Fig. 1 illustrates a flow diagram of some embodiments of a method of transmission of data of the present disclosure.
As shown in fig. 1, in step 110, the number of a plurality of slots for joint transmission of the current TB is determined.
In step 120, the corresponding transmission content of each slot is determined according to the number of the plurality of slots and the related information of the current TB. For example, the related information of the current TB includes size information or RV information of the current TB.
In some embodiments, the current TB is divided into a plurality of sections according to the number of the plurality of slots and the size of the current TB; each time slot is allocated a respective portion as its transmission content. Thus, 1 TBS can be determined by using a plurality of slots jointly, and 1 TB of partial bits is transmitted per slot.
In step 130, the current TB is jointly transmitted using a plurality of slots according to the transmission contents corresponding to each slot.
For example, step 120 and step 130 may be implemented according to the embodiment of fig. 2a by jointly determining 1 TBS with multiple slots, each slot transmitting a part of the bits of the TB.
Fig. 2a shows a schematic diagram of some embodiments of steps 120 and 130 of fig. 1.
As shown in fig. 2a, the current TB with size of N bits is divided into k parts, where k is the number of multiple slots, e.g., k equals 4. The first k-1 parts are respectively allocated to the first k-1 time slots as transmission contents, and the kth part is allocated to the kth time slot as the transmission contents.
In some embodiments, N bits of the current TB are jointly transmitted by k slots.
For example, the first k-1 parts are all N bits in size, and the kth part is N- (k-1) × N in size. That is, the first k-1 slots transmit the same size of content, and the k-th slot transmits the remaining part of the content of the current TB.
For example, the first k-1 slots transmit N/k bits, and the kth slot transmits N- (k-1) x (N/k) bits. I.e. each slot transmits N/k bits of content.
For example, step 120 may be implemented according to the embodiment of fig. 2b by jointly determining 1 TBS using multiple slots, each slot transmitting a different RV version.
Fig. 2b shows a schematic diagram of further embodiments of steps 120 and 130 of fig. 1.
As shown in fig. 2b, different RVs of the current TB may be allocated to different slots as their transmission contents according to the number of the multiple slots and the respective RVs of the current TB.
In some embodiments, the RVs of the current TB, including RV0, RV1, RV2, RV3, are transmitted by slot 1, slot 2, slot 3, slot 4, respectively.
In some embodiments, a technique of transmitting 1 TB in combination with a repetitive transmission technique may be used in conjunction with multiple slots.
For example, different parts of the current TB may be transmitted using a plurality of slots, respectively, and different RVs of the current TB may be transmitted using a duplicate transmission technique, and step 120 may be implemented according to the embodiment of fig. 3 a.
FIG. 3a is a schematic diagram of still other embodiments of steps 120 and 130 of FIG. 1.
As shown in fig. 3a, the plurality of slots includes a plurality of slot sets, each including k slots. For example, the first set of timeslots includes timeslots 1-4 and the second set of timeslots includes timeslots 5-8.
Dividing the current TB with the size of N bits into k parts, wherein the first k-1 parts are all N bits in the same size, and the kth part is N- (k-1) x N in size. The first k-1 parts are respectively allocated to the first k-1 time slots in each time slot set as transmission contents, and the kth part is allocated to the kth time slot in each time slot set as the transmission contents.
Repeatedly transmitting the current TB using a plurality of sets of slots. For example, the first set of slots jointly transmits RV0 for the current TB and the second set of slots jointly transmits RV1 for the current TB.
For example, different RVs of the current TB may be transmitted using a plurality of slots respectively, and all RVs of the current TB may be repeatedly transmitted using a repeat transmission technique, and step 120 may be implemented according to the embodiment of fig. 3 b.
Fig. 3b shows a schematic diagram of further embodiments of steps 120 and 130 of fig. 1.
As shown in fig. 3b, the plurality of slots includes a plurality of slot sets, each including k slots. For example, the first set of timeslots includes timeslots 1-4 and the second set of timeslots includes timeslots 5-8.
The RVs of the current TB are respectively allocated to each time slot in each time slot set as transmission content, so that the current TB is repeatedly transmitted by using a plurality of time slot sets. For example, timeslots 1-4 are respectively transmitted for RV0, RV2, RV3, RV1, and timeslots 5-8 are respectively repeatedly transmitted for RV0, RV2, RV3, RV 1. Thereby, the first time slot set and the second time slot set are enabled to repeatedly transmit each RV.
In some embodiments, the number of the plurality of slots may be determined according to a configuration of RRC. The number of the plurality of slots may also be determined according to a dynamic indication of the DCI. The number of the plurality of timeslots may also be determined based on the number of consecutive uplink timeslots available in the TDD frame structure.
The number of time slots may be determined by the embodiment in fig. 4a, for example.
Fig. 4a shows a schematic diagram of some embodiments of a transmission method of data of the present disclosure.
As shown in fig. 4a, the slot denoted by D is used for downlink, the slot denoted by U is used for uplink, and the slot denoted by S is used for special subframe. The current TB may be jointly transmitted using RRC signaling configuration or DCI dynamic indication of the 3 slots numbered U.
The number of time slots may be determined by the embodiment in fig. 4b, for example.
Fig. 4b shows a schematic diagram of further embodiments of the transmission method of data of the present disclosure.
As shown in fig. 4b, the TBS may be determined by the number of consecutive uplink timeslots available in the TDD frame structure. For example, TB1 may be transmitted using a single slot and TB2 may be jointly transmitted using 2 slots. Therefore, the frame structure can determine which time slots transmit one TB together without special indication of signaling, thereby saving resources and improving efficiency.
