technical field

Background technique

Currently, wireless communication systems are widely deployed to provide various types of communication, such as voice services, data services, and the like. In some scenarios, such as drones and 4K HD live broadcast, there are requirements for uplink coverage and transmission rate. In uplink transmission, uplink power control is a technology that can achieve better coverage and transmission rate. For example, for terminal devices (or edge users) that are far away from the base station, the path loss is relatively large, and these edge users can use higher transmit power than terminal devices (central users) that are closer to the base station to compensate for the The path loss caused by distance transmission enables edge users to obtain better uplink coverage and transmission rate performance.

In order to improve uplink coverage and transmission rate, terminal equipment configured with high-capacity power amplifiers (or power amplifiers) can transmit signals with a higher than the maximum transmission power specified in the standard in a short period of time, so that the terminal equipment can transmit signals at high power instantaneously. When it is located at the edge of the cell, or when there is a large data packet for transmission, the transmission rate of the terminal device is increased, thereby improving the user experience. However, after a terminal device transmits with instantaneous high power for a period of time, the energy available for the terminal device for uplink transmission may be insufficient. When the network device continues to schedule the terminal device to send uplink signals, the terminal device may cause insufficient If the uplink signal transmission fails, the uplink coverage and uplink transmission rate will be affected.

Therefore, how to further improve uplink coverage and transmission rate still needs further research.

The network device can also be a server, a wearable device, or a vehicle-mounted device, etc. For example, the network device in the V2X technology may be a road side unit (road side unit, RSU). In the following, the base station is used as an example for the access network device to be described. The multiple network devices in the communication system may be base stations of the same type, or base stations of different types. The base station can communicate with the terminal equipment, and can also communicate with the terminal equipment through the relay station. A terminal device can communicate with multiple base stations in different access technologies. The core network equipment is used to implement functions such as mobility management, data processing, session management, policy and charging.

FIG. 2 shows another communication network architecture in the communication system 10 provided by the present application.

For example, the functions of the PDCP layer and above protocol layers are set in the CU, and the protocol layers below PDCP, such as the functions of the RLC layer and MAC layer, are set in the DU. It should be noted that the division of such protocol layers is only an example, and may also be divided in other protocol layers. The radio frequency device can be remote, not placed in the DU, or integrated in the DU, or partially remote and partially integrated in the DU, which is not limited in this application.

Compared with the architecture shown in Figure 2, the control plane (CP) and user plane (UP) of the CU can also be separated into different entities for implementation, namely the control plane CU entity (CU-CP entity) and the user plane CU entity (CU-UP entity). In this network architecture, the signaling generated by the CU can be sent to the UE through the DU, or the signaling generated by the UE can be sent to the CU through the DU. The DU can directly transmit the signaling to the UE or CU through protocol layer encapsulation without parsing the signaling. In this network architecture, a CU is classified as a network device on the RAN side. In addition, a CU may also be classified as a network device on the CN side, which is not limited in this application.

In order to improve the uplink coverage, a possible implementation method is that the terminal equipment configured with a high-capacity power amplifier (or power amplifier) can support sending signals at a maximum transmission power (for example, 23dBm) specified by the standard within a certain period of time, Therefore, through instantaneous high-power transmission, when the terminal device is located at the edge of the cell, or when there is a large data packet for transmission, the transmission rate of the terminal device is increased, thereby improving user experience. However, sending signals with high power for a long time may cause the total power of the terminal equipment to fail to meet regulatory requirements, or may cause radiation to the human body. Therefore, the average transmission power of the terminal device or the total energy used by the terminal device for signal transmission within a period of time needs to meet the condition that it does not exceed a certain threshold.

For example, as shown in Figure 4, within a time period of length T (hereinafter referred to as time period T), the terminal device can send uplink signals with a transmission power higher than the maximum specified in the standard (hereinafter referred to as instantaneous high power); but Within a time period of length L (hereinafter referred to as the time window), the average power of the terminal equipment does not exceed the maximum transmit power of the terminal equipment specified in the standard, where the time period T is within the time window, and the length of the time period T is less than or equal to the time window. In other words, in this scenario, the energy used by the terminal device for uplink transmission within the time window is constant, and the terminal device can transmit uplink signals with instantaneous high power within a certain period of time. When a terminal device transmits with instantaneous high power for a period of time, the energy available for uplink transmission of the terminal device may be insufficient (or energy overdraft), or even the energy available for uplink transmission may be zero. At this time, if the network device If the terminal device is still scheduled to send uplink signals, the uplink signal transmission failure of the terminal device may occur due to insufficient uplink transmission energy, affecting uplink coverage and uplink transmission rate.

Based on this, embodiments of the present application provide a communication method and a communication device, so as to improve uplink coverage and uplink transmission rate.

Referring to FIG. 5, an embodiment of a communication method provided by this application includes:

S501. The terminal device determines available uplink transmission energy within a first time period, where the first time period includes multiple time units.

The available uplink transmission energy is used for the transmission of uplink signals, and the available uplink transmission energy may also be referred to as available uplink transmission energy, or energy available for uplink transmission, or residual transmit energy (RTE) or other Name, this application does not limit the name, for the convenience of description, the name is the available uplink transmission energy as an example. The available uplink transmission energy in the first time period refers to the energy available for sending uplink signals in the first time period.

Wherein, the uplink signal may be at least one of the following: uplink data, uplink control signaling, or uplink reference signal. Specifically, the uplink data may be uplink service data; the uplink control signaling may be a scheduling request (scheduling request, SR), or a channel quality indicator (channel quality indicator, CQI), or an acknowledgment (acknowledgment, ACK), or a negative acknowledgment (negative acknowledgment); the uplink reference signal may be an uplink demodulation reference signal (demodulation reference signal, DMRS), a channel sounding signal (sounding reference signal, SRS), a preamble preamble, and the like.

It can be understood that the terminal device can transmit uplink signals with instantaneous high power within the time window, but the average transmit power of the terminal device in this time window does not exceed the maximum transmit power of the terminal device specified in the standard. Alternatively, it may be understood that the terminal device may transmit an uplink signal with instantaneous high power within the time window, but the energy used for uplink transmission of the terminal device within the time window does not exceed the second threshold. Optionally, the second threshold may be the product of the maximum transmit power of the terminal device and the length of the time window.

Optionally, there are many ways to express the position of the first time period, for example, it can be represented by the start time unit of the first time period and the end time unit of the first time period; or, it can be expressed by the first time period The starting time unit and the length of the first time period are represented. Correspondingly, the terminal device may determine the corresponding time domain resource of the first time period according to the start time unit of the first time period and the end time unit of the first time period; or, the terminal device may determine the corresponding time domain resource according to the start time unit of the first time period The position of the first time period is determined based on the initial time unit and the time length of the first time period.

Optionally, the start time unit of the first time period is the time unit when the terminal device sends the first indication information; or, the start time unit of the first time period is the time unit when the third indication information from the network device is received In the kth time unit after the time unit, the third indication information is used to instruct the terminal device to report the first indication information, and the k is a natural number; or, the starting time unit of the first time period is based on the time unit sent by the network device The configuration information is determined.

Optionally, the available uplink transmission energy is energy that can be used for uplink transmission from the start time unit to the end time unit; wherein the end time unit is a time unit corresponding to the end position of the time window; Alternatively, the termination time unit is determined according to configuration information sent by the network device. Optionally, the configuration information includes at least one of the following: a time length of the first time period, information about a start time unit of the first time period, or information about an end time of the first time period.

Further, the information of the start time unit of the first time period is an index of the start time unit of the first time period.

Further, the information of the end time unit of the first time period is an index of the end time unit of the first time period.

Further, the index of the start time unit and the index of the end time unit of the first time period may be indexes corresponding to the offset (or offset position) relative to the start position of the time window; or, the two The index may also be a position index relative to a certain time reference point, and the position of the time reference point may be the boundary of a certain radio frame (for example, the upper or lower boundary of the radio frame) and/or a certain radio subframe The boundaries of (for example, the upper boundary of the radio subframe and the lower boundary of the radio subframe), which are not limited in this application. In addition, the position of the time reference point may be preset by the protocol or indicated by the network device.

Optionally, the offset may be in units of time; in addition, the value of the offset may be a natural number, for example, the offset is 0, or 1, or 2, etc., which is not limited in the present application .

Optionally, configuration information may be carried in a radio resource control RRC message.

Optionally, the time unit may be a subframe, a time slot, a symbol, or a time unit of other granularity.

Instructions.

Optionally, the third indication information is carried in a radio resource control RRC message, or a PDCCH, or a medium access control control element MAC CE.

Optionally, the position of the time window may be preset by the protocol; or, the position of the time window is determined according to the position information of the time window from the network device.

Further, the time window may be a preset time unit, or a preset multiple time units continuous in the time domain. It can be understood that within a preset time unit or multiple preset time units that are continuous in the time domain, the uplink transmission energy of the terminal device does not exceed a certain threshold. Here, the time unit may be a radio frame, a subframe, a time slot, a symbol, or a time unit of other granularity.

For example, the time window may be a wireless frame, or the time window may be a preset multiple wireless frames that are continuous in the time domain; it can be understood that in a preset wireless frame or a preset time domain In multiple consecutive wireless frames, the uplink transmission energy of the terminal device does not exceed a certain threshold. In a possible implementation, the time window may be a radio frame M (or a radio frame with a serial number M), where M is a positive integer, and the value range of M may be 0 to 1023, for example, M is 10 or 100 or 500. In another possible implementation, the time window may be N radio frames that start from the radio frame M and are continuous in the time domain, where M and N are positive integers.

Further, there are many ways to express the location information of the time window. For example, the location information of the time window can be represented by cycle-related parameters, or the location information of the time window can be represented by timer-related parameters, as follows: a1 and a2 for explanation:

Mode a1: The position information of the time window is represented by period-related parameter information.

In this manner, the time window appears periodically, and the location information of the time window may include at least one of the following: a first period, a first starting position, a first offset, or a first duration.

For example, the time window includes a first period T, a first offset and a first duration. Correspondingly, the terminal device may determine the first starting position according to the system frame number (system frame number, SFN) and the first cycle T, and then determine the starting position of the time window according to the first starting position and the first offset, and determine the starting position of the time window according to the first period T. A duration determines the duration of the time window (or called the length of the time window).

The system frame number where the first starting position is located may satisfy one of the following formulas: SFN mod T=0; SFN mod T=offset; (SFN+offset)mod T=0.

Optionally, the value of the first offset offset is a natural number.

Further, when the value of the first offset offset is 0, the first offset value with a value of 0 may be carried in the position information of the time window; or, the first offset value may not be carried in the position information of the time window. In other words, if the position information of the time window does not include the first offset, the first offset may be 0 by default.

Mode a2: The position information of the time window is represented by parameters related to the timer.

In this manner, the location information of the time window includes: a first timer, and it can be understood that the terminal device can determine the time window according to the first timer.

For example, the terminal device starts (restarts) the first timer, and before the first timer expires, the terminal device determines that the corresponding time is the time of the time window; if the first timer expires, restart the first timer.

Optionally, the moment when the terminal device starts the first timer may be preset by the protocol or indicated by the network device.

Optionally, the location information of the time window may be carried in a radio resource control RRC message, or a PDCCH or a medium access control control element MAC CE.

Optionally, there are multiple ways for the terminal device to determine the available uplink transmission energy within the first time period, as described below in way b1:

Mode b1: The terminal device determines the energy available in the first time period according to the first energy value of the terminal device in the time window and the uplink transmission energy that the terminal device has used before the start time corresponding to the first time period of the time window. Send energy uplink.

In this manner, the terminal device determines the available uplink transmission energy within the first time period according to the first energy value of the terminal device within the time window and the uplink transmission energy already used by the terminal device.

Optionally, the first energy value may be a maximum value of energy configured by the terminal device for sending uplink signals.

Optionally, the first energy value may be preset, or determined according to the maximum transmit power of the terminal device and the length of the time window specified in the standard.

Further, the first energy value is equal to the product of the maximum transmit power of the terminal device specified in the standard and the length of the time window.

Further, the maximum transmit power of the terminal equipment specified in the standard may be 23dBm, 26dBm or 14dBm. It should be noted that, in this embodiment, if the terminal device determines that the value of the available uplink transmission energy in the first time period is not an integer, the value may be corrected by rounding up or rounding down. No restrictions.

S502. The terminal device sends first indication information, where the first indication information is used to indicate the available uplink transmission energy.

Correspondingly, the network device receives the first indication information sent by the terminal device.

Optionally, the first indication information is at least one of the following: available uplink transmission energy, index of available uplink transmission energy, average transmission power of uplink signals transmitted within the first time period, or average transmission power of uplink signals transmitted within the first time period Index of transmit power.

Optionally, the average transmission power of uplink signals sent during the first time period is the ratio of available uplink transmission energy to the number of all time units included in the first time period, or the average transmission power of uplink signals sent during the first time period The power is an average value of transmit power of uplink signals sent in all time units included in the first time period.

It should be noted that the above average value is based on the assumption that the terminal device sends signals in every time unit included in the first time period, so that the terminal device transmits the uplink signal according to the transmission power used by each time unit in the first time period , calculate the average transmit power of the uplink signal sent in the first time period.

It should be noted that the above-mentioned first time period is known to both the network device and the terminal device. It can be understood that the network device and the terminal device have the same understanding of the first time period, so the two can It is understood that the same available uplink transmission energy is determined according to the first indication information. In a possible design, the first time period may be determined by the terminal device based on the configuration information of the network device, or may be determined by the terminal device itself; The first time period is sent to the network device; here, the high-layer signaling can be an RRC message or MAC CE, and this application does not limit it.

For example, if the average transmission power of the uplink signal sent in the first time period is the ratio of the available uplink transmission energy to the number of all time units included in the first time period, the terminal device determines the available uplink signal in the first time period through S501 The transmission energy value is x, and the number of all time units included in the first time period is y, then the terminal device determines that the average transmission power of the uplink signal in the first time period is x/y.

For another example, if the average transmit power of uplink signals sent in the first time period is the average value of the transmit power of uplink signals sent in all time units included in the first time period, the terminal device determines that each time unit included in the first time period The transmit powers used to transmit uplink signals in time units are z1, z2, z3, z4, and z5, and the terminal device determines that the average transmit power of uplink signals in the first time period is (z1+z2+z3+z4+z5)/ 5.

Determine the index of the uplink transmission energy according to the available uplink transmission energy and the first correspondence, where the first correspondence is the correspondence between the available uplink transmission energy and the index of the uplink transmission energy; or,

Determine the index of the average transmission power according to the available uplink transmission energy and the second corresponding relationship, where the second corresponding relationship is the average transmission power of the uplink signal transmitted in the first time period and the average transmission power of the uplink signal transmitted in the first time period Correspondence between indices of power.

Optionally, there are multiple ways to represent the first correspondence, for example, it may be represented by a table.

In an example, the first correspondence is represented by a table, and the table may include a correspondence between an index of the uplink transmission energy and a range of the uplink transmission energy value (or called RTE). As shown in Table 1, it is an example of representing the first corresponding relationship through a table, and each index in the table corresponds to a range of uplink transmission energy values.

6262	36≤RTE＜3836≤RTE＜38
6363	RTE≥38RTE≥38

Optionally, the unit of the range of uplink transmission energy in this application may be joule, or kilojoule, or milliwatt×millisecond (mW×ms), or watt×millisecond (W×ms), or kilowatt×millisecond ( kW×ms), or Watt×second (W×s), which is not limited in this application.

It can be understood that the terminal device may determine the index of the available uplink transmission energy, that is, determine the first indication information, according to which range in Table 1 the available uplink transmission energy is within the first time period determined in S501.

For example, if the terminal device determines through S501 that the available uplink transmission energy value in the first time period is 35, according to Table 1, the index value of the uplink transmission energy value corresponding to 35 is 61, that is, the first indication information is 61.

In another example, the first correspondence is represented by two tables. Specifically, one table may include the index of the uplink transmission energy and the correspondence between the uplink transmission energy level, and the other table may include the uplink transmission energy level and the uplink transmission energy level. Correspondence between ranges of energy values (or called RTE). As shown in Table 2 and Table 3, it is an example of representing the first corresponding relationship through two tables, wherein each index in Table 2 corresponds to an uplink transmission energy level, and each uplink transmission energy level in Table 3 corresponds to There is a range of uplink sending energy value.

Table 3: Example of Correspondence Between Energy Levels and Energy Value Ranges

It can be understood that the terminal device may determine the energy level according to which range in Table 3 the available uplink transmission energy is within the first time period determined in S501; and determine the index of the available uplink transmission energy according to the determined energy level and Table 2, That is, the first indication information is determined.

For example, if the terminal device determines through S501 that the available uplink transmission energy value in the first time period is 33, according to Table 3, the energy level corresponding to 33 is RTE_60, and according to Table 2, the uplink transmission energy value corresponding to the energy level RTE_60 The index value of is 60, that is, the first indication information is 60.

It should be noted that, as the above Table 2 and Table 3 are only examples, the table size of the corresponding relationship between the index of the uplink transmission energy and the uplink transmission energy level, the relationship between the uplink transmission energy level and the uplink transmission energy value (or energy range) The corresponding relationship, the magnitude of the values in each table, and the units of the values in the tables are not limited in the present invention. However, in the same application scenario, the tables corresponding to Table 2 and Table 3 have the same size.

Optionally, there are multiple ways to represent the second correspondence, for example, it may be represented by a table.

In an example, the second corresponding relationship is represented by a table, and the table may include a corresponding relationship between an index of an average transmit power (average transmit power, ATP) and an average transmit power for sending uplink signals within the first time period. As shown in Table 4, it is an example of representing the second corresponding relationship through a table, and each index in the table corresponds to an average transmit power.
