Problems solved by technology

[0005]However, in the current solution, in order to enable the resource of UE's uplink data (PUSCH resource carrying uplink data, also called PUSCH resource) to be multiplexed The short PUCCH resources used, how the UE determines its own actual transmission PUSCH resources, especially the PUCCH resources of different UEs (including long PUCCH resources and / or short PUCCH resources, which are not specifically described below, can be long PUCCH resources and / or or short PUCCH resources) and transmission PUSCH resources appear in the same physical resource block (Physical Resource Block, PRB), how the UE should determine its own actual transmission PUSCH resources, has not found a suitable way to solve it, so It will lead to a lot of wasted resources, high overhead, and low instruction efficiency

example 1

[0387] image 3 Schematic illustration of determining transmission PUSCH resources in a slot in the embodiment of the method for determining data transmission resources for the present disclosure Figure 1 ;Such as image 3 As shown, for the case where there is only short PUCCH in the slot, the base station allocates transmission PUSCH resources, namely PRB, for UE1, UE2, UE3 and UE4 respectively; meanwhile, the base station configures short PUCCH for other UEs in the slot.

[0388] For UE1, the base station can notify the PRB of UE1's PUSCH, and indicate that the OFDM symbol at which UE1's PUSCH ends is the reciprocal (from image 3 In the direction from right to left, the following conditions are the same) the third OFDM symbol (the symbol after the penultimate OFDM symbol sends PUSCH does not send PUSCH); UE1 receives the PRB allocated for transmission of PUSCH sent by the base station, And receiving the indication, UE1 determines that among the PRBs transmitting the PUSC...

[0392] Figure 4 Schematic illustration of determining transmission PUSCH resources in a slot in the embodiment of the method for determining data transmission resources for the present disclosure Figure II ;Such as Figure 4 As shown, relative to Example 1, in Example 2, the base station allocates PRB resources for transmitting PUSCH to UE5 to UE8, and indicates the PUCCH situation in the PRB of the PUSCH.

[0393] For UE5, the base station allocates resources for transmitting PUSCH to UE5, and indicates that there is UE5's own short PUCCH in the transmission PUSCH resource; UE5 also needs the base station to notify itself of the number and location of OFDM symbols of the short PUCCH, here is the last OFDM in the slot Symbol, the PRB or subcarrier occupied by the short PUCCH of UE5 can be indicated or agreed; there will be information about the short PUCCH configuration of UE, and the notification of the above short PUCCH can be realized as UE5; UE5 receives the transmissio...

[0395] Figure 5 Schematic illustration of determining transmission PUSCH resources in a slot in the embodiment of the method for determining data transmission resources for the present disclosure Figure three ;Such as Figure 5 As shown, compared with Example 1, in Example 3, the base station allocates PRB resources for transmitting PUSCH to UE9 to UE11, and indicates the PUCCH situation in the PRB of the PUSCH.

[0396] The base station allocates the PRB for transmitting the PUSCH to UE9, and indicates the countdown (from Figure 5 In the direction from right to left, the following conditions are the same) The second OFDM symbol is not used by PUSCH. The base station will receive the PUSCH data of UE9 in other OFDM symbols except the penultimate OFDM symbol in the PRB; UE9 receives the PRB information sent by the base station for transmitting PUSCH and receives the instruction, and UE9 determines the penultimate OFDM symbol in the PRB The second OFDM symbol will not be u...

Abstract

The embodiment of the disclosure discloses a method for determining data transmission resources. The method includes following steps: transmitting physical uplink shared channel resource information and indication information, wherein the physical uplink shared channel resource information comprises data transmission resources distributed for user equipment in a physical uplink shared channel, andthe indication information is used for indicating whether the data transmission resources include physical uplink control channel resources, and / or the indication information is used for indicating practical data transmission resources in the data transmission resources. The embodiment of the disclosure also discloses an apparatus, a terminal, a base station and equipment for determining data transmission resources.

Description

technical field [0001] The present disclosure relates to the technical field of resource allocation in the communication field, and in particular to a method, device, terminal, base station, and equipment for determining data transmission resources. Background technique [0002] The new generation of mobile communication system (New Radio, NR) is being studied and standardized; in the NR system that can be determined at present, there will be three typical and common service types in the future, including: Enhanced Mobile Broadband (enhanced Mobile BroadBand , eMBB), ultra-reliable and low-latency communications (Ultra-Reliable and LowLatency Communications, URLLC) and massive machine-type communications (massive Machine Type Communications, mMTC); these services have different requirements for latency, coverage, and reliability. For example, for eMBB, it mainly emphasizes high peak transmission rate, low requirement for delay (no need for low delay), and medium reliability ...
