This application claims the priority of the Chinese patent application filed with the China Patent Office on January 15, 2021, the application number is 202110057753.6, and the invention name is "PUCCH retransmission determination, configuration method and device, storage medium, user equipment, network side equipment" , the entire contents of which are incorporated herein by reference.

Background technique

In the discussion on the coverage enhancement of the communication protocol version 17 (Release17, R17), the physical uplink control channel (Physical Uplink Control Channel, PUCCH) needs to increase the number of retransmissions to improve the coverage capability.

When a user equipment (User Equipment, UE) sends PUCCH, it can be divided into the following two cases: Case-1: UE does not have dedicated PUCCH resource configuration information; Case-2: UE has dedicated PUCCH resource configuration information. Among them, in case-1, the UE obtains the relevant configuration information of the PUCCH in the system information block (System Information Block, SIB) 1. After the UE determines the row index (index), it can know a series of configuration information corresponding to the specific PUCCH. The row index is jointly determined according to the sequence number of the first control channel element (Control Channel Element, CCE) of the PDCCH and the PUCCH resource (resource) indication information in the downlink control information (Downlink Control Information, DCI). Among them, the PUCCH of Case-1 has no number of retransmissions, that is, it is only transmitted once. In Case-2, the number of retransmissions is mainly configured through high-level signaling Radio Resource Control (RRC) signaling, and must be configured through dedicated PUCCH resources (dedicated PUCCH resources).

However, the current configuration of the number of PUCCH retransmissions is semi-static.

Detailed ways

As described in the Background Art, the current configuration method of the number of PUCCH retransmissions is semi-static. However, in the semi-static period, the uplink transmission conditions may change, and the number of retransmissions is no longer applicable to the current transmission conditions, resulting in inconsistent uplink data. Transmission is affected.

The technical solution of the present invention can be applied to 5G (5Generation) communication systems, 4G and 3G communication systems, and various new communication systems in the future, such as 6G and 7G.

In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a flowchart of a method for determining PUCCH retransmission according to an embodiment of the present invention.

The method for determining PUCCH retransmission may be used on the side of a user equipment (User Equipment, UE), that is, each step of the method shown in FIG. 1 may be performed by the user equipment.

Specifically, the PUCCH retransmission determination method may include the following steps:

Step S101: Receive downlink signaling, where the downlink signaling includes the correspondence between the number of PUCCH retransmissions and PUCCH resources;

Step S102: Determine the number of retransmissions of the PUCCH to be sent according to the PUCCH resources used by the PUCCH to be sent and the corresponding relationship, or determine the number of retransmissions of the PUCCH to be sent according to the number of retransmissions of the PDSCH associated with the PUCCH to be sent. The number of retransmissions, or at least the number of retransmissions of the PUCCH to be sent is determined according to the number of retransmissions of the sent PUCCH whose transmission timing is closest to the transmission timing of the to-be-sent PUCCH.

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

It can be understood that, in a specific implementation, the PUCCH retransmission determination method may be implemented by a software program, and the software program runs in a processor integrated inside a chip or a chip module. The method can also be implemented by combining software with hardware, which is not limited in this application.

The number of retransmissions mentioned in the embodiment of the present invention refers to the number of repeated transmissions.

All the embodiments given in the present invention can also be applied to some PUCCHs carrying dedicated information for repeated transmission. Wherein, the proprietary information may include at least one of the following information: scheduling request (scheduling request, SR), beam failure scheduling request (beam failure recovery scheduling request, BFR-SR), CSI, beam failure recovery (beam failure recovery, BFR) information, HARQ-ACK.

In this embodiment, the network side may pre-configure the correspondence between the number of PUCCH retransmissions and the PUCCH resources, and notify the UE through downlink signaling. The UE may learn the correspondence between the number of PUCCH retransmissions and the PUCCH resources through downlink signaling. The downlink signaling may be selected from RRC, MAC CE, and DCI, or any other implementable downlink signaling, which is not limited in this embodiment of the present invention.

In a specific implementation, the corresponding relationship between the number of PUCCH retransmissions and the PUCCH resources may be the corresponding relationship between the number of PUCCH retransmissions and the resource index of the PUCCH resources, or may be the number of PUCCH retransmissions and the time domain length (such as the number of symbols) occupied by the PUCCH resources. , also referred to as the corresponding relationship of symbol duration), etc., which will not be repeated in this embodiment of the present invention.

Furthermore, in the specific implementation of step S102, when the UE transmits the PUCCH, the UE may search for the number of retransmissions corresponding to the resource matching the PUCCH resource used by the PUCCH to be sent in the above-mentioned correspondence, and based on the number of retransmissions found. PUCCH for transmission.

In a variation of the present invention, the number of retransmissions of the PUCCH to be sent is determined according to the number of retransmissions of the Physical Downlink Shared Channel (PDSCH) associated with the PUCCH to be sent. The association may refer to that the HARQ-ACK information of the PDSCH is carried by the PUCCH.

In this embodiment, the number of retransmissions of the PUCCH is associated with the number of retransmissions of the associated PDSCH. Since PDSCH and PUCCH may have different coverage performance requirements, the number of retransmissions of PUCCH may be inconsistent with the number of retransmissions of PDSCH, but they are numerically related. That is, the number of retransmissions of the PUCCH can be calculated or derived from the number of retransmissions of the PDSCH.

Specifically, the number of retransmissions of the PUCCH can be uniquely determined by the number of retransmissions of the PDSCH. The specific calculation relationship can be pre-configured by the base station through downlink signaling, or can be determined in a pre-defined manner, for example, the conversion relationship between the number of retransmissions of PDSCH and the number of retransmissions of PUCCH is pre-defined by a communication standard protocol.

For example, the number of PDSCH retransmissions is indicated as 2 times in the DCI, then the PUCCH can be 2+X times, or 2×X times, or the same as the number of PUCCH retransmissions and PDSCH retransmission times, where X is a positive integer greater than or equal to 1 . The specific value of X may be pre-configured by the base station through downlink signaling, or may be pre-defined by a standard protocol.

It should be noted that the calculation of the number of retransmissions of the PUCCH by using the number of retransmissions of the PDSCH may also be any other implementable more complex calculation formula, which is not limited in this embodiment of the present invention.

In another variation of the present invention, the number of retransmissions of the to-be-sent PUCCH is determined at least according to the number of retransmissions of the sent PUCCH whose transmission timing is closest to the transmission timing of the to-be-sent PUCCH. That is to say, it can be determined that the number of retransmissions of the sent PUCCH with the closest timing is the number of retransmissions of the PUCCH to be sent.

In this embodiment of the present invention, by indicating the correspondence between the number of PUCCH retransmissions and the PUCCH resources to the user equipment in the downlink signaling, the user equipment can determine the number of retransmissions according to the PUCCH resources actually used during PUCCH transmission; The number of retransmissions is determined according to the number of retransmissions of the associated PDSCH; or in each PUCCH transmission, the number of retransmissions is determined according to the number of retransmissions of the sent PUCCH whose transmission timing is closest to the transmission timing of the to-be-sent PUCCH, thereby enabling dynamic The number of PUCCH retransmissions is determined, so that the number of PUCCH retransmissions can be applied to the current transmission conditions, so as to ensure the normal transmission of the PUCCH and the normal interaction between the user equipment and the network side.

In a non-limiting embodiment of the present invention, the downlink signaling includes the correspondence between the number of PUCCH retransmissions and the length of the time domain occupied by the PUCCH resources. As shown in Table 1 below.

Table 1

As shown in Table 1, when the length of the time domain occupied by the PUCCH resources is 4 symbols, the number of retransmissions of the PUCCH is 2, and when the length of the time domain occupied by the PUCCH resources is 5 symbols, the number of retransmissions of the PUCCH is 4, By analogy, when the time domain length occupied by the PUCCH resource is 14 symbols, the number of retransmissions of the PUCCH is 32. The above correspondence may be sent by the base station to the UE through RRC signaling, or predefined by a communication standard protocol.

Furthermore, step S102 shown in FIG. 1 may include the following steps: determining the number of PUCCH retransmission times corresponding to the time domain length occupied by the PUCCH resource used by the PUCCH to be sent according to the corresponding relationship, as the number of retransmissions of the PUCCH to be sent Number of retransmissions. For example, the PUCCH resource used by the PUCCH to be sent is 5 symbols, and it can be determined that the number of retransmissions of the PUCCH to be sent is 4 by looking up Table 1 above.

In another non-limiting embodiment of the present invention, the downlink signaling includes the correspondence between the number of PUCCH retransmissions and the length of the time domain occupied by the PUCCH resources under the PUCCH of each format. The following table 2 shows the correspondence between the number of symbols and the number of retransmissions under the PUCCH of Format 3 (Format 3).

The above correspondence may be sent by the base station to the UE through RRC signaling, or predefined by a communication standard protocol.

Furthermore, step S102 shown in FIG. 1 may include the following steps: determining the number of PUCCH retransmissions corresponding to the time domain length in the format of the PUCCH resource used by the to-be-sent PUCCH as the number of retransmissions of the to-be-sent PUCCH. For example, the format of the PUCCH to be sent is Format 3, the used PUCCH resource is 5 symbols, and it can be determined that the number of retransmissions of the PUCCH to be sent is 4 by looking up Table 2 above.

In a specific embodiment of the present invention, the downlink signaling includes RRC signaling, and the number of retransmissions corresponding to the PUCCH resource is updated or indicated by combining RRC and MAC CE. The PUCCH resource may be identified by a PUCCH resource index (PUCCH Resource Index, PRI). The RRC signaling includes the correspondence between the times of multiple PUCCH retransmissions and the PUCCH resource index, and the MAC CE includes the group identifier. Step S102 shown in FIG. 1 may include the following steps: searching for multiple groups of PUCCH retransmission times corresponding to the resource index of the PUCCH resource used by the to-be-sent PUCCH according to the corresponding relationship; The number of retransmissions of the PUCCH indicated by the group identifier carried in the MAC CE is determined as the number of retransmissions of the PUCCH to be sent.

The embodiment of the present invention updates the number of retransmissions corresponding to the PUCCH resource by combining RRC and MAC CE. Specifically, the base station configures the corresponding multiple groups of retransmission times for each PUCCH resource index (PUCCH Resource Index, PRI) through RRC, and each group of retransmission times has a group identifier, and then uses the MAC CE to update which group is specifically applied. Wherein, each group of retransmission times may uniquely correspond to one retransmission number.

In another specific embodiment of the present invention, the downlink signaling includes resource configuration signaling, the resource configuration signaling includes the correspondence between the times of multiple PUCCH retransmissions and PUCCH resources, and the DCI includes PUCCH resource retransmissions number of indications. Optionally, the base station may activate or deactivate the number of PUCCH resource retransmissions through the MAC CE. Step S102 shown in FIG. 1 may include the following steps: determining the number of PUCCH retransmissions corresponding to the PUCCH resource index carried in the DCI in the majority correspondence, as the number of retransmissions of the PUCCH to be sent.

In another specific embodiment of the present invention, when configuring PUCCH resources for the UE through downlink signaling, the base station configures the corresponding number of retransmissions for each resource at the same time, that is, the corresponding relationship between the number of PUCCH retransmissions and the PUCCH resources. Therefore, when the base station indicates the specific PRI to the UE through the DCI, it also implicitly indicates the number of retransmissions to the UE.

In a non-limiting embodiment of the present invention, the PUCCH to be sent is a periodic PUCCH or a semi-persistent PUCCH. In this case, determine the sent PUCCH that is closest to the sending timing of the to-be-sent PUCCH and has the same format, and use the number of retransmissions of the sent PUCCH as the number of retransmissions of the to-be-sent PUCCH; or, Determine the sent aperiodic PUCCH that is closest to the sending timing of the to-be-sent PUCCH and has the same format, and uses the number of retransmissions of the sent PUCCH as the number of retransmissions of the to-be-sent PUCCH; The sending timing of the PUCCH to be sent is the closest and the sent PUCCH carrying HARQ-ACK information in the same format, and the number of retransmissions of the PUCCH that has been sent is taken as the number of retransmissions of the PUCCH to be sent; Send the PUCCH with the closest PUCCH sending timing and the same format that has sent the number of retransmissions greater than 1, and use the number of retransmissions of the sent PUCCH as the number of retransmissions of the PUCCH to be sent; Send the sent PUCCH with the closest sending opportunity, the same format and the same occupied time domain length, and use the number of retransmissions of the sent PUCCH as the number of retransmissions of the PUCCH to be sent; or, determine the number of retransmissions of the PUCCH to be sent; A sent aperiodic PUCCH with the closest sending timing of the PUCCH to be sent, the same format, and the same occupied time domain length, and the number of retransmissions of the sent aperiodic PUCCH as the number of retransmissions of the to-be-sent PUCCH; or , determine the sent PUCCH carrying HARQ-ACK information that is closest to the sending timing of the to-be-sent PUCCH, has the same format, and the same occupied time domain length, and uses the number of retransmissions of the sent aperiodic PUCCH as the The number of retransmissions of the PUCCH to be sent; or, determine the PUCCH that is closest to the sending timing of the PUCCH to be sent, has the same format, and has the same time domain length that has been sent with the number of retransmissions greater than 1, and assigns the sent non- The number of retransmissions of the periodic PUCCH is taken as the number of retransmissions of the PUCCH to be sent; Optionally, the time difference between the sending time of the sent PUCCH and the sending time of the to-be-sent PUCCH needs to be smaller than a preset threshold. The preset threshold may be configured by downlink signaling or pre-defined by a communication standard protocol.

Specifically, the format of the periodic or semi-persistent PUCCH is pre-defined as x, and the number of retransmissions can only refer to the number of retransmissions used by the PUCCH with the latest transmission timing and the same format, which carries HARQ-ACK information.

Alternatively, the format of the periodic or semi-persistent PUCCH is pre-defined as x, and the number of retransmissions thereof may only refer to the number of retransmissions used by the aperiodic PUCCH with the latest transmission timing and the same format.

Alternatively, the format of the periodic or semi-persistent PUCCH is pre-defined as x, and the number of retransmissions only refers to the number of retransmissions used by the PUCCH with the latest transmission opportunity, the same format, and the number of retransmissions greater than 1.

Alternatively, the format of the periodic or semi-persistent PUCCH is predefined as x, and the number of retransmissions may only refer to the number of retransmissions used by the PUCCH with the latest transmission opportunity, the same format and the same number of symbols, which carries HARQ-ACK information.

Alternatively, the format of the periodic or semi-persistent PUCCH is predefined as x, and the number of retransmissions can only refer to the number of retransmissions used by the aperiodic PUCCH with the latest transmission opportunity, the same format, and the same number of symbols.

Alternatively, the format of the periodic or semi-persistent PUCCH is pre-defined as x, and the number of retransmissions may only refer to the number of retransmissions used by the PUCCH with the latest transmission opportunity, the same format, the same number of symbols, and the number of retransmissions greater than 1. Further, if there is no sent PUCCH that meets the above requirements, the UE may transmit the periodic or semi-persistent PUCCH according to a predefined number of retransmissions. For example, retransmission may be performed according to the maximum allowable number of retransmissions, or the default number of retransmissions is 1.

As a variation example, the format of the periodic or semi-persistent PUCCH is pre-defined as x and the number of symbols is y, if the number of symbols corresponding to the last PUCCH that meets the requirements is z and the number of retransmissions is N. Then, the number M of retransmissions of the periodic or half-held PUCCH is jointly determined by y, z, and N. For example, the number of retransmissions M is calculated using the following formula: M=N×round(z/y), or M=N×ceil(z/y), or M=N×floor(z/y), where round( ) function means rounding up floating point numbers, ceil() function means rounding up to the nearest integer; floor() function means rounding down to the nearest integer.

In a non-limiting embodiment of the present invention, the PUCCH to be sent is a periodic or semi-persistent PUCCH, and the PUCCH resource or the number of retransmissions corresponding to the PUCCH format can be indicated by the MAC CE. Specifically, the MAC CE may include at least one of the following indication information: the format of the PUCCH resource, the PUCCH resource index, and the number of times of retransmission of the PUCCH resource. In this case, the number of retransmissions indicated in the MAC CE is taken as the number of retransmissions of the PUCCH resource to be sent; or the number of retransmissions indicated in the MAC CE is taken as the number of retransmissions corresponding to the indicated PUCCH format, i.e. The PUCCH resources with the same PUCCH format will use the retransmission times indicated in the MAC CE for repeated transmission.

In this embodiment, the number of retransmissions of the periodic or semi-persistent PUCCH is updated/indicated by the MAC CE. The specific MAC CE may be an update/indication of the number of retransmissions of a PUCCH in a certain format, or may be an update/indication of the number of retransmissions more accurate to a certain PUCCH resource (that is, a PUCCH resource index). .
