Description

Method for determining feedback resource, UE, network device and computer storage medium

Technical Field

The present invention relates to the field of information processing technologies, and in particular, to a method for determining feedback resources, User Equipment (UE), network equipment, and a computer storage medium.

Background

The 5G (NR, new radio) system introduces URLLC (Ultra-reliable low latency xxx), which is characterized by Ultra-high reliability (e.g., 99.999%) transmission within an extreme time delay (e.g., 1 ms). To achieve this goal, the Grant free concept is proposed. The Grant free adopts a resource configuration mode of pre-configuration \ semi-continuous state, and the terminal can transmit on the configured resources according to the service requirement. The technology avoids the processes of resource Request (SR) and Buffer Status Report (BSR), and increases the effective transmission time of the terminal.

At present, there are two types of Grant free configuration, Type1 and Type 2. Wherein, Type1 configures the Grant free resource by using RRC signaling (semi-static). Type2 employs a combined RRC and physical layer signaling method (semi-static configuration, dynamic activation/deactivation), RRC signaling configuration. The physical resources for Grant free transmission are semi-statically configured and do not always match the channel conditions. Therefore, in order to ensure the reliability of data transmission, a method of repeating transmission K times is generally adopted. However, the K times of repeated transmission may cause redundant transmission, and for this reason, an Early termination (Early termination) method is introduced, that is, after data is correctly received by the base station, the base station feeds back an ACK to terminate the subsequent transmission at the terminal side. Due to lack of grant, resources for ACK/NACK feedback cannot be obtained. Therefore, under the Grant Free configuration, a determination method of ACK/NACK feedback resources needs to be redefined.

Detailed Description

So that the manner in which the features and aspects of the embodiments of the present invention can be understood in detail, a more particular description of the embodiments of the invention, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings.

The first embodiment,

An embodiment of the present invention provides a method for determining feedback resources, which is applied to User Equipment (UE), and as shown in fig. 1, the method includes:

step 101: the UE sends uplink data on a first time slot;

step 102: and receiving downlink control information on a second time slot, and determining feedback information corresponding to the uplink data sent by the first time slot from at least one feedback domain contained in the downlink control information.

Here, before the UE transmits uplink data on the first time slot, the method further includes:

receiving configuration information sent by a network side, wherein the configuration information includes a relationship between a first time slot for the UE to send uplink data and a second time slot for receiving downlink control information.

The relationship between the first time slot and the second time slot may be a time relationship between the two time slots, or may also be a relationship between other domains, such as a relationship including time-frequency resources.

The following is described in various scenarios:

scene 1,

Before determining the feedback information corresponding to the uplink data sent by the first timeslot from at least one feedback field included in the downlink control information, the method further includes:

determining a first corresponding relation between at least one feedback domain and uplink data resources; and the first corresponding relation represents that each feedback domain corresponds to the sending resource of one uplink data.

Correspondingly, the determining feedback information corresponding to the uplink data sent by the first timeslot from at least one feedback field included in the downlink control information includes:

and determining feedback information corresponding to an uplink transmitted by the first time slot from at least one feedback domain contained in the downlink control information based on the first corresponding relation.

The base station configures semi-persistent scheduling resources for the user (the semi-persistent scheduling resources include all services of semi-persistent scheduling, at least grant free mode, VOIP service, URLLC service, etc.). Specifically, as shown in fig. 2, the schematic representation in the upper part of the figure indicates to the UE side in advance, and N feedback fields are respectively used for feedback of the corresponding uplink physical resource N; the following schematic representation in the figure is to preset an information header, the information header can be used for setting information related to the UE, different UEs can correspond to different information headers, and the rest of the representation is the same as the schematic representation of the above schematic representation in the figure and is not described again. For example, the base station configures a semi-persistent scheduling resource 1 for a user 1, that is, transmits data on a physical resource block m-m + j on a time slot n +10 × i (the semi-persistent scheduling resource 1 is usually configured as a periodic resource), and a cyclic shift value of a pilot sequence of the base station is 0; the base station configures the same time-frequency resource for users 2-3, but the cyclic shift values of the pilot sequences are 3, 6 and 9 respectively. In addition, the base station instructs the terminal that ACK/NACK feedback for these data occurs in time slot n + k +10 × i. Different users K may be different.

When a user transmits data on slot n, the user retrieves PDCCH for ACK/NACK feedback on slot n + k. And when the user retrieves the PDCCH, reading a corresponding domain. The PDCCH includes multiple ACK/NACK feedback fields of uplink resources, and as shown in fig. 3, different feedback fields are corresponding to downlink control information for different DMRSs CS. In addition, the PDCCH may also contain other information related or unrelated to ACK/NACK.

And the ACK/NACK feedback domain and the uplink resource form a one-to-one corresponding relation. The relationship may be agreed upon by a protocol, or configured, or calculated according to a certain rule. The uplink resource may be a reference signal resource, and/or a grant free resource number, and/or a frequency domain resource. As in fig. 2, the ACK/NACK feedback field forms a one-to-one relationship with a DMRS sequence in one GRANT FREE resource.

Scene 2,

determining a second corresponding relation between at least one feedback domain and uplink data resources; and the second corresponding relation represents that each feedback domain corresponds to at least two uplink data resources.

That is to say, in this scenario, one feedback field can be used to set feedback information of at least two uplink data, and it can be further understood that the at least two uplink data are uplink data sent by the same UE, and then usually one UE does not send too much uplink data at the same time, so that the feedback field can only feed back one uplink data resource sent last time.

determining a feedback domain corresponding to an uplink transmitted by the first time slot from at least one feedback domain contained in the downlink control information based on the second corresponding relation;

and determining feedback information corresponding to the uplink data in the feedback domain based on the transmitted uplink data and the resource information of at least two uplink data corresponding to the feedback domain.

Specifically, unlike scenario 1, one ACK/NACK domain corresponds to multiple DMRS sequences. The method is adopted when one user configures a plurality of DMRSs for distinguishing transmission times or other purposes. Waste of the ACK/NACK field can be avoided. Because one user can only transmit data with one DMRS configuration at one time. For example, as shown in fig. 4, in the preset second correspondence relationship, the feedback domain of the uplink data resource for the

DMRSs

0, 1, and 2 is the corresponding ACK domain in the downlink control information, and the others are also as shown in the figure and are not described again.

Scene 3,

determining a third corresponding relation between at least one feedback domain and uplink data resources; and the third corresponding relation represents that each feedback domain corresponds to an authorization-free resource and a sending resource of uplink data. The uplink data transmission resource may be one or more of a time domain, a frequency domain, and a code domain.

determining a feedback domain corresponding to the modulation reference signal sent by the first time slot from at least one feedback domain included in the downlink control information based on the third corresponding relation;

feedback information for the modulation reference signal and feedback information for unlicensed resources are obtained from the feedback domain.

Further, there may be two following processing modes in this scenario:

the processing method 1 is to correspond multiple license-free resources and multiple DMRS sequence resources to multiple feedback fields in the same downlink control information. Correspondingly, at this time, the UE only needs to extract the feedback information of the corresponding feedback domain from the same downlink control information according to the preset third corresponding relationship.

For example, the uplink resource includes a grant free resource and a DMRS sequence resource. And a plurality of Grant free resources are fed back in the same downlink control information. The method has the advantages that: and a plurality of grant free resources are put together for feedback, so that the downlink control signaling overhead is reduced. For example, as shown in fig. 5, authorization exemption (Grant free)0 is combined with DMRSs CS0 and 6, respectively, and corresponds to two feedback domains; the Grant free1 resource can be further combined with MDRS CS0, 6 respectively to correspond to the other two feedback domains.

And a processing mode 2, wherein the processing mode is to correspond a plurality of authorization-free resources and a plurality of DMRS sequence resources to a plurality of feedback domains in different pieces of downlink control information. Correspondingly, at this time, the UE needs to know in advance which downlink control information the different uplink resources correspond to, and then extract the feedback information of the corresponding feedback domain from the corresponding downlink control information according to the preset third corresponding relationship.

Specifically, the ACKs/NACKs of the grant free resources are mapped in different downlink control signaling respectively. The problem that one downlink control information can not bear feedback of a plurality of grant free is solved. As shown in fig. 6, the unlicensed resources grant free0 and DMRSs CS0, 6 correspond to two feedback domains in downlink control information 1, respectively, and grant free1 and DMRSs CS0, 6 correspond to two feedback domains in downlink control information 2, respectively.

Scene 4,

extracting an uplink time index from the downlink control information;

and detecting whether the downlink control information contains feedback information of the uplink data sent by the first time slot or not based on the uplink time index. That is, the feedback time relationship is not specified in advance in the case of the present scenario, and therefore, it is necessary to determine whether the downlink control information includes the feedback information according to the uplink time index.

when the downlink control information is determined to be feedback information containing the uplink data sent by the first time slot, determining the feedback information corresponding to the uplink data sent by the first time slot based on the corresponding relationship between the preset resource of the uplink data and the feedback domain.

The present scenario mainly aims at the situation that there is no feedback timing, and in this scenario, the downlink control information needs to include time domain information of uplink transmission.

Different from the foregoing scenario, that is, there is no determined feedback timing, and the downlink control information needs to include an uplink time index; in other words, the uplink time index may be understood as time domain information of uplink transmission. The uplink time index, i.e. the time domain information of the uplink transmission, may be characterized as an interval between the uplink transmission and the feedback, a variable related to the interval, or an absolute or relative number of an uplink transmission slot, or an HARQ ID.

For example, when the user 1 sends an uplink data in the time slot n, the user 1 detects the downlink control command in the time slot n + i-n + j, and when the downlink control information is detected in the time slot n + k, the user reads the PDCCH, where the uplink time index is k, and the user can determine that the PDCCH is feeding back to the time slot n according to the current time slot n + k and the uplink index k. And reading corresponding ACK/NACK according to the corresponding relation between the uplink physical resources and the ACK/NACK feedback domain. As shown in fig. 7, the UE determines that the feedback information is feedback information for the nth uplink data resource based on the uplink time index, and reads the feedback information of the corresponding feedback domain according to the correspondence between the feedback domain and the uplink physical resource.

Scene 5,

The determining, from at least one feedback field included in the downlink control information, feedback information corresponding to uplink data transmitted by the first timeslot includes:

sequentially judging whether each uplink time index corresponds to a resource for transmitting uplink data in the first time slot or not from at least two uplink time indexes contained in the downlink control information;

and when determining that the target uplink time index corresponds to the resource of the uplink data sent by the first time slot, extracting feedback information corresponding to the uplink data from a feedback domain corresponding to the target uplink time index.

In this scenario, for the case that the downlink control information corresponds to multiple uplink time slots for transmission, the downlink control information needs to indicate multiple uplink time indices. Different from scenario 4, one piece of downlink control information includes feedback of multiple uplink slot transmissions, and therefore, it is necessary to indicate uplink slot information for each ACK/NACK feedback field. The specific indication method may be that an uplink timeslot domain is configured before each ACK/NACK domain, or that N ACK/NACKs are divided into a group and configured with an uplink timeslot domain. As shown in fig. 8, different feedback domains correspond to different time indexes, that is, the UE may directly find the feedback domain corresponding to the uplink physical resource based on each time index, and does not need to search the feedback domain again according to the corresponding relationship.

Through the analysis of the above multiple scenarios, it can be seen that, in this embodiment, the terminal device receives a downlink control signaling, where the downlink control signaling at least includes at least one domain and corresponds to at least one uplink transmission resource. The terminal equipment detects the downlink control signaling. The physical resource can be one or more of time domain, frequency domain and pilot frequency resource; the correspondence may be 1 to 1, or 1 to many; the downlink control information may further include uplink transmission timeslot information. Of course, it should be understood that the feedback field defined in the present embodiment is not limited to ACK/NACK, and other feedback information, such as MCS, CQI, etc., is also applicable.

Therefore, by adopting the above scheme, the first time slot for sending the uplink data, the second time slot for receiving the downlink control information, and the feedback information corresponding to the uplink data in the downlink control information sent by the second time slot can be correlated with each other. Therefore, the corresponding relation between the downlink feedback domain and the uplink transmission resource can be directly adopted, and compared with the corresponding relation formed between the downlink feedback domain and the uplink transmission resource, the downlink feedback overhead is reduced.

Moreover, the processing of the scheme can be applied to a scene of multiplexing a plurality of users in a limited physical resource.

Example II,

An embodiment of the present invention provides a method for determining feedback resources, which is applied to a network device, and as shown in fig. 9, the method includes:

step 901: receiving uplink data sent by UE on a first time slot;

step 902: and sending downlink control information on a second time slot, wherein at least one feedback domain of the downlink control information contains feedback information corresponding to the uplink data sent by the first time slot.

Here, before the receiving UE transmits uplink data on the first timeslot, the method further includes:

and sending configuration information to the UE, wherein the configuration information comprises a relation between a first time slot for sending uplink data and a second time slot for receiving downlink control information by the UE.

The following is described in various scenarios:

scene 1,

Before the sending the downlink control information on the second timeslot, the method further includes:

Correspondingly, the sending the downlink control information in the second timeslot includes:

and adding feedback information in at least one feedback domain contained in the downlink control information based on the first corresponding relation, wherein the feedback domain corresponds to the uplink transmitted by the first time slot.

Scene 2,

DMRSs

Scene 3,

based on the third corresponding relation, in at least one feedback domain contained in the downlink control information, adding feedback information in a feedback domain corresponding to the modulation reference signal sent by the first time slot; and adding feedback information of the unlicensed resources in the feedback domain.

Further, there may be two following processing modes in this scenario:

Specifically, the ACKs/NACKs of the grant free resources are mapped in different downlink control signaling respectively. The problem that one downlink control information can not bear feedback of a plurality of grant free is solved. For example, as shown in fig. 6, the unlicensed resources grant free0 and DMRSs CS0, 6 respectively correspond to two feedback domains in the downlink control information 1, and the grant free1 and DMRSs CS0, 6 respectively correspond to two feedback domains in the downlink control information 2.

Scene 4,

and adding an uplink time index into the downlink control information, wherein the uplink time index represents feedback information of uplink data sent by the Nth time slot and indicated by the downlink control information, and N is an integer.

The sending of the downlink control information in the second time slot includes:

and when the downlink control information is determined to be feedback information containing the uplink data sent by the first time slot, adding the feedback information in a feedback domain corresponding to the uplink data of the first time slot based on the preset corresponding relationship between the resource of the uplink data and the feedback domain.

Scene 5,

and adding at least two uplink time indexes in the downlink control information, wherein each uplink time index corresponds to one uplink data resource.

and when determining that the target uplink time index corresponds to the resource of the uplink data sent by the first time slot, adding feedback information aiming at the uplink data from a feedback domain corresponding to the target uplink time index.

In this scenario, for the case that the downlink control information corresponds to multiple uplink time slots for transmission, the downlink control information needs to indicate multiple uplink time indices. The difference is that one downlink control information includes feedback for multiple uplink slot transmissions, and therefore, it is necessary to indicate uplink slot information for each ACK/NACK feedback field. The specific indication method may be that an uplink timeslot domain is configured before each ACK/NACK domain, or that N ACK/NACKs are divided into a group and configured with an uplink timeslot domain. As shown in fig. 8, different feedback domains correspond to different time indexes, that is, the UE may directly find the feedback domain corresponding to the uplink physical resource based on each time index, and does not need to search the feedback domain again according to the corresponding relationship.

Example III,

An embodiment of the present invention provides a User Equipment (UE), as shown in fig. 10, including:

a first communication unit 1001, where the UE transmits uplink data on a first timeslot; receiving downlink control information at a second time slot;

the first processing unit 1002 determines feedback information corresponding to uplink data transmitted in the first time slot from at least one feedback field included in the downlink control information.

Here, before the UE transmits uplink data in the first time slot, the first communication unit 1001 receives configuration information transmitted from the network side, where the configuration information includes a relationship between the first time slot in which the UE transmits uplink data and the second time slot in which the UE receives downlink control information.

The following is described in various scenarios:

scene 1,

The first processing unit 1002, before determining, from at least one feedback field included in the downlink control information, feedback information corresponding to uplink data transmitted in the first timeslot, determines a first correspondence between the at least one feedback field and an uplink data resource; and the first corresponding relation represents that each feedback domain corresponds to the sending resource of one uplink data.

Correspondingly, the first processing unit 1002 determines, based on the first corresponding relationship, feedback information corresponding to an uplink transmitted by the first timeslot from at least one feedback field included in the downlink control information.

Scene 2,

The first processing unit 1002 determines a second correspondence between at least one feedback field and an uplink data resource before determining, from the at least one feedback field included in the downlink control information, feedback information corresponding to the uplink data transmitted by the first timeslot; and the second corresponding relation represents that each feedback domain corresponds to at least two uplink data resources.

That is to say, in this scenario, one feedback field can be used to set feedback information of at least two uplink data, and it can be understood that the at least two uplink data are uplink data sent by the same UE, and then at the same time, usually, one UE does not send too much uplink data, so that the feedback field can only feed back one uplink data resource sent last time.

Correspondingly, the first processing unit 1002 determines, based on the second correspondence, a feedback domain corresponding to an uplink transmitted by the first timeslot from at least one feedback domain included in the downlink control information;

DMRSs

Scene 3,

The first processing unit 1002, before determining, from at least one feedback field included in the downlink control information, feedback information corresponding to uplink data transmitted in the first time slot, determines a third correspondence between the at least one feedback field and an uplink data resource; and the third corresponding relation represents that each feedback domain corresponds to an authorization-free resource and a sending resource of uplink data. The uplink data transmission resource may be one or more of a time domain, a frequency domain, and a code domain.

Correspondingly, the first processing unit 1002 determines, based on the third correspondence, a feedback domain corresponding to the modulation reference signal sent by the first timeslot from at least one feedback domain included in the downlink control information;

Further, there may be two following processing modes in this scenario:

Scene 4,

The first processing unit 1002 extracts an uplink time index from the downlink control information before determining feedback information corresponding to uplink data transmitted in the first time slot from at least one feedback field included in the downlink control information; and detecting whether the downlink control information contains feedback information of the uplink data sent by the first time slot or not based on the uplink time index. That is, the feedback time relationship is not specified in advance in the case of the present scenario, and therefore, it is necessary to determine whether the downlink control information includes the feedback information according to the uplink time index.

Correspondingly, when determining that the downlink control information is feedback information including uplink data sent by the first time slot, the first processing unit 1002 determines, based on a correspondence between a preset resource of the uplink data and a feedback field, feedback information corresponding to the uplink data sent by the first time slot.

Scene 5,

The first processing unit 1002 sequentially determines, from at least two uplink time indices included in the downlink control information, whether each uplink time index corresponds to a resource for transmitting uplink data in the first time slot;

Here, before the UE transmits uplink data in the first time slot, the second communication unit 1101 transmits configuration information to the UE, where the configuration information includes a relationship between the first time slot in which the UE transmits uplink data and a second time slot in which downlink control information is received.

Correspondingly, the second processing unit 1102 adds, in at least one feedback domain included in the downlink control information, feedback information in a feedback domain corresponding to the modulation reference signal sent by the first timeslot, based on the third correspondence; and adding feedback information of the unlicensed resources in the feedback domain.

Further, there may be two following processing modes in this scenario:

Scene 4,
