At present, at least four antennas need to be supported for receiving downlink data in NR mode, and at least two antennas need to be supported for receiving downlink data in LTE mode. And the different frequency bands may be different in the design of the front-end rf module and the receiving antenna. In order to reduce the cost and the difficulty of the radio frequency module, the antenna layout and the design, different modes in the same frequency band can multiplex the same antenna and related modules as much as possible. In a scenario where the frequency bands of the LTE mode and the NR mode overlap, for example, the NR mode is the frequency band N41, the LTE mode is the frequency band B41, and the two front-end antennas of the NR mode and the LTE mode are shared. The design has the advantages of reducing the number of antennas and the radio frequency front end and reducing the cost, and has the defects that under the double-card mode, two SIM cards respectively based on the NR mode and the LTE mode can generate antenna conflict in certain scenes, so that the performance of the SIM card based on the NR mode or the LTE mode is reduced, and even the situation of network disconnection occurs.

Detailed Description
In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below.
In order to reduce cost and area of antenna layout on hardware, two SIM cards based on NR mode and LTE mode in a mobile terminal multiplex the same radio frequency front end and antenna as much as possible on a multiplexed frequency band, and for this purpose, two front end antennas are shared by two SIM cards based on NR mode and LTE mode. As shown in fig. 1, the LTE mode of the card 1 and the NR mode of the card 2 use two shared antennas at some time, the NR mode needs to use antenna 0/1/4/5, and the LTE mode needs to use antenna 0/1. At this point, antenna 0/1 is in conflict. For example, when the NR mode of the card 2 performs data reception of 4 antennas and the PDSCH (Physical Downlink Shared Channel ) data of 3 layers or 4 layers is scheduled at this time, the LTE mode of the card 1 performs pilot measurement or paging (paging), and for this case, there may be two processing manners:
1. the LTE mode of card 1 cuts off the shared control right of the two antennas in this case, while the NR mode of card 2 loses the signals of the two antennas, and cannot decode the PDSCH of the correct 3/4 layer. If the GAP (intermittent time) time of the LTE mode pilot measurement is long and the period is short, the NR mode must fail a lot of decoding and the performance is degraded.
2. The NR mode of the card 2 still controls four antennas, and the LTE mode of the card 1 cannot perform inter-frequency measurement or other tasks, and at this time, although the performance of the NR mode can be guaranteed, the LTE mode of the card 1 cannot complete measurement or paging reception, and the LTE mode of the card 1 must drop out of the network.
In comparison with the two above-mentioned processing methods, the existing system will choose scheme 1, i.e. to ensure that card 1 does not drop off the network as much as possible, but this processing method will sacrifice the NR mode performance of card 2 to a great extent.
Aiming at the situation, in order to solve the problem that the performance of the dual-card mobile terminal based on the NR+LTE mode is reduced or even the network is dropped due to antenna conflict, the embodiment of the invention provides a performance optimizing device and a method for the dual-card mobile terminal, which pre-judges whether the antenna conflict exists or not in advance, and under the condition that the antenna conflict exists, the receiving antenna of the NR mode is modified to be 2, so as to solve the demodulation performance reduction caused by that two antennas have no signal under the 4 x 2MIMO (Multiple-Input Multiple-Output). Further, the pilot network is reported to the NR mode scheduling layer 2 or layer 1 data through RI (Rank Indication) of NR CSI (Channel State Information ).
Fig. 2 is a block diagram of a performance optimizing apparatus for a dual card mobile terminal according to an embodiment of the present invention.
In this embodiment, the dual-card mobile terminal performance optimization apparatus includes the following modules:
a first data-rate frame receiving module 21 for calculating data-rate frames of the NR mode;
a second data-rate frame receiving module 22, configured to calculate a data-rate frame in LTE mode;
the event arbitration module 23 is configured to determine whether an antenna collision exists according to the data burst frame of the NR mode and the data burst frame of the LTE mode, and perform physical layer adjustment processing when the antenna collision occurs.
It should be noted that the data burst frame may include time points and lengths of the downlink data to be received in different scenarios, that is, each time period of the downlink data to be received in different scenarios. The different scenarios include, but are not limited to, any one or more of the following: common frequency measurement, different frequency measurement, discontinuous reception, sleep, etc.
Each of the above-described data-rank frame receiving modules may calculate data-rank frames of a corresponding mode according to an RRC (Radio Resource Control ) network configuration in the respective mode. For example, for both LTE mode and NR mode, data frame scheduling may be performed according to the uplink and downlink configurations of each and the scheduling information of the current data transmission.
In one embodiment, as shown in fig. 3, the event arbitration module 23 may include the following units:
a collision judging unit 231 configured to judge whether there is an overlap between the data frame of the NR mode and the data frame of the LTE mode in terms of data reception time; if overlap exists, determining that antenna collision exists; otherwise, determining that no antenna conflict exists;
the decision control unit 232 is configured to perform physical layer adjustment processing in the case of an antenna collision, specifically, adjust the number of radio frequency antennas in the NR mode to 2, and allocate an antenna control right according to the adjusted antennas, that is, disconnect the control right of the NR radio frequency module to the shared 2 antennas, and control the same only by the LTE radio frequency module. In a specific implementation, switch control can be added between the shared antenna and the NR radio frequency module, so that control right distribution is conveniently realized.
Fig. 4 shows another block diagram of the event arbitration module 23.
Unlike the embodiment shown in fig. 3, in this embodiment, the event arbitration module 23 further includes:
a configuration information checking unit 233, configured to check whether a maximum value of RI (Rank Indicator) of the network configuration in the NR mode is less than 2 in case of an antenna collision.
Accordingly, in this embodiment, the decision control unit 232 is further configured to set the maximum value of RI to 1 when the configuration information checking unit 233 determines that the maximum value of RI of the network configuration in the NR mode is equal to or greater than 2. That is, the value of RI in CSI (Channel State Information ) reported to the network side by the NR mode-based SIM card is set to 1 to guide the network side to schedule the NR mode downlink data to be not more than layer 2 (layer).
The CSI is channel state information that the terminal is configured to feed back downlink channel quality to the gNB, where the gNB performs scheduling adjustment and beam management related work according to the reported content. In the NR system, the CSI includes CQI (Channel Quality Indicator ), PMI (Precoding Matrix Indicator, precoding matrix Indicator), CRI (CSI-RS Resource Indicator, CSI reference signal resource Indicator), SSBRI (SS/PBCH Block Resource Indicator, SSB resource Indicator), LI (Layer Indicator), RI, L1-RSRP (Layer 1Reference Signal Received Power ).
The performance optimizing device for the dual-card mobile terminal provided by the embodiment of the invention can be used for pre-judging whether the antenna conflict exists or not in advance and guaranteeing normal receiving of downlink data in the LTE mode through adjusting and processing a physical layer under the condition that the antenna conflict exists, so that the performance of the terminal is effectively improved.
Further, under the condition that antenna collision exists, not only is the antenna allocation and control right of a physical layer adjusted, but also the maximum value of RI reported by the NR mode CSI is adjusted to be 1, so that the scheduling of the network side on the downlink data of the NR mode is guided to be not more than 2 layers (layers), and the demodulation performance degradation caused by the fact that two antennas do not have signals under the 4 x 2MIMO is avoided. Therefore, the dual-card mobile terminal provided by the embodiment of the invention can ensure the normal receiving of the downlink data in the LTE mode and simultaneously greatly improve the performance of the NR mode.
Correspondingly, the embodiment of the invention also provides a terminal device, and fig. 5 is a structural block diagram of the terminal device in the embodiment of the invention.
The terminal device 500 includes an NR radio frequency module 31, an LTE radio frequency module 32, a SIM card based on an NR mode, and a SIM card based on an LTE mode. The NR radio frequency module 31 is connected with 4 antennas, the LTE radio frequency module 32 is connected with 2 antennas, and two of them share antennas.
As shown in fig. 5, the terminal device 500 further includes the aforementioned dual card mobile terminal performance optimization apparatus. By the device, under the condition of antenna conflict, the physical layer can be adjusted, normal receiving of LTE mode downlink data is ensured, and terminal performance is effectively improved. Further, when there is an antenna collision, the maximum value of RI reported by the NR mode CSI may be adjusted to 1, so that the scheduling of the network side on the downlink data of the NR mode is not greater than 2 layers (layers), thereby greatly improving the performance of the NR mode while ensuring normal reception of the downlink data of the LTE mode.
Correspondingly, the embodiment of the invention also provides a performance optimization method of the dual-card mobile terminal, aiming at the terminal equipment which is based on the dual-SIM card of the NR+LTE mode and has two shared antennas of the two SIM cards, the method pre-judges whether the antenna conflict exists in advance, and adjusts the physical layer under the condition that the antenna conflict exists, thereby improving the performance of the NR mode while ensuring the normal receiving of downlink data of the LTE mode.
As shown in fig. 6, a flowchart of a method for optimizing performance of a dual-card mobile terminal according to an embodiment of the present invention includes the following steps:
Specifically, the data burst in each mode may be calculated according to the RRC network configuration of the mode, i.e. the data burst in the NR mode is calculated according to the RRC network configuration of the NR mode, and the data burst in the LTE mode is calculated according to the RRC network configuration of the LTE mode.
It should be noted that the different scenarios may include, but are not limited to, any one or more of the following: common frequency measurement, different frequency measurement, discontinuous reception, sleep, etc.
The antenna collision is described in the background art, and mainly aims at the situation that the antenna collision is generated when the SIM card based on the NR mode and the LTE mode needs to receive downlink data at the same time, so that whether the NR mode and the LTE mode overlap in data receiving time can be judged according to the data frame of the NR mode and the data frame of the LTE mode; if overlap exists, determining that antenna collision exists; otherwise, it is determined that there is no antenna collision.
In step 603, physical layer adjustment processing is performed.
And step 604, reporting the RI maximum value in the CSI as a network configuration value by the SIM card based on the NR mode.
Most hardware currently limits the maximum number of antennas to 4 in NR mode. The processing of step 604 and step 605 is the same as that of the prior art, and will not be described in detail here.
In step 605, one adjustment processing method is to adjust the number of radio frequency antennas in the NR mode to 2, and allocate antenna control rights according to the adjusted antennas. That is, the control right of the NR radio frequency module to the shared 2 antennas is disconnected, and it is controlled only by the LTE radio frequency module. The other adjustment processing mode is to adjust the number of antennas and the control right, and further check whether the maximum value of RI of network configuration in NR mode is less than 2; if not, the maximum value of RI is set to 1. In this way, the scheduling of the network side to the downlink data of the NR mode is not more than 2 layers (layers), so as to avoid the demodulation performance degradation caused by no signals of two antennas under 4 x 2 MIMO.
According to the performance optimization method for the dual-card mobile terminal, provided by the embodiment of the invention, aiming at the problem that the performance of the dual-card mobile terminal based on the NR+LTE mode is reduced or even the network is dropped due to antenna conflict in the prior art, whether the antenna conflict exists or not is pre-judged in advance, and under the condition that the antenna conflict exists, the normal receiving of downlink data in the LTE mode can be ensured through adjusting and processing the physical layer, so that the performance of the terminal is effectively improved.
Further, under the condition that antenna collision exists, not only is the antenna allocation and control right of a physical layer adjusted, but also the maximum value of RI reported by the NR mode CSI is adjusted to be 1, so that the scheduling of the network side on the downlink data of the NR mode is guided to be not more than 2 layers (layers), and the demodulation performance degradation caused by the fact that two antennas do not have signals under the 4 x 2MIMO is avoided. Therefore, the dual-card mobile terminal provided by the embodiment of the invention can ensure the normal receiving of the downlink data in the LTE mode and simultaneously greatly improve the performance of the NR mode.
