Patent Description:
In New Radio Access Technologies (NR) R16, a terminal may support various service types simultaneously, e.g., enhanced Mobile Broadband (eMBB) and Ultra Reliably & Low Latency Communications (URLLC).

When a Physical Uplink Control Channel (PUCCH) carrying a Hybrid Automatic Repeat reQuest Acknowledgement (HARQ-ACK, including HARQ-ACK/NACK) overlaps a Grant-Free (GF) Physical Uplink Shared Channel (PUSCH), a GF PUSCH resource is configured semi-statically, and it cannot change dynamically. When the HARQ-ACK needs to be transferred to be transmitted on the PUSCH, the HARQ-ACK may probably occupy a part of the PUSCH resources, and thereby the transmission performance of data carried on the PUSCH is adversely affected. Especially when the PUSCH carries URLLC data where the reliability may be highly demanded, the transmission reliability is reduced due to a decrease in the transmission resources. However, the HARQ-ACK is also important, and especially when the HARQ-ACK also corresponds to the URLLC, it is unable to ensure the transmission reliability of the PUSCH through discarding the HARQ-ACK. Currently, there is no definite scheme about the transmission when the HARQ-ACK overlaps the Grant-Free (GF) PUSCH.

<CIT> relates to HARQ feedback on unlicensed spectrum subject to Listen-Before-Talk rules.

<CIT> relates to a base station apparatus, a terminal apparatus, and a communication method thereof.

<CIT> relates to grant-less Physical Uplink Shared Channel (PUSCH) uplinks. <CIT> relates to configurations of a base station apparatus, a terminal apparatus, and a communication method.

An object of the present disclosure is to provide a transmission method, a reception method, a terminal and a network device, so as to solve the problem in the related art where the performance of the PUSCH transmission is adversely affected when the HARQ-ACK transmission overlaps the GF PUSCH transmission and an existing transmission processing mode is adopted, and thereby it is impossible to ensure the transmission reliability.

The invention made is disclosed in the embodiment described in <FIG>.

The present invention is defined by the attached independent claims. Advantageous embodiments are described in the attached dependent claims. Embodiments and/or examples mentioned in the description that do not fall under the scope of the claims are useful for understanding the present invention. In order to make the objects, the technical solutions and the advantages of the present disclosure more apparent, the present disclosure will be described hereinafter in in details in conjunction with the drawings and embodiments.

Firstly, some concepts involved in the embodiments of the present disclosure will be described hereinafter.

Along with the change in the demands on mobile communication services, many organizations, e.g., International Telecommunication Union (ITU), have started to study a new radio communication system (i.e., <NUM>th Generation New Radio Access Technologies (<NUM> NR)). In the <NUM> NR, the simultaneous transmission of a PUCCH and a PUSCH is not supported. When PUCCH overlaps the PUSCH, UCI carried in the PUCCH is transferred to be transmitted on the PUSCH. Currently, merely an HARQ-ACK (including HARQ-ACK/NACK) and CSI are supported to be transmitted on the PUSCH. If there is an SR in the UCI and the PUSCH does not carry any data (i.e., UL-SCH), the PUSCH is discarded; otherwise, the SR is discarded.

A scheme for the transmission of the HARQ-ACK on the PUSCH is related to the quantity of bits. When the HARQ-ACK has no more than two bits, it is transmitted in a punching manner. In other words, the data on the PUSCH is transmitted in a mode where no resource is occupied by the HARQ-ACK, and the HARQ-ACK is transmitted through punching data information at a mapping position. A data rate is not adversely affected by the transmission of the HARQ-ACK on the PUSCH, but it is equivalent to that the HARQ-ACK is transmitted through covering a part of the data information, so the data transmission performance is adversely affected to some extent. When the HARQ-ACK has more than two bits, it is transmitted in a rate matching mode. In other words, a size of a resource occupied by the HARQ-ACK on the PUSCH is calculated in accordance with such information as a resource offset parameter (beta-offset). Then, encoding, rate matching and mapping are performed on the HARQ-ACK in accordance with the size of the occupied resource, and encoding, rate matching and mapping are performed on the data on resources of the PUSCH other than that occupied by the HARQ-ACK, i.e., the HARQ-ACK and the data are transmitted on different resources of the PUSCH. The data rate is adversely affected due to the existence of the HARQ-ACK, so the data transmission performance is adversely affected too.

The CSI is transmitted on the PUSCH in a rate matching manner, which is similar to the HARQ-ACK having more than two bits.

When the PUSCH overlaps the PUCCH, the performance of the PUSCH transmission is adversely affected because the UCI is transferred to be transmitted on the PUSCH. Currently, there is no definite method for ensuring the performance of the PUSCH transmission when the PUCCH transmission overlaps the PUSCH transmission.

When the transmission of the HARQ-ACK overlaps the transmission of the GF PUSCH, in an existing transmission processing mode, the performance of the PUSCH transmission is adversely affected, so it is impossible to ensure the transmission reliability. In this regard, an object of the present disclosure is to provide a transmission method, a reception method, a terminal and a network device so as to solve the above problem.

As shown in <FIG>, the present disclosure provides in some embodiments a transmission method for a terminal, which includes Steps <NUM> and <NUM>.

Step <NUM>: receiving configuration information transmitted from a network device, to obtain a configuration parameter of a GF PUSCH;
it should be appreciated that, the configuration information may be transmitted by the network device to the terminal through Radio Resource Control (RRC) signaling or DCI.

Step <NUM>: performing PUSCH transmission in accordance with the configuration parameter, wherein the configuration parameter is configured based on an existence of A bits of first UCI to be transmitted on the PUSCH, and the A represents a predetermined quantity of bits; or determining a PUSCH transmission resource in accordance with the configuration parameter and whether there is the first UCI to be transmitted on the PUSCH, and performing PUSCH transmission on the determined PUSCH transmission resource.

Various implementations of Step <NUM> will be specifically described hereinafter. Step <NUM> specifically includes performing PUSCH transmission in accordance with the configuration parameter, wherein the configuration parameter is configured based on an existence of A bits of first UCI to be transmitted on the PUSCH, and the A represents a predetermined quantity of bits.

To be specific, in this case, Step <NUM> includes:.

It should be appreciated that, the configuration parameter of the PUSCH is configured by the network device when there is the first UCI having A bits transmitted on the PUSCH. When the PUSCH transmission resource is being determined by the terminal and A is greater than <NUM>, the HARQ-ACK having more than two bits is transmitted on the PUSCH in a rate matching manner, so a transmission resource for the first UCI having A bits is always reserved in the PUSCH transmission resources, i.e., no matter whether there is the first UCI, the rate matching needs to be performed on the data transmission on the PUSCH on the basis of such a hypothesis that there is the first UCI having A bits. Except the resource occupied by the first UCI, the encoding, the data rating and the mapping are performed on the data in accordance with the remaining resources. In other words, when the first UCI needs to be transmitted on the PUSCH, due to the reserved transmission bits for the first UCI, the first UCI does not occupy the transmission resources on the PUSCH which have been allocated for the data, so the data transmission performance on the PUSCH is not adversely affected. It should be appreciated that, in order to prevent a data rate on the PUSCH when there is the first UCI from being different from that when there is no first UCI, no matter whether there is the first UCI, the rate matching needs to be performed on the data on the PUSCH and the data needs to be transmitted on the basis of such a hypothesis that there is the first UCI having A bits. It should be further appreciated that, in this case, when the first UCI needs to be transmitted on the PUSCH, an actual quantity of bits of the first UCI shall not be greater than A, and if it is greater than A, it is impossible for the transmission performance of the first UCI to achieve a desired effect. In one mode, erroneous scheduling is determined, and in another mode, the first UCI is transmitted through conventional steps. However, at this time, the resources allocated for the first UCI merely meet the requirement on the transmission of at most A bits, and a code rate of the first UCI having more than A bits is greater than an expected code rate, so the transmission performance of the first UCI will be deteriorated. When A is not greater than <NUM>, the HARQ-ACK having not more than two bits is transmitted on the PUSCH in a data punching manner, so no matter whether there is the first UCI, the data on the PUSCH is always transmitted in accordance with a size of all the configured PUSCH resources (encoding, rate matching, mapping, etc.). In other words, the code rate and a mapping resource of the PUSCH are not adversely affected no matter whether there is the first UCI. When there is no first UCI, the data is transmitted normally on all the resources, and when there is the first UCI, the first UCI is transmitted through punching data at corresponding positions in accordance with the desired resources, and the data transmission performance on the PUSCH is probably deteriorated due to the punched data. In order to prevent the data transmission performance from being deteriorated, it is considered to always configure all the PUSCH resources on the basis of such a hypothesis that these resources are punched by the first UCI, so as to achieve the desired data transmission performance on the PUSCH even when there is the first UCI transmitted in a punching manner. At this time, when there is no first UCI transmitted in a punching manner, it is able to achieve better data transmission performance on the PUSCH than a desired transmission performance. In a word, through an appropriate resource configuration, it is able to achieve the desired performance even in the worst case.

It should be further appreciated that, A is an integer greater than or equal to <NUM>. For example, A is <NUM> or <NUM>. It should be noted that, A may be alternatively a value greater than <NUM>, e.g., <NUM>, through agreement. A scheme of transmitting the first UCI on the PUSCH when the first UCI is the HARQ-ACK is affected by whether A is greater than <NUM>. When A is not greater than <NUM>, it is always assumed that the first UCI is transmitted on the PUSCH in a punching manner, and the rate matching and mapping of the data transmission on the PUSCH is not affected by whether there is the first UCI. When A is greater than <NUM>, it is always assumed that the first UCI is transmitted on the PUSCH in a rate matching manner. When the PUSCH transmission is performed on the resource determined in accordance with the configuration parameter, the rate matching and mapping need to be performed on the data on the PUSCH in accordance with the resources other than the resource occupied by the first UCI having A bits, no matter whether there is the first UCI.

It should be further appreciated that, when the first UCI needs to be transmitted on the PUSCH, a PUCCH carrying the first UCI overlaps the PUSCH and a predetermined time condition has been met. For example, a time interval between a first symbol in an earlier one of the PUCCH and the PUSCH and a last symbol in DCI corresponding to the PUCCH or the PUSCH is not smaller than T1, and a time interface between the first symbol in the earlier one of the PUCCH and the PUSCH and a last symbol in a PDSCH corresponding to the PUCCH is not smaller than T2, as indicated in TS <NUM>.

Step <NUM> specifically includes determining a PUSCH transmission resource in accordance with the configuration parameter and whether there is the first UCI to be transmitted on the PUSCH, and performing PUSCH transmission on the determined PUSCH transmission resource.

In a possible embodiment of the present disclosure, in this case, when the configuration parameter includes at least two PUSCH resources, Step <NUM> includes:.

It should be appreciated that, in this case, at least two PUSCH resources are configured. When the first UCI does not need to be transmitted on the PUSCH, one PUSCH resource is used, and when the first UCI needs to be transmitted on the PUSCH, another PUSCH resource is used. For example, two PUSCH resources, i.e., a PUSCH resource <NUM> and a PUSCH resource <NUM>, have been configured by the network device, and a size of the PUSCH resource <NUM> (i.e., a quantity of bits capable of being carried by the PUSCH resource <NUM> or a total quantity of Resource Elements (REs) for carrying the UCI and the data in the PUSCH resource <NUM>) is smaller than a size of the PUSCH resource <NUM>. When the first UCI does not need to be transmitted on the PUSCH, the PUSCH transmission is performed on the PUSCH resource <NUM>, and when the first UCI needs to be transmitted on the PUSCH, the PUSCH transmission is performed on the PUSCH resource <NUM>.

It should be further appreciated that, when the second PUSCH resource includes more than one PUSCH resource, different PUSCH resources in the second PUSCH resource are used to transmit the first UCIs having different quantities of bits,
wherein sizes of different PUSCH resources in the second PUSCH resource are different.

For example, three PUSCH resources, i.e., a PUSCH resource <NUM>, a PUSCH resource <NUM> and a PUSCH resource <NUM>, have been configured by the network device. When the first UCI does not need to be transmitted on the PUSCH, the PUSCH transmission is performed on the PUSCH resource <NUM>. When the first UCI needs to be transmitted on the PUSCH and the quantity of bits of the first UCI does not exceed N, the PUSCH transmission is performed on the PUSCH resource <NUM>. When the quantity of bits of the first UCI is greater than N, the PUSCH transmission is performed on the PUSCH resource <NUM>. For the sizes of the PUSCH resources (i.e., a quantity of bits capable of being carried by the PUSCH resource or a total quantity of REs for carrying the UCI and the data in the PUSCH resource), the size of the PUSCH resource <NUM>>the size of the PUSCH resource <NUM>>the size of the PUSCH resource <NUM>.

In another possible embodiment of the present disclosure, in this case, Step <NUM> includes:.

It should be appreciated that, in this case, one PUSCH transmission resource has been configured. When the first UCI does not need to be transmitted on the PUSCH, the PUSCH transmission merely needs to be performed in accordance with the configured PUSCH transmission resource. When the first UCI needs to be transmitted on the PUSCH, the configured PUSCH transmission resource is not used directly, and instead, the PUSCH transmission resource is expanded, e.g., combined with the additional resource, to obtain a new PUSCH transmission for the transmission of the PUSCH.

It should be appreciated that, a size of the additional resource is (A1) pre-defined in a protocol, (A12) configured through signaling (e.g., configured by the network device through RRC signaling or DCI), or (A13) determined in accordance with a requirement on the transmission of the first UCI. The mode A13 is determined by the terminal by itself in accordance with the requirement on the transmission of the first UCI. For example, the size of the corresponding transmission resource is calculated in accordance with the quantity of bits of the first UCI and a target code rate.

To be specific, the additional resource includes X1 OFDM symbols and/or X2 RBs, where X1 represents a predetermined quantity of OFDM symbols, e.g., <NUM>, and X2 represents a predetermined quantity of RBs, e.g., <NUM>.

Further, when the additional resource includes X1 OFDM symbols, the determining the target PUSCH transmission resource in accordance with the determined PUSCH transmission resource and the additional resource includes one of the following modes:.

To be specific, when the additional resource includes X2 RBs, the determining the target PUSCH transmission resource in accordance with the determined PUSCH transmission resource and the additional resource includes one of the following modes:.

First condition: the first UCI is at least one of an HARQ-ACK or CSI, and the PUSCH corresponds to a first type of service or a second type of service.

It should be appreciated that, the first type of service is at least one of the followings.

(B <NUM>) A service having a high priority level or a high significance level.

It should be appreciated that, the first type of service is a service having a relatively high priority level, or a service having a relatively high significance level.

It should be appreciated that, the second type of service is at least one of the followings.

(B21) A service having a low priority level or a low significance level.

It should be appreciated that, the second type of service is a service having a relatively low priority level, or a service having a relatively low significance level.

Here, it should be appreciated that, the second type of service is also a non-URLLC service other than the eMBB service.

It should be further appreciated that, the priority level, the significance level or the type of service is determined in accordance with at least one of a DCI format, a DCI size, an RNTI, a search space, a Control Resource Set (CORESET), a beam, a BLER, a CQI table, an MCS table, a priority level identifier, a PUCCH resource or an SR configuration index number.

It should be appreciated that, which one of the first UCI and the PUSCH is more important is determined in accordance with at least one of the above information. When the first UCI has a higher priority level than, or a same priority level as, the PUSCH, the operation is performed in accordance with the above rule; otherwise, the first UCI is directly discarded.

For example, a service corresponding to a first type of related information, e.g., a first type of DCI format, a first type of DCI size, a first type of RNTI, a first type of search space, a first type of CORESET, a first type of beam, a first type of BLER (e.g., <NUM>-<NUM> or <NUM>-<NUM>), a first type of CQI table (e.g., a URLLC CQI table), a first type of MCS table (e.g., a URLLC MCS table), a first type of priority identifier, a first type of PUCCH resource (e.g., a resource with a small index number or a specific index number or a resource corresponding to a specific SR configuration index number), or a first type of SR configuration index number (e.g., an SR configuration with a smaller index number is considered to correspond to URLLC in the case that a plurality of SR configurations has been configured) is the first type of service. A service corresponding to a second type of related information, e.g., a second type of DCI format, a second type of DCI size, a second type of RNTI, a second type of search space, a second type of CORESET, a second type of beam, a second type of BLER (e.g., <NUM>-<NUM> or <NUM>-<NUM>), a second type of CQI table (e.g., a <NUM> Quadrature Amplitude Modulation (QAM) or <NUM> QAM CQI table), a second type of MCS table, a second type of priority identifier, a second type of PUCCH resource (e.g., a resource with a large index number or a specific index number or a resource corresponding to a specific SR configuration index number), or a second type of SR configuration index number (e.g., an SR configuration with a larger index number is considered to correspond to eMBB or non-URLLC in the case that a plurality of SR configurations has been configured) is the second type of service. A corresponding service type is obtained in accordance with the related information corresponding to the first UCI and the PUSCH. For another example, when it is specified in advance that the first type of related information has a higher priority level or significance level than the second type of related information, a comparison result between the priority level or the significance comparison result of the first UCI and that of the PUSCH is obtained in accordance with the related information corresponding to the first UCI and the PUSCH.

Second condition: the first UCI is at least one of an HARQ-ACK corresponding to the first type of service or CSI corresponding to the first type of service, and the PUSCH corresponds to the first type of service.

Third condition: the first UCI is at least one of an HARQ-ACK corresponding to a second type of service or CSI corresponding to the second type of service, and the PUSCH corresponds to the first type of service or the second type of service.

Based on a transmission mode of the terminal, the network device receives the information in a same mode.

The applications of the method in the embodiments of the present disclosure will be illustratively described hereinafter on the basis of the terminal and a base station.

It is presumed that A=<NUM>. A GF PUSCH resource is always configured on the basis of a size of a resource for transmitting HARQ-ACK having two bits on the PUSCH. When T1 REs are required for transmitting the HARQ-ACK having two bits in accordance with the requirement on the transmission performance, and T2 REs are required for performing PUSCH transmission in accordance with a Transport Block Size (TBS), the other transmission parameter (e.g., MCS, code rate) and the requirement on the transmission performance (e.g., whether the BLER is <NUM>-<NUM> or <NUM>-<NUM>), the PUSCH resource is always configured in accordance with T1+T2 REs. It should be noted that, the PUSCH resource may alternatively be configured in accordance with REs whose quantity is greater than T2 and smaller than T1+T2. This is because, the HARQ-ACK having less than two bits is transmitted in a punching manner, and the data rate is not adversely affected. However, due to the punching, some information in the data is probably lost. When the punched information is just redundant data encoding information, the performance is not adversely affected to a great extent. Hence, it is unnecessary to assume that a data resource occupied by the HARQ-ACK always needs to be completely compensated. The base station obtains a size of each of a time-domain resource and a frequency-domain resource of the PUSCH in accordance with the total quantity of REs determined on the basis of the above principle, and configures the transmission resource for the terminal in accordance with the sizes. When the PUSCH transmission is performed by the terminal in accordance with the transmission resource, it is able to ensure the transmission performance of the data on the PUSCH no matter whether there is the HARQ-ACK to be transmitted. The transmission is performed at a terminal side and a base station side in accordance with a transmission process in an existing mechanism. In other words, when the HARQ-ACK needs to be transmitted on the PUSCH, the HARQ-ACK and the data are transmitted on the PUSCH in a multiplexed manner, and when the HARQ-ACK does not need to be transmitted on the PUSCH, merely the data is transmitted. In the above two transmission cases, the same PUSCH resource is adopted.

It should be appreciated that, a behavior performed at the base station side is the same as that at the terminal side, and the PUSCH is received at the base station side on the corresponding PUSCH resource.

In the first circumstance, the configuration parameter of the GF PUSCH is configured always on the basis of the size of the resource for transmitting first UCI having A bits on the GF PUSCH, so as to ensure the performance of the PUSCH transmission, thereby to ensure the transmission reliability.

When configuring the GF PUSCH resources, two PUSCH resources, i.e., a PUSCH resource <NUM> and a PUSCH resource <NUM>, are configured, and a bearing capacity of the PUSCH resource <NUM> is smaller than that of the PUSCH resource <NUM>. For example, the PUSCH resource <NUM> occupies four symbols and four RBs, and the PUSCH resource <NUM> occupies six symbols and four RBs, or four symbols and eight RBs, or five symbols and seven RBs, i.e., the quantity of symbols or RBs, or both, occupied by the PUSCH resource <NUM> is different from that occupied by the PUSCH resource <NUM>. In addition, the symbols occupied by the PUSCH resource <NUM> include, or are totally different from, those occupied by the PUSCH resource <NUM>. For example, when the four symbols occupied by the PUSCH resource <NUM> include first to fourth symbols within one slot, and the PUSCH resource <NUM> also include four symbols, e.g., first to fourth, or fifth to eighth or second to fifth symbols. The RBs are configured in a same manner.

At the terminal side, when it determines that no HARQ-ACK needs to be transmitted on the PUSCH (e.g., there is no HARQ-ACK transmission or the PUSCH carrying the HARQ-ACK does not overlap the PUSCH resource), the PUSCH transmission is performed on the PUSCH resource <NUM>, and the PUSCH carries the data (It should be noted that, when Aperiodic CSI (A-CSI) is triggered, the PUSCH further carries the A-CSI). When it determines that the HARQ-ACK needs to be transmitted on the PUSCH (e.g., the PUCCH carrying the HARQ-ACK overlaps the PUSCH resource and the time condition has been met), the PUSCH transmission is performed on the PUSCH resource <NUM>, and the PUSCH carries the HARQ-ACK. Whether the HARQ-ACK is transmitted through punching or rate matching is determined in accordance with the quantity of bits of the HARQ-ACK.

It is presumed that the configured GF PUSCH resource includes four symbols, i.e., eighth to eleventh symbols, within a slot n in a time domain, and include four RBs, i.e., fifth to eighth RBs, in one Bandwidth Part (BWP) in a frequency domain.

At the terminal side, when it determines that no HARQ-ACK needs to be transmitted on the PUSCH (e.g., there is no HARQ-ACK transmission, or the PUCCH carrying the HARQ-ACK does not overlap the PUSCH resource), the PUSCH transmission is performed in accordance with the configuration resource, and the PUSCH carries data (it should be noted that, when A-CSI is triggered simultaneously, the PUSCH further carries the A-CSI). When it determines that the HARQ-ACK needs to be transmitted on the PUSCH (e.g., the PUCCH carrying the HARQ-ACK overlaps the PUSCH resource and the time condition has been met), the configured resource is expended by X1 symbols and/or X2 RBs to obtain a larger resource, the PUSCH transmission is performed on the larger resource, and the PUSCH carries the HARQ-ACK. Whether the HARQ-ACK is transmitted through punching or rate matching is determined in accordance with the quantity of bits of the HARQ-ACK.

Based on the above, when transmitting the GF PUSCH, an appropriate matched resource is selected in accordance with whether there is the first UCI to be transmitted on the PUSCH, or whether the configured GF resource is expanded to use the GF resource appropriately. As a result, it is able to prevent the transmission performance of the GF PUSCH from being adversely affected by the resource occupied by the UCI, thereby to ensure the transmission reliability.

It should be further appreciated that, the above description has been given merely by taking the HARQ-ACK as an example, and the method is also applicable to the CSI. In the embodiments of the present disclosure, the PUSCH is a URLLC PUSCH, and the HARQ-ACK is an eMBB or URLLC PUSCH. It should be noted that, the method is also applicable when the PUSCH is an eMBB PUSCH.
