Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a data transmission method, an apparatus, a user equipment, a network device, and a storage medium.
Background
In the 3rd Generation Partnership Project (3 GPP) protocol, User Equipments (UEs) are divided into lightweight UEs (Reduced Capability UEs, red map UEs) and non-lightweight UEs (non-Reduced Capability UEs, non-red map UEs). The non-RedCap UEs include enhanced Mobile broadband (eMBB) UEs and ultra-reliable low latency communication (URLLC) UEs.
In practical applications, a RedCap UE and a non-RedCap UE may access the same cell. In the specific random access process, when the UE transmits a part of the message, the UE may hop within the time slot in order to obtain the frequency diversity gain. Since the maximum bandwidth supported by the non-red beacon UE is 100MHz, and the maximum bandwidth configurable for the initial upstream BWP is 100MHz, it is highly likely that the initial upstream BWP will exceed the maximum bandwidth supported by the red beacon UE itself by 20 MHz. For a red hop UE, when a dedicated initial uplink BWP is not configured, and the red hop UE and a non-red hop UE share an initial UL BWP, and the initial uplink BWP may exceed 20MHz, when the UE hops within a timeslot, according to the requirements of the existing protocol, the frequency interval between two hops will be greater than the maximum bandwidth supported by the red hop UE, so that the red hop UE needs to adjust the center frequency point between two hops, and needs a certain time to perform radio frequency modulation.
However, according to the existing protocol, when the UE hops within a timeslot, the two adjacent hops should be consecutive in time, so that the UE does not have time to perform radio frequency modulation.
In practical applications, the network may configure a special initial uplink BWP for the red map UE to perform intra-slot hopping data transmission.
However, when the network does not configure a special initial uplink BWP for the reccap UE, how to complete the intra-slot hopping data transmission becomes a problem to be solved urgently.

Detailed Description
Fig. 1 shows a possible communication system to which the data transmission method provided in the embodiment of the present invention is applicable, where the architecture of the communication system includes: a base station and a plurality of user equipments (user equipment 1, user equipment 2, user equipment 3 and user equipment 4 as shown in the figure). Wherein:
the base station is used for providing wireless access service for user equipment in a cell controlled by the base station. For example, as shown in fig. 1, the base station controls a cell 1 and a cell 2, and provides radio access services for user equipment in the cell 1 (e.g., user equipment 1 and user equipment 2 in fig. 1) and user equipment in the cell 2 (e.g., user equipment 3 and user equipment 4 in fig. 1), respectively.
And the user equipment is used for carrying out data service by accessing the base station to which the cell belongs. For example, in fig. 1, both the user equipment 1 and the user equipment 2 are in the coverage area of the cell 1 controlled by the base station, and both access to the base station to perform data service; and the user equipment 3 and the user equipment 4 are both accessed to the base station to carry out data service in the coverage range of the cell 2 controlled by the base station.
Specifically, the multiple user equipments need to establish connection with the base station through a random access procedure, so that the multiple user equipments implement data service through accessing the base station.
It should be noted that the communication system shown in fig. 1 is only an example and is not limited to include the base station and the plurality of user equipments shown in fig. 1. The communication system may also include a plurality of base stations, as well as other devices, which are not specifically listed herein.
In practical applications, for data to be transmitted, to obtain frequency diversity gain, the UE may perform intra-slot frequency hopping, for example, in a contention-based or non-contention-based random access process. It can be understood that, when performing uplink transmission in other situations or scenarios, intra-slot frequency hopping may also be required, and the specific application scenario is not limited.
The following describes the data transmission method in detail, taking a contention-based random access procedure and a non-contention-based random access procedure as examples.
Fig. 2 is a schematic diagram of signaling interaction between a UE and a base station gNB in a four-step random access process. The specific random access process is as follows:
in step 101, the UE sends a random access request Msg1 to the gNB.
Random Access request (Random Access Preamble), namely Msg 1. In a specific implementation, the random access request Msg1 includes a random access preamble (random access preamble) code.
A Random Access Response (Random Access Response), namely Msg2, is a Response message of the base station after receiving the Random Access request Msg 1.
A Scheduled Transmission request (Msg 3).
The radio resource control connection request Msg3 includes a PUSCH to be transmitted.
Radio resource control establishment (context Resolution), namely Msg 4. And the radio resource control establishment Msg4 contains the identity of the UE and is used for informing the UE of successful random access.
In a specific implementation, after receiving the radio resource control setup Msg4, the UE feeds back uplink control information to the base station to inform the base station whether the radio resource control setup Msg4 is correctly received. The downlink Control signal is sent to the UE through a Physical Uplink Control Channel (PUCCH), and for convenience of description, in the embodiment of the present invention, the downlink Control signal is used to feed back, to the base station, whether Uplink Control information of radio resource Control Msg4 is correctly received, which is referred to as PUCCH for short.
In the random access process shown in fig. 2, when the UE sends a random access message Msg3, for a PUSCH in which transmission is required, the UE may complete data transmission by using intra-slot frequency hopping. And when the UE feeds back the uplink control information after receiving the conflict resolution message Msg4, the UE can also adopt a frequency hopping mode in the time slot to finish the sending of the PUCCH.
Fig. 3 is a schematic diagram of signaling interaction between a UE and a base station gNB in a two-step random access process.
The specific random access process is as follows:
in step 201, the UE sends a first message MsgA to the gNB.
The first message MsgA includes random access preamble information and a PUSCH required to be transmitted. The UE sends a random access preamble to the gNB, and then sends a PUSCH to be transmitted.
In step 202, the gNB sends a second message MsgB to the UE.
The second message MsgB may include a sequence number of a random access preamble, a cell radio network temporary identifier, and a UE identifier that is successfully accessed.
In the random access process shown in fig. 3, when the UE sends the first message MsgA, the UE may complete data transmission by using a frequency hopping within a time slot for a PUSCH in which transmission is required.
The intra-slot frequency hopping refers to splitting one transport block into a plurality of parts, and transmitting the parts at a plurality of frequency domain positions of the same channel. The time domain resource of the transmission block is located in a time slot, the frequency domain position corresponding to each part of data is different, and each frequency domain position sends a part of the transmission block.
The transmission block is split into N parts, frequency hopping in a time slot can be divided into N hops, and N is more than or equal to 2 and is a positive integer. For example, if a transport block is divided into two parts and transmitted at two different frequency domain locations on the same channel, the frequency hopping pattern in a timeslot is two hops. One part of the transport block is called a first hop of the transport block and the other part is called a second hop of the transport block.
In the existing protocol, when frequency hopping transmission in a time slot needs to be performed, two adjacent hops should be continuous in time, that is, time domain resources are not additionally configured for the UE to perform radio frequency modulation.
Taking N as an example, the two adjacent hops are consecutive in time: in the time domain resource configured by the base station for transmitting the transport block, the end time of the first hop of the transport block is the start time of the second hop of the transport block, or the end time of the second hop of the transport block is the start time of the first hop of the transport block.
In practical applications, the network may configure a dedicated initial uplink BWP for the recmap UE to complete the intra-slot hopping of data transmission.
However, since the maximum bandwidth supported by the non-red beacon UE is 100MHz, and the maximum bandwidth configurable for the initial upstream BWP is 100MHz, it is highly likely that the initial upstream BWP will exceed the maximum bandwidth supported by the red beacon UE itself by 20 MHz. At this time, for the red beacon UE, if no dedicated initial uplink BWP is configured, and the red beacon UE and the non-red beacon UE share the initial UL BWP, when the UE transmits the Radio resource control connection request Msg3, the PUSCH in the first message MsgA, or feeds back the Radio resource control to establish whether the Msg4 correctly receives the PUCCH, if intra-slot Frequency hopping is required, the Frequency interval between two hops may be greater than the maximum bandwidth supported by the red beacon UE, so that the red beacon UE needs to adjust the central Frequency point between two hops, that is, needs to perform Radio Frequency (RF) Frequency modulation (tuning) for a certain time, and can perform intra-slot Frequency hopping data transmission after adjusting the current central Frequency point to the central Frequency (i.e., Radio Frequency) of the next hop.
When the network does not configure a special initial uplink BWP for the reccap UE, how to complete frequency hopping data transmission in the timeslot becomes a problem to be solved urgently.
In order to solve the problem, the present invention provides a data transmission method, when a user equipment determines a frequency domain resource for transmitting first data based on the frequency domain resource configuration information, the total bandwidth of a first resource and a second resource for transmitting the first data in the frequency domain is controlled to be less than or equal to a maximum bandwidth supported by the user equipment, or an interval between the first resource and the second resource for transmitting the first data in the time domain is greater than or equal to a time length user equipment for radio frequency modulation, and frequency hopping transmission of data in a time slot is completed.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Example 1
Referring to fig. 4, an embodiment of the present invention provides a data transmission method, where the method may include the following steps:
In a specific implementation, the first data may be any data to be transmitted that needs frequency hopping transmission in a time slot.
In a specific implementation, the resource configuration information may include: time domain resource configuration information and frequency domain resource configuration information. The time domain resource allocation information and the frequency domain resource allocation information for transmitting the first data may be received in various ways. The time domain resource allocation information and the frequency domain resource allocation information may also be in various forms, and are not limited specifically.
For example, referring to fig. 2, in the four-step random access process, when the first data is a PUSCH, the base station may send time domain resource allocation information and frequency domain resource allocation information through an access response message Msg 2. Referring to fig. 3, in the two-step random access procedure, when the first data is a PUSCH, the base station may send the time domain resource allocation information and the frequency domain resource allocation information in a broadcast manner or the like.
When The first data is a PUSCH, The time domain resource configuration information of The first data may include identification information of an initial Orthogonal Frequency Division Multiplexing (OFDM) symbol for transmitting The first data, and a total Length of a time domain resource, which may specifically be represented by an initial and Length Indicator (SLIV) value.
TABLE 1
The frequency domain resource configuration information of the first data may include: the total length of the frequency domain resources, the identification information of the starting resource block of the first hop and the frequency hopping indication information. Specifically, referring to table 1, in the present embodiment,
number of physical resource blocks corresponding to initial upstream BWPThe minimum value of the number of physical resource blocks corresponding to the maximum bandwidth supported by the user equipment; frequency hopping indication information N UL，bop Resource block offset RB from second hop offse And correspond to each other.
As shown in Table 1, when
When N is present UL，bop The values of (a) may be: 0. 1. Accordingly, RB offse Can be that
(namely, to
1/2 rounding down) of,
(namely, to
1/4 rounding down). When in use
When N is present UL，bop The values of (a) may be: 00. 01, 10, 11. Accordingly, RB offse Can be that
And
for another example, before the UE feeds back the PUCCH to the base station, the base station may send the PUCCH resource mapping table to the UE in advance in a broadcast manner, and then use the time-frequency resource corresponding to the index value as the time-frequency resource for transmitting the PUCCH by indicating the index value of the PUCCH resource mapping table.
TABLE 2
In a specific implementation, as shown in table 2, the PUCCH resource mapping table may include Index value Index information, start OFDM symbol (First symbol) identification information corresponding to the Index value Index, and total time domain resource length (Number of symbols) information for transmitting the PUCCH corresponding to the Index value.
As shown in table 2, the PUCCH resource mapping table may further include: PUCCH format information PUCCH format corresponding to the Index value Index, resource block offset
And set information of an initial CS index value corresponding to the index value.
And step 32, determining a first resource and a second resource for transmitting the first data based on the resource configuration information, wherein the total bandwidth of the first resource and the second resource in the frequency domain is less than or equal to the maximum bandwidth supported by the user equipment.
In a specific implementation, for any first data, as long as receiving time domain resource configuration information and frequency domain resource configuration information sent by a base station, a user equipment may determine, based on the frequency domain resource configuration information, frequency domain resources used for transmitting the first data, so that a total bandwidth of the first resources and the second resources in a frequency domain is less than or equal to a maximum bandwidth supported by the user equipment, that is, a frequency interval between a first hop of the first data and a second hop of the first data is located within an initial uplink BWP.
In the embodiment of the present invention, the first resource may be understood as a time-frequency resource occupied by one hop of the first data. The second resource may be a time-frequency resource occupied by another hop of the first data.
When the first resource is a time-frequency resource occupied by a first hop of the first data and the second resource is a time-frequency resource occupied by a second hop of the first data, the total bandwidth of the first resource and the second resource in the frequency domain refers to a frequency domain resource between a frequency domain starting position of the first resource and a frequency domain ending position of the second resource. When the first resource is a time-frequency resource occupied by the second hop of the first data, and the second resource is a time-frequency resource occupied by the first hop of the first data, the total bandwidth of the first resource and the second resource in the frequency domain refers to a frequency domain resource from the frequency domain starting position of the second resource to the frequency domain ending position of the first resource. In this embodiment of the present invention, the total bandwidth of the first resource and the second resource in the frequency domain is also referred to as a resource span between the first resource and the second resource, that is, a resource span between two-hop resources of the first data.
In an implementation, the ue may determine how to determine the time domain resource and the frequency domain resource for frequency hopping transmission of the first data based on the indication of the base station. Of course, the ue may also determine how to determine the time domain resource and the frequency domain resource for frequency hopping transmission of the first data. For example, the user equipment may determine the time domain resource and the frequency domain resource for frequency hopping transmission of the first data by using the data transmission method in the embodiment of the present invention when detecting that the resource span between two hop resources configured by the base station for the UE to transmit the first data exceeds the maximum bandwidth that can be supported by the UE in the resource configuration information. If the user equipment detects that the resource span between two-hop resources configured by the base station for the UE to transmit the first data does not exceed the maximum bandwidth supported by the UE in the resource configuration information, the UE may transmit the first data according to the configuration of the base station without performing additional adjustment on the two-hop resources.
The resource span between two hops of resources for transmitting the first data does not exceed the maximum bandwidth that can be supported by the UE, for example, the initial uplink BWP includes 270 PRBs, the starting RB is 1, the number of RBs that can be continuously used is 2, and the RBs used in the first hop are RB1 and RB 2. SCS 15kHz, when N UL，hop At 00, the second hop uses the 136 th (1+270/2) and 137 th RBs according to the protocol's present method. With the scheme of the present invention, as shown in fig. 5, 54(1+106/2) th and 55 th RBs used by the second hop. The resource span between the 1 st RB (i.e., RB1) to the 55 th RB is less than the maximum bandwidth supported by the UE.
In one embodiment, when the second step isWhen the first data is PUSCH, for example, referring to table 1, the frequency domain resource allocation information of radio resource control connection request Msg3 includes: frequency hopping indication information N UL，bop . Frequency hopping removal indication information N UL，bop In addition, the frequency domain resource configuration information further includes: resource Indication Value (RIV). According to the RIV and the bandwidth of the initial UL BWP, the numerical value of the sequence number RBstart of the initial resource block in the continuous resource blocks used by the UE for transmitting uplink and the number of the continuous resource blocks used by the UE can be determined.
Specifically, when determining the frequency domain resource for transmitting the first data, a value of a starting resource block RBstart in consecutive resource blocks used by the UE for uplink transmission and a number L of consecutive resource blocks used by the UE may be determined based on an RIV configured by the base station. RBstart (0) is the starting frequency domain position information of the first resource, and the frequency domain resource corresponding to the first resource is RBstart (0), RBstart (0) +1, … … RBstart (0) + L.
For another example, the frequency domain configuration information of the first message MsgA is frequency startmsga-PUSCH, nrofPRBs-perMsgA-PO and MsgA-HoppingBits, RBstart can be obtained through frequency startmsga-PUSCH, nrofPRBs-perMsgA-PO is the number of consecutive PRBs available for the UE, and MsgA-HoppingBits corresponds to N in table 1 UL，hop 。
Determining initial frequency domain position information of a second resource of the first data based on the initial frequency domain position information of the first resource of the first data and the frequency hopping indication information, and then determining frequency domain positions corresponding to the first resource and the second resource of the first data based on the initial frequency domain position information of the first resource of the first data, the initial frequency domain position information of the second resource of the first data and the frequency domain resource length information for transmitting the first data, wherein the total bandwidth of the first resource and the second resource in the frequency domain is less than or equal to the maximum bandwidth supported by user equipment.
In a specific implementation, the starting frequency domain position of the second resource of the first data is a sum of the starting frequency domain position of the first resource of the first data and a preset corresponding frequency domain offset value. Can be specifically adoptedDetermining a starting resource block, RB, for the second resource using equation (1) start (1)：
RB start (1)＝RB start (0)+RB offse1 (1)
Wherein RB start (0) A starting resource block identification for the first resource.

It should be noted that, in the embodiment of the present invention, unlike the prior art, the following are: when N is present UL，hop When the value of (1) is 11, in order to simplify the formula and make the frequency interval between two adjacent hops of the first data smaller than

After the initial resource blocks of the first resource and the second resource are determined, the specific resource positions occupied by the first resource and the second resource can be determined based on the number of the continuous PRBs respectively usable by the first resource and the second resource which are configured in advance by the base station.
In another embodiment of the present invention, when the first data is the PUCCH, referring to table 2, frequency domain resource configuration information corresponding to an index value indicated in a preset PUCCH resource mapping table is used as the frequency domain resource configuration information. At this time, the preset PUCCH resource mapping table includes: index value information, resource block offset

For example, when Index is 0, r PUCCH ＝7，
Then, the first data first hop starting physical resource block is:
the second-hop starting physical resource block is:
the resource span between the first data two hops is within the maximum bandwidth supported by the UE.
In another embodiment of the present invention, when the first data is the PUCCH, referring to table 2, a frequency domain resource corresponding to an index value indicated in a preset PUCCH resource mapping table is used as frequency domain resource configuration information. At this time, the preset PUCCH resource mapping table includes: index value information, resource block offsetQuantity of

by changing the frequency domain resources used by the first hop and the second hop of the first data, the resource span between the first hop of the first data and the second hop of the first data is positioned at the maximum bandwidth supported by the UE, and the time domain resources configured by the base station are kept unchanged, thereby avoiding the user equipment from performing radio frequency modulation.
In a specific implementation, when the first data is PUSCH, assuming that a total length of time domain resources configured by a base station for transmitting the first data is L OFDM symbols, where L is less than or equal to 14, in a general case, the first data is PUSCH
One OFDM symbol is a time domain resource used by a first hop of the first data, and the remaining OFDM symbols are time domain resources used by a second hop of the first data.
When the first data is the PUCCH, referring to table 2, when Index is 1, the starting OFDM symbol of the time domain resource used by the first data is the 12 th OFDM symbol, and the length of the time domain resource used for transmitting the PUCCH is 2 OFDM symbols. Specifically, the 12 th OFDM symbol may be used as a time domain resource used by the first hop of the first data, and the 13 th OFDM symbol may be used as a time domain resource used by the second hop of the first data.
And after the configured time domain resource and the adjusted frequency domain resource are determined, transmitting the first data.
As can be seen from the above, in the data transmission method in the embodiment of the present invention, when determining the frequency domain resource for transmitting the first data based on the frequency domain resource configuration information, since the total bandwidth of the first resource for transmitting the first data and the second resource for transmitting the first data in the frequency domain is less than or equal to the maximum bandwidth supported by the user equipment, that is, the frequency interval between two adjacent hops is within the maximum bandwidth supported by the user equipment, the user equipment can transmit data without performing radio frequency modulation, and thus, data transmission by hopping in a time slot is completed.

Referring to fig. 6, an embodiment of the present invention further provides another data transmission method, where the method may include the following steps:
When the first data is PUSCH, the time domain resource configuration information of the first data may include identification information of a starting OFDM symbol in which the first data is transmitted, and a total length of time domain resources.
Accordingly, the frequency domain resource configuration information of the first data may include: the total length of the frequency domain resources, the identification information of the starting resource block of the first hop and the frequency hopping indication information. Referring specifically to table 3, in this embodiment,
indicates the number of physical resource blocks corresponding to the initial uplink BWP. Frequency hopping indication information N UL，bop Resource block offset RB from second hop offse1 And correspond to each other.

1/2 rounding down) of,
(i.e. to

When, N ULhop The values of (a) may be: 00. 01, 10, 11. Accordingly, RB offse1 Can be made of
And a Reserved value (Reserved).
In another embodiment, before the UE feeds back the PUCCH to the base station, the base station may send the PUCCH resource mapping table to the UE in advance in a broadcast manner, and then use the time-frequency resource corresponding to the index value as the time-frequency resource for transmitting the PUCCH by indicating the index value of the PUCCH resource mapping table.
Accordingly, the frequency domain resource configuration information includes: resource block offset
And set information of initial CS index values corresponding to the index values, as shown in table 4.
TABLE 4
In a specific implementation, after obtaining the resource configuration information, the UE may first determine whether the resource span between two hops of the first data exceeds the maximum bandwidth supported by the UE according to the configuration of the base station. When the resource span between two hops of the first data exceeds the maximum bandwidth supported by the UE, the data transmission method described in embodiment 2 is adopted to determine the first resource and the second resource of the first data, otherwise, the first resource and the second resource are determined according to the existing 3GPP protocol requirements.
In a specific implementation, in order to enable an interval between the first resource and the second resource in the time domain to be greater than or equal to a duration for performing radio frequency modulation, a time domain resource length configured by the resource configuration information is greater than or equal to a sum of the time domain resource length for performing radio frequency modulation and a time domain resource length for transmitting a PUCCH. The first resource may be a time-frequency resource occupied by a first hop of the first data, and correspondingly, the second resource may be a time-frequency resource occupied by a second hop of the first data. Of course, the first resource may also be a time-frequency resource occupied by the second hop of the first data, and the second resource may also be a time-frequency resource occupied by the first hop of the first data.
At this time, a part of time domain resources configured by the time domain resource configuration information are used for radio frequency modulation between frequency hopping of the frequency domain, and the rest of the time domain resources are used as time domain resources for actually transmitting the first data, so that the radio frequency modulation can be performed on the basis of continuous time domain resources between two hops configured by the base station, and the frequency modulation transmission is completed.
It should be noted that, in practical applications, the length of the time domain resource required by the radio frequency modulation may be predetermined by a protocol or other manners. The base station may also acquire in other manners. And the base station determines the initial resource block of the time domain resource and the time domain resource length actually used for transmitting the PUCCH based on the time domain resource length required by the radio frequency modulation.
In a specific implementation, when the time domain resource configuration information configured by the base station for transmitting the first data includes the start symbol identifier information for transmitting the first data and the total length of the time domain resources, the time domain resource length for transmitting the first data may be determined in combination with the time domain resource length required by the radio frequency modulation.
Suppose that the total length of time domain resources configured by the base station for transmitting the first data is L OFDM symbols, and L is less than or equal to 14. The length of the time domain resource required for performing radio frequency modulation is x OFDM symbols, the length of the time domain resource occupied by the first hop and the second hop of the first data is L-x, namely the length of the residual time domain resource is L-x. Dividing the length of the residual time domain resources into L-x residual time domain resources and second residual time domain resources, wherein the time domain position of the first hop of the first data is the time domain resource occupied by the first residual time domain resource, and the time domain position of the second hop of the first data is the time domain resource occupied by the second residual time domain resource. And the transmission ending time of the first jump of the first data is the starting time of the radio frequency modulation. And the ending time of the radio frequency modulation, namely the starting time of the second hop transmission of the first data.
In an embodiment of the present invention, a time domain resource occupied by a first hop of the first data may be equal to a time domain resource occupied by a second hop of the first data, that is, a length of a first remaining time domain resource is equal to a length of a second remaining time domain resource. Of course, in other embodiments, the lengths of the first remaining time domain resource and the second remaining time domain resource may be different.
Referring to fig. 7, when L is 6 and x is 2, the lengths of the first remaining time domain resource and the second remaining time domain resource are (L-x)/2 is 2, where the time domain resource used by the first data first hop is the 1 st OFDM symbol and the 2 nd OFDM symbol, the time domain resource used by the first data second hop is the 5 th OFDM symbol and the 6 th OFDM symbol, and the time domain resource used by the radio frequency modulation is the 3rd OFDM symbol and the 4 th OFDM symbol.
When the interval between the first resource and the second resource in the time domain is greater than or equal to the duration for the frequency modulation of the radio frequency, the frequency domain resource for transmitting the first data may be determined accordingly by using the following two schemes.
Scheme 1: the frequency domain resource configuration information of the first data may include: the total length of the frequency domain resources, the identification information of the initial resource block of the first hop and the frequency hopping indication information. See table 3 for details.
In conjunction with table 3, the following equation (2) may be adopted to determine the starting resource block RB of the second hop start (1)：
Wherein RB start (0) Is identified for the starting resource block of the first hop,
for example, when
N UL，bop ＝00，RB start 120, then the starting RB of the first hop start (0) For 120 th RB, start of second hop
I.e. the starting resource block of the second hop is the 40 th RB.
Scheme 2: the frequency domain resource configuration information includes: resource block offset
And set information of initial CS index values corresponding to the index values, as shown in table 4.
At this time, in the first resource and the second resource for transmitting the first data, the start of the frequency domain resource of the first resource
Initiation of frequency domain resources of a second resource
Or start of frequency domain resource of second resource
Wherein, the first and the second end of the pipe are connected with each other,
determines whether the first hop or the second hop is used
r PUCCH Determined by the configuration of the base station, r PUCCH And
and N CB For determining the frequency domain resource of PUCCH transmission, refer to the definition of 38.213-g 309.2.1.
And N CS The decision may be based on the index of the base station configuration of table 4.
In a specific implementation, the base station may introduce a signaling in a system message (SIB) to indicate whether to use embodiment 1 or embodiment 2. When the base station indicates to use the embodiment 2, the user equipment transmits the first data by adopting the embodiment 2 frequency hopping. User equipment embodiment 1 frequency hopping transmits said first data when the base station instructs to use embodiment 1. In the embodiment of the present invention, the frequency hopping in the time slot is described as an example of two hops. It can be understood that the frequency hopping in the time slot may also be more than three hops, and the data transmission method in the embodiment of the present invention may be used to perform frequency hopping transmission regardless of the frequency hopping times.
It should be noted that the data transmission method in the embodiment of the present invention is not only applicable to frequency hopping transmission in a time slot during a random access process, but also applicable to frequency hopping transmission in a time slot in other scenarios, and is not limited herein.
As can be seen from the above, in the data transmission method in the embodiment of the present invention, when data needs to be frequency hopped and transmitted in a time slot, radio frequency modulation between frequency hopping is performed on a part of time domain resources configured by the time domain resource configuration information, and the remaining part of time domain resources are used as time domain resources for transmitting first data, and frequency hopping is performed to transmit the first data by using the frequency domain resources configured by the frequency domain resource configuration information, so that not only can time continuity between two adjacent frequency hopping be ensured, but also a certain time can be used for radio frequency modulation, thereby completing data transmission requiring frequency hopping in the time slot.
