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 the preferred embodiment, when the scheduling unit is selected, the reservation unit and / or unknown scheduling unit and / or the random access channel (RACH) schedule after the start schedule unit are selected. The unit is excluded, and select in the uplink scheduling unit and the downlink scheduling unit. Wherein, 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 a schedule unit that is upstream. If it is a schedule unit that is the main schedule unit, the number of uplink symbols containing the master's master's schedule is required to meet the requirements. If it is a mandatory unit, the maximum number of schedule components containing the landmark unit satisfies the requirements.

[0172]The base station and the UE respectively derive the scheduling unit from the start scheduling unit from the start scheduling unit, respectively, and mapping in ...

Embodiment 2

[0182]In the preferred embodiment, when the schedule unit is selected, the downlink scheduling unit and / or the reserved scheduling unit and / or the unknown scheduling unit and / or the RACH scheduling unit are excluded in the uplink schedule. Select in the unit. Wherein, 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 a schedule unit that is upstream. If it is a schedule unit that is the main schedule unit, the number of uplink symbols containing the master's master's schedule is required to meet the requirements.

[0183]The base station and the UE respectively derive the scheduling unit from the start scheduling unit from the start scheduling unit, respectively, and mapping in the scheduling unit in the derived scheduling unit. Specifically: excludes the downlink scheduling unit and / or the reserved scheduling unit and / or the UNKNOWN scheduling unit ...

Embodiment 3

[0188]In the present preferred embodiment, when the scheduling unit is selected, the PUCCH is required to include the number of symbols and the symbol position in the plurality of slot when the PUCCH is across multiple SLOT. If the scheduling unit has a number of symbols and symbols that meet the requirements, the scheduling unit is considered to be a SLOT across multiple slot as a PUCCH.

[0189]The base station and the UE respectively derive the scheduling unit from the start scheduling unit from the start scheduling unit, respectively, and mapping in the scheduling unit in the derived scheduling unit. Specifically: Requires PUCCH across multiple slots, and the PUCCH contains the same number and symbol position in the plurality of SLOTs. If the scheduling unit has a number of symbols and symbols that meet the requirements, the scheduling unit is considered to be a SLOT across multiple slot as a PUCCH. There is no type of Slot here, just in accordance with the number of available upli...

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. The method comprises the following steps that: according to the number of scheduling units occupied by an uplink control channel of user equipment, an initial scheduling unit used by the uplink control channel, an initial symbol position of the uplink control channel in the initial scheduling unit, the number of symbols used by the uplink control channel and an agreed rule, a subsequent scheduling unit used by the uplink control channel is determined, and / or the position of a symbol used by the uplink control channel in the subsequent scheduling unit is determined. 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 uplink control channel across time slots is solved.

Description

[0001]The present application is Application No. 201711107748.1, and the application date is November 10, 2017, the presentation of the presentation of the "one method, base station and user equipment" of an upside control channel scheduling unit is applied.Technical field[0002]The present invention relates to the field of wireless communication, and more particularly to a method, base station, and user equipment for an uplink control channel scheduling unit.Background technique[0003]5G NR (New Radio) is a research project for 3GPP (third-generation partners), which determines a new wireless air interface standard based on orthogonal frequency division multiplexing (OFDM), and will become the basis for next-generation mobile networks. .[0004]In the NR system, the scheduling unit (such as a slot (slot), which is described below with a Slot as an example), and can be flexibly configured by the base station, typical SLOT can consist of one or more of the following: downlink The transmi...
