Description

Technical Field

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

[0002] In wireless communication technology, such as the fifth generation mobile communication technology (5G), when performing random access, a user equipment (UE) may use a four-step random access channel (RACH) process or a two-step RACH process.

[0003] In some implementations, the four-step RACH process includes:

[0004] The UE sends a message 1 to the base station. The UE may use a preamble to send the message 1. The preamble may be called a RACH preamble, a physical random access channel (PRACH) preamble, or a sequence.

[0005] The UE receives message 2 from the base station;

[0006] The UE sends a message 3 to the base station, where the message 3 may be message 3 of a Radio Resource Control (RRC) connection request message, in response to receiving the message 2 from the base station;

[0007] The UE receives Message 4 from the base station. If the base station successfully receives and / or decodes Message 3, Message 4 may be a contention resolution message from the base station.

[0008] The UE uses the above four-step RACH process to synchronize with the base station.

[0009] The two-step RACH procedure can combine multiple RACH messages from the four-step RACH procedure. For example, the two-step RACH procedure can include msg.A and msg.B, where msg.A combines msg.1 and msg.3 of the four-step RACH procedure, and msg.B combines msg.2 and msg.4 of the four-step RACH procedure.

[0010] Among them, multiple blind retransmissions can be used for msg.3 to increase redundant bit information, reduce the code rate, and improve transmission reliability.

[0011] In order to ensure that the actual number of blind retransmissions is as consistent as possible with the number of retransmissions indicated by the base station and increase the probability of successful transmission, some implementations support counting blind retransmissions based on available time slots rather than counting based on continuous physical time slots.

[0012] The blind retransmission of msg.3 may conflict with the PRACH sent by other terminals or the PUSCH channel of msg.A sent by other terminals, thereby causing mutual interference between different channel transmissions of different terminals, and ultimately causing random access failure of both. Summary of the Invention

[0014] In a first aspect, a resource conflict handling method is provided. The method is executed by a first user equipment, comprising: determining at least one time domain unit corresponding to overlapping resources between resources used for retransmitting a first uplink message and resources of a physical bearer channel for a second uplink message; wherein the first uplink message is msg.3 and the second uplink message is msg.1 or msg.A;

[0105] The embodiment of the present disclosure provides a resource conflict handling method, which is executed by a first user equipment. Figure 2 FIG. 1 is a flow chart showing a method for handling resource conflicts according to an exemplary embodiment. Figure 2 As shown, the method includes:

[0106] Step S201, determine at least one time domain unit corresponding to the overlapping resources between the resources used to retransmit the first uplink message and the resources of the physical bearer channel of the second uplink message; wherein the first uplink message is message 3 (msg.3), and the second uplink message is message 1 (msg.1) or message A (msg.A).

[0107] Step S202: The first uplink message and the second uplink message are not sent simultaneously with the second user equipment in the at least one time domain unit.

[0108] In some possible implementations, the time domain unit is a symbol, a half slot, or a slot.

[0109] In some possible implementations, the physical bearer channel of the second uplink message includes at least one of the following:

[0110] Physical Random Access Channel (PRACH),

[0111] Physical Uplink Shared Channel (PUSCH).

[0112] In some possible implementations, the second user equipment is any user equipment other than the first user equipment in the cell where the first user equipment is located.

[0113] In some possible implementations, the second user equipment is a user equipment other than the first user equipment that meets the set conditions and is located in the cell where the first user equipment is located.

[0114] In some possible implementations, the resources used for retransmitting the first uplink message and the resources of the physical bearer channel of the second uplink message completely overlap.

[0115] In some possible implementations, resources used for retransmitting the first uplink message and resources of the physical bearer channel of the second uplink message partially overlap.

[0116] In some possible implementations, at least one time domain unit is a continuous time domain unit.

[0117] In some possible implementations, at least one time domain unit is a discontinuous time domain unit.

[0118] In some possible implementations, the first uplink message is a first uplink random access message, and the second uplink message is a second uplink random access message.

[0119] In an embodiment of the present disclosure, a time domain area corresponding to overlapping resources between resources for retransmitting a first uplink message and resources of a physical bearer channel for a second uplink message is determined, and the current user and other user devices do not send the first uplink message and the second uplink message at the same time in this time domain area, thereby preventing resource conflicts between different uplink messages, reducing channel transmission interference between different user devices, and improving the success rate of random access of user devices.

[0120] The embodiment of the present disclosure provides a resource conflict handling method, which is executed by a first user equipment. Figure 3 FIG. 1 is a flow chart showing a method for handling resource conflicts according to an exemplary embodiment. Figure 3 As shown, the method includes:

[0121] Step S301, determine at least one time domain unit corresponding to the overlapping resources between the resources used to retransmit the first uplink message and the resources of the physical bearer channel of the second uplink message; wherein the first uplink message is message 3 (msg.3), and the second uplink message is message 1 (msg.1) or message A (msg.A).

[0122] Step S302: determining that the available time domain units do not include the at least one time domain unit; determining resources for retransmitting the first uplink message based on the available time domain units, or calculating the number of retransmissions based on the available time domain units;

[0123] Step S303: Do not send the first uplink message in the at least one time domain unit.

[0124] In some possible implementations, the time domain unit is a symbol, a half slot, or a slot.

[0125] In some possible implementations, the physical bearer channel of the second uplink message includes at least one of the following: PRACH and PUSCH.

[0126] In some possible implementations, the resources used for retransmitting the first uplink message and the resources of the physical bearer channel of the second uplink message completely overlap.

[0127] In some possible implementations, resources used for retransmitting the first uplink message and resources of the physical bearer channel of the second uplink message partially overlap.

[0128] In some possible implementations, at least one time domain unit is a continuous time domain unit.

[0129] In some possible implementations, at least one time domain unit is a discontinuous time domain unit.

[0130] In some possible implementations, the first uplink message is a first uplink random access message, and the second uplink message is a second uplink random access message.

[0131] In some possible implementations, determining in step S301 at least one time domain unit corresponding to overlapping resources between resources for retransmitting the first uplink message and resources of a physical bearer channel for the second uplink message includes:

[0132] S301-1: Determine a first resource in a resource set used to send a second uplink message.

[0133] S301-2, determine the second resource in the resource set, wherein the SSB index mapped to the second resource is the same as the SSB index mapped to the first resource.

[0134] S301-3: Determine at least one time domain unit corresponding to overlapping resources between the second resource and the resource used for retransmitting the first uplink message.

[0135] In one example, if Figure 4As shown, the resource set used for sending PRACH includes several time domain periods, and one period contains 8 opportunities for initiating PRACH, including RO#0, RO#1, RO#2...RO#7. Among them, RO#0 and RO#4 in each period are mapped to SSB#0. Based on RO#0 of a certain period, the UE sends PRACH. Then, in the subsequent periods of this resource set, the resources occupied by the RO with the same SSB index (SSB#0) as the RO#0 selected by the UE to initiate RACH, and the resources overlapping with the blind retransmission resources of msg.3 are determined as at least one time domain unit.

[0136] In some possible implementations, step S301 - 1 further includes step S301 - 0 , receiving configuration information sent by a network device, where the configuration information indicates a resource set used for sending the second uplink message.

[0137] In some possible implementations, at least one time domain unit is determined to be an unavailable time domain unit for retransmitting the first uplink message, and when the first user equipment determines the resources for retransmitting the first uplink message and calculates the number of retransmissions, the unavailable time domain unit for retransmitting the first uplink message is not taken into account.

[0138] For example: when the time domain unit is a time slot and the first uplink message is msg.3, at least one time slot corresponding to the overlapping resources is determined to be an unavailable time slot for retransmitting the first uplink message (unavailable slots for msg.3 repetitions). When the first user equipment determines the resources for retransmitting msg.3 and calculates the number of retransmissions, the unavailable slots for msg.3 repetitions are not taken into account.

[0139] For example: when 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 overlapping resources is an unavailable symbol for retransmitting the first uplink message (unavailable symbols for msg.3 repetitions). When the first user equipment determines the resources for retransmitting msg.3 and calculates the number of retransmissions, the unavailable symbols for msg.3 repetitions are not taken into account.

[0140] In the embodiment of the present disclosure, the transmission of the second uplink message is given a higher priority, while the transmission of the first uplink message is given a lower priority, and the time domain area corresponding to the overlapping resources is determined to be unavailable for retransmitting the first uplink message. When determining the resources for retransmitting the first uplink message and calculating the number of retransmissions, the above-mentioned unavailable time domain area is not considered, and the first uplink message is not sent on the at least one time domain unit, thereby ensuring the accuracy of parameter determination and the priority of other user devices except the first user device to smoothly send the second uplink message, further preventing resource conflicts between different uplink messages, reducing channel transmission interference of different user devices, and improving the success rate of random access of user devices.

[0141] The embodiment of the present disclosure provides a resource conflict handling method, which is executed by a first user equipment. Figure 5 FIG. 1 is a flow chart showing a method for handling resource conflicts according to an exemplary embodiment. Figure 5 As shown, the method includes:

[0142] Step S501, determine at least one time domain unit corresponding to the overlapping resources between the resources used to retransmit the first uplink message and the resources of the physical bearer channel of the second uplink message; wherein the first uplink message is message 3 (msg.3), and the second uplink message is message 1 (msg.1) or message A (msg.A).

[0143] Step S502: Determine that the available time domain units include the at least one time domain unit; determine resources for retransmitting the first uplink random input message based on the available time domain units, or calculate the number of retransmissions based on the available time domain units.

[0144] Step S503: Do not send the first uplink message in the at least one time domain unit.

[0145] In some possible implementations, the time domain unit is a symbol, a half slot, or a slot.

[0146] In some possible implementations, the physical bearer channel of the second uplink message includes at least one of the following: PRACH and PUSCH.

[0147] In some possible implementations, the resources used for retransmitting the first uplink message and the resources of the physical bearer channel of the second uplink message completely overlap.

[0148] In some possible implementations, resources used for retransmitting the first uplink message and resources of the physical bearer channel of the second uplink message partially overlap.

[0149] In some possible implementations, at least one time domain unit is a continuous time domain unit.

[0150] In some possible implementations, at least one time domain unit is a discontinuous time domain unit.

[0151] In some possible implementations, the first uplink message is a first uplink random access message, and the second uplink message is a second uplink random access message.

[0152] In some possible embodiments, at least one time domain unit is determined to be an available time domain unit for retransmitting the first uplink message, and when the first user equipment determines the resources for retransmitting the first uplink message and calculates the number of retransmissions, the at least one time domain unit is taken into account, but the first uplink message is not sent on the at least one time domain unit.

[0153] For example: when the time domain unit is a time slot and the first uplink message is msg.3, at least one time slot corresponding to the overlapping resources is determined to be an available time slot for retransmitting the first uplink message (available slots for msg.3 repetitions). When the first user equipment determines the resources for retransmitting msg.3 and calculates the number of retransmissions, the available slots for msg.3 repetitions are included, but msg.3 is not sent on the at least one time domain unit.

[0154] For example: when 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 overlapping resources is an available symbol for retransmitting the first uplink message (unavailable symbols for msg.3 repetitions). When the first user equipment determines the resources for retransmitting msg.3 and calculates the number of retransmissions, the unavailable symbols for msg.3 repetitions are taken into account, but msg.3 is not sent on the at least one time domain unit.

[0155] In the embodiment of the present disclosure, the transmission of the second uplink message is given a higher priority, while the transmission of the first uplink message is given a lower priority, and the time domain area corresponding to the overlapping resources is determined as the availability for retransmitting the first uplink message. When determining the resources for retransmitting the first uplink message and calculating the number of retransmissions, the above-mentioned unavailable time domain area is still considered, but the first uplink message is not sent on the at least one time domain unit, thereby ensuring compatibility with existing protocols and the priority of other user devices other than the first user device to smoothly send the second uplink message, further preventing resource conflicts between different uplink messages, reducing channel transmission interference of different user devices, and improving the success rate of random access of user devices.

[0156] The embodiment of the present disclosure provides a resource conflict handling method, which is executed by a first user equipment. Figure 6 FIG. 1 is a flow chart showing a method for handling resource conflicts according to an exemplary embodiment. Figure 6 As shown, the method includes:

[0158] Step S602, determining an invalid random access opportunity RO in the resources of the physical bearer channel, wherein the at least one time domain unit includes the invalid RO;

[0159] Step S603: In response to the second user equipment not sending the second uplink message in the invalid RO, the first user equipment sends the first uplink message in the invalid RO.

[0160] In some possible implementations, in step S603, the first user equipment sends the first uplink message to the invalid RO, and does not send the second uplink message to the invalid RO.

[0161] In some possible implementations, the time domain unit is a symbol, a half slot, or a slot.

[0162] In some possible implementations, the physical bearer channel of the second uplink message includes at least one of the following: PRACH and PUSCH.

[0165] In some possible implementations, at least one time domain unit is a continuous time domain unit.

[0167] In some possible implementations, determining the invalid random access opportunity RO in the resources of the physical bearer channel in step S602 includes: receiving an invalid resource pattern from a network device; wherein the invalid resource pattern indicates an invalid RO.

[0168] In some possible implementations, the invalid resource mode is determined by the network device based on an invalid RO, wherein the network device determines a first RO resource in an RO resource set used by a first user device to send a second uplink message; and determines that a second RO resource in the RO resource set is an invalid RO, wherein the SSB index mapped to the second RO resource is the same as the SSB index mapped to the first RO resource.

[0169] In some possible implementations, the invalid resource mode is determined by the network device based on an invalid RO, wherein the network device determines a first RO resource in an RO resource set used by a first user device to send a second uplink message; and determines that a second RO resource in a subsequent period in the RO resource set is an invalid RO, wherein the SSB index mapped to the second RO resource is the same as the SSB index mapped to the first RO resource.

[0170] In one example, the RO set used to send the PRACH for msg.A includes several time domain periods. One period contains eight opportunities for initiating PRACH, including RO#0, RO#1, RO#2, ... RO#7. RO#0 and RO#4 in each period are mapped to SSB#0. Based on RO#0 of a certain period, if the UE sends the PRACH for msg.A, the network device will determine that RO#0 and RO#4 with the same SSB index (SSB#0) as RO#0 selected by the UE for initiating RACH in subsequent periods of this RO set are invalid ROs.

[0171] An embodiment of the present disclosure provides a method for determining an invalid RO, which is executed by a user equipment and includes:

[0172] An invalid resource pattern is received from a network device, wherein the invalid resource pattern indicates an invalid RO. The invalid resource pattern is determined by the network device based on an invalid RO, wherein the network device determines a first RO resource in a set of RO resources used by a first user equipment to send a second uplink message, and determines that a second RO resource in the set of RO resources is an invalid RO, wherein an SSB index mapped to the second RO resource is the same as an SSB index mapped to the first RO resource.

[0173] In one example, the RO set used to send the PRACH for msg.A includes several time domain periods. Each period contains eight opportunities for initiating PRACH, including RO#0, RO#1, RO#2, ... RO#7. RO#0 and RO#4 in each period are mapped to SSB#0. Based on RO#0 of a certain period, if the UE sends the PRACH for msg.A, the network device determines that RO#0 and RO#4 in this RO set, which have the same SSB index (SSB#0) as RO#0 selected by the UE to initiate RACH, are invalid ROs.

[0176] In one example, the RO set used to send the PRACH for msg.A includes several time domain periods. One period contains eight opportunities for initiating PRACH, including RO#0, RO#1, RO#2, ...
