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

[0170] In this preferred embodiment, when the scheduling unit is selected, the reserved scheduling unit and / or unknown (Unknown) scheduling unit and / or random access channel (Random Access Channel, RACH) after the initial scheduling unit are scheduled The unit is excluded and selected between the uplink scheduling unit and the downlink scheduling unit. Wherein, the downlink scheduling unit includes a pure downlink scheduling unit and a downlink main scheduling unit. The uplink scheduling unit includes a pure uplink scheduling unit and an uplink main scheduling unit. If it is an uplink-master scheduling unit, it is required that the number of uplink symbols included in the uplink-master scheduling unit meets the requirements. If it is a downlink-master scheduling unit, it is required that the number of uplink symbols included in the downlink-master scheduling unit meets the requirements.

[0171] The base station and the UE respectively derive the scheduling unit used by the ...

Embodiment 2

[0181] In this preferred embodiment, when selecting a scheduling unit, the downlink scheduling unit and / or reserved scheduling unit and / or Unknown scheduling unit and / or RACH scheduling unit after the initial scheduling unit are excluded, and the uplink scheduling unit Select from the unit. Wherein, the downlink scheduling unit includes a pure downlink scheduling unit and a downlink main scheduling unit. The uplink scheduling unit includes a pure uplink scheduling unit and an uplink main scheduling unit. If it is an uplink-master scheduling unit, it is required that the number of uplink symbols included in the uplink-master scheduling unit meets the requirements.

[0182] The base station and the UE respectively derive the scheduling unit used by the PUCCH and the mapping of the PUCCH in the derived scheduling unit backward from the initial scheduling unit according to the rules. Specifically: exclude the downlink scheduling unit and / or the reserved scheduling unit and / or th...

Embodiment 3

[0187] In this preferred embodiment, when the scheduling unit is selected, it is required that when the PUCCH spans multiple slots, the number of symbols and symbol positions contained in the PUCCH in the multiple slots are the same. If the scheduling unit has the number of symbols and symbol positions that meet the requirements, the scheduling unit is considered as a slot that spans multiple slots for the PUCCH.

[0188] The base station and the UE respectively derive the scheduling unit used by the PUCCH and the mapping of the PUCCH in the derived scheduling unit backward from the initial scheduling unit according to the rules. Specifically, it is required that the PUCCH spans multiple slots, and the number of symbols and symbol positions contained in the PUCCH in the multiple slots are the same. If the scheduling unit has the number of symbols and symbol positions that meet the requirements, the scheduling unit is considered as a slot that spans multiple slots for the PUCCH...

Abstract

The invention discloses a method for determining an uplink control channel scheduling unit. The invention discloses a base station, user equipment and a computer readable storage medium. The method comprises the following steps that: a base station determines a subsequent scheduling unit used by the uplink control channel, and / or a location of a symbol used by the uplink control channel in the subsequent scheduling unit according to the number of scheduling units occupied by the uplink control channel of user equipment, the starting symbol position of the uplink control channel in the initialscheduling unit, and the number of used symbols, and a predetermined rule. According to the invention, the scheduling unit used by the uplink control channel of the user equipment is determined according to the agreed rule, so that the problem of how to select other time slots after the starting time slot of the cross-time-slot uplink control channel is solved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for determining an uplink control channel scheduling unit, a base station and user equipment. Background technique [0002] 5G NR (New Radio) is an ongoing 3GPP (Third Generation Partnership) research project, which determines a new wireless air interface standard based on Orthogonal Frequency Division Multiplexing (OFDM), and will become the basis of the next generation of mobile networks . [0003] In the NR system, there are various structures of scheduling units (such as time slots (slots), which are described below as examples), which can be flexibly configured by the base station. A typical slot can consist of one or more of the following parts: downlink The transmission part, the uplink transmission part, the guard interval (GAP) part, and the number of OFDM symbols occupied by each part are configurable. That is to say, the number of OFDM...
