Description

Technical Field

[0001] The present application relates to the field of wireless communications, and in particular to an uplink channel transmission method, apparatus, device, and storage medium. Background Art

[0002] 3GPP (3rd Generation Partnership Project) introduced a collaborative transmission technology based on multiple TRPs (Transmit-Receive Points) in the 5G (5th-Generation Mobile Communication Technology) NR (New Radio) system.

[0003] In the discussion of R17 (Release 17), a collaborative transmission technology based on multiple TRPs has certain implementation advantages, namely the intra-slot beam hopping scheme. The intra-slot beam hopping scheme is based on the intra-slot frequency hopping scheme, and it is recommended to use different transmission beams for different frequency hopping resources. That is, for the time slot used for PUSCH (Physical Uplink Shared Channel) transmission, the terminal device transmits PUSCH to different TRPs of the same network device on different frequency hopping resources within the time slot. As a result, the terminal device can obtain beam diversity gain within the time slot, and since the intra-slot beam hopping scheme is based on the intra-slot frequency hopping scheme, the complexity of the terminal device to implement the intra-slot beam hopping scheme will also be lower.

[0004] However, in the above-mentioned intra-time slot beam hopping scheme, the terminal device sends PUSCH to different TRPs of the network device through the collaboration of different frequency hopping resources within the time slot, and does not repeatedly transmit PUSCH on multiple frequency hopping resources within the time slot. Therefore, the transmission reliability of PUSCH is low, and it is difficult to combat the performance deterioration in congestion and deep fading conditions. Summary of the Invention

[0005] The embodiments of the present disclosure provide an uplink channel transmission method, apparatus, device, and readable storage medium that can improve PUSCH transmission reliability, effectively combat performance degradation in congestion and deep fading conditions, and more flexibly adapt to service requirements with different latency and performance.

[0027] The beneficial effects of the technical solutions provided by the embodiments of the present disclosure include at least:

This can effectively combat performance deterioration in congestion and deep fading conditions, and achieve more flexible adaptation to service requirements with different delays and performance.

[0047] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0048] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings.

These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information.

[0051] 3GPP introduced collaborative transmission technology based on multiple TRPs in the 5G NR system. The application of multiple TRPs / Panels (antenna panels) in network equipment is mainly to improve coverage at the cell edge, provide more balanced service quality within the service area, and coordinate data transmission between multiple TRPs / Panels in different ways. From the perspective of network morphology, network deployment with a large number of distributed access points plus centralized baseband processing will be more conducive to providing a balanced user experience rate and significantly reduce the latency and signaling overhead caused by handover. By utilizing the collaboration between multiple TRPs / Panels and transmitting / receiving channels from multiple beams in multiple directions, various shading / blocking effects can be better overcome, ensuring the robustness of link connections. This is suitable for URLLC (Ultra Reliable Low Latency Communication) services to improve transmission quality and meet reliability requirements.

[0052] During the R16 (Release 16) research phase, the application of collaborative transmission technology based on multiple TRPs mainly enhanced the transmission of PDSCH (Physical Downlink Shared Channel). Since data transmission includes scheduling feedback of uplink and downlink channels, in the URLLC research, only enhancing the downlink data channel cannot guarantee service performance. Therefore, the discussion in R17 continued to enhance PDCCH (Physical Downlink Control Channel), PUCCH (Physical Uplink Control Channel), and PUSCH.

[0053] The multi-TRP uplink enhancement scheme discussed in Release 17 is primarily based on the PUSCH repetition scheme introduced in Release 16. For scheduled PUSCHs, there are two main PUSCH time-domain repetition enhancement methods: repetition type A and repetition type B, introduced in Release 16.

[0054] 1. PUSCH repetition type A transmission mode.

[0055] R16's slot-level Slot Aggregation PUSCH transmission is suitable for situations where latency requirements are very low and reliability is very high. A PUSCH is transmitted in K consecutive slots (K is a positive integer), i.e., K Transmission Occasions (TO), starting at the Sth symbol (S is greater than or equal to 0) in the starting slot. Each transmission opportunity lasts for L symbols (L is a positive integer), and S + L cannot exceed the slot boundary.

[0056] For example, Figure 1 As shown, K is equal to 2, S is equal to 4, and L is equal to 4. The terminal device performs the first repetition transmission from the 4th symbol to the 7th symbol in the first time slot, and performs the second repetition transmission from the 4th symbol to the 7th symbol in the second time slot. Optionally, a time slot includes 14 symbols, namely the 0th symbol to the 13th symbol.

[0057] 2. PUSCH repetition type B transmission mode.

[0058] In order to reduce latency and improve reliability, R16 supports PUSCH repetition transmission schemes in Mini-slot units, and allows PUSCH transmissions to cross time slots to further reduce latency. In the time domain, a PUSCH starts transmission at the Sth symbol in the starting time slot, and sends K transmission opportunities continuously. Each transmission opportunity occupies L symbols continuously, and S+L can cross time slot boundaries. In the case where the transmission opportunity crosses the time slot boundary, the transmission will be re-divided. For the entire transmission, L*K represents the time window length of the PUSCH transmission. DL (Downlink) symbols and other invalid symbols will be discarded and not used for PUSCH transmission.

[0059] For example, Figure 2 As shown, K is equal to 2, S is equal to 4, and L is equal to 4. The terminal device performs the first repetition transmission from the 4th symbol to the 7th symbol of the first time slot, and performs the second repetition transmission from the 8th symbol to the 11th symbol of the first time slot. Optionally, one time slot includes 14 symbols, namely the 0th symbol to the 13th symbol.

[0060] For example, Figure 3As shown, K is equal to 4, S is equal to 4, and L is equal to 4. The terminal device performs the first repeated transmission from the 4th symbol to the 7th symbol of the first time slot, and performs the second repeated transmission from the 8th symbol to the 11th symbol of the first time slot. Since according to the configuration information, the 4 symbols of the third repeated transmission cross the time slot boundary of the first time slot, the third repeated transmission is divided into two repeated transmissions, and the third repeated transmission is performed from the 12th symbol to the 13th symbol of the first time slot, and the fourth repeated transmission is performed from the 1st symbol to the 2nd symbol of the second time slot. The fifth repeated transmission is performed from the 3rd symbol to the 7th symbol of the second time slot. That is, the terminal device actually performs 5 repeated transmissions, and each repeated transmission sends the same data. Optionally, a time slot includes 14 symbols, namely the 0th symbol to the 13th symbol.

[0061] For example, Figure 4 As shown, K is equal to 1, S is equal to 4, and L is equal to 14. Since the length of a time slot is 14 symbols, the transmission starts from the 4th symbol of the starting time slot, and each transmission opportunity occupies 14 symbols, then the 14 symbols of the first repeated transmission will cross the time slot boundary, and the first repeated transmission will be divided into two repeated transmissions. The first repeated transmission is performed from the 4th symbol to the 13th symbol of the first time slot, and the second repeated transmission is performed from the 1st symbol to the 4th symbol of the second time slot. That is, the terminal device actually performs 2 repeated transmissions, and each repeated transmission sends the same data. Optionally, a time slot includes 14 symbols, namely the 0th symbol to the 13th symbol.

[0062] In the R17 multi-TRP enhancement, PUSCH supports sending the same transport block (TB) to different TRPs at different transmission opportunities under the transmission mode defined above, further applying spatial multiplexing to improve transmission reliability. The enhancement schemes currently under discussion mainly include: multi-TRP scheme based on repetition type A and multi-TRP scheme based on repetition type B.

[0063] Among them, there are multiple mapping schemes that can be considered for the mapping relationship between the beam transmission direction of PUCCH / PUSCH sent by the terminal device for different TRPs and different transmission times. The following are three typical schemes.

[0064] Solution a: Periodic mapping. Two beam directions are cyclically mapped to multiple configured transmission opportunities. For example, when performing four repeated transmissions, the beam direction mapping pattern might be #1#2#1#2, where #1 corresponds to the first beam direction and #2 corresponds to the second beam direction.

[0065] Solution b: Continuous mapping. Two beam directions are mapped to multiple configured transmission opportunities in a continuous cycle. For example, for four repeated transmissions, the beam direction mapping pattern might be #1#1#2#2. For more than four repeated transmissions, this pattern is repeated. For example, for eight repeated transmissions, the beam direction mapping pattern might be #1#1#2#2#1#1#2#2. #1 corresponds to the first beam direction, and #2 corresponds to the second beam direction.

[0066] Solution c: Half-and-half mapping. Two beam directions are consecutively mapped to multiple configured transmission opportunities. For example, when performing eight repeated transmissions, the beam direction mapping pattern might be #1#1#1#1#2#2#2#2, where #1 corresponds to the first beam direction and #2 corresponds to the second beam direction.

[0067] During the R17 discussion, a collaborative transmission technology based on multiple TRPs was proposed, demonstrating certain implementation advantages: intra-slot beam hopping. This approach builds upon the intra-slot frequency hopping approach and recommends using different transmit beams for different frequency hopping resources. Specifically, for a timeslot used for PUSCH transmission, a terminal device transmits PUSCH on different frequency hopping resources within the timeslot to different TRPs of the same network device.

[0068] For example, Figure 5 As shown, the terminal device is configured with an intra-time slot frequency hopping scheme. Based on the intra-time slot frequency hopping scheme, the terminal device adopts an intra-time slot beam hopping scheme to transmit PUSCH, that is, the PUSCH transmission of the terminal device on the first frequency hopping resource is oriented towards TRP1, and the PUSCH transmission on the second frequency hopping resource is oriented towards TRP2.

[0069] By adopting the intra-slot beam hopping scheme, the terminal device can obtain beam diversity gain within the time slot. Moreover, because the intra-slot beam hopping scheme is based on the intra-slot frequency hopping scheme, the complexity of the terminal device implementing the intra-slot beam hopping scheme is also low. However, in the above-mentioned intra-slot beam hopping scheme, the terminal device sends PUSCH to different TRPs of the network device by coordinating different frequency hopping resources within the time slot, and does not repeatedly transmit PUSCH on multiple frequency hopping resources within the time slot. As a result, the transmission reliability of PUSCH is low, making it difficult to combat performance degradation in congestion and deep fading.

[0070] Based on this, an embodiment of the present application provides an uplink channel transmission method that can be used to improve the transmission reliability of the PUSCH.

[0071] Please refer to Figure 6, which shows a schematic diagram of a communication system provided by an embodiment of the present application. The communication system may include: a terminal device 10 and a network device.

[0072] There are usually multiple terminal devices 10, and one or more terminal devices 10 can be distributed in each cell managed by each network device. The terminal devices 10 can include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE), mobile stations (MS), etc. For the convenience of description, in the embodiments of the present application, the devices mentioned above are collectively referred to as terminal devices.

[0073] A network device is a device deployed in an access network to provide wireless communication functions for a terminal device 10. Network devices may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems using different wireless access technologies, the names of devices with network device functions may be different. For example, in a 5G NR system, they are called gNodeB or gNB. As communication technology evolves, the name "network device" may change. For the sake of convenience of description, in the embodiments of the present application, the above-mentioned devices that provide wireless communication functions for the terminal device 10 are collectively referred to as network devices. In one example, the network device and the terminal device 10 communicate with each other through a certain air interface technology, such as a Uu interface.

[0074] In one example, a network device may be deployed with multiple TRPs, for example, Figure 6 As shown, the network devices correspond to TRP1, TRP2...TRPn (TRP in Figure 6 The reference number is 20). The terminal device can use different transmission beams to send uplink channels (such as PUSCH) to different TRPs, and the network device can receive uplink channels (such as PUSCH) sent by the terminal device through multiple TRPs. For example, due to the different relative orientations of different TRPs and terminal devices, the terminal device needs to use transmission beams with different beam directions to send uplink channels (such as PUSCH) to the TRP in the corresponding direction.

[0075] The "5G NR system" in the embodiments of this disclosure may also be referred to as a 5G system or an NR system, but those skilled in the art will understand the meaning. The technical solutions described in the embodiments of this disclosure are applicable to the 5G NR system and to subsequent evolution systems of the 5G NR system.

[0076] Please refer to Figure 7 , which shows a flowchart of an uplink channel transmission method provided by an embodiment of the present application, which can be applied to Figure 6In the communication system shown in FIG.

[0077] In step 710, the network device sends transmission indication information to the terminal device. The transmission indication information is used to indicate a first repetitive transmission scheme for sending PUSCH. The first repetitive transmission scheme is a combination of an inter-time slot repetitive transmission scheme and an intra-time slot beam hopping scheme.

[0078] In the embodiment of the present application, the network device indicates the PUSCH transmission scheme to the terminal device. To improve the transmission reliability of the PUSCH, the terminal device can repeatedly send the PUSCH; to obtain beam diversity gain at the same time, the terminal device can use beam hopping to send the PUSCH.

[0079] Based on this, in an embodiment of the present application, the network device instructs the terminal device to send a first repetition transmission scheme of PUSCH by transmitting indication information. The first repetition transmission scheme is a combination of an inter-time slot repetition transmission scheme and an intra-time slot beam hopping scheme. Optionally, the inter-time slot repetition transmission scheme is the above-mentioned PUSCH repetition type A transmission mode. Therefore, in the case of repeated transmission of PUSCH, the network device needs to indicate the intra-time slot beam hopping scheme to the terminal device so that the terminal device is clear about the first repetition transmission scheme.

[0080] The embodiments of the present application do not limit the specific manner in which the network device indicates the first repetitive transmission scheme. In one example, the network device can directly indicate to the terminal device that the intra-time slot transmission scheme is the intra-time slot beam hopping scheme, so that the transmission indication information includes: the intra-time slot transmission scheme is the intra-time slot beam hopping scheme; optionally, the network device can simultaneously indicate the frequency hopping scheme to the terminal device, so that the transmission indication information also includes: the intra-time slot frequency hopping scheme and / or the inter-time slot frequency hopping scheme. In another example, the network device can activate the first repetitive transmission scheme by configuring the frequency hopping scheme, so that the transmission indication information includes: when the intra-time slot frequency hopping scheme and / or the inter-time slot frequency hopping scheme are configured at the same time, the PUSCH transmission scheme is activated as the first repetitive transmission scheme.

[0081] In one example, the first repetitive transmission scheme includes performing inter-slot repetitive transmission within n time slots, and performing intra-slot beam hopping within each of the n time slots, where n is an integer greater than or equal to 1. Optionally, the inter-slot repetitive transmission scheme is the aforementioned PUSCH repetition type A transmission mode, whereby the terminal device performing inter-slot repetitive transmission within n time slots includes the terminal device transmitting a PUSCH once within each of the n time slots. That is, the number of PUSCH transmission repetitions is n.

[0082] In order to make the terminal device clear about the number of transmission repetitions, the network device may configure or indicate n for the terminal device. In one example, the network device may configure the number of transmission repetitions n for the terminal device, so that the above method further includes: the network device sends RRC (Radio Resource Control) signaling to the terminal device, and the RRC signaling is used to configure n. In another example, the network device may indicate the number of transmission repetitions n to the terminal device more dynamically. Optionally, the network device may explicitly indicate n to the terminal device, so that the above method further includes: the network device sends MAC (Media Access Control) CE (Control Element) to the terminal device, and the MAC CE is used to indicate n. Optionally, the network device may implicitly indicate n to the terminal device, so that the above method further includes: the network device sends DCI (Downlink Control Information) to the terminal device, and the DCI is used to indicate n. For example, the TDRA (Time Domain Resource Allocation) field in the DCI implicitly indicates n.

[0083] For further description of the first repeated transmission scheme, please refer to the following embodiments, which will not be elaborated here.

[0084] Step 720: The terminal device sends PUSCH to multiple TRPs of the network device in collaboration according to the first repetitive transmission scheme.

[0085] Upon receiving the transmission indication information, the terminal device may collaboratively transmit the PUSCH to multiple transmission points (TRPs) of the network device according to the first repetition transmission scheme indicated by the transmission indication information. The terminal device transmits the PUSCH using transmit beams in different directions for different transmission points of the network device. It should be understood that the transmission points described in the embodiments of the present application may also be referred to as transmission reception points.

[0086] In summary, the technical solution provided by the embodiment of the present application provides an uplink channel transmission method based on multiple TRPs, by which the terminal device collaboratively sends PUSCH to multiple transmission points of the network device according to the first repetition transmission scheme when the network device instructs the terminal device to send the first repetition transmission scheme of PUSCH. Since the first repetition transmission scheme is a combination of the inter-time slot repetition transmission scheme and the intra-time slot beam hopping scheme, the terminal device can obtain beam diversity gain through the intra-time slot beam hopping scheme while also improving the transmission reliability of PUSCH through the inter-time slot repetition transmission scheme, which can effectively combat performance deterioration in congestion and deep fading conditions, and achieve more flexible adaptation to business requirements with different delays and performance.

[0087] The following describes the frequency resources occupied by the frequency hopping resources in the first repetitive transmission scheme and the beam mapping of the frequency hopping resources.

[0088] First, it should be noted that in the embodiment of the present application, the resource sizes occupied by the corresponding frequency hopping resources in each of the n time slots are the same, and the resource sizes occupied by different frequency hopping resources in the same time slot in the n time slots are the same or different. Taking the example that each of the n time slots includes the first frequency hopping resource and the second frequency hopping resource, the resource sizes occupied by the corresponding frequency hopping resources in each of the n time slots are the same, including: the resource sizes occupied by the first frequency hopping resource in each of the n time slots are all the first resource size; the resource sizes occupied by the second frequency hopping resource in each of the n time slots are all the second resource size. Similarly, taking the example that each of the n time slots includes the first frequency hopping resource and the second frequency hopping resource, the resource sizes occupied by different frequency hopping resources in the same time slot in the n time slots are the same or different, including: the resource sizes occupied by the first frequency hopping resource and the second frequency hopping resource in the same time slot in the n time slots are the same or different.

[0089] Optionally, since different frequency hopping resources within the same time slot occupy the same bandwidth, the resource size occupied by the frequency hopping resource can generally be determined by the number of symbols occupied by the frequency hopping resource in the time domain. Therefore, the resource size occupied by the corresponding frequency hopping resources in each of the n time slots is the same, which can also be referred to as the number of symbols occupied by the corresponding frequency hopping resources in each of the n time slots in the time domain being the same. The resource sizes occupied by different frequency hopping resources within the same time slot in the n time slots are the same or different, which can also be referred to as the number of symbols occupied by different frequency hopping resources within the same time slot in the n time slots in the time domain being the same or different. Optionally, different frequency hopping resources do not overlap in the time domain; different frequency hopping resources may overlap in the frequency domain.

[0090] In one possible implementation, the frequency resources occupied by the corresponding frequency hopping resources in each of the n time slots are the same, and the frequency resources occupied by different frequency hopping resources in the same time slot in the n time slots are the same or different, and the beam mapping of the corresponding frequency hopping resources in each of the n time slots is the same.

[0091] Taking the example that each of n time slots includes a first frequency hopping resource and a second frequency hopping resource, the frequency resources occupied by the corresponding frequency hopping resources in each of the n time slots are the same, including: the frequency resources occupied by the first frequency hopping resources in each of the n time slots are all first frequency resources; the frequency resources occupied by the second frequency hopping resources in each of the n time slots are all second frequency resources.

[0092] Similarly, taking the example that each of n time slots includes a first frequency hopping resource and a second frequency hopping resource, the frequency resources occupied by different frequency hopping resources in the same time slot in the n time slots are the same or different, including: the frequency resources occupied by the first frequency hopping resource and the second frequency hopping resource in the same time slot in the n time slots are the same or different.

[0093] Similarly, each of the n time slots includes a first frequency hopping resource and a second frequency hopping resource; the beam mapping of the corresponding frequency hopping resources in each of the n time slots is the same, including: the first frequency hopping resource in each of the n time slots is mapped to the transmission beam corresponding to the first transmission point; and the second frequency hopping resource in each of the n time slots is mapped to the transmission beam corresponding to the second transmission point.

[0094] Optionally, since the bandwidth occupied by different frequency hopping resources in the same time slot is the same, the same or different frequency resources can usually be determined by the frequency starting position. If the frequency starting positions of different frequency hopping resources are the same, the frequency resources occupied by different frequency hopping resources are the same; if the frequency starting positions of different frequency hopping resources are different, the frequency resources occupied by different frequency hopping resources are different.

[0095] For example, Figure 8 As shown, n is 2, and the terminal device repeats transmitting PUSCH for the first time in time slot 1 and repeats transmitting PUSCH for the second time in time slot 2. Figure 8 As shown, both time slot 1 and time slot 2 include a first frequency hopping resource and a second frequency hopping resource. The frequency resources occupied by the first frequency hopping resource of time slot 1 and the first frequency hopping resource of time slot 2 are the same, and the frequency resources occupied by the second frequency hopping resource of time slot 1 and the second frequency hopping resource of time slot 2 are also the same; however, the frequency resources occupied by the first frequency hopping resource and the second frequency hopping resource of time slot 1 are different, and the frequency resources occupied by the first frequency hopping resource and the second frequency hopping resource of time slot 2 are also different. Figure 8 As shown, the spatial relationship information of the first frequency hopping resource of time slot 1 and the first frequency hopping resource of time slot 2 is the same, such as both are mapped to the transmission beam corresponding to TRP1; the spatial relationship information of the second frequency hopping resource of time slot 1 and the second frequency hopping resource of time slot 2 is also the same, such as both are mapped to the transmission beam corresponding to TRP2.

[0096] The beam mapping of the frequency hopping resources corresponding to each of the n time slots is the same, and intra-slot beam hopping is performed in each time slot, so that the terminal device needs to switch the transmission beam between two adjacent time slots. In one example, in order to reduce the number of beam switching, the network device can configure that only beam mapping flipping occurs in one or some time slots, that is, the above method also includes: the network device sends beam flip mapping information to the terminal device, and the beam flip mapping information is used to indicate that only beam mapping flipping occurs in k time slots out of the n time slots, and k is a positive integer less than or equal to n. Optionally, the network device can indicate the beam mapping flip by multiplexing beam mapping signaling, and the beam mapping signaling is used to indicate the mapping relationship between the beam transmission direction of the PUSCH and different transmission opportunities.

[0097] Taking the example of n time slots each including a first frequency hopping resource and a second frequency hopping resource, only beam mapping flipping occurs in k time slots among the n time slots, including: the first frequency hopping resource in each time slot among (nk) time slots is mapped to the transmission beam corresponding to the first transmission point; the second frequency hopping resource in each time slot among (nk) time slots is mapped to the transmission beam corresponding to the second transmission point; the first frequency hopping resource in each time slot among k time slots is mapped to the transmission beam corresponding to the second transmission point; and the second frequency hopping resource in each time slot among k time slots is mapped to the transmission beam corresponding to the first transmission point.

[0098] For example, Figure 9 As shown, n is 2, and the terminal device repeats transmitting PUSCH for the first time in time slot 1 and repeats transmitting PUSCH for the second time in time slot 2. Figure 9 As shown in FIG, the spatial relationship information of the first frequency hopping resource and the second frequency hopping resource of time slot 1 is different. For example, the first frequency hopping resource of time slot 1 is mapped to the transmit beam corresponding to TRP1, and the second frequency hopping resource of time slot 1 is mapped to the transmit beam corresponding to TRP2. In order to reduce the number of beam switching, the network device configures the terminal device to perform beam mapping flipping in time slot 2, so that Figure 9 As shown, the spatial relationship information of the first frequency hopping resource of time slot 2 and the second frequency hopping resource of time slot 1 is the same, such as mapped to the transmission beam corresponding to TRP2; the spatial relationship information of the second frequency hopping resource of time slot 2 and the first frequency hopping resource of time slot 1 is the same, such as mapped to the transmission beam corresponding to TRP1.

[0099] In one example, in order to further obtain frequency diversity gain on the same beam, the network device can configure a certain time slot or certain time slots to only undergo frequency mapping flipping, that is, the above method further includes: the network device sends frequency flip mapping information to the terminal device, the frequency flip mapping information is used to indicate that only frequency mapping flipping occurs in i time slots out of n time slots, where i is a positive integer less than or equal to n. Optionally, the network device can indicate frequency mapping flipping by multiplexing beam mapping signaling, where the beam mapping signaling is used to indicate the mapping relationship between the beam transmission direction of the PUSCH and different transmission opportunities.

[0100] Each of the n time slots includes a first frequency hopping resource and a second frequency hopping resource; only frequency mapping flipping occurs in i time slots among the n time slots, including: the frequency resources occupied by the first frequency hopping resources in each of the (ni) time slots are all first frequency resources; the frequency resources occupied by the second frequency hopping resources in each of the (ni) time slots are all second frequency resources; the frequency resources occupied by the first frequency hopping resources in each of the i time slots are all second frequency resources; and the frequency resources occupied by the second frequency hopping resources in each of the i time slots are all first frequency resources.

[0101] For example, Figure 10 As shown, n is 2, and the terminal device repeats transmitting PUSCH for the first time in time slot 1 and repeats transmitting PUSCH for the second time in time slot 2. Figure 10 As shown, the spatial relationship information of the first frequency hopping resource of time slot 1 and the first frequency hopping resource of time slot 2 is the same, such as both are mapped to the transmission beam corresponding to TRP1; the spatial relationship information of the second frequency hopping resource of time slot 1 and the second frequency hopping resource of time slot 2 is also the same, such as both are mapped to the transmission beam corresponding to TRP2. Figure 10 As shown, the frequency resources occupied by the first frequency hopping resource and the second frequency hopping resource of time slot 1 are different. For example, the frequency resource occupied by the first frequency hopping resource of time slot 1 is the first frequency resource, and the frequency resource occupied by the second frequency hopping resource of time slot 1 is the second frequency resource. In order to obtain frequency diversity gain on the same beam, the network device configures the terminal device to perform frequency mapping flipping in time slot 2, so that Figure 10 As shown, the frequency resources occupied by the first frequency hopping resource of time slot 2 and the second frequency hopping resource of time slot 1 are the same, such as the occupied frequency resources are both second frequency resources; the frequency resources occupied by the second frequency hopping resource of time slot 2 and the first frequency hopping resource of time slot 1 are the same, such as the occupied frequency resources are both first frequency resources.

[0102] In another possible implementation, the frequency resources occupied by corresponding frequency hopping resources in adjacent time slots in n time slots are different, and the frequency resources occupied by different frequency hopping resources in the same time slot in n time slots are the same or different, and the beam mapping of the corresponding frequency hopping resources in each time slot in n time slots is the same.

[0103] Taking the example of n time slots each including a first frequency hopping resource and a second frequency hopping resource, the frequency resources occupied by the corresponding frequency hopping resources in adjacent time slots in the n time slots are different, including: the frequency resources occupied by the first frequency hopping resources in adjacent time slots in the n time slots are different; the frequency resources occupied by the second frequency hopping resources in adjacent time slots in the n time slots are also different.

[0104] Similarly, taking the example that each of n time slots includes a first frequency hopping resource and a second frequency hopping resource, the frequency resources occupied by different frequency hopping resources in the same time slot in the n time slots are the same or different, including: the frequency resources occupied by the first frequency hopping resource and the second frequency hopping resource in the same time slot in the n time slots are the same or different.

[0105] Taking the example of each of n time slots including a first frequency hopping resource and a second frequency hopping resource, the beam mapping of the corresponding frequency hopping resources in each of the n time slots is the same, including: the first frequency hopping resource in each of the n time slots is mapped to the transmission beam corresponding to the first transmission point; and the second frequency hopping resource in each of the n time slots is mapped to the transmission beam corresponding to the second transmission point.

[0106] Optionally, since the bandwidth occupied by different frequency hopping resources in the same time slot is the same, the same or different frequency resources can usually be determined by the frequency starting position. If the frequency starting positions of different frequency hopping resources are the same, the frequency resources occupied by different frequency hopping resources are the same; if the frequency starting positions of different frequency hopping resources are different, the frequency resources occupied by different frequency hopping resources are different.

[0107] For example, Figure 11 As shown, n is 2, and the terminal device repeats transmitting PUSCH for the first time in time slot 1 and repeats transmitting PUSCH for the second time in time slot 2. Figure 11 As shown, both time slot 1 and time slot 2 include a first frequency hopping resource and a second frequency hopping resource. The frequency resources occupied by the first frequency hopping resource and the second frequency hopping resource of time slot 1 are the same, and the frequency resources occupied by the first frequency hopping resource and the second frequency hopping resource of time slot 2 are also the same; however, the frequency resources occupied by the first frequency hopping resource of time slot 1 and the first frequency hopping resource of time slot 2 are different, and the frequency resources occupied by the second frequency hopping resource of time slot 1 and the second frequency hopping resource of time slot 2 are also different. Figure 11As shown, the spatial relationship information of the first frequency hopping resource of time slot 1 and the first frequency hopping resource of time slot 2 is the same, such as both are mapped to the transmission beam corresponding to TRP1; the spatial relationship information of the second frequency hopping resource of time slot 1 and the second frequency hopping resource of time slot 2 is also the same, such as both are mapped to the transmission beam corresponding to TRP2.

[0108] In one example, to reduce the number of beam switching times, the network device may configure beam mapping flipping to occur only within one or certain time slots, so that the above method further includes: the network device sends beam flip mapping information to the terminal device, where the beam flip mapping information is used to indicate that beam mapping flipping only occurs within k time slots out of n time slots, where k is a positive integer less than or equal to n. Optionally, the network device may indicate beam mapping flipping by multiplexing beam mapping signaling, where the beam mapping signaling is used to indicate a mapping relationship between a PUSCH beam transmission direction and different transmission opportunities.

[0109] Taking the example of n time slots each including a first frequency hopping resource and a second frequency hopping resource, only beam mapping flipping occurs in k time slots among the n time slots, including: the first frequency hopping resource in each time slot among (nk) time slots is mapped to the transmission beam corresponding to the first transmission point; the second frequency hopping resource in each time slot among (nk) time slots is mapped to the transmission beam corresponding to the second transmission point; the first frequency hopping resource in each time slot among k time slots is mapped to the transmission beam corresponding to the second transmission point; and the second frequency hopping resource in each time slot among k time slots is mapped to the transmission beam corresponding to the first transmission point.

[0110] For example, Figure 12 As shown, n is 2, and the terminal device repeats transmitting PUSCH for the first time in time slot 1 and repeats transmitting PUSCH for the second time in time slot 2. Figure 12 As shown in FIG, the spatial relationship information of the first frequency hopping resource and the second frequency hopping resource of time slot 1 is different. For example, the first frequency hopping resource of time slot 1 is mapped to the transmit beam corresponding to TRP1, and the second frequency hopping resource of time slot 1 is mapped to the transmit beam corresponding to TRP2. In order to reduce the number of beam switching, the network device configures the terminal device to perform beam mapping flipping in time slot 2, so that Figure 12 As shown, the spatial relationship information of the first frequency hopping resource of time slot 2 and the second frequency hopping resource of time slot 1 is the same, such as mapped to the transmission beam corresponding to TRP2; the spatial relationship information of the second frequency hopping resource of time slot 2 and the first frequency hopping resource of time slot 1 is the same, such as mapped to the transmission beam corresponding to TRP1.

[0111] In summary, the technical solution provided by the embodiments of the present application reduces the complexity of implementing the intra-time slot beam hopping solution for terminal devices by implementing the intra-time slot beam hopping solution based on the frequency hopping solution, and enables flexible combination of intra-time slot beam hopping and intra-time slot frequency hopping / inter-time slot frequency hopping. Furthermore, in the embodiments of the present application, the network device can configure frequency mapping flipping for the terminal device so that the same beam can obtain frequency diversity gain; the network device can also configure beam mapping flipping for the terminal device, thereby reducing the number of beam switching times.
