Description

Uplink signal transmission method and device

Technical Field

The embodiments of the present invention relate to the field of communications, and more specifically, to a method and apparatus for transmitting an uplink signal.

Background Art

In current LTE communication systems, uplink transmission uses a single-carrier transmission method, primarily using a Discrete Fourier Transform-Spreading-Frequency Division Multiple Access (DFT-S-FDMA) waveform for uplink transmission. The main feature of the single-carrier transmission method is a relatively low peak-to-average power ratio (PAPR). This means that when a terminal transmits uplink signals to a network device, it can use a higher power level without worrying about the peak power exceeding the maximum transmission power supported by the terminal. This allows the single-carrier uplink transmission method to improve the transmission quality and coverage of uplink transmission by increasing the terminal's transmission power.

However, when using a single-carrier uplink transmission method to transmit uplink signals, the physical resources used to transmit uplink data must be continuous in the frequency domain to meet the characteristics of single-carrier transmission. In summary, the physical resource configuration method of single-carrier transmission means that when transmitting uplink signals, only one type of uplink signal can be transmitted on the entire allocated frequency domain physical resources within a time domain scheduling unit (such as a time slot), limiting the flexibility of uplink signal transmission.

Summary of the Invention

Embodiments of the present invention provide a method and apparatus for transmitting an uplink signal, so as to improve the flexibility of configuring physical resources for uplink control signals.

In the embodiment of the present invention, the uplink control signal is transmitted using a CP-OFDM waveform. By utilizing the multi-carrier transmission characteristics, the uplink control signal can be configured with physical resources that are continuous or discontinuous in the frequency domain. This avoids the need in the prior art to map the uplink control signal onto physical resources that are continuous in the frequency domain when uplink transmission of the uplink control signal is performed using a single carrier, thereby improving the flexibility of configuring physical resources for the uplink control signal.

DETAILED DESCRIPTION

The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings.

Network device 100 may be a device that communicates with terminal devices. Network device 100 may provide communication coverage for a specific geographic area and may communicate with terminal devices (e.g., UEs) within the coverage area.

Optionally, the wireless communication system 100 may include multiple network devices and each network device may include another number of terminals within its coverage area, which is not limited in this embodiment of the present invention.

Optionally, the wireless communication system 100 may further include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiment of the present application.

It should be understood that the technical solutions of the embodiments of the present invention can be applied to various communication systems, such as: 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, Advanced long term evolution (LTE-A) system, Universal Mobile Telecommunication System (UMTS), NR (New Radio Access Technology), 5G, etc.

The base station may be a base station (BTS) in GSM or CDMA, a base station (NodeB) in WCDMA, an evolved Node B (eNB or e-NodeB) in LTE, or a base station (gNB) in NR or 5G.

Specifically, the above-mentioned time domain scheduling unit can refer to an uplink scheduling period, or a time slot. In the case of a normal CP, the time domain scheduling unit can include 7 OFDM symbols, and in the case of an extended CP, the time domain scheduling unit can include 6 OFDM symbols.

The above-mentioned uplink control signal may include different types of uplink signals, for example, an ACK/NACK signal and a CSI feedback signal.

The above-mentioned physical resources may refer to resource elements (RE).

The uplink control signal is transmitted using a CP-OFDM waveform, which may refer to modulating the uplink control signal using the CP-OFDM waveform and mapping it to a corresponding physical resource.

Optionally, as an embodiment, in the time domain scheduling unit, the physical resources used to transmit the uplink control signal include at least one physical resource region, and different physical resource regions are used to transmit different types of uplink control signals.

Specifically, the uplink control signal may include multiple different types of uplink control signals.

It should be understood that the above-mentioned physical resource area may include multiple resource blocks, which may be continuous in the frequency domain; the above-mentioned physical resource area may also be a physical resource area on a resource block, that is, a resource block may include at least one physical resource area.

Optionally, each of the at least one physical resource region is composed of at least one frequency domain resource block in the frequency domain.

Optionally, the uplink control signal includes different types of uplink control signals, and the physical resources used to transmit the uplink control signal may refer to a resource block (PRB), and the resource block includes at least one physical resource area, and different physical resource areas are used to transmit different types of uplink control signals.

Specifically, the resource block may be used as a minimum scheduling unit for uplink signal transmission.

Each of the multiple physical resource regions may include multiple resource elements (REs) that are continuous in the frequency domain and multiple OFDM symbols.

Optionally, as an embodiment, the at least one physical resource area includes a first physical resource area, and the first orthogonal frequency division multiplexing OFDM symbol of the first physical resource area in the time domain is the starting OFDM symbol in the time domain scheduling unit.

For example, the first orthogonal frequency division multiplexing OFDM symbol in the time domain of the first physical resource region may refer to the first OFDM symbol of the PRB, that is, the starting OFDM symbol.

Optionally, the at least one physical resource region further includes a second physical resource region, and the second physical resource region is continuous with the first physical resource region in the time domain.

Optionally, the first physical resource area is used to transmit an ACK/NACK signal, and the second physical resource area is used to transmit a CSI feedback signal.

Optionally, the first physical resource area is also used to transmit a reference signal, that is, the first physical resource area can simultaneously transmit an ACK/NACK signal and a reference signal, and the reference signal is used to demodulate the ACK/NACK signal.

It should be understood that the ACK/NACK feedback mode corresponding to the above ACK/NACK signal may include an ACK/NACK merging mode and an ACK/NACK multiplexing mode, which is not specifically limited in the present invention.

It should be noted that when the first physical resource area transmits an uplink control signal, the second physical resource area can also be used to transmit uplink data; when the first physical resource area transmits an uplink control signal, the second physical resource area can also transmit an uplink control signal, wherein the uplink control signal transmitted in the first physical resource area may be of a different type from the uplink control signal transmitted in the second physical resource area.

Specifically, Figure 3 shows a schematic diagram of the physical resource configuration for transmitting uplink signals in an embodiment of the present invention. It should be understood that Figure 3 only illustrates the physical resource in which the first physical resource region includes 2 OFDM symbols as an example, and the embodiment of the present invention does not specifically limit the number of OFDM symbols included in the first physical resource region. It can be seen from Figure 3 that the physical resources (for example, a PRB) within the time domain scheduling unit include the first physical resource region, and the first OFDM symbol in the first physical resource region (that is, the first OFDM symbol in the time domain) can be the starting OFDM symbol in the time domain scheduling unit (that is, the first OFDM symbol in the time domain).

Optionally, as an embodiment, the at least one physical resource region includes a third physical resource region, and the last OFDM symbol of the third physical resource region in the time domain is the last OFDM symbol in the time domain scheduling unit.

It should be understood that FIG4 shows a schematic diagram of the physical resource configuration for transmitting uplink signals in another embodiment of the present invention. FIG4 only illustrates the physical resources of the third physical resource area containing 1 OFDM symbol as an example. The embodiment of the present invention does not specifically limit the number of OFDM symbols included in the third physical resource area. The physical resources corresponding to the OFDM symbols before the first OFDM symbol (i.e., the starting OFDM symbol) in the above-mentioned third physical resource area can be used for downlink transmission between the network device and the base station. That is to say, before the first OFDM symbol corresponding to the third physical resource area, switching between downlink transmission and uplink transmission is performed, and uplink transmission can be performed between the network device and the terminal starting from the first OFDM symbol corresponding to the third physical resource area. The above-mentioned physical resource configuration method can be called a short format for uplink control signal.

It should also be understood that the time-frequency resources before the first OFDM symbol in the above-mentioned third transmission area may include time-frequency resources for uplink transmission, that is, the first physical resource and/or the second physical resource may exist on the time-frequency resources before the first OFDM symbol in the third transmission area, but in the above-mentioned method for configuring time-frequency resources, the mode of the uplink control signal transmitted by the third physical resource no longer belongs to the short uplink signal control mode.

It should also be understood that the second physical resource area and the third physical resource area can be continuous in the time domain, that is, the next OFDM symbol of the last OFDM symbol in the second physical resource area can be used as the first OFDM symbol in the third physical resource area; there may also be overlapping physical resource areas between the second physical resource area and the third physical resource area, and the embodiments of the present invention do not specifically limit this.

It should be noted that there may be overlapping physical resource areas between the first physical resource area, the second physical resource area and the third physical resource area, and the first physical resource area, the second physical resource area and the third physical resource area may also be continuous in the time domain. The embodiment of the present invention does not limit the specific division method between the above-mentioned physical resource areas.

Optionally, the uplink control signal includes multiple ACK/NACK signals, and in the third physical resource area, the physical resources for transmitting the multiple ACK/NACK signals and the physical resources for transmitting the reference signal do not overlap, and the physical resources included in the resource group for transmitting the multiple ACK/NACK signals and the physical resources for transmitting the reference signal are arranged crosswise and continuously within the same OFDM symbol.

Specifically, the resource group includes a plurality of physical resources that are continuous in the frequency domain within one OFDM symbol, for example, a plurality of REs that are continuous in the frequency domain.

Optionally, the physical resources included in the resource group for transmitting the multiple ACK/NACK signals and the physical resources for transmitting the reference signal are arranged crosswise and continuously within the same OFDM symbol, which may mean that the resource group where the physical resources for transmitting the multiple ACK/NACK signals are located and the physical resources for transmitting the reference signal are arranged crosswise and continuously within the same OFDM symbol.

Optionally, in the third physical resource transmission area, the multiple ACK/NACK signals are extended and superimposed using different orthogonal sequences or pseudo-orthogonal sequences with the same length, and then repeatedly mapped to resource groups at different positions according to the number of transmissions of the multiple ACK/NACK signals, and the resource groups include physical resources for transmitting the multiple ACK/NACK signals.

Specifically, the resource groups at different positions mentioned above may mean that the positions corresponding to the multiple resource groups are different in the time domain scheduling unit.

Optionally, the resource groups at different locations may be continuous in the time domain and/or frequency domain.

For example, FIG5 shows a schematic diagram of the physical resource configuration for transmitting uplink signals according to another embodiment of the present invention. As can be seen from FIG5 , the positions of the physical resources for transmitting the reference signal and the positions of the resource groups for transmitting the ACK/NACK signal (see the first resource group and the second resource group in FIG5 ) are cross-arranged within the last OFDM symbol. The first ACK/NACK signal and the second ACK/NACK signal occupy consecutive physical resources within the first resource group, and at the same time, the first ACK/NACK signal and the second ACK/NACK signal occupy consecutive physical resources within the second resource group. That is, the first ACK/NACK signal and the second ACK/NACK signal are transmitted twice on the physical resources within the time domain scheduling unit. Among them, the first ACK/NACK signal and the second ACK/NACK signal can be extended and superimposed using different orthogonal sequences or pseudo-orthogonal sequences with the same length.

Optionally, as an embodiment, there is an overlapping physical resource area between the second physical resource area and the third physical resource area.

Specifically, the physical resources in the overlapping physical resource region may be configured for uplink signals transmitted in the second physical resource region, or may be configured for uplink signals transmitted in the third physical resource region.

It should be understood that the above-mentioned overlapping physical resource areas may refer to the overlap of a part of the physical resource area in the second physical resource area and a part of the physical resource area in the third physical resource area. The above-mentioned overlapping physical resource areas may also refer to the second physical resource area including the third physical resource area. The embodiment of the present invention does not limit the specific overlapping form of the second physical resource area and the third physical resource area.

Optionally, the uplink signal includes an uplink control signal and a reference signal, etc.

Optionally, as an embodiment, the uplink control signal includes a first type of uplink control signal and a second type of uplink control signal, and the method further includes: the network device configures, in the overlapping physical resource area, physical resources for the terminal to use for transmitting the first type of uplink signal; the network device configures, in the overlapping physical resource area, physical resources for the terminal to use for transmitting the second type of uplink signal, wherein the priority of the network device configuring the physical resources for the first type of uplink signal is higher than the priority of the network device configuring the physical resources for the second type of uplink signal.

Specifically, there is an overlapping physical resource area between the second physical resource area and the third physical resource area. The second physical resource area is used to transmit the second type of uplink control signal, and the third physical resource area is used to transmit the first type of uplink control signal. The network device can first configure the physical resources for transmitting the first type of uplink control signal for the terminal in the overlapping physical resource area, and configure the physical resources for transmitting the second type of uplink control signal for the terminal on physical resources other than the physical resources for transmitting the first type of uplink control signal.

Optionally, the first type of uplink control signal includes an ACK/NACK signal, and the second type of uplink control signal includes a CSI feedback signal.

For example, FIG6 shows a schematic diagram of a physical resource configuration for transmitting uplink signals according to another embodiment of the present invention. From the schematic diagram of the uplink transmission resource configuration shown in FIG6 , it can be seen that the first physical resource region includes the physical resources corresponding to the first OFDM symbol, the second physical resource region includes the physical resources corresponding to the second to fifth OFDM symbols, and the third physical resource region includes the physical resources corresponding to the fourth to seventh OFDM symbols. In other words, the overlapping physical resource region between the second and third physical resource regions includes the physical resources corresponding to the fourth OFDM symbol and the physical resources corresponding to the fifth OFDM symbol. The first physical resource region is used to transmit ACK/NACK signals, the second physical resource region is used to transmit CSI feedback signals, and the third physical resource region is used to transmit ACK/NACK signals.

It should be noted that any of the above-mentioned first physical resource area, second physical resource area and third physical resource area can also be used to transmit reference signals. The resource configuration diagram shown in Figure 5 only illustrates the example of transmitting reference signals in the first physical resource area.

Optionally, as an embodiment, when there is an overlapping physical resource area between the first physical resource area or the second physical resource area and the third physical resource area, that is, the network device configures the physical resources used for transmitting ACK/NACK signals and/or reference signals in the third physical resource area to the uplink control signals and/or reference signals transmitted in the first physical resource area or the second physical resource area. At this time, the uplink control signals and/or reference signals that occupy the physical resources in the third physical resource area for transmission can be punctured by the uplink control signals and/or reference signals that originally need to be transmitted in the third physical resource. This solves the problem of resource conflicts between uplink control signals and reference signals in different physical resource areas.

220. The network device receives the uplink control signal on the physical resource used for transmitting the uplink control signal, and the uplink control signal is transmitted using a cyclic prefix-orthogonal frequency division multiplexing (CP-OFDM) waveform.

Optionally, as an embodiment, the method further includes: the network device determines the physical resources used by the terminal to transmit the reference signal within the time domain scheduling unit, and the physical resources used to transmit the reference signal are configured in any one physical resource area of the at least one physical resource area.

Optionally, the third physical resource region is also used to transmit a reference signal, and the second physical resource region is also used to transmit a reference signal.

Specifically, the reference signal may be used to demodulate an ACK/NACK signal.

Optionally, the reference signal in the second physical resource region is not transmitted in the above-mentioned overlapping physical resource region.

It should be noted that the position of the physical resource corresponding to the physical resource for transmitting the reference signal can be fixed. That is, the physical resource for transmitting the reference signal in the second physical resource can be fixed, and the physical resource for transmitting the reference signal in the third physical resource can also be fixed. Since, in the overlapping physical resource area, the priority of configuring physical resources for the uplink signal transmitted in the second transmission physical resource area is lower than the priority of configuring physical resources for the uplink signal transmitted in the third transmission physical resource area, in order to avoid using the physical resources originally used for transmitting the reference signal to transmit the uplink control signal in the third physical resource area in the overlapping physical resource area, so that the network device cannot demodulate the ACK/NACK signal in the first transmission area according to the reference signal (in this case, the physical resource for transmitting the reference signal may not be configured in the first physical resource area), when configuring the physical resource for the reference signal transmitted in the second physical resource area, the physical resource for transmitting the reference signal may not be configured in the overlapping physical resource area.

For example, in the schematic diagram of the uplink transmission resource configuration shown in Figure 6, the reference signal is not transmitted in the physical resource area overlapping between the second physical resource area and the third physical resource area, that is, on the physical resources corresponding to the fourth OFDM symbol and the physical resources corresponding to the fifth OFDM symbol.

Optionally, the physical resources for transmitting the reference signal are discrete in the frequency domain or the time domain, or the physical resources for transmitting the reference signal are continuous in the frequency domain and/or the time domain.

Specifically, referring to the arrangement of physical resources for transmitting reference signals in the first physical resource region shown in FIG6 , within one OFDM symbol, the resource group where the physical resources for transmitting the reference signals are located is discrete in the frequency domain.

Referring to the arrangement of physical resources for transmitting reference signals in the second physical resource area shown in Figure 7, the resource group where the physical resources for transmitting reference signals are located includes multiple resource groups, and the resource group where the physical resources for transmitting reference signals are located is discrete in the frequency domain (which may mean that multiple resource groups correspond to different frequencies), wherein each resource group for transmitting reference signals occupies two consecutive OFDM symbols.

Referring to the arrangement of physical resources for transmitting reference signals in the second physical resource area shown in Figure 8, the resource group where the physical resources for transmitting the reference signal are located includes multiple resource groups, and each of the multiple resource groups occupies two different OFDM symbols. Within one of the OFDM symbols, the resource group where the physical resources for transmitting the reference signal are located is discrete in the frequency domain.

It should be noted that the embodiment of the present invention is only described by taking the example that the resource group used to transmit the reference signal includes two physical resources. The resource group used to transmit the reference signal can also include four physical resources. The embodiment of the present invention does not specifically limit the number of physical resources included in the resource group for transmitting the reference signal.

Optionally, as an embodiment, the uplink control signal includes multiple ACK/NACK signals, and in the first physical resource area, the physical resources for transmitting the multiple ACK/NACK signals and the physical resources for transmitting the reference signal do not overlap, and the physical resources included in the resource group for transmitting the multiple ACK/NACK signals and the physical resources for transmitting the reference signal are arranged crosswise and continuously within the same OFDM symbol.

Specifically, the resource group may include a group of continuous physical resources in the frequency domain, that is, one OFDM symbol may include multiple resource groups.

Optionally, the physical resources included in the resource group for transmitting the multiple ACK/NACK signals and the physical resources for transmitting the reference signal are arranged crosswise and continuously within the same OFDM symbol, which may mean that the resource group where the physical resources for transmitting the multiple ACK/NACK signals are located and the physical resources for transmitting the reference signal are arranged crosswise and continuously within the same OFDM symbol.

The resource group where at least part of the physical resources for transmitting multiple ACK/NACK signals are located may refer to all physical resources for transmitting multiple ACK/NACK signals being in one resource group; the resource group where at least part of the physical resources for transmitting multiple ACK/NACK signals are located may also refer to part of the physical resources for transmitting multiple ACK/NACK signals being in one resource group, and the remaining part of the physical resources for transmitting multiple ACK/NACK signals being in other resource groups.

Optionally, when the physical resources for transmitting multiple ACK/NACK signals are in multiple resource groups, the multiple resource groups are continuous or discrete in the frequency domain.

For example, Figure 9 shows a schematic diagram of physical resource configuration for transmitting uplink signals according to another embodiment of the present invention. In the resource configuration method shown in Figure 9, after the ACK/NACK signal is extended, transmission of the ACK/NACK signal requires eight physical resources (e.g., REs). However, since there are only four physical resources in the resource group between two physical resources used to transmit reference signals, two resource groups can be configured for the extended ACK/NACK signal, for a total of eight physical resources. The two resource groups are discontinuous in the frequency domain, but the physical resources within each resource group are continuous in the frequency domain.

It should be understood that the extended ACK/NACK signal transmitted by the physical resources in the above resource group

Optionally, the physical resources in the resource group where the physical resources of the multiple ACK/NACK signals are located are continuous in the frequency domain.

Optionally, as an embodiment, the multiple ACK/NACK signals are respectively extended using different orthogonal sequences or pseudo-orthogonal sequences with the same length, and then superimposed and mapped onto the resource group.

For example, after the first group of ACK/NACK signals is expanded by the first orthogonal sequence, and after the second group of ACK/NACK signals is expanded by the second orthogonal sequence, the first group of ACK/NACK signals and the second group of ACK/NACK signals can have the same length. For example, the first group of ACK/NACK signals and the second group of ACK/NACK signals can occupy 4 REs, and the first group of ACK/NACK signals and the second group of ACK/NACK signals can be mapped on the same resource group, which can include 4 REs.

Optionally, as an embodiment, the uplink control signal also includes a CSI feedback signal. In the second physical resource transmission area, the physical resources for transmitting the channel state information CSI feedback signal and the physical resources for transmitting the reference signal do not overlap, and the physical resources in the resource group for transmitting the reference signal are continuous in the time domain.

For example, the resource group for transmitting the reference signal includes 2 REs, a first RE and a second RE, wherein the first RE may be an RE occupying a first OFDM symbol, and the second RE may be an RE occupying a second OFDM symbol, the first OFDM symbol and the second OFDM symbol are continuous in the time domain, and the first RE and the second RE correspond to the same subcarrier.

Optionally, as an embodiment, in the first physical resource transmission area, the multiple ACK/NACK signals are extended and superimposed using different orthogonal or pseudo-orthogonal sequences with the same length, and then repeatedly mapped to resource groups at different positions according to the number of transmissions of the multiple ACK/NACK signals.

Specifically, the resource group includes physical resources used to transmit the multiple ACK/NACK signals.

For example, after the first group of ACK/NACK signals is expanded by the first orthogonal sequence, and after the second group of ACK/NACK signals is expanded by the second orthogonal sequence, the first group of ACK/NACK signals and the second group of ACK/NACK signals can have the same length. For example, the first group of ACK/NACK signals and the second group of ACK/NACK signals can occupy 4 REs. The first group of ACK/NACK signals and the second group of ACK/NACK signals can be respectively mapped to different resource groups, and each resource group can include 4 REs.

Optionally, as an embodiment, the multiple ACK/NACK signals correspond to downlink data blocks in different time-domain scheduling units, or the multiple ACK/NACK signals correspond to different codewords of the same downlink data block.

Taking the subframe as an example, the uplink signal transmission method is described in conjunction with Figure 10. Figure 9 shows a schematic diagram of an uplink signal transmission method according to another embodiment of the present invention. It can be seen from the uplink transmission method shown in Figure 10 that the uplink subframe carries the ACK/NACK signals of the downlink transmission subframe #0, subframe #1 and subframe #k, wherein the ACK/NACK signals of subframe #0 and subframe #1 are mapped to the physical resources in the first resource group of the uplink subframe. After the physical resources in the first resource group are occupied by the ACK/NACK signals, the ACK/NACK signal of subframe #k can be mapped to the physical resources in the second resource group corresponding to the uplink transmission subframe.

Optionally, as an embodiment, before the network device receives the uplink control signal on the physical resources used to transmit the uplink control signal, the method also includes: the network device sends indication information to the terminal, and the indication information is used to indicate the physical resources used to transmit the uplink control signal within the time domain scheduling unit.

Optionally, as an embodiment, the method further includes: the network device determines the number of transmissions required to transmit the uplink control signal and/or the extended sequence length of the uplink control signal; the network device indicates to the terminal the number of transmissions required to transmit the uplink control signal and/or the extended sequence length of the uplink control signal.

Specifically, the number of transmissions may refer to the number of repetitions required for the terminal to transmit the uplink control signal.

Optionally, the network device indicates to the terminal the number of transmissions required to transmit the uplink control signal and/or the extended sequence length of the uplink control signal, including: the network device sends downlink control information DCI to the terminal, and the DCI carries the number of transmissions required to transmit the uplink control signal and/or the extended sequence length of the uplink control signal.

Optionally, the network device indicates to the terminal the number of transmissions required to transmit the uplink control signal and/or the extended sequence length of the uplink control signal, including: the sequence length of the uplink control signal sent by the network device to the terminal; the number of physical resources sent by the network device to the terminal to transmit the uplink control signal.

Specifically, the network device indicates to the terminal the sequence length for sending the uplink control signal and the number of physical resources for the terminal to transmit the uplink control signal, so that the terminal determines the number of transmissions (which may refer to the number of repetitions) for transmitting the uplink control signal based on the sequence length for sending the uplink control signal and the number of physical resources for the terminal to transmit the uplink control signal.

For example, the terminal determines that the sequence length for sending an uplink control signal is 4, and the network device configures 8 REs for the terminal to transmit the uplink control signal. The terminal may determine that the number of transmissions for transmitting the uplink control signal is 2.

Optionally, the network device indicates to the terminal the number of transmissions required to transmit the uplink control signal and/or the extended sequence length of the uplink control signal, including: the network device sends high-layer signaling to the terminal, and the high-layer signaling carries the number of transmissions required to transmit the first type of uplink signal and/or the extended sequence length of the first type of uplink signal.
