Description

Technical Field

[0001] This disclosure relates to, but is not limited to, the field of wireless communication technology, and particularly to a resource processing method and apparatus, communication equipment, and storage medium. Background Technology

[0002] In the Long Term Evolution (LTE) 4th Generation (4G) communication system, two major technologies were proposed to support Internet of Things (IoT) services: Machine-Type Communication (MTC) and Narrow Band-Internet of Things (NB-IoT). These two technologies are primarily aimed at scenarios with low data rates and high latency, such as meter reading and environmental monitoring.

[0003] NB-IoT currently only supports speeds of a few hundred kilobytes per second, while MTC currently only supports speeds of a few megabytes per second.

[0004] Meanwhile, with the continuous development of IoT services, such as video surveillance, smart homes, wearable devices, and industrial sensing and monitoring, these services typically require speeds of tens to 100 Mbps, while also having relatively high latency requirements. Therefore, LTE's MTC and NB-IoT technologies are difficult to meet these requirements.

[0005] Given this situation, in related technologies, there are specific applications for fifth-generation mobile communication (5G). th In the 5G New Radio (NR) era, a new type of User Equipment (UE) is provided to cover the aforementioned communication requirements. This new type of terminal is called a Reduced Cap (RedCap) UE or RedCap terminal. Summary of the Invention

[0006] This disclosure provides a resource processing method and apparatus, a communication device, and a storage medium resource processing method.

[0007] A first aspect of this disclosure provides a resource processing method, wherein the method is executed by a base station, the method comprising:

[0008] The response allocates resources to the first type of terminal, based on the bandwidth supported by the first type of terminal.

[0009] A second aspect of this disclosure provides a resource processing method, wherein the method is executed by a first type of terminal, the method comprising:

[0010] The system receives a DCI including resource allocation information, wherein the resource allocation information indicates frequency domain resources allocated to the first type of terminal, and the frequency domain resources are determined based on the bandwidth supported by the first type of terminal.

[0011] A third aspect of this disclosure provides a resource processing apparatus, wherein the apparatus includes:

[0012] The allocation module is configured to allocate resources to the first type of terminal in response to the first type of terminal, and to allocate resources according to the bandwidth supported by the first type of terminal.

[0013] A fourth aspect of this disclosure provides a resource processing apparatus, wherein the apparatus includes:

[0014] The receiving module is configured to receive DCI including resource allocation information, wherein the resource allocation information indicates frequency domain resources allocated to the first type of terminal, and wherein the frequency domain resources are determined based on the bandwidth supported by the first type of terminal.

[0015] A fifth aspect of this disclosure provides a communication device, including a processor, a transceiver, a memory, and an executable program stored in the memory and executable by the processor, wherein the processor executes the resource processing method as provided in the first or second aspect above when running the executable program.

[0016] A sixth aspect of this disclosure provides a computer storage medium storing an executable program; the executable program, when executed by a processor, can implement the resource processing method provided in the first or second aspect described above.

[0017] The technical solution provided in this disclosure allocates resources to the first type of terminal in this way. On the one hand, it enables the first type of terminal to transmit data on the allocated resources without frequently switching the center frequency point of its operation. On the other hand, when allocating resources according to the bandwidth supported by the first type of terminal, the resource allocation information indicating the resource allocation result requires fewer bits, thereby reducing the bit overhead of resource allocation.

[0033] Please refer to Figure 1 This illustration shows a schematic diagram of the structure of a wireless communication system provided in an embodiment of this disclosure. Figure 1 As shown, the wireless communication system is a communication system based on cellular mobile communication technology. The wireless communication system may include: several UEs 11, several access devices 12, and several core network elements 13 connected to the access devices 12.

[0034] UE 11 can be a device that provides voice and / or data connectivity to a user. UE 11 can communicate with one or more core networks via a Radio Access Network (RAN). UE 11 can be an IoT UE, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT UE. For example, it can be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment (UE). Alternatively, UE 11 can also be a device in an unmanned aerial vehicle (UAV). Alternatively, UE 11 can also be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless communication device connected to an external vehicle computer. Alternatively, UE 11 can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0035] Access device 12 can be a network-side device in a wireless communication system. This wireless communication system can be a 4G system (also known as Long Term Evolution, LTE); or it can be a 5G system (also known as a New Radio, NR, or 5G NR system). Alternatively, it can be the next generation after 5G. In this case, the access network in the 5G system can be called NG-RAN (New Generation-Radio Access Network). Alternatively, it can be an MTC system.

[0036] The access device 12 can be an evolved NB (eNB) used in a 4G system. Alternatively, the access device 12 can also be a gNB (gNB) using a centralized-distributed architecture in a 5G system. When the access device 12 adopts a centralized-distributed architecture, it typically includes a central unit (CU) and at least two distributed units (DUs). The central unit is equipped with a protocol stack of the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, and the Media Access Control (MAC) layer; the distributed units are equipped with a physical (PHY) layer protocol stack. This disclosure does not limit the specific implementation of the access device 12.

[0037] Access device 12 and UE 11 can establish a wireless connection via a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth-generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth-generation mobile communication network technology (5G) standard, such as a new air interface; or, the wireless air interface can also be a wireless air interface based on a next-generation mobile communication network technology standard based on 5G.

[0038] like Figure 2 As shown, this disclosure provides a resource processing method, which is executed by a base station, and the method includes:

[0039] S1110: The response allocates resources to the first type of terminal, based on the bandwidth supported by the first type of terminal.

[0040] The resource processing method may include the base station allocating resources to the first type of terminal.

[0041] The base station includes, but is not limited to, evolved NBs (eNBs) and / or next-generation NBs (gNBs).

[0042] For example, the first type of terminal may be a RedCap terminal or an enhanced eRedCap terminal.

[0043] For example, the first type of terminal can support a transmit / receive bandwidth of 20MHz or even 5MHz.

[0044] Of course, the above is just an example of the first type of terminal, and the actual implementation is not limited to the above example.

[0045] The terminal capable of communicating with the terminal may further include a second type of terminal, which differs from the first type of terminal. For example, the second type of terminal supports a bandwidth greater than that supported by the first type of terminal. Exemplarily, the second type of terminal includes, but is not limited to, an enhanced mobile broadband (eMBB) terminal.

[0046] When allocating resources to the first type of terminal, the resources are allocated according to the bandwidth supported by the first type of terminal. This resource allocation includes: frequency domain resource allocation according to the bandwidth supported by the first type of terminal.

[0047] For example, resource allocation based on the bandwidth supported by the first type of terminal may include: determining the bandwidth of the activated BWP or the initial BWP of the first type of terminal based on the bandwidth supported by the first type of terminal. As another example, determining the number of resource blocks (RBs) allocated to the first type of terminal at one time based on the bandwidth supported by the first type of terminal. These RBs can also be referred to as physical resource blocks (PRBs).

[0048] In this disclosure, there are several ways to allocate resources for the first type of terminal, which may include:

[0049] Type 0: A non-contiguous allocation method for frequency domain resources;

[0050] Type 1, a continuous allocation method for frequency domain resources.

[0051] In this embodiment of the disclosure, S1110 may include: allocating resources to the first type of terminal in response to type 1, and allocating resources according to the bandwidth supported by the first type of terminal.

[0052] Using this method to allocate resources to the first type of terminal allows the first type of terminal to transmit data on the allocated resources without frequently switching its center frequency. On the other hand, when allocating resources according to the bandwidth supported by the first type of terminal, the number of bits required for resource allocation information is small, thereby reducing the bit overhead of resource allocation.

[0053] like Figure 3 As shown, this disclosure provides a resource processing method, which is executed by a base station, and the method includes:

[0054] S1210: The response allocates resources to the first type of terminal, and determines the number of RBs that the bandwidth portion BWP configured for the first type of terminal can contain based on the first bandwidth supported by the first type of terminal; wherein, the first bandwidth is determined based on the maximum frequency range that the first type of terminal can receive or transmit.

[0055] The first bandwidth capability of the first type of terminal includes, but is not limited to, the transmit / receive bandwidth of the first type of terminal. This transmit / receive bandwidth may be the maximum operating bandwidth of the radio frequency structure of the first type of terminal. For example, the transmit / receive bandwidth of the first type of terminal may be the maximum bandwidth supported by the antennas included in the first type of terminal.

[0056] If the working BWP (or activated BWP or initial BWP) of the first type of terminal is determined based on the first bandwidth capability of the first type of terminal, then once the BWP is determined, there is no need for resource allocation information to separately indicate the number of RBs contained in the allocated BWP, thus reducing bit overhead.

[0057] like Figure 4 As shown, this disclosure provides a resource processing method, which is executed by a base station, and the method includes:

[0058] S1310: The response allocates resources to the first type of terminal, and allocates the number of RBs for data transmission to the first type of terminal according to the second bandwidth supported by the first type of terminal; wherein, the second bandwidth is determined according to the maximum number of processing RBs supported by the first type of terminal for data transmission.

[0059] This resource processing method can be implemented alone or in combination with the technical solutions provided in any of the foregoing embodiments.

[0060] The second bandwidth supported by the first type of terminal includes, but is not limited to, the baseband processing bandwidth of the first type of terminal.

[0061] For example, the processing bandwidth of the baseband processor of the first type of terminal may be the baseband processing bandwidth.

[0062] If the number of RBs is allocated according to the second bandwidth supported by the first terminal, the subsequent resource allocation information does not need to additionally indicate the number of RBs allocated to the first type of terminal each time, or reduce the number of bits required to indicate the number of RBs allocated each time, thereby reducing bit overhead.

[0063] If the number of RBs is scheduled at one time according to the second bandwidth supported by the first type of terminal, it will facilitate efficient data processing of the first type of terminal.

[0064] For example, the number of RBs allocated for data transmission by the first type of terminal is less than or equal to the second bandwidth supported by the first type of terminal.

[0065] In this embodiment of the disclosure, if the number of RBs allocated for data transmission to the first type of terminal is less than or equal to the second bandwidth supported by the first type of terminal, the phenomenon of excessive bandwidth allocated to the first type of terminal at one time, resulting in large encoding and decoding latency of the first type of terminal, can be reduced.

[0066] like Figure 5 As shown, this disclosure provides a resource processing method, which is executed by a base station, and the method includes:

[0067] S1410: The response allocates resources to the first type of terminal, based on the bandwidth supported by the first type of terminal.

[0068] S1420: The resource indicator (RIV) is used to jointly indicate the starting RB number S and the number of consecutively distributed RBs allocated to the first type of terminal.

[0069] In this embodiment of the disclosure, Type 1 is used to allocate resources for the first type of terminal. Therefore, the RBs allocated for data transmission on the active BWP of the first type of terminal will be continuously distributed.

[0070] After allocating the resources to the first type of terminal, the RIV will be used to jointly indicate the starting RB number S and the number of consecutively allocated RBs to the first type of terminal.

[0071] For example, the RIV can be a resource index that corresponds to both the number S of a starting RB and the number (or length) L of RBs. The correspondence between the RIV and the RB number S and the number L of RBs can be specified by a protocol or pre-written into the first type of terminal and base station.

[0072] Thus, when the base station uses the RIV to indicate the resources allocated to the first type of terminal, it can determine the RIV to be sent based on the correspondence and the starting numbers S and L of the RB currently allocated to the first type of terminal; and then send the RIV to the first type of terminal.

[0073] It is worth noting that during the process of the base station allocating resources to the first type of terminal, the position of the starting RB and the number of RBs can be flexibly determined by making full use of each RB based on the remaining status of the active BWP of the first type of terminal.

[0074] In this embodiment of the disclosure, all RIVs are determined based on BWP-size and Lmax. BWP-size is the size of the BWP containing the RB allocated to the first type of terminal. Lmax is determined based on the second bandwidth supported by the first type of terminal. Furthermore, BWP-size is determined based on the first bandwidth supported by the first type of terminal.

[0075] Specifically, when S is less than or equal to the difference between BWP-size and Lmax, the value of RIV is: S*Lmax+L;

[0076] When S is greater than the difference between BWP-size and Lmax, the value of RIV is: (BWP-size-Lmax)*Lmax+{(Lmax-1)+(Lmax-2)+…+(Lmax-(S-(BWP-size-Lmax)))};

[0077] Wherein, Lmax is the maximum number of RBs in the first type of terminal;

[0078] L is the actual number of the first type of terminal RB;

[0079] The BWP-size is the size of the BWP containing the RB allocated to the first type of terminal.

[0080] If the RB number on the BWP is from 0 to BWP-size-1, then the value of S can range from 0 to BWP-size-2. In this embodiment of the present disclosure, if L RBs are allocated to the first type of terminal, then the value of S ranges from 0 to BWP-size-2-L.

[0081] Lmax represents the maximum number of Restricted Blocks (RBs) supported by the first type of terminal. For example, Lmax can be determined based on the second bandwidth supported by the first type of terminal. For instance, Lmax could be equal to the number of RBs corresponding to the second bandwidth supported by the first type of terminal. Assuming the second bandwidth supported by the first type of terminal is 5MHz, then Lmax is equal to the floor of the quotient between 5MHz and the bandwidth value of a single RB.

[0082] The value of L can be any positive integer.

[0083] BWP-size can also be considered as the number of RBs contained in the active BWP of the first type of terminal.

[0084] In this embodiment of the disclosure, both the base station and the first type of terminal know the conversion relationship between RIV and S and L. After the base station completes the resource allocation, it can determine the RIV according to the conversion relationship. After receiving the RIV, the first type of terminal determines the S and L represented by the currently received RIV according to the conversion relationship, thereby knowing the RB allocated by the base station for the first type of terminal.

[0085] As can be seen in this embodiment, the RIV is determined based on Lmax, and has the characteristics of simple RIV numbering and low bit overhead.

[0086] In some embodiments, the BWP-size may be determined based on a first bandwidth supported by the first type of terminal. For example, the BWP-size may be equal to the number of RBs corresponding to the first bandwidth supported by the first type of terminal. Assuming that the first bandwidth supported by the first type of terminal is 20MHz, then the BWP-size may be equal to 20MHz, or the BWP-size may be the floor function of the quotient between 20MHz and the bandwidth value of a single RB.

[0087] If S is greater than the difference between BWP-size and Lmax, it means that the number of available RBs remaining in the BWP is less than the number of Lmax. However, these remaining RBs can still be allocated. In this case, the value of RIV can be related to (Lmax-1), (Lmax-2)...(Lmax-(S-(BWP-size-Lmax)) etc., based on each actual allocation. Therefore, the RIV at this time is (BWP-size-Lmax)*Lmax+{(Lmax-1)+(Lmax-2)+...+(Lmax-(S-(BWP-size-Lmax)))}.

[0088] In some embodiments, the method further includes:

[0089] S1430: Send downlink control information (DCI) containing the RIV.

[0090] The RIV is carried in the DCI and sent to the first type of terminal. The DCI of the first type of terminal has the characteristic of good dynamism. Thus, after the resource allocation of the first type of terminal is completed, the DCI can be used flexibly and quickly to send the RIV to the first type of terminal.

[0091] DCI belongs to physical layer signaling. In other embodiments, the RIV can also be carried in non-physical layer signaling, such as MAC CE or RRC signaling. Of course, this is just an example, and the actual implementation is not limited to this example.

[0092] In some embodiments, the first type of terminal includes: an enhanced capability reduction eRedCap terminal.

[0093] In some embodiments, the first type of terminal includes, but is not limited to, eRedCap terminals, and may also be other types of terminals, such as, but not limited to, MTC terminals.

[0094] like Figure 6 As shown, this disclosure provides a resource processing method, which is executed by a first type of terminal. The method includes:

[0095] S2110: Receive DCI including resource allocation information, wherein the resource allocation information indicates frequency domain resources allocated to the first type of terminal, wherein the frequency domain resources are determined based on the bandwidth supported by the first type of terminal.

[0096] This resource processing method can be executed by the first type of terminal itself.

[0097] The first type of terminal will receive a DCI containing resource allocation information. The frequency domain resources indicated by this resource allocation information are allocated according to the bandwidth supported by the first type of terminal. If this resource allocation method is adopted, the number of bits consumed by the resource allocation information can be reduced, thereby reducing the bit overhead of the DCI.

[0098] It is worth noting that the frequency domain resource allocation method in this embodiment may include type 0 and type 1. In this embodiment, the frequency domain resource allocation method for the first type of terminal may adopt type 1.

[0099] In some embodiments, receiving the DCI including resource allocation information includes:

[0100] Receive a DCI containing an RIV, wherein the RIV jointly indicates the starting RB number S and the number L of consecutively distributed RBs assigned by the base station to the first type of terminal.

[0101] In this embodiment of the disclosure, the DCI carries an RIV, which simultaneously indicates the starting RB number S and the number L of consecutively allocated RBs. Thus, after receiving the RIV, the first type of terminal determines S and L based on the RIV, and then identifies the corresponding RB on its own working BWP as the RB scheduled by the base station for data transmission.

[0102] In some embodiments, the number of RBs included in the BWP of the first type of terminal is determined based on the first bandwidth supported by the first type of terminal, wherein the first bandwidth is determined based on the maximum frequency range that the first type of terminal can receive or transmit.

[0103] And / or,

[0104] The number of RBs allocated to the first type of terminal is less than or equal to the second bandwidth supported by the first type of terminal, wherein the second bandwidth is determined based on the maximum number of processing RBs supported by the first type of terminal for data transmission.

[0105] In this embodiment of the disclosure, all RIVs are determined based on BWP-size and Lmax. BWP-size is the size of the BWP containing the RB allocated to the first type of terminal. Lmax is determined based on the second bandwidth supported by the first type of terminal. Furthermore, BWP-size is determined based on the first bandwidth supported by the first type of terminal.

[0106] In some embodiments, when S is less than or equal to the difference between BWP-size and Lmax, the value of RIV is: S*Lmax+L;

[0107] When S is less than or equal to the difference between BWP-size and Lmax, the value of RIV is: (BWP-size-Lmax)*Lmax+{(Lmax-1)+(Lmax-2)+…+(Lmax-(S-(BWP-size-Lmax)))};

[0108] Wherein, Lmax is the maximum number of RBs in the first type of terminal;

[0109] L is the actual number of the first type of terminal RB;

[0110] The BWP-size is the size of the BWP containing the RB allocated to the first type of terminal.

[0111] If the RB number on the BWP is from 0 to BWP-size-1, then the value of S can range from 0 to BWP-size-2. In this embodiment of the present disclosure, if L RBs are allocated to the first type of terminal, then the value of S ranges from 0 to BWP-size-2-L.

[0112] Lmax represents the maximum number of Restricted Blocks (RBs) supported by the first type of terminal. For example, Lmax can be determined based on the second bandwidth supported by the first type of terminal. For instance, Lmax could be equal to the number of RBs corresponding to the second bandwidth supported by the first type of terminal. Assuming the second bandwidth supported by the first type of terminal is 5MHz, then Lmax is equal to the floor of the quotient between 5MHz and the bandwidth value of a single RB.

[0113] The value of L can be any positive integer.

[0114] BWP-size can also be considered as the number of RBs contained in the active BWP of the first type of terminal.

[0115] In this embodiment of the disclosure, both the base station and the first type of terminal know the conversion relationship between RIV and S and L. After the base station completes the resource allocation, it can determine the RIV according to the conversion relationship. After receiving the RIV, the first type of terminal determines the S and L represented by the currently received RIV according to the conversion relationship, thereby knowing the RB allocated by the base station for the first type of terminal.

[0116] As can be seen in this embodiment, the RIV is determined based on Lmax, and has the characteristics of simple RIV numbering and low bit overhead.

[0117] In some embodiments, the BWP-size may be determined based on a first bandwidth supported by the first type of terminal. For example, the BWP-size may be equal to the number of RBs corresponding to the first bandwidth supported by the first type of terminal. Assuming that the first bandwidth supported by the first type of terminal is 20MHz, then the BWP-size may be equal to 20MHz, or the BWP-size may be the floor function of the quotient between 20MHz and the bandwidth value of a single RB.

[0118] In New Radio (NR) communication systems, the maximum resources that a terminal can be allocated can be the same as the size of the BWP (Bandwidth, Width, and Portability) bandwidth. Therefore, in type 1 resource allocation, the amount of resources supported by the terminal is equal to the bandwidth of the BWP.

[0119] However, since the maximum allocated resources supported by the eRedCap terminal are not equal to the width of the BWP allocated to the terminal, if the resource allocation instruction and DCI bits are still determined based on the BWP bandwidth, it will lead to an increase in terminal DCI overhead.

[0120] In view of this, the resource allocation method for eRedCap terminal type 1 is enhanced to reduce DCI overhead.

[0121] For example, the response is a first-class terminal, which determines resource allocation based on the terminal's transmit / receive bandwidth and / or BWP bandwidth. This first-class terminal includes, but is not limited to, eRedCap terminals.

[0122] The first type of terminal supports a different range of frequency (RF) transmit / receive bandwidth than the baseband processing bandwidth. For example, the eRedCap terminal has an RF transmit / receive bandwidth of 20MHz and a baseband processing bandwidth of 5MHz.

[0123] The initial RB allocated to the terminal can be any RB in the BWP, and the total number of consecutive RBs allocated to the terminal shall not exceed the total number of RBs included in the terminal's baseband processing bandwidth.

[0124] The resource allocation indication is jointly encoded based on the terminal's transmit / receive bandwidth and / or BWP bandwidth. This joint encoding indicates the starting RB allocated to the terminal and the number of consecutive RBs. This joint encoding is one type of the aforementioned RIV.

[0125] Specifically, BWP_size is the total number of RBs contained in BWP, and Lmax is the maximum number of RBs allocated to the terminal and distributed continuously. Lmax is determined by the baseband processing bandwidth of the terminal.

[0126] If S <= BWP_size - Lmax, then RIV = S * Lmax + L;

[0127] If S>BWP_size-Lmax, then RIV=(BWP_size-Lmax)*Lmax+{(Lmax-1)+(Lmax-2)+…+(Lmax-(S-(BWP_size-Lmax)));

[0128] The number of bits occupied by the resource allocation field in DCI can be determined by the baseband processing bandwidth of the terminal and the bandwidth of the BWP.

[0129] For example, the number of bits occupied by the resource allocation field can at least indicate the maximum index value of the RIV.

[0130] like Figure 7 As shown, this disclosure provides a resource processing apparatus, wherein the apparatus includes:

[0131] The allocation module 110 is configured to allocate resources to the first type of terminal in response to the first type of terminal, and to allocate resources according to the bandwidth supported by the first type of terminal.

[0132] In some embodiments, the resource processing apparatus may be included in a base station.

[0133] The base station includes, but is not limited to, eNB and / or gNB.

[0134] In some embodiments, the resource processing apparatus further includes a storage module; the storage module may be used at least to store resource allocation information generated by resource allocation.

[0135] In some embodiments, the allocation module 110 may be a program module; after the program module is executed by the processor, it can perform the above-mentioned resource allocation operation.

[0136] In other embodiments, the allocation module 110 may be a hardware-software hybrid module; the hardware-software hybrid module includes, but is not limited to, a programmable array; the programmable array includes, but is not limited to, field-programmable arrays and / or complex programmable arrays.

[0137] In some embodiments, the allocation module 110 may include: a pure hardware module; the pure hardware module includes, but is not limited to, an application-specific integrated circuit.
