Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of communication, and in particular to a power sharing method and a wireless access device. BACKGROUND
[0002] The services of long term evolution (LTE) and new radio (NR) have the characteristic of strong burstiness, which causes the instantaneous full power or instantaneous idle power on the radio frequency module of the base station.
[0003] Currently, the LTE function module and the NR function module are simultaneously present on one base station, and the two function modules share the power amplifier on one radio frequency module channel. Since the services of LTE and NR have the characteristic of strong burstiness, the use of the power amplifier by the LTE function module and the NR function module is unbalanced at the same time, and then the function module of the instantaneous idle function can share the surplus power with the function module of the instantaneous full function, thereby improving the use efficiency of the power. For example, the LTE function module shares the power with the NR function module, or the NR function module shares the power with the LTE function module.
[0004] However, when the LTE function module shares the power with the NR function module, in order to ensure the basic signal measurement and user access of the cell using LTE, the power of the reference signal (RS) must be reserved and cannot be shared, such as the cell-specific reference signal (CRS). Then, in the multiple symbols of one time slot of LTE, some symbols have REs that need to carry RS, and then the power shared with the NR function module needs to subtract the power of the RE of the RS; in other symbols, there is no RE that needs to carry RS, and then the NR function module can share all the power.
[0005] Since the power shared by the symbols with REs that need to carry RS and the symbols with REs that do not need to carry RS is not equal, but the number of REs used by the NR function module is the same, the power density between these symbols is not equal. According to the link simulation demodulation, if the power density between the symbols is different by 2dB, then when the modulation and coding scheme (MCS) > 16, the cyclic redundancy check (CRC) will be demodulated incorrectly, which causes only a lower MCS to be used, resulting in lower transmission efficiency. SUMMARY

[0053] It should be noted that, Figure 1-1 The communication system 100 can also include other network devices, such as wireless relay devices and wireless backhaul devices, which are not shown in the figure. Figure 1-1
[0054] Moreover, various aspects or features of the disclosure can be implemented as a method, apparatus, or article of manufacture using standard programming and / or engineering techniques. The term "article of manufacture" as used herein is intended to encompass a computer program accessible from any computer-readable device, carrier, or media. For example, computer-readable media can include but are not limited to magnetic storage devices (e.g., hard disk, floppy disk, magnetic strips, etc.), optical disks (e.g., compact disk (CD), digital versatile disk (DVD), etc.), smart cards, and flash memory devices (e.g., EPROM, card, stick, or key drive, etc.). Additionally, various storage media described herein can represent one or more devices and / or other machine-readable media for storing information. The term "machine- readable medium" can include, without being limited to, wireless channels and various other media capable of storing, containing, and / or carrying instruction(s) and / or data.
[0055] Due to the bursty nature of LTE traffic and NR traffic, the usage of power amplifier by LTE function module and NR function module is not balanced in the same time. The function module of transient idle function can share the surplus power to the function module of transient full function, to improve the usage efficiency of power. For example, LTE function module shares power to NR function module, or NR function module shares power to LTE function module.
[0056] However, when LTE function module shares power to NR function module, in order to guarantee the basic signal measurement of using LTE cell and user access, the reference signal (RS) power must be reserved and cannot be shared out. Then, in the multiple symbols of one time slot of LTE, some symbols have REs that need to carry RS, so the power shared to NR function module needs to subtract the power of RE of RS; in other symbols, there is no RE that needs to carry RS, so the whole power can be shared to NR function module.
[0057] For example, as shown in FIG. 3, in the LTE time slot, the first symbol has REs that need to carry RS, so the power shared to NR function module needs to subtract the power of RE of RS; the second symbol has no RE that needs to carry RS, so the whole power can be shared to NR function module. Figure 1-2As shown, the symbols with REs that need to carry RS are symbols 0 / 4 / 7 / 11, and the symbols without REs that need to carry RS are symbols 1 / 2 / 3 / 5 / 6 / 8 / 9 / 10 / 12 / 13. According to a typical configuration in the current network, the power of the REs carrying RS is 3dB higher than the power of the REs carrying PDSCH in the same symbol (i.e. the power of RS is twice the power of RE). Then in the symbols carrying RS, for example, symbol 4, the total power is 600, and the total power required by 2 RS is 200, so the total power of the remaining REs is 400, i.e. the power that can be shared is 400. In the symbols without REs that need to carry RS, for example, symbol 10, the total power is 600, and the total power of RS is 0, so the total power of REs is 600, i.e. the power that can be shared is 600.
[0058] Then, the power spectral density on symbol 4 of the NR power module is 400 / 12, and the power spectral density on symbol 10 is 600 / 12, i.e. the difference between the two is 10*log 10 (600 / 400) = 1.76dB. According to the simulation demodulation of the link, if the difference between the symbols is 2dB, the CRC will be incorrect when the MCS > 16, which results in the use of a lower MCS, leading to lower transmission efficiency. Currently, if the power densities of the symbols are different, the smaller power is used. For example, the power on symbol 10 is only 400, which makes the power densities of symbol 10 and symbol 4 equal, resulting in that the power is not fully utilized in the sharing process.
[0059] Therefore, the present application provides a power sharing method and a wireless access device, which are used for a wireless access device including an NR function module and an LTE function module sharing a radio frequency channel, and perform power sharing for the NR function module and the LTE function module.
[0060] The present application is used for a wireless access device, and the wireless access device includes an NR function module and an LTE function module, and the NR function module and the LTE function module share a radio frequency channel. The NR function module first acquires a cell reference signal pattern of an LTE carrier, and then determines a puncturing pattern of an NR carrier according to the cell reference signal pattern of the LTE carrier, i.e. the power of some REs of a symbol in the NR carrier is 0, so that when the NR function module acquires shared power of the LTE carrier and performs power allocation for the NR carrier according to the puncturing pattern of the NR carrier and the shared power, the power densities of the symbols of the NR carrier are equal.
[0061] For example, as shown in Figure 2-1 An embodiment one of the power sharing method provided by the present application includes the following steps:
[0062] 201. The LTE function module adds the LTE carrier into a power sharing group.
[0063] In this embodiment, the LTE function module can add LTE carriers that need to be shared to the power sharing group. It should be noted that an LTE carrier can include multiple time slots, a time slot can include multiple symbols, and each symbol can include multiple REs. For example, an LTE carrier may have one time slot, one time slot may include two resource blocks (RBs), one RB may include seven symbols, and each symbol may include twelve REs.
[0064] 202. The NR function module adds the NR carrier to the power sharing group.
[0065] In this embodiment, the NR function module can add an NR carrier to a power sharing group. It should be noted that an NR carrier can also include multiple time slots, and each time slot can include multiple symbols, with each symbol including multiple REs. For example, an LTE carrier has one time slot, one time slot includes two resource blocks (RBs), one RB includes seven symbols, and each symbol includes 12 REs.
[0066] When LTE and NR carriers are added to the same power-sharing group simultaneously, they share the power on the radio frequency module channel. For example, if symbol A of the LTE carrier and symbol B of the NR carrier overlap in the time domain, the total power of symbol A and symbol B is a constant, such as 600 (mW).
[0067] For example, such as Figure 2-2 The diagram illustrates a time slot in an LTE carrier and a time slot in an NR carrier. Symbol 4 of the LTE carrier has two RSs, each with a power of 100, for a total power of 200. If the maximum power of the RF channel is 600, then symbol 4 of the LTE carrier has 600 - 200 = 400 power remaining, which can be shared with the NR carrier. Similarly, symbol 10 of the LTE carrier has zero RSs, meaning symbol 6 of the LTE carrier has 600 power remaining, which can be shared with the NR carrier.
[0068] 203. The LTE function module sends the cell reference signal pattern of the LTE carrier to the NR function module.
[0069] In this embodiment of the application, in order for the NR function module to calculate the punch pattern of the NR carrier, the LTE function module can send the cell reference signal pattern of the LTE carrier to the NR function module.
[0070] For example, such as Figure 2-3As shown, it is a cell reference signal pattern of an LTE carrier based on 4 antenna ports (port 0 / 1 / 2 / 3 respectively). In the cell reference signal pattern of the LTE carrier, it can include which symbols in the LTE carrier in each antenna port carry RS, and the number of RS carried on each symbol. For example, in port 0, 2 RS are carried on symbols 0 / 4 / 7 / 11 respectively. In some possible implementation, the cell reference signal pattern of the LTE carrier can also include the power of a single RS, for example, the power of the RS is 100. In some possible implementation, the cell reference signal pattern of the LTE carrier can also include REs with 0 power. For example, in port 0, REs with 0 power are in symbols 0 / 1 / 4 / 7 / 8 / 11 respectively. These REs are used to send RS on other antenna ports. In some possible implementation, the message of the cell reference signal pattern of the LTE carrier can also include other information, which is not limited here.
[0071] In the embodiment of the present application, a network element interface can be arranged between the LTE function module and the NR function module in the radio access network device, so that the LTE function module can send the cell reference signal pattern of the LTE carrier to the NR function module through the network element interface.
[0072] 204、The NR function module determines the puncturing pattern of the NR carrier according to the cell reference signal pattern of the LTE carrier.
[0073] In the embodiment of the present application, when the NR function module receives the cell reference signal pattern of the LTE carrier, it can determine the puncturing pattern of the NR carrier according to the cell reference signal pattern of the LTE carrier, that is, determine which REs in which symbols of the NR carrier do not send information, that is, determine the REs carrying zero power (ZP).
[0074] For example, according to the received cell reference signal pattern of the LTE carrier as shown in Figure 2-2 For port 0 and port 1, the NR function module needs to determine its puncturing pattern in symbols 0 / 4 / 7 / 11; and for port 2 and port 3, the NR function module needs to determine its puncturing pattern in symbols 1 / 8. On other symbols, the NR function module does not need to determine its puncturing pattern.
[0075] In some possible implementation, as shown in Figure 2-4 As shown, it is a ZP pattern specified in the current 3GPP protocol, and the NR function module can select one from the ZP patterns specified in the 3GPP protocol as the puncturing pattern of the NR carrier according to the cell reference signal pattern of the LTE carrier.
[0076] As shown in Figure 2-4As shown, Row represents the number of puncturing patterns, and its value is 1-18, representing Figure 2-4 Eighteen puncturing patterns are described in the table. Ports represents the number of antenna ports, and the value of Ports can be 1 / 2 / 4 / 8 / 12 / 16 / 24 / 32. For example, in the right graph of FIG. 1, Figure 2-4 the value of Ports is 1 / 2 / 4.
[0077] In the embodiments of the present application, density represents the spectral density, indicating that the CSI-RS is repeated once every RB, where represents rounding up, and p represents the value of density. For example, the value of density is 3 or 1, then that is, the CSI-RS is repeated once every 1 RB, that is, the CSI-RS is repeated twice every slot. For example, the value of density is 0.5, then that is, the CSI-RS is repeated once every 2 RBs, that is, the CSI-RS is repeated once every slot.
[0078] In the embodiments of the present application, CDM type represents the type of code division multiple access, and its value can be {noCDM, fd-CDM2, cdm4-FD2-TD2, cdm8-FD2-TD4}. Where, noCDM represents no code division multiple access, that is, 1 antenna port uses 1 radio frequency port. FD-CDM2 represents using 1 radio frequency port for 2 antenna ports, CDM4-FD2-TD2 represents using 1 radio frequency port for 4 antenna ports, and CDM8-FD2-TD4 represents using 1 radio frequency port for 8 antenna ports.
[0079] In the embodiments of the present application, the number of ZPs is determined first, then the value of ports is determined, and finally the ROW is determined according to the number of ZPs and the value of ports. For example, as shown in FIG. 1, Figure 2-4As shown, if the number of ZPs is 3, when ports = 1, the puncturing pattern corresponding to Row = 1 can be selected, i.e. puncturing on REs numbered 0 / 4 / 8, then the REs using shared power are 12-3 = 9; if the number of ZPs is 1, when ports = 1, the puncturing pattern corresponding to Row = 2 can be selected, i.e. puncturing on RE numbered 0, then the REs using shared power are 12-1 = 11; if the number of ZPs is 2, when ports = 2, the puncturing pattern corresponding to Row = 3 can be selected, i.e. puncturing on REs numbered 0 / 1, then the REs using shared power are 12-2 = 10; if the number of ZPs is 4, when ports = 4, the puncturing pattern corresponding to Row = 4 can be selected, i.e. puncturing on REs numbered 0 / 1 / 2 / 3, then the REs using shared power are 12-4 = 8; if the number of ZPs is 2, when ports = 4, the puncturing pattern corresponding to Row = 5 can be selected, i.e. puncturing on REs numbered 0 / 1, then the REs using shared power are 12-2 = 10. It should be noted that after the number of ZPs and the value of ports are determined, the determined Row is not uniquely determined, and there are multiple options. In some possible implementation, the selection can be based on the principle of relatively simple calculation and low complexity. For example, for symbol 4, the number of ZPs is 2, i.e. 2 REs need to be punctured, and there are row = 2 (row 2 has only one symbol, but can be repeated three times), Row = 3 and Row = 5, three options, but Row = 5 also punctures symbol 5, the complexity of Row = 2 is high, so the puncturing pattern corresponding to Row = 3 can be selected.
[0080] It should be noted that the specific puncturing mode is selected, and the NR function module can determine according to the power shared by the LTE function module and the cell reference signal pattern of the LTE carrier. For example, for symbol 4 as shown, since 4 antenna ports are used (i.e. Ports = 4), Row = 4 or Row = 5 is selected. In addition, since the total power of symbol 4 is 600, the 2 RSs of the LTE carrier occupy a total power of 200, then the LTE carrier can share a power of 400, in order to ensure that the power of each RE of symbol 4 of the NR carrier is 600 / 12 = 50, 4 REs must be punctured on the symbol 4 of the NR carrier, so the puncturing pattern corresponding to Row = 4 is selected. Figure 2-2
[0081] 205、The LTE function module shares the idle power of the LTE carrier to the NR carrier in the sharing group.
[0082] In the embodiment of the present application, after the LTE function module sends the cell reference signal pattern of the LTE carrier to the NR function module, the LTE function module can share the idle power of the LTE carrier with the NR carrier in the sharing group. In some possible implementation manners, the LTE function module can also first share the idle power of the LTE carrier with the NR carrier in the sharing group, and then send the cell reference signal pattern of the LTE carrier to the NR function module, which is not limited here. It should be noted that when the LTE function module shares the idle power of the LTE carrier with the NR carrier in the sharing group, it also indicates the values of the shared power of which symbols in the LTE carrier.
[0083] In the embodiment of the present application, the idle power of the LTE carrier is related to the symbol and the antenna port, that is, one symbol and one antenna port correspond to one idle power. For example, as shown in FIG. 2, the symbol 0 of port 0 has two RSs, each RS occupies a power of 100, and the two RSs occupy a total power of 200. Assuming that the total power is 600, the shareable power is 400; as shown in FIG. 3, the symbol 40 of port 0 has no RS. Assuming that the total power is 600, the shareable power is 600. It should be noted that the unit of power can be milliwatt (mW). Figure 2-2 Figure 2-2 In the embodiment of the present application, the idle power of the LTE carrier is related to the symbol and the antenna port, that is, one symbol and one antenna port correspond to one idle power. For example, as shown in FIG. 2, the symbol 0 of port 0 has two RSs, each RS occupies a power of 100, and the two RSs occupy a total power of 200. Assuming that the total power is 600, the shareable power is 400; as shown in FIG. 3, the symbol 40 of port 0 has no RS. Assuming that the total power is 600, the shareable power is 600. It should be noted that the unit of power can be milliwatt (mW).
[0084] 206. The NR function module sends the puncturing pattern of the NR carrier to the terminal device.
[0085] In the embodiment of the present application, when the NR function module punctures the NR carrier in the sharing group to obtain the puncturing pattern of the NR carrier, the NR function module can send the RE-level puncturing pattern of the NR carrier to the terminal device. In some possible implementation manners, the NR function module can send the radio resource control (RRC) signaling to the terminal device, and the RRC signaling carries the puncturing pattern of the NR carrier, so as to instruct the terminal device to correspond to the RE of the ZP indicated by the puncturing pattern of the NR carrier.
[0086] For example, the NR function module can use the first orthogonal frequency division multiplexing (OFDM) symbol in the time domain (FirstOFDMSymbolInTimeDomain) field in the RRC signaling to represent the symbol of the puncturing pattern, so as to inform the terminal device not to demodulate the PDSCH data on the corresponding RE of the symbol. For example, as shown in FIG. 4, the NR function module can use the first OFDM symbol in the time domain (FirstOFDMSymbolInTimeDomain) field in the RRC signaling to indicate that the terminal device does not demodulate the PDSCH data on the RE corresponding to the first OFDM symbol in the time domain (FirstOFDMSymbolInTimeDomain) field. Figure 2-5 As shown, resourceMapping (for indicating the index of RE carrying ZP) in ZP-Channel State Information (CSI)-RS-Resource (resource) is resource index, the name of SEQUENCE of its sequence is CSI-RS-ResourceMapping. As shown in the following table, in the CSI-RS-ResourceMapping information element corresponding to CSI-RS-ResourceMapping, the ZP pattern (i.e. the puncturing pattern of the NR carrier, the value of index Row), the number of ZP ports (ZP port number, for example 1 / 2 / 4 / 8 / 12 / 16 / 24 / 32), the starting position of the ZP pattern (for example 0..13 or 2..12, in the case of a larger port, there can be 2 starting positions), the code division mapping mode (for example noCDM, fd-CDM2, cdm4-FD2-TD2, CDM8-FD2-TD4), the density of the ZP pattern (i.e. density), the RB range of the ZP pattern, and other information are indicated. Figure 2-6
[0087] 207、The NR function module performs power allocation on the shared power according to the puncturing pattern of the NR carrier.
[0088] In some possible implementation manners, for a symbol, the NR function module can first allocate the shared power to each RE of the symbol in an average manner, then determine the REs (i.e. ZP) to which no power is allocated according to the puncturing pattern of the NR carrier and recover the power on the REs, and then uniformly allocate the recovered power to other REs (i.e. PDSCH resource units for transmission).
[0089] The following is an example, taking a single symbol and a single antenna port as an example, to separately control the power and allocate the shared power. As shown in the following table, in the CSI-RS-ResourceMapping information element corresponding to CSI-RS-ResourceMapping, the ZP pattern (i.e. the puncturing pattern of the NR carrier, the value of index Row), the number of ZP ports (ZP port number, for example 1 / 2 / 4 / 8 / 12 / 16 / 24 / 32), the starting position of the ZP pattern (for example 0..13 or 2..12, in the case of a larger port, there can be 2 starting positions), the code division mapping mode (for example noCDM, fd-CDM2, cdm4-FD2-TD2, CDM8-FD2-TD4), the density of the ZP pattern (i.e. density), the RB range of the ZP pattern, and other information are indicated. Figure 2-7 As shown, the shared power is 400 on symbol 4. First, 400 power is allocated to 12 REs, each RE gets 400 / 12 ~ 33.33 power. Then, the NR function module determines that symbol 4 has 4 ZPs (i.e. REs without power allocation), so the NR function module recovers the power on the REs corresponding to the 4 ZPs, i.e. gets 400 / 12*4 ~ 133.33 power. Next, the NR function module evenly allocates the 133.33 power to the remaining 12-4 = 8 REs, so each of the 8 REs is allocated 400 / 12*4 / 8 = 16.67 power more. Then, each of the 8 REs can get 400 / 12 + 400 / 12*4 / 8 = 33.33 + 16.67 = 50 power. So the power spectral density of each RE in symbol 4 and each RE in symbol 10 is equal. In some possible implementation, the NR function module can re-rate match the REs after power sharing.
[0090] For another example, on symbol 10, the shared power is 600. First, 600 power is allocated to 12 REs, each RE gets 600 / 12 = 50 power. Then, the NR function module determines that symbol 4 has 0 ZPs (i.e. REs without power allocation), so the NR function module does not need to recover the power on the REs corresponding to the ZPs, i.e. the 12 REs can get 600 / 12 = 50 power in total.
[0091] In some possible implementation, the NR function module can calculate the number of ZPs in the following way. Suppose that on a symbol, there are 12 REs, RE1 ~ RE12. After the NR function module completes the puncturing pattern of the NR carrier, first, the number of REs carrying PDSCH is calculated:
[0092]
[0093] wherein CsirsReNum represents the number of all REs carrying ZPs; CrsLocation represents the value corresponding to the position index of the RE corresponding to the RS in the cell reference signal pattern of the scheduled LTE carrier; PCcrs represents the CRS PC offset, and the CRS PC offset represents the ratio of the power of the RE carrying the RS to the power of the RE carrying PDSCH, in units of decibel (dB).
[0094] As shown in Table 1 below, the relationship between the CRS PC offset and the number of ZPs:
[0095]
[0096] If CRS PC offset is -3, it means that the power of RE carrying RS is 0.5 times the power of RE carrying PDSCH, and the ZP number is 1; if CRS PC offset is 0, it means that the power of RE carrying RS is 1 times the power of RE carrying PDSCH, and the ZP number is 2; if CRS PC offset is 3, it means that the power of RE carrying RS is 2 times the power of RE carrying PDSCH, and the ZP number is 4; if CRS PC offset is 6, it means that the power of RE carrying RS is 4 times the power of RE carrying PDSCH, and the ZP number is 8.
[0097] In the embodiment of the present application, after CsirsReNum is obtained, the power control factor (unit: dB) of RE carrying PDSCH can be calculated as follows:
[0098] RePwrFactor = 10^(12 / (12-CsirsReNum))
[0099] For example, if CsirsReNum = 4, then RePwrFactor = 10*log 10 (12 / (12-CsirsReNum))≈1.76dB, i.e. 1.5 times. Then, the NR function module allocates 1.5 times of 33.33 power to each of the 8 REs, i.e. 33.33*1.5=50, to complete the power allocation of each RE in the symbol of the NR carrier.
[0100] 208、The terminal device demodulates according to the puncturing pattern of the NR carrier.
[0101] In the embodiment of the present application, after the terminal device receives the puncturing pattern of the NR carrier sent by the NR function module, it can demodulate according to the RE-level puncturing pattern of the NR carrier.
[0102] In some possible implementation manners, a simulation experiment can be set. It is assumed that users are uniformly distributed in a 10-megahertz (M) cell. The power offset of the REs carrying RS in the LTE carrier relative to the REs carrying PDSCH in the same symbol is 3 dB (that is, the power of the former is twice the power of the latter). If the LTE carrier shares 66% power with the NR carrier, the cell throughput of the NR carrier in the simulation experiment is 34.29 Mbps. If the LTE carrier shares 100% power with the NR carrier, the cell throughput of the NR carrier in the simulation experiment is 42.81 Mbps, and the gain is 24.85%=(42.81-34.29) / 34.29. The resource loss after puncturing the NR carrier is 16 (the number of ZPs) / (12*12 (the total number of REs in a single symbol))=11.11%, and therefore the overall gain is 24.85%-11.11%=13.75%.
[0103] The application is used for a wireless access device including an NR function module and an LTE function module, and the NR function module and the LTE function module share a radio frequency channel. The NR function module first acquires a cell reference signal pattern of the LTE carrier, and then determines a puncturing pattern of the NR carrier according to the cell reference signal pattern of the LTE carrier, that is, the power of some REs in a symbol of the NR carrier is 0, so that when the NR function module acquires shared power of the LTE carrier and performs power allocation on the NR carrier according to the puncturing pattern of the NR carrier and the shared power, the power density between the symbols of the NR carrier is ensured to be equal.

[0105] 301. The LTE function module adds the LTE carrier into a power sharing group.
