Problems solved by technology

When the base station configures a PUCCH that spans multiple slots for the UE, the base station will notify the UE of the starting slot of the PUCCH and the number of slots that need to be crossed. For example, the base station will notify the UE that the starting slot of the PUCCH that spans multiple slots is slot n , the number of cross-slots needs to be 4. However, since the structure of the slot is dynamically changing, that is, the slot structure after slot n has a slot with downlink as the main slot (there are more downlink OFDM symbols in the slot than uplink OFDM symbols), and uplink OFDM symbols The main slot (there are more uplink OFDM symbols than downlink OFDM symbols in the slot), pure uplink slot, pure downlink slot, reserved slot, etc., how to choose the remaining 3 slots of the UE except the initial slot, has not yet been come up with effective solutions

Embodiment 1

[0171] In this preferred embodiment, when the scheduling unit is selected, the reserved scheduling unit and / or the unknown (Unknown) scheduling unit and / or the random access channel (Random Access Channel, RACH) after the initial scheduling unit are scheduled The unit is excluded and selected from the uplink scheduling unit and the downlink scheduling unit. The downlink scheduling unit includes a pure downlink scheduling unit and a downlink-based scheduling unit. The uplink scheduling unit includes a pure uplink scheduling unit and an uplink-based scheduling unit. If it is an uplink-dominant scheduling unit, the number of uplink symbols contained in the uplink-dominant scheduling unit is required to meet the requirements. If it is a downlink-dominant scheduling unit, the number of uplink symbols contained in the downlink-dominant scheduling unit is required to meet the requirements.

[0172] The base station and the UE respectively deduce the scheduling unit used by the PUCC...

Embodiment 2

[0182] In this preferred embodiment, when selecting a scheduling unit, the downlink scheduling unit and / or the reserved scheduling unit and / or the Unknown scheduling unit and / or the RACH scheduling unit after the initial scheduling unit are excluded, and the uplink scheduling unit is unit selection. The downlink scheduling unit includes a pure downlink scheduling unit and a downlink-based scheduling unit. The uplink scheduling unit includes a pure uplink scheduling unit and an uplink-based scheduling unit. If it is an uplink-dominant scheduling unit, the number of uplink symbols contained in the uplink-dominant scheduling unit is required to meet the requirements.

[0183] The base station and the UE respectively deduce the scheduling unit used by the PUCCH and the mapping of the PUCCH in the derived scheduling unit from the initial scheduling unit according to the rules. Specifically, the downlink scheduling unit and / or the reserved scheduling unit and / or the Unknown schedu...

Embodiment 3

[0188] In this preferred embodiment, when selecting a scheduling unit, it is required that when the PUCCH spans multiple slots, the PUCCH includes the same number of symbols and the same symbol positions in the multiple slots. If the scheduling unit has the required number of symbols and symbol positions, the scheduling unit is regarded as a slot that spans multiple slots as a PUCCH.

[0189] The base station and the UE respectively deduce the scheduling unit used by the PUCCH and the mapping of the PUCCH in the derived scheduling unit from the initial scheduling unit according to the rules. Specifically, the PUCCH is required to span multiple slots, and the PUCCH includes the same number of symbols and the same symbol positions in the multiple slots. If the scheduling unit has the required number of symbols and symbol positions, the scheduling unit is regarded as a slot that spans multiple slots as a PUCCH. There is no distinction between the types of slots here. It is only ...

Abstract

The invention discloses a method for determining an uplink control channel scheduling unit, a base station, user equipment and a computer-readable storage medium, including: the base station according to the number of scheduling units occupied by the uplink control channel of the user equipment, the starting time of the uplink control channel use The initial scheduling unit, the starting symbol position of the uplink control channel in the initial scheduling unit, the number of symbols used, and the agreed rules, determine the subsequent scheduling units used by the uplink control channel, and / or the The position of the symbol used by the uplink control channel in the subsequent scheduling unit. By determining the scheduling unit used by the uplink control channel of the user equipment according to the agreed rules, the invention solves the problem of how to select other time slots after the initial time slot for the uplink control channel across time slots.

Description

[0001] This application is a divisional application with the application number of 201711107748.1, the filing date of which is on November 10, 2017, and the title of the invention is "a method for determining an uplink control channel scheduling unit, a base station and a user equipment". technical field [0002] The present invention relates to the technical field of wireless communication, and in particular, to a method for determining an uplink control channel scheduling unit, a base station and a user equipment Background technique [0003] 5G NR (New Radio) is an ongoing 3GPP (3rd Generation Partnership) research project that defines a new wireless air interface standard based on Orthogonal Frequency Division Multiplexing (OFDM) and will be the basis for next-generation mobile networks . [0004] In the NR system, there are various structures of the scheduling unit (such as a time slot (slot), which is explained below by taking the slot as an example), which can be flex...
