Description

[0002] With the development of communication technology, the fifth generation of mobile communication technology has emerged. Among them, high reliability is one of the main characteristics of the fifth generation of mobile communication technology. In order to further improve the reliability of data transmission, the Third Generation Partnership Project defines time slot aggregation technology, which increases redundancy by sending the same data in n consecutive time slots to improve the reliability of data transmission.

[0003] In the prior art, there are several situations. In the first situation, the time slot aggregation parameter is not configured. At this time, the data is repeatedly transmitted. The packet loss rate for users at the edge of the cell is high, and the reliability requirement of the network cannot be met. In the second situation, the time slot aggregation parameter is configured to a fixed value. At this time, the data is repeatedly transmitted. Repeated transmission is unnecessary for users at the center of the cell. It is impossible to take into account both the reliability requirement of the service and the spectrum efficiency of the network at the same time, that is, the spectrum efficiency of the network cannot be guaranteed while meeting the reliability requirement of the service.

[0004] In view of this, there is an urgent need in the art to develop a new time slot aggregation method and device.

[0036] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as being limited to the examples set forth herein; on the contrary, these embodiments are provided so that the present disclosure will be more comprehensive and complete, and the concepts of the example embodiments are fully conveyed to those skilled in the art. The described features, structures, or characteristics may be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present disclosure. However, those skilled in the art will appreciate that the technical solutions of the present disclosure may be practiced while omitting one or more of the specific details, or other methods, components, devices, steps, etc. may be adopted. In other cases, known technical solutions are not shown or described in detail to avoid obscuring various aspects of the present disclosure.

[0037] The terms "a", "an", "the" and "said" are used in this specification to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express an open-ended inclusion and mean that additional elements / components / etc. may exist in addition to the listed elements / components / etc.; the terms "first" and "second" etc. are used only as labels and are not intended to limit the quantity of their objects.

[0038] In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings represent the same or similar parts, and their repeated descriptions will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities.

[0039] Figure 1 The schematic diagram of the process of the time slot aggregation method in the related art is shown as follows: Figure 1 As shown, step S110 is to configure the time slot aggregation parameter as a fixed value through network management, step S120 is the process of the terminal randomly accessing the network, and step S130 is the base station sending the manually configured time slot aggregation parameter through the wireless resource control layer. Specifically, after the terminal randomly accesses the network, if the time slot aggregation function is turned on, the base station will send the time slot set parameter through the wireless resource control layer. If the time slot aggregation function is not turned on, the base station will not send the aggregation parameter. At this time, the terminal defaults to a time slot aggregation parameter of 1.

[0040] Obviously, in the relevant technology, on the one hand, if the time slot aggregation function is not turned on, the reliability requirements of the service cannot be met; on the other hand, even if the time slot aggregation function is turned on, the time slot aggregation parameters are set to fixed values, which leads to the fact that the reliability requirements of the service and the spectrum efficiency of the network cannot be taken into account at the same time. Either the reliability requirements of the service are met but the spectrum efficiency of the network is reduced, or the frequency efficiency of the network is improved but the reliability requirements of the service cannot be met.

[0041] In view of the problems existing in the related art, the present disclosure proposes a time slot aggregation method. Figure 2 A schematic diagram of the process of the time slot aggregation method is shown, as shown in Figure 2 As shown, the time slot aggregation method includes at least the following steps:

[0042] Step S210: Acquire the transmit power of the demodulation reference signal corresponding to the access terminal, and detect the signal strength corresponding to the demodulation reference signal.

[0043] Step S220: Calculate the transmit power and signal strength to obtain the path loss, and determine the time slot aggregation parameter according to the path loss, so as to issue the time slot aggregation parameter.

[0044] In the method and apparatus provided in the exemplary embodiments of the present disclosure, the time slot aggregation parameter is determined according to the path loss. On the one hand, this avoids the situation in the prior art where the time slot aggregation parameter is a fixed value. On the other hand, different time slot aggregation parameters can be determined according to different path losses, thereby increasing the spectrum efficiency of the network while meeting the reliability requirements of the service.

[0045] The following describes in detail the various steps of the time slot aggregation method.

[0046] In step S210, the transmit power of a demodulation reference signal corresponding to the access terminal is acquired, and the signal strength corresponding to the demodulation reference signal is detected.

[0047] In the exemplary embodiments of the present disclosure, a base station refers to a device used to send and receive signals, and an access terminal refers to a terminal device that can establish communication with a base station through a contention-based random access method. Specifically, the access terminal can be a mobile phone, a computer, a tablet computer, or any other terminal device that needs to establish communication with a base station, and this exemplary embodiment does not specifically limit this.

[0048] When the access terminal establishes communication with the base station through a contention-based random access method, it needs to send random access signaling to the base station. In order to subsequently calculate the path loss, it is necessary to carry the transmission power corresponding to the demodulation reference signal that can measure the quality of the channel environment in the random access signaling. Then, when the base station obtains the random access signaling, it can obtain the transmission power of the demodulation reference signal carried in the random access signaling.

[0049] Signal strength refers to the signal strength of the demodulation reference signal detected by the base station. Based on this, the signal strength and the transmit power can be calculated to obtain the path loss.

[0050] For example, the base station obtains the transmit power b of the demodulation reference signal sent by the access terminal A, and the base station also detects that the signal strength corresponding to the demodulation reference signal is c.

[0051] In an optional embodiment, acquiring the transmit power of a demodulation reference signal corresponding to an access terminal includes: receiving random access signaling sent by the access terminal, and acquiring the transmit power of the demodulation reference signal carried in the random access signaling.

[0052] Among them, random access signaling refers to the signaling that the access terminal needs to send to the base station when establishing communication with the base station through a contention-based random access method, and the random access signaling carries the transmit power of the demodulation reference signal. Based on this, the base station can obtain the transmit power of the demodulation reference signal carried by the random access signaling after receiving the random access signaling.

[0053] For example, a random access signaling XX sent by an access terminal is received, and then the transmit power b of the demodulation reference signal carried in the random access signaling XX is acquired.

[0054] In this exemplary embodiment, after receiving the random access signaling, the transmit power of the demodulation reference signal carried in the random access signaling can be obtained, which lays a foundation for subsequently calculating the path loss using the transmit power.

[0055] In step S220, the transmit power and the signal strength are calculated to obtain the path loss, and the time slot aggregation parameter is determined according to the path loss, so as to issue the time slot aggregation parameter.

[0056] In the exemplary embodiments of the present disclosure, path loss refers to the loss generated by a signal during transmission. The larger the loss, the worse the channel environment is at this time, and the smaller the loss, the better the channel environment is at this time.

[0057] The path loss can specifically be the difference between the transmission power and the signal strength. According to the relationship between the path loss and the channel environment, the time slot aggregation parameter is further determined. After the base station determines the time slot aggregation parameter, the time slot aggregation parameter is sent to the access terminal to improve the reliability of data transmission.

[0058] For example, the transmission power is b, and the signal strength corresponding to the demodulation reference signal detected by the base station is c. Based on this, the path loss is bc. If the value of bc is less than 100 and greater than 90, the time slot aggregation parameter is determined to be 2, and then the time slot aggregation parameter 2 is sent to the access terminal.

[0059] In an alternative embodiment, Figure 3 FIG. 4 shows a flow chart of determining time slot aggregation parameters according to path loss in a time slot aggregation method. Figure 3 As shown, the method includes at least the following steps: In step S310, a channel environment threshold is obtained, and the path loss and the channel environment threshold are compared to obtain a channel environment comparison result.

[0060] The channel environment threshold refers to the limit value for measuring the quality of the channel environment. By comparing the path loss with the channel environment threshold, the quality of the channel environment can be determined. That is, the quality of the channel environment can be determined based on the channel environment comparison result.

[0061] For example, the channel environment threshold is 90 and the path loss is 88. Obviously, the channel environment comparison result obtained at this time is that the path loss is less than the channel environment threshold.

[0062] In step S320, a time slot aggregation parameter is determined according to the channel environment comparison result.

[0063] Among them, because the degree of the channel environment can be obtained according to the channel environment comparison result, the time slot aggregation parameter can be adaptively determined according to the channel environment comparison result.

[0064] For example, the channel environment threshold is 90 and the path loss is 88. Obviously, the channel environment comparison result obtained at this time is that the path loss is less than the channel environment threshold. At this time, the base station can decide not to enable the time slot aggregation function, and then determine the time slot aggregation parameter to be 1, and send the time slot aggregation parameter to the access terminal, or not send the time slot aggregation parameter. The terminal will assume that when the base station does not send the time slot aggregation parameter, the time slot aggregation parameter is 1.

[0065] In this exemplary embodiment, the time slot aggregation parameter is determined based on the channel environment comparison result. On the one hand, it avoids the situation in the prior art where the time slot aggregation parameter is a fixed value. On the other hand, different time slot aggregation parameters can be adaptively determined according to different channel environment comparison results, thereby meeting the service reliability requirements and improving the spectrum efficiency of the network.

[0066] In an optional embodiment, the channel environment threshold includes a first threshold; and according to the channel environment comparison result, the time slot aggregation parameter is determined, including: if the path loss is less than the first threshold, the time slot aggregation function is not enabled.

[0067] Among them, when the channel environment is good, there is no need to enable the time slot aggregation function. The first threshold refers to the limit of the path loss when the time slot aggregation function is not enabled, and the first threshold is usually no more than 154.

[0068] Based on this, when the path loss is less than the first threshold, it proves that the channel environment is good at this time and the base station does not need to turn on the time slot aggregation function. At this time, the base station can determine the time slot aggregation parameter to 1, or it may not determine the time slot aggregation parameter. When the base station does not determine the time slot aggregation parameter, the access terminal defaults to the time slot aggregation parameter of 1.

[0069] For example, the path loss is 85 and the first threshold is 95. Obviously, at this time, the path loss is less than the first threshold. At this time, the base station does not turn on the time slot aggregation function. When the base station determines not to turn on the time slot aggregation function, the time slot aggregation parameter can be determined as 1 and sent to the access terminal, or the time slot aggregation parameter can be not sent. When the access terminal does not receive the time slot aggregation parameter, the time slot aggregation parameter is automatically set to 1 by default.

[0070] In this exemplary embodiment, when the path loss is less than the first threshold, the time slot aggregation function is not enabled, thereby avoiding the need to enable the time slot aggregation function when the channel environment is good, thereby improving the spectrum efficiency of the network.

[0071] In an alternative embodiment, Figure 4 The schematic diagram of the process of determining the time slot aggregation parameter according to the channel environment comparison result in the time slot aggregation method is shown. The channel environment threshold also includes a second threshold, such as Figure 4 As shown, the method includes at least the following steps: In step S410, if the path loss is greater than or equal to the first threshold and the path loss is less than or equal to the second threshold, the time slot aggregation function is enabled.

[0072] Among them, the channel environment threshold also includes a second threshold. Specifically, the degree of the channel environment can be measured by comparing the second threshold with the path loss. It is worth noting that the second threshold cannot exceed 154, and the second threshold is greater than the first threshold. When the path loss is greater than or equal to the first threshold and the path loss is less than or equal to the second threshold, it proves that the channel environment needs to turn on the time slot aggregation function to meet the service reliability requirements.

[0073] For example, the first threshold is 90, the second threshold is 100, and the path loss is 98. Obviously, at this time, the path loss is greater than the first threshold and less than the second threshold, which proves that the channel environment needs to turn on the time slot aggregation function. Based on this, the base station turns on the time slot aggregation function.

[0074] In step S420, a time slot aggregation parameter is determined as a first parameter.

[0075] The first parameter refers to the value of the timeslot aggregation parameter determined when the path loss is greater than or equal to the first threshold and the path loss is less than or equal to the second threshold. Usually, the first parameter is 2.

[0076] In this exemplary embodiment, when the path loss is greater than or equal to the first threshold and the path loss is less than or equal to the second threshold, the time slot aggregation function is turned on and the time slot aggregation parameter is determined to be the first parameter. On the one hand, this avoids the situation in the prior art where the time slot aggregation parameter is set to a fixed value. On the other hand, the time slot aggregation parameter is determined based on the path loss, adapts to the quality of the channel environment, and improves the spectrum efficiency of the network while meeting the reliability requirements of the service.

[0077] In an alternative embodiment, Figure 5 The schematic diagram of the process of determining the time slot aggregation parameter according to the channel environment comparison result in the time slot aggregation method is shown. The channel environment threshold also includes a third threshold, such as Figure 5 As shown, the method includes at least the following steps: In step S510, if the path loss is greater than or equal to the second threshold and the path loss is less than or equal to the third threshold, the time slot aggregation function is enabled.

[0078] Among them, the channel environment threshold may also include a third threshold. Normally, the third threshold is less than 154, and the third threshold is greater than the second threshold. The quality of the channel environment is determined by comparing with the path loss. When the channel loss is greater than or equal to the second threshold, and the channel loss is less than or equal to the third threshold, it proves that the channel environment at this time is worse than when the channel loss is in the interval [first threshold, second threshold]. Therefore, it is necessary to enable the time slot aggregation function to meet the reliability requirements of the service.

[0079] For example, the second threshold is 100, the third threshold is 110, and the path loss is 103. Obviously, at this time, the path loss is greater than the second threshold, and the path loss is less than the third threshold. Therefore, the base station needs to turn on the time slot aggregation function.

[0080] In step S520, a time slot aggregation parameter is determined as a second parameter.

[0081] The second parameter is a time slot aggregation parameter determined when the path loss is greater than or equal to the second threshold and the path loss is less than or equal to the third threshold. Usually, the second parameter is determined to be 4.

[0082] For example, the second threshold is 100, the third threshold is 110, and the path loss is 103. Obviously, at this time, the path loss is greater than the second threshold, and the path loss is less than the third threshold. Therefore, the base station needs to turn on the time slot aggregation function, and the base station determines that the time slot aggregation parameter at this time is 4.

[0083] In this exemplary embodiment, when the path loss is greater than or equal to the second threshold and the path loss is less than or equal to the third threshold, the time slot aggregation function is turned on and the time slot aggregation parameter is determined to be the second parameter. On the one hand, this avoids the situation in the prior art where the time slot aggregation parameter is configured as a fixed value. On the other hand, the time slot aggregation parameter is determined based on the path loss, adapts to the quality of the channel environment, and improves the spectrum efficiency of the network while meeting the reliability requirements of the service.

[0084] In an alternative embodiment, Figure 6 FIG. 4 shows a flow chart of determining time slot aggregation parameters according to the channel environment comparison result in the time slot aggregation method. Figure 6 As shown, the method includes at least the following steps: In step S610, if the path loss is greater than a third threshold, the time slot aggregation function is enabled.

[0085] Among them, when the path loss is greater than the third threshold, it proves that the channel environment at this time is worse than when the path loss is in the interval [second threshold, third threshold]. Therefore, the base station will turn on the time slot aggregation function.

[0086] For example, the path loss is 125 and the third threshold is 120. Obviously, at this time, the path loss is greater than the third threshold, and the base station will turn on the time slot aggregation function.

[0087] In step S620, the time slot aggregation parameter is determined as the third parameter.

[0088] The third parameter refers to a time slot aggregation parameter determined by the base station when the path loss is greater than a third threshold. Typically, the third parameter is 8.

[0089] In this exemplary embodiment, when the path loss is greater than the third threshold, the time slot aggregation function is turned on, and the time slot aggregation parameter is determined to be the third parameter. On the one hand, it avoids the situation in the prior art that the time slot aggregation parameter is configured as a fixed value; on the other hand, the time slot aggregation parameter is determined based on the path loss, adapts to the quality of the channel environment, and improves the spectrum efficiency of the network while meeting the reliability requirements of the service.

[0090] In the method and apparatus provided in the exemplary embodiments of the present disclosure, the time slot aggregation parameter is determined according to the path loss. On the one hand, this avoids the situation in the prior art where the time slot aggregation parameter is a fixed value. On the other hand, different time slot aggregation parameters can be determined according to different path losses, thereby increasing the spectrum efficiency of the network while meeting the reliability requirements of the service.

[0091] In view of the problems existing in the related art, the present disclosure also proposes a time slot aggregation method. Figure 7 A schematic diagram of a time slot aggregation method is shown, which is applied to an access terminal, such as Figure 7 As shown, the time slot aggregation method includes at least the following steps:

[0092] Step S710: Send the transmit power corresponding to the demodulation reference signal.

[0093] Step S720. Receive a time slot aggregation parameter to transmit data based on the time slot aggregation parameter; wherein the time slot aggregation parameter is determined based on a path loss, the path loss is calculated based on the transmit power and the signal strength, and the signal strength corresponds to a demodulation reference signal.

[0094] In the method and apparatus provided in the exemplary embodiments of the present disclosure, the received time slot aggregation parameter is determined based on the path loss. On the one hand, this avoids the situation in the prior art where the time slot aggregation parameter is a fixed value. On the other hand, different time slot aggregation parameters are determined based on different path losses, which satisfies the reliability requirements of the service to a greater extent and improves the spectrum efficiency of the network.

[0095] In step S710, transmit power corresponding to a demodulation reference signal is sent.

[0096] In this exemplary embodiment, the transmit power corresponding to the demodulation reference signal can be used to measure the quality of the channel environment. Therefore, the access terminal needs to send the transmit power corresponding to the demodulation reference signal to the base station.

[0097] For example, the access terminal sends the transmission power b corresponding to the demodulation reference signal to the base station.

[0098] In an optional embodiment, sending the transmit power corresponding to the demodulation reference signal includes: sending random access signaling; wherein the random access signaling carries the transmit power of the demodulation reference signal.

[0099] The random access signaling refers to a signaling sent by the access terminal to the base station. When the base station receives the signaling, communication is established between the access terminal and the base station.

[0100] It is worth noting that the random access signaling also carries the transmit power of the demodulation reference signal, so that the transmit power can be subsequently sent to the base station to calculate the path loss.

[0101] For example, a random access signaling carrying a demodulation reference signal with a transmit power c is sent to the base station.

[0102] In this exemplary embodiment, the access terminal carries the transmit power of the demodulation reference signal in the random access signaling sent, which helps the subsequent base station calculate the path loss according to the transmit power and adaptively determine the time slot aggregation parameter according to the path loss.

[0103] In step S720, a time slot aggregation parameter is received to transmit data based on the time slot aggregation parameter; wherein the time slot aggregation parameter is determined according to a path loss, the path loss is calculated based on the transmission power and the signal strength, and the signal strength corresponds to a demodulation reference signal.

[0104] In this exemplary embodiment, after the base station determines the time slot aggregation parameter, it sends the time slot aggregation parameter to the access terminal, so that the terminal transmits data based on the time slot aggregation parameter.

[0105] For example, if the received time slot aggregation parameter is 2, the access terminal sends the same data in two consecutive extension slots of the same edge element to meet the reliability requirement of the service.

[0106] In the method and apparatus provided in the exemplary embodiments of the present disclosure, the received time slot aggregation parameter is determined based on the path loss. On the one hand, this avoids the situation in the prior art where the time slot aggregation parameter is a fixed value. On the other hand, different time slot aggregation parameters are determined based on different path losses, which satisfies the reliability requirements of the service to a greater extent and improves the spectrum efficiency of the network.

[0107] The time slot aggregation method in the embodiment of the present disclosure is described in detail below in conjunction with an application scenario.

[0108] For a base station, all access terminals within the coverage area of ​​the base station can send transmit power corresponding to the demodulation reference signal to the base station. Assume that there are three access terminals in the area covered by the base station, namely access terminal 1, access terminal 2 and access terminal 3, among which access terminal 1 is closest to the base station, the distance between access terminal 2 and the base station is greater than the distance between access terminal 1 and the base station, and access terminal 3 is farthest from the base station.

[0109] Based on this, the base station can obtain the transmit power a of the demodulation reference signal sent by access terminal 1, the base station can also obtain the transmit power b of the demodulation reference signal sent by access terminal 2, and the base station can also obtain the transmit power c of the demodulation reference signal sent by access terminal 3. After the base station detects the signal strength corresponding to the demodulation reference signal, it can calculate the path loss A, path loss B and path loss C respectively with the transmit power a, transmit power b and transmit power c.

[0110] Since the path loss A is less than the first threshold, the base station does not turn on the time slot aggregation function. Since the path loss B is greater than the first threshold and less than the second threshold, the base station determines the time slot aggregation parameter to 2. Since the path loss C is greater than the third threshold, the base station determines the timing aggregation parameter to 8.

[0111] In this application scenario, on the one hand, it avoids the situation in the prior art where the time slot aggregation parameter is a fixed value; on the other hand, different time slot aggregation parameters can be determined according to different path losses, thereby increasing the spectrum efficiency of the network while meeting the reliability requirements of the service.
