Description

Method for determining resources, resource allocation method and device

This invention is a divisional application of the invention patent application with application number 201711140825.3 and invention name “method for determining resources, resource allocation method and device”

Technical Field

The present invention relates to the field of wireless communication technology, and in particular to a method for determining resources, a method for configuring resources, and a device.

Background technique

With the rapid development of the information industry, especially the growing demand from mobile Internet and Internet of Things (IoT), future mobile communication technology has brought unprecedented challenges. For example, according to the report ITU-R M.[IMT.BEYOND 2020.TRAFFIC] of the International Telecommunication Union, it can be expected that by 2020, the growth of mobile business volume will increase by nearly 1,000 times compared with 2010 (4G era), and the number of user device connections will exceed 17 billion. As a large number of IoT devices gradually penetrate into mobile communication networks, the number of connected devices will be even more amazing. In order to cope with this unprecedented challenge, the communications industry and academia have launched extensive research on the fifth generation of mobile communication technology (5G) for the 2020s. At present, the framework and overall goals of the future 5G are being discussed in the ITU report ITU-R M.[IMT.VISION], which provides a detailed description of the demand outlook, application scenarios and various important performance indicators of 5G. In response to new requirements in 5G, the ITU report ITU-R M.[IMT.FUTURE TECHNOLOGY TRENDS] provides information on technology trends for 5G, aiming to address significant issues such as significant improvement in system throughput, consistency in user experience, scalability to support IoT, latency, energy efficiency, cost, network flexibility, support for emerging services, and flexible spectrum utilization.

The performance of random access directly affects the user experience. In traditional wireless communication systems, such as LTE and LTE-Advanced, the random access process is applied to multiple scenarios such as establishing an initial link, cell switching, reestablishing an uplink link, and reestablishing an RRC connection. It is divided into contention-based random access and contention-free random access according to whether the user has exclusive use of the preamble sequence resources. In contention-based random access, each user device selects a preamble sequence from the same preamble sequence resource when trying to establish an uplink link. Multiple user devices may select the same preamble sequence to send to the network device. Therefore, the conflict resolution mechanism is an important research direction in random access. How to reduce the probability of conflict and how to quickly resolve conflicts that have occurred are key indicators that affect the performance of random access.

The contention-based random access process in LTE-A is divided into four steps, as shown in Figure 1. In the first step, the user equipment randomly selects a preamble sequence from the preamble sequence resource pool and sends it to the network device. The network device performs correlation detection on the received signal to identify the preamble sequence sent by the user equipment; in the second step, the network device sends a random access response (RAR) to the user equipment, including a random access preamble sequence identifier, a timing advance instruction determined based on the delay estimation between the user equipment and the network device, a temporary cell radio network temporary identifier (Cell-Radio Network Temporary Identifier, C-RNTI), and the time-frequency resources allocated for the next uplink transmission of the user equipment; in the third step, the user equipment sends a third message (Msg3) to the network device based on the information in the RAR. Msg3 contains information such as the user equipment identifier and the RRC connection request, where the user equipment identifier is unique to the user and is used to resolve conflicts; in the fourth step, the network device sends a conflict resolution identifier to the user equipment, including the identifier of the user equipment that wins the conflict resolution. After detecting its own identity, the user equipment upgrades the temporary C-RNTI to C-RNTI, sends an ACK signal to the network device, completes the random access process, and waits for the scheduling of the network device. Otherwise, the user equipment will start a new random access process after a delay.

For the non-competition-based random access process, since the network device knows the user equipment identifier, it can allocate a preamble sequence to the user equipment. Therefore, when the user equipment sends the preamble sequence, it does not need to randomly select a sequence, but will use the allocated preamble sequence. After detecting the allocated preamble sequence, the network device will send a corresponding random access response, including information such as timing advance and uplink resource allocation. After receiving the random access response, the user equipment considers that the uplink synchronization has been completed and waits for further scheduling by the network device. Therefore, the non-competition-based random access process only includes two steps: step one is to send the preamble sequence; step two is to send the random access response.

The random access procedure in LTE is applicable to the following scenarios:

1. Initial access under RRC_IDLE;

2. Re-establish the RRC connection;

3. Cell switching;

4. Downlink data arrives in RRC connected state and requests random access process (when uplink is asynchronous);

5. Uplink data arrives in RRC connected state and requests random access process (when the uplink is in asynchronous state or no resources are allocated to the scheduling request in the PUCCH resources);

6. Positioning.

In LTE, the above six scenarios use the same random access procedure.

Before the random access process, the UE needs to determine the available random access resources. However, in the new communication system, the bandwidth is divided into one or more different frequency band parts (BWP). Therefore, how the user equipment determines the available random access resources for random access becomes a difficult problem for those skilled in the art.

In a new communication system, network equipment (e.g., base stations, access point equipment) will divide a bandwidth into one or more different frequency band parts (BWP). Therefore, at the time of initial access, the network equipment needs to notify the user of the frequency band part information used for initial access and the location information of random access resources. Therefore, how the network equipment notifies the user equipment of the frequency band part information used for initial access and the location information of random access resources so that the user equipment can determine the location information of random access resources for initial access becomes a difficult problem for those skilled in the art.

For a new system, there may be multiple available uplink frequency band parts (Uplink BWP, UL BWP), and at the time of initial access, the user equipment does not obtain the configuration of the frequency band part in the network, nor does it obtain the configuration of the random access resources in the network, so it cannot access the network normally. The network equipment needs to notify the user equipment of the configuration of the uplink frequency band part and the random access resources. The network equipment jointly notifies the user of the configuration information of the initial uplink frequency band part and the frequency domain location information of the random access resources. After obtaining the configuration information of the initial uplink frequency band part and the frequency domain location information of the random access resources, the user equipment can find the location of the available random access resources.

Based on the above technical problems to be solved, an embodiment of the present invention provides a resource configuration method. Specifically, an embodiment of the present invention provides a resource configuration method, as shown in FIG2, including: step 210, configuring an initially activated uplink frequency band portion and corresponding random access resources; step 220, sending configuration information of the initially activated uplink frequency band portion and corresponding random access resources to a UE for the UE to perform random access.

The resource configuration method provided in the embodiment of the present invention configures the initial activation uplink frequency band part and the corresponding random access resources, provides a prerequisite for subsequently sending the configuration information of the initial activation uplink frequency band part and the corresponding random access resources to the UE, sends the configuration information of the initial activation uplink frequency band part and the corresponding random access resources to the UE for the UE to perform random access, thereby notifying the user of the frequency band part information used for the initial access and the location information of the random access resources, so that the user can obtain the configuration of the initial activation uplink frequency band part and the corresponding random access resources in time during the initial access and access the network normally.

Preferably, the method for configuring the initial activation of the uplink frequency band part includes any one of the following: configuring the indication information of the frequency domain starting position and the bandwidth indication information of the initial activation of the uplink frequency band part; configuring the indication information of the frequency domain starting position of the initial activation of the uplink frequency band part; configuring the indication information of the bandwidth of the initial activation of the uplink frequency band part; configuring the index indicating the initial activation of the uplink frequency band part.

Preferably, configuring the indication information of the frequency domain starting position of the initially activated uplink frequency band part and/or the indication information of the bandwidth includes any one of the following methods: configuring an index indicating the frequency domain starting position of the initially activated uplink frequency band part and/or an index indicating the bandwidth of the initially activated uplink frequency band part; configuring an index indicating the combination of the frequency domain starting position of the initially activated uplink frequency band part and the bandwidth of the initially activated uplink frequency band part.

Preferably, the method for configuring random access resources includes any one of the following: configuring indication information of the frequency domain position of the first random access channel and indication information of the offset between adjacent random access channels; configuring indication information of the frequency domain position of the first random access channel; configuring indication information of the offset between adjacent random access channels.

Preferably, the method for configuring the indication information of the frequency domain position of the first random access channel includes any one of the following: configuring the indication information of the offset between the frequency domain starting position of the first random access channel and the frequency domain starting position of the initially activated uplink frequency band part; configuring the indication information of the frequency domain starting position of the first random access channel in the initially activated uplink frequency band part; configuring the indication information of the frequency domain starting position of the first random access channel in the entire frequency band.

Preferably, the frequency domain position of the random access channel satisfies a symmetric frequency hopping rule.

Preferably, it also includes: configuring a beam failure recovery request resource corresponding to the random access resource; and sending configuration information of the beam failure recovery request resource corresponding to the random access resource to the UE.

Preferably, configuring the beam failure recovery request resource corresponding to the random access resource includes at least one of the following methods: configuring the indication information of the frequency domain interval between the first beam failure recovery request resource and the frequency domain end position of the last random access channel; configuring the indication information of the frequency domain interval between adjacent beam failure recovery request resources; configuring the indication information of the frequency domain interval between any beam failure recovery request resource and the adjacent random access channel, and the indication information of the frequency domain interval between adjacent random access channels.

Specifically, in an embodiment of the present invention, the network device will divide the available uplink frequency domain resources into a plurality of different frequency band parts, wherein each frequency band part is identified by an absolute physical resource block (PRB) index, as shown in FIG3 . The first frequency band part starts from PRB index 0 to PRB index 99, the second frequency band part starts from PRB index 100 to PRB index 199, and so on. Among them, the network device can pre-configure the number of PRBs occupied by each frequency band part, and the bandwidth occupied by each frequency band part (i.e., the number of PRBs occupied) can be different. At the time of initial access, the user equipment has not yet accessed the system, so it has not obtained the frequency band setting in the system, so it may not be able to find the initial active uplink frequency band part (initial active UL BWP), and it may not be able to determine the location of the random access resources available in the system. Therefore, in an embodiment of the present invention, the network device in the system information:

● Notify the starting position and bandwidth (number of PRBs or bandwidth, etc.) of the initial activation of the uplink frequency band;

●Notify the starting position of the initial activation uplink frequency band portion, and the bandwidth of the initial activation uplink frequency band portion is pre-set;

●Notify the bandwidth of the initially activated uplink frequency band portion, and the starting position of the initially activated uplink frequency band portion is pre-set;

●The starting position of the initially activated uplink frequency band portion and the bandwidth of the frequency band portion are both pre-set.

At the same time, according to the starting position of the configured initial activated uplink frequency band part, the frequency domain position of the corresponding random access channel is notified:

● Random access channels are placed continuously, notifying the offset between the frequency domain starting point of the first random access channel and the starting point of the initially activated uplink frequency band portion;

● The random access channels are placed non-continuously, notifying the offset between the frequency domain starting point of the first random access channel and the starting point of the initially activated uplink frequency band portion, and notifying the frequency domain offset of two adjacent random access channels.

The user equipment determines the position of the initial activated uplink frequency band part according to the configuration information of the initial activated uplink frequency band part obtained in the system information, and determines the frequency domain starting position of the available random access channel in combination with the configuration information of the random access channel.

The above embodiments of the present invention are fully and thoroughly described below through the following preferred implementations:

Embodiment 1:

In the first embodiment, it will be described how the user equipment (UE) obtains the initial activation uplink frequency band portion and the available random access channel frequency domain position through the configuration information of the network device. In the present invention, the frequency domain position is represented by a frequency domain resource unit index, or one or more frequency domain resource unit intervals, where the frequency domain resource unit can be a subcarrier, a subcarrier group, a physical resource block (PRB), a physical resource block group (PRB group), etc. In the description of the first embodiment, for simplicity, the physical resource block PRB is used as the frequency domain resource unit for description.

First, at the time of initial access, the UE can search for a synchronization signal block (SS block) signal from a cell, find the system information configured by the network device by successfully reading the broadcast message in the SS block, and obtain the configuration information of the initial activation uplink frequency band part in the system information, that is, receive the configuration information of the initial activation uplink frequency band part in the system information, including:

● Read the PRB index and bandwidth of the initial activated uplink frequency band directly configured by the network device. The specific methods are as follows:

○ Directly use N bits to indicate the PRB index and bandwidth. For example, 9 bits are used in the system information to configure the PRBindex=200 of the frequency domain starting position of the initial activation of the uplink frequency band part, and the bandwidth indicated by the 9 bits is 100 PRBs, as shown in Figure 3, indicating that the initial activation of the uplink frequency band part starts from the 200th PRB of the uplink bandwidth of the entire system and occupies 100 PRB bandwidth.

○ The UE receives indication information from the network device for indicating the frequency domain starting position of the initially activated uplink frequency band portion, wherein the indication information is in the form of an index. The PRB index is directly indicated by N bits, or the N-bit index is used to indicate multiple possible PRB indexes in a table lookup manner, and the bandwidth size is directly indicated by M bits, or the M-bit index is used to indicate in a table lookup manner. For example, four possible PRB indexes are indicated by N=2 bits, as shown in Table 1, and the 2 bits respectively indicate possible PRB indexes: 0, 100, 200, and 300.

Table 1 Example of PRB index indication of the frequency domain starting position of the initial activation uplink frequency band part

Bit value PRB index of the frequency domain starting position 00 0 01 100 10 200 11 300

Similarly, four possible bandwidths are indicated by M=2 bits, as shown in Table 2, where the 2 bits respectively indicate possible bandwidths of: 50 PRBs, 100 PRBs, 150 PRBs, and 200 PRBs.

Table 2 Example of bandwidth indication for initially activated uplink frequency band portion

In addition, the PRB index of the frequency domain starting position of the initially activated uplink frequency band part and the bandwidth occupied by the frequency domain may be jointly indicated using an N-bit index, as shown in Table 3.

N=2 bits are used to indicate four possible combinations of PRB index and bandwidth occupied by the frequency domain. Table 3 Example of PRB index and bandwidth occupied by the frequency domain for the initial activation of the uplink frequency band portion

●Specially, the PRBindex of the frequency domain starting position of the initial activated uplink frequency band part directly configured by the network is read, but the bandwidth of the initial activated uplink frequency band part is preset. For example, the network device presets the bandwidth of the initial activated uplink frequency band part to 100 PRBs, and the PRB index is notified by the above possible methods, which will not be repeated.

●Specially, the bandwidth of the frequency band portion of the initial activated uplink frequency band portion directly configured by the network device is read, but the PRB index of the frequency domain starting position of the initial activated uplink frequency band portion is preset by the network. For example, the network device presets the PRBindex of the initial activated uplink frequency band portion to be calculated starting from the 200th PRB, and the bandwidth (i.e., the number of PRBs occupied) is notified by the above possible methods, which will not be repeated.

●Specially, the PRB index and bandwidth of the initially activated uplink frequency band part are both preset. For example, the PRB index of the frequency domain start position of the initially activated uplink frequency band part is preset to be calculated starting from the 200th PRB, and the bandwidth is preset to be 100 PRBs.

● Read the index of the initially activated uplink frequency band part configured by the network device. At this time, all or part of the configuration information of the possible uplink frequency band parts (starting PRB index and/or corresponding frequency band part bandwidth) is notified to the user equipment in a preset manner or in a system message, and each possible uplink frequency band part corresponds to an uplink frequency band part index. At the same time, the index of the initially activated uplink frequency band part (UL BWPindex) is notified to the user equipment in the system message, which can be notified by directly using an N-bit index, or the N-bit index is notified by table lookup, as shown in Table 4, N=2 bits notify 4 possible BWP indices as the initially activated uplink frequency band part.

Table 4 Example of BWP index for initially activated uplink frequency band portion

Bit value UL BWP Index 00 0 01 1 10 2 11 3

After the UE obtains the configuration information of the initial activated uplink frequency band part configured by the network device, the starting position and/or bandwidth of the initial activated uplink frequency band part is determined according to the configuration information. Therefore, according to the configuration of the initial activated uplink frequency band part that has been determined and the random access resource configuration information notified in the system information, the frequency domain positions of M (M>=1) available random access channels are determined, and initial access is performed according to the random access channel at the frequency domain position, specifically:

■When M random access channel resources are continuous:

●The frequency domain starting position of the first random access channel is preset to be the Xth PRB or X PRBs away from the starting position of the initially activated uplink frequency band portion.

★X is the offset from the starting position of the initially activated uplink frequency band portion; for example, X=2, indicating that the frequency domain starting position of the first available random access channel is 2 PRBs after the starting position of the initially activated uplink frequency band portion.

★Specially, X=0, which means that the frequency domain starting position of the first available random access channel starts from the starting position of the initially activated uplink frequency band.

●The UE receives the offset between the frequency domain starting position of the first random access channel configured by the network device and the starting position of the initially activated uplink frequency band part. The offset configuration method is shown in Figure 3. For example, the network device configures the first available random access channel to be offset by 3 PRBs from the starting position of the initially activated uplink frequency band part, indicating that the frequency domain starting position of the first available random access channel is 3 PRBs after the starting position of the initially activated uplink frequency band part. In particular, N bits can be used to directly indicate the offset, or N bits can be used to look up the table to indicate the offset, which is similar to the above-mentioned table lookup method and will not be repeated.

●UE reads the frequency domain starting position of the first random access channel configured by the network device in the initially activated uplink frequency band part, such as the Xth PRB of the initially activated uplink frequency band part. For example, the network device configures the first available random access channel in the 3rd PRB of the initially activated uplink frequency band part. In particular, N bits can be used to directly indicate the value of X, or the value of X can be indicated by using an N-bit table lookup method, which is similar to the above table lookup method and will not be repeated here.

●UE reads the frequency domain starting position of the first random access channel configured by the network device in the whole frequency band, such as the Xth PRB of the whole frequency band. For example, the network device configures the first available random access channel in the 303rd PRB of the whole frequency band. In particular, N bits can be used to directly indicate the value of X, or the value of X can be indicated by using an N-bit table lookup method, which is similar to the above table lookup method and will not be repeated.

■When the M random access channel resources are discontinuous:

● The network device configures or presets the frequency domain starting position of the first random access channel to be the Xth PRB of the initially activated uplink frequency band part, or the Xth PRB of the full frequency band part, or the X PRBs away from the starting position of the initially activated uplink frequency band part; then for other random access channels, there are:

★UE reads the interval bandwidth Y PRBs configured or preset by the network device. As shown in Figure 5, the UE finds the frequency domain starting point of the first random access channel through the preset X value, and then determines the position of the remaining random access channels through the configured interval bandwidth Y of the adjacent random access channels. The value of Y can be notified directly by N bits or by a table lookup method of N bits. The table lookup method is similar to the above table lookup method and will not be repeated.

●UE determines the frequency domain positions of the remaining random access channels according to the symmetrical frequency hopping rules configured by the network equipment; as shown in Figure 6. After the UE determines the first random access channel, it symmetrically finds the second random access channel with the center position of the initially activated uplink frequency band as the axis. The frequency domain end position of the random access channel is also X PRBs away from the end position of the initially activated uplink frequency band. The starting position of the third random access channel is Y PRBs away from the end position of the first random access channel. Similarly, the starting position of the fourth random access channel is also determined by the frequency hopping rules. In particular, Y can be 0.

★Specially, the interval bandwidth in the frequency domain is pre-set to be X PRBs, or the network device configures the interval bandwidth in the frequency domain to be X PRBs; that is, the first random access channel is X PRBs away from the starting position of the initially activated uplink frequency band part, and the frequency domain interval of the adjacent random access channels is also X PRBs, as shown in Figure 7. Specially, the above-mentioned frequency hopping rule can also be used to determine other random access channels except the first random access channel, that is, after the UE determines the first random access channel, it takes the center position of the initially activated uplink frequency band part as the axis and symmetrically finds the second random access channel. The frequency domain end position of the random access channel is also X PRBs away from the end position of the initially activated uplink frequency band part. The starting position of the third random access channel is after the end position of the first random access channel is separated by Y PRBs. Similarly, the starting position of the fourth random access channel is also determined by the frequency hopping rule.

★Specially, X=0; that is, the network device presets the first random access channel to start from the starting position of the initially activated uplink frequency band portion, and then the remaining random access channels are confirmed according to the interval of Y PRBs between adjacent random access channels, as shown in Figure 8. Specially, the above-mentioned frequency hopping rule can also be used to determine other random access channels except the first random access channel, that is, after the UE determines the first random access channel, it takes the center position of the initially activated uplink frequency band portion as the axis and symmetrically finds the second random access channel. The frequency domain end position of the random access channel is also X PRBs away from the end position of the initially activated uplink frequency band portion. The starting position of the third random access channel is after the interval of Y PRBs from the end position of the first random access channel. Similarly, the starting position of the fourth random access channel is also determined by the frequency hopping rule.

Embodiment 2:

In the second embodiment of the present invention, it will be introduced that the UE determines possible resources for beam failure recovery request through the determined random access channel resources and the beam failure recovery request resource information preset or configured by the network device.

Preferably, a similar method as in the previous embodiment can be used to obtain the frequency domain position of the initially activated uplink frequency band portion and the corresponding available beam failure recovery request resources through the configuration information of the network device, wherein the configuration method of the frequency domain position of the beam failure recovery request resources is the same as the configuration method of the frequency domain position of the above-mentioned random access resources, which will not be repeated here, and the time domain position of the available beam failure recovery request resources is the same as the time domain position of the available random access resources.

Preferably, the frequency domain position of the available beam failure recovery request resource can also be determined by the determined initial activated uplink frequency band part and the frequency domain position of the corresponding available random access channel resource, and the configured beam failure recovery request resource configuration information, wherein:

■When the determined M available random access channels are continuous:

●UE finds the first available beam failure recovery request resource by using the interval Z PRBs between the first beam failure recovery request resource preset or configured by the network device and the frequency domain end position of the last random access channel, as shown in Figure 9. For example, if the network device presets or configures X as 3PBR, and each random access channel occupies 6 PRBs, the network device configures 4 available continuous random access channel resources at this time, and the configured Z is 3 PRBs, then it means that the frequency domain position of the first available beam failure recovery request resource starts at the 30th PRB from the starting position of the initially activated uplink frequency band portion. The specific value of Z can be notified by N bits, or the configured Z value can be obtained by looking up a table through N bits. The table lookup method is similar to that described in the above embodiment and will not be repeated.

–Specially, Z can be preset or configured to be 0, indicating that the random access channel and the beam failure recovery request resource are continuous in the frequency domain.

●In addition, the UE can also determine the subsequent available beam failure recovery request channel by presetting or notifying the interval between two adjacent beam failure recovery request channels of D PRBs configured by the network device, as shown in Figure 9. For example, if the network device presets or configures D as 1 PRB, the end position of the frequency domain of the previous beam failure recovery request channel plus D=1 PRB is the starting position of the frequency domain of the next beam failure recovery request. The specific value of D can be notified by N bits, or the configured D value can be obtained by looking up the table through N bits. The table lookup method is similar to that described in the above embodiment and will not be repeated.

–Specially, D can be preset or configured to be 0, indicating that the available beam failure recovery request resources are continuous in the frequency domain.

■When the determined M available random access channels are non-contiguous:

●UE finds the first available beam failure recovery request resource by using the interval of Z PRBs between the first beam failure recovery request resource preset or notified by the network device configuration and the frequency domain end position of the last random access channel, as shown in Figure 10. For example, if the network device presets or configures X as 3PBR, there is a Y=1 PRB interval between every two adjacent random access channels, and each random access channel occupies 6 PRBs, the network device is now configured with 4 available continuous random access channel resources, and the configured Z is 3 PRBs, which means that the frequency domain position of the first available beam failure recovery request resource starts at the 33rd PRB from the starting position of the initially activated uplink frequency band portion. The specific value of Z can be notified by N bits, or the configured Z value can be obtained by looking up a table using N bits. The table lookup method is similar to that described in the above embodiment and will not be repeated.

– Specifically, Z can be preset or configured to be 0, indicating that the beam failure recovery request resource is immediately after the end of the random access access channel in the frequency domain.

●In addition, the UE can also determine the subsequent available beam failure recovery request channel by presetting or notifying the interval between two adjacent beam failure recovery request channels of D PRBs configured by the network device, as shown in Figure 10. For example, if the network device presets or configures D as 1 PRB, the frequency domain end position of the previous beam failure recovery request channel plus D = 1 PRB is the starting position of the frequency domain of the next beam failure recovery request. The specific value of D can be notified by N bits, or the configured D value can be obtained by looking up a table through N bits.

The table lookup method is similar to that described in the above embodiment and will not be described in detail.

–Specially, D can be preset or configured to be 0, indicating that the available beam failure recovery request resources are continuous in the frequency domain.

●Specially, in the above two methods, the frequency domain position of the beam failure recovery request resource is relatively determined by the position corresponding to the last random access channel. In the following method, the present invention proposes a method for determining the frequency domain position of a corresponding beam failure recovery request resource based on each random access channel alone, that is, the next adjacent random access channel and the next adjacent beam failure recovery request resource are preset or notified by the network device configuration to be Y PRBs and D PRBs respectively with the interval value of the random access channel. As shown in FIG11, when the user equipment confirms the position of the first random access channel (PRACH#1), according to the preset or network device configuration notification of Y=5 PRBs and D=1 PRBs, it is known that the frequency domain starting position of the corresponding beam failure recovery request resource (BFRQ#1) is after 1 PRB from the end position of the random access channel, and the frequency domain starting position of the corresponding next random access channel (PRACH#2) is after 5 PRBs from the end position of the random access channel.
