example 1

[0189] A1 slot values ​​are defined in advance (without distinguishing numerology), and a slot value is selected from the A1 slot values ​​to notify the UE.

[0190] For example, the protocol pre-defines [1-32] a number of slot values ​​that increase with a step size of P.

[0191] Wherein, P can be a natural number, or P is 1, or P is a multiple of 2, or P is a power of an exponent of 2, and so on.

[0192] For example: the protocol pre-defines [1~32] 32 slot values ​​with a step size of 1, or pre-defines [1~32] 16 slot values ​​with a step size of 2, or pre-defines [1 ~32] 8 slot values ​​with a step size of 4 increments, and so on, or pre-defined [1, 2, 4, 8, 16, 32]; the UE will be notified of the selected value of a slot.

example 2

[0194] Define A2 slot values ​​in advance (no distinction between numerology), select B1 slot values ​​from them, pre-configure the B1 slot values ​​for the UE through high-level signaling, and select a slot from the B1 slot values ​​assigned to the UE The value is notified to the UE.

[0195] For example, the protocol pre-defines [1-32] a number of slot values ​​that increase with a step size of P.

[0196] Wherein, P can be a natural number, or P is 1, or P is a multiple of 2, or P is a power of an exponent of 2, and so on.

[0197] For example: the protocol pre-defines [1~32] 32 slot values ​​with a step size of 1, or pre-defines [1~32] 16 slot values ​​with a step size of 2, or pre-defines [1 ~32] 8 slot values ​​with a step size of 4, and so on, or pre-defined [1,2,4,8,16,32].

[0198] Select B1 slot values ​​from the above-mentioned predefined time slot number set to inform the UE through high-level signaling, for example, B1=3 or 4, and then through the DCI The indi...

example 3

[0200] For each numerology, the values ​​of A3 slots are predefined, and the values ​​of A3 slots corresponding to different numerology can be the same or different, and the corresponding slot number set can be determined according to the numerology, and a slot can be selected from the determined slot number set values ​​to inform the UE.

[0201] For example: the protocol pre-defines the number of slots for each numerology as shown in Table 1, where μ represents the number of different numerology, the second column is the subcarrier spacing Δf corresponding to different numerology, then the UE and the base station can use The numerology can pre-determine the corresponding slot number set, and then indicate one of the slot number values ​​to the UE through high-level signaling or the indication field in the DCI.

Abstract

The embodiment of the invention provides a method and apparatus for multi-slot transmission. The method comprises the following steps: determining a time slot number value in a time slot number set; And sending the time slot number values to a user terminal, wherein the time slot number values are used for the user equipment to perform multi-time slot physical uplink control channel PUCCH and / or physical uplink shared channel PUSCH transmission. Thus, the UE can determine the slot number values from the pre-configured time slot number set according to the configuration of the network side, sothat multi-slot PUCCH and / or PUSCH transmission can be carried out, and the performance and uplink coverage of the PUCCH and / or PUSCH transmission are improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and device for multi-slot (slot) transmission. Background technique [0002] With the development and change of mobile communication service requirements, organizations such as ITU (International Telecommunication Union, International Telecommunication Union) and 3GPP have begun to study new wireless communication systems (such as 5G NR (5Generation New RAT)). A new frame structure is defined in a new wireless communication system, which supports different baseband parameters (numerology, including parameters such as subcarrier spacing, etc.). For different baseband parameters, it is defined that the length of a subframe is always 1ms (milliseconds), and a subframe contains A slots, corresponding to different baseband parameters, the number of A may be different, so that the length of a subframe is 1ms . For different baseband parameters, a slot can conta...
