Background

Radio access technology standards such as Long Term Evolution (LTE)/Long Term Evolution-enhanced (LTE-Advanced, LTE-a) are constructed based on Multiple-Input Multiple-Output (MIMO) technology and Orthogonal Frequency Division Multiplexing (OFDM) technology. The MIMO technology utilizes spatial freedom available in a multi-antenna system to improve peak rate and system spectrum utilization.

Referring to fig. 3, fig. 3 is a flowchart illustrating an information processing method according to an embodiment of the present disclosure.

The method can be applied to a terminal, and as shown in fig. 3, the method includes:

step S11, when the determined number of times of repeated transmission of a physical uplink shared channel PUSCH (physical uplink shared channel) is greater than or equal to 2 times, and the configured transmission configuration indicates that the TCI includes at least one first TCI and at least one second TCI, determining a mapping order of the TCIs when the PUSCH is repeatedly transmitted according to the configured PUSCH frequency hopping information or redundancy version RV information;

and step S12, sending PUSCH according to the determined mapping sequence of the TCI when the PUSCH is repeatedly transmitted.

Through the above method, the embodiment of the present disclosure may determine, according to configured PUSCH frequency hopping information or redundancy version RV information, a mapping order of TCIs when the PUSCH is repeatedly transmitted, when the number of repeated transmissions of the determined PUSCH is greater than or equal to 2 and the configured transmission configuration indication TCIs includes at least one first TCI and at least one second TCI, so that the embodiment of the present disclosure may determine the mapping order of the TCIs according to the PUSCH frequency hopping information or RV information without receiving a specific indication parameter of the TRP, and transmit the PUSCH according to the determined mapping order of the TCIs when the PUSCH is repeatedly transmitted.

In the related art, TRP indicates TCI mapping order through specific RRC parameters (e.g., cycmaping and SeqMapping parameters), namely, the terminal needs to determine the mapping sequence of the TCI when the PUSCH is repeatedly transmitted according to a specific RRC parameter, it can be seen that, when configuring the TCI mapping order, the related art needs to occupy additional transmission resources, and the terminal can not determine the mapping sequence of the TCI according to the adaptability of the actual communication scene, the flexibility is poor, however, the mapping sequence of the TCI during the repeated PUSCH transmission can be adaptively determined according to the PUSCH frequency hopping information or the RV information in the embodiments of the present disclosure, on one hand, the TRP does not need to display and indicate the mapping sequence of the TCI through a specific RRC parameter, thereby saving transmission resources, on the other hand, the terminal can adaptively determine the mapping sequence of the TCI according to an actual communication scenario, the method can adapt to the scene requirement, and increases the flexibility and the environmental adaptability, thereby improving the communication efficiency.

The present disclosure does not limit the information carried when the PUSCH is transmitted in step S12, and those skilled in the art can determine the information as needed.

Before describing a possible embodiment in which the mapping order of TCIs is determined when the PUSCH is repeatedly transmitted according to the configured PUSCH frequency hopping information or redundancy version RV information in step S11, for ease of understanding, first, an example of TRP configuration PUSCH repetition, PUSCH repeated transmission by a terminal, RV (redundancy version), frequency hopping, and the like is described.

In one example, the TRP may configure the number of repeated transmissions of the PUSCH in advance through a higher layer parameter, for example, may configure the number of repeated transmissions of the PUSCH through Radio Resource Control (RRC). Of course, the TRP may also indicate the number of repeated transmissions of the PUSCH by information in DCI (Downlink control information), and the disclosure is not limited thereto.

The TRP may configure the number of repeated transmissions of the PUSCH in different manners (PUSCH repetition types), and the terminal according to the embodiment of the disclosure may respond to the PUSCH repeated transmission manner according to the PUSCH repetition type configured by the TRP, which is exemplarily described below.

In one example, the TRP may configure PUSCH repetition types by RRC, which may include PUSCH repetition type a (PUSCH repetition type a) and PUSCH repetition type b (PUSCH repetition type b).

The PUSCH repetition type a may be a scheme of performing PUSCH repetition transmission in a Rel-15 scheme.

In the PUSCH repetition type a, the TRP may configure the number of PUSCH repetition transmissions by a higher layer parameter PUSCH-aggregation factor parameter. Since the Time Domain Resource Allocation (TDRA) table is introduced into Rel-16, in the PUSCH repetition type a, the TRP may also dynamically indicate the PUSCH repetition transmission times by using the table of the TDRA. If the TDRA table contains the PUSCH retransmission times, the terminal may preferably use the PUSCH retransmission times indicated in the TDRA, if the TDRA table does not contain the PUSCH retransmission times, the terminal may use the number of times configured by the high-level parameter PUSCH-aggregation factor, and if neither of the above is configured, the terminal defaults to 1 PUSCH retransmission times.

In PUSCH repetition type a, the TRP may indicate the time domain position of the first PUSCH repetition transmission through the TDRA table, and the time domain positions of the subsequent transmission in each slot and the transmission in the first slot are identical.

The PUSCH repetition type B may be PUSCH repetition transmission performed in a Rel16 manner.

In PUSCH repetition type B, the TRP may indicate a nominal (nominal) number of PUSCH repetitions transmitted by the terminal through the TDRA table, which "nominal" may be the number of PUSCH repetitions transmitted by the TRP intended for the terminal, as opposed to an actual number of transmissions, which in one example may be greater than 1 if the nominal number of PUSCH repetitions indicated by the TRP is 1.

When the terminal needs to perform PUSCH retransmission, the actual PUSCH retransmission situation (number of times, etc.) may be determined according to the actual situation, and exemplary description is given below for the PUSCH retransmission.

Referring to fig. 4, fig. 4 shows a schematic diagram of PUSCH repeated transmission according to an embodiment of the present disclosure.

In one possible implementation, as shown in fig. 4, S denotes the position of the start (3 rd OFDM symbol), K denotes the repetition 2 times, L denotes the length of each nominal transmission (6 OFDM symbols), and RV denotes the redundancy version (redundancy).

In one possible implementation, as shown in fig. 4, the PUSCH repeated transmission indicated by the TRP is 2 nominal transmissions (nominal repetition 1, nominal repetition 2), and for the nominal repetition 2, when the terminal encounters a downlink symbol (DL) during actual transmission, the terminal will split the 1 nominal transmission into two actual transmissions, and when a slot boundary (slot boundary) is crossed, the terminal will also split into two actual transmissions, so that the nominal repetition 2 corresponds to 3 actual PUSCH repeated transmissions.

In one possible embodiment, as shown in fig. 4, the TRP may indicate a corresponding redundancy version in PUSCH repeated transmission, and assuming that RV information indicated by the TRP is (RV0, RV2, RV3, RV1), the terminal associates each RV with each PUSCH repeated transmission in actual PUSCH repeated transmission, for example, PUSCH repeated transmission in nominal repetition 1 is performed by RV0, first actual PUSCH repeated transmission in nominal repetition 2 is performed by RV2, second actual PUSCH repeated transmission in nominal repetition 2 is performed by RV3, and third actual PUSCH repeated transmission in nominal repetition 2 is performed by RV 1. The RV may be configured to encode information to be transmitted when the PUSCH is repeatedly transmitted, where different RVs indicate different encoding modes.

When the terminal performs PUSCH repeated transmission, it needs to encode the transmitted information with an RV, which is exemplarily described below.

Referring to fig. 5, fig. 5 is a diagram illustrating determination of RV versions according to an embodiment of the present disclosure.

As shown in fig. 5, for the PUSCH repetition type a, the TRP may indicate an RV corresponding to PUSCH transmission through a codeword (n) indicating transmission in an RV domain in DCI, and when the terminal receives the DCI, the terminal may obtain the corresponding RV by using the codeword n in the RV domain, for example, assuming that n is 11, the terminal may determine that a first PUSCH repetition transmission corresponds to RV3, a second PUSCH repetition transmission corresponds to RV1, a third PUSCH repetition transmission corresponds to RV0, and a fourth PUSCH repetition transmission corresponds to RV 2.

Of course, the TRP may also be configured by RRC with RV sequence (RV sequence), for example, for PUSCH repeated transmission of a schedule-exempt (configuration grant), the TRP may be configured by RRC with RV sequence as one of s1{ RV0, RV2, RV3, RV1}, s2{ RV0, RV3, RV0, RV3}, s3{ RV0, RV0, RV0, RV0 }.

For PUSCH repetition type B, the TRP may indicate via DCI the RV of the first actual PUSCH repetition transmission, for scheduling-free transmission, whether the RV sequence is indicated via higher layer parameters, for RV sequence S2 and RV sequence S3, whether the TRP determines via higher layer parameters whether the first transmission opportunity (occasting) starts from the first RV0 (S2 and S3 include multiple RVs 0, the TRP may indicate whether to encode information starting from the first RV 0).

An exemplary PUSCH frequency hopping (PUSCH frequency hopping) is described below.

For the PUSCH repetition type a, the TRP may configure the frequency hopping mode during PUSCH repetition transmission as intra-slot frequency hopping (intra-slot frequency hopping) or inter-slot frequency hopping (inter-slot frequency hopping).

In one example, when the TRP is configured to hop in a frequency hopping manner between slots and the terminal is performing PUSCH repeated transmission, the terminal may hop in different slots, such as frequency domain position 1 in slot0/2/4/6 … … and frequency domain position 2 in slot1/3/5/7 … ….

In one example, when a TRP configures a frequency hopping manner to frequency hopping within a slot, and a terminal performs PUSCH repeated transmission, the terminal may frequency hop within each slot, where a symbol corresponding to a first hop is

(integer removed), the symbol corresponding to the second hop is

(taking the upper integer), wherein N is the number of symbols in the time domain of one transmission.

For the PUSCH repetition type B, the TRP may configure the frequency hopping mode when the PUSCH is repeatedly transmitted as inter-PUSCH frequency hopping (inter-PUSCH frequency hopping) or inter-slot frequency hopping (inter-slot frequency hopping).

In one example, inter-PUSCH frequency hopping may include a first inter-PUSCH frequency hopping pattern and a second inter-PUSCH frequency hopping pattern.

Referring to fig. 6a and 6b, fig. 6a shows a schematic diagram of first inter-PUSCH frequency hopping according to an embodiment of the present disclosure, and fig. 6b shows a schematic diagram of second inter-PUSCH frequency hopping according to an embodiment of the present disclosure.

Fig. 6a shows that the first inter-PUSCH frequency hopping pattern may be a frequency hopping pattern of nominal PUSCH repetition, where in the first inter-PUSCH frequency hopping pattern, first hop PUSCH repeated transmission (nominal PUSCH repeated transmission rep.1) corresponding to the first 10 symbols is at a frequency domain position of the first hop, and second hop PUSCH repeated transmission (nominal PUSCH repeated transmission rep.2) corresponding to the last 10 symbols is at a frequency domain position of the second hop. For example, the first-hop repeated PUSCH transmission may be divided into rep.1-1 and rep.1-2, and the second-hop repeated PUSCH transmission may be divided into rep.2-1 and rep.2-2, but the frequency is not hopped in each-hop repeated PUSCH transmission (the frequency domain positions of rep.1-1 and rep.1-2 are the same, and the frequency domain positions of rep.2-1 and rep.2-2 are the same), and only hopping between nominal PUSCHs (the frequency is hopped between the first-hop repeated PUSCH transmission and the second-hop repeated PUSCH transmission)

Fig. 6b shows that the second inter-PUSCH frequency hopping pattern may be an actual inter-PUSCH repetition (inter actual PUSCH repetition), where in the second inter-PUSCH frequency hopping pattern, the first 10 symbols correspond to two actual PUSCH repeated transmissions (rep.1-1 and rep.1-2), and the second 10 symbols correspond to two actual PUSCH repeated transmissions (rep.2-1 and rep.2-2). In the second inter-PUSCH frequency hopping manner, the frequency domain positions corresponding to each actual PUSCH repeated transmission are different (the frequency domain positions corresponding to the actual PUSCH repeated transmissions of rep.1-1, rep.1-2, rep.2-1 and rep.2-2 are all different).

The determining of the mapping order of the TCIs during the PUSCH repeated transmission according to the configured PUSCH frequency hopping information or redundancy version RV information in the embodiments of the present disclosure may be implemented in various ways, which is described below as an example.

In a possible implementation manner, when the determined number of repetitions of the PUSCH is greater than 2, the step S11 determines the mapping order of the TCIs in the PUSCH repeated transmission according to the configured PUSCH frequency hopping information or redundancy version RV information, and may include:

if the configured PUSCH repetition mode is a first repetition mode (PUSCH repetition type a), and if the frequency hopping mode indicated by the PUSCH frequency hopping information is one of no frequency hopping (or referred to as frequency hopping disabling) and frequency hopping within a time slot (intra-slot frequency hopping), determining that the mapping order of the TCIs a first TCI, a second TCI, and a second TCI when the PUSCH is repeatedly transmitted; or

In one example, the TRP may configure PUSCH hopping information with higher layer parameters.

In an example, the TRP may configure the nominal PUSCH retransmission times in a manner of a higher layer parameter or DCI, and the terminal may determine the actual PUSCH retransmission times according to the PUSCH retransmission times configured by the TRP, an actual time-frequency resource, and a communication environment.

In one example, as shown in fig. 4, when the TRP indicates PUSCH retransmission as nominal repetition 2, but the terminal determines that a downlink symbol DL, or slot boundary, is encountered at PUSCH retransmission, the nominal PUSCH retransmission may be sliced into multiple actual PUSCH retransmissions (fig. 4 shows that nominal repetition 2 is sliced into 3 actual PUSCH retransmissions).

In an example, assuming that the actually determined number of times of PUSCH retransmission is 4, if the configured PUSCH repetition mode is the first repetition mode (PUSCH repetition type a), and the frequency hopping mode indicated by the PUSCH frequency hopping information is one of no frequency hopping (or referred to as frequency hopping de-enabling) and frequency hopping within a time slot (intra-slot frequency hopping), the embodiment of the present disclosure may configure 4 times of PUSCH retransmission to be mapped with the first TCI, the second TCI, and the second TCI in sequence (fig. 7a), that is, the beam direction of the first PUSCH retransmission is determined according to the first TCI, the beam direction of the second PUSCH retransmission is determined according to the first TCI, and the beam directions of the third and fourth PUSCH retransmission are both determined according to the second TCI.

In an example, assuming that the actually determined number of times of PUSCH repetition transmission is greater than 4 times, for example, 8 times, if the configured PUSCH repetition mode is the first repetition mode (PUSCH repetition type a), and the frequency hopping mode indicated by the PUSCH frequency hopping information is one of no frequency hopping (or referred to as frequency hopping disabling) and frequency hopping within a time slot (intra-slot frequency hopping), the embodiment of the present disclosure may configure that the TCIs of the 8 times of PUSCH repetition transmission are repeated in an order of the first TCI, the second TCI, and the second TCI, that is, the beam directions of the first to fourth times of PUSCH repetition transmission are determined in order according to the first TCI, the second TCI, and the second TCI, respectively, and the beam directions of the fifth to eighth times of PUSCH repetition transmission are determined in order according to the first TCI, the second TCI, and the second TCI, respectively.

Referring to fig. 7a and 7b, fig. 7a and 7b are schematic diagrams illustrating an association manner of TCI and PUSCH repeated transmission.

When the multi-TRP is used at the edge of a cell, since the TRP does not configure a large bandwidth for one transmission in this case, the disclosed embodiment configures different frequency bands for different TRPs, and therefore, the disclosed embodiment implements association of TCI and actual PUSCH repeated transmission in the manner of fig. 7b, that is, in consecutive time slots (different PUSCH repeated transmissions), TCI employs an interval repeated configuration manner (TCI1, TCI2, TCI1, TCI2 …).

By the above manner, when the multi-TRP is used at the edge of the cell, since the TRP does not configure a large bandwidth for one-time PUSCH repeated transmission in this case, the embodiment of the present disclosure configures different frequency bands for different TRPs, thereby implementing reliable transmission of the PUSCH and ensuring accuracy of communication.

Of course, in other embodiments, in order to reduce the number of beam switching to speed up the transmission process, the embodiments of the present disclosure may also adopt an association manner as shown in fig. 7a, that is, in consecutive slots (different PUSCH repeat transmissions), the TCI adopts an interval repeat configuration manner (TCI1, TCI1, TCI2, and TCI2 …).

As shown in fig. 7a, in the above case, the mapping order of TCIs is the first TCI (TCI1), the first TCI (TCI1), the second TCI (TCI2), the second TCI (TCI2) when PUSCH is repeatedly transmitted.

Through the above method, the embodiment of the present disclosure may quickly determine the mapping order of the TCI during repeated transmission of the PUSCH when the frequency hopping manner indicated by the PUSCH frequency hopping information is frequency hopping within a time slot without frequency hopping, and may avoid a behavior that a terminal frequently switches a beam direction (beam) or switches an antenna panel (panel).

In an example, assuming that the actually determined number of PUSCH repeated transmissions is 4, if the configured PUSCH repeated transmission is the first repeated transmission, and the frequency hopping manner indicated by the PUSCH frequency hopping information is frequency hopping between slots, the embodiment of the present disclosure may configure that the 4 PUSCH repeated transmissions are sequentially mapped with the first TCI, the second TCI, the first TCI, and the second TCI (fig. 7b), that is, the beam direction of the first PUSCH repeated transmission is determined according to the first TCI, the beam direction of the second PUSCH repeated transmission is determined according to the second TCI, the beam direction of the third PUSCH repeated transmission is determined according to the first TCI, and the beam direction of the fourth PUSCH repeated transmission is determined according to the second TCI.

In an example, assuming that the actually determined number of PUSCH repeated transmissions is greater than 4 times, for example, 8 times, if the configured PUSCH repeated transmission mode is the first repeated mode, and the frequency hopping mode indicated by the PUSCH frequency hopping information is frequency hopping among slots, the embodiments of the present disclosure may configure the TCI of the PUSCH repeated transmission 8 times to be repeated in the order of the first TCI, the second TCI, the first TCI, and the second TCI, that is, the beam direction of the PUSCH repeated transmission from the first time to the fourth time is determined sequentially and respectively according to the first TCI, the second TCI, the first TCI, and the second TCI, and the beam direction of the PUSCH repeated transmission from the fifth time to the eighth time is determined sequentially and respectively according to the first TCI, the second TCI, the first TCI, and the second TCI.

In one example, each TCI may correspond to each slot (slot) or may correspond to a repeated transmission occasion (PUSCH occasting) on each PUSCH.

Through the above method, the embodiment of the present disclosure may quickly determine the mapping order of the TCI during PUSCH retransmission when the configured PUSCH repetition mode is the first repetition mode and the frequency hopping mode indicated by the PUSCH frequency hopping information is inter-slot frequency hopping, and perform frequency hopping on PUSCH retransmission of one TRP without performing frequency hopping and PUSCH retransmission between different TRPs, thereby improving communication efficiency.

if the configured PUSCH repetition mode is a second repetition mode (PUSCH repetition type B), and the frequency hopping mode indicated by the PUSCH frequency hopping information is not frequency hopping, determining that the order of TCI mapping when the PUSCH is repeatedly transmitted is a first TCI, a second TCI, and a second TCI; or

In one example, in the mapping order of TCIs at PUSCH repetition transmission determined in case that the configured PUSCH repetition mode is the second repetition mode, each TCI may correspond to an actual PUSCH repetition transmission, and may also correspond to a nominal PUSCH repetition transmission.

In an example, assuming that the actually determined number of PUSCH repeated transmissions is 4, if the configured PUSCH repeated transmission mode is the second repeated mode (PUSCH repeated type B), and the frequency hopping mode indicated by the PUSCH frequency hopping information is not frequency hopping, the embodiment of the present disclosure may configure 4 PUSCH repeated transmissions to be sequentially mapped with the first TCI, the second TCI, and the second TCI (as shown in fig. 7a), that is, the beam direction of the first PUSCH repeated transmission is determined according to the first TCI, the beam direction of the second PUSCH repeated transmission is determined according to the first TCI, and the beam directions of the third and fourth PUSCH repeated transmissions are both determined according to the second TCI.

In an example, assuming that the actually determined number of PUSCH repeated transmissions is greater than 4 times, for example, 8 times, if the configured PUSCH repetition mode is the second repetition mode (PUSCH repetition type B), and if the frequency hopping mode indicated by the PUSCH frequency hopping information is not frequency hopping, the embodiments of the present disclosure may configure that the TCI of the PUSCH repeated transmissions is repeated in the order of the first TCI, the second TCI, and the second TCI, that is, the beam directions of the PUSCH repeated transmissions for the first time to the fourth time are sequentially and respectively determined according to the first TCI, the second TCI, and the beam directions of the PUSCH repeated transmissions for the fifth time to the eighth time are sequentially and respectively determined according to the first TCI, the second TCI, and the second TCI.

Through the above method, the embodiment of the present disclosure may quickly determine the mapping sequence of the TCIs during the PUSCH retransmission when the configured PUSCH repetition mode is the second repetition mode (PUSCH repetition type B) and the frequency hopping mode indicated by the PUSCH frequency hopping information is no frequency hopping, and through the above configuration, the embodiment of the present disclosure may avoid introducing a gap (gap) between different TCIs, and may avoid a behavior that the terminal frequently switches the beam direction or switches the antenna panel.

In a possible implementation manner, in a case that the determined number of repetitions of the PUSCH is greater than 2 and the corresponding nominal PUSCH repetition transmission is 2, the step S11 determining the mapping order of the TCIs in the PUSCH repetition transmission according to the configured PUSCH frequency hopping information or redundancy version RV information may include:

In one example, the TCI may correspond in a nominal PUSCH repetition transmission.

In one example, assuming that the actually determined PUSCH repetition transmission is 4 times and corresponds to two nominal PUSCH repetition transmissions, for example, two nominal PUSCH repetition transmissions, each of which includes 2 actually determined PUSCH repetition transmissions, the mapping order of TCIs the first TCI and the second TCI, that is, the first nominal PUSCH repetition transmission may determine the beam direction through the first TCI, the second nominal PUSCH repetition transmission may determine the beam direction through the second TCI, and the corresponding 4 actual PUSCH repetition transmissions may determine the beam direction according to the first TCI, the second TCI, and the second TCI, respectively.

Through the above method, the PUSCH repetition mode that can be configured in the embodiment of the present disclosure is the second repetition mode, and when the frequency hopping mode indicated by the PUSCH frequency hopping information is not frequency hopping, it is determined that the order of TCI mapping when the PUSCH is repeatedly transmitted is the first TCI and the second TCI, thereby improving communication efficiency.

if the configured PUSCH repetition mode is the second repetition mode, and the frequency hopping mode indicated by the PUSCH frequency hopping information is inter-slot frequency hopping (inter-slot frequency hopping) or inter-PUSCH frequency hopping (inter-puschhfrequency hopping), determining that the mapping order of the TCIs the first TCI, the second TCI, the first TCI, and the second TCI when the PUSCH is repeatedly transmitted; or

In one example, assuming that the actually determined number of times of PUSCH repeated transmission is 4, the configured PUSCH repetition mode is a second repetition mode, and in a case that the frequency hopping mode indicated by the PUSCH frequency hopping information is inter-slot frequency hopping (inter-slot frequency hopping) or inter-PUSCH frequency hopping (inter-PUSCH frequency hopping), the disclosed embodiment may configure 4 times of PUSCH repeated transmission to be mapped with a first TCI, a second TCI, a first TCI, and a second TCI in sequence (as shown in fig. 7b), that is, a beam direction of the first PUSCH repeated transmission is determined according to the first TCI, a beam direction of the second PUSCH repeated transmission is determined according to the second TCI, a beam direction of the third PUSCH repeated transmission is determined according to the first TCI, and a beam direction of the fourth repeated transmission is determined according to the second TCI.

In one example, assuming that the actually determined number of times of PUSCH repeated transmission is greater than 4 times, for example, 8 times, the configured PUSCH repetition mode is the second repetition mode, and in a case that the frequency hopping mode indicated by the PUSCH frequency hopping information is inter-slot frequency hopping (inter-slot frequency hopping) or inter-PUSCH frequency hopping (inter-PUSCH frequency hopping), the embodiments of the present disclosure may configure that the TCIs of the 8 times of PUSCH repeated transmission are repeated in an order of the first TCI, the second TCI, the first TCI, and the second TCI, that is, the beam directions of the first to fourth times of PUSCH repeated transmission are determined in order according to the first TCI, the second TCI, the first TCI, and the second TCI, respectively, and the beam directions of the fifth to eighth times of PUSCH repeated transmission are determined in order according to the first TCI, the second TCI, the first TCI, and the second TCI, respectively.

In one example, in a case that the frequency hopping manner indicated by the PUSCH frequency hopping information is inter-slot frequency hopping, each TCI corresponds to all PUSCH repeated transmissions in each slot.

In one example, the inter-PUSCH frequency hopping includes a first inter-PUSCH frequency hopping and a second inter-PUSCH frequency hopping, wherein,

when the frequency hopping mode indicated by the PUSCH frequency hopping information is first inter-PUSCH frequency hopping, each TCI corresponds to nominal PUSCH repeated transmission corresponding to the first inter-PUSCH frequency hopping;

in one example, as shown in fig. 6a, with reference to the previous description of fig. 6a, frequency hopping is performed between the nominal PUSCHs (rep.1 and rep.2), indicating that the frequency domain locations of the TRP-defined two repeated transmissions of the nominal PUSCH are different, in which case the first TCI is mapped to rep.1 and the second TCI is mapped to rep.2.

In one example, as shown in fig. 6b, referring to the previous description of fig. 6b, the actual PUSCH repetition transmission may indicate that the nominal PUSCH repetition transmission indicated by the TRP is divided into two transmissions, e.g., rep.1 times divided into rep.1-1 and rep.1-2, and the frequency domain locations of the two repeated transmissions are different (frequency hopping).

Assuming that the TCI mapping sequence is a first TCI, a second TCI, a first TCI and a second TCI, the first TCI can be mapped at Rep.1-1, the second TCI can be mapped at Rep.1-2, the first TCI can be mapped at Rep.2-1, and the second TCI can be mapped at Rep.2-2.

Through the above method, the PUSCH repetition mode that may be configured in the embodiment of the present disclosure is the second repetition mode, and when the frequency hopping mode indicated by the PUSCH frequency hopping information is inter-slot frequency hopping or inter-PUSCH frequency hopping, the mapping order of the TCIs quickly determined when the PUSCH is repeatedly transmitted, and frequency hopping is not performed for PUSCH repetition transmission of one TRP, and PUSCH repetition transmission between different TRPs is repeatedly frequency hopped, thereby improving communication efficiency.

In a possible implementation manner, in the case that the determined number of repetitions of the PUSCH is 2, the step S11 determining the mapping order when the PUSCH is repeatedly transmitted according to the configured PUSCH frequency hopping information or redundancy version RV information may include:

In one example, if the actually determined PUSCH repetition number is 2, the terminal may directly determine that the beam direction is determined by the first TCI for the first PUSCH repetition transmission and the beam direction is determined by the second TCI for the second PUSCH repetition transmission.

Through the above method, the embodiment of the disclosure can quickly determine the mapping order of the TCIs during repeated transmission of the PUSCH under the condition that the determined repetition number of the PUSCH is 2, thereby improving communication efficiency.

The above describes determining the mapping order of TCIs in PUSCH repeated transmission by using PUSCH hopping information, and the following describes a possible embodiment of determining the mapping order of TCIs in PUSCH repeated transmission by using RV information.

In one example, if the TRP schedules PUSCH repeated transmission based on a dynamic scheduling manner, the RV information may be { RV0, RV2, RV3, RV1}, in which case, if the PUSCH repeated transmission number is 4 or more, the PUSCH repeated transmission determines the beam direction sequentially through the first TCI, the second TCI, and the second TCI (the beam direction is repeated more than 4 times).

Through the above method, the embodiment of the present disclosure may determine the mapping sequence of the TCI when the PUSCH is repeatedly transmitted, where the PUSCH is repeatedly transmitted based on a dynamic scheduling manner.

In one example, RV0 and RV3 both include system information, and therefore independent decoding may be achieved, and therefore, for { RV0, RV2, RV3, RV1}, embodiments of the present disclosure may configure RV versions of RV0 and RV3 corresponding to first PUSCH repeated transmissions of different TRPs.

In one example, in order to enable the same TRP to use different RV versions, there may be a gain of soft combining, an embodiment of the present disclosure corresponds the first two RV0 and RV3 in { RV0, RV3, RV0, RV3} to a first TCI, and the second two RV0 and RV3 to a second TCI.

Through the method, the mapping sequence of the TCI during the repeated transmission of the PUSCH can be determined according to the configured different RV information, so that the method and the device are suitable for different communication environments, and the flexibility is improved.

Referring to fig. 8, fig. 8 is a flowchart illustrating an information receiving method according to an embodiment of the present disclosure.

The method is applied to transmitting a reception point TRP, as shown in FIG. 8, and comprises the following steps:

step S21, receiving PUSCH repeated transmission according to a mapping sequence of TCIs during PUSCH repeated transmission of a physical uplink shared channel, wherein the mapping sequence of TCIs determined according to configured PUSCH frequency hopping information or redundancy version, RV information when the determined number of repeated transmission of PUSCH is greater than or equal to 2 and the configured transmission configuration indicates that the TCIs includes at least one first TCI and at least one second TCI.

Through the above method, the embodiment of the present disclosure may receive the PUSCH repeated transmission according to the mapping order of the TCIs during the PUSCH repeated transmission determined by the configured PUSCH frequency hopping information or redundancy version RV information, when the determined number of repeated transmissions of the PUSCH is greater than or equal to 2 times and the configured transmission configuration indication TCI includes at least one first TCI and at least one second TCI, thereby quickly receiving the PUSCH repeated transmission and improving communication efficiency.

In one example, the multiple TRPs may include a first TRP and a second TRP, wherein the first TRP receives a PUSCH repeated transmission with a first TCI, the second TRP receives a PUSCH repeated transmission with the first TCI, then the first TRP may receive a PUSCH repeated transmission with a second TCI, and the second TRP may receive a PUSCH repeated transmission with the second TCI.

In one example, a first TRP may receive a PUSCH repeated transmission with a first TCI, a second TRP may receive a PUSCH repeated transmission with a second TCI, and then the first TRP may receive the PUSCH repeated transmission with the first TCI and the second TRP may receive the PUSCH repeated transmission with the second TCI.
