The terminal device can also be referred to as a terminal or a UE, and those skilled in the art can understand its meaning.

[0049] The access network device 20 is a device deployed in an access network to provide wireless communication functions for the terminal device 10. The access network device 20 can include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems using different wireless access technologies, the names of devices with access network device functions can be different, for example, in a 5G NR system, it is called gNodeB or gNB. As communication technology evolves, the name of the "access network device" may change. For ease of description, in the embodiments of the present application, the above-mentioned devices that provide wireless communication functions for the terminal device 10 are collectively referred to as access network devices. In some embodiments, through the access network device 20, a communication relationship can be established between the terminal device 10 and the core network element 30. Illustratively, in the LTE (Long Term Evolution) system, the access network device 20 can be an EUTRAN (Evolved Universal Terrestrial Radio Access Network) or one or more eNodeBs in the EUTRAN; in the 5G NR system, the access network device 20 can be a RAN (Radio Access Network) or one or more gNBs in the RAN.

These small cells have the characteristics of small coverage and low transmit power, and are suitable for providing high-speed data transmission services.

[0054] Before introducing the technical solutions of the present application, some related technical knowledge involved in the present application will be introduced and explained. The following related technologies can be combined with the technical solutions of the embodiments of the present application in any way, and all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following content.

[0055] 1. SBFD

[0056] In order to overcome the problems of weak uplink coverage, large uplink delay and insufficient uplink capacity caused by the small amount of uplink resource allocation in NR TDD, the 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) introduces the SBFD technology, that is, data can be transmitted and received simultaneously on different subbands of the same subframe / slot / symbol. This technology is mainly used at the base station side, and the terminal side still maintains the current state, that is, only transmission or reception of data is supported within one subframe / slot / symbol. As shown in FIG. 2, the middle subband of one downlink or flexible subframe / slot / symbol is configured as an uplink subband.

[0057] When the UL occupies the full bandwidth, it is dynamic TDD technology. This can be regarded as an extreme case of SBFD, and the transmission direction of time resources can be dynamically adapted based on time slots.

[0058] In addition, the current consensus of 3GPP is that SBFD subband (UL subband and / or DL subband) can only be configured on the DL symbol and / or flexible symbol configured in TDD-UL-DL-ConfigCommon, that is, a more likely frame structure is shown in FIG. 3. In FIG. 3, D represents a downlink symbol, U represents an uplink symbol, and the dotted filled part represents an uplink subband. As can be seen from the figure, the SBFD uplink subband is configured on the downlink symbol.

[0059] 2. Uplink resource muting

[0060] Uplink resource muting is a proposed solution to SBFD CLI. CLI refers to the interference caused by the adjacent base station when the adjacent base station configures different transmission directions or simultaneously receives uplink and transmits downlink in the SBFD time slot. Because the downlink transmission power of the base station is extremely large, the base station receiving uplink data will be interfered by the downlink transmission of the adjacent base station. By measuring the CLI between base stations in some REs without uplink transmission, the interference covariance matrix can be accurately obtained, and the application in the receiver of the enhanced base station can effectively improve the problem of uplink coverage weakening caused by the CLI between base stations.

[0061] FIG. 4 exemplarily shows a schematic diagram of uplink resource muting. In FIG. 4, the 5th symbol (i.e., the white filled square) in the uplink subband is an UL muting symbol, and the 1st symbol (i.e., the cross line filled square) in the uplink subband is an uplink symbol with muting RE.

[0062] FIG. 5 is a schematic diagram of a time-frequency resource configuration that can be implemented for uplink resource muting. In FIG. 4, each square represents an RE, the dotted filled square in the figure represents the RE occupied by PUSCH, the black filled square represents the RE occupied by DMRS (Demodulation Reference Signal), and the white filled square represents the RE occupied by uplink muting resource.

[0063] Please refer to FIG. 6, which shows a flowchart of an uplink transmission method according to an embodiment of the present application. The method can be applied to the network architecture shown in FIG. 1. The method can include the following step 610.

[0064] In step 610, the terminal device determines that the first resource is included in the first uplink transmission resource, the first uplink transmission resource is one of N uplink transmission resources, and the first resource is not used for uplink transmission, where N is a positive integer.

[0065] The uplink transmission resource refers to a resource used for uplink transmission by the terminal device. The resource can include a time domain resource and a frequency domain resource. In some embodiments, the number of uplink transmission resources configured or scheduled for the terminal device is N, where N can be 1 or an integer greater than 1.

[0066] In some embodiments, one of the N uplink transmission resources corresponds to any of the following: one uplink channel (such as a PUSCH (Physical Uplink Shared Channel)), one transmission occasion, one resource occupied by a transport block (TB), multiple resources occupied by transport blocks, or one resource occupied by a transport block in one time domain unit.

[0067] In some embodiments, the N uplink transmission resources do not overlap in the time domain and / or do not overlap in the frequency domain. For any two of the N uplink transmission resources, the two uplink transmission resources do not overlap in the time domain and / or do not overlap in the frequency domain.

[0068] The first uplink transmission resource is one of the N uplink transmission resources. The manner of determining the first uplink transmission resource from the N uplink transmission resources can be understood from the description of the embodiments below.

[0069] The first resource is all or part of the first uplink transmission resource. In some embodiments, the first resource is part of the first uplink transmission resource. The first resource is not used for uplink transmission. It can be understood that the first resource is not used for uplink transmission, which means that the first resource enables uplink resource muting, and the terminal device does not use the first resource for uplink transmission.

[0070] The terminal device does not use the first resource for uplink transmission after determining that the first resource is included in the first uplink transmission resource. The terminal device can use other resources in the first uplink transmission resource except the first resource for uplink transmission, but the terminal device does not use the first resource for uplink transmission. Since the terminal device does not use the first resource for uplink transmission, the network device can measure the CLI of the adjacent network device at the location of the first resource, thereby improving the problem of weakening of uplink coverage caused by the CLI between network devices, and improving the accuracy and reliability of uplink reception.

[0071] Next, the determination manner of the time-frequency location of the first resource is introduced and described.

[0072] In some embodiments, the terminal device receives indication information of the first resource, and the indication information is used to indicate the time-frequency location of the first resource in the first uplink transmission resource.

[0073] In some embodiments, the network device sends the indication information of the first resource, and accordingly, the terminal device receives the indication information of the first resource sent by the network device. In the embodiments of the present application, the manner in which the network device sends the indication information of the first resource is not limited, which can be in the form of unicast, multicast or broadcast. Based on the indication information of the first resource, the terminal device can determine the time-frequency location of the first resource in the first uplink transmission resource, thereby realizing not using the first resource for uplink transmission.

[0074] In some embodiments, the indication information of the first resource can be carried in high-layer signaling, such as RRC (Radio Resource Control) signaling or MAC CE (Media Access Control Control Element) signaling, and the indication information of the first resource can also be carried in DCI (Downlink Control Information).

[0075] In some embodiments, the indication information of the first resource includes at least one of the following: first time domain information and first frequency domain information. The first time domain information is used to indicate the time domain location of the first resource, and the first frequency domain information is used to indicate the frequency domain location of the first resource.

[0076] Before the following content is introduced and described, it is first necessary to explain that, in the present application, except for special description, the time domain unit refers to a time slot (slot), the time domain sub-unit refers to a symbol (symbol), the frequency domain unit refers to a resource block (RB), and the frequency domain sub-unit refers to an RE.

[0077] In some embodiments, the time domain location of the first resource is determined based on a first time domain reference point. In some embodiments, the first time domain information is used to indicate the time domain location of the first resource determined based on the first time domain reference point. The first time domain reference point is a reference position in time domain, which can be pre-agreed or indicated by the network device to the terminal device.

The time domain location of the first DMRS contained in the first uplink transmission resource refers to the symbol where the first DMRS contained in the first uplink transmission resource is located. The time domain locations of the multiple DMRSs respectively contained in the first uplink transmission resource refer to the symbols where the multiple DMRSs respectively contained in the first uplink transmission resource are located.

[0080] In some embodiments, the above-mentioned time domain unit can be time slot level, and the time domain location can be symbol level.

The time domain location of the first DMRS on the time domain unit in the first uplink transmission resource refers to the symbol where the first DMRS on a time slot in the first uplink transmission resource is located. The time domain locations of the multiple DMRSs respectively on the time domain unit in the first uplink transmission resource refer to the symbols where the multiple DMRSs respectively on a time slot in the first uplink transmission resource are located.

[0081] In some embodiments, the frequency domain location of the first resource is determined based on a first frequency domain reference point. In some embodiments, the first frequency domain information is used to indicate the frequency domain location of the first resource determined based on the first frequency domain reference point. The first frequency domain reference point is a reference position in frequency domain, which can be pre-agreed or indicated by the network device to the terminal device. Illustratively, the first frequency domain reference point can be indicated in the first frequency domain information.

[0082] In some embodiments, the first frequency domain reference point is any one of: a starting frequency domain position of the first uplink transmission resource, a starting frequency domain position on one time domain unit in the first uplink transmission resource.

[0083] In some embodiments, the above frequency domain position can be RB level. The starting frequency domain position of the first uplink transmission resource refers to a starting RB of the first uplink transmission resource.

[0084] In some embodiments, the above time domain unit can be slot level, and the frequency domain position can be RB level. The starting frequency domain position on one time domain unit in the first uplink transmission resource refers to a starting RB on one slot in the first uplink transmission resource.

[0085] In some embodiments, the first resource occupies one or more time domain sub-units continuously or discretely in the time domain. In some embodiments, the above time domain sub-unit can be symbol level, and the first resource occupies one or more symbols continuously or discretely in the time domain.

[0086] For example, the first resource occupies one symbol in the time domain. For example, the first resource occupies multiple symbols continuously in the time domain, that is, the first resource occupies multiple symbols in the time domain, and the multiple symbols are continuous, and there is no time domain interval between any two symbols in the multiple symbols. For example, the first resource occupies multiple symbols discretely in the time domain, that is, the first resource occupies multiple symbols in the time domain, and the multiple symbols are non-continuous, and there is at least a time domain interval between two symbols in the multiple symbols.

[0087] In some embodiments, the first resource occupies one or more frequency domain units continuously or discretely in the frequency domain within the system full bandwidth or sub-band, and one or more frequency domain sub-units. In some embodiments, the above frequency domain unit can be RB level, and the above frequency domain sub-unit can be RE level. The first resource occupies one or more RBs continuously or discretely in the frequency domain within the system full bandwidth or sub-band, and one or more REs.

[0089] The continuous multiple RBs refer to that there is no frequency domain interval between any two RBs in the multiple RBs, and the discrete multiple RBs refer to that there is a frequency domain interval between at least two RBs in the multiple RBs. The continuous multiple REs refer to that there is no frequency domain interval between any two REs in the multiple REs, and the discrete multiple REs refer to that there is a frequency domain interval between at least two REs in the multiple REs.

[0090] In some embodiments, the first time domain information includes at least one of the following: indexes of one or more time domain subunits, an index of a starting time domain subunit, a length or a quantity of time domain subunits, a bitmap of time domain subunit mapping, and an interval value of comb mapping of time domain subunits. It should be understood that the length of time domain subunits and the quantity of time domain subunits mean the same, both referring to the number of occupied time domain subunits.

[0091] In some embodiments, the time domain subunit can be at a symbol level. The first time domain information includes at least one of the following: indexes of one or more symbols, an index of a starting symbol, a length or a quantity of symbols, a bitmap of symbol mapping, and an interval value of comb mapping of symbols.

[0092] Exemplarily, the first time domain information comprises indexes of one or more symbols.

For example, the first resource occupies three symbols with indexes of 0, 2, 8, and the first time domain information comprises indexes of the three symbols, i.e., 0, 2, 8.

[0093] Exemplarily, the first time domain information comprises an index of a starting symbol, and a length or a number of symbols. That is, the first time domain information comprises an index of a starting symbol of the first resource, and a length or a number of symbols of the first resource. This mode can be used for indicating one or more continuous symbols occupied by the first resource. For example, the first resource occupies three continuous symbols with a starting symbol index of 1, and the first time domain information comprises the starting symbol index 1 and the length or the number of symbols 3.

[0095] Exemplarily, the first time domain information comprises an interval value of comb-shaped symbol mapping. That is, the first time domain information comprises an interval value of comb-shaped symbols occupied by the first resource, which represents a number of symbols between two adjacent symbols in the comb-shaped symbols, or a difference between index values of two adjacent symbols. For example, the first resource occupies comb-shaped symbols with indexes of 0, 4, 8, 12 in a time slot, and when the interval value represents a number of symbols between two adjacent symbols in the comb-shaped symbols, the interval value is 3; when the interval value represents a difference between index values of two adjacent symbols in the comb-shaped symbols, the interval value is 4. Optionally, the first time domain information comprises an index of a starting symbol in addition to the interval value of comb-shaped symbol mapping.

[0096] In some embodiments, a number of time domain subunits occupied by the first resource is related to a number of time domain subunits contained in the first uplink transmission resource, or a number of time domain subunits occupied by DMRS in the first uplink transmission resource, or indicated by the first time domain information.

[0097] Exemplarily, the number of time domain subunits occupied by the first resource has a positive correlation with the number of time domain subunits contained in the first uplink transmission resource. The more the number of time domain subunits contained in the first uplink transmission resource, the more the number of time domain subunits occupied by the first resource; on the contrary, the less the number of time domain subunits contained in the first uplink transmission resource, the less the number of time domain subunits occupied by the first resource.

[0098] Exemplarily, the number of time domain subunits occupied by the first resource has a positive correlation with the number of time domain subunits occupied by DMRS in the first uplink transmission resource. The more the number of time domain subunits occupied by DMRS in the first uplink transmission resource, the more the number of time domain subunits occupied by the first resource; on the contrary, the less the number of time domain subunits occupied by DMRS in the first uplink transmission resource, the less the number of time domain subunits occupied by the first resource.

[0102] In some embodiments, the network device can configure the time-frequency pattern of the first resource which needs to be enabled for muting when PUSCH transmission through RRC signaling. FIG. 7, FIG. 8 and FIG. 9 show the schematic diagrams of several time-frequency patterns of the first resource. In FIG. 7, FIG. 8 and FIG. 9, each square represents one RE, the square filled with dots in the figure represents the RE occupied by PUSCH, the square filled with black represents the RE occupied by DMRS, and the square filled with white and marked with × represents the RE occupied by the first resource.

[0103] In some embodiments, the symbol occupied by the first resource is placed at the front end of the first uplink transmission resource. As shown in FIG. 7, FIG. 8 and FIG. 9, the symbol occupied by the first resource is placed at the front end of PUSCH, which is beneficial for obtaining the interference covariance matrix in time for the receiver to process.

[0104] In some embodiments, as shown in FIG. 7, FIG. 8 and FIG. 9, the first resource can also be placed around the DMRS, which is beneficial for forming accurate channel estimation. In FIG. 7, if the network device configures or the protocol agrees to take the starting symbol of PUSCH as the reference point, the symbol occupied by the muted first resource can be configured with a time domain symbol index of 3 and a symbol number of 1, or a bit map of 000100 indicating that the fourth symbol is occupied in the first six symbols of PUSCH. In addition, there is another possible implementation manner that taking the DMRS or the first DMRS symbol in PUSCH as the reference point, the symbol occupied by the first resource can be the first symbol after the DMRS, or can be placed in a certain symbol before the DMRS.

[0105] Considering that the interference situation in the PUSCH will change when the PUSCH is long, the number of symbols occupied by the first resource can be configured according to the length of the PUSCH, for example, 1 first resource occupation symbol is configured when the number of PUSCH symbols is less than 7, and 2 first resource occupation symbols are configured otherwise, as shown in FIG. 8. The specific symbol position can be determined by offset or symbol index. Further considering that the multiple DMRS is also set to accurately capture the changing channel in a slot, it is also necessary and beneficial to channel estimation to set the mute resource according to the number of DMRSs to obtain the interference covariance on multiple symbols, as shown in FIG. 9. The mute resource occupation symbols around each DMRS are optionally distributed before or after the DMRS symbol.

[0106] As shown in FIG. 10, the bandwidth size of the first resource configuration is limited by the bandwidth occupied by the slot type PUSCH itself, for example, with reference to the PUSCH frequency domain starting position, the length of the bandwidth or sub-bandwidth also needs to conform to the uplink channel configuration under the slot type. In addition, considering that the first resource configuration will cause the uplink transmission resource to decrease, part of the RBs in the bandwidth can also be selected for the first resource configuration, which can be concentrated or distributed, and can be located at the bandwidth edge or center. For the configuration of the subcarriers or REs inside the bandwidth, FIGS. 7, 8 and 9 exemplarily show the setting of the comb format 2 and the offset 1, which is only one implementation manner. The first resource can also be configured to occupy multiple continuous REs.

[0107] In the above manner, the time-frequency position of the first resource in the first uplink transmission resource can be flexibly and clearly configured by using the indication information of the first resource.

[0108] In the following, several possible cases of determining the first uplink transmission resource are introduced and described.

[0109] Case 1: The number of the first uplink transmission resources is M, and M is a positive integer less than N.

[0110] In this case, among the N uplink transmission resources configured or scheduled to the terminal device, part of the uplink transmission resources are the first uplink transmission resources. For each first uplink transmission resource, the terminal device can determine the first resource included in the first uplink transmission resource by using the method provided in the above embodiments. The first resource enables the uplink resource muting. That is, among the N uplink transmission resources configured or scheduled to the terminal device, the terminal device enables the uplink resource muting only in part of the uplink transmission resources.

[0111] In some embodiments, among the M first uplink transmission resources, the time domain position of the first uplink transmission resource is the earliest one in the N uplink transmission resources.

[0112] In some embodiments, when M equals 1, the number of the first uplink transmission resources is 1. That is, among the N uplink transmission resources, 1 first uplink transmission resource enables uplink resource muting. In some embodiments, the 1 first uplink transmission resource is the uplink transmission resource with the earliest time domain position among the N uplink transmission resources, which can also be referred to as the 1st uplink transmission resource.

[0113] In some embodiments, when M is greater than 1, the number of the first uplink transmission resources is M, and the M first uplink transmission resources can be consecutive M uplink transmission resources or discrete M uplink transmission resources among the N uplink transmission resources. In some embodiments, the M first uplink transmission resources include the uplink transmission resource with the earliest time domain position among the N uplink transmission resources, which can also be referred to as the 1st uplink transmission resource.

[0114] In some embodiments, the M first uplink transmission resources are indicated in the form of a bit map.

[0115] For example, 3 uplink transmission resources are configured or scheduled for the terminal device, and the bit map corresponding to the first uplink transmission resource is 100, which represents that among the 3 uplink transmission resources, the 1st uplink transmission resource is the first uplink transmission resource (i.e., the uplink transmission resource enabling uplink resource muting), and the 2nd and 3rd uplink transmission resources are not the first uplink transmission resource.

[0116] In some embodiments, the M first uplink transmission resources are indicated in the form of offset information, which is used to indicate the position offset of the first uplink transmission resource relative to a reference uplink transmission resource.

[0117] For example, the reference uplink transmission resource can be the 1st uplink transmission resource among the N uplink transmission resources. For example, 3 uplink transmission resources are configured or scheduled for the terminal device, and the offset information corresponding to the first uplink transmission resource is 0, which represents that among the 3 uplink transmission resources, the 1st uplink transmission resource is the first uplink transmission resource (i.e., the uplink transmission resource enabling uplink resource muting), and the 2nd and 3rd uplink transmission resources are not the first uplink transmission resource. For another example, 3 uplink transmission resources are configured or scheduled for the terminal device, and the offset information corresponding to the first uplink transmission resource is 0 and 2, which represents that among the 3 uplink transmission resources, the 1st and 3rd uplink transmission resources are the first uplink transmission resource (i.e., the uplink transmission resource enabling uplink resource muting), and the 2nd uplink transmission resource is not the first uplink transmission resource.

[0118] In some embodiments, the above uplink transmission resource is a time domain unit for transmitting an uplink channel, which can be a PUSCH. The terminal device is configured or scheduled to transmit the uplink channel using N time domain units.

[0119] In some embodiments, the terminal device is configured or scheduled to transmit one uplink channel using N time domain units. Taking time domain units as time slots as an example, the terminal device is configured or scheduled to transmit one uplink channel using N time slots. This scheme is applicable to the cases of PUSCH repetition and TB processing over multi-slot.

[0120] In some embodiments, the terminal device is configured or scheduled to transmit multiple uplink channels using N time domain units. Taking time domain units as time slots as an example, the terminal device is configured or scheduled to transmit multiple uplink channels using N time slots. This scheme is applicable to the case of multi-PUSCH scheduling.

[0121] In some embodiments, the network device can configure the first resource in the uplink channel that needs to be enabled for muting through RRC signaling, and when the network device schedules N time slots for PUSCH transmission through DCI signaling, only enable the first resource muting in the uplink channel transmission of part of the time slots, where scheduling N time slots for PUSCH transmission refers to scheduling N time slots for PUSCH repetition of different redundancy versions of the same transport block, or multi-PUSCH scheduling of different transport blocks, or TB processing over multi-slots of the same transport block, or scheduling l times of transport blocks that need N time slots for transmission. Since the time interval of the N time slots is short, when the external interference situation is stable, interference measurement can be performed on only one or a few time slots to grasp the interference situation, without occupying too many uplink channel resources, reducing the loss of uplink throughput.

[0122] Exemplarily, when N = 4, as shown in FIG. 11, it is considered that the 4 time slots in which the PUSCH can be transmitted must be of the same time slot type or can be of different time slot types, and when a time slot in which the PUSCH cannot be transmitted is encountered, whether the time slot is directly discarded or postponed until 4 time slots in which the PUSCH can be transmitted, the time slots in which the PUSCH is actually transmitted can have the following combinations: 1) 1, 2, 3, 4; 2) 1, 2, 3; 3) 1, 2, 3, 5. At this time, the time slot in which the first resource is enabled to be silent can be one or more. If it is one, the first resource is enabled to be used for demodulation of the subsequent PUSCH only at the starting position of the continuous time slot, for example, time slot 1 in the figure. If it is more, the first resource can be enabled to be silent in continuous or discrete selected time slots. A typical implementation is that, for example, time slot 1 and time slot 5 are selected to enable the first resource to be silent in combination 3. When continuous time slots or time slots with a time domain span less than a certain threshold are encountered, the starting time slot is selected to enable the first resource to be silent, and the remaining discrete time slots or time slots with a time domain span greater than a certain threshold all need to enable the first resource to be silent.

[0123] It is considered that the starting symbol of the uplink channel transmission in the selected time slot can be the same (as shown in FIG. 12, subgraph (a)) or different (as shown in FIG. 12, subgraph (b)). When the first resource is configured, a typical implementation is to take the starting symbol of the uplink channel transmission in the selected time slot as a reference point to configure the time-frequency configuration of the first resource in the time slot, that is, to define a plurality of first resources on different time slots of the transmitted uplink channel. In addition, taking the starting symbol of the uplink channel in the first time slot in which the uplink channel is transmitted in N time slots as a reference point is also a realizable manner, that is, taking the starting symbol of the uplink channel in the starting time slot as a reference point to define a first resource on multiple time slots.

[0124] This method can be applied to the case where a plurality of time slots are configured at one time to transmit the uplink channel, such as PUSCH repetition, multi-PUSCH scheduling, and TB processing over multi-slot. In order to reduce resource waste, when the external interference situation is stable, the interference situations faced by continuous uplink time slots are similar, so only the interference on part of the time slots needs to be estimated in a coarse-grained manner, without occupying too many uplink channel resources, reducing the loss of uplink throughput.

[0125] Case 2: The first uplink transmission resource is an uplink transmission resource that overlaps or partially overlaps with a preconfigured silent resource, and the silent resource is used for interference measurement by the network device.

[0126] The mute resource refers to a pre-configured resource used by the network device for interference measurement. In some embodiments, the mute resource is repeatedly configured with K first time units as a period, where K is a positive integer. That is, the mute resource is a periodic resource. The unit of the first time unit is any one of the following: seconds, milliseconds, frames, subframes, slots, symbols.

[0127] In this case, for any one of the N uplink transmission resources configured or scheduled to the terminal device, if the uplink transmission resource overlaps or partially overlaps with the pre-configured mute resource, the uplink transmission resource is determined as a first uplink transmission resource that needs to enable uplink resource muting. The terminal device can determine a first resource included in the first uplink transmission resource by using the method provided in the above embodiments, and the first resource enables uplink resource muting. In addition, if the uplink transmission resource does not overlap with the pre-configured mute resource, the uplink transmission resource does not need to enable uplink resource muting.

[0128] In some embodiments, the configuration information of the mute resource includes at least one of the following: period information, second time domain information, and second frequency domain information. The period information is used to indicate the period of the mute resource. The second time domain information is used to indicate the time domain position of the mute resource in the period. The second frequency domain information is used to indicate the frequency domain position of the mute resource in the period.

[0129] In some embodiments, in the case where the mute resource is not a periodic resource, the configuration information of the mute resource can include at least one of the following: third time domain information and third frequency domain information. The third time domain information is used to indicate the time domain position of the mute resource. The third frequency domain information is used to indicate the frequency domain position of the mute resource.

[0130] In some embodiments, the time domain position of the mute resource in the period is determined based on a second time domain reference point. In some embodiments, the second time domain information is used to indicate the time domain position of the mute resource in the period determined based on the second time domain reference point. The second time domain reference point is a reference position in the time domain, which can be pre-agreed or indicated by the network device to the terminal device. For example, the second time domain reference point can be indicated in the second time domain information.

[0131] In some embodiments, the second time domain reference point is any one of the following: a starting time domain position of the first time unit, and a starting time domain position of a time domain unit.

[0132] In some embodiments, the time domain position described above can be at the symbol level. The starting time domain position of the first time unit refers to the starting symbol of the first time unit. The starting time domain position of a time domain unit refers to the starting symbol of the time domain unit, such as the starting symbol of a slot. In some embodiments, the second time domain indication information includes one or more offset information, which is used to indicate one or more time domain positions occupied by the mute resource in the period. The offset information represents the offset between the time domain position occupied by the mute resource in the period and the second time domain reference point. In combination with the second time domain reference point and the offset information, the time domain position occupied by the mute resource in the period can be determined.

[0133] In some embodiments, the frequency domain position of the mute resource in the period is determined based on a second frequency domain reference point. In some embodiments, the second frequency domain information is used to indicate the frequency domain position of the mute resource in the period determined based on the second frequency domain reference point. The second frequency domain reference point is a reference position in the frequency domain. The second frequency domain reference point can be pre-agreed or indicated by the network device to the terminal device. For example, the second frequency domain reference point can be indicated in the second frequency domain information.

[0134] In some embodiments, the second frequency domain reference point is any one of the following: a starting frequency domain position of a system bandwidth, a frequency domain position of a common resource block.

[0135] In some embodiments, the frequency domain position described above can be at the RB level. The starting frequency domain position of the system bandwidth refers to the starting RB of the system bandwidth. The frequency domain position of the common resource block refers to the RB occupied by the common resource block.

[0136] In some embodiments, the reference starting position of the period of the mute resource can be SFN0 (System Frame Number), or a certain time domain offset from SFN0 or a certain first time unit. The present application does not limit this.

[0137] In some embodiments, in each period, the mute resource occupies one or more continuous or discrete time domain units in the time domain, or the mute resource occupies one or more continuous or discrete time domain sub-units in the time domain.

[0138] In some embodiments, the time domain unit described above can be at the slot level, and the time domain sub-unit can be at the symbol level. In each period, the mute resource occupies one or more continuous or discrete slots in the time domain, or the mute resource occupies one or more continuous or discrete symbols in the time domain.

[0139] Exemplarily, in each cycle, the quiet resource occupies one time slot in the time domain. Exemplarily, in each cycle, the quiet resource occupies a plurality of time slots in the time domain. That is, in each cycle, the quiet resource occupies a plurality of time slots in the time domain, and the plurality of time slots are continuous, and there is no time domain interval between any two time slots in the plurality of time slots. Exemplarily, in each cycle, the quiet resource occupies a plurality of time slots in the time domain. That is, in each cycle, the quiet resource occupies a plurality of time slots in the time domain, and the plurality of time slots are discrete, and there is a time domain interval between at least two time slots in the plurality of time slots. Exemplarily, in each cycle, the quiet resource occupies one symbol in the time domain. Exemplarily, in each cycle, the quiet resource occupies a plurality of symbols in the time domain. That is, in each cycle, the quiet resource occupies a plurality of symbols in the time domain, and the plurality of symbols are continuous, and there is no time domain interval between any two symbols in the plurality of symbols. Exemplarily, in each cycle, the quiet resource occupies a plurality of symbols in the time domain. That is, in each cycle, the quiet resource occupies a plurality of symbols in the time domain, and the plurality of symbols are discrete, and there is a time domain interval between at least two symbols in the plurality of symbols.

[0140] In some embodiments, in each cycle, the quiet resource occupies one or more frequency domain units or one or more frequency domain sub-units in the frequency domain within the system full bandwidth or sub-band, which are continuous or discrete. In some embodiments, the above-mentioned frequency domain unit can be RB level, and the above-mentioned frequency domain sub-unit can be RE level, and in each cycle, the quiet resource occupies one or more RBs or one or more REs in the frequency domain within the system full bandwidth or sub-band, which are continuous or discrete.

[0141] Exemplarily, in each cycle, the mute resource occupies one RE on one RB in the whole bandwidth in the frequency domain. Exemplarily, in each cycle, the mute resource occupies continuous multiple REs on one RB in the whole bandwidth in the frequency domain. Exemplarily, in each cycle, the mute resource occupies discrete multiple REs on one RB in the whole bandwidth in the frequency domain. Exemplarily, in each cycle, the mute resource occupies continuous multiple REs on continuous multiple RBs in the whole bandwidth in the frequency domain. Exemplarily, in each cycle, the mute resource occupies discrete multiple REs on discrete multiple RBs in the whole bandwidth in the frequency domain. Exemplarily, in each cycle, the mute resource occupies one RE on one RB in a sub-band in the frequency domain. Exemplarily, in each cycle, the mute resource occupies continuous multiple REs on one RB in a sub-band in the frequency domain. Exemplarily, in each cycle, the mute resource occupies discrete multiple REs on one RB in a sub-band in the frequency domain. Exemplarily, in each cycle, the mute resource occupies continuous multiple REs on continuous multiple RBs in a sub-band in the frequency domain. Exemplarily, in each cycle, the mute resource occupies discrete multiple REs on discrete multiple RBs in a sub-band in the frequency domain.

[0142] The continuous multiple RBs refer to that there is no frequency domain interval between any two RBs in the multiple RBs, and the discrete multiple RBs refer to that there is at least a frequency domain interval between any two RBs in the multiple RBs. The continuous multiple REs refer to that there is no frequency domain interval between any two REs in the multiple REs, and the discrete multiple REs refer to that there is at least a frequency domain interval between any two REs in the multiple REs.

[0143] In some embodiments, the time domain position of the mute resource in the cycle is related to the type of the time domain unit contained in the cycle. The time domain unit has multiple types, including uplink time domain units, SBFD time domain units, and the like.

[0144] In some embodiments, the time domain position of the mute resource in the cycle includes: the time domain position occupied by the time domain unit of the first type contained in the cycle; or the time domain position occupied by part of the time domain units in the multiple continuous time domain units of the first type contained in the cycle; wherein the time domain unit has multiple types, and the first type is one or at least two of the multiple types.

[0145] In some embodiments, the network device can pre-configure the periodicity of the mute resource through RRC signaling, with K first time units as a period, which can be seconds (s), milliseconds (ms), frames, subframes, or slots. The configuration can have various forms, and finally fall into m*K slots, where m is the number of slots included in a first time unit. In a period, the mute resource can be configured on one or more slots according to the slot type, and the slot position of the mute resource can be configured through slot type definition, offset, and bitmap.

[0146] A typical implementation is that once the uplink transmission resource appears in the pre-configured slot position of the mute resource, the uplink transmission resource is determined as the first uplink transmission resource, and the first resource in the first uplink transmission resource is enabled for uplink muting according to the method given in the above embodiments.

[0147] Figure 13 shows several examples of mute pattern configuration according to slot type in a period. The black dashed box in the figure is a schematic diagram of the bandwidth that the mute resource can occupy. In actuality, the RBs that are continuously or discretely occupied can be defined. Subfigure (a) shows that mute resources are configured only in each SBFD slot. Subfigure (b) shows that mute resources are configured only in each uplink slot. Subfigure (c) shows that mute resources are configured in each SBFD slot and uplink slot. Subfigure (d) shows a scheme in which, when N SBFD slots or uplink slots appear continuously, the mute resource configuration can be optimized to reduce the impact on uplink throughput due to stable external interference. In the figure, N is 2. Once two continuous uplink transmission resources appear, mute resources are configured in one of them. The mute resource can be configured at any position at the beginning / middle / end of the N slots through offset definition.

[0148] Further, the network device can also configure the specific time-frequency pattern of the mute resource in some slot positions through signaling. This gives another implementation. If the uplink transmission resource overlaps with the time-frequency pattern, the uplink transmission resource is determined as the first uplink transmission resource, and the first resource in the first uplink transmission resource is enabled for uplink muting according to the method given in the above embodiments, as shown in the second slot in Figure 14. If the uplink transmission resource does not overlap with the time-frequency pattern, the uplink channel transmission does not enable uplink resource muting, and only interference measurement is performed in the pre-configured mute resource time-frequency pattern, as shown in the ninth slot in Figure 14.

[0149] By the above method, when the pre-configured mute resource does not overlap with the uplink transmission resource, the network device can measure the interference by itself, and accurately grasp the interference at that time; when the pre-configured mute resource overlaps or partially overlaps with the uplink transmission resource, part of the resources in the uplink transmission resource needs to be muted to perform uplink measurement. However, if only the overlapping part of the resource is muted, the mute resources on different uplink transmission resources will be different, the signal processing difficulty will increase, and different mute resource patterns will also require a large amount of test verification, bringing extremely high complexity. Therefore, it is also necessary to ensure that the mute resources in different uplink transmission resources are the same. The method provided in the present application enables the first resource in the uplink transmission resource to be muted when the pre-configured mute resource overlaps or partially overlaps with the uplink transmission resource, so as to ensure that the mute resources on different uplink transmission resources are the same, thereby avoiding the above problems.

[0150] Case 3: The first uplink transmission resource is an uplink transmission resource not used for transmitting the first control information, and the first control information at least includes HARQ-ACK (Hybrid Automatic Repeat request-acknowledgement) information.

[0151] In this case, for any one of the N uplink transmission resources configured or scheduled to the terminal device, if the uplink transmission resource is used for transmitting the first control information (such as HARQ-ACK information), the uplink resource in the uplink transmission resource is not enabled to be muted, thereby avoiding the influence on transmitting the first control information and ensuring that the first control information can be successfully transmitted. If the uplink transmission resource is not used for transmitting the first control information, the method provided in the above embodiment can be used to determine the first resource included in the first uplink transmission resource, and the first resource enables the uplink resource to be muted.

[0152] By the above method, for the uplink transmission resource used for transmitting the first control information, the uplink resource is not enabled to be muted, which can ensure that some important control information is successfully transmitted.

[0153] In some embodiments, case 1 and case 2 can be combined. The terminal device determines M first uplink transmission resources from the N uplink transmission resources, and the first uplink transmission resources overlap or partially overlap with the pre-configured mute resource.
