BSC

Backscatter communication means that a backscatter communication device performs signal modulation by using a radio frequency signal in another device or an environment to transmit information. The backscatter communication device may be a tag or a Passive-IoT in conventional RFID. The backscatter communication device controls a reflection coefficient I of a circuit by adjusting internal impedance of the backscatter communication device, to change an amplitude, a frequency, a phase, and the like of an incident signal, thereby implementing signal modulation. A reflection coefficient of a signal may be represented as:

$Γ = \frac{Z_{1} - Z_{0}}{Z_{1} + Z_{0}} = ❘ Γ ❘ e^{j θ_{T}}$

Z₀is antenna characteristic impedance, and Z₁is load impedance. It is assumed that the incident signal is S_in(t). In this case, an output signal is S_out(t)=S_in(t)|Γ|e^jθ^T. Therefore, corresponding amplitude modulation, frequency modulation, or phase modulation can be implemented through proper control of the reflection coefficient.

Transmitting/receiving procedure

As shown in FIG. 1b, a current protocol of an Ultra High Frequency (UHF) RFID is designed in an inventory mode, and a reader is required to send a query instruction (Query), and a tag responds with a reply (Reply), that is, generates a 16-bit random number to a reader. Then, after the reader sends the sequence to the Tag by using an ACK instruction, the Tag sends related data to the reader.

Two types of application scenarios of backscatter

(1) Cellular backscatter scenario-no assistance from a terminal, as shown in FIG. 1c.

(2) Cellular backscatter scenario assisted by a terminal, as shown in FIG. 1d and FIG. 1e. In FIG. 1d, a terminal receives feedback information sent by a Tag. In FIG. 1e, the terminal sends a Carrier Wave (CW) and a signaling command or control to the Tag. A signaling type includes at least one of the following: select, inventory, and access. A network receives feedback information of the Tag.

For example, a system architecture of backscatter includes multiple types shown in FIG. 1f.

A resource allocation method provided in embodiments of this application is described in detail below with reference to the accompanying drawings by using some embodiments and application scenarios thereof.

As shown in FIG. 2, an embodiment of this application provides a resource allocation method that includes the following steps:

Step 201: A network side device configures a resource used for transmitting a BSC channel or signal.

Step 202: The network side device schedules transmission of the BSC channel or signal.

In an embodiment, an entity that transmits the BSC channel or signal may include at least one of the network side device, a Tag, and a terminal.

It should be noted that transmission in the embodiments of this application may include sending or receiving.

In this embodiment of this application, the network side device configures the resource used for transmitting the BSC channel or signal, and the network side device schedules the transmission of the BSC channel or signal, to allocate a BSC resource, and improve communication reliability of a BSC service.

It should be noted that the method in this embodiment of this application may be applied to a BSC scenario between a Tag and a gNB shown in FIG. 1f, or a BSC communication scenario between a Tag and a gNB in which a terminal participates.

The BSC channel or signal includes one or more of the following:

(1) A carrier wave channel or signal. For example, the carrier wave CW channel or signal includes an excitation signal, which may be referred to as CW for short. In an embodiment, the carrier wave CW channel or signal may be information sent by the network side device to a tag, or may be information sent by a terminal to a tag. In some embodiments, the carrier wave CW channel or signal may further include a data channel that is referred to as a shared channel.

(2) A control channel or signal, for example, a select signal, a query signal, a query repeat signal, a reply signal, a read signal, a write signal, or a random request signal, which may be referred to as a command for short. In an embodiment, the control channel or signal may be information sent by the network side device to a tag, or may be information sent by a terminal to a tag.

(3) A feedback channel or signal, for example, Tag identification information (such as a 16-bit random number that temporarily represents a Tag identity in a query process), electronic product code information, and Tag status information, which may be referred to as feedback for short. In an embodiment, the feedback channel or signal may be information sent by a tag to a terminal through backscatter, or may be information sent by a tag to the network side device through backscatter.

In a possible implementation, that a network side device configures a resource used for transmitting a BSC channel or signal includes:

- the network side device configures a target frequency band used for transmitting the BSC channel or signal.

The target frequency band may also be referred to as a target band.

In this embodiment of this application, the network side device deploys BSC on a band of a specific mobile communication system. For example, an NR system allocates a new band to a BSC service, which may be shown in FIG. 3a.

In a possible implementation, that a network side device configures a resource used for transmitting a BSC channel or signal includes:

- the network side device configures a center frequency used for transmitting the BSC channel or signal.

In this embodiment of this application, a network specifies a center frequency of BSC. For example, the network may indicate the center frequency of the BSC in an Absolute Radio Frequency Channel Number (ARFCN) manner. In addition, in one case, a specific frequency domain resource size may be not configured, but may be determined by using a specific hardware radio frequency-related implementation.

In a possible implementation, that a network side device configures a resource used for transmitting a BSC channel or signal includes:

- the network side device configures a target carrier or a target serving cell used for transmitting the BSC channel or signal.

In this embodiment of this application, the network side device configures a specific carrier or a serving cell for BSC, which may be shown in FIG. 3b. For example, the network side device configures a dedicated secondary cell for BSC to transmit the BSC channel or signal.

In some embodiments, the target carrier or the target serving cell is only used for BSC transmission.

It should be noted that BSC transmission mentioned above and below refers to transmission of the BSC channel or signal.

Further, that the network side device schedules transmission of the BSC channel or signal includes:

- the network side device schedules the BSC channel or signal to be transmitted on the target carrier or the target serving cell by using a target control signaling. The target control signaling is a signaling sent by the network side device on a carrier or a serving cell that is not used for BSC transmission, or the target control signaling is a signaling sent by the network side device on the target carrier or the target serving cell.

The target control signaling may be Radio Resource Control (RRC) signaling, a Media Access Control-Control Element (MAC CE), or downlink control information DCI.

In an optional implementation, the network side device triggers data transmission on a serving cell specific to BSC in a manner of crossing carrier scheduling.

In an optional implementation, the network side device schedules BSC transmission on a specific carrier or serving cell by sending RRC, a MAC CE, or DCI in a serving cell that is not used for BSC. For example, the network side device sends DCI in a cell 1 to schedule BSC transmission in a cell dedicated to BSC. In other words, the network side device schedules BSC transmission by cross carrier scheduling.

In a possible implementation, that a network side device configures a resource used for transmitting a BSC channel or signal includes:

- the network side device configures a target Bandwidth Part (BWP) used for transmitting the BSC channel or signal, where the target BWP includes a target uplink BWP and/or a target downlink BWP.

It should be noted that the target part bandwidth used for transmitting the BSC channel or signal is referred to as a BSC BWP below, the target uplink BWP is a BSC Uplink (UL) BWP, and the target downlink BWP is a BSC Downlink (DL) BWP.

In some embodiments, the target BWP is used for BSC transmission only.

In this embodiment of this application, the network side device configures a specific BWP for BSC, and the BSC BWP includes at least one of the BSC DL BWP and the BSC UL BWP, which may be shown in FIG. 3c.

Further, a configuration of the target BWP does not include one or more of the following:

- (1) a Physical Downlink Control Channel (PDCCH)-related configuration;
- (2) a Physical Downlink Shared Channel (PDSCH)-related configuration;
- (3) a Physical Uplink Shared Channel (PUSCH)-related configuration;
- (4) a Physical Uplink Control Channel (PUCCH)-related configuration; and
- (5) a reference signal-related configuration.

Further, the configuration of the target BWP includes one or more of the following:

- (1) an identifier ID of the target BWP;
- (2) a bandwidth of the target BWP;
- (3) a Sub-Carrier Spacing (SCS) of the target BWP; and
- (4) a related configuration of the BSC channel or signal.

In this embodiment of this application, a PDCCH, a PDSCH, and the like may not be configured on the BSC BWP, and there is only a channel/signal configuration related to transmission of a BSC service. In other words, in content configured on a BWP in a related technology, except for content related to BSC transmission, an original configuration of an NR channel/signal may be omitted and not configured.

For example, the configuration of the target BWP may not include at least one of the following configurations:

- pdsch-configCommon (including a Cell specific parameter), pdcch-config (including a UE specific parameter), pdsch-config (including a UE specific parameter), SPS-config (used for a single BWP, where an NW may release SPS-config at any time), radioLinkMonitoringConfig (used for detect cellular and beam radio link faults), RACH-configCommon pucch-configCommon (including a Cell specific parameter), pusch-configCommon (including a Cell specific parameter), pucch-config (including a UE specific parameter), pusch-config (including a UE specific parameter), CG-config, beamFailureRecoveryConfig, and SRS-config.

Further, the method further includes:

- (1) activating or applying the target BWP, and starting a first timer (a first timer); and
- (2) after the expiry of the first timer, the network side device switches to a preconfigured BWP.

In this embodiment of this application, in a case of switching to a BSC BWP, a BWP-fallback timer (that is, the first timer) is started, and the network side device switches back to the preconfigured BWP after the expiry of the timer. In an embodiment, the terminal can have only one activated BWP in one serving cell at a same moment. Therefore, if the terminal applies the BSC BWP to work, that is, a currently activated BWP is the BSC BWP, because parameters such as a PDCCH are not configured on the BSC BWP, the terminal cannot receive, on the BSC BWP, signaling sent by the network side device to return to a BWP for transmitting the PDCCH and a PDSCH. Therefore, in a case that the first timer expires, the terminal may return to the preconfigured BWP by using a configuration of the first timer, where the preconfigured BWP is the BWP for transmitting the PDCCH and the PDSCH.

In some embodiments, the network side device activates or applies both the target BWP and another BWP that is a non-target BWP.

In this embodiment of this application, the BSC BWP and a non-BSC BWP (for example, a BWP used for transmitting a physical channel) may be activated or applied at the same time. Therefore, in this embodiment, an objective of simultaneously transmitting a BSC service and an existing mobile communication service (for example, an NR communication service) can be implemented. It should be noted that in an embodiment, a BSC service transmitted on the BSC BWP is received by an additional receiver in a receiving device (for example, a terminal). The additional receiver refers to another receiver that is different from a receiver that receives a mobile communication channel or signal such as a PDCCH or a PDSCH in a related technology, and may be understood as a receiver that is used to receive the BSC service.

For example, the BSC service is transmitted on the BSC BWP by obtaining network scheduling signaling on the non-BSC BWP.

In a possible implementation, that a network side device configures a resource used for transmitting a BSC channel or signal includes:

- the network side device configures the BSC channel or signal to be transmitted on a first BWP, where the first BWP is further used for first transmission, and the first transmission is used to transmit a channel or signal other than the BSC channel or signal.

In some embodiments, the first transmission may be used for transmitting a channel or a signal including at least one of the following: a PDSCH, a Synchronization Signal and PBCH Block (SSB), a Channel State Information-Reference Signal (CSI-RS), a Sounding Reference Signal (SRS), a Physical Random Access Channel (PRACH), a Physical Uplink Control Channel (PUCCH), and a Physical Uplink Shared Channel (PUSCH). In an example, the channel or signal, other than the BSC channel or signal, used for transmission is an NR channel or signal.

In this embodiment of this application, BSC transmission and NR transmission may be configured on a same BWP (that is, the first BWP), that is, BSC transmission and NR transmission are supported to be performed on one BWP. It should be noted that NR transmission is merely used as an example of the first transmission for description herein. In some embodiments, it may be understood that the first transmission may be LTE transmission or other transmission used for transmitting a channel or signal other than the BSC channel or signal. A type of the first transmission is not specifically limited in this embodiment of this application. For all subsequent descriptions of an example related to the first transmission, NR transmission is used as an example for description, and details are not described again.

Further, the first BWP is a BWP with a specific BWP index. In other words, the network configures BSC to be transmitted on a BWP with a specified BWP ID.

Further, that the network side device configures the BSC channel or signal to be transmitted on the first BWP includes:

- the network side device configures the BSC channel or signal to be transmitted on a target frequency domain resource of the first BWP. In other words, the network is configured to perform BSC transmission on a specific frequency domain resource of the first BWP.

In an embodiment, the specific frequency domain resource may include a specific Resource Block set (RB set) (which may be multiple consecutive RBs) and a specific RB. For example, it is agreed that BSC is transmitted on an RB with an RB ID-0 on the first BWP, that is, the network side device allocates RBO on the first BWP for BSC transmission.

In a possible implementation, that the network side device schedules transmission of the BSC channel or signal includes at least one of the following:

(1) The network side device schedules the transmission of the BSC channel or signal by sending Downlink Control Information (DCI) signaling.

In this embodiment of this application, the network side device sends DCI to UE, and dynamically schedules transmission of the BSC by using the DCI. For example, if a carrier indicated by a Carrier Indicator Field (CIF) in the DCI is a carrier for BSC transmission, an information field subsequent to the CIF in the DCI is redefined to indicate information about a parameter (for example, a BSC resource allocation parameter) related to transmission of the BSC service.

(2) The network side device schedules the transmission of the BSC channel or signal by configuring semi-persistent transmission.

In an embodiment, a network side configures at least one semi-persistent transmission configuration, and indicates, by using signaling such as DCI, to activate one or more semi-static configurations, so that the terminal is scheduled to transmit or receive the BSC channel or signal in a transmission opportunity of the activated one or more semi-static configurations.

With reference to any one or more of the foregoing embodiments, in a possible implementation, the related configuration parameter of the transmission of the BSC channel or signal includes one or more of the following:

- (1) power information (for example, Transmit Power Control (TPC) information);
- (2) a frequency domain resource, for example, frequency domain resource parameters include a frequency domain resource size, a frequency domain resource start location, and the like;
- (3) a bandwidth;
- (4) a time domain resource, for example, time domain resource parameters include a time domain resource length, a time domain resource start location, and the like;
- (5) a resource cycle, for example, if the resource cycle is 10 ms, it indicates that there is a resource for one BSC transmission every 10 ms;
- (6) duration occupied by a resource in each resource cycle;
- (7) a waveform, which refers to a waveform used for BSC transmission, such as an On-Off Keying (OOK) waveform;
- (8) a sending timeline for the BSC channel or signal, which refers to a time gap requirement that sending of the BSC channel or signal needs to be met; where for example, sending of the BSC channel or signal requires a period of preparation time, and in this case, after receiving a signaling for scheduling the sending of the BSC channel or signal, the BSC channel or signal needs to be sent after a time gap greater than or equal to the preparation time;
- (9) a receiving timeline for the BSC channel or signal, which refers to a time gap requirement that receiving of the BSC channel or signal needs to be met; where for example, receiving of the BSC channel or signal requires a period of decoding time, and in this case, after receiving the BSC channel or signal, a HARQ corresponding to the BSC channel or signal can be sent only after a time gap greater than or equal to the decoding time; and
- (10) Hybrid Automatic Repeat request-ACK (HARQ-ACK) resource information corresponding to the BSC channel or signal.

In a possible implementation, the transmission of the BSC channel or signal and the first transmission satisfy at least one of Time Division Multiplexing (TDM) and Frequency Division Multiplexing (FDM). The first transmission is used to transmit a channel or signal other than a BSC channel or signal, which may be shown in FIG. 3d.

In a possible implementation, in a case that the transmission of the BSC channel or signal and the first transmission satisfy TDM or satisfy TDM and FDM, a time gap between the transmission of the BSC channel or signal and the first transmission is greater than or equal to a first threshold.

In other words, in a case that the transmission of the BSC channel or signal and the first transmission satisfy TDM or satisfy TDM and FDM, the time gap between the BSC transmission and the first transmission is greater than or equal to a specific value.

In a case that the transmission of the BSC channel or signal and the first transmission satisfy FDM or satisfy TDM and FDM, a frequency domain interval between the transmission of the BSC channel or signal and the first transmission is greater than or equal to a second threshold.

In other words, in a case that the transmission of the BSC channel or signal and the first transmission satisfy FDM or satisfy TDM and FDM, the frequency domain interval between the BSC transmission and the first transmission is greater than or equal to a specific value.

In a possible implementation, the method further includes:

- interruption time exists in a process of switching between the transmission of the BSC channel or signal and the first transmission, and the network side device does not perform data transmission within the interruption time.

For example, there is specific interruption time in a process of switching between the BSC transmission and NR transmission. In the interruption time, it may be assumed that the terminal or the network side device does not send or receive data. One reason for the foregoing switching process is that the terminal does not support simultaneous execution of the BSC transmission and the first transmission.

In a possible implementation, before the network side device configures the resource used for transmitting the BSC channel or signal, the method further includes:

- the network side device receives first capability information sent by the terminal.

The first capability information includes one or more of the following:

A person of ordinary skill in the art may be aware that, in combination with the examples described in the embodiments disclosed in this specification, units and algorithm steps may be implemented by using electronic hardware or a combination of computer software and electronic hardware. Whether the functions are performed by hardware or software depends on particular applications and design constraints of the technical solutions. A person skilled in the art may use different methods to implement the described functions for each particular application, but it should not be considered that the implementation goes beyond the scope of the present disclosure.

It can be clearly understood by a person skilled in the art that, for the purpose of convenient and brief description, for a detailed operating process of the foregoing system, apparatus, and unit, refer to a corresponding process in the foregoing method embodiments. Details are not described herein again.

In the embodiments provided in this application, it should be understood that the disclosed apparatus and method may be implemented in other manners. For example, the described apparatus embodiment is merely an example. For example, the unit division is merely logical function division and may be other division in actual implementation. For example, multiple units or components may be combined or integrated into another system, or some features may be ignored or not performed. In addition, the displayed or discussed mutual couplings or direct couplings or communication connections may be implemented through some interfaces. The indirect couplings or communication connections between the apparatuses or units may be implemented in electronic, mechanical, or other forms.

The units described as separate parts may or may not be physically separate, and parts displayed as units may or may not be physical units, may be located in one position, or may be distributed on multiple network units. Some or all of the units may be selected based on actual requirements to achieve the objectives of the solutions in the embodiments.

In addition, functional units in the embodiments of the present disclosure may be integrated into one processing unit, or each of the units may exist alone physically, or two or more units are integrated into one unit.

When the functions are implemented in a form of a software functional unit and sold or used as an independent product, the functions may be stored in a computer readable storage medium. Based on such an understanding, the technical solutions of the present disclosure essentially, or the part contributing to the related art, or some of the technical solutions may be implemented in a form of a software product. The computer software product is stored in a storage medium, and includes several instructions for instructing a computer device (which may be a personal computer, a server, a network device, or the like) to perform all or some of the steps of the methods described in the embodiments of the present disclosure. The foregoing storage medium includes: any medium that can store program code, such as a USB flash drive, a removable hard disk, a ROM, a RAM, a magnetic disk, or an optical disc.

A person of ordinary skill in the art may understand that all or some of the processes of the methods in the embodiments may be implemented by a computer program controlling related hardware. The program may be stored in a computer readable storage medium. When the program runs, the processes of the methods in the embodiments are performed. The foregoing storage medium may include: a magnetic disk, an optical disc, a ROM, a RAM, or the like.

It should be noted that, in this specification, the term “include”, “comprise”, or any other variant thereof is intended to cover a non-exclusive inclusion, so that a process, a method, an article, or an apparatus that includes a list of elements not only includes those elements but also includes other elements which are not expressly listed, or further includes elements inherent to this process, method, article, or apparatus. In absence of more constraints, an element preceded by “includes a . . . ” does not preclude the existence of other identical elements in the process, method, article, or apparatus that includes the element. In addition, it should be noted that the scope of the methods and apparatuses in the embodiments of this application is not limited to performing functions in the order shown or discussed, but may also include performing the functions in a basically simultaneous manner or in opposite order based on the functions involved.
