In the application, a UE receives first information, where the first information at least may include frequency domain resource allocation information and frequency hopping information; the frequency domain resource allocation information is used for indicating the length L of the allocated resource block and indicating the starting S of the allocated resource block; the frequency hopping information comprises one or more of frequency hopping identification information and frequency offset information; and the UE transmits the second information with the base station according to the first information.

Description

Information transmission method and communication device
Technical Field
The present application relates to the field of communications technologies, and in particular, to an information transmission method and a communications apparatus.
Background
With the development of communication technology, the International Telecommunications Union (ITU) defines a massive machine type communications (mtc) scenario. Currently, a terminal equipment (UE) performing an mtc service is referred to as a reduced capability (reduce capability) UE in the standard, that is, a low-complexity or low-capability UE, which may have a lower complexity than other UEs in terms of bandwidth, power consumption, number of antennas, and the like, for example, the UE occupies a narrower bandwidth, consumes less power, and has fewer antennas. This type of UE may also be referred to as a lightweight version (NR light, NRL) UE.
In a random access process of a red beacon UE, an uplink grant (UL grant) sent by a base station to the UE includes a Physical Uplink Shared Channel (PUSCH) frequency domain resource allocation domain (FDRA) with 13 bits, where the FDRA is used to indicate a position of a frequency domain resource where the UE sends the PUSCH, and further, the FDRA may indicate 2 13 Location of the =8192 frequency domain resources. But when PUSCH scheduled by UL grant requires frequency hopping transmission, the base station indicates the frequency offset by 2 bits in FDRA according to the system bandwidth of the red map UE. At this time, the number of positions of the frequency domain resource that the FDRA can indicate becomes small (from 2) 13 =8192 reduction to 2 11 = 2048), the flexibility of information transmission is reduced.

In a possible implementation manner, the frequency hopping information includes frequency offset information, the frequency offset information indicates frequency offset, and a value set of the frequency offset at least includes a frequency offset value 0 and a non-0 frequency offset value, and a value of the frequency offset has a corresponding relationship with the first parameter; or, the frequency hopping information includes frequency offset information, and the bit state of the frequency offset information includes a first state and a second state, where the frequency offset information corresponding to the first state indicates a frequency offset other than 0, the frequency offset information corresponding to the second state indicates disabling of frequency hopping transmission, and a first parameter corresponding to the frequency offset other than 0 is different from a first parameter corresponding to the disabling of frequency hopping transmission; or, the frequency hopping information includes frequency hopping identification information, the frequency hopping identification information indicates enabling or disabling of frequency hopping transmission, and a first parameter corresponding to enabling of frequency hopping transmission is different from a first parameter corresponding to disabling of frequency hopping transmission; wherein the first parameter includes at least one of a maximum L value and a maximum S value, the maximum L value being a maximum value of a length L of the resource block, and the maximum S value being a maximum value of a starting S of the resource block.
In one possible implementation, the first parameter corresponding to the non-0 frequency offset value is smaller than the first parameter corresponding to the frequency offset value 0; or, the first parameter corresponding to the frequency offset which is not 0 is smaller than the first parameter corresponding to the disabled frequency hopping transmission; or the first parameter corresponding to the enable frequency hopping transmission is smaller than the first parameter corresponding to the disable frequency hopping transmission.
In the above technical solution, the first information may instruct the terminal device to transmit the second information with the access network device in a frequency hopping manner (i.e., instruct the terminal device to enable frequency hopping), or instruct the terminal device to transmit the second information in a non-frequency hopping manner (i.e., instruct the terminal device to enable frequency hopping). In the process of transmitting the second information between the terminal equipment and the access network equipment, the maximum S value corresponding to the enabled frequency hopping is smaller than the maximum S value corresponding to the disabled frequency hopping, and/or the maximum L value corresponding to the enabled frequency hopping is smaller than the maximum L value corresponding to the disabled frequency hopping, so that the flexibility of frequency domain resource allocation is improved, and the flexibility of transmitting the second information between the terminal equipment and the access network equipment is improved.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.
Fig. 1 shows an architecture of a possible communication system to which the embodiment of the present application is applicable, which may include an access network device 101 and at least one terminal device (e.g., a terminal device 102 and a terminal device 103 in fig. 1). The terminal device is connected to the access network device 101 in a wireless manner. The terminal equipment may be fixed or mobile. Fig. 1 is a schematic diagram, and the communication system may further include other network devices, such as a wireless relay device and a wireless backhaul device, which are not shown in fig. 1. The embodiment of the present application does not limit the number of access network devices and terminal devices included in the mobile communication system, and the number shown in fig. 1 is only an example.
In the embodiment of the present application, the terminal device may be a terminal device in an internet of things (IoT) system, the IoT is an important component of future information technology development, and the main technical feature of the present application is to connect an article with a network through a communication technology, so as to implement an intelligent network with interconnected human-computer and interconnected objects. In the embodiment of the present application, the IoT technology may achieve massive connection, deep coverage, and power saving for the terminal device through, for example, a Narrowband (NB) technology. Illustratively, the terminal device may include sensors such as an intelligent printer, a train detector, a gas station, etc., and the main functions include collecting data (part of the terminal device), receiving control information and downlink data of the network device, sending electromagnetic waves, and transmitting uplink data to the network device.
The access network device 101 in the embodiment of the present application is an entity for transmitting or receiving signals on the network side. The access network device is one of network devices. The network devices include, but are not limited to: a base station (gNB), a Radio Network Controller (RNC), a Node B (Node B, NB), a Base Station Controller (BSC), a Base Transceiver Station (BTS), a home base station (e.g., home evolved NodeB, or home NodeB, HNB), a baseband unit (BBU), an Access Point (AP) in a wireless fidelity (WIFI) system, a wireless relay Node, a wireless backhaul Node, a transmission point (transmission and reception point, TRP, or transmission point, TP), etc., and may also be a network Node constituting the gNB or transmission point, such as a baseband unit (BBU), or a distributed unit (distributed unit, DU), etc.
In some deployments, the gNB may include a Centralized Unit (CU) and a DU. The gNB may also include a Radio Unit (RU). The CU implements part of the function of the gNB, and the DU implements part of the function of the gNB, for example, the CU implements Radio Resource Control (RRC) and Packet Data Convergence Protocol (PDCP) layers, and the DU implements Radio Link Control (RLC), medium Access Control (MAC) and Physical (PHY) layers. Since the information of the RRC layer eventually becomes or is converted from the information of the PHY layer, the higher layer signaling, such as RRC layer signaling or PDCP layer signaling, can also be considered to be transmitted by the DU or DU + RU under this architecture. It is to be understood that the network device may be a CU node, or a DU node, or a device including a CU node and a DU node. In addition, the CU may be divided into network devices in the access network RAN, or may be divided into network devices in the core network CN, which is not limited herein.
The access network equipment and the terminal equipment can be deployed on land, including indoor or outdoor, handheld or vehicle-mounted; can also be deployed on the water surface; it may also be deployed on airborne airplanes, balloons, and satellites. The embodiment of the application does not limit the application scenes of the access network equipment and the terminal equipment.
For convenience of description, the access network device is taken as a base station, and the terminal device is taken as a UE for illustration.
Currently, random access of a UE includes both contention-based and non-contention-based.
As shown in fig. 2, the contention based random access procedure includes:
in step 201, the ue sends a random access preamble (also referred to as a first message (Msg 1)) to the base station. The random access preamble is used for informing the base station of a random access request and enabling the base station to estimate a transmission delay between the base station and the UE, so that the base station calibrates uplink timing (uplink timing) and informs the UE of calibration information through a timing advance command (timing advance command).
In step 202, the base station sends a 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, the sequence number of the random access preamble received in step 201, a timing advance command, uplink resource allocation information, a cell radio network temporary identifier, and the like.
In step 203, 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 base station in step 201, the UE considers that the random access response is a random access response for the UE, that is, the UE receives the random access response of the UE. After receiving the random access response, the UE sends an uplink message, for example, sends a PUSCH, also referred to as a third message (Msg 3), on the uplink channel resource indicated by the random access response. Wherein, msg3 can carry a unique user identifier.
In step 204, the base station receives the uplink message of the UE and returns a conflict resolution message, also referred to as a fourth message (Msg 4), to the accessed UE. The base station carries the unique user identification in the Msg3 in the conflict resolution message to specify the UE with successful access, and other UE without successful access reinitiates random access.
As shown in fig. 3, the non-contention based random access procedure includes:
step 301, the base station allocates a random access preamble to the UE.
In step 302, the UE sends a dedicated random access preamble to the base station.
Step 303, the base station sends a random access response to the UE.
In the non-contention based random access procedure, the base station may acquire identification information of the UE before transmitting a random access response. The base station may obtain information of the UE according to the identification information of the UE, for example, which type of UE the UE belongs to, such as an existing UE (eMBB UE), a reccap UE, a legacy UE (legacy UE), and the like.
The random access response includes a UL grant, which may also be referred to as a RAR grant indication field (RAR grant field). The fields included in the UL grant may be as shown in table 1, and the UL grant includes a plurality of indication information and a bit number corresponding to each indication information. As shown in table 1, the UL grant includes information such as a frequency hopping flag (frequency hopping flag), a PUSCH Frequency Domain Resource Allocation (FDRA), a PUSCH time domain resource indication (TDRA), a Modulation and Coding Scheme (MCS), a PUSCH transmission power control command (TPC command for PUSCH), and a channel state information request (CSI request). The channel state information request is a reserved (reserved) field, i.e., the field is not used to indicate the channel state information request or other information.

Uplink grant Number of bits
Frequency hopping identification information 1
PUSCH frequency domain resource allocation information 14
PUSCH time domain resource allocation information 4
MCS 4
PUSCH transmit power control commands 3
Channel state information request 1
In the UL grant, FDRA is used forAnd indicating the position of the PUSCH frequency domain resource scheduled by the UL grant. FDRA can occupy 14 bits and can indicate 2 at most 14 The seed status, i.e. can indicate 2 14 The location of the frequency domain resource.
When the FDRA indicates the position of the PUSCH frequency domain resource, the position may be specifically determined by indicating a Resource Block (RB) length L and a resource block start S of the PUSCH frequency domain resource, where the resource block length L may be understood as the number of resource blocks, for example, the resource block length is 10, and may indicate that the PUSCH frequency domain resource includes 10 resource blocks. The resource block start S may be understood as a starting sequence number, or a starting index, or a sequence number of a starting resource block.
If the number of the resource blocks which can be allocated by the uplink transmission is as
Figure BDA0003058722270000071
(i.e., a partial bandwidth part (BWP) size), the FDRA needs to indicate a state of
Figure BDA0003058722270000072
And (4) respectively. FDRA requires a number of bits of
Figure BDA0003058722270000073
For example, when the bandwidth of BWP is 106RB, the resource block start S may be any number from 0 to 105, and the resource block length L may be any number from 1 to 106. Specifically, when the starting S of the resource block is 0, the length L of the resource block is any one of 1 to 106; when the starting S of the resource block is 1, the length L of the resource block is any one of 1-105, \ 8230 \ when the starting S of the resource block is 105, the length L of the resource block is 1. Thus, when the bandwidth of BWP is 106RB, the state that FDRA needs to indicate is 106 x (106 + 1)/2, and the bit number needed by FDRA is 13.
The NR protocol provides for truncating the FDRA to a length if the allocable resource bandwidth is less than or equal to 180RB

And a low bit (LSB) is reserved therein. Such asIn the above example, 13 bits of the lower bits in the FDRA may be used to indicate the position of the frequency domain resource.
Further, when the base station indicates the starting S and the length L of the resource block, it specifically indicates a Resource Identifier Value (RIV) obtained by encoding according to the starting S and the length L of the resource block. The numbering formula for RIV is as follows:
Figure BDA0003058722270000081
when the base station indicates the frequency domain resource allocation, the indication is the RIV, and correspondingly, after receiving the RIV, the UE can obtain the starting S of the resource block and the length L of the resource block by reverse-deducing through the above formula.
In the UL grant, the hopping flag information may be used to indicate whether to hop frequency in the current uplink transmission. If frequency hopping, 1 bit or 2 bits (which may be denoted as N) of the Most Significant Bits (MSBs) in the FDRA may be assigned according to the resource bandwidth UL,hop ) For indicating the frequency domain offset, i.e. the frequency domain offset value of the second hop relative to the frequency domain offset value of the first hop.

In conjunction with the above description of the FDRA in the UL grant, a case where the UL grant from the base station is received in the random access procedure for the red ap UE is explained.
For example, the maximum bandwidth supported by a RedCap UE is 20M. Under the condition that the subcarrier spacing is 15kHz, the corresponding maximum RB number is 106, the state that FDRA needs to be indicated is 106 x (106 + 1)/2 according to the formula, and the bit number needed by FDRA is 106
Figure BDA0003058722270000087
And (4) respectively. I.e. 13 bits out of 14 bits are occupied for indicating the frequency domain resource location. When the base station schedules the PUSCH frequency hopping transmission, 1 bit or 2 bits of 13 bits are occupied to indicate the frequency offset information, so that the available bits for indicating the state in the FDRA are reduced to 11-12 bits. When the frequency offset information is indicated by 1 bit, the state of the FDRA indication is indicated by slave 2 13 Reduction of =8192 to 2 12 =4096. When 2 bits are used to indicate frequency offset information, the state of FDRA indication is indicated by slave 2 13 =8192 reduction to 2 11 =2048。
Therefore, the number of states which can be indicated by the FDRA is reduced, so that the flexibility of resource allocation is reduced, namely the flexibility of information transmission is reduced.
The application provides an information transmission method and device, which are used for avoiding the problem of reduced flexibility of information transmission caused by scheduling PUSCH frequency hopping transmission by a base station.
Fig. 4 is a schematic flow chart illustrating an information transmission method, where:
step 401, the base station sends the first information to the UE, and correspondingly, the UE receives the first information.
The first information may include at least frequency domain resource allocation information and frequency hopping information.
The frequency domain resource allocation information may also be referred to as PUSCH frequency domain resource allocation information, the frequency domain resource allocation information is information used for indicating a length L of a resource block to be allocated and indicating a start S of the resource block to be allocated in the FDRA, and the UE may determine the frequency domain resource according to the frequency domain resource allocation information and the first resource.
In this application, the frequency domain resource may be understood as a frequency domain resource corresponding to the first time of transmitting the second information between the UE and the base station, that is, a frequency domain resource corresponding to the first hop of transmission. The first resource may be understood as BWP, or initial uplink BWP, or bandwidth supported by the UE, or resource configured by signaling for the base station, etc.
Illustratively, the first resource is 0 to 105 RBs, and if the length L of the resource block is 10 and the starting S of the resource block is 10, the UE may determine that the frequency domain resource is 10 th to 20 th RBs according to the frequency domain resource allocation information and the first resource.
The frequency hopping information includes one or more of frequency hopping identification information and frequency offset information. One or more of the hopping identification information and the frequency offset information may be used to indicate whether to perform hopping transmission between the UE and the base station.
Step 402, the UE transmits second information with the base station according to the first information.
In this application, the first information may be used to schedule the second information, and the UE may determine, according to the first information, a frequency domain resource (also referred to as a PUSCH frequency domain resource) for transmitting the second information, and transmit the second information with the base station on the frequency domain resource.
Illustratively, the first information is a random access response or the first information is DCI, and the second information is a PUSCH. For example, if the first information is a random access response, the second information may be msg3.
In this application, the UE may transmit the second information to the base station for multiple times, and the frequency domain resources corresponding to the multiple transmissions may be the same or different. Taking two transmissions as an example, when the second information is transmitted between the UE and the base station, frequency hopping is not carried out, and corresponding frequency domain resources of the two transmissions are the same; and when the second information is transmitted between the UE and the base station, frequency hopping is carried out, and the frequency domain resources corresponding to the two transmissions are different. The two transmissions may be two repeated transmissions of the same Transport Block (TB), or two transmissions corresponding to two parts of one TB.
Whether to frequency hop when the second information is transmitted between the UE and the base station may be indicated by the frequency hopping information in the first information:
in an optional manner, the frequency hopping information includes frequency hopping identification information, and the frequency hopping identification information may be used to indicate whether to frequency hop when the second information is transmitted between the UE and the base station. If the frequency hopping identification information indicates that the frequency hopping is performed when the second information is transmitted between the UE and the base station, the UE can determine the frequency domain resource of the second hop according to the frequency domain resource of the first hop and the frequency offset, and transmit the second information with the base station on the frequency domain resources of the first hop and the second hop.
In another alternative, the frequency hopping information includes frequency offset information, and the frequency offset information may be used to indicate whether to hop frequency when the second information is transmitted between the UE and the base station. If the frequency offset information indicates frequency hopping when the second information is transmitted between the UE and the base station, the UE may determine the frequency domain resource of the second hop according to the frequency domain resource of the first hop and the frequency offset, and transmit the second information with the base station on the frequency domain resources of the first hop and the second hop.
In the present application, the frequency hopping transmission performed between the UE and the base station may include a first intra-resource frequency hopping transmission (i.e., BWP intra-frequency hopping transmission) and a first out-resource frequency hopping transmission (i.e., BWP out-frequency hopping transmission).
In the first intra-resource frequency hopping transmission, the frequency domain resource of the second hop can be calculated according to the modulus of the first resource bandwidth. Illustratively, the start of resource block of the second hop S = mod (start of resource block of the first hop S + frequency offset, first resource bandwidth). Fig. 5 is a schematic diagram illustrating frequency hopping transmission within the first resource, and as shown in fig. 5, the frequency domain resource of any one frequency hopping transmission is within the first resource. At the first hop, the UE sends msg3 to the base station on the frequency domain resource of the first hop (i.e., the first frequency domain resource); at the second hop, the UE sends msg3 to the base station on the frequency domain resource of the second hop (i.e., the second frequency domain resource), and both transmissions are inside the first resource.
In the first out-of-resource frequency hopping transmission, the frequency domain resource of the second hop may be calculated modulo the size of the second resource. Illustratively, the resource block start of the second hop S = mod (resource block start of the first hop S + frequency offset, second resource size). Fig. 6 is a schematic diagram illustrating a first out-of-resource frequency hopping transmission, for example, in fig. 6, at least one of the frequency domain resources of the second hop is out of the first resource. In the first hop, the UE sends msg3 to the base station on the frequency domain resource of the first hop (i.e. the first frequency domain resource, located in the first resource); at the second hop, the UE sends msg3 to the base station on the frequency domain resources of the second hop (i.e., the second frequency domain resources, which are located outside the first resources).
In this application, the first resource size may be understood as a first resource bandwidth, a BWP bandwidth, the number of RBs included in the first resource, the number of RBs included in the BWP, a first resource length, a subband, and the like.
In this application, the second resource may be a carrier or a frequency domain resource indicated by a signaling. The second resource size may be understood as a second resource bandwidth, a carrier bandwidth, a number of RBs included in the second resource, a number of RBs included in the carrier, a second resource length, and the like.
Implementation mode one
The present application may define a first parameter comprising a maximum value of the length L of the resource block (which may be referred to as a maximum L value), and/or a maximum value of the starting S of the resource block (a maximum S value). Wherein the first parameter corresponding to the frequency hopping transmission is different from the first parameter corresponding to the non-frequency hopping transmission.
Based on the difference of fields contained in the frequency hopping information, the following cases are explained:
situation one
In the case where the hopping identification information is included in the hopping information, the hopping identification information may be used to indicate that hopping transmission is enabled or disabled. Enable hopping is to perform frequency hopping transmissions. The disable (disable) hopping is either no hopping transmission, or the same frequency domain resource for the transmission, or a frequency offset of 0 for multiple transmissions.
For example, the hopping identification information may include 1 bit, and the value of the 1 bit may indicate that the hopping transmission is enabled or disabled. For example, referring to table 3, when the value of the hopping identity information is 1, it indicates that hopping transmission is enabled, that is, hopping is performed when the second information is transmitted between the UE and the base station. And when the value of the frequency hopping identification information is 0, indicating to enable frequency hopping transmission, namely not hopping when the second information is transmitted between the UE and the base station.
TABLE 3
Frequency hopping identification information
1 Enable (enable)
0 Disable (disable)
In an alternative implementation, the first parameter corresponding to enabling frequency hopping transmission is different from the first parameter corresponding to disabling frequency hopping transmission. For example, the maximum S value corresponding to the enabled frequency hopping transmission is smaller than the maximum S value corresponding to the disabled frequency hopping transmission, and/or the maximum L value corresponding to the enabled frequency hopping transmission is smaller than the maximum L value corresponding to the disabled frequency hopping transmission.
In this case, the first parameter corresponding to the enable hopping transmission may be predefined, such as a maximum L value and a maximum S value corresponding to the enable hopping transmission. Or the base station may indicate the first parameter corresponding to the frequency hopping transmission enabled through signaling, for example, the base station indicates the maximum L value and the maximum S value corresponding to the frequency hopping transmission enabled to the UE through a System Information Block (SIB) 1.
In this case, the frequency offset corresponding to the enable hopping transmission may be predefined, such as predefined as
Figure BDA0003058722270000101
Or the base station may indicate, through signaling, a frequency offset corresponding to the enable frequency hopping transmission, for example, the base station indicates, to the UE through SIB1, the frequency offset corresponding to the enable frequency hopping transmission as
Figure BDA0003058722270000102
Likewise, the first parameter corresponding to enabling frequency hopping transmission may be predefined, such as predefined maximum L and maximum S values corresponding to enabling frequency hopping transmission. Or the base station may indicate, through signaling, to disable the first parameter corresponding to the frequency hopping transmission, for example, the base station indicates, to the UE, a maximum L value and a maximum S value corresponding to the frequency hopping transmission, which are disabled through SIB 1.
Situation two
In the case where the frequency offset information is included in the frequency hopping information, the frequency offset information indicates a frequency offset, and is particularly useful for indicating a frequency offset value. In this implementation, a value set of the frequency offset may be preset, where the value set of the frequency offset includes a plurality of frequency offset values, and the plurality of frequency offset values may include a frequency offset value 0 and one or more non-0 frequency offset values. Wherein the frequency offset value of 0 is understood as no frequency hopping, or no frequency hopping is enabled, or the frequency offset value of 0 is used for transmitting the second information between the UE and the base station. A non-0 frequency offset value may be understood as frequency hopping when transmitting the second information between the UE and the base station, or enabling frequency hopping, or a frequency offset value of non-0. Each frequency domain offset value corresponds to frequency offset information.
Exemplarily, as shown in table 4, one kind of frequency offset information exemplarily provided for the present application indicates a correspondence of frequency offsets. The frequency offset information occupies 2 bits, and the frequency offset information may indicate 4 frequency offsets, where the 4 frequency offsets include a frequency offset value of 0 and 3 non-0 frequency offset values.
And when the frequency offset information value is 00, indicating that the frequency offset value of the frequency hopping transmission between the UE and the base station is 0.
And when the frequency offset information value is 01, indicating that the frequency offset value of frequency hopping transmission between the UE and the base station is N1/2.
And when the frequency offset information value is 10, indicating that the frequency offset value of frequency hopping transmission between the UE and the base station is N1/4.
And when the frequency offset information value is 11, indicating that the frequency offset value of frequency hopping transmission between the UE and the base station is M/2.
Where N1 may be a first resource size and M may be a second resource size. Taking the above frequency offset information as 01 for example, the first resource includes 106 RBs, i.e. N1 equals 106, and the frequency offset between the first hop and the second hop of the ue and the base station is 53 RBs.
TABLE 4
Frequency offset information
00 0
01 N1/2
10 N1/4
11 M/2
Further, the frequency offset information may indicate the first intra-resource frequency hopping or the first out-of-resource frequency hopping. As shown in table 4, when the frequency offset information is 01 or 10, the UE and the base station are instructed to perform frequency hopping transmission of the second information in the first resource. And when the frequency offset information value is 11, indicating the UE and the base station to perform frequency hopping transmission of second information outside the first resource.
In an alternative implementation, the first parameter corresponding to the non-0 frequency offset value is different from the first parameter corresponding to the frequency offset value 0. For example, the maximum S value corresponding to the non-0 frequency offset value is smaller than the maximum S value corresponding to the frequency offset value 0, and/or the maximum L value corresponding to the non-0 frequency offset value is smaller than the maximum L value corresponding to the frequency offset value 0.
In this case, the first parameter corresponding to the non-0 frequency offset value may be predefined, such as predefined maximum L value and maximum S value corresponding to the non-0 frequency offset value; or the base station may indicate the first parameter corresponding to the non-0 frequency offset value through signaling, for example, the base station indicates the maximum L value and the maximum S value corresponding to the non-0 frequency offset value to the UE through SIB 1.
Similarly, a first parameter corresponding to the frequency offset value 0 may be predefined, such as a maximum L value and a maximum S value corresponding to the frequency offset value 0; or the base station may indicate the first parameter corresponding to the frequency offset value 0 through signaling, for example, the base station indicates the maximum L value and the maximum S value corresponding to the frequency offset value 0 to the UE through SIB 1.
Situation three
In the case where the frequency offset information is included in the frequency hopping information, the bit states of the frequency offset information may include two kinds, which may be represented as a first state and a second state. When the bit state of the frequency offset information is the first state, the frequency offset information indicates that frequency hopping is enabled, that is, indicates a frequency offset other than 0. When the bit state of the frequency offset information is the second state, the frequency offset information indicates that frequency hopping is disabled, i.e., the frequency offset value is 0.
Illustratively, as shown in table 5, for an exemplary correspondence relationship between frequency offset information and frequency offset provided in this application, for example, the frequency offset information includes 2 bits, the first state may include values of the frequency offset information of 01, 10, and 11, and the second state may include values of the frequency offset information of 00. As shown in table 5:
and when the frequency offset information value is 00, indicating the UE to enable frequency hopping transmission, namely, not carrying out frequency hopping transmission between the UE and the base station.
And when the frequency offset information value is 01, indicating that the frequency offset value for performing frequency hopping transmission between the UE and the base station is N1/2.
And when the frequency offset information value is 10, indicating that the frequency offset value for performing frequency hopping transmission between the UE and the base station is N1/4.
And when the frequency offset information value is 11, indicating that the frequency offset value for performing frequency hopping transmission between the UE and the base station is M/2.
Where N1 may be a first resource size and M may be a second resource size. Taking the above frequency offset information as 01 for example, the first resource includes 106 RBs, i.e. N1 equals 106, and the frequency offset between the first hop and the second hop of the ue and the base station is 53 RBs.
TABLE 5
Frequency offset information
00 Disable (disable)
01 N1/2
10 N1/4
11 M/2
Further, the frequency offset information may indicate the first intra-resource frequency hopping or the first out-of-resource frequency hopping. As shown in table 5, when the frequency offset information takes a value of 01 or 10, the UE and the base station are instructed to perform frequency hopping transmission of second information in the first resource; and when the frequency offset information value is 11, indicating the UE and the base station to perform frequency hopping transmission of second information outside the first resource.
In an alternative implementation, the first parameter corresponding to enabling frequency hopping is different from the first parameter corresponding to disabling frequency hopping. For example, the maximum S value corresponding to enabled frequency hopping is smaller than the maximum S value corresponding to disabled frequency hopping, and/or the maximum L value corresponding to enabled frequency hopping is smaller than the maximum L value corresponding to disabled frequency hopping.
In this case, the first parameter corresponding to the enable hopping may be previously specified, such as a maximum L value and a maximum S value corresponding to the enable hopping; or the base station may indicate, through signaling, the first parameter corresponding to the enabled frequency hopping, for example, the base station indicates, to the UE, the maximum L value and the maximum S value corresponding to the enabled frequency hopping through SIB 1.
Similarly, the first parameter corresponding to the disable hopping may be predefined, such as the maximum L value and the maximum S value corresponding to the disable hopping; or the base station may indicate the first parameter corresponding to the disabled frequency hopping through signaling, for example, the base station indicates the maximum L value and the maximum S value corresponding to the disabled frequency hopping to the UE through SIB 1.
It should be noted that, in the first to third cases, the maximum S value and the maximum L value in the first parameter may also be configured in different ways. For example, the maximum L value corresponding to the enabled frequency hopping may be predefined, and the maximum S value corresponding to the enabled frequency hopping is indicated by the base station through signaling. For another example, the maximum S value corresponding to the enabled frequency hopping may be predefined, and the maximum L value corresponding to the enabled frequency hopping is indicated by the base station through signaling. The determination method of the maximum S value and the maximum L value corresponding to the disable frequency hopping is similar to the above, and is not described again.
In the existing scheme, the state indicated by the frequency domain resource allocation information is caused by the fact that the frequency offset information occupies 2 bits, and the frequency offset information is originally in a secondary 2 state 13 Is reduced to 2 11 Accordingly, the number of RIVs that the frequency domain resource allocation information can indicate becomes smaller. Based on the above numbering formulas of the RIV, only the first 2048 states can be indicated. Combinations of resource block start S and resource block length L with RIV exceeding 2048 (number of states indicated by 11 bits)Can be indicated that the base station cannot allocate resources when allocating them, resulting in a limited resource allocation. At this time, the frequency domain resources that the base station can allocate are resource allocation combinations of a resource block length L of less than or equal to 20 RBs and a resource block length L of greater than or equal to 89 RBs. That is, frequency domain resources having a resource block length L between 1 RB and 20 RBs and frequency domain resources having a resource block length L between 89 RBs and 106 RBs may be indicated, while frequency domain resources having a resource block length L between 21 RBs and 88 RBs may not be indicated.
Considering that the interference degree or fading and the like are different when information is transmitted on different frequency domain resources, the same information can be transmitted on different frequency domain resources by adopting a frequency hopping mode, the occupied frequency domains have far difference as far as possible when the information is transmitted for many times, and the whole BWP is traversed, so that the larger frequency diversity gain is obtained. Correspondingly, the diversity gain generated by the frequency-hopping transmission of the frequency-domain resource with the shorter resource block length L is greater than the diversity gain generated by the frequency-hopping transmission of the frequency-domain resource with the longer resource block length L.
Based on the above analysis, in the process of transmitting the second information between the UE and the base station, the maximum S value corresponding to the enabled frequency hopping is smaller than the maximum S value corresponding to the disabled frequency hopping, and/or the maximum L value corresponding to the enabled frequency hopping is smaller than the maximum L value corresponding to the disabled frequency hopping, which is helpful for improving the flexibility of resource indication, that is, the flexibility of transmitting the second information.
The manner of determining the maximum S value and/or the maximum L value is explained as follows.
The frequency offset information may occupy 1 bit or 2 bits. In the case that the frequency offset information occupies 1 bit, it may be set that the frequency offset information occupies 1 bit in the FDRA (14 bits) before truncation, that is, the FDRA (14 bits) includes frequency domain resource allocation information and frequency offset information, wherein the frequency domain resource allocation information occupies 13 bits and the frequency offset information occupies 1 bit. In this way, the maximum number of RIVs that can be indicated by the frequency domain resource allocation information is not affected.
In the case that the frequency offset information occupies 2 bits, the frequency offset information may be set to occupy 2 bits in the FDRA (14 bits) before truncation, that is, the FDRA (14 bits) before truncation includes frequency domain resource allocation information and frequency offset information, where the frequency domain resource allocation information occupies 12 bits, and the frequency offset information occupies 2 bits.
The following is explained for the case where the frequency domain resource allocation information occupies 12 bits.
Implementation 1, limiting maximum L value
In an alternative implementation manner, the maximum L value is determined according to the number of bits that can be occupied by the frequency domain resource allocation information and the size of the first resource (i.e., the number of RBs included in the first resource). The number of RBs included in the first resource may be represented as N1, the maximum L value may be represented as N2, N1 and N2 are positive integers, and N1> N2.
In an optional implementation manner, according to the number N1 of RBs and the maximum L value N2 included in the first resource, the number of bits occupied by the frequency domain resource allocation information is determined to be
Figure BDA0003058722270000131
The number of bits occupied by the frequency domain resource allocation information is 12, and the value of N2 can be determined under the condition of determining N1. For example, when N1=106, N2=50 may be determined. Accordingly, the starting S of resource blocks of the frequency domain resources may be any number from 0 to 105. The resource block length L of the frequency domain resources may be any number from 1 to 50.
Further, the present application provides a numbering formula for an RIV:
Figure BDA0003058722270000132
Figure BDA0003058722270000141
in the case where N1=106 and N2=50 are combined, the maximum value of the obtained RIV is 4074. The number of RIVs which can be indicated by the frequency domain resource allocation information is increased, and the frequency domain resources with smaller resource block length L can be indicated, so that the diversity gain of the frequency domain resources is improved.
Referring to a resource allocation diagram schematically shown in fig. 7, the relationship between N1 and N2 is explained. The starting S of the resource block of frequency domain resource 1 is S1, the starting S of the resource block of frequency domain resource 2 is S2, and the starting S of the resource block of frequency domain resource 3 is S3, where S1=0, S3= (N1-N2 + 1), and S1 < S2 < S3.
Implementation 2, limiting maximum L and S values
In an alternative implementation manner, the maximum L value and the maximum S value are determined according to the number of bits included in the frequency domain resource allocation information and the size of the first resource (i.e., the number of RBs included in the first resource). The number of RBs included in the first resource may be represented as N1, the maximum L value may be represented as N3, N1 and N3 are positive integers, and N1> N3.
In an alternative implementation, the maximum L value is N3, the maximum S value is N3-1, and N1>And N3. The bit number occupied by the frequency domain resource allocation information is
Figure BDA0003058722270000142
If the number of bits included in the frequency domain resource allocation information is 12, the value of N3 can be determined. For example, when N1=106, it may be determined that N3=90, the starting S of the resource blocks of the frequency domain resources may be any number from 0 to 89, and the length L of the resource blocks of the frequency domain resources may be any number from 1 to 90.
In the above examples of N1=106 and N3=90, the maximum value of the obtained RIV was 4074. The number of RIVs which can be indicated by the frequency domain resource allocation information is increased, and the frequency domain resources with smaller resource block length L can be indicated, so that the diversity gain of the frequency domain resources is improved.
In this case, the number of bits that the frequency domain resource allocation information can occupy is less than 13, and 1 bit of the 13 bits may be further used as the start indication information. The start indication information may be used for information indicating a resource block start S of the frequency domain resources or may be used for indicating a position of the frequency domain resource allocation within the first resources. For example, the information of the resource block start S may be a range of the resource block start S. For example, the range of the resource block start S may be in a lower resource range within the first resource or in a higher resource range within the first resource.
For example, when the value of the start indication information is 0, the range of the start S of the resource block is 0 to (N3-1); when the value of the initial indication information is 1, the initial S range of the resource block is (N1-N3 + 1) to (N1-1).
For example N1=106, N3=63. For example, when the value of the start indication information is 0, the range of the start S of the resource block is 0 to 62; when the value of the start indication information is 1, the range of the resource block start S is 44 to 105.
Referring to another resource allocation diagram, which is schematically shown in fig. 8, the relationship between N1 and N3 is explained. When the value of the start indication information is 0, as shown in fig. 8 (a), the range of the start S of the resource block is in the lower resource range of the first resource, specifically, the start S of the resource block of both frequency domain resource 1 and frequency domain resource 2 is less than N3, where the start S1 of the resource block of frequency domain resource 1 is 0. When the value of the start indication information is 1, as shown in fig. 8 (b), the range of the start S of the resource block is in a higher resource range in the first resource, specifically, the start S of the resource block of the frequency domain resource 1 and the start S of the resource block of the frequency domain resource 2 are both greater than N1-N3+1, where the start S1 of the resource block of the frequency domain resource 1 is N1-N3+1.
In the above technical solution, under the condition that the maximum bandwidth of the red beacon UE is limited, by limiting the maximum L value of the PUSCH frequency domain resource, or by limiting the maximum L value and the maximum S value of the PUSCH frequency domain resource, the bit resource can be effectively utilized, better resource allocation flexibility is provided for the red beacon UE, and the flexibility of transmitting the second information between the red beacon UE and the base station is facilitated.
Implementation mode two
In this application, it may be defined that the frequency domain resource allocation information in the first information includes 13 bits. Based on the difference of fields contained in the frequency hopping information, the following cases are explained:
implementation a
The frequency hopping information includes frequency hopping identification information and frequency offset information, and there is no association between the number of bits included in the frequency offset information and the size of the first resource. Illustratively, the frequency hopping identification information occupies 1 bit in the frequency hopping information, and is used for indicating whether an offset occurs when the second information is transmitted between the UE and the base station; the frequency offset information occupies 1 bit in the frequency hopping information and is used for indicating the value of the frequency offset when the second information is transmitted between the UE and the base station in a frequency hopping mode.
Specifically, the first information includes fields as shown in table 6. Wherein the frequency hopping identification information and the frequency offset information respectively comprise 1 bit; the frequency domain resource allocation information may include 13 bits, and may indicate 2 13 =8192 locations of frequency domain resources, i.e. 8192 combinations of resource block length L and resource block start S can be indicated.
TABLE 6
First information Number of bits
Frequency hopping identification information 1

Frequency offset information 1
In one example, the frequency offset information indicates 2 frequency offsets. The 2 frequency offsets are each a frequency offset of the UE within the first resource range. For example, two frequency offsets indicated by the frequency offset information can be shown in table 7, and when the frequency offset information takes a value of 0, the frequency offset value indicating frequency hopping transmission between the UE and the base station is N1/2. And when the frequency offset information value is 1, indicating that the frequency offset value of frequency hopping transmission between the UE and the base station is N1/4.
TABLE 7

1 N1/4
In yet another example, the frequency offset information indicates 2 frequency offsets. The 2 frequency offsets include frequency offsets for the UE within the first range of resources and frequency offsets for the UE outside the first range of resources. For example, two frequency offsets indicated by the frequency offset information may be shown in table 8, and when the frequency offset information takes a value of 0, the UE and the base station are indicated to perform frequency offset in the first resource. And when the frequency offset information value is 1, indicating the UE and the base station to perform frequency offset outside the first resource. In the present application, outside the first resource range may also be understood as being within the second resource range.

In the above technical solution, there is no association between the number of bits (1 bit) occupied by the frequency offset information in the first information and the size of the first resource, so as to ensure that the number of bits that can be occupied by the frequency domain resource allocation information is 13, which is helpful for ensuring the flexibility of resource allocation and implementing the flexibility of transmitting the second information between the UE and the base station.

The frequency hopping information includes frequency offset information (does not include hopping identification information). For example, the frequency offset information is used to indicate a frequency offset. In the frequency offsets indicated by the frequency offset information, at least one frequency offset value is related to the first resource size, and at least one frequency offset value is related to the second resource size.
In the present application, the fields included in the first information may be as shown in table 9. Wherein the frequency domain resource allocation information comprises 13 bits, the frequency domain resource allocation information can indicate 2 13 The position of the 8192 frequency domain resources can indicate the combination of the 8192 resource block length L and the resource block start S.

Implementation c
The frequency hopping information includes at least frequency offset information, the frequency offset information and a second parameter indicating a frequency offset. Illustratively, the second parameter may have two bit states, which may be represented as a third state and a fourth state. When the bit state of the second parameter is a third state, the second parameter indicates that the frequency offset is determined according to the first resource size and the frequency offset information. The second parameter indicates that the frequency offset is determined according to the second resource size and the frequency offset information when the bit state of the second parameter is a fourth state.
In the present application, the fields included in the first information may be as shown in table 11. Wherein the frequency domain resource allocation information comprises 13 bits, the frequency domain resource allocation information can indicate 2 13 =8192 locations of frequency domain resources, that is, a combination of 8192 resource block lengths L and resource block starting S can be indicated. For example, the frequency offset information includes 2 bits, which can be used to indicate 4 kinds of frequency offsets. For example, the second parameter includes 1 bit. For example, if the value of the 1 bit is 1, the bit state representing the second parameter is a third state; if the 1 bit is 0, the bit state representing the second parameter is the fourth state.

Based on the first and second implementation manners, the frequency domain resource allocation information may include 13 bits, and the 13 bits may indicate 2 13 The location of the =8192 frequency domain resources helps to improve the flexibility of information transmission. In addition, in the present application, the number of bits included in the frequency domain resource allocation information may also be determined according to a third resource size, where the third resource may be the first resource or a predefined resource, and the third resource size may be a third resource bandwidth, the number of RBs included in the third resource, a third resource length, and the like.

Further, in the case where 2 bits are included in the frequency offset information (i.e., example (2) and example (4) described above), the channel state information request may not be included in the first information. That is, 1 bit included in the channel state information request in the existing scheme is used to carry the frequency offset information. Illustratively, the fields included in the first information may be as shown with reference to tables 14 (a) and 14 (b).

In the technical scheme, the indication domains in the first information, such as the frequency offset information, the frequency hopping identification information, the frequency domain resource allocation information and the like, are redesigned, so that the problem that certain RIVs cannot be scheduled due to the fact that the frequency offset information occupies the available state of the FDRA domain, and the influence on the flexibility of the base station for scheduling the RedCap UE to transmit the second information is avoided.
Through the above manner, the first information may include reserved bits, and the reserved bits may be used to carry transmission information. For example, the first information includes transmission information. For example, the transport message may specifically be a transport message of Msg3 and/or Msg 4.
Illustratively, the transmission information may include at least one of: (1) the number of repetitions of PUSCH; (2) the number of repetitions of PDSCH; (3) the number of repetitions of the PUCCH; (4) frequency hopping information of the PUCCH; (5) a TBS scaling factor; (6) EDT transmission; (7) reporting the UE capability; (8) combining the reported capabilities of the UE; (9) whether to report the UE type.
In the transmission information, for example, the number of repetitions of the PUSCH is the number of repetitions of Msg3, or the size of the time domain resource occupied by Msg3. For example, the number of repetitions of the PDSCH is Msg 4. For example, the number of repetitions of the PDSCH is in the relationship of Msg4 and Msg3. For example, the number of repetitions of PDSCH is a multiple of the number of repetitions of Msg3.
For example, PUCCH is feedback information of Msg 4. For example, the number of repetitions of the PDSCH is a relationship between the number of repetitions of the PUCCH and the Msg3. For example, the number of repetitions of PUCCH is a multiple of the number of repetitions of Msg3. If the transmission information is at least 2, the number of repetitions of the PUCCH is Msg3 × 2.
For example, the EDT transmission is an early data transmission (early data transmission), and the EDT transmission is used to indicate that the data message is transmitted in Msg3 or not transmitted in Msg3.
For example, the TBS scaling factor is the scaling factor of the Msg3 transport block size.
For example, the reporting mode of the UE capability is a channel or signaling for carrying information reported by the UE capability. For example, the UE capability is at least one of: the maximum number of layers supported by the UE, the maximum number of antennas supported by the UE, the bandwidth supported by the UE, the duplex capability supported by the UE, the maximum modulation mode supported by the UE, and the like. For example, the signaling for carrying the information reported by the UE capability is Msg3, msg5, or PUSCH.
For example, the capability reported by the UE may be understood as UE capability. For example, the capability combination reported by the UE includes at least one of the following: {1Rx/2Rx }, {1MIMO layer/2MIMO layer }, { HD-FDD/FD-FDD }, {64QAM/256QAM }. For example, the first information indicates the capability combination reported by the UE from at least one candidate combination of capability combinations reported by the UE. For example, at least one candidate combination may be preconfigured. For example, at least one candidate combination is SIB1 configured. For example, at least one candidate combination may be predefined. For example, the 6 candidate combinations are {1Rx/1MIMO layer, HD-FDD }, {2Rx/2MIMO layer, HD-FDD }, {1Rx/1MIMO layer, FD-FDD }, {2Rx/2MIMO layer, FD-FDD }, respectively.
For example, the first information indicates that the second information reports the UE type, or the first information indicates that the second information does not report the UE type. The UE type may be a reccap UE, or a legacy UE, or an eMBB UE.
The different capabilities of the UEs, or the distinction of different types of UEs, may include at least one of:
1. the bandwidth capabilities are different. For example, the carrier bandwidth of the first UE is not greater than 50MHz, for example, at least one of 50MHz, 40MHz, 20MHz, 15MHz, 10MHz, or 5MHz, and the carrier bandwidth of the second UE is greater than 50MHz.
2. The number of the transmitting and receiving antennas is different. For example, the first UE may support 2 receive-1 transmit (2 receive antennas and 1 transmit antenna), or 1 receive-1 transmit (1 receive antenna and 1 transmit antenna). The second UE may support 4 receive and 2 transmit (4 receive antennas and 2 transmit antennas). It can be understood that, under the condition of achieving the same data transmission rate, since the number of transceiving antennas of the first UE is less than that of transceiving antennas of the second UE, the maximum coverage range that can be achieved by data transmission between the first UE and the base station is less than that of data transmission between the second UE and the base station.
3. The maximum uplink transmit power is different. For example, the uplink maximum transmit power of the first UE may be one of 4 decibel-milliwatts (dBm) to 20 dBm. The uplink maximum transmit power of the second UE may be 23dBm or 26dBm.
4. The protocol versions are different. The first UE may be a UE in NR Release 17 (Release-17, rel-17) or in a later version of NR Rel-17. The second UE may be, for example, a UE in NR Release 15 (Release-15, rel-15) or NR Release 16 (Release-16, rel-16).
5. The carrier aggregation capabilities are different. For example, the first UE may not support carrier aggregation and the second UE may support carrier aggregation. For another example, both the first UE and the second UE may support carrier aggregation, but the maximum number of carrier aggregation simultaneously supported by the first UE is smaller than the maximum number of carrier aggregation simultaneously supported by the second UE, for example, the first UE supports aggregation of 2 carriers at most simultaneously, and the second UE may support aggregation of 5 carriers or 32 carriers at most simultaneously.
6. The duplex capabilities are different. For example, the first UE supports half-duplex Frequency Division Duplexing (FDD). The second UE supports full duplex FDD.
7. The processing time capability of the data is different. For example, the minimum delay between the first UE receiving the downlink data and sending the feedback for the downlink data is greater than the minimum delay between the second UE receiving the downlink data and sending the feedback for the downlink data; and/or the minimum time delay between the first UE sending the uplink data and receiving the feedback of the uplink data is larger than the minimum time delay between the second UE sending the uplink data and receiving the feedback of the uplink data.
8. The processing power (ability/capability) differs. For example, the baseband processing capability of the first UE is lower than the baseband processing capability of the second UE. Wherein the baseband processing capability may include at least one of: the UE may include a maximum multiple-input multiple-output (MIMO) layer number supported by the UE when performing data transmission, a hybrid automatic repeat request (HARQ) process number supported by the UE, and a maximum Transport Block Size (TBS) supported by the UE.
9. The transmission peak rates of the uplink and/or downlink are different. The transmission peak rate refers to the maximum data transmission rate that the UE can achieve per unit time (e.g., per second). The peak uplink rate supported by the first UE may be lower than the peak uplink rate supported by the second UE, and/or the peak downlink rate supported by the first UE may be lower than the peak downlink rate supported by the second UE. For example, the uplink peak rate of the first UE is less than or equal to 50Mbps, the downlink peak rate is less than or equal to 150Mbps, the uplink peak rate of the second UE is greater than or equal to 50Mbps, and the downlink peak rate is greater than or equal to 150Mbps. For another example, the uplink peak rate or downlink of the first UE is in the order of hundreds Mbps, and the uplink peak rate or downlink peak rate of the second UE is in the order of Gbps.
10. The buffers (buffers) vary in size. The buffer may be understood as a Layer 2 (L2) buffer total size, which is defined as a sum of a number of bytes buffered in a Radio Link Control (RLC) transmission window and a reception and reordering window and a number of bytes buffered in a Packet Convergence Protocol (PDCP) reordering window for all radio bearers by the UE. Alternatively, buffer may be understood as the total number of soft channel bits that can be used by the HARQ process.
Optionally, in this embodiment of the present application, the first UE is different from the second UE, and the first UE may be a reduce UE in an NR system, or the first UE may also be referred to as a low-capability UE, a Reduced-capability UE, a reduce UE, a Reduced Capacity UE, an mtc UE, or the like. Other UEs may also be included in the NR system, such as a second UE, which may be a Legacy capability/normal capability/high capability UE, and may also be referred to as a Legacy UE or NR Legacy (NR Legacy) UE, and the second UE has the above-mentioned distinguishing features from the first UE.
Taking the transmission information including the repetition times as an example:
in an example, the first information may not include the channel state information request, that is, 1 bit included in the channel state information request in the existing scheme is used to carry the repetition number. The fields included in the first information may be as shown with reference to table 15.
Watch 15
Figure BDA0003058722270000211
In another example, the first information may not include the frequency hopping identification information and the channel state information request, that is, 1 bit included in the frequency hopping identification information and 1 bit included in the channel state information request in the existing scheme are used to carry the frequency offset information and the repetition number. The fields included in the first information may be as shown with reference to table 16.

In another example, the first information may not include the channel state information request, that is, 1 bit included in the channel state information request in the existing scheme is used to carry the repetition number. Further, the frequency offset information in the first information may include 1 bit, and the repetition number may include 2 bits. The fields included in the first information may be as shown with reference to table 17.
TABLE 17
Figure BDA0003058722270000222
In the above technical solution, the first information does not include a field, and the number of bits of the field in the first information may be understood to be 0. For example, the first information does not include the channel state information request, and it can be understood that the bit number of the channel state information request in the first information is 0; the first information does not include the frequency hopping identification information, and it can be understood that the number of bits of the frequency hopping identification information in the first information is 0, and the like.
In the above technical solution, the first information may further include transmission information, for a red beacon UE, due to capability restrictions such as a maximum supportable bandwidth and a maximum number of antennas, coverage of the red beacon UE is limited, and a capability of receiving or transmitting information is lower than that of a conventional terminal device. Therefore, it is necessary to enhance the information received or transmitted by the red map UE, for example, by using a repetition or frequency hopping method, which helps to improve the quality of information transmission.
