Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a resource indication method and apparatus. Background Technology

[0002] With the development of communications, the International Telecommunication Union (ITU) defined the massive machine-type communications (mMTC) standard. Currently, the standard refers to user equipment (UE) performing mMTC services as reduced-capability (REDCAP) UEs, meaning UEs with low complexity or low capability. These UEs may have lower complexity than other UEs in terms of bandwidth, power consumption, and number of antennas, such as occupying narrower bandwidth, consuming less power, and having fewer antennas. This type of UE can also be called a lightweight terminal device (NR light, NRL).

[0003] Because REDCAP UEs occupy relatively narrow bandwidth, if there are many REDCAP UE users, they will all be concentrated in the narrow bandwidth, which can easily cause multiple REDCAP UEs to compete for bandwidth, leading to service congestion. Summary of the Invention

[0004] This application provides a resource indication method and apparatus to solve the problem that when a large number of first terminal devices are concentrated in a narrow bandwidth, it can easily cause service congestion.

[0005] Firstly, this application provides a resource indication method, which can be executed by a terminal device, such as a low-capacity terminal like the aforementioned REDCAP UE. The method includes: a first terminal device determining a first resource, wherein the number of resources included in the first resource is greater than the number of resources supported by the first terminal device; the first terminal device receiving first information indicating the position of a second resource within the first resource, wherein the number of resources included in the second resource is less than or equal to the number of resources supported by the first terminal device; the first terminal device receiving second information indicating the position of a third resource within the second resource; and the first terminal device performing information transmission on the third resource. Here, the first terminal device can be a low-capacity terminal, such as a REDCAP UE.

[0006] In this embodiment, the access network device can configure the initial bandwidth area of ​​the first terminal device at any location within a broadband resource. This means the initial bandwidth area of ​​the first terminal device is no longer fixed at a single location, and the scheduling resources for the first terminal device are not limited to the area supported by its capabilities or the limited resources configured. In this way, the scheduling resources of different first terminal devices can be distributed across different locations within the broadband resource, thereby avoiding service congestion and achieving better load balancing.

[0007] In one possible design, the first terminal device can be a low-capability terminal, such as REDCAP UE.

[0008] In one possible design, the first terminal device sends a first reporting information, which is a UE feature of the first terminal device. The first reporting information indicates the minimum number of antennas and the maximum number of transmission layers that the terminal device can support. For example, the first terminal device can support a minimum of 1 or 2 antennas and a maximum of 1 or 2 transmission layers. The first reporting information includes 2 bits. The first bit of the first reporting information indicates that the first terminal device supports a minimum of 1 antenna and a maximum of 1 transmission layer. The second bit of the first reporting information indicates that the first terminal device supports a minimum of 2 antennas and a maximum of 1 transmission layer. The third bit of the first reporting information indicates that the first terminal device supports a minimum of 2 antennas and a maximum of 2 transmission layers. The fourth bit of the first reporting information is a reserved state. Alternatively, the fourth bit of the first reporting information indicates that the capabilities of the first terminal device and the second terminal device are the same. The second terminal device can be a terminal device supported by NR R15, or a terminal device with capabilities higher than the first terminal device.

[0009] In one possible design, the first terminal device can receive first information and / or second information via random access response information. For example, the random access response information can be at least one of random access physical downlink control channel response information, random access physical downlink shared channel response information, etc., and includes uplink grant information. Through the above design, the first terminal device can determine a third resource for information transmission based on the random access response information.

[0010] In one possible design, the number of bits for the second information can be determined based on the number of resources supported by the first terminal device or the number of resources included in the second resource. For example, the number of bits for the second information can satisfy the following formula:

[0011]

[0012] Wherein, N is the number of resources of the first terminal device, or N is the number of resources included in the second resource.

[0013] The above design avoids bit redundancy, thereby reducing signaling overhead.

[0014] In one possible design, the first terminal device can acquire first information and second information when a first characteristic is met. The first characteristic is that the number of resources included in the second resource is less than or equal to a reference value. The reference value is a preset value. Alternatively, the reference value is the number of resources included in the first resource. The first characteristic is that the bandwidth (BWP) of the first terminal device is greater than or equal to the bandwidth that the first terminal device can support. For example, the BWP is an initial BWP. Through the above design, the first terminal device can determine the method for scheduling resources based on the resource information.

[0015] In one possible design, the first terminal device acquires third information when the first characteristic is not satisfied. This third information carries at least one of the following: the location information of the third resource within the second resource, and the frequency hopping information for information transmission by the first terminal device. Alternatively, the first terminal device acquires third information when the second characteristic is satisfied. This third information carries at least one of the following: the location information of the third resource within the second resource, and the frequency hopping information for information transmission by the first terminal device. Through this design, the first terminal device can support two resource indication methods, thereby improving flexibility.

[0016] In one possible design, the first terminal device can further determine the position and / or length of the fourth resource based on the position and / or length of the second resource within the first resource, and then the first terminal device detects control information on the fourth resource. Through this design, the first terminal device can determine the fourth resource.

[0017] Secondly, this application provides a resource indication method, which can be executed by a terminal device, such as a low-capacity terminal like the aforementioned REDCAP UE. The method includes: a first terminal device determining a first resource, wherein the number of resources included in the first resource is greater than the number of resources supported by the first terminal device; the first terminal device receiving fourth information, the fourth information indicating the location information and resource size information of a third resource within the first resource, wherein the number of resources included in the third resource is less than or equal to the number of resources supported by the first terminal device; and the first terminal device performing information transmission on the third resource. Here, the first terminal device can be a low-capacity terminal, such as a REDCAP UE.

[0018] In this embodiment, the access network device can configure the scheduling resources of the first terminal device at any location within a broadband resource, so that the scheduling resources of the first terminal device are not limited to the area supported by the capability or the limited resources configured. In this way, the scheduling resources of different first terminal devices can be distributed at different locations within the broadband resource, thereby avoiding service congestion and achieving better load balancing.

[0019] In one possible design, the terminal device can receive the fourth information via random access response information. For example, the random access response information may be at least one of random access physical downlink control channel response information, random access physical downlink shared channel response information, etc., and the random access response information includes uplink grant information. Through the above design, the first terminal device can determine the third resource for information transmission based on the random access response information.

[0020] In one possible design, the number of bits in the fourth information is determined based on the number of resources included in the first resource and a first value. The first value is greater than or equal to the number of resources included in the third resource, and less than or equal to the number of resources that the first terminal device can support.

[0021] In one possible design, the first terminal device can specifically receive the fourth information when a first characteristic is met. The first characteristic is that a first value is less than or equal to a reference value, where the reference value is a preset value, or the reference value is the number of resources included in the first resource. The first value is greater than or equal to the number of resources included in the third resource, and less than or equal to the number of resources that the first terminal device can support. For example, the first characteristic is that the bandwidth limit (BWP) of the first terminal device is greater than or equal to the bandwidth that the first terminal device can support. For example, the BWP is an initial BWP. Through the above design, the first terminal device can determine the method of scheduling resources based on resource information.

[0022] In one possible design, the first terminal device can also acquire third information when the first characteristic is not satisfied. This third information carries at least one of the following: the location information of the third resource within the first resource, and the frequency hopping information for information transmission by the first terminal device. Through this design, the first terminal device can support two resource indication methods, thereby improving flexibility.

[0023] Thirdly, this application provides a resource indication method, which includes: an access network device determining first information and second information. The first information indicates the location of the second resource within the first resource, and the number of resources included in the first resource is greater than the number of resources that the first terminal device can support. The number of resources included in the second resource is less than or equal to the number of resources that the first terminal device can support; the second information indicates the location of the third resource within the second resource, and the number of resources included in the second resource is greater than or equal to the number of resources included in the third resource. The access network device sends the first information and the second information to the first terminal device. The access network device transmits information with the first terminal device on the third resource, such as sending information to the first terminal device or receiving information sent by the first terminal device. The first resource is a usable resource determined by the first terminal device. Here, the first terminal device can be a low-capability terminal, such as a REDCAP UE.

[0024] In one possible design, the access network device can send first information and / or second information via random access response information. For example, the random access response information may be at least one of random access physical downlink control channel response information, random access physical downlink shared channel response information, etc., and the random access response information includes uplink grant information.

[0025] In one possible design, the number of bits for the second information can be determined based on the number of resources supported by the first terminal device or the number of resources included in the second resource. For example, the number of bits for the second information can satisfy the following formula:

[0026]

[0027] Wherein, N is the number of resources of the first terminal device, or N is the number of resources included in the second resource.

[0028] The above design avoids bit redundancy, thereby reducing signaling overhead.

[0029] Fourthly, this application provides a resource indication method, which includes: an access network device determining fourth information and sending the fourth information to a first terminal device. The fourth information indicates the location information and resource size information of a third resource within a first resource. The first resource includes a number of resources greater than the number of resources supported by the first terminal device, and the third resource includes a number of resources less than or equal to the number of resources supported by the first terminal device. The access network device transmits information with the first terminal device on the third resource, such as sending information to or receiving information sent by the first terminal device. The first resource is a usable resource determined by the first terminal device. Here, the first terminal device can be a low-capability terminal, such as a REDCAP UE.

[0030] In this embodiment, the scheduling resources of the first terminal device are not limited to the area that the capability can support or are configured within a small number of resources, thereby avoiding service blockage and achieving better load balancing.

[0031] In one possible design, the access network device can send the fourth information via random access response information. For example, the random access response information can be at least one of random access physical downlink control channel response information, random access physical downlink shared channel response information, etc., and includes uplink grant information. Through this design, the first terminal device can determine the third resource for information transmission based on the random access response information.

[0032] In one possible design, the number of bits in the fourth information can be determined based on the number of resources included in the first resource and the number of resources included in the second resource, wherein the number of resources included in the second resource is greater than or equal to the number of resources included in the third resource, and less than or equal to the number of resources that the first terminal device can support. This design avoids bit redundancy, thereby reducing signaling overhead.

[0060] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0061] The resource indication method provided in this application can be applied to various communication systems, such as the Internet of Things (IoT), narrowband Internet of Things (NB-IoT), long term evolution (LTE), fifth-generation (5G) communication systems, hybrid LTE and 5G architectures, 5G new radio (NR) systems, and other new communication systems emerging in future communication development. The 5G communication system described in this application can include at least one of non-standalone (NSA) and standalone (SA) 5G communication systems. The communication system can also be a public land mobile network (PLMN), a device-to-device (D2D) network, a machine-to-machine (M2M) network, or other networks.

[0062] The resource indication method provided in this application can be applied to downlink signal transmission, uplink signal transmission, and D2D signal transmission. For downlink signal transmission, the transmitting device is an access network device, and the corresponding receiving device is a terminal device. For uplink signal transmission, the transmitting device is a terminal device, and the corresponding receiving device is an access network device. For D2D signal transmission, the transmitting device is a terminal device, and the corresponding receiving device is also a terminal device. The embodiments of this application do not limit the direction of signal transmission.

[0063] Communication between access network devices and terminal devices, as well as between terminal devices, can be achieved through licensed spectrum, unlicensed spectrum, or a combination of both. Communication between access network devices and terminal devices, as well as between terminal devices, can also be achieved through spectrum below 6 GHz, spectrum above 6 GHz, or a combination of both. This application does not limit the spectrum resources used between access network devices and terminal devices.

[0064] like Figure 1A As shown, the communication system used in this application embodiment may include a core network device 210, an access network device 220, and at least one terminal device, such as... Figure 1A Terminal devices 230 and 240 are included. The terminal devices connect wirelessly to the access network equipment, and the access network equipment connects wirelessly or via a wired connection to the core network equipment. Alternatively, as... Figure 1B As shown, the communication system applied in this application embodiment may include core network equipment, at least two access network devices, and at least one terminal device. The core network equipment and access network devices may be independent and different physical devices, or the functions of the core network equipment and the logical functions of the access network devices may be integrated on the same physical device, or a single physical device may integrate some of the functions of the core network equipment and some of the functions of the access network equipment.

Figure 1A and Figure 1B Not shown in the diagram. This application embodiment does not limit the number of core network devices, access network devices, and terminal devices included in the communication system.

[0065] The terminal device involved in the embodiments of this application is an entity on the user side used to receive or transmit signals. The terminal device can be a device that provides voice and data connectivity to the user, such as a handheld device or vehicle-mounted device with wireless connectivity. The terminal device can also be other processing devices connected to a wireless modem. The terminal device can communicate with one or more core networks through a radio access network (RAN). The terminal device can also be referred to as a wireless terminal, 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, etc. The terminal device can be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal, for example, a portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile device that exchanges voice and data with the radio access network. For example, the terminal device can also be a Personal Communication Service (PCS) telephone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), and other devices. Common terminal devices include mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), and wearable devices such as smartwatches, smart bracelets, and pedometers, but the embodiments of this application are not limited to these. The terminal devices involved in the embodiments of this application can also be terminal devices that will appear in future evolution PLMNs, and the embodiments of this application are not limited in this regard. The embodiments of this application do not limit the specific technologies and specific device forms used in the terminal devices.

[0066] Furthermore, in this embodiment, the terminal device can also be a terminal device in an IoT system. IoT is an important component of future information technology development, and its main technical feature is connecting objects to networks through communication technologies, thereby realizing an intelligent network of human-machine interconnection and object-to-object interconnection. In this embodiment, IoT technology can achieve massive connectivity, deep coverage, and low terminal power consumption through technologies such as narrowband (NB).

[0067] In addition, in this embodiment, the terminal device may also include sensors such as smart printers, train detectors, and gas stations. Its main functions include collecting data (for some terminal devices), receiving control information and downlink data from network devices, and sending electromagnetic waves to transmit uplink data to network devices.

[0068] The access network device involved in the embodiments of this application is an entity on the network side used for transmitting or receiving signals. The network device in the embodiments of this application can be a device in a wireless network, such as a RAN node that connects a terminal to the wireless network. For example, the network device can be an evolved Node B (eNB or e-NodeB) in LTE, a new radio controller (NR controller), a gNode B (gNB) in a 5G system, a centralized unit (CU), a new radio base station, a remote radio module, a micro base station, a relay, a distributed unit (DU), a femtobase station, a transmission reception point (TRP) or transmission point (TP), or any other wireless access device, but the embodiments of this application are not limited to these. The network device can cover one or more cells.

[0069] Access network equipment and terminal equipment can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can also be deployed in the air on aircraft, drones, balloons, and satellites. The embodiments of this application do not limit the application scenarios of the access network equipment and terminal equipment.

[0070] The network architecture and business scenarios described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0071] To cope with the explosive growth of mobile data traffic, the massive number of mobile communication device connections, and the continuous emergence of various new services and application scenarios, 5G mobile communication systems have emerged. The ITU has defined three major application scenarios for 5G and future mobile communication systems: enhanced mobile broadband (eMBB), ultra-reliable and low-latency communications (URLLC), and mMTC.

[0072] Typical eMBB services include ultra-high-definition video, augmented reality (AR), and virtual reality (VR). These services are characterized by large data transmission volumes and high transmission rates. Typical URLLC services include wireless control in industrial manufacturing or production processes, motion control for autonomous vehicles and drones, and haptic interaction applications such as remote repair and remote surgery. These services are characterized by requirements for ultra-high reliability, low latency, relatively small data transmission volumes, and bursty nature. Typical mMTC services include smart grid distribution automation and smart cities. These services are characterized by a large number of networked devices, relatively small data transmission volumes, and low sensitivity to transmission latency. These mMTC terminals need to meet the requirements of low cost and very long standby times.

[0073] Different services have different requirements for mobile communication systems. How to better support the data transmission needs of multiple different services simultaneously is a technical problem that current 5G mobile communication systems need to solve. For example, how to simultaneously support mMTC and eMBB services, or simultaneously support URLLC and eMBB services.

[0074] Research on mMTC in 5G standards has not yet been widely carried out.

[0075] Currently, the standard refers to UEs for mMTC services as REDCAP UEs, which are low-complexity or low-capability UEs. These UEs may be less complex than other UEs in terms of bandwidth, power consumption, and number of antennas, such as narrower bandwidth, lower power consumption, and fewer antennas. These UEs can also be called NRL UEs.

[0076] Currently, UE random access includes two types: contention-based and non-contention-based.

[0077] like Figure 2 As shown, the contention-based random access process of 4-step random access includes:

[0078] In S201, the UE sends a random access preamble, also known as the first message (Msg1), to the access network device. The purpose of the random access preamble is to notify the access network device that there is a random access request and to enable the access network device to estimate the transmission delay between itself and the UE. This allows the access network device to calibrate uplink timing and inform the UE of the calibration information through a timing advance command.

[0079] In S202, after detecting the random access preamble, the access network device sends a random access response (RAR) to the UE, which can also be called the second message (Msg2). The random access response may include, but is not limited to, the sequence number of the random access preamble received in S201, the timing advance instruction, uplink resource allocation information, and the cell radio network temporary identifier.

[0080] In S203, the UE receives a random access response. If the random access preamble indicated by the sequence number of the random access preamble in the random access response is the same as the random access preamble sent by the UE to the access network device in S201, then the UE considers the random access response to be a random access response specific to itself, meaning the UE has received the random access response for itself. After receiving the random access response, the UE sends an uplink message on the uplink channel resource indicated in the random access response, such as sending the physical uplink shared channel (PUSCH) in Msg3, also known as the third message (Msg3). Msg3 may carry a unique user identifier.

[0081] In S204, the access network device receives the uplink message from the UE and returns a conflict resolution message, also known as the fourth message (Msg4), to the access UE. The access network device will carry the unique user identifier from Msg3 in the conflict resolution message to specify the UE that has successfully accessed the network, while other UEs that have not successfully accessed the network will re-initiate random access.

[0082] In a competition-based process, access network devices cannot obtain the UE's identification information before Msg3.

[0083] like Figure 3 As shown, the non-contention-based random access procedure includes:

[0084] S301, the access network equipment allocates a random access preamble to the UE.

[0085] S302, the UE sends a dedicated random access preamble to the access network equipment.

[0086] S303, the access network device sends a RAR to the UE.

[0087] In a non-contention-based random access process, the access network device can obtain the UE's identification information before sending the RAR message. Based on this identification information, the access network device can obtain information about the UE, such as the type of terminal the UE belongs to, such as an existing terminal (eMBB terminal), a REDCAP terminal, or a traditional terminal.

[0088] The RAR includes uplink transmission scheduling (UL grant) information from the access network equipment. This includes a 14-bit frequency domain resource allocation (FDRA) field. The FDRA field indicates the starting location and length of the uplink transmission frequency domain resources, as shown in Table 1.

[0090]

[0091] The location of uplink transmission frequency domain resources is determined by a joint coded value indicating the starting resource location and length. If the number of uplink transmission allocatable resources, i.e., the number of physical resource blocks (PRBs) in the initial uplink bandwidth region, is... The state that FDRA needs to indicate is: The number of bits required for FDRA is [number missing]. If the allocable resource bandwidth is ≤180RBs, the NR protocol specifies that the frequency domain resource indicator field will be truncated to the specified length according to DCI format 0_0. The least significant bits (LSB) are retained.

[0092] The UL grant also includes a 1-bit frequency hopping flag to indicate whether frequency hopping is involved in this uplink transmission. If frequency hopping is involved, the most significant bits (MSB) will be allocated to either 1 or 2 bits, i.e., N, depending on the system bandwidth. UL,hop This indicates the offset of the second hop's frequency domain location relative to the first hop. As shown in Table 2, if the available resource bandwidth... At that time, N UL,hopFor 1 bit, if the available resource bandwidth At that time, N UL,hop It is 2 bits.

[0093] Table 2

[0094]

[0095] The following examples illustrate the number of bits required to indicate the location of uplink transmission frequency domain resources under different sub-carrier spacings (SCS) and bandwidths. The low-frequency band (frequency range 1, FR1) can be shown in Table 3, and the high-frequency band (frequency range 2, FR1) can be shown in Table 4.

[0096] Table 3

[0097]

[0098] Table 4

[0099]

[0100] According to Tables 3 and 4 above, under some bandwidth configurations (e.g., less than 20MHz in Table 3 or 100MHz in Table 4), the number of bits required to indicate the location of uplink transmission frequency domain resources is less than 14 bits.

[0101] Taking the first terminal device in FR1 as an example. If the maximum bandwidth supported by the first terminal device is below 20MHz, the corresponding maximum number of RBs is approximately less than or equal to 106. The number of bits required to indicate the location of uplink transmission frequency domain resources is at most 13 bits, and there will be at least 1 bit remaining unused in the frequency domain resource indication field. For small bandwidths (such as 5MHz / 10MHz), or high frequencies (FR2) with large SCS (60 / 120 / 240kHz), there are more idle bits. For example, when SCS = 60kHz and bandwidth = 20MHz including 24RBs, the frequency domain resource indication requires 9 bits. Frequency hopping information requires 2 bits, and the resource offset value requires 4 bits. The first terminal device can be a low-capability terminal device, such as a REDCAP UE.

[0102] Because Type I terminal devices support a narrow bandwidth, when there are a large number of users on these devices, the traffic is concentrated within that narrow bandwidth, causing service congestion and increased transmission / access latency. Type I terminal devices can be low-capacity devices, such as REDCAP UEs.

[0103] Based on this, embodiments of this application provide a resource indication method and apparatus to address the problem of service congestion easily caused by REDCAP UE. The method and apparatus are based on the same inventive concept. Since the principles by which the method and apparatus solve the problem are similar, their implementations can be mutually referenced, and repeated details will not be elaborated further.

[0104] In this embodiment, the location of the second resource within the first resource can be indicated in the RAR UL grant, where the size of the first resource is larger than the size of resources that the first terminal device can support. The number of resources included in the second resource is less than or equal to the number of resources that the first terminal device can support. For example... Figure 4 As shown, the left side represents the first resource, and the right side represents the second resource, with their upper boundaries aligned. This ensures that the range of resources available for allocation by the first terminal device (e.g., the second resource) is not limited to what its capabilities support (if the first terminal device has relatively low capabilities) or configured within a narrow bandwidth, thereby avoiding service congestion and achieving better load balancing. The first resource can be the initial BWP resource for broadcast message notification. For example, the first resource can also be the initial BWP resource for the second terminal device, where the bandwidth supported by the second terminal device is greater than that supported by the first terminal device. The bandwidth supported by the first terminal device can be understood as the maximum bandwidth supported by the first terminal device. Furthermore, the first resource can also be a frequency domain resource for the access network device, such as a carrier wave.

[0105] It should be understood that in the embodiments of this application, "at least one" means one or more, and "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can represent: a, b, c, a and b, a and c, b and c, or a, b, and c, where a, b, and c can be single or multiple.

[0106] In addition, it should be understood that in the description of this application, the words "first" and "second" are used only for the purpose of distinguishing descriptions and should not be construed as indicating or implying relative importance, order, or number.

[0107] The method provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0108] Example 1: See Figure 5This is a flowchart illustrating a resource indication method provided in this application. The method includes:

[0109] S501, the access network device determines first information and second information. The first information indicates the position of the second resource within the first resource, and the number of resources included in the first resource is greater than the number of resources supported by the first terminal device. The number of resources included in the second resource is less than or equal to the number of resources supported by the first terminal device. The second information indicates the position of the third resource within the second resource, and the number of resources included in the second resource is greater than or equal to the number of resources included in the third resource. For example, the content indicated by the second information may be as follows: Figure 6 As shown.

[0110] For example, the first terminal device can be a low-capability terminal device, such as REDCAP UE.

[0111] The size of the first, second, and third resources can be understood as the time domain range, frequency domain range, etc., or as the number of resources included.

[0112] In this embodiment, the first, second, and third resources can be time-domain resources, frequency-domain resources, spatial-domain resources, code-domain resources, power resources, etc. For example, the resource units of time-domain resources can be radio frames, subframes, half-frames, time slots, mini-time slots, symbols, etc. The resource units of frequency-domain resources can be sub-carriers, resource blocks (RBs), resource elements (REs), resource element groups (REGs), REG bundles, control channel elements (CCEs), and carriers. For example, if the bandwidth is 20MHz and the subcarrier spacing is 15kHz, the number of resource blocks included can be 106 RBs.

[0113] In one exemplary description, the size of resources that the first terminal device can support (or allocate) can be understood as the number of resource blocks included in the supported bandwidth. The number of resource blocks included in the supported bandwidth can be the maximum number of frequency domain resource blocks that the first terminal device can occupy when transmitting and / or receiving. For example, the maximum bandwidth of the signal that the first terminal device can receive, and / or the maximum bandwidth of the signal that the first terminal device can transmit. For instance, if the supported bandwidth is 20MHz and the subcarrier spacing is 15kHz, the supported number of resource blocks is 106 RBs.

[0114] The following example uses the first resource as a frequency domain resource to illustrate the first resource.

[0115] In one implementation, the first terminal device can obtain information about the first resource through system messages broadcast by the access network device. The first resource can also be the initial BWP of the second terminal device. For example, the UE capabilities of the second terminal device are higher than those of the first terminal device. Capabilities include at least one of the following: supported bandwidth, data processing speed, supported number of antennas, and maximum supported modulation and coding scheme.

[0116] In another implementation, the first resource can be a carrier wave used by the access network device. In this implementation, the first resource can be a predefined resource location and bandwidth. Optionally, the first terminal device can obtain information about the first resource before joining the network.

[0117] In another implementation, the first resource can also be notified by the access network device via signaling. For example, the access network device can instruct the user to use a frequency range via system messages or broadcast messages. The first terminal device obtains information about the first resource by receiving system messages or broadcast messages.

[0118] In one implementation, the size of the second resource can be the size of the resources that the first terminal device can support (or allocate).

[0119] In some embodiments, the size of the second resource may be determined based on the capabilities of the first terminal device, or it may be configured by the access network device. Where the size of the second resource is determined based on the capabilities of the first terminal device, it may mean that the size of the second resource is the maximum value of resources that the first terminal device can support for receiving and / or transmitting signals. Where the size of the second resource is configured by the access network device, it may mean that the access network device instructs the first terminal device, through signaling, on the range of resource sizes for receiving and / or transmitting signals, or that the access network device schedules the first terminal device to receive and / or transmit signals within the range of resource sizes.

[0120] Taking the second resource as a frequency domain resource as an example, the frequency domain range of the second resource can be determined based on the capabilities of the first terminal device or configured by the access network device. Where the frequency domain range of the second resource is determined based on the capabilities of the first terminal device, it can refer to the maximum bandwidth or maximum number of resources that the first terminal device can support for receiving and / or transmitting signals. Where the frequency domain range of the second resource is configured by the access network device, it can refer to the maximum bandwidth or maximum number of resources that the access network device instructs the first terminal device to receive and / or transmit signals through signaling, or the access network device schedules the maximum bandwidth or maximum number of resources that the first terminal device can receive and / or transmit signals.

[0121] S502, the access network device sends first information and second information to the first terminal device. Correspondingly, the first terminal device receives the second information.

[0122] S503, the first terminal device determines the first resource.

[0123] It should be noted that there is no strict order between steps S502 and S503. Step S502 can be executed first and then step S503, or step S503 can be executed first and then step S502, or steps S502 and S503 can be executed simultaneously.

[0124] S504, the first terminal device transmits information on the third resource. For example, the first terminal device sends information on the third resource. Correspondingly, the access network device receives information on the third resource. For example, the first terminal device receives information on the third resource. Correspondingly, the access network device sends information on the third resource.

[0125] For example, the information transmitted by the first terminal device on the third resource may be control information, data information, paging information, random access information, random access response information, broadcast information, etc. Control information may include uplink control information and downlink control information. Data information may include uplink data information and downlink data information.

[0126] In this embodiment, the access network device can configure the second resource at any location of the first resource, wherein the size of the first resource is larger than the size of the resources that the first terminal device can support, and the size of the second resource does not exceed the size of the resources that the first terminal device can support. This allows the second resource to no longer be fixed in a fixed location, thus the scheduling resources of the first terminal device are not limited to the area supported by its capabilities or the limited number of resources configured. In this way, the scheduling resources of different first terminal devices can be distributed at different locations of broadband resources, thereby avoiding service congestion and achieving better load balancing.

[0127] In one exemplary embodiment, the second information can be the frequency domain resource allocation in the RAR. It should be noted that currently the number of bits for frequency domain resource allocation is fixed at 14 bits, but in this embodiment, the number of bits for the second information can be determined based on the amount of resources in the first terminal device or the size of the second resource. For example, the number of bits for the second information can satisfy the following formula: Wherein, N is the number of resources for transmitting information by the first terminal device, which can also be understood as the number of uplink transmission allocable resources by the first terminal device, the number of PRBs in the initial BWP of the first terminal device, or the number of resources included in the second resource, or the maximum number of resources supported by the first terminal device.

[0128] In one implementation, the second information can be obtained from the current PUSCH frequency domain resource allocation. Each bit is used for indication. The random access response also includes first information. The number of bits required for the first and second information is less than or equal to 14 bits. Alternatively, the number of bits required for the first and second information is less than or equal to the number of bits included in the frequency domain resource allocation indication field of the second terminal device. Through the above implementation method, signaling overhead can be reduced.

[0129] In one implementation, the first information and / or the second information are transmitted in a Random Access Response (RAR). For example, the access network device can send the first information and the second information to a first terminal device via the RAR.

[0130] For example, the random access response information may be at least one of the following: random access physical downlink control channel (PDCCH) response information, random access physical downlink shared channel (PDSCH) response information, etc., and the random access response information includes uplink grant information.

[0131] In one exemplary illustration, the information included in the UL grant in the RAR may be as shown in Table 5.

[0132] Table 5

[0133]

[0134] Optionally, the UL grant information may also include other information, such as frequency hopping identifier, MCS, TPC command for PUSCH, etc., as detailed in Table 1 above.

[0135] In one implementation, the number of bits included in the license information of the RAR is less than or equal to the number of bits included in the RAR license information of the previous version. For example, the previous version is NR R15.

[0136] In one implementation, the number of bits included in the license information in the RAR is less than or equal to 28 bits.

[0137] In one implementation, the number of bits included in the frequency domain resource allocation indication field of the authorization information in the RAR is less than 14 bits. Furthermore, the authorization information in the RAR includes first information, which is information indicating the location of the second resource within the first resource.

[0138] The resource indication method of this application embodiment will be described below with the example of the third resource being the uplink scheduling resource of the first terminal device, the second resource being the bandwidth that the first terminal device can support, and the bandwidth of the first resource being greater than the bandwidth of the second resource.

[0139] If the existing FDRA bit count is used, because the UE supports a smaller bandwidth, the required number of frequency domain resource allocation indication bits is less than the existing FDRA bit count, which will result in idle bits in the PUSCH frequency domain resource allocation field. In this embodiment, these idle bits can be used to indicate the frequency domain offset value of the second resource within the first resource (i.e., the first information).

[0140] In one exemplary embodiment, the first information may indicate the starting position S1 of the second resource. The second information may indicate the offset S2 of the starting position of the third resource relative to the starting position of the second resource and the length L of the third resource.

[0141] Wherein, S1 can be the offset value of the minimum RB index of the allocatable resource (i.e., the second resource) of the first terminal device relative to the reference point. In one example, the first resource can be the initial bandwidth area resource configured by the access network device for the first terminal device, and the reference point can be the minimum RB index of the allocatable resource of the initial bandwidth area resource. In another example, the first resource can be the frequency domain range indicated by the access network device, and the reference point can be the resource location indicated by the access network device.

[0142] The first information can indicate S1. S1 can be a pre-configured value (e.g., an integer multiple of RB, 10M, 20M, BWP / 4, BWP / 2, etc.). Alternatively, the first information can also include an indication value, and S1 can be a value calculated according to this indication value based on a preset rule. For example, S1 can be equal to the indication value carried in the first information multiplied by a multiple of the initial bandwidth of the first terminal device. For example, S1 can be equal to the indication value carried in the first information multiplied by the bandwidth supported by the first terminal device. For example, S1 can be equal to the indication value carried in the first information multiplied by a multiple of the bandwidth supported by the first terminal device. S1 can use 3 bits to indicate the offset value of the starting position of the second resource relative to the starting position of the first resource. The offset value can be a predefined value, a value indicated in advance by the access network device through signaling, or a value calculated from the indication carried in the first information using a predefined method.

[0143] For example, the offset value can be determined in the following predefined way: the offset value can be determined based on the number of RBs included in the first resource and the number of candidate values ​​for the offset value. For example, S1 equals W / the number of candidate values ​​for the offset value. For example, W is the number of RBs included in the initial BWP resource (such as the first resource) configured by the access network device. For example, W is 270. The number of candidate values ​​for the offset value is 8. Then the offset value corresponding to the value i indicated by S1 = W / 8 * i. Optionally, to make the result an integer, you can choose to round up or down. Or, the offset value = (W - the bandwidth supported by the first terminal device) / (8 - 1) * i. Or, the offset value = (W - the size of the second resource) / (8 - 1) * i. The bandwidth supported by the first terminal device (such as the second resource or a preset value or a pre-configured value) can be determined based on the maximum bandwidth of the first terminal device's ability to transmit signals, or based on the maximum bandwidth of the first terminal device's ability to receive signals, or the maximum bandwidth currently supported by the first terminal device for transmission and reception as indicated by the access network device, etc.

[0144] The second piece of information can indicate S2 and L. For example, S2 and L can be indicated using 11 bits.

[0145] In some embodiments, the first terminal device obtains the UL grant information provided in this application embodiment when the first characteristic is met, including first information and second information. When the second characteristic is met, the first terminal device can obtain UL grant information defined by existing protocols, such as third information. The third information carries at least one of the following: the location information of the third resource in the second resource, and frequency hopping information. For example, the frequency hopping information may include at least one of frequency hopping indication information and frequency hopping offset value. The frequency hopping indication information is used to indicate whether frequency hopping is required. The first characteristic is that the BWP bandwidth is greater than or equal to the bandwidth supported by the first terminal device. For example, the BWP is an initial BWP. The second characteristic is that the BWP bandwidth is less than or equal to the bandwidth supported by the first terminal device. For example, if the first terminal device can support a 20MHz bandwidth, the first characteristic is that the initial BWP bandwidth of the first terminal device is greater than or equal to 20MHz. The second characteristic is that the initial BWP bandwidth of the first terminal device is less than or equal to 20MHz.

[0146] In other embodiments, the first terminal device can support acquiring both first and second information, as well as third information. That is, the acquired UL grant information can include the first and second information, and also the third information. For example, when the initial bandwidth of the first terminal device is small (e.g., 5MHz / 10MHz), or when it operates at a high frequency (e.g., FR2), or when its SCS is large (e.g., 60 / 120 / 240kHz), the acquired UL grant information can include the first and second information, and also the third information. For example, SCS = 60kHz, bandwidth = 20MHz, including 24RBs, FDRA requires 9 bits, frequency hopping information requires 2 bits, and resource offset value requires 4 bits.

[0147] The above method allows for more efficient use of currently available free bits for information indication.

[0148] In one possible implementation, the first terminal device may further determine information about the fourth resource (e.g., the location and size of the fourth resource). The first terminal device detects control information, such as PDCCH, on the fourth resource. Alternatively, the first terminal device transmits physical uplink control channel (PUCCH) information on the fourth resource.

[0149] In one implementation, the location of the fourth resource can be a fixed position within the first resource. For example, the starting position of the fourth resource is the lowest frequency position of the first resource. The bandwidth of the fourth resource can be equal to the bandwidth supported by the first terminal device. The first terminal device can determine the location of the fifth resource based on the control information detected on the fourth resource, and the first terminal device performs data information transmission on the fifth resource, such as PDSCH or PUSCH.

[0150] Optionally, after receiving or sending information from the fifth resource, the first terminal device can adjust the received signal frequency range back to the position for receiving control signals. For example, it can adjust the received signal frequency range back to the fourth resource. The fifth resource and the fourth resource do not overlap. The fifth resource is included within the first resource.

[0151] For example, such as Figure 7A Taking the fourth resource as an example, which is a more frequent resource (with a larger sequence number) among the second resources.

[0152] A1, the access network device can configure the location of the search space (SNS) in the first frequency within the second resource. The first frequency comprises a segment of frequency resources used for transmitting and receiving information. The first frequency includes N resource units ordered from largest to smallest, such as sub-carrier, RB, RE, REG, REG bundle, CCE, and carrier. For example, the first frequency may be the control resource set (SNS) configured by the network device. The first terminal device detects control information on the control resource set.

[0153] A2, the first terminal device detects the first control information on the first frequency, and the scheduling resource indicated by the first control information for the first terminal device is the second frequency. For example, the resource offset between the second frequency and the sixth resource is offset 1. The sixth resource can be the resource where the first terminal device's CORESET is located, or the resource where the first terminal device is located when receiving the control information, or a pre-configured resource, or a preset resource, or the second resource, or the third resource, or the first resource. The sixth resource may include the first frequency. The resource can be at least one of frequency domain resources, time domain resources, code domain resources, power resources, and spatial domain resources. The control information can be uplink scheduling information, uplink grant information, downlink scheduling information, or downlink grant information. The control information / scheduling grant information can be transmitted in the PDCCH, PDSCH, downlink broadcast channel (PBCH), or downlink paging channel.

[0154] A3, the first terminal device adjusts its signal reception range to a second frequency at time t2, such as according to at least one of offset 1, the first frequency, the third resource, and the second resource. The first terminal device receives PDSCH 1 and / or transmits PUSCH 1 on the second frequency. Here, time t2 can be predetermined, such as after a time period x following the detection of control information, or before a time period y before the start time of PDSCH 1 indicated in the control information, where x and y can be integers. Time t2 can also be signaled, such as instructing the first terminal device to complete frequency adjustment y time before the start time of PDSCH 1 / PUSCH 1 transmission. Frequency adjustment is also known as frequency tuning.

[0155] A4. After completing the transmission of PDSCH1 / PUSCH1, the first terminal device adjusts its signal reception range to the first frequency at time t3. The first terminal device monitors the PDCCH at the first frequency. Similar to t2, t3 can also be predefined or indicated; please refer to the relevant description of t2 for details, which will not be repeated here.

[0156] A5, the first terminal device detects second control information on a first frequency. This second control information indicates that the scheduling resource of the first terminal device is a third frequency, such as the resource offset between the third frequency and the sixth resource being offset 2. The sixth resource can be the resource where the first terminal device's CORESET is located, or the resource where the first terminal device is located when receiving the control information, or a pre-configured resource, or a preset resource, or a second resource, or a third resource, or a first resource. The sixth resource may include the third frequency. The resource can be at least one of frequency domain resources, time domain resources, code domain resources, power resources, and spatial domain resources. The control information can be uplink scheduling information, uplink grant information, downlink scheduling information, or downlink grant information. The control information / scheduling grant information can be transmitted in the PDCCH, PDSCH, PBCH, or downlink paging channel.

[0157] A6. At time t4, the first terminal device adjusts its signal reception range to a third frequency, such as adjusting to the third frequency based on at least one of offset 2, the first frequency, the third resource, and the second resource. The first terminal device receives PDSCH 2 and / or transmits PUSCH 2 on the third frequency. The time t4 can be predefined, such as a time period x after detecting control information, or a time period y before the start time of PDSCH 2 indicated in the control information, where x and y can be integers. The time t4 can also be signaled, such as instructing the first terminal device to complete frequency adjustment y time before the start time of PDSCH 2 / PUSCH 2 transmission. Frequency adjustment is also known as frequency tuning. Similar to t2, t4 can also be predefined or indicated; see the relevant description of t4 for details, which will not be repeated here.

[0158] For example, such as Figure 7B Taking the fourth resource as an example, which is a more frequent resource (with a larger sequence number) among the second resources.

[0159] B1. Access network devices can configure the location of the CORESET / Search space (SS) at the first frequency in the second resource. For details, please refer to the relevant description in A1 above; it will not be repeated here.

[0160] B2, the first terminal device detects the first PDCCH / PDSCH on the first frequency, and the resource indicated by the first PDCCH / PDSCH for the first terminal device to transmit uplink control information is the second frequency. For details, please refer to the relevant description in A2 above, which will not be repeated here. Alternatively, the first terminal device receives first data information on the first frequency, and the resource for the first terminal device to transmit uplink control information is the second frequency.

[0161] B3, the first terminal device adjusts its signal reception range to the second frequency at time t2, such as based on at least one of offset 1, the first frequency, the third resource, and the second resource. The first terminal device transmits PUCCH 1 on the second frequency. For details, please refer to the relevant description in A3 above, which will not be repeated here.

[0162] B4. After completing the PUCCH transmission, the first terminal device adjusts its signal reception range to the first frequency at time t3. The first terminal device monitors the PDCCH at the first frequency. Similar to t2, t3 can also be predefined or indicated; please refer to the relevant description of t2 for details, which will not be repeated here.

[0163] B5, the first terminal device detects or receives the second PDCCH or second PDSCH on the first frequency. This second PDCCH / PDSCH indicates that the scheduling resource for the first terminal device is the third frequency. For details, please refer to the relevant description in A5 above; it will not be repeated here.

[0164] B6, at time t4, the first terminal device adjusts its signal reception range to the third frequency, such as based on at least one of offset 2, the first frequency, the third resource, and the second resource. The first terminal device transmits PUCCH 2 on the third frequency. For details, please refer to the relevant description in A6 above; it will not be repeated here.

[0165] In another implementation, the first terminal device may determine the information of the fourth resource (e.g., the location and length of the fourth resource) based on the first information (e.g., the location and / or length of the second resource).

[0166] The first terminal device can determine the location of the fifth resource based on the control information detected in the fourth resource. The first terminal device then detects data information, such as PDSCH or PUSCH, on the fifth resource. The specific method is similar to the method of determining the data information resource based on control information in the previous implementation, and will not be described in detail here.

[0167] Optionally, after receiving the data signal, the first terminal device may not change the frequency range of the received signal. Instead, it monitors for control information within the frequency range of the received data signal until it receives control information, and then changes the frequency range of the received signal according to the control information.

[0168] For example, such as Figure 8A Taking the fourth resource as an example, which is a more frequent resource (with a larger sequence number) among the second resources.

[0169] C1, the access network device can configure the SS position in the first frequency of the second resource. The first frequency includes a segment of frequency resources used for transmitting and receiving information. The first frequency includes N resource units whose sequence numbers are sorted from largest to smallest, such as sub-carrier, RB, RE, REG, REG bundle, CCE, carrier, etc. For example, the first frequency may be the CORESET configured by the network device. The first terminal device detects control information on the control resource set.

[0170] C2, the first terminal device detects the first control information on the first frequency, and the scheduling resource indicated by the first control information for the first terminal device is the second frequency. For example, the resource offset between the second frequency and the sixth resource is offset 1. The sixth resource can be the resource where the first terminal device's CORESET is located, or the resource where the first terminal device is located when receiving the control information, or a pre-configured resource, or a preset resource, or the second resource, or the third resource, or the first resource. The sixth resource may include the first frequency. The resource can be at least one of frequency domain resources, time domain resources, code domain resources, power resources, and spatial domain resources. The control information can be uplink scheduling information, uplink grant information, downlink scheduling information, or downlink grant information. The control information / scheduling grant information can be transmitted in the downlink control channel PDCCH, the downlink data channel PDSCH, the downlink broadcast channel PBCH, or the downlink paging channel.

[0171] C3, the first terminal device adjusts its signal reception range to the second frequency at time t2, such as according to at least one of offset 1, the first frequency, the third resource, and the second resource. The first terminal device receives PDSCH 1 and / or transmits PUSCH 1 on the second frequency. The time t2 can be predetermined, such as after a time period x following the detection of control information, or before a time period y before the start time of PDSCH 1 indicated in the control information, where x and y can be integers.

[0182] Example 2: See Figure 9 This is a flowchart illustrating a resource indication method provided in this application. The method includes:

[0183] S901, the access network device determines fourth information, which indicates the location information and resource size information of the third resource within the first resource. The number of resources included in the first resource is greater than the number of resources that the first terminal device can support. The number of resources included in the third resource is less than or equal to the number of resources that the first terminal device can support.

[0184] S902, the access network device sends fourth information to the first terminal device. Correspondingly, the first terminal device receives the fourth information sent by the access network device.

[0185] S903, the first terminal device determines the first resource.

[0186] It should be noted that there is no strict order between steps S902 and S903. Step S902 can be executed first and then step S903, or step S903 can be executed first and then step S902, or steps S902 and S903 can be executed simultaneously.

[0187] S904, the first terminal device transmits information on the third resource.

[0188] For example, the information transmitted by the first terminal device on the third resource may be control information, data information, paging information, random access information, random access response information, etc. Control information may include uplink control information and downlink control information. Data information may include uplink data information and downlink data information.

[0189] In this embodiment, the access network device can configure the scheduling resources of the first terminal device at any location within a broadband resource, so that the scheduling resources of the first terminal device are not limited to the area supported by the capability or the limited resources configured. In this way, the scheduling resources of different first terminal devices can be distributed at different locations within the broadband resource, thereby avoiding service congestion and achieving better load balancing.

[0190] It should be noted that, in the embodiments of this application, the size of the first resource and the third resource can be understood as a time domain range, a frequency domain range, etc., or as the number of resources included.

[0191] In this embodiment, the first and third resources can be time-domain resources, frequency-domain resources, spatial-domain resources, code-domain resources, power resources, etc. For example, the resource units of time-domain resources can be radio frames, subframes, half-frames, time slots, symbols, etc. The resource units of frequency-domain resources can be sub-carriers, resource blocks (RBs), resource elements (REs), resource element groups (REGs), REG bundles, control channel elements (CCEs), and carriers. For example, if the bandwidth is 20MHz and the subcarrier spacing is 15kHz, the number of resource blocks included can be 106 RBs.

[0192] In one exemplary description, the size of resources that the first terminal device can support (or allocate) can be understood as the number of resource blocks included in the supported bandwidth. The number of resource blocks included in the supported bandwidth can be the maximum number of frequency domain resource blocks that the first terminal device can occupy when transmitting and / or receiving, such as the maximum bandwidth of the signal the first terminal device can receive, and / or the maximum bandwidth of the signal the first terminal device can transmit. For example, if the supported bandwidth is 20MHz and the subcarrier spacing is 15kHz, the supported number of resource blocks is 106 RBs.

[0193] The following example uses the first resource as a frequency domain resource to illustrate the first resource.

[0194] In one implementation, the first resource can be the initial BWP of the first terminal device. Optionally, the first terminal device can obtain information about the first resource through system messages broadcast by the access network device. Optionally, the first resource can be the initial BWP of the second terminal device. The second terminal device has higher capabilities than the first terminal device. For example, the second terminal device supports a greater bandwidth than the first terminal device, the second terminal device has a shorter data processing time than the first terminal device, or the second terminal device supports a greater maximum number of transmission layers than the first terminal device.

[0195] In another implementation, the first resource can be a carrier wave operated by the access network device. In this implementation, the first resource can be a transmission resource with a predefined resource location and bandwidth. Optionally, the first terminal device can obtain information about the first resource before joining the network.

[0196] In another implementation, the first resource can also be notified by the access network device via signaling. For example, the access network device can indicate a frequency range for user use via system messages or broadcast messages. The first terminal device obtains information about the first resource by receiving system messages or broadcast messages.

[0197] In one exemplary embodiment, the fourth information may indicate the starting position S and length L of the third resource within the first resource.

[0198] S can be greater than the size of the resources supported by the first terminal device, and L can be less than or equal to the first value. For example, if the first resource includes N resources... L The first value is N r Then the range of values ​​for S can be [0, N]. L -1], the range of L can be [1, N] r ], and S+L≤N L Wherein, the first value is greater than or equal to the number of resources included in the third resource. The first value is less than or equal to the number of resources that the first terminal device can support. Alternatively, the first value is a value pre-configured by the access network device.

[0199] In some embodiments, the first value may be determined based on the capabilities of the first terminal device or configured by the access network device. Wherein, the first value determined based on the capabilities of the first terminal device may refer to the maximum value of resources that the first terminal device can support for receiving and / or transmitting signals. Where the first value is configured by the access network device, it may refer to the size of resources for subsequent receiving and / or transmitting signals that the access network device can instruct the first terminal device to do so via signaling, or the size of resources that the access network device schedules for the first terminal device to receive and / or transmit signals.

[0200] Optionally, the number of bits in the fourth information can be determined based on the size of the first resource and the first value.

[0201] For example, the possible values ​​for S are N. L One, requiring log2(N) L ×(N L +1) / 2) bits are used for indication. The value range of S is within the first resource range. There are Nr selectable values ​​for L, requiring log2(N r ×(N r +1) / 2) bits are used for indication. The value of L is less than or equal to the maximum bandwidth supported by the first terminal device. Then the fourth information may include [log2(N L ×(N L +1) / 2)+log2(N r ×(N r +1) / 2) bits.

[0202] For example, the number of bits for the fourth information can be log2 (state value), where the state value of the fourth information can be as shown in Table 6.

[0203] Table 6

[0204]

[0205] In some embodiments, the starting point location S can be the BWP / carrier bandwidth N configured by the access network device. L Any value within the range. For example, the initial BWP. However, the length L needs to be limited to Nr based on the first value. For example, the length L is the maximum number of RBs that the first terminal device can support in transmission. That is, the range of values ​​for the starting point S and the length L are not the same.

[0206] To further reduce overhead, the granularity of S can be configured as an integer multiple of RB, such as 2 / 4 / 8 / 16, etc. For example, with a granularity of 4, assuming the bandwidth of the first resource is 50M, the first value is the number of RBs included in a 20M bandwidth, i.e., N. L =270, N r =106, then the number of bits for the fourth information is 13 bits.

[0207] In some embodiments, when the first terminal device satisfies the first characteristic, the control information provided in Embodiment 2 of this application includes fourth information. When the first terminal device satisfies the second characteristic, it can obtain existing control information, namely third information. The third information carries at least one of the following: the location information of the third resource in the first resource, and frequency hopping information. For example, the frequency hopping information may include at least one of frequency hopping indication and frequency hopping offset value, wherein the frequency hopping indication is used to indicate whether frequency hopping is required.

[0208] For example, the first characteristic is that the bandwidth (BWP) of the first terminal device is greater than or equal to the bandwidth that the first terminal device can support. For example, the BWP is the initial BWP.

[0209] The second characteristic is that the bandwidth (BWP) of the first terminal device is less than or equal to the bandwidth that the first terminal device can support. For example, the BWP is the initial BWP.

[0210] In other embodiments, the first terminal device can support acquiring both fourth and third information; that is, the acquired UL grant information may include both fourth and third information. For example, when the initial bandwidth of the first terminal device is small (e.g., 5M / 10Mhz), or when it operates at a high frequency (e.g., FR2), or when its SCS is large (e.g., 60 / 120 / 240kHz), the acquired UL grant information may include both fourth and third information.

[0211] The above method allows for more efficient use of currently available free bits for information indication.

[0212] In one possible implementation, the first terminal device can further determine information about the fourth resource (e.g., the location and size of the fourth resource). The first terminal device detects control information, such as PDCCH or physical uplink control channel (PUCCH), on the fourth resource. Specifically, the method for determining the fourth resource can be found in the relevant description of Embodiment 1 above, and will not be repeated here.

[0213] In one implementation, the location of the fourth resource can be a fixed position within the first resource. For example, the starting position of the fourth resource is the lowest frequency position of the first resource. The bandwidth of the fourth resource can be equal to the bandwidth supported by the first terminal device. The first terminal device can determine the location of the fifth resource based on the control information detected on the fourth resource, and the first terminal device detects data information, such as PDSCH or PUSCH, on the fifth resource.

[0214] Optionally, after receiving or sending information from the fifth resource, the first terminal device can adjust the received signal frequency range back to the control signal receiving position, that is, adjust the received signal frequency range back to the fourth resource. The fifth resource and the fourth resource do not overlap; the fifth resource is included within the first resource.

[0215] For details, please refer to Example 1. Figure 7A or Figure 7B Related descriptions.

[0216] In another implementation, the first terminal device may determine the information of the fourth resource (e.g., the location and length of the fourth resource) based on the first information (e.g., the location and / or length of the second resource).

[0217] The first terminal device can determine the location of the fifth resource based on the control information detected in the fourth resource. The first terminal device detects data information, such as PDSCH or PUSCH, on the fifth resource.

[0218] Optionally, after receiving the data signal, the first terminal device may not change the frequency range of the received signal. It can receive control information within the frequency range of the received data signal until it receives control information, at which point it changes the frequency range of the received signal according to the control information received.

[0219] For details, please refer to Example 1. Figure 8A or Figure 8B Related descriptions.

[0228] For example, the transceiver unit 1001 receives the fourth information through random access response information.
