Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to an uplink service channel rate matching method, apparatus, storage medium and electronic device. Background Technology

[0002] 5G New Radio (5G NR) is the next generation of mobile communication technology following Long Term Evolution (LTE), which can provide various users and applications with access to information and data sharing anytime, anywhere.

[0003] To facilitate access to 40M NR base station equipment for both 40M NR and 20M NR terminals, a PUSCH rate matching scheme has been proposed for downlink service channels. However, a corresponding PUSCH rate matching scheme is lacking for uplink service channels, resulting in a significant decrease in the uplink rate of 40M NR terminals. This affects the performance and capacity of DSS (Dynamic Spectrum Sharing) and leads to a poor user experience.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0042] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided to make this disclosure more comprehensive and complete, and to fully convey the concept of the example embodiments to those skilled in the art. The described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a full understanding of embodiments of this disclosure. However, those skilled in the art will recognize that the technical solutions of this disclosure can be practiced with one or more of the specific details omitted, or other methods, components, apparatus, steps, etc., can be employed. In other instances, well-known technical solutions are not shown or described in detail to avoid obscuring various aspects of this disclosure.

[0043] Furthermore, the accompanying drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted. Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0044] In NR (New Radio), the 40MHz band typically contains NR PUCCH (Physical Uplink Control Channel) and / or LTE PUCCH channels; the PUCCH carries uplink control information. The presence of the PUCCH channel leads to discontinuity in NR PUSCH (Physical Uplink Shared Channel) PRB (Physical Resource Block) resources, resulting in a decrease in the uplink rate of 40MHz NR terminals.

[0045] Based on this, an exemplary embodiment of this disclosure provides an uplink service channel rate matching method, comprising two parts: one for the base station equipment side and the other for the terminal equipment side. (Refer to...) Figure 1 For use on the base station equipment side, the uplink channel rate matching method may include:

[0046] Step S110: Send resource occupancy information to the terminal device. The resource occupancy information includes the time and frequency resources occupied by the Physical Uplink Control Channel (PUCCH).

[0047] Step S130: When receiving the Physical Uplink Shared Channel (PUSCH) sent by the terminal device, perform PUSCH rate matching on the PUCCH in the middle frequency band of the splicing band, and transmit all time-frequency resources in the splicing band that are not occupied by PUCCH as NRPUSCH information.

[0048] In the exemplary embodiments of this disclosure, when transmitting uplink services, resource occupancy information needs to be pre-configured on the base station equipment side. This resource occupancy information includes the time-frequency resources occupied by the PUCCH. For the NR band, the NR PUCCH occupies the time-frequency resources of the highest and lowest frequency bands of the NR band; for the LTE band, the LTE PUCCH occupies the time-frequency resources of the highest and lowest frequency bands of the LTE band. Therefore, the time-frequency resources occupied by the PUCCH include the highest and lowest frequency bands in the band.

[0049] For a single NR band, the time-frequency resources between the highest and lowest frequency bands are typically used as NR PUSCH channels to transmit data. However, the time-frequency resources available for use as NR PUSCH channels are limited for a single NR band, thus restricting the transmission rate.

[0050] Based on this, in the exemplary embodiments of this disclosure, time-frequency resources in the spliced ​​frequency band are mainly used as NRPUSCH for data uploading. The spliced ​​frequency band can be formed by splicing adjacent pure NR frequency bands, or it can be formed by splicing NR and LTE frequency bands.

[0051] The splicing frequency band and its resource configuration will be explained below through different implementation methods:

[0052] In implementation method one, the spliced ​​frequency band consists of at least two adjacent new radio frequency bands (NR bands), and the frequencies of the two adjacent new NR bands can be continuous. (Refer to...) Figure 2 The diagram shows a structural schematic of a spliced ​​frequency band composed of two NR frequency bands; Figure 2 In this context, if two adjacent NR bands are 20MHz bands, then the band formed by splicing these two bands is a 40MHz NR band.

[0053] Because the highest and lowest frequency bands of each 20MHz NR band are occupied by NR PUCCH, the middle frequency band of the 40MHz NR band, formed by the two 20MHz NR bands, is also occupied by NR PUCCH. This divides the 40MHz NR band into two parts. Even if time-frequency resources other than NR PUCCH are used as NR PUSCH, the continuity of NR PUSCH scheduling within the 40MHz NR band cannot be guaranteed. The middle frequency band here refers to the band between the highest and lowest frequency bands. The specific width and location of the middle frequency band can be determined based on actual conditions and are not specifically limited here.

[0054] The exemplary embodiments of this disclosure perform PUSCH rate matching on the PUCCH in the middle frequency band of the splicing band. When loading useful information into the PUSCH, the base station equipment can avoid the time-frequency resources occupied by the PUCCH in the splicing band and not load useful information into the time-frequency resources where the PUSCH is unavailable. That is, the useful information of the PUSCH is not loaded into the time-frequency resources occupied by the PUCCH.

[0055] In other words, by performing PUSCH rate matching on the PUCCH in the middle band of the splicing band, useful PUSCH information can be loaded into time-frequency resources other than the PUCCH, i.e., loaded into any time-frequency resource in the splicing band except for the PUCCH. This ensures the continuous availability of time-frequency resources within the splicing band. Even if there is a PUCCH in the middle of the splicing band, it does not affect the use of the frequency bands on both sides of the PUCCH as time-frequency resources for PUSCH. The time-frequency resources in the frequency bands on both sides can be used to load useful PUSCH information, thereby improving the utilization rate of time-frequency resources, enhancing the performance and capacity of NR or DSS networks, increasing the uplink data transmission rate, and ultimately improving the user experience.

[0056] In practical applications, besides adopting Figure 2 Besides the two NR bands shown, which can be spliced ​​together to form a spliced ​​band, three, four, or even more NR bands can also be spliced ​​together. Furthermore, the NR bands used for splicing can be the aforementioned 20MHz NR band (representing a 20MHz bandwidth NR band), or 10MHz NR bands, 30MHz NR bands, 40MHz NR bands, 100MHz NR bands, etc., and these bands can be combined arbitrarily.

[0057] For spliced ​​frequency bands composed of NR frequency bands, different PUSCH rate matching methods can be used depending on the format of the PUSCH in the middle frequency band of the spliced ​​frequency band. For example, Figure 2As shown, when the NR PUCCH format of the intermediate frequency band is NR long PUCCH, resource block (RB) level PUSCH rate matching can be performed on the NR long PUCCH of the spliced ​​frequency band. That is, for NR long PUCCH, resource block (RB) level PUSCH rate matching can be used. Here, 1 RB = 7 symbols × 12 subcarriers = 84 REs (Resource Elements), and 1 RE = 1 symbol × 1 subcarrier.

[0058] For RB-level PUSCH rate matching, a bitmap is used to indicate which specific RB resource blocks cannot be used for PUSCH data transmission. Figure 2 Taking the spliced ​​band formed by two 20MHz NR bands as an example, suppose the lowest frequency band of the upper 20MHz NR band and the highest frequency band of the lower 20MHz NR band overlap and are both occupied by long PUCCHs. If the long PUCCH occupies 3 RBs in both the lowest and highest frequency bands, then the PUCCH in the middle frequency band of the spliced ​​band needs to be avoided at the 6 RB level, and PUSCH information should not be loaded. In practical applications, the number of RB-level avoidances can be determined according to the number of RBs occupied by the long PUCCH, and this exemplary embodiment does not impose any special limitations on this.

[0059] In practical applications, the format of a PUCCH can be determined based on the number of OFDM (Orthogonal Frequency Division Multiplexing) symbols it occupies. When a PUCCH occupies a large number of OFDM symbols, such as four or more, it can be classified as a long PUCCH. Conversely, when a PUCCH occupies a small number of OFDM symbols, such as one or two, it can be classified as a short PUCCH.

[0060] Reference Figure 3 The NR PUCCH in the middle frequency band of the spliced ​​frequency band is the NR short PUCCH. For the short PUCCH, the exemplary embodiment of this disclosure uses RE-level PUSCH rate matching. RE-level PUSCH rate matching uses a bitmap to indicate which specific RE resource units cannot be used for PUSCH information transmission. For example, Figure 3 One of the short PUCCHs occupies 3 RBs in height but only 2 symbols in width. Therefore, for two short PUCCHs that are in contact in two NR bands, 12 RE-level avoidances are required, and no PUSCH information is loaded.

[0061] In practical applications, the number of RE-level avoidance operations can be determined based on the number of REs occupied by the short PUCCH, and the exemplary embodiments disclosed herein do not impose any special limitations on this.

[0062] In the exemplary embodiments of this disclosure, for long PUCCH, the base station device can send the RB time-frequency resources occupied by the long PUCCH to the terminal device through IE (Information Element), for example, IE1-RateMatching Pattern NR-Long PUCCH; for short PUCCH, the RB time-frequency resources occupied by the short PUCCH can be sent to the terminal device through IE2, for example, IE2-RateMatching Pattern NR-Long PUCCH.

[0063] In implementation method two, the spliced ​​frequency band can also be formed by splicing together the NR frequency band and the LTE frequency band. (Refer to...) Figure 4 The diagram shows a spliced ​​band structure for a DSS (Dynamic Spectrum Sharing) hybrid band, which is composed of NR bands and LTE bands in a 1:1 ratio. Figure 4 In this configuration, the bandwidth of the NR band is greater than that of the LTE band. Parts of the LTE and NR bands overlap, and these overlapping bands can be used as both LTE and NR channels, a phenomenon known as Dynamic Spectrum Sharing (DSS). Specifically, the highest and lowest frequency bands of the NR band are used for transmitting NR PUCCH, while the highest and lowest frequency bands of the LTE band are used for transmitting LTE PUCCH. For example... Figure 4 As shown, the 20MHz LTE band is located in the lower half of the 40MHz NR band. Therefore, the LTE PUCCH of the highest frequency band of the 20MHz LTE band is located in the middle frequency band of the spliced ​​band. At this time, it is necessary to perform RB-level PUSCH rate matching on the LTE PUCCH of the highest frequency band of the 20MHz LTE band.

[0064] If the LTE PUCCH in the lowest frequency band of the 20MHz LTE band is located in the middle frequency band of the spliced ​​band, then RB-level PUSCH rate matching is required for the LTE PUCCH in the lowest frequency band of the 20MHz LTE band. If both LTE PUCCHs are located in the middle frequency band of the spliced ​​band, then RB-level PUSCH rate matching is required for both LTE PUCCHs.

[0065] Under this spliced ​​frequency band, the RB time-frequency resources occupied by the LTE PUCCH can be sent to the terminal device by adding IE3, for example, IE3-Rate Matching Pattern LTE-PUCCH.

[0066] In practical applications, the ratio of NR bands to LTE bands used for band splicing can also be 2:1, with one NR band having the same bandwidth and location as the LTE band. The specific number of NR and LTE bands can be set according to actual needs and is not limited here. (See reference...) Figure 5 This diagram illustrates a structure where a spliced ​​frequency band is composed of NR and LTE frequency bands in a 2:1 ratio; as an example, Figure 5 The image shows a 40MHz DSS band formed by splicing a 20MHz NR band and a 20MHz LTE / NR band.

[0067] like Figure 5 As shown, in the bandwidth shared by the NR and LTE bands, the highest and lowest frequency bands include NRPUCCH and LTE PUCCH, respectively, with the LTE PUCCH located inside the NR PUCCH. The highest and lowest frequency bands of the other NR band are used to transmit NR PUCCH, resulting in three PUCCHs in the middle band of the spliced ​​band, namely two NR PUCCHs and one LTE PUCCH.

[0068] In this exemplary embodiment of the present disclosure, RB-level PUSCH rate matching needs to be performed on these three PUCCHs simultaneously, that is, RB-level avoidance is performed on these three PUCCHs, and PUSCH information is not loaded. If the above three PUCCHs each occupy 3 RBs, then 9 RB-level avoidance is required for the PUCCHs in the middle frequency band of the splicing band.

[0069] In practical applications, the number of combinations of NR and DSS bands and the specific bandwidth can be adjusted according to actual needs, and the exemplary embodiments disclosed herein do not impose any special limitations on this.

[0070] It should be noted that under this spliced ​​frequency band, the RB time-frequency resources occupied by LTE PUCCH and NR PUCCH can be sent to the terminal device by adding IE4, for example, IE4-Rate Matching Pattern LTE and NR-PUCCH.

[0071] Reference Figure 6 For use on the terminal device side, the uplink service channel PUSCH rate matching method provided in this disclosure embodiment may include:

[0072] Step S610: Obtain resource occupancy information, which includes the time and frequency resources occupied by the Physical Uplink Control Channel (PUCCH).

[0073] Step S630: Based on the resource occupancy information, all time-frequency resources within the splicing band that are not occupied by PUCCH are transmitted as PUSCH information.

[0074] According to the aforementioned uplink service channel rate matching method for the base station equipment side, the RB time-frequency resources occupied by the PUCCH are stored in the IE. Therefore, during the process of obtaining resource occupancy information, in the idle state, i.e., when the terminal equipment is not connected to the base station equipment, the resource occupancy information can be obtained from the SIB1 message, i.e., IE1, IE2, IE3, or IE4 can be obtained. Here, SIB1 is a type of SIB (System Information Block). SIB is mainly used to broadcast cell messages, providing the terminal equipment with several parameters required for cell camping, retransmission, link establishment, etc.

[0075] In the connected state, that is, when the terminal device is connected to the base station device, the resource occupancy information is obtained from the RRC (Radio Resource Control) message, that is, IE1, IE2, IE3 or IE4.

[0076] After obtaining the time-frequency resource information occupied by PUCCH, we can avoid that PUCCH time-frequency resource, i.e., the time-frequency resource where PUSCH is unavailable. Useful information can be loaded into the available PUSCH time-frequency resources, while useless information can be loaded into the unavailable PUSCH time-frequency resources. This loading method is used to load and upload PUSCH information. The loading types can be referenced above. Figures 2-5 The method shown will not be elaborated further here.

[0077] Reference Figure 7 This illustrates a signaling flowchart for uplink service channel transmission. Figure 7In this process, the terminal device obtains resource occupancy information from the SIB1 or RRC messages sent by the base station. Based on this information, it determines the time-frequency resources occupied by the PUCCH, and loads PUSCH information onto the intermediate frequency band of the splicing band after avoiding the PUCCH time-frequency resources. When sending NR PUSCH to the base station, it can avoid the time-frequency resources occupied by the PUCCH. Simultaneously, when receiving NR PUSCH, the base station can perform PUSCH rate matching on the PUCCH in the intermediate frequency band of the splicing band, allowing it to receive NR PUSCH across PUCCHs, avoiding their impact, ensuring the continuity of uplink PUSCH scheduling within the splicing band, thereby improving the uplink speed of the NR terminal device and enhancing the user experience.

[0078] Reference Figure 8 This paper illustrates a workflow diagram for uplink service channel transmission composed of spliced ​​frequency bands from pure NR frequency bands. In this case, uplink service channel transmission is mainly performed by NR base stations and terminal equipment. Figure 8 In the process, after the NR base station is powered on and initialized, the process first proceeds to step S801 to determine whether at least two pure NR frequency bands are configured. If so, the spliced ​​frequency band is formed by splicing pure NR frequency bands. Then, the process proceeds to step S802 to determine whether the PUSCH rate matching switch is turned on. If the switch is turned on, the process proceeds to step S803 to determine whether the middle frequency band of the spliced ​​frequency band is a long PUCCH. If so, i.e., the middle frequency band is a long PUCCH, the process proceeds to step S804 to notify the terminal device of the RB position of the long PUCCH in the middle frequency band by adding IE1 to the idle state SIB1 message or the connected state RRC message. Then, the process proceeds to step S805, where the terminal device avoids the RB position of the long PUCCH when sending uplink PUSCH. Finally, the process proceeds to step S806, where the base station device performs RB-level rate matching on the long PUCCH when receiving uplink PUSCH to avoid receiving useful PUSCH information from the long PUCCH.

[0079] If the middle frequency band of the spliced ​​frequency band is not a long PUCCH, but a short PUCCH, then proceed to step S807, and notify the terminal device of the RE position of the short PUCCH in the middle frequency band by adding IE2 to the idle state SIB1 message or the connected state RRC message; then proceed to step S808, when the terminal device sends uplink PUSCH, it avoids the RE position of the short PUCCH; then proceed to step S809, when the base station device receives uplink PUSCH, it performs RE-level rate matching on the short PUCCH to avoid receiving useful PUSCH information from the short PUCCH.

[0080] Reference Figure 9This paper illustrates a workflow diagram for uplink service channel transmission composed of spliced ​​frequency bands consisting of NR band, LTE band, and DSS band. In this case, uplink service channel transmission is mainly performed by DSS base station and terminal equipment. Figure 9 In the process, after the DSS base station is powered on and initialized, the system first proceeds to step S901 to determine whether the PUSCH rate matching switch is on. If the switch is on, the system proceeds to step S902 to determine whether the NR and LTE frequency bands are configured. If so, the system proceeds to step S903 to determine the ratio of the NR and LTE frequency bands. If the ratio is 1:1, the system proceeds to step S904 to notify the terminal device of the RB position of the intermediate frequency band PUCCH by adding IE3 to the idle state SIB1 message or the connected state RRC message. Then, the system proceeds to step S905, where the terminal device avoids the RB position of the intermediate frequency band PUCCH when sending uplink PUSCH. Finally, in step S906, the base station performs RB-level rate matching on the intermediate frequency band PUCCH when receiving uplink PUSCH.

[0081] In step S903, if the determined ratio of NR band to LTE band is 2:1, proceed to step S907, and notify the terminal device of the RB position of the intermediate frequency band PUCCH by adding IE4 to the idle state SIB1 message or the connected state RRC message; then proceed to step S905, when the terminal device sends the uplink PUSCH, it avoids the RB position of the intermediate frequency band PUCCH; in step S906, when the base station device receives the uplink PUSCH, it performs RB-level rate matching on the intermediate frequency band PUCCH.

[0082] The uplink service channel rate matching method provided in the exemplary embodiments of this disclosure, on the one hand, ensures that the terminal device avoids the PUCCH when uploading PUSCH by sending resource occupancy information to the terminal device, and loads useful information into the available time-frequency resources of the PUSCH. On the other hand, when the base station device receives the PUSCH, it can avoid the time-frequency resources occupied by the PUCCH by performing PUSCH rate matching on the PUCCH in the middle frequency band of the splicing band, and schedule the PUSCH on other time-frequency resources in the splicing band. This can expand the range of available time-frequency resources for PUSCH, ensure the continuity of PUSCH scheduling in the splicing band, improve the utilization rate of time-frequency resources, and thus improve the uplink rate of the terminal device and enhance the user experience.

[0083] It should be noted that although the steps of the method in this invention are described in a specific order in the accompanying drawings, this does not require or imply that the steps must be performed in that specific order, or that all the steps shown must be performed to achieve the desired result. Additional or alternative steps may be omitted, multiple steps may be combined into one step, and / or one step may be broken down into multiple steps.
