Technical Field

Background
LTE CA technology will play an important role in mobile communications for a long time. LTE CA, LTE carrier aggregation, LTE long term evolution, may be simply understood as combining two different frequency bands to bind as a transmission bandwidth, where a Pcell (primary cell) establishes a cell for an initial connection of a UE (user equipment), and generally corresponds to a PCC (primary carrier) and a Scell reconfigures an added cell through RRC (connection configuration, radio resource control) to provide additional frequency band resources, and generally corresponds to a SCC (secondary carrier), where the PCC must configure DL (downlink) and UL (uplink) at the same time, and the SCC may configure only one DL or UL. Mobility information, security parameters, and the like of some NAS (Network Attached Storage) are only sent on PCC, and a terminal only initiates a random access procedure on a PCC carrier.
At present, in the process of communication by using the LTE CA technology, when some specific CAs are combined, PCC may appear to be uplink, the transmission frequency or the corresponding harmonic wave transmitted by the PCC may fall into the SCC downlink frequency band, which may cause interference to the SCC downlink and cause degradation of the receiving performance of the SCC. That is, during communication, interference is easily generated between the PCC and the SCC of the electronic device.

Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, in one embodiment, a timeslot adjusting method is provided and applied to an electronic device, and the method includes:
step 101: acquiring frequency band information of a first primary carrier PCC connected with the electronic equipment and frequency band information of a first secondary carrier SCC connected with the electronic equipment.
In the process of initially accessing the base station, the electronic device may establish a PCC connection, where the PCC connection is a first PCC, that is, the electronic device may perform data transmission in a frequency band corresponding to the first PCC. In one example, the frequency band information may be understood as a frequency band identifier, which may be used to uniquely indicate a frequency band. Besides establishing a PCC connection, the electronic device and the base station may also establish an SCC connection, so that frequency band information of a first primary carrier PCC connected to the electronic device and frequency band information of a first secondary carrier SCC connected to the electronic device may be obtained.
Step 102: and acquiring interference information of the frequency band information of the first PCC and the frequency band information of the first SCC from a preset carrier aggregation conflict table.
After the frequency band information of the connected first primary carrier PCC and the frequency band information of the connected first secondary carrier SCC are obtained, interference information corresponding to both the frequency band information of the first PCC and the frequency band information of the first SCC exists in the preset carrier aggregation collision table, and then the interference information of the frequency band information of the first PCC and the frequency band information of the first SCC can be obtained in the preset carrier aggregation collision table.
In an example, the preset carrier aggregation collision table may be determined in a development and design stage of the electronic device, that is, radio frequency performance of a CA combination supported by the electronic device is all tested, and a condition that PCC and SCC interfere with each other is obtained and stored in a table form, so as to obtain the preset carrier aggregation collision table. The preset carrier aggregation collision table may include N corresponding relationships, where each corresponding relationship includes one piece of PCC frequency band information, one piece of SCC frequency band information, and one piece of interference information, that is, the preset carrier aggregation collision table includes N pieces of interference information, and the PCC frequency band information and the SCC frequency band information corresponding to the N pieces of interference information, where N is a positive integer, and the PCC frequency band information or/and the SCC frequency band information in different corresponding relationships are different. The preset carrier aggregation collision table (i.e., CA collision combination table) in one example is shown in table 1.
Table 1 preset carrier aggregation collision table
Figure BDA0002331827700000041
As shown in table 1 above, the B1 frequency band and the B3 frequency band have a condition that PCC uplink signals interfere with SCC downlink signals, and the B7 frequency band and the B5 frequency band have a condition that SCC uplink signals interfere with PCC downlink signals. If the obtained frequency band information of the first PCC is a B1 frequency band and the frequency band information of the first SCC is a B3 frequency band, the obtained interference information between the frequency band information of the first PCC and the frequency band information of the first SCC is that an SCC uplink signal interferes with a PCC downlink signal.
Step 103: adjusting a transmission slot of the electronic device in at least one of the first PCC and the first SCC based on the interference information.
The adjusted uplink transmission time slot of the electronic device on the first PCC and the downlink transmission time slot of the first SCC are not overlapped, and/or the adjusted uplink transmission time slot of the electronic device on the first PCC and the uplink transmission time slot of the first SCC are not overlapped.
After obtaining the interference information corresponding to the frequency band information of the first PCC and the frequency band information of the first SCC, the interference form between the connected first PCC and the first SCC may be obtained, so that the transmission timeslot of the electronic device in at least one of the first PCC and the first SCC may be adjusted based on the interference information. Because the adjusted uplink transmission time slot of the electronic device on the first PCC and the downlink transmission time slot of the first SCC do not overlap, and/or the adjusted downlink transmission time slot of the electronic device on the first PCC and the uplink transmission time slot of the first SCC do not overlap, that is, the adjusted uplink transmission time slot of the electronic device on the first PCC and the downlink transmission time slot of the first SCC are staggered, and/or the adjusted downlink transmission time slot of the electronic device on the first PCC and the uplink transmission time slot of the first SCC are staggered, transmission interference between the first PCC and the first SCC of the electronic device can be reduced.
The foregoing time slot adjusting method may determine interference information based on the frequency band information of the connected first PCC and the frequency band information of the first SCC, and then adjust the transmission time slot of the electronic device in at least one of the first PCC and the first SCC by using the interference information, so that the uplink transmission time slot of the adjusted electronic device in the first PCC and the downlink transmission time slot of the first SCC are not overlapped, and/or the downlink transmission time slot of the adjusted electronic device in the first PCC and the uplink transmission time slot of the first SCC are not overlapped. Therefore, the adjusted uplink transmission time slot of the electronic device on the first PCC is staggered with the downlink transmission time slot of the first SCC, and/or the adjusted downlink transmission time slot of the electronic device on the first PCC is staggered with the uplink transmission time slot of the first SCC, so that transmission interference between the first PCC and the first SCC of the electronic device can be reduced.
In one embodiment, adjusting a transmission slot of an electronic device in at least one of a first PCC and a first SCC includes: acquiring an uplink data volume and a downlink data volume of the electronic equipment; and adjusting at least one of an uplink time transmission slot of the first PCC, a downlink transmission slot of the first PCC, an uplink transmission slot of the first SCC and a downlink transmission slot of the first SCC according to the uplink data amount, the downlink data amount and the interference information. That is, in this embodiment, referring to fig. 2, there is provided a timeslot adjusting method applied to an electronic device, the method including:
step 201: acquiring frequency band information of a first primary carrier PCC connected with the electronic equipment and frequency band information of a first secondary carrier SCC connected with the electronic equipment.
Step 202: and acquiring interference information of the frequency band information of the first PCC and the frequency band information of the first SCC from a preset carrier aggregation conflict table.
Step 203: and acquiring a target uplink data volume and a target downlink data volume of the electronic equipment.
Step 204: and adjusting at least one of an uplink time transmission slot of the first PCC, a downlink transmission slot of the first PCC, an uplink transmission slot of the first SCC and a downlink transmission slot of the first SCC according to the target uplink data amount, the target downlink data amount and the interference information.
The adjusted uplink transmission time slot of the electronic device on the first PCC and the downlink transmission time slot of the first SCC are not overlapped, and/or the adjusted uplink transmission time slot of the electronic device on the first PCC and the uplink transmission time slot of the first SCC are not overlapped.
The steps 201-202 correspond to the steps 101-102 one by one, and are not described herein again. The target uplink data amount may be understood as a data amount that the electronic device needs to send, for example, video data with a size of 1 megabyte needs to be requested by the electronic device, the electronic device may obtain the size of the data amount to be requested according to the request, that is, 1 megabyte, the target uplink data amount is 1 megabyte, and then the transmission timeslot is adjusted based on the target uplink data amount to be requested. The target downlink data amount may be understood as a data amount that needs to be received, for example, video data with a size of 0.5 million needs to be sent by the electronic device, and when the electronic device receives a request for sending the video data, the electronic device may obtain the size of the data amount to be sent, that is, 0.5 million, and then the target downlink data amount is 1 million, and then the transmission timeslot is adjusted based on the target uplink data amount to be sent. The electronic device accesses the first PCC and the first SCC, connects to the network, determines whether the network behavior of the electronic device is that the downlink throughput demand is greater or the uplink throughput demand is greater according to the data volume demand of the electronic device (including the uplink data volume demand and the downlink data volume demand, for example, the data request of an application, such as a digital voice service, a video call, and the like), and then performs slot adjustment according to the result. In this embodiment, in the transmission timeslot process, the target uplink data amount and the target downlink data amount of the electronic device are considered according to the interference information, so that the transmission interference can be further reduced.
In an embodiment, when the interference information is that the PCC uplink signal interferes with the SCC downlink signal, and the downlink data amount is greater than the uplink data amount, the number of the adjusted downlink transmission time slots of the electronic device in the first SCC is greater than the number of the adjusted downlink transmission time slots of the electronic device in the first PCC.
The downlink data volume is greater than the uplink data volume, which indicates that the throughput of the electronic device that needs to be downlink is relatively large, and the interference information is that PCC uplink signals interfere SCC downlink signals, and in order to better reduce transmission interference, more downlink transmission time slots need to be allocated to the first SCC, so that the necessary uplink transmission time slots of the first PCC are reserved to cope with the relatively large downlink data volume, and the uplink interference of the first SCC due to the necessary uplink transmission time slots is reduced.
And the electronic equipment determines an adjustment scheme of uplink and downlink transmission time slots of the electronic equipment according to the interference information and the data volume requirement. For example: the frequency band information of the connected first PCC is B1, and the frequency band information of the first SCC is B3, so that it can be determined that the interference information is that a PCC uplink signal interferes with an SCC downlink signal according to the preset carrier aggregation collision table, and because the network data volume requirement is that the downlink data volume is larger, in the time slot allocation, with downlink priority of the first SCC, downlink transmission time slots of the first SCC are arranged more, and only necessary uplink elaboration time slots of the first PCC are reserved, and in the downlink transmission time slots of the first SCC, the uplink transmission time slots of the first SCC are closed, so that the uplink signal of the first SCC is prevented from interfering with the downlink signal of the first SCC, and transmission interference is reduced.
In an embodiment, when the interference information is that the SCC uplink signal interferes with the PCC downlink signal, and the downlink data amount is greater than the uplink data amount, the number of the adjusted downlink transmission timeslots of the electronic device in the first PCC is greater than the number of the adjusted downlink transmission timeslots of the electronic device in the first SCC.
The downlink data amount is greater than the uplink data amount, which indicates that the throughput of the electronic device that needs to be downlink is relatively large, and the interference information is that the SCC uplink signal interferes with the PCC downlink signal, and in order to better reduce transmission interference, more downlink transmission time slots need to be allocated to the first PCC, so that the necessary uplink transmission time slots of the first SCC are reserved to cope with the relatively large downlink data amount, and the interference of the uplink transmission time slots to the first PCC is reduced.
In an embodiment, before obtaining frequency band information of a first primary carrier PCC connected to an electronic device and frequency band information of a first secondary carrier SCC connected to the electronic device, the method further includes: under the condition of being connected with a base station, receiving a Radio Resource Control (RRC) signaling sent by the base station, wherein the RRC signaling comprises frequency band information of a first SCC and frequency band information of a first PCC connected with an electronic device; and responding to the RRC signaling, and establishing SCC connection with the base station according to the frequency band information of the first SCC.
The method comprises the steps that the electronic equipment is connected into an LTE network in an actual working scene, at the moment, PCC connection is established, base station information is received, when conditions allow and the electronic equipment starts an LTE CA function, the base station can initiate an SCC connection command, namely RRC signaling, to the electronic equipment, the electronic equipment is connected with a first SCC, the RRC signaling can carry frequency band information of the first SCC and frequency band information of the connected first PCC, the electronic equipment establishes SCC connection after receiving the RRC signaling, the first SCC is connected, and therefore the electronic equipment can acquire the frequency band information of the connected first PCC and the frequency band information of the connected first SCC.
In the time slot adjusting method in the foregoing embodiment, uplink and downlink time slots of a PCC and an SCC in a specific combination are allocated, time-division staggering between a first PCC uplink and a first SCC downlink and time-division staggering between a first SCC uplink and a first PCC downlink are achieved, interference on the first PCC or the first SCC of the electronic device is reduced through flow determination, and user experience can be improved.
