In order to facilitate understanding of the technical solutions of the embodiments of the present application, technical concepts related to the embodiments of the present application will be described below.

The random access is an important process for establishing wireless connection between the UE and the network side, and uplink synchronization can be obtained between the UE and the base station through the random access to apply for uplink resources. The random access procedure is divided into a contention-based random access procedure and a non-contention-based random access procedure. Wherein, the contention based random access procedure includes a four-step random access procedure and a two-step random access procedure, and fig. 2 shows a flow chart of the four-step random access procedure, as shown in fig. 2, the four-step random access procedure includes the following steps:

step 201: the UE sends Msg1 to the base station.

Here, the sending of the Msg1 by the UE to the base station may specifically be implemented by the following procedures:

-the UE determines the relation of Synchronization Signal Block (SSB) to PRACH resources (configured by higher layers);

-the UE receiving a set of SSBs and determining its Reference Signal Received Power (RSRP) value, selecting an appropriate SSB according to a threshold;

-the UE determining Physical Random Access Channel (PRACH) resources based on the selected SSBs and their correspondence to RACH resources;

-UE transmitting preamble on PRACH time frequency domain resources.

Step 202: and the UE receives the Msg2 sent by the base station.

Here, the UE receiving the Msg2 sent by the base station may specifically be implemented by the following procedures:

-the UE starts an RAR Window (RA-Response Window) at a first Physical Downlink Control Channel (PDCCH) occasion (occasion) after the preamble is transmitted and monitors the PDCCH during the Window operation, wherein the PDCCH is a PDCCH scrambled with an RA-RNTI. RA-RNTI is related to PRACH time frequency resources selected by UE, and the calculation of RA-RNTI is as follows:

RA-RNTI＝1+s_id+14×t_id+14×80×f_id+14×80×8×ul_carrier_id

wherein, s _ id is the index of the first OFDM symbol of PRACH resource (s _ id is more than or equal to 0 and less than 14);

t _ id is the index of the first time slot of the PRACH resource in the system frame (t _ id is more than or equal to 0 and less than 80);

f _ id is the index of the PRACH occasion in the frequency domain (f _ id is more than or equal to 0 and less than 8);

UL _ carrier _ id is an Uplink (UL) carrier used for preamble index transmission.

After the UE successfully monitors the PDCCH scrambled by the RA-RNTI, the PDSCH scheduled by the PDCCH can be obtained, wherein the PDSCH comprises RAR.

Step 203: the UE sends Msg3 to the base station.

Msg3 is mainly used to send UE ID to the network to resolve contention conflicts. For example, if the access procedure is an initial access random procedure, the Msg3 carries an RRC layer message, that is, a CCCH SDU, which includes a UE ID and a connection establishment request (RRCSetupRequest); if the RRC reestablishment is carried, a reestablishment request (RRCRESTABLISHRNITENTRequest) is carried.

Step 204: and the UE receives the Msg4 sent by the base station.

Msg4 has two roles, one is for contention conflict resolution; the second is the transmission of RRC configuration messages to the terminal. Here, if the UE receives the DCI format 1 _0scrambled by the Cell-Radio Network Temporary Identifier (C-RNTI) and the PDSCH corresponding thereto, the random access is completed; and if the terminal receives the DCI format 1 _0scrambled by the TC-RNTI and the PDSCH corresponding to the DCI format 1 _0scrambled by the TC-RNTI and the content is compared successfully, the random access is finished.

The two-step random access procedure is standardizing the discussion procedure and is in the research phase. The two-step random access process can improve time delay and simultaneously reduce signaling overhead, and at present, a basic mode is that MsgA transmits Msg1 and Msg3 of the four-step random access process, and MsgB transmits Msg2 and Msg4 of the four-step random access process.

Fig. 3 shows a flow chart of a two-step random access procedure, which, as shown in fig. 3, comprises the following steps:

step 301: the UE sends MsgA to the base station.

MsgA transmits Msg1 and Msg3 of a four-step random access procedure, i.e. MsgA includes a preamble and an Uplink data Channel, where the Uplink data Channel is, for example, a Physical Uplink Shared Channel (PUSCH).

Step 302: and the UE receives the MsgB sent by the base station.

MsgB transports Msg2 and Msg4 of a four-step random access procedure.

In the two-step random access process, the PUSCH in the MsgA needs to transmit content similar to Msg3 in the four-step random access process, such as UE ID and other information for resolving contention conflict. The setting of the transmission parameters in the two-step random access procedure is blank.

On one hand, in the two-step random access process, the PUSCH of the MsgA needs to support different Payload (Payload) sizes to support multiple Radio Resource Control (RRC) connection states. In the four-step random access process, the Payload and the resource size of the PUSCH of the Msg3 are configured by the network device to the user equipment. In the two-step random access process, the network device cannot predict Payload and resources, so blind detection of Payload and resources is required, and a corresponding mechanism is also required.

On the other hand, in the two-step random access process, the leading part of the MsgA is a sequence with a low peak-to-average ratio, and has a high acquisition probability. The PUSCH of MsgA needs to have the same or similar acquisition probability to ensure the success of two-step random access. However, when MsgA transmits information other than collision resolution, such as normal user data, it should require a lower base station acquisition probability than preamble. Therefore, the higher spectrum efficiency of the common user data can be ensured, and the wireless resources can not be used excessively. Furthermore, the PUSCH portion may require the transmission of new added control information. The probability of acquisition of control information also needs to be different from the data. However, the PUSCH portion of Msg3 in the current four-step random access procedure cannot achieve such an effect. Therefore, the following technical scheme of the embodiment of the application is provided.

Fig. 4 is a schematic flowchart of a transmission parameter determining method provided in an embodiment of the present application, and as shown in fig. 4, the transmission parameter determining method includes the following steps:

step 401: the user equipment sends a first uplink data channel in a first message according to first information, wherein the first message comprises the first uplink data channel and a first lead code; wherein the first information is used for determining at least one of the following transmission parameters of the first uplink data channel: time domain resources, frequency domain resources, and coding modes.

The user equipment in the embodiment of the application can be any equipment capable of communicating with a network, such as a mobile phone, a notebook, a tablet computer, a vehicle-mounted terminal, a wearable terminal and the like.

The network device in the embodiment of the application includes but is not limited to an LTE base station (eNB), an NR base station (gNB.)

In an embodiment, the technical solution of the embodiment of the present application is applied to a two-step random access process, where the two-step random access process includes two steps: 1) The user equipment sends MsgA to the network equipment; 2) And the network equipment sends the MsgB to the user equipment.

In an embodiment, the first message is MsgA in a two-step random access procedure, and the first message includes a first uplink data channel and a first preamble. Here, the first uplink data channel is, for example, a PUSCH. In this embodiment of the present application, a user equipment sends a first uplink data channel in a first message according to first information, where the first information is used to determine at least one of the following transmission parameters of the first uplink data channel: time domain resources, frequency domain resources, and coding modes.

In the embodiment of the application, the first information is agreed; or the first information is configured to the user equipment by the network equipment. For example: and the base station and the user equipment appoint at least one transmission parameter of time domain resources, frequency domain resources and a coding mode of the PUSCH of the MsgA in the two-step random access process, and the user equipment sends the PUSCH of the MsgA according to the transmission parameters. For example: and the base station configures at least one transmission parameter of time domain resources, frequency domain resources and a coding mode of the PUSCH of the MsgA in the two-step random access process for the user equipment, and the user equipment sends the PUSCH of the MsgA according to the transmission parameters.

How to determine each transmission parameter of the first uplink data channel is described below, it should be noted that the symbol in this embodiment may be a symbol Orthogonal Frequency Division Multiplexing (OFDM) symbol, and a payload (payload) can be transmitted on the first uplink data channel in this embodiment.

1) Time domain resources

And the time domain resource of the first uplink data channel is determined based on the initial symbol position of the first uplink data channel and the number of symbols occupied by the first uplink data channel.

1.1 A start symbol position of the first uplink data channel is determined based on the first preamble.

In an embodiment, a first offset is provided between a start symbol of the first uplink data channel and an end symbol of the first preamble, and the first offset is one or more symbols. Further, a start symbol of the first uplink data channel is located after an end symbol of the first preamble.

For example: the ending symbol of the first preamble is symbol (i), the starting symbol of the first uplink data channel is symbol (i + N), N represents a first offset, and N is a positive integer.

1.2 The number of symbols occupied by the first uplink data channel is determined based on the load transmitted by the first uplink data channel.

Here, the number of symbols occupied by the first uplink data channel is proportional to the load transmitted by the first uplink data channel.

In an embodiment, a proportional relationship between the number of bits of the payload transmitted by the first uplink data channel and the number of bits of the reference payload is a first proportional relationship, a proportional relationship between the number of symbols occupied by the payload transmitted by the first uplink data channel and the number of symbols occupied by the reference payload is a second proportional relationship, and the first proportional relationship and the second proportional relationship are the same.

For example: the number of symbols occupied by the payload transmitted by the first uplink data channel = ceiling (number of bits of the payload transmitted by the first uplink data channel/number of bits of the reference payload ×) number of symbols occupied by the reference payload. Here, ceiling represents rounding up.

For example: the number of symbols occupied by the load transmitted by the first uplink data channel = floor (number of bits of the load transmitted by the first uplink data channel/number of bits of the reference load × number of symbols occupied by the reference load). Here, floor stands for rounding down.

2) Frequency domain resources

The frequency domain Resource of the first uplink data channel is determined based on a starting Resource Block (RB) position of the first uplink data channel and the number of symbols occupied by the first uplink data channel.

2.1 A starting RB location of the first uplink data channel is determined based on the first preamble.

In an embodiment, a second offset is provided between the starting RB of the first uplink data channel and the starting RB of the first preamble, and the second offset is one or more RBs.

Further, a start RB of the first uplink data channel is located after the start RB of the first preamble; or, the starting RB of the first uplink data channel is located before the starting RB of the first preamble.

For example: the starting RB of the first preamble is RB (j), the starting RB of the first uplink data channel is RB (j + M), M represents a second offset, and M is a positive integer or a negative integer.

2.2 The number of RBs occupied by the first uplink data channel is determined based on the load transmitted by the first uplink data channel.

Here, the number of RBs occupied by the first uplink data channel is proportional to the load transmitted by the first uplink data channel.

In an embodiment, a proportional relationship between the number of bits of the load transmitted by the first uplink data channel and the number of bits of the reference load is a first proportional relationship, a proportional relationship between the number of RBs occupied by the load transmitted by the first uplink data channel and the number of RBs occupied by the reference load is a third proportional relationship, and the first proportional relationship and the third proportional relationship are the same.

For example: the number of RBs occupied by the load transmitted by the first uplink data channel = ceiling (number of bits of the load transmitted by the first uplink data channel/number of bits of the reference load × number of RBs occupied by the reference load). Here, ceiling represents rounding up.

For example: the number of RBs occupied by the load transmitted by the first uplink data channel = floor (number of bits of the load transmitted by the first uplink data channel/number of bits of the reference load × number of RBs occupied by the reference load). Here, floor stands for rounding down.

3) Time domain resources and frequency domain resources

3.1 Time domain resources of the first uplink data channel are determined based on a starting symbol position of the first uplink data channel and the number of symbols occupied by the first uplink data channel.

Here, the time domain resource of the first uplink data channel may refer to the description in 1) above, and is not described herein again.

3.2 Frequency domain resources of the first uplink data channel are determined based on a starting Resource Block (RB) position of the first uplink data channel and the number of symbols occupied by the first uplink data channel.

Here, the frequency domain resource of the first uplink data channel may refer to the description in 2) above, and is not described herein again.

3.3 The number of Resource Elements (REs) occupied by the first uplink data channel is determined based on the load transmitted by the first uplink data channel.

Here, the number of REs occupied by the first uplink data channel is proportional to the load transmitted by the first uplink data channel.

In an embodiment, a proportional relationship between the number of bits of the payload transmitted by the first uplink data channel and the number of bits of the reference payload is a first proportional relationship, a proportional relationship between the number of REs occupied by the payload transmitted by the first uplink data channel and the number of REs occupied by the reference payload is a fourth proportional relationship, and the first proportional relationship and the fourth proportional relationship are the same.

For example: the number of REs occupied by the payload transmitted by the first uplink data channel = ceiling (the number of bits of the payload transmitted by the first uplink data channel/the number of bits of the reference payload ×) the number of REs occupied by the reference payload). Here, ceiling represents rounding up.

For example: the number of REs occupied by the payload transmitted by the first uplink data channel = floor (number of bits of the payload transmitted by the first uplink data channel/number of bits of the reference payload ×) the number of REs occupied by the reference payload. Here, floor stands for rounding down.

Based on this, the user equipment determines the number of RBs occupied by the first uplink data channel in the frequency domain and the number of symbols occupied by the first uplink data channel in the time domain according to the number of REs occupied by the first uplink data channel.

4) Coding method

And the coding mode of the first uplink data channel is determined according to the load type transmitted by the first uplink data channel.

In an embodiment, the payload transmitted by the first uplink data channel includes a first type payload and a second type payload, and the first type payload and the second type payload adopt independent coding methods. Further, the resources of the second type of payload are appended to the resources of the first type of payload.

In an embodiment, the ue determines the resource of the second type of load according to the number of bits and the resource of the first type of load, the number of bits of the second type of load, and a rate ratio of the first type of load to the second type of load. In another embodiment, the ue determines the resources of the second type of load according to the resources of the first type of load and the resource configuration ratio of the first type of load to the second type of load.

In the above scheme, the resources include time domain resources and/or frequency domain resources.

According to the scheme, the two-step random access process can support more payload sizes, so that the flexibility of access data transmission is improved while the performance and the access time delay are ensured.

The scheme also introduces dual payload, and ensures that different types of information are protected at different levels. The introduction of different encodings may also achieve different processing time requirements for control or general data.

The technical solution of the embodiment of the present application is described below with reference to a specific application example, where MsgA in the application example is the first message, and PUSCH is the first uplink data channel.

Application example 1

The user equipment sends MsgA using the transmit architecture as shown in fig. 5. Each preamble and one PUSCH define an offset in the time domain. In the example shown in fig. 5, the offset between the preamble and the PUSCH in the time domain is 1, that is, the first OFDM symbol after the preamble is the starting position of the PUSCH. The offset may be any integer from 1 to N in units of OFDM symbols. The obtaining mode of the offset can be determined by preamble parameters or modes such as broadcast issuing of network equipment and the like.

And the user equipment determines the number of the occupied OFDM symbols when the PUSCH is transmitted according to the bit number of the actually transmitted payload and the bit number of the reference payload. The proportional relationship between the number of actually transmitted payload bits and the number of reference payload bits is the same as the proportional relationship between the number of OFDM symbols occupied by actually transmitted payload and the number of OFDM symbols occupied by reference payload.

In one example, the number of OFDM symbols occupied by the actually transmitted payload is determined using the following formula:

the number of OFDM symbols occupied by the actually transmitted payload = ceiling (the number of bits of the actually transmitted payload/the number of bits of the reference payload ×. The number of OFDM symbols occupied by the reference payload). Here, ceiling represents rounding up.

In another example, the number of OFDM symbols occupied by the actually transmitted payload is determined using the following formula:

the number of OFDM symbols occupied by the actual transmitted payload = floor (number of bits of actual transmitted payload/number of bits of reference payload ×. Number of OFDM symbols occupied by reference payload). Here, floor stands for rounding down.

In one example, 54 bits are used as the number of bits of the reference payload, and 14 symbols are used as the number of OFDM symbols occupied by the reference payload.

In one example, the PUSCH occupies a fixed number of RBs, such as 6 RBs.

Taking fig. 5 as an example, the PUSCH of X OFDM symbols in fig. 5 is sent with reference payload size = a bits. When the user equipment transmits the payload with b bits, the number of transmitted symbols is Y = ceiling (b/a) or Y = floor (b/a) where ceiling represents rounding-up and floor represents rounding-down.

Application example two

The user equipment transmits MsgA using a transmit architecture as shown in fig. 6. Each preamble and one PUSCH define an offset in the frequency domain. In the example shown in fig. 6, the offset of the preamble and the PUSCH in the frequency domain is Delta RB, i.e. the difference between the first RB of the preamble and the RB where the PUSCH starts. The offset may be any positive or negative integer. The obtaining mode of the offset can be determined by preamble parameters or broadcast issuing of network equipment and the like.

And the user equipment determines the number of RBs occupied when the PUSCH is transmitted according to the bit number of the actually transmitted payload and the bit number of the reference payload. The proportional relation between the actually transmitted payload bit number and the reference payload bit number is the same as the proportional relation between the actually transmitted payload occupying RB number and the reference payload occupying RB number.

In one example, the number of RBs actually occupied by the payload is determined using the following equation:

number of RBs occupied by the actually transmitted payload = ceiling (number of bits of actually transmitted payload/number of bits of reference payload ×. Number of RBs occupied by reference payload). Here, ceiling represents rounding up.

In another example, the following formula is used to determine the number of RBs occupied by the actually transmitted payload:

number of RBs occupied by the actual transmitted payload = floor (number of bits of actual transmitted payload/number of bits of reference payload ×. Number of RBs occupied by reference payload). Here, floor stands for rounding down.

In one example, 54 bits are used as the number of bits of the reference payload, and 6 RBs are used as the number of RBs occupied by the reference payload.

In one example, the PUSCH occupies a fixed number of OFDM symbols, such as 14 symbols.

Application example three

Each preamble and one PUSCH of a user equipment define an offset in the time and frequency domain. The offset in the frequency domain is Delta RB, i.e., the difference between the first RB of the preamble and the RB where the PUSCH starts, and the offset in the frequency domain may be any positive or negative integer. The time domain offset is in units of OFDM symbols. The obtaining mode of the offset can be determined by preamble parameters or broadcast issuing of network equipment and the like.

And the user equipment determines the number of REs occupied when the PUSCH is transmitted according to the bit number of the actually transmitted payload and the bit number of the reference payload. The proportional relation between the actually transmitted payload bit number and the reference payload bit number is the same as the proportional relation between the actually transmitted payload occupied RE number and the reference payload occupied RE number.

And the user equipment determines the number of RBs occupied by the PUSCH on the frequency domain and the number of OFDM symbols occupied by the PUSCH on the time domain according to the number of REs occupied by actually transmitted payload.

Application example four

In the two-step random access process, the PUSCH may transmit two types of payloads. Two types of payload are used to transmit different types of information. Wherein the first payload (i.e., the first type of load) transmits necessary information of the random access procedure, such as UE ID for user collision resolution, RNTI, control channel, HARQ, etc. The second payload (i.e., the second type of payload) carries other information.

The first and second payloads are independently encoded, and in one example, the encoding relationship of the first and second payloads is as shown in fig. 7. Wherein, two payloads may independently adopt a channel coding manner, for example: the first payload is encoded using polarization (polar) and the second payload is encoded using Low-density Parity-check (LDPC) codes. For another example: the first payload and the second payload both employ LDPC encoding.

Furthermore, the time frequency resource of the second payload is mapped after being attached to the time frequency resource of the first payload. For example: in terms of time domain, the OFDM symbol where the time-frequency resource of the second payload is located is behind the OFDM symbol of the time-frequency resource of the first payload. For another example: from the time-frequency sequence number, the RE sequence number where the time-frequency resource of the second payload is located is after the RE sequence number of the first payload.

The user equipment may determine the channel coding rate and the time-frequency resource used by the first payload and the second payload, respectively, through the broadcast parameters of the network equipment or by using a predetermined calculation method. In particular, the amount of the solvent to be used,

1) The user equipment obtains the rate ratio of the first payload and the second payload according to the broadcast parameters of the network equipment. The user equipment deduces the resource (RB number and/or OFDM symbol number) of the second payload according to the bit number and resource (RB number and/or OFDM symbol number) of the first payload, the rate obtained by the previous step and the bit number of the second payload.

2) The system appoints the code rate ratio and the implicit calculation mode of the first payload and the second payload. The user equipment deduces the resources (RB number and/or OFDM symbol number) of the second payload according to the bit number and resources (RB number and/or OFDM symbol number) of the first payload, the appointed code rate ratio and the bit number of the second payload.

3) The user equipment obtains the resource allocation ratio of the first payload and the second payload through the broadcast parameters of the network equipment, and determines the resource (RB number and/or OFDM symbol number) of the second payload according to the resource allocation ratio.

It should be noted that the technical solution in the embodiment of the present application may also be extended to other uplink channels that need to autonomously and flexibly transmit data bits. The coding method can realize data protection of different levels, and is a better solution for autonomously and flexibly selecting multi-level protection data transmission under payload based on the user equipment.
