Description

Scheduling-free resource activation and deactivation method and device, storage medium, base station and user equipment

Technical Field

The invention relates to the field of mobile communication, in particular to a method and a device for activating and deactivating scheduling-free resources, a storage medium, a base station and user equipment.

Background

The 5G New air interface (New Radio, NR) supports two types of uplink scheduling-free transmission modes, and in the scheduling-free transmission mode of type 1, all configuration information is configured by a high-level signaling. A part of configuration information of the type 2 schedule-free transmission Scheme is configured by higher layer signaling, such as frequency hopping, Demodulation Reference Signal (DMRS), Modulation and Demodulation Scheme (MCS) table, total number and period of hybrid automatic Repeat request (HARQ) processes, and so on. Before the UE uses the scheduling-free resource of type 2, the base station needs to activate the resource through Downlink Control Information (DCI), and the user determines the time-frequency resource position of the available resource according to the activated DCI. And when the UE receives the deactivated DCI, the UE cannot continue to use the scheduling-free resource.

The 5G NR downlink non-scheduled transmission follows the Semi-Persistent Scheduling (SPS) mode of LTE, which is similar to the uplink type 2 non-scheduled transmission mode, and the configuration of a part of the downlink SPS resources is configured by a higher layer signaling. Before using the downlink SPS resources, the UE needs to activate the resources through DCI by the base station, where the activated DCI includes information such as time domain resource allocation, frequency domain resource allocation, and MCS index.

Currently, NR only supports one active uplink scheduling-free resource for one serving cell, and downlink only supports one active SPS resource. And when the uplink type 2 scheduling-free resource or the downlink SPS resource is activated, the UE determines the allocated information such as the time-frequency domain resource, MCS and the like according to the activated DCI. The R15LTE supports multiple SPS resources in uplink, and each resource needs to be activated at different time by using different DCI when activated.

At present, when discussing Ultra Reliable and Low Latency Communication (URLLC), NR 16 considers supporting multiple activated uplink scheduling-free resources, and if an LTE method is adopted to activate different resources respectively, the impact on a protocol may be reduced, but because activation and deactivation of each resource require one DCI, the overhead of physical layer signaling is increased.

Detailed Description

As described in the background art, currently, when discussing Ultra Reliable and Low Latency Communication (URLLC), NR 16 considers supporting multiple activated uplink scheduling-free resources, and if an LTE method is adopted to activate different resources respectively, the impact on a protocol may be reduced, but since activation and deactivation of each resource requires one DCI, the overhead of physical layer signaling increases.

In the technical scheme of the invention, the base station can simultaneously activate a plurality of scheduling-free resources by grouping the plurality of scheduling-free resources and indicating the offset, thereby reducing the signaling overhead and improving the communication efficiency between the base station and the user equipment.

It will be understood by those skilled in the art that the symbols referred to in the embodiments of the present invention may be Orthogonal Frequency Division Multiplexing (OFDM) symbols.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

Fig. 1 is a flowchart of a method for scheduling resource activation according to an embodiment of the present invention.

The scheduling-free resource activation method may be used on the base station side, that is, the base station may perform the steps shown in fig. 1.

The method for activating the scheduling-free resource can comprise the following steps:

step S101: dividing the scheduling-free resources into one or more scheduling-free resource groups according to the period of the scheduling-free resources;

step S102: indicating at least a reference resource starting position and a resource length to a user equipment by activating DCI;

step S103: and at least indicating the offset of the time domain starting position of the first available time domain resource of the first scheduling-free resource in the one or more scheduling-free resource groups relative to the reference resource starting position to the user equipment, so that the user equipment determines the first available time domain resource of each scheduling-free resource in the one or more scheduling-free resource groups at least according to the reference resource starting position and the resource length.

It should be noted that the sequence numbers of the steps in this embodiment do not represent a limitation on the execution sequence of the steps.

In the implementation of step S101, the period of the non-scheduling resource included in each non-scheduling resource group is the same, and the periods of the non-scheduling resources included in different non-scheduling resource groups are different.

In this embodiment, when a Hybrid Automatic repeat request (HARQ) process domain and a Redundancy Version (RV) domain in the scheduling DCI are both set to all 0, and the MCS and frequency domain resource allocation domains are set to all 1, the DCI is considered to be a deactivated DCI; when the HARQ process domain and the RV domain in the scheduling DCI are both set to be all 0 and the MCS and frequency domain resource allocation domain are set to be not all 1, the DCI is the active DCI.

When the base station needs to activate the scheduling-free resources, the base station may indicate the starting position of the reference resource and the length of the resource to the user equipment by activating the DCI, and may indicate, to the user equipment in advance, an offset of the time domain starting position of the first available time domain resource of the first scheduling-free resource in the one or more scheduling-free resource groups with respect to the starting position of the reference resource by using a high layer signaling (that is, sending the high layer signaling before sending the activated DCI).

Thus, the base station can activate the scheduling-free resources.

For the user equipment, the user equipment can determine the time domain starting position of the first available time domain resource through the offset and the reference resource starting position; and determining the first available time domain resource (i.e. the time domain position of the first available time domain resource) according to the time domain starting position of the first available time domain resource and the length of the resource.

It is to be appreciated that the schedule-free resources are periodic; after determining the first available time domain resource of the scheduling-free resource, that is, the available time domain resource in the current period, the user equipment may determine the available time domain resource of the scheduling-free resource in other periods according to the period of the scheduling-free resource.

In an embodiment of the present invention, the scheduling-free resource may include a type 2 uplink scheduling-free resource or a downlink SPS scheduling-free resource.

In a non-limiting embodiment 1, for type 2 uplink non-scheduled resource 1 and type 2 uplink non-scheduled resource 2, the periods are 2 slots (slots) and 2 slots, respectively, and the subcarrier spacing (SCS) is 15kHz and 15kHz, respectively.

The base station may divide the scheduling-free resources into one group (e.g., scheduling-free resource group 1). The base station indicates to the UE, by activating DCI, that the reference resource starting position is symbol 3 of the current time slot (i.e., the time slot in which the activated DCI is transmitted) and the resource length is 7 symbols. The base station transmits the activation DCI in slot n.

The base station may determine the number of bits that the identity of the scheduling-free resource group needs to occupy according to the number of the scheduling-free resource groups, for example, the number of bits

And N is the number of the scheduling-free resource groups. The number of bits that need to be occupied for identification of the scheduling-free resource group may also be agreed by a communication standard protocol, for example, the number of bits is 0. Since there is only one scheduling-free resource group, the number of bits that needs to be occupied by the identification of scheduling resource group 1 may be 0. The bit number occupied by the identifier of the scheduling-free resource group can also be configured through high-level signaling, for example, the bit number is 0, and only one scheduling-free resource group can be configured at this time.

When the base station activates the non-scheduling resource group 1, since the number of bits that the identifier of the scheduling resource group 1 needs to occupy is 0, the base station may not need to indicate the identifier of the non-scheduling resource group 1 (that is, 1) in the activation DCI.

The base station may indicate that an offset of a time domain starting position of a first available time domain resource in a scheduling-free resource group 1 (i.e., a type 2 uplink scheduling-free resource 1) from the reference resource starting position is 0. The UE may determine that the time domain starting position of the first available time domain resource is symbol 3 of time slot n, the first available time domain resource is symbols 3-9 of time slot n, and the ith available time domain resource is symbols 3-9 of time slot n +2(i-1), where i is a positive integer. For the first available time domain resource, i ═ 1.

In a preferred embodiment of the present invention, step S101 shown in fig. 1 may include the following steps: and determining the identification of each scheduling-free resource group, wherein at least one scheduling-free resource group comprises two or more scheduling-free resources. Further, in step S102, the base station may indicate, to the user equipment, the identity of the non-scheduling resource group, as well as the reference resource starting position and the resource length, through the activation DCI.

In a non-limiting embodiment 2, for type 2 uplink non-scheduled resource 1, type 2 uplink non-scheduled resource 2, and type 2 uplink non-scheduled resource 3, the periods are 2 slots, and 4 slots, respectively.

Different from the foregoing embodiment 1, the base station may divide the scheduling-free resources into two groups, where the scheduling-free resource group 1 (also identified as 1) includes a type 2 uplink scheduling-free resource 1 and a type 2 uplink scheduling-free resource 2, and the scheduling-free resource group 2 (also identified as 2) includes a type 2 uplink scheduling-free resource 1 and a type 2 uplink scheduling-free resource 3.

And N is the number of the scheduling-free resource groups. The number of bits that need to be occupied for identification of the scheduling-free resource group may also be agreed by a communication standard protocol, for example, the number of bits is 1. Because there are two scheduling resource groups without scheduling, the number of bits that the identifier of the scheduling resource group needs to occupy is 1. The bit number occupied by the identifier of the scheduling-free resource group can also be configured through high-level signaling, for example, the bit number is 1, and at this time, at most two scheduling-free resource groups can be configured.

When activating the non-scheduling resource group 1, the base station may indicate, in the activation DCI, that the identifier of the non-scheduling resource group is 0 to the UE (that is, the bit carried by the activation DCI is 0); when the non-scheduling resource group 2 is activated, the identifier of the non-scheduling resource group may be indicated to be 1 (that is, the bit carried by the activation DCI is 1) in the activation DCI to the UE.

In a preferred embodiment of the present invention, step S103 shown in fig. 1 may include the following steps: and indicating a first offset of a time domain starting position of a first available time domain resource of each available scheduling-free resource in the one or more scheduling-free resource groups relative to a starting position of the reference resource to the user equipment, so that the user equipment determines the time domain starting position of the first available time domain resource of each scheduling-free resource in the scheduling-free resource groups according to the first offset and the starting position of the reference resource.

Specifically, the offset and the first offset are in units of symbols.

In a non-limiting embodiment 3, on the basis of the foregoing embodiment 2, when activating the scheduling-free resource group 1, the base station may indicate the identity of the scheduling-free resource group as 1 to the UE in the activation DCI.

The base station indicates, to the UE, the first offset of the time domain starting position of the first available time domain resource of the type 2 uplink non-scheduling resource 1 and the type 2 uplink non-scheduling resource 2 in the activated non-scheduling resource group 1 relative to the time slot n symbol 3, that is, the first offset of the time domain starting position of the first available time domain resource of the type 2 uplink non-scheduling resource 1 relative to the time slot n symbol 3 is 0 symbol, and the first offset of the time domain starting position of the first available time domain resource of the type 2 uplink non-scheduling resource 2 relative to the time slot n symbol 3 is 14 symbols, respectively through the activated DCI.

Or, the base station may also indicate, to the UE, the first offsets of the type 2 uplink non-scheduling resource 1 and the type 2 uplink non-scheduling resource 2 in the activated non-scheduling resource group 1 in advance through a high-level signaling, that is, the first offset of the type 2 uplink non-scheduling resource 1 is 0 symbol, and the first offset of the type 2 uplink non-scheduling resource 2 is 14 symbols.

The UE can determine that the time domain starting position of the first available time domain resource of the type 2 uplink non-scheduling resource 1 is a symbol 3 of a time slot n, the first available time domain resource is a symbol 3-9 of the time slot n, and the ith available time domain resource is a symbol 3-9 of a time slot n +2 (i-1); the time domain starting position of the first available time domain resource of the type 2 uplink scheduling-free resource 2 is a symbol 3 of a time slot n +1, the first available time domain resource is a symbol 3-9 of the time slot n +1, and the ith available time domain resource is a symbol 3-9 of the time slot n +1+2 (i-1).

In another preferred embodiment of the present invention, step S103 shown in fig. 1 may include the following steps: indicating, to the user equipment, that an offset of a time domain starting position of a first available time domain resource of a first non-scheduled resource in the one or more non-scheduled resource groups from the reference resource starting position is zero; and for a scheduling-free resource group containing two or more scheduling-free resources, sending a second offset between the time domain starting positions of the first available time domain resources of the adjacent scheduling-free resources in the scheduling-free resource group to the user equipment, so that the user equipment determines the time domain starting positions of the first available time domain resources of other scheduling-free resources except the first scheduling-free resources in the scheduling-free resource group according to the second offset and the reference resource starting position.

In a variation of the invention, the base station may also indicate that the offset is a non-zero value. For example, any practicable value such as 1, 2, 4, and 7 (unit is a symbol), which is not limited in the embodiments of the present invention.

In yet another variation of the present invention, the offset may also be agreed upon by a communication standard protocol. Then, the user equipment can directly determine the time domain starting position of the first available time domain resource by using the offset and the reference resource starting position.

It should be noted that available time domain resources of different scheduling-free resources in the same scheduling-free resource group in the same period may overlap. For example, the available time domain resources of non-scheduling resource 1 in time slot n are symbols 3-6, and the available time domain resources of non-scheduling resource 2 in time slot n are symbols 5-8.

In a non-limiting embodiment 4, different from the foregoing embodiment 3, the base station indicates, to the UE through the activation DCI, that an offset of a time domain starting position of a first available time domain resource of a type 2 uplink scheduling-free resource 1 in an activation-free resource group 1 with respect to a slot n symbol 3 is 0; the time domain starting position of the first available time domain resource of the type 2 uplink scheduling-free resource 2 and the time domain starting position of the first available time domain resource of the type 2 uplink scheduling-free resource 1 are shifted by 5 symbols.

Or, the base station may also indicate, to the UE, through a high-level signaling, that the offset of the type 2 uplink non-scheduling resource 1 in the scheduling-free resource group 1 is activated to be 0; the second offset of the type 2 uplink scheduling-free resource 2 is 5 symbols.

The UE can determine that the time domain starting position of the first available time domain resource of the type 2 uplink non-scheduling resource 1 is a symbol 3 of a time slot n, the first available time domain resource is a symbol 3-9 of the time slot n, and the ith available time domain resource is a symbol 3-9 of a time slot n +2 (i-1); the time domain starting position of the first available time domain resource of the type 2 uplink scheduling-free resource 2 is a symbol 8 of a time slot n, the first available time domain resource is a symbol 8-14 of the time slot n, and the ith available time domain resource is a symbol 8-14 of a time slot n +2 (i-1).

In another preferred embodiment of the present invention, step S103 shown in fig. 1 may include the following steps: indicating, to the user equipment, that an offset of a time domain starting position of a first available time domain resource of a first non-scheduled resource in the one or more non-scheduled resource groups from the reference resource starting position is zero; for a scheduling-free resource group containing two or more scheduling-free resources, sending a third offset between a time domain end position of a first available time domain resource of a previous scheduling-free resource and a time domain start position of a first available time domain resource of a next scheduling-free resource in the scheduling-free resource group to the user equipment, so that the user equipment determines time domain start positions of the first available time domain resources of other scheduling-free resources except the first scheduling-free resource in the scheduling-free resource group according to the third offset and the reference resource start position.

In a non-limiting embodiment 5, different from the foregoing embodiment 4, the base station may indicate to the UE that the third offset of the type 2 uplink scheduling-free resource 2 is 2 symbols through the activation DCI or through higher layer signaling in advance.

And the UE receives the activation DCI in the time slot n, the reference resource starting position is the symbol 2 of the time slot n, and the resource length is 5 symbols. The UE can determine that the time domain starting position of the first available time domain resource of the type 2 uplink non-scheduling resource 1 is a symbol 2 of a time slot n, the first available time domain resource is a symbol 2-6 of the time slot n, and the ith available time domain resource is a symbol 2-6 of a time slot n +2 (i-1); the time domain starting position of the first available time domain resource of the type 2 uplink scheduling-free resource 2 is a symbol 9 of a time slot n, the first available time domain resource is a symbol 9-13 of the time slot n, and the ith available time domain resource is a symbol 9-13 of a time slot n +2 (i-1).

In still another preferred embodiment of the present invention, the base station sends a time domain offset identifier to the ue, where the time domain offset identifier is used to indicate the second offset or the third offset.

Specifically, the base station may pre-configure a time domain offset set through higher layer signaling, and the time domain offset set may include one or more time domain offsets. The corresponding relation between each time domain offset and the time domain offset identifier can also be sent to the user equipment in advance through a high-level signaling. In other words, the time domain offset indicated by the time domain offset identifier is the second offset or the third offset.

It should be noted that the time domain offset set and the corresponding relationship between each time domain offset and the time domain offset identifier may also be agreed by a communication standard protocol.

In a non-limiting embodiment 6, different from the foregoing embodiment, the base station configures a time domain offset set {2 symbols, 4 symbols, 7 symbols, 14 symbols } in advance through higher layer signaling, and activates the time domain offset identification field in DCI to be 2 bits. The bit number for activating the time domain offset identification field in the DCI may be agreed by a communication standard protocol, may be sent to the ue through a high-level signaling, or may be determined according to the number of elements in the time domain offset set, for example, the bit number

Wherein M isThe number of elements in the set of time domain offsets. The elements in the time domain offset set configured by the higher layer signaling have a one-to-one correspondence relationship with the values (i.e., codewords) in the time domain offset identification field in the activation DCI, for example, the time domain offset set {2 symbols, 4 symbols, 7 symbols, 14 symbols } corresponds to the values {00,01,10,11} in the time domain offset identification field in the activation DCI, respectively. And the base station indicates the UE that the value of the time domain offset identification field is 00 through the activation DCI so as to indicate 2 symbols. And activating the value in the time domain offset identification field in the DCI to be the time domain offset identification.

The UE can accordingly know that the time domain starting position of the first available time domain resource of the type 2 uplink scheduling-free resource 2 is shifted by 2 symbols from the symbol 3 of the time slot n, that is, the time domain starting position of the first available time domain resource of the type 2 uplink scheduling-free resource 2 is the symbol 5 of the time slot n, the first available time domain resource is the symbol 5-11 of the time slot n, and the ith available time domain resource is the symbol 5-11 of the time slot n +2 (i-1).

Or, the UE may obtain that the time domain starting position of the first available time domain resource of the type 2 uplink scheduling-free resource 2 and the time domain starting position of the first available time domain resource of the type 2 uplink scheduling-free resource 1 are shifted by 2 symbols.

Or, the UE may obtain that the time domain starting position of the first available time domain resource of the type 2 uplink scheduling-free resource 2 and the time domain ending position of the first available time domain resource of the type 2 uplink scheduling-free resource 1 are offset by 2 symbols.

It should be noted that, when the time domain offset set only includes 1 time domain offset, or the communication standard protocol only stipulates 1 time domain offset, the base station may not need to indicate the time domain offset identifier to the UE by activating DCI.

In an embodiment of the present invention, the base station may indicate the identity of the scheduling-free resource group through the NDI and/or reserved bits in the DCI 0-0.

In one non-limiting embodiment 7, the base station may utilize DCI of format DCI0-0 as the activation DCI. The DCI0-0 includes a New Data Indicator (NDI) and a reserved bit. The number of bits of the NDI is 1, and the number of reserved bits is plural.

When the base station uses the DCI with the format of DCI0-0 as the activation DCI, if the identifier of the non-scheduling resource group only occupies one bit, the identifier of the non-scheduling resource group may be indicated by using an NDI or a reserved bit. If the identification of the scheduling-free resource group occupies two bits, the identification of the scheduling-free resource group can be indicated by using the NDI and the first reserved bit, and also can be indicated by using the first and second reserved bits. Similarly, if the identifier of the scheduling-free resource group occupies more than two bits, the identifier of the scheduling-free resource group may be indicated by using the NDI and a plurality of reserved bits, or the identifier of the scheduling-free resource group may be indicated by using only a plurality of reserved bits.

Further, the base station may determine, according to the number of the scheduling-free resource groups, the number of bits that the identities of the scheduling-free resource groups need to occupy, for example, the number of bits

And N is the number of the scheduling-free resource groups. The number of bits that need to be occupied by the identity of the non-scheduling resource group can also be agreed by using a communication standard protocol.

In specific implementation, when the bit number occupied by the identifier of the scheduling-free resource group is calculated by the base station, the base station may send the bit number occupied by the identifier of the scheduling-free resource group to the user equipment through a high-level signaling.

Referring to fig. 2, an embodiment of the present invention further discloses a method for deactivating scheduling-free resources, where the method for deactivating scheduling-free resources may be used at a base station side.

The method for deactivating the scheduling-free resource can comprise the following steps:

step S201: dividing the scheduling-free resources into one or more scheduling-free resource groups according to the period of the scheduling-free resources and determining the identification of each scheduling-free resource group;

step S202: and for indicating the identity of the scheduling-free resource group to the user equipment by deactivating the DCI, indicating that each scheduling-free resource in the scheduling-free resource group is unavailable to the user equipment.

In this embodiment, the base station may deactivate all scheduling-free resources in the scheduling-free resource group indicated by the identifier of the scheduling-free resource group by indicating the identifier of the scheduling-free resource group in the deactivated DCI.

Further, the at least one scheduling-free resource group includes two or more scheduling-free resources. That is to say, when the scheduling-free resource group includes two or more scheduling-free resources, the step S201 and the step S202 may be used to deactivate multiple scheduling-free resources by using the same DCI, so as to avoid that only one scheduling-free resource can be deactivated by using one DCI in the prior art, thereby reducing signaling overhead.
