detailed description

Hereinafter, the embodiments of the present application will be described in detail with reference to the drawings.

The scenarios in which multiple sets of transmission resources need to be configured in the embodiment of the application include but are not limited to the following:

Scenario 1: Ensure the reliability and delay of the same service of the same UE.

When configuring and activating a set of transmission resources for the same service of the same UE, the arrival time sequence (Time Order n, TOn) at this time lags behind the first time sequence (TO1) due to the lag in service arrival, which cannot satisfy K repeated transmissions Or increased alignment delay. For this reason, the base station provides multiple sets of transmission resources for the user equipment. The multiple sets of transmission resources have time-domain offset or frequency-domain offset or time-frequency domain offset. Between time sequences, it is possible to select a transmission resource that satisfies K repeated transmissions or the minimum delay from multiple sets of transmission resources for transmission, so as to ensure the reliability and delay of the same service of the same UE.

For the multiple sets of transmission resources configured by the base station for the user equipment, refer to the examples in Figures 1-1 to 1-3. A transmission resource set can include one or more sets of resources. Wherein, the offset mode of the transmission resource set containing multiple sets of resources in the set may be one of: time domain offset, frequency domain offset, and time-frequency domain offset. The configuration modes of the offset mode include the following two: Configuration mode 1 is: multiple sets of transmission resources in a group use one offset mode, and multiple resource groups belonging to the same set use the same offset mode. Configuration method 2: Each set of transmission resources in a group adopts an offset method, and each resource group in the same set adopts an offset method. Among them, the offset of configuration method 1 is relative to the first set of transmission resources in the group, and the offset size of a set of resources in the resource group is the position of the resource in the resource group (the Nth set) minus 1 times the configuration Offset granularity. The granularity of resource configuration can be: if it is time domain offset, the offset granularity can be N symbol length or M TO length or L time slot length (N, M, L are positive integers); if it is frequency domain offset , Then the offset granularity can be I resource block (Resource Block, RB) or J resource block group (Resource Block Group, RBG) or K part of the bandwidth (I, J, K are integers); if it is in the time-frequency domain Offset, the offset granularity is a combination of the above-mentioned time domain offset and frequency domain offset granularity. For example: Set 1 in Figure 1-1 includes 4 sets of transmission resources, #1, #2, #3, and #4. The offset mode between transmission resources in the group is time domain offset, and the configured time domain offset size is assumed to be N symbols or a TO length, then the offset of transmission resource #1 is 0 (no offset); transmission The offset of resource #2 is N symbols or one TO transmission length to the right; the offset of transmission resource #3 is 2N symbols or 2 TO transmission length to the right; the offset of transmission resource #4 is Offset 3N symbols or 3 TO transmission length to the right. A downlink control information (DCI, Downlink Control Information) is used to activate the resources included in the group, and the 4 sets of transmission resources in the set 1 are activated, and the DCI contains the information indication of the group identification of the set 1. Set 2 in Figure 1-2 includes 2 sets of transmission resources, #1 and #2 respectively. The offset mode between transmission resource #1 and transmission resource #2 is frequency domain offset, and the configured offset granularity is N RBs, then the offset of #1 resource is 0 (no offset), and the offset of #2 resource is It is shifted up or down by N RB sizes. Use one DCI signaling to activate multiple sets of resources included in the set of resources, and activate two sets of transmission resources in the set 2, and the DCI contains the information indication of the set 2 group identifier. Set 3 in Figure 1-3 includes transmission resource #1. Since there is only one set of transmission resources, there is no need to indicate the offset mode in the group.

If RRC signaling configures four sets of transmission resources #1, #2, #3, and #4. The configured transmission resource may include or not configure the offset mode of each set of resources. If there is no offset mode in the configuration. At this time, grouping can be performed through RRC or the four sets of transmission resources can be configured into different states. There are one or more sets of resources in the same state. It is also possible to group the four sets of transmission resources through MAC CE signaling or configure the four sets of transmission resources into different states. For example, transmission resource #2 and transmission resource #3 in the original RRC signaling configuration are configured into a group (one state). In addition, according to the offset configuration method 1, one offset method is configured in one group (one state), and the offsets of multiple sets of resources are all offset based on the first set of resources. According to the offset configuration mode 2, the offset granularity and offset mode of each set of resources can be configured through RRC signaling or MAC CE signaling, and the offset is performed according to the indicated offset mode. For example, the following configurations are configured through RRC signaling: #1+offset1 (offset1), #2+offset2, #3+offset3 and #4+offset4 four sets of configurations. That is, the base station configures the corresponding offset mode for the resource when configuring the resource. Alternatively, the transmission resources included in a group or the transmission resources included in a state are directly configured through RRC signaling, and then the offset mode of the transmission resources in each group or each state is indicated through MAC CE signaling. That is, the base station does not configure an offset mode for resources when configuring resources. If resources need to be offset during activation, they can be configured accordingly through MAC CE. Finally, when activating transmission resources in a group or a state, one activation signaling can activate all resources in a group or a state at the same time, and multiple sets of resources in the group or state can be set according to the offset in the configuration. Offset between resources.

In the embodiment of the present application, the parameter configuration of multiple sets of resources in the resource set or resource group may be the same. Similarly, the parameter configuration of multiple sets of resources in a set or a group may also be different. In addition, the same set of resources can be configured in multiple resource collections or resource groups, and multiple sets of the same configuration resources can also be configured in a resource group or resource collection.

Scenario 2: UE supports multiple QoS service requirements.

In the scenario where the UE supports multiple types of dispatch-free transmission services, even the same UE has different performance requirements for different service types. Therefore, for each service type, the base station can correspondingly configure one or more sets of transmission resources for the user equipment.

Scenario 3: Avoid resource collisions between UEs in the inter-user equipment (Inter-UE) multiplexing scenario.

Exemplarily, two service scenarios of enhanced mobile broadband (eMBB, Enhanced Mobile Broadband) and low-latency and highly reliable communication (URLLC, Ultra Reliable & Low Latency Communication) are reused between user equipment. For example, a collision occurs between the transmission resource scheduled for eMBB and the scheduling-free transmission resource configured for URLLC. In order to avoid collisions, the base station can configure multiple sets of resources for the UE. The multiple sets of resources have multiple offset modes such as frequency domain offset or time domain offset. Refer to Figure 2 to configure four sets of scheduling-free resources for URLLC, namely #1, #2, #3, and #4. The dashed box represents the resources scheduled by eMBB. The dashed box overlaps resource #3 and resource #4. If only resource #3 or resource #4 is configured for the URLLC service of the user equipment, when the user equipment performs eMBB and URLLC services at the same time, the resources scheduled by the eMBB service collide with the scheduling-free resources of the URLLC service. However, if the base station configures the resources #1, #2, #3, and #4 in Figure 2 for the URLLC service of the user equipment, when the user equipment performs eMBB and URLLC services at the same time, the user equipment may avoid sending collisions. The configuration of resource #1 or #2 can be selected for URLLC transmission. Among them, the frequency domain offset between the scheduling-free resources #1, #2, #3, and #4.

In the embodiments of this application, the configuration and activation of non-scheduling resources include but are not limited to two ways: Type 1, the parameters are configured by radio resource control (RRC, Radio Resource Control) signaling, and the RRC signaling allocates resource parameters to UE, resources are automatically activated. Type 2: RRC signaling configures some parameters of a set of resources, the remaining parameters are indicated in DCI signaling, and the set of resources is activated by DCI signaling.

For the type 2 method, the resources configured by RRC signaling are activated by DCI signaling, and each set of resources requires one DCI signaling to activate. However, in a scenario where the delay and reliability of the same service of the same user are guaranteed, the DCI signaling overhead is relatively large. In order to reduce the DCI information, one DCI can be used to activate multiple sets of resources at the same time.

Referring to FIG. 3, a resource configuration method provided by an embodiment of the present application will be described below. The embodiments of the present application may be applied to equipment on the transmitting side, such as a base station. In the embodiments of the present application, the device on the receiving side may include user equipment. The embodiment of the present application will take the interaction between the base station and the user equipment as an example to describe the solution provided in the present application. The embodiment of the present application includes step S110 and step S120, as follows:

S110: Send configuration information of transmission resources to the user equipment, where the configuration information includes parameter configuration information of multiple sets of transmission resources allocated to the user equipment.

S120: Send activation information of the transmission resource to the user equipment, where the activation information includes an identifier of the transmission resource that needs to be activated, and the identifier is used to activate the transmission resource.

In some embodiments, the configuration information may include the set identification information of multiple sets of transmission resources, and in step S120, the activation information including the set identification may be sent to the user equipment. When the user equipment receives the activation information, it uses the set identifier to activate the transmission resource. Correspondingly, the base station may also send the deactivation information including the set identifier to the user equipment. The user equipment can use the set identifier in the deactivation information to deactivate the corresponding transmission resource.

Exemplarily, the base station configures 4 sets of transmission resources for the user equipment, which can be sorted by sequence numbers, including transmission resources with sequence numbers #1 to #4. These configured resources are activated through DCI signaling, and the DCI signaling includes information for indicating the set identifier. For example, a 2-bit field is used to indicate a set identifier, 00 represents a transmission resource of sequence number #1; 01 represents a transmission resource of sequence number #2; 10 represents a transmission resource of sequence number #3; 11 represents a transmission resource of sequence number #4. The number of bits of the bit field used in the activation information may satisfy the following condition: the maximum integer value that the bit field can express is greater than or equal to the highest sequence number value in the transmission resource. If the set identification bit field used to indicate a specific transmission resource in the activation information is smaller than the currently configured number of resource sets, the value indicated by the set identification bit field can correspond to the ordered transmission resources in a one-to-one order.

In some embodiments, in addition to parameter configuration information of multiple sets of transmission resources, the configuration information may also include grouping information. The grouping information includes multiple resource groups composed of multiple sets of transmission resources. The resource group includes at least one set of transmission resources. A resource group has a group ID, and a set of transmission resources has a set ID. In step S120, the base station may send activation information including at least one of the group identifier and the set identifier to the user equipment. If the activation information only includes the set identification, the user equipment activates one of the multiple sets of transmission resources. If the activation information includes the group identifier, the user equipment activates all transmission resources in a resource group corresponding to the group identifier. If the activation information includes the group identification and the set identification, the user equipment activates a set of transmission resources corresponding to the set identification in the resource group associated with the resource group. In the embodiments of the present application, one activation message may be used to activate multiple sets of transmission resources, thereby reducing information transmission overhead.

Exemplarily, the base station configures 8 sets of transmission resources for the user equipment through RRC signaling, which are sorted by sequence numbers, including transmission resources with sequence numbers #1 to #8. The base station divides these 8 sets of transmission resources into 4 groups through Medium Access Control Element (MAC CE, Medium Access Control Element) signaling or RRC signaling, as shown in Table 1 below.

Table 1

Group number	Resources in the group
1	#1
2	#4
3	#1, #6, #7, #8

4	#1, #2, #3, #5

At this time, the activation information includes a corresponding bit field for indicating the group identification, that is, the group sequence number in Table 1. For example, 2bit, 00 represents the resource group of sequence number 1; 01 represents the resource group of sequence number 2; 10 represents the resource group of sequence number 3; 11 represents the resource group of sequence number 4. The number of bits of the bit field used in the activation information may satisfy the following condition: the largest integer value that the bit field can express is greater than or equal to the highest sequence number value in the resource group. Such an activation message can activate all resources in a group at the same time.

The activation information can also use the corresponding bit field to indicate a set of resources activated in the group, that is, the set identification bit field. For example, Table 1 includes 8 sets of resources, the transmission resources with serial numbers #1 to #8. Then the activation information can use 3 bits to represent the set of identification. Among them, the value expressed by 3bit corresponds to the serial number of the same value one by one.

If DCI signaling is used to transmit activation information, a DCI includes a 2-bit group identification indicator field, such as 01, which indicates that all resources in the resource group with sequence number 1 need to be activated. If a DCI contains a 2-bit group identification indicator field and a 3-bit set identification indicator field, such as 10 and 101, it means that a set of transmission resources with sequence number #6 in the resource group with sequence number 1 needs to be activated.

In some embodiments, the method provided in the embodiments of the present application further includes: sending transmission resource deactivation information to the user equipment, and the deactivation information includes the identification of the transmission resource that needs to be deactivated, so that the user equipment uses the identification to pair the transmission resource go activate.

If the user equipment no longer needs to use the activated transmission resources, the base station may send deactivation information to the user equipment. When the user equipment receives the deactivation information, it uses the identifier in the deactivation information to deactivate the corresponding transmission resource.

Wherein, if the identifier in the deactivation information only includes the set of identifiers, the transmission resource corresponding to the set of identifiers is deactivated. If the identifier in the deactivation information includes a group identifier, all transmission resources in the resource group corresponding to the group identifier are deactivated. If the identifier in the deactivation information includes a group identifier and a set identifier, the transmission resource corresponding to the set identifier in the resource group corresponding to the group identifier is deactivated. The embodiment of the present application may use one deactivation message to deactivate multiple sets of transmission resources.

In some embodiments, the base station may use RRC signaling and DCI signaling to configure resources and activate resources for the UE. Referring to FIG. 4, an embodiment of the present application provides a method for resource configuration and activation, including steps S21 and S22, as follows:

S21: Send first indication signaling to the user equipment, where the first indication signaling includes parameter configuration information and grouping information.

S22: Send activation information to the user equipment, where the activation information includes the group identifier of the transmission resource that needs to be activated, and the group identifier in the activation information is used to activate the transmission resource associated with the group identifier. Wherein, the transmission resource associated with the group identifier may be multiple sets of transmission resources in the resource group corresponding to the group identifier. For example, if the group identifier in the activation information is binary "10", and the corresponding decimal value is 3, the user equipment activates all transmission resources in the third resource group.

In this embodiment, the base station can configure multiple sets of transmission resources for the user equipment through RRC signaling, such as scheduling-free resources, used for physical uplink shared channel (PUSCH, Physical Uplink Share Channel) or physical downlink shared channel (PDSCH, Physical Downlink). Share Channel) and other channels for data transmission. Multiple sets of transmission resources in RRC signaling are allocated in multiple resource groups, and each group of resources corresponds to a sequence number, which represents a group identifier. Among them, a resource in a resource group corresponds to a QoS service requirement of the UE. Multiple resource groups can meet multiple QoS service requirements of the UE. A resource group can include one or more sets of transmission resources. If the resource group includes multiple sets of resources, there is an offset between the multiple sets of resources. The offset may include one of time-domain offset, frequency-domain offset and time-frequency offset. In some embodiments, when multiple sets of resources are included in a resource group, the parameters of the multiple sets of resources in the group can be configured independently, or the parameters of one set of resources can be expanded to obtain other sets of resources in the group. Resources. The base station sends RRC signaling to the user equipment, and can configure parameter configuration information and grouping information of multiple sets of transmission resources. The grouping information may include a group ID and at least one set of IDs associated with the group ID. In the case where resources need to be activated, the base station sends DCI signaling to the user equipment, and the DCI signaling may carry the group identifier, or the group identifier and the set identifier. The DCI signaling can use a bit field to characterize a specific identifier. When the user equipment receives the DCI signaling, it activates all transmission resources or a specified set of transmission resources in the corresponding resource group.

Wherein, if the grouping information includes multiple optional offset modes between multiple sets of transmission resources in the group, DCI signaling may be used to indicate the specific offset modes between transmission resources in the group. Alternatively, the DCI signaling can distinguish multiple offset modes through different radio network temporary identity (RNTI, Radio Network Temporary Identity) and scrambling, so as to indicate a specific offset mode. If the grouping information only includes the offset mode of multiple sets of transmission resources in a group, the offset mode does not need to be indicated in the DCI signaling. When the user equipment receives the DCI signaling, while activating multiple sets of transmission resources in the corresponding resource group, it shifts the activated multiple sets of transmission resources according to the offset mode indicated by the DCI signaling. The offsets between multiple sets of resources in the group are all offsets for the first set of resources. The offset mode may include one of time domain offset, frequency domain offset, or time-frequency domain offset.

In some embodiments, MAC CE signaling may also be used to select some or all groups from multiple group resources configured by RRC signaling, and indicate the offset mode between multiple sets of resources in the group. And use DCI signaling to activate multiple sets of transmission resources or one set of transmission resources in the resource group. Referring to Fig. 5, an embodiment of the present application provides a method for resource configuration and activation. This embodiment includes steps S31 to S33, as follows:

S31: Send first indication signaling to the user equipment, where the first indication signaling includes parameter configuration information and grouping information.

S32: Send second indication signaling to the user equipment. The second indication signaling includes one of the following: multiple group identities of transmission resources to be activated, multiple group identities and resource groups to which multiple group identities are mapped respectively. For example, the second indication signaling includes group identities G1, G2, and G3. For another example, the second indication signaling includes group identifiers G1, G2, and G3, and also includes resource group G5 mapped by group identifier G1, resource group G6 mapped by group identifier G2, and resource group G7 mapped by group identifier G3.

S33: Send activation information to the user equipment, the activation information includes the group identifier of the transmission resource that needs to be activated in the second indication signaling, and the group identifier in the activation information is used to activate the transmission resource associated with the group identifier. Following the previous example, if the activation information includes the group identifier G1, at this time, the user equipment activates the resource group G5 mapped by the group identifier G1.

In this embodiment, the base station configures multiple sets of transmission resources for the UE through RRC signaling, such as scheduling-free resources, for data transmission on channels such as uplink PUSCH or PDSCH. Each set of scheduling-free transmission resources corresponds to a set of independent parameter configuration information, and each set of transmission resources can correspond to a sequence number to indicate the set identification. When needed, the base station can configure the previously configured multiple sets of transmission resources into multiple resource groups through RRC signaling, and the resource groups can include one or more sets of transmission resources. Among them, the same set of resources can be configured in different groups, and the configuration offset between multiple sets of resources in the group. The configuration is performed according to the above-mentioned offset configuration mode 1: the offset mode may include one of time domain offset, frequency domain offset, or time-frequency domain offset. The offset is the first set of transmission resources in the relative group. For example, the group includes three sets of resources #1, #2, and #3, and the three sets of resources correspond to one offset. It can be indicated as: #1, 2, 3+offset. Or, configure according to the above-mentioned offset configuration mode 2: each set of resources in the group is configured with an offset, and the offset mode may be one of time domain offset, frequency domain offset, or time-frequency domain offset. For example, the group includes three sets of resources #1, #2, and #3, and the three sets of resources each correspond to an offset. It can be indicated as: #1+offset, #2+offset, #3+offset.

In some embodiments, the base station may also send parameter configuration information and grouping information of multiple sets of transmission resources to the user equipment simultaneously through one RRC signaling. Wherein, the parameter configuration information may or may not include the offset information of each set of resources. If RRC signaling configures multiple sets of transmission resource parameter configuration information, each set of resources is configured with resource offset information, and the offset information may no longer be configured when the subsequent information indicates.

When needed, the base station can select part or all of the multiple resource groups configured by the RRC signaling through MAC CE signaling and indicate the offset mode between multiple sets of resources in the group. Among them, the MAC CE signaling can establish a new order for the selected resource groups, and each resource group includes a corresponding set identifier. Alternatively, the MAC CE signaling maps the new group identifier of the selected resource group with the group identifier of this resource group in the original RRC signaling. The user equipment can save this mapping relationship, and when activating, find the resource group to be activated according to the mapping relationship.

In some embodiments, when RRC signaling configures grouping information, one or more optional offset modes can be configured for multiple sets of resources in the group. If only one offset mode is configured for RRC signaling, the corresponding MAC CE signaling or DCI signaling does not need to indicate the offset mode. If multiple offset modes are configured for RRC signaling, MAC CE signaling or DCI signaling needs to select an offset mode from them.

When needed, the base station activates the resource group indicated by the MAC CE through DCI signaling, and the DCI contains a bit field for indicating the group identity, such as a group sequence number or a set sequence number. This group sequence number or set sequence number can be the sequence number indicated by MAC CE. If this resource group includes multiple sets of resources, DCI activates multiple sets of resources in the group at the same time. If the DCI also includes a corresponding bit field for indicating the set identifier of the activated transmission resource in a specific resource group, then activate a set of transmission resources corresponding to the bit field in the resource group.

Exemplarily, the base station configures 8 sets of transmission resources for the user equipment through RRC signaling, which can be sorted by sequence number, including transmission resources with sequence numbers #1 to #8. And through RRC signaling, 8 sets of transmission resources are grouped into 8 resource groups, as shown in Table 2 below.

Table 2

Group number	Resources in the group
1	#1
2	#4
3	#1, #6, #7, #8
4	#1, #2, #3, #5
5	#5
6	#6
7	#7
8	#1, #1, #1, #1

Suppose that a 2-bit group identification indicator field is configured in the DCI signaling, and the fifth group or resource group with a group sequence number greater than 5 needs to be activated. At this time, if the base station sends DCI directly in the case of the above divided groups, it cannot be directly Activate the 5th group or the resource group whose group number is greater than 5. To this end, in this embodiment, MAC CE signaling may be used to select a resource group that needs to be activated among the eight resources configured by RRC signaling for mapping. Exemplarily, the MAC CE signaling selects the resource groups whose original group sequence numbers are 4, 5, 6, and 7 among the 8 groups of resources configured by RRC, as shown in Table 3 below.

table 3

Regarding the situation where there are resource groups including multiple sets of transmission resources in the resource group indicated by the MAC CE signaling, the MAC CE signaling can select or indicate a specific offset mode from a variety of offset modes configured by the RRC signaling. For example, RRC configures two optional offset modes: frequency domain offset and time domain offset. The MAC CE signaling indicates the specific offset mode used, such as frequency domain offset. If RRC is configured with an offset mode, the MAC CE signaling does not indicate the specific offset mode used.

At this time, the DCI signaling can use a 2-bit group identifier indication field, and the group sequence number indicated by the deactivated MAC CE is any one of the resource groups 1, 2, 3, and 4. Among them, the group serial numbers indicated by the MAC CE establish a one-to-one mapping relationship with the original group serial numbers 4, 5, 6, and 7 in the sequence of arrangement. If the group identifier indication field included in the DCI signaling is 11, the resource group of the group sequence number 4 indicated in the MAC CE can be activated. The group sequence number 4 and the original group sequence number 7 indicated by the MAC CE are mapped to each other, that is, the original group number 7 can be activated. The resource group of sequence number 7. Therefore, in the embodiment of the present application, some RRC configuration parameters can be modified through MAC CE, so as to reduce the signaling overhead in activating DCI.

In some embodiments, the base station may use RRC signaling, MAC CE signaling, and DCI signaling for resource configuration and activation. Referring to FIG. 6, an embodiment of the present application provides a resource configuration and activation method, including steps S41 to S43, as follows:

S41: Send first indication signaling to the user equipment, where the first indication signaling includes parameter configuration information.

S42: Send second indication signaling to the user equipment, where the second indication signaling includes grouping information.

S43: Send activation information to the user equipment, the activation information includes the group identifier of the transmission resource that needs to be activated, and the group identifier in the activation information is used to activate the transmission resource associated with the group identifier.

In this embodiment, the base station configures multiple sets of scheduling-free transmission resources for the UE through RRC signaling, and the scheduling-free transmission resources are used for channel transmission such as uplink PUSCH or downlink PDSCH. Among them, each set of scheduling-free transmission resources corresponds to a set of independent parameter configuration information, and each set of resources can correspond to a sequence number to indicate the set identification. When needed, the base station configures part or all of the multiple sets of scheduling-free resources into different resource groups or resource sets through MAC CE signaling. Each resource group or resource collection corresponds to a serial number to indicate the group ID or collection ID.

If the resource group includes multiple sets of transmission resources, MAC CE signaling can configure offsets between multiple sets of transmission resources for this resource group. The embodiments of the application are not limited to using MAC CE signaling to supplement or modify information configured by RRC signaling, and RRC signaling may also be used to supplement or modify information configured by previous RRC signaling. Wherein, the offset configuration can be performed in accordance with the aforementioned offset configuration mode 1 or configuration mode 2.

In some embodiments, the base station may configure the offset mode of multiple sets of transmission resources in the group through RRC signaling or provide multiple optional offset modes. In the following, according to the offset configuration method 1, the base station can select one of the offset modes configured in the RRC signaling through MAC CE signaling as the offset mode of the resource group containing multiple sets of transmission resources. Shift mode. Or, according to offset configuration mode 2, the base station can select an offset mode for each set of transmission resources in the resource group from multiple offset modes configured in RRC signaling through MAC CE signaling.

When activation is required, the base station sends DCI signaling to the user equipment, and the signaling includes an indication field of the group identifier. Through the DCI, all transmission resources in the resource group associated with the group identifier can be activated. The signaling may also include the set identifier, and the user equipment may activate the transmission resource corresponding to the set identifier in the resource group associated with the group identifier.

Exemplarily, the base station configures 8 sets of resources for the UE through RRC signaling, which are #1, #2, #3, 4#, 5#, 6#, 7#, and 8#. The 8 sets of resources in RRC signaling are configured into 4 groups through MAC CE signaling, and each group includes one or more sets of identifiers, as shown in Table 4 below.

Table 4

Group number	Resources in the group
1	#1
2	#4
3	#1, #6, #7, #8
4	#1, #2, #3, #5

Since the number of resource groups is 4 groups, DCI can set a 2-bit field (2bit) to represent the group identifier. Among them, 00 represents group number 1, 01 represents group number 2, 10 represents group number 3, and 11 represents group number 4. For example, if the group identification bit field of 11 is included in the DCI signaling, the user equipment activates the resource group with the group sequence number 4. Since the configured resource includes 8 sets, a 3-bit field (3bit) can be set in the DCI to indicate the set identifier. Among them, 000 represents the serial number 1, 001 represents the serial number 2, 010 represents the serial number 3, 011 represents the serial number 4, 100 represents the serial number 5, 101 represents the serial number 6, 110 represents the serial number 7, and 111 represents the serial number 8. For example, if the DCI includes a group identification bit field of 11 and a set of identification bit field of 100, the user equipment activates the fifth set of transmission resources in the fourth resource group.

In some embodiments, if the set identification bit field used to indicate a specific resource group in the activation information is less than the number of resource sets in the group, then the value represented by the set identification bit field corresponds in order to the transmission resources in the group in order. . For example, DCI uses 2 bits to represent the set identifier. If the DCI indicates to activate the 4th resource group, as shown in Table 4, the 4th resource group includes the transmission resources of #1, #2, #3 and #5, then 00 represents the set number# in the 4th resource group 1, 01 represents the set number #2 in the fourth resource group, 10 represents the set number #3 in the fourth resource group, and 11 represents the set number #5 in the fourth resource group.

In some embodiments, the activation information not only includes the group identifier of the transmission resource that needs to be activated, but also includes the set identifier of the transmission resource that needs to be activated. Then, after receiving the activation information, the user equipment activates the transmission resource corresponding to the set identifier in the resource group associated with the group identifier. Therefore, the embodiment of the present application can activate one set of transmission resources or multiple sets of transmission resources in the resource group.

In some embodiments, the grouping information may include an offset mode of multiple sets of transmission resources in the group, and the activation information includes an indication of the offset mode of multiple sets of transmission resources in the group. The grouping information can be transmitted through the first instruction signaling or the second instruction instruction. If the offset mode indicated in the first indication signaling or the second indication signaling includes only one type and is unique, the activation information may not need to indicate a specific offset mode. If the offset modes indicated in the first indication signaling or the second indication signaling include multiple types and are not unique, the activation information needs to indicate an offset mode from them. For example, when grouping is performed through RRC signaling or MAC CE signaling, multiple optional offset modes are configured, and then DCI signaling or MAC CE signaling indicates a certain offset mode. If only one offset mode is configured in RRC signaling, neither MAC CE signaling nor DCI signaling may indicate the offset mode. If the offset mode is not configured in RRC signaling, the offset mode can be directly configured through MAC CE signaling or DCI signaling.

In some embodiments, the second indication signaling sent by the base station to the user equipment may further include a modification indication for modifying parameter configuration information. That is, the parameter configuration information of multiple sets of transmission resources is modified through RRC signaling or MAC CE signaling. For example, parameters such as the period of data transmission, power control parameters, and the number of repeated transmissions K. In some scenarios, the RRC signaling configures multiple sets of transmission resources and a combination of multiple sets of transmission resources for the UE, and the activated multiple sets of resources do not match the user's service after a period of time. If RRC signaling is used to reconfigure transmission resources at this time, on the one hand, additional delay will be added, and on the other hand, it will also bring greater signaling overhead. The original RRC signaling configuration can be modified through MAC CE signaling. The parameters can better match the current user’s business. Among them, the modification method may include: in the case of not grouping, modifying one or more parameters of a certain set of transmission resources; in the case of resource grouping or diversity, modifying a certain resource group (a set corresponding to a certain state) Modify one or more parameters of a certain set of transmission resources in a certain resource group (a set corresponding to a certain state), modify one or more parameters of all transmission resources in a certain resource group (a set corresponding to a certain state), modify all resource groups (a set corresponding to a certain state) One or more parameters of a certain set of transmission resources, etc.

In some embodiments, if some parameters of the parameter configuration information configured by RRC signaling are not configured, they can be configured through MAC CE signaling. For example, if multiple sets of transmission resources are configured in RRC signaling but the offset mode between multiple sets of transmission resources in the group is not configured, then the offset configuration method 1 or configuration method 2 described above can be used. The offset mode between multiple sets of transmission resources in the group is configured.

In some embodiments, if the RRC signaling configuration requires more resource status information to be activated, and there are not enough bit fields in the activation signaling to match the status information corresponding to the RRC configuration, you can select from multiple statuses of the RRC configuration through MAC CE Part of the status is indicated to the user, and the activation signaling activates part of the resource status information selected by the MAC CE.

In some embodiments, if the base station sends grouping information to the user equipment through RRC signaling or MAC CE signaling, the grouping information includes at least one resource group. The resource group includes a set of transmission resource parameter configuration information, the number of extended resource sets, and Offset method for extending transmission resources. When the user equipment knows that the resource group includes the information of the number of extended resource sets, it can shift the set of transmission resources in the group bit by bit according to the shift mode of the resource group, until the transmission resources obtained by the expansion in the group The number of sets meets the number of extended resource sets. The parameter configurations of the multiple sets of transmission resources in the expanded resource group are the same, but there is an offset between the transmission resources of different sets.

In some embodiments, the base station sends parameter configuration information of the resource to the user equipment through RRC signaling. The parameter configuration information of each set of resources includes a set identifier, and the parameter configuration information of the resource includes the number of extended resource sets N and the number of extended resource sets.的Offset method. The resource location of the first set of resources is indicated by activation signaling, and the subsequent N-1 sets of resources are respectively offset relative to the first set. The offset configuration may be as described in the offset configuration method 1 described above.

In some embodiments, the base station sends resource parameter configuration information to the user equipment through RRC signaling. The parameter configuration information of each set of resources includes a set of identifiers, and the parameter configuration information of resources includes multiple offset modes. After the signaling is activated, the set of resources are offset according to the multiple indicated offset modes, that is, the configured set of information has multiple starting points of the same or different time/frequency domain resources.

In some embodiments, the base station sends resource parameter configuration information to the user equipment through RRC signaling. The parameter configuration information of each set of resources includes a set identifier, and the parameter configuration information of the resource includes an offset mode and number of offsets. N. After receiving the activation signaling, the user will offset the set of resources according to the aforementioned offset configuration method 2, that is, the configured set of information has N+1 same or different time/frequency domain resources. starting point.

In some embodiments, if the RRC signaling is configured to include multiple sets of transmission resources, but the number of extended resource sets N and the offset mode are not configured, the number of extended resource sets N and the offset mode can be configured through MAC CE signaling, and the user equipment respectively The multiple sets of transmission resources are expanded and expanded into multiple resource groups.

In some embodiments, the configuration information sent to the user equipment may further include state information, and the state information includes multiple states and at least one set of transmission resources or at least one resource group related to each state.

In some embodiments, the state information may also include an offset manner corresponding to each set of transmission resources or sets of resource groups related to the same state, or an offset manner shared by all transmission resources related to the same state.

In some embodiments, the embodiment of the present application may send the status information through the first instruction instruction or the second instruction instruction. One of the implementation manners may be as follows: a first instruction instruction or a second instruction instruction is sent to the user equipment, the first instruction instruction includes parameter configuration information, and the second instruction instruction includes status information. In this way, when sending the activation information of the transmission resource to the user equipment, the activation information may include the status identifier of the transmission resource that needs to be activated. The status identifier is used to activate the transmission resource corresponding to the status identifier. Specifically, the user equipment may use the status identifier to activate the transmission resource related to the status identifier. The transmission resources related to the status identifier may include: one or more sets of transmission resources related to the status identifier, and one or more sets of transmission resources related to the status identifier.

The following describes the resource configuration and activation process related to status information:

The base station can configure multiple sets of transmission resources for the user equipment through RRC signaling, for example: #1, #2, #3, and #4. When configuring multiple sets of transmission resources, the status of each set of resources can also be set, and a set of resources can include one or more states. Or, subsequent RRC signaling or MAC CE signaling may indicate multiple states of the originally configured sets of transmission resources. Similarly, the transmission resource offset mode can be configured through RRC signaling or MAC CE signaling. If RRC signaling does not configure an offset mode for multiple sets of transmission resources, it can be configured through MAC CE signaling.

In combination with the above description, it can be seen that the set in each state includes one or more sets of resources, and each set of resources in the set can correspond to one offset mode or all resources in the set correspond to one offset mode. Wherein, the offset mode corresponding to each set of resources in the set may be the same or different. As shown in Table 5 and Table 6.

table 5

status		Resource allocation 1
0	#1+offset1, #1+offset2, #2+offset1, #2+offset2
1	#2+offset2

2	#3+offset1; #3+offset3
3	...

Table 6

status		Resource allocation 2
0	#1, #2, #3, #4; +offset1
1	#1; +offset1
2	#2;+offset2
3	#3, #4; +offset4

Among them, offset1, offset2, offset3, and offset4 represent offset modes.

In some embodiments, multiple groups of transmission resources are configured for the user equipment through RRC signaling, and each group includes one or more sets of transmission resources, for example: #G1, #G2, #G3, and #G4. The offset mode between resources in the group can be configured or not configured. If the offset mode between resources in the group is not configured, it can be configured through MAC CE signaling. Similar to the above method of setting one or more states for each set of resources, one or more states can also be set for each set of resources. That is, the collection in each state includes at least one resource group. Each group of resources in the set can correspond to one offset mode or all resource groups in the set correspond to one offset mode. Wherein, the offset mode corresponding to each set of resources in the set may be the same or different. See Table 7 and Table 8 below.

Table 7

status		Resource allocation 1
0	#G1+offset1, #G1+offset2, #G2+offset1, #G2+offset2
1	#G2+offset2
2	#G3+offset1, #G3+offset3

0	#G1, #G2, #G3, #G4; +offset1
1	#G1;+offset1
2	#G2;+offset2
3	#G3, #G4; +offset4

In this way, when the RRC signaling configures multiple resource groups for the user equipment, the status of each resource group can also be set through MAC CE signaling to recombine multiple groups of resources. The activation information can use a status identifier, such as status "0", to activate multiple resource groups in the status "0" set, such as #G1, #G2, #G3 and #G4 contained in Table 7 and Table 8 above.
