The conflict handling method between SRS and uplink resources provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through some embodiments and application scenarios.

When the SRS port uses the TD-OCC sequence for multiplexing, the SRS port will be mapped Since there are multiple symbols corresponding to the TD-OCC sequence, discarding only the SRS on the conflicting symbols may not ensure the orthogonality of TD-OCC, causing the network side equipment to be unable to correctly estimate the channel. At the same time, when the SRS ports are multiplexed through TDM, since the SRS ports will be mapped to multiple symbols, if some of the symbols conflict with uplink resources, the transmission performance of the SRS will be affected.

In order to solve the problem of affecting SRS transmission performance when SRS conflicts with uplink resources when the SRS port is multiplexed using TD-OCC or TDM, as shown in Figure 2, an embodiment of the present application provides an SRS The method 200 for handling conflicts with uplink resources can be executed by a terminal. In other words, the method can be executed by software or hardware installed on the terminal. The method includes the following steps.

S202: In the case where the SRS conflicts with the uplink resources on N symbols, the terminal determines the sending mode of the SRS according to the first processing rule; wherein the port multiplexing mode of the SRS includes using a TD-SRS with a length of L OCC sequences are multiplexed, or TDM is used for multiplexing; the first processing rule includes at least one of the following: discarding D symbols among the SRS occupied symbols, where the D symbols include the N conflicting symbols. symbol; transmit all or part of the port of the SRS on S reserved symbols, which are symbols that have not been discarded among the SRS occupied symbols; N, L, D and S are positive integers.

The uplink resources mentioned in various embodiments of this application may include at least one of the following: other SRS (that is, 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 used to cancel or silence SRS transmission.

In the embodiment of the present application, when the SRS ports are multiplexed using TDM, the SRS ports can be mapped on different symbols. For example, as shown in Figure 3, SRS ports 0 to 3 are mapped on symbol # 1, ports 4 to 7 are mapped to symbol #2.

In this embodiment of the present application, the SRS occupied symbols may be the SRS occupied symbols in one time slot.

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

The conflict handling method between SRS and uplink resources provided by the embodiment of the present application, when the SRS port adopts TD-OCC sequence or TDM for multiplexing, if the SRS and uplink resources conflict on N symbols, the terminal The sending mode of the SRS may be determined according to a first processing rule, which includes at least one of the following: discarding D symbols among the SRS occupied symbols; sending all or part of the SRS on S reserved symbols. port. The embodiment of the present application defines the behavior of the terminal during conflict through the first processing rule, which is conducive to ensuring the performance of the terminal in transmitting SRS and improving Communication system performance.

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

1) Send all P ports of the SRS on the S reserved symbols, where P is a positive integer.

All P ports that transmit the SRS on the S reserved symbols satisfy at least one of the following conditions:

a. There is a third reserved symbol. The third reserved symbol is all the symbols of one or more symbol groups mapped by the TD-OCC sequence. The third reserved symbol belongs to the S reserved symbols. The symbol The group contains L symbols, which may be L symbols mapped by the TD-OCC sequence.

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

b. There is a fourth reserved symbol. On the fourth reserved symbol, the subsequences or combinations of subsequences corresponding to the P ports satisfy orthogonality, and the subsequences are subsequences of the TD-OCC sequence. sequence, the fourth reserved symbol belongs to the S reserved symbols.

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

2) Send X ports among all P ports of the SRS on the S reserved symbols, P and X are positive integers, and X<P.

The X ports among all P ports that transmit the SRS on the S reserved symbols satisfy one of the following conditions:

a. There are conflicting symbols in at least one symbol group mapped by the TD-OCC sequence. The symbol group contains L symbols. The L symbols may be L symbols mapped by the TD-OCC sequence.

b. There are conflicting symbols in each symbol group mapped by the TD-OCC sequence. The symbol group contains L symbols. The L symbols may be the L symbols mapped by the TD-OCC sequence.

3) All P ports of the SRS are sent on the first reserved symbol, and X ports of all P ports of the SRS are sent on the second reserved symbol. The first reserved symbol and the second The reserved symbols belong to the S reserved symbols; among them, P and X are positive integers, and X<P.

All P ports of the SRS are sent on the first reserved symbol, and X ports among all P ports of the SRS are sent on the second reserved symbol, and the following conditions are met: the first reserved symbol is All symbols of one or more symbol groups mapped by the TD-OCC sequence, there are no conflicting symbols in the one or more symbol groups, and the symbol group contains L symbols; the second reservation The symbols are partial symbols of one or more symbol groups mapped by the TD-OCC sequence. There are conflicting symbols in the one or more symbol groups, and the symbol group contains L symbols.

The above embodiments 1) to 3) propose processing rules suitable for TD-OCC to solve the conflict problem between SRS and uplink resources. SRS discarded on conflicting symbols will not affect the orthogonality of TD-OCC. Thereby ensuring the channel estimation performance of SRS.

The processing rules in 1) to 3) above are also applicable to the case where the SRS port is multiplexed using TDM. For example, SRS ports 0 to 3 are mapped to symbol #1, and ports 4 to 7 are mapped to symbol #2. If SRS and uplink resources conflict on symbol #1, you can discard ports 0 to 3 of the SRS on symbol #1, and only send ports 4 to 7 of the SRS on symbol #2 (reserved symbol), or you can discard the symbol Ports 0 to 7 of the SRS on #1 and symbol #2 are all ports of the SRS, and no symbols are reserved at this time.

In addition, when a conflict occurs, retaining some SRS ports for transmission can maximize the utilization of uplink transmission resources and the efficiency of uplink channel update.

Optionally, the X ports mentioned in the above embodiments are determined based on at least one of the following:

1) Network side device configuration or instructions.

2) Determined according to the first rule; wherein the first rule includes: the index of the X ports is the smallest or the index is the largest; or the index of the X ports is the first index, and the first index is the same as the TD-OCC sequence correlation; or, the index of the X ports is a second index, and the second index is related to the antenna correlation capability of the terminal. For example, the X ports have antenna correlation, that is, they belong to same related antenna port group.

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

3) Determined according to the second rule; wherein the second rule includes: the X ports are the X ports that change alternately among the all P ports, for example, they are the X ports that change alternately according to the index size among the all P ports. X ports.

The method provided in this embodiment further includes the following steps: the terminal enables or disables the alternation according to the configuration of the network side device, that is, the terminal can enable/disable the alternation according to the network side configuration.

In order to explain in detail the conflict handling method between SRS and uplink resources provided by the embodiments of the present application, the following will be described with reference to several specific embodiments.

Embodiment 1

This embodiment takes an SRS with a port number P of 8 as an example. As shown in Figure 4, the number of occupied symbols of the SRS is Ns=2, the number of repetitions of the SRS is R=2, and the 8 ports of the SRS are configured with a length of L=2. TD-OCC multiplexes on symbols #1 and #2. Among them, the TD-OCC sequence corresponding to ports 0 to 3 is [+1,+1], and the TD-OCC sequence corresponding to ports 4-7 is [+1,-1].

The terminal determines the SRS sending method according to the first processing rule, as follows:

1) When SRS and uplink resources conflict on N=1 symbols (taking the conflict on symbol #1 as an example), there are the following two processing methods:

a. The discarded symbol is symbol #1, which can be understood as discarding N=1 symbols that collide, or discarding K=1 symbols among the L=2 symbols of the TD-OCC mapped symbol group. The reserved symbol is symbol #2. On the reserved symbol #2, X=4 ports are sent, where X=4 ports can be determined according to the first rule as ports 0 to 3 (the X ports with the smallest index), or port 4 ~7 (X ports with the largest index). In addition, X=4 ports can also be alternately changed according to the second rule. For example, when the first conflict occurs, X=4 ports are ports 0 to 3 (the X ports with the smallest index). When the second conflict occurs subsequently, When , X=4 ports alternately change to ports 4 to 7 (the The advantage of this processing is that the network side can update the channels on all ports in time, thereby improving the overall channel estimation performance.

b. The discarded symbols are symbols #1 and #2, there are no reserved symbols, and symbol #2 is M=1 extra symbols discarded. At this time, it can also be understood that among the L=2 symbols (#1 and #2) of the TD-OCC mapped symbol group with length 2, there are N=1 conflicting symbols, so all L=2 symbols are discarded. symbol. At this time, all the symbols occupied by the SRS are discarded, so the SRS is not sent.

2) Similarly, when the SRS and uplink resources conflict on symbol #2: the discarded symbol is symbol #2 and the reserved symbol is symbol #1. Alternatively, symbols #1 and #2 are both discard symbols. The determination method of X ports is similar to 1) and will not be described again.

3) When SRS conflicts with uplink resources on symbols #1 and #2, that is, when the number of conflicting symbols is N=2: discard symbols #1 and #2, that is, discard all N=L=2 symbols. At this time, since all the symbols occupied by the SRS are discarded, the SRS is not sent.

Embodiment 2

This embodiment takes an SRS with a port number P of 8 as an example. As shown in Figure 5, the number of occupied symbols of the SRS is Ns=4, the number of repetitions of the SRS is R=2, and the 8 ports of the SRS use length L=2. TD-OCC multiplexes symbols #1 and #2, and symbols #3 and #4, that is, using the length L=2 of TD-OCC as the granularity, the Ns symbols occupied by SRS are divided into 2 based on TD - OCC symbol group. Among them, the TD-OCC sequence corresponding to ports 0 to 3 is [+1,+1], and the TD-OCC sequence corresponding to ports 4-7 is [+1,-1].

1) When SRS and uplink resources conflict on N=1 symbols, taking the conflict on symbol #1 as an example, there are the following three processing methods:

a. The discarded symbol is symbol #1, and the retained symbols are symbol #2, symbol #3, and symbol #4, that is, discarding K= of the L=2 symbols of the first symbol group (symbol #1 and symbol #2) 1 symbol, L=2 symbols of the second symbol group (symbol #3 and symbol #4) are retained. At this point, on reserved symbol #2 Send X=4 ports (the selection of 8 ports. It should be noted that at this time, reserved symbol #3 and reserved symbol #4 are the first reserved symbols, and reserved symbol #2 is the second reserved symbol.

b. The discarded symbol is symbol #1, and the retained symbols are symbol #2, symbol #3 and symbol #4, that is, discarding K= of the L=2 symbols of the first symbol group (symbol #1 and symbol #2) 1 symbol, L=2 symbols of the second symbol group (symbol #3 and symbol #4) are retained. At this time, all P=8 ports are transmitted on Reserved Symbol #2, Reserved Symbol #3, and Reserved Symbol #4. In this case, the reason why P=8 ports can be sent on reserved symbol #2 is because on reserved symbol #2 and reserved symbol #3, the combination of TD-OCC subsequences corresponding to the SRS ports satisfies orthogonality. property, that is, the combination of subsequences corresponding to ports 0 to 3 [+1, +1] and the combination of subsequences corresponding to ports 4 to 7 [-1, +1] are orthogonal to each other. It should be noted that at this time, reserved symbol #3 and reserved symbol #4 are the third reserved symbols, and reserved symbol #2 and reserved symbol #3 are the fourth reserved symbols.

c. The discarded symbols are symbol #1 and symbol #2, and the retained symbols are symbol #3 and symbol #4, that is, discarding all L = 2 symbols of the first symbol group (symbol #1 and symbol #2), symbol # 2 is an extra symbol discarded, and L=2 symbols of the second symbol group (symbol #3 and symbol #4) are retained. At this time, all P=8 ports are transmitted only on reserved symbol #3 and reserved symbol #4.

2) When SRS and uplink resources conflict on N=2 symbols, taking the conflict on symbol #1 and symbol #3 as an example, there are the following two processing methods:

a. The discarded symbols are symbol #1 and symbol #3, and the retained symbols are symbol #2 and symbol #4. Only X=4 ports are sent on reserved symbols. Among them, the X=4 ports on symbol #2 and symbol #4 are the same. For example, the X ports on symbol #2 and symbol #4 are both ports 0 to 3.

b. The discarded symbols are symbol #1 and symbol #3, and the retained symbols are symbol #2 and symbol #4. Only X=4 ports are sent on reserved symbols. Among them, 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 SRS and uplink resources conflict on N=2 symbols, taking the conflict on symbol #2 and symbol #3 as an example, there are the following three processing methods:
