond to the first network device and the second network device respectively. When the first network device performs optimized configuration on the cell based on the first information, the first network device and the second network device can communicate the information related to the optimized configuration.

[0055] When the terminal hopes to access such an energy-saving cell, it can access the energy-saving cell based on the SSB and / or SIB transmitted by the anchor cell. The first terminal records and reports the first information to the network, and the network analyzes the problem based on the first information and optimizes and adjusts the carrier synchronization related configuration between the anchor cell and the energy-saving cell.

[0056] Optionally, in the embodiment of the present invention, the above-mentioned anchor cell can be the PCell where the first terminal camps, and the above-mentioned energy-saving cell can be the Scell that the first terminal hopes to access. The above-mentioned actual carrier synchronization error can be the actual master-slave carrier synchronization error between the PCell / anchor cell and the Scell / energy-saving cell.

[0057] Optionally, the first information includes at least one of the following:

[0058] The actual carrier synchronization error between the anchor cell and the energy-saving cell;

[0059] The identifier of the energy-saving cell;

[0060] The identifier of the anchor cell;

[0061] The service information of the first terminal;

[0062] The service information of the first terminal;

[0063] The minimized drive test (MDT) measurement result of the energy-saving cell;

[0064] The MDT measurement result of the anchor cell;

[0065] The capability information of the first terminal;

[0066] The location information of the first terminal.

[0067] In an embodiment of the present invention, the first information includes one or more of the following information:

[0068] The actual carrier synchronization error between the anchor cell and the energy-saving cell (SSB / SIB-less cell), for example, the actual synchronization error between the primary and secondary carriers;

[0069] Energy-saving cell ID(s), indicating the cell ID(s) where SSB / SIB is not transmitted and the UE performs random access and uplink (UL) / downlink (DL) data transmission; where there can be multiple energy-saving cells, and the actual carrier synchronization errors between the corresponding anchor cell and the energy-saving cell (SSB / SIB-less cell) can also be multiple;

[0070] Anchor cell ID, indicating the cell ID that represents a non-anchor cell (e.g., an energy-saving cell) to send SSB / SIB;

[0071] The service performance of the UE in the energy-saving cell, such as: bit rate, latency, traffic, etc.;

[0072] The service information of the UE, for example, the traffic of the UE, quality of experience (QoE), slice and other information;

[0073] The MDT measurement results of the energy-saving cell mainly include information such as the reference signal received power (RSRP), the reference signal received quality (RSRQ), and / or the signal to interference plus noise ratio (SINR);

[0074] The MDT measurement results of the anchor cell mainly include information such as RSRP, RSRQ, and / or SINR;

[0075] UE capability information, such as: whether it supports accessing the energy-saving cell (scellWithoutSSB), whether it supports energy-saving terminals (Network Energy Saving, NES-capable UE) or does not support energy-saving terminals (non-NES capable UE), etc.;

[0076] The location information of the UE.

[0077] In the embodiments of the present invention, the MDT (minimization of drive tests) technology automatically performs drive tests through commercial terminals, records measurement data, and reports it to the base station. The base station collects the drive test data and summarizes and reports it to the network management operation administration maintenance (OAM), realizing the automated acquisition and collection and summarization of data, reducing the workload of manual drive tests, and is an important means for wireless network optimization and network quality assessment.

[0078] In the embodiments of the present invention, the UE can record and report the actual carrier synchronization error between the anchor cell and the energy-saving cell by adopting the MDT process, and report the actual carrier synchronization error together with the MDT measurement results of the energy-saving cell's minimization of drive tests and / or the MDT measurement results of the anchor cell, which can further optimize the energy-saving configuration process.

[0079] Optionally, the obtaining of the first information includes:

[0080] Obtaining the actual carrier synchronization error through system frame number and frame timing deviation (SFTD) measurement.

[0081] In the embodiments of the present invention, for the case where the first information includes the actual carrier synchronization error between the anchor cell and the energy-saving cell, the terminal can specifically determine the actual carrier synchronization error by measuring the SFTD (SFN and frame timing difference).

[0082] The actual carrier synchronization error between the energy-saving cell and the anchor cell can be measured and recorded by SFTD. For an SSB / SIB-less energy-saving cell, since its SSB / SIB information is received by the UE from the anchor cell and then used by the UE to access the SSB / SIB-less energy-saving cell, and the energy-saving cell does not transmit SSB / SIB information, the anchor cell does not know the actual carrier synchronization error between it and the energy-saving cell. In this case, the system frame number (SFN) and the frame timing difference (SFTD) of the UE can be used to measure and help the network deduce the time difference of the SFN and the frame boundaries of the anchor cell and the energy-saving cell.

[0083] Step 102: Send the first information to the first network device.

[0084] In the embodiment of the present invention, the above-mentioned first terminal reports the first information to the first network device, and the first network device can perform problem analysis based on the first information and optimize and adjust the carrier synchronization related configurations of the anchor cell and the energy-saving cell. Specifically, it can analyze the synchronization between the anchor cell and the energy-saving cell, and then optimize and adjust the synchronization between the anchor cell and the energy-saving cell.

[0085] Optionally, the sending of the first information to the first network device includes at least one of the following:

[0086] Send the first information to the first network device when a preset trigger event is satisfied;

[0087] In response to a request message sent by the first network device, send the first information to the first network device.

[0088] Before the sending of the first information to the first network device in response to the request message sent by the first network device, the method further includes:

[0089] Send a first indication information to the first network device, where the first indication information is used to indicate that the first terminal stores the first information.

[0090] In the embodiment of the present invention, after the UE records / stores the first information, it can be reported in any of the following ways:

[0091] Triggered by an event, the UE actively reports to the network (the first network device);

[0092] The network sends a request message to the UE, requesting the UE to report relevant information (the first information);

[0093] The UE sends indication information to the network (indicating that relevant information that can be reported is stored on the UE side). After receiving the indication information, the network sends a request message to the UE, requesting the UE to report the relevant information.

[0094] Optionally, the triggering event includes at least one of the following:

[0095] A preset measurement event;

[0096] Receiving second indication information sent by the first network device, where the second indication information is used to indicate that the anchor cell will switch to an energy-saving mode.

[0097] In the embodiments of the present invention, the above triggering event may be a preset measurement event. For example, the A3 event: the service quality of the neighboring cell is higher than the service quality of the SpCell by a specified offset value; the A4 event: the signal quality of the neighboring cell is higher than a specified threshold value; the A5 event: the signal quality of the serving cell is lower than a specified threshold value, while the signal quality of the neighboring cell is higher than a specified threshold value. The above A3, A4, A5, etc. are only examples, and the embodiments of the present invention are not limited to these three measurement events, and may also be other measurement events in the related art.

[0098] In the embodiments of the present invention, in another optional triggering event, if the cell currently accessed by the terminal is in a non-energy-saving mode but is about to enter the energy-saving mode, "the UE receives an indication from the network that it is about to enter the NES mode" is introduced as a new triggering event, and the UE reports the measurement result, avoiding waste of measurement resources caused by the UE, especially the non-NES capable UE, being switched to other cells after the cell enters the energy-saving mode and the measurement result not being reported.

[0099] In the information transmission method of this embodiment, obtain first information; send the first information to a first network device; where the first information includes the actual carrier synchronization error between the anchor cell and the energy-saving cell, and the anchor cell is the resident cell of the first terminal. By sending the actual carrier synchronization error between the anchor cell and the energy-saving cell to the network, the terminal can assist the network in synchronizing and optimizing the anchor cell and the energy-saving cell, which can improve the network communication performance.

[0100] See Figure 2 , Figure 2 is a flowchart of another information transmission method provided by the embodiments of the present invention, for a first network device, such as Figure 2 shown, the method includes the following steps:

[0101] Step 201, receive the first information sent by the terminal.

[0102] In the embodiments of the present invention, the above terminal may be one terminal or multiple terminals. For example, it may includeFigure 1 terminals including the first terminal in the illustrated embodiment. Then, the above-mentioned Figure 1 all implementation manners in the illustrated method embodiment are applicable to Figure 2 the illustrated embodiment, and can achieve the same or similar beneficial effects. To avoid repeated description, this embodiment will not be elaborated further.

[0103] Optionally, the first information includes at least one of the following:

[0104] The actual synchronization error between the carrier frequencies of the anchor cell and the energy-saving cell;

[0105] The identifier of the energy-saving cell;

[0106] The identifier of the anchor cell;

[0107] The service performance of the terminal;

[0108] The minimized drive test (MDT) measurement result of the energy-saving cell;

[0109] The MDT measurement result of the anchor cell;

[0110] The capability information of the terminal;

[0111] The location information of the terminal.

[0112] For the above optional implementation manners, reference can be made to the relevant descriptions in the Figure 1 illustrated embodiment. To avoid repeated description, this embodiment will not be elaborated further.

[0113] Step 202: When the first information includes the actual synchronization error between the carrier frequencies of the anchor cell and the energy-saving cell, determine the configuration manner of at least one of the anchor cell and the energy-saving cell according to the actual synchronization error; wherein, the anchor cell is the cell where the terminal camps.

[0114] In the embodiment of the present invention, for the relevant descriptions of the first information, the anchor cell, the energy-saving cell, and the actual synchronization error between the carrier frequencies, reference can be made to the relevant descriptions in the Figure 1 illustrated embodiment. To avoid repeated description, this embodiment will not be elaborated further.

[0115] In the embodiment of the present invention, when the first network device receives the actual synchronization error between the carrier frequencies of the anchor cell and the energy-saving cell sent by the terminal, it can optimize the synchronization between the anchor cell and the energy-saving cell based on the actual synchronization error between the carrier frequencies of the anchor cell and the energy-saving cell.

[0116] Optionally, when the capability information of the terminal indicates that the terminal does not support energy saving and the anchor cell is about to enter the energy-saving mode, instruct the terminal to switch to a non-energy-saving cell or a non-energy-saving base station.

[0117] In the embodiments of the present invention, the situation where the terminal does not support energy saving may be that the terminal does not support scellWithoutSSB, or the terminal is a non-NES capable UE. When the anchor cell is about to enter the energy-saving mode (specifically, in the case of the second indication information sent by the first network device to the terminal), the first network device may instruct the terminal to switch to a non-energy-saving cell or a non-energy-saving base station. The above non-energy-saving cell may use another non-energy-saving cell corresponding to the first network device as the new anchor cell, and the above non-energy-saving base station may be a second network device other than the first network device.

[0118] In the embodiments of the present invention, for the situation where the currently accessed cell is about to enter the energy-saving mode, the network sends indication information to indicate to the UE that it is about to enter the energy-saving mode. After receiving the indication information sent by the network, the UE reports the UE measurement result. The UE measurement result includes at least one of the following: the identifier of the cell, UE capability information, MDT measurement result, UE service information. After the network receives the UE reported information:

[0119] If this UE is a non-NES capable UE, then switch this UE to another non-energy-saving cell / base station

[0120] If this UE is a NES-capable UE,

[0121] If the service requirements of this UE can still be met after entering the energy-saving mode, then send the energy-saving mode information to this UE, and this UE can continue to perform services in this cell / base station

[0122] If the service requirements of this UE cannot be met after entering the energy-saving mode, then switch this UE to other non-energy-saving cells / base stations.

[0123] Optionally, the configuration method for determining any one of the anchor cell and the energy-saving cell according to the actual synchronization error of the carrier includes:

[0124] When the actual synchronization error of the carrier does not meet the first preset threshold, adjust the configuration method of the energy-saving cell.

[0125] In the embodiments of the present invention, the fact that the actual carrier synchronization error does not meet the first preset threshold can be understood as the actual carrier synchronization error being greater than or equal to the first preset threshold. Then, the fact that the actual carrier synchronization error meets the first preset threshold can be understood as the actual carrier synchronization error being less than the first preset threshold; or, the fact that the actual carrier synchronization error does not meet the first preset threshold can be understood as the actual carrier synchronization error being greater than the first preset threshold. Then, the fact that the actual carrier synchronization error meets the first preset threshold can be understood as the actual carrier synchronization error being less than or equal to the first preset threshold.

[0126] When the actual carrier synchronization error meets the first preset threshold, the above-mentioned first network device may not make adjustments. When the actual carrier synchronization error does not meet the first preset threshold, it can be understood that the reported actual error is too large, and thus optimization is required. The specific optimization may be to adjust the configuration of the energy-saving cell.

[0127] In the embodiments of the present invention, the first preset threshold in the embodiments of the present invention may be agreed upon by the protocol, may be network-configured, or may be determined based on other methods. The embodiments of the present invention do not limit this.

[0128] Optionally, the first information sent by the receiving terminal includes:

[0129] Receiving the first carrier actual synchronization error between the first anchor cell and the first energy-saving cell sent by the first terminal;

[0130] Receiving the second carrier actual synchronization error between the first anchor cell and the second energy-saving cell sent by the second terminal;

[0131] The method for adjusting the configuration of the energy-saving cell when the actual carrier synchronization error does not meet the first preset threshold includes:

[0132] When the first carrier actual synchronization error does not meet the first preset threshold and the second carrier actual synchronization error meets the first preset threshold, instructing the first terminal to access the second energy-saving cell;

[0133] The first preset threshold is used to indicate the theoretical carrier synchronization error.

[0134] In the examples of the present invention, for the case of multiple energy-saving cells, by analyzing the first information reported by multiple UEs, it is possible to select to access another energy-saving cell with a smaller actual synchronization error between the primary and secondary carriers. The first network device instructs the first terminal to access the second energy-saving cell. Whether the first terminal will access the second energy-saving cell can be determined through negotiation between the first terminal and the first network device.

[0135] Optionally, when the actual synchronization error of the first carrier does not meet the first preset threshold and the actual synchronization error of the second carrier meets the first preset threshold, instructing the first terminal to access the second energy-saving cell includes:

[0136] When the actual synchronization error of the first carrier does not meet the first preset threshold, the actual synchronization error of the second carrier meets the first preset threshold, and the remaining capacity of the second energy-saving cell is greater than the second preset threshold, instruct the first terminal to access the second energy-saving cell;

[0137] The second preset threshold is used to indicate the radio resources and capacity occupied after the terminal accesses.

[0138] In the embodiments of the present invention, for the case of multiple energy-saving cells, by analyzing the first information reported by multiple UEs, it is possible to select to access another energy-saving cell with a smaller actual synchronization error between the primary and secondary carriers, but this situation only occurs when another energy-saving cell can accommodate more UEs.

[0139] Optionally, when the actual synchronization error of the carrier does not meet the first preset threshold, adjusting the configuration mode of the energy-saving cell includes:

[0140] When the actual synchronization error of the carrier does not meet the first preset threshold, trigger the energy-saving cell to enter the non-energy-saving mode.

[0141] In the embodiments of the present invention, when the actual synchronization error of the carrier does not meet the first preset threshold, it can be understood that the reported actual error is too large, and the energy-saving cell can be switched to the non-energy-saving mode, that is, the energy-saving cell no longer relies on the SSB and / or SIB sent by the anchor cell to implement the access of the UE, but sends the SSB and / or SIB by itself.

[0142] Optionally, the energy-saving cell is used to send at least one of the synchronization signal block SSB and the system information block SIB in the non-energy-saving mode to enable the terminal to access, and enter the energy-saving mode after the terminal accesses.

[0143] In the embodiments of the present invention, trigger the energy-saving cell to exit the energy-saving mode first, and send SSB / SIB. After the UE successfully accesses, then enter the energy-saving mode.

[0144] Exemplarily, the network is optimized according to the received first information. If the reported actual error is less than the value acceptable to the network, no adjustment is made; if the reported actual error is too large, the optimization adjustment method can be:
