Background
With the development of communications, the international telecommunications union (international telecommunication union, ITU) defines a mass machine type communication (massive machine type communications, mctc) standard. Currently, a User Equipment (UE) performing an mctc service is referred to as a reduced capability (reduced capability, REDCAP) UE in the standard, i.e., a UE with low complexity or low capability, and the UE may have a lower complexity in terms of bandwidth, power consumption, number of antennas, etc. than other UEs, such as a narrower occupied bandwidth, lower power consumption, fewer number of antennas, etc. Such UEs may also be referred to as lightweight end devices (NRL).
Because the bandwidth occupied by the REDCAP UE is relatively narrow, if the number of users of the REDCAP UE is relatively large, the REDCAP UE is concentrated in the relatively narrow bandwidth, so that the plurality of REDCAP UEs are easy to compete for the bandwidth, and further traffic blocking is caused.

Currently, random access for UEs includes both contention-based and non-contention-based.
As shown in fig. 2, the contention-based random access procedure of the 4-step random access includes:
s201, the UE sends a random access preamble (random access preamble), which may also be referred to as a first message (Msg 1), to the access network device. The random access preamble is used to inform the access network device of a random access request and enable the access network device to estimate the transmission delay between the access network device and the UE, so that the access network device calibrates the uplink timing (uplink timing) and informs the UE of the calibration information via a timing advance command (timing advance command).
S202, the access network device sends a random access response (random access response, RAR), which may also be referred to as a second message (Msg 2), to the UE after detecting the random access preamble. The random access response may include, but is not limited to, a sequence number including the random access preamble received in S201, a timing advance instruction, uplink resource allocation information, a cell radio network temporary identifier, and the like.
And S203, the UE receives a random access response, and 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 equipment in S201, the UE considers that the random access response is the random access response aiming at the UE, namely, the UE receives the random access response of the UE. After receiving the random access response, the UE transmits an uplink message on an uplink channel resource indicated by the random access response, for example, transmits a physical uplink shared channel (physical uplink shared channel, PUSCH), also referred to as a third message (Msg 3), in Msg 3. Wherein Msg3 may carry a unique user identification.
S204, the access network equipment receives the uplink message of the UE and returns a conflict resolution message, also called a fourth message (Msg 4), to the accessed UE. The access network device will carry the unique user identification in Msg3 in the collision resolution message to designate the successfully accessed UE, while other UEs that are not successfully accessed will re-initiate random access.
In the contention-based procedure, the access network device cannot acquire the identification information of the UE before Msg 3.
As shown in fig. 3, the non-contention based random access procedure includes:
S301, the access network device allocates random access preamble to the UE.
S302, the UE sends a dedicated random access preamble to the access network device.
S303, the access network equipment sends RAR to the UE.
In the non-contention based random access procedure, the access network device may acquire the identification information of the UE before transmitting the RAR message. The access network device may obtain information of the UE according to the identification information of the UE, such as which type of terminal the UE belongs to, e.g. an existing terminal (ebb terminal), a remote access point terminal, and a legacy terminal.
The RAR includes scheduling (UL grant) information of uplink transmission by the access network device. Wherein the frequency domain resource allocation indication field (frequency domain resource allocation) of 14bits is included. The frequency domain resource allocation indication field is used to indicate frequency domain resource allocation (frequency domain resource allocation, FDRA) information, i.e. a starting resource position and a length of the uplink transmission frequency domain resource. As shown in table 1.
TABLE 1
The position of the uplink frequency domain resource is determined by a joint code value indicating the starting resource position and length, if the number of uplink allocatable resources, i.e. the number of physical resource blocks (physical resource block, PRB) of the initial uplink bandwidth region, is The status that the FDRA needs to indicate isThe number of bits required for FDRA isIf the allocable resource bandwidth is less than or equal to 180RBs, the NR protocol prescribes that the frequency domain resource indication domain is shortened to be of length according to the DCI format 0_0 mode The lower bits (least significant bits, LSB) thereof are reserved.
The UL grant further includes a 1bit frequency hopping identifier for indicating whether the uplink transmission is frequency hopped or not. If frequency hopping is performed, the most significant bit (most significant bits, MSB) is 1bit or 2bits, i.e. N, according to the system bandwidth UL,hop Indicating the magnitude of the offset value of the frequency domain location of the second hop relative to the first hop. As shown in Table 2, if the allocatable resource bandwidthWhen N UL,hop 1bit if the allocatable resource bandwidthWhen N UL,hop Is 2 bits.
TABLE 2
The following illustrates different subcarrier spacing (SCS), and the number of bits required to indicate the location of the uplink transmission frequency domain resource under different bandwidths, wherein the low frequency band (frequency range 1, fr 1) may be shown in table 3, and the high frequency band (frequency range 2, fr 1) may be shown in table 4.
TABLE 3 Table 3
TABLE 4 Table 4
According to tables 3 and 4 above, under some bandwidth configurations (e.g., table 3 bandwidth less than 20MHz or table 4100MHz bandwidth), the number of bits required to indicate the location of the uplink transmission frequency domain resources is less than 14 bits.
Take the case of the first terminal device in FR1 as an example. If the maximum bandwidth supported by the first terminal device is below 20M, the corresponding maximum RB number is approximately less than or equal to 106. The number of bits required for indicating the position of the uplink transmission frequency domain resource is at most 13bits, and the frequency domain resource indication domain can be unused at least for the rest 1 bit. For small bandwidths (e.g., 5M/10 Mhz), or for the case of a larger high frequency (FR 2) SCS (60/120/240 kHz). At this time, there are more idle bits. For example, when scs=60 kHz, bandwidth=20 MHz includes 24RB, and frequency domain resource indicates that 9bits are needed. The frequency hopping information needs 2bits and the resource offset value is 4bits. The first terminal device may be a low capability terminal device, such as a REDCAP UE or the like.
Because the supportable bandwidth of the first type of terminal equipment is narrower, the first type of terminal equipment is concentrated in the narrower bandwidth under the condition that the number of users of the first type of terminal equipment is relatively large, and service blocking and transmission/access time delay are increased. The first type of terminal device may be a low capability terminal device, such as a REDCAP UE.
Based on this, the embodiment of the application provides a resource indication method and device, which are used for solving the problem that REDCAP UE is easy to cause service blocking. The method and the device are based on the same inventive concept, and because the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repetition is not repeated.
In this embodiment of the present application, the location of the second resource in the first resource may be indicated in the RAR UL grant, where the size of the first resource is greater than the size of the resource supportable by the first terminal device. The second resource comprises a number of resources that is less than or equal to the number of resources that can be supported by the first terminal device. As shown in fig. 4, the left side is the first resource and the right side is the second resource, the first resource being aligned with the upper boundary of the second resource. The available resource range (such as the second resource) of the first terminal equipment is not limited to the capability supportable (the capability of the first terminal equipment is lower) or configured in a narrower bandwidth, so that traffic blocking can be avoided, and load balancing is better performed. The first resource may be an initial BWP resource of a broadcast message notification. For example, the first resource may also be an initial BWP resource of the second terminal device, where the bandwidth supported by the second terminal device is larger than the bandwidth supported by the first terminal device. The bandwidth supported by the first terminal device may be understood as the maximum bandwidth supported by the first terminal device. As another example, the first resource may also be a frequency domain resource, such as a carrier, where the access network device operates.
It should be understood that in embodiments of the present application, "at least one" means one or more, and "a plurality" means two or more. "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a alone, a and B together, and B alone, wherein A, B may be singular or plural. The character "/" generally indicates that the context-dependent object is an "or" relationship. "at least one (item) below" or the like, refers to any combination of these items, including any combination of single item(s) or plural items(s). For example, at least one (one) of a, b or c may represent: a, b, c, a and b, a and c, b and c, or a, b and c, wherein a, b and c can be single or multiple.
In addition, it should be understood that in the description of the present application, the words "first," "second," and the like are used merely for distinguishing between the descriptions and not for indicating or implying any relative importance, nor order of indication or implying any particular order.
The method provided in the embodiments of the present application is specifically described below with reference to the accompanying drawings.
Embodiment one: referring to fig. 5, a flow chart of a resource indication method provided in the present application is shown. The method comprises the following steps:
s501, the access network equipment determines first information and second information, wherein the first information indicates the position of second resources in first resources, and the number of the resources included in the first resources is larger than that of the resources supportable by the first terminal equipment; the second resource comprises the resources with the quantity smaller than or equal to the quantity of the resources which can be supported by the first terminal equipment; the second information indicates a location of a third resource in the second resource, the second resource including a number of resources greater than or equal to a number of resources included by the third resource. For example, the content indicated by the second information may be as shown in fig. 6.
By way of example, the first terminal device may be a low capability terminal device, such as a REDCAP UE or the like.
The sizes of the first resource, the second resource, and the third resource may be understood as a time domain range, a frequency domain range, etc. of the resources, and may also be understood as the number of the included resources.
In this embodiment of the present application, the first resource, the second resource, and the third resource may be a time domain resource, a frequency domain resource, a space domain resource, a code domain resource, a power resource, and so on. Illustratively, the resource units of the time domain resources may be radio frames, subframes, fields, slots, mini-slots, symbols, and the like. The resource unit of the frequency domain resource may be a subcarrier (sub-carrier), a Resource Block (RB), a Resource Element (RE), a Resource Element Group (REG), a REG bundle (REG bundle), a control channel element (control channel element, CCE), a carrier. For example, if the bandwidth is 20MHz, the number of included resource blocks may be 106 RBs when the subcarrier spacing is 15 kHz.
In an exemplary illustration, the size of the resources that the first terminal device can support (or can allocate) can be understood as the number of resource blocks that the supported bandwidth includes. The supported bandwidth may include a number of resource blocks that may be the maximum number of frequency domain resource blocks that the first terminal device is capable of occupying when transmitting and/or receiving. E.g. the maximum bandwidth the first terminal device can receive signals, and/or the maximum bandwidth the first terminal device can transmit signals, etc. For example, the supported bandwidth is a 20MHz bandwidth, and the number of supported resource blocks is 106 RBs when the subcarrier spacing is 15 kHz.
The first resource is exemplified as a frequency domain resource in the following.
In one implementation, the first terminal device may obtain the information of the first resource through a system message broadcasted by the access network device. The first resource may also be an initial BWP of the second terminal device. For example, the UE capability of the second terminal device is higher than that of the first terminal device. The capability includes at least one of supportable bandwidth, speed of processing data, number of antennas supported, maximum modulation coding scheme supported.
In another implementation, the first resource may be a carrier on which the access network device operates. In this implementation, the first resource may be a predefined good resource location and bandwidth. Optionally, the first terminal device may acquire information of the first resource before entering the network.
In yet another implementation, the first resource may also be signaled by the access network device. For example, the access network device may instruct the user to use a range of frequencies via a system message or a broadcast message. The first terminal device obtains the information of the first resource by receiving the system message or the broadcast message.
In one implementation, the size of the second resource may be the size of a resource that the first terminal device may support (or may allocate).
In some embodiments, the second resource may be sized according to the capabilities of the first terminal device or may be configured by the access network device. The size of the second resource is determined according to the capability of the first terminal device, which may mean that the size of the second resource is the maximum value of the resources that can be supported by the first terminal device for receiving and/or signaling. The size of the second resource is configured by the access network device, and may refer to a size range of the access network device indicating the first terminal device's receiving and/or signaling resources through signaling, or a size range of the access network device scheduling the first terminal device's receiving and/or signaling resources.
Taking the second resource as a frequency domain resource as an example, the frequency domain range of the second resource may be determined according to the capability of the first terminal device, or may be configured by the access network device. The frequency domain range of the second resource is determined according to the capability of the first terminal device, which may mean that the frequency domain range of the second resource is the maximum bandwidth or the maximum number of resources that can be supported by the first terminal device for receiving and/or signaling. The frequency domain range of the second resource is configured by the access network device, which may refer to the access network device indicating the maximum bandwidth or the maximum number of resources of the first terminal device for receiving and/or signaling through signaling, or the access network device scheduling the maximum bandwidth or the maximum number of resources of the first terminal device for receiving and/or signaling.
S502, the access network equipment sends first information and second information to the first terminal equipment. Correspondingly, the first terminal device receives the second information.
S503, the first terminal equipment determines a first resource.
It should be noted that, the step S502 and the step S503 are not strictly sequential, and the step S502 may be performed first and then the step S503 may be performed, the step S503 may be performed first and then the step S502 may be performed, or the step S502 and the step S503 may be performed simultaneously.
S504, the first terminal equipment transmits information on the third resource. For example, the first terminal device performs information transmission on the third resource. Correspondingly, the access network equipment receives the information on the third resource. For example, the first terminal device receives information on the third resource. Correspondingly, the access network equipment sends information on the third resource.
For example, the information transmitted by the first terminal device on the third resource may be control information, data information, paging information, random access corresponding information, broadcast information, and the like. The control information may include uplink control information and downlink control information. The data information may include uplink data information and downlink data information.
In this embodiment of the present application, the access network device may configure the second resource at any position of the first resource, where the size of the first resource is greater than the size of the resource that can be supported by the first terminal device. The size of the second resource does not exceed the size of the resources supportable by the first terminal device. Such that the second resource is no longer fixed in a fixed location, so that the scheduled resources of the first terminal device may not be limited to areas or configured fewer resources that can be supported by the capabilities. In this way, the scheduling resources of different first terminal devices can be distributed at different positions of the broadband resources, so that traffic blocking can be avoided, and load balancing can be performed better.
In one exemplary illustration, the second information may be frequency domain resource allocation in the RAR. It should be noted that, the number of bits of frequency domain resource allocation is fixed to 14 bits at present, but in the embodiment of the present application, the number of bits of the second information may be determined according to the number of resources of the first terminal device or the size of the second resource. For example, the number of bits of the second information may satisfy the followingThe formula:wherein N is the number of resources of the first terminal device for transmitting information, which may be understood as the number of resources that may be allocated for uplink transmission of the first terminal device, or the number of PRBs of 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.
In one implementation, the second information may be available through the current PUSCH frequency domain resource allocationThe indication is made by a number of bits. The random access response also includes first information. The first information and the second information require a number of bits less than or equal to 14 bits. Or, the number of bits required by the first information and the second information is smaller than or equal to the number of bits included in the frequency domain resource allocation indication domain of the second first terminal device. By the implementation mode, the signaling overhead can be reduced.
In one implementation, the first information and/or the second information is transmitted in random access response information (RAR). For example, the access network device may send the first information and the second information to the first terminal device through the RAR.
For example, the random access response information may be at least one of response information of a random access physical downlink control channel (physical downlink control channel, PDCCH), response information of a random access physical downlink shared channel (physical downlink shared channel, PDSCH), and the like, and the random access response information includes uplink grant information.
In one exemplary illustration, the information included in the UL grant in the RAR may be as shown in table 5.
TABLE 5
Optionally, the UL grant information may further include other information, such as frequency hopping identifier, MCS, TPC command for PUSCH, etc., and specifically refer to table 1 above.
In one implementation, the number of bits included in the grant information in the RAR is less than or equal to the number of bits included in the RAR grant information in the forward version. For example, the forward version is the NR R15 version.
In one implementation, the number of bits included in the authorization information in the RAR is less than or equal to 28 bits.
In one implementation, the frequency resource allocation indication field in the grant information in the RAR includes less than 14 bits. And, the authorization information in the RAR includes first information, where the first information is location information indicating that the second resource is in the first resource.
The resource indication method in the embodiment of the present application is described below by taking the third resource as an uplink scheduling resource of the first terminal device, the second resource as a bandwidth supportable by the first terminal device, and the bandwidth of the first resource is greater than that of the second resource as an example.
If the number of required frequency domain resource allocation indication bits is smaller than the number of existing FDRA bits because the bandwidth supported by the UE is small according to the number of existing FDRA bits, it may result in the PUSCH frequency domain resource allocation domain having idle bits. The idle bit may be used in embodiments of the present application to indicate a frequency domain offset value (i.e., first information) of the second resource within the first resource.
In one exemplary illustration, the first information may indicate a starting location S1 of the second resource. The second information may indicate an offset value S2 of the starting position of the third resource with respect to the starting position of the second resource and a length L of the third resource.
Wherein S1 may be an offset value of a minimum RB index (index) of an allocable resource (i.e., a second resource) of the first terminal device with respect to a reference point. In one example, the first resource may be an initial bandwidth area resource configured by the access network device for the first terminal device, and the reference point may be a minimum RB index of allocable resources of the initial bandwidth area resource. In another example, the first resource may be a frequency domain range indicated by the access network device and the reference point may be a resource location indicated by the access network device.
The first information may indicate S1. Where S1 may be a preconfigured value (e.g., integer multiple of RB, 10M, 20M, BWP/4, BWP/2, etc.). Alternatively, the first information may include an indication value, and S1 may be a value calculated according to a preset rule based on the indication value. For example, S1 may be equal to a multiple of the initial bandwidth of the first terminal device, which is the indicated value carried by the first information. For example, S1 may be equal to the indicated value carried by the first information. For example, S1 may be equal to a multiple of the bandwidth supportable by the first terminal device by the indicated value carried by the first information. Wherein S1 may indicate an offset value of the start position of the second resource with respect to the start position of the first resource with 3 bits. The offset value may be a predefined value, or a value that the access network device indicates in advance by signaling, or a value calculated in a predefined manner for the indication carried by the first information.
Illustratively, the offset value may be determined in the following predefined manner: the offset value may be determined according to the number of RBs included in the first resource and the number of candidate values of the offset value. For example, S1 is equal to the number of candidates for the W/offset value. For example, W is the number of RBs included in an initial BWP resource (e.g., a first resource) configured by the access network device. For example, W is 270. The number of candidates for the offset value is 8. The offset value corresponding to the value i indicated by S1=w/8*i. Alternatively, an upper or lower rounding may be selected for the result to be an integer. Or, the offset value= (W-the first terminal device supports bandwidth)/(8-1) ×i. Or, offset value = (W-second resource size)/(8-1) ×i. The first terminal device supported bandwidth (e.g. the second resource or the preset value or the preconfigured value) may be determined according to the maximum bandwidth of the first terminal device capable of transmitting signals, or determined according to the maximum bandwidth of the first terminal device capable of receiving signals, or the maximum bandwidth that the access network device indicates the current transceiving support of the first terminal device, etc.
The second information may indicate S2 and L. For example, S2 and L are indicated with 11 bits.
In some embodiments, the first terminal device obtains UL grant information provided in the embodiments of the present application when the first characteristic is satisfied, including first information and second information. The first terminal device may acquire UL grant information defined by the existing protocol when the second characteristic is satisfied. Such as third information. The third information carries at least one of the following information: position 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, frequency hopping offset value. The frequency hopping indication information is used for indicating whether frequency hopping is performed or not. The first characteristic is that the BWP bandwidth is greater than or equal to a bandwidth supportable by the first terminal device. Illustratively, the BWP is an initial BWP. The second characteristic is that the BWP bandwidth is smaller than or equal to a bandwidth supportable by the first terminal device. If the first terminal device can support 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.
In other embodiments, the first terminal device may support acquiring both the first information and the second information, and may acquire the third information. That is, the acquired UL grant information may include both the first information and the second information, and may include the third information. For example, in the case where the initial bandwidth of the first terminal device is small (e.g., 5M/10 Mhz), or operating at a high frequency (e.g., FR 2), or SCS is large (e.g., 60/120/240 kHz), the acquired UL grant information may include both the first information and the second information, and may include the third information. For example, scs=60 kHz, bandwidth=20 MHz, including 24rb, fdra requires 9 bits, frequency hopping information requires 2 bits, and resource offset value 4 bits.
By the method, the current idle bits can be used for information indication more fully.
In a possible implementation manner, the first terminal device may further determine information of the fourth resource (for example, a location, a size, etc. of the fourth resource). The first terminal device detects control information, such as PDCCH, on the fourth resource. Or, the first terminal device transmits physical uplink control channel (physical uplink control channel, PUCCH) information on the fourth resource.
In one implementation, the location of the fourth resource may be a fixed location within the first resource. For example, the resource starting position of the fourth resource is the lowest position of the frequency domain of the first resource. The bandwidth of the fourth resource may be equal to the bandwidth supported by the first terminal device. The first terminal device may determine the location of the fifth resource according to the control information detected on the fourth resource, and the first terminal device performs data information transmission, such as PDSCH or PUSCH, on the fifth resource.
Optionally, after the first terminal device receives or transmits the information on the fifth resource, the frequency range of the received signal may be adjusted back to the receiving position of the control signal. Such as adjusting 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.

The first terminal device receives PDSCH1 and/or transmits PUSCH1 on the second frequency. The time t2 may be predetermined. Such as x time period after detection of the control information, or y time period before the PDSCH1 start time indicated in the control information, where x, y may be integers. the time t2 may also be signaled, e.g. to instruct the first terminal device to complete the frequency adjustment y time before the start time of the PDSCH1/PUSCH1 transmission.

Embodiment two: referring to fig. 9, a flow chart of a resource indication method provided in the present application is shown. The method comprises the following steps:
s901, the access network device determines fourth information, where the fourth information indicates location information and resource size information of the third resource in the first resource. The first resource comprises a number of resources greater than a number of resources supportable by the first terminal device. The third resource includes a number of resources less than or equal to a number of resources supportable by the first terminal device.
And S902, the access network equipment sends fourth information to the first terminal equipment. Correspondingly, the first terminal equipment receives fourth information sent by the access network equipment.
S903, the first terminal device determines the first resource.
It should be noted that, step S902 and step S903 are not strictly sequential, and step S902 may be performed first and then step S903 may be performed, step S903 may be performed first and then step S902 may be performed, or step S902 and step S903 may be performed simultaneously.
S904, the first terminal device transmits information on the third resource.
For example, the information transmitted by the first terminal device on the third resource may be control information, data information, paging information, random access corresponding information, and the like. The control information may include uplink control information and downlink control information. The data information may include uplink data information and downlink data information.
In the embodiment of the present application, the access network device may configure the scheduling resource of the first terminal device at any position of one wideband resource, so that the scheduling resource of the first terminal device may not be limited to the area that can be supported by the capability or the configured fewer resources. In this way, the scheduling resources of different first terminal devices can be distributed at different positions of the broadband resources, so that traffic blocking can be avoided, and load balancing can be performed better.
In this embodiment of the present application, the sizes of the first resource and the third resource may be understood as a time domain range, a frequency domain range, and so on. And may also be understood as the number of included resources.
In this embodiment of the present application, the first resource and the third resource may be a time domain resource, a frequency domain resource, a space domain resource, a code domain resource, a power resource, and so on. Illustratively, the resource units of the time domain resources may be radio frames, subframes, fields, slots, symbols, and the like. The resource unit of the frequency domain resource may be a subcarrier (sub-carrier), a Resource Block (RB), a Resource Element (RE), a Resource Element Group (REG), a REG bundle (REG bundle), a control channel element (control channel element, CCE), a carrier. For example, if the bandwidth is 20MHz, the number of included resource blocks may be 106 RBs when the subcarrier spacing is 15 kHz.
In an exemplary illustration, the size of the resources that the first terminal device can support (or can allocate) can be understood as the number of resource blocks that the supported bandwidth includes. The number of resource blocks included in the supported bandwidth may be the number of maximum frequency domain resource blocks that can be occupied by the first terminal device when transmitting and/or receiving, e.g., the maximum bandwidth that the first terminal device can receive a signal, and/or the maximum bandwidth that the first terminal device can transmit a signal, etc. For example, the supported bandwidth is a 20MHz bandwidth, and the number of supported resource blocks is 106 RBs when the subcarrier spacing is 15 kHz.
The first resource is exemplified as a frequency domain resource in the following.
In one implementation, the first resource may be an initial BWP of the first terminal device. Optionally, the first terminal device may acquire the information of the first resource through a system message broadcasted by the access network device. Alternatively, the first resource may be an initial BWP of the second terminal device. The second terminal device is a higher capability than the first terminal device. If the bandwidth supported by the second terminal device is greater than that of the first terminal device, the data processing time of the second terminal device is less than that of the first terminal device, or the maximum transmission layer number supported by the second terminal device is greater than that supported by the first terminal device.
In another implementation, the first resource may be a carrier on which the access network device operates. In this implementation, the first resource may be a transmission resource of a predefined good resource location and bandwidth. Optionally, the first terminal device may acquire information of the first resource before entering the network.
In yet another implementation, the first resource may also be signaled by the access network device, e.g., the access network device may indicate a frequency range for use by the user via a system message or a broadcast message. The first terminal device obtains the information of the first resource by receiving the system message or the broadcast message.
In one exemplary illustration, the fourth information may indicate a starting location S and a length L of the third resource in the first resource.
S may be greater than a size of a resource supported by the first terminal device, and L may 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 The value range of S can be [0, N L -1]L can be in the range of [1, N r ]S+L is less than or equal to N L . Wherein the first value is greater than or equal to the number of resources comprised by the third resource. The first value is less than or equal to the number of resources supportable by the first terminal device. Alternatively, the first value is a value preconfigured by the access network device.
In some embodiments, the first value may be determined according to a capability of the first terminal device, or may be configured by the access network device. Wherein the first value is determined according to the capability of the first terminal device, and may refer to the first value as the maximum value of the resources that the first terminal device can receive and/or signal. The first value is configured by the access network device and may refer to a size of a resource that the access network device may indicate to the first terminal device for subsequent receiving and/or signaling, or a size of a resource that the access network device schedules for the first terminal device to receive and/or signaling.
Alternatively, the number of bits of the fourth information may be determined according to the size of the first resource and the first value.
For example, the selectable value of S is N L The log is needed 2 (N L ×(N L +1)/2) bits. The value range of S is in the first resource range. The selectable value of L is Nr, log is needed 2 (N r ×(N r +1)/2) bits. The value range of L is smaller than or equal to the maximum bandwidth supported by the first terminal equipment. The fourth information may include log 2 (N L ×(N L +1)/2)+log 2 (N r ×(N r +1)/2)]Bits.
For another example, the number of bits of the fourth information may be log 2 (state value), wherein the state value of the fourth information may be as shown in table 6.
TABLE 6
In some embodiments, the location S of the starting point may be BWP/carrier bandwidth N configured by the access network device L Any value within the range. Such as initial BWP. But the length L needs to be limited to Nr according to a first value. If the length L is the maximum number of RBs supportable in the transmission of the first terminal device. I.e. the range of values for the starting point S and the length L is not the same.
To save overhead, further, the granularity of S may be configured to be an integer multiple of RB, such as 2/4/8/16, etc. For example, granularity is 4, assume that the bandwidth of the first resource is 5A bandwidth of 0M, a first value being the number of RBs comprised by the 20M bandwidth, i.e. N L =270,N r The fourth information has a bit number of 13 bits=106.
In some embodiments, the first terminal device obtains the control information provided in the second embodiment of the present application when the first characteristic is satisfied, and the control information includes fourth information. The first terminal device may acquire existing control information, i.e. third information, when the second characteristic is satisfied, where the third information carries at least one of the following information: the location information of the third resource in the first resource, frequency hopping information, and the frequency hopping information may include at least one of a frequency hopping indication and a frequency hopping offset value, wherein the frequency hopping indication indicates whether to frequency hop.
Illustratively, the first characteristic is that the first terminal device BWP is greater than or equal to a bandwidth supportable by the first terminal device. For example, the BWP is an initial BWP.
The second characteristic is that the first terminal device BWP is smaller than or equal to the bandwidth supportable by the first terminal device. For example, the BWP is an initial BWP.
In other embodiments, the first terminal device may support acquiring the fourth information and may acquire the third information, that is, the acquired UL grant information may include the fourth information and may include the third information. For example, in the case where the initial bandwidth of the first terminal device is small (e.g., 5M/10 Mhz), or operating at a high frequency (e.g., FR 2), or SCS is large (e.g., 60/120/240 kHz), the acquired UL grant information may include either the fourth information or the third information.
By the method, the current idle bits can be used for information indication more fully.
In a possible implementation manner, the first terminal device may further determine information of the fourth resource (for example, a location, a size, etc. of the fourth resource), and the first terminal device detects control information, such as a PDCCH or a physical uplink control channel (physical uplink control channel, PUCCH), on the fourth resource. Specifically, the determination manner of the fourth resource may refer to the related description of the first embodiment, and the description is not repeated here.
In one implementation, the location of the fourth resource may be a fixed location within the first resource. For example, the resource starting position of the fourth resource is the lowest position of the frequency domain of the first resource. The bandwidth of the fourth resource may be equal to the bandwidth supported by the first terminal device. The first terminal device may determine a location of a fifth resource according to the control information detected at the fourth resource, and the first terminal device detects data information, such as PDSCH or PUSCH, on the fifth resource.
Optionally, after the first terminal device receives or transmits information on the fifth resource, the first terminal device may adjust the frequency range of the received signal back to the receiving location of the control signal, i.e. adjust the frequency range of the received signal back to the fourth resource. The fifth resource and the fourth resource do not overlap, and the fifth resource is included in the first resource.
Reference may be made in particular to the description of embodiment one in relation to fig. 7A or fig. 7B.
