Description

Resource multiplexing transmission method and device
Technical Field
The present application relates to the field of communications technologies, and in particular, to a resource multiplexing transmission method and apparatus.
Background
Low-delay high-reliability Communication (URLLC) is a key scenario defined by 5G Communication, and the URLLC service is mainly characterized by having extremely high requirements on transmission delay and reliability, for example, it is necessary to ensure that the transmission reliability is greater than 99.9999% within 1ms delay. The important application scenes are industrial automation, including action control, communication among controllers, wireless replacement of an industrial wired network, closed-loop control of processing automation and the like. Therefore, for the URLLC service with extremely low time delay, the transmission reliability can be improved only by using a repeated transmission mode, that is, the transmitting end performs repeated independent transmission of data of transmission information for many times without waiting for ACK and NACK feedback, and the receiving end independently or jointly decodes information of multiple data copies, thereby increasing the possibility of successful reception within time limit and overcoming the problem of burst interference. However, the existing uplink repeat transmission scheme has low spectrum efficiency, and how to improve the spectrum efficiency of uplink resources while ensuring the high reliability of the URLLC service is an urgent problem to be solved.

It should be noted that these explanations are for the purpose of facilitating the understanding of the examples of the present application, and should not be construed as limiting the scope of the protection claimed in the present application.
1. Uplink URLLC repeat transmission
In order to ensure reliability of the URLLC service, the UE performs multiple repeated transmissions on data to be transmitted, where the repeated transmission is to transmit the same data on multiple independent time-frequency resources, and generally, the first transmission in the repeated transmission process is called initial transmission. It is understood that in the process of repeated transmission, besides the data on the first-bit transmitted time-frequency resource, the data on other independent time-frequency resources may be referred to as copies of the data to be transmitted.
The access network device configures a plurality of transmission configurations of the PUSCH (forming a Time Domain Resource Allocation (TDRA) table) for the UE through a physical uplink shared channel-Time Domain Resource Allocation (PUSCH-Time Domain Resource Allocation) field in a Radio Resource Control (RRC) signaling, including an interval between a downlink grant (DL grant) and the PUSCH, a repetition number, a Resource mapping type, a transmission start OFDM symbol, a continuous OFDM symbol number, and the like.
There are two ways for the access network device to indicate the available URLLC resources to the UE, one of which is dynamic scheduling (dynamic grant), that is, indicating the index number of the available URLLC resources in the time domain resource allocation (time domain resource assignment) field in the uplink grant (UL grant), and corresponding to a set of PUSCH transmission configurations in the configured TDRA table. Another is Configured Grant (CG), i.e. the index number of the available URLLC resource is indicated in the time domain allocation (time domain allocation) field in the pre-grant configuration (configured grant configuration) of the message as RRC signaling, and the configured grant may also be referred to as grant-free, dynamic grant-free, scheduling-free or dynamic scheduling-free corresponding to a set of PUSCH transmission configurations in the configured TDRA table.
A group of PUSCH transmission configurations in the TDRA table all include PUSCH resources required for repeated transmission of data for multiple times, and based on the configurations, the UE may directly perform repeated transmission, and thus does not need to wait for NACK feedback of the access network device.
On the time domain resource, the currently defined PUSCH repeated transmission mode in 5G-NR includes type a (type-a) and type B (type-B), as shown in fig. 2 (a) and (B), respectively.
In the embodiment of the present application, the time-frequency resource block in the PUSCH time-frequency resource used for transmission is referred to as a PUSCH sub-time-frequency resource, that is, the PUSCH time-frequency resource used for transmission includes a plurality of PUSCH sub-time-frequency resources. In the type-a repetition type, the time domain positions of the plurality of PUSCH sub-time-frequency resources in each slot are the same. The Type-A repetition Type has the advantages that the boundary of the time slot cannot be crossed among the plurality of PUSCH sub time frequency resources, and the defects that the time gaps exist among the plurality of PUSCH sub time frequency resources and the transmission can be completed in a longer time. In the Type-B repetition Type, a plurality of PUSCH sub time-frequency resources are continuous in a time domain, and a plurality of copies of data to be transmitted are continuously and repeatedly transmitted in sequence. If a downlink time slot (TDD system) or a time slot boundary is encountered, a plurality of PUSCH sub-time frequency resources can be split. The Type-B repetition Type has the advantages that a plurality of PUSCH sub-time-frequency resources are continuously transmitted in the time domain, the transmission delay is short, and the disadvantage is that the processing is complex when a downlink time slot or a time slot boundary is encountered.
On frequency domain resources, the repeated transmission of the PUSCH supports a frequency hopping mode and a non-frequency hopping mode, and the non-frequency hopping mode is that the frequency domain resources used by a plurality of PUSCH sub time-frequency resources in the repeated transmission process are the same. And for the frequency hopping mode, the frequency domain resources used by the plurality of PUSCH sub time-frequency resources are not completely the same. The standard now supports 2 hopping positions, calculated based on the following formula:
Figure BDA0003071803190000061
wherein RB start Initial transmission frequency domain configuration, RB, for PUSCH repeated transmission configured by access network equipment to UE through UL grant offset Configuring in RRC or configuring multiple RBs in PUSCH-Config of RRC signaling offset Indicated in the UL grant. For the Type-B repeat Type, the frequency hopping mode is further divided into inter-copy frequency hopping and inter-time slot frequency hopping, the inter-copy frequency hopping indicates that frequency hopping is carried out when each copy is transmitted, and the inter-time slot frequency hopping indicates that frequency hopping is carried out when the time slot on the time domain changes in the repeat transmission process.
In the NR Rel-15/16 version, for configured grant scenarios, in a repeated transmission process, on multiple PUSCH sub-time-frequency resources,the UE generates a demodulation reference signal (DMRS) sequence of the PUSCH based on the same scrambling seed, and decides a resource location of the DMRS based on an antenna port given by the same UL grant. For example, for a PUSCH with a transmit waveform of an OFDM waveform, the scrambling seed of the DMRS is

2. Degree of overlap
The overlapping degree in this application may be understood as the number of UEs performing data transmission on the same PUSCH sub time frequency resource when a plurality of UEs perform data transmission using the same PUSCH sub time frequency resource. That is, a plurality of UEs are allocated to use the same PUSCH sub time frequency resource, that is, PUSCH sub time frequency resources of a plurality of UEs overlap with each other. It is to be understood that the embodiment of the present application does not limit the specific names of the overlapping degrees, the overlapping degrees are only one possible name for describing the above functions, and other names that can realize the above functions are all understood to be the same as the overlapping degrees, such as the aliasing degrees, the resource multiplexing degrees, and the like.
3. First time frequency resource and copy time frequency resource
In the embodiment of the present application, a PUSCH sub time-frequency resource configured by an access network device and used for performing first transmission of data is referred to as a first time-frequency resource. It can be understood that the first time-frequency resource is only for convenience in describing the embodiment of the present application, and does not limit the name used by the first-transmitted PUSCH sub time-frequency resource, and other names capable of expressing the above PUSCH sub time-frequency resource may also be understood as having the same meaning as that of the first time-frequency resource, for example, the first-transmitted time-frequency resource, the initial transmission resource, and the like.
Besides the PUSCH sub time frequency resource for the first transmission, the PUSCH sub time frequency resource in other repeated transmission processes is called a replica time frequency resource. It can be understood that the duplicate time-frequency resource is only for convenience of describing the embodiment of the present application, and names used by other PUSCH sub time-frequency resources in the repetitive transmission process are not limited, and other names capable of expressing other PUSCH sub time-frequency resources in the repetitive transmission process may also be understood as having the same meaning as that of the duplicate time-frequency resource, for example, non-first time-frequency resources, non-first transmission time-frequency resources, and the like.
4. Successive Interference Cancellation (SIC)
Serial interference elimination is one of multi-user detection technologies, and the basic principle is that a receiving end decodes received signals of a plurality of users, one user is determined according to the sequence of the signal power of the received user, the interference caused by the user signal gradually tends to be generated, and therefore circulation operation is carried out all the time, and the signals of the users are gradually subtracted until all multiple access interference is eliminated.
The technical solution of the present application is described in detail below with reference to specific embodiments and accompanying drawings. The following examples and implementations may be combined with each other and may not be repeated in some examples for the same or similar concepts or processes. It will be appreciated that the functions explained herein may be implemented by means of individual hardware circuits, by means of software functioning in conjunction with a processor/microprocessor or general purpose computer, by means of an application specific integrated circuit and/or by means of one or more digital signal processors. When described as a method, the present application may also be implemented in a computer processor and a memory coupled to the processor.
Fig. 3 is a flowchart illustrating a resource multiplexing transmission method 300 according to an embodiment of the present application. The transmission method of resource multiplexing is illustrated in fig. 3 by taking a plurality of UEs and access network devices as an example of the execution subject of the interaction schematic. The subject matter of the interaction schematic is not limited in this application. For example, the UE device in fig. 3 may also be a chip, a chip system, or a processor supporting the UE device implementation method, and the access network device may also be a chip, a chip system, or a processor supporting the access network device implementation method.

By the method, the UE can obtain the PUSCH time-frequency resource configured by the access network equipment, and the UE can execute repeated transmission of uplink data according to the PUSCH time-frequency resource configuration to ensure the reliability of data transmission; from the perspective of the access network device, the same PUSCH sub time-frequency resources can be multiplexed when uplink data of multiple UEs are repeatedly transmitted, thereby improving the spectrum efficiency of the system time-frequency resources. The method 300 provided by the embodiments of the present application is described below.
Step 310: the UE transmits a Sounding Reference Signal (SRS), and accordingly, the access network equipment receives the SRS from the UE.
The access network equipment receives the SRS signal sent by the UE to obtain the measurement of the uplink channel quality parameter, and the access network equipment can schedule the PUSCH resource required by the UE according to the measurement value of the SRS signal.
Step 320: and the access network equipment sends second PUSCH configuration information to the plurality of UEs, and correspondingly, the UEs receive the second PUSCH configuration information. In an embodiment, the plurality of UEs includes at least three UEs.
The second PUSCH configuration information is used to indicate at least two duplicate time-frequency resources to the UE, and the access network device may send the second PUSCH configuration information to the UE through an RRC signaling.
And the UE receives the second PUSCH configuration information, and the UE can determine at least two copy time-frequency resources according to the second PUSCH configuration information.
In a possible implementation manner, the second PUSCH configuration information includes multiple sets of frequency hopping information, and each set of frequency hopping information may be used to generate at least two replica time-frequency resources. The access network device sends second PUSCH configuration information to the UE, and accordingly, the UE receives the second PUSCH configuration information, and the UE may obtain multiple sets of frequency hopping information in the second PUSCH configuration information.
Optionally, the access network device may indicate the group index number of the frequency hopping information to the UE through the second PUSCH configuration information, and the UE determines the frequency hopping information according to the group index number indicated by the access network device.
Step 330: the access network equipment sends first PUSCH configuration information to the UE, correspondingly, the UE receives the first PUSCH configuration information, and the UE can determine the first time-frequency resource of data transmission according to the first PUSCH configuration information.
In a possible implementation manner, the access network device may send, to the UE through dynamic signaling, the first PUSCH configuration Information (Downlink Control Information, DCI), where the first PUSCH configuration Information included in the DCI is used to indicate a first time-frequency resource for the UE to transmit data, and the first PUSCH configuration Information may include, for example, a start symbol, a start slot, an occupied symbol length, a start RB, and the like. It is to be understood that any parameter or parameter format that enables the UE to determine the first time-frequency resource may be used. The UE may determine a first time-frequency resource for data transmission according to the first PUSCH configuration information.
In a possible implementation manner, the access network device sends DCI to the UE, where the DCI includes the first PUSCH configuration information and a group index number of the frequency hopping information, where the first PUSCH configuration information is used to indicate a first time-frequency resource for the UE to transmit data, the group index number of the frequency hopping information is used to indicate a group index number of the frequency hopping information in the second PUSCH configuration information configured by the access network device in step 320, and the UE may obtain the frequency hopping information corresponding to at least two duplicate time-frequency resources according to the group index number.
In an embodiment, if the second PUSCH configuration information already indicates the group index number of the frequency hopping information, the first PUSCH configuration information may no longer include the group index number information.
Correspondingly, after the DCI is obtained, the UE obtains a first time frequency resource according to the first PUSCH configuration information in the DCI, determines frequency hopping information indicated by the second PUSCH configuration information according to the group index number of the frequency hopping information in the DCI, determines at least two duplicate time frequency resources according to the first time frequency resource and the frequency hopping information, and repeatedly transmits data through the first time frequency resource and the at least two duplicate time frequency resources.
In another possible implementation, the access network device may send the first PUSCH configuration information to the UE through a static or semi-static signaling, for example, an RRC signaling, where the RRC signaling includes a first time-frequency resource for transmitting data by the UE, and a parameter or a parameter format indicating the first time-frequency resource is not limited in this embodiment of the application, for example, the RRC signaling includes a start symbol, a start slot, an occupied symbol length, and a start RB. It is to be understood that any parameter or parameter format that enables the UE to determine the first time-frequency resource may be used. The UE may determine a first time-frequency resource for data transmission according to the first PUSCH configuration information. Optionally, when the access network device sends the first PUSCH configuration information to the UE through RRC signaling, the access network device may send, to the UE through the downlink control information DCI, the group index number of the frequency hopping information in the second PUSCH configuration information in step 320, where the group index number of the frequency hopping information is used to instruct the UE to obtain frequency hopping information corresponding to at least two replica time frequency resources.
Correspondingly, after the UE obtains the RRC signaling, the UE obtains a first time frequency resource according to the first PUSCH configuration information in the RRC signaling, after the UE obtains the DCI, the UE determines frequency hopping information indicated by the second PUSCH configuration information according to the group index number of the frequency hopping information in the DCI, the UE determines at least two duplicate time frequency resources according to the first time frequency resource and the frequency hopping information, and the UE performs repeated data transmission through the first time frequency resource and the at least two duplicate time frequency resources.
In the embodiment of the present application, the execution order of step 320 and step 330 may be different in some situations. The access network device sends the first PUSCH configuration information and the second PUSCH configuration information to the UE through different signaling, generally, the second PUSCH configuration information in step 320 is sent to the UE through RRC signaling, where the second PUSCH configuration information includes multiple sets of frequency hopping information, and the access network device may send the information in a unicast or broadcast manner. In step 330, the first PUSCH configuration information is a first time-frequency resource configured by the access network device to the UE for data repeat transmission, and generally, the access network device sends the first PUSCH configuration information by using DCI signaling. At this point, step 330 is performed after step 320. Step 330 may be performed before step 320, or step 330 may be performed after step 320, if the access network device transmits the first PUCCH configuration information using RRC signaling.
Step 340: and the UE sends data based on the configured PUSCH time-frequency resource, and correspondingly, the access network equipment receives the data of the UE.
And the UE determines at least two copy time-frequency resources according to the first time-frequency resource and the frequency hopping information in the second PUSCH configuration information, and repeatedly transmits data through the first time-frequency resource and the at least two copy time-frequency resources, so that the reliability of data transmission is ensured.
And the access network equipment receives the UE data based on the configured PUSCH time-frequency resource.
In a possible implementation manner, the UE may not have data to send, and accordingly, the access network device may not receive the data of the UE on the PUSCH time-frequency resource.
In the embodiment of the present application, step 310 is an optional step, that is, step 310 may not be included in the embodiment of the present application.
In one possible embodiment, if step 310 is included, the execution sequence of step 310 may be before step 320, or step 310 may be after step 320 and before step 330.
In the foregoing embodiment, the access network device configures, to the UE, PUSCH time frequency resources for repeated transmission of data, and indicates, to the UE, first time frequency resources for repeated transmission of data through the first PUSCH configuration information, and indicates, to the UE, duplicate time frequency resources for repeated transmission of data through the second PUSCH configuration information, where the first PUSCH configuration information and the second PUSCH configuration information are sent to the UE through different signaling.
From the perspective of the access network device, each UE of the at least three UEs obtains a corresponding first time-frequency resource and at least two replica time-frequency resources for performing repeated transmission of data of each UE, and each UE of the at least three UEs is respectively overlapped with different UEs on the at least two replica time-frequency resources, that is, PUSCH time-frequency resources between UEs are partially the same. The overlapping degree of each UE on the first time frequency resource is less than or equal to that on the replica time frequency resource.
By the method in the embodiment of the application, each UE in the at least three UEs can perform repeated transmission according to the PUSCH time-frequency resource configured by the access network equipment, and the PUSCH time-frequency resources among the at least three UEs are partially the same, so that the reliability of data transmission is ensured, and the spectrum efficiency of system resources is improved.
In the embodiment of the present application, the multiplexing pattern of the PUSCH resources among the at least three UEs is not limited, and in the embodiment of the present application, for example, in fig. 4, each block represents one PUSCH sub-time-frequency resource, for example, frequency domain resource 1 and time domain resource 1 constitute one PUSCH sub-time-frequency resource, and frequency domain resource 2 and time domain resource 1 constitute another PUSCH sub-time-frequency resource. It is to be understood that adjacent PUSCH sub time frequency resources in the figure are not necessarily adjacent in time domain or frequency domain, for example, PUSCH sub time frequency resource 1 and PUSCH sub time frequency resource 2 in fig. 4 (a) are not necessarily adjacent in frequency domain, and PUSCH sub time frequency resource 1 and PUSCH sub time frequency resource 4 are not necessarily adjacent in time domain. And the graphic identifiers of different UEs on one PUSCH sub time-frequency resource are only used for indicating that the PUSCH sub time-frequency resource is simultaneously allocated to different UEs for use, and the number of the UE graphic identifiers on each PUSCH sub time-frequency resource indicates the overlapping degree on the PUSCH sub time-frequency resource.
As shown in fig. 4 (a), the access network device configures PUSCH time-frequency resources for UE1, UE2, and UE3, where the PUSCH time-frequency resources of each UE include a first time-frequency resource and two replica time-frequency resources, for example, PUSCH sub-time-frequency resource 1 is the first time-frequency resource of UE3, PUSCH sub-time-frequency resources 6 and 8 are the two replica time-frequency resources of UE3, and likewise, PUSCH sub-time-frequency resource 3 is the first time-frequency resource of UE1, and PUSCH sub-time-frequency resources 8 and 10 are the two replica time-frequency resources of UE 1. As shown in fig. 4 (a), the first time-frequency resource corresponding to each UE is not overlapped, and the subsequent two duplicate time-frequency resources of each UE are respectively overlapped with different UEs, taking UE1 as an example, UE1 is overlapped with UE3 on the first duplicate time-frequency resource (PUSCH sub time-frequency resource 8) of UE1, and UE1 is overlapped with UE2 on the second duplicate time-frequency resource (PUSCH sub time-frequency resource 10) of UE 1. The overlapping degree of the first time frequency resource of each UE is 1, the overlapping degree of the two subsequent duplicate time frequency resources of the UE is 2, namely the overlapping degree of each UE on the first time frequency resource is less than or equal to the overlapping degree on the duplicate time frequency resource of the UE on the configured time frequency resources. As also shown in fig. 4 (b), the access network device configures PUSCH time-frequency resources for UEs 1 to 6, where the PUSCH time-frequency resources of each UE include a first time-frequency resource and two replica time-frequency resources, for example, PUSCH sub-time-frequency resource 3 is the first time-frequency resource of UE1, PUSCH sub-time-frequency resources 5 and 10 are the two replica time-frequency resources of UE1, meanwhile, PUSCH sub-time-frequency resource 3 is the first time-frequency resource of UE2, and PUSCH sub-time-frequency resources 5 and 9 are the two replica time-frequency resources of UE 2. Taking the PUSCH time-frequency resource of the UE1 as an example, the first time-frequency resource of the UE1 overlaps with the first time-frequency resource of the UE2, the overlapping degree on the first time-frequency resource of the UE1 is 2, and UEs aliased on the subsequent two duplicate time-frequency resources of the UE1 are not identical, for example, the UE1 overlaps with the UE2, the UE3, and the UE6 on the first duplicate time-frequency resource (PUSCH sub time-frequency resource 5) of the UE1, and the UE1 overlaps with the UE4, the UE5, and the UE6 on the second duplicate time-frequency resource (PUSCH sub time-frequency resource 10) of the UE 1. The overlap of the time-frequency resources of the two subsequent copies of UE1 is 4.
In step 320 of this embodiment, the access network device sends second PUSCH configuration information to the UE, where the second PUSCH configuration information is sent through RRC signaling, and the second PUSCH configuration information may include multiple sets of frequency hopping information, where each set of frequency hopping information is used to generate at least two replica time-frequency resources. For convenience of describing information carried in the frequency hopping information, information that may be carried in the frequency hopping information is divided into frequency domain resource information, time domain resource information, and DMRS resource information. It can be understood that the frequency domain resource information, the time domain resource information, and the DMRS resource information are only used to describe information that may be carried in the frequency hopping information, and it is not limited that the frequency domain resource information, the time domain resource information, and the DMRS resource information must be carried in the frequency hopping information at the same time.
(1) The frequency hopping information carries frequency domain resource information used for indicating to the UE to generate at least two copies of time frequency resources, that is, the frequency hopping information carries one of the following information:
a list of starting resource block offset values is provided,
a list of frequency-hopping offset values is displayed,
a list of hopping seeds.
(2) Optionally, the frequency hopping information may further carry time domain resource information used for indicating to the UE to generate at least two time frequency resources of the replica, that is, the frequency hopping information further includes at least one of the following information:
a list of starting symbol values is then generated,
a list of offset values for the starting time slot,
for the OFDM symbol length.
Optionally, because the persistent OFDM symbol lengths of the at least two replica time-frequency resources used for data repetition transmission on the time-domain resources are the same, the persistent OFDM symbol lengths may be carried in the second PUSCH configuration information in addition to the frequency hopping information, so as to reduce the signaling overhead.
In a possible embodiment, the access network device may indicate, to the UE, a repeat transmission type, where the repeat transmission type is used to indicate a time-domain relationship between multiple transmission time-frequency resources, that is, a repeat transmission type is carried in the frequency hopping information, and is used to indicate a relationship in a time domain between at least two duplicate time-frequency resources of the UE. The PUSCH repetition transmission type includes type-a and type-B, and the definition of type-a and type-B can refer to the foregoing explanation of the uplink URLLC repetition transmission process, and details are not described here.
It can be understood that the UE may determine, according to the time domain configuration information of the first time-frequency resource and the repeated transmission type configured by the access network device, time domain resource information between the first time-frequency resource and at least two replica time-frequency resources that the UE uses for PUSCH repeated transmission. It can be understood that, when the above-mentioned frequency hopping information carries a repeat transmission type, the access network device does not need to reconfigure other parameters of the time domain resource information for indicating at least two replica time frequency resources to the UE.
(3) Optionally, the frequency hopping information may further carry DMRS resource information used for indicating to the UE to generate at least two replica time-frequency resources, that is, the frequency hopping information further includes at least one of the following information: a list of DMRS offset values, a list of DMRS ports.
It may be understood that information included in each set of frequency hopping information may be used to generate at least two replica time-frequency resources, and if the frequency hopping information includes at least two of frequency domain resource information, time domain resource information, and DMRS configuration information used to generate the at least two replica time-frequency resources, the list lengths of the at least two information of the frequency domain resource information, the time domain resource information, and the DMRS configuration information may be the same or different, which is not limited in this embodiment of the present application. In the frequency hopping information, a scenario in which the list lengths of at least two kinds of information among the frequency domain resource information, the time domain resource information, and the DMRS configuration information are different is, for example, a frequency hopping offset value list in which a repeated transmission type, a list length L, and a DMRS offset value list in which a list length L are carried in the frequency hopping information. As another example, the hopping information carries a repeat transmission type and a hopping seed.
The frequency hopping information includes a scenario where list lengths of at least two information of frequency domain resource information, time domain resource information, and DMRS configuration information are the same, for example, each group of frequency hopping information includes (L-1) PUSCH time frequency resource configuration information, each PUSCH configuration information includes at least two information of the frequency domain resource information, the time domain resource information, and the DMRS configuration information, where the frequency domain resource information may be a starting resource block offset value, or a frequency hopping seed, the time domain resource information may include at least one information of a starting symbol value, a starting slot offset value, and a continuous OFDM symbol length, the DMRS configuration information may include a DMRS offset value, and at least one information of DMRS ports, and a value of (L-1) is the number of each group of frequency hopping information configured by the access network device.
It can be understood that the above example is only used to illustrate that the list lengths of at least two types of information, which are frequency domain resource information, time domain resource information, and DMRS configuration information carried in the frequency hopping information, may be the same or different, and the above example is not limited to the indication form determined for the frequency hopping information in the second PUSCH configuration information.
It can be understood that the above configuration information for generating the frequency domain resource information, the time domain resource information, and the DMRS in the at least two replica time-frequency resources is only used to illustrate parameters in the frequency hopping information when the access network device indicates to the UE to generate the at least two replica time-frequency resources, and does not limit names of the parameters in the frequency hopping information.
Optionally, the second PUSCH configuration information may include, in addition to the frequency hopping information, the following information: the number of times data is repeatedly transmitted. The number of times of data repeated transmission is used for indicating the number of the at least two duplicate time-frequency resources to the UE, or the number of times of data repeated transmission is used for indicating the total number of the first time-frequency resources and the at least two duplicate time-frequency resources to the UE.
It can be understood that the access network device sends the first PUSCH configuration information to the UE to indicate the first time-frequency resource, and sends the second PUSCH configuration information to indicate the frequency hopping information, where the sum of the lengths of the first time-frequency resource and the frequency hopping information is L, and the values of L and the number of times of data retransmission may be the same or different. The relationship between the two is exemplified in the following description when at least two replica time frequency resources are obtained.
In step 340 of the embodiment of the present application, the UE determines at least two replica time-frequency resources according to the first time-frequency resource and the second PUSCH configuration information, and the UE performs repeated data transmission through the first time-frequency resource and the at least two replica time-frequency resources. When the UE determines at least 2 replica time-frequency resources, at least one of a frequency domain resource, a time domain resource, and a DMRS resource of each replica time-frequency resource needs to be determined. Here, the determination method of the duplicate time-frequency resource is exemplified, and it can be understood that the determination method between the first time-frequency resource and the duplicate time-frequency resource in the following description is also applicable to the access network device, and the access network device generates the PUSCH time-frequency resource of each of the at least three UEs based on the determination method.
A. Frequency domain resource position of each copy time frequency resource in at least two copy time frequency resources
The UE determines the frequency domain resource of each copy time frequency resource, and mainly comprises the step of determining the frequency domain starting resource block index of each copy time frequency resource on a part of Bandwidth (BWP) of PUSCH time frequency resource used for uplink data transmission by the UE. The initial resource block index is determined according to the initial resource block index of the first time-frequency resource and the initial resource block offset value, and the initial resource block offset value is determined according to frequency hopping information in the second PUSCH configuration information.
In a possible implementation manner, the frequency hopping information carries a starting resource block offset value, and then an RB starting position of a frequency domain resource of an i-th replica time-frequency resource is: (RB) start +RB offset )modN BWP Wherein RB start Starting RB position of first time frequency resource, RB offset Relative RB of time-frequency resource of ith copy configured for access network equipment start Starting resource offset value of, N BWP And configuring the total number of resource blocks of the BWP where the PUSCH time-frequency resource used for uplink data transmission is located to the UE for the access network equipment.
In another possible implementation, the frequency hopping information carries a frequency hopping offset value, and then the RB starting position of the frequency domain resource of the ith copy time-frequency resource is:
Figure BDA0003071803190000121
wherein i is an integer greater than 0, RB start Frequency hop hopping offset, which is the starting RB position of the first time frequency resource, is a list of frequency hopping offset values configured by the access network equipment, and (L-1) is the length of the list of frequency hopping offset values, N BWP And configuring the total number of resource blocks of the BWP where the PUSCH time-frequency resource used for uplink data transmission is located to the UE for the access network equipment.
In another possible implementation, the frequency hopping information carries a frequency hopping seed, and the RB starting position of the frequency domain resource of the ith copy time-frequency resource is:
Figure BDA0003071803190000122
wherein i is an integer greater than 0, RB start Starting RB position, N, of the first time-frequency resource BWP The method comprises the steps that the total resource block number frequency HoppingSeed of BWP where PUSCH time-frequency resources used for uplink data transmission configured for UE by access network equipment are located is a value of a frequency hopping Seed configured for UE by the access network equipment, and f (k, seed) is a frequency hopping function and is used for obtaining an initial resource block offset value of the ith copy time-frequency resource relative to the first time-frequency resource according to the frequency hopping Seed. One possible expression of the hopping function f (k, seed) is as follows:
Figure BDA0003071803190000123
k = (i mod L), i mod L ≠ 0 wherein RB start,0 Configuring an initial value for the access network equipment to the UE for generating at least two copy time-frequency resources, seed is a frequency hopping Seed,
Figure BDA0003071803190000124
is the number of resource blocks of the frequency hopping granularity,
Figure BDA0003071803190000125
and A is the maximum frequency hopping number corresponding to the frequency hopping granularity and is the parameter of the frequency hopping function. For RB start,0
Figure BDA0003071803190000126
And a, may be predefined in the standard, or may be configured by the access network device to the UE through other RRC signaling, which is not limited in this embodiment of the present application.
In the embodiment of the present application, a method for generating frequency domain resources of at least two replica time frequency resources based on frequency hopping seeds is described as an example. For example, the access network device configures PUSCH time-frequency resources to the UEs 1 to 8, where the hopping seeds are respectively seed1 to seed8 corresponding to the UEs 1 to 8, and the parameters in the hopping function are respectively RB start,0 =0,
Figure BDA0003071803190000127
N BWP Where =4,l =1, the frequency domain resources of the at least two copies of the time-frequency resources of UE1 to UE8 are as shown in fig. 5 (b) based on the above frequency hopping function. Fig. 5 (a) is a schematic diagram of the locations of frequency domain resources of the first time-frequency resources of UE1 to UE 8. It can be understood that, in fig. 5, the first time-frequency resource of each of the UE1 to UE8 and the at least two duplicate time-frequency resources of the UE may not overlap in a frequency domain, and may also partially overlap, which is not limited in the embodiment of the present application.
It is to be understood that the above example is only illustrative of the method for generating frequency domain resources based on frequency hopping seeds, and is not limited to the overlapping pattern between PUSCH time frequency resources of at least three UEs, which may be generated by the above method.
B. Time domain resource position of each copy time frequency resource in at least two copy time frequency resources
If the frequency hopping information in the second PUSCH configuration information includes the configuration parameter for indicating the time domain resource, the UE may determine the time domain resource position of each replica time frequency resource according to the time domain resource of the first time frequency resource and the configuration parameter for indicating the time domain resource carried in the frequency hopping information.
In a possible implementation manner, the frequency hopping information includes a starting symbol value list and a starting timeslot offset value list, and the time domain resource position of the ith replica time frequency resource may be determined according to the starting timeslot index of the first time frequency resource, the starting symbol value list and the starting timeslot offset value list, and the specific expression may be:
(Slot start +startslotOffset(i))*m+Symbol start (i)
wherein, the Slot start The time slot index is a starting time slot index of a first time frequency resource, m represents a symbol length in one time slot, and a value of m is defined according to a predefined value set in a standard, which is not limited in the embodiment of the present application. startslotOffset (i) is a starting time slot offset value, symbol, configured by the access network equipment to the UE for determining the ith copy time-frequency resource start (i) And the access network equipment configures a starting symbol value for the UE for determining the ith copy time-frequency resource.
In another possible implementation, the frequency hopping information only includes a starting symbol value list, and the time domain resource position of the i-th replica time frequency resource may be determined according to the starting time slot index of the first time frequency resource and the starting symbol value list, and the specific expression may be:
(SlOt start +i)*m+Symbol start (i)
wherein, the Slot start The starting time slot index is the starting time slot index of the first time frequency resource, m represents the symbol length in one time slot, and the value of m is defined according to a predefined value set in the standard, which is not limited in the embodiment of the present application. Symbol start (i) And the starting symbol value is configured to the UE for the access network equipment to determine the ith copy time-frequency resource.
C. DMRS resource of each of at least two replica time frequency resources
If the frequency hopping information in the second PUSCH configuration information includes the configuration information corresponding to the DMRS resource, the UE may determine the DMRS resource on each replica time-frequency resource according to the configuration information used for indicating the DMRS resource in the frequency hopping information.
In a possible implementation manner, if the frequency hopping information contains the DMRS offset value list, when the UE determines the DMRS sequence on the ith copy time-frequency resource, the seed in the DMRS sequence is
Figure BDA0003071803190000131
Wherein dmrsfoffset (i) is a DMRS offset value corresponding to an i-th replica time-frequency resource in a DMRS offset value list configured for access network equipment,

Figure BDA0003071803190000133
the specific values of (a) are not limited in the embodiments of the present application, and reference may be made to the definition in the current standard protocol TR 38.211. For example, when the carrier is an OFDM waveform,

is taken as

Or alternatively

When the carrier is a DFT-S-OFDM waveform,
Figure BDA0003071803190000137
is taken as
Figure BDA0003071803190000138
In a possible implementation manner, if the frequency hopping information contains the DMRS port list, the UE determines to determine the DMRS port on the i-th replica time-frequency resource according to the corresponding DMRS port in the frequency hopping information.
The DMRS sequences or DMRS ports used by the UE for transmitting data on the first time frequency resource and the at least two copy time frequency resources are different, so that possible DMRS collision can be avoided when one UE and other UEs multiplex the same time frequency resources.
Based on the resource multiplexing transmission method described in the embodiment of the present application, the access network device receives data of the UE based on the configured PUSCH time-frequency resource. If the data of at least 2 UEs are received on the same PUSCH time-frequency resource, the access network equipment can eliminate the interference between different UEs by using the serial interference elimination SIC technology and decode the data of the UEs, thereby ensuring the transmission reliability of the UEs, reducing the PUSCH time-frequency resource overhead and improving the spectrum efficiency.
It can be understood that the resource multiplexing transmission method in the embodiment of the present application is not limited to uplink transmission of the URLLC service, and is applicable to other scenarios in which repeated transmission is required to ensure reliability of data transmission and improve spectrum efficiency as much as possible.
