Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
In the description that follows, the terms "first," "second," and the like are used for descriptive purposes only and are not intended to indicate or imply relative importance nor order to be construed.
First, an application scenario of the present disclosure will be explained. Due to the increasing tension of radio frequency, especially gold frequency below 1GHz with excellent transmission characteristics, an operator can upgrade to 4G/5G with higher spectrum efficiency on the original 2G/3G frequency, because the bandwidth of the 2G/3G frequency spectrum is narrow, the resources of low frequency band are very limited, the bandwidth actually owned by the operator is not an integral multiple of 5MHz (such as 4MHz, 6MHz, 7MHz, 8MHz, 9MHz, 11MHz, etc.), and these residual frequencies are often idle after the network upgrade, resulting in lower utilization rate of the spectrum resources. In addition, the coverage performance of the low frequency band below 1GHz is excellent, and 80% of site addresses can be saved compared with the 3.5GHz band, so the price of the frequency spectrum of the low frequency band is very expensive, and a large amount of capital waste is caused by the idle frequency spectrum.
Therefore, operators hope to use these residual bandwidths urgently, but the inventors of the present application found that if different system bandwidths are defined for different residual bandwidths in the standard, the complexity of the device is greatly increased (supporting a large number of bandwidth options), and further, the standard workload and the test workload are increased by multiple times, and the industry may be differentiated (different devices only support different partial bandwidth options).
In order to solve the above problem, the present disclosure provides a method, an apparatus, a storage medium, a terminal, and a network device for network access. A terminal receives a system message sent by network equipment according to random access resource configuration information of an overlapped aggregation carrier, wherein the overlapped aggregation carrier is formed by overlapping and aggregating a first carrier and a second carrier; determining a target carrier from the first carrier and the second carrier according to the system message; and accessing the network equipment through the target carrier according to the system message. Therefore, the existing system bandwidth can be utilized, and the idle spectrum resources are efficiently utilized in a mode of overlapping and aggregating the first carrier and the second carrier, so that the utilization rate of the spectrum resources is improved on the premise of low sensing and low transformation of the terminal.
The first carrier and the second carrier of the present disclosure may be carriers having a bandwidth that is an integer multiple of 5, such as 10MHz, and the overlapping aggregated carrier may be carriers having a bandwidth that is a non-integer multiple of 5, such as 16MHz, wherein a sum of the first bandwidth of the first carrier and the second bandwidth of the second carrier is greater than a bandwidth of the overlapping aggregated carrier.
Fig. 1 is a flowchart of a method for network access, which is applied to a terminal according to an embodiment of the present disclosure. As shown in fig. 1, the method may include:
s101, receiving a system message sent by the network equipment according to the random access resource configuration information of the overlapped aggregation carrier.
The overlapped aggregation carrier is formed by overlapping and aggregating a first carrier and a second carrier, and the random access resource configuration information may include a first random access resource corresponding to the first carrier, a second random access resource corresponding to the second carrier, a time domain transmission sequence corresponding to the first random access resource and the second random access resource, load information of the first carrier, load information of the second carrier, and the like. In addition, the first random access resource and the second random access resource may include a bandwidth of a signal allowed to be accessed, a time domain resource, and the like.
In this step, after acquiring the random access resource configuration information of the overlapped aggregated carrier, the network device may send a system message according to the random access resource configuration information, and the terminal may receive the system message sent by the network device. The system message may include random access resource configuration information for the overlapping aggregated carriers, a bandwidth of the overlapping aggregated carriers, a first bandwidth of the first carrier, and a second bandwidth of the second carrier.
And S102, determining a target carrier from the first carrier and the second carrier according to the system message.
In this step, after receiving the system message sent by the network device, the terminal may determine the target carrier from the first carrier and the second carrier according to the load information of the first carrier and the load information of the second carrier in the system message. In a possible implementation manner, a carrier corresponding to load information with the lowest load in the load information of the first carrier and the load information of the second carrier may be used as the target carrier. Therefore, the terminal can access the network equipment through the target carrier with lower load, and the success rate and the access efficiency of the terminal accessing the network equipment can be ensured.
S103, accessing the network equipment through the target carrier according to the system message.
In this step, after the terminal determines the target carrier according to the system message, the random access resource corresponding to the target carrier may be determined, where the random access resource corresponding to the target carrier is the first random access resource when the target carrier is the first carrier, and the random access resource corresponding to the target carrier is the second random access resource when the target carrier is the second carrier. Then, the terminal may determine the transmission time of the random access resource corresponding to the target carrier according to the time domain transmission sequence in the system message, and transmit the random access request on the target carrier according to the position and the transmission time of the random access resource corresponding to the target carrier. After receiving a random access request sent by a terminal, a network device may access the terminal according to the random access request.
By adopting the method, the terminal determines the target carrier from the first carrier and the second carrier according to the system message by receiving the system message sent by the network equipment according to the random access resource configuration information of the overlapped aggregation carrier, and accesses the network equipment through the target carrier according to the system message. Therefore, the existing system bandwidth can be utilized, and the idle spectrum resources are efficiently utilized in a mode of overlapping and aggregating the first carrier and the second carrier, so that the utilization rate of the spectrum resources is improved on the premise of low sensing and low transformation of the terminal.
Fig. 2 is a flowchart of a second method for network access, which is applied to a network device according to an embodiment of the present disclosure. As shown in fig. 2, the method may include:
s201, obtaining the random access resource configuration information of the overlapped aggregation carriers.
The overlapped aggregation carrier is formed by overlapping and aggregating a first carrier and a second carrier, and the random access resource configuration information may include a first random access resource corresponding to the first carrier, a second random access resource corresponding to the second carrier, a time domain transmission sequence corresponding to the first random access resource and the second random access resource, load information of the first carrier, load information of the second carrier, and the like. The first random access resource may include a bandwidth, a time domain resource, etc. of a signal that the first carrier allows access, and the second random access resource may include a bandwidth, a time domain resource, etc. of a signal that the second carrier allows access.
In this step, the network device may obtain a bandwidth and a time domain resource of a signal that the first carrier allows to access, a bandwidth and a time domain resource of a signal that the second carrier allows to access, a time domain transmission sequence, load information of the first carrier, and load information of the second carrier.
The load information of the first carrier may include a usage rate of a first random access resource on the first carrier, and the load information of the second carrier may include a usage rate of a second random access resource on the second carrier. In a possible implementation manner, the load information of the first carrier may be determined according to a success rate of sending the random access request on the first carrier, and the load information of the second carrier may be determined according to a success rate of sending the random access request on the second carrier. For example, after the success rate of sending the random access request on the first carrier is obtained, the number of the random access requests successfully sent on the first carrier can be calculated according to the success rate, and then the usage rate of the first random access resource on the first carrier, that is, the load information of the first carrier is obtained.
S202, sending a system message according to the random access resource configuration information.
The system message may include random access resource configuration information of the overlapping aggregated carriers, a bandwidth of the overlapping aggregated carriers, a first bandwidth of the first carrier, and a second bandwidth of the second carrier.
In this step, after the network device obtains the random access resource configuration information, the network device may send a system message according to the random access resource configuration information. Illustratively, the system messages may be sent on SSBs (synchronization signal/Physical Broadcast Channel Block) of overlapping aggregated carriers. After receiving the system message sent by the network device, the terminal may determine a target carrier from the first carrier and the second carrier according to the system message, and access the network device through the target carrier.
By adopting the method, the network equipment acquires the random access resource configuration information of the overlapped aggregation carrier and sends the system information according to the random access resource configuration information, so that the terminal determines the target carrier from the first carrier and the second carrier according to the system information and accesses the network equipment through the target carrier. Therefore, the existing system bandwidth can be utilized, and the idle spectrum resources are efficiently utilized in a mode of overlapping and aggregating the first carrier and the second carrier, so that the utilization rate of the spectrum resources is improved on the premise of low sensing and low transformation of the terminal.
Fig. 3 is a flowchart of a third method for network access provided by an embodiment of the present disclosure. As shown in fig. 3, the method may include:
s301, the network equipment acquires the load information of the first carrier and the load information of the second carrier.
The first carrier and the second carrier may be overlapped and aggregated to form an overlapped aggregated carrier, and a bandwidth of an overlapping portion of the first carrier and the second carrier is shared by the first carrier and the second carrier, so that the first carrier and the second carrier may collide when sharing the bandwidth of the overlapping portion.
In order to avoid collision between the bandwidth of the first random access resource corresponding to the first carrier and the bandwidth of the second random access resource corresponding to the second carrier, in one possible implementation manner, the bandwidth of the random access resource corresponding to one of the first carrier and the second carrier may be configured as a full bandwidth, and the bandwidth of the random access resource corresponding to the other carrier may be configured as a partial bandwidth. Illustratively, fig. 4 is a schematic diagram of overlapping carrier aggregation provided by an embodiment of the present disclosure, as shown in fig. 4, a bandwidth of a first carrier and a bandwidth of a second carrier are 10MHz, and a bandwidth of an overlapping aggregated carrier formed by overlapping and aggregating the first carrier and the second carrier is 16MHz, where a bandwidth of an overlapping portion is 4MHz, and the first carrier and the second carrier may share and use the bandwidth of the 4 MHz. In order to avoid collision between the bandwidth of the first random access resource corresponding to the first carrier and the bandwidth of the second random access resource corresponding to the second carrier, here, the bandwidth of the first random access resource may be configured to be 10MHz, and the bandwidth of the second random access resource may be configured to be 6 MHz.
It should be noted that, when the bandwidth of the random access resource corresponding to one of the first carrier and the second carrier is configured as the full bandwidth, and the bandwidth of the random access resource corresponding to the other carrier is configured as the partial bandwidth, the first carrier and the second carrier do not collide with each other any more, and the time domain resources and the time domain transmission sequences of the first carrier and the second carrier may not be considered.
In this step, the load information of the first carrier may include a usage rate of a first random access resource on the first carrier, and the load information of the second carrier may include a usage rate of a second random access resource on the second carrier. In a possible implementation manner, the load information of the first carrier may be determined according to a success rate of sending the random access request on the first carrier, and the load information of the second carrier may be determined according to a success rate of sending the random access request on the second carrier. For example, after the success rate of sending the random access request on the first carrier is obtained, the number of the random access requests successfully sent on the first carrier can be calculated according to the success rate, and then the usage rate of the first random access resource on the first carrier, that is, the load information of the first carrier is obtained.
S302, the network device determines a time domain sending sequence according to the load information of the first carrier and the load information of the second carrier.
In this step, the time domain transmission sequence may be determined according to the load information of the first carrier, the load information of the second carrier, and the length of the first time window. For example, the first time window may be divided into k transmission times according to the length of the first time window, the type of the signal to be transmitted, and the uplink and downlink timeslot allocation peer configured by the system, and then the transmission times corresponding to the first carrier and the second carrier are determined according to the load conditions of the first carrier and the second carrier. Here, the sum of the number of transmission instants corresponding to the first carrier and the number of transmission instants corresponding to the second carrier is less than or equal to k. For example, if it is determined that the first time window includes 6 transmission time instants, the load of the first carrier is 50%, and the load of the second carrier is 25%, it may be determined that the number of transmission time instants corresponding to the first carrier is 4, and the number of transmission time instants corresponding to the second carrier is 2. After determining the first number of transmission instants corresponding to the first carrier and the second number of transmission instants corresponding to the second carrier, the time domain transmission sequence may be determined according to the first number and the second number. Illustratively, it may be determined that the time-domain transmission sequence is 101101, the first transmission time instant is 1, which indicates that the first carrier is allowed to transmit signals using the shared network resource, and the second transmission time instant is 0, which indicates that the second carrier is allowed to transmit signals using the shared network resource.
It should be noted that, when determining the time-domain transmission sequence according to the first number and the second number, in order to avoid frequent switching of the receiver and the transmitter, the transmission time corresponding to the first carrier and the transmission time corresponding to the second carrier may be separately set, that is, the time-domain transmission sequence in the above example may be set to 111100; in order to reduce the average delay, the transmission time corresponding to the first carrier and the transmission time corresponding to the second carrier may be set alternately, that is, the time domain transmission sequence of the above example may be set to 101011. In this way, the time domain transmission sequence can be determined according to the load conditions of the first carrier and the second carrier, so that the resource allocation of the overlapped aggregation carriers is more flexible.
S303, the network equipment determines the frequency domain position information of the SSB.
In this step, a first bandwidth of the first carrier, a second bandwidth of the second carrier, and a preset subcarrier interval may be obtained, and the frequency domain location information of the SSB may be determined according to the first bandwidth, the second bandwidth, and the subcarrier interval. Here, the SSB bandwidth may be determined according to the subcarrier spacing, for example, the SSB bandwidth is 240 × subcarrier spacing, and when the subcarrier spacing is 15kHz, the SSB bandwidth may be calculated to be 3.6 MHz. Then, the frequency domain location information of the SSB may be determined according to the first bandwidth and the second bandwidth overlapping portion bandwidth, and in the case that the first bandwidth and the second bandwidth overlapping portion bandwidth are greater than the SSB bandwidth, the SSB may be determined to be located within the first bandwidth and the second bandwidth overlapping portion bandwidth; in the case where the first bandwidth and the second bandwidth overlap portion bandwidth are less than or equal to the SSB bandwidth, it may be determined that the SSB is located within the first carrier and the second carrier non-overlap portion bandwidth, respectively.
Illustratively, fig. 5 is a schematic diagram of a second overlapping carrier aggregation provided by the embodiment of the present disclosure, as shown in fig. 5, a bandwidth of a first carrier and a bandwidth of a second carrier are 10MHz, the first carrier and the second carrier overlap and aggregate to form an overlapping aggregated carrier with a bandwidth of 16MHz, a bandwidth of an overlapping portion of the first carrier and the second carrier is 4MHz, and in a case that a bandwidth of an SSB is 3.6MHz, a bandwidth of the overlapping portion of the first carrier and the second carrier is greater than a bandwidth of the SSB, and it may be determined that the SSB is located within the bandwidth of the overlapping portion of the first bandwidth and the second bandwidth (e.g., a black portion in fig. 5). Fig. 6 is a schematic diagram of a third overlapping carrier aggregation provided by the embodiment of the present disclosure, as shown in fig. 6, bandwidths of the first carrier and the second carrier are 5MHz, the first carrier and the second carrier are overlapped and aggregated to form an overlapping aggregated carrier with a bandwidth of 7MHz, a bandwidth of an overlapping portion of the first carrier and the second carrier is 3MHz, and in a case that a bandwidth of an SSB is 3.6MHz, a bandwidth of an overlapping portion of the first carrier and the second carrier is smaller than a bandwidth of the SSB, and it may be determined that the SSB is located within a bandwidth of a non-overlapping portion of the first carrier and the second carrier (e.g., a black portion in fig. 6), respectively.
It should be noted that, under the condition that the subcarrier spacing is not changed, the frequency domain position of the SSB is not changed, and therefore, the first resource position information and the second resource position information are not changed. Based on this, the network device may store the first resource location information and the second location information in advance, and may directly obtain the stored first resource location information and the stored second resource location information when it is determined that the subcarrier interval does not change, without repeating the step of obtaining the first resource location information and the second resource location information.
S304, the network device determines the first resource location information and the second resource location information according to the frequency domain location information of the SSB.
In this step, after determining the frequency domain location information of the SSB, the first resource location information and the second resource location information may be determined according to the frequency domain location information. For example, when the SSB is located within the overlapping bandwidth of the first carrier and the second carrier, it may be determined that the first resource location information and the second resource location information are also located within the overlapping bandwidth of the first carrier and the second carrier; when the SSB is located within the non-overlapping portion of the bandwidth of the first carrier and the second carrier, it may be determined that the first resource location information is located within the bandwidth of the first carrier and the second resource location information is located within the bandwidth of the second carrier.
S305, the network equipment sends the system message according to the random access resource configuration information.
The random access resource configuration information comprises load information of a first carrier, load information of a second carrier, a time domain sending sequence, first resource position information and second resource position information, wherein the first resource position information comprises position information of a first random access resource corresponding to the first carrier, and the second resource position information comprises position information of a second random access resource corresponding to the second carrier; the system message includes random access resource configuration information of the overlapping aggregated carriers, a bandwidth of the first carrier, and a bandwidth of the second carrier.
In this step, after the network device obtains the random access resource configuration information, the network device may send a system message according to the random access resource configuration information. Illustratively, the system message may be sent on the SSB of the overlapping aggregated carrier.
S306, the terminal takes the carrier corresponding to the load information with the lowest load in the load information of the first carrier and the load information of the second carrier in the system information sent by the network equipment as a target carrier.
S307, the terminal determines the position information of the random access resource corresponding to the target carrier from the first resource position information and the second resource position information in the system message sent by the network device.
In this step, after the terminal determines the target carrier from the first carrier and the second carrier, the location information of the random access resource corresponding to the target carrier may be determined. Exemplarily, when the target carrier is the first carrier, the location information of the random access resource corresponding to the target carrier is the first resource location information; and under the condition that the target carrier is the second carrier, the position information of the random access resource corresponding to the target carrier is the position information of the second resource.
S308, the terminal accesses the network equipment through the target carrier according to the position information and the time domain sending sequence of the random access resource corresponding to the target carrier.
In this step, after the terminal determines the target carrier and the location information of the random access resource corresponding to the target carrier, the time for sending the random access request may be determined according to the time domain sending sequence. For example, in the case that the target carrier is a first carrier and the time domain transmission sequence is 11010, the random access request may be transmitted on the first carrier according to the first resource location information at a first time; when the target carrier is the second carrier and the time domain transmission sequence is 11010, the random access request may be transmitted on the second carrier at a third time according to the second resource location information.
