[0064] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0065] The following will specifically describe the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems through embodiments and in conjunction with the accompanying drawings. The following embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0066] In addition, the technical solutions described in the embodiments of the present application can be arbitrarily combined without conflict.

[0067] An embodiment of the present application provides a communication method, which is applied to a base station. Figure 1 A schematic diagram of a communication method provided in an embodiment of the present application Figure 1 .like Figure 1 As shown, in the embodiment of the present application, the communication method applied to the base station mainly includes the following steps:

[0068] S101. Broadcast energy efficiency information and / or energy efficiency penalty factor of at least one cell via a system message; wherein the energy efficiency penalty factor of each cell is negatively correlated with the cell energy efficiency.

[0069] In an embodiment of the present application, the base station may broadcast energy efficiency information and / or energy efficiency penalty factor of at least one cell through a system message; wherein the energy efficiency penalty factor of each cell is negatively correlated with the cell energy efficiency.

[0070] It should be noted that in the embodiments of the present application, the energy efficiency information and / or energy efficiency penalty factor of a cell may be the energy efficiency information and / or energy efficiency penalty factor of the base station to which the cell belongs. Based on this, the energy efficiency information and / or energy efficiency penalty factor of all cells under the same base station may be the same. Of course, the energy efficiency of each cell may also be independently evaluated and the energy efficiency information and / or energy efficiency penalty factor determined, which is not limited in the embodiments of the present application.

[0071] In an embodiment of the present application, the energy efficiency information of each cell includes at least one of the following:

[0072] Energy efficiency value of the community during the historical period;

[0073] Physical Resource Block (PRB) utilization and / or number of connected users of the cell during the historical period;

[0074] The current RF power and / or the average RF power over a historical period;

[0075] RF static power consumption.

[0076] It should be noted that, in the embodiment of the present application, the historical period can be a period of time before the current moment, for example, 30 seconds before the current moment. The specific length of the historical period can be set according to actual needs and application scenarios, and the embodiment of the present application does not limit it.

[0077] It should be noted that, in the embodiment of the present application, the energy efficiency value of a cell in a historical period is the ratio of the total uplink and downlink traffic of the cell in the historical period to the total energy consumption, where the total energy consumption is the product of the average power and the duration of the historical period.

[0078] It should be noted that in the embodiments of the present application, the RF power refers to the input power of the active antenna system (AAU) or the remote radio unit (RRU). The RF power of a base station is the sum of the powers of all AAUs or RRUs under the base station.

[0079] It should be noted that, in the embodiments of the present application, the radio frequency static power consumption refers to the radio frequency power when the load is zero.

[0080] It should be noted that in the embodiments of the present application, the energy efficiency information of each cell may include one or more of the above items. Of course, the above items are only exemplary optional information items, and the energy efficiency of the cell can also be described from other dimensions, that is, the energy efficiency information of the cell can also include other information that can represent the energy efficiency of the cell, which is not limited in the embodiments of the present application.

[0081] In the embodiment of the present application, the energy efficiency penalty factor of each cell is used to increase the residency threshold of low energy efficiency cells when performing the S criterion judgment for cell selection.

[0082] It should be noted that, in the embodiments of the present application, the energy efficiency penalty factor of each cell is negatively correlated with the cell energy efficiency, that is, the higher the cell energy efficiency, the smaller the energy efficiency penalty factor, and the lower the cell energy efficiency, the larger the energy efficiency penalty factor. Exemplarily, the value of the energy efficiency penalty factor can be an integer from 1 to 8, which is determined by the cell energy efficiency in the historical period. The lower the energy efficiency, the larger the value of the energy efficiency penalty factor. As described above, the energy efficiency information of the cell can be the energy efficiency information of the base station to which it belongs, that is, the base station energy efficiency is equivalent to the cell energy efficiency. In this case, the energy efficiency penalty factor of the cell is the energy efficiency penalty factor of the base station, which is negatively correlated with the base station energy efficiency. Of course, the energy efficiency of each cell can also be evaluated independently to determine the energy efficiency penalty factor, which is not limited in the embodiments of the present application.

[0083] In an embodiment of the present application, the base station may perform the following steps: when the energy-saving function is not turned on, or when the energy-saving function is turned on and the first cell does not meet the sleep condition, perform energy efficiency evaluation on the first cell to determine the energy efficiency information and / or energy efficiency penalty factor of the first cell; wherein the first cell is any cell of at least one cell.

[0084] It can be understood that in an embodiment of the present application, the base station can determine the energy efficiency information and / or energy efficiency penalty factor of the first cell when the energy-saving function is not turned on, for example, shallow sleep (or carrier shutdown), deep sleep, extreme sleep, or when the energy-saving function is turned on but the first cell does not meet the sleep conditions, and further broadcast it through a system message. Otherwise, it may be prohibited to determine the energy efficiency information and / or energy efficiency penalty factor of the first cell.

[0085] In an embodiment of the present application, the base station may also perform the following steps: when the energy-saving function is turned on and the first cell reaches the sleep condition, the energy efficiency information of the first cell is configured to a default value and / or the energy efficiency penalty factor of the first cell is configured to a maximum value or a specific value, and / or, an indication information that the first cell reaches the sleep condition is broadcast through a system message.

[0086] It can be understood that in an embodiment of the present application, if the energy-saving function has been turned on and the first cell reaches the sleep condition, it means that the first cell may be about to enter the sleep state. Based on this, the energy efficiency information of the first cell is directly configured as mentioned above, and / or the indication information that the first cell reaches the sleep condition is broadcast through a system message. In this way, the possibility of the terminal staying in the first cell can be reduced, so that the first cell can go into sleep smoothly.

[0087] In an embodiment of the present application, the base station may further perform the following steps to determine whether the first cell meets the sleep condition: when the energy-saving function is turned on, continuously monitor the sleep decision parameters of the first cell; when the sleep decision parameters meet the sleep threshold, determine that the first cell meets the sleep condition; wherein the sleep decision parameters include at least PRB utilization and / or the number of radio resource control (RRC) connections.

[0088] It is understood that in an embodiment of the present application, when the energy-saving function is enabled, the base station may continuously monitor the sleep decision parameter of the first cell and compare it with the sleep threshold to determine whether the sleep condition is met. The sleep decision parameter may include PRB utilization and / or the number of RRC connections, and of course, may also include other information characterizing the state of the first cell, which is not limited in the embodiment of the present application.

[0089] It should be noted that in the embodiment of the present application, the base station may also enable the first cell to enter a sleep state after the first cell reaches the sleep condition and the sleep decision parameter continues to meet the sleep threshold within a preset time period to save energy consumption.

[0090] In an embodiment of the present application, the base station may further perform the following steps: when the first cell reaches a sleep condition, perform unified access control (UAC) and broadcast the access restriction parameters of the first cell through a system message; wherein the access restriction parameters include at least an access identifier and / or an access category.

[0091] It can be understood that in the embodiments of the present application, in order to ensure special terminal / service needs, the UAC function can be used. When the first cell reaches the sleep condition, the two parameters of access identity (Access Identity) and access category (Access Category) are broadcast through system messages to restrict access to only some terminals. For example, except for paging, emergency affairs, security affairs, and public affairs, other access categories are prohibited.

[0092] The following is an illustrative description of the process of cell dormancy and information broadcasting in combination with the above content.

[0093] Figure 2This is a flow chart of an exemplary cell dormancy and information broadcasting provided in an embodiment of the present application. Figure 2 As shown, in the embodiment of the present application, the following steps are mainly involved:

[0094] S201. Evaluate the energy efficiency of a cell and broadcast energy efficiency information and / or energy efficiency penalty factors via system messages.

[0095] S202, turning on the energy saving function;

[0096] S203, determine whether the PRB utilization rate and the number of RRC connections meet the dormancy threshold; if the judgment result is yes, continue to step S204, otherwise, return to step S201;

[0097] S204: The cell reaches a dormant condition, and the energy efficiency information of the cell is configured as a default value and / or the energy efficiency penalty factor is configured as a maximum value or a specific value;

[0098] S205. Configure access restriction parameters for the cell and broadcast them via system messages.

[0099] S206: After the cell reaches the dormancy condition, it is determined whether the dormancy threshold is continuously met within the preset time period; if the determination result is yes, proceed to step S207; otherwise, return to step S203;

[0100] S207: The cell enters a dormant state.

[0101] An embodiment of the present application provides a communication method, which is applied to a terminal. Figure 3 A schematic diagram of a communication method provided in an embodiment of the present application Figure 2 .like Figure 3 As shown, in the embodiment of the present application, the communication method applied to the terminal mainly includes the following steps:

[0102] S301: Receive energy efficiency information and / or energy efficiency penalty factor of at least one cell broadcast through a system message; wherein the energy efficiency penalty factor of each cell is negatively correlated with the cell energy efficiency.

[0103] In an embodiment of the present application, as described in the above-mentioned communication method applied to the base station side, the base station can broadcast the energy efficiency information and / or energy efficiency penalty factor of at least one cell through a system message, and accordingly, the terminal can receive the energy efficiency information and / or energy efficiency penalty factor of at least one cell broadcast through the system message; wherein the energy efficiency penalty factor of each cell is negatively correlated with the cell energy efficiency.

[0104] It should be noted that in an embodiment of the present application, each base station can broadcast the energy efficiency information and / or energy efficiency penalty factor of the cell through a system message, and the terminal can receive the energy efficiency information and / or energy efficiency penalty factor of the cell broadcast by different base stations through system messages.

[0105] In an embodiment of the present application, the energy efficiency information of each cell includes at least one of the following:

[0106] Energy efficiency value of the community during the historical period;

[0107] PRB utilization and / or number of connected users in the cell during the historical period;

[0108] The current RF power and / or the average RF power over a historical period;

[0109] RF static power consumption.

[0110] It should be noted that, in the embodiments of the present application, the relevant explanations of the energy efficiency information and the energy efficiency penalty factor are detailed in the communication method on the above-mentioned base station side, which will not be repeated here.

[0111] In an embodiment of the present application, the terminal may further perform the following steps: during cell reselection and / or cell selection, based on energy efficiency information and / or energy efficiency penalty factor of at least one cell, determine a target cell from at least one cell and access the target cell.

[0112] It should be noted that, in the embodiments of the present application, the energy efficiency information and / or energy efficiency penalty factor of the cell can be applied to scenarios such as the cell reselection process of a terminal in an idle state or an inactive state, without specific limitation.

[0113] It is understandable that in the embodiments of the present application, the energy efficiency information and / or energy efficiency penalty factor of the cell can be used as reference information when the terminal performs cell reselection and / or cell selection to select a cell with appropriate energy efficiency as the target cell.

[0114] In an embodiment of the present application, the terminal determines a target cell from at least one cell based on energy efficiency information of at least one cell, including: determining a cell that meets the S criterion from at least one cell; and selecting a cell based on the energy efficiency information of the cell from the cells that meet the S criterion to determine the target cell.

[0115] It can be understood that in the embodiment of the present application, the terminal can determine the target cell according to the energy efficiency of the cell in the cell that meets the S criterion. Exemplarily, the cell selection can be performed in the following order: give priority to the cell with higher energy efficiency value, then select the cell with medium PRB utilization rate and / or number of connected users (that is, between two thresholds), and then select the cell with lower RF power at the current moment and / or average RF power in the historical period. That is, if a field is missing in the energy efficiency information of some cells, the field can be skipped and the next field can be compared in the above order to select the cell. Exemplarily, the RF static power consumption can be set as a required field. If the above fields are all missing, the cell with lower RF static power consumption is selected. The specific selection rules can be set according to actual needs and application scenarios, and are not limited in the embodiments of the present application.

[0116] In an embodiment of the present application, the terminal determines a target cell from at least one cell based on the energy efficiency penalty factor of at least one cell, including: for each cell, using the energy efficiency penalty factor of the cell as a decision parameter of the S criterion to perform an S criterion decision; wherein the energy efficiency penalty factor of each cell is used to change the cell's residence threshold and is positively correlated with the cell's residence threshold; and performing cell selection based on the S criterion decision result of each cell to determine the target cell.

[0117] For example, in an embodiment of the present application, for any cell, the energy efficiency penalty factor of the cell is used as a decision parameter of the S criterion to perform S criterion decision, including calculating the cell selection reception level values ​​Srxlev and Squal. The specific formula is as follows:

[0118] Srxlev=Q rxlevmeas -(Q rxlevmin + Q rxlevminoffset + Q eeoffset )-P compensation -Q offsettemp (1)

[0119] Squal= Q qualmeas -(Q qualmin + Q qualminoffset )- Q offsettemp (2)

[0120] Among them, Q eeoffset is the energy efficiency penalty factor of the cell, Q rxlevmeas is the receiving level value of the cell measured by the current terminal, Q rxlevmin is the minimum access level required to access the cell, Q qualmeas Q is the cell access quality measured by the current terminal, qualmin is the minimum access quality of the access cell, P compensation= MAX(PEMAX-PUMAX, 0), PEMAX is the maximum uplink transmit power available for the terminal configured in the cell, PUMAX is the maximum transmit power of the terminal, Q rxlevminoffset is the minimum access level bias parameter, Q qualminoffset is the minimum access quality bias parameter, Q offsettemp It is a temporary compensation parameter.

[0121] It should be noted that in the embodiments of the present application, the above-mentioned method of selecting cells based on the energy efficiency information and / or energy efficiency penalty factor of the cell is only an exemplary optional method. Of course, other strategies can also be set for cell selection according to actual needs and application scenarios, and the embodiments of the present application are not limited thereto.

[0122] In an embodiment of the present application, the terminal may further perform the following steps: receiving access restriction parameters of the first cell broadcast through a system message; before initiating access to the first cell, judging whether access to the first cell is supported based on the access restriction parameters; wherein the first cell is any cell of at least one cell; the access restriction parameters include at least an access identifier and / or an access category.

[0123] It will be appreciated that in the embodiments of the present application, corresponding to the above-mentioned communication method applied to the base station, the terminal may also receive access restriction parameters of a cell, for example, a first cell, broadcast via a system message, to thereby determine whether access to the first cell is supported. The access restriction parameters include at least an access identifier and / or an access category. For detailed explanations of the related information, please refer to the above-mentioned communication method applied to the base station and will not be repeated here.

[0124] It can be understood that based on the above-mentioned communication method applied to base stations and terminals, in the embodiments of the present application, on the one hand, energy efficiency considerations are increased to guide terminals to reside in high-efficiency cells, increase energy-saving opportunities in low-efficiency cells, and are more flexible than the method of manually configuring capacity layers and coverage layers; on the other hand, when the cell reaches the sleep condition, the UAC function is used to control the terminal access category, thereby avoiding secondary migration of users, improving sleep opportunities, and ensuring special business needs.
