The method for processing the conflict between the SRS and the uplink resource provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings through some embodiments and application scenarios thereof.

When the ports of the SRS are multiplexed by using the TD-OCC sequence, since the ports of the SRS will be mapped to a plurality of symbols corresponding to the TD-OCC sequence, only discarding the SRS on the conflicting symbols may not ensure orthogonality of the TD-OCC, and thus the network side device may not correctly perform channel estimation. Meanwhile, when the ports of the SRS are multiplexed in the TDM manner, since the ports of the SRS are mapped to a plurality of symbols, if part of the symbols collide with uplink resources, the transmission performance of the SRS is affected.

In order to solve the problem of influencing SRS transmission performance when SRS collides with uplink resources in the case that ports of SRS are multiplexed in a TD-OCC or TDM manner, as shown in fig. 2, an embodiment of the present application provides a method 200 for processing the collision between SRS and uplink resources, which may be executed by a terminal, in other words, may be executed by software or hardware installed in the terminal.

S202: when the SRS and the uplink resource collide on N symbols, the terminal determines the SRS sending mode according to a first processing rule; the SRS port multiplexing mode comprises multiplexing by adopting a TD-OCC sequence with a length of L or multiplexing by adopting TDM; the first processing rule includes at least one of: discarding D symbols in the SRS occupied symbols, wherein the D symbols comprise the N symbols with collision; transmitting all or part of ports of the SRS on S reserved symbols, wherein the reserved symbols are symbols which are not discarded in the SRS occupied symbols; n, L, D and S are positive integers.

The uplink resources mentioned in the embodiments of the present application may include at least one of the following: other SRS (i.e., SRS other than the SRS introduced in S202), physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), physical uplink control channel (Physical Uplink Control Channel, PUCCH), time-frequency resources indicated by uplink cancellation indication (Cancelation indication, CI), and other time-frequency resources determined by specific rules or signaling for canceling or muting SRS transmission.

In this embodiment of the present application, when the ports of the SRS are multiplexed in the TDM manner, the ports of the SRS may be mapped on different symbols, for example, as shown in fig. 3, ports 0 to 3 of the SRS are mapped on symbol #1 and ports 4 to 7 are mapped on symbol # 2.

In the embodiment of the present application, the SRS occupation symbol may be an occupation symbol of the SRS in one slot.

In this embodiment of the present application, the terminal executing the first processing rule may further include the following conditions: the priority of the SRS is lower than the priority of the channel or signal transmitted on the uplink resource.

In the method for processing conflict between SRS and uplink resources provided in the embodiment of the present application, when the ports of the SRS are multiplexed in a TD-OCC sequence or TDM manner, if the SRS and the uplink resources conflict on N symbols, the terminal may determine, according to a first processing rule, a transmission manner of the SRS, where the first processing rule includes at least one of: discarding D symbols in the SRS occupied symbols; all or part of the ports of the SRS are transmitted on S reserved symbols. According to the embodiment of the application, the behavior of the terminal in the case of conflict is defined through the first processing rule, so that the performance of SRS transmission of the terminal is guaranteed, and the performance of a communication system is improved.

Optionally, all or part of the ports mentioned in the first rule for transmitting the SRS on the S reserved symbols include any one of the following:

1) And all P ports of the SRS are sent on the S reserved symbols, wherein P is a positive integer.

And all P ports for transmitting the SRS on the S reserved symbols meet at least one of the following conditions:

a. there is a third reserved symbol, where the third reserved symbol is all symbols of one or more symbol groups mapped by the TD-OCC sequence, the third reserved symbol belongs to the S reserved symbols, and the symbol groups include L symbols, where the L symbols may be L symbols mapped by the TD-OCC sequence.

In this embodiment, the discarded SRS does not affect the orthogonality of the TD-OCC, thereby ensuring the channel estimation performance of the SRS.

b. And a fourth reserved symbol exists, on the fourth reserved symbol, the sub-sequences or the combination of the sub-sequences corresponding to the P ports respectively meet orthogonality, the sub-sequences are the sub-sequences of the TD-OCC sequence, and the fourth reserved symbol belongs to the S reserved symbols.

c. The TD-OCC sequences corresponding to the P ports respectively are preset sequences. For example, the number of ports of SRS is 2, and the TD-OCC sequences corresponding to the 2 ports of SRS are [ +1, +1] and [ +1, -1, +1, -1] respectively. At this time, if the reserved symbol number S is 2, and 2 ports of the SRS correspond to the first two elements of the TD-OCC sequences [ +1, +1] and [ +1, -1, +1, -1] on the 2 reserved symbols, i.e., [ +1, +1] and [ +1, -1]. Since [ +1, +1] and [ +1, -1] are still orthogonal to each other, the number of ports of SRS transmitted over the 2 reserved symbols is still 2.

2) And transmitting X ports in all P ports of the SRS on the S reserved symbols, wherein P and X are positive integers, and X < P.

And X ports in all P ports for transmitting the SRS on the S reserved symbols meet one of the following conditions:

a. at least one symbol group mapped by the TD-OCC sequence contains conflicting symbols, wherein the symbol group contains L symbols, and the L symbols can be L symbols mapped by the TD-OCC sequence.

b. Each symbol group mapped by the TD-OCC sequence comprises L symbols, and the L symbols can be L symbols mapped by the TD-OCC sequence.

3) Transmitting all P ports of the SRS on a first reserved symbol, and transmitting X ports of all P ports of the SRS on a second reserved symbol, wherein the first reserved symbol and the second reserved symbol belong to the S reserved symbols; wherein P and X are positive integers, and X < P.

And transmitting all P ports of the SRS on a first reserved symbol, and transmitting X ports of all P ports of the SRS on a second reserved symbol, wherein the following conditions are satisfied: the first reserved symbols are all symbols of one or more symbol groups mapped by the TD-OCC sequence, no symbol with collision exists in the one or more symbol groups, and the symbol groups comprise L symbols; the second reserved symbol is a part of symbols of one or more symbol groups mapped by the TD-OCC sequence, wherein conflicting symbols exist in the one or more symbol groups, and the symbol groups comprise L symbols.

The embodiments 1) to 3) above propose a processing rule applicable to TD-OCC to solve the problem of collision between SRS and uplink resources, where the discarded SRS on the collided symbols does not affect the orthogonality of TD-OCC, so as to ensure the channel estimation performance of SRS.

The processing rules in 1) to 3) above are equally applicable to the case where the SRS ports are multiplexed in TDM. For example, ports 0 to 3 of SRS are mapped on symbol #1, and ports 4 to 7 are mapped on symbol #2. If the SRS collides with the uplink resource on the symbol #1, ports 0 to 3 of the SRS on the symbol #1 may be discarded, and only ports 4 to 7 of the SRS on the symbol #2 (reserved symbol) may be transmitted, or ports 0 to 7 of the SRS on the symbol #1 and the symbol #2, that is, all ports of the SRS may be discarded, and no reserved symbol is present.

In addition, when the conflict occurs, the mode that part of SRS ports still transmit is reserved, so that the utilization rate of uplink transmission resources and the updating efficiency of an uplink channel can be improved to the greatest extent.

Optionally, the X ports mentioned in the above embodiments are determined according to at least one of:

1) The network side device configures or instructs.

2) Determined according to a first rule; wherein the first rule comprises: the index of the X ports is minimum or maximum; or, the indexes of the X ports are first indexes, and the first indexes are related to the TD-OCC sequence; or, the index of the X ports is a second index, where the second index relates to the antenna correlation capability of the terminal, for example, the X ports have antenna correlation, that is, belong to the same correlated antenna port group.

Further, the subsequence or the combination of subsequences corresponding to the first index satisfies orthogonality, and the subsequence is a subsequence of the TD-OCC sequence.

Further, the length of the subsequence or the subsequence combination is 1/A of the length of the TD-OCC sequence, wherein A is a positive even number.

3) Determined according to a second rule; wherein the second rule comprises: the X ports are X ports that alternate among the all P ports, for example, X ports that alternate among the all P ports by index size.

The method provided by this embodiment further comprises the steps of: the terminal enables or disables the alternation according to the configuration of the network side equipment, i.e. the terminal can turn on/off the alternation according to the configuration of the network side.

Optionally, the value of X mentioned in the above embodiments is related to at least one of: the time domain positions of the N conflicting symbols; and the value of N is taken.

Optionally, the first processing rule relates to at least one of: the number of occupied symbols of the SRS; the repetition number of the SRS; the length L of the TD-OCC sequence; the time domain positions of the N conflicting symbols; the TD-OCC sequence.

Optionally, the D discarded symbols in the above embodiments include one of: 1) The N conflicting symbols; 2) The N conflicting symbols and M additional symbols.

The additional symbols may be determined by the time domain positions of the N conflicting symbols, including any one of: 1) The additional symbols are adjacent to the N conflicting symbols; 2) The additional symbols are the least or the greatest indexed symbols in the symbol group mapped by the TD-OCC sequence, and the symbol group comprises L symbols.

Optionally, on the basis of the foregoing embodiments, the discarding D symbols in the SRS occupation symbol includes: in the case that one or more conflicting symbols exist in the symbol group mapped by the TD-OCC sequence, one of the following is performed:

1) L symbols are discarded, wherein the L symbols are all symbols of the symbol group, and L is less than or equal to D.

2) K symbols in L symbols are discarded, wherein the L symbols are all symbols of the symbol group, and K < L is less than or equal to D.

Optionally, based on the above embodiments, the collision between the SRS and the uplink resource on N symbols includes: the SRS and the uplink resource are overlapped on the same symbol; wherein said overlapping on the same symbol comprises at least one of: 1) Overlapping occurs on the same symbol and the same frequency domain resource; 2) The overlap occurs only on the same symbol and does not occur on the frequency domain resources.

Optionally, on the basis of the above embodiments, the method further includes: the terminal determines a transmission precoding matrix indicator (Transmitted Precoding Matrix Indicator, TPMI) corresponding to the SRS according to a preset number of ports, where the preset number of ports includes any one of the following: 1) The number of all ports of the SRS; 2) The number of ports sent on the reserved symbol.

Optionally, the number of ports sent on the reserved symbol includes any one of the following: 1) The maximum port number of the ports sent on the reserved symbol; 2) The minimum port number of the ports sent on the reserved symbol; 3) The number of ports in the port set of ports transmitted on the reserved symbol.

In order to describe the collision processing method of the SRS and the uplink resource in detail provided in the embodiments of the present application, the following description will be made with reference to several specific embodiments.

Example 1

In this embodiment, as shown in fig. 4, the number of occupied symbols ns=2 of SRS, the number of repetition r=2 of SRS, and the number of 8 ports of SRS are multiplexed on symbols #1 and #2 using TD-OCC of length l=2. Wherein the TD-OCC sequence corresponding to ports 0-3 is [ +1, +1], and the TD-OCC sequence corresponding to ports 4-7 is [ +1, -1].

The terminal determines the sending mode of the SRS according to the first processing rule, and the sending mode is specifically as follows:

1) When the SRS collides with the uplink resource on n=1 symbols (taking the collision on symbol #1 as an example), there are the following two processing manners:

a. discarding the symbol being symbol #1 may be understood as discarding n=1 symbols where a collision occurs, or discarding k=1 symbols out of l=2 symbols of the symbol group of the TD-OCC map. The reserved symbol is symbol #2, and on reserved symbol #2, x=4 ports are transmitted, where x=4 ports may be determined as ports 0 to 3 (X ports with the smallest index) or ports 4 to 7 (X ports with the largest index) according to the first rule. In addition, x=4 ports may be alternately changed according to the second rule, for example, when the first collision occurs, the x=4 ports are ports 0 to 3 (X ports with the smallest index), and when the subsequent second collision occurs, the x=4 ports are alternately changed to ports 4 to 7 (X ports with the largest index), so that the cycle is alternated. The advantages of this treatment are: the network side can update the channels on all ports in time, so that the overall channel estimation performance is improved.

b. Discard symbols are symbols #1 and #2, no reserved symbols, and symbol #2 is m=1 additional symbols discarded. At this time, it can also be understood that: of the l=2 symbols (# 1 and # 2) of the length-2 TD-OCC mapped symbol group, there are n=1 collision symbols, and thus all l=2 symbols are discarded. At this time, the SRS occupation symbols are discarded, and thus the SRS is not transmitted.

2) Similarly, when the SRS collides with the uplink resource on symbol # 2: discard symbol is symbol #2 and reserve symbol is symbol #1. Alternatively, symbols #1 and #2 are both discarded symbols. The determination manner of the X ports is similar to that of the 1), and is not repeated.

3) When the SRS collides with the uplink resource on symbols #1 and #2, i.e., the number of symbols n=2 where the collision occurs: the discard symbols are #1 and #2, i.e., all n=l=2 symbols are discarded. At this time, the SRS is not transmitted because the SRS occupation symbols are discarded.

Example two

In this embodiment, as shown in fig. 5, the number Ns of occupied symbols of the SRS is=4, the number R of repetitions of the SRS is=2, and the 8 ports of the SRS are multiplexed on symbols #1 and #2 and #3 and #4 with TD-OCC length l=2, that is, ns symbols occupied by the SRS are divided into 2 symbol groups based on TD-OCC with the length l=2 of the TD-OCC as granularity. Wherein the TD-OCC sequence corresponding to ports 0-3 is [ +1, +1], and the TD-OCC sequence corresponding to ports 4-7 is [ +1, -1].

1) When the SRS collides with the uplink resource on n=1 symbols, taking the example that the collision occurs on symbol #1, there are the following three processing methods:

a. Discarding the symbol is symbol #1, reserving the symbols as symbol #2, symbol #3 and symbol #4, i.e., discarding k=1 symbols out of l=2 symbols of the first symbol group (symbol #1 and symbol # 2), and reserving l=2 symbols of the second symbol group (symbol #3 and symbol # 4). At this time, x=4 ports are sent on the reserved symbol #2 (the selection of the x=4 ports may be determined according to the first rule, the second rule, the network side configuration, etc., which are not described in detail herein); all p=8 ports are sent on reserved symbol #3 and reserved symbol # 4. Note that, at this time, the reserved symbol #3 and the reserved symbol #4 are the first reserved symbol, and the reserved symbol #2 is the second reserved symbol.

b. Discarding the symbol is symbol #1, reserving the symbols as symbol #2, symbol #3 and symbol #4, i.e., discarding k=1 symbols out of l=2 symbols of the first symbol group (symbol #1 and symbol # 2), and reserving l=2 symbols of the second symbol group (symbol #3 and symbol # 4). At this time, all p=8 ports are transmitted on reserved symbol #2, reserved symbol #3, and reserved symbol # 4. In this case, p=8 ports can also be transmitted on reserved symbol #2 because the combination of the sub-sequences of TD-OCC corresponding to SRS ports satisfies orthogonality, i.e., the combination of sub-sequences of ports 0 to 3 [ +1, +1] and the combination of sub-sequences of ports 4 to 7 [ -1, +1] are orthogonal to each other on reserved symbol #2 and reserved symbol # 3. Note that, at this time, the reserved symbol #3 and the reserved symbol #4 are the third reserved symbol, and the reserved symbol #2 and the reserved symbol #3 are the fourth reserved symbol.

c. Discarding the symbols are symbol #1 and symbol #2, reserving the symbols are symbol #3 and symbol #4, i.e., discarding all l=2 symbols of the first symbol group (symbol #1 and symbol # 2), and symbol #2 is an additional symbol discarded, and l=2 symbols of the second symbol group (symbol #3 and symbol # 4) are reserved. At this time, all p=8 ports are transmitted only on reserved symbol #3 and reserved symbol #4.

2) When the SRS collides with the uplink resource on n=2 symbols, taking the example that the collision occurs on symbol #1 and symbol #3, there are the following two processing manners:

a. discarding symbols are symbol #1 and symbol #3, and reserving symbols are symbol #2 and symbol #4. Only x=4 ports are sent on reserved symbols. Wherein x=4 ports on symbol #2 and symbol #4 are the same, for example, X ports on symbol #2 and symbol #4 are ports 0 to 3.

b. Discarding symbols are symbol #1 and symbol #3, and reserving symbols are symbol #2 and symbol #4. Only x=4 ports are sent on reserved symbols. Wherein the X ports on symbol #2 and symbol #4 are different, for example, the X ports on symbol #2 are ports 0 to 3, and the X ports on symbol #4 are ports 4 to 7.

3) When the SRS collides with the uplink resource on n=2 symbols, taking the example that the collision occurs on symbol #2 and symbol #3, there are the following three processing methods:
