Description

Technical Field

[0001] The present application relates to the field of communications, and in particular to a method for determining transmission resources, a terminal device, and a network device. Background Art

[0002] The current fifth generation (5th generation, 5G) system introduces ultrareliable low latency communication (URLLC), which is characterized by ultra-high reliability (for example, 99.999%) transmission within extreme latency (for example, 1ms). In order to achieve this goal, the concept of grant free is proposed. Grant free can adopt a pre-configured or semi-continuous resource configuration method, and the terminal device can transmit data on the configured resources according to business needs. This technology can avoid the process of schedule request (SR) and buffer status report (BSR), and increase the effective transmission time of the terminal device.

[0003] In order to support flexible uplink and downlink resource configuration, the 5G system uses a semi-static or dynamic method to notify the time slot format. For example, the terminal device receives signaling to obtain slot format related information (SFI) and determines the uplink and downlink time domain resources in each time slot, such as the number and position of time domain symbols.

[0004] In addition, the 5G system also introduces the concept of bandwidth part (BWP). The system bandwidth supported by new radio (NR) is much larger than the maximum 20MHz system bandwidth of long term evolution (LTE). For some terminal devices, due to limited capabilities, they may not be able to support the full system bandwidth. At the same time, in order to improve scheduling efficiency, the concept of bandwidth part BWP is introduced. Within a carrier, the network equipment can configure one or more BWPs for the terminal device, but generally only one BWP is activated at a time, and the activated BWP is used to transmit data.

[0005] Since SFI, BWP and grant free transmission resources are configured independently, the semi-statically configured grant free transmission resources may not be well adapted to the actual transmission resource situation, especially when SFI is dynamically indicated, there will be resource configuration conflicts. Summary of the invention

[0058] Figure 1 FIG. 1 is a schematic flow chart of a method 100 for determining transmission resources according to an embodiment of the present application. The method 100 may be executed by a terminal device. Figure 1 As shown, the method 100 includes: S110, determining at least one first resource within a target time unit, the at least one first resource being used to carry unscheduled data and / or semi-continuously scheduled data; S120, receiving resource information sent by a network device, the resource information being used to indicate resource allocation within the target time unit; S130, determining available resources in the at least one first resource based on the resource information; S140, using the available resources to transmit the unscheduled data and / or semi-continuously scheduled data with the network device.

[0059] In S110, the terminal device determines at least one first resource within the target time unit, which may specifically include: the terminal device receives a configuration signaling sent by a network device, the configuration signaling is used to indicate the at least one first resource. Specifically, the at least one first resource can be used to carry grant free data and / or semi-persistently scheduled data.

[0060] At present, there are two main ways to configure Grant free resources, one of which is to use Radio Resource Control (RRC) signaling (semi-static) to configure the grant free resources, wherein the RRC signaling may include time-frequency domain resources, reference symbol information, modulation and coding methods, and power control parameters. Another method is to use a combination of RRC signaling and physical layer signaling to configure, wherein the RRC signaling configuration includes time domain resource period and power control parameters, and the physical layer signaling configuration includes frequency domain resources, reference symbol information, and modulation and coding methods. Optionally, the at least one first resource can be configured in any of the above two ways, but the embodiments of the present application are not limited to this.

[0061] In an embodiment of the present application, the at least one first resource may be a periodic resource or a non-periodic resource. Specifically, the terminal device determines at least one first resource within a target time unit, each of the at least one first resource may include at least one time domain symbol, and the number of time domain symbols included in each of the at least one first resource may be the same or different.

[0062] For example, Figure 2 As shown, taking the at least one first resource as a periodic resource as an example, the period of the at least one first resource is 4 time domain symbols. Figure 2 , which shows that the at least one first resource includes 7 first resources, 1 to 7 respectively; each first resource includes two time domain symbols, and any two adjacent first resources are separated by two time domain symbols. Among them, 1 to 4 correspond to time slot 1, and 5 to 7 correspond to time slot 2. Here, taking the target time unit as time slot 1 as an example, the at least one first resource includes 4 first resources in the target time unit, namely Figure 2 The first resource 1 to 4 in the Figure 2 In the example, the time domain symbol may be an orthogonal frequency division multiplexing (OFDM) symbol.

[0063] Optionally, the at least one first resource may be an uplink resource or a downlink resource, that is, the first resource may be used to transmit uplink data or downlink data, but the embodiments of the present application are not limited thereto.

[0064] In S120, the terminal device receives resource information sent by the network device, and the resource information is used to indicate resource allocation in the target time unit. Optionally, the resource information can be used to indicate at least one BWP, and / or the resource information can also be used to indicate the time slot format of the target time unit.

[0065] Specifically, the terminal device may receive a configuration signaling sent by a network device, where the configuration signaling is used to carry the resource information. For example, the configuration signaling may be an RRC signaling, but the embodiments of the present application are not limited thereto.

[0066] Optionally, the resource information can be used to indicate at least one BWP. The network device can configure one or more BWPs for the terminal device, and usually, the terminal device only activates one BWP at a time. The resource information can be used to indicate the activated BWP. Optionally, the resource information can also be used to indicate other BWPs. The embodiments of the present application are not limited to this. Specifically, any BWP indicated by the resource information may include three parameters: a basic parameter set (Numerology), a center frequency, and a bandwidth, where Numerology represents a basic parameter set and can represent a subcarrier spacing (SCS); the bandwidth is less than or equal to the maximum system bandwidth.

[0067] Optionally, the resource information may also be used to indicate a time slot format of a target time unit, wherein the time slot format may include the position and number of time domain symbols included in the target time unit.

[0068] In an embodiment of the present application, the terminal device can determine the resource allocation situation of the terminal device based on the resource information, and the resource allocation situation includes the BWP and time slot format of the terminal device, and then determine at least one second resource within the target time unit allocated by the network device to the terminal device. The at least one second resource can be an uplink resource or a downlink resource, so that the terminal device can use the at least one second resource to transmit data with the network device.

[0069] In S130, the terminal device determines available resources in the at least one first resource based on the resource information. Specifically, the terminal device can determine at least one second resource corresponding to the resource information within the target time unit, and then determine the target characteristics of the at least one second resource and the target characteristics of the at least one first resource. When the target characteristics of the at least one first resource are the same as those of the at least one second resource, the terminal device determines at least one overlapping resource of the at least one first resource and the at least one second resource, and determines available resources in the at least one overlapping resource. Optionally, the terminal device can determine whether a target overlapping resource in the at least one overlapping resource is an available resource based on a preset condition, wherein the target overlapping resource can be any one of the at least one overlapping resource.

[0070] It should be understood that the target feature may include at least one of a transmission direction, a subcarrier spacing, and a cyclic prefix length. The transmission direction is that the at least one first resource and the at least one second resource are both used for uplink transmission or both used for downlink transmission.

[0071] Optionally, as an embodiment, within a target time unit, each of at least one overlapping resource may include at least one time domain symbol, and correspondingly, a preset condition for the terminal device to determine whether a target overlapping resource among the at least one overlapping resource is an available resource may include: when the number of time domain symbols included in the target overlapping resource is greater than or equal to a preset value, the target overlapping resource may be determined as an available resource.

[0072] It should be understood that the preset value in the above preset condition can be set according to actual conditions. Optionally, the preset value can be pre-configured by the network device, specifically, the terminal device receives configuration information sent by the network device, the configuration information is used to indicate the preset value, and the terminal device determines the preset value according to the configuration information.

[0073] Optionally, the preset value can also be determined by the terminal device according to the number of time domain symbols included in one of the at least one first resources. Specifically, the number of time domain symbols included in the at least one first resource can be the same, then the preset value can be equal to the number of time domain symbols included in each of the at least one first resource. The time domain symbols included in the at least one first resource can also be different, then the preset value can be equal to the maximum value or minimum value therein, the maximum value refers to the number of time domain symbols included in the first resource with the most time domain symbols in the at least one first resource, and the minimum value refers to the number of time domain symbols included in the first resource with the least time domain symbols in the at least one first resource; or, the preset value can also be equal to the number of time domain symbols included in the first resource corresponding to the target overlapping resource.

[0074] For example, Figure 2 As shown, it is assumed that the target time unit includes time slot 1 and time slot 2, and each time slot includes 14 time domain symbols, and OFDM symbols are taken as an example here; in addition, Figure 2The figure also shows 7 first resources included in at least one first resource in the target time unit, which are numbered 1 to 7 respectively, and two second resources are included in the target time unit, which are numbered 1 and 2 respectively, wherein the 7 first resources and the two second resources are all used for uplink transmission, that is, they are all uplink resources, and the preset condition is set to: if the time domain symbol included in the target overlapping resource among the multiple overlapping resources of the 7 first resources and the 2 second resources is greater than or equal to the preset value, the target overlapping resource is determined as an available resource. Optionally, it is assumed here that each of the 7 first resources includes the same number of time domain symbols, for example, each first resource includes two OFDM symbols, then the preset value in the preset condition can be equal to the number of time domain symbols included in each first resource, that is, the preset value is equal to two OFDM symbols. Taking the first resource 3 as an example, the overlapping part of the first resource 3 and the two second resources is the target overlapping resource, and the number of time domain symbols included in the target overlapping resource is equal to two OFDM symbols, so the target overlapping resource can be determined as an available resource. Taking the first resource 5 as an example, the overlapping part of the first resource 5 and the two second resources is the target overlapping resource, and the number of time domain symbols included in the target overlapping resource is less than two OFDM symbols, so the target overlapping resource does not belong to the available resources. By analogy, the resources determined as available resources among the overlapping resources of the 7 first resources and the 2 second resources are the resources corresponding to the first resources 2, 3, 4, 6 and 7.

[0075] For example, still Figure 2 For example, assuming that the time domain symbols included in the 7 first resources here are different, the preset value can also be set to the maximum or minimum value of the number of time domain symbols included in the at least one first resource, or the preset value can also be set to the size of the first resource corresponding to the target overlapping resource. Taking the first resource 5 as an example, the overlapping part of the first resource 5 and the two resources is the target overlapping resource. Since the target overlapping resource is only a part of the first resource 5, that is, the number of time domain symbols included in the target overlapping resource is less than the number of time domain symbols included in the first resource 5, the target overlapping resource corresponding to a part of the first resource 5 does not belong to the available resources.

[0076] Optionally, as an embodiment, within the target time unit, at least one first resource includes resources occupied by a reference signal, and correspondingly, at least one overlapping resource may also include resources occupied by a reference signal. Correspondingly, the preset condition for the terminal device to determine whether the target overlapping resource in the at least one overlapping resource is an available resource may include: if the target overlapping resource in the at least one overlapping resource includes resources occupied by a reference signal, and the reference signal is part or all of the reference signal corresponding to the target antenna port, then the target overlapping resource is determined as an available resource, and the target antenna port is an antenna port among the at least one antenna ports used to transmit the unscheduled data and / or semi-continuously scheduled data.

[0077] It should be understood that if the target overlapping resources include resources occupied by a reference signal, and the reference signal is a partial signal in the reference signal corresponding to the target antenna port, the partial signal can also complete channel estimation.

[0078] For example, Figure 3 As shown, it is assumed that the target time unit includes time slot 1 and time slot 2, and each time slot includes 14 time domain symbols, and OFDM symbols are taken as an example here; in addition, Figure 3 It shows 7 first resources included in at least one first resource in the target time unit, which are numbered 1 to 7 respectively, and two second resources are included in the target time unit, which are numbered 1 and 2 respectively, wherein the 7 first resources and the two second resources are all used for uplink transmission, that is, they are all uplink resources, and the 7 first resources all include resources occupied by reference signals, that is, the part shown in the black box in each first resource. Here, the preset condition is set as: if the target overlapping resource among the multiple overlapping resources of the 7 first resources and the 2 second resources includes a reference signal, and the reference signal is all the reference signals in the reference signal corresponding to the target antenna port, then the target overlapping signal is determined as an available resource.

[0079] Optionally, Figure 3 Taking the first resource 2 in as an example, the overlapping part of the first resource 2 and the two second resources includes the entire first resource 2, that is, the target overlapping resource is the entire first resource 2, including the resources occupied by all reference signals in the first resource 2. Therefore, according to the preset rules, the target overlapping resource corresponding to the first resource 2 can be determined as an available resource.

[0080] Optionally, Figure 3Taking the first resource 4 in as an example, the overlapping part of the first resource 4 and the two second resources only includes the left half of the first resource 4, that is, the target overlapping resource is the left half of the first resource 4, but includes the resources occupied by all reference signals in the first resource 4. Therefore, according to the preset rules, the target overlapping resource corresponding to the first resource 4 can be determined as an available resource, that is, the available resource is only the left half of the first resource 4.

[0081] Optionally, Figure 3 Taking the first resource 5 in as an example, the overlapping part of the first resource 5 and the two second resources only includes the right half of the first resource 5, that is, the target overlapping resource is the right half of the first resource 5, but does not include the resources occupied by all reference signals in the first resource 5. Therefore, according to the preset rules, the target overlapping resource corresponding to the first resource 5 can be determined as not belonging to the available resources, that is, the available resources do not include the first resource 5.

[0082] Therefore, if Figure 3 As shown, according to the above preset rules, the available resources can be determined as follows Figure 3 As shown, each available resource includes resources occupied by reference signals, and the reference signals are all reference signals of the corresponding antenna ports.

[0083] For example, Figure 4 As shown, it is assumed that the target time unit includes time slot 1, which includes 14 time domain symbols. Here, OFDM symbols are taken as an example; in addition, it is assumed that the terminal device only activates one BWP, that is, Figure 4 As shown, a second resource numbered 1 can be determined according to the target time unit and the BWP; and Figure 4 Four first resources included in at least one first resource within the target time unit are shown, numbered 1 to 4 respectively, wherein the four first resources and one second resource are all used for uplink transmission, that is, they are all uplink resources, and the four first resources all include resources occupied by reference signals, that is, the part shown in the black box in each first resource. Here, the preset condition is set as: if the target overlapping resource among the multiple overlapping resources of the four first resources and one second resource includes a reference signal, and the reference signal is all or part of the reference signal in the reference signal corresponding to the target antenna port, then the target overlapping signal is determined as an available resource.

[0084] Optionally, Figure 4 Taking the first resource 1 in as an example, there are no overlapping resources between the first resource 1 and the second resource, so there are no available resources in the first resource 1.

[0085] Optionally, Figure 4Taking the first resource 3 in as an example, the overlapping resources between the first resource 3 and the second resource are the lower half of the first resource 3, that is, the target overlapping resources corresponding to the first resource 3 are the lower half of the first resource 3. Since the target overlapping resources include resources occupied by the reference signal, and the reference signal is a partial reference signal in the corresponding first resource 3, according to the preset rules, the target overlapping resources corresponding to the first resource 3 can be determined as available resources.

[0086] By analogy, the Figure 4 Among the four first resources, the lower parts of the first resources 2, 3 and 4 can all be determined as available resources. It should be understood that for the available resources that only include resources occupied by part of the reference signals, the part of the reference signals can also independently complete channel estimation.

[0087] Optionally, as an embodiment, if at least one first resource includes a first sub-resource and a second sub-resource, and the first sub-resource and the second sub-resource are adjacent in the time domain or the frequency domain, the first sub-resource includes resources occupied by a first reference signal, and the second sub-resource includes resources occupied by a second reference signal, the preset condition may include: if the first target overlapping resource does not include or includes part of the resources occupied by the first reference signal, and the second target overlapping resource includes all or part of the resources occupied by the second reference signal, then the first target overlapping resource and the second target overlapping resource are both determined as available resources, wherein the first target overlapping resource is the overlapping resource of the first sub-resource and the at least one second resource, and the second target overlapping resource is the overlapping resource of the second sub-resource and the at least one second resource.

[0088] It should be understood that if the first target overlapping resources do not include the resources occupied by the first reference signal at all, and the second target overlapping resources include all or part of the resources occupied by the second reference signal, correspondingly, the second reference signal is used to estimate the channel corresponding to the first target overlapping resources and / or the channel corresponding to the second target overlapping resources.

[0089] It should be understood that if the first target overlapping resources include part of the resources occupied by the first reference signal, and the second target overlapping resources include part of the resources occupied by the second reference signal, the first reference signal and the second reference signal are used to jointly estimate the channel corresponding to the first target overlapping resources and / or the channel corresponding to the second target overlapping resources.

[0090] For example, Figure 5 As shown, it is assumed that the target time unit includes time slot 1, and the time slot 1 includes 14 time domain symbols, and OFDM symbols are taken as an example here; in addition, Figure 4It shows 7 first resources included in at least one first resource in the target time unit, which are numbered 1 to 7 respectively, and the 7 first resources are continuous in the time domain; the target time unit also includes a second resource, wherein the 7 first resources and 1 second resource are all used for uplink transmission, that is, they are all uplink resources, and the 7 first resources all include resources occupied by reference signals, that is, the part shown by the black box in each first resource.

[0091] Specifically, Figure 5 As shown, the overlapping resources of the first resource 2 and the second resource among the 7 first resources do not include resources occupied by the reference signal, that is, the first resource 2 can be a first sub-resource, and the overlapping resources of the first resource 2 and the second resource are the first target overlapping resources, and the first target overlapping resources do not include resources occupied by the reference signal. The overlapping resources of the first resource 3 adjacent to the first resource 2 among the 7 first resources and the second resource include resources occupied by the reference signal, and include resources occupied by all corresponding reference signals, that is, the first resource 3 can be a second sub-resource, and the overlapping resources of the first resource 3 and the second resource are the second target overlapping resources, and the second target overlapping resources are all of the first resource 3, then the second target overlapping resources include resources occupied by all reference signals in the first resource 3. Therefore, according to the above preset conditions, the first target overlapping resources and the second target overlapping resources can be determined as available resources. Among them, since the first target overlapping resources and the second target overlapping resources are adjacent in the time domain, the reference signal carried in the second target overlapping resources can be used to perform channel estimation on the signal carried in the first target overlapping resources and the signal carried in the second target overlapping resources.

[0092] In an embodiment of the present application, the terminal device determines available resources in the first resource in the above manner, and then in S140, uses the available resources to transmit the unscheduled data and / or semi-continuously scheduled data with the network device.

[0093] Specifically, if the available resources are uplink resources, the terminal device determines the available resources in the above manner, and sends the unscheduled data and / or semi-continuously scheduled data to the network device through the available resources. Similarly, the network device can determine the available resources so as to receive the unscheduled data and / or semi-continuously scheduled data sent by the terminal device through the available resources. If the available resources are downlink resources, the terminal device determines the available resources in the above manner, and receives the unscheduled data and / or semi-continuously scheduled data sent by the network device through the available resources. Similarly, the network device can determine the available resources so as to send the unscheduled data and / or semi-continuously scheduled data to the terminal device through the available resources.

[0094] Therefore, in the method for determining transmission resources in an embodiment of the present application, the terminal device determines available resources from at least one first resource for transmitting unscheduled data and / or semi-continuously scheduled data within a target time unit through the resources configured by the network device, and uses the available resources to transmit the unscheduled data and / or semi-continuously scheduled data. This can make the semi-statically configured unscheduled transmission resources better adapt to the actual transmission resource situation, especially for the situation of dynamically indicating time domain and frequency domain resource allocation, thereby avoiding resource configuration conflicts.

[0095] Combined with the above Figures 1 to 5 , describes in detail the method for determining transmission resources according to an embodiment of the present application from the perspective of a terminal device, and will now be combined with Figure 6 , describes the method for determining transmission resources according to an embodiment of the present application from the perspective of a network device.
