Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a method, device, terminal and network-side equipment for determining repeated transmission. Background Art

[0002] In current 5G (fifth generation) NR (New RAT) mobile communication systems, cell coverage is a critical technical indicator. However, Msg3 PUSCH (Physical Uplink Shared Channel) transmission is a coverage bottleneck in 5G NR systems. Therefore, enhancing Msg3 PUSCH coverage is a key research topic.

[0003] Currently, a repetition type A retransmission mechanism has been introduced for Msg3 PUSCH transmission. However, there is currently no clear solution for determining the number of Msg3 PUSCH retransmissions. Furthermore, considering that Msg3 PUSCH transmission is in the initial access phase, the terminal at this time can only obtain the cell-common TDD uplink and downlink configuration sent by SIB (System Information Block) 1, and cannot obtain the terminal-specific UE-dedicated uplink and downlink configuration of other terminals. When Msg3 PUSCH is transmitted on multiple slots, there is currently no clear method for determining the available uplink time slots. Summary of the Invention

[0162] In embodiments of the present invention, the term "and / or" describes the association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0163] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0164] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0165] The present application provides a method and apparatus for determining repeated transmissions. The method and apparatus are based on the same application concept. Since the method and apparatus solve similar problems, the implementation of the apparatus and method can refer to each other, and the repetitive parts will not be repeated.

[0166] like Figure 1 FIG. 1 is a flow chart of a method for determining repeated transmission provided in an embodiment of the present invention, which is applied to a terminal. The method includes:

[0167] Step 101: The terminal obtains a random access response RAR, where the RAR includes an uplink grant UL grant and first information other than the UL grant;

[0168] Step 102: The terminal determines the number of repetitions of the initial transmission of Msg3 according to the UL grant and / or the first information;

[0169] Here, the terminal may determine the number of repeated transmissions of the initial transmission of Msg3 according to the UL grant or the first information, or the UL grant and the first information, thereby improving the flexibility of Msg3 resource allocation.

[0170] Step 103: The terminal determines a target time slot for transmitting the Msg3 according to the number of repeated transmissions of the initial transmission of the Msg3 and the available time slot for transmitting the Msg3.

[0171] In this step, the terminal can determine the target time slot for transmitting the Msg3 based on the number of repeated transmissions of the initial Msg3 transmission and the available time slot for transmitting the Msg3, thereby ensuring that the terminal can correctly determine the available uplink time slot when sending the Msg3 subsequently.

[0172] According to the method for determining repeated transmission in an embodiment of the present invention, the terminal obtains a random access response RAR, wherein the RAR includes an uplink authorization UL grant and a first information other than the UL grant; determines the number of repeated transmissions of the initial transmission of Msg3 according to the UL grant and / or the first information; and determines the target time slot for transmitting the Msg3 according to the number of repeated transmissions of the initial transmission of Msg3 and the available time slot for transmitting the Msg3. In this way, the number of repeated transmissions of the initial transmission of Msg3 can be determined based on the UL grant and / or the first information other than the UL grant in the RAR, and then the available uplink time slot for transmitting the Msg3 can be determined, which can improve the flexibility of Msg3 resource allocation while ensuring its transmission performance.

[0173] As an optional implementation, the method of the embodiment of the present invention may further include:

[0174] Receive first indication signaling sent by a network-side device, where the first indication signaling is used to indicate any of the following:

[0175] Used to instruct the terminal to determine the number of repeated transmissions of the initial transmission of Msg3 according to the first information;

[0176] Used to instruct the terminal to determine the number of repeated transmissions of the initial transmission of Msg3 according to the UL grant;

[0177] Used to instruct the terminal to determine the number of repeated transmissions of the initial transmission of Msg3 according to the first information and the UL grant.

[0178] That is, the first indication signaling sent by the network side device instructs the terminal to determine the number of repeated transmissions of the initial transmission of Msg3 according to the first information, the UL grant, or the first information and the UL grant.

[0179] Optionally, the first indication signaling is indication signaling carried by SIB1. Specifically, the first indication signaling is indicated by N bits of information carried by SIB1, where N is an integer greater than or equal to 1.

[0180] It should be noted that there is no limitation on the definition of the first information and the related information fields in the UL grant.

[0181] Assume that there are terminals in the system that require coverage enhancement. To ensure the reliability of their random access process, Msg3 needs to be repeatedly transmitted. Msg3 PUSCH transmission can be divided into two steps: indicating the number of retransmissions and determining the time domain resources.

[0182] In one example, the network side device (such as a base station) instructs the terminal to determine the number of repeated transmissions of the initial transmission of Msg3 according to the information carried by the first information or to determine the number of repeated transmissions of the initial transmission of Msg3 according to the information carried by the UL grant through the indication signaling carried by SIB1.

[0183] Specifically, the indication signaling carried by the SIB1 includes 1-bit indication information indicating a method for determining the number of retransmissions of the initial transmission of Msg3. In this example, the 1-bit indication information has the following functions:

[0184]

[0185] If the indication information carried in SIB1 is in state 0, the network-side device indicates the number of repetitions of the initial Msg3 PUSCH transmission through the information carried in the first information; if the indication information carried in SIB1 is in state 1, the network-side device indicates the number of repetitions of the initial Msg3 PUSCH transmission through the information carried in the UL grant. This example does not impose any restrictions on the definition of the first information and the related information fields in the UL grant.

[0186] It should be noted that since the terminal is in the initial random access phase, it can only obtain the cell-level time division duplex uplink and downlink configuration TDD UL-DL configuration sent by SIB1. However, for other terminals that have entered the connected state, the network side device can configure the terminal-specific UE-dedicated TDD UL-DL configuration for them. The UE-dedicated TDD configuration can configure the semi-static flexible symbol as DL. Here,

[0187] Of course, the network side device (such as the base station) can also instruct the terminal to jointly determine the number of repeated transmissions of the initial transmission of Msg3 according to the information carried by the first information and the information carried by the UL grant through the indication signaling carried by SIB1.

[0188] As an optional implementation, in step 102 of the method of the embodiment of the present invention, the terminal determines the number of repeated transmissions of the initial transmission of Msg3 according to the UL grant and the first information, including:

[0189] The number of repeated transmissions of the initial transmission of Msg3 is determined according to the reserved bits in the first information and the reserved bits in the UL grant.

[0190] Here, the number of repeated transmissions of the initial transmission of Msg3 is determined based on the reserved bits in the first information and the reserved bits in the UL grant.

[0191] As another optional implementation, in step 102 of the method of the embodiment of the present invention, the terminal determines the number of repeated transmissions of the initial transmission of Msg3 according to the UL grant and the first information, including:

[0192] The number of repeated transmissions of the Msg3 initial transmission is determined according to the value range of the timing advance TA value carried in the first information and the indication information carried in the UL grant.

[0193] Here, the number of repeated transmissions of the initial transmission of Msg3 is determined based on the value range of the timing advance TA value carried in the first information, that is, TArange, and the indication information carried in ULgrant.

[0194] Specifically, determining the number of repeated transmissions of the Msg3 initial transmission according to the value range of the timing advance TA value carried in the first information and the indication information carried in the UL grant includes at least one of the following methods:

[0195] Determine, by using a value range of the TA value carried in the first information, a time domain resource allocation table to be used; indicate, by using the TDRA indication field carried in the UL grant, time domain resource allocation information in the time domain resource allocation table; and determine, based on the time domain resource allocation information, a number of repetitions for the initial transmission of Msg3;

[0196] Here, the TAcommand information field carried by the base station in the first information indicates the corresponding TA value, and the terminal receives the TAcommand carried in the first information and determines the corresponding TA value. The base station and the terminal determine the relationship between the value range of the TA value and the time domain resource allocation table TDRAtable through predefined rules. For example, when the TA value is less than or equal to the first threshold value (the first threshold value is determined by a predefined method or a network-side configuration method (such as SIB1)), TDRAtable#1 is used; when the TA value is greater than the first threshold value, TDRAtable#2 is used. Furthermore, the terminal and the base station perform the number of repeated transmissions of the initial transmission of Msg3 based on the corresponding TDRAtable.

[0197] Determine a value range of the number of repeated transmissions of the initial Msg3 transmission by using a value range of the TA value carried in the first information; and indicate the number of repeated transmissions of the initial Msg3 transmission within the value range of the number of repeated transmissions by using the first indication information carried in the UL grant;

[0198] Here, the TA command information field carried by the base station in the first information indicates the corresponding TA value. The terminal receives the TA command carried in the first information and determines the corresponding TA value. The base station and the terminal determine the relationship between the TA value range and the Msg3 PUSCH repetition number value range (i.e., the value range of the number of repeated transmissions of the Msg3 initial transmission) through predefined or SIB1-notified rules. For example, when the TA value is less than or equal to the second threshold value (the second threshold value is determined by a predefined method or a network-side configuration method (such as SIB1)), the Msg3 PUSCH repetition number value range is {a1, a2, a3...}; when the TA value is greater than the second threshold value, the Msg3 PUSCH repetition number value range is {b1, b2, b3...}. Furthermore, the base station and the terminal determine the actual number of repeated transmissions based on the corresponding Msg3 PUSCH repetition number value range and the repeated transmission number indication field carried in the UL grant.

[0199] Determine the scaling factor of the number of repeated transmissions of the initial transmission of Msg3 through the value range of the TA value carried in the first information; and determine the number of repeated transmissions indicated by the UL grant through the second indication information carried in the UL grant; determine the number of repeated transmissions of the initial transmission of Msg3 based on the scaling factor and the number of repeated transmissions indicated by the UL grant.

[0200] Here, the TA command information field carried by the base station in the first information indicates the corresponding TA value, and the terminal receives the TA command carried in the first information and determines the corresponding TA value. The base station and the terminal determine the relationship between the value range of the TA value and the scaling factor of the number of repeated transmissions of the Msg3 initial transmission, Msg3 PUSCH repetitionnumber, through predefined or SIB1-notified rules. For example, when the TA value is less than the third threshold value T, the scaling factor (scaling factor) K=1; when the TA value is greater than or equal to T, the scaling factor K=2. Furthermore, the number of repeated transmissions R indicated by the relevant indication information carried in the UL grant and the scaling factor K are used to determine the number of repeated transmissions of the Msg3 initial transmission to be K*R.

[0201] As an optional implementation, the method of the embodiment of the present invention may further include:

[0202] According to a predefined rule or a network instruction, an available time slot for transmitting the Msg3 is determined.

[0203] Optionally, in this step, determining an available time slot for transmitting the Msg3 according to a predefined rule includes one of the following methods:

[0204] Using only the semi-static uplink timeslot as the available timeslot for transmitting the Msg3;

[0205] Using the semi-static uplink timeslot and the semi-static flexible timeslot as available timeslots for transmitting the Msg3;

[0206] The semi-static flexible time slot does not include a semi-static flexible symbol used to transmit any of the following channels or information:

[0207] Synchronization signal block SSB;

[0208] Control resource set CORSET#0;

[0209] Type 0 public search space CSS.

[0210] Here, after the terminal obtains the number of repeated transmissions of the initial transmission of Msg3 through step 102 of the method of the embodiment of the present invention, it can determine the available time slot for transmitting the Msg3 through one of the above methods.

[0211] It should be noted that, in the case of semi-static uplink time slots and semi-static flexible time slots, which are available time slots for transmitting the Msg3, the base station does not send any UE-dedicated downlink data or signals on all symbols where the Msg3 is transmitted; and the terminal does not expect the base station to send any UE-dedicated downlink data or signals. This can avoid transmission failures caused by some of the terminals that need to repeatedly transmit Msg3 due to downlink conflicts with other terminals, thereby avoiding damage to the transmission performance of the Msg3 PUSCH.

[0212] First, after obtaining the number of repetition transmissions of the initial transmission of Msg3, the terminal uses and only uses the semi-static uplink time slot as the available time slot for transmitting the Msg3. A specific example is provided below to illustrate this.

[0213] like Figure 2As shown, it is assumed that the TDD UL-DL configuration structure notified by SIB1 is DDSUUDDSUU. Additionally, SIB1 indicates the number of repeated transmissions of the initial transmission of Msg3 indicated by the first information or UL grant through the Msg3 PUSCH repetition indication mode information field. In this example, it is assumed that the base station indicates the number of repeated transmissions of the initial transmission of Msg3 through the relevant information in the UL grant, and it is assumed that the number of repeated transmissions is 4. Since the available time slots for transmitting the Msg3 are only semi-static uplink time slots, based on the number of repeated transmissions and the semi-static uplink time slots (the block diagram portion indicated by the slash in the figure), the target time slot for transmitting Msg3 is determined, which is the time slot represented by the 4 block diagram portions indicated by the slash in the figure, that is, the semi-static uplink time slots.

[0214] On the other hand, after obtaining the number of repetition transmissions of the initial transmission of Msg3, the terminal uses the semi-static uplink time slot and the semi-static flexible time slot as available time slots for transmitting the Msg3. A specific example is provided below to illustrate this.

[0215] like Figure 3 As shown, it is assumed that the TDD UL-DL configuration structure notified by SIB1 is DDDDSSSSUU. Additionally, SIB1 indicates the number of repetitions of the initial transmission of Msg3 indicated by the first information or UL grant through the Msg3 PUSCH repetition indication mode information field. In this example, it is assumed that the base station indicates the number of repetitions of the initial transmission of Msg3 through the relevant information in the UL grant, and it is assumed that the number of repetitions is 4. Assume that the terminal detects and receives the UL grant on the fourth DL slot, and the time domain resource indication field carried in the UL grant indicates K2=1, that is, Msg3 is transmitted in the first slot after the slot of ULgrant transmission. Assume that the network side sends Type0-CSS on slot#5. The slot that can be used to send Msg3 PUSCH is as follows Figure 3 The time slots represented by the 4 horizontal line parts of the block diagram.

[0216] In this example, Msg3 PUSCH can only be transmitted on semi-static UL and semi-static flexible symbols that are not used to transmit SSB / CORESET#0 / Typ0 CSS. When the terminal encounters a symbol or slot that cannot transmit Msg3 PUSCH, the repeated transmission of the Msg3 PUSCH is delayed.

[0217] For semi-static flexible symbols that do not transmit SSB / CORESET#0 / Typ0 CSS, the terminal does not expect the base station to schedule any downlink transmissions on these symbols. When configuring the UE-dedicated TDD UL DL configuration for the terminal, the base station does not set these symbols as DL and does not schedule downlink transmissions for other terminals. This prevents terminals that need to repeatedly transmit Msg3 from colliding with downlink transmissions from other terminals, leading to transmission failures and minimizing Msg3 PUSCH transmission performance.

[0218] Alternatively, in this step, determining an available time slot for transmitting the Msg3 according to a network instruction includes:

[0219] Receive a second indication signaling sent by a network-side device, where the second indication signaling is used to instruct the terminal to determine an available time slot for transmitting the Msg3 according to one of the following methods:

[0220] Using only the semi-static uplink timeslot as the available timeslot for transmitting the Msg3;

[0221] Using the semi-static uplink timeslot and the semi-static flexible timeslot as available timeslots for transmitting the Msg3;

[0222] The semi-static flexible time slot does not include a semi-static flexible symbol used to transmit any of the following channels or information:

[0223] SSB;

[0224] CORSET#0;

[0225] Type 0 CSS.

[0226] Optionally, if the available time slots for transmitting the Msg3 include the semi-static flexible time slots, the terminal does not expect the network-side device to transmit downlink data or configure downlink symbols on the semi-static flexible symbols occupied by the Msg3.

[0227] Optionally, the terminal may determine a corresponding method for determining an available time slot for transmitting the Msg3 through an indication of relevant information (ie, the second indication signaling) carried by the SIB1 sent by the network side device.

[0228] As an optional implementation, after determining the target time slot for transmitting the Msg3, the method of the embodiment of the present invention may further include:

[0229] Send Msg3 at the determined target time slot.

[0230] According to the method for determining repeated transmission in an embodiment of the present invention, the terminal obtains a random access response RAR, wherein the RAR includes an uplink authorization UL grant and a first information other than the UL grant; determines the number of repeated transmissions of the initial transmission of Msg3 according to the UL grant and / or the first information; and determines the target time slot for transmitting the Msg3 according to the number of repeated transmissions of the initial transmission of Msg3 and the available time slot for transmitting the Msg3. In this way, the number of repeated transmissions of the initial transmission of Msg3 can be determined based on the UL grant and / or the first information other than the UL grant in the RAR, and then the available uplink time slot for transmitting the Msg3 can be determined, which can improve the flexibility of Msg3 resource allocation while ensuring its transmission performance.

[0231] like Figure 4 FIG. 1 is a flow chart of a method for determining repeated transmission provided by an embodiment of the present invention, which is applied to a network-side device and includes:

[0232] Step 401: The network side device indicates the number of repetitions of the initial transmission of Msg3 to the terminal through the uplink grant UL grant in the random access response RAR and / or the first information other than UL grant;

[0233] Here, the network side device can indicate the number of repeated transmissions of the initial transmission of Msg3 to the terminal through the UL grant or the first information, or the UL grant and the first information, so as to improve the flexibility of the resource allocation of Msg3.

[0234] Step 402: The network-side device determines a target time slot for transmitting the Msg3 based on the number of repeated transmissions of the initial transmission of the Msg3 and the available time slot for transmitting the Msg3.

[0235] In this step, the network side device can determine the target time slot for transmitting the Msg3 based on the number of repeated transmissions of the initial transmission of Msg3 and the available time slot for transmitting the Msg3, thereby ensuring that the network side device can receive the Msg3 in the correct uplink time slot.

[0236] According to the method for determining repeated transmission in an embodiment of the present invention, a network-side device indicates the number of repeated transmissions of the initial transmission of Msg3 of the terminal through an uplink grant UL grant in a random access response RAR and / or the first information other than the UL grant; and determines the target time slot for transmitting the Msg3 based on the number of repeated transmissions of the initial transmission of the Msg3 and the available time slot for transmitting the Msg3. In this way, the number of repeated transmissions of the initial transmission of the Msg3 can be determined based on the UL grant and / or the first information other than the UL grant in the RAR, and then the available uplink time slot for transmitting the Msg3 can be determined, thereby improving the flexibility of Msg3 resource allocation while ensuring its transmission performance.

[0237] As an optional implementation, the method of the embodiment of the present invention may further include:

[0238] Sending a first indication signaling to the terminal, where the first indication signaling is used to indicate any one of the following:

[0242] That is, the first indication signaling is sent to the terminal through the network side device, instructing the terminal to determine the number of repeated transmissions of the initial transmission of Msg3 according to the first information, the UL grant, or the first information and the UL grant.

[0243] Optionally, the first indication signaling is indication signaling carried by SIB1. Specifically, the first indication signaling is indicated by N bits of information carried by SIB1, where N is an integer greater than or equal to 1.

[0244] It should be noted that there is no limitation on the definition of the first information and the related information fields in the UL grant.

[0245] As an optional implementation, in step 401, the network-side device indicates the number of repetitions of the initial transmission of Msg3 to the terminal through the uplink grant UL grant and the first information other than the UL grant in the random access response RAR, which may specifically include:

[0248] According to the value range of the timing advance TA value carried in the first information and the indication information carried in the UL grant, the terminal is instructed to transmit the number of repetitions of the initial transmission of Msg3.

[0249] Specifically, according to the value range of the timing advance TA value carried in the first information and the indication information carried in the UL grant, instructing the terminal to repeat the number of initial transmissions of Msg3, including at least one of the following methods:

[0250] Determine, by using a value range of the TA value carried in the first information, a time domain resource allocation table used by the terminal; indicate, by using the TDRA indication field carried in the UL grant, the time domain resource allocation information in the time domain resource allocation table; and indicate, according to the time domain resource allocation information, the number of repetitions of the initial transmission of Msg3 to the terminal;

[0251] Determine, by using the value range of the TA value carried in the first information, a value range of the number of repeated transmissions of the initial Msg3 transmission of the terminal; and indicate, by using the first indication information carried in the UL grant, the number of repeated transmissions of the initial Msg3 transmission within the value range of the number of repeated transmissions;

[0252] Determine the scaling factor of the number of repeated transmissions of the initial transmission of the terminal Msg3 through the value range of the TA value carried in the first information; and determine the number of repeated transmissions indicated by the UL grant through the second indication information carried in the UL grant; determine the number of repeated transmissions of the initial transmission of the terminal Msg3 based on the scaling factor and the number of repeated transmissions indicated by the UL grant.

[0253] As an optional implementation, the method of the embodiment of the present invention may further include:

[0254] According to a predefined rule, an available time slot for transmitting the Msg3 is determined.

[0255] Specifically, determining an available time slot for transmitting the Msg3 according to a predefined rule includes one of the following methods:

[0257] Using the semi-static uplink timeslot and the semi-static flexible timeslot as available timeslots for transmitting the Msg3;

[0262] As an optional implementation, the method of the embodiment of the present invention may further include:

[0263] Sending a second indication signaling to the terminal, where the second indication signaling is used to instruct the terminal to determine an available time slot for transmitting the Msg3 according to one of the following methods:

[0270] Optionally, if the available time slot for transmitting the Msg3 includes the semi-static flexible time slot, the network side device does not transmit downlink data or configure downlink symbols on the semi-static flexible symbols occupied by the Msg3.

[0271] According to the method for determining repeated transmission in an embodiment of the present invention, a network-side device indicates the number of repeated transmissions of the initial transmission of Msg3 of the terminal through an uplink grant UL grant in a random access response RAR and / or the first information other than the UL grant; and determines the target time slot for transmitting the Msg3 based on the number of repeated transmissions of the initial transmission of the Msg3 and the available time slot for transmitting the Msg3.
