Detailed ways

In the 5th Generation New RAT (5G NR) mobile communication system, with the evolution of technology and the requirements of application scenarios, different types of terminals are defined one after another. For example, the 3rd Generation Partnership Project (3GPP) Rel-17 version protocol defines CE terminals (Terminal, also known as User Equipment (UE)), RedCap terminals, small data terminals, etc. Considering that the application scenarios and technologies used by the aforementioned terminals are all different, the identification of terminal types will be an important topic.

In the discussion of Rel-17, the identification technology for terminal types has been involved, and a typical method is to complete the identification of different terminal types in the initial access process.

For example, in the current 5G NR system, there are four-step random access (4-step Random Access, 4-step RA) and two-step random access (2-step Random Access, 2-step RA). A terminal with 2-step RA capability chooses to use 4-step RA or 2-step RA to initiate a random access procedure according to the current channel conditions. At this time, the terminal and the base station distinguish between 4-step RA and 2-step RA in two ways.

1. Through independent RACH configuration, that is, 4-step RA and 2-step RA occupy different time-frequency resources to send the preamble code.

2. Different types of terminals are distinguished by different Preamble indexes, that is, 4-step RA and 2-step RA send different Preamble indexes on the same time-frequency resource.

RACH resources are periodic resources and are configured at the cell level. Once configured, they always exist in the system. However, not every RACH resource has a random access (Random Access, RA) message sent. Since the network side does not know the actual occupancy of the RACH resources, in order to avoid interference to the RACH channel, all uplink resources cannot be used for uplink data transmission, resulting in waste of resources and reduced spectrum efficiency.

In addition, due to the need to ensure the transmission performance of the RACH, the base station needs to avoid the RACH resources when scheduling uplink transmission. When there are too many RACH resources in the system, the uplink transmission resources of the terminal will be fragmented, making the scheduling excessively complicated.

In view of the above technical problems, the embodiments of the present disclosure use different random access channel occasions (RACH occasion, RO) to distinguish different types of terminals, and different types of terminals send random access preambles in different ROs. The RO used to send the random access preamble determines the type of terminal.

In order to make the purposes, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments These are only some of the embodiments of the present disclosure, but not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present disclosure.

FIG. 1 is one of the schematic flow charts of an information transmission method provided by an embodiment of the present disclosure. As shown in FIG. 1 , an execution subject of an information transmission method provided by an embodiment of the present disclosure may be a terminal. The method includes:

Step 101: The terminal determines the target RO for sending the random access preamble according to its own type and the association between the random access channel opportunity RO and the terminal type.

Specifically, in the embodiment of the present disclosure, different ROs are used to distinguish different types of terminals, and different types of terminals send random access preambles in different ROs. RO determines the type of terminal.

First, the terminal needs to determine the association relationship between the RO and the terminal type.

On the one hand, the association relationship between the RO and the terminal type may be pre-configured through a protocol.

On the other hand, the association relationship between the RO and the terminal type can be configured by the network side.

The association relationship between the RO and the terminal type may be the corresponding relationship between the type number of the terminal and the SSB2RO mapping period or the number of the SSB2RO association period to which the RO that the terminal is allowed to use belongs. It may also be the correspondence between the bitmap of the terminal and the SSB2RO mapping period to which the RO that the terminal is allowed to use belongs, or the number of the SSB2RO associated period, or the like.

For example, the relationship between RO and terminal type is as follows:

The number of ROs allowed to be used by the terminal of type 1 is 1, the number of ROs allowed to be used by terminals of type 2 is 2, ..., and the number of ROs allowed to be used by terminals of type n is n.

For another example, the relationship between RO and terminal type is as follows:

The synchronization signal block to random access channel (synchronization signal block to RACH occasion, SSB2RO/SSB-to-RO) mapping cycle to which the RO that type 1 terminals are allowed to use is numbered 1, and type 2 The number of the SSB2RO mapping cycle to which the RO that the terminal is allowed to use is 2, ..., and the number of the SSB2RO mapping cycle to which the RO that the nth type of terminal is allowed to use belongs is n.

The number of the SSB2RO association period (association period) to which the terminal with type number 1 is allowed to use is 1, and the number of the SSB2RO association period to which the terminal with type number 2 is allowed to use is 2, ..., type number The number of the SSB2RO association period to which the terminal n is allowed to use belongs is n.

For another example, the relationship between RO and terminal type is expressed by the formula as follows:

m=mod(n _cycle ,M)+n

Among them, m is the type number/identification code of the terminal; M is the number of types of terminals that need to be distinguished; n _cycle is the SSB2RO mapping cycle or the number/identification code of the SSB2RO association period to which the mth type of terminal is allowed to use the RO, and n is a natural number.

It should be noted that the above examples of the association relationship between the RO and the terminal type are not exhaustive, and other similar association relationships are also feasible, which will not be repeated here.

After the terminal determines the association relationship between the RO and the terminal type, if random access is required, it determines the target RO for sending the random access preamble according to its own type and the association relationship between the RO and the terminal type.

For example, the association relationship between RO and terminal type is: N1 SSB-to-RO mapping cycles in C association periods are used for random access of CE UEs; N2 SSB-to-RO mapping cycles are used for random access of RedCap UEs Access; N3 SSB-to-RO mapping cycles are used for random access of small data, and so on. Different types of terminals send the Preamble code on the RO included in the corresponding SSB-to-RO mapping cycle.

Among them, N1 SSB-to-RO mapping cycles, N2 SSB-to-RO mapping cycles, and N3 SSB-to-RO mapping cycles do not overlap each other. N1+N2+N3+...+Nn<=sum of cycles included in C association periods, C, N1, N2, N3...Nn are all integers greater than or equal to 1.

When the CE UE performs random access, it uses the RO included in the N1 SSB-to-RO mapping cycles to send the Preamble code. When performing random access, the RedCap UE uses the RO included in the N2 SSB-to-RO mapping cycles to send the Preamble code. When the small data UE performs random access, it uses the RO included in the N3 SSB-to-RO mapping cycles to send the Preamble code.

Step 102: The terminal sends a random access preamble on the target RO.

Specifically, after determining the target RO for sending the random access Preamble code, the terminal sends the random access Preamble code on the target RO.

The base station receiving terminal sends the random access Preamble code on the target RO.

After receiving the random access preamble code sent by the terminal on the target RO, the base station determines the type of the terminal according to the SSB2RO mapping period to which the target RO belongs or the number of the SSB2RO association period and the association relationship between the RO and the terminal type.

For example, the relationship between RO and terminal type is as follows:

The number of the SSB2RO association period to which the RO that the CE UE is allowed to use is 1; the number of the SSB2RO association period to which the RO that the RedCap UE is allowed to use is 2; the number of the SSB2RO association period to which the RO that the small data UE is allowed to use is 3.

Then the base station determines that the type of the terminal is CE UE after receiving the random access Preamble code sent by the terminal on the RO included in the SSB2RO association period numbered 1; After the random access Preamble code sent on the RO, determine that the type of the terminal is RedCap UE; after receiving the random access Preamble code sent by the terminal on the RO included in the SSB2RO association period numbered 3, the base station determines that the terminal The type is small data UE.

In the information transmission method provided by the embodiments of the present disclosure, different ROs are used to distinguish different types of terminals, and different types of terminals send random access preambles in different ROs, and the network side transmits random access preambles according to the The RO determines the type of the terminal, which avoids resource fragmentation and improves resource utilization.

Optionally, before the determining of the target RO for sending the random access preamble, the method further includes:

Specifically, in the embodiment of the present disclosure, the association relationship between the RO and the terminal type may be configured by the network side.

The base station sends a RACH configuration message to the terminal, where the RACH configuration message includes the association relationship between the RO and the terminal type.

The terminal receives the RACH configuration message sent by the base station, and parses the association relationship between the RO and the terminal type from the RACH configuration message.

The RACH configuration message may be at the cell level or at the network level.

The base station may send the RACH configuration message to the terminal through a physical broadcast channel (Physical Broadcast Channel, PBCH).

The RACH configuration message may be carried through a master system information block (Master Information Block, MIB).

The RACH configuration message may also be carried through a system information block (System Information Block, SIB). For example, the RACH configuration message is carried by the first type of system information block SIB1, or the RACH configuration message is carried by the second type of system information block SIB2, and so on.

In the information transmission method provided by the embodiments of the present disclosure, the network side configuration method informs the terminal of the association relationship between the RO and the terminal type, which makes the association between the RO and the terminal type more flexible and expands the scope of application of the method.

Optionally, the RACH configuration message is the first type of system information block SIB1.

Specifically, in the embodiment of the present disclosure, terminal type identification configuration information is added to SIB1, and the RACH configuration message is carried through SIB1.

For example, the base station adds configuration information in SIB1 to indicate that N1 SSB-to-RO mapping cycles in C association periods are used for random access of CE UEs; N2 SSB-to-RO mapping cycles are used for RedCap UEs random access; N3 SSB-to-RO mapping cycles are used for random access of small data, and so on. Different types of terminals send the Preamble code on the RO included in the corresponding SSB-to-RO mapping cycle. The base station determines the type of the terminal by detecting the RO set that receives the preamble code.

In the information transmission method provided by the embodiment of the present disclosure, the RACH configuration message is carried by the SIB1, which can be better compatible with existing protocols and has better forward compatibility.

Optionally, the association relationship is pre-configured by a protocol.

Specifically, in the embodiment of the present disclosure, the association relationship between the RO and the terminal type is preconfigured through a protocol.

For example, pre-configured through the protocol: the synchronization signal block to the random access channel (synchronization signal block to RACH occasion, SSB2RO/SSB-to-RO) mapping cycle (mapping cycle) of the RO to which the type 1 terminal is allowed to use The number is 1, the number of the SSB2RO mapping cycle to which the RO that the type 2 terminal is allowed to use is 2, ..., the number of the SSB2RO mapping cycle to which the RO that the type n terminal is allowed to use is n.

In the information transmission method provided by the embodiments of the present disclosure, the association relationship between the RO and the terminal type is preconfigured through the protocol, which reduces the signaling resource overhead and improves the information transmission efficiency.

Specifically, in the embodiment of the present disclosure, before the terminal determines the target RO for sending the random access Preamble code, the method further includes: the base station sends the first identification information to the terminal.

The first identification information is used to instruct the terminal to distinguish the types of different terminals through the SSB2RO mapping period or the SSB2RO association period.

The terminal receives the first identification information sent by the base station.

For example, the base station sends the first identification information through a 1-bit reserved bit in the MIB.

For another example, the base station sends the first identification information through a 1-bit reserved bit other than the MIB carried in the PBCH.

In the information transmission method provided by the embodiment of the present disclosure, the base station sends the first identification information to instruct the terminal to distinguish the types of different terminals through the SSB2RO mapping period or the SSB2RO association period, so that the base station can distinguish the types of different terminals through the SSB2RO mapping period or the SSB2RO association period. Type is controlled to improve reliability.

Optionally, the first identification information is carried by a 1-bit reserved bit in the main system information block MIB.

Specifically, in the embodiment of the present disclosure, the first identification information is carried through a 1-bit reserved bit in the MIB, that is, the first identification information is sent through a 1-bit reserved bit in the MIB.

For example, the value of the 1-bit reserved bit in the MIB indicates that the terminal is not allowed to distinguish different terminal types through the SSB2RO mapping period or the SSB2RO association period; the value of the 1-bit reserved bit in the MIB indicates that the terminal is allowed to pass the SSB2RO mapping period or The SSB2RO association period distinguishes the types of different terminals.

The second identification information is used to instruct the terminal to distinguish the types of different terminals through the SSB2RO mapping period or the SSB2RO association period.

The value of the 2-bit reserved bits in the PBCH is 10, indicating that the type set of terminals that are allowed to be distinguished by the terminal through the SSB2RO mapping period or the SSB2RO association period is the second set.

The value of the 2-bit reserved bits in the PBCH is 11, indicating that the type set of terminals that are allowed to be distinguished by the terminal through the SSB2RO mapping period or the SSB2RO association period is the third set.

The terminal types included in the first set, the second set and the third set can be configured according to specific conditions. The configuration mode can be configured by the base station or pre-configured by the protocol.

For example, the value of the 2-bit reserved bits in the PBCH indicates that the terminal is not allowed to distinguish the types of different terminals through the SSB2RO mapping period or the SSB2RO association period.

The value of the 2-bit reserved bits in the PBCH is 01 to indicate that the terminal is allowed to distinguish three types of UEs: CE UEs, RedCap UEs and small data UEs through the SSB2RO mapping period or the SSB2RO association period.

Optionally, the target RO is the RO included in the N target SSB2RO mapping periods within the C target SSB2RO association periods; C and N are both positive integers.

Specifically, in the embodiment of the present disclosure, the RO used by the terminal to send the random access Preamble code is the RO included in the N SSB2RO mapping periods within the C SSB2RO association periods; C and N are both positive integers.

That is, the RO used by a type of terminal to send the random access Preamble code may be the RO in the same SSB2RO association period, or may be the RO in different SSB2RO association periods.

The RO used by a type of terminal to send the random access Preamble code may be the RO in the same SSB2RO mapping period, or may be the RO in different SSB2RO mapping periods.

For example, the terminal with type number 1 uses the RO in the SSB2RO association period numbered 1 to send the random access Preamble code, and the terminal with type number 2 uses the RO in the SSB2RO association period numbered 2 to send the random access Preamble code, The terminal whose type number is 3 uses the RO in the SSB2RO association period number 3 to send the random access Preamble code.

For another example, the terminal with type number 1 uses the RO in the mapping period of SSB2RO with number 1 in the SSB2RO association period with number 1 to send the random access Preamble code, and the terminal with type number 2 uses SSB2RO with number 1 to associate. The RO in the mapping period of the SSB2RO numbered 2 in the period sends a random access Preamble code, and the terminal with type number 3 uses the RO in the mapping period of the SSB2RO numbered 3 in the SSB2RO association period numbered 1 to send random access Access the Preamble code.

It should be noted that the above examples are not exhaustive, as long as it can ensure that the mapping periods of the SSB2ROs to which the ROs used by different terminals do not overlap, and the number of the mapping periods of the SSB2ROs to which the ROs belong can be used to distinguish different terminals. Other configuration methods are feasible. , and will not be repeated here.

Optionally, the association relationship is: the type number of the terminal corresponds to the number of the SSB2RO mapping period or the SSB2RO association period to which the RO that the terminal is allowed to use belongs, and the number of the SSB2RO mapping period or the SSB2RO association period corresponding to different type numbers. different.

Specifically, in the embodiment of the present disclosure, the association relationship between the RO and the terminal type is as follows:

The type number of the terminal corresponds to the number of the SSB2RO mapping period or the SSB2RO association period to which the RO that the terminal is allowed to use belongs, and the numbers of the SSB2RO mapping period or the SSB2RO association period corresponding to different type numbers are different.

For example, the relationship between RO and terminal type is as follows:

In the information transmission method provided by the embodiment of the present disclosure, the type number of the terminal corresponds to the number of the SSB2RO mapping period or the SSB2RO association period to which the RO that the terminal is allowed to use belongs, and the number of the SSB2RO mapping period or the SSB2RO association period corresponding to different type numbers Therefore, different types of terminals are distinguished, the fragmentation of resources is avoided, and the utilization rate of resources is improved.

Optionally, the association relationship is expressed by a formula as follows:

m=mod(n _cycle ,M)+n

Specifically, in the embodiment of the present disclosure, the relationship between the RO and the terminal type is expressed by the formula as follows:

m=mod(n _cycle ,M)+n

For example, starting from the frame (SFN#0) with the System Frame Number (SFN) of 0, the SSB-to-RO mapping cycle with mod(n _cycle , M)=0 or the RO included in the association period is used for The terminal of the first type (terminal with type number 1) is used, and the SSB-to-RO mapping cycle with mod(n _cycle , M)=1 or the RO included in the association period is used for the terminal of the second type (type number is 1). 2), the SSB-to-RO mapping cycle with mod(n _cycle , M)=2 or the RO included in the association period is used for the third type of terminal (the type number is 3), and this analogy.

The information transmission method provided by the embodiment of the present disclosure establishes a corresponding relationship between the type number of the terminal and the modulo value of the SSB2RO mapping period or the number of the SSB2RO association period to which the RO that the terminal is allowed to use belongs, thereby distinguishing different types of terminals, avoiding the need for The fragmentation of resources improves the utilization of resources.

The method in the above-mentioned embodiment is described in one step with several specific examples below:

example 1:

The 5G system introduces various types of terminals in Rel-17 and subsequent versions. These terminals are suitable for different application scenarios and have corresponding capabilities and supporting technologies. They need to be distinguished as soon as possible to achieve optimal performance. It is assumed that there are three new types of terminals in the current system that need to be distinguished in the random access procedure, namely: CE UE, RedCap UE and small data UE. The network side configures the same RACH configuration for these three different types of terminals, and determines the type of the terminal by using some ROs in the ROs determined by the RACH configuration.

It is assumed that the network side distinguishes specific types of terminals on RO resources by configuring specific ROs for different types of terminals.

Assuming that the current system is FDD, the frequency band is FR1, and the RACH resource number configured by the base station for three different types of terminals is RACH configuration#27 (for the specific parameter configuration and meaning, please refer to the reference document TS38.211, Table 6.3.3.2-2). It is assumed that the number of synchronization signal block candidates (SSB candidates) in the current system is 8. Then according to the parameter ssb-perRACH-OccasionAndCB-PreamblesPerSSB carried in SIB1, the mapping relationship between SSB, RO and preamble code can be known. It is assumed that each RO is mapped to one SSB, and each SSB is mapped to 8 preamble codes. Based on this configuration, the size of the SSB-to-RO association period is 10 slots at this time. Suppose SCS=15kHz, so the SSB-to-RO association period is 10ms.

Based on the above configuration, a schematic diagram of ROs that can be used for RACH transmission and cannot be used for RACH transmission within an association period is shown in FIG. 2 .

The base station additionally sends configuration information of ROs corresponding to different types of terminals in SIB1, including:

1) The number of SSB-to-RO association period or SSB-to-RO mapping cycle included in the time window for terminal type identification.

2) Indicate N1 SSB-to-RO mapping cycles in C association periods for random access of type 1 terminals; N2 SSB-to-RO mapping cycles for random access of type 2 terminals; N3 SSBs -to-RO mapping cycle is used for random access of type 3 terminals, and so on. Different types of terminals send the Preamble code on the corresponding RO.

Among them, N1 cycles, N2 cycles, and N3 cycles do not overlap with each other. N1+N2+N3+...<=sum of cycles included in C association periods. C, N1, N2, N3... are integers greater than or equal to 1.

Assuming C=3, N1=1, N2=1, N3=1, that is, CE UE corresponds to the first SSB-to-RO mapping cycle, RedCap UE corresponds to the second SSB-to-RO mapping cycle, and small data UE corresponds to The third SSB-to-RO mapping cycle. According to this information, it is determined that all ROs included in the first SSB-to-RO mapping cycle in Figure 2 are used for CE UEs, and all ROs included in the second SSB-to-RO mapping cycle are used for RedCap UEs. All ROs included in the three SSB-to-RO mapping cycles are used for small data UEs. That is, the CE UE can only send the corresponding preamble code in any RO contained in the first SSB-to-RO mapping cycle, and the RedCap UE can only send the corresponding preamble code in any RO contained in the second SSB-to-RO mapping cycle. Send the corresponding preamble code, the small data UE can only send the corresponding preamble code in any RO included in the third SSB-to-RO mapping cycle.

Correspondingly, if the network side detects and receives a preamble code in any RO included in the first SSB-to-RO mapping cycle, it determines that the terminal is a CE UE; if it is in the second SSB-to-RO mapping cycle If the preamble code is detected in any RO included, it is determined that the terminal is a RedCap UE; if the preamble code is detected and received in any RO included in the third SSB-to-RO mapping cycle, it is determined that the terminal is a RedCap UE .

Example 2:

When configuring the corresponding RO numbers {N1, N2, N3...} for different types of terminals, the base station may configure different types of terminals by means of a bitmap. That is, different types of terminals determine which ROs within the C association periods are used for their own preamble transmission according to their respective bitmaps.

Each type of terminal determines its corresponding RO according to a bitmap with a length of 3 bits. 1 in the bitmap indicates that the RO is available, and 0 indicates that the RO is unavailable.

Assuming that the bitmaps corresponding to CE UE, RedCap UE and small data UE are {100}, {010} and {001} respectively, then the SSB-to-RO mapping cycle corresponding to the three types of terminals is: CE UE corresponds to the first SSB-to-RO mapping cycle, RedCap UE corresponds to the second SSB-to-RO mapping cycle, small data UE corresponds to the third SSB-to-RO mapping cycle.

For the methods for the terminal to send the preamble code and the base station to detect and receive the preamble code, reference may be made to Example 1, which will not be repeated here.

Example 3:

One RO can correspond to multiple SSBs, that is, one SSB-to-RO association period can contain multiple SSB-to-RO mapping cycles.

The configuration information of the ROs corresponding to different types of terminals may be pre-configured through a protocol, or refer to Example 1 or Example 2, which will not be repeated here.

Example 4:

In this example, a 1-bit reserved bit in the MIB is used to determine whether part of the SSB-to-RO mapping cycle or association period configured in the current C association periods (association periods) is used for identification of different types of UEs.

The value of this 1-bit reserved bit is 0, indicating that the identification of different types of UEs through the SSB-to-RO mapping cycle or association period is not supported.

The value of the 1-bit reserved bit is 1 to support the identification of different types of UEs through the SSB-to-RO mapping cycle or association period.

Which SSB-to-RO mapping cycle or association period is used for identification of different types of terminals can be determined in a pre-defined manner in the protocol.

For example, according to the protocol definition, starting from SFN #0, the SSB-to-RO mapping cycle with mod(n _cycle ,M)=0 or the RO included in the association period is used for the first type of terminal, mod(n _cycle ,M) The RO included in the SSB-to-RO mapping cycle or the association period of =1 is used for the second type of terminal, and the RO included in the SSB-to-RO mapping cycle or association period with mod(n _cycle ,M)=2 is used for the second type of terminal. Three types of terminals, and so on.

Among them, n _cycle is the number of SSB-to-RO mapping cycle or SSB-to-RO association period. M is the number of SSB-to-RO mapping cycles or SSB-to-RO association periods included in the predefined SSB-to-RO mapping cycle or SSB-to-RO association period window for terminal type identification, different types The terminals correspond to different SSB-to-RO mapping cycles or SSB-to-RO association periods, and M can also be understood as the number of types of terminals that need to be distinguished.

A terminal of a certain type can only send the preamble code on the RO corresponding to the terminal of this type. Once the network side detects and receives the preamble code, it determines the specific type of the terminal sending the preamble code according to the terminal type corresponding to the RO, and performs corresponding operations according to the terminal type.

Example 5:

In this example, the 2-bit reserved bits in the PBCH are used to determine whether the SSB-to-RO mapping cycle or association period configured in the current C association periods (association periods) is partially used for identification of different types of UEs. The preamble code is sent on the corresponding RO.

The value of the 2-bit reserved bits in the PBCH is 00, indicating that the terminal is not allowed to distinguish the types of different terminals through the SSB2RO mapping period or the SSB2RO association period;

The value of the 2-bit reserved bits in the PBCH is 10 to indicate that the type set of terminals that the terminal is allowed to distinguish through the SSB2RO mapping period or the SSB2RO association period is the second set;
