Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
With the development of 5G technology, the application of 5G is more and more common. The 5G adopts a broadband mode to define frequency bands, forms a few global unified frequency bands, and greatly reduces the complexity of the terminal (mobile phone) for supporting global roaming. The maximum bandwidth of 5G is increased from 20MHz to the maximum support of 100MHz on the C-band, and the maximum support of 400MHz on the millimeter wave is equivalent to the road width, so that the downloading or uploading speed is greatly improved. In addition, the 5G adopts a more advanced symbol shaping technology, such as Filter-OFDM, so that the overhead of a frequency spectrum edge guard band is reduced, and compared with the 4G, the transmission bandwidth is obviously improved under the same nominal bandwidth. The use of multiple antennas brings spatial multiplexing gain, and can greatly improve capacity. However, the number of multiplexing layers that can be supported for a particular terminal is limited by the number of receive antennas. The number of receiving antennas of a standard terminal (mobile phone) is two, so that the maximum number of multiplexing layers can be supported to be two. Terminals using 4-receive antennas will become the mainstream in the future. The 5G NR doubles the number of the standard receiving antennas, and can greatly increase the downlink rate compared with the 2 receiving terminal and the 4 receiving terminal. A Supplemental Uplink (SUL) may be used in a wireless system, a cell configured with the SUL may be provided with a cell suitability criterion, a wireless transmit/receive unit (WTRU) may receive a page, the page with an indication of the carrier in which some or all of the initial access was initiated (e.g., SUL or Regular Uplink (RUL)), the WTRU performing responsive paging may provide beamformed (e.g., explicit) beam information for the paging message on the non-beamformed SUL, the SUL-equipped WTRU may be provided with a Handover (HO) procedure (e.g., carrier selection, configuration process, HO failure, etc.), the WTRU may request a change of the configured UL, the WTRU may perform (e.g., autonomously) a handover to a different (e.g., configured) uplink (e.g., when one or more conditions are met (e.g., conditional handover)), semi-persistent scheduling (SPS) resources/configurations may be relocated from a first UL to a second UL. In the current 3GPP5G NR Release 15 version, it is defined that a terminal may initiate uplink random access on a SUL frequency band (supplemental uplink) to increase the success rate of uplink random access of the terminal. This means that the terminal can initiate uplink random access in both the SUL band and the UL (uplink) band.
Through research, the current 3GPP protocol proposes a method for selecting a frequency band, that is, a terminal selects an uplink carrier by itself, and a network additionally carries a Reference Signal Receiving Power (RSRP) threshold in a system message, where the RSRP is a key parameter that can represent the strength of a wireless Signal in an LTE network, and is an average value of Signal powers received on all REs (resource elements) carrying reference signals in a certain symbol. The accessed frequency band is selected by comparing the RSRP value measured on the downlink carrier wave of the service area with the RSRP threshold value. However, the scheme is that the terminal is decided to access the selected frequency band uplink depending on the RSRP value, and when interference occurs, the selection of the frequency band is affected.
In order to solve the problems in the prior art, this embodiment provides a method for 5G NR uplink access, where in the process of selecting a frequency band, an accessed frequency band is selected by combining a radio signal strength parameter value and a frequency band interval, so that when the frequency band is accessed, a judgment is made without independently depending on the radio signal strength parameter value. In specific implementation, in this embodiment, a radio signal strength parameter value of a downlink frequency band of a service area is first obtained, a frequency band interval corresponding to the radio signal strength parameter value is determined according to the radio signal strength parameter value, and since each frequency band interval has a preset frequency band corresponding to the preset frequency band interval, a corresponding frequency band can be selected for uplink access according to the frequency band interval.
For example, when a terminal needs to be accessed to a cell in which a user is located in an uplink manner, a radio signal intensity parameter value of a downlink frequency band of the cell in which the user is located is first acquired, a frequency band interval corresponding to the acquired radio signal intensity parameter value is determined according to the acquired radio signal intensity parameter value, a correspondence between the radio signal intensity parameter value and the frequency band interval is preset, and after the frequency band interval is determined, a frequency band corresponding to the frequency band interval is selected according to the correspondence between the preset frequency band interval and the frequency band to access the terminal in the uplink manner.
Exemplary method
The method for 5G NR uplink access in this embodiment may be applied to a terminal device, such as a smart phone, a tablet computer, and a notebook computer, where the terminal device may initiate uplink random access in a supplemental uplink frequency band or an uplink frequency band. In specific implementation, as shown in fig. 1, the method for 5G NR uplink access in this embodiment includes the following steps:
step S100, obtaining a wireless signal strength parameter value of a downlink frequency band of a service area.
In specific implementation, since the frequency band for uplink access of the terminal is selected in this embodiment, the terminal device is required to measure the radio signal strength parameter value of the downlink frequency band of the service area first, and actually the measured value is the average value of the received signal powers on all REs (resource elements) carrying reference signals in a certain symbol, and the measured radio signal strength parameter value can reflect the radio signal strength of the service area, so that the frequency band for uplink access can be selected subsequently according to the radio signal strength. For example, if a user needs to perform uplink access to a terminal device in a cell where the user is located, the user needs to first obtain a radio signal strength parameter value of a downlink frequency band in the cell where the user is located, so as to reflect the radio signal strength of the cell where the user is located.
And S200, determining a frequency band interval corresponding to the wireless signal strength parameter value according to the wireless signal strength parameter value.
In this embodiment, after the wireless signal strength parameter value of the downlink frequency band of the service area is obtained, the frequency band interval corresponding to the wireless signal strength parameter value can be determined according to the wireless signal strength parameter value. Since the correspondence between the wireless signal strength parameter value and the frequency band interval is preset in this embodiment, the corresponding frequency band interval can be determined after the wireless signal strength parameter value is obtained.
In one implementation, as shown in fig. 2, the step S200 includes the following steps:
s201, comparing the wireless signal strength parameter value with a preset first threshold and a preset second threshold respectively to obtain a comparison result, wherein the first threshold is larger than the second threshold.
S202, determining a frequency range interval corresponding to the wireless signal strength parameter value according to the comparison result.
In specific implementation, after the wireless signal strength parameter value is obtained, the wireless signal strength parameter value is compared with a preset first threshold and a preset second threshold to obtain a comparison result, and a corresponding frequency band interval is selected according to the comparison result. When the sizes of the first threshold and the second threshold are preset, the first threshold is larger than the second threshold. Specifically, when the radio signal strength parameter value is greater than the first threshold, it is determined that a frequency band interval corresponding to the radio signal strength parameter value is a first interval, where a frequency band corresponding to the first interval is an uplink. That is to say, when the acquired radio signal strength parameter value is greater than the first threshold, the corresponding frequency band interval is determined to be the first interval according to the preset corresponding relationship, and the frequency band corresponding to the first interval is the uplink. Therefore, when the wireless signal strength parameter value is larger than the first threshold value, the uplink frequency band is selected for uplink access. For example, when a user performs uplink access to a terminal device in a cell, when it is detected that a wireless signal strength parameter value in a current cell is greater than a preset first threshold, it is determined that a first interval corresponds to the wireless signal strength parameter value, which indicates that a current wireless signal environment is good or interference is small, and therefore a frequency band corresponding to the first interval is an uplink.
And when the measurement result is smaller than the second threshold value, determining that the frequency band interval corresponding to the wireless signal strength parameter value is a second interval, wherein the frequency band corresponding to the second interval is a supplementary uplink. Specifically, in this embodiment, the measurement of the wireless signal strength parameter value at every preset time interval may be implemented by a preset timer, that is, when the obtained wireless signal strength parameter value is smaller than the second threshold, the timer is started to time, and the time for timing may be preset by the user. When the timer is overtime, the wireless signal intensity parameter value of the downlink frequency band of the service area is measured again to obtain a measurement result, if the measurement result is smaller than a second threshold value, the service area environment is poor or the interference is large, the frequency band interval corresponding to the wireless signal intensity parameter value is determined to be a second interval, and the frequency band corresponding to the second interval is a supplementary uplink, so that the supplementary uplink frequency band is selected for uplink access, and the success rate of random access when the environment is poor or the interference is large is favorably improved. For example, when a user performs uplink access to a terminal device in a cell, when it is detected that a wireless signal strength parameter value in a current cell is smaller than a preset second threshold and is continuously smaller than the second threshold for a certain time, it is determined that the wireless signal strength parameter value corresponds to a second interval, which indicates that a current wireless signal environment is poor or interference is large, and in order to improve a success rate of random access, a frequency band corresponding to the second interval is determined to be a supplementary uplink.
And when the wireless signal strength parameter value is smaller than a first threshold and larger than a second threshold, acquiring service state information, selecting uplink access if data or voice service exists in the service state information, and selecting supplementary uplink access if the data or voice service does not exist in the service state information. That is, when the wireless signal strength parameter value is not in the first interval and not in the second interval, the frequency band access is selected according to the traffic state information. Specifically, if the wireless signal strength parameter value is smaller than the first threshold and larger than the second threshold, and there is data or voice service in the service status information, the uplink access is selected. And if the wireless signal strength parameter value is smaller than the first threshold and larger than the second threshold and no data or voice service exists in the service state information, selecting to supplement uplink access. In addition, when no data or voice service exists in the service state information, the uplink is selected to be supplemented for uplink access, so that resources of the uplink can be saved, and the uplink can be allocated to a terminal with data or voice service in other service state information, which is beneficial to improving the utilization rate of air interface resources. For example, when a user performs uplink access to a terminal device in a cell, when it is detected that a radio signal strength parameter value in a current cell is smaller than a first threshold and larger than a second threshold, it is impossible to select a corresponding frequency band for access by determining a corresponding frequency band interval. At this time, according to whether a data or voice service exists in the service state information of the terminal device of the user, if the terminal device of the user is a smart phone and the data service of the smart phone is currently in an open state, an uplink is selected for uplink access, so that the data service of the smart phone can be normally used. And if the smart phone does not have data or voice service currently, selecting a supplementary uplink for uplink access so as to improve the utilization rate of air interface resources.
And step S300, selecting a corresponding frequency band for uplink access according to the frequency band interval.
In this embodiment, the corresponding frequency band may be selected for uplink access according to the determined frequency band interval, and since the corresponding relationship between the frequency band interval and the frequency band is preset, the corresponding frequency band may be directly selected for uplink access according to the preset corresponding relationship after the frequency band interval is determined. Specifically, the frequency band corresponding to the first interval is an uplink, and the frequency band corresponding to the second interval is a supplemental uplink, that is, when the frequency band interval corresponding to the radio signal strength parameter value is the first interval, and the frequency band corresponding to the first interval is the uplink, the uplink is selected for uplink access, and when the frequency band interval corresponding to the radio signal strength parameter value is the second interval, and the frequency band corresponding to the second interval is the supplemental uplink, the supplemental uplink is selected for uplink access.
In summary, in this embodiment, a radio signal strength parameter value of a downlink frequency band of a service area is first obtained, where the radio signal strength parameter value is an average value of signal powers received on all REs (resource elements) bearing reference signals in a certain symbol, and a frequency band interval corresponding to the radio signal strength parameter value is further determined according to the radio signal strength parameter value, and a corresponding frequency band is selected to perform uplink access by combining the radio signal strength parameter value and the frequency band interval, so that the frequency band is not independently determined by the radio signal strength parameter value when being accessed, so that a scheme for selecting access is more complete, and a suitable frequency band can be accurately selected to perform uplink access when interference occurs. For example, a user needs to perform uplink access to a smart phone in a cell where the user is located, first, a wireless signal strength parameter value of a downlink frequency band of the cell where the user is currently located needs to be obtained, and the wireless signal strength in the current cell can be reflected by the wireless signal strength parameter value, so that the user can select a corresponding frequency band according to the wireless signal strength parameter value to perform uplink access. And then comparing the acquired wireless signal strength parameter value with a preset first threshold value and a preset second threshold value respectively, if the wireless signal strength parameter value is greater than the first threshold value, judging that a frequency band interval corresponding to the wireless signal strength parameter value is a first interval, and directly selecting an uplink for uplink access according to the corresponding relation between the preset frequency band interval and the frequency band. If the wireless signal strength parameter value is smaller than the second threshold value, the wireless signal strength parameter value is measured at preset time intervals to obtain a measurement result, when the measurement result is smaller than the second threshold value, the current environment is poor or the interference is large, the frequency band interval corresponding to the wireless signal strength parameter value is determined to be the second interval, and a supplementary uplink is directly selected to carry out uplink access according to the corresponding relation between the preset frequency band interval and the frequency band. If the wireless signal strength parameter value is smaller than the first threshold and larger than the second threshold, the frequency band needs to be selected according to the current service state information of the smart phone of the user. And if the data or voice service does not exist in the smart phone, selecting to supplement the uplink access. Therefore, the embodiment selects the frequency band for uplink access by combining the wireless signal strength parameter value, the frequency band interval and the service state information, so that the judgment is not carried out by independently depending on the wireless signal strength parameter value when the frequency band is accessed, and the scheme for selecting access is perfected, so that the suitable frequency band can be accurately selected for uplink access when interference occurs.
