[0118] The following explains and interprets the terms related to the present disclosure.

[0119] I. Introduction to SRS

[0120] In the NR system, SRS can be periodic, semi-persistent or aperiodic, narrowband or wideband, single-port or multi-port. In some embodiments, the parameters of SRS can be configured by the network device, such as the number of ports, frequency domain resource location, time domain resource location, sequence, sequence cyclic shift, etc.

[0121] In some embodiments, SRS can be configured to be sent on multiple ports, for example, multiplexing can be performed in a code division or frequency division manner. Similar to the LTE system, different phase shifts of ZC (Zadoff-Chu) sequences can be used to obtain orthogonal sequences for sending SRS. In addition, in the frequency domain, mapping of interval subcarriers can be used to obtain frequency domain orthogonality. In an embodiment, SRS can be mapped at an interval of one subcarrier or an interval of three subcarriers.

[0122] In some embodiments, one SRS resource can be mapped on N consecutive OFDM (orthogonal frequency division multiplexing) symbols, N = 1, 2, 4. FIG. IB is a schematic diagram of an SRS resource according to an embodiment of the present disclosure. As shown in FIG. IB, SRS resource 1 occupies one OFDM symbol, SRS resource 2 occupies 4 OFDM symbols, and SRS resource 3 occupies 2 OFDM symbols. In an embodiment, one SRS resource occupies multiple OFDM symbols for two main purposes: 1) to improve the coverage of SRS reference signals; 2) to support intra-slot frequency hopping. When the SRS frequency hopping function is enabled, one SRS resource occupies consecutive OFDM symbols in one slot, but occupies different subbands in the frequency domain.

[0123] II. Introduction to PUCCH

[0124] To support the transmission of different ranges of bit numbers of uplink control information (UCI), two categories of PUCCH are defined in the NR system from the perspective of bit numbers. One category of PUCCH is a PUCCH format used for carrying UCI transmission of 1 to 2 bits, and the other category of PUCCH is a PUCCH format used for carrying UCI transmission of more than 2 bits. In addition, from the perspective of uplink coverage and transmission delay, two categories of PUCCH are defined in the NR system, one category of PUCCH is a short PUCCH format occupying 1 or 2 symbols, and the other category of PUCCH is a long PUCCH format occupying 4 to 14 symbols. In combination with the above two dimensions, five PUCCH formats are defined in the NR system, as shown in Table 1 below.

[0125] Table 1

[0126] In some embodiments, the PUCCH transmission of formats 1, 3 and 4 can be configured with the number of times of slot-level repetition by the parameter nrofSlots in the radio resource control (RRC) signaling, and the PUCCH transmission of formats 1, 3 and 4 can be repeatedly transmitted on the same symbol in multiple consecutive slots. In an embodiment, the PUCCH transmission of formats 1, 3 and 4 supports the number of times of repetition of 1, 2, 4 and 8. In some embodiments, the PUCCH transmission of formats 0 and 2 does not support repeated transmission.

[0127] In some embodiments, the PUCCH transmission of formats 2, 3 and 4 can carry periodic CSI reports, and the periodic CSI reports can support Type I CSI with wideband granularity.

[0128] In some embodiments, the PUCCH transmission of format 2 can carry semi-persistent CSI reports, and the semi-persistent CSI reports can support Type I CSI with wideband frequency granularity. In some embodiments, the PUCCH transmission of formats 3 and 4 can carry semi-persistent CSI reports, and the semi-persistent CSI reports can support Type I CSI with wideband and sub-band frequency granularity and the first part of Type II CSI.

[0129] In some embodiments, the semi-persistent CSI reports carried in the PUCCH transmission of formats 3 and 4 support Type II CSI, but only support the first part of Type II CSI.

[0130] In some embodiments, when the terminal is configured to report CSI on PUCCH transmission in format 2, format 3 and format 4, each PUCCH resource can be configured to each candidate uplink bandwidth part (UL BWP).

[0131] In some embodiments, when the terminal uses the configuration of PUCCH transmission in 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", "non-periodically transmitted", "non-periodically transmitted" and the like can be replaced with each other. In some embodiments, the terms "semi-persistent", "semi-persistent transmitted", "semi-persistent transmitted" and the like can be replaced with each other. In some embodiments, the terms "periodic", "periodically transmitted", "periodically transmitted" and the like can be replaced with each other.

[0133] III. Introduction to uplink transmission conflict:

[0134] The uplink transmission can include SRS transmission and uplink channel transmission. In an embodiment, the uplink channel transmission can include PUCCH transmission, and can also include physical uplink shared channel (PUSCH). Of course, the uplink channel can also be other channels that carry uplink signals, and the embodiments of the present disclosure do not make specific limitations thereto.

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

[0136] In some embodiments, the time-domain resources configured for the SRS transmission overlap with the time-domain resources configured for the PUCCH transmission, which can be understood as the SRS transmission is configured on the same symbol as the PUCCH transmission. At this time, one or more symbols in the time-domain resources configured for the 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 SRS transmission and the time-domain resources configured for the PUCCH transmission can also be referred to as overlapping symbols (i.e., symbols that overlap), conflicting symbols (i.e., symbols that conflict), colliding symbols (i.e., symbols that collide), and the like.

[0137] In some embodiments, the time-domain resources configured for one SRS transmission (e.g., one or more symbols) can overlap with the time-domain resources configured for another SRS transmission within a slot, at which time the SRS transmissions conflict, which can also be referred to as the SRS transmissions colliding. In the case of the SRS transmissions conflicting, the terminal needs to handle the conflict according to the priority of different types of SRS transmissions to determine the SRS transmission (e.g., an aperiodic SRS transmission, a semi-persistent SRS transmission, or a periodic SRS transmission) actually transmitted within the slot in which the conflict occurs and the symbol (i.e., the symbol actually transmitted by the terminal) occupied by the SRS transmission.

[0138] In some embodiments, the time-domain resources configured for one SRS transmission overlap with the time-domain resources configured for another SRS transmission, which can be understood as the one SRS transmission is configured on the same symbol as the other SRS transmission. At this time, one or more symbols in the time-domain resources configured for the one SRS transmission are the same as one or more symbols in the time-domain resources configured for the other SRS transmission. In this case, the same symbols in the time-domain resources configured for the one SRS transmission and the time-domain resources configured for the other SRS transmission can also be referred to as overlapping symbols (i.e., symbols that overlap), conflicting symbols (i.e., symbols that conflict), colliding symbols (i.e., symbols that collide), and the like.

[0139] In some embodiments, the time-domain resources configured for the SRS transmission or the PUCCH transmission refer to a set of time-domain resources (or resources) configured by the network device for transmitting the SRS or the PUCCH within a slot, which can also be understood as a set of time-domain resources occupied by the network device for transmitting the SRS or the PUCCH. The set of time-domain resources can include one or more symbols within a slot. The multiple symbols can be consecutive.

[0140] In an embodiment, the conflict of uplink transmissions can also be referred to as the time-domain conflict of uplink transmissions.

[0141] In some embodiments, in a time slot, there can be multiple uplink transmission collision cases. In an example, 2 uplink transmissions in a time slot can collide, 3 uplink transmissions in a time slot can collide, 4 uplink transmissions in a time slot can collide, and so on, N uplink transmissions in a time slot can collide, where N≥2, and N is an integer.

[0142] In an embodiment, 3 uplink transmissions in a time slot are taken as an example to illustrate uplink transmission collision.

[0143] In an example, FIG. 1C is a schematic diagram of 3 uplink transmission collision according to an embodiment of the present disclosure. As shown in FIG. 1C, the aperiodic SRS transmission, the PUCCH transmission and the periodic SRS transmission on the same carrier collide. Among them, the time domain resource configured for the aperiodic SRS transmission overlaps with the time domain resource configured for the PUCCH transmission, and the time domain resource configured for the PUCCH transmission overlaps with the time domain resource configured for the periodic SRS transmission. The starting time of the aperiodic SRS transmission is earlier than the starting time of the collision of the periodic SRS transmission.

[0144] In an example, FIG. 1D is another schematic diagram of 3 uplink transmission collision according to an embodiment of the present disclosure. As shown in FIG. 1D, the aperiodic SRS transmission, the PUCCH transmission and the periodic SRS transmission on the same carrier collide. Among them, the time domain resource configured for the aperiodic SRS transmission respectively overlaps with the time domain resource configured for the PUCCH transmission and the time domain resource configured for the periodic SRS transmission, and the time domain resource configured for the PUCCH transmission overlaps with the time domain resource configured for the periodic SRS transmission. The starting time of the aperiodic SRS transmission is earlier than the starting time of the collision of the periodic SRS transmission.

[0145] In an example, FIG. 1E is still another schematic diagram of 3 uplink transmission collision according to an embodiment of the present disclosure. As shown in FIG. 1E, the aperiodic SRS transmission, the PUCCH transmission and the periodic SRS transmission on the same carrier collide. Among them, the time domain resource configured for the aperiodic SRS transmission respectively overlaps with the time domain resource configured for the PUCCH transmission and the time domain resource configured for the periodic SRS transmission, and the time domain resource configured for the PUCCH transmission overlaps with the time domain resource configured for the periodic SRS transmission. The starting time of the periodic SRS transmission is earlier than the starting time of the collision of the aperiodic SRS transmission.

[0146] In some embodiments, the PUCCH transmission in the above examples can only carry a CSI report, only carry an L1-RSRP report, or only carry an L1-SINR report. Among them, the CSI report, the L1-RSRP report, and the L1-SINR report can be periodic, semi-persistent, or periodic.

[0147] Need to be explained, the above is only an example of N uplink transmissions in a time slot, there can be other cases of uplink transmission conflict, the embodiments of the present disclosure do not make specific limitations.

[0148] Four, the conflict processing of SRS is introduced:

[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, which is easy to conflict with other uplink channels / signals, therefore, the sending priority of uplink transmission when conflict is defined in the protocol.

[0150] In some embodiments, the conflict processing rules of 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 non-periodic, semi-persistent or periodic SRS.

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

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

[0154] 4. In the case of not sending SRS due to overlapping with PUCCH, the terminal only drops the SRS configured symbol overlapping with the PUCCH configured symbol.

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

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

[0157] 1. In the case that aperiodic SRS resource is triggered on the OFDM symbol where periodic or semi-persistent SRS is configured, the terminal can transmit the aperiodic SRS resource and only drop the symbol where periodic or semi-persistent SRS is configured, while still transmitting the symbol where periodic or semi-persistent SRS is configured and does not overlap with the aperiodic SRS resource.

[0158] 2. In the case that semi-persistent SRS resource is triggered on the OFDM symbol where periodic SRS is configured, the terminal can transmit the semi-persistent SRS resource and only drop the symbol where periodic SRS is configured, while still transmitting the symbol where periodic SRS is configured and does not overlap with the semi-persistent SRS resource.

[0159] In some embodiments, in the above conflict handling rules, the priority of different types of SRS from high to low is: aperiodic SRS, semi-persistent SRS, periodic SRS.

[0160] In some embodiments, the terms "SRS", "SRS transmission" can be replaced with each other. In some embodiments, the terms "SRS resource", "SRS time domain resource", "SRS symbol", "SRS configured time domain resource", "SRS configured symbol" can be replaced with each other.

[0161] In some embodiments, the terms "PUCCH", "PUCCH transmission" can be replaced with each other. In some embodiments, the terms "PUCCH resource", "PUCCH time domain resource", "PUCCH symbol", "PUCCH configured time domain resource", "PUCCH configured symbol" can be replaced with each other.

[0162] In some embodiments, for the case that N (N≥3) uplink transmissions in a slot shown in FIG. 1C to FIG. 1E collide, if the collision processing is performed according to the above-mentioned collision processing rules, there will be some collision processing rules that are not defined, so that in these cases, the behavior of the terminal will be uncertain, and thus the actual sending behavior of the terminal will be inconsistent.

[0163] To solve the above technical problems, the embodiments of the present disclosure provide a communication method. In the embodiments of the present disclosure, in the case that 3 or more (i.e., N≥3) uplink transmissions in a slot overlap in time domain resources, a communication device can determine one or more uplink transmissions actually sent in the slot and the symbols actually occupied by the uplink transmission according to the collision processing order of the uplink transmissions, thereby realizing the processing of the collision of the uplink transmissions in the time domain.

[0164] FIG. 2A is a first flowchart of a communication method performed by a communication device according to an embodiment of the present disclosure. The communication method related to the embodiments of the present disclosure can be applied to the communication device in the communication system 100. As shown in FIG. 2A, the communication method of the embodiments of the present disclosure includes steps S2101 to S2103.

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

[0166] In some embodiments, the communication method related to the embodiments of the present disclosure is described taking the case that 3 (i.e., N=3) uplink transmissions in a slot (such as the first slot) collide as an example.

[0167] It should be noted that the uplink transmissions that collide in a slot can also be 4, 5, 6, or even more (i.e., N>3), and the collision processing of these uplink transmissions can be referred to steps S2101 to S2102, which will not be described here in detail.

[0168] In step S2101, the collision processing order of 3 uplink transmissions in a slot is determined.

[0169] In some embodiments, in the case that 3 uplink transmissions in a slot collide, the communication device determines the collision processing order of the 3 uplink transmissions.

[0170] In some embodiments, the three uplink transmissions in a slot are uplink transmissions on a same carrier. In an embodiment, the uplink transmissions can include SRS transmissions and uplink channel (e.g., PUCCH) transmissions. In an embodiment, the SRS transmissions can include aperiodic SRS transmissions, semi-persistent SRS transmissions, and periodic SRS transmissions. In an embodiment, the PUCCH transmissions can include at least one of format 0 PUCCH transmission, format 1 PUCCH transmission, format 2 PUCCH transmission, format 3 PUCCH transmission, and format 4 PUCCH transmission.

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

[0172] In some embodiments, the collision of the three uplink transmissions in a slot can include at least two of a collision between multiple SRS transmissions and a collision between an SRS transmission and a PUCCH transmission. In other words, in a slot, the colliding uplink transmissions can include at least three of multiple SRS transmissions and a PUCCH transmission. In an embodiment, in a slot, the collision occurs between multiple SRS transmissions, or the collision occurs between multiple SRS transmissions and at least one SRS transmission and a PUCCH transmission. In an embodiment, each colliding pair of uplink transmissions can be two SRS transmissions or an SRS transmission and a PUCCH transmission.

[0173] In an embodiment, in a slot, the overlap between the time-domain resources configured for the two uplink transmissions can include an overlap between the time-domain resources configured for two SRS transmissions and an overlap between the time-domain resources configured for an SRS transmission and the time-domain resources configured for a PUCCH transmission.

[0174] In some embodiments, a communication device can determine the collision handling order of the three uplink transmissions in a slot according to predefined information (e.g., a protocol specification). In an embodiment, the communication device determines the collision handling order of each colliding pair of uplink transmissions in the three uplink transmissions in a slot according to the predefined information. Based on this, the communication device determines the collision handling order of the three uplink transmissions in a slot according to the predefined information, which reduces signaling interaction and saves system signaling overhead.

[0175] In an embodiment, the conflict processing order of the three uplink transmissions can be determined according to the order of the starting time points at which the time domain resources configured for the three uplink transmissions overlap. In an embodiment, the conflict processing order of the three uplink transmissions can be determined according to the order of the starting time points at which the three uplink transmissions conflict. In an embodiment, the conflict processing order of the three uplink transmissions can be the order of the starting time points at which the time domain resources configured for the three uplink transmissions overlap.

[0176] In an example, referring to FIG. 1C, the aperiodic SRS transmission and the PUCCH transmission conflict at time t1, and the starting time point at which the time domain resources configured for the aperiodic SRS transmission overlap with the time domain resources configured for the PUCCH transmission is time t1.

[0177] The PUCCH transmission and the periodic SRS transmission conflict at time t2, and the starting time point at which the time domain resources configured for the PUCCH transmission overlap with the time domain resources configured for the periodic SRS transmission is time t2. Since time t1 < time t2, the communication device can determine the conflict processing order of the aperiodic SRS transmission, the PUCCH transmission and the periodic SRS transmission in the order of the starting time points at which the overlap occurs as the conflict of the aperiodic SRS transmission and the PUCCH transmission, the conflict of the PUCCH transmission and the periodic SRS transmission.

[0178] In some embodiments, after the communication device determines the conflict processing order in the order of the starting time points at which the time domain resources configured for the three uplink transmissions overlap, there are at least two uplink transmissions corresponding to the same starting time point at which the overlap occurs. In this case, the communication device can further determine the conflict processing order of the at least two uplink transmissions in the order of the priority of the uplink transmissions from low to high or in the order of the priority of the uplink transmissions from high to low.

[0179] In an example, FIG. 1D is another schematic diagram of uplink transmission conflicts, according to an embodiment of the present disclosure. As shown in FIG. 1D, the aperiodic SRS transmission collides with the PUCCH transmission at time t1, and the starting time of the overlap between the time-domain resource transmission configured for the aperiodic SRS transmission and the time-domain resource configured for the PUCCH transmission is time t1. The aperiodic SRS transmission collides with the periodic SRS transmission at time t2, and the starting time of the overlap between the time-domain resource transmission configured for the aperiodic SRS transmission and the time-domain resource configured for the periodic SRS transmission is time t2. The PUCCH transmission also collides with the periodic SRS transmission at time t2, and the starting time of the overlap between the time-domain resource transmission configured for the PUCCH transmission and the time-domain resource configured for the periodic SRS transmission is still time t2. First, since time t1 < time t2, the communication device can determine to process the collision between the aperiodic 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 the processing order of the collision between the aperiodic SRS transmission and the periodic SRS transmission and the collision between the PUCCH transmission and the periodic SRS transmission according to the order from low to high or from high to low of the priority of the aperiodic SRS transmission, the PUCCH transmission, and the periodic SRS transmission. If according to the order from low to high of the priority, the communication device can determine to process the collision between the PUCCH transmission and the periodic SRS transmission first, and then process the collision between the aperiodic SRS transmission and the periodic SRS transmission. At this time, the processing order of the collision between the aperiodic SRS transmission, the PUCCH transmission, and the periodic SRS transmission is: the collision between the aperiodic SRS transmission and the PUCCH transmission, the collision between the PUCCH transmission and the periodic SRS transmission, and the collision between the aperiodic SRS transmission and the periodic SRS transmission. If according to the order from high to low of the priority, the communication device can determine to process the collision between the aperiodic SRS transmission and the periodic SRS transmission first, and then process the collision between the PUCCH transmission and the periodic SRS transmission. At this time, the processing order of the collision between the aperiodic SRS transmission, the PUCCH transmission, and the periodic SRS transmission is: the collision between the aperiodic SRS transmission and the PUCCH transmission, the collision between the aperiodic SRS transmission and the periodic SRS transmission, and the collision between the PUCCH transmission and the periodic SRS transmission.

[0180] In an example, FIG. 1E is another schematic diagram of uplink transmission collision, according to an embodiment of the present disclosure. As shown in FIG. 1E, the periodic SRS transmission collides with the PUCCH transmission at time t1, and the starting time of the overlapping of the time-domain resource transmission configured for the periodic SRS transmission and the time-domain resource configured for the PUCCH transmission is time t1. The aperiodic SRS transmission collides with the periodic SRS transmission at time t2, and the starting time of the overlapping of the time-domain resource transmission configured for the aperiodic SRS transmission and the time-domain resource configured for the periodic SRS transmission is time t2. The PUCCH transmission also collides with the aperiodic SRS transmission at time t2, and the starting time of the overlapping of the time-domain resource transmission configured for the PUCCH transmission and the time-domain resource configured for the aperiodic SRS transmission is still time t2. First, since time t1 < time t2, the communication device can determine to process the collision of the periodic SRS transmission and the PUCCH transmission first according to the order of the starting time of the overlapping. Then, the communication device can further determine the processing order of the collision of the aperiodic SRS transmission and the periodic SRS transmission and the collision of the PUCCH transmission and the aperiodic SRS transmission according to the order of the priority of the aperiodic SRS transmission, the PUCCH transmission and the periodic SRS transmission from low to high or from high to low. If according to the order of the priority from low to high, the communication device can determine to process the collision of the aperiodic SRS transmission and the periodic SRS transmission first and then process the collision of the PUCCH transmission and the aperiodic SRS transmission. At this time, the processing order of the collision of the aperiodic SRS transmission, the PUCCH transmission and the periodic SRS transmission is: the collision of the periodic SRS transmission and the PUCCH transmission, the collision of the aperiodic SRS transmission and the periodic SRS transmission, and the collision of the PUCCH transmission and the aperiodic SRS transmission. If according to the order of the priority from high to low, the communication device can determine to process the collision of the aperiodic SRS transmission and the PUCCH first and then process the collision of the aperiodic SRS transmission and the periodic SRS transmission. At this time, the processing order of the collision of the aperiodic SRS transmission, the PUCCH transmission and the periodic SRS transmission is: the collision of the periodic SRS transmission and the PUCCH transmission, the collision of the aperiodic SRS transmission and the PUCCH transmission, and the collision of the aperiodic SRS transmission and the periodic SRS transmission.

[0181] In an embodiment, the processing order of the collision of the three uplink transmissions can be determined according to the order of the priority of the uplink transmissions from low to high. In an embodiment, the processing order of the collision of the three uplink transmissions can be the order of the priority of the three uplink transmissions from low to high.

[0182] In an example, referring to FIG. 1C, the priority of the aperiodic SRS transmission, the PUCCH transmission and the periodic SRS transmission is in the order from low to high as: the periodic SRS transmission, the PUCCH transmission, the aperiodic SRS transmission. Thus, the communication device can determine the conflict handling order of the aperiodic SRS transmission, the PUCCH transmission and the periodic SRS transmission in the order from low to high priority as: the conflict of the periodic SRS transmission and the PUCCH transmission, the conflict of the PUCCH transmission and the aperiodic SRS transmission.

[0183] In an example, referring to FIG. 1D, the priority of the aperiodic SRS transmission, the PUCCH transmission and the periodic SRS transmission is in the order from low to high as: the periodic SRS transmission, the PUCCH transmission, the aperiodic SRS transmission. Thus, the communication device can determine the conflict handling order of the aperiodic SRS transmission, the PUCCH transmission and the periodic SRS transmission in the order from low to high priority as: the conflict of the periodic SRS transmission and the PUCCH transmission, the conflict of the periodic SRS transmission and the aperiodic SRS transmission, the conflict of the PUCCH transmission and the aperiodic SRS transmission.

[0184] In an example, referring to FIG. 1E, the priority of the aperiodic SRS transmission, the PUCCH transmission and the periodic SRS transmission is in the order from low to high as: the periodic SRS transmission, the PUCCH transmission, the aperiodic SRS transmission. Thus, the communication device can determine the conflict handling order of the aperiodic SRS transmission, the PUCCH transmission and the periodic SRS transmission in the order from low to high priority as: the conflict of the periodic SRS transmission and the PUCCH transmission, the conflict of the periodic SRS transmission and the aperiodic SRS transmission, the conflict of the PUCCH transmission and the aperiodic SRS transmission.

[0185] In an embodiment, the conflict handling order of the three uplink transmissions can be determined in the order from high to low priority of the uplink transmissions. In an embodiment, the conflict handling order of the three uplink transmissions can be the order from high to low priority of the three uplink transmissions.

[0186] In an example, referring to FIG. 1C, the priority of the aperiodic SRS transmission, the PUCCH transmission and the periodic SRS transmission is in the order from high to low as: the aperiodic SRS transmission, the PUCCH transmission, the periodic SRS transmission. Thus, the communication device can determine the conflict handling order of the aperiodic SRS transmission, the PUCCH transmission and the periodic SRS transmission in the order from high to low priority as: the conflict of the aperiodic SRS transmission and the PUCCH transmission, the conflict of the PUCCH transmission and the periodic SRS transmission.

[0187] In an example, referring to FIG. 1D, the priorities of the aperiodic SRS transmission, the PUCCH transmission and the periodic SRS transmission are, from high to low, the aperiodic SRS transmission, the PUCCH transmission and the periodic SRS transmission. Therefore, the communication device can determine, according to the order of the priorities from high to low, the conflict processing order of the aperiodic SRS transmission, the PUCCH transmission and the periodic SRS transmission to be, in sequence, the conflict between the aperiodic SRS transmission and the PUCCH transmission, the conflict between the aperiodic SRS transmission and the periodic SRS transmission, and the conflict between the PUCCH transmission and the periodic SRS transmission.

[0188] In an example, referring to FIG. 1D, the priorities of the aperiodic SRS transmission, the PUCCH transmission and the periodic SRS transmission are, from high to low, the aperiodic SRS transmission, the PUCCH transmission and the periodic SRS transmission. Therefore, the communication device can determine, according to the order of the priorities from high to low, the conflict processing order of the aperiodic SRS transmission, the PUCCH transmission and the periodic SRS transmission to be, in sequence, the conflict between the aperiodic SRS transmission and the PUCCH transmission, the conflict between the aperiodic SRS transmission and the periodic SRS transmission, and the conflict between the PUCCH transmission and the periodic SRS transmission.

[0189] It should be noted that, in the conflict processing of the N (N≥3) uplink transmissions, a certain conflict can disappear with the processing of other conflicts, at which time the communication device can sequentially process the next conflict. For example, according to the above conflict processing order, after processing the ith conflict, the i+1th conflict can not exist, at which time the communication device can sequentially process the i+2th conflict, i≤N-2, i being a positive integer.

[0190] In step S2102, according to the conflict processing order, the actual transmitted uplink transmission in the time-domain resources configured for the two uplink transmissions that overlap and the symbols occupied by the uplink transmission are sequentially determined.

[0191] In some embodiments, the communication device can, for a time slot (i.e., the first time slot) in which a conflict occurs, sequentially process the conflict between the two uplink transmissions that overlap in the three uplink transmissions according to the conflict processing order, thereby determining the actual transmitted uplink transmission in the time-domain resources configured for the two uplink transmissions and the symbols occupied by the uplink transmission.

[0192] In some embodiments, the order of the collision handling of the three uplink transmissions is determined according to the order of the starting time of the overlapping time domain resources configured for the three uplink transmissions, in which case the communication device can handle the collision between two uplink transmissions in the order of the starting time of the overlapping time domain resources configured for the two uplink transmissions to determine the uplink transmission actually transmitted in the time domain resources configured for the two uplink transmissions and the symbols occupied by the uplink transmission. In an embodiment, if the two uplink transmissions in collision are SRS transmissions of different types, the communication device handles the collision between the two uplink transmissions according to the priority of the SRS transmissions of different types. In an embodiment, if the two uplink transmissions in collision are an SRS transmission and a PUCCH transmission, the communication device handles the collision between the two uplink transmissions according to the priority of the SRS transmission and the PUCCH transmission.

[0193] In some embodiments, when the communication device handles the collision between two uplink transmissions according to the priority of the SRS transmissions of different types, the communication device can handle the collision between the two SRS transmissions according to the collision handling rule of the SRS transmissions of different types. In an embodiment, when the communication device handles the collision between the two SRS transmissions according to the collision handling rule of the SRS transmissions of different types, the communication device can determine to transmit the SRS transmission of high priority in the overlapping symbol (e.g., the first symbol) in the time domain resources configured for the SRS transmission of low priority, and transmit the SRS transmission of low priority in the other symbols (e.g., the second symbol) in a slot. In an embodiment, when the communication device handles the collision between the two SRS transmissions according to the collision handling rule of the SRS transmissions of different types, the communication device can determine to discard the overlapping symbol (e.g., the first symbol) in the time domain resources configured for the SRS transmission of low priority.

[0194] In an example, the communication device can determine to transmit the aperiodic or semi-persistent SRS transmission in the overlapping symbol in the time domain resources configured for the periodic SRS transmission, and transmit the periodic SRS transmission in the other symbols in a slot.

[0195] In an example, the communication device can determine to transmit the aperiodic SRS transmission in the overlapping symbol in the time domain resources configured for the semi-persistent SRS transmission, and transmit the semi-persistent SRS transmission in the other symbols in a slot.

[0196] In an example, the communication device can determine to discard the overlapping symbol in the time domain resources configured for the periodic SRS transmission.

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

[0198] In an example, in case of a SRS resource with parameter "resourceType" set to "aperiodic" triggered on an OFDM symbol where periodic or semi-persistent SRS is configured, the communication device can transmit the aperiodic SRS resource and only drop the symbol where periodic or semi-persistent SRS is configured within the symbol, while still determine to transmit the symbol where periodic or semi-persistent SRS is configured not overlapping with the aperiodic SRS resource.

[0199] In an example, in case of a SRS resource with parameter "resourceType" set to "semi-persistent" triggered on an OFDM symbol where periodic SRS is configured, the communication device can transmit the semi-persistent SRS resource and only drop the symbol where periodic SRS is configured within the symbol, while still determine to transmit the symbol where periodic SRS is configured not overlapping with the semi-persistent SRS resource.

[0200] In some embodiments, the communication device can handle the collision between the SRS transmission and the PUCCH transmission according to the collision handling rule of the SRS transmission and the PUCCH transmission when handling the collision between the two uplink transmissions according to the priority of the SRS transmission and the PUCCH transmission. In an embodiment, the communication device can determine to transmit the high priority uplink transmission on the overlapping symbol (e.g., the first symbol) in the time domain resource where the high priority uplink transmission is configured and transmit the low priority uplink transmission on the other symbol (e.g., the second symbol) in a slot when handling the collision between the SRS transmission and the PUCCH transmission according to the collision handling rule of the SRS transmission and the PUCCH transmission. In an embodiment, the communication device can determine to drop the overlapping symbol (e.g., the first symbol) in the time domain resource where the low priority uplink transmission is configured when handling the collision between the SRS transmission and the PUCCH transmission according to the collision handling rule of the SRS transmission and the PUCCH transmission. In an embodiment, the length of the time domain resource where the PUCCH transmission is configured is larger than the length of the time domain resource where the SRS transmission is configured, and the time domain resource where the SRS transmission is configured overlaps with the time domain resource where the PUCCH transmission is configured as a whole. If the priority of the SRS transmission is lower than the priority of the PUCCH transmission, the communication device can determine to drop the time domain resource where the SRS transmission is configured. If the priority of the SRS transmission is higher than the priority of the PUCCH transmission, the communication device determines to drop the time domain resource where the PUCCH transmission is configured in a slot.

[0201] In an example, the communication device can determine to transmit the PUCCH transmission on an overlapping symbol (e.g., a first symbol) in a time domain resource where the PUCCH transmission is configured, and to transmit the aperiodic SRS transmission on other symbols (e.g., a second symbol) in a slot. At this time, the PUCCH transmission carries only a CSI report, only an L1-RSRP report, or only an L1-SINR report; the CSI report, the L1-RSRP report, and the L1-SINR report can be periodic, aperiodic, or semi-persistent.

[0202] In an example, the communication device can determine to transmit the aperiodic SRS transmission on an overlapping symbol (e.g., a first symbol) in a time domain resource where the aperiodic SRS transmission is configured, and to transmit the PUCCH transmission on other symbols (e.g., a second symbol) in a slot. At this time, the PUCCH transmission carries only a CSI report, only an L1-RSRP report, or only an L1-SINR report; the CSI report, the L1-RSRP report, and the L1-SINR report can be periodic, aperiodic, or semi-persistent.

[0203] In an example, in a case where a time domain resource where the SRS transmission is configured overlaps with a time domain resource where the uplink channel transmission is configured, it is determined not to transmit the SRS transmission on the overlapping symbol, wherein the SRS transmission comprises a semi-persistent SRS transmission or a periodic SRS transmission; the uplink channel transmission carries only the first information; the first information comprises at least one of: a CSI report, an L1-RSRP report, and an L1-SINR report; and the first information is transmitted periodically, aperiodically, or semi-persistently.

[0204] In an example, in a case where a time domain resource where the aperiodic SRS transmission is configured overlaps with a time domain resource where the uplink channel transmission is configured, it is determined not to transmit the PUCCH transmission, wherein the uplink channel transmission carries the first information; the first information comprises at least one of: a CSI report, an L1-RSRP report, and an L1-SINR report; and the first information is transmitted periodically, aperiodically, or semi-persistently.

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

[0206] In some embodiments, the PUCCH transmission can further carry at least one of a HARQ-ACK, a link recovery request, and an SR, and in this case, the communication device can determine to transmit the PUCCH transmission on an overlapping symbol (e.g., a first symbol) in a time domain resource where the PUCCH transmission is configured, and to transmit the aperiodic, semi-persistent, or periodic SRS transmission on other symbols (e.g., a second symbol) in a slot.

[0207] In an example, in a case that the time domain resource configured for the SRS transmission overlaps with the time domain resource configured for the second uplink transmission, it is determined that the SRS transmission is not transmitted on the overlapped symbol, wherein the SRS transmission comprises a semi-persistent SRS transmission, a periodic SRS transmission, and an aperiodic SRS transmission, and the second uplink transmission carries second information, and the second information comprises at least one of the following: a HARQ-ACK, a link recovery request, and a SR.

[0208] In an embodiment, in the case that the SRS transmission is determined not to be transmitted due to the overlap, the communication device can determine to drop the overlapped symbol in the time domain resource configured for the SRS transmission. In an embodiment, in the case that the SRS transmission is determined not to be transmitted on the overlapped symbol, the communication device can determine to drop the overlapped symbol in the time domain resource configured for the SRS transmission.

[0209] In an example, for the conflict shown in FIG. 1C, FIG. 3A is a first schematic diagram of 3 uplink transmission conflict processing according to an embodiment of the present disclosure, wherein the dashed line represents the time domain resource of the dropped uplink transmission. As shown in FIG. 3A, the conflict processing order of the aperiodic SRS transmission, the PUCCH transmission, and the periodic SRS transmission is the conflict between the aperiodic SRS transmission and the PUCCH transmission, the conflict between the PUCCH transmission and the periodic SRS transmission. At this time, the communication device processes the conflict between the aperiodic SRS transmission and the PUCCH transmission first, and according to the conflict processing rule of the SRS transmission and the PUCCH transmission, the communication device determines to transmit the aperiodic SRS transmission on the time domain resource configured for the aperiodic SRS transmission, and drops the time domain resource configured for the PUCCH transmission in a time slot. Then, the communication device processes the conflict between the PUCCH transmission and the periodic SRS transmission, and since the time domain resource configured for the PUCCH transmission in a time slot is dropped, the conflict between the PUCCH transmission and the periodic SRS transmission does not exist, and then the communication device determines to transmit the periodic SRS transmission on the time domain resource configured for the periodic SRS transmission.

[0210] In an example, for the conflict shown in FIG. 1D, FIG. 3B is a second schematic diagram illustrating 3 uplink transmission conflict processing according to an embodiment of the present disclosure, wherein the dashed line represents the time domain resource and overlapping symbol of the discarded uplink transmission. As shown in FIG. 3B, the conflict processing order of the aperiodic SRS transmission, the PUCCH transmission and the periodic SRS transmission is the conflict between the aperiodic SRS transmission and the PUCCH transmission, the conflict between the PUCCH transmission and the periodic SRS transmission, and the conflict between the aperiodic SRS transmission and the periodic SRS transmission. At this time, the communication device first processes the conflict between the aperiodic SRS transmission and the PUCCH transmission. According to the conflict processing rule of the SRS transmission and the PUCCH transmission, the communication device determines to send the aperiodic SRS transmission on the time domain resource configured for the aperiodic SRS transmission, and discards the time domain resource configured for the PUCCH transmission in a slot. Then, the communication device processes the conflict between the PUCCH transmission and the periodic SRS transmission. Since the time domain resource configured for the PUCCH transmission in a slot is discarded, the conflict between the PUCCH transmission and the periodic SRS transmission does not exist. At this time, the communication device continues to process the conflict between the aperiodic SRS transmission and the periodic SRS transmission. Then, the communication device determines to send the aperiodic SRS transmission on the time domain resource configured for the aperiodic SRS transmission, and to send the periodic SRS transmission on the symbol (e.g., the second symbol) except the overlapping symbol (e.g., the first symbol) in the time domain resource configured for the periodic SRS transmission, according to the conflict processing rule of different types of SRS transmissions.

[0211] In an example, for the conflict shown in FIG. 1D, referring to FIG. 3B, the conflict processing order of the aperiodic SRS transmission, the PUCCH transmission and the periodic SRS transmission is the conflict of the aperiodic SRS transmission and the PUCCH transmission, the conflict of the aperiodic SRS transmission and the periodic SRS transmission, and the conflict of the PUCCH transmission and the periodic SRS transmission. At this time, the communication device first processes the conflict of the aperiodic SRS transmission and the PUCCH transmission. According to the conflict processing rule of the SRS transmission and the PUCCH transmission, the communication device determines to send the aperiodic SRS transmission on the time domain resource configured for the aperiodic SRS transmission, and discards the time domain resource configured for the PUCCH transmission in one time slot. Then, the communication device processes the conflict of the aperiodic SRS transmission and the periodic SRS transmission. At this time, the communication device determines to send the aperiodic SRS transmission on the time domain resource configured for the aperiodic SRS transmission, and to send the periodic SRS transmission on the symbol (for example, the second symbol) except the overlapping symbol (for example, the first symbol) in the time domain resource configured for the periodic SRS transmission, according to the conflict processing rule of different types of SRS transmissions. Next, the communication device processes the conflict of the PUCCH transmission and the periodic SRS transmission. Since the time domain resource configured for the PUCCH transmission in one time slot is discarded, the conflict of the PUCCH transmission and the periodic SRS transmission does not exist, and thus the communication device does not process it.

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

[0213] In an example, for the collision shown in FIG. 1E, referring to FIG. 3C, the collision processing order of the aperiodic SRS transmission, the PUCCH transmission and the periodic SRS transmission is the collision between the periodic SRS transmission and the PUCCH transmission, the collision between the aperiodic SRS transmission and the PUCCH transmission, and the collision between the aperiodic SRS transmission and the periodic SRS transmission. At this time, the communication device processes the collision between the periodic SRS transmission and the PUCCH transmission first. According to the collision processing rule of the SRS transmission and the PUCCH transmission, the communication device determines to transmit the PUCCH transmission on the time domain resource configured for the PUCCH transmission, and discards the time domain resource configured for the periodic SRS transmission. Then, the communication device processes the collision between the aperiodic SRS transmission and the PUCCH transmission. At this time, according to the collision processing rule of the SRS transmission and the PUCCH transmission, the communication device determines to transmit the aperiodic SRS transmission on the time domain resource configured for the aperiodic SRS transmission, and discards the time domain resource configured for the PUCCH transmission in one slot. Next, the communication device processes the collision between the aperiodic SRS transmission and the periodic SRS transmission. Since the time domain resource configured for the periodic SRS transmission is discarded, the collision between the aperiodic SRS transmission and the periodic SRS transmission does not exist, and thus the communication device does not process it.

[0214] In some embodiments, the collision processing order of the three uplink transmissions is determined according to the priority of the three uplink transmissions from low to high. In this case, the communication device can process the collision between two uplink transmissions in turn according to the priority of the three uplink transmissions from low to high, to determine the uplink transmission actually transmitted in the time domain resource configured for the two uplink transmissions and the symbol occupied by the uplink transmission. In an embodiment, if the two uplink transmissions in collision are different types of SRS transmissions, the communication device processes the collision between the two uplink transmissions according to the priority of the different types of SRS transmissions. In an embodiment, if the two uplink transmissions in collision are an SRS transmission and a PUCCH transmission, the communication device processes the collision between the two uplink transmissions according to the priority of the different types of SRS transmission and PUCCH transmission.

[0215] In an example, for the conflict shown in FIG. 1C, FIG. 4A is a fourth schematic diagram of 3 uplink transmission conflict processing, according to an embodiment of the present disclosure, wherein the dashed line represents the time domain resource of the discarded uplink transmission. As shown in FIG. 4A, the conflict processing order of the periodic SRS transmission, the PUCCH transmission and the aperiodic SRS transmission is the conflict between the periodic SRS transmission and the PUCCH transmission, the conflict between the PUCCH transmission and the aperiodic SRS transmission. At this time, the communication device first processes the conflict between the periodic SRS transmission and the PUCCH transmission, and according to the conflict processing rule of the SRS transmission and the PUCCH transmission, the communication device determines to send the PUCCH transmission on the time domain resource configured for the PUCCH transmission, and discards the time domain resource configured for the periodic SRS transmission. Then, the communication device processes the conflict between the PUCCH transmission and the aperiodic SRS transmission, and according to the conflict processing rule of the SRS transmission and the PUCCH transmission, the communication device determines to send the aperiodic SRS transmission on the time domain resource configured for the aperiodic SRS transmission, and discards the time domain resource configured for the PUCCH transmission in a time slot.

[0216] In an example, for the conflict shown in FIG. 1D, FIG. 4B is a fifth schematic diagram of 3 uplink transmission conflict processing, according to an embodiment of the present disclosure. As shown in FIG. 4B, the conflict processing order of the periodic SRS transmission, the PUCCH transmission and the aperiodic SRS transmission is the conflict between the periodic SRS transmission and the PUCCH transmission, the conflict between the periodic SRS transmission and the aperiodic SRS transmission, and the conflict between the PUCCH transmission and the aperiodic SRS transmission. At this time, the communication device first processes the conflict between the periodic SRS transmission and the PUCCH transmission, and according to the conflict processing rule of the SRS transmission and the PUCCH transmission, the communication device determines to send the PUCCH transmission on the time domain resource configured for the PUCCH transmission, and discards the time domain resource configured for the periodic SRS transmission. Then, the communication device processes the conflict between the periodic SRS transmission and the aperiodic SRS transmission, and since the time domain resource configured for the periodic SRS transmission is discarded, the conflict between the periodic SRS transmission and the aperiodic SRS transmission does not exist, at this time, the communication device continues to process the conflict between the PUCCH transmission and the aperiodic SRS transmission. Then, according to the conflict processing rule of the SRS transmission and the PUCCH transmission, the communication device determines to send the aperiodic SRS transmission on the time domain resource configured for the aperiodic SRS transmission, and discards the time domain resource configured for the PUCCH transmission in a time slot.

[0217] In an example, for the conflict shown in FIG. 1E, FIG. 4C is a sixth schematic diagram of 3 uplink transmission conflict processing, according to an embodiment of the present disclosure. As shown in FIG. 4C, the conflict processing order of the periodic SRS transmission, the PUCCH transmission and the aperiodic SRS transmission is: the conflict of the periodic SRS transmission and the PUCCH transmission, the conflict of the periodic SRS transmission and the aperiodic SRS transmission, and the conflict of the PUCCH transmission and the aperiodic SRS transmission. At this time, the communication device first processes the conflict of the periodic SRS transmission and the PUCCH transmission. According to the conflict processing rule of the SRS transmission and the PUCCH transmission, the communication device determines to send the PUCCH transmission on the time domain resource configured for the PUCCH transmission, and discards the time domain resource configured for the periodic SRS transmission. Then, the communication device processes the conflict of the periodic SRS transmission and the aperiodic SRS transmission. Since the time domain resource configured for the periodic SRS transmission is discarded, the conflict of the periodic SRS transmission and the aperiodic SRS transmission does not exist. At this time, the communication device continues to process the conflict of the PUCCH transmission and the aperiodic SRS transmission. Then, according to the conflict processing rule of the SRS transmission and the PUCCH transmission, the communication device determines to send the aperiodic SRS transmission on the time domain resource configured for the aperiodic SRS transmission, and discards the time domain resource configured for the PUCCH transmission in a time slot.

[0218] In some embodiments, the conflict processing order of the 3 uplink transmissions is determined according to the priority of the 3 uplink transmissions from high to low. In this case, the communication device can process the conflict between two uplink transmissions in turn according to the priority of the 3 uplink transmissions from high to low, to determine the uplink transmission actually sent in the time domain resource configured for the two uplink transmissions and the symbol occupied by the uplink transmission. In an embodiment, if the two uplink transmissions in conflict are different types of SRS transmissions, the communication device processes the conflict between the two uplink transmissions according to the priority of the different types of SRS transmissions. In an embodiment, if the two uplink transmissions in conflict are SRS transmission and PUCCH transmission, the communication device processes the conflict between the two uplink transmissions according to the priority of the different types of SRS transmission and PUCCH transmission.

[0219] In an example, for the conflict shown in FIG. 1C, referring to FIG. 3A, the conflict processing order of the aperiodic SRS transmission, the PUCCH transmission and the periodic SRS transmission is the conflict of the aperiodic SRS transmission and the PUCCH transmission, the conflict of the PUCCH transmission and the periodic SRS transmission. At this time, the communication device processes the conflict of the aperiodic SRS transmission and the PUCCH transmission first. According to the conflict processing rule of the SRS transmission and the PUCCH transmission, the communication device determines to send the aperiodic SRS transmission on the time domain resource configured for the aperiodic SRS transmission, and discards the time domain resource configured for the PUCCH transmission in one slot. Then, the communication device processes the conflict of the PUCCH transmission and the periodic SRS transmission. Since the time domain resource configured for the PUCCH transmission is discarded, the conflict of the PUCCH transmission and the periodic SRS transmission does not exist. Therefore, the communication device determines to send the periodic SRS transmission on the time domain resource configured for the periodic SRS transmission.

[0220] In an example, for the conflict shown in FIG. 1D, still referring to FIG. 3B, the conflict processing order of the aperiodic SRS transmission, the PUCCH transmission and the periodic SRS transmission is the conflict of the aperiodic SRS transmission and the PUCCH transmission, the conflict of the aperiodic SRS transmission and the periodic SRS transmission, the conflict of the PUCCH transmission and the periodic SRS transmission. At this time, the communication device processes the conflict of the aperiodic SRS transmission and the PUCCH transmission first. According to the conflict processing rule of the SRS transmission and the PUCCH transmission, the communication device determines to send the aperiodic SRS transmission on the time domain resource configured for the aperiodic SRS transmission, and discards the time domain resource configured for the PUCCH transmission in one slot. Then, the communication device processes the conflict of the aperiodic SRS transmission and the periodic SRS transmission. At this time, the communication device determines to send the aperiodic SRS transmission on the time domain resource configured for the aperiodic SRS transmission, and to send the periodic SRS transmission on the symbol (such as the second symbol) except the overlapping symbol (such as the first symbol) in the time domain resource configured for the periodic SRS transmission, according to the conflict processing rule of different types of SRS transmissions. Next, the communication device processes the conflict of the PUCCH transmission and the aperiodic SRS transmission. Since the time domain resource configured for the PUCCH transmission in one slot is discarded, the conflict of the PUCCH transmission and the periodic SRS transmission does not exist. Therefore, the communication device does not process.

[0221] In an example, for the conflict shown in FIG. 1E, FIG. 5A is a seventh schematic diagram of 3 uplink transmission conflict processing, according to an embodiment of the present disclosure. As shown in FIG. 5A, the conflict processing order of the aperiodic SRS transmission, the PUCCH transmission and the periodic SRS transmission is the conflict of the aperiodic SRS transmission and the PUCCH transmission, the conflict of the aperiodic SRS transmission and the periodic SRS transmission, and the conflict of the PUCCH transmission and the periodic SRS transmission. At this time, the communication device first processes the conflict of the aperiodic SRS transmission and the PUCCH transmission. According to the conflict processing rule of the SRS transmission and the PUCCH transmission, the communication device determines to send the aperiodic SRS transmission on the time domain resource configured for the aperiodic SRS transmission, and discards the time domain resource configured for the PUCCH transmission in one time slot. Then, the communication device processes the conflict of the aperiodic SRS transmission and the periodic SRS transmission. At this time, the communication device determines to send the aperiodic SRS transmission on the time domain resource configured for the aperiodic SRS transmission, and to send the periodic SRS transmission on the symbol (such as the second symbol) except the overlapping symbol (such as the first symbol) in the time domain resource configured for the periodic SRS transmission, according to the conflict processing rule of different types of SRS transmission. Next, the communication device processes the conflict of the PUCCH transmission and the aperiodic SRS transmission. Since the time domain resource configured for the PUCCH transmission in one time slot is discarded, the conflict of the PUCCH transmission and the periodic SRS transmission does not exist, and thus the communication device does not process it.

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

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

[0224] In some embodiments, after the communication device sequentially determines the actually sent uplink transmission and the symbol occupied by the uplink transmission in the time domain resource configured for the two uplink transmissions where the conflict occurs, the communication device can determine the first uplink transmission sent in one time slot where the conflict occurs and the symbol occupied by the first uplink transmission according to the comprehensive determination result.

[0225] In an example, referring to FIG. 3A, the communication device determines to transmit the aperiodic SRS transmission on the time domain resource on which the aperiodic SRS transmission is configured, and determines to transmit the periodic SRS transmission on the time domain resource on which the periodic SRS transmission is configured, in which case the first uplink transmission includes the aperiodic SRS transmission and the periodic SRS transmission, and the symbol occupied by the first uplink transmission includes the time domain resource on which the aperiodic SRS transmission is configured and the time domain resource on which the periodic SRS transmission is configured.

[0226] In an example, referring to FIG. 3B and FIG. 5A, the communication device determines to transmit the aperiodic SRS transmission on the time domain resource on which the aperiodic SRS transmission is configured, and determines to transmit the periodic SRS transmission on the symbol (e.g., the second symbol) of the time domain resource on which the periodic SRS transmission is configured except the overlapping symbol (e.g., the first symbol), in which case the first uplink transmission includes the aperiodic SRS transmission and the periodic SRS transmission, and the symbol occupied by the first uplink transmission includes the symbol of the time domain resource on which the periodic SRS transmission is configured except the overlapping symbol.

[0227] In an example, referring to FIG. 3C, FIG. 4A, FIG. 4B and FIG. 4C, the communication device determines to transmit the aperiodic SRS transmission on the time domain resource on which the aperiodic SRS transmission is configured, in which case the first uplink transmission includes the aperiodic SRS transmission, and the symbol occupied by the first uplink transmission includes the time domain resource on which the aperiodic SRS transmission is configured.

[0228] In some embodiments, the PUCCH transmission can be configured multiple slots, and the multiple slots include the one slot in which the collision occurs. In an embodiment, if the communication device determines that the first uplink transmission transmitted in the one slot in which the collision occurs does not include the PUCCH transmission, in other words, the communication device determines not to transmit the PUCCH transmission in the one slot in which the collision occurs, the communication device can determine to transmit the PUCCH transmission in the other slots of the multiple slots except the one slot in which the collision occurs. In an embodiment, if the communication device determines that the first uplink transmission transmitted in the one slot in which the collision occurs does not include the PUCCH transmission, in other words, the communication device determines not to transmit the PUCCH transmission in the one slot in which the collision occurs, the communication device can determine not to transmit the PUCCH transmission in the multiple slots.

[0229] In some embodiments, in the case that the communication device is a terminal, after the terminal determines the first uplink transmission transmitted in the one slot in which the collision occurs and the symbol occupied by the first uplink transmission through steps S2101 to S2103, the terminal can transmit the first uplink transmission to the network device on the symbol occupied by the first uplink transmission.

[0230] In some embodiments, in the case that the communication device is a network device, after determining the first uplink transmission sent by the terminal in the time slot in which the collision 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, in the collision shown in FIGS. 1C to 1E, the periodic SRS transmission can be replaced by the semi-persistent SRS transmission. Accordingly, in the examples shown in FIGS. 3A to 3C, 4A to 4C and 5A, the periodic SRS transmission can be replaced by the 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) can also be greater than 3 (i.e., N>3), such as 4 uplink transmissions colliding, 5 uplink transmissions colliding, etc. In an embodiment, in the case of N>3, the communication device can refer to the collision processing procedure of the 3 uplink transmissions in steps S2101 to S2103 above to process the collision of 4 uplink transmissions, 5 uplink transmissions, etc.

[0233] In an example, 4 uplink transmissions colliding is taken as an example for illustration.

[0234] FIG. 1F is a schematic diagram of 4 uplink transmissions colliding according to an embodiment of the present disclosure. As shown in FIG. 1F, the aperiodic SRS transmission, the PUCCH transmission, the periodic SRS transmission and the semi-persistent SRS transmission on the same carrier collide. Among them, the time domain resource configured for the aperiodic SRS transmission overlaps with the time domain resource configured for the PUCCH transmission, the time domain resource configured for the aperiodic SRS transmission overlaps with the time domain resource configured for the periodic SRS transmission, the time domain resource configured for the PUCCH transmission overlaps with the time domain resource configured for the periodic SRS transmission, and the time domain resource configured for the PUCCH transmission overlaps with the time domain resource configured for the semi-persistent SRS transmission. The starting time of the aperiodic 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 aperiodic SRS transmission collides with the PUCCH transmission at time t1, and the starting time of the overlapping of the time-domain resource transmission configured for the aperiodic SRS transmission and the time-domain resource configured for the PUCCH transmission is time t1. The aperiodic SRS transmission collides with the periodic SRS transmission at time t2, and the starting time of the overlapping of the time-domain resource transmission configured for the aperiodic SRS transmission and the time-domain resource configured for the periodic SRS transmission is time t2. The PUCCH transmission also collides with the periodic SRS transmission at time t2, and the starting time of the overlapping of the time-domain resource transmission configured for the PUCCH transmission and the time-domain resource configured for 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 of the overlapping of the time-domain resource transmission configured for the PUCCH transmission and the time-domain resource configured for the semi-persistent SRS transmission is time t4. First, since time t1 < time t2, the communication device can determine to process the collision of the aperiodic SRS transmission and the PUCCH transmission first according to the order of the starting time of the overlapping. Then, the communication device can further determine to process the collision of the PUCCH transmission and the periodic SRS transmission first and the collision of the aperiodic SRS transmission and the periodic SRS transmission second according to the order of the priority of the aperiodic SRS transmission, the PUCCH transmission, and the periodic SRS transmission from low to high. Next, since time t2 < time t4, the communication device can further determine to process the collision of the PUCCH transmission and the semi-persistent SRS transmission according to the order of the starting time of the overlapping. At this time, the order of the collision processing of the aperiodic SRS transmission, the PUCCH transmission, the periodic SRS transmission, and the semi-persistent SRS transmission is: the collision of the aperiodic SRS transmission and the PUCCH transmission, the collision of the PUCCH transmission and the periodic SRS transmission, the collision of the aperiodic SRS transmission and the periodic SRS transmission, and the collision of the PUCCH transmission and the semi-persistent SRS transmission.

[0236] Then, referring to step S2102, FIG. 3D is a first schematic diagram of 4 uplink transmission collision processing according to an embodiment of the present disclosure, wherein the dashed line represents the time domain resource and overlapping symbol of the discarded uplink transmission. As shown in FIG. 3D, the collision processing order of the aperiodic SRS transmission, the PUCCH transmission, the periodic SRS transmission and the semi-persistent SRS transmission is the collision between the aperiodic SRS transmission and the PUCCH transmission, the collision between the PUCCH transmission and the periodic SRS transmission, the collision between the aperiodic SRS transmission and the periodic SRS transmission, and the collision between the PUCCH transmission and the semi-persistent SRS transmission. At this time, the communication device first processes the collision between the aperiodic SRS transmission and the PUCCH transmission. According to the collision processing rule between the SRS transmission and the PUCCH transmission, the communication device determines to send the aperiodic SRS transmission on the time domain resource configured for the aperiodic SRS transmission, and discards the time domain resource configured for the PUCCH transmission in a time slot. Then, the communication device processes the collision between the PUCCH transmission and the periodic SRS transmission. Since the time domain resource configured for the PUCCH transmission in a time slot is discarded, the collision between the PUCCH transmission and the periodic SRS transmission does not exist. At this time, the communication device continues to process the collision between the aperiodic SRS transmission and the periodic SRS transmission. Then, according to the collision processing rule of different types of SRS transmissions, the communication device determines to send the aperiodic SRS transmission on the time domain resource configured for the aperiodic SRS transmission, and to send the periodic SRS transmission on the symbol (such as the second symbol) except the overlapping symbol (such as the first symbol) in the time domain resource configured for the periodic SRS transmission. Next, the communication device continues to process the collision between the PUCCH transmission and the semi-persistent SRS transmission. Since the time domain resource configured for the PUCCH transmission in a time slot is discarded, the collision between the PUCCH transmission and the semi-persistent SRS transmission does not exist. At this time, the communication device determines to send the semi-persistent SRS transmission on the time domain resource configured for the semi-persistent SRS transmission.

[0237] Next, referring to step S2103, referring to FIG. 3D, the communication device determines to send the aperiodic SRS transmission on the time domain resource configured for the aperiodic SRS transmission, to send the periodic SRS transmission on the symbol except the overlapping symbol in the time domain resource configured for the periodic SRS transmission, and to send the semi-persistent SRS transmission on the symbol except the overlapping symbol in the time domain resource configured for the semi-persistent SRS transmission. In this case, the first uplink transmission includes the aperiodic SRS transmission, the periodic SRS transmission and the semi-persistent SRS transmission, and the symbol occupied by the first uplink transmission includes the time domain resource configured for the aperiodic SRS transmission, the symbol except the overlapping symbol in the time domain resource configured for the periodic SRS transmission, and the time domain resource configured for the semi-persistent SRS transmission.

[0238] It should be noted that the above is only an example of 4 uplink transmissions colliding, and other situations of 4 uplink transmissions colliding can also exist, and the embodiments of the present disclosure do not make specific limitations thereon. In some embodiments, for other situations of 4 uplink transmissions colliding, the conflict processing can be performed according to the conflict processing sequence and the conflict processing rule described above.

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

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

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

[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] The optional implementation of step S6101 can also refer to the optional implementation of steps S2101 to S2103 of FIG. 2A and other associated parts in the embodiments involved in FIG. 2A, which will not be repeated here.

[0259] Hereinafter, the technical solutions of the embodiments of the present disclosure are exemplarily described through specific embodiments.

[0260] In some embodiments, according to the conflict discard rule defined in the current protocol, some resource conflict situations are not defined, which may cause uncertainty in UE processing, and ambiguity in understanding the actual sending of the terminal by the network side. For example, for the cases shown in FIGS. 1C-1E, the terminal may need to send aperiodic SRS (AP-SRS) and periodic SRS (P-SRS) or only send AP-SRS according to different rules. It can be seen that the current protocol needs to define the terminal behavior for the above-mentioned cases to avoid inconsistent understanding between the terminal and the network.

[0261] In some embodiments, the present solution is mainly used to define the sending method after the resource conflict between SRS and PUCCH, which is specifically as follows:

[0262] In an embodiment, when the PUCCH (such as the first information) configured by the UE on the same carrier to carry CSI / L1-RSRP / L1-SINR and at least one SRS resource occur resource overlap, the following processing is performed:

[0263] Method 1: According to the priority principle defined in the current protocol, the timeline order of the conflict is applied respectively.

[0264] In an example, for the case shown in FIG. 1C, i.e., t1>t2, first handle the conflict between aperiodic SRS (AP-SRS) and PUCCH, which will discard PUCCH, then there is no need to handle the conflict at t2, and periodic SRS (P-SRS) can still be sent at t2, as shown in FIG. 3A.

[0265] In an example, for the case shown in FIG. 1D, i.e., t1>t2, first handle the conflict between aperiodic SRS (AP-SRS) and PUCCH, which will discard PUCCH, then handle the conflict between aperiodic SRS (AP-SRS) and periodic SRS (P-SRS), which will discard the overlapping symbols of P-SRS, and periodic SRS (P-SRS) can be sent at t3, as shown in FIG. 3B.

[0266] In an example, for the case shown in FIG. 1E, i.e., t1>t2, first handle the conflict between periodic SRS (P-SRS) and PUCCH, which will discard P-SRS, then handle the conflict between aperiodic SRS (AP-SRS) and PUCCH, which will discard PUCCH, as shown in FIG. 3C.

[0267] Method 2: For multiple conflicting resources, first, according to the existing protocol priority rules, start the decision processing from the resource conflict corresponding to the low-priority resource, and then process the resource overlapping conflicts in turn.

[0268] In an example, for the case shown in FIGS. 1C-1E, the priority order is first P-SRS < PUCCH (CSI) < AP-SRS (i.e., the priority of P-SRS is lower than that of PUCCH (including CSI report), and the priority of PUCCH (including CSI report) is lower than that of AP-SRS). In this way, the overlapping problem between P-SRS and PUCCH is first processed, P-SRS is not sent, and then the conflict between AP-SRS and PUCCH is decided, PUCCH is not sent, and therefore, only AP-SRS is actually sent, as shown in FIGS. 4A-4C.

[0269] Method 3: For multiple conflicting resources, first, according to the existing protocol priority rules, start the decision processing from the resource conflict corresponding to the high-priority resource, and then process the resource overlapping conflicts in turn.

[0270] In an example, for the case shown in FIG. 1C, the priority order is first AP-SRS > PUCCH (CSI) > P-SRS (i.e., the priority of AP-SRS is higher than that of PUCCH (including CSI report), and the priority of PUCCH (including CSI report) is higher than that of P-SRS). In this way, the overlapping problem between AP-SRS and PUCCH is first processed, PUCCH is not sent, and P-SRS can be sent because it does not conflict with AP-SRS, and therefore, P-SRS and AP-SRS are actually sent, as shown in FIG. 3A.

[0271] In an example, for the case shown in FIGS. 1D and 1E, the priority order is first AP-SRS > PUCCH (CSI) > P-SRS (i.e., the priority of AP-SRS is higher than that of PUCCH (including CSI report), and the priority of PUCCH (including CSI report) is higher than that of P-SRS). In this way, the overlapping problem between AP-SRS and PUCCH is first processed, PUCCH is not sent, and then the conflict between the aperiodic SRS (AP-SRS) and the periodic SRS (P-SRS) is processed, 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 FIGS. 3B and 5A.
