Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Example one
In a mobile communication LTE system, CQI based on SRS measurement is used for uplink resource scheduling, and IRT based on SRS measurement is used for uplink synchronization. Therefore, if the SRS resource allocation is not reasonable, uplink CQI and IRT in the whole cell are abnormal, which affects the stability of the LTE system.
Referring to fig. 1, a flowchart illustrating steps of a SRS resource management method according to a first embodiment of the present invention is shown. In this embodiment, the SRS resource management method may, but is not limited to, implement reasonable allocation of SRS resources by two ways (SRS parameter determination way and resource conflict determination way). The SRS resources may be reasonably allocated only by the SRS parameter judgment mode or only by the resource conflict judgment mode, and certainly, the SRS resources may also be reasonably allocated according to a combination judgment mode of the SRS parameter judgment and the resource conflict judgment, where it needs to be noted that there is no inevitable sequence between the two judgment flows of the SRS parameter judgment and the resource conflict judgment.
Specifically, the SRS resource management method may include:
102, acquiring SRS parameters of a user, and judging whether the SRS parameters of the user are matched with cell parameters; when the SRS parameter of the user is determined not to be matched with the cell parameter, generating first alarm information; and sending the first alarm information to the RRC so that the RRC reconfigures the SRS resource according to the first alarm information.
In this embodiment, if the SRS parameter does not match the cell parameter, it indicates that the resource location allocated to the user is not suitable and/or is not allowed to transmit SRS data, and at this time, the SRS resource needs to be reconfigured. Specifically, first warning information may be generated and sent to the RRC, so that the RRC may reconfigure SRS resources according to the first warning information, thereby ensuring reliability of CQI and IRT measured based on SRS data.
And/or the presence of a gas in the gas,
104, acquiring resource position information of a user, judging whether the user has resource conflict with other existing alive users according to the resource position information of the user, and generating second alarm information when determining that the user has resource conflict with other existing alive users; and sending the second alarm information to the RRC so that the RRC reconfigures the SRS resource according to the second alarm information.
In this embodiment, if the user has a resource conflict with other existing surviving users, it indicates that the resource location allocated to the user is not suitable and/or not allowed to transmit SRS data, and at this time, the SRS resource needs to be reconfigured. Specifically, second warning information may be generated and sent to the RRC, so that the RRC may reconfigure SRS resources according to the second warning information, thereby ensuring reliability of CQI and IRT measured based on SRS data. For example, the RRC may release, according to the second warning information, other existing surviving users having resource conflict with the user, so as to implement reconfiguration of SRS resources.
Therefore, the SRS resource management method of the embodiment may generate the first warning information when the SRS parameter of the user is not matched with the cell parameter; and/or generating second alarm information when the user has resource conflict with other existing survival users; furthermore, the RRC may reconfigure the SRS resource according to the received first warning information and/or the second warning information, so as to improve the rationality of SRS resource allocation and management as a whole, and further enhance the reliability of CQI and IRT based on SRS measurement.
Example two
Referring to fig. 2, a flowchart illustrating a method for SRS resource management according to a second embodiment of the present invention is shown. In this embodiment, the SRS resource management method may be implemented based on, but not limited to, a Physical Layer (Physical Layer). As described above, the SRS resource management method can be implemented based on two manners of SRS parameter determination and resource determination, and the two manners of determination are described below.
Firstly, an SRS parameter judgment process:
in this embodiment, the SRS resource management method may include:
step 202, obtaining SRS parameters of the user.
In this embodiment, the SRS parameters include, but are not limited to: an SRS time domain parameter and an SRS frequency domain parameter.
Step 204, determining whether the SRS parameter of the user matches the cell parameter.
In this embodiment, the specific implementation manner of determining whether the SRS parameter of the user is matched with the cell parameter may be as follows: judging whether the SRS time domain parameters of the user are matched with the SRS subframe configuration of the cell; and/or judging whether the SRS frequency domain parameters of the user are matched with the bandwidth configuration of the cell.
Step 206, when it is determined that the SRS parameter of the user is not matched with the cell parameter, generating first warning information.
In this embodiment, it is preferable that, if the SRS time domain parameter of the user does not match the SRS subframe configuration of the cell, it indicates that the time domain resource location allocated to the user does not allow sending the SRS, and it may be determined that the user is an abnormal user, and at this time, the first warning information may be generated.
Preferably, if the SRS frequency domain parameter of the user does not match the bandwidth configuration of the cell, for example, the frequency domain resource allocated to the user exceeds the frequency domain bandwidth range of the cell, the user cannot be established again, it may be determined that the user is an abnormal user, and at this time, the first warning information may be generated.
The first warning information may carry SRS parameters and/or an abnormal type of the abnormal user.
And step 208, sending the first alarm information to the RRC, so that the RRC reconfigures the SRS resource according to the first alarm information.
In this embodiment, as described above, the first warning information may carry the SRS parameter and/or the abnormal type of the abnormal user, so that the RRC may reconfigure the SRS resource according to the SRS parameter and/or the abnormal type of the abnormal user carried in the first warning information.
Second, resource conflict judgment process
In this embodiment, the SRS resource management method may further include:
step 210, resource location information of the user is obtained.
In this embodiment, the acquiring resource location information of the user may specifically refer to acquiring SRS code domain location information of the user.
Step 212, determining whether the user has resource conflict with other existing alive users according to the resource location information of the user.
In this embodiment, since the user may have a resource conflict with other existing alive users during the establishment or reconfiguration, when the user is established or reconfigured, it is necessary to determine the resource of the user and determine whether the resource conflict exists between the user and other existing alive users.
Step 214, when it is determined that the user has resource conflict with other existing alive users, generating second warning information.
In this embodiment, when it is determined that the user has a resource conflict with other existing alive users, the second warning information may be generated simultaneously by whether the physical layer indicates the other existing alive users having the resource conflict with the user. The second warning information carries at least one of the released user information, resource location information and abnormal type of other existing alive users.
Step 216, sending the second warning information to the RRC, so that the RRC reconfigures the SRS resource according to the second warning information.
In this embodiment, as described above, the second warning information may carry at least one of the released user information, resource location information, and abnormal type of the other existing alive users, so that the RRC may reconfigure the SRS resource according to at least one of the released user information, resource location information, and abnormal type of the other existing alive users carried in the second warning information.
For example, when a user is established or reconfigured, if it is determined that the user has a resource conflict with other existing surviving users, the SRS resource of the other existing surviving users that conflict with the user may be released through a physical layer, and the second warning information is generated at the same time, and the released user information, resource location information, and abnormal type of the other existing surviving users are carried in the second warning information and sent to the RRC, so that the RRC may reconfigure the SRS resource according to the released user information, resource location information, and abnormal type of the other existing surviving users.
It should be noted that, in the process of reconfiguring the user, if the user has a resource conflict with itself, that is, the user is reconfigured at the original resource location, the current SRS resource allocation may be maintained, and no processing is performed.
It should be noted that, in this embodiment, there is no necessary sequence between the step 202 and the step 210, and the steps may be executed simultaneously or separately, and this embodiment does not limit this.
In this embodiment, the SRS resource management method may further include:
step 218, recording and managing the SRS parameter and/or resource location information of the user.
In this embodiment, recording and management of SRS parameters and/or resource location information of the user may be implemented in a physical layer. For example, the SRS parameters of other existing surviving users can be recorded by an array of flag bits: when a user establishes the resource, the corresponding resource position mark position is valid; when the user deletes the resource, clearing the corresponding resource position zone bit; when the user reconfigures, clearing the corresponding historical resource position flag bit, and enabling the reconfigured resource position flag bit to be effective; and in the user silent period, the resource position flag bit is not changed.
In summary, the SRS resource management method according to this embodiment may generate the first warning information when the SRS parameter of the user is not matched with the cell parameter; and/or generating second alarm information when the user has resource conflict with other existing survival users; furthermore, the RRC may reconfigure the SRS resource according to the received first warning information and/or the second warning information, so as to improve the rationality of SRS resource allocation and management as a whole, and further enhance the reliability of CQI and IRT based on SRS measurement. Secondly, the SRS resource management method can be realized based on a physical layer, and the robustness of the SRS module of the physical layer is enhanced.

When any judgment result is not matched, the following step 314 is executed; when the determination results are all matches, the following step 308 is performed.
And 308, acquiring resource position information of the user, and judging whether the user has resource conflict with other existing live users according to the resource position information of the user.
In this embodiment, if the user has a resource conflict with other existing surviving users, the following step 310 may be executed; if there is no conflict, step 312, described below, may be performed.
It should be noted that there is no necessary sequence between step 306 and step 308, and step 308 may be executed first and then step 306 according to actual situations, which is not limited in this embodiment.
Step 310, releasing the SRS resource of the other existing surviving users that conflict with the user, clearing the resource location flag of the other existing surviving users that conflict with the user, generating a second warning message, and sending the released user information, resource location information, and abnormal type of the other existing surviving users to the RRC in the second warning message.
Step 312, recording and saving the resource location identification bits of the user.
In this embodiment, when it is determined that the user does not have a resource conflict with other existing surviving users through step 308, the historical resource location flag bit of the user may be cleared, and the new resource location flag bit of the user is valid.
Step 314, generating and sending a first alarm message.
In this embodiment, when it is determined that the SRS parameter of the user is not matched with the cell parameter in step 306, it is determined that the user is an abnormal user, the first warning information is generated, and meanwhile, the SRS parameter and the abnormal type of the abnormal user are carried in the first warning information and sent to the RRC.
Step 316, clearing the resource location identification bits of the user.
In this embodiment, when it is determined that the user status is the delete status through step 302, the resource location flag of the user may be cleared.
In summary, the SRS resource management method according to this embodiment may generate the first warning information when the SRS parameter of the user is not matched with the cell parameter; and/or generating second alarm information when the user has resource conflict with other existing survival users; furthermore, the RRC may reconfigure the SRS resource according to the received first warning information and/or the second warning information, so as to improve the rationality of SRS resource allocation and management as a whole, and further enhance the reliability of CQI and IRT based on SRS measurement.
