[0117] The following describes and explains the terms involved in the present disclosure.

[0118] 1. Introduction to SRS:

[0119] In the NR system, SRS can be periodic, semi-persistent or aperiodic, narrowband or broadband, single-port or multi-port. In some embodiments, the parameters of SRS can be configured by the network device, for example, the number of ports, frequency domain resource location, time domain resource location, sequence, sequence cycle offset, etc. can be configured.

[0120] In some embodiments, SRS can be configured to be sent on multiple ports, for example, multiplexing can be performed by code division or frequency division, similar to the LTE system, and different phase shifts of the ZC (Zadoff-Chu) sequence can be used to obtain an orthogonal sequence for sending SRS. In addition, in the frequency domain, the mapping method of the spaced subcarriers can be used to obtain frequency domain orthogonality. In one embodiment, SRS can be mapped at intervals of one subcarrier or three subcarriers.

[0121] In some embodiments, one SRS resource may be mapped onto N consecutive orthogonal frequency division multiplexing (OFDM) symbols, where N=1, 2, or 4. Figure 1B FIG. 1 is a schematic diagram of SRS resources according to an embodiment of the present disclosure. Figure 1B As shown, SRS resource 1 occupies one OFDM symbol, SRS resource 2 occupies four OFDM symbols, and SRS resource 3 occupies two OFDM symbols. In one embodiment, one SRS resource occupies multiple OFDM symbols for two main purposes: 1) improving the coverage of the SRS reference signal; 2) supporting frequency hopping within a time slot. When the SRS frequency hopping function is enabled, one SRS resource occupies consecutive OFDM symbols within a time slot, but occupies different subbands in the frequency domain.

[0122] 2. Introduction to PUCCH:

[0123] In order to support the transmission of different bit ranges of uplink control information (UCI), from the perspective of bit number, two types of PUCCH are defined in the NR system. Among them, one type of PUCCH is a PUCCH format used to carry 1 to 2 bits of UCI transmission, and the other type of PUCCH is a PUCCH format used to carry more than 2 bits of UCI transmission. In addition, from the perspective of uplink coverage and transmission delay, two types of PUCCH are defined in the NR system, one type of PUCCH is a short PUCCH format, occupying 1 or 2 symbols, and the other type of PUCCH is a long PUCCH format, occupying 4 to 14 symbols. Combining the above two dimensions, 5 PUCCH formats are defined in the NR system, as shown in Table 1 below.

[0124] Table 1

[0125]

[0126] In some embodiments, the number of timeslot-level repetitions can be configured for PUCCH transmissions of formats 1, 3, and 4 through the parameter nrofSlots in the radio resource control (RRC) signaling, and PUCCH transmissions of formats 1, 3, and 4 can be repeatedly transmitted on the same symbol in multiple consecutive time slots. In one embodiment, the number of repetitions supported by PUCCH transmissions of formats 1, 3, and 4 is 1, 2, 4, and 8. In some embodiments, repeated transmission is not supported for PUCCH transmissions of formats 0 and 2.

[0127] In some embodiments, PUCCH transmissions of formats 2, 3, and 4 may carry periodic CSI reports, and the periodic CSI reports may support Type 1 CSI (Type I CSI) with wideband granularity.

[0128] In some embodiments, semi-persistent CSI reports may be carried in PUCCH transmissions of format 2, and semi-persistent CSI reports may support Type I CSI with wideband frequency granularity. In some embodiments, semi-persistent CSI reports may be carried in PUCCH transmissions of format 3 and format 4, and semi-persistent CSI reports may support Type I CSI with wideband and subband frequency granularity and the first part of Type 2 CSI (Type IICSI).

[0129] In some embodiments, semi-persistent CSI reporting carried in PUCCH transmissions of formats 3 and 4 supports Type IICSI, but only supports the first part of Type IICSI.

[0130] In some embodiments, when the terminal configures CSI reporting on PUCCH transmissions of format 2, format 3, and format 4, each PUCCH resource may be configured for each candidate uplink bandwidth part (ULBWP).

[0131] In some embodiments, when the terminal uses the configuration of PUCCH transmission of format 4, the terminal cannot report CSI whose total number of UCI bits and cyclic redundancy check (CRC) bits is greater than 115 bits.

[0132] In some embodiments, the terms "aperiodic", "aperiodic transmission", "aperiodic transmission" and the like are interchangeable. In some embodiments, the terms "semi-persistent", "semi-persistent transmission", "semi-persistent transmission" and the like are interchangeable. In some embodiments, the terms "periodic", "periodic transmission", "periodic transmission" and the like are interchangeable.

[0133] 3. Introduction to uplink transmission conflicts:

[0134] The uplink transmission may include SRS transmission and uplink channel transmission. In one embodiment, the uplink channel transmission may include PUCCH transmission and may also include a physical uplink share channel (PUSCH). Of course, the uplink channel may also be other channels that carry uplink signals, which is not specifically limited in the embodiments of the present disclosure.

[0135] In some embodiments, in a time slot, the time domain resources (such as one or more symbols) configured for SRS transmission may overlap with the time domain resources (such as one or more symbols) configured for PUCCH transmission. In this case, the SRS transmission and the PUCCH transmission conflict in the time domain, which can also be referred to as the SRS transmission and the PUCCH transmission colliding in the time domain. In the case that the SRS transmission and the PUCCH transmission conflict in the time domain, the terminal needs to handle the conflict according to the priority of the SRS transmission and the PUCCH transmission to determine the uplink transmission actually sent in the time slot where the conflict occurs, such as the SRS transmission or the PUCCH transmission, and the symbols occupied by the uplink transmission (i.e., the symbols actually sent by the terminal).

[0136] In some embodiments, the time domain resources configured for the above-mentioned SRS transmission overlap with the time domain resources configured for the PUCCH transmission, which can be understood as the SRS transmission being configured on the same symbol as the PUCCH transmission. At this time, one or more symbols in the time domain resources configured for the above-mentioned SRS transmission are the same as one or more symbols in the time domain resources configured for the PUCCH transmission. In this case, the same symbols in the time domain resources configured for the above-mentioned SRS transmission and the time domain resources configured for the PUCCH transmission can also be referred to as overlapping symbols (i.e., overlapping symbols), conflicting symbols (i.e., conflicting symbols), collision symbols (i.e., collision symbols), etc.

[0137] In some embodiments, in a time slot, a time domain resource (such as one or more symbols) configured for one SRS transmission may overlap with a time domain resource (such as one or more symbols) configured for another SRS transmission. In this case, a conflict occurs between the SRS transmissions, which may also be referred to as a collision between the SRS transmissions. In the event of a conflict between SRS transmissions, the terminal needs to process the conflict according to the priorities of different types of SRS transmissions to determine the SRS transmission actually sent in the time slot where the conflict occurs, such as a non-periodic SRS transmission, a semi-persistent SRS transmission, or a periodic SRS transmission, and the symbols occupied by the SRS transmission (i.e., the symbols actually sent by the terminal).

[0138] In some embodiments, the time domain resources configured for the above-mentioned one SRS transmission overlap with the time domain resources configured for another SRS transmission, which can be understood as one SRS transmission being configured on the same symbol as another SRS transmission. At this time, one or more symbols in the time domain resources configured for the above-mentioned one SRS transmission are the same as one or more symbols in the time domain resources configured for another SRS transmission. In this case, the same symbols in the time domain resources configured for the above-mentioned one SRS transmission and the time domain resources configured for another SRS transmission can also be referred to as overlapping symbols (i.e., overlapping symbols), conflicting symbols (i.e., conflicting symbols), collision symbols (i.e., collision symbols), etc.

[0139] In some embodiments, the time domain resources configured for SRS transmission or PUCCH transmission refer to a group of time domain resources (or resources) used to send SRS or PUCCH in a time slot configured by the network device, and can also be understood as a group of time domain resources occupied by the network device for sending SRS or PUCCH. This group of time domain resources may include one or more symbols in a time slot. Multiple symbols may be continuous.

[0140] In one embodiment, the conflict of uplink transmission may also be referred to as a time domain conflict of uplink transmission.

[0141] In some embodiments, multiple uplink transmissions may conflict in a time slot. In one example, 2 uplink transmissions in a time slot may conflict, 3 uplink transmissions in a time slot may conflict, 4 uplink transmissions in a time slot may conflict, and so on, N uplink transmissions in a time slot may conflict, in which case N≥2, where N is an integer.

[0142] In one embodiment, the uplink transmission conflict is described by taking the conflict of three uplink transmissions in the time domain as an example.

[0143] In one example, Figure 1C FIG. 1 is a schematic diagram showing three uplink transmission conflicts according to an embodiment of the present disclosure. Figure 1C As shown, the non-periodic SRS transmission, PUCCH transmission and periodic SRS transmission on the same carrier conflict. The time domain resources configured for the non-periodic SRS transmission overlap with the time domain resources configured for the PUCCH transmission, and the time domain resources configured for the PUCCH transmission overlap with the time domain resources configured for the periodic SRS transmission. The start time of the non-periodic SRS transmission is earlier than the start time of the conflict of the periodic SRS transmission.

[0144] In one example, Figure 1D FIG. 1 is another schematic diagram showing three uplink transmission conflicts according to an embodiment of the present disclosure. Figure 1D As shown, the non-periodic SRS transmission, PUCCH transmission and periodic SRS transmission on the same carrier conflict. The time domain resources configured for the non-periodic SRS transmission overlap with the time domain resources configured for the PUCCH transmission and the time domain resources configured for the periodic SRS transmission, respectively, and the time domain resources configured for the PUCCH transmission overlap with the time domain resources configured for the periodic SRS transmission. The start time of the non-periodic SRS transmission is earlier than the start time of the conflict of the periodic SRS transmission.

[0145] In one example, Figure 1E FIG. 1 is another schematic diagram showing three uplink transmission conflicts according to an embodiment of the present disclosure. Figure 1E As shown, the non-periodic SRS transmission, PUCCH transmission and periodic SRS transmission on the same carrier conflict. The time domain resources configured for the non-periodic SRS transmission overlap with the time domain resources configured for the PUCCH transmission and the time domain resources configured for the periodic SRS transmission, respectively, and the time domain resources configured for the PUCCH transmission overlap with the time domain resources configured for the periodic SRS transmission. The start time of the periodic SRS transmission is earlier than the start time of the conflict of the non-periodic SRS transmission.

[0146] In some embodiments, the PUCCH transmission in the above example may carry only CSI reports, only L1-RSRP reports, or only L1-SINR reports, wherein the CSI reports, L1-RSRP reports, and L1-SINR reports may be periodic, semi-persistent, or periodic.

[0147] It should be noted that the above is only an example of a conflict among N uplink transmissions in a time slot. There may also be other cases of uplink transmission conflicts, which are not specifically limited in the embodiments of the present disclosure.

[0148] 4. Introduction to SRS conflict handling:

[0149] In the NR system, SRS transmission is very flexible and can be configured at any one or more time domain symbol positions in a time slot. It is easy to conflict with other uplink channels / signals. Therefore, the transmission priority of uplink transmission when a conflict occurs is defined in the protocol.

[0150] In some embodiments, the conflict handling rules between SRS and PUCCH are as follows:

[0151] 1. For PUCCH and SRS on the same carrier, when semi-persistent or periodic SRS is configured in the same symbol as PUCCH carrying only CSI report, only L1-RSRP report or only L1-SINR report, the terminal does not send aperiodic, semi-persistent or periodic SRS.

[0152] 2. When semi-persistent or periodic SRS is configured or aperiodic SRS is triggered to be sent in the same symbol as the PUCCH carrying HARQ-ACK, link recovery request and / or SR, the terminal does not send semi-persistent or periodic SRS.

[0153] 3. When the aperiodic SRS is triggered to be transmitted in the same symbol as the PUCCH carrying only the semi-persistent or periodic CSI report, only the semi-persistent or periodic L1-RSRP report, or only the L1-SINR report, the terminal sends the above PUCCH.

[0154] 4. When the SRS is not transmitted due to overlap with the PUCCH, the terminal only drops the symbols configured with the SRS that overlap with the symbols configured with the PUCCH.

[0155] In some embodiments, in the above-mentioned conflict handling rules, the priorities of SRS and PUCCH are from high to low: PUCCH carrying HARQ-ACK, link recovery request and / or SR, non-periodic SRS, PUCCH carrying only CSI report, only L1-RSRP report or only L1-SINR report, semi-continuous SRS, and periodic SRS.

[0156] In some embodiments, the conflict handling rules for different types of SRS are as follows:

[0157] 1. When an SRS resource with the parameter "resourceType" set to "non-periodic" is triggered on an OFDM symbol configured with periodic or semi-persistent SRS, the terminal can transmit non-periodic SRS resources and only discard the symbols configured with periodic or semi-persistent SRS that overlap within the symbol, while still sending symbols configured with periodic or semi-persistent SRS that do not overlap with non-periodic SRS resources.

[0158] 2. When an SRS resource with the parameter "resourceType" set to "semi-persistent" is triggered on an OFDM symbol configured with periodic SRS, the terminal can send semi-persistent SRS resources and only discard symbols configured with periodic SRS that overlap within the symbol, while still sending symbols configured with periodic SRS that do not overlap with the semi-persistent SRS resources.

[0159] In some embodiments, in the above conflict handling rules, the priorities of different types of SRS are from high to low: non-periodic SRS, semi-persistent SRS, and periodic SRS.

[0160] In some embodiments, the terms "SRS" and "SRS transmission" can be used interchangeably. In some embodiments, the terms "SRS resource", "SRS time domain resource", "SRS symbol", "SRS configured time domain resource", and "SRS configured symbol" can be used interchangeably.

[0161] In some embodiments, the terms "PUCCH" and "PUCCH transmission" may be used interchangeably. In some embodiments, the terms "PUCCH resource", "PUCCH time domain resource", "PUCCH symbol", "PUCCH configured time domain resource", and "PUCCH configured symbol" may be used interchangeably.

[0162] In some embodiments, for the above Figure 1C to Figure 1EThe situation shown is that N (N≥3) uplink transmissions collide within a time slot. If the conflict is handled according to the above conflict handling rules, some conflict handling rules are not defined, which makes the behavior of the terminal uncertain in these situations, and further leads to inconsistent understanding of the actual sending behavior of the terminal by the network equipment.

[0163] In order to solve the above technical problems, an embodiment of the present disclosure provides a communication method. In the embodiment of the present disclosure, when the time domain resources configured for three or more (i.e., N≥3) uplink transmissions in a time slot overlap, the communication device can determine one or more uplink transmissions actually sent in the time slot and the symbols actually occupied by the uplink transmission according to the conflict processing order of these uplink transmissions, thereby realizing the processing of the uplink transmission conflict in the time domain.

[0164] Figure 2A 1 is a schematic diagram of a first flow chart of a communication method performed by a communication device according to an embodiment of the present disclosure. The communication method involved in the embodiment of the present disclosure can be applied to a communication device in a communication system 100. Figure 2A As shown, the communication method of the embodiment of the present disclosure includes steps S2101 to S2103.

[0165] In some embodiments, the communication device may be a terminal 101 or a network device 102 .

[0166] In some embodiments, the communication method involved in the embodiments of the present disclosure is described by taking the collision of three (ie, N=3) uplink transmissions in one time slot (eg, the first time slot) as an example.

[0167] It should be noted that the number of uplink transmissions that conflict within a time slot may be 4, 5, 6, or even more (ie, N>3). The conflict handling of these uplink transmissions can be referred to steps S2101 to S2102, and the embodiments of the present disclosure will not be elaborated here.

[0168] In step S2101, the conflict handling order of three uplink transmissions in one time slot is determined.

[0169] In some embodiments, when three uplink transmissions in a time slot collide, the communication device determines a collision handling order for the three uplink transmissions.

[0170] In some embodiments, the three uplink transmissions in one time slot are uplink transmissions on the same carrier. In one embodiment, the uplink transmission may include SRS transmission and uplink channel (such as PUCCH) transmission. In one embodiment, the SRS transmission may include non-periodic SRS transmission, semi-persistent SRS transmission, and periodic SRS transmission. In one embodiment, the PUCCH transmission may include at least one of PUCCH transmission in format 0, PUCCH transmission in format 1, PUCCH transmission in format 2, PUCCH transmission in format 3, and PUCCH transmission in format 4.

[0171] In some embodiments, the PUCCH transmission may carry only aperiodic, semi-persistent or periodic first information, and the first information may include one of a CSI report, an L1-RSRP report and an L1-RSRP report. In one example, the PUCCH transmission may carry only aperiodic, semi-persistent or periodic CSI report. In one example, the PUCCH transmission may carry only aperiodic, semi-persistent or periodic L1-RSRP report. In one example, the PUCCH transmission may carry only aperiodic, semi-persistent or periodic L1-SINR report.

[0172] In some embodiments, the conflict among three uplink transmissions in one time slot may include at least two of the conflicts among multiple SRS transmissions and the conflicts between SRS transmissions and PUCCH transmissions. In other words, in one time slot, the conflicting uplink transmissions may include at least three of multiple SRS transmissions and PUCCH transmissions. In one embodiment, in one time slot, a conflict occurs among multiple SRS transmissions, or a conflict occurs among multiple SRS transmissions and a conflict occurs between at least one SRS transmission and PUCCH transmission. In one embodiment, the two uplink transmissions associated with each conflict may be two SRS transmissions, or may be an SRS transmission and a PUCCH transmission.

[0173] In one embodiment, within a time slot, the overlap between the time domain resources configured for two uplink transmissions may include the overlap between the time domain resources configured for two SRS transmissions and the overlap between the time domain resources configured for SRS transmission and the time domain resources configured for PUCCH transmission.

[0174] In some embodiments, the communication device may determine the conflict handling order of three uplink transmissions in a time slot according to predefined information (such as protocol provisions). In one embodiment, the communication device determines the conflict handling order of every two uplink transmissions that conflict among the three uplink transmissions in a time slot according to the predefined information. Based on this, the communication device determines the conflict handling order of the three uplink transmissions in a time slot according to the predefined information, which reduces signaling interaction and saves system signaling overhead.

[0175] In one embodiment, the order of processing conflicts among the three uplink transmissions may be determined according to the order of the starting time when the time domain resources configured for the three uplink transmissions overlap. In one embodiment, the order of processing conflicts among the three uplink transmissions may be determined according to the order of the starting time when the conflicts among the three uplink transmissions occur. In one embodiment, the order of processing conflicts among the three uplink transmissions may be the order of the starting time when the time domain resources configured for the three uplink transmissions overlap.

[0176] In one example, see Figure 1C As shown, the non-periodic SRS transmission conflicts with the PUCCH transmission at time t1, and the starting time when the time domain resource transmission configured for the non-periodic SRS transmission and the time domain resource configured for the PUCCH transmission overlap is time t1.

[0177] The PUCCH transmission conflicts with the periodic SRS transmission at time t2, and the starting time when the time domain resource transmission configured by the PUCCH transmission overlaps with the time domain resource configured by the periodic SRS transmission is time t2. Since time t1 < time t2, the communication device can determine the conflict handling order of the non-periodic SRS transmission, PUCCH transmission and periodic SRS transmission according to the order of the overlapping starting times, which is the conflict between the non-periodic SRS transmission and the PUCCH transmission, and the conflict between the PUCCH transmission and the periodic SRS transmission.

[0178] In some embodiments, after the communication device determines the conflict handling order according to the order of the starting times of the overlap of the time domain resources configured for the three uplink transmissions, there are at least two uplink transmissions whose corresponding starting times of the overlap are the same. At this time, the communication device can further determine the conflict handling order of the at least two uplink transmissions according to the order of the uplink transmission priorities from low to high or the order of the uplink transmission priorities from high to low.

[0179] In one example, Figure 1D FIG. 1 is another schematic diagram showing an uplink transmission conflict according to an embodiment of the present disclosure. Figure 1DAs shown, the non-periodic SRS transmission conflicts with the PUCCH transmission at time t1, and the starting time when the time domain resource transmission configured by the non-periodic SRS transmission overlaps with the time domain resource configured by the PUCCH transmission is time t1. The non-periodic SRS transmission conflicts with the periodic SRS transmission at time t2, and the starting time when the time domain resource transmission configured by the non-periodic SRS transmission overlaps with the time domain resource configured by the periodic SRS transmission is time t2. The PUCCH transmission also conflicts with the periodic SRS transmission at time t2, and the starting time when the time domain resource transmission configured by the PUCCH transmission overlaps with the time domain resource configured by the periodic SRS transmission is still time t2. First, since time t1 < time t2, the communication device can determine to process the conflict between the non-periodic SRS transmission and the PUCCH transmission first according to the order of the starting time of the overlap. Then, the communication device may further determine the order of processing the conflict between the non-periodic SRS transmission and the periodic SRS transmission and the conflict between the PUCCH transmission and the periodic SRS transmission according to the order of priority from low to high or from high to low of the non-periodic SRS transmission, the PUCCH transmission uplink transmission and the periodic SRS transmission. If the order of priority is from low to high, the communication device may determine to process the conflict between the PUCCH transmission and the periodic SRS transmission first, and then process the conflict between the non-periodic SRS transmission and the periodic SRS transmission. At this time, the order of processing the conflict between the non-periodic SRS transmission, the PUCCH transmission and the periodic SRS transmission is: the conflict between the non-periodic SRS transmission and the PUCCH transmission, the conflict between the PUCCH transmission and the periodic SRS transmission, and the conflict between the non-periodic SRS transmission and the periodic SRS transmission. If the order of priority is from high to low, the communication device may determine to process the conflict between the non-periodic SRS transmission and the periodic SRS transmission first, and then process the conflict between the PUCCH transmission and the periodic SRS transmission. At this time, the conflict processing order of non-periodic SRS transmission, PUCCH transmission and periodic SRS transmission is: conflict between non-periodic SRS transmission and PUCCH transmission, conflict between non-periodic SRS transmission and periodic SRS transmission, conflict between PUCCH transmission and periodic SRS transmission.

[0180] In one example, Figure 1E FIG. 1 is another schematic diagram showing an uplink transmission conflict according to an embodiment of the present disclosure. Figure 1EAs shown, the periodic SRS transmission conflicts with the PUCCH transmission at time t1, and the starting time when the time domain resource transmission configured for the periodic SRS transmission overlaps with the time domain resource configured for the PUCCH transmission is time t1. The non-periodic SRS transmission conflicts with the periodic SRS transmission at time t2, and the starting time when the time domain resource transmission configured for the non-periodic SRS transmission overlaps with the time domain resource configured for the periodic SRS transmission is time t2. The PUCCH transmission also conflicts with the non-periodic SRS transmission at time t2, and the starting time when the time domain resource transmission configured for the PUCCH transmission overlaps with the time domain resource configured for the non-periodic SRS transmission is still time t2. First, since time t1 < time t2, the communication device can determine to process the conflict between the periodic SRS transmission and the PUCCH transmission first according to the order of the starting times of the overlap. Then, the communication device may further determine the order of processing the conflict between the non-periodic SRS transmission and the periodic SRS transmission and the conflict between the PUCCH transmission and the non-periodic SRS transmission according to the order of priority from low to high or from high to low of the non-periodic SRS transmission, the PUCCH transmission uplink transmission and the periodic SRS transmission. If the order of priority is from low to high, the communication device may determine to first process the conflict between the non-periodic SRS transmission and the periodic SRS transmission, and then process the conflict between the PUCCH transmission and the non-periodic SRS transmission. At this time, the order of processing the conflict between the non-periodic SRS transmission, the PUCCH transmission and the periodic SRS transmission is: the conflict between the periodic SRS transmission and the PUCCH transmission, the conflict between the non-periodic SRS transmission and the periodic SRS transmission, and the conflict between the PUCCH transmission and the non-periodic SRS transmission. If the order of priority is from high to low, the communication device may determine to first process the conflict between the non-periodic SRS transmission and the PUCCH, and then process the conflict between the non-periodic SRS transmission and the periodic SRS transmission. At this time, the conflict processing order of non-periodic SRS transmission, PUCCH transmission and periodic SRS transmission is: conflict between periodic SRS transmission and PUCCH transmission, conflict between non-periodic SRS transmission and PUCCH transmission, conflict between non-periodic SRS transmission and periodic SRS transmission.

[0181] In one embodiment, the conflict processing order of the three uplink transmissions may be determined in the order of the priorities of the uplink transmissions from low to high. In one embodiment, the conflict processing order of the three uplink transmissions may be determined in the order of the priorities of the three uplink transmissions from low to high.

[0182] In one example, see Figure 1CAs shown, the priorities of non-periodic SRS transmission, PUCCH transmission and periodic SRS transmission are from low to high: periodic SRS transmission, PUCCH transmission, non-periodic SRS transmission. Therefore, the communication device can determine the conflict handling order of non-periodic SRS transmission, PUCCH transmission and periodic SRS transmission in the order of priority from low to high, which is the conflict between periodic SRS transmission and PUCCH transmission, and the conflict between PUCCH transmission and non-periodic SRS transmission.

[0183] In one example, see Figure 1D As shown, the priorities of non-periodic SRS transmission, PUCCH transmission and periodic SRS transmission are from low to high: periodic SRS transmission, PUCCH transmission, non-periodic SRS transmission. Therefore, the communication device can determine the conflict handling order of non-periodic SRS transmission, PUCCH transmission and periodic SRS transmission in the order of priority from low to high, which is the conflict between periodic SRS transmission and PUCCH transmission, the conflict between periodic SRS transmission and non-periodic SRS transmission, and the conflict between PUCCH transmission and non-periodic SRS transmission.

[0184] In one example, see Figure 1E As shown, the priorities of non-periodic SRS transmission, PUCCH transmission and periodic SRS transmission are from low to high: periodic SRS transmission, PUCCH transmission, non-periodic SRS transmission. Therefore, the communication device can determine the conflict handling order of non-periodic SRS transmission, PUCCH transmission and periodic SRS transmission in the order of priority from low to high, which is the conflict between periodic SRS transmission and PUCCH transmission, the conflict between periodic SRS transmission and non-periodic SRS transmission, and the conflict between PUCCH transmission and non-periodic SRS transmission.

[0185] In one embodiment, the conflict processing order of the three uplink transmissions may be determined in descending order of the priorities of the uplink transmissions. In one embodiment, the conflict processing order of the three uplink transmissions may be determined in descending order of the priorities of the three uplink transmissions.

[0186] In one example, see Figure 1C As shown, the priorities of non-periodic SRS transmission, PUCCH transmission and periodic SRS transmission are as follows from high to low: non-periodic SRS transmission, PUCCH transmission, periodic SRS transmission. Therefore, the communication device can determine the conflict handling order of non-periodic SRS transmission, PUCCH transmission and periodic SRS transmission in the order of high to low priority: conflict between non-periodic SRS transmission and PUCCH transmission, conflict between PUCCH transmission and periodic SRS transmission.

[0187] In one example, see Figure 1D As shown, the priorities of non-periodic SRS transmission, PUCCH transmission and periodic SRS transmission are as follows from high to low: non-periodic SRS transmission, PUCCH transmission, periodic SRS transmission. Therefore, the communication device can determine the conflict handling order of non-periodic SRS transmission, PUCCH transmission and periodic SRS transmission in the order of high to low priority: conflict between non-periodic SRS transmission and PUCCH transmission, conflict between non-periodic SRS transmission and periodic SRS transmission, conflict between PUCCH transmission and periodic SRS transmission.

[0188] In one example, see Figure 1E As shown, the priorities of non-periodic SRS transmission, PUCCH transmission and periodic SRS transmission are as follows from high to low: non-periodic SRS transmission, PUCCH transmission, periodic SRS transmission. Therefore, the communication device can determine the conflict handling order of non-periodic SRS transmission, PUCCH transmission and periodic SRS transmission in the order of high to low priority: conflict between non-periodic SRS transmission and PUCCH transmission, conflict between non-periodic SRS transmission and periodic SRS transmission, conflict between PUCCH transmission and periodic SRS transmission.

[0189] It should be noted that, in the conflict handling process of N (N≥3) uplink transmissions, a certain conflict will disappear as other conflicts are handled, and at this time, the communication device can sequentially handle the next conflict. For example, according to the above conflict handling sequence, after handling the i-th conflict, the i+1-th conflict may no longer exist, and at this time, the communication device can sequentially handle the i+2-th conflict, i<=N-2, and i is a positive integer.

[0190] In step S2102, the uplink transmission actually sent in the time domain resources configured for two overlapping uplink transmissions and the symbols occupied by the uplink transmissions are determined in turn according to the conflict handling order.

[0191] In some embodiments, the communication device can handle the conflict between two overlapping uplink transmissions among three uplink transmissions in sequence according to the conflict handling order for a time slot (i.e., the first time slot) where the conflict occurs, thereby determining the uplink transmission actually sent in the time domain resources configured for the two uplink transmissions and the symbols occupied by the uplink transmissions.

[0192] In some embodiments, the order of conflict handling of the three uplink transmissions is determined according to the order of the starting moments of the overlap of the time domain resources configured for the three uplink transmissions. In this case, the communication device can handle the conflict between the two uplink transmissions in sequence according to the order of the starting moments of the overlap of the time domain resources configured for the three uplink transmissions to determine the uplink transmissions actually sent in the time domain resources configured for the two uplink transmissions and the symbols occupied by the uplink transmissions. In one embodiment, if the two uplink transmissions that conflict are different types of SRS transmissions, the communication device handles the conflict between the two uplink transmissions according to the priorities of the different types of SRS transmissions. In one embodiment, if the two uplink transmissions that conflict are SRS transmissions and PUCCH transmissions, the communication device handles the conflict between the two uplink transmissions according to the priorities of the different types of SRS transmissions and PUCCH transmissions.

[0193] In some embodiments, when the communication device processes the conflict between two uplink transmissions according to the priorities of different types of SRS transmissions, the conflict between the two SRS transmissions may be processed according to the conflict processing rules of different types of SRS transmissions. In one embodiment, when the communication device processes the conflict between the two SRS transmissions according to the above-mentioned conflict processing rules of different types of SRS transmissions, it may determine to send a high-priority SRS transmission on an overlapping symbol (such as a first symbol) in a time domain resource configured with a low-priority SRS transmission, and to send a low-priority SRS transmission on other symbols (such as a second symbol) in a time slot. In one embodiment, when the communication device processes the conflict between the two SRS transmissions according to the conflict processing rules of the same type of SRS transmissions, it may determine to discard the overlapping symbol (such as the first symbol) in the time domain resource configured with a low-priority SRS transmission.

[0194] In an example, the communication device may determine to send aperiodic or semi-persistent SRS transmissions on overlapping symbols in the time domain resources configured with periodic SRS transmissions, and to send periodic SRS transmissions on other symbols within a time slot.

[0195] In an example, the communication device may determine to send aperiodic SRS transmission on overlapping symbols in the time domain resources configured with semi-persistent SRS transmission, and to send semi-persistent SRS transmission on other symbols within a time slot.

[0196] In an example, the communication device may determine overlapping symbols in the time domain resource in which the SRS transmission of the drop period is configured.

[0197] In an example, the communication device may determine to discard overlapping symbols in the time domain resources configured for semi-persistent SRS transmission.

[0198] In one example, when an SRS resource with the parameter "resourceType" set to "non-periodic" is triggered on an OFDM symbol configured with a periodic or semi-persistent SRS, the communication device can transmit the non-periodic SRS resource and only discard the periodic or semi-persistent SRS configured symbols that overlap within the symbol, while still determining to send the periodic or semi-persistent SRS configured symbols that do not overlap with the non-periodic SRS resources.

[0199] In one example, when an SRS resource with the parameter "resourceType" set to "semi-persistent" is triggered on an OFDM symbol configured with periodic SRS, the communication device can send the semi-persistent SRS resource and only discard the symbols configured with periodic SRS that overlap within the symbol, while still determining to send symbols configured with periodic SRS that do not overlap with the semi-persistent SRS resource.

[0200] In some embodiments, when the communication device processes the conflict between two uplink transmissions according to the priority of SRS transmission and PUCCH transmission, the conflict between SRS transmission and PUCCH transmission may be processed according to the conflict processing rules of SRS transmission and PUCCH transmission. In one embodiment, when the communication device processes the conflict between SRS transmission and PUCCH transmission according to the conflict processing rules of SRS transmission and PUCCH transmission, it may determine to send the high-priority uplink transmission on the overlapping symbols (such as the first symbol) in the time domain resources configured with the high-priority uplink transmission, and to send the low-priority uplink transmission on other symbols (such as the second symbol) in a time slot. In one embodiment, when the communication device processes the conflict between SRS transmission and PUCCH transmission according to the conflict processing rules of SRS transmission and PUCCH transmission, it may determine to discard the overlapping symbols (such as the first symbol) in the time domain resources configured with the low-priority uplink transmission. In one embodiment, the length of the time domain resources configured for PUCCH transmission is greater than the length of the time domain resources configured for SRS transmission, then the time domain resources configured for SRS transmission overlap with the time domain resources configured for PUCCH transmission as a whole. If the priority of SRS transmission is lower than that of PUCCH transmission, the communication device may determine to discard the time domain resources configured for SRS transmission; if the priority of SRS transmission is higher than that of PUCCH transmission, the communication device may determine to discard the time domain resources configured for PUCCH transmission in a time slot.

[0201] In one example, the communication device may determine to send PUCCH transmission on overlapping symbols (such as the first symbol) in the time domain resources configured for PUCCH transmission, and to send semi-persistent or periodic SRS transmission on other symbols (such as the second symbol) in a time slot. At this time, PUCCH transmission carries only CSI report, only L1-RSRP report or only L1-SINR report; CSI report, only L1-RSRP report and only L1-SINR report may be periodic, non-periodic or semi-persistent.

[0202] In one example, the communication device may determine to send aperiodic SRS transmission on overlapping symbols (such as first symbols) in the time domain resources configured with aperiodic SRS transmission, and to send PUCCH transmission on other symbols (such as second symbols) in a time slot. At this time, PUCCH transmission carries only CSI report, only L1-RSRP report or only L1-SINR report; CSI report, only L1-RSRP report and only L1-SINR report may be periodic, aperiodic or semi-persistent.

[0203] In one example, when the time domain resources configured for SRS transmission overlap with the time domain resources configured for uplink channel transmission, it is determined not to send SRS transmission on the overlapping symbols, wherein the SRS transmission includes semi-continuous SRS transmission or periodic SRS transmission; the uplink channel transmission only, the first information includes at least one of the following: CSI report, L1-RSRP report, L1-SINR report; the first information is periodically sent, non-periodically sent or semi-continuously sent.

[0204] In one example, when the time domain resources configured for non-periodic SRS transmission overlap with the time domain resources configured for uplink channel transmission, it is determined not to send PUCCH transmission, wherein the uplink channel transmission carries first information, and the first information includes at least one of the following: CSI report, L1-RSRP report, L1-SINR report; the first information is sent periodically, non-periodically, or semi-continuously.

[0205] In some embodiments, the uplink channel transmission carrying the first information may be understood as the uplink channel parameter only carrying the first information.

[0206] In some embodiments, the PUCCH transmission may also carry at least one of HARQ-ACK, link recovery request and SR. At this time, the communication device may determine to send the PUCCH transmission on overlapping symbols (such as the first symbol) in the time domain resources configured for the PUCCH transmission, and to send non-periodic, semi-continuous or periodic SRS transmission on other symbols (such as the second symbol) within a time slot.

[0207] In one example, when the time domain resources configured for SRS transmission overlap with the time domain resources configured for uplink channel transmission (such as the second uplink transmission), it is determined not to send SRS transmission on the overlapping symbols, wherein the SRS transmission includes semi-continuous SRS transmission, periodic SRS transmission, and non-periodic SRS transmission, and the second uplink channel transmission carries second information, and the second information includes at least one of the following: HARQ-ACK, link recovery request, SR.

[0208] In one embodiment, in the case where it is determined not to send SRS transmission due to overlap, the communication device may determine to discard the overlapping symbols in the time domain resources configured for SRS transmission. In one embodiment, in the case where it is determined not to send SRS transmission on the overlapping symbols, the communication device may determine to discard the overlapping symbols in the time domain resources configured for SRS transmission.

[0209] In one example, for Figure 1C The conflict shown, Figure 3A FIG. 1 is a first schematic diagram of three uplink transmission conflict processing according to an embodiment of the present disclosure, wherein the dotted line represents the time domain resource of the discarded uplink transmission. Figure 3A As shown, the order of conflict handling of non-periodic SRS transmission, PUCCH transmission and periodic SRS transmission is conflict between non-periodic SRS transmission and PUCCH transmission, and conflict between PUCCH transmission and periodic SRS transmission. At this time, the communication device first handles the conflict between non-periodic SRS transmission and PUCCH transmission. According to the conflict handling rule between SRS transmission and PUCCH transmission, the communication device determines to send non-periodic SRS transmission on the time domain resources configured for non-periodic SRS transmission, and discards the time domain resources configured for PUCCH transmission in a time slot. Then, the communication device handles the conflict between PUCCH transmission and periodic SRS transmission. Since the time domain resources configured for PUCCH transmission in a time slot are discarded, the conflict between PUCCH transmission and periodic SRS transmission does not exist. Then, the communication device determines to send periodic SRS transmission on the time domain resources configured for periodic SRS transmission.

[0210] In one example, for Figure 1D The conflict shown, Figure 3B 3 is a second schematic diagram of processing three uplink transmission conflicts according to an embodiment of the present disclosure, wherein the dotted lines represent the discarded uplink transmission time domain resources and overlapping symbols. Figure 3BAs shown, the order of conflict processing of non-periodic SRS transmission, PUCCH transmission and periodic SRS transmission is conflict between non-periodic SRS transmission and PUCCH transmission, conflict between PUCCH transmission and periodic SRS transmission, and conflict between non-periodic SRS transmission and periodic SRS transmission. At this time, the communication device first processes the conflict between non-periodic SRS transmission and PUCCH transmission. According to the conflict processing rule between SRS transmission and PUCCH transmission, the communication device determines to send non-periodic SRS transmission on the time domain resources configured for non-periodic SRS transmission, and discards the time domain resources configured for PUCCH transmission in a time slot. Then, the communication device processes the conflict between PUCCH transmission and periodic SRS transmission. Since the time domain resources configured for PUCCH transmission in a time slot are discarded, the conflict between PUCCH transmission and periodic SRS transmission does not exist. At this time, the communication device continues to process the conflict between non-periodic SRS transmission and periodic SRS transmission. Then, the communication device determines to send non-periodic SRS transmission on the time domain resources configured with non-periodic SRS transmission according to the conflict handling rules for different types of SRS transmissions, and to send periodic SRS transmission on symbols (such as second symbols) other than overlapping symbols (such as first symbols) in the time domain resources configured with periodic SRS transmission.

[0211] In one example, for Figure 1D The conflict shown, see also Figure 3B As shown, the order of conflict handling of aperiodic SRS transmission, PUCCH transmission and periodic SRS transmission is conflict between aperiodic SRS transmission and PUCCH transmission, conflict between aperiodic SRS transmission and periodic SRS transmission, and conflict between PUCCH transmission and periodic SRS transmission. At this time, the communication device first handles the conflict between aperiodic SRS transmission and PUCCH transmission. According to the conflict handling rules between SRS transmission and PUCCH transmission, the communication device determines to send aperiodic SRS transmission on the time domain resources configured with aperiodic SRS transmission, and discards the time domain resources configured with PUCCH transmission in a time slot. Then, the communication device handles the conflict between aperiodic SRS transmission and periodic SRS transmission. At this time, according to the conflict handling rules for different types of SRS transmission, the communication device determines to send aperiodic SRS transmission on the time domain resources configured with aperiodic SRS transmission, and sends periodic SRS transmission on symbols (such as second symbols) other than overlapping symbols (such as first symbols) in the time domain resources configured with periodic SRS transmission. Next, the communication device processes the conflict between the PUCCH transmission and the periodic SRS transmission. Since the time domain resources configured for the PUCCH transmission in a time slot are discarded, the conflict between the PUCCH transmission and the periodic SRS transmission does not exist, and therefore, the communication device does not process it.

[0212] In one example, for Figure 1E The conflict shown, Figure 3C FIG. 1 is a third schematic diagram of three uplink transmission conflict processing according to an embodiment of the present disclosure, wherein the dotted line represents the time domain resource of the discarded uplink transmission. Figure 3C As shown, the order of conflict processing of non-periodic SRS transmission, PUCCH transmission and periodic SRS transmission is conflict between periodic SRS transmission and PUCCH transmission, conflict between non-periodic SRS transmission and periodic SRS transmission, and conflict between PUCCH transmission and non-periodic SRS transmission. At this time, the communication device first processes the conflict between periodic SRS transmission and PUCCH transmission. According to the conflict processing rule between SRS transmission and PUCCH transmission, the communication device determines to send PUCCH transmission on the time domain resources configured for PUCCH transmission, and discards the time domain resources configured for periodic SRS transmission. Then, the communication device processes the conflict between non-periodic SRS transmission and periodic SRS transmission. Since the time domain resources configured for periodic SRS transmission are discarded, the conflict between non-periodic SRS transmission and periodic SRS transmission does not exist. At this time, the communication device continues to process the conflict between PUCCH transmission and non-periodic SRS transmission. Then, the communication device determines to send the non-periodic SRS transmission on the time domain resources configured with the non-periodic SRS transmission according to the conflict handling rule between the SRS transmission and the PUCCH transmission, and discards the time domain resources configured with the PUCCH transmission in a time slot.

[0213] In one example, for Figure 1E The conflict shown, see also Figure 3C As shown, the order of conflict handling of non-periodic SRS transmission, PUCCH transmission and periodic SRS transmission is conflict between periodic SRS transmission and PUCCH transmission, conflict between non-periodic SRS transmission and PUCCH transmission, and conflict between non-periodic SRS transmission and periodic SRS transmission. At this time, the communication device first handles the conflict between periodic SRS transmission and PUCCH transmission. According to the conflict handling rule between SRS transmission and PUCCH transmission, the communication device determines to send PUCCH transmission on the time domain resources configured with PUCCH transmission, and discards the time domain resources configured with periodic SRS transmission. Then, the communication device handles the conflict between non-periodic SRS transmission and PUCCH transmission. At this time, according to the conflict handling rule between SRS transmission and PUCCH transmission, the communication device determines to send non-periodic SRS transmission on the time domain resources configured with non-periodic SRS transmission, and discards the time domain resources configured with PUCCH transmission in a time slot. Next, the communication device processes the conflict between the aperiodic SRS transmission and the periodic SRS transmission. Since the time domain resources configured for the periodic SRS transmission are discarded, there is no conflict between the aperiodic SRS transmission and the periodic SRS transmission. Therefore, the communication device does not process it.

[0214] In some embodiments, the order of conflict handling of the three uplink transmissions is determined in order of priority of the three uplink transmissions from low to high. In this case, the communication device can handle the conflict between the two uplink transmissions in order of priority of the three uplink transmissions from low to high, so as to determine the uplink transmission actually sent in the time domain resources configured for the two uplink transmissions and the symbols occupied by the uplink transmissions. In one embodiment, if the two uplink transmissions that conflict are different types of SRS transmissions, the communication device handles the conflict between the two uplink transmissions according to the priorities of the different types of SRS transmissions. In one embodiment, if the two uplink transmissions that conflict are SRS transmissions and PUCCH transmissions, the communication device handles the conflict between the two uplink transmissions according to the priorities of the different types of SRS transmissions and PUCCH transmissions.

[0215] In one example, for Figure 1C The conflict shown, Figure 4A FIG. 4 is a fourth schematic diagram of three uplink transmission conflict processing according to an embodiment of the present disclosure, wherein the dotted line represents the time domain resource of the discarded uplink transmission. Figure 4A As shown, the order of conflict handling of non-periodic SRS transmission, PUCCH transmission and periodic SRS transmission is conflict between periodic SRS transmission and PUCCH transmission, and conflict between PUCCH transmission and non-periodic SRS transmission. At this time, the communication device first handles the conflict between periodic SRS transmission and PUCCH transmission. According to the conflict handling rules between SRS transmission and PUCCH transmission, the communication device determines to send PUCCH transmission on the time domain resources configured with PUCCH transmission, and discards the time domain resources configured with periodic SRS transmission. Then, the communication device handles the conflict between PUCCH transmission and non-periodic SRS transmission. According to the conflict handling rules between SRS transmission and PUCCH transmission, the communication device determines to send non-periodic SRS transmission on the time domain resources configured with non-periodic SRS transmission, and discards the time domain resources configured with PUCCH transmission in a time slot.

[0216] In one example, for Figure 1D The conflict shown, Figure 4B FIG. 5 is a fifth schematic diagram of three uplink transmission conflict processing methods according to an embodiment of the present disclosure. Figure 4BAs shown, the order of conflict processing of non-periodic SRS transmission, PUCCH transmission and periodic SRS transmission is conflict between periodic SRS transmission and PUCCH transmission, conflict between periodic SRS transmission and non-periodic SRS transmission, and conflict between PUCCH transmission and non-periodic SRS transmission. At this time, the communication device first processes the conflict between periodic SRS transmission and PUCCH transmission. According to the conflict processing rule between SRS transmission and PUCCH transmission, the communication device determines to send PUCCH transmission on the time domain resource configured by PUCCH transmission, and discards the time domain resource configured by periodic SRS transmission. Then, the communication device processes the conflict between periodic SRS transmission and non-periodic SRS transmission. Since the time domain resource configured by periodic SRS transmission is discarded, the conflict between periodic SRS transmission and non-periodic SRS transmission does not exist. At this time, the communication device continues to process the conflict between PUCCH transmission and non-periodic SRS transmission. Then, according to the conflict handling rules between SRS transmission and PUCCH transmission, the communication device determines to send the non-periodic SRS transmission on the time domain resources configured with the non-periodic SRS transmission, and discards the time domain resources configured with the PUCCH transmission in a time slot.

[0217] In one example, for Figure 1E The conflict shown, Figure 4C FIG. 6 is a sixth schematic diagram of three uplink transmission conflict processing according to an embodiment of the present disclosure. Figure 4C As shown, the order of conflict processing of non-periodic SRS transmission, PUCCH transmission and periodic SRS transmission is: conflict between periodic SRS transmission and PUCCH transmission, conflict between periodic SRS transmission and non-periodic SRS transmission, conflict between PUCCH transmission and non-periodic SRS transmission. At this time, the communication device first processes the conflict between periodic SRS transmission and PUCCH transmission. According to the conflict processing rule between SRS transmission and PUCCH transmission, the communication device determines to send PUCCH transmission on the time domain resource configured by PUCCH transmission, and discards the time domain resource configured by periodic SRS transmission. Then, the communication device processes the conflict between periodic SRS transmission and non-periodic SRS transmission. Since the time domain resource configured by periodic SRS transmission is discarded, the conflict between periodic SRS transmission and non-periodic SRS transmission does not exist. At this time, the communication device continues to process the conflict between PUCCH transmission and non-periodic SRS transmission. Then, according to the conflict handling rules between SRS transmission and PUCCH transmission, the communication device determines to send the non-periodic SRS transmission on the time domain resources configured with the non-periodic SRS transmission, and discards the time domain resources configured with the PUCCH transmission in a time slot.

[0218] In some embodiments, the order of conflict handling of the three uplink transmissions is determined in descending order of the priorities of the three uplink transmissions. In this case, the communication device can handle the conflict between the two uplink transmissions in descending order of the priorities of the three uplink transmissions to determine the uplink transmission actually sent in the time domain resources configured for the two uplink transmissions and the symbols occupied by the uplink transmissions. In one embodiment, if the two uplink transmissions that conflict are different types of SRS transmissions, the communication device handles the conflict between the two uplink transmissions according to the priorities of the different types of SRS transmissions. In one embodiment, if the two uplink transmissions that conflict are SRS transmissions and PUCCH transmissions, the communication device handles the conflict between the two uplink transmissions according to the priorities of the different types of SRS transmissions and PUCCH transmissions.

[0219] In one example, for Figure 1C The conflict shown, see Figure 3A As shown, the order of conflict handling of non-periodic SRS transmission, PUCCH transmission and periodic SRS transmission is conflict between non-periodic SRS transmission and PUCCH transmission, and conflict between PUCCH transmission and periodic SRS transmission. At this time, the communication device first handles the conflict between non-periodic SRS transmission and PUCCH transmission. Then, according to the conflict handling rule between SRS transmission and PUCCH transmission, the communication device determines to send non-periodic SRS transmission on the time domain resources configured for non-periodic SRS transmission, and discards the time domain resources configured for PUCCH transmission in a time slot. Then, the communication device handles the conflict between PUCCH transmission and periodic SRS transmission. Since the time domain resources configured for PUCCH transmission are discarded, the conflict between PUCCH transmission and periodic SRS transmission does not exist. Then, the communication device determines to send periodic SRS transmission on the time domain resources configured for periodic SRS transmission.

[0220] In one example, for Figure 1D The conflict shown, see also Figure 3BAs shown, the order of conflict handling of aperiodic SRS transmission, PUCCH transmission and periodic SRS transmission is conflict between aperiodic SRS transmission and PUCCH transmission, conflict between aperiodic SRS transmission and periodic SRS transmission, and conflict between PUCCH transmission and periodic SRS transmission. At this time, the communication device first handles the conflict between aperiodic SRS transmission and PUCCH transmission. According to the conflict handling rules between SRS transmission and PUCCH transmission, the communication device determines to send aperiodic SRS transmission on the time domain resources configured with aperiodic SRS transmission, and discards the time domain resources configured with PUCCH transmission in a time slot. Then, the communication device handles the conflict between aperiodic SRS transmission and periodic SRS transmission. At this time, according to the conflict handling rules for different types of SRS transmission, the communication device determines to send aperiodic SRS transmission on the time domain resources configured with aperiodic SRS transmission, and sends periodic SRS transmission on symbols (such as second symbols) other than overlapping symbols (such as first symbols) in the time domain resources configured with periodic SRS transmission. Next, the communication device processes the conflict between the PUCCH transmission and the non-periodic SRS transmission. Since the time domain resources configured for the PUCCH transmission in a time slot are discarded, there is no conflict between the PUCCH transmission and the periodic SRS transmission. Therefore, the communication device does not process it.

[0221] In one example, for Figure 1E The conflict shown, Figure 5A FIG. 7 is a seventh schematic diagram of three uplink transmission conflict processing according to an embodiment of the present disclosure. Figure 5AAs shown, the order of conflict handling of aperiodic SRS transmission, PUCCH transmission and periodic SRS transmission is conflict between aperiodic SRS transmission and PUCCH transmission, conflict between aperiodic SRS transmission and periodic SRS transmission, and conflict between PUCCH transmission and periodic SRS transmission. At this time, the communication device first handles the conflict between aperiodic SRS transmission and PUCCH transmission. According to the conflict handling rules between SRS transmission and PUCCH transmission, the communication device determines to send aperiodic SRS transmission on the time domain resources configured with aperiodic SRS transmission, and discards the time domain resources configured with PUCCH transmission in a time slot. Then, the communication device handles the conflict between aperiodic SRS transmission and periodic SRS transmission. At this time, according to the conflict handling rules for different types of SRS transmission, the communication device determines to send aperiodic SRS transmission on the time domain resources configured with aperiodic SRS transmission, and sends periodic SRS transmission on symbols (such as second symbols) other than overlapping symbols (such as first symbols) in the time domain resources configured with periodic SRS transmission. Next, the communication device processes the conflict between the PUCCH transmission and the non-periodic SRS transmission. Since the time domain resources configured for the PUCCH transmission in a time slot are discarded, there is no conflict between the PUCCH transmission and the periodic SRS transmission. Therefore, the communication device does not process it.

[0222] In step S2103, the first uplink transmission sent in a time slot and the symbols occupied by the first uplink transmission are determined according to the uplink transmission actually sent and the symbols occupied by the uplink transmission.

[0223] In some embodiments, the first uplink transmission is an uplink transmission actually sent in a time slot where a conflict occurs. In one embodiment, the number of the first uplink transmission may be one or more.

[0224] In some embodiments, after the communication device has successively determined the uplink transmissions actually sent and the symbols occupied by the uplink transmissions in the time domain resources configured for the two conflicting uplink transmissions, it is able to determine the first uplink transmission actually sent and the symbols occupied by the first uplink transmission in a time slot where the conflict occurs by combining the results of the determination.

[0225] In one example, see Figure 3A As shown, the communication device determines to send a non-periodic SRS transmission on a time domain resource configured for a non-periodic SRS transmission, and determines to send a periodic SRS transmission on a time domain resource configured for a periodic SRS transmission. In this case, the first uplink transmission includes the non-periodic SRS transmission and the periodic SRS transmission, and the symbols occupied by the first uplink transmission include the time domain resources configured for the non-periodic SRS transmission and the time domain resources configured for the periodic SRS transmission.

[0226] In one example, see Figure 3B as well as Figure 5A As shown, the communication device determines to send a non-periodic SRS transmission on the time domain resources configured for the non-periodic SRS transmission, and to send a periodic SRS transmission on symbols (such as the second symbol) other than overlapping symbols (such as the first symbol) in the time domain resources configured for the periodic SRS transmission. In this case, the first uplink transmission includes the non-periodic SRS transmission and the periodic SRS transmission, and the symbols occupied by the first uplink transmission include the time domain resources configured for the non-periodic SRS transmission and the symbols other than overlapping symbols in the time domain resources configured for the periodic SRS transmission.

[0227] In one example, see Figure 3C , Figure 4A , Figure 4B as well as Figure 4C As shown, the communication device determines to send aperiodic SRS transmission on the time domain resources configured for aperiodic SRS transmission. In this case, the first uplink transmission includes the aperiodic SRS transmission, and the symbols occupied by the first uplink transmission include the time domain resources configured for the aperiodic SRS transmission.

[0228] In some embodiments, PUCCH transmission may be configured with multiple time slots, which include a time slot where a conflict occurs. In one embodiment, if the first uplink transmission sent by the communication device in a time slot in which a conflict is determined to occur does not include PUCCH transmission, in other words, the communication device determines not to send PUCCH transmission in a time slot in which a conflict occurs, the communication device may determine to send PUCCH transmission in other time slots in the multiple time slots except the time slot in which a conflict occurs. In one embodiment, if the first uplink transmission sent by the communication device in a time slot in which a conflict is determined to occur does not include PUCCH transmission, in other words, the communication device determines not to send PUCCH transmission in a time slot in which a conflict occurs, the communication device may determine not to send PUCCH transmission in multiple time slots.

[0229] In some embodiments, when the communication device is a terminal, after determining the first uplink transmission sent in a time slot where a conflict occurs and the symbol occupied by the first uplink transmission through steps S2101 to S2103, the terminal can send the first uplink transmission to the network device on the symbol occupied by the first uplink transmission.

[0230] In some embodiments, when the communication device is a network device, after the network device determines the first uplink transmission sent by the terminal in a time slot where a conflict occurs and the symbol occupied by the first uplink transmission through steps S2101 to S2103, the network device can receive the first uplink transmission sent by the terminal on the symbol occupied by the first uplink transmission.

[0231] In some embodiments, the above Figure 1C to Figure 1E In the conflict shown, the periodic SRS transmission can be replaced by a semi-persistent SRS transmission. FIG. 3A to FIG. 3C , FIG. 4A to FIG. 4C as well as Figure 5A In the example shown, periodic SRS transmission may be replaced with semi-persistent SRS transmission.

[0232] In some embodiments, the number of uplink transmissions that collide in a time slot (such as the first time slot) may be greater than 3 (i.e., N>3), such as 4 uplink transmissions that collide, 5 uplink transmissions that collide, etc. In one embodiment, when N>3, the communication device may refer to the conflict handling process of 3 uplink transmissions in steps S2101 to S2103 to perform conflict handling on the situations of 4 uplink transmissions that collide, 5 uplink transmissions that collide, etc.

[0233] In one example, a case where four uplink transmissions collide is used as an example for explanation.

[0234] Figure 1F FIG. 4 is a schematic diagram showing four uplink transmission conflicts according to an embodiment of the present disclosure. Figure 1F As shown, the non-periodic SRS transmission, PUCCH transmission, periodic SRS transmission and semi-persistent SRS transmission on the same carrier conflict. Among them, the time domain resources configured for the non-periodic SRS transmission overlap with the time domain resources configured for the PUCCH transmission, the time domain resources configured for the non-periodic SRS transmission overlap with the time domain resources configured for the periodic SRS transmission, the time domain resources configured for the PUCCH transmission overlap with the time domain resources configured for the periodic SRS transmission, and the time domain resources configured for the PUCCH transmission overlap with the time domain resources configured for the semi-persistent SRS transmission. The starting time of the non-periodic SRS transmission is earlier than the starting time of the periodic SRS transmission, and the starting time of the periodic SRS transmission is earlier than the starting time of the semi-persistent SRS transmission.

[0235] In this case, first, referring to step S2101, the non-periodic SRS transmission collides with the PUCCH transmission at time t1, and the starting time when the time domain resource transmission configured by the non-periodic SRS transmission overlaps with the time domain resource configured by the PUCCH transmission is time t1. The non-periodic SRS transmission collides with the periodic SRS transmission at time t2, and the starting time when the time domain resource transmission configured by the non-periodic SRS transmission overlaps with the time domain resource configured by the periodic SRS transmission is time t2. The PUCCH transmission also collides with the periodic SRS transmission at time t2, and the starting time when the time domain resource transmission configured by the PUCCH transmission overlaps with the time domain resource configured by the periodic SRS transmission is still time t2. The PUCCH transmission collides with the semi-persistent SRS transmission at time t4, and the starting time when the time domain resource transmission configured by the PUCCH transmission overlaps with the time domain resource configured by the semi-persistent SRS transmission is time t4. First, since time t1 < time t2, the communication device can determine to process the conflict between the non-periodic SRS transmission and the PUCCH transmission first according to the order of the starting time of the overlap. Then, the communication device can further determine to process the conflict between the PUCCH transmission and the periodic SRS transmission first, and then process the conflict between the non-periodic SRS transmission and the periodic SRS transmission according to the order of the priority of the non-periodic SRS transmission, the PUCCH transmission uplink transmission and the periodic SRS transmission from low to high. Next, since time t2 < time t4, the communication device can determine to process the conflict between the PUCCH transmission and the semi-persistent SRS transmission according to the order of the starting time of the overlap. At this time, the conflict processing order of the non-periodic SRS transmission, the PUCCH transmission, the periodic SRS transmission and the semi-persistent SRS transmission is: the conflict between the non-periodic SRS transmission and the PUCCH transmission, the conflict between the PUCCH transmission and the periodic SRS transmission, the conflict between the non-periodic SRS transmission and the periodic SRS transmission, and the conflict between the PUCCH transmission and the semi-persistent SRS transmission.

[0236] Then, referring to step S2102, Figure 3D 4 is a first schematic diagram of processing four uplink transmission conflicts according to an embodiment of the present disclosure, wherein the dotted lines represent the discarded uplink transmission time domain resources and overlapping symbols. Figure 3DAs shown, the order of conflict processing of non-periodic SRS transmission, PUCCH transmission, periodic SRS transmission and semi-persistent SRS transmission is conflict between non-periodic SRS transmission and PUCCH transmission, conflict between PUCCH transmission and periodic SRS transmission, conflict between non-periodic SRS transmission and periodic SRS transmission, and conflict between PUCCH transmission and semi-persistent SRS transmission. At this time, the communication device first processes the conflict between non-periodic SRS transmission and PUCCH transmission. According to the conflict processing rule between SRS transmission and PUCCH transmission, the communication device determines to send non-periodic SRS transmission on the time domain resource configured for non-periodic SRS transmission, and discards the time domain resource configured for PUCCH transmission in a time slot. Then, the communication device processes the conflict between PUCCH transmission and periodic SRS transmission. Since the time domain resource configured for PUCCH transmission in a time slot is discarded, the conflict between PUCCH transmission and periodic SRS transmission does not exist. At this time, the communication device continues to process the conflict between non-periodic SRS transmission and periodic SRS transmission. Then, the communication device determines to send non-periodic SRS transmission on the time domain resources configured for non-periodic SRS transmission and to send periodic SRS transmission on symbols (such as second symbols) other than overlapping symbols (such as first symbols) in the time domain resources configured for periodic SRS transmission according to the conflict handling rules for different types of SRS transmission. Next, the communication device continues to handle the conflict between PUCCH transmission and semi-persistent SRS transmission. Since the time domain resources configured for PUCCH transmission in a time slot are discarded, the conflict between PUCCH transmission and semi-persistent SRS transmission does not exist. At this time, the communication device determines to send semi-persistent SRS transmission on the time domain resources configured for semi-persistent SRS transmission.

[0237] Next, see step S2103, see Figure 3D As shown, the communication device determines to send aperiodic SRS transmission on the time domain resources configured for aperiodic SRS transmission, to send periodic SRS transmission on symbols other than overlapping symbols in the time domain resources configured for periodic SRS transmission, and to send semi-persistent SRS transmission on symbols other than overlapping symbols in the time domain resources configured for semi-persistent SRS transmission. In this case, the first uplink transmission includes aperiodic SRS transmission, periodic SRS transmission, and semi-persistent SRS transmission, and the symbols occupied by the first uplink transmission include the time domain resources configured for aperiodic SRS transmission, symbols other than overlapping symbols in the time domain resources configured for periodic SRS transmission, and the time domain resources configured for semi-persistent SRS transmission.

[0238] It should be noted that the above is only an example of a conflict between four uplink transmissions. There may be other situations where four uplink transmissions conflict, and the embodiments of the present disclosure do not specifically limit this. In some embodiments, for other situations where four uplink transmissions conflict, the conflict handling order and conflict handling rules described above may be referred to for conflict handling.

[0239] At this point, the conflict handling of uplink transmission is completed.

The communication method involved in the embodiment of the present disclosure can be applied to a communication device in a communication system 100, such as a terminal 101 or a network device 102. Fig. 6A As shown, the communication method of the embodiment of the present disclosure includes step S6101.

[0255] In step S6101, a first uplink transmission sent in a first time slot and symbols occupied by the first uplink transmission are determined according to a conflict handling order of N uplink transmissions on the same carrier.

[0256] In some embodiments, the time domain resources configured for the N uplink transmissions overlap in the first time slot.

[0257] In some embodiments, the N uplink transmissions include at least three of a plurality of SRS transmissions and uplink channel transmissions.

[0258] For optional implementations of step S6101, see Figure 2A Optional implementations of steps S2101 to S2103, and Figure 2A Other related parts in the embodiments involved will not be described in detail here.

[0259] In the following, the technical solution of the embodiment of the present disclosure is exemplarily described through specific implementation methods.

[0260] In some embodiments, according to the conflict discarding rules defined in the current protocol, some resource conflict situations have no corresponding definitions, which may lead to uncertainty in UE processing and ambiguity in the network side's understanding of the actual transmission of the terminal. Figure 1C to Figure 1E In the case shown, different rules are applied, and the terminal may need to send aperiodic SRS (AP-SRS) and periodic SRS (P-SRS), or the terminal may only send AP-SRS. It can be seen that the existing protocol needs to define the terminal behavior for the above situation to avoid inconsistent understanding between the terminal and the network.

[0261] In some embodiments, this solution is mainly used to define a sending method after a resource conflict occurs between SRS and PUCCH, as follows:

[0262] In one embodiment, when a PUCCH (such as the first information) carrying CSI / L1-RSRP / L1-SINR configured on the same carrier of the UE overlaps with at least one SRS resource, it is processed in the following manner:

[0263] Method 1: Apply them in the order of the timeline when the conflicts occur according to the priority principle currently defined in the protocol.

[0264] In one example, for Figure 1C In the case shown, that is, at time t1>t2, the conflict between the non-periodic SRS (AP-SRS) and the PUCCH is processed first, and the PUCCH is discarded. Then, there is no need to process the conflict at time t2, and the periodic SRS (P-SRS) can still be sent at time t2, as shown in FIG. Figure 3A shown.

[0265] In one example, for Figure 1D In the case shown, that is, at time t1>t2, the conflict between the non-periodic SRS (AP-SRS) and the PUCCH is processed first, and the PUCCH is discarded. Then, the conflict between the non-periodic SRS (AP-SRS) and the periodic SRS (P-SRS) is processed, and the overlapping symbols of the periodic SRS (P-SRS) are discarded. The periodic SRS (P-SRS) can be sent at time t3, as shown in FIG. Figure 3B shown.

[0266] In one example, for Figure 1EFor the situation shown, i.e., at the moment when t1 > t2, first handle the conflict between the SRS (P-SRS) in the periodic process and the PUCCH. The P-SRS will be discarded. Then handle the conflict between the aperiodic SRS (AP-SRS) and the PUCCH, and the PUCCH will be discarded, as Figure 3C .

[0267] Method 2: For multiple conflicting resources, first make a judgment and handle the resource conflicts starting from the resource conflicts corresponding to the resources with lower priorities according to the existing protocol priority rules, and then handle the conflicts of resource overlaps in sequence.

[0268] In an example, for Figure 1C to Figure 1E the situation shown, first perform a priority sorting, which is P-SRS < PUCCH(CSI) < AP-SRS (that is, the priority of P-SRS is lower than the priority of PUCCH (including CSI reports), and the priority of PUCCH (including CSI reports) is lower than the priority of AP-SRS). In this way, first handle the overlap problem between P-SRS and PUCCH, then the P-SRS will not be sent. Then judge the conflict between AP-SRS and PUCCH, and the PUCCH will not be sent. Therefore, actually only the AP-SRS is sent, as FIG. 4A to FIG. 4C shown.

[0269] Method 3: For multiple conflicting resources, first make a judgment and handle the resource conflicts starting from the resource conflicts corresponding to the resources with higher priorities according to the existing protocol priority rules, and then handle the conflicts of resource overlaps in sequence.

[0270] In an example, for Figure 1C the situation shown, first perform a priority sorting, which is AP-SRS > PUCCH(CSI) > P-SRS (that is, the priority of AP-SRS is higher than the priority of PUCCH (including CSI reports), and the priority of PUCCH (including CSI reports) is higher than the priority of P-SRS). In this way, first handle the overlap problem between AP-SRS and PUCCH, then the PUCCH will not be sent. Since the P-SRS does not conflict with the AP-SRS, it can be sent. Therefore, actually the P-SRS and the AP-SRS are sent, as Figure 3A shown.

[0271] In an example, for Figure 1D and 1EIn the case shown, the priority will be sorted as AP-SRS>PUCCH(CSI)>P-SRS (i.e., the priority of AP-SRS is higher than the priority of PUCCH (including CSI report), and the priority of PUCCH (including CSI report) is higher than the priority of P-SRS). In this way, the overlap problem between AP-SRS and PUCCH is handled first, and PUCCH is not sent. Then, the conflict between the non-periodic SRS (AP-SRS) and the periodic SRS (P-SRS) is handled, and the overlapping symbols of the periodic SRS (P-SRS) are discarded, and the periodic SRS (P-SRS) is sent at time t3, as shown in FIG. Figure 3B and 5A shown.
