Detailed Description
The terminology used in the description of the embodiments of the application herein is for the purpose of describing particular embodiments of the application only and is not intended to be limiting of the application.
In the application scenario of the embodiment of the present application, as shown in fig. 1, fig. 1 is a schematic diagram of a part of a structure of a terminal in the embodiment of the present application, where the terminal under NSA includes an NR system 1 and an LTE system 2, where the NR system 1 includes a first transmit path 1TX, a first receive path 1RX, a first antenna A1, a second antenna A2, and a double-pole double-throw switch P, the first transmit path 1TX and the first receive path 1RX are connected to the first antenna A1 and the second antenna A2 through the double-pole double-throw switch P, in a first switching state, a first pole two ends of the double-pole double-throw switch P are connected to the first transmit path 1TX and the second antenna A2, respectively, a second pole two ends of the double-pole double-throw switch P are connected to the first transmit path 1TX and the first antenna A1 respectively, and a second pole two ends of the double-throw switch P are connected to the first receive path 1RX and the second antenna A2 respectively, and in a second switching state, and the second pole two ends of the double-throw switch P are connected to the second antenna A3 and the second antenna A2 respectively. When the NR system 1 performs SRS transmission, for example, the double pole double throw switch P switches between the first switching state and the second switching state, even if the corresponding antenna of the NR system 1 performs the switching operation, at this time, signals received by the second receiving paths 2RX of the LTE system 2 through the third antenna A3 may be interfered by switching between the two antennas in the NR system 1.
As shown in fig. 2 and fig. 3, fig. 2 is a flowchart of a signal processing method of an LTE system in an embodiment of the present application, and fig. 3 is a schematic diagram of a time slot relationship between the LTE system and an NR system in an embodiment of the present application, where the embodiment of the present application provides a signal processing method of a long term evolution LTE system, including:
step 101, receiving a configuration duration KT sent by a new wireless NR system at a sending time Tt, where the configuration duration KT is a duration from the sending time Tt to an antenna switching time Ts, and the antenna switching time Ts is a time when an antenna corresponding to the NR system performs a switching operation;
102, calculating an antenna switching time Ts according to the configuration time KT;
and 103, compensating signals received by the LTE system at the antenna switching time Ts.
Specifically, in fig. 3, the first row represents a time slot relationship of the LTE system, L1 represents a time slot length of the LTE system, the second row represents a time slot relationship of the NR system, L0 represents a time slot length of the NR system, the NR system performs antenna switching configuration at a transmission time Tt, and simultaneously transmits a configuration time KT to the LTE system, the LTE system receives a message including the configuration time KT transmitted by the NR system at a time Tr, and the LTE system may calculate an antenna switching time Ts according to the configuration time KT in step 102, and then in step 103, compensate a signal received by the LTE system at the antenna switching time Ts to reduce an adverse effect on the LTE system caused by the antenna switching used by the NR system at the time.
According to the signal processing method of the LTE system, the configuration time length sent by the new wireless NR system at the sending time is received, and the antenna switching time is calculated according to the configuration time length, so that the signal received by the LTE system is compensated at the antenna switching time, the signal interference to the LTE system during the antenna switching of the NR system is reduced, and the antenna performance is improved.
Optionally, ts=tr+ (KT-MD), where Ts is the antenna switching time, tr is the time when the LTE system receives the configuration time, KT is the configuration time, MD is the transmission delay from the NR system to the LTE system, that is, the time between Tr and Tt, MD is a known fixed value, if the message transmission delay MD between the LTE system and the NR system is a fixed value, the LTE system may obtain the value, and in the step 102, the antenna switching time Ts is directly calculated according to the equation ts=tr+ (KT-MD) above.
Optionally, as shown in fig. 4, fig. 4 is a flowchart of another signal processing method of an LTE system according to an embodiment of the present application, where the method further includes:
step 100, acquiring synchronization deviation Te between an NR system and an LTE system and a time slot length relation between the NR system and the LTE system;
the step 102 of calculating the antenna switching time Ts according to the configuration time KT includes: and calculating the antenna switching time Ts according to the configuration time KT, the synchronization deviation Te between the NR system and the LTE system and the time slot length relation between the two systems.
Specifically, the information transmission delay MD between the LTE system and the NR system may be an uncertain value due to the influence of the system processing load, where the antenna switching time Ts cannot be calculated directly by using the above formula, but the synchronization deviation Te is a time difference between two system initial moments, for example, the time slot initial moment of the LET system is the T1 moment, the time slot initial moment of the NR system is the T2 moment, and the difference between the T2 moment and the T1 moment is the synchronization deviation Te by making the LTE system obtain the synchronization deviation Te and the time slot length relationship between the two systems in step 100; for another example, the slot length in the LTE system is L0, the slot length in the NR system is L1, l1=2×l0, and L1 is 2 times L0, which is the slot length relationship between two systems. When the message sending delay MD is an uncertain value, the LTE system needs to further calculate the antenna switching time Ts according to the above relationship.
Optionally, l1=m×l0, where L0 is the slot length of the NR system, L1 is the slot length of the LTE system, and m is a known positive integer; kt=xxl0-D, where KT is a configuration duration, x is a known positive integer, D < L0, D < L1, D is a known constant value; md=n×l1-Dm, where MD is a transmission delay from a transmission configuration duration of the NR system to the LTE system, N is a known positive integer, dm is an unknown number, and Dm is less than L1; te-D < Dm_min, dm_min is the minimum value of Dm, the value of n_L1 is obtained through calculation of n_L1=x multiplied by m-N, and the antenna switching time Ts is the time obtained by subtracting Te from the end of the n_L1+1 time slot of the time Tr starting when the LTE system receives the configuration time.
Specifically, the slot length L1 of the LET system is an integer multiple of the slot length L0 of the NR system, for example, as shown in fig. 3, m=2, i.e., L1 is 2 times L0, kt=x×l0-D means that the NR system delays a certain slot boundary by D time period as a transmission time Tt and a next slot boundary by D time period as an antenna switching time Ts, assuming that x=1, i.e., the NR system delays the second slot end by D time period as the transmission time Tt, transmits a message including the configuration time period KT to the LTE system at the time, and performs an antenna switching operation at the third slot end as the antenna switching time Ts. Let (KT-md+te)/(l1= [ (x×m-N) ×l1+te-D-Dm ] ++l1, where Dn is an unknown number and a remainder Dn is obtained, although Dn is unknown, dn may be ignored, if the value of n_l1 can be obtained, n_l1+1 represents a time slot boundary after Ts, which is the antenna switching time Ts, from Tr time instant minus Te, and based on Te-D < dm_min, -L1 < Te-D-Dm < 0, that is, (x×m-N) ×l1/(L1) is an integer, (Te-D-Dm)/(L1) is a number smaller than 1, that is, (KT-md+te)/(L1) is obtained, in the result, the integer n_l1=x×m-N is exactly, that is, the antenna switching time instant Ts can be obtained by directly calculating the value of n_l1 from the range of n_l1. For example, assuming that n=1, n_l1=x×m-n=1×2-1=1, according to calculation, the LTE system needs to subtract the duration Te at the 2 nd slot gap after the Tr time, that is, the antenna switching time Ts, and according to fig. 3, it can be seen that the calculation result is correct. As shown in fig. 5, fig. 5 is another schematic diagram of a slot relation between an LTE system and an NR system in the embodiment of the present application, where m=3, that is, L1 is 3 times L0, assuming that n=1, n_l1=x×m-n=1×3-1=2, according to calculation, it is known that the LTE system needs to subtract the duration Te at the 3 rd slot gap after the Tr time, that is, the antenna switching time Ts, and according to fig. 5, it can be seen that the calculation result is correct. As shown in fig. 6, fig. 6 is a schematic diagram of another time slot relationship between the LTE system and the NR system in the embodiment of the present application, where m=1, i.e. L1 is 1 time of L0, and assuming that n=1, d=0, n_l1=x×m-n=1×1-1=0, according to calculation, it is known that the LTE system needs to subtract the duration Te at the 1 st time slot gap after the Tr time, i.e. the antenna switching time Ts, and according to fig. 6, it can be seen that the calculation result is correct.
Optionally, the step 103 of compensating the signal received by the LTE system at the antenna switching time Ts includes: and acquiring a current antenna state at an antenna switching time Ts, determining a signal compensation value corresponding to the current antenna state according to a preset mapping relation, and compensating a signal received by the LTE system according to the signal compensation value corresponding to the current antenna state.
Specifically, the current antenna state corresponding to the terminal can be determined through a sensor in the terminal, the antenna state includes, for example, a free space state, a hand holding state, and a hand holding and approaching a head state, different effects are caused on signals in the LTE system when antennas corresponding to the NR system are switched in different holding states between the terminal (or the antenna) and a user, therefore, the corresponding signal influence compensation value can be obtained by testing in different antenna states in advance, and a specific compensation value is determined according to the current antenna state and a preset mapping relationship at the antenna switching time Ts, wherein the preset mapping relationship is used for reflecting the corresponding relationship between the current antenna state and the signal compensation value.
Optionally, the compensating the signal received by the LTE system at the antenna switching time Ts in step 103 includes performing phase compensation and amplitude compensation on the signal received by the LTE system.
Specifically, for example, testing is performed in different antenna states in advance to obtain corresponding signal compensation values, a lookup table between the different antenna states and the corresponding signal compensation values is established, for example, when detecting that the antenna corresponding to the NR system performs the switching operation in the free space state, the signal amplitude received by the LTE system is added with a value of-a and the phase is added with B, in the lookup table, the signal amplitude compensation value corresponding to the free space state is-a and the signal phase compensation value is-B, that is, in step 103, if the current antenna state obtained at the antenna switching time Ts is the free space state, the signal amplitude received by the LTE system is subtracted with a value of-B; when the antenna corresponding to the NR system is detected to perform the switching operation in the hand holding state, the signal amplitude received by the LTE system is added with C and the phase is added with E, and then in the lookup table, the signal amplitude compensation value corresponding to the hand holding state is-C and the signal phase compensation value is-E, that is, in step 103, if the antenna state acquired at the antenna switching time Ts is the hand holding state, the signal amplitude received by the LTE system is subtracted with C and the phase is subtracted with E.
Optionally, the time when the antenna corresponding to the NR system performs the switching operation is: the antenna corresponding to the NR system performs sounding reference signal SRS round trip operation, the antenna corresponding to the NR system is switched at the SRS round trip operation, the SRS round trip operation is periodically performed, the influence on signals in the LTE system is serious, and the signal compensation can be realized by utilizing the technical scheme of the application.
As shown in fig. 7, fig. 7 is a flowchart of a signal processing method of an NR system in an embodiment of the present application, where the signal processing method of a new wireless NR system includes:
step 201, configuring an antenna switching operation and transmitting a configuration duration KT to the LTE system at a transmission time Tt, where the configuration duration KT is a duration from the transmission time Tt to an antenna switching time Ts;
step 202, controlling the antenna corresponding to the NR system to execute the switching operation at the antenna switching time Ts.
Specifically, the execution bodies of step 201 and step 202 are both NR systems, and these two steps can be understood together with reference to the signal processing method of the above LTE system, where before the NR system performs the antenna operation after configuring the antenna switching operation, the NR system first sends a message to the LTE system at a sending time Tt, where the sent message includes a configuration time KT, so that the LTE system receives the message in step 101, calculates an antenna switching time Ts according to the configuration time KT in step 102, performs the switching operation at the antenna corresponding to the antenna switching time Ts and the NR system, and meanwhile, compensates for the received signal by the LTE system.
According to the signal processing method of the NR system, the configuration time is sent to the LTE system at the sending time, so that the LTE system can receive the configuration time, and the antenna switching time is calculated according to the configuration time, so that the signal received by the LTE system is compensated at the antenna switching time, the signal interference to the LTE system during the antenna switching of the NR system is reduced, and the antenna performance is improved.
