Description

[Technical field]

[0001] The present disclosure relates to the field of wireless communication technology, and in particular to a resource conflict handling method, apparatus and readable storage medium. [Background technology]

[0002] In wireless communication technology, for example, in 5th Generation Mobile Communication Technology (5G), when User Equipment (UE) performs random access, it may adopt a 4-step Random Access Channel (RACH) process or a 2-step RACH process.

[0003] In some embodiments, the four-step RACH process comprises: The UE sends a message 1 to the base station, where the UE may send the message 1 using a preamble, where the preamble may be referred to as a RACH preamble, a Physical Random Access Channel (PRACH) preamble or a sequence; The UE receiving a message 2 from the base station; the UE sending a message 3 to the base station, where the message 3 may be a Radio Resource Control (RRC) connection request message to respond to receiving the message 2 from the base station; The UE receiving a message 4 from the base station, where if the base station successfully receives and / or decodes the message 3, the message 4 may be a contention resolution message from the base station; The UE synchronizes with the base station using the above four-step RACH process.

[0004] A two-step RACH process can combine multiple RACH messages from a four-step RACH process. For example, a two-step RACH process can include msg.A, which combines msg.1 and msg.3 from the four-step RACH process, and msg.B, which combines msg.2 and msg.4 from the four-step RACH process.

[0005] Here, a multiple blind repeat transmission method is adopted for msg.3 to increase redundant bit information, reduce the code rate, and improve the reliability of transmission.

[0006] In order to make the actual number of blind repeat transmissions match the number of repeat transmissions instructed by the base station as closely as possible and to increase the probability of success, in some embodiments, the blind repeat transmissions are counted based on available slots rather than on consecutive physical slots.

[0007] The blind repeated transmission of msg.3 may collide with the PRACH transmitted by other terminals or the PUSCH channel of msg.A transmitted by other terminals, thereby causing mutual interference between different channel transmissions of different terminals, and ultimately causing both to fail random access.

[0051] An embodiment of the present disclosure provides a resource conflict processing method performed by a first user equipment, and FIG. 2 is a flowchart of a resource conflict processing method shown by an exemplary embodiment. As shown in FIG. 2, the method includes the following steps:

[0052] In step S201, determine at least one time domain unit corresponding to an overlapping resource between a resource for repeatedly transmitting a first uplink message and a resource of a physical channel of a second uplink message, where the first uplink message is message 3 (msg.3) and the second uplink message is message 1 (msg.1) or message A (msg.A).

[0053] In step S202, the first uplink message and the second uplink message are not transmitted simultaneously by the second user equipment and the at least one time domain unit.

[0054] In some possible embodiments, the time domain unit is a symbol, a half slot or a slot.

[0055] In some possible embodiments, the physical channel of the second uplink message is: A Physical Random Access Channel (PRACH); A Physical Uplink Shared Channel (PUSCH).

[0056] In some possible embodiments, the second user equipment is any user equipment other than the first user equipment in the cell in which the first user equipment is located.

[0057] In some possible embodiments, the second user equipment is a user equipment other than the first user equipment in the cell in which the first user equipment is located, which satisfies a set condition.

[0058] In some possible embodiments, a complete overlap is configured between the resources for the repeated transmission of the first uplink message and the resources of the physical channel of the second uplink message.

[0059] In some possible embodiments, a partial overlap is configured between the resources for the repeated transmission of the first uplink message and the resources of the physical channel of the second uplink message.

[0060] In some possible embodiments, at least one time domain unit is a consecutive time domain unit.

[0061] In some possible embodiments, at least one time domain unit is a discontinuous time domain unit.

[0062] In some possible embodiments, the first uplink message is a first uplink random access message and the second uplink message is a second uplink random access message.

[0063] In an embodiment of the present disclosure, a time domain corresponding to the overlapping resource between the resource for repeatedly transmitting the first uplink message and the resource of the physical channel of the second uplink message is determined, and the current user does not transmit the first uplink message and the second uplink message simultaneously with other user equipment in this time domain, thereby avoiding resource collision between different uplink messages, reducing the interference in the channel transmission of different user equipment, and improving the success rate of random access of the user equipment.

[0064] An embodiment of the present disclosure provides a resource conflict processing method performed by a first user equipment, and FIG. 3 is a flowchart of a resource conflict processing method shown by an exemplary embodiment. As shown in FIG. 3, the method includes the following steps:

[0065] In step S301, determine at least one time domain unit corresponding to an overlapping resource between a resource for repeatedly transmitting a first uplink message and a resource of a physical channel of a second uplink message, where the first uplink message is message 3 (msg.3) and the second uplink message is message 1 (msg.1) or message A (msg.A).

[0066] In step S302, determine that the available time domain unit does not include the at least one time domain unit, and determine resources for repeatedly transmitting the first uplink message based on the available time domain unit, or calculate the number of repeated transmissions based on the available time domain unit.

[0067] In step S303, the first uplink message is not transmitted in the at least one time domain unit.

[0068] In some possible embodiments, the time domain unit is a symbol, a half slot or a slot.

[0069] In some possible embodiments, the physical channel of the second uplink message includes at least one of a PRACH and a PUSCH.

[0070] In some possible embodiments, a complete overlap is configured between the resources for the repeated transmission of the first uplink message and the resources of the physical channel of the second uplink message.

[0071] In some possible embodiments, a partial overlap is configured between the resources for the repeated transmission of the first uplink message and the resources of the physical channel of the second uplink message.

[0072] In some possible embodiments, at least one time domain unit is a consecutive time domain unit.

[0073] In some possible embodiments, at least one time domain unit is a discontinuous time domain unit.

[0074] In some possible embodiments, the first uplink message is a first uplink random access message and the second uplink message is a second uplink random access message.

[0075] In some possible embodiments, the step of determining at least one time domain unit corresponding to overlapping resources between resources for repeatedly transmitting the first uplink message and resources of a physical channel of the second uplink message in step S301 includes the following steps S301-1 to S301-3.

[0076] At S301-1, a first resource in a resource set to be used when transmitting a second uplink message is determined.

[0077] In S301-2, a second resource in the resource set is determined, where an SSB index mapped by the second resource is the same as an SSB index mapped by the first resource.

[0078] In S301-3, at least one time domain unit corresponding to an overlapping resource between the second resource and a resource for repeatedly transmitting a first uplink message is determined.

[0079] In one example, as shown in Figure 4, the resource set used for transmitting PRACH includes several time domain periods, and the eight occasions for transmitting PRACH included in one period include RO#0, RO#1, RO#2...RO#7. Here, RO#0 and RO#4 in each period are both mapped to SSB#0. When the UE transmits PRACH based on RO#0 in a certain period, in the subsequent period of this resource set, the resource occupied by the RO having the same SSB index (SSB#0) as RO#0 selected by the UE to initiate RACH and the blind repeat transmission resource of msg.3 are overlapped as at least one time domain unit.

[0080] In some possible embodiments, step S301-0 is further included before step S301-1, receiving configuration information sent from the network device, where the configuration information indicates a resource set to be used when sending the second uplink message.

[0081] In some possible embodiments, when it is determined that at least one time domain unit is a time domain unit that cannot be used for repeated transmission of the first uplink message, and the first user equipment determines resources for repeatedly transmitting the first uplink message and calculates the number of repeated transmissions, the time domain unit that cannot be used for repeated transmission of the first uplink message is not taken into account.

[0082] For example, if the time domain unit is a slot and the first uplink message is msg.3, it is determined that at least one slot corresponding to the overlapping resource is unavailable for repeated transmission of the first uplink message (unavailable slots for msg.3 repetitions), and when the first user equipment determines resources for repeatedly transmitting msg.3 and calculates the number of repeated transmissions, the unavailable slots for msg.3 repetitions are not taken into account.

[0083] For example, if the time domain unit is a symbol and the first uplink message is msg.3, it is determined that at least one symbol corresponding to the overlap resource is unavailable for repeated transmission of the first uplink message (unavailable symbols for msg.3 repetitions), and when the first user equipment determines resources for repeated transmission of msg.3 and calculates the number of repeated transmissions, the unavailable symbols for msg.3 repetitions are not taken into account.

[0084] In an embodiment of the present disclosure, the transmission of the second uplink message has a higher priority, and the transmission of the first uplink message has a lower priority; it is determined that the time domain corresponding to the overlapping resource is unavailable for repeated transmission of the first uplink message; when determining the resource for repeatedly transmitting the first uplink message and calculating the number of repeated transmissions, the above unavailable time domain is not taken into consideration, and the first uplink message is not transmitted in the at least one time domain unit, thereby ensuring the accuracy of the parameter determination and the priority of other user equipment other than the first user equipment to smoothly transmit the second uplink message, and the resource collision between different uplink messages is further avoided, the interference in the channel transmission of different user equipment is reduced, and the success rate of random access of the user equipment is improved.

[0085] An embodiment of the present disclosure provides a resource conflict processing method performed by a first user equipment, and FIG. 5 is a flowchart of a resource conflict processing method shown by an exemplary embodiment. As shown in FIG. 5, the method includes the following steps:

[0086] In step S501, determine at least one time domain unit corresponding to an overlapping resource between a resource for repeatedly transmitting a first uplink message and a resource of a physical channel of a second uplink message, where the first uplink message is message 3 (msg.3) and the second uplink message is message 1 (msg.1) or message A (msg.A).

[0087] In step S502, determine that the available time domain unit includes the at least one time domain unit, and determine resources for repeatedly transmitting the first uplink random access message based on the available time domain unit, or calculate the number of repeated transmissions based on the available time domain unit.

[0088] In step S503, the first uplink message is not transmitted in the at least one time domain unit.

[0089] In some possible embodiments, the time domain unit is a symbol, a half slot or a slot.

[0090] In some possible embodiments, the physical channel of the second uplink message includes at least one of a PRACH and a PUSCH.

[0091] In some possible embodiments, a complete overlap is configured between the resources for the repeated transmission of the first uplink message and the resources of the physical channel of the second uplink message.

[0092] In some possible embodiments, a partial overlap is configured between the resources for the repeated transmission of the first uplink message and the resources of the physical channel of the second uplink message.

[0093] In some possible embodiments, at least one time domain unit is a consecutive time domain unit.

[0094] In some possible embodiments, at least one time domain unit is a discontinuous time domain unit.

[0095] In some possible embodiments, the first uplink message is a first uplink random access message and the second uplink message is a second uplink random access message.

[0096] In some possible embodiments, it is determined that at least one time domain unit is a time domain unit usable for repeated transmission of the first uplink message, and when the first user equipment determines resources for repeatedly transmitting the first uplink message and calculates the number of repeated transmissions, it takes into account the at least one time domain unit, but does not transmit the first uplink message in the at least one time domain unit.

[0097] For example, if the time domain unit is a slot and the first uplink message is msg.3, it determines that at least one slot corresponding to the overlap resource is available for repeated transmission of the first uplink message (available slots for msg.3 repetitions), and when the first user equipment determines resources for repeatedly transmitting msg.3 and calculates the number of repeated transmissions, it takes into account the available slots for msg.3 repetitions, but does not transmit msg.3 in the at least one time domain unit.

[0098] For example, if the time domain unit is a symbol and the first uplink message is msg.3, it is determined that at least one symbol corresponding to the overlap resource is an unavailable symbol for repeated transmission of the first uplink message (unavailable symbols for msg.3 repetitions), and when the first user equipment determines resources for repeated transmission of msg.3 and calculates the number of repetitions, it takes into account the unavailable symbols for msg.3 repetitions, but does not transmit msg.3 in the at least one time domain unit.

[0099] In an embodiment of the present disclosure, the transmission of the second uplink message has a higher priority, and the transmission of the first uplink message has a lower priority; it is determined that the time domain corresponding to the overlapping resource is unavailable for repeated transmission of the first uplink message; when determining the resource for repeatedly transmitting the first uplink message and calculating the number of repeated transmissions, the above unavailable time domain is still taken into consideration, but the first uplink message is not transmitted in the at least one time domain unit, thereby ensuring compatibility with existing protocols and the priority of other user equipment other than the first user equipment to smoothly transmit the second uplink message, and the resource collision between different uplink messages is further avoided, the interference in the channel transmission of different user equipment is reduced, and the success rate of random access of the user equipment is improved.

[0101] In step S601, determine at least one time domain unit corresponding to an overlapping resource between a resource for repeatedly transmitting a first uplink message and a resource of a physical channel of a second uplink message, where the first uplink message is message 3 (msg.3) and the second uplink message is message 1 (msg.1) or message A (msg.A).

[0102] In step S602, determine an invalid random access occasion (RO) in a resource of the physical channel, where the at least one time domain unit includes the invalid RO.

[0103] In step S603, in response to the second user equipment not transmitting a second uplink message in the invalid RO, the first user equipment transmits a first uplink message in the invalid RO.

[0104] In some possible embodiments, in step S603, a first user equipment transmits a first uplink message on the disabled RO, and does not transmit a second uplink message on the disabled RO.

[0105] In some possible embodiments, the time domain unit is a symbol, a half slot or a slot.

[0113] In some possible embodiments, the invalid resource mode is determined by the network device based on an invalid RO, where the network device determines a first RO resource in an RO resource set to be used when a first user equipment transmits a second uplink message, and determines a second RO resource in a subsequent period in the RO resource set to be an invalid RO, where an SSB index mapped by the second RO resource is the same as an SSB index mapped by the first RO resource.

[0114] In one example, the RO set used when transmitting the PRACH of msg.A includes several time domain periods, and the eight occasions for transmitting the PRACH included in one period include RO#0, RO#1, RO#2...RO#7. Here, RO#0 and RO#4 in each period are both mapped to SSB#0. When the UE transmits the PRACH of msg.A based on RO#0 in a certain period, the network device determines RO#0 and RO#4, which have the same SSB index (SSB#0) as RO#0 selected by the UE to initiate the RACH, as invalid ROs in the subsequent periods of this RO set.
