Description

Method and device for activating and deactivating scheduling-free resources, storage medium, base station and user equipment

Technical Field

The present invention relates to the field of mobile communications, and in particular, to a method and apparatus for activating and deactivating a scheduling-free resource, a storage medium, a base station, and a user equipment.

Background

The 5G New air interface (NR) supports two types of uplink scheduling-free transmission modes, and in the type 1 scheduling-free transmission mode, all configuration information is configured by high-level signaling. A part of configuration information of the type 2 non-scheduled transmission mode is configured by higher layer signaling, such as frequency hopping, demodulation reference signals (Demodulation Reference Signal, DMRS), modulation and demodulation mode (Modulation and Coding Scheme, MCS) table, hybrid automatic repeat request (Hybrid Automatic Repeat request, HARQ) process total number and period, and the like. Before the UE uses the scheduling-free resource of type 2, the base station is required to activate the resource through downlink control information (Downlink Control Information, DCI), and the user determines the time-frequency resource location of the available resource according to the activated DCI. The UE cannot continue to use the scheduling-free resource after receiving the deactivated DCI.

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

At present, NR only supports one activated uplink scheduling-free resource for one service cell, and only supports one activated SPS resource for the downlink. When the uplink type 2 scheduling-free resource or the downlink SPS resource is activated, the UE determines the allocated time-frequency domain resource, MCS and other information according to the activated DCI. R15LTE supports multiple uplink SPS resources, each of which, when activated, needs to be activated at a different time using a different DCI.

At present, NR R16 considers supporting a plurality of activated uplink scheduling-free resources when discussing Ultra Reliable and low-delay communication (URLLC), if different resources are activated respectively in an LTE manner, the influence on a protocol can be reduced, but since activation and deactivation of each resource requires one DCI, the overhead of physical layer signaling is increased.

Detailed Description

As described in the background art, at present, NR R16 considers supporting multiple activated uplink scheduling-free resources when discussing Ultra Reliable and low-delay communication (URLLC), if different resources are activated by LTE, the influence on the protocol can be reduced, but since each resource needs one DCI for activation and deactivation, the overhead of physical layer signaling increases.

In the technical scheme of the invention, the base station groups the plurality of scheduling-free resources and can activate the plurality of scheduling-free resources simultaneously by indicating the offset, so that the signaling overhead can be reduced and the communication efficiency between the base station and the user equipment can be improved.

It will be appreciated by those skilled in the art that the symbols referred to in embodiments of the present invention may be orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbols.

In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.

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

The method for activating the scheduling-free resource can be used at the base station side, that is, the base station can 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 user equipment by activating DCI;

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

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

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

In this embodiment, when the hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) process domain and redundancy version (Redundancy Version, RV) domain in the scheduling DCI are both set to all 0, and the mcs and frequency domain resource allocation domain are set to all 1, then the DCI is considered to be the deactivation DCI; when both the HARQ process field and the RV field in the scheduling DCI are set to all 0, and the mcs and frequency domain resource allocation field are set to not all 1, then the DCI is an active DCI.

When the base station needs to activate the non-scheduling resources, a reference resource starting position and a resource length can be indicated to the user equipment through activating DCI, and an offset of a time domain starting position of a first available time domain resource of a first non-scheduling resource in the one or more non-scheduling resource groups relative to the reference resource starting position can be indicated to the user equipment in advance through higher layer signaling (i.e., the higher layer signaling is sent before the activating DCI is sent).

So far, the base station can activate the scheduling-free resource.

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) by the time domain starting position of the first available time domain resource and the resource length.

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

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

In one 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 (slot), 2 slots, respectively, and the subcarrier spacings (subcarrier spacing, SCS) are 15kHz, respectively.

The base station may divide the non-scheduled resources into a group (e.g., non-scheduled resource group 1). The base station indicates to the UE through the active DCI that the reference resource start position is symbol 3 of the current slot (i.e., the slot in which the active DCI is transmitted) and the resource length is 7 symbols. The base station transmits the activation DCI in slot n.

The base station can determine the number of bits needed to be occupied by the identification of the free-scheduling resource group based on the number of free-scheduling resource groups, e.g. the number of bits

Wherein N is the number of the scheduling-free resource groups. The number of bits that need to be occupied by the identification of the scheduling-free resource group can also be agreed by using a communication standard protocol, for example, the number of bits is 0. Since there is only one non-scheduled resource group, the number of bits that the identification of scheduled resource group 1 needs to occupy may be 0. The number of bits that need to be occupied by the identification of the non-scheduling resource group may also be configured through higher layer signaling, for example, the number of bits is 0, where only one non-scheduling resource group can be configured.

When the base station activates the no-scheduling resource group 1, since the number of bits that the identification of the scheduling resource group 1 needs to occupy is 0, the base station may not need to indicate the identification of the no-scheduling resource group 1 (i.e. 1) in the activation DCI.

The base station may indicate that the offset of the time domain starting position of the first available time domain resource in the first non-scheduling resource in the non-scheduling resource group 1 (i.e. the type 2 uplink non-scheduling resource 1) with respect to 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 slot n, the first available time domain resource is symbol 3-9 of slot n, and the i-th available time domain resource is symbol 3-9 of 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: an identification of each non-scheduling resource group is determined, at least one non-scheduling resource group comprising two or more non-scheduling resources. Further in step S102, the base station may indicate to the user equipment the identification of the scheduling-free resource group, the reference resource start position and the resource length through the active DCI.

In one 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.

Unlike the foregoing embodiment 1, the base station may divide the foregoing non-scheduled resources into two groups, where the non-scheduled resource group 1 (i.e., identified as 1) includes the type 2 uplink non-scheduled resource 1 and the type 2 uplink non-scheduled resource 2, and the non-scheduled resource group 2 (i.e., identified as 2) includes the type 2 uplink non-scheduled resource 1 and the type 2 uplink non-scheduled resource 3.

Wherein N is the number of the scheduling-free resource groups. The number of bits that need to be occupied by the identification of the scheduling-free resource group can also be agreed by using a communication standard protocol, for example, the number of bits is 1. Since there are two scheduling-free resource groups, the number of bits that the identification of the scheduling resource group needs to occupy is 1. The number of bits that need to be occupied by the identification of the non-scheduling resource group may also be configured through higher layer signaling, for example, the number of bits is 1, and at the same time, at most two non-scheduling resource groups may be configured.

When activating the scheduling-free resource group 1, the base station can indicate that the identifier of the scheduling-free resource group is 0 to the UE in the activated DCI (i.e., the bit carried by the activated DCI is 0); when the no-scheduling resource group 2 is activated, an identification of the no-scheduling resource group may be indicated to the UE in the activation DCI as 1 (i.e., the bit carried by the activation DCI is 1).

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 the reference resource starting position 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 reference resource starting position.

Specifically, the unit of the offset and the first offset is a symbol.

In a non-limiting embodiment 3, based on the foregoing embodiment 2, the base station may indicate, to the UE in the activation DCI, that the identification of the no-scheduling resource group is 1 when activating the no-scheduling resource group 1.

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

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

The UE can determine that the time domain initial position of the first available time domain resource of the type 2 uplink scheduling-free resource 1 is the symbol 3 of the time slot n, the first available time domain resource is the symbol 3-9 of the time slot n, and the ith available time domain resource is the symbol 3-9 of the 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 the symbol 3 of the time slot n+1, the first available time domain resource is the symbol 3-9 of the time slot n+1, and the ith available time domain resource is the 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 the offset between 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 and 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 time domain starting positions of first available time domain resources of 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 positions.

In a variation of the present invention, the base station may also indicate that the offset is a non-zero value. For example, 1, 2, 4, 7 (in symbols), etc., and embodiments of the present invention are not limited in this regard.

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

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

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

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

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

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

In one non-limiting embodiment 5, unlike the foregoing embodiment 4, the base station may indicate to the UE that the third offset of the type 2 uplink non-scheduled resource 2 is 2 symbols through the active DCI or through higher layer signaling in advance.

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

In a further preferred embodiment of the present invention, the base station transmits a time domain offset identifier to the user equipment, 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, which may contain one or more time domain offsets, through higher layer signaling. 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 the higher layer 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 corresponding relationship between 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 one non-limiting embodiment 6, unlike the previous embodiments, the base station configures a time domain offset set {2 symbols, 4 symbols, 7 symbols, 14 symbols } in advance through higher layer signaling, activating the time domain offset identification field in the DCI to be 2 bits. The number of bits activating the time domain offset identification field in the DCI may be agreed by a communication standard protocol, may be sent to the ue by higher layer signaling, or may be determined according to the number of elements in the time domain offset set, e.g. the number of bits

Where M is the number of elements in the time domain offset set. The higher layer signaling configures elements in the time domain offset set to have a one-to-one correspondence with values (i.e., codewords) in the time domain offset identification field in the active DCI, e.g., {2 symbols, 4Symbols, 7 symbols, 14 symbols, correspond to the values {00,01,10,11} of the time domain offset identification field in the active DCI, respectively. The base station indicates to the UE that the value of the time domain offset identification field is 00 through the active DCI to indicate 2 symbols. Wherein, the value in the time domain offset identification field in the activated DCI is the time domain offset identification.

The UE may acquire that the time domain starting position of the first available time domain resource of the type 2 uplink non-scheduling resource 2 is offset from the symbol 3 of the time slot n by 2 symbols, that is, the time domain starting position of the first available time domain resource of the type 2 uplink non-scheduling 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 learn that the time domain starting position of the first available time domain resource of the type 2 uplink non-scheduling resource 2 is offset from the time domain starting position of the first available time domain resource of the type 2 uplink non-scheduling resource 1 by 2 symbols according to the time domain starting position.

Or, the UE may learn that the time domain starting position of the first available time domain resource of the type 2 uplink non-scheduling resource 2 is offset from the time domain ending position of the first available time domain resource of the type 2 uplink non-scheduling resource 1 by 2 symbols according to the above.

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

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

In one non-limiting embodiment 7, the base station may utilize DCI in the format DCI0-0 as the activation DCI. DCI0-0 contains a new data indication (New Data Indicator, NDI) and reserved bits. The number of bits of NDI is 1, and there are a plurality of reserved bits.

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

Further, the base station may determine the number of bits that need to be occupied by the identification of the no-dispatch resource group according to the number of no-dispatch resource groups, e.g. the number of bits

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

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

Referring to fig. 2, the embodiment of the invention also discloses a method for deactivating the scheduling-free resource, which can be used at the base station side.

The method for deactivating the scheduling-free resource may comprise the steps of:

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

step S202: and for indicating the identification of the non-scheduling resource group to the user equipment through deactivation of DCI, so as to indicate the unavailability of each non-scheduling resource in the non-scheduling resource group to the user equipment.

In this embodiment, the base station may implement deactivation of all the non-scheduling resources in the non-scheduling resource group indicated by the identifier of the non-scheduling resource group by indicating the identifier of the non-scheduling resource group in the deactivation DCI.

Further, the at least one schedule-free resource group includes two or more schedule-free resources. That is, when the scheduling-free resource group includes two or more scheduling-free resources, the same deactivation DCI can be used to deactivate a plurality of scheduling-free resources through the above step S201 and step S202, which avoids that one deactivation DCI can only deactivate one scheduling-free resource in the prior art, thereby reducing signaling overhead.

For more specific implementation of the embodiments of the present invention, please refer to the foregoing embodiments, and the description thereof is omitted herein.

Referring to fig. 3, the embodiment of the invention also discloses a method for activating the scheduling-free resource, which can be used for the user equipment side.

step S301: determining one or more scheduling-free resource groups, wherein the one or more scheduling-free resource groups are obtained by dividing a plurality of scheduling-free resources according to the period of the scheduling-free resources by a base station;

step S302: receiving an activation DCI;

step S303: determining at least a reference resource starting position and a resource length according to the activated DCI;

step S304: determining an offset of a time domain starting position of a first available time domain resource of a first scheduling-free resource in the one or more scheduling-free resource groups relative to the reference resource starting position;

step S305: and determining the first available time domain resource of each non-scheduling resource in the one or more non-scheduling resource groups at least according to the reference resource starting position and the resource length.

In a specific implementation, when determining the scheduling-free resources included in the one or more scheduling-free resource groups, the UE may be determined through higher layer signaling sent by the base station.

In one non-limiting embodiment of the present invention, the reference resource start position and the offset may be transmitted by a base station to a UE. For example, the base station indicates the reference resource start position by activating DCI, and the base station indicates the offset by higher layer signaling.

In a variation of the present invention, the reference resource starting position and the offset may be predefined by a communication standard protocol. Then, the user equipment may directly determine a time domain starting position of the first available time domain resource by using 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) by the time domain starting position of the first available time domain resource and the resource length.
