Description

Technical Field

[0001] The present disclosure relates to the field of communications, and in particular to a method and device for determining a random access channel opportunity (RO). Background Art

[0002] In the NR (New Radio) system, the terminal can access the gNB (base station) using a four-step random access method or a two-step random access method.

[0003] Among them, the four-step random access method is as follows Figure 1A As shown, the terminal sends msg1 to gNB, and msg1 includes a random access preamble. The msg2 replied by gNB carries the time domain resource and frequency domain resource parameters of msg3, and allocates TC-RNTI (Temporary Cell Radio Network Temporary Identity) to the terminal to achieve uplink synchronization between the terminal and gNB. At the same time, in order to resolve the conflict, the terminal scrambles msg3 with TC-RNTI and sends msg3 to gNB. The gNB replies msg4 to obtain C-RNTI. After receiving, the terminal replaces TC-RNTI with C-RNTI.

[0004] A two-step random access method is proposed in R16 (Release 16), for example Figure 1B As shown in the figure, msg1 and msg3 are combined into msgA, and msg2 and msg4 are combined into msgB. Among them, msgA includes a random access preamble and a payload.

[0005] At present, although the terminal can access the gNB using the four-step random access method or the two-step random access method, how the terminal chooses to send RO (Random Access Channel Occasion) has not yet been implemented. Summary of the invention

If the load value is less than the preset threshold and the terminal is not in the target state, the RO on the terminal access network side is determined to be the second preset RO with high availability.

[0080] In the disclosed embodiment, the time period corresponding to the first preset RO is divided into a first time period and a second time period arranged in sequence, the first time period only allows the sending of a random access preamble corresponding to the first random access method, and the second time period only allows the sending of a random access preamble corresponding to the second random access method, then the terminal can send a random access preamble in the time period corresponding to the random access method adopted by itself, that is, in the first time period or the second time period, thereby accessing the network side. The time period corresponding to the second preset RO allows the sending of a random access preamble corresponding to any random access method, and accordingly, the terminal can send a random access preamble in the time period corresponding to the second preset RO, thereby accessing the network side.

Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0109] In the RAN1 (Radio Access Network 1, Radio Access Layer 1) meeting, the RO corresponding to the two-step random access and four-step random access methods was proposed:

[0110] In the first mode (first preset RO), the ROs of two-step random access and four-step random access are independent.

[0111] That is to say, the time period corresponding to the RO is divided into a first time period and a second time period arranged in sequence, and in the first time period, only terminals using the two-step random access method are allowed to send random access preambles, and in the second time period, only terminals using the four-step random access method are allowed to send random access preambles. Or conversely, in the first time period, only terminals using the four-step random access method are allowed to send random access preambles, and in the second time period, only terminals using the two-step random access method are allowed to send random access preambles, such as Figure 2A shown.

[0112] In the second mode (second preset RO), the RO of the two-step random access and the RO of the four-step random access are shared.

[0113] That is to say, within the time period corresponding to the RO, both terminals using the two-step random access method and terminals using the four-step random access method are allowed to send random access preambles. For example, Figure 2B shown.

[0114] In the disclosed embodiment, the RO in the first manner is used as the first preset RO, and the RO in the second manner is used as the second preset RO. However, the terminal cannot select which manner to use to send the random access preamble.

[0115] In order to solve the above problem, the embodiment of the present disclosure provides a method for determining a random access channel opportunity RO, which can be used for a terminal, as shown in FIG. 3. Figure 3 FIG. 4 is a flow chart of a method for determining a random access channel opportunity RO according to an embodiment. The method may include the following steps:

[0116] In step 101, a load value of a physical uplink shared channel PUSCH of a base station that has accessed the base station is received and broadcasted by the base station.

[0117] In this step, the base station may count the load value of the PUSCH (Physical Uplink Shared Channel) that has accessed the base station, and broadcast it to the terminal through the PBCH (Physical Broadcast Channel). After receiving the load value, the terminal may determine the load value.

[0118] In step 102, a random access channel opportunity RO for the terminal to access the network side is determined according to the load value.

[0119] In this step, the terminal can determine the RO according to the load value of the PUSCH of the connected base station. Optionally, if the load value is high, the terminal can use the first preset RO as its own RO, and if the load value is not high, the terminal can use the second preset RO as its own RO.

[0120] In the above embodiment, the terminal can determine the random access channel opportunity RO of the terminal access network side according to the load value of the physical uplink shared channel PUSCH broadcast by the base station that has accessed the base station, thereby achieving the purpose of determining the RO of the terminal access network side.

[0121] In one embodiment, when the load value is greater than or equal to a preset threshold, the terminal may consider that the load value is high. At this time, the terminal may adopt the first preset RO as its own RO.

[0122] For example, in the first time period corresponding to the first preset RO, only the terminal using the two-step random access method is allowed to send the random access preamble code, and in the second time period, only the terminal using the four-step random access method is allowed to send the random access preamble code. If the terminal currently uses the four-step random access method, the terminal needs to send the random access preamble code to the base station in the second time period.

[0123] In addition, when the load value is less than a preset threshold, the terminal may consider that the load value is low, and at this time the terminal may adopt the second preset RO as its own RO.

[0124] For example, no matter whether the terminal currently adopts a two-step random access method or a four-step random access method, the terminal can send a random access preamble code to the base station within the entire time period corresponding to the second preset RO.

[0125] In the above embodiment, if the load value is greater than or equal to the preset threshold, the terminal may determine the RO on the access network side as the first preset RO, otherwise the RO on the access network side is determined as the second preset RO. The implementation is simple and the availability is high.

[0126] In one embodiment, referring to FIG. 4, Figure 4 is based on Figure 3 The embodiment shown is a flow chart of another method for determining a random access channel opportunity RO, the method further comprising:

[0127] In step 103, the current state of the terminal is determined.

[0128] Optionally, the current state of the terminal may be a target state, that is, the terminal is in a connected state, including that the terminal and the network side are in an uplink out-of-sync state, uplink and downlink synchronization requires the network side to release SR (scheduling request) resources, and handover. Or the current state of the terminal may be initial Access (initial random access state).

[0129] In step 104, the RO of the network side to which the terminal accesses is determined according to the load value and the current state of the terminal.

[0130] In this step, the terminal can determine that the RO on the network side accessed by the terminal is the first preset RO when the load value is high, that is, the load value is greater than or equal to the preset threshold, and the terminal is in the above-mentioned target state. If the load value is low, the load value is less than the preset threshold, and the terminal is not in the target state, for example, in initial access, it can be determined that the RO on the network side accessed by the terminal is the second preset RO.

[0131] If the terminal is in the target state, after sending the random access preamble, the terminal needs to send the payload again, and the existing C-RNTI needs to be scrambled with RA-RNTI (Random Access Radio Network Temporary Identifier). If the terminal is in the initial random access state, there is no C-RNTI.

[0132] In the above embodiment, the terminal may further determine the current state, and thereby determine the RO of the terminal access network side according to the load value and the current state, thereby also achieving the purpose of determining the RO of the terminal access network side.

[0133] In one embodiment, referring to Figure 5, Figure 5 is based on Figure 3 The embodiment shown is a flow chart of another method for determining a random access channel opportunity RO. Before executing step 101, the method further includes:

[0134] In step 100-1, a resource parameter corresponding to an uplink random access channel PRACH opportunity is received and sent by the base station through a target SIB.

[0135] In the embodiment of the present disclosure, the target SIB (system info block) may be SIB1 used to send the resource parameters in the related art, or may be other SIBs specified in the new NR standard.

[0136] The terminal can maintain downlink synchronization with the base station according to the SSB (Synchronization Signal Block) sent by the base station, and further determine the resource parameters corresponding to the uplink random access channel PRACH opportunity according to the target SIB sent by the base station, that is, determine the resource parameters for the terminal to send RO according to the target SIB. Optionally, the resource parameters include but are not limited to time domain resource parameters and frequency domain resource parameters.

[0137] In step 100-2, a random access preamble code corresponding to the RO at which the terminal accesses the network side and a format of the random access preamble code corresponding to the RO are determined according to the resource parameters.

[0138] In this step, the terminal may determine the random access preamble code corresponding to sending the RO and the format of the random access preamble code according to the above resource parameters.

[0139] In the above embodiment, the terminal can receive the resource parameters corresponding to the uplink random access channel PRACH opportunity sent by the base station through the target SIB, and thus determine the random access preamble code corresponding to the RO when the terminal accesses the network side and the format of the random access preamble code corresponding to the RO according to the resource parameters, thereby further achieving the purpose of determining the RO of the access network side on the terminal side.

[0140] The embodiment of the present disclosure provides another method for determining a random access channel opportunity RO, the method can be used in a base station, as shown in FIG6 , Figure 6 FIG. 4 is a flow chart of another method for determining a random access channel opportunity RO according to an embodiment. The method may include the following steps:

[0141] In step 201, a load value of a physical uplink shared channel PUSCH of a base station that has accessed the base station is determined.

[0142] In this step, the base station may automatically count the load value of the PUSCH sent by the terminal side that has accessed the base station within a preset time period.

[0143] In step 202, the load value is broadcast to the terminal, and the terminal determines a random access channel opportunity RO for the terminal to access the network side according to the load value.

[0144] In this step, the base station may broadcast the load value to the terminal, and the terminal may determine the RO to access the network side according to the load value.

[0145] In the above embodiment, the base station can determine the load value of the PUSCH that has accessed itself, and broadcast the load value to the terminal, and the terminal determines the random access channel opportunity RO for the terminal to access the network side according to the load value, thereby achieving the purpose of the terminal determining the RO.

[0146] In one embodiment, the base station may count the number of random access preambles received by the base station within a preset time period, and use the number of random access preambles received as the load value of the PUSCH.

[0147] Furthermore, the base station can count the number of times the random access preamble has been received within a preset time period and the base station has replied to the msgB message but has not received the msgA payload message. In other words, the base station counts the number of random preambles sent by the terminal using the two-step access method.

[0148] In addition, the base station can also count the number of times the random access preamble has been received within a preset time period and the base station has replied to the msg2 message but has not received the msg3 message, that is, count the number of random preambles sent by the terminal using the four-step access method.

[0149] The base station uses the number of random preamble codes sent by the terminal using the two-step access method and / or the number of random preamble codes sent by the terminal using the four-step access method as the final PUSCH load value.

[0150] In the above embodiment, the base station can automatically count the load value of the PUSCH that has accessed the base station, and the availability is high.

[0151] In one embodiment, the base station may broadcast the load value to the terminal through the PBCH.

[0152] In the above embodiment, the base station may broadcast the load value to the terminal via the physical broadcast channel PBCH, so that the terminal can subsequently determine the RO according to the load value.

[0153] In one embodiment, referring to FIG. 7, Figure 7 FIG. 4 is a flow chart of another method for determining a random access channel opportunity RO according to an embodiment. The method may include the following steps:

[0154] In step 301, the base station sends resource parameters corresponding to uplink random access channel PRACH opportunities via a target SIB.

[0155] Optionally, the target SIB may be SIB1 used to send the resource parameter in the related art, or may be other SIBs specified in the new NR standard. Resource parameters include but are not limited to time resource parameters and frequency domain resource parameters.

[0156] In step 302, the terminal determines, according to the resource parameters, a random access preamble corresponding to the RO at which the terminal accesses the network side and a format of the random access preamble corresponding to the RO.

[0157] In step 303, the base station counts the number of random access preamble codes received by the base station within a preset time period.

[0158] Optionally, the base station counts the number of times the base station has received a random access preamble code within a preset time period, and the base station has replied to a msgB message but has not received a msgA payload message; and / or counts the number of times the base station has received a random access preamble code within a preset time period, and the base station has replied to a msg2 message but has not received a msg3 message.

[0159] In step 304, the base station broadcasts the load value to the terminal via a physical broadcast channel PBCH.

[0160] In step 305, if the load value is greater than or equal to a preset threshold, the terminal determines that the RO on the terminal access network side is a first preset RO; if the load value is less than the preset threshold, the terminal determines that the RO on the terminal access network side is a second preset RO.

[0161] Among them, the time period corresponding to the first preset RO is divided into a first time period and a second time period arranged in sequence, the first time period only allows the sending of a random access preamble code corresponding to the first random access method, and the second time period only allows the sending of a random access preamble code corresponding to the second random access method; the time period corresponding to the second preset RO allows the sending of a random access preamble code corresponding to any random access method.

[0162] In the above embodiment, the terminal can determine the random access channel opportunity RO of the terminal access network side according to the load value of the physical uplink shared channel PUSCH broadcast by the base station that has accessed the base station, thereby achieving the purpose of determining the RO of the terminal access network side.

[0163] In one embodiment, referring to FIG8 , Figure 8FIG. 4 is a flow chart of another method for determining a random access channel opportunity RO according to an embodiment. The method may include the following steps:

[0164] In step 401, the base station sends resource parameters corresponding to uplink random access channel PRACH opportunities via a target SIB.

[0165] Optionally, the target SIB may be SIB1 used to send the resource parameter in the related art, or may be other SIBs specified in the new NR standard. Resource parameters include but are not limited to time resource parameters and frequency domain resource parameters.

[0166] In step 402, the terminal determines, according to the resource parameters, a random access preamble corresponding to the RO at which the terminal accesses the network side and a format of the random access preamble corresponding to the RO.

[0167] In step 403, the base station counts the number of random access preamble codes received by the base station within a preset time period.

[0168] Optionally, the base station counts the number of times the base station has received a random access preamble code within a preset time period, and the base station has replied to a msgB message but has not received a msgA payload message; and / or counts the number of times the base station has received a random access preamble code within a preset time period, and the base station has replied to a msg2 message but has not received a msg3 message.

[0169] In step 404, the base station broadcasts the load value to the terminal via a physical broadcast channel PBCH.

[0170] In step 405, the terminal determines the current state of the terminal.

[0171] In step 406, if the load value is greater than or equal to a preset threshold and the terminal is in a target state, the terminal determines that the RO on the terminal access network side is a first preset RO; if the load value is less than the preset threshold and the terminal is not in the target state, the terminal determines that the RO on the terminal access network side is a second preset RO.

[0172] Among them, the time period corresponding to the first preset RO is divided into a first time period and a second time period arranged in sequence, the first time period only allows the sending of a random access preamble code corresponding to the first random access method, and the second time period only allows the sending of a random access preamble code corresponding to the second random access method; the time period corresponding to the second preset RO allows the sending of a random access preamble code corresponding to any random access method.

[0173] The target state is the connection state, including the terminal and the network side being in an uplink out-of-sync state, uplink and downlink synchronization requiring the network side to release SR (scheduling request) resources, and handover. Or the current state of the terminal may be initial access.

[0174] In the above embodiment, the terminal may further determine the current state, and thereby determine the RO of the terminal access network side according to the load value and the current state, thereby also achieving the purpose of determining the RO of the terminal access network side.
