Description

Random access method, electronic equipment and network equipment

This application claims the priority of a Chinese patent application filed with the State Intellectual Property Office, the application number is 201910755840.1, and the invention title is "a random access method, electronic equipment and network equipment" on August 15, 2019. The entire content of the application is approved The reference is incorporated in this application.

Technical field

The embodiments of the present application relate to the field of wireless communication technologies, and in particular, to a random access method, electronic equipment, and network equipment in a wireless communication system.

Background technique

With the development of wireless communication technology, and the diversification of wireless communication technology application scenarios. More and more data transmission scenarios have transmission requirements such as low delay. For example, ultra-reliable low-latency (URLLC), machine type communication (MTC), and Internet of Things (IoT) scenarios.

When an existing electronic device initiates random access, it usually uses a 4-step random access (4-step random access channel, 4-step RACH) method as shown in FIG. 1 to access the network device. As shown in Figure 1, first, the electronic device performs step 1 to send a physical random access channel (PRACH) preamble to the network device; then, the electronic device receives the response information from the network device to the PRACH preamble. (Step 2 shown in Figure 1) After that, it sends the uplink shared channel (Physical uplink shared channel, PUSCH) that carries uplink data to the network device (Step 3 shown in Figure 1); finally, the electronic device receives the network The device's contention resolution information for this PUSCH.

However, using the 4-step RACH method shown in Figure 1, the electronic device sends the PUSCH carrying uplink data to the network device only after successfully receiving the response information of the network device to the PRACH preamble (that is, the PUSCH that carries the uplink data in step 2) After the line is successful, step 3) is executed. Therefore, it will cause a delay for the electronic device to send the PUSCH to the network device. This affects the efficiency of random access.

In addition, using the 4-step RACH method as shown in FIG. 1, if the electronic device does not receive the response information of the network device to the PRACH preamble, the electronic device will give up sending the PUSCH carrying the uplink data to the network device. Then this random access request fails. Therefore, adopting the 4-step RACH method as shown in Figure 1 will also affect the success rate of random access.

detailed description

The embodiment of the present application provides a random access method. Specifically, a 2-step random access method is provided. As shown in FIG. 2, the electronic device sending the PRACH preamble to the network device and sending the PUSCH carrying uplink data are decoupled. Compared with the 4-step RACH method shown in FIG. 1, the electronic device sends a PUSCH carrying uplink data to the network device, regardless of whether the electronic device successfully receives the response information of the network device to the PRACH preamble. As shown in Figure 2, the electronic device directly executes step a to send the PRACH preamble for accessing the network device and the PUSCH carrying uplink data to the network device. Therefore, there will be no delay caused by step 1 and step 2 to step 3 in the 4-step RACH method shown in FIG. 1, which improves the efficiency of random access of electronic devices.

In addition, using the 2-step RACH method shown in Figure 2, even if the electronic device does not successfully receive the response of the network device to the PRACH preamble, the electronic device can still send the PUSCH carrying the uplink data to the network device, and the network device can only Respond to the random access request of the electronic device based on the PUSCH carrying the uplink data. Therefore, adopting the 2-step RACH method as shown in FIG. 2 can also improve the success rate of random access of electronic devices.

The random access method in the embodiments of the present application can be applied to the process of electronic equipment accessing the unlicensed spectrum (5th-Generation New Radio Unlicensed Spectrum, 5G NR-U) of the new wireless network of the fifth generation mobile communication system. Exemplarily, the unlicensed spectrum of 5G NR may be a wireless local area network (Wi-Fi spectrum (for example, 5GHz frequency band), or applied to other spectrums. In addition, the random access method in the embodiment of the present application may also be applied to the fifth generation Other mobile communication systems developed later are not limited in the embodiment of this application.

Among them, network equipment can work in the following two working modes when using 5G NR-U:

Mode 1: Authorized spectrum assisted access NR-U (License spectrum Aided Access NR-U, LAA NR-U).

Specifically, 5G NR-U is a carrier aggregation technology. The primary serving cell (Primary Serving Cell, Pcell) can use the licensed spectrum, and the secondary serving cell (Secondary Serving Cell, Scell) can use the unlicensed spectrum. The network equipment aggregates the licensed spectrum with the unlicensed spectrum, transmits control signaling and high QoS data through the licensed spectrum, and transmits data through the unlicensed spectrum, thereby greatly increasing the downlink rate. Based on the above-mentioned aggregation of licensed and unlicensed spectrum, LAA NR-U also introduced LAA. Among them, LAA is defined in the 3rd Generation Partnership Project (The 3rd Generation Partnership Project, 3GPP) version 13 (revision 13, R13) and has been enhanced in R14.

Mode 2: Stand-alone NR-U (stand-alone NR-U).

For this mode, 5G NR-U does not use licensed spectrum and can work independently with unlicensed spectrum.

It is understandable that in the NR-U mode, in order to improve the utilization of the unlicensed spectrum, multiple wireless communication technologies can use the unlicensed spectrum, that is, the unlicensed spectrum is shared by multiple wireless communication technologies. For example, wireless communication technologies such as 5G NR-U and Wi-Fi can all use this unlicensed spectrum. In this case, there will be multiple wireless communication technologies competing to use the unlicensed spectrum resources at the same time. In order to reduce the collision of different wireless communication technologies due to competition, the electronic device may first detect the unlicensed spectrum before random access, and when it is determined that there is an idle resource, use the idle resource to initiate a random access request.

In some embodiments, the electronic device may determine whether the first resource is available by listening before talk (LBT) on the first resource. Among them, LBT means that the electronic device performs interception on the unlicensed spectrum resource before using the unlicensed spectrum resource. Specifically, the electronic device can listen to the surrounding wireless environment at the microsecond level to perform channel interference assessment, and if it is confirmed that the resource is free, the resource is considered available. Through LBT, the same spectrum resource can be shared with other wireless technologies in time sharing.

It should be noted that the application solution is explained in the 5G NR-U scenario, but all the embodiments in the application solution are applicable to other wireless networks that can support two-step random access technology.

The network device may also be a router or other wireless access device that can be configured as a base station, such as a drone, an aircraft, etc., which is not limited in the embodiment of the present application.

In the process of entering the base station 310.

It should be noted that the random access method in the embodiment of the present application may be applicable to any event that triggers random access. For example, the initial random access initiated by the electronic device when it is turned on or in the idle state; or, when the electronic device is in the connected state, the reestablishment chain is initiated due to the disconnection, the handover initiated by the position movement, and the uplink recovery initiated due to out-of-synchronization For synchronization, etc., the embodiment of the present application does not limit the specific scenario of the random access method.

The random access methods in the embodiments of the present application can all be implemented in an electronic device having a hardware structure as shown in FIG. 4 or an electronic device having a similar structure.

The following takes the random access process between the terminal device and the base station shown in (a) of FIG. 3 as an example, and the terminal device 300 of the structure shown in FIG. 4 is taken as an example to introduce the random access method of the embodiment of the present application.

In the embodiment of the present application, the terminal device 300 may send the PRACH preamble to the base station 310 through the random access channel transmission opportunity (RACH Occasion, RO) resource, and send the bearer to the base station 310 through the uplink shared channel transmission opportunity (PUSCH Occasion, PO) resource PUSCH with uplink data. Wherein, the PRACH preamble can be a PRACH preamble randomly selected by the terminal device 300 from the PRACH preamble sequence set, or it can also be a PRACH preamble determined from the PRACH preamble sequence set according to any rule. Not limited. In the embodiment of the present application, the uplink data carried in the PUSCH may include the identification of the terminal device 300 (for example, the UE ID) and the reason for establishing a radio resource control (Radio Resource Control, RRC). Exemplarily, as shown above, the reason for establishing the RRC may be initial random access, and may be due to handover, uplink synchronization, or chain reestablishment.

In the embodiment of the present application, the PO resource and the RO resource may be pre-configured resources with a corresponding relationship.

Exemplarily, the corresponding relationship between the PO resource and the RO resource may refer to the corresponding relationship between the RO resource for transmitting the PRACH preamble and the PO resource for transmitting uplink data when the terminal device performs step a as shown in FIG. 2. Among them, a PUSCH resource unit (PUSCH resource unit, PRU) carrying uplink data can be determined according to the PRACH preamble. The PRU refers to a resource unit composed of a PO resource for transmitting uplink data and a demodulation reference signal (DMRS) port number and/or DMRS sequence number used for transmitting uplink data.

As shown in FIG. 10A, FIG. 10B and S1010 in FIG. 11, the terminal device 300 may first determine the configuration information of the first resource and the configuration information of the second resource.

Wherein, the configuration information of the first resource includes, but is not limited to, the configuration of the frequency domain position of the first resource and the configuration of the time domain position of the first resource. The configuration information of the second resource includes, but is not limited to, the configuration of the frequency domain position of the second resource and the configuration of the time domain position of the second resource.

The first resource and the second resource may be any one of RO resources and PO resources. When the first resource includes one or more RO resources, the second resource includes one or more PO resources. When the first resource includes one or more PO resources, the second resource includes one or more RO resources.

Based on the configuration information of the first resource and the configuration information of the second resource, the terminal device can obtain the time domain interval between the first resource and the second resource, and the correspondence between the first resource and the second resource.

The time domain interval between the first resource and the second resource refers to the time interval between the time domain position of the first resource and the time domain position of the second resource. The terminal device 300 may adopt different resource detection methods according to the relationship between the time domain interval t′ between the first resource and the second resource and the first time threshold T to detect whether the first resource and/or the second resource are available. The time domain interval t'between the first resource and the second resource may refer to the time domain interval between the end time of the time domain window of the first resource and the start time of the time domain window of the second resource. Exemplarily, as shown in (a) in FIG. 5, the first resource is an RO resource, and the second resource is a PO resource. The time domain window of the first resource is [t1 _RO , t2 _RO ], and the time domain window of the second resource is [t1 _PO , t2 _PO ]. The time domain interval t'between the first resource and the second resource is the time domain between the end time t2 _{RO of the} time domain window [t1 _RO , t2 _RO ] and the start time t1 _PO of the time domain window [t1 _PO , t2 _PO ] The interval, that is, t'=t1 _PO- t2 _RO .

In the embodiment of the present application, the relationship between the time domain interval t′ of the first resource and the second resource and the first time threshold T can be divided into the following two types:

(1) The time domain interval t'between the first resource and the second resource is greater than or equal to the first time threshold T. That is, t'≥T.

(2) The time domain interval t'between the first resource and the second resource is smaller than the first time threshold T, that is, t'<T.

The first time threshold T may be specified by a standard protocol, for example, a standard protocol formulated by the European Telecommunications Standards Institute (ETSI). The first time threshold T may also be configured by the network device or determined in other ways, which is not limited in the embodiment of the present application. Exemplarily, the first time threshold T may be equal to 16 us. It should be noted that in different communication systems, the first time threshold may be a different protocol preset value, which is not limited in the embodiment of the present application.

It can be understood that if the first resource is an RO resource and the second resource is a PO resource, and the time domain interval t'between the first resource and the second resource is less than the first time threshold T, when the LBT of the RO resource is successful, The terminal device may send the PRACH preamble on the first resource, and send uplink data on the second resource. Because the time domain interval between the RO resource and the PO resource is smaller than the first time threshold T, it can be considered that there is no time interval between the RO resource and the PO resource. After the terminal device occupies the RO resource, the terminal device can continuously occupy the PO resource.

In the embodiment of the present application, it can be considered that the smallest unit of LBT is a subband, where multiple RO resources or multiple PO resources may be configured on one subband. If the terminal device succeeds in LBT of a subband, it can be considered that all resources on the subband can be used by the terminal device. If the time domain interval between multiple consecutive uplink transmissions of the terminal device is less than the first time threshold T, then The terminal device only needs to perform LBT before the first uplink transmission. It should be noted that the terminal device uses RO resources or PO resources configured on the same subband by default for multiple consecutive uplink transmissions.

Assuming that the time domain position of the first resource is before the second resource, the embodiment of the present application can divide the correspondence between the first resource and the second resource into the following three types according to the configuration information of the first resource and the configuration information of the second resource :

Correspondence of type (1): one first resource corresponds to one second resource.

Exemplarily, as shown in (a) of FIG. 5, the first resource includes one RO resource, and the second resource includes one PO resource.

Or, as shown in (b) of FIG. 5, the first resource includes 1 PO resource, and the second resource includes 1 RO resource.

Correspondence of type (2): the first resource configured in one or more time domain locations corresponds to one second resource.

Exemplarily, as shown in FIG. 6(b), the first resource includes 4 RO resources, the second resource includes 1 PO resource, and the 4 RO resources overlap in time domain position.

Or, as shown in (b) of FIG. 8, the first resource includes 4 PO resources, the second resource includes 1 RO resource, and the 4 PO resources overlap in time domain position.

Or, as shown in (a) of FIG. 6, the first resource includes 4 RO resources, the second resource includes 1 PO resource, and the 4 RO resources are configured at 2 time domain locations.

Or, as shown in (c) in Figure 6 and (d) in Figure 6, the first resource includes 4 RO resources, the second resource includes 1 PO resource, and the 4 RO resources are arranged in 4 time domain locations .

Or, as shown in (a) of FIG. 8, the first resource includes 4 PO resources, the second resource includes 1 RO resource, and the 4 PO resources are configured at 2 time domain positions.

Or, as shown in Figure 8 (c) and Figure 8 (d), the first resource includes 4 PO resources, the second resource includes 1 RO resource, and the 4 PO resources are configured in 4 time domains. position.

Correspondence of type (3): A first resource corresponds to a second resource configured at one or more time domain locations.

Exemplarily, as shown in FIG. 7(b), the first resource includes 1 RO resource, the second resource includes 4 PO resources, and the 4 PO resources overlap in time domain position.

Or, as shown in (b) of FIG. 9, the first resource includes 1 PO resource, the second resource includes 4 RO resources, and the 4 RO resources overlap in time domain position.

Or, as shown in (a) of FIG. 7, the first resource includes 1 RO resource, the second resource includes 4 PO resources, and the 4 PO resources are configured at 2 time domain positions.

Or, as shown in Figure 7 (c) and Figure 7 (d), the first resource includes 1 RO resource, the second resource includes 4 PO resources, and the 4 PO resources are configured in 4 time domain locations .

Or, as shown in (a) of FIG. 9, the first resource includes 1 PO resource, the second resource includes 4 RO resources, and the 4 RO resources are configured at 2 time domain locations.

Or, as shown in Figure 9 (c) and Figure 9 (d), the first resource includes 1 PO resource, the second resource includes 4 RO resources, and the 4 RO resources are configured in 4 time domains. position.

In the following, based on the correspondence between the first resources and the second resources of the above three types, taking the first time threshold T=16 us as an example, the random access method in the embodiments of the present application is introduced.

Example 1:

Combine the above. As shown in S1020 in FIGS. 10A and 10B, the terminal device 300 determines whether the time domain interval t′ between the first resource and the second resource is less than the first time threshold T. Assume that the first time threshold T=16us. If t'<16us, and the corresponding relationship between the first resource and the second resource is the aforementioned type (1) corresponding relationship, that is, one first resource corresponds to one second resource. Specifically, the first resource includes an RO resource, and the second resource includes a PO resource, as shown in (a) in FIG. 5. The terminal device 300 executes S1030:

S1030. The terminal device 300 detects whether the first resource is available.

If the first resource is available (that is, an RO resource as shown in (a) in FIG. 5 is available), the terminal device performs S1031 in FIG. 10A; if the above-mentioned RO resource is not available, the terminal device 300 performs as shown in FIG. 10B S1032.

S1031. The terminal device 300 sends the first information and the second information to the base station 310.

As shown in FIG. 10A, when the terminal device 300 determines that the aforementioned one RO resource is available, the terminal device 300 may send second information to the base station 310 through the aforementioned one RO resource, and the second information includes the PRACH preamble. And the terminal device 300 sends the first information to the base station 310 through the second resource (ie, a PO resource as shown in (a) in FIG. 5), and the first information includes the PUSCH that carries the uplink data.

As shown in FIG. 10A, after the terminal device 300 performs S1031, the base station 310 performs S1034.

S1032. The terminal device 300 detects whether the second resource is available.

As shown in FIG. 10B, if the second resource is available (that is, the aforementioned one PO resource is available), the terminal device executes S1033; if the aforementioned one PO resource is unavailable, the terminal device 300 gives up sending the first information to the base station 310.

Similarly, the terminal device can determine whether the second resource is available by performing LBT on the second resource.

S1033. The terminal device 300 sends the first information to the base station 310 through the second resource.

As shown in FIG. 10B, when the terminal device 300 determines that the second resource (that is, the aforementioned one PO resource) is available, the terminal device 300 may send the first information to the base station 310. Wherein, the first information includes PUSCH, and the PUSCH carries uplink data.

After the terminal device 300 performs S1033, the base station 310 performs S1034.

S1034. The base station 310 detects the PRACH preamble and/or the base station 310 decodes the PUSCH carrying uplink data, and determines the response information sent to the terminal device 300 according to the detection and/or decoding result.

Wherein, if the terminal device 300 executes S1031 and sends the first information including the PUSCH carrying uplink data and the first information including the PRACH preamble to the base station 310, the base station 310 can detect the PRACH preamble, and the The PUSCH of the uplink data is decoded. Then, according to the detection result of the PRACH preamble and the decoding result of the PUSCH carrying the uplink data, the response information to be sent to the terminal device 300 is determined.

If the second resource (that is, the aforementioned one PO resource) is available, the terminal device 300 performs S1033 and sends the second information including the PUSCH carrying the uplink data to the base station 310, and the base station 310 can decode the PUSCH carrying the uplink data . Then, according to the decoding result of the PUSCH carrying the uplink data, the response information to be sent to the terminal device 300 is determined.

In summary, in the embodiment of the present application, the information sent by the terminal device 300 to the base station 310 has the following four situations:

Case 1: The terminal device 300 sends a PRACH preamble and a PUSCH carrying uplink data to the base station 310.

For example, when one RO resource and one PO resource are both available, the terminal device 300 sends a PRACH preamble and a PUSCH carrying uplink data to the base station 310.

Case 2: The terminal device 300 only sends the PRACH preamble to the base station 310.

For example, when the aforementioned one RO resource is available but the aforementioned one PO resource is not available, the terminal device 300 only sends the PRACH preamble to the base station 310.

Case 3: The terminal device 300 only transmits the PUSCH carrying uplink data to the base station 310.

For example, when the aforementioned one RO resource is unavailable but the aforementioned one PO resource is available, the terminal device 300 only sends the PUSCH carrying uplink data to the base station 310.

Case 4: The terminal device 300 does not send information to the base station 310.

For example, when the aforementioned one RO resource is unavailable and the aforementioned one PO resource is unavailable, the terminal device 300 does not send information to the base station 310.

The base station 310 can detect the PRACH preamble after receiving the PRACH preamble from the terminal device 300; after receiving the PUSCH carrying the uplink data from the terminal device 300, it can decode the PUSCH carrying the uplink data .

In some embodiments, for the above case 1, the base station 310 fails to detect the PRACH preamble, and fails to detect or decode the PUSCH carrying uplink data; and the base station 310 in the above case 2 only receives the PRACH preamble, and the base station When 310 fails to detect the PRACH preamble, the base station 310 does not send response information to the terminal device 300.

In some other embodiments, based on the above case 1, case 2 and case 3, if the base station 310 sends response information to the terminal device 300, the response information can be divided into the following three types:

The first type: In case 1, the base station 310 succeeds in detecting the PRACH preamble and fails to decode the PUSCH carrying uplink data; or the base station 310 in case 2 above only receives the PRACH preamble, and the base station 310 detects the PRACH preamble In the scenario of successful code detection, the base station 310 sends response information for the successful detection of the PRACH preamble to the terminal device 300, and the response information includes at least the index of the PRACH preamble.

The response information may also include at least one of the following information: uplink scheduling authorization (Uplink grant, UL grant), timing advance command (timing advance command, TA command), and temporary cell radio network temporary identifier (Temporary Cell Radio Network Temporary Identifier) , TC-RNTI).

Wherein, the TA command is a timing advance command of the base station 310 for a timing advance group (timing advance group, TAG). The TA command is used to indicate the adjustment time value of the uplink data transmission time relative to the time when the TA command is received when the terminal device 300 is performing uplink data transmission.

Taking random access under the NR system as an example, in some embodiments, it can be according to formula 1:

T _TA =(N _TA +N _TA,offset )T _c ; (Formula 1)

When the terminal device 300 is performing uplink data transmission, the adjustment time value T _{TA of the} uplink data transmission time relative to the time when the TA command is received is calculated.

In the above formula 1, N _TA =T _A ·N _u . Wherein, T _A is the TA index value, T _A may be determined according to the TA command from the base station 310. N _u is the granularity of uplink synchronization, and N _u =16×64/2 ^μ . N _TA and _offset can be defined by the high-level parameter n-TimingAdvanceOffse, or, if the n-TimingAdvanceOffset is not defined, N _TA and _offset can be preset default values. T _c =1/(Δf _max ·N _f ), Δf _max is the maximum sub-carrier spacing, Δf _max =480·10 ³ , N _f is the sampling value, and N _f =4096.

Among them, the above μ is related to the subcarrier interval Δf of uplink data transmission. Specifically, ^μ can be calculated according to the formula Δf=2 ^μ ·15.

Exemplarily, the subcarrier interval Δf of the uplink data transmission may be any one of the following:

(1) The subcarrier interval used for the first uplink transmission after the terminal device 300 receives the response information.

(2) When the terminal device 300 sends random access information to the base station 310, the subcarrier interval used when the random access information carries the PUSCH of uplink data.

(3) The maximum value of (1) and (2) above.

It should be noted that the above values of Δf _max and N _f are only taken as an example, and Δf _max and N _f may also be other values. In addition, for different wireless communication technologies, the values of Δf _max and N _f may be different. The embodiment of the application does not limit this.

It should be noted that the above method for determining the value of μ when calculating the TA adjustment value is not only applicable to the random access process in the NR-U scenario of this application, but also to the random access process in other communication systems (such as 5G NR) .

The second type: In the above case 1, the base station 310 successfully detects the PRACH preamble and successfully decodes the PUSCH carrying the uplink data; or in the above case 1, the base station 310 fails to detect the PRACH preamble and the uplink data is carried The PUSCH decoding is successful; or the base station 310 in the above case 3 only receives the PUSCH carrying uplink data, and the base station 310 successfully decodes the PUSCH carrying the uplink data, the base station 310 sends the PUSCH decoding to the terminal device 300 Successful response message.

The response information includes at least: Contention Resolution ID (CRID), and the response information may also include at least one of the following information: uplink scheduling authorization UL grant, timing advance command TA command, temporary cell radio network temporary identification TC -RNTI and RRC information, etc.

It can be understood that, in this embodiment of the present application, the PUSCH carrying uplink data sent by the terminal device 300 to the base station 310 includes information for identifying the terminal device. Exemplarily, when the terminal device 300 is in a connected state, the PUSCH of the uplink data includes a Cell Radio Network Temporary Identifier (C-RNTI); when the terminal device 300 is in an idle state or in an inactive state, The PUSCH of the uplink data includes CRID. However, since the PRACH preambles of different terminal devices will collide, in order to avoid PRACH preamble collisions, all terminal devices that receive the response information, the response information can include CRID for the terminal device to determine according to the CRID Whether the response information is for itself.

The third type: for the scenario where the base station 310 in the above case 3 only receives the PUSCH carrying uplink data, and the base station 310 fails to detect or decode the PUSCH carrying the uplink data, the base station 310 sends the PUSCH decoding to the terminal device 300 Failure response information. The response message may include PO resource indication information.

The response message may also include at least one of the following information: uplink scheduling authorization UL grant, timing advance command, TA command, and temporary cell radio network temporary identification TC-RNTI.

It should be noted that, for the above case 3, if the terminal device 300 only sends the PUSCH carrying uplink data to the base station 310. When the base station 310 receives the PUSCH carrying uplink data, it needs to first detect the demodulation reference signal DMRS sequence in the PUSCH, and perform channel estimation to obtain the channel estimation value. Then the base station 310 decodes the PUSCH according to the channel estimation value. If the channel estimation obtained by the base station 310 according to the detected DMRS sequence is inaccurate, during decoding, the PUSCH decoding may fail due to the inaccurate channel estimation. In this case, the base station 310 may also send response information to the terminal device 300. The response information may include PO resource indication information, which is used by the terminal device 300 to determine according to the PO resource indication information that the response information is a feedback of the PUSCH sent by the terminal device 300 that carries uplink data.

Wherein, PO resource indication information includes at least one or more of the following: demodulation reference signal DMRS port number corresponding to PUSCH, DMRS sequence index number corresponding to PUSCH, index number of PO resource and PUSCH resource unit index number corresponding to PUSCH .

In some embodiments, for the scenario where the base station 310 in the above case 3 only receives the PUSCH carrying uplink data, and the base station 310 fails to detect or decode the PUSCH carrying the uplink data, the base station 310 only sends the PO to the terminal device 300. Resource indication information, the response information may also include at least one of the following information: uplink scheduling grant (UL grant), timing advance command (timing advance command, TA command) and temporary cell radio network temporary identification (Temporary Cell) Radio Network Temporary Identifier, TC-RNTI).

Among them, the base station 310 notifies the terminal device 300 of the resources allocated by the base station 310 by sending a UL grant. The base station 310 notifies the terminal device 300 by sending a TA command, so that the terminal device 300 can estimate the radio frequency transmission delay caused by the distance, so as to send the uplink data packet in advance correspondingly. The base station 310 sends the TC-RNTI to the terminal device 300 to uniquely identify the terminal device 300 on the air interface.

S1035. The terminal device 300 receives response information from the base station 310. As shown in Figure 10A and Figure 10B.

S1036. The terminal device 300 performs the next operation according to the response information. As shown in Figure 10A and Figure 10B.

In some embodiments, if the response information received by the terminal device 300 from the base station 310 includes: the index of the PRACH preamble.

In this case, the terminal device 300 can compare whether the PRACH preamble indicated by the index of the PRACH preamble received from the base station 310 is the same as the PRACH preamble sent by the terminal device 300 to the base station 310. If they are the same, the terminal device 300 can determine that the response information is the feedback of the PRACH preamble sent by the base station.

In other embodiments, if the response information received by the terminal device 300 from the base station 310 includes: a contention resolution identification CRID.

If the terminal device 300 receives the contention resolution identification CRID from the base station 310, if the contention resolution identification CRID and the user information sent by the terminal device to the base station 310 (for example, the Common Control Channel (CCCH) carried in the uplink data) The service data unit (SDU) is matched, and the terminal device 300 can determine that the contention resolution is successful.

In other embodiments, if the response information received by the terminal device 300 from the base station 310 includes PO resource indication information.

As mentioned above, although the base station 310 fails to decode the PUSCH from the terminal device 300 that carries uplink data. The base station 310 may also send response information including the information indicated by the PO resource to the terminal device 300. In this case, the terminal device 300 can compare the port number and/or index number indicated by the PO resource indication information received from the base station 310 with the port number and/or index number used when the terminal device 300 sends the PUSCH carrying uplink data to the base station 310 Whether the port numbers and/or index numbers indicated by the PO resource indication information are the same. If they are the same, the terminal device 300 can determine that the response information is the base station's feedback on the PUSCH carrying uplink data. Then, the terminal device 300 can perform PUSCH transmission according to the uplink scheduling grant UL grant and other information carried in the response information without sending the PRACH preamble to the base station 310.

The transmission of the PUSCH may be the transmission of the PUSCH carrying new uplink data or the retransmission of the PUSCH carrying the uplink data that the base station 310 fails to decode, which is not limited in the embodiment of the present application.

Further, if the response information in the foregoing embodiment further includes at least one of the following information: UL grant, TA command, and TC-RNTI. The terminal device 300 can use the PUSCH time-frequency resource allocated to the terminal device 310 by the base station 310 carried in the UL grant, adjust the uplink data transmission time according to the uplink transmission time adjustment value carried in the TA command, and use the base station 310 allocated for the terminal device 300 The TC-RNTI scrambles the uplink data sent by the base station 310.

Example 2:

Combine the above. As shown in S1020 in FIGS. 10A and 10B, the terminal device 300 determines whether the time domain interval t′ between the first resource and the second resource is less than the first time threshold T. Assume that the first time threshold T=16us. If t'<16us, and the corresponding relationship between the first resource and the second resource is the aforementioned type (1) corresponding relationship, that is, one first resource corresponds to one second resource. Specifically, the first resource includes a PO resource, and the second resource includes an RO resource, as shown in FIG. 5(b). The terminal device 300 executes S1030:

If the first resource is available (that is, a PO resource as shown in (b) in FIG. 5 is available), the terminal device performs S1031 in FIG. 10A; if the above-mentioned PO resource is not available, the terminal device 300 performs as shown in FIG. 10B S1032.

S1031. The terminal device 300 sends the first information and the second information to the base station 310.

As shown in FIG. 10A, when the terminal device 300 determines that the above-mentioned one PO resource is available, the terminal device 300 may send second information to the base station 310 through the first resource, and the second information includes the PUSCH carrying uplink data. And sending the first information to the base station 310 through the second resource (that is, an RO resource as shown in (b) in FIG. 5), and the first information includes the PRACH preamble.

As shown in FIG. 10A, after the terminal device 300 performs S1031, the base station 310 performs S1034.

S1032. The terminal device 300 detects whether the second resource is available.

As shown in FIG. 10B, if the second resource is available (that is, the aforementioned one RO resource is available), the terminal device performs S1033; if the aforementioned one RO resource is not available, the terminal device 300 gives up sending the first information to the base station 310.

Similarly, the terminal device can determine whether the second resource is available by performing LBT on the second resource.

S1033. The terminal device 300 sends the first information to the base station 310 through the second resource.

As shown in FIG. 10B, when the terminal device 300 determines that the second resource (that is, the aforementioned one RO resource) is available, the terminal device 300 may send the first information including the PRACH preamble to the base station 310.

After the terminal device 300 executes S1033, the base station 310 executes S1034.

S1034. The base station 310 detects the PRACH preamble and/or the base station 310 decodes the PUSCH carrying uplink data, and determines the response information sent to the terminal device 300 according to the detection and/or decoding result.

Wherein, if the terminal device 300 executes S1031 and sends the first information including the PUSCH carrying uplink data and the second information including the PRACH preamble to the base station 310, the base station 310 can detect the PRACH preamble and detect the The PUSCH of the uplink data is decoded. Then, according to the detection result of the PRACH preamble and the decoding result of the PUSCH carrying the uplink data, the response information to be sent to the terminal device 300 is determined.

If the second resource (that is, the aforementioned RO resource) is available, the terminal device 300 performs S1033 and sends the first information including the PRACH preamble to the base station 310, and the base station 310 can detect the PRACH preamble. Then, according to the detection result of the PRACH preamble, the response information sent to the terminal device 300 is determined.

Similar to Embodiment 1, in Embodiment 2 of the present application, the information sent by the terminal device 300 to the base station 310 also has the following four situations:

Case 1: The terminal device 300 sends a PRACH preamble and a PUSCH carrying uplink data to the base station 310.

Case 2: The terminal device 300 only sends the PRACH preamble to the base station 310.

Case 3: The terminal device 300 only transmits the PUSCH carrying uplink data to the base station 310.

Case 4: The terminal device 300 does not send information to the base station 310.

The base station 310 can detect the PRACH preamble after receiving the PRACH preamble from the terminal device 300; after receiving the PUSCH carrying the uplink data from the terminal device 300, it can decode the PUSCH carrying the uplink data .

In some embodiments, for the above case 1, the base station 310 fails to detect the PRACH preamble and fails to decode the PUSCH carrying uplink data; and the base station 310 in the above case 2 only receives the PRACH preamble, and the base station 310 pairs In the scenario where the PRACH preamble detection fails, the base station 310 does not send response information to the terminal device 300.

In some other embodiments, similar to the first embodiment, based on the above case 1, case 2 and case 3, if the base station 310 sends response information to the terminal device 300, the response information in the embodiment 2 of the present application can also be divided into the following three Species:

The response information may also include at least one of the following information: uplink scheduling authorization (Uplink grant, UL grant), timing advance command (timing advance command, TA command), and temporary cell radio network temporary identifier (Temporary Cell Radio Network Temporary Identifier) , TC-RNTI).

The second type: In the above case 1, the base station 310 successfully detects the PRACH preamble and successfully detects the PUSCH carrying uplink data; or in the above case 1, the base station 310 fails to detect the PRACH preamble, and the base station 310 fails to detect the PRACH preamble and detects the uplink data. PUSCH detection is successful; or the base station 310 in the above case 3 only receives the PUSCH carrying uplink data, and the base station 310 successfully detects the PUSCH carrying uplink data, the base station 310 sends a response to the terminal device 300 for successful PUSCH decoding information.

The response message may also include at least one of the following information: uplink scheduling authorization UL grant, timing advance command, TA command, and temporary cell radio network temporary identification TC-RNTI.

S1035. The terminal device 300 receives response information from the base station 310. As shown in Figure 10A and Figure 10B.

S1036. The terminal device 300 performs the next operation according to the response information. As shown in Figure 10A and Figure 10B.

In some embodiments, if the response information received by the terminal device 300 from the base station 310 includes: the index of the PRACH preamble.

In this case, the terminal device 300 can compare whether the PRACH preamble indicated by the index of the PRACH preamble received from the base station 310 is the same as the PRACH preamble sent by the terminal device 300 to the base station 310. If they are the same, the terminal device 300 can determine that the response information is the feedback of the PRACH preamble sent by the base station.

In other embodiments, if the response information received by the terminal device 300 from the base station 310 includes: a contention resolution identification CRID.

If the terminal device 300 receives the contention resolution identification CRID from the base station 310, if the contention resolution identification CRID and the user information sent by the terminal device to the base station 310 (for example, the Common Control Channel (CCCH) carried in the uplink data) The service data unit (SDU) is matched, and the terminal device 300 can determine that the contention resolution is successful.

In other embodiments, if the response information received by the terminal device 300 from the base station 310 includes PO resource indication information.

In this case, the terminal device 300 can compare the port number and/or index number indicated by the PO resource indication information received from the base station 310 with the port number and/or index number used when the terminal device 300 sends the PUSCH carrying uplink data to the base station 310 Whether the port numbers and/or index numbers indicated by the PO resource indication information are the same. If they are the same, the terminal device 300 can determine that the response information is the base station's feedback on the PUSCH carrying uplink data. Then, the terminal device 300 can perform PUSCH transmission according to the uplink scheduling grant UL grant and other information carried in the response information without sending the PRACH preamble to the base station 310.

The transmission of the PUSCH may be the transmission of the PUSCH carrying new uplink data or the retransmission of the PUSCH carrying the uplink data that the base station 310 fails to decode, which is not limited in the embodiment of the present application.

Further, if the response information in the foregoing embodiment further includes at least one of the following information: UL grant, TA command, and TC-RNTI. The terminal device 300 can use the PUSCH time-frequency resource allocated to the terminal device 310 by the base station 310 carried in the UL grant, adjust the uplink data transmission time according to the uplink transmission time adjustment value carried in the TA command, and use the base station 310 allocated for the terminal device 300 The TC-RNTI scrambles the uplink data sent by the base station 310.

Example 3:

Combine the above. As shown in S1020 in FIG. 11, the terminal device 300 determines whether the time domain interval t′ between the first resource and the second resource is smaller than the first time threshold T. Assume that the first time threshold T=16us. If t'≥16us, and the configuration information of the first resource and the second resource indicates that the first resource includes one or more RO resources, and the second resource includes one or more PO resources. The terminal device 300 executes S1130:

S1130. The terminal device 300 detects whether the first resource is available.

If the first resource is available, the terminal device 300 executes S1131 as shown in FIG. 11. If the first resource is not available, the terminal device 300 executes S1132 as shown in FIG. 11.

Similarly, the terminal device can determine whether the first resource is available by performing LBT on the first resource.

In some embodiments, the same as embodiment 1, when the first resource includes one RO resource, if the one RO resource is available, the first resource is available; if the one RO resource is not available, the first resource is not available use.

In other embodiments, when the first resource includes multiple RO resources, if at least one RO resource of the multiple RO resources is available, the first resource is available; if each RO resource of the multiple RO resources If neither is available, the first resource is unavailable.

The following describes the specific process of the terminal device 300 detecting whether the first resource is available (ie S1130) based on the corresponding relationship between the first resource and the second resource of the aforementioned types (1), (2), and (3).

(1). For the corresponding relationship between the first resource and the second resource of the aforementioned types (1) and (3), the first resource (including one RO resource) corresponds to the second resource configured in at least one time domain location (Including one or more PO resources).

Exemplarily, when the first resource includes 1 RO resource ((a) in Figure 5, (a) in Figure 7, (b) in Figure 7, (c) in Figure 7, and in Figure 7 (D)). In this case, the terminal device 300 detects whether the first resource is available, including: the terminal device 300 performs LBT detection on the first resource, and if the RO resource is available, the first resource is available The terminal device performs S1131 in FIG. 11; if the one RO resource is not available, the first resource is not available, and the terminal device 300 performs S1132 in FIG. 11.

(2) For the correspondence between the first resource and the second resource in the above-mentioned category (2), the first resource (including multiple RO resources) configured in a time domain position corresponds to the second resource including one PO resource.

Exemplarily, the first resource includes 4 RO resources, and the second resource includes 1 PO resource, and the multiple RO resources are configured in a time domain position (as shown in (b) of FIG. 6). In this case, the terminal device 300 detecting whether the first resource is available includes: the terminal device 300 detects whether the aforementioned multiple RO resources are available by performing LBT on the first resource. If at least one RO resource among the multiple RO resources is available, the first resource is available, and the terminal device 300 executes S1131. If none of the multiple RO resources are available, the first resource is not available, and the terminal device 300 executes S1132.

(3) For the correspondence between the first resource and the second resource in the above-mentioned category (2), the first resource including multiple RO resources configured in multiple time domain locations corresponds to the second resource including one PO resource.

Exemplarily, the first resource includes 4 RO resources, and the 4 RO resources are respectively configured in at least two time domain positions ((a) in FIG. 6, (c) in FIG. 6, and ( d) shown). In this case, the terminal device 300 detecting whether the first resource is available includes: the terminal device 300 detecting whether the RO resource at the first time domain location is available. If at least one RO resource among the RO resources at the first time domain location is available, the terminal device 300 determines that the first resource is available. If all RO resources at the first time domain location are unavailable, the terminal device 300 detects whether the RO resources at the second time domain location are available, and so on. Use the above method. Wherein, the time domain position of the second time domain position is after the first time domain position.

Specifically to the corresponding relationship shown in (a) in FIG. 6, the terminal device 300 detects whether the first resource is available, including: the terminal device 300 detects whether RO1 and RO0 are available by performing LBT on RO1 and RO0 at the first time domain location . If at least one of RO1 and RO0 is available, the terminal device 300 determines that the first resource is available, and the terminal device 300 executes S1131. If both RO1 and RO0 are unavailable, the terminal device 300 can detect whether RO2 and RO3 configured at a second time domain location after the first time domain location are available. If RO2 or RO3 is available, the terminal device 300 determines that the first resource is available, and the terminal device 300 executes S1131. If RO2 and RO3 are not available, the terminal device 300 determines that the first resource is not available, and the terminal device 300 executes S1132.

S1131. The terminal device 300 sends second information to the base station 310 through the first resource.

Wherein, the second information includes PRACH preamble. In some embodiments, if the first resource includes an RO resource (as shown in Figure 5(a), Figure 7(a), Figure 7(b), Figure 7(c)) and Figure 7 As shown in (d)), the terminal device 300 sends the second information including the PRACH preamble to the base station 310 through the one RO resource.

In other embodiments, if the first resource includes multiple RO resources (as shown in (a) in Figure 6, (b) in Figure 6, (c) in Figure 6, and (d) in Figure 6) (Shown), the terminal device 300 sends the second information including the PRACH preamble to the base station 310 through one of the available RO resources of the multiple RO resources.

Wherein, the terminal device 300 may send the second information including the PRACH preamble to the base station 310 through the RO resource available in any one of the multiple RO resources. Alternatively, the terminal device 300 may also select any available RO resource from a plurality of RO resources according to a preset rule and send the second information including the PRACH preamble to the base station 310.

Exemplarily, the preset rule may be that the terminal device may determine the threshold value configured by the base station according to the reference signal received power (Reference Signal Received Power, RSRP) of the synchronization signal block (synchronization signal block, SSB) corresponding to the multiple RO resources By comparison, an available RO resource is selected from the multiple RO resources to send the PRACH preamble to the base station 310.

It can be understood that, because different synchronization signal blocks SSB can be associated with different RO resources. When multiple ROs are available, specifically, the terminal device may first determine one SSB according to the RSRP of the SSB corresponding to the multiple ROs, for example, the RSRP of the one SSB is the largest. Then, the terminal device may determine to send the PRACH preamble to the base station 310 through the RO associated with the SSB.

After the terminal device 300 performs S1131, the terminal device 300 may continue to perform S1132.

S1132. The terminal device 300 detects whether the second resource is available.

If the second resource is available, as shown in FIG. 11, the terminal device executes S1133. If the second resource is not available, the terminal device 300 gives up sending the first information to the base station 310.

Similarly, the terminal device can determine whether the second resource is available by performing LBT on the second resource.

The same as Embodiment 1, when the second resource includes one PO resource, if the one PO resource is available, the second resource is available; if the one PO resource is unavailable, the second resource is unavailable.

In other embodiments, when the second resource includes multiple PO resources, if at least one PO resource in the multiple PO resources is available, then the second resource is available; if each PO resource in the multiple PO resources is available If neither is available, the second resource is unavailable.

For the specific process for the terminal device 300 to detect whether the second resource is available, reference may be made to step S1032 in Embodiment 1 to introduce the specific process for the terminal device 300 to detect whether the second resource is available. The embodiments of this application will not be repeated here.

S1133. The terminal device 300 sends the first information to the base station 310 through the second resource.

The first information includes PUSCH, and the PUSCH carries uplink data.

In some embodiments, if the second resource includes a PO resource (as shown in Figure 5 (a), Figure 6 (a), Figure 6 (b), Figure 6 (c) and Figure 6 As shown in (d)), if the second resource is available, the terminal device 300 transmits the PUSCH carrying uplink data to the base station 310 through the one PO resource.

In other embodiments, if the second resource includes multiple PO resources (as shown in (a) in Figure 7, (b) in Figure 7, (c) in Figure 7, and (d) in Figure 7) If the second resource is available, the terminal device 300 sends the PUSCH carrying uplink data to the base station 310 through one of the available PO resources among the multiple PO resources.

Similarly, the terminal device 300 may send the PUSCH carrying uplink data to the base station 310 through the available PO resource in any one of the multiple PO resources. Alternatively, the terminal device 300 may also select any available PO resource from a plurality of PO resources according to a preset rule to send the PUSCH carrying uplink data to the base station 310.

S1134. The base station 310 detects the PRACH preamble and/or the base station decodes the PUSCH carrying uplink data, and determines the response information sent to the terminal device 300 according to the detection and/or decoding result.

Similar to Embodiment 1 and Embodiment 2, in Embodiment 3 of the present application, the information sent by the terminal device 300 to the base station 310 also has the following four situations:

Case 1: The terminal device 300 sends a PRACH preamble and a PUSCH carrying uplink data to the base station 310.

Case 2: The terminal device 300 only sends the PRACH preamble to the base station 310.

Case 3: The terminal device 300 only transmits the PUSCH carrying uplink data to the base station 310.

Case 4: The terminal device 300 does not send information to the base station 310. For example, when the first resource (one or more RO resources) is unavailable, and the second resource (one or more PO resources) is unavailable, the terminal device 300 does not send information to the base station 310.

(1). Regarding the corresponding relationship between the first resource and the second resource of the aforementioned types (1) and (3), the first resource (including one PO resource) corresponds to the second resource configured in at least one time domain location (Including one or more RO resources).

Exemplarily, when the first resource includes 1 PO resource ((b) in Figure 5, (a) in Figure 9, (b) in Figure 9, (c) in Figure 9, and in Figure 9 (D)).

In this case, the terminal device 300 detecting whether the first resource is available includes: the terminal device 300 detects whether the aforementioned multiple PO resources are available by performing LBT on the first resource. If at least one PO resource among the multiple PO resources is available, the first resource is available, and the terminal device 300 executes S1131. If none of the multiple PO resources are available, the first resource is not available, and the terminal device 300 executes S1132.

(3) For the correspondence between the first resource and the second resource in the above-mentioned category (2), the first resource including multiple PO resources configured in multiple time domain locations corresponds to the second resource including one RO resource.

Exemplarily, the first resource includes 4 PO resources, and the 4 PO resources are respectively configured in two time domain positions ((a) in FIG. 8, (c) in FIG. 8, and (d) in FIG. ) Shown). In this case, the terminal device 300 detecting whether the first resource is available includes: the terminal device 300 detecting whether the PO resource at the first time domain location is available. If at least one PO resource among the PO resources at the first time domain location is available, the terminal device 300 determines that the first resource is available. If all the PO resources in the first time domain location are unavailable, the terminal device 300 detects whether the PO resources in the second time domain location are available, and so on.
