Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
It should be appreciated that reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
In various embodiments of the present invention, it should be understood that the sequence numbers of the following processes do not mean the execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
In addition, the terms "system" and "network" are often used interchangeably herein.
As shown in fig. 1, an interference processing method according to an embodiment of the present invention is applied to a base station, and includes:
step 101, selecting a first target resource corresponding to a first terminal according to first measurement result information reported by the first terminal; the first terminal is a terminal supporting narrow-band measurement; the first measurement result information is a result obtained by the first terminal performing channel quality measurement on all the alternative resources.
Here, the first terminal supporting the narrowband measurement reports the first measurement result information, that is, the result obtained by performing the channel quality measurement on all the alternative resources. In this way, in this step, the base station can select the first target resource corresponding to the first terminal according to the first measurement result information reported by the first terminal, so as to execute the next step.
And 102, when the first target resource is a narrowband resource, configuring the first terminal to perform data transmission and channel quality measurement only on the first target resource within a preset time.
After selecting the first target resource in step 101, the base station knows that there is interference in transmission based on the fact that the first target resource is a narrowband resource. In this step, when the first target resource is a narrowband resource, the first terminal is configured to perform data transmission and channel quality measurement only on the first target resource within a preset time.
Thus, through steps 101 and 102, the base station can select a first target resource for the first terminal according to the result obtained by measuring the channel quality of the first terminal on all the alternative resources; and then when the first target resource is a narrowband resource, configuring the first terminal to perform data transmission and channel quality measurement only on the first target resource within a preset time, so that the first terminal can avoid resource waste of the data transmission and the channel quality measurement on the broadband resource within the preset time, and reduce power consumption of the terminal.
Wherein, the alternative resources comprise broadband resources and narrowband resources. For example, as shown in fig. 2, the bandwidth of the 5G base station communication is 100MHz, and includes resource a (60MHz), resource B (20MHz), and resource C (20 MHz). Correspondingly, the broadband resource of the communication between the terminal A and the 5G base station is resource A, resource B and resource C, the narrowband resource is resource A, resource B and resource C, and the combination of resource A, resource B and resource C. Therefore, the first measurement result information of terminal a will include the result of channel quality measurement performed on the wideband resource (a + B + C) and the narrowband resource (A, B, C, A + B, A + C, B + C). At this time, the bandwidth of the first 4G base station communication is 40MHz, including resource B and resource C, and the bandwidth of the second 4G base station communication is 20MHz, including resource C, so that there may be 20MHz and 40MHz overlapping networking situations between 5G and 4G. And the 5G base station applying the method of the embodiment of the invention selects the first target resource corresponding to the terminal A according to the first measurement result information, and the first target resource is the resource A, so that the terminal A can be configured to perform data transmission and channel quality measurement only on the resource A within the preset time because the first target resource is the narrow-band resource. Therefore, the terminal A can avoid resource waste of data transmission and channel quality measurement on broadband resources within the preset time, and the power consumption of the terminal is reduced.
Of course, reporting the first measurement result information by the first terminal may be implemented based on the configuration of the base station. For example, the first terminal receives transmission configuration information and measurement configuration information of the base station, where the transmission configuration information is used to configure the first terminal to perform data transmission on the broadband resource, and the measurement configuration information is used to configure the first terminal to perform channel quality measurement on all the alternative resources.
In this embodiment, optionally, step 101 includes:
obtaining the transmission rate of each alternative resource according to the first measurement result information;
and selecting the alternative resource with the maximum transmission rate from all the alternative resources as a first target resource.
Here, in consideration of the influence of the inter-system interference on the transmission rate, the transmission rate of each candidate resource is obtained based on the first measurement result information, and the candidate resource with the largest transmission rate is used as the first target resource. Thereafter, it is further determined whether the first target resource is a narrowband resource.
It should be appreciated that in this embodiment, the preset time may be set by the status timer TbandAnd (4) setting. Thus, when the first target resource is a narrowband resource, the base station activates the status timer. In the state timer, the base station performs data transmission and channel quality measurement configuration only on the selected alternative resource (the first target resource which is the narrowband resource).
Certainly, since the interference from the different system dynamically changes in both time and frequency domains, in order to adapt to the occurrence of dynamic change more, optionally, after the selecting the first target resource corresponding to the first terminal, the method further includes:
and when the first target resource is a narrow-band resource, the first terminal is configured to resume data transmission on the wide-band resource and perform channel quality measurement on the alternative resource after the preset time expires.
Here, for the case that the first target resource is a narrowband resource, it is configured that, after the preset time expires, the first terminal resumes data transmission on the wideband resource and performs channel quality on the alternative resourceAnd measuring the quantity, and then, timely adjusting the dynamic change of the interference of the different systems. Of course, if the preset time is passed through the status timer TbandAnd setting, after the timer is overtime, the data transmission between the first terminal and the base station can be restored to the full bandwidth, and the channel quality measurement on the alternative resource is carried out, so that the adaptive transmission adjustment can be carried out according to the current interference.
In this embodiment, optionally, after the selecting the first target resource corresponding to the first terminal, the method further includes:
when the first target resource is a narrow-band resource, acquiring a beam direction in which the first terminal is located;
storing the corresponding relation among the beam direction of the first terminal, the second measurement result information and the first target resource;
and the second measurement result information is a result obtained by the first terminal performing channel quality measurement on broadband resources in the first measurement result information.
Here, the beam direction in which the first terminal is located is determined by the base station based on the SRS of the first terminal, and of course, when the beam direction needs to be acquired, the base station configures the first terminal to transmit the SRS, for example, transmits configuration information of the SRS to the first terminal to trigger the first terminal to transmit the SRS.
Thus, for the case that the first target resource is a narrowband resource, the beam direction in which the first terminal is located is obtained, so that the beam direction, the second measurement result information (i.e., the result obtained by the first terminal performing channel quality measurement on the wideband resource in the first measurement result information), and the first target resource are correspondingly stored, so as to determine the transmission resource of the terminal that does not support narrowband measurement in the same application scenario.
Thus, in the case of facing a terminal that does not support narrowband measurement, in this embodiment, as shown in fig. 3, the method further includes:
step 301, obtaining a beam direction of a second terminal and third measurement result information;
step 302, according to the beam direction of the second terminal and the third measurement result information, querying a corresponding second target resource in stored information;
step 303, if the second target resource is queried, performing data transmission on the second target resource;
step 304, if the second target resource is not inquired, performing data transmission on a preset narrow-band resource;
the second terminal is a terminal which does not support narrow-band measurement;
the third measurement result information is a result obtained by the second terminal performing channel quality measurement on the broadband resource.
Here, the stored information is a correspondence relationship among stored beam directions, measurement result information, and resources when other terminals supporting narrowband measurement stored in the base station select a narrowband resource for transmission, for example, a correspondence relationship among a beam direction in which the first terminal is located, second measurement result information, and a first target resource is stored. Thus, for a terminal that does not support narrowband measurement, since the channel quality on the narrowband resource cannot be directly measured, according to the above step 301-304, the beam direction where the second terminal is located and the result obtained by the second terminal performing channel quality measurement on the wideband resource are obtained first, and then the second target resource is queried in the stored information, and the transmission resource can be selected by referring to the processing of other terminals that support narrowband measurement in the same scenario.
For example, the base station has stored information that the beam direction 1 of the terminal a (the terminal supporting the narrowband measurement) is recorded, and when only the narrowband resource a is transmitted, the wideband measurement result information (i.e., the result of performing the channel quality measurement on the wideband resource) is M. And for the terminal B which does not support the narrow-band measurement, if the obtained beam direction 1 and the broadband measurement result information are M, the application scene of the terminal B can be transmitted only in the narrow-band resource A.
Of course, if the used resource is not found in the stored information, the data transmission will be performed on the preset narrowband resource. The preset narrowband resource is preset, such as narrowband resource A; or, the preset narrowband resource is that the base station increases in sequence based on the terminal service requirement, and selects resources, such as a + B, a + B + C.
The beam direction in which the second terminal is located may also be determined by the base station based on the SRS of the second terminal, and of course, when the beam direction needs to be acquired, the base station may configure the second terminal to transmit the SRS, for example, transmit the SRS configuration information to the second terminal to trigger the second terminal to transmit the SRS.
As can be seen from the above, the embodiment further includes:
sending configuration information;
wherein the configuration information comprises configuration information of a channel sounding reference signal and/or configuration information of channel quality measurement;
the channel sounding reference signal is used for judging the beam direction.
The configuration information of the SRS is used for configuring the terminal to transmit the SRS, and the configuration information of the channel quality measurement is used for configuring the terminal to carry out the channel quality measurement. Of course, the configuration information may also include transmission configuration information, configuring the terminal to perform data transmission on the wideband resource or the narrowband resource, and so on.
In addition, in this embodiment, the channel quality measurement result information may include a channel quality indicator CQI, a precoding matrix indicator PMI, a RANK indicator RANK, and the like, which are not listed herein.
In summary, the method of the embodiment of the present invention can select a transmittable frequency for a terminal supporting frequency selective scheduling based on the frequency selective scheduling, and configure a pilot frequency and a status timer for a selected frequency combination, so as to reduce pilot frequency overhead and save power consumption of the terminal, and randomize interference of different systems by semi-static resource scheduling; for a terminal which does not support frequency selection scheduling, the SRS and the broadband measurement information of the terminal can be measured and compared with network storage information, so that the optimal scheduling resource is determined, and the rate is increased.
As shown in fig. 4, an interference processing method according to an embodiment of the present invention is applied to a terminal, and includes:
step 401, reporting first measurement result information;
and the first measurement result information is the result obtained by the terminal performing channel quality measurement on all the alternative resources.
Here, the terminal to which the method of the embodiment of the present invention is applied is a terminal that supports narrowband measurement (i.e., the first terminal of the previous embodiment), and reports a result obtained by performing channel quality measurement on all candidate resources to the base station, and the base station selects the first target resource corresponding to the first terminal according to the first measurement result information, and when the first target resource is a narrowband resource, configures the first terminal to perform data transmission and channel quality measurement only on the first target resource within a preset time, so that the first terminal can avoid resource waste of data transmission and channel quality measurement on a wideband resource within the preset time, and reduce power consumption of the terminal.
Optionally, after reporting the first measurement result information, the method further includes:
performing data transmission and channel quality measurement on a first target resource;
wherein the first target resource is an alternative resource with the maximum transmission rate among all alternative resources.
Here, the first target resource is a first target resource selected by the base station according to the first measurement result information, and is a candidate resource with the highest transmission rate among all candidate resources, so that the terminal performs data transmission and channel quality measurement on the first target resource.
Optionally, the method further comprises:
receiving configuration information of a base station;
wherein the configuration information comprises configuration information of a channel sounding reference signal and/or configuration information of channel quality measurement;
the channel sounding reference signal is used for judging the beam direction.
The terminal can perform operations such as SRS transmission, channel quality measurement and the like based on the received configuration information of the base station. Of course, the configuration information may also include transmission configuration information, configure the terminal to perform data transmission on the wideband resource or the narrowband resource, and so on.
In addition, as can be seen from the implementation manner of the interference processing method applied to the base station in the previous application, the first terminal may further perform: and transmitting the SRS to the base station, and acquiring the beam direction of the first terminal by the base station, so as to store the corresponding relation among the beam direction of the first terminal, the second measurement result information and the first target resource, thereby being convenient for determining the transmission resource of the terminal which does not support the narrow-band measurement in the same application scene.
It should be noted that, the implementation manner of the first terminal in the interference processing method embodiment applied to the base station in the previous application is applicable to this embodiment, and the same technical effect can be achieved.
