[0070] The technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0071] The technical solutions of the embodiments of the present application can be applied to various communication systems, for example: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD) system, Universal Mobile Telecommunication System (UMTS) system, Worldwide Interoperability for Microwave Access (WiMAX) system or future 5G (also called New Radio (NR)) system.

[0072] The network device mentioned in the embodiment of the present application may be a device that communicates with a terminal device. The network device may provide communication coverage for a specific geographical area, and may communicate with a terminal device (e.g., UE) located in the coverage area. Optionally, the network device may be a base station (Base Transceiver Station, BTS) in a GSM system or a CDMA system, or a base station (NodeB, NB) in a WCDMA system, or an evolved base station (Evolutional Node B, eNB or eNodeB) in an LTE system, or a wireless controller in a cloud radio access network (Cloud Radio Access Network, CRAN), or the network device may be a relay station, an access point, different antenna panels (Antenna panels) of the same base station, a transmitting-receiving point (TRP), a vehicle-mounted device, a wearable device, a network side device in a future 5G network, or a network device in a future evolved public land mobile network (Public Land Mobile Network, PLMN), etc.

[0073] The terminal device mentioned in the embodiment of the present application may be mobile or fixed. Optionally, the terminal device may refer to an access terminal, a user equipment (UE), a user unit, a user station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent or a user device. The access terminal may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G network, or a terminal device in a future evolved PLMN, etc.

[0074] In the NR system, ultra-reliable low-latency communication (URLLC) services have better reliability and lower latency.

[0075] URLLC services can be used in fields with more stringent requirements, such as industrial Internet and autonomous driving.

[0076] In order to meet the low latency requirement, the transmission time of URLLC services can be reduced (for example, by introducing mini-slots and reducing retransmissions).

[0077] In the NR system, one time slot is defined as 7 or 14 symbols, and the number of symbols may vary for different subcarrier spacings.

[0078] At the same time, in the NR system, enhanced mobile broadband (eMBB) can also be carried out. eMBB service is a broadband service that includes various common services such as browsing and video.

[0079] For a UE capable of supporting both eMBB and URLLC, in some application scenarios, eMBB uplink data and URLLC uplink data may be transmitted at the same time.

[0080] For example Figure 1 He Ru Figure 2 As shown, the uplink URLLC transmission (referred to as channel U) and the uplink eMBB transmission (referred to as channel e) overlap in time. The transmission power required by the two channels is recorded as P_U and P_e respectively. If P_U+P_e>P_max, power control is required.

[0081] Optionally, since the URLLC service has better latency / reliability requirements, it has a higher priority in power allocation, that is, power is usually allocated to the URLLC service first, and the power allocated to the eMMB service at this time is less than the power P_e it requires.

[0082] URLLC services have high latency requirements and a short interval between data transmission and actual transmission. Therefore, when a UE starts an eMBB transmission, it is uncertain whether there will be URLLC transmissions in parallel during the transmission process.

[0083] In order to effectively solve the power allocation problem during concurrency, there are two solutions:

[0084] Method 1: Semi-static cap allocation: The network configures a power cap for eMBB and / or URLLC through signaling.

[0085] Method 2: When concurrency occurs, UEs are relatively dynamically allocated between eMBB and URLLC according to certain rules.

[0086] In method 2, the following situation may occur: in an eMBB transmission, the transmit power of different parts is different. Figure 2As shown, the transmission power required for eMBB is P_e. When there is no concurrent transmission with URLLC (for example, time period t2), the UE can use power P_e to transmit; when concurrency occurs (for example, time period tl), part of the power may be allocated to URLLC transmission, resulting in the UE only being able to use power P_1 to send eMBB (P_1<P_e).

[0087] In this case, if the network side is unaware of the power change, the performance of channel estimation, data demodulation (16QAM, 64QAM, ...) may be significantly degraded.

[0088] Therefore, in response to this and similar problems, the embodiments of the present application provide the following solutions.

[0089] Figure 3 1 is a schematic flow chart of a communication method 100 according to an embodiment of the present application. The method 100 includes at least part of the following contents.

[0090] In 110, the terminal device determines power information of uplink transmission of a first service performed in a first time period, wherein the terminal device simultaneously performs uplink transmission of the first service and at least one second service in the first time period.

[0091] Optionally, the priority of the first service is higher than the priority of the second service.

[0092] Optionally, the first service is an eMBB service; and the second service is a URLLC service.

[0093] It should be understood that the first service and the second service may also be services of other two categories, or two different services.

[0094] It is also understood that in the embodiments of the present application, although the first service and the second service are described, it does not mean that only two services are transmitted simultaneously. For example, the first service may include multiple services, or the second service may include multiple services, or other third services may exist simultaneously.

[0095] Optionally, the power information is used to indicate: whether the actual power used by the terminal device for uplink transmission of the first service in the first time period is the same as the specific power; and / or the difference between the actual power used by the terminal device for uplink transmission of the first service in the first time period and the specific power.

[0096] Specifically, the terminal device can carry information related to f(P_e, P_1) in the URLLC transmission. f is a function whose value can be taken in the following ways:

[0097] Mode 1: P_e is the same as P_1, or different from P_1. That is, whether the power of eMBB changes during the transmission process.

[0098] In this mode 1, it is possible to implicitly indicate whether the power of the eMBB has changed during the current transmission. If there is no corresponding field in the transmission message of the second service, it means that the power has not changed. If there is a corresponding field in the transmission message of the second service, it means that the power has changed. Alternatively, it is possible to indicate whether the power has changed in a displayed manner, for example, there is corresponding information in the transmission message of the second service to indicate whether the power has changed.

[0099] Mode 2: f is a function related to the difference P_1-P_e. For example, f is a quantized value of P_1-P_e, or an identifier corresponding to the value range of P_1-P_e.

[0100] In 120, the terminal device sends the power information to the network device during uplink transmission of the second service in the first time period.

[0101] Optionally, the power information is carried in a first message sent by the terminal device to the network device, and the first message also carries data or other information of the second service.

[0102] In 130, the network device receives power information sent by the terminal device during uplink transmission of the second service performed by the terminal device in the first time period, and the power information is power information of uplink transmission of the first service performed by the terminal device in the first time period.

[0103] In 140, the network device demodulates the first service according to the power information.

[0104] Optionally, in an embodiment of the present application, the terminal device can perform channel estimation to obtain the actual power used to transmit the second service, and can obtain the actual transmission power used for the first service based on the actual power used to transmit the second service and the maximum transmission power available to the terminal device.

[0105] In this solution, the terminal device can directly notify the network device of the transmission power actually used by the first service.

[0106] At this time, the network device may demodulate the first service received in the first time period according to the transmission power actually used by the first service.

[0107] Alternatively, the difference between the transmission power actually used by the first service and the specific power is notified to the network device.

[0108] At this time, the network device can combine the demodulation reference signal (DMRS) calculated for the second service at a specific power and the difference to obtain a new DMRS, and use the new DMRS to demodulate the first service received in the first time period.

[0109] Specifically, the terminal device can carry information related to f(P_e, P_1) in the URLLC transmission, where f is a function whose value is the above-mentioned method 2. After the network side detects the information, it learns the power difference between P_e and P_1, and demodulates the eMBB transmission based on this information.

[0110] Alternatively, the terminal device may determine whether the transmission power actually used by the first service is the same as the specific power, and notify the network device of the same or different information.

[0111] At this time, if the actual transmission power used by the first service is the same as the specific power, the network device can demodulate the first service received in the first time period by using the demodulation reference signal DMRS calculated for the second service at the specific power.

[0112] Specifically, the terminal device can carry information related to f(P_e, P_1) in the URLLC transmission, where f is a function whose value is the above-mentioned method 1, that is, P_e is the same as P_1, or different.

[0113] For example, the range of the difference P_e-P_1 is in a specified set. After receiving the URLLC transmission, the network side demodulates to the corresponding indication: if the power of the eMMB does not change, the network side demodulates normally; if the power of the eMMB changes, the network uses a certain method to determine which of the specified sets the difference P_e-P_1 belongs to, and then demodulates the eMBB transmission this time according to the determination result.

[0114] If the actual transmission power used by the first service is different from the specific power, the network device can use the demodulation reference signal DMRS calculated for the second service at the specific power, and estimate the difference between the actual transmission power used and the specific power to obtain a new DMRS, and use the new DMRS to demodulate the first service received in the first time period.

[0115] Optionally, based on the power of the terminal device transmitting the second service to the network device in the first time period and a set of power differences corresponding to the first service, the power information of the uplink transmission of the first service to be performed in the first time period is determined; wherein the power difference set includes an optional difference between the actual power used by the terminal device for the uplink transmission of the first service and the specific power.

[0116] Specifically, the terminal device can perform channel estimation to obtain the actual power used to transmit the second service, and can obtain the actual transmission power used for the first service based on the actual power used to transmit the second service and the maximum transmission power available to the terminal device and the optional difference in the difference set.

[0117] Optionally, the specific power is the power used for transmitting the first service alone before the first time period and adjacent to the first time period. Figure 2 As shown, the first time period may be t1, and the specific power may be the power used for transmitting the first service in the time period t2.

[0118] Optionally, the difference value set is preset on the terminal device, or is configured for the terminal device by the network device.

[0119] Optionally, the difference information includes the quantized value or an identifier of a range to which the difference belongs.

[0120] In one implementation, the difference information includes a quantized value; and according to the power information, the network device demodulates the first service.

[0121] Specifically, the network device may use the demodulation reference signal DMRS calculated for the second service at a specific power and the difference quantization value to obtain a new DMRS, and use the new DMRS to demodulate the first service received in the first time period.

[0122] In one implementation, the difference information includes an identifier of a range to which the difference belongs; and the network device demodulates the first service using the difference included in the range.

[0123] Specifically, the range to which the difference value belongs may include multiple difference values, and the network device may use the multiple difference values ​​to sequentially demodulate the first service received in the first time period to directly demodulate the first service.

[0124] Therefore, in an embodiment of the present application, when the terminal device simultaneously performs uplink transmission of a first service and at least one second service within a first time period, during the transmission of the first service within the first time period, power information of the uplink transmission of the first service within the first time period is sent to the network device, so that the network device can accurately obtain the power information of the first service when the first service and the second service are simultaneously performed, thereby correctly demodulating the first service and improving communication performance.

[0125] Figure 4is a schematic flow chart of a wireless communication method 200 according to an embodiment of the present application. The method 200 includes at least part of the following contents.

[0126] In 210, the terminal device determines the power used for transmission of the first service based on a power difference set corresponding to the first service and the power used for transmission of the second service performed by the terminal device in the first time period, the power difference set including an optional difference between an actual power used by the terminal device for uplink transmission of the first service and a specific power.

[0127] Optionally, the second service has a higher priority than the first service.

[0128] Optionally, the first service is an enhanced mobile broadband eMBB service; the second service is a low-latency and high-reliability scenario URLLC service.

[0129] Specifically, the terminal device can perform channel estimation to obtain the actual power used to transmit the second service, and can obtain the actual transmission power used for the first service based on the actual power used to transmit the second service and the maximum transmission power available to the terminal device and the optional difference in the difference set.

[0130] In 220, according to the determined power, the terminal device transmits the second service within the first time period.

[0131] In 230, when the terminal device transmits a first service and a second service to the network device simultaneously within a first time period, the network device obtains a power difference value set corresponding to the first service.

[0132] In 240, the network device demodulates the first service in the first time period according to the power difference set, wherein the power difference set includes an optional difference between an actual power used by the terminal device for uplink transmission of the first service and the specific power.

[0133] Specifically, when the terminal device transmits URLLC and eMMB concurrently, it may not carry the power information described in the above method 100. The network device can determine which of the specified sets the difference P_e-P_1 belongs to based on the received signal, and then demodulate the eMBB transmission this time based on the judgment result; or, the network side uses an element in the specified set according to a certain method to attempt to demodulate the eMBB until the demodulation is successful (or partial demodulation is successful) or the traversal is completed.

[0134] Specifically, the network device may use the optional difference values ​​included in the difference value set to sequentially demodulate the first service received in the first time period, and directly demodulate the first service.

[0135] Optionally, the difference value set is preset on the terminal device, or is configured for the terminal device by the network device.
