Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and in particular, to a transmission processing method and apparatus. Background Art

[0002] With the development of technologies, satellite communication has become the focus of future communication. In satellite communication, satellite beams need to point to users to provide network communication services. For service beams for transmitting data, if the coverage area of the satellite is large, since the coverage range of each beam is limited, each service beam can serve multiple wave positions in a time-sharing manner to implement a time-division multiplexing communication mode.

[0003] However, due to the long distance between the satellite and the terminal user and the long propagation delay, the interval time between the downlink DL and the corresponding uplink UL transmission itself is relatively long. According to the existing design of uplink scheduling and feedback timing, it cannot be guaranteed that after the DL is sent, the corresponding UL transmission time is still within the time period when the service beam serves this wave position, which affects the transmission quality. Summary of the Invention

[0129] In the embodiments of the present invention, the term "and / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after.

[0130] In the embodiments of the present application, the term "a plurality of" means two or more, and other quantifiers are similar thereto.

[0131] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0132] It should be noted that flexible timing relationships are supported in 5G New Radio (NR). For the Physical Uplink Control Channel (PUCCH), the corresponding Physical Downlink Control Channel (PDCCH) indicates the scheduling timing relationship (HARQ timing, i.e., K1) between the scheduled Physical Downlink Shared Channel (PDSCH) and the PUCCH. For the Physical Uplink Shared Channel (PUSCH), the PDCCH carrying its scheduling information indicates the scheduling timing relationship (Scheduling timing, i.e., K2) between the PUSCH and the PDCCH. Specifically, the PDCCH uses the PDSCH to Hybrid Automatic Repeat request-ACKnowledgement (HARQ-ACK) feedback timing indication field in the Downlink Control Information (DCI) to indicate the number of time slots K1 between the end of the PDSCH and the start of the HARQ-ACK, that is, the PDSCH transmission ending in time slot n performs HARQ-ACK transmission in time slot n+K1. The full set of K1 is {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15}, and usually up to 8 values are configured for the terminal. The value of K1 is in units of time slots, that is, K1 = 1 means an interval of 1 time slot. K1 = 0 corresponds to the last PUCCH time slot overlapping with the received PDSCH or the PDCCH indicating the SPS PDSCH release.

[0133] The Time Domain Resource Allocation (TDRA) indication field in the DCI indicates the time slot offset K2 between the time slot where the PUSCH is located and the time slot where the DCI is located, that is, the DCI in time slot n indicates that the PUSCH transmission is performed in time slot n+K2. The full set of K2 is {0, 1, 2, 3, 4, ……, 32}, and usually up to 16 values are configured for the terminal through the TDRA table. The value of K2 is in units of time slots, that is, K2 = 1 means an interval of 1 time slot. K2 = 0 corresponds to the first PUSCH time slot overlapping with the time slot where the received PDCCH is located.

[0134] Embodiments of the present invention provide a transmission processing method and apparatus. Among them, the method and the apparatus are based on the same application concept. Since the principles for solving problems by the method and the apparatus are similar, the implementation of the apparatus and the method can be referred to each other, and the repeated parts will not be elaborated.

[0135] As shown Figure 1 in the figure, a transmission processing method provided by an embodiment of the present invention includes:

[0136] Step 101, a terminal receives first configuration information and / or second configuration information, where the first configuration information is used to configure a scheduling timing relationship K1 between a scheduled physical downlink shared channel PDSCH and a physical uplink control channel PUCCH, and the second configuration information is used to configure a scheduling timing relationship K2 between a physical downlink control channel PDCCH carrying scheduling information and a physical uplink shared channel PUSCH;

[0137] Step 102, the terminal determines a position of a corresponding uplink transmission according to the first configuration information and / or the second configuration information;

[0138] wherein, the first configuration information includes a plurality of K1s, and

[0139] the time unit of each K1 is a time slot, and the number of configured K1s is greater than a first value; or, the time unit of each K1 is one or more of a preset time unit;

[0140] the second configuration information includes a plurality of K2s, and

[0141] the time unit of each K2 is a time slot, and the number of configured K2s is greater than a second value; or, the time unit of each K2 is one or more of a preset time unit.

[0142] Here, the first value is a preset threshold of the number of K1s, such as 8; the second value is a preset threshold of the number of K2s, such as 16. That is, on the one hand, when the time unit of a plurality of configured K1s and / or K2s is a time slot, the number increases, expanding the range of optional values. On the other hand, for a plurality of configured K1s and / or K2s, the time unit of each K1 and / or K2 is one or more of a preset time unit, which also expands the range of optional values, and the time range of the optional values is more flexible. In this way, it is possible to better achieve that the determined uplink transmission position covers the corresponding service beam scanning period, ensuring the transmission quality.

[0143] Optionally, the preset time unit includes at least one of the following:

[0144] Millisecond;

[0145] Beam period;

[0146] Time slot.

[0147] That is, one time unit can be any combination of the following: millisecond, beam period, time slot. Among them, one time unit is not limited to one or more of 1 millisecond, 1 beam period, and 1 time slot.

[0148] Taking the first configuration information as an example, if the first configuration information includes multiple K1s, namely: K11, K12, and K13, then K11, K12, and K13 can be the same or different time units, and each can be one or more of the preset time units. For example, K11 is 5 ms + 1 sl, K12 is 1 beam cycle, and K13 is 1 beam cycle + 2 sl. Here, sl represents the time slot unit (slot).

[0149] Of course, when the first configuration information includes multiple K1s that are all the same preset time unit and this time unit is a time slot, the number of K1s among the multiple K1s is greater than the first value; similarly, when the second configuration information includes multiple K2s that are all the same preset time unit and this time unit is a time slot, the number of K2s among the multiple K2s is greater than the second value.

[0150] Optionally, when the time unit of each K1 is one or more of the preset time units, the multiple K1s belong to the same set; or, each K1 belongs to a different set, and the time units of K1s in different sets are different.

[0151] That is to say, for the first configuration information including multiple K1s, when the time unit of each K1 is one or more of the preset time units, the multiple K1s can belong to the same set, or it can be understood that the first configuration information configures a K1 set. The time unit corresponding to the K1 set can be any combination of the following: X1 milliseconds, where X1 is an integer greater than or equal to 1; Y1 beam cycles, where Y1 is an integer greater than or equal to 1; Z1 time slots, where Z1 is an integer greater than or equal to 1.

[0152] Or, the multiple K1s correspond to different K1 sets, different K1 sets correspond to different time units, and each K1 is determined by multiple K1 sets, or it can be understood that the first configuration information configures multiple K1 sets. The time unit corresponding to each K1 set can be any one of the following: X2 milliseconds, where X2 is an integer greater than or equal to 0; Y2 beam cycles, where Y2 is an integer greater than or equal to 0; Z2 time slots, where Z2 is an integer greater than or equal to 0. Here, the values in each K1 set are only part of the K1s, and the value of K1 needs to be determined by multiple K1 sets. For example, if M K1 sets are configured to correspond to different time units respectively, then the value of a K1 is equal to K1_1 + K1_2 + …… + K1_M, where K1_1, K1_2, ……, K1_M are the values of the partial K1s corresponding to the K1 sets with different time units.

[0153] In this embodiment, the configuration of K2 takes into account the implementation of the TDRA table. Optionally, when the time unit of each K2 is one or more of the preset time units, the multiple K2s belong to the same set.

[0154] That is, the second configuration information includes multiple K2s. When the time unit of each K2 is one or more of the preset time units, the multiple K2s can belong to the same set, or it can be understood that the second configuration information configures a set of K2s. The time unit corresponding to this set of K2s can be any combination of the following: X3 milliseconds, where X3 is an integer greater than or equal to 1; Y3 beam periods, where Y3 is an integer greater than or equal to 1; Z3 time slots, where Z3 is an integer greater than or equal to 1.

[0155] It should be noted that after the configuration is completed, on the one hand, the terminal can determine the currently applicable K1 and / or K2 based on the configuration; on the other hand, after the configuration, the network-side device can also indicate the currently applicable K1 and / or K2 through DCI. Thus, corresponding to the indication of the network-side device, optionally, before step 201, it further includes:

[0156] The terminal receives downlink control information DCI, and the DCI includes the first indication information of K1 or the second indication information of K2.

[0157] In this way, the terminal can determine the currently applicable K1 or K2 by receiving the DCI. Among them, the first indication information is the K1 indication field information in the DCI scheduling the PDSCH, and the second indication information is the TDRA indication field information in the DCI scheduling the PUSCH.

[0158] Optionally, when the time unit of each K1 included in the first configuration information is a time slot, the size of the first indication information is determined by the number of configured K1s;

[0159] When the time unit of each K1 included in the first configuration information is one or more of the preset time units, if the multiple K1s belong to the same set, the size of the first indication information is determined by the number of configured K1s; if each K1 belongs to a different set, it is jointly determined by the number of configured K1s and the number of sets.

[0160] Among them, if the first configuration information configures that the time unit of each K1 is a time slot and the number P of configured K1s is greater than the first value, the size of the first indication information can be ceil(log2(P)). For example, if 16 K1s are configured and the time unit of each K1 is a time slot, the size (i.e., the number of bits) of the first indication information is 4 bits.

[0161] If the first configuration information configures the time unit of each K1 as one or more of the preset time units, and all the configured K1s (Q K1s) belong to the same set, the size of the first indication information can be ceil(log2(Q)). For example, if 1 K1 set is configured to include 16 K1s, and the time unit of each K1 in this K1 set is one or more of the preset time units, the size (i.e., the number of bits) of the first indication information is 4 bits.

[0162] If the first configuration information configures the time unit of each K1 as one or more of the preset time units, and each configured K1 belongs to a different set (M K1 sets), the time units of K1s in different sets are different, and the number of K1 values in each K1 set is I 1 ,I 2 ,……,I M , then the size of the first indication information can be ceil(log2(I 1 ) + log2(I 2 ) + …… + log2(I M ). For example, if 2 K1 sets are configured, the first K1 set corresponds to the time slot as the preset time unit, and the first K1 set includes 2 values, the second K1 set corresponds to the millisecond as the preset time unit, and the second K1 set includes 4 values, then the size (i.e., the number of bits) of the first indication information can be 3 (i.e., 1 + 2) bits, that is, 1 bit indicates the value corresponding to the first K1 set, and 2 bits indicate the value corresponding to the second K1 set.

[0163] In this embodiment, optionally, step 102 includes:

[0164] When the DCI includes the first indication information, the terminal determines the target K1 according to the first indication information and the first configuration information;

[0165] The terminal determines the position of the PUCCH according to the target K1, the first offset value, and the position of the PDSCH.

[0166] For the received DCI including the first indication information, first combine the first indication information and the first configuration information to determine the target K1, and then determine the corresponding PUCCH position from the target K1, the first offset value, and the position of the PDSCH. Here, the first offset value K-offset is a pre-configured compensation value, such as a fixed offset length configured by the base station to the terminal through high-layer signaling. For the feedback timing in satellite communication, K-offset is also denoted as TA-offset.

[0167] Of course, if the first offset value is not considered (i.e., the first offset value is 0), after determining the target K1, the position of the corresponding PUCCH can be directly determined from the target K1 and the position of the PDSCH.

[0168] Next, the application of the embodiments of the present application will be described in conjunction with specific scenarios:

[0169] As Figure 2 shown, the transmitted subcarrier spacing is 120 kHz, and there are 8 time slots in 1 ms. The period of beam polling (also known as the beam sweep period) is 20 ms. In every 20 ms, the first 10 ms is allocated to the wave position where User 1 is located, and the latter 10 ms is allocated to the wave position where User 2 is located. Then, for User 1, it is necessary to indicate the uplink transmission in the range of 0-10 ms and 20 ms-30 ms in the figure. To ensure that the base station can flexibly indicate the corresponding time range,

[0170] Method 1: For the PDSCH transmitted in time slot n, the HARQ-ACK feedback time slot is determined based on n+K1. The optional range of K1 is 40-239. The base station configures 120 values of K1 for the terminal, and the corresponding values are {40, 41,..., 79, 160, 161,..., 239}. The size of the first indication information (the number of bits in the K1 indication field information) in the DCI is 7 bits;

[0171] Method 2: For the PDSCH transmitted in time slot n, the HARQ-ACK feedback time slot is determined based on time slot n+K-offset+K1. The value of K-offset is 40, and the optional range of K1 is 0-199. The base station configures 120 values of K1 for the terminal, and the corresponding values are {0, 1,..., 39, 120, 121,..., 199}. The size of the first indication information (the number of bits in the K1 indication field information) in the DCI is 7 bits.

[0172] Method 3: For the PDSCH transmitted in time slot n, the HARQ-ACK feedback time slot is determined based on n+K1. The base station configures the K1 set for the terminal as {5 ms, 6 ms, 7 ms, 20 ms}. The size of the first indication information (the number of bits in the K1 indication field information) in the DCI is 2 bits;

[0173] Method 4: For the PDSCH transmitted in time slot n, the HARQ-ACK feedback time slot is determined based on time slot n+K-offset+K1. The value of K-offset is 40 time slots. The base station configures the K1 set for the terminal as {0 ms, 5 ms, 5 ms+1 sl, 5 ms+2 sl}. The corresponding number of bits in the K1 indication field information in the DCI is 2 bits;

[0174] Method 5: For the PDSCH transmitted in time slot n, the HARQ-ACK feedback time slot is determined based on n+K1. The base station configures the set of K1 for the terminal as {5 ms, 5 ms + 1 sl, 5 ms + 2 sl, 5 ms + 3 sl, 20 ms, 20 ms + 1 sl, 20 ms + 2 sl, 20 ms + 3 sl}, where sl represents the time slot unit. The size of the first indication information in the DCI (the number of information bits in the K1 indication field) is 3 bits.

[0175] Method 6: For the PDSCH transmitted in time slot n, the HARQ-ACK feedback time slot is determined based on n+K1. The base station configures the set of K1 for the terminal as {1 beam cycle, 2 beam cycles}. The size of the first indication information in the DCI (the number of information bits in the K1 indication field) is 1 bit.

[0176] Method 7: The base station configures two sets of K1 for the terminal. For the PDSCH transmitted in time slot n, the HARQ-ACK feedback time slot is determined based on n+K-offset+K1_1+K1_2. The value of K-offset is 80 time slots. The first configured set of K1 is {5 ms, 6 ms, 7 ms, 8 ms, 20 ms, 21 ms, 22 ms, 23 ms}, and the second set of K1 is {0 sl, 1 sl, 2 sl, 3 sl}. The size of the first indication information in the DCI (the number of information bits in the K1 indication field) is 5 bits, where the first three bits are used to indicate the value in the first set of K1, and the last two bits are used to indicate the value in the second set of K1.

[0177] Method 8: For the PDSCH transmitted in time slot n, the HARQ-ACK feedback time slot is determined based on time slot n+K1_1+K1_2. The base station configures the first set of K1 for the terminal as {10 ms, 11 ms, 12 ms, 13 ms}, and the second set of K1 as {0 sl, 1 sl, 2 sl, 3 sl}. The size of the first indication information in the DCI (the number of information bits in the K1 indication field) is 4 bits, where the first two bits are used to indicate the value in the first set of K1, and the last two bits are used to indicate the value in the second set of K1.

[0178] For the above Method 1 and Method 2, it corresponds to the case where the time unit of each K1 configured by the first configuration information is a time slot and the number of configured K1 is greater than the first value; for Method 3 - Method 6, it corresponds to the case where the time unit of each K1 configured by the first configuration information is one or more of the preset time units and all the configured K1 belong to the same set; for Method 7 and Method 8, it corresponds to the case where the time unit of each K1 configured by the first configuration information is one or more of the preset time units, and each configured K1 belongs to a different set, and the time units of K1 in different sets are different.

[0179] In this embodiment, for K2, it is configured in each row of the TDRA. Therefore, specifically, the configuration of K2 is implemented as the base station expanding the number of K2 when configuring the TDRA table for K2 with a time unit of a time slot; alternatively, the same or different preset time units can be configured for the K2 values in each row. For example, the K2 value in the first row of the TDRA table is configured as 5 ms, the K2 value in the second row is 6 ms, the K2 value in the third row is 20 ms, and the K2 value in the fourth row is 20 ms + 1 sl, etc. The specific parameters are configured by the base station. If the second indication information in the DCI indicates K2, the indication method of the TDRA is adopted and will not be elaborated here.

[0180] Optionally, step 102 includes:

[0181] When the DCI includes the second indication information, the terminal determines the target K2 according to the second indication information and the second configuration information;

[0182] The terminal determines the position of the PUSCH according to the target K2, the second offset value, and the position of the PDCCH.

[0183] For the received DCI including the second indication information, the target K2 will be determined by combining the second indication information and the second configuration information first, and then the position of the corresponding PUSCH will be determined by the target K2, the second offset value, and the position of the PDCCH. Here, the second offset value K-offset is a pre-configured compensation value, such as a fixed offset length configured by the base station to the terminal through high-layer signaling. For the feedback timing in satellite communication, K-offset is also denoted as TA-offset.

[0184] Of course, if the second offset value is not considered (i.e., the second offset value is 0), after determining the target K2, the position of the corresponding PUSCH can be directly determined by the target K2 and the position of the PDCCH.

[0185] For example, for the PDCCH transmitted in time slot n, the time slot for PUSCH transmission is n + K-offset + K2, or the time slot for PUSCH transmission is determined based on n + K2.

[0186] It should be noted that in the embodiments of the present invention, when determining the HARQ-ACK feedback time slot or the PUSCH transmission time slot, the time units of the time slot n, K-offset, K1, and K2 therein may be different, so they need to be converted to the same time unit. For the HARQ-ACK feedback timing, it can be converted to the time slot unit of the PUCCH; for the PUSCH scheduling timing, it can all be converted to the time slot unit of the PUSCH. For example, when determining the HARQ-ACK feedback timing, for the PDSCH whose end position is transmitted in the uplink time slot n, if the time unit of K-offset is milliseconds and the time unit of K1 is time slots, then the HARQ-ACK feedback time slot is n + K-offset * 2 u + K1. For another example, when determining the HARQ-ACK feedback timing, for the PDSCH whose end position is transmitted in the uplink time slot n, if the time unit of K1 is the beam cycle (10 ms), then the HARQ-ACK feedback time slot is n + K1 * 10 * 2 u . In the above examples, u is the parameter number corresponding to the uplink SCS; for example, the u value corresponding to 120 kHz is 3.

[0187] In summary, the method of the embodiments of the present invention can support indicating the effective HARQ-ACK feedback time slot or the PUSCH transmission time slot when the service beam periodically switches among different wave positions in satellite communication, and realizing the transmission timing indication in the time period covering the current wave position within the service beam scanning cycle.

[0188] The network-side device in the embodiments of the present invention may be, but is not limited to: a base station, a central control unit (Central Unit, CU).

[0189] As Figure 3 shown, the embodiments of the present invention further provide a transmission processing method, including:

[0190] Step 301, the network-side device sends the first configuration information and / or the second configuration information;

[0191] wherein, the first configuration information is used to configure the scheduling timing relationship K1 between the scheduled physical downlink shared channel PDSCH and the physical uplink control channel PUCCH, and the second configuration information is used to configure the scheduling timing relationship K2 between the physical downlink control channel PDCCH carrying the scheduling information and the physical uplink shared channel PUSCH;

[0195] the time unit of each K2 is a time slot, and the number of configured K2s is greater than a second value; or the time unit of each K2 is one or more of the preset time units.

[0196] Here, the first value is a threshold number of K1s preset, such as 8; the second value is a threshold number of K2s preset, such as 16. That is, on the one hand, when the time units of the configured plurality of K1s and / or K2s are all time slots, the number increases, expanding the range of optional values. On the other hand, for the configured plurality of K1s and / or K2s, the time unit of each K1 and / or K2 is one or more of the preset time units, which also expands the range of optional values, and the time range of the optional values is more flexible. In this way, it is possible to better achieve that the determined uplink transmission position is covered within the corresponding service beam scanning period, ensuring the transmission quality.
