Description

Method, device and storage medium for sending uplink information TECHNICAL FIELD

[0001] Embodiments of the present application relate to the field of communication technology, in particular to a method for sending uplink information, a device and a storage medium. BACKGROUND

[0002] 3GPP (3rd Generation Partnership Project) introduces a sub-band non-overlapping full duplex (SBFD) technology in a 5G NR (New Radio) system to overcome the problem of weak uplink coverage, large uplink delay and insufficient uplink capacity caused by less uplink resource allocation in time division duplex (TDD), that is, data can be transmitted and received simultaneously on different sub-bands of the same subframe / slot / symbol.

[0003] The duplex technology faces the problem of cross link interference (CLI) between base stations, that is, in the case that adjacent base stations are configured with different transmission directions or the adjacent base stations simultaneously receive uplink information and transmit downlink information in the SBFD slot, the base station receiving uplink data will be interfered by the downlink transmission of the adjacent base station due to the large downlink transmission power of the base station. In the related art, the interference signal is evaluated by using part of the uplink resources to facilitate the enhanced design of the receiver; in order to accurately estimate the channel, the silent resources need to be configured around the demodulation reference signal (DMRS).

[0004] However, the introduction of the silent resources will make the resource elements (REs) originally used for transmitting uplink control information unable to perform uplink transmission. Therefore, in the case of evaluating the channel by using the silent resources, how to solve the conflict between the silent resources and the resources used for transmitting uplink information is a problem to be solved.

[0052] In order to make the purposes, technical solutions and advantages of the present application clearer, the following further describes the embodiments of the present application with reference to the accompanying drawings.

[0053] Firstly, the terms involved in the embodiments of the present application are introduced:

[0054] SBFD: In order to overcome the problems of weak uplink coverage, large uplink delay and insufficient uplink capacity caused by the small number of uplink resource allocations in NR TDD, 3GPP introduces the SBFD technology in R18, that is, data can be simultaneously transmitted and received on different subbands of the same subframe / slot / symbol. This technology is mainly used on the base station side, and the terminal side still maintains the current state, that is, only uplink data transmission or downlink data reception is supported in one subframe / slot / symbol. As shown in FIG. 1, an uplink (UL) subband is configured in a downlink (DL) subframe / slot / symbol or a flexible subframe / slot / symbol. As shown in FIG. 1(a), the middle subband of a DL subframe / slot / symbol or a flexible subframe / slot / symbol is configured as an uplink subband; as shown in FIG. 1(b), the lower half subband of a DL subframe / slot / symbol or a flexible subframe / slot / symbol is configured as an uplink subband; the present application does not limit the manner of configuring the uplink subband.

[0055] In the related art, the SBFD subband (uplink subband and / or downlink subband) is configured on the downlink symbol (DL symbol) and / or flexible symbol configured in TDD-UL-DL-ConfigCommon. FIG. 2 shows a possible frame structure, as shown in the figure, the uplink subband is configured on multiple downlink symbols.

[0056] However, the SBFD technology faces the CLI problem between base stations caused by the flexibility of uplink and downlink configurations, that is, when adjacent base stations configure different transmission directions or adjacent base stations simultaneously receive uplink data and transmit downlink data in the SBFD slot, the base station receiving uplink data will be interfered by the downlink transmission of the adjacent base station due to the extremely large downlink transmission power of the base station.

[0057] Muting resource: uplink resource muting is a solution proposed to cope with SBFD CLI. Specifically, 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 enhanced base station receiver can effectively improve the problem of uplink coverage weakening caused by the CLI between base stations. An uplink resource muting time-frequency domain resource configuration mode is shown in FIG. 3. In FIG. 3, the black block represents DMRS, the diagonal shadow block represents muted RE, and the white block represents PUSCH. As shown in the figure, when muting resources are used to measure CLI interference, in order to accurately estimate the channel, the muted resources need to be configured around the DMRS.

[0058] However, the configuration of the muted resource will make the original RE that can transmit the uplink control information or data in the PUSCH unable to perform uplink transmission. For example, in order to ensure demodulation accuracy, the protocol stipulates that the HARQ-ACK information in the uplink control information is mapped from the first symbol after the DMRS, and in the case of configuring the muted resource around the DMRS to measure the CLI, the muted resource and the resource for transmitting the uplink control signal or data are in conflict. In this case, how to use a reasonable mapping rule to avoid the conflict between the two resources is a problem to be solved.

[0059] The communication system and service scenario described in the embodiments of the present application are used to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those skilled in the art can know that, with the evolution of the communication system and the appearance of new service scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0060] Please refer to FIG. 4, which shows a schematic diagram of a communication system provided by an embodiment of the present application. The communication system can include a network device 10 and a terminal 20.

[0061] The network device 10 is a device deployed in an access network to provide wireless communication functions for the terminal 20. The network device 10 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 network device functions can be different, for example, in a 5G NR system, it is called gNodeB or gNB. As the communication technology evolves, the name of the "base station" can change. For ease of description, in the embodiments of the present application, the above-mentioned devices providing wireless communication functions for the terminal 20 are collectively referred to as network devices.

[0062] The terminal 20 involved in the embodiments of the present application can include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to wireless modems, and various forms of user equipment (User Equipment, UE), mobile stations (Mobile Station, MS), terminal devices, and the like. For ease of description, in the embodiments of the present application, the above-mentioned devices are collectively referred to as terminals.

[0063] The network device 10 is a device for providing wireless communication services for the terminal 20. The network device 10 and the terminal 20 can establish a connection through an air interface, so as to communicate through the connection, including the interaction of signaling and data. The number of network devices 10 can be multiple, and two adjacent network devices 10 can also communicate through wired or wireless means. The terminal 20 can switch between different network devices 10, that is, establish a connection with different network devices 10.

[0064] In some embodiments, the terminal 20 sends first information to the network device 10, the first information being uplink control information or uplink data, the first information being sent through a first resource in a first uplink channel, and the first information being mapped and transmitted on resources other than enabled mute resources in the first uplink channel.

[0065] In some embodiments, the terminal 20 receives first signaling sent by the network device 10, the first signaling being used to indicate the time domain configuration and / or frequency domain configuration of the mute resource in the first uplink channel, the first signaling being high layer signaling or downlink control signaling.

[0066] In some embodiments, the network device 10 can also be replaced by another terminal 20, for example, in a sidelink communication system for communication between two terminals.

[0067] It should be noted that the "5G NR system" in the embodiments of the present disclosure can also be referred to as a 5G system or an NR system, but those skilled in the art can understand its meaning. The technical solutions described in the embodiments of the present disclosure can be applicable to the 5G NR system, and can also be applicable to the subsequent evolution system of the 5G NR system.

[0068] In the following, the technical solutions of the present application will be described in conjunction with several exemplary embodiments.

[0069] Please refer to FIG. 5, which shows a flow chart of the method for transmitting uplink information provided by an embodiment of the present application. The method can be applied to the communication system shown in FIG. 4 and is executed by the terminal 20 in FIG. 4. The method can include the following steps:

[0070] Step 220: In the case where the first resource and the muting resource exist overlap, the first information is transmitted through the first uplink channel in the part of the first resource based on the preset rule.

[0071] The first uplink channel is an uplink channel for the terminal to transmit information or data to the network device. For example, the first uplink channel is a PUSCH or a PUCCH.

[0072] The first resource is a resource for transmitting the first uplink channel.

[0073] For example, in the case where the first resource and the muting resource exist overlap, the part of the first resource used for mapping and transmitting the first information is determined based on the preset rule; that is, in the case where the first resource and the muting resource exist conflict, the first information is transmitted through the first uplink channel in the part of the first resource based on the preset rule.

[0074] In some embodiments, the part of the first resource used for transmitting the first information does not include at least one of the resource occupied by the symbol where the DMRS is located and the resource occupied by the PTRS. For example, in the case where the PTRS is transmitted in the first uplink channel, all REs on the symbol where the DMRS is located and the REs occupied by the PTRS are not used for mapping and transmitting the first information; in the case where the PTRS is not transmitted in the first uplink channel, all REs on the symbol where the DMRS is located are not used for mapping and transmitting the first information.

[0075] The first information is uplink information sent by the terminal to the network device. In some embodiments, the first information includes HARQ-ACK information; in other embodiments, the first information includes channel state information (CSI), such as CSI part 1 and CSI part 2; in other embodiments, the first information is data, such as data transmitted on a PUSCH.

[0076] The muted resource is a resource used for channel estimation, such as measuring CLI interference, inter-base station interference, adjacent channel interference, and the like. In order to accurately perform channel estimation, the muted resource should avoid conflict with the resource for transmitting the first information, and the muted resource needs to be configured around the DMRS.

[0077] In some embodiments, the muted resource is enabled by signaling; or, the muted resource is enabled after being configured. That is, the muted resource is controlled by signaling after being configured; or, the muted resource is in an enabled state by default after being configured.

[0078] In the case where the first resource and the muted resource overlap, that is, the resource for mapping and transmitting the first information and the muted resource may conflict, the resource for transmitting the first information in the first resource needs to be determined and transmitted based on a preset rule; that is, in the case where the first resource and the muted resource overlap, the first information is transmitted in part of the first resource through a first uplink channel based on a preset rule.

[0079] In some embodiments, the part of the resource is a second resource, that is, the second resource is actually used for transmitting the first information. The preset rule includes that the second resource does not overlap with the muted resource. That is, the resource for transmitting the first information is determined in the part of the first resource that does not overlap with the muted resource. That is, the muted resource is not used for mapping or transmitting the first information; or, the muted resource cannot be used for transmitting the first information; or, the muted resource is an unusable resource for the first information.

[0080] In other embodiments, the preset rule includes that, in the case where the muted resource overlaps with a third resource, the muted resource is not enabled. The third resource is a resource in the first resource for transmitting the first information; the third resource is a pre-configured resource for transmitting the first information, or the third resource is a protocol-contracted resource for transmitting the first information.

[0081] That is, in the case where the muted resource conflicts with the resource for transmitting the first information, the muted resource is not used for channel estimation, but is used as a resource for transmitting the first information.

[0082] In some embodiments, the preset rule comprises: in a case where the muted resource overlaps with a third resource, the muted resource is enabled and the resource in the third resource that overlaps with the muted resource is not used for transmitting the first information. The third resource is a resource in the first resource used for transmitting the first information. Optionally, the third resource is a resource pre-configured for transmitting the first information, or the third resource is a resource agreed by a protocol for transmitting the first information.

[0083] That is, in a case where the muted resource conflicts with a resource used for transmitting the first information, the muted resource is enabled for channel estimation but not used for transmitting the first information. The first information is transmitted on a resource other than the muted resource in the first resource. For example, the first information is transmitted on at least one RE in the third resource that does not overlap with the muted resource; for another example, the first information is transmitted on at least one RE in a symbol other than the symbol where the muted resource is located in the first resource, such as at least one RE in a symbol after the symbol where the muted resource is located.

[0084] In some embodiments, in a case where the muted resource overlaps with a third resource, the resource used for transmitting the first information and the enabling condition of the muted resource are determined according to the priority information. The third resource is a resource in the first resource used for transmitting the first information. Optionally, the third resource is a resource pre-configured for transmitting the first information, or the third resource is a resource agreed by a protocol for transmitting the first information. For example, in a case where the muted resource overlaps with the third resource and the priority information indicates that the priority of the muted resource is lower than the priority of the third resource, the muted resource is not enabled; for another example, in a case where the muted resource overlaps with the third resource and the priority information indicates that the priority of the muted resource is higher than the priority of the third resource, the muted resource is enabled and the resource in the third resource that overlaps with the muted resource is not used for transmitting the first information. The priority information is agreed by a protocol, or the priority information is indicated by signaling.

[0085] In some embodiments, before step 220, the terminal receives first signaling sent by the network device, the first signaling being used for indicating the time domain configuration and / or the frequency domain configuration of the muted resource, the first signaling being high layer signaling or downlink control signaling. The high layer signaling refers to control and management signaling information of a network layer and above, such as Radio Resource Control (RRC) and the like; the downlink control signaling refers to control signaling sent by the network device to the terminal, including information such as Downlink Control Information (DCI) and the like. The terminal obtains the pre-configuration information of the muted resource in the first uplink channel by receiving the first signaling.

[0086] In some embodiments, the terminal receives second signaling sent by the network device, the second signaling being used for configuring the first resource, the first resource being a resource used for transmitting the first uplink channel.

[0087] In some embodiments, the terminal receives third signaling sent by the network device, the third signaling being used for configuring the third resource, the third resource being a resource configured to be used for transmitting the first information.

[0088] In some embodiments, the terminal receives fourth signaling sent by the network device, the fourth signaling being used for indicating priority information, the priority information being used for indicating a priority relationship between the mute resource and the resource used for transmitting the first information.

[0089] To sum up, the technical scheme provided by the embodiments of the present application, in the case where the first resource used for transmitting the first uplink channel and the mute resource exist overlap, determines the resource used for transmitting the first information based on the preset rule, guarantees the transmission of the first information in the first uplink channel, avoids or solves the conflict between the mute resource and the resource used for transmitting the uplink information, and improves the efficiency and reliability of the uplink information transmission.

[0090] In addition, in the method, the mute resource can be used for channel estimation, such as CLI measurement, when enabled, so that the problem of weakened uplink coverage caused by CLI between base stations can be effectively improved in the receiver of the enhanced base station, and the efficiency of the SBFD technology is improved.

[0091] In addition, based on the preset rule that the second resource and the mute resource do not exist overlap, the transmission of the first information avoids the mute resource, that is, the mute resource is excluded when the second resource used for transmitting the first information is determined, so that the erroneous transmission or missed transmission of the first information caused by the enablement of the mute resource can be avoided, and the integrity and transmission efficiency of the first information are improved.

[0092] In addition, based on the preset rule that the mute information and the first information avoid each other in the case where the mute resource and the third resource exist overlap, the enablement of the mute resource is avoided from affecting the mapping or transmission of the first information.

[0093] FIG. 6 shows an embodiment of the method for transmitting uplink information provided by an embodiment of the present application, which can be applied to the communication system shown in FIG. 4 and is executed by the terminal 20 in FIG. 4. The method can include the following steps:

[0094] Step 310: receiving first signaling;

[0095] The first signaling is used for indicating the time domain configuration and / or the frequency domain configuration of the mute resource; and after receiving the first signaling, the terminal acquires the preconfigured information of the mute resource in the first uplink channel.

[0096] In some embodiments, the first signaling is high layer signaling or downlink control signaling. The high layer signaling refers to control and management signaling information at the network layer and above, for example, the first signaling is RRC. The downlink control signaling refers to control signaling sent by the network device to the terminal, including information such as DCI.

[0097] In some embodiments, the muted resource is enabled after the first signaling is configured; in other embodiments, the muted resource is enabled or disabled by other signaling after the first signaling is configured.

[0098] For example, the terminal receives the first signaling; and the terminal obtains the configuration of the muted resource in the time domain / frequency domain from the first signaling.

[0099] In other embodiments, the terminal receives second signaling sent by the network device, and the second signaling is used to configure the first resource, which is a resource used to transmit the first uplink channel.

[0100] In other embodiments, the terminal receives third signaling sent by the network device, and the third signaling is used to configure the third resource, which is a resource configured to transmit the first information.

[0101] In other embodiments, the terminal receives fourth signaling sent by the network device, and the fourth signaling is used to indicate priority information, which is used to indicate the priority relationship between the muted resource and the resource for transmitting the first information.

[0102] Step 320: In the case where the first resource and the muted resource overlap, the first information is transmitted through the first uplink channel in part of the first resource based on a preset rule.

[0103] The first uplink channel is an uplink channel used by the terminal to transmit information or data to the network device. For example, the first uplink channel is PUSCH or PUCCH.

[0104] The first resource is a resource used to transmit the first uplink channel.

[0105] For example, in the case where the first resource and the muted resource overlap, part of the first resource is determined to be used for mapping and transmission of the first information based on a preset rule; that is, in the case where the first resource and the muted resource conflict, the first information is transmitted through the first uplink channel in part of the first resource based on a preset rule.

[0106] In some embodiments, the part of the first resource used for transmitting the first information does not include at least one of the resource occupied by the symbol where the DMRS is located and the resource occupied by the PTRS. For example, in the case where the PTRS is transmitted in the first uplink channel, neither the REs in the symbol where the DMRS is located nor the REs occupied by the PTRS are used for mapping and transmitting the first information; in the case where the PTRS is not transmitted in the first uplink channel, neither the REs in the symbol where the DMRS is located are used for mapping and transmitting the first information.

[0107] The first information is uplink information sent by the terminal to the network device. In some embodiments, the first information includes HARQ-ACK information; in other embodiments, the first information includes CSI, such as CSI part 1 and CSI part 2; in other embodiments, the first information is data, such as data transmitted on the PUSCH.

[0108] The muted resource is a resource used for channel estimation, such as measuring CLI interference; in order to accurately perform channel estimation, the muted resource should avoid conflict with the resource used for transmitting the first information, and the muted resource needs to be configured around the DMRS.

[0109] In some embodiments, the muted resource is enabled by signaling; or, the muted resource is enabled after being configured. That is, the muted resource is controlled by signaling after being configured; or, the muted resource is in an enabled state by default after being configured.

[0110] In some embodiments, the enabled muted resource is not used for mapping or transmitting the first information; or, the enabled muted resource cannot be used for transmitting the first information; or, the enabled muted resource is unavailable resource of the first information. That is, the first information is mapped and transmitted on the resource of the first resource except the enabled muted resource. That is, the first information is not transmitted on the enabled muted resource; that is, the resource used for transmitting the first information is not the enabled muted resource.

[0111] In the case where the first resource and the muted resource overlap, that is, the resource used for mapping and transmitting the first information and the muted resource may conflict, the resource used for transmitting the first information in the first resource needs to be determined and transmitted based on a preset rule; that is, in the case where the first resource and the muted resource overlap, the first information is transmitted in the part of the first resource through the first uplink channel based on a preset rule.

[0112] The following describes different preset rules.

[0113] Preset rule one: the second resource does not overlap with the muted resource.

[0114] The second resource is a part of the first resource used for transmitting the first information; and the part of the resource does not overlap with the mute resource.

[0115] The terminal excludes the mute resource in the first resource when determining the second resource used for transmitting the first information. That is, the second resource does not include the mute resource in the first resource; that is, the second resource includes the resource in the first resource that does not overlap with the mute resource.

[0116] That is, for the mute resource, the mute resource is not used for mapping or transmitting the first information; or, the mute resource is not available for transmitting the first information; or, the mute resource is unavailable resource of the first information.

[0117] In some embodiments, the mute resource is enabled after the first signaling configuration; in other embodiments, the mute resource is enabled or disabled by other signaling after the first signaling configuration.

[0118] In some embodiments, the second resource includes at least one RE in the first resource except the RE occupied by the mute resource. That is, when determining the second resource in the first resource, the RE occupied by the mute resource is excluded. As shown in FIG. 7(a), taking the first DMRS in the PUSCH occupying the third symbol and the first information occupying four REs as an example, in the case that the mute resource is configured on the fourth symbol, four REs that do not overlap with the mute resource are selected as the second resource for transmitting the first information; as shown in the figure, four REs on the fourth symbol that do not overlap with the mute resource are selected to transmit the first information.

[0119] By avoiding the mute resource in the manner of transmitting the first information, that is, excluding the mute resource when determining the second resource for transmitting the first information, the erroneous transmission or omitted transmission of the first information caused by the enabled mute resource can be avoided, and the transmission efficiency of the first information is improved.

[0120] In other embodiments, the second resource does not include the resource in the first resource occupying the same time domain symbol as the mute resource; or, the second resource includes at least one RE in the first resource that does not overlap in time domain with the mute resource; or, the second resource includes at least one RE in the first resource except the resource on the symbol occupied by the mute resource. That is, when determining the second resource in the first resource, all REs on the symbol where the mute resource is located are excluded. As shown in FIG. 7(b), taking the first DMRS in the PUSCH occupying the third symbol and the first information occupying four REs as an example, in the case that the mute resource is configured on the fourth symbol, four REs that are not on the fourth symbol are selected as the second resource for transmitting the first information; as shown in the figure, four REs on the fifth symbol are selected to transmit the first information.

[0121] Since the mute resource is used to measure the reference signal of other base stations, it also affects the transmission of the first information on the time domain resource where the mute resource is located. Therefore, by excluding all resources in the symbol where the mute resource is located when determining the second resource for transmitting the first information, the influence of the mute resource on the transmission of the first information when measuring is avoided, and the transmission efficiency of the first information is further improved.

[0122] Taking the first information as HARQ-ACK as an example, the possible implementation manner of the mapping rule of the first information is illustrated by using the preset rule one. The HARQ-ACK is mapped from the first symbol after the DMRS, and the specific mapping rule is related to the number of REs occupied. The number of symbols after the HARQ-ACK modulation, that is, the number of REs occupied, is as follows according to the formula defined in TS 38212 6.3.2.4.1.1:

[0123] wherein, is the number of REs available for transmitting uplink control information (UCI) in the lth orthogonal frequency-division multiplexing (OFDM) symbol.

[0124] In the related art, in the case where the lth OFDM symbol is used for transmitting DMRS, that is, all REs in the symbol occupied by the DMRS cannot be used for UCI transmission; in the case where the lth OFDM symbol is not used for transmitting DMRS, wherein, is the number of REs for transmitting PTRS in the lth OFDM symbol, is the number of REs on one OFDM, that is, the REs occupied by the PTRS cannot be used for UCI transmission.

[0125] In the preset rule one, the mute resource also cannot be used for the transmission of the first data (in this example, taking the HARQ-ACK in the UCI as an example), and at this time the number of available REs can be specified as one of the following manners:

[0126] Implementation manner one: in the case where the mute resource occupies REs in the lth OFDM symbol, then that is, after REs in the symbol are occupied by the mute resource, there are still The fourth RE can be used for UCI (HARQ-ACK) transmission. As shown in FIG. 7(a), the fourth symbol has remaining REs that can be used for transmitting the first information.

[0127] Embodiment two: if the lth OFDM symbol has a silent resource, then That is, if the resource used for transmitting the first information does not include the resource whose time domain symbol is occupied by the silent resource and the time domain symbol occupied by the first resource, the number of REs on the time domain symbol occupied by the silent resource that can be used for UCI (HARQ-ACK) transmission is 0. As shown in FIG. 7(b), all REs on the fourth symbol are not used for transmitting the first information.

[0128] Pre-set rule two: if the silent resource overlaps with the third resource in the first resource, the silent resource is disabled.

[0129] That is, if the silent resource conflicts with the resource used for transmitting the first information, based on the pre-set rule two, the silent resource is disabled, and the terminal transmits the first information on the third resource. The third resource is the resource in the first resource used for transmitting the first information. The third resource is a resource pre-configured for transmitting the first information, or the third resource is a resource agreed by a protocol for transmitting the first information.

[0130] That is, if the silent resource conflicts with the third resource used for transmitting the first information, based on the pre-set rule two, the silent resource avoids the third resource. The silent resource is disabled, that is, the silent resource is not used for channel estimation, thereby ensuring the complete and correct transmission of the first information.

[0131] In some embodiments, the part of the silent resource overlapping with the third resource is disabled; in other embodiments, the silent resource is not enabled.

[0132] Pre-set rule three: if the silent resource overlaps with the third resource in the first resource, the silent resource is enabled and the resource in the third resource overlapping with the silent resource is not used for transmitting the first information.

[0133] That is, if the silent resource conflicts with the resource used for transmitting the first information, based on the pre-set rule three, the silent resource is not used for transmitting the first information, that is, the part of the third resource overlapping with the silent resource is not used for transmitting the first information. The third resource is the resource in the first resource used for transmitting the first information. Optionally, the third resource is a resource pre-configured for transmitting the first information, or the third resource is a resource agreed by a protocol for transmitting the first information.

[0134] That is, in the case that the third resource for transmitting the first information conflicts with the mute resource, the third resource avoids the mute resource based on the preset rule three. The mute resource is enabled to correctly estimate the channel and improve the efficiency of channel transmission.

[0135] In some embodiments, the mute resource is enabled after the first signaling configuration; in other embodiments, the mute resource is enabled by other signaling after the first signaling configuration.

[0136] In some embodiments, in the case that the mute resource overlaps with the third resource in the first resource, the first information is transmitted on at least one RE in the third resource which does not overlap with the mute resource. As shown in FIG. 8(a), taking the first DMRS in the PUSCH occupying the third symbol and the first information occupying four REs as an example. The mute resource configured on the fourth symbol conflicts with the third resource for transmitting the first information, that is, the overlapping REs of the third resource and the mute resource are represented by the diagonal hatched squares and the crossed squares in the figure; as shown in the figure, there are four REs for transmitting the first information on the fourth symbol, of which two REs overlap with the mute resource, and the first information is transmitted on the other two REs which do not overlap with the mute resource.

[0137] In other embodiments, in the case that the mute resource overlaps with the third resource in the first resource, the first information is transmitted on at least one RE on the symbol in the first resource except the symbol where the mute resource is located. As shown in FIG. 8(b), taking the first DMRS in the PUSCH occupying the third symbol and the first information occupying four REs as an example. The mute resource is configured on the fourth symbol, and if the first information is transmitted on the fourth symbol, it may conflict with the mute resource; in order to ensure the correct and complete transmission of the first information, the first information is mapped to the fifth symbol for transmission as shown in the figure.

[0138] The terminal determines the resource for transmitting the first information by adopting the preset rule two or the preset rule three, so that the mute information on the mute resource and the first information avoid each other, avoiding the influence of the enablement of the mute resource on the mapping or transmission of the first information.

[0139] It should be noted that the preset rule two and the preset rule three are optional solutions when the mute resource and the third resource for transmitting the first information conflict; selecting the preset rule two or the preset rule three can be agreed by the protocol, or the priority information can be indicated by signaling to determine the preset rule. That is, in the case that the mute resource overlaps with the third resource, the resource for transmitting the first information and the enablement of the mute resource are determined according to the priority information; wherein the third resource is the resource in the first resource for transmitting the first information.

[0140] In some embodiments, the mute resource is disabled in the case that the mute resource overlaps with the third resource and the priority information indicates that the priority of the mute resource is lower than the priority of the third resource; in other embodiments, the mute resource is enabled and the resource of the third resource overlapping with the mute resource is not used for transmitting the first information in the case that the mute resource overlaps with the third resource and the priority information indicates that the priority of the mute resource is higher than the priority of the third resource.

[0141] That is, in the case that the priority of the mute resource is lower than the priority of the third resource, preset rule two is adopted; in the case that the priority of the mute resource is higher than the priority of the third resource, preset rule three is adopted.

[0142] In summary, the technical scheme provided by the embodiments of the present application guarantees the transmission of the first information in the first uplink channel, avoids or solves the conflict between the mute resource and the resource for transmitting the first information, and improves the efficiency and reliability of uplink information transmission in the case that the first resource for transmitting the first uplink channel and the mute resource overlap.

[0143] In addition, the mute resource can be used for channel estimation, such as measurement of CLI, in the case that the mute resource is enabled, so that the problem of weakening of uplink coverage caused by CLI between base stations can be effectively improved in the receiver of the enhanced base station, and the efficiency of the SBFD technology is improved.

[0144] In addition, the terminal determines the resource for transmitting the first information by adopting preset rule one, avoids the erroneous transmission or missed transmission of the first information caused by the enablement of the mute resource by means of avoiding the mute resource through the transmission of the first information, i.e., excluding the mute resource when determining the second resource for transmitting the first information, and improves the integrity and transmission efficiency of the first information.

[0145] In addition, in preset rule one, all resources in the symbol occupied by the mute resource are excluded when determining the second resource for transmitting the first information, which avoids the influence of the mute resource on the transmission of the first information on the time-domain resource where the mute resource is located when the mute resource is measured, and further improves the transmission efficiency of the first information.

[0146] In addition, the terminal determines the resource for transmitting the first information by adopting preset rule two or preset rule three, so that the mute information on the mute resource and the first information avoid each other, and the influence of the enablement of the mute resource on the mapping or transmission of the first information is avoided.

[0147] In addition, the terminal can determine the priority order between the mute resource and the third resource for transmitting the first information by receiving signaling containing priority information when determining the resource for transmitting the first information according to the preset rule two or the preset rule three, flexibly adjust the adopted preset rule according to the actual situation, and further improve the transmission efficiency of the first information and the use efficiency of the mute resource.

[0148] FIG. 9 shows an embodiment of a flowchart of a resource determination method provided by an embodiment of the present application, which can be applied to the communication system shown in FIG. 4 and is executed by the terminal 20 in FIG. 4. The method can include the following steps:

[0149] Step 420: The terminal does not expect the resource associated with the first information to completely overlap with the mute resource.

[0150] The first information is uplink information transmitted by the terminal to the network device. In some embodiments, the first information includes HARQ-ACK information; in other embodiments, the first information includes CSI, such as CSI part 1 and CSI part 2; in other embodiments, the first information is data, such as data transmitted on PUSCH.

[0151] The resource associated with the first information is a resource configured for transmitting the first information; or, the resource associated with the first information is a resource actually used for transmitting the first information; or, the resource associated with the first information is a resource that can be configured for transmitting the first information; or, the resource associated with the first information is a resource capable of transmitting the first information, etc. The resource associated with the first information includes various resources related to the transmission of the first information, which is not limited in the present application.

[0152] In some embodiments, the resource associated with the first information does not include at least one of a resource occupied by a symbol where a DMRS is located and a resource occupied by a PTRS. For example, in the case where the PTRS is transmitted in the first uplink channel, all REs in the symbol where the DMRS is located and the REs occupied by the PTRS are not used for mapping and transmission of the first information; in the case where the PTRS is not transmitted in the first uplink channel, all REs in the symbol where the DMRS is located are not used for mapping and transmission of the first information.

[0153] The mute resource is a resource for channel estimation, such as measuring CLI interference, inter-base station interference, adjacent channel interference, etc. In order to accurately perform channel estimation, the mute resource should avoid conflict with the resource for transmitting the first information, and the mute resource needs to be configured around the DMRS.

[0154] In some embodiments, the muted resource is enabled by signaling; or, the muted resource is enabled after being configured. That is, the muted resource is enabled by signaling after being configured; or, the muted resource is enabled by default after being configured.

[0155] In some embodiments, the terminal does not expect the third resource to overlap with the muted resource. The third resource is a resource used for transmitting the first information. Optionally, the third resource is a resource pre-configured for transmitting the first information, or, the third resource is a resource agreed by protocol for transmitting the first information, or, the third resource is a resource actually used for transmitting the first information.

[0156] That is, the terminal does not expect the third resource to overlap with the muted resource, and the terminal does not need to consider the muted resource when transmitting the first information on the third resource. For example, the muted resource and the third resource do not appear in a same PUSCH; for another example, the muted resource and the third resource are in different time domain positions in a same PUSCH and do not overlap, such as the muted resource is located on at least one symbol before the first DMRS, and the third resource is located on at least one symbol after the first DMRS, and the like.

[0157] In other embodiments, the terminal does not expect the muted resource to overlap with A symbols after the first DMRS in the first uplink channel; wherein the A symbols include the third resource, or, the A symbols partially overlap with the third resource in time domain, and A is a natural number. The third resource is a resource used for transmitting the first information; the third resource is a resource pre-configured for transmitting the first information, or, the third resource is a resource agreed by protocol for transmitting the first information.

[0158] That is, the terminal expects the muted resource to not overlap with the resource on the A symbols after the first DMRS in the first uplink channel; or, the terminal expects the muted resource to not include the resource on the A symbols after the first DMRS in the first uplink channel; or, the terminal expects the muted resource to include the resource on symbols other than the A symbols after the first DMRS in the first uplink channel.

[0159] In some embodiments, in the case that the third resource is included on the A symbols, the third resource does not overlap with the muted resource, and the terminal transmits the first information to the network device through the first uplink channel on the third resource.

[0160] In other embodiments, in the case that the A symbols partially overlap with the third resource in time domain, the third resource can partially overlap with the muted resource, or can not overlap with the muted resource; but the part of the third resource overlapping with the A symbols does not overlap with the muted resource; that is, the third resource includes the part not overlapping with the muted resource, and can be used for transmitting the first information.

[0161] That is, in the case that the mute resource partially overlaps with the third resource, the first information is transmitted in the part of the third resource that does not overlap with the mute resource; that is, the part of the third resource that overlaps with the mute resource is not used for transmission of the first information.

[0162] In some embodiments, in the case that the mute resource partially overlaps with the third resource, the terminal excludes the part of the resource that overlaps with the mute resource when determining the resource for transmitting the first information in the third resource, and then maps and transmits the first information in the remaining resource, so as to guarantee complete transmission of the first information.

[0163] In some other embodiments, in the case that the mute resource partially overlaps with the third resource, the terminal maps the first information first, and then transmits the first information on the part of the third resource that does not overlap with the mute resource; that is, if the first information is mapped to the RE where the mute resource is located, the RE is not used for transmission of the first information. Since the first information usually includes repeated redundant information, the mapping first and then excluding manner has little impact on transmission of the first information; this manner avoids changing the mapping rule and is simpler.

[0164] In some other embodiments, for the transmission manner of mapping the first information first and then transmitting the first information on the part of the third resource that does not overlap with the mute resource, in the process of configuring the third resource by using the third signaling, the network device configures a higher bias value index to the terminal device to guarantee redundant transmission of the first information, and the bias value indicated by the bias value index is used to determine the configuration parameter of the third resource. For example, if the transmission manner of mapping the first information first and then transmitting the first information on the part of the third resource that does not overlap with the mute resource is the first transmission manner, the third signaling carries a first bias value index, and the first bias value indicated by the first bias value index is greater than a second bias value. The first bias value is used to determine the resource quantity of the third resource in the first transmission manner, and the second bias value is used to determine the resource quantity of the third resource in a non-first transmission manner. Optionally, the first bias value is determined based on the resource quantity of the mute resource and the third resource that overlaps. The more the resource quantity of the mute resource and the third resource that overlaps, the greater the first bias value, and the two are in a positive correlation.

[0165] Optionally, the bias value can be a bias value "BetaOffset". The bias value "BetaOffset" is used to define the resource quantity required for a user equipment (UE) to transmit the first information (such as multiplexed HARQ-ACK information and CSI reporting) on the PUSCH. Part of the correspondence between the bias value index and the bias value can be exemplarily referred to Table 1.

[0166] Table 1

[0167] It should be noted that the above table is only illustrative, and in different embodiments, all or part of the rows in the table can form a new table with any other possible row, and the present embodiment does not limit this.

[0168] In order to realize that the terminal does not expect the resource associated with the first information to completely overlap with the mute resource, the configuration of the mute resource includes at least one of the following:

[0169] The mute resource is located on at least one symbol before the first time domain reference point; since the first information is usually configured from one symbol after the symbol where the first DMRS is located, by configuring the mute resource on the symbol before the symbol where the first DMRS is located, the overlap between the mute resource and the resource for transmitting the first information is avoided.

[0170] The mute resource is configured to start from at least a second symbol after the first time domain reference point; by configuring the mute resource to start from at least a second symbol after the symbol where the first DMRS is located, at least one symbol after the symbol where the first DMRS is located is used for transmitting the first information, thereby avoiding the complete overlap between the mute resource and the resource for transmitting the first information.

[0171] The mute resource is configured to start after the second time domain reference point; by configuring the mute resource after the symbol where the mapping of the first information ends, the overlap between the mute resource and the resource for transmitting the first information is avoided.

[0172] The mute resource is configured based on the first time domain reference point or the third time domain reference point, and in the case where there is mapping of the first information on the symbol where the mute resource is configured, the mute resource is configured with a delay of one symbol; that is, the mute resource is configured around the symbol where the first DMRS is located or starts after the first symbol of the first uplink channel, and in the case where there is mapping of the first information on the symbol where the mute resource is configured, the mute resource is configured with a delay of one symbol, and by avoiding the resource for transmitting the first information by the mute resource, the overlap between the mute resource and the resource for transmitting the first information is avoided.

[0173] Wherein, the first time domain reference point is the symbol where the first DMRS is located, the second time domain reference point is the last symbol of the mapping of the first information, and the third time domain reference point is the first symbol of the first uplink channel.

[0174] In some embodiments, the relative position between the configuration position of the mute resource and the aforementioned time domain reference point is indicated by bias information. The bias information is indicated by signaling or agreed by protocol.

[0175] As shown in FIG. 10, two possible ways of configuring the mute resource are shown, taking the value of A as 1 as an example. In FIG. 10(a), the mute resource is configured on the 1st and 3rd symbols after the second time domain reference point, i.e., the 1st and 3rd symbols after the end of the first information mapping (i.e., symbol 5 and symbol 7 in the figure); by configuring the mute resource on the symbol after the end of the first information mapping, the transmission resource of the first information is avoided from conflicting with the mute resource.

[0176] In FIG. 10(b), the mute resource is configured based on the first time domain reference point, as shown, the mute resource is configured on one symbol before and after the first DMRS (i.e., symbol 2 and symbol 4 in the figure); since there is transmission of the first information on symbol 4, the mute resource on symbol 4 is delayed by one symbol, i.e., delayed to symbol 5.

[0177] It should be noted that the two ways of configuring the mute resource shown in FIG. 10 both require the terminal and the network device to have consistent understanding of the bit length of the first information transmitted by the terminal on the first uplink channel.

[0178] In some embodiments, the terminal receives first signaling for indicating the time domain configuration and / or the frequency domain configuration of the mute resource, and the first signaling is high layer signaling or downlink control signaling.

[0179] In another embodiment, the terminal receives third signaling sent by the network device, and the third signaling is used for configuring a third resource, which is a resource configured for transmitting the first information.

[0180] It should be noted that in the technical solution provided in the embodiment, the terminal does not expect the resource associated with the first information to completely overlap with the mute resource, however, the network device may or may not meet the expectation of the terminal. That is, the network device will try to meet the expectation of the terminal as much as possible, but according to the actual situation, the network device can also independently configure the mute resource and the like.

[0181] In summary, by not expecting the resource associated with the first information to completely overlap with the mute resource, the terminal avoids complete conflict between the resource for transmitting the first information and the mute resource, so that the first information can be transmitted on the resource that does not overlap with the mute resource, and the efficiency and reliability of the uplink information transmission are improved.

[0182] In addition, the mute resource in the method can be used for channel estimation, such as CLI measurement, so that the problem of weakening of uplink coverage caused by CLI between base stations in the receiver of the enhanced base station can be effectively improved, and the efficiency of the SBFD technology is improved.

[0183] Please refer to FIG. 11, which shows a flow chart of a method for receiving uplink information according to an embodiment of the present application. The method can be applied to the communication system shown in FIG. 4 and is executed by the network device 10 in FIG. 4. The method can include the following steps:

[0184] Step 520: receiving the first information through the first uplink channel in the part of the first resource.

[0185] The first uplink channel is an uplink channel through which the terminal transmits information or data to the network device. For example, the first uplink channel is a PUSCH or a PUCCH.

[0186] The first resource is a resource used for transmitting the first uplink channel; and the part of the resource is determined based on a preset rule when the first resource and the mute resource overlap.

[0187] For example, when the first resource and the mute resource overlap, the part of the first resource is determined based on a preset rule for mapping and transmitting the first information. That is, when the first resource and the mute resource conflict, the terminal transmits the first information through the first uplink channel in the part of the first resource based on a preset rule.

[0188] In some embodiments, the part of the first resource for transmitting the first information does not include at least one of a resource occupied by a symbol where a DMRS is located and a resource occupied by a PTRS. For example, when the PTRS is transmitted in the first uplink channel, all REs in the symbol where the DMRS is located and the REs occupied by the PTRS are not used for mapping and transmitting the first information; when the PTRS is not transmitted in the first uplink channel, all REs in the symbol where the DMRS is located are not used for mapping and transmitting the first information.

[0189] The first information is uplink information sent by the terminal to the network device. In some embodiments, the first information includes HARQ-ACK information; in other embodiments, the first information includes CSI, such as CSI part 1 and CSI part 2; and in other embodiments, the first information is data, such as data transmitted on a PUSCH.

[0190] The mute resource is a resource used for channel estimation, such as measuring CLI interference. In order to accurately perform channel estimation, the mute resource should avoid conflict with the resource for transmitting the first information, and the mute resource should be configured around the DMRS.

[0191] In some embodiments, the mute resource is enabled by signaling; or, the mute resource is enabled after being configured. That is, the mute resource is controlled by signaling after being configured; or, the mute resource is in an enabled state by default after being configured.

[0192] In a case where the first resource and the silence resource exist overlap, i.e., a case where the resource for mapping and transmitting the first information and the silence resource can exist conflict, it is needed to determine the resource for transmitting the first information in the first resource based on a preset rule and transmit; i.e., in a case where the first resource and the silence resource exist overlap, based on the preset rule, the terminal transmits the first information in part of the resource in the first resource through the first uplink channel, and the network equipment receives the first information in part of the resource in the first resource through the first uplink channel.

[0193] The preset rule includes at least one of the following:

[0194] The preset rule one: the second resource and the silence resource do not exist overlap.

[0195] The part of the resource is the second resource, i.e., the second resource is the resource actually used for transmitting the first information. The preset rule includes: the second resource and the silence resource do not exist overlap. I.e., the resource for transmitting the first information is determined in the part of the first resource which does not overlap with the silence resource.

[0196] That is, the silence resource is not used for mapping or transmitting the first information; or, the silence resource is not available for transmitting the first information; or, the silence resource is the unavailable resource of the first information.

[0197] In some embodiments, the second resource includes at least one RE in the first resource except the RE occupied by the silence resource.

[0198] In another embodiment, the second resource does not include the resource in the first resource which occupies the same time domain symbol as the silence resource; or, the second resource includes at least one RE in the first resource which does not overlap in time domain with the silence resource; or, the second resource includes at least one RE in the first resource except the resource on the time domain symbol occupied by the silence resource. That is, when the second resource is determined in the first resource, all REs on the symbol where the silence resource is located are excluded.

[0199] The preset rule two: in a case where the silence resource and the third resource in the first resource exist overlap, the silence resource is not enabled.

[0200] That is, in a case where the silence resource and the resource for transmitting the first information exist conflict, based on the preset rule two, the silence resource is not enabled, and the terminal transmits the first information on the third resource. Wherein, the third resource is the resource in the first resource for transmitting the first information; the third resource is the resource pre-configured for transmitting the first information, or the third resource is the resource agreed by the protocol for transmitting the first information.

[0201] That is, in the case that the muting resource and the third resource for transmitting the first information collide, the third resource avoids the muting resource based on the preset rule two. The muting resource is not enabled, i.e., the muting resource is not used for channel estimation, so as to guarantee the complete and correct transmission of the first information.

[0202] In some embodiments, the part of the muting resource overlapping with the third resource is not enabled; in other embodiments, the muting resource is not enabled.

[0203] The preset rule three: in the case that the muting resource overlaps with the third resource in the first resource, the muting resource is enabled and the resource in the third resource overlapping with the muting resource is not used for transmitting the first information.

[0204] That is, in the case that the muting resource and the resource for transmitting the first information collide, the muting resource is not used for transmitting the first information based on the preset rule three, i.e., the part of the third resource overlapping with the muting resource is not used for transmitting the first information. The third resource is the resource in the first resource for transmitting the first information. Optionally, the third resource is the resource pre-configured for transmitting the first information, or the third resource is the resource agreed by the protocol for transmitting the first information.

[0205] That is, in the case that the muting resource and the third resource for transmitting the first information collide, the third resource avoids the muting resource based on the preset rule three. The muting resource is enabled to correctly estimate the channel, so as to improve the efficiency of channel transmission.

[0206] In some embodiments, the muting resource is enabled after the first signaling configuration; in other embodiments, the muting resource is enabled by other signaling after the first signaling configuration.

[0207] In some embodiments, in the case that the muting resource overlaps with the third resource in the first resource, the first information is transmitted on at least one RE in the third resource which does not overlap with the muting resource.

[0208] In other embodiments, in the case that the muting resource overlaps with the third resource in the first resource, the first information is transmitted on at least one RE in the symbol of the first resource except the symbol where the muting resource is located.

[0209] It should be noted that the preset rule two and the preset rule three are optional solutions when the mute resource and the third resource for transmitting the first information conflict; selecting the preset rule two or the preset rule three can be agreed by a protocol, or a priority information can be indicated by signaling, and the preset rule is determined according to the priority information. That is, in the case that the mute resource and the third resource overlap, the resource for transmitting the first information and the enabling condition of the mute resource are determined according to the priority information; the third resource is the resource in the first resource for transmitting the first information; the priority information is agreed by a protocol, or the priority information is indicated by signaling.

[0210] In some embodiments, in the case that the mute resource and the third resource overlap and the priority information indicates that the priority of the mute resource is lower than the priority of the third resource, the mute resource is not enabled; in other embodiments, in the case that the mute resource and the third resource overlap and the priority information indicates that the priority of the mute resource is higher than the priority of the third resource, the mute resource is enabled and the resource in the third resource overlapping with the mute resource is not used for transmitting the first information.

[0211] That is, in the case that the priority of the mute resource is lower than the priority of the third resource, the preset rule two is adopted; in the case that the priority of the mute resource is higher than the priority of the third resource, the preset rule three is adopted.

[0212] In some embodiments, before step 520, the network device sends a first signaling to the terminal, the first signaling being used for indicating the time domain configuration and / or the frequency domain configuration of the mute resource, and the first signaling being a high layer signaling or a downlink control signaling.

[0213] In other embodiments, the network device sends a second signaling to the terminal, the second signaling being used for configuring the first resource, and the first resource being the resource used for transmitting the first uplink channel.

[0214] In other embodiments, the network device sends a third signaling to the terminal, the third signaling being used for configuring the third resource, and the third resource being the resource configured to be used for transmitting the first information.

[0215] In other embodiments, the network device sends a fourth signaling to the terminal, the fourth signaling being used for indicating the priority information, and the priority information being used for indicating the priority relationship between the mute resource and the resource for transmitting the first information.

[0216] In summary, the technical scheme provided by the embodiments of the present application guarantees the transmission of the first information in the first uplink channel, avoids the conflict between the mute resource and the resource for transmitting the first information, and improves the efficiency and reliability of the uplink information transmission.

[0217] In addition, the mute resource in the method can be used for channel estimation, such as measurement of CLI, in an enabled case, so that the problem of weakening of uplink coverage caused by CLI between base stations can be effectively improved in the receiver of the enhanced base station, and the efficiency of the SBFD technology is improved.

[0218] FIG. 12 shows a structural block diagram of a terminal device according to an embodiment of the present application. The terminal device has a function of implementing the method examples of the terminal described above, which can be implemented by hardware or by execution of corresponding software by hardware. As shown in FIG. 12, the terminal device can include a sending module 640, which can be implemented by a transmitter in the communication device shown in FIG. 15.

[0219] In a possible implementation, the sending module 640 is configured to, in a case where the first resource and the mute resource overlap, transmit the first information through the first uplink channel in part of the first resource based on a preset rule.

[0220] The first uplink channel is an uplink channel through which the sending module 640 transmits information or data to the network device. For example, the first uplink channel is a PUSCH or a PUCCH.

[0221] The first resource is a resource used for transmission of the first uplink channel.

[0222] For example, in a case where the first resource and the mute resource overlap, part of the first resource is determined based on a preset rule to be used for mapping and transmission of the first information; that is, in a case where the first resource and the mute resource conflict, the first information is transmitted through the first uplink channel in part of the first resource based on a preset rule.

[0223] In some embodiments, the part of the first resource used for transmission of the first information does not include at least one of a resource occupied by a symbol where a DMRS is located and a resource occupied by a PTRS. For example, in a case where the PTRS is transmitted in the first uplink channel, all REs on the symbol where the DMRS is located and the REs occupied by the PTRS are not used for mapping and transmission of the first information; in a case where the PTRS is not transmitted in the first uplink channel, all REs on the symbol where the DMRS is located are not used for mapping and transmission of the first information.

[0224] The first information is uplink information sent by the sending module 640 to the network device. In some embodiments, the first information includes HARQ-ACK information; in other embodiments, the first information includes CSI, such as CSI part 1 and CSI part 2; in other embodiments, the first information is data, such as data transmitted on a PUSCH.

[0225] The muted resource is a resource for channel estimation, such as measuring CLI interference; in order to accurately perform channel estimation, the muted resource should avoid conflict with the resource for transmitting the first information, and the muted resource needs to be configured around the DMRS.

[0226] In some embodiments, the muted resource is enabled by signaling; or, the muted resource is enabled after being configured. That is, the muted resource is controlled by signaling to enable it after being configured; or, the muted resource is in an enabled state by default after being configured.

[0227] In some embodiments, the enabled muted resource is not used for mapping or transmitting the first information; or, the enabled muted resource is not available for transmitting the first information; or, the enabled muted resource is unavailable resource for the first information. That is, the first information is mapped and transmitted on the resource in the first resource except the enabled muted resource. That is, the first information is not transmitted on the enabled muted resource; that is, the resource for transmitting the first information is not the enabled muted resource.

[0228] In the case where the first resource and the muted resource overlap, that is, the resource for mapping and transmitting the first information and the muted resource may conflict, the resource for transmitting the first information in the first resource needs to be determined and transmitted based on a preset rule; that is, in the case where the first resource and the muted resource overlap, the first information is transmitted through the first uplink channel in part of the resource in the first resource based on a preset rule.

[0229] The following describes different preset rules respectively.

[0230] Preset rule one: the second resource does not overlap with the muted resource.

[0231] The second resource is part of the resource in the first resource for transmitting the first information; the part of the resource does not overlap with the muted resource.

[0232] The sending module 640 excludes the muted resource in the first resource when determining the second resource for transmitting the first information. That is, the second resource does not include the muted resource in the first resource; that is, the second resource includes the resource in the first resource that does not overlap with the muted resource.

[0233] That is, for the muted resource, the muted resource is not used for mapping or transmitting the first information; or, the muted resource is not available for transmitting the first information; or, the muted resource is unavailable resource for the first information.

[0234] In some embodiments, the muted resource is enabled after being configured by the first signaling; in other embodiments, the muted resource is enabled or not enabled by other signaling after being configured by the first signaling.

[0235] In some embodiments, the second resource includes at least one RE in the first resource except for the RE occupied by the mute resource. That is, when determining the second resource in the first resource, the RE occupied by the mute resource is excluded.

[0236] By avoiding the mute resource through the transmission of the first information, that is, excluding the mute resource when determining the second resource for transmitting the first information, the erroneous transmission or missed transmission of the first information caused by the mute resource can be avoided, and the transmission efficiency of the first information is improved.

[0237] In other embodiments, the second resource does not include a resource in the first resource that occupies the same time domain symbol as the mute resource; or, the second resource includes at least one RE in the first resource that does not overlap in time domain with the mute resource; or, the second resource includes at least one RE in the first resource except for the resource on the time domain symbol occupied by the mute resource. That is, when determining the second resource in the first resource, all REs on the symbol where the mute resource is located are excluded.

[0238] Since the mute resource is used to measure the reference signal of other base stations, it will also affect the transmission of the first information on the time domain resource where the mute resource is located. Therefore, by excluding all resources on the symbol where the mute resource is located when determining the second resource for transmitting the first information, the influence of the mute resource on the transmission of the first information when measuring is avoided, and the transmission efficiency of the first information is further improved.

[0239] Pre-set rule two: in the case where the mute resource overlaps with a third resource in the first resource, the mute resource is not enabled.

[0240] That is, in the case where the mute resource conflicts with the third resource for transmitting the first information, based on the pre-set rule two, the mute resource is not enabled, and the sending module 640 transmits the first information on the third resource. The third resource is a resource in the first resource for transmitting the first information; the third resource is a resource pre-configured for the transmission of the first information, or the third resource is a resource agreed by the protocol for the transmission of the first information.

[0241] That is, in the case where the mute resource and the third resource for transmitting the first information conflict, based on the pre-set rule two, the mute resource avoids the third resource. The mute resource is not enabled, that is, the mute resource is not used for channel estimation, so as to ensure the complete and correct transmission of the first information.

[0242] In some embodiments, the part of the mute resource that overlaps with the third resource is not enabled; in other embodiments, none of the mute resources are enabled.

[0243] Pre-set rule three: in the case that the muted resource and a third resource in the first resource exist overlap, the muted resource is enabled and the resource in the third resource which overlaps with the muted resource is not used for transmitting the first information.

[0244] That is, in the case that the muted resource and the resource used for transmitting the first information exist conflict, based on the pre-set rule three, the muted resource is not used for transmitting the first information, that is, the part in the third resource which overlaps with the muted resource is not used for transmitting the first information. Wherein, the third resource is the resource in the first resource used for transmitting the first information. Optionally, the third resource is the resource pre-configured for transmitting the first information, or the third resource is the resource agreed by protocol for transmitting the first information.

[0245] That is, in the case that the muted resource and the third resource used for transmitting the first information exist conflict, based on the pre-set rule three, the third resource avoids the muted resource. The muted resource is enabled to correctly estimate the channel and improve the efficiency of channel transmission.

[0246] In some embodiments, the muted resource is enabled after the first signaling configuration; in other embodiments, the muted resource is enabled by other signaling after the first signaling configuration.

[0247] In some embodiments, in the case that the muted resource and a third resource in the first resource exist overlap, the first information is transmitted on at least one RE in the third resource which does not overlap with the muted resource.

[0248] In other embodiments, in the case that the muted resource and a third resource in the first resource exist overlap, the first information is transmitted on at least one RE on the symbol in the first resource except the symbol where the muted resource is located.

[0249] It should be noted that the pre-set rule two and the pre-set rule three are optional solutions when the muted resource and the third resource used for transmitting the first information exist conflict; selecting the pre-set rule two or the pre-set rule three can be agreed by protocol, or the priority information can be indicated by signaling, and the pre-set rule is determined according to the priority information. That is, in the case that the muted resource and the third resource exist overlap, the resource used for transmitting the first information and the enabling condition of the muted resource are determined according to the priority information; wherein, the third resource is the resource in the first resource used for transmitting the first information.

[0250] In some embodiments, in the case that the muted resource and the third resource exist overlap and the priority information indicates that the priority of the muted resource is lower than the priority of the third resource, the muted resource is not enabled; in other embodiments, in the case that the muted resource and the third resource exist overlap and the priority information indicates that the priority of the muted resource is higher than the priority of the third resource, the muted resource is enabled and the resource in the third resource which overlaps with the muted resource is not used for transmitting the first information.

[0251] That is, in the case that the priority of the muted resource is lower than the priority of the third resource, preset rule two is adopted; in the case that the priority of the muted resource is higher than the priority of the third resource, preset rule three is adopted.

[0252] In another possible implementation, the terminal device further includes a receiving module 620, configured to receive first signaling.

[0253] The first signaling is used to indicate the time domain configuration and / or the frequency domain configuration of the muted resource; after receiving the first signaling, the receiving module 620 acquires the pre-configuration information of the muted resource in the first uplink channel.

[0254] In some embodiments, the first signaling is high-layer signaling or downlink control signaling. The high-layer signaling refers to the control and management signaling information of the network layer and the layers above it, for example, the first signaling is RRC; the downlink control signaling refers to the control signaling sent by the network device to the receiving module 620, including information such as DCI.

[0255] In some embodiments, the muted resource is enabled after being configured by the first signaling; in other embodiments, the muted resource is enabled or not enabled by other signaling after being configured by the first signaling.

[0256] In other embodiments, the receiving module 620 receives second signaling sent by the network device, and the second signaling is used to configure the first resource, which is a resource used to transmit the first uplink channel.

[0257] In other embodiments, the receiving module 620 receives third signaling sent by the network device, and the third signaling is used to configure the third resource, which is a resource configured to transmit the first information.

[0258] For the transmission mode of mapping the first information first and then transmitting the first information on the part of the third resource which does not overlap with the muted resource, the third signaling received by the receiving module 620 carries a higher bias value index to ensure the redundant transmission of the first information, and the bias value indicated by the bias value index is used to determine the configuration parameter of the third resource. For example, if the transmission mode of mapping the first information first and then transmitting the first information on the part of the third resource which does not overlap with the muted resource is the first transmission mode, the third signaling carries a first bias value index, and the first bias value indicated by the first bias value index is greater than a second bias value. The first bias value is a configuration parameter used to determine the resource quantity of the third resource in the first transmission mode, and the second bias value is a configuration parameter used to determine the resource quantity of the third resource in a non-first transmission mode. Optionally, the first bias value is determined based on the resource quantity of the muted resource overlapping with the third resource. The more the resource quantity of the muted resource overlapping with the third resource, the greater the first bias value, and the two are in a positive correlation.

[0259] Optionally, the bias value can be a bias value "BetaOffset". The bias value "BetaOffset" is used to define the resource quantity required by one user equipment (UE) when transmitting the first information (such as multiplexed HARQ-ACK information and CSI reporting) on the PUSCH. Part of the correspondence between the bias value index and the bias value can be exemplarily referred to Table 1.

[0260] In some other embodiments, the receiving module 620 receives fourth signaling sent by the network device, and the fourth signaling is used to indicate priority information, and the priority information is used to indicate the priority relationship between the muted resource and the resource for transmitting the first information.

[0261] Optionally, the receiving module 620 can be implemented as a stand-alone terminal device, such as a terminal device for receiving the first signaling; the sending module 640 can be implemented as a stand-alone terminal device, such as a terminal device for sending uplink information; and the present application does not limit this.

[0262] FIG. 13 shows a structural block diagram of a terminal device provided by an embodiment of the present application. The terminal device has the functions of implementing the above-mentioned terminal method examples, which can be implemented by hardware or by executing corresponding software by hardware. As shown in FIG. 13, the terminal device can include a determining module 740, wherein the determining module 740 can be implemented by the processor in the communication device shown in FIG. 15.

[0263] In a possible implementation, the determining module 740 is configured to not expect the resource associated with the first information to completely overlap with the muted resource.

[0264] The first information is uplink information sent by the determining module 740 to the network device. In some embodiments, the first information includes HARQ-ACK information; in other embodiments, the first information includes CSI, such as CSI part 1 and CSI part 2; in other embodiments, the first information is data, such as data transmitted on a PUSCH.

[0265] The resource associated with the first information is configured for transmission of the first information; or, the resource associated with the first information is used for actual transmission of the first information.

[0266] In some embodiments, the resource associated with the first information does not include at least one of a resource occupied by a symbol where a DMRS is located and a resource occupied by a phase tracking reference signal (PTRS). That is, in the case where the PTRS is transmitted in the first uplink channel, all REs in the symbol where the DMRS is located and the REs occupied by the PTRS are not used for mapping and transmission of the first information; in the case where the PTRS is not transmitted in the first uplink channel, all REs in the symbol where the DMRS is located are not used for mapping and transmission of the first information.

[0267] The muted resource is a resource used for channel estimation, such as measuring CLI interference; in order to accurately perform channel estimation, the muted resource should avoid conflict with the resource used for transmission of the first information, and the muted resource needs to be configured around the DMRS.

[0268] In some embodiments, the muted resource is enabled by signaling; or, the muted resource is enabled after being configured. That is, the muted resource is controlled by signaling after being configured; or, the muted resource is in an enabled state by default after being configured.

[0269] In some embodiments, the determining module 740 does not expect the third resource to overlap with the muted resource. The third resource is a resource used for transmission of the first information; the third resource is a resource pre-configured for transmission of the first information, or the third resource is a resource agreed by a protocol for transmission of the first information.

[0270] That is, the determining module 740 does not expect the third resource to overlap with the muted resource, so the determining module 740 does not need to consider the muted resource when transmitting the first information on the third resource. For example, the muted resource and the third resource do not appear in one PUSCH; for another example, the muted resource and the third resource are in different time domain positions in the same PUSCH and do not overlap, such as the muted resource being located on at least one symbol before the first DMRS and the third resource being located on at least one symbol after the first DMRS, and the like.

[0271] In some embodiments, the determining module 740 expects the muted resource to not overlap with the A symbols after the first DMRS in the first uplink channel; or, the determining module 740 expects the muted resource to not include the resources in the A symbols after the first DMRS in the first uplink channel; or, the determining module 740 expects the muted resource to include the resources in the symbols other than the A symbols after the first DMRS in the first uplink channel.

[0272] In other embodiments, the determining module 740 expects the muted resource to not overlap with the A symbols after the first DMRS in the first uplink channel; or, the determining module 740 expects the muted resource to not include the resources in the A symbols after the first DMRS in the first uplink channel; or, the determining module 740 expects the muted resource to include the resources in the symbols other than the A symbols after the first DMRS in the first uplink channel.

[0273] In some embodiments, in the case that the third resource is included in the A symbols, the third resource does not overlap with the muted resource, and the determining module 740 transmits the first information to the network device through the first uplink channel on the third resource.

[0274] In other embodiments, in the case that the A symbols partially overlap with the third resource, the third resource can or can not partially overlap with the muted resource; but the part of the third resource that overlaps with the A symbols does not overlap with the muted resource; that is, the third resource includes the part that does not overlap with the muted resource and can be used for transmission of the first information.

[0275] That is, in the case that the muted resource partially overlaps with the third resource, the first information is transmitted in the part of the third resource that does not overlap with the muted resource; that is, the part of the third resource that overlaps with the muted resource is not used for transmission of the first information.

[0276] In some embodiments, in the case that the muted resource partially overlaps with the third resource, when the determining module 740 determines the resource in the third resource for transmission of the first information, the part of the resource that overlaps with the muted resource is excluded first, and then the first information is mapped and transmitted in the remaining resource, so as to guarantee complete transmission of the first information.

[0277] In some embodiments, when the muted resource partially overlaps with the third resource, the determining module 740 determines the resource for transmitting the first information in the third resource, and performs mapping of the first information first, and then performs transmission of the first information in the part of the third resource which does not overlap with the muted resource; that is, if the first information is mapped to the RE in which the muted resource is located, the RE is not used for transmission of the first information. Since the first information usually includes repeated redundant information, the mapping first and then excluding manner has little impact on the transmission of the first information; this manner avoids changes to the mapping rule and is simpler.

[0278] In order to realize that the determining module 740 does not expect the resource associated with the first information to completely overlap with the muted resource, the configuration of the muted resource includes at least one of the following:

[0279] • The muted resource is located on at least one symbol before the first time domain reference point; since the first information is usually configured to start from one symbol after the symbol in which the first DMRS is located, by configuring the muted resource on the symbol before the symbol in which the first DMRS is located, the overlap between the muted resource and the resource for transmitting the first information is avoided.

[0280] • The muted resource is configured to start from at least a second symbol after the first time domain reference point; by configuring the muted resource to start from at least a second symbol after the symbol in which the first DMRS is located, at least one symbol after the symbol in which the first DMRS is located is used for transmitting the first information, and the complete overlap between the muted resource and the resource for transmitting the first information is avoided.

[0281] • The muted resource is configured to start after the second time domain reference point; by configuring the muted resource after the symbol in which the mapping of the first information ends, the overlap between the muted resource and the resource for transmitting the first information is avoided.

[0282] • The muted resource is configured based on the first time domain reference point or the third time domain reference point, and in the case that there is mapping of the first information on the symbol in which the muted resource is configured, the muted resource is configured to delay one symbol; that is, the muted resource is configured around the symbol in which the first DMRS is located or starts after the first symbol of the first uplink channel, and in the case that there is mapping of the first information on the symbol in which the muted resource is configured, the muted resource is configured to delay one symbol, and by avoiding the resource for transmitting the first information by the muted resource, the overlap between the muted resource and the resource for transmitting the first information is avoided.

[0283] Wherein, the first time domain reference point is the symbol in which the first DMRS is located, the second time domain reference point is the last symbol of the mapping of the first information, and the third time domain reference point is the first symbol of the first uplink channel.

[0284] In some embodiments, the relative position between the configuration position of the muted resource and the aforementioned time domain reference point is indicated by bias information. The bias information is indicated by signaling or is agreed by protocol.

[0285] It should be noted that in the technical solution provided in the embodiment, the determination module 740 does not expect the resource associated with the first information to completely overlap the muted resource, however, the network device may or may not meet the expectation of the determination module 740. That is, the network device will try to meet the expectation of the determination module 740 as much as possible, but according to the actual situation, the network device can also independently configure the muted resource and the like.

[0286] In another possible implementation, the terminal device further includes a receiving module 720, configured to receive first signaling.

[0287] The first signaling is used to indicate the time domain configuration and / or the frequency domain configuration of the muted resource; and the receiving module 720 acquires pre-configuration information of the muted resource in the first uplink channel after receiving the first signaling.

[0288] In some embodiments, the first signaling is high-layer signaling or downlink control signaling. The high-layer signaling refers to the control and management signaling information of the network layer and the layers above it, for example, the first signaling is RRC; the downlink control signaling refers to the control signaling sent by the network device to the receiving module 720, including information such as DCI and the like.

[0289] In some embodiments, the muted resource is enabled after being configured by the first signaling; in other embodiments, the muted resource is enabled or disabled by other signaling after being configured by the first signaling.

[0290] In other embodiments, the receiving module 720 receives third signaling sent by the network device, and the third signaling is used to configure a third resource, which is a resource configured to be used for transmitting the first information.

[0291] Optionally, the receiving module 720 can be implemented as a stand-alone terminal device, such as a terminal device receiving the first signaling; the determination module 740 can be implemented as a stand-alone terminal device, such as a terminal device determining the resource; the present application does not limit this.

[0292] FIG. 14 shows a structural block diagram of a network device according to an embodiment of the present application. The network device has functions to implement the method examples of the network device described above, which can be implemented by hardware or by executing corresponding software by hardware. As shown in FIG. 14, the network device can include a receiving module 840, wherein the receiving module 840 can be implemented by a receiver in the communication device shown in FIG. 15.

[0293] The receiving module 840 is configured to receive first information through a first uplink channel in a part of resources of the first resources.

[0294] The first uplink channel is an uplink channel through which the terminal transmits information or data to the receiving module 840. For example, the first uplink channel is a PUSCH or a PUCCH.

[0295] The first resources are resources used for transmitting the first uplink channel; and the part of resources is determined based on a preset rule in a case where the first resources and the mute resources overlap.

[0296] For example, in a case where the first resources and the mute resources overlap, the part of resources in the first resources is determined based on a preset rule for mapping and transmission of the first information; that is, in a case where the first resources and the mute resources conflict, the terminal transmits the first information through the first uplink channel in the part of resources in the first resources based on the preset rule.

[0297] In some embodiments, the part of resources in the first resources for transmitting the first information does not include at least one of resources occupied by a symbol where a DMRS is located and resources occupied by a PTRS. That is, in a case where the PTRS is transmitted in the first uplink channel, all REs on the symbol where the DMRS is located and REs occupied by the PTRS are not used for mapping and transmission of the first information; in a case where the PTRS is not transmitted in the first uplink channel, all REs on the symbol where the DMRS is located are not used for mapping and transmission of the first information.

[0298] The first information is uplink information sent by the terminal to the receiving module 840. In some embodiments, the first information includes HARQ-ACK information; in other embodiments, the first information includes CSI, such as CSI part 1 and CSI part 2; and in other embodiments, the first information is data, such as data transmitted on a PUSCH.

[0299] The mute resources are resources used for channel estimation, such as measuring CLI interference; in order to accurately perform channel estimation, the mute resources should avoid conflict with resources for transmitting the first information, and the mute resources need to be configured around the DMRS.

[0300] In some embodiments, the mute resources are enabled by signaling; or, the mute resources are enabled after being configured. That is, the mute resources are controlled to be enabled by signaling after being configured; or, the mute resources are in an enabled state by default after being configured.

[0301] In a case where the first resource and the silence resource overlap, i.e., in a case where the resource for mapping and transmitting the first information and the silence resource can conflict, the resource for transmitting the first information in the first resource needs to be determined based on a preset rule and transmission is performed; i.e., in a case where the first resource and the silence resource overlap, based on the preset rule, the terminal transmits the first information in part of the resource in the first resource through the first uplink channel, and the receiving module 840 receives the first information in part of the resource in the first resource through the first uplink channel.

[0302] The preset rule includes at least one of the following:

[0303] The preset rule one is that the second resource does not overlap with the silence resource.

[0304] The part of the resource is the second resource, i.e., the second resource is the resource actually used for transmission of the first information. The preset rule includes that the second resource does not overlap with the silence resource. I.e., the resource for transmitting the first information is determined in the part of the first resource that does not overlap with the silence resource.

[0305] That is, the silence resource is not used for mapping or transmitting the first information; or, the silence resource cannot be used for transmitting the first information; or, the silence resource is an unusable resource of the first information.

[0306] In some embodiments, the second resource includes at least one RE in the first resource except for the RE occupied by the silence resource.

[0307] In other embodiments, the second resource does not include the resource in the first resource that occupies the same time domain symbol as the silence resource; or, the second resource includes at least one RE in the first resource that does not overlap in time domain with the silence resource; or, the second resource includes at least one RE in the first resource except for the resource on the time domain symbol occupied by the silence resource. That is, when the second resource is determined in the first resource, all REs on the symbol where the silence resource is located are excluded.

[0308] The preset rule two is that in a case where the silence resource and a third resource in the first resource overlap, the silence resource is not enabled.

[0309] That is, in a case where the silence resource and the resource for transmitting the first information conflict, based on the preset rule two, the silence resource is not enabled, and the terminal transmits the first information on the third resource. The third resource is the resource in the first resource for transmitting the first information; the third resource is a resource preconfigured for transmission of the first information, or the third resource is a resource agreed by a protocol for transmission of the first information.

[0310] That is, in the case that the muting resource and the third resource for transmitting the first information collide, the third resource avoids the muting resource based on the preset rule two. The muting resource is not enabled, i.e., the muting resource is not used for channel estimation, so as to guarantee the complete and correct transmission of the first information.

[0311] In some embodiments, the part of the muting resource overlapping with the third resource is not enabled; in other embodiments, none of the muting resource is enabled.

[0312] The preset rule three: in the case that the muting resource overlaps with the third resource in the first resource, the muting resource is enabled and the resource in the third resource overlapping with the muting resource is not used for transmitting the first information.

[0313] That is, in the case that the muting resource and the resource for transmitting the first information collide, the muting resource is not used for transmitting the first information based on the preset rule three, i.e., the part of the third resource overlapping with the muting resource is not used for transmitting the first information. The third resource is the resource in the first resource for transmitting the first information. Alternatively, the third resource is the resource pre-configured for transmitting the first information, or the third resource is the resource agreed by the protocol for transmitting the first information.

[0314] That is, in the case that the muting resource and the third resource for transmitting the first information collide, the third resource avoids the muting resource based on the preset rule three. The muting resource is enabled to correctly estimate the channel, so as to improve the efficiency of channel transmission.

[0315] In some embodiments, the muting resource is enabled after the first signaling configuration; in other embodiments, the muting resource is enabled by other signaling after the first signaling configuration.

[0316] In some embodiments, in the case that the muting resource overlaps with the third resource in the first resource, the first information is transmitted on at least one RE in the third resource which does not overlap with the muting resource.

[0317] In other embodiments, in the case that the muting resource overlaps with the third resource in the first resource, the first information is transmitted on at least one RE in the symbol of the first resource except the symbol where the muting resource is located.

[0318] It should be noted that the preset rule two and the preset rule three are optional solutions when the mute resource and the third resource for transmitting the first information conflict; selecting the preset rule two or the preset rule three can be determined by a protocol agreement, or a signaling indication priority information, and the preset rule is determined according to the priority information. That is, in the case that the mute resource and the third resource overlap, the resource for transmitting the first information and the enabling condition of the mute resource are determined according to the priority information; wherein the third resource is the resource for transmitting the first information in the first resource; the priority information is determined by a protocol agreement, or the priority information is indicated by signaling.

[0319] In some embodiments, in the case that the mute resource and the third resource overlap and the priority information indicates that the priority of the mute resource is lower than the priority of the third resource, the mute resource is not enabled; in other embodiments, in the case that the mute resource and the third resource overlap and the priority information indicates that the priority of the mute resource is higher than the priority of the third resource, the mute resource is enabled and the resource of the third resource overlapping with the mute resource is not used for transmitting the first information.

[0320] That is, in the case that the priority of the mute resource is lower than the priority of the third resource, the preset rule two is adopted; in the case that the priority of the mute resource is higher than the priority of the third resource, the preset rule three is adopted.

[0321] In other embodiments, the network device further includes a sending module 820.

[0322] The sending module 820 is configured to send first signaling to the terminal, the first signaling being used to indicate the time domain configuration and / or the frequency domain configuration of the mute resource, and the first signaling being high layer signaling or downlink control signaling.

[0323] In other embodiments, the sending module 820 sends second signaling to the terminal, the second signaling being used to configure the first resource, and the first resource being the resource for transmitting the first uplink channel.

[0324] In other embodiments, the sending module 820 sends third signaling to the terminal, the third signaling being used to configure the third resource, and the third resource being the resource configured for transmitting the first information.

[0325] For the transmission manner of mapping the first information first and then transmitting the first information on the part of the third resource which does not overlap with the mute resource, the third signaling sent by the sending module 820 carries a higher bias value index to ensure the redundant transmission of the first information, and the bias value indicated by the bias value index is used to determine the configuration parameter of the third resource. For example, if the transmission manner of mapping the first information first and then transmitting the first information on the part of the third resource which does not overlap with the mute resource is the first transmission manner, the third signaling carries a first bias value index, and the first bias value indicated by the first bias value index is greater than a second bias value. The first bias value is a configuration parameter used to determine the resource quantity of the third resource in the first transmission manner, and the second bias value is a configuration parameter used to determine the resource quantity of the third resource in a non-first transmission manner. Optionally, the first bias value is determined based on the resource quantity of the overlap between the mute resource and the third resource. The more the resource quantity of the overlap between the mute resource and the third resource, the greater the first bias value, and the two are in a positive correlation.

[0326] Optionally, the bias value can be a bias value "BetaOffset". The bias value "BetaOffset" is used to define the resource quantity required for a user equipment (UE) to transmit the first information (such as multiplexed HARQ-ACK information and CSI reporting) on the PUSCH. Part of the correspondence between the bias value index and the bias value can be exemplarily referred to Table 1.

[0327] In some other embodiments, the sending module 820 sends fourth signaling to the terminal, and the fourth signaling is used to indicate priority information, and the priority information is used to indicate the priority relationship between the mute resource and the resource for transmitting the first information.

[0328] Optionally, the sending module 820 can be implemented as a stand-alone network device, such as a network device for sending the first signaling; the receiving module 840 can be implemented as a stand-alone network device, such as a network device for receiving the uplink information; the present application does not limit this.
