Description
Technical Field
The present disclosure relates to the field of communications technologies, and in particular, to a power sharing method and a wireless access device.
Background
The service of the long term evolution technology (long term evolution, LTE) and the New Radio (NR) has the characteristic of strong burstiness, so that the radio frequency module of the base station has the condition of instantaneous full power or instantaneous idle power.
Currently, an LTE functional module and an NR functional module are simultaneously provided on one base station, and the two functional modules share a power amplifier on a radio frequency module channel. Because the LTE service and the NR service have the characteristic of strong burstiness, the LTE functional module and the NR functional module are unbalanced in use of the power amplifier at the same moment, so that the functional module with the instantaneous idle function can share surplus power to the functional module with the instantaneous full function, and the use efficiency of the power is improved. For example, the LTE functional module shares power to the NR functional module or the NR functional module shares power to the LTE functional module.
However, when the LTE functional module shares power with the NR functional module, in order to guarantee signal measurement and user access of a basic cell using LTE, power of a Reference Signal (RS) must be reserved, and cannot be shared, for example, a cell-specific reference signal (CRS). Then, among the multiple symbols of one slot of LTE, some symbols have REs that need to carry RS, and then the power shared for the NR functional module needs to be subtracted by the power of the Resource Element (RE) of the RS; no REs that need to carry RSs exist in other symbols, then the full power can be shared for the NR function modules.
Since the power shared by the symbols of REs that need to carry RSs and those that do not need to carry RSs are not equal, the number of REs that use these powers on the NR function module side is the same, resulting in unequal power densities between these symbols. According to link emulation demodulation, if the power densities between symbols differ by 2dB, then at modulation and coding strategies (modulation and coding scheme, MCS) >16, the cyclic redundancy check (cyclic redundancy check, CRC) will be demodulated incorrectly, resulting in lower MCS usage and lower transmission efficiency.

Furthermore, various aspects or features of the present application may 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 encompasses 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, or magnetic strips, etc.), optical disks (e.g., compact disk, CD, digital versatile disk, digital versatile disc, DVD, etc.), smart cards, and flash memory devices (e.g., erasable programmable read-only memory, EPROM), cards, sticks, or key drives, 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.
Because of the characteristic of strong burstiness of LTE service and NR service, the LTE functional module and the NR functional module use the power amplifier unevenly in the same moment, so that the functional module with the instantaneous idle function can share surplus power to the functional module with the instantaneous full function, and the use efficiency of the power is improved. For example, the LTE functional module shares power to the NR functional module or the NR functional module shares power to the LTE functional module.
However, when the LTE functional module shares power with the NR functional module, in order to ensure signal measurement of a cell basically using LTE and user access, reference Signal (RS) power must be reserved and cannot be shared. Then, among the multiple symbols of one slot of LTE, some symbols have REs that need to carry RS, and then the power shared for the NR function module needs to be subtracted from the power of the REs of the RS; no REs that need to carry RSs exist in other symbols, then the full power can be shared for the NR function modules.
For example, as shown in fig. 1-2, the symbol with REs that need to carry RSs is symbol 0/4/7/11, and the symbol without REs that need to carry RSs is symbol 1/2/3/5/6/8/9/10/12/13. According to a typical configuration of the present network, the power of the REs carrying the RS is 3dB higher than the function of the REs carrying the PDSCH with the same symbol (i.e., the power of the RS is 2 times the power of the REs). Then, in the symbol carrying RSs, for example, symbol 4, the total power is 600, and the total power required by 2 RSs is 200, and then the total power of the remaining REs is 400, i.e. the shared power is 400. And there is no symbol that needs to carry RS, for example, symbol 10, the total power is 600, and the total power of RS is 0, then the total power of RE is 600, i.e. the shared power is 600.
Then the power spectral density is 400/12 on symbol 4 of the NR power module and 600/12 on symbol 10, i.e. 10 log difference 10 (600/400) =1.76 dB. According to the simulation demodulation of the link, if the difference between symbols is 2dB, the method is characterized in that>At 16, the CRC may be corrupted, resulting in a lower MCS to be used, resulting in lower transmission efficiency. Currently, if the inter-symbol power densities are different, power scaling is performed. For example, using only 400 for power on symbol 10, the power of symbol 10 and symbol 4 is achievedThe densities are equal resulting in underutilization of power during sharing.
Therefore, the application provides a power sharing method and wireless access equipment, which are used for wireless access equipment comprising an NR functional module and an LTE functional module sharing a radio frequency channel, and are used for carrying out power sharing on the NR functional module and the LTE functional module.
The wireless access device comprises an NR functional module and an LTE functional module, wherein the NR functional module and the LTE functional module share a radio frequency channel. The NR functional module firstly 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, even if the power of some RE of the symbols in the NR carrier is 0, the NR functional module acquires the shared power of the LTE carrier, and performs power distribution on the NR carrier according to the puncturing pattern of the NR carrier and the shared power, so that the equal power density among the symbols of the NR carrier is ensured.
For example, referring to fig. 2-1, an embodiment one of a power sharing method provided in the present application includes the following steps:
201. the LTE functional module adds the LTE carrier into the power sharing group.
In the embodiment of the present application, the LTE functional module may add the LTE carrier to be shared into the power sharing group. It should be noted that an LTE carrier may include a plurality of slots, one slot may include a plurality of symbols, and each symbol may include a plurality of REs. For example, the LTE carrier is 1 slot, and 1 slot includes 2 Resource Blocks (RBs), and one RB includes 7 symbols, each symbol including 12 REs.
202. The NR function module adds an NR carrier to the power-sharing group.
In the embodiment of the application, the NR function module may add the NR carrier to the power sharing group. It should be noted that, the NR carrier may also include a plurality of slots, and one slot may include a plurality of symbols, and each symbol may include a plurality of REs. For example, the LTE carrier is 1 slot, and 1 slot includes 2 Resource Blocks (RBs), and one RB includes 7 symbols, each symbol including 12 REs.
And when the LTE carrier and the NR carrier are added to the same power sharing group at the same time, the LTE carrier and the NR carrier 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 fixed value, for example 600 (milliwatts, mW).
For example, as shown in fig. 2-2, there is a schematic diagram of one slot in the LTE carrier and one slot in the NR carrier. Wherein, 2 RSs are in symbol 4 of the LTE carrier, the power of each RS is 100, and the total power of 2 RSs is 200. If the upper power limit of the radio frequency channel is 600, then 600-200=400 of the power still remains in symbol 4 of the LTE carrier, which can be shared with the NR carrier. Wherein, there are 0 RSs in symbol 10 of the LTE carrier, and then 600 power remains in symbol 6 of the LTE carrier, which can be shared to the NR carrier.
203. The LTE functional module sends a cell reference signal pattern of the LTE carrier to the NR functional module.
In the embodiment of the present application, in order for the NR functional module to calculate the puncturing pattern of the NR carrier, the LTE functional module may send the cell reference signal pattern of the LTE carrier to the NR functional module.
For example, as shown in fig. 2-3, a cell reference signal pattern for 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 may include which symbols in the LTE carrier in each antenna port carry RSs, and the number of RSs carried on each symbol. For example, in port 0,2 RSs are carried on symbols 0/4/7/11, respectively. In some possible implementations, the cell reference signal pattern of the LTE carrier may also include the power of a single RS, e.g., the power of an RS is 100. In some possible implementations, the cell reference signal pattern of the LTE carrier further includes REs of 0 power. For example, in port 0, REs with 0 power on symbols 0/1/4/7/8/11, respectively. These REs are used to transmit RSs on other antenna ports. In some possible implementations, the message of the cell reference signal pattern of the LTE carrier may also include other information, which is not limited herein.
In the embodiment of the present application, a network element interface may be disposed between an LTE functional module and an NR functional module in a radio access network device, so that the LTE functional module may send a cell reference signal pattern of an LTE carrier to the NR functional module through the network element interface.
204. The NR functional module determines a puncturing pattern of the NR carrier according to the cell reference signal pattern of the LTE carrier.
In this embodiment of the present application, after the NR functional module receives the cell reference signal pattern of the LTE carrier, the puncture pattern of the NR carrier may be determined according to the cell reference signal pattern of the LTE carrier, i.e. it is determined which REs of which symbols in the NR carrier are REs that do not transmit information, i.e. it is determined that REs carrying zero-power (ZP).
For example, according to the cell reference signal pattern of the received LTE carrier as shown in fig. 2-2, for port 0 and port 1, in symbol 0/4/7/11, the NR function module needs to determine its puncturing pattern; whereas for port 2 and port 3, in symbol 1/8, the NR function module needs to determine its puncturing pattern. On other symbols, the NR function module does not need to determine its puncturing pattern.
In some possible implementations, as shown in fig. 2-4, for the ZP pattern specified in the current 3GPP protocol, the NR function module may select one from the ZP patterns specified in the 3GPP protocol according to the cell reference signal pattern of the LTE carrier as the puncturing pattern of the NR carrier.
As shown in fig. 2 to 4, row represents the number of the punching pattern, which has a value of 1 to 18, and represents 18 kinds of punching patterns described in fig. 2 to 4. Ports represent the number of antenna Ports, where the value of Ports may be 1/2/4/8/12/16/24/32. For example, in the right hand diagrams of FIGS. 2-4, the value of Ports is 1/2/4.
In the present embodiment, density represents spectral density, representing every otherThe CSI-RS is repeated 1 time in RB, wherein +.>Representing a rounding upρ represents the value of density. For example, the Density has a value of 3 or 1, then +.>I.e., every 1 RB, the CSI-RS is repeated 1 time, i.e., every slot, the CSI-RS is repeated 2 times. For example, if the Density value is 0.5, thenI.e., every 2 RBs, the CSI-RS is repeated 1 time, i.e., every slot, the CSI-RS is repeated 1 time.
In the embodiment of the present application, CDM type represents a code division multiple access type, and the value thereof may be { nocm, FD-CDM2, CDM4-FD2-TD2, CDM8-FD2-TD4}. Wherein nocm indicates that no code division multiple access is performed, i.e., 1 antenna port uses 1 radio frequency port. FD-CDM2 means 1 radio frequency port is used at 2 antenna ports, CDM4-FD2-TD2 means 1 radio frequency port is used at 4 antenna ports, CDM8-FD2-TD4 means 1 radio frequency port is used at 8 antenna ports.
In the embodiment of the application, firstly, the number of ZPs is determined, 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. 2-4, if the number of ZPs is 3, when ports=1, a puncturing pattern corresponding to row=1 may be selected, that is, puncturing on REs numbered 0/4/8, then there are 12-3=9 REs that need to use shared power; if the number of ZPs is 1, when ports=1, a puncturing pattern corresponding to row=2 may be selected, that is, puncturing on REs with number 0, there are 12-1=11 REs needed to use shared power; if the number of ZPs is 2, when ports=2, a puncturing pattern corresponding to row=3 can be selected, that is, puncturing is performed on REs numbered 0/1, and there are 12-2=10 REs that need to use shared power; if the number of ZPs is 4, when ports=4, a puncturing pattern corresponding to row=4 may be selected, that is, puncturing on REs numbered 0/1/2/3, and there are 12-4=8 REs needed to use shared power; if the number of ZPs is 2, when ports=4, a puncturing pattern corresponding to row=5 may be selected, that is, puncturing on REs numbered 0/1, there are 12-2=10 REs that need to use shared power. It should be noted that, when the number of ZPs and the value of ports are determined, the determined Row is not uniquely determined, and there are a plurality of alternatives. In some possible implementations, the selection may be based on computationally simpler and less complex principles. For example, for symbol 4, the number of zps is 2, that is, 2 REs need to be punctured, there are row=2 (Row 2 is only 1 symbol but can be repeated 3 times), row=3 and row=5, and three are optional, but row=5 also punctures symbol 5, and the complexity of row=2 is high, so a puncturing pattern corresponding to row=3 can be selected.
It should be noted that, which puncturing mode is specifically selected, the NR function module may be determined 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 shown in fig. 2-2, since 4 antenna Ports (i.e., ports=4) are used, i.e., either row=4 or row=5 is selected. In addition, since the total power of symbol 4 is 600 and the total power occupied by 2 RSs of the LTE carrier is 200, the LTE carrier can share 400 power, and 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 symbol 4 of the NR carrier, so a puncturing pattern corresponding to row=4 is selected.
205. And the LTE functional module shares the idle power of the LTE carrier to the NR carrier in the shared group.
In this embodiment of the present application, after the LTE functional module sends the cell reference signal pattern of the LTE carrier to the NR functional module, the LTE functional module may share the idle power of the LTE carrier to the NR carrier in the shared group. In some possible implementations, the LTE functional module may also first share the idle power of the LTE carrier to the NR carriers in the shared group, and then send the cell reference signal pattern of the LTE carrier to the NR functional module, which is not limited herein. It should be noted that, when the LTE functional module shares the idle power of the LTE carrier to the NR carrier in the shared group, the LTE functional module also indicates the values of the shared power of which symbols in the LTE carrier.
In the embodiment of the present application, the idle power of the LTE carrier is related to a symbol and an antenna port, i.e. one symbol and one antenna port correspond to one idle power. For example, as for symbol 0 of port 0 in fig. 2-2, since there are 2 RSs, each occupying 100 power, the total occupied power of two RSs is 200, and if the total power is 600, the sharable power is 400; as with symbol 40 of port 0 in fig. 2-2, since there is no RS, if the total power is 600, then the power that can be shared is 600. It should be noted that the unit of power may be milliwatts (mW).
206. The NR function module transmits a puncturing pattern of an NR carrier to the terminal device.
In this embodiment of the present application, when the NR functional module punctures the NR carriers in the shared group, after the puncturing pattern of the NR carriers is obtained, the puncturing pattern of the RE level of the NR carriers may be sent to the terminal device. In some possible implementations, the NR functional module may send radio resource control (radio resource control, RRC) signaling to the terminal device, where the RRC signaling carries a puncturing pattern of the NR carrier, so as to indicate REs corresponding to ZPs indicated by the puncturing pattern of the NR carrier by the terminal device.
For example, the NR function characterizes the symbols of the puncture pattern by a first orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) symbol (firstofdm symbol) field in the time domain of RRC signaling to inform the terminal device not to demodulate PDSCH data on the corresponding REs of the symbols. As shown in fig. 2-5, the sequence (sequence) is named CSI-RS-resource mapping, which is a resource index (index for indicating REs carrying ZP) in ZP-channel state information (channel state information, CSI) -RS-resources (resource). As shown in fig. 2 to 6, in the CSI-RS-resource mapping information element (information element) corresponding to the CSI-RS-resource mapping, information such as ZP pattern (i.e., puncturing pattern of NR carrier, index is a value of Row), number of antenna ports of ZP (ZP port number, for example 1/2/4/8/12/16/24/32), ZP pattern start position (for example 0..13 or 2..12, where there may be 2 start positions in case of a large port), code division mapping manner (for example, nocm, FD-CDM2, CDM4-FD2-TD2, CDM8-FD2-TD 4), density (i.e., density) of ZP pattern, RB range of ZP pattern, etc. is indicated.
207. The NR functional module performs power allocation on the shared power according to the puncturing pattern of the NR carrier.
In some possible implementations, for a symbol, the NR function module may first allocate shared power equally to the REs of the symbol, then determine REs that are not allocated power (i.e., ZPs) according to the puncturing pattern of the NR carrier and reclaim power on those REs. The NR function module then allocates the reclaimed power evenly to other REs (i.e., PDSCH resource units for transmission).
In the following, taking a single antenna port with a single symbol as an example, power control is performed separately to allocate the shared power. As shown in fig. 2-7, on symbol 4, the shared power is 400. First 400 power is allocated to 12 REs, each resulting in a power of 400/12≡33.33. Then, the NR functional module determines that symbol 4 has 4 ZPs (i.e. REs to which power is not allocated), and then the NR functional module recovers the power on REs corresponding to the 4 ZPs, i.e. 400/12×4≡133.33. Next, the NR function module allocates 133.33 power equally to the remaining 12-4=8 REs, resulting in 400/12×4/8=16.67 power allocated per each of the 8 REs. Then each of these 8 REs may get a power of 400/12+400/12 x 4/8=33.33+16.67=50. Then the power spectral density of each RE in symbol 4 and each RE in symbol 10 are equal. In some possible implementations, when the NR function module can RE-rate match the RE after power sharing.
Also for example, on symbol 10, the shared power is 600. 600 power is first allocated to 12 REs, each resulting in 600/12=50 power. Then, the NR functional module determines that symbol 4 has 0 ZPs (i.e. REs to which no power is allocated), and the NR functional module does not need to recover the power on the REs corresponding to the ZPs, so as to obtain a total of 600/12=50 of the 12 REs.
In some possible implementations, the NR function module may calculate the number of ZPs in the following manner. Let us assume that on one symbol, there are 12 REs, RE1 to RE12, respectively. After the NR functional module completes the puncturing pattern of the NR carrier, the number of REs carrying PDSCH is first calculated:
wherein CsirsReNum represents the number of REs carrying ZP; crsLocation is indicated as a value corresponding to a position index of an RE corresponding to RS in a cell reference signal pattern of a scheduled LTE carrier; PCcrs represents the CRS PC bias, which represents the ratio of the power of the RE carrying the RS to the power of the RE carrying the PDSCH in decibels (dB).
Table 1 below shows the relationship between CRS PC bias and ZP number:
wherein, the value of the CRS PC bias is-3, which indicates that the power of the RE carrying RS is 0.5 times that of the RE carrying PDSCH, and the ZP number is 1; the CRS PC bias has a value of 0, which indicates that the power of the REs carrying the RS is 1 time that of the REs carrying the PDSCH, and the ZP number is 2; the CRS PC bias has a value of 3, which indicates that the power of the REs carrying the RS is 2 times that of the REs carrying the PDSCH, and the ZP number is 4; the CRS PC bias has a value of 6, indicating that the power of the REs carrying the RS is 4 times the power of the REs carrying the PDSCH, and the ZP number is 8.
In the embodiment of the present application, after CsirsReNum is obtained, the power control factor (unit dB) of the RE carrying PDSCH may be calculated:
RePwrFactor=10^(12/(12-CsirsReNum))
for example, csirsrenum=4, then repwrfactor=10×log 10 (12/(12-CsinReNum)). Apprxeq.1.76 dB, i.e., 1.5 times. Then, the NR function module allocates 1.5 times of the power of 33.33 to each of the 8 REs, that is, 33.33×1.5=50, to complete the power allocation of each RE in the symbol of the NR carrier.
208. The terminal device performs corresponding demodulation according to the puncturing pattern of the NR carrier.
In this embodiment of the present application, after the terminal device receives the puncturing pattern of the NR carrier sent by the NR functional module, corresponding demodulation may be performed according to the RE-level puncturing pattern of the NR carrier.
In some possible implementations, simulation experiments may be set up. It is assumed that users are evenly distributed in 10 megacells (M). The power offset of the REs carrying RSs in the LTE carrier is 3dB relative to the REs carrying PDSCH of the same symbol (i.e. the power of the former is 2 times the power of the latter). If the LTE carrier shares 66% of power for the NR carrier, the cell throughput rate under the NR carrier in the simulation experiment is 34.29Mbps. If the LTE carrier shares 100% power for the NR carrier, the cell throughput rate under the NR carrier in the simulation experiment is 42.81Mbps, and the gain is 24.85% = (42.81-34.29)/34.29. The resource loss after puncturing the NR carrier is 16 (number of ZPs)/(12×12 (total number of REs in a single symbol))=11.1%, so the overall gain is 24.85% -11.11% =13.75%.
The wireless access device comprises an NR functional module and an LTE functional module, wherein the NR functional module and the LTE functional module share a radio frequency channel. The NR functional module firstly 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, even if the power of some RE of the symbols in the NR carrier is 0, the NR functional module acquires the shared power of the LTE carrier, and performs power distribution on the NR carrier according to the puncturing pattern of the NR carrier and the shared power, so that the equal power density among the symbols of the NR carrier is ensured.
