[0014] To make the object, technical solution and advantages of the present application clearer, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily.

[0015] The steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions. And, although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0016] The time domain resource determination method provided by the embodiments of the present application can be applied to a wireless communication system, improving the existing configuration method for PUCCH time domain resources, configuring PUCCH time domain resources in different ways according to configuration parameters containing different information, improving the PUCCH performance in different service scenarios and terminal mobility characteristics, and solving the problem of time domain resource conflict between PUCCH and other channels through more flexible PUCCH time domain resource configuration.

[0017] In a wireless communication system, the time-domain resource configuration of PUCCH is based on the starting symbol index (startingSymbolIndex) and the number of time-domain symbols (nrofSymbols) configured in different PUCCH Formats in the PUCCH resource, and determines the time-domain resource configuration of PUCCH's DMRS according to the defined data symbol and pilot DMRS symbol arrangement rules or different DMRS configuration tables. For example, for New Radio (NR) PUCCH Format 3 / 4, in the prior art, the time-domain resource configuration of DMRS can be determined according to Table 1 below, where l = 0 corresponds to the first symbol position of PUCCH transmission.

[0018] Table 1: DMRS Positions for PUCCH Format 3 and 4

[0019]

[0020] As can be seen from Table 1 above, taking NR PUCCH Format 3 and Format 4 as examples, when the starting symbol index and the number of time-domain symbols of PUCCH are determined, except for distinguishing different time-domain resource configurations of DMRS according to frequency hopping and non-frequency hopping when PUCCH length = 4 and using 2-symbol and 4-symbol time-domain resource configurations of DMRS respectively according to whether Additional DMRS is enabled when PUCCH length = 10 - 14, the time-domain resource configuration of PUCCH DMRS is relatively fixed.

[0021] Meanwhile, in the prior art, the definition of the common PUCCH resource set is shown in Table 2 below.

[0022] Table 2: PUCCH Resource Set before Dedicated PUCCH Resource Configuration

[0023]

[0024] As shown in Table 2 above, the current time-domain resource position of the common PUCCH is at the time-domain symbol position closer to the end within the time slot.

[0025] In existing commercial scenarios, considering the requirements of avoiding conflicts with downlink signals and the flexibility of uplink scheduling, the UE typically transmits sounding reference signals (SRS) on the last 1 to 4 time-domain symbols within a time slot, resulting in conflicts between the time-domain resource positions of SRS and Common PUCCH transmitted within the same time slot. Determining the transmission priorities of PUCCH and SRS according to the existing technology may cause the user equipment (UE) side to be unable to transmit SRS in this time slot. At the same time, in existing commercial scenarios, PUCCH transmission will also encounter interference from some time-domain symbols in the same system or different systems. When the time-domain symbols affected by PUCCH are located in the middle of all time-domain symbols, it has a greater impact on the performance of PUCCH resource allocation based on time-domain continuity in the existing technology.

[0026] To solve the above problems, the embodiments of the present application provide a method for determining time-domain resources, which configures PUCCH time-domain resources in different ways according to configuration parameters containing different information, improving the performance of PUCCH in different service scenarios and terminal mobility characteristics. The method for determining time-domain resources provided by the embodiments of the present application can be implemented in a communication node. The communication node can be a communication device applied to the next-generation 6G communication system and subsequent communication systems (6G and beyond), such as communication devices such as UE, base station, relay station or satellite, or communication devices of the next-generation fixed access wireless communication system, such as access point (Access Point, AC) or terminal. The embodiments of the present application do not limit this. In some possible implementation manners, the method for determining time-domain resources can be implemented by invoking computer-readable instructions stored in a memory.

[0027] In an exemplary embodiment, Figure 1 FIG. is a flowchart of a method for determining time-domain resources provided by an embodiment of the present application. This method can be applied to a wireless communication system and configures the time-domain resources of the physical uplink channel in different ways according to configuration parameters containing different information. This method can be executed by a time-domain resource determination device, which can be implemented by software and / or hardware and integrated on a communication node. The communication node can be a UE or a base station in the wireless communication system. The embodiments of the present application do not limit this.

[0028] As Figure 1 shown, the method for determining time-domain resources provided by the embodiments of the present application specifically includes the following steps:

[0030] In this embodiment, the configuration parameter can be specifically understood as the information received by the communication node from different signaling or information, which is used to indicate the time-domain resource configuration method of the physical uplink channel in the communication node.

[0031] In a specific example, when the communication node needs to configure the time-domain resources of its own physical uplink channel, it can parse the different signaling or information received, and obtain the configuration parameters that can be used to indicate the time-domain resource configuration related to the physical uplink channel from them.

[0032] S102. Determine the time-domain resources of the physical uplink channel of the communication node according to the configuration parameter.

[0034] The time-domain resource determination method provided by the embodiments of the present application receives the configuration parameter; determines the time-domain resources of the physical uplink channel of the communication node according to the configuration parameter. By adopting the above technical solution, based on the differences in the received configuration parameters, the time-domain resources of the physical uplink channels of different communication nodes in the wireless communication system are dynamically and flexibly configured, which improves the flexibility of time-domain resource configuration, reduces time-domain resource conflicts, and improves the performance of the configured time-domain resources.

[0041] It can be understood that the configuration parameters proposed in the embodiments of the present application can be not only at the UE level, but also at the ULBWP level, PUCCH resource and / or PUSCH time-domain resource configuration level, PUCCH format level, cell level, etc., to meet the physical uplink channel time-domain resource configuration requirements of different communication nodes. The embodiments of the present application do not limit this.

[0042] In one embodiment, the configuration parameters include at least one of the following:

[0043] The first configuration parameter; wherein, the first configuration parameter is configured to indicate a parameter for a communication node to configure the time-domain resources of a physical uplink channel corresponding to a reference physical uplink channel based on the configuration of the time-domain resources of the reference physical uplink channel; wherein, the reference physical uplink channel is a pre-configured physical uplink channel in the reference communication node;

[0044] The second configuration parameter; wherein, the second configuration parameter is configured to indicate a parameter of the type of the communication node;

[0045] The third configuration parameter; wherein, the third configuration parameter is configured to indicate a parameter for a communication node to configure the time-domain resources of a physical uplink channel based on the time-domain resources already configured in the physical uplink channel;

[0046] The fourth configuration parameter; wherein, the fourth configuration parameter is configured to indicate a parameter for a communication node to configure the time-domain resources of a physical uplink channel based on the number of demodulation reference signal symbols;

[0047] The fifth configuration parameter; wherein, the fifth configuration parameter is configured to indicate a symbol-level silence configuration or a configuration set of the physical uplink channel of the communication node;

[0048] The sixth configuration parameter; wherein, the sixth configuration parameter is configured to indicate an index or identifier of a silence pattern in the fifth configuration parameter;

[0049] The seventh configuration parameter; wherein, the seventh configuration parameter is configured to indicate a parameter for a communication node to configure the time-domain resources of a physical uplink channel based on the time-domain resource parameters of other physical uplink channels except the physical uplink channel of the communication node.

[0050] In this embodiment, the reference communication node can be specifically understood as a communication node that has completed the time-domain resource configuration in PUSCH or PUCCH. The reference physical uplink channel can be specifically understood as a physical uplink channel in the reference communication node that has completed the time-domain resource configuration, and this physical uplink channel can be PUSCH or PUCCH. The embodiments of the present application do not limit this.

[0051] In this embodiment, the physical uplink channel corresponding to the reference physical uplink channel can be specifically understood as another physical uplink channel of a different type from the reference physical uplink channel type. That is, assuming the reference physical uplink channel is PUSCH, the physical uplink channel corresponding to the reference physical uplink channel is PUCCH; assuming the reference physical uplink channel is PUCCH, the physical uplink channel corresponding to the reference physical uplink channel is PUSCH.

[0052] In this embodiment, the type of the communication node can be specifically understood as the type used to indicate whether the communication node is a reference communication node or a non-reference communication node.

[0053] In some examples, the symbol-level silence configuration or configuration set may include a silence switch, a silence pattern, and whether silence supports dynamic triggering, etc., which are not limited in the embodiments of the present application.

[0054] In one embodiment, determining the time-domain resources of the physical uplink channel of a communication node according to configuration parameters includes at least one of the following:

[0055] Determining the time-domain resources of the physical uplink channel of the communication node according to the first configuration parameter and the second configuration parameter;

[0056] Determining the time-domain resources of the physical uplink channel of the communication node according to the third configuration parameter;

[0057] Determining the time-domain resources of the physical uplink channel of the communication node according to the fourth configuration parameter;

[0058] Determining the time-domain resources of the physical uplink channel of the communication node according to the fifth configuration parameter and the sixth configuration parameter;

[0059] Determining the time-domain resources of the physical uplink channel of the communication node according to the seventh configuration parameter.

[0060] In one embodiment, determining the time-domain resources of the physical uplink channel of a communication node according to the first configuration parameter and the second configuration parameter includes:

[0061] Determining the communication node type of the communication node according to the second configuration parameter;

[0062] Determining the time-domain resources of the physical uplink channel of the communication node according to the communication node type and the first configuration parameter.

[0063] In a specific example, it is determined whether a communication node is a reference communication node according to a second configuration parameter, and then, based on the first configuration parameter and the configuration of time-domain resources in a reference physical uplink channel in the reference communication node, the time-domain resources of a physical uplink channel corresponding to the reference physical uplink channel type in the communication node are configured. That is, when the communication node is a reference communication node, the physical uplink channel corresponding to the reference physical uplink channel type in the communication node is configured based on the configuration of time-domain resources in the reference physical uplink channel; when the communication node is a non-reference communication node, the time-domain resources of the physical uplink channel corresponding to the reference physical uplink channel type in the communication node are configured according to the configuration of time-domain resources of the reference physical uplink channel in the reference communication node.

[0064] In some examples, it can be determined whether a communication node is a reference communication node according to whether a second configuration parameter is received, or it can also be determined whether a communication node is a reference communication node according to the parameter value corresponding to the received second configuration parameter.

[0065] In one embodiment, determining the time-domain resources of the physical uplink channel of a communication node according to the communication node type and the first configuration parameter includes at least one of the following:

[0066] When the communication node type is a reference communication node, allocate a first number of resource blocks to the physical uplink channel corresponding to the reference physical uplink channel according to the indication of the first configuration parameter; wherein, the positions of each resource block in the first number of resource blocks for transmitting demodulation reference signal symbols are the same as the positions of each resource block in the second number of resource blocks in the reference physical uplink channel for transmitting demodulation reference signal symbols;

[0067] When the communication node type is a reference communication node and the first configuration parameter meets a predefined condition, allocate a first number of resource blocks to the physical uplink channel corresponding to the reference physical uplink channel; wherein, the positions of each resource block in the first number of resource blocks for transmitting demodulation reference signal symbols are the same as the positions of each resource block in the second number of resource blocks in the reference physical uplink channel for transmitting demodulation reference signal symbols;

[0068] When the communication node type is a non-reference communication node, allocate a first number of resource blocks to the physical uplink channel corresponding to the reference physical uplink channel according to the indication of the first configuration parameter; wherein, the time-domain symbol lengths and the positions of each resource block for transmitting demodulation reference signal symbols in the first number of resource blocks are the same as those of each resource block in the second number of resource blocks in the reference physical uplink channel; wherein, the number of non-reference communication nodes is one or more;

[0069] When the communication node type is a non-reference communication node and the first configuration parameter meets the predefined conditions, allocate a first number of resource blocks to the physical uplink channel corresponding to the reference physical uplink channel; wherein, the time-domain symbol length of each resource block in the first number of resource blocks and the position for transmitting the demodulation reference signal symbol are the same as those of each resource block in the second number of resource blocks in the reference physical uplink channel. Among them, the number of non-reference communication nodes is one or more.

[0070] In some examples, when the communication node is a reference communication node, it can be considered that there is already a reference physical uplink channel with time-domain resources allocated in the communication node. At this time, according to the first configuration parameter, in the physical uplink channel corresponding to the reference physical uplink channel in the communication node, newly allocate a first number of resource blocks of time-domain resources, and make the position for transmitting DMRS symbols of each resource block in the newly allocated first number of resource blocks the same as that of each resource block in the second number of resource blocks already allocated in the reference physical uplink channel.

[0071] In some examples, when the communication node is a reference communication node, it can be considered that there is already a reference physical uplink channel with time-domain resources allocated in the communication node. At this time, after receiving the first configuration parameter, judge whether it meets the predefined conditions. When the first configuration parameter meets the predefined conditions, it is considered that a new time-domain resource configuration is required for the communication node. At this time, in the physical uplink channel corresponding to the reference physical uplink channel in the communication node, newly allocate a first number of resource blocks of time-domain resources, and make the position for transmitting DMRS symbols of each resource block in the newly allocated first number of resource blocks the same as that of each resource block in the second number of resource blocks already allocated in the reference physical uplink channel.

[0072] In some examples, when the communication node is a non-reference communication node, it can be considered that there is no reference physical uplink channel with time-domain resources allocated in the communication node. At this time, according to the first configuration parameter, in the physical uplink channel with a different type from the reference physical uplink channel in the communication node, newly allocate a first number of resource blocks of time-domain resources, so that the time-domain symbol length of each resource block in the newly allocated first number of resource blocks and the position for transmitting DMRS symbols are the same as those of each resource block in the second number of resource blocks in the reference physical uplink channel in the reference communication node.

[0073] In some examples, when the communication node is a non-reference communication node, it can be considered that there is no reference physical uplink channel that has been allocated time domain resources in the communication node. At this time, it can be determined whether the first configuration parameter satisfies a predefined condition after receiving the first configuration parameter. When the first configuration parameter satisfies the predefined condition, it is considered that a new time domain resource configuration needs to be performed on the communication node. At this time, according to the first configuration parameter, for the physical uplink channels in the communication node that are different from the reference physical uplink channel type, the first number of resource blocks of time domain resources are newly allocated, so that the time domain symbol lengths of each resource block in the newly allocated first number of resource blocks and the positions for transmitting DMRS symbols are the same as those of each resource block in the second number of resource blocks in the reference physical uplink channel of the reference communication node.

[0074] It can be understood that a wireless communication system may include one or more non-reference communication nodes. The time domain resource configuration for each non-reference communication node can be implemented in the above manner. The embodiments of the present application only illustrate the cases where the current communication node is a reference communication node or a non-reference communication node.

[0075] In one embodiment, when the reference physical uplink channel is a physical uplink control channel, the physical uplink channel corresponding to the reference physical uplink channel is a physical uplink shared channel; when the reference physical uplink channel is a physical uplink shared channel, the physical uplink channel corresponding to the reference physical uplink channel is a physical uplink control channel.

[0076] In one embodiment, determining the time domain resources of the physical uplink channel of the communication node according to the third configuration parameter includes:

[0077] Instructing the physical uplink channel of the communication node to allocate the first number of resource blocks according to the third configuration parameter; wherein, the first number of resource blocks are used to transmit the demodulation reference signal of the physical uplink channel; wherein, the positions of each resource block in the first number of resource blocks for transmitting the demodulation reference signal symbols are the same as those of each resource block in the second number of resource blocks already configured in the physical uplink channel for transmitting the demodulation reference signal symbols;

[0078] Or,

[0079] When the third configuration parameter satisfies the predefined condition, allocate the first number of resource blocks for the physical uplink channel of the communication node; wherein, the first number of resource blocks are used to transmit the demodulation reference signal of the physical uplink channel; wherein, the positions of each resource block in the first number of resource blocks for transmitting the demodulation reference signal symbols are the same as those of each resource block in the second number of resource blocks already configured in the physical uplink channel for transmitting the demodulation reference signal symbols;

[0080] Wherein, the physical uplink channel of the communication node is a physical uplink shared channel or a physical uplink control channel.

[0081] In some examples, after receiving the third configuration parameter, the communication node may, in the physical uplink channel in which the second number of resource blocks have been configured in the communication node, re-allocate the first number of resource blocks for transmitting DMRS signals of the physical uplink channel, and make the positions of each resource block in the first number of resource blocks for transmitting DMRS symbols the same as the positions of each resource block in the second number of configured resource blocks for transmitting DMRS symbols.

[0082] In some examples, after receiving the third configuration parameter, the communication node may determine whether the third configuration parameter meets a predefined condition. When the third parameter meets the predefined condition, it is considered that a new time-domain resource configuration is required for the communication node. At this time, in the physical uplink channel in which the second number of resource blocks have been configured in the communication node, re-allocate the first number of resource blocks for transmitting DMRS signals of the physical uplink channel, and make the positions of each resource block in the first number of resource blocks for transmitting DMRS symbols the same as the positions of each resource block in the second number of configured resource blocks for transmitting DMRS symbols.

[0083] In one embodiment, determining the time-domain resources of the physical uplink channel of the communication node according to the fourth configuration parameter includes:

[0084] Configuring the positions for transmitting demodulation reference signal symbols in the physical uplink channel of the communication node according to the number of demodulation reference signal symbols in the fourth configuration parameter and predefined configuration information;

[0085] Or,

[0086] When the fourth configuration parameter meets the predefined condition, configuring the positions for transmitting demodulation reference signal symbols in the physical uplink channel of the communication node according to the predefined configuration information;

[0087] Wherein, the physical uplink channel of the communication node is a physical uplink control channel.

[0088] In some examples, after receiving the fourth configuration parameter, the communication node may match the number of DMRS symbols included in the fourth configuration parameter with the predefined configuration information in the communication node, and complete the configuration of the positions for transmitting DMRS symbols in the physical uplink channel of the communication node according to the matching result.

[0089] In some examples, after receiving the fourth configuration parameter, the communication node may determine whether the fourth configuration parameter meets a predefined condition. When the fourth configuration parameter meets the predefined condition, it is considered that the time-domain resources in the communication node need to be reconfigured. At this time, the configuration of the position for transmitting DMRS symbols in the physical uplink channel of the communication node can be completed according to the predefined configuration information in the communication node.

[0090] It should be clear that the configuration method in this embodiment is only applicable to the PUCCH of the communication node.

[0091] In one embodiment, determining the time-domain resources of the physical uplink channel of the communication node according to the seventh configuration parameter includes:

[0092] Configuring the time-domain resource parameters of other physical uplink channels except the physical uplink channel of the communication node in the seventh configuration parameter and the predefined configuration information to configure the time-domain resources of the physical uplink channel of the communication node;

[0093] Wherein, the physical uplink channel of the communication node is a physical uplink shared channel or a physical uplink control channel.

[0094] In some examples, after receiving the seventh configuration parameter, the communication node may match the time-domain resource parameters of other physical uplink channels except the physical uplink channel of the communication node included in the seventh configuration parameter with the predefined configuration information in the communication node, and complete the matching of the position for transmitting DMRS symbols in the physical uplink channel of the communication node according to the matching result.

[0096] Configuring the silent switch, silent pattern and whether silent supports dynamic triggering of symbol-level silence of the physical uplink channel of the communication node according to the fifth configuration parameter;

[0097] When it is determined according to the fifth configuration parameter that the silent switch of the physical uplink channel is turned on and the silent of the physical uplink channel supports dynamic triggering, determine that the silent pattern in the physical uplink channel is one of the silent patterns in the fifth configuration parameter according to the sixth configuration parameter;

[0098] Wherein, the physical uplink channel of the communication node is a physical uplink shared channel or a physical uplink control channel.

[0099] In a specific example, after receiving the fifth configuration parameter and the sixth configuration parameter, the communication node will first determine whether to enable symbol-level silent on the physical uplink channel of the communication node based on the silent switch of the symbol-level silent in the fifth configuration parameter. Furthermore, when determining that symbol-level silent is enabled, it determines which time-domain symbols are silenced according to the silent pattern in the fifth configuration parameter, and whether dynamic trigger of silent is supported. Furthermore, when determining that the physical uplink channel of the communication node supports dynamic trigger of silent, it determines the silent pattern to be applied in the physical uplink channel of the communication node according to the sixth configuration parameter, and this silent pattern should be one of the silent patterns in the fifth configuration parameter. After completing this configuration, the base station side can avoid demodulating the silent symbols during the physical uplink channel demodulation process.

[0140] UE1 receives the first configuration parameter, which is used to indicate that N RB are allocated to the PUCCH transmitted by UE1, the DMRS (and / or the uplink control information (Uplink Control Information, UCI) of UE1) is transmitted within the N RB, and the symbols used by the DMRS (and / or the UCI of UE1) are the same as the DMRS symbol positions of the PUSCH in the M RB.

[0141] In some examples, the first configuration parameter can be added to the RRC signaling. The value range of the first configuration parameter corresponds to the maximum configurable RB number of the PUCCH. When the first configuration parameter is configured, the number of PUCCH RB transmitted by UE1 can be determined as N through the value of the first configuration parameter, and the PUCCH DMRS symbol position transmitted by this UE1 is the same as the PUSCH DMRS symbol position transmitted by this UE1.

[0142] In some examples, assume that the value of the first configuration parameter in the RRC signaling is 5, the DMRS symbol positions for the UE1 to transmit PUSCH are 2 and 11, and M = 2. Then, when the UE1 transmits PUCCH, the number of RBs of the PUCCH is N = 5, and the DMRS symbol positions on these 5 RBs are also 2 and 11.

[0143] In some examples, a 1-bit first configuration parameter is added to the RRC signaling. One value of the first configuration parameter indicates that when the UE1 transmits PUCCH, it is the same as the DMRS symbol position when the UE1 transmits PUSCH. For example, assume that the value of the 1-bit first configuration parameter configured in the RRC signaling is 1, and the PUSCH DMRS symbol positions corresponding to the UE1 are 2, 7, and 11. Then, the DMRS symbol positions for the UE1 to transmit PUCCH are also 2, 7, and 11.

[0144] Solution 2: A solution for determining time-domain resources according to the received first configuration parameter is given in the case where the communication node is the UE1 and the reference physical uplink channel of the UE1 is PUCCH. It can be specifically implemented in the following manner.

[0145] For a specific UE1, M RB resources have been allocated for the PUCCH in the UE1, and the corresponding DMRS symbol positions in the M RB resources have been determined.

[0146] The UE1 receives the first configuration parameter, which is used to indicate that N RBs are allocated for the PUSCH transmitted by the UE1. The DMRS (and / or the uplink (UL) data of the UE1) of the PUSCH is transmitted within these N RBs, and the symbols used by the DMRS (and / or the UL data of the UE1) are the same as the DMRS symbol positions of the PUCCH in the M RBs.

[0147] In some examples, a 1-bit first configuration parameter is added to the RC signaling. One value of the first configuration parameter indicates that when the UE1 transmits PUSCH, it is the same as the DMRS symbol position when the UE1 transmits PUCCH. For example, assume that the value of the 1-bit first configuration parameter configured in the RRC signaling is 1, and the PUCCH DMRS symbol positions corresponding to the UE1 are 1, 5, 8, 12. Then, the DMRS symbol positions for the UE to transmit PUSCH are also 1, 5, 8, 12.

[0148] It can be understood that the method for determining the communication node type in this solution is the same as that in Solution 1, and will not be elaborated in this solution.

[0149] Solution 3: A solution for determining time-domain resources according to the received first configuration parameter is provided, where the communication node is UE2 and the reference physical uplink channel of UE1 is PUSCH. Specifically, it can be implemented in the following manner.

[0150] For a specific UE1, M RB resources have been allocated to the PUSCH in this UE1, and the corresponding DMRS symbol positions in the M RB resources have been determined.

[0151] UE2 receives the first configuration parameter, which is used to indicate that N RB resources are allocated to the PUCCH transmitted by UE2 (any one or more UEs other than UE1), the UCI of UE2 is transmitted within the N RB resources, and the DMRS symbol positions in the N RB resources are the same as the DMRS symbol positions in the M RB resources.

[0152] In some examples, a 1-bit first configuration parameter is added to the RRC signaling. The value of the first configuration parameter indicates that when UE2 transmits the PUCCH, the DMRS symbol position is the same as that of the PUSCH transmitted by UE1. For example, it can be assumed that the value of the 1-bit first configuration parameter configured in the RRC signaling is 1. The DMRS symbols of the PUSCH transmitted by UE1 are at positions 2, 7, and 11, and the time-domain symbol length is 14. Then, the time-domain symbol length of the PUCCH transmitted by UE2 is also 14, and the DMRS symbol positions of the PUCCH transmitted by UE2 are also 2, 7, and 11.

[0153] It can be understood that the method for determining the communication node type in this solution is the same as that in Solution 1, and will not be elaborated in this solution.

[0154] Solution 4: A solution for determining time-domain resources according to the received first configuration parameter is provided, where the communication node is UE2 and the reference physical uplink channel of UE1 is PUCCH. Specifically, it can be implemented in the following manner.

[0155] For a specific UE1, M RB resources have been allocated to the PUCCH in this UE1, and the corresponding DMRS symbol positions in the M RB resources have been determined.

[0156] UE2 receives the first configuration parameter, which is used to indicate that N RB resources are allocated to the PUSCH transmitted by UE2 (any one or more UEs other than UE1), the UL data of UE2 is transmitted within the N RB resources, and the DMRS symbol positions in the N RB resources are the same as the DMRS symbol positions in the M RB resources.

[0157] In some examples, a 1-bit first configuration parameter is added to the RRC signaling. One value of the first configuration parameter indicates that when UE2 transmits PUSCH, the DMRS symbol positions are the same as those of UE1 when transmitting PUCCH. For example, it can be assumed that the value of the 1-bit first configuration parameter configured in the RRC signaling is 1, the DMRS symbol positions of UE1 when transmitting PUCCH are 2 and 9, and the time domain symbol length is 13. Then the time domain symbol length of UE2 when transmitting PUSCH is also 13, and the DMRS symbol positions of UE2 when transmitting PUSCH are also 2 and 9.

[0158] It can be understood that the method for determining the communication node type in this solution is the same as that in Solution 1, and will not be elaborated in this solution.

[0159] It should be clear that for the above Solutions 1-4, the communication node can determine whether it is UE1 based on the received second configuration parameter, or can determine whether it is UE1 based on whether it has received the second configuration parameter. One value of the second configuration parameter indicates that the UE that configures this configuration parameter is the reference UE for the DMRS symbol position, that is, UE1 proposed above.

[0160] In some examples, a 1-bit second configuration parameter is added to the RRC signaling. One value of the second configuration parameter indicates that the UE that configures this configuration parameter is the reference UE for the DMRS symbol position, that is, UE1. For example, for the scenarios corresponding to Solution 3 or 4, assume that 3 UEs are configured, namely UE1, UE2, and UE3, and the value of the RRC second configuration parameter in UE1 is 1. Then it can be considered that UE1 will be the reference UE. If the values of the first configuration parameter in UE2 and UE3 are 1, then it can be considered that UE2 and UE3 need to determine new time domain resources according to the first configuration parameter. At this time, UE1 can be used as the reference UE1 for the DMRS symbol positions of UE2 and UE3. When UE2 and UE3 perform PUCCH and / or PUSCH transmissions, the DMRS symbol positions are the same as those of UE1.

[0161] Solution 5: Based on the above Solutions 1-4, the first configuration parameter can be replaced with a predefined condition, that is, when the first configuration parameter meets the predefined condition, perform the allocation of N RBs as in Solutions 1-4, and make the DMRS symbol positions in the N RBs the same as those in the M RBs.

[0162] In some examples, the predefined condition can be that the configuration parameter configured in RRC, DCI, or MAC CE is equal to a specific value or within a specific value range. The configuration parameter can be replaced with the first configuration parameter or other configuration parameters required in the corresponding solution according to the solution. The embodiments of the present application do not limit this.

[0163] In some examples, the predefined condition may be when the frequency or frequency band in the RRC parameters meets the predefined frequency domain resource range.

[0164] In some examples, the predefined condition may be that the DCI parameter value is a specific value or within a specific value range. For example, assuming that the PUCCH resource indicator parameter configured in the DCI format configures 8 PUCCH resources, the predefined condition is that the resource index of the PUCCH resource satisfies being greater than or equal to 0 and less than or equal to 4.

[0165] In some examples, the predefined condition may be the PUCCH priority. For example, the PUCCH priority is defined as 1 and 2 through the RRC parameter, and the predefined condition is the PUCCH resource with a PUCCH priority of 1.

[0166] In some examples, the above first configuration parameter, second configuration parameter, and predefined condition may be configured through RRC, DCI, or MAC CE.

[0167] It should be clear that the N RBs can be frequency domain continuous or discontinuous. N can be determined by the first configuration parameter, or determined according to the parameters in the prior art, or the same as M. The embodiments of the present application do not limit this.

[0168] It should be clear that the levels of the above first configuration parameter and second configuration parameter, as well as other possible configuration parameters in the subsequent solutions, can be not only at the UE level, but also at the UL BWP level, PUCCH resource and / or PUSCH time domain resource configuration level, PUCCH format level, and cell level, etc., to adapt to the physical uplink channel time domain resource configuration requirements of different communication nodes. The embodiments of the present application do not limit this.

[0169] Solution 6: A solution for determining the time domain resource according to the received third configuration parameter is given in the case where the configured physical uplink channel in the communication node UE is PUCCH. It can be specifically implemented in the following manner.

[0170] Assume that M RB resources are allocated to the PUCCH in the UE, and the corresponding DMRS symbol positions in the M RB resources are determined.

[0171] The UE receives the third configuration parameter, which is used to indicate that N RBs are added to the PUCCH transmitted by the UE. The PUCCH DMRS of the UE is transmitted within the N RBs, and the symbol positions used by the DMRS are the same as the DMRS symbol positions in the M RBs.

[0172] In some examples, the third configuration parameter may be an RRC parameter, which is used to indicate the number of newly added RBs for DMRS. For example, assume that the number of configured RBs in the UE is 1, the starting position of the RB is 0, the DMRS symbol positions are 3 and 10. The configuration parameter 3 in the RRC signaling is used to indicate that the number of newly added RBs is 3 and the starting position of the RB is 1. Then, the DMRS of the UE is transmitted at the time domain symbol positions 3 and 10 on the RB indexes 0 to 3, and the data transmission of the UE is only on the time domain symbols 0, 1, 2, 4, 5, 6, 7, 8, 9, 11, 12, 13 on the RB index 0.

[0173] In some examples, the third configuration parameter may be an additional bit parameter in the PUCCH resource indicator configured by the DCI format, which is used to indicate the number of added RBs N for the corresponding PUCCH resource. For example, the original value of the bit parameter of the PUCCH resource indicator configured by the DCI format is '000', and 4-bit configuration parameter 3 is added, and the value of this configuration parameter is '0011', which means that the number of added RBs N on the PUCCH resource 0 is 3.

[0174] Solution 7: Based on the above Solution 6, the third configuration parameter can be replaced by a predefined condition, that is, when the third configuration parameter meets the predefined condition, the PUCCH transmitted by each UE adds N RBs, and the PUCCH DMRS of the UE is transmitted within these N RBs, and the symbol positions used by this DMRS are the same as the DMRS symbol positions in the M RBs.

[0175] It should be clear that the predefined condition in this solution can be the same as the predefined condition proposed in Solution 5.

[0176] It should be clear that the N RBs can be frequency-domain continuous or discontinuous. The time domain symbol positions of the non-DMRS in the N RBs can be used for the transmission of other channels of UE1, or for the transmission of other UEs and / or other channels, or can be used as time domain idle symbols without being used for the transmission of any channel. N can be determined by the third configuration parameter, or can be determined according to the parameters in the existing technology, or can be the same as M.

[0177] It should be clear that the third configuration parameter and the predefined condition can be configured through RRC, DCI or MAC CE.

[0178] Solution 8: A solution for determining the time domain resources according to the received fourth configuration parameter is given in the case where the configured physical uplink channel in the communication node UE is PUCCH. Specifically, it can be implemented in the following manner.

[0179] Assume that M RB resources have been allocated to the PUCCH in the UE, and the corresponding DMRS symbol positions in the M RB resources are determined.

[0180] The UE receives a fourth configuration parameter, which is used to indicate the time-domain symbol positions of L DMRS symbols configured by the UE during PUCCH transmission. Among them, the value of L can be a positive integer greater than 0 and less than or equal to 7.

[0181] In some examples, a fourth configuration parameter is added to the RRC signaling. The fourth configuration parameter includes the number of DMRS symbols as L and the preconfigured table index I. The fourth configuration parameter is used to determine the time-domain resource configuration of the PUCCH when the number of DMRS symbols is specified.

[0182] In some examples, when the number of PUCCH DMRS symbols L = 3, the DMRS symbol positions for PUCCH transmission can be determined according to the table index I. The preconfigured tables are shown in Tables 3 and 4 below:

[0183] Table 3: DMRS symbol positions corresponding to the case where the number of DMRS symbols L = 3 and the table index I = 0

[0184]

[0185] Table 4: DMRS symbol positions corresponding to the case where the number of DMRS symbols L = 3 and the table index I = 1

[0186]

[0187]

[0188] As shown in the first DMRS symbol position l0 in Tables 3 and 4 above, it can be determined by the fourth configuration parameter or based on the configuration parameters of the PUSCH.

[0189] Solution 9: Based on the above Solution 8, the fourth configuration parameter can be replaced with a predefined condition. That is, when the fourth configuration parameter meets the predefined condition, the positions of the DMRS symbols in the PUCCH are determined according to the predefined configuration.

[0190] It should be clear that the predefined condition in this solution can be the same as the predefined condition proposed in Solution 5.

[0191] In some examples, the predefined configuration can be a predefined time-domain resource configuration or one or more PUSCH configurations configured in the pusch-TimeDomainAllocationList of the RRC parameter configuration in the prior art.

[0192] In some examples, assume that the predefined condition is that the PUCCH resource index range corresponding to the PUCCH resource indicator in the DCI format is 0 to 2, and the predefined time-domain resource configuration is that the DMRS symbol position takes values of 2, 7, and 11. Then when the PUCCH resource index takes values of 0, 1, and 2, the DMRS symbol positions corresponding to the PUCCH transmission are 2, 7, and 11.

[0193] It should be clear that the fourth configuration parameter and the predefined condition can be configured through RRC, DCI, or MAC CE.

[0194] Solution 10: Given that the configured physical uplink channel in the communication node UE is PUCCH, a solution for determining the time-domain resources of PUCCH based on symbol-level silence in the UE according to the received fifth configuration parameter and sixth configuration parameter is presented. It can be specifically implemented in the following manner.

[0195] Assume that M RB resources have been allocated to the PUCCH in the UE, and the corresponding DMRS symbol positions in the M RB resources have been determined.

[0196] PUCCH supports symbol-level muting, thereby solving the time-domain conflict of PUCCH with other channels at some time-domain symbol positions or avoiding symbol-level interference on some time-domain symbols.

[0197] When symbol-level muting is enabled, determine which time-domain symbols are muted according to the muting pattern. One or more muted time-domain symbols corresponding to the muting pattern are called muted symbols.

[0198] The UE side does not transmit PUCCH on the muted time-domain symbols; when the base station side demodulates PUCCH, the muted time-domain symbols are not demodulated.

[0199] In some examples, the UE can receive the fifth configuration parameter, which includes a muting switch, a muting pattern, and whether muting supports dynamic triggering. At the same time, the UE can also receive the sixth configuration parameter, which is used to indicate the index or identifier Indicator of the muting pattern.

[0200] In some examples, the fifth configuration parameter can be a configuration parameter in the RRC signaling.

[0201] In some examples, the sixth configuration parameter can be configured through DCI or MAC CE, or can also be configured through RRC signaling.

[0202] In some examples, assume that when the UE performs PUCCH transmission, the fifth configuration parameter in the RRC signaling has the silent switch turned on, the silent patterns are '01001', '1001', and silent supports dynamic triggering. Then, when the silent pattern identifier indicated by the sixth configuration parameter in the DCI is '01', during the UE's PUCCH transmission, the time-domain symbols with symbol indices 1 and 4 are silent. When the base station performs PUCCH demodulation, it does not perform demodulation processing on the PUCCH on symbols 1 and 4. When the silent pattern identifier is '00', PUCCH symbol-level silence is not performed.

[0203] In some examples, assume that when the UE performs PUCCH transmission, the fifth configuration parameter in the RRC signaling has the silent switch turned on, the silent patterns are '01001', '1001', and silent does not support dynamic triggering. Then, when the silent pattern identifier indicated by the sixth configuration parameter in the RRC signaling is '02', the time-domain symbols of the PUCCH transmitted by the UE are silent on symbol indices 0 and 3. When the base station performs PUCCH demodulation, it does not perform demodulation processing on the PUCCH on symbols 0 and 3.

[0204] In some examples, when the configuration parameters corresponding to the fifth and sixth configuration parameters take effect, during the process of the UE generating the PUCCH signal, the rate matching and code rate calculation are processed according to the number of non-silent symbols. When the base station performs the corresponding PUCCH demodulation, it does not perform demodulation processing on the silent symbols.

[0205] In some examples, when the configuration parameters corresponding to the fifth and sixth configuration parameters take effect, during the process of the UE generating the PUCCH signal, UCI time-domain symbol mapping and subsequent processing are not performed on the silent symbols. When the base station performs the corresponding PUCCH demodulation, it does not perform demodulation processing on the silent symbols.

[0206] It should be clear that the symbol-level silence in Solution 10 also applies to PUSCH.

[0207] Solution 11: Presents a solution for an extended common Common PUCCH resource configuration table to more flexibly configure the common PUCCH time-domain resources. Its handling method is similar to that of Solution 8, but the difference lies in the different information contained in the configuration parameters received by the UE. It can be specifically implemented as follows.

[0208] The UE receives the seventh configuration parameter. One value of this seventh configuration parameter indicates that based on the physical layer uplink channel, including but not limited to PUSCH / SRS / PRACH, according to the time-domain resource configuration in the physical layer uplink channel resource configuration, it is mapped to one of the increased multiple common PUCCH resource configuration tables, and the time-domain resource configuration of the common PUCCH is determined based on this table.

[0209] It should be clear that the above method is equally applicable to the resource configuration of dedicated PUCCH.

[0210] In some examples, the seventh configuration parameter may be a 1-bit configuration parameter configured in the RRC parameters. One value of the seventh configuration parameter represents one of multiple public PUCCH resource configuration tables added correspondingly based on the SRS start symbol position and the number of SRS symbols in the RRC signaling.

[0211] In some examples, assuming that the value of the seventh configuration parameter in the RRC signaling is 1, when the SRS start symbol position in the RRC signaling is 13 and the number of symbols is 1, the corresponding newly added public PUCCH resource configuration table. The specific public PUCCH resource configuration table is shown in Table 5 below:

[0212] Table 5: Public PUCCH resource configuration corresponding to SRS start symbol position of 13 and number of symbols of 1

[0213]

[0214]

[0215] In some examples, when the SRS start symbol position in the RRC signaling is 12 and the number of symbols is 2, the corresponding newly added public PUCCH resource configuration table. The specific public PUCCH resource configuration table is shown in Table 6 below:

[0216] Table 6: Public PUCCH resource configuration corresponding to SRS start symbol position of 12 and number of symbols of 2

[0217]

[0218] In some examples, when the SRS start symbol position in the RRC signaling is 10 and the number of symbols is 4, the corresponding newly added public PUCCH resource configuration table. The specific public PUCCH resource configuration table is shown in Table 7 below:

[0219] Table 7: Public PUCCH resource configuration corresponding to SRS start symbol position of 10 and number of symbols of 4

[0220]

[0221]
