Description

Power distribution method and terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a power allocation method and a terminal.

Background

In a fifth Generation (5th Generation, 5G) mobile communication system, or referred to as New Radio (NR) system, a physical layer introduces a New Radio Network Temporary Identity (RNTI) for indicating a New Modulation and Coding Scheme (MCS) table (table), and the New MCS table is generally used for higher priority services, such as high-reliability Ultra-Low Latency communication (URLLC) services.

After introducing the new RNTI and the new MCS table, generally, it is considered that the priority of a service corresponding to the new RNTI and the new MCS table is higher, and in terms of Cell power allocation, the terminal preferentially ensures the power allocation of a Primary Cell (Primary Cell, Pcell) or a Primary and Secondary Cell (PScell), and then considers the power allocation of the Secondary Cell (Scell). Thus, if the service priority conflicts with the cell power allocation priority, if the RNTI of the non-indicated MCS table is configured on the Pcell and the RNTI indicating the new MCS table is configured on the Scell, the RNTI configuration of the non-indicated MCS table on the Pcell is preferentially ensured according to the cell power allocation priority, so that the power allocation of the service with higher priority cannot be ensured. Or when the priority of cell power allocation is the same, if both the RNTI indicating the MCS table and the RNTI indicating the new MCS table are configured on the Scell, the terminal cannot determine the final power allocation.

Referring to fig. 1, fig. 1 is a block diagram of a wireless communication system to which an embodiment of the present invention is applicable. The wireless communication system includes a terminal 11 and a network device 12. The terminal 11 may also be referred to as a terminal Device or a User Equipment (UE), where the terminal 11 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device, and the specific type of the terminal 11 is not limited in the embodiment of the present invention. The network device 12 may be a Base Station or a core network, wherein the Base Station may be a 5G or later-version Base Station (e.g., a gNB, a 5G NR NB, etc.), or a Base Station in other communication systems (e.g., an eNB, a WLAN access point, or other access points, etc.), wherein the Base Station may be referred to as a node B, an evolved node B, an access point, a Base Transceiver Station (BTS), a radio Base Station, a radio Transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, or some other suitable terminology in the field, as long as the same technical effect is achieved, the Base Station is not limited to a specific technical vocabulary, it should be noted that, in the embodiment of the present invention, only the Base Station in the NR system is taken as an example, but does not limit the specific type of base station.

The base stations may communicate with the terminals 11 under the control of a base station controller, which may be part of the core network or some of the base stations in various examples. Some base stations may communicate control information or user data with the core network through a backhaul. In some examples, some of the base stations may communicate with each other, directly or indirectly, over backhaul links, which may be wired or wireless communication links. A wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on the multiple carriers simultaneously. For example, each communication link may be a multi-carrier signal modulated according to various radio technologies. Each modulated signal may be transmitted on a different carrier and may carry control information (e.g., reference signals, control channels, etc.), overhead information, data, and so on.

The base station may communicate wirelessly with the terminal 11 via one or more access point antennas. Each base station may provide communication coverage for a respective coverage area. The coverage area of an access point may be divided into sectors that form only a portion of the coverage area. A wireless communication system may include different types of base stations (e.g., macro, micro, or pico base stations). The base stations may also utilize different radio technologies, such as cellular or WLAN radio access technologies. The base stations may be associated with the same or different access networks or operator deployments. The coverage areas of different base stations (including coverage areas of base stations of the same or different types, coverage areas utilizing the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.

The communication links in a wireless communication system may comprise an Uplink for carrying Uplink (UL) transmissions (e.g., from terminal 11 to network device 12) or a Downlink for carrying Downlink (DL) transmissions (e.g., from network device 12 to terminal 11). The UL transmission may also be referred to as reverse link transmission, while the DL transmission may also be referred to as forward link transmission. Downlink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both. Similarly, uplink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both.

An embodiment of the present invention provides a power allocation method, which is applied to a terminal, and as shown in fig. 2, the method includes the following steps:

step 21: if the total transmission power in a transmission period is greater than a preset threshold, performing power distribution according to preset priority information; wherein the pre-set priority information is related to the type of transmission and the channel and/or signal of the transmission.

For uplink multi-carrier transmission or carrier aggregation scenarios, the total transmit power of the terminal during one transmit period may exceed a preset threshold, i.e., given a maximum transmit power, where power allocation conflicts may arise, in order to guarantee the transmission of higher priority traffic and higher priority channels and/or signals, embodiments of the present invention allocate power according to preset priority information, the preset priority information is related to the transmission type of the service and the transmission channel and/or signal, the service with higher priority and the channel and/or signal with higher priority are in the high priority position of the preset priority information, this ensures that higher priority traffic and higher priority channels and/or signals are preferentially allocated so as not to affect the transmission of such traffic, channels and/or signals.

Wherein the presetting of the priority information comprises the following steps: first priority information relating to the type of transmission, and second priority information relating to the channel and/or signal being transmitted. It is worth pointing out that the elements in the first priority information and the second priority information may be interspersed, but their respective priority order is guaranteed to be unchanged; that is, the order of the elements adjacent to each other in the first priority information in the preset priority information may not be adjacent, but the relative priority relationship is not changed. Assuming that the first priority information includes element a, element B, element C, and element D with priorities from high to low, and the second priority information includes element 1, element 2, element 3, element 4, and element 5 with priorities from high to low, the element a, element B, element C, and element D may be located at any positions of element 1, element 2, element 3, element 4, and element 5 in the preset priority information, but the priority order of element a > element B > element C > element D is still maintained, for example, the order of elements in the preset priority information may be: element a, element 1, element 2, element B, element 3, element C, element D, element 4, and element 5. The above description about the order of the elements in the first priority information and the second priority information is only used as an exemplary illustration, other elements satisfying the first priority information and the second priority information may be arranged alternately, but the order of their respective priority order invariance rules also belongs to an implementable example of the embodiment of the present invention, and this embodiment is not listed one by one.

Further, in a preferred embodiment, the transmission type having the lowest power allocation priority in the first priority information has a higher power allocation priority than the channel and/or signal having the lowest power allocation priority in the second priority information. That is, the element having the lowest priority in the first priority information is higher in priority than the element having the lowest priority in the second priority information. Still taking the above example as an example, assuming that there are element a, element B, element C, and element D with priorities from high to low in the first priority information and element 1, element 2, element 3, element 4, and element 5 with priorities from high to low in the second priority information, then element a, element B, element C, and element D may be located at any position before element 5 in the preset priority information, but the priority order of element a > element B > element C > element D is still maintained, for example, the order of elements in the preset priority information may be: element a, element 1, element 2, element B, element 3, element C, element 4, element D, and element 5.

Wherein the elements in the first priority information are related to transmission types, the first priority information may include at least two of the following elements:

A. a first transmission type dynamically scheduled by a first Radio Network Temporary Identifier (RNTI); the information corresponding to the first transmission type is dynamically scheduled by a first RNTI, wherein the first RNTI (a new RNTI, which may be called MCS-C-RNTI) is used to indicate a first MCS table (or a new MCS table, which may be called a new 64QAM MCS table) including a high-order modulated MCS, which may be used for higher priority traffic, such as URLLC traffic.

B. A second transmission type of a scheduling-exempt (configured grant) indicated by the first modulation and coding strategy MCS table; the information corresponding to the second transmission type is configured without scheduling indicated by the first MCS table.

C. A third transmission type not dynamically scheduled using the first RNTI, e.g., dynamically scheduled using a second RNTI; the information corresponding to the third transmission type is not dynamically scheduled using the first RNTI, e.g., the information may be dynamically scheduled using the second RNTI, or other types of dynamic scheduling. The second RNTI is an RNTI (or an existing RNTI) other than the first RNTI, such as a Cell Radio Network Temporary Identity (C-RNTI) and the like.

D. A fourth transmission type that is not scheduled using the exempt indicated by the first MCS table, such as scheduled exempt indicated using the second MCS table; the information corresponding to the fourth transmission type is not configured using the scheduling free configuration indicated by the first MCS table, e.g., the information may be configured using the scheduling free configuration indicated by the second MCS table, or other scheduling free type.

It is noted that the priority of the first transmission type and the second transmission type is higher than the higher priority of the third transmission type and the fourth transmission type. Here, the first and/or second transmission type has a higher priority than the third and/or fourth transmission type. In addition, the priority of the first transmission type may be higher than the priority of the second transmission type, or vice versa. For example, if a and C/D are included in the first priority information, the priority order may be: a > C/D. If B and C/D are included in the first priority information, the priority order may be: b > C/D. If A, B and C are included in the first priority information, the priority order may be: a > B > C or B > A > C. If A, C and D are included in the first priority information, the priority order may be: a > C > D. If A, B and D are included in the first priority information, the priority order may be: a > B > D or B > A > D. If B, C and D are included in the first priority information, the priority order may be: b > C > D. If A, B, C and D are included in the first priority information, the priority order may be: a > B > C > D or B > A > C > D. It is worth pointing out that the above sequence is only an exemplary illustration, and the embodiments are not exhaustive.

Wherein the elements in the second priority information are related to the transmitted channel and/or signal, the second priority information may include priority from high to low:

1. a Physical Random Access Channel (PRACH) transmitted on the primary cell Pcell, that is, the PRACH on the Pcell is transmitted;

2. a first Physical Uplink Control Channel (PUCCH) carrying Hybrid Automatic Repeat Request acknowledgement (Hybrid Automatic Repeat Request ACK, HRAQ-ACK) and/or Scheduling Request (Scheduling Request, SR), that is, PUCCH carrying HARQ-ACK feedback or SR is transmitted; or a Physical Uplink Shared Channel (PUSCH) carrying HARQ-ACK feedback is sent;

3. a second PUCCH carrying Channel State Information (CSI) or a second PUSCH carrying CSI, that is, a PUCCH carrying CSI or a PUSCH carrying CSI is transmitted;

4. a third PUSCH not carrying HARQ-ACK or CSI, namely PUSCH transmission not carrying HARQ-ACK feedback or CSI;

5. sounding Reference Signal (SRS), wherein the aperiodic SRS has a higher priority than the semi-persistent SRS.

It is worth pointing out that the elements in the first priority information and the second priority information may be interspersed, but the respective priority orders are guaranteed to be unchanged, that is, A, B, C and D in the first priority information may be located at any position of 1, 2, 3, 4 and 5 in the second priority information, but the relative priorities of the elements in the first priority information need to be guaranteed to be unchanged. Further, the transmission type having the lowest power allocation priority in the first priority information has a higher power allocation priority than the channel and/or signal having the lowest power allocation priority in the second priority information. That is A, B, C and D are both higher priority than 5. The priority order of each element in the preset priority information from high to low may be: a and/or B can be located at any position before 5, and C and/or D can be located at any position after A and/or B and before 5, and the combination of priority orders satisfying the above relations can be understood by those skilled in the art, so that the above relations are not listed.

Further, the transmission type in the first priority information may be indicated by at least one of:

indicating the first mode, first Downlink Control Information (DCI) of Cyclic Redundancy Check (CRC) is scrambled by a first RNTI. For example, the first transmission type (dynamic scheduling by the first RNTI) is indicated by the first DCI of the first RNTI-scrambled CRC.

Indicating a second mode, configuring a first scheduling-free resource of a first MCS table; for example, the second transmission type (scheduling exempt indicated by the first MCS table) is indicated by a first scheduling exempt resource configuring the first MCS table.

Indicating a third mode, scrambling second DCI of CRC through a second RNTI; for example, the third transmission type (dynamic scheduling without using the first RNTI) is indicated by the second DCI of the second RNTI-scrambled CRC.

Indicating a fourth mode, configuring a second scheduling-free resource of a second MCS table; for example, a fourth transmission type (without scheduling exempt indicated by the first MCS table) is indicated by a second scheduling exempt resource configuring the second MCS table.

Indication mode five, target DCI format (format); wherein, the target DCI format includes but is not limited to: a dedicated DCI format and an extended DCI format. Taking the special DCI as an example, the special DCI refers to a DCI format specially used for indicating a transmission type that is newly defined, that is, a priority is determined through the new DCI format, and if the new DCI format is used for indicating a first transmission type, a second transmission type, and/or a high-priority service, high-priority power allocation is scheduled by using the new DCI format. For example, the exempt scheduling indicated by the first MCS table is activated with a new DCI format. On the other hand, taking the extended DCI format as an example, the extended DCI format refers to an extended DCI format, that is, a function of enhancing an existing DCI format to indicate a first transmission type, a second transmission type, and/or a high priority service, and then high priority power allocation is performed for scheduling by using the extended DCI format. For example, the extended DCI format is used to activate the exempt scheduling indicated by the first MCS table.

Indicating a sixth mode, a target Search Space (SS); wherein the target search space includes but is not limited to: common Search Space (CSS) and/or dedicated Search Space (USS). Wherein different transmission types may be indicated by different search spaces, e.g. a first transmission type, a second transmission type and/or high priority traffic is indicated by the CSS, e.g. the exempt scheduling indicated by the first MCS table is activated with DCI within the CSS. The third transmission type, the fourth transmission type, and/or the low priority traffic are indicated by the USS, e.g., a exempt scheduling indicated by the unused first MCS table is activated with DCI within the USS. Or vice versa, i.e. the first transmission type, the second transmission type and/or the high priority traffic is indicated by the USS and the third transmission type, the fourth transmission type and/or the low priority traffic is indicated by the CSS.

Indication mode seven, scheduling symbol number; different transmission types are indicated by different numbers of symbols allocated in the scheduling information. For example, a threshold is defined, the number of symbols in the dynamic scheduling is lower than the threshold, and the number of symbols configured in the configuration information without scheduling is lower than the threshold, and the number of symbols is used for indicating the second transmission type and/or the high priority service. If the number of dynamically scheduled symbols is higher than the threshold, the dynamically scheduled symbols are used for indicating the third transmission type and/or the low priority service, and the number of symbols configured in the scheduling-free configuration information is higher than the threshold, the dynamically scheduled symbols are used for indicating the fourth transmission type and/or the first priority service. Or otherwise, when the number of dynamically scheduled symbols is higher than the threshold, the dynamically scheduled symbols are used for indicating the first transmission type and/or the high priority service, and the number of symbols configured in the scheduling-free configuration information is higher than the threshold, and the dynamically scheduled symbols are used for indicating the second transmission type and/or the high priority service. And if the number of the dynamically scheduled symbols is lower than the threshold, the dynamically scheduled symbols are used for indicating a third transmission type and/or a low priority service, and the number of the symbols configured in the scheduling-free configuration information is lower than the threshold, and the dynamically scheduled symbols are used for indicating a fourth transmission type and/or a first priority service.

Indicating a mode eight and scheduling a period; different transmission types are indicated by configuring different lengths of the scheduling period. For example, a threshold is defined below which the configured period length is below for indicating the second transmission type and/or high priority traffic. And if the configured cycle length is higher than the threshold, the configured cycle length is used for indicating the fourth transmission type and/or the first priority service. Or vice versa, the configured cycle length is higher than the threshold, and is used for indicating the second transmission type and/or the high-priority service. And if the configured cycle length is lower than the threshold, indicating the fourth transmission type and/or the first priority service.

And indication mode nine, resource allocation type, and different transmission types are indicated through different resource allocation types. For example, the first transmission type, the second transmission type and/or the high priority service is indicated by type1, if the configured resource is indicated by type1, it represents that the configured resource is the first transmission type, the second transmission type and/or the high priority service, the third transmission type, the fourth transmission type and/or the low priority service is indicated by type2, and if the configured resource is indicated by type2, it represents that the configured resource is the third transmission type, the fourth transmission type and/or the low priority service. Or vice versa, i.e. the first transmission type, the second transmission type and/or the high priority traffic is indicated by type2 and the third transmission type, the fourth transmission type and/or the low priority traffic is indicated by type 1.

It should be noted that the indication modes may be combined, and the number and types of combinations thereof are not limited, for example, the indication mode one and the indication mode five may be combined, the indication mode seven and the indication mode eight may be combined, and the combined indication of other combination modes also belongs to a feasibility example of the embodiment of the present invention, and is not listed here.

In the power allocation method of the embodiment of the invention, when the total transmission power of the terminal in a transmission period is greater than the preset threshold, the power allocation is carried out according to the preset priority information, and as the priority information is related to the transmission type and the transmission channel and/or signal, the service priority and the cell power allocation priority are comprehensively considered, so that the problem of power allocation conflict can be avoided, and the power allocation is more optimized and reasonable.

The foregoing embodiments describe the power allocation method in different scenarios, and the following describes a terminal corresponding to the power allocation method with reference to the accompanying drawings.

As shown in fig. 3, the terminal 300 according to the embodiment of the present invention can implement details of a power allocation method according to preset priority information if the total transmission power in one transmission period is greater than a preset threshold in the foregoing embodiment, and achieve the same effect; wherein, the preset priority information is related to the transmission type and the transmission channel and/or signal, and the terminal 300 specifically includes the following functional modules:

the processing module 310 is configured to, when the total transmission power in a transmission period is greater than a preset threshold, perform power allocation according to preset priority information; wherein the pre-set priority information is related to the type of transmission and the channel and/or signal of the transmission.

Wherein the presetting of the priority information comprises the following steps: first priority information relating to the type of transmission, and second priority information relating to the channel and/or signal being transmitted.

Wherein, the transmission type with the lowest power distribution priority in the first priority information has a higher power distribution priority than the channel and/or signal with the lowest power distribution priority in the second priority information.

Wherein the first priority comprises a priority relationship of at least two of:

a first transmission type dynamically scheduled by a first Radio Network Temporary Identifier (RNTI);

a second scheduling-free transmission type indicated by the first modulation and coding strategy, MCS, table;

a third transmission type not dynamically scheduled using the first RNTI;

the priority of the first transmission type and the second transmission type is higher than the higher priority of the third transmission type and the fourth transmission type.

Wherein the second priority information comprises the following priority levels from high to low:

configuring a second scheduling-free resource of a second MCS table;

a resource allocation type.

Wherein, the target DCI format comprises: a dedicated downlink control information, DCI, format and/or an extended DCI format.

Wherein the target search space comprises: a common search space CSS and/or a dedicated search space USS.

It is worth pointing out that, when the total transmission power of the terminal in the embodiment of the present invention is greater than the preset threshold in one transmission period, the terminal performs power allocation according to the preset priority information, and since the priority information is related to the transmission type and the transmission channel and/or signal, the service priority and the cell power allocation priority are comprehensively considered, which can avoid the problem of power allocation conflict, so that the power allocation is more optimized and reasonable.

It should be noted that the division of each module of the above terminal is only a division of a logical function, and the actual implementation may be wholly or partially integrated into one physical entity, or may be physically separated. And these modules can be realized in the form of software called by processing element; or may be implemented entirely in hardware; and part of the modules can be realized in the form of calling software by the processing element, and part of the modules can be realized in the form of hardware. For example, the determining module may be a processing element separately set up, or may be implemented by being integrated in a chip of the apparatus, or may be stored in a memory of the apparatus in the form of program code, and the function of the determining module is called and executed by a processing element of the apparatus. Other modules are implemented similarly. In addition, all or part of the modules can be integrated together or can be independently realized. The processing element described herein may be an integrated circuit having signal processing capabilities. In implementation, each step of the above method or each module above may be implemented by an integrated logic circuit of hardware in a processor element or an instruction in the form of software.

For example, the above modules may be one or more integrated circuits configured to implement the above methods, such as: one or more Application Specific Integrated Circuits (ASICs), or one or more microprocessors (DSPs), or one or more Field Programmable Gate Arrays (FPGAs), among others. For another example, when one of the above modules is implemented in the form of a Processing element scheduler code, the Processing element may be a general-purpose processor, such as a Central Processing Unit (CPU) or other processor capable of calling program code. For another example, these modules may be integrated together and implemented in the form of a system-on-a-chip (SOC).

To better achieve the above object, further, fig. 4 is a schematic diagram of a hardware structure of a terminal implementing various embodiments of the present invention, where the terminal 40 includes, but is not limited to: radio frequency unit 41, network module 42, audio output unit 43, input unit 44, sensor 45, display unit 46, user input unit 47, interface unit 48, memory 49, processor 410, and power supply 411. Those skilled in the art will appreciate that the terminal configuration shown in fig. 4 is not intended to be limiting, and that the terminal may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components. In the embodiment of the present invention, the terminal includes, but is not limited to, a mobile phone, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted terminal, a wearable device, a pedometer, and the like.
