Detailed Description
The terminology used in the description of the embodiments section of the present application is for the purpose of describing particular embodiments of the present application only and is not intended to be limiting of the present application.
An application scenario of the embodiment of the present application is a terminal product having multiple antennas, as shown in fig. 1, fig. 1 is a schematic partial structure diagram of a terminal in the embodiment of the present application, a 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 a first antenna a1 and a second antenna a2 through a double-pole double-throw switch P, in a first switching state, a first pole both end of the double-pole double-throw switch P is connected to the first transmit path 1TX and the second antenna a2, a second pole both end of the double-pole double-throw switch P is connected to the first receive path 1RX and the first antenna a1, respectively, in a second switching state, a first pole both end of the double-pole double-throw switch P is connected to a first transmit path 1TX and a first antenna a1, the first reception path 1RX and the second antenna a2 are connected to both ends of the second pole of the double pole double throw switch P, respectively, and the LTE system 2 includes a second reception path 2RX and a third antenna A3 connected to the second reception path 2 RX. When the NR system 1 performs SRS polling, for example, the double pole double throw switch P switches between the first switching state and the second switching state, even if the antenna corresponding to the NR system 1 performs a switching operation, and at this time, signals received by the second receiving path 2RX of the LTE system 2 through the third antenna a3 are interfered by the switching of 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 an LTE system and an NR system in an embodiment of the present application, where an embodiment of the present application provides a signal processing method of an LTE system, including:
step 101, receiving a configured time length KT sent by a new wireless NR system at a sending time Tt, wherein the configured time length KT is a time length 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 executes switching operation;
102, calculating an antenna switching time Ts according to a configured time KT;
and 103, compensating the signal received by the LTE system at the antenna switching time Ts.
Specifically, the executing subjects of the above steps 101, 102, and 103 are LTE systems, in fig. 3, the first row represents a time slot relationship of the LTE system, L1 represents each time slot length in the LTE system, the second row represents a time slot relationship of the NR system, L0 represents each time slot length in the NR system, the NR system performs antenna switching configuration at the transmission time Tt and simultaneously transmits the configuration duration KT to the LTE system, the LTE system receives a message including the configuration duration KT transmitted by the NR system at the time Tr, the LTE system may calculate an antenna switching time Ts according to the configuration duration KT in step 102, and then compensate a signal received by the LTE system at the antenna switching time Ts in step 103, so as to reduce an adverse effect on the LTE system due to antenna switching used by the NR system at this time.
According to the signal processing method of the LTE system in the embodiment of the application, the configuration time 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, so that the signals received by the LTE system are compensated at the antenna switching time, the signal interference to the LTE system when the antenna of the NR system is switched is reduced, and the antenna performance is improved.
Optionally, Ts is antenna switching time, Tr is time when the LTE system receives the configured time, KT is configured time, MD is transmission delay from the NR system to the LTE system, that is, time between the Tr time and the Tt time, and 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 step 102, the antenna switching time Ts is directly calculated according to the above equation Ts ═ Tr + (KT-MD).
Optionally, as shown in fig. 4, fig. 4 is a flowchart of a signal processing method of another LTE system in this embodiment of the present application, where the method further includes:
step 100, acquiring a 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 configured duration KT includes: and calculating the antenna switching time Ts according to the configuration time KT, the synchronous deviation Te between the NR system and the LTE system and the time slot length relationship between the two systems.
Specifically, the message transmission delay MD between the LTE system and the NR system may be an uncertain value due to the influence of system processing load, and at this time, the antenna switching time Ts cannot be directly calculated by using the above formula, but the LTE system obtains a synchronization deviation Te and a time slot length relationship between the two systems in step 100, where the synchronization deviation Te is a time length difference between initial times of the two systems, for example, the time slot initial time of the LET system is time T1, the time slot initial time of the NR system is time T2, and a difference between the time T2 and the time T1 is the synchronization deviation Te; for another example, the slot length in the LTE system is L0, the slot length in the NR system is L1, L1 is 2 × L0, and L1 is 2 times of L0, which is the slot length relationship between the two systems. When the message transmission delay MD is an uncertain value, the LTE system needs to further calculate the antenna switching time Ts according to the above relationship.
Alternatively, 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 is x multiplied by L0-D, wherein KT is configuration duration, x is a known positive integer, D is less than L0, D is less than L1, and D is a known constant value; the method comprises the following steps that MD is N multiplied by L1-Dm, wherein MD is the transmission time delay from NR system transmission configuration duration to LTE system, N is a known positive integer, Dm is an unknown number, and Dm is less than L1; Te-D is less than Dm _ min, Dm _ min is the minimum value of Dm, the value of N _ L1 is obtained through calculation of N _ L1 which is x multiplied by m-N, and the antenna switching time Ts is the time of subtracting Te from the end of the nth _ L1+1 time slot of the time Tr beginning at the time when the configuration duration is received by the LTE system.
Specifically, the slot length L1 of the LET system is an integral multiple of the slot length L0 of the NR system, for example, as shown in fig. 3, m is 2, i.e., L1 is 2 times of L0, KT is x × L0-D, which means that the NR system delays a certain slot boundary by a duration of D as a transmission time Tt and takes a next slot boundary as an antenna switching time Ts, and assuming that x is 1, i.e., the NR system delays the end of the second slot by a duration of D as a transmission time Tt, a message including the configured time KT is transmitted to the LTE system at this time, and takes the end of the third slot as an antenna switching time Ts, at which an antenna switching operation is performed. Let (KT-MD + Te) ÷ L1 ═ [ (x × m-N). times.L 1+ Te-D-Dm ] +/L1, obtain the result including integer N _ L1 and remainder Dn, where Dn is an unknown number, although remainder Dn is unknown, but Dn can be ignored, if the value of N _ L1 can be obtained, then N _ L1+1 represents a slot boundary located after Ts from the time Tr, the slot boundary time minus Te is the antenna switching time Ts, and according to Te-D < Dm _ min, it can obtain-L1 < Te-D-Dm < 0, that is, (x × m-N). times.L 1 ÷ L1 is an integer, (Te-D-L1 is KT, that is a number less than 1, that is, in the result of (KT-MD + Te) L1, exactly, the integer N _ L1 ═ N-N, namely, the value of n _ L1 can be directly obtained according to the range of Dm, and then the antenna switching time Ts can be calculated. For example, assuming that N is 1, and N _ L1 is x × m-N is 1 × 2-1, it can be known from the calculation that the LTE system needs to subtract the time length Te at the 2 nd slot gap after the time Tr, that is, the antenna switching time Ts, and it can be seen from fig. 3 that the calculation result is correct. As shown in fig. 5, fig. 5 is a schematic diagram of another timeslot relationship between the LTE system and the NR system in the embodiment of the present application, where m is 3, that is, L1 is 3 times of L0, and if N is 1, N _ L1 is x × m-N is 1 × 3-1 is 2, it can be known from calculation that the LTE system needs to subtract the time length Te at the 3 rd timeslot gap after the time Tr, that is, the antenna switching time Ts, and it can be seen from fig. 5 that the calculation result is correct. As shown in fig. 6, fig. 6 is another schematic diagram of a time slot relationship between an LTE system and an NR system in the embodiment of the present application, where m is 1, that is, L1 is 1 times of L0, and assuming that N is 1, D is 0, and N _ L1 is x × m-N is 1 × 1-1, 0, it can be known from a calculation that the LTE system needs to subtract a time length Te at the 1 st time slot gap after Tr, that is, it is an antenna switching time Ts, and it can be seen from fig. 6 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 the current antenna state at the antenna switching time Ts, determining a signal compensation value corresponding to the current antenna state according to a preset mapping relation, and compensating the 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 may be determined by a sensor in the terminal, where the antenna state includes, for example, a free space state, a hand holding state and a head approaching state, and in different holding states between the terminal (or the antenna) and a user, different influences may be caused on signals in the LTE system when the antenna corresponding to the NR system is switched.
Optionally, in step 103, compensating the signal received by the LTE system at the antenna switching time Ts includes performing phase compensation and amplitude compensation on the signal received by the LTE system.
Specifically, for example, testing is performed in advance in different antenna states to obtain corresponding signal compensation values, and a lookup table between the different antenna states and the corresponding signal compensation values is established, for example, when it is detected that an antenna corresponding to the NR system performs a switching operation in a free space state, the amplitude and the phase of a signal received by the LTE system are increased by a and B, and then the amplitude compensation value of the signal corresponding to the free space state in the lookup table is-a and the phase compensation value of the signal 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 amplitude and the phase of the signal received by the LTE system are decreased by a and B; when detecting that the antenna corresponding to the NR system performs the switching operation in the hand-held state, the amplitude of the signal received by the LTE system is increased by C and the phase is increased by E, then the compensation value of the amplitude of the signal corresponding to the hand-held state in the look-up table is-C and the compensation value of the phase of the signal is-E, that is, in step 103, if the antenna state obtained at the antenna switching time Ts is the hand-held state, the amplitude of the signal received by the LTE system is decreased by C and the phase is decreased by E.
Optionally, the time when the antenna corresponding to the NR system performs the switching operation is: the antenna corresponding to the NR system is switched at the time of SRS polling operation executed by the antenna corresponding to the NR system, and the SRS polling operation is periodically executed, so that the influence on signals in the LTE system is serious, and the technical scheme of the application can be utilized to realize signal compensation.
As shown in fig. 7, fig. 7 is a flowchart of a signal processing method of an NR system according to an embodiment of the present application, and the present application provides a signal processing method of a new wireless NR system, including:
step 201, configuring antenna switching operation and sending a configured time length KT to an LTE system at a sending time Tt, wherein the configured time length KT is a time length from the sending time Tt to an antenna switching time Ts;
step 202, controlling the antenna corresponding to the NR system to perform a switching operation at the antenna switching time Ts.
Specifically, the executing subjects 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 LTE system, before the NR system executes antenna operation after configuring 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, and executes switching operation on an antenna corresponding to the NR system at the antenna switching time Ts, and at the same time, the LTE system compensates the received signal.
According to the signal processing method of the NR system in the embodiment of the application, 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 is reduced when the antenna of the NR system is switched, and the antenna performance is improved.
