Description

Method for determining feedback resources, 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 a feedback resource, a user equipment (UE), a network device, and a computer storage medium.

Background technique

The 5G (NR, new radio) system introduces URL-LC (Ultra-reliable low latency xxx), which is characterized by ultra-high reliability (for example, 99.999%) transmission within an extreme delay (for example, 1 ms). In order to achieve this goal, the concept of Grant free was proposed. Grant free adopts the pre-configured and semi-persistent resource configuration mode, and the terminal can transmit on the configured resources according to service requirements. This technology avoids the process of resource request (SR, Schedule Request) and buffer status report (BSR, Buffer Status Report), and increases the effective transmission time of the terminal.

Currently, there are two types of Grant free configuration methods: Type 1 and Type 2. Type 1 uses RRC signaling (semi-static) to configure Grant free resources. Type 2 adopts a combination of RRC and physical layer signaling (semi-static configuration, dynamic activation/deactivation), and RRC signaling configuration. The physical resources transmitted by Grant free 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 K times of repeated transmission is usually employed. However, K times of repeated transmissions may result in redundant transmission. For this reason, an early termination method is introduced, that is, when the data is correctly received by the base station, the base station feeds back an ACK, and terminates the subsequent transmission on the terminal side. Resources for ACK/NACK feedback are not available due to lack of authorization. Therefore, in the Grant Free configuration, the method of determining the ACK/NACK feedback resource needs to be redefined.

Detailed ways

The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Embodiment 1

An embodiment of the present invention provides a method for determining a feedback resource, which is applied to a user equipment (UE), as shown in FIG. 1 , and includes:

Step 101: The UE sends uplink data on a first time slot.

Step 102: Receive downlink control information on the second time slot, and determine feedback information corresponding to the uplink data sent by the first time slot from at least one feedback domain included in the downlink control information.

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

The configuration information sent by the network side is received, where the configuration information includes a relationship between a first time slot in which the UE sends uplink data and a second time slot in which downlink control information is received.

The relationship between the first time slot and the second time slot may be a time relationship between two time slots, and may also be a relationship of other domains, for example, may include a time-frequency resource or the like.

The following is a description of various scenarios:

scene 1,

The method further includes: before determining the feedback information corresponding to the uplink data sent by the first time slot, in the at least one feedback domain that is included in the downlink control information, the method further includes:

Determining a first correspondence between the at least one feedback domain and the uplink data resource; wherein the first correspondence relationship characterizes each feedback domain corresponding to a transmission resource of one uplink data.

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

And determining, according to the first correspondence, the feedback information corresponding to the uplink sent by the first time slot from the at least one feedback domain included in the downlink control information.

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

When the user transmits data on slot n, the user retrieves the PDCCH for ACK/NACK feedback on slot n+k. When the user retrieves the PDCCH, the corresponding domain is read. The PDCCH includes an ACK/NACK feedback field of multiple uplink resources. As shown in FIG. 3, different DMRS CSs have different feedback domains in the downlink control information. In addition, the PDCCH may also include other information related or unrelated to ACK/NACK.

The ACK/NACK feedback domain has a one-to-one correspondence with the uplink resources. The relationship can be a protocol agreement, or configured, or calculated according to certain rules. The uplink resource may be a reference signal resource, and/or a grant free resource sequence number, and/or a frequency domain resource. As shown in FIG. 2, the ACK/NACK feedback field forms a one-to-one relationship with the DMRS sequence in a GRANT FREE resource.

Scene 2

Determining a second correspondence between the at least one feedback domain and the uplink data resource; wherein the second correspondence characterizes each feedback domain to correspond to resources of the at least two uplink data.

That is to say, in this scenario, a feedback field can be used to set feedback information of at least two uplink data. It can also 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 the feedback domain can only feed back to one uplink data resource sent last time.

Determining, according to the second correspondence, a feedback domain corresponding to the uplink sent by the first time slot from at least one feedback domain included in the downlink control information;

And determining, according to the sent uplink data, and the resource information of the at least two uplink data corresponding to the feedback domain, the feedback information corresponding to the uplink data in the feedback domain.

Specifically, unlike scenario 1, one ACK/NACK domain corresponds to multiple DMRS sequences. The method is used when a user configures multiple DMRSs to distinguish the number of transmissions or other uses. The waste of the ACK/NACK domain can be avoided. Because at a time, a user can only send data using a DMRS configuration. For example, as shown in FIG. 4, in the second correspondence, the feedback domain of the uplink data of the DMRS0, 1, and 2 is the corresponding ACK domain in the downlink control information, and the others are also as shown in the figure. Repeatedly.

Scene 3,

Determining a third correspondence between the at least one feedback domain and the uplink data resource; wherein the third correspondence characterizes each feedback domain corresponding to an unlicensed resource and a transmission resource of uplink data. The transmission resource of the uplink data may be one or more of a time domain, a frequency domain, and a code domain.

Determining, according to the third correspondence, 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;

Feedback information for the modulation reference signal and feedback information of an unauthorized resource are obtained from the feedback domain.

Further, the following two processing modes can exist in this scenario:

The processing mode 1 is that the multiple unlicensed resources and the multiple DMRS sequence resources are all corresponding to multiple feedback domains in the same downlink control information. Correspondingly, the UE only needs to extract the feedback information of the corresponding feedback domain according to the preset third correspondence relationship from the same downlink control information.

For example, the uplink resource includes a grant free resource and a DMRS sequence resource. And multiple Grant free resources are fed back in the same downlink control information. The advantage of this method is that multiple grant free resources are put together to feedback, reducing downlink control signaling overhead. For example, as shown in FIG. 5, Grant free 0 is combined with DMRS CS 0 and 6 respectively, corresponding to two feedback domains; and Grant free1 resources can be combined with MDRS CS0 and 6 respectively. Two additional feedback fields.

The processing mode 2 is that the multiple unlicensed resources and the multiple DMRS sequence resources are corresponding to multiple feedback domains in different multiple downlink control information. Correspondingly, the UE also 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 according to the preset third correspondence relationship from the corresponding downlink control information. can.

Specifically, the ACK/NACKs of the multiple grant free resources are respectively mapped in different downlink control signaling. Solve the problem that one downlink control information cannot carry multiple grant free feedback. For example, as shown in FIG. 6, the unlicensed resource grant free0 and the DMRS CS0 and 6 respectively correspond to two feedback domains in the downlink control information 1, and the grant free1 and the DMRS CS0 and 6 respectively correspond to the two feedbacks in the downlink control information 2. area.

Scene 4,

Extracting an uplink time index from the downlink control information;

And detecting, according to the uplink time index, whether the downlink control information includes feedback information of uplink data sent by the first time slot. That is to say, the situation corresponding to the scenario does not indicate the feedback time relationship in advance. Therefore, it is necessary to determine whether the downlink control information includes feedback information according to the uplink time index.

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

This scenario is mainly for the case where there is no feedback timing. In this scenario, the downlink control information needs to include the time domain information of the uplink transmission.

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

For example, when user 1 sends an uplink data in slot n, user 1 detects a downlink control command on slot n+i-n+j, and when the downlink control information is detected in slot n+k, the user reads The PDCCH, where the uplink time index is k, may determine that the PDCCH is feedback on the time slot n according to the current time slot n+k and the uplink index k. Then, according to the correspondence between the uplink physical resource and the ACK/NACK feedback domain, the corresponding ACK/NACK is read. As shown in FIG. 7 , the UE determines the feedback information of the resource for the nth uplink data 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,

Determining the feedback information corresponding to the uplink data sent by the first time slot from the at least one feedback domain included in the downlink control information, including:

Determining, from the at least two uplink time indexes included in the downlink control information, whether each uplink time index is corresponding to a resource for transmitting uplink data in the first time slot;

When the target uplink time index is determined to correspond to the resource of the uplink data sent by the first time slot, the feedback information corresponding to the uplink data is extracted from the feedback domain corresponding to the target uplink time index.

In this scenario, for the case where the downlink control information corresponds to multiple uplink time slot transmissions, the downlink control information needs to indicate multiple uplink time indexes. The difference from the scenario 4 is that one downlink control information includes feedback of multiple uplink time slot transmissions. Therefore, it is necessary to indicate uplink time slot information for each ACK/NACK feedback field. The specific indication method is that an uplink slot domain may be configured before each ACK/NACK domain, or N ACK/NACKs are grouped into one group, and one uplink slot domain is configured. As shown in FIG. 8 , different feedback domains correspond to different time indexes, that is, the UE can directly search for the feedback domain corresponding to the uplink physical resource based on each time index, and no longer needs to be based on the corresponding relationship again. Find the feedback field.

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

It can be seen that, by adopting the foregoing solution, the feedback information corresponding to the uplink data in the downlink control information sent by the first time slot for transmitting the uplink data, the second time slot for receiving the downlink control information, and the second time slot can be obtained. Correspondence to the relationship. In this way, the relationship between the downlink feedback domain that can be directly adopted and the uplink transmission resource is compared with the user, and the downlink feedback overhead is reduced.

Moreover, the processing of the foregoing scheme can also be applied to a scenario in which a plurality of users are multiplexed in a limited physical resource.

Step 901: Receive uplink data sent by the UE on the first time slot.

Step 902: Send downlink control information on the second time slot, where the at least one feedback domain of the downlink control information includes feedback information corresponding to the uplink data sent by the first time slot.

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

The configuration information is sent to the UE, where the configuration information includes a relationship between a first time slot in which the UE sends uplink data and a second time slot in which downlink control information is received.

The following is a description of various scenarios:

scene 1,

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

Correspondingly, the sending the downlink control information on the second time slot includes:

Further, the following two processing modes can exist in this scenario:

Scene 4,

An uplink time index is added to the downlink control information, where the uplink time index indicates feedback information of the uplink data that is sent by the downlink control information for the Nth time slot, where N is an integer.

Sending the downlink control information on the second time slot includes:

When it is determined that the downlink control information is the feedback information of the uplink data that is sent by the first time slot, the corresponding relationship between the resource and the feedback domain based on the preset uplink data is the uplink data of the first time slot. The corresponding feedback field adds feedback information.

Scene 5,

At least two uplink time indexes are added to the downlink control information, and each uplink time index corresponds to a resource of one uplink data.

Sending the downlink control information on the second time slot includes:

When the target uplink time index is determined to correspond to the resource of the uplink data sent by the first time slot, feedback information for the uplink data is added from the feedback domain corresponding to the target uplink time index.

In this scenario, for the case where the downlink control information corresponds to multiple uplink time slot transmissions, the downlink control information needs to indicate multiple uplink time indexes. The difference is that one downlink control information includes feedback of multiple uplink time slot transmissions. Therefore, it is necessary to indicate uplink time slot information for each ACK/NACK feedback field. The specific indication method is that an uplink slot domain may be configured before each ACK/NACK domain, or N ACK/NACKs are grouped into one group, and one uplink slot domain is configured. As shown in FIG. 8 , different feedback domains correspond to different time indexes, that is, the UE can directly search for the feedback domain corresponding to the uplink physical resource based on each time index, and no longer needs to be based on the corresponding relationship again. Find the feedback field.

Moreover, the processing of the foregoing scheme can also be applied to a scenario in which a plurality of users are reused in a limited physical resource.
