Problems solved by technology

[0005] In related technologies, on the one hand, UEs can only be configured with PUCCH resources that occupy fewer symbols in the time domain, which affects the uplink coverage of PUCCH channels; on the other hand, configuring multiple sets of PUCCH resources will cause a problem of high signaling overhead

example 1

[0080] A specific embodiment of the present disclosure provides a resource configuration method, the method including:

[0081] Step S610: Configure the same physical uplink control channel resource set for the sub-slots included in one time slot.

[0082] Here, the PUCCH resource set includes: one or more PUCCH resources. Here, multiple sub-slots in one slot share a set of PUCCH resources, that is to say, different sub-slots have the same PUCCH resources.

[0083] Step S620: When the time domain symbols occupied by the first PUCCH resource in the PUCCH resource set exceed the boundary of the time slot, discard the entire first PUCCH resource or a part of the first PUCCH resource.

[0084] Here, although the PUCCH resources are the same, for a specific sub-slot, if the length of the time domain symbol occupied by a certain PUCCH resource exceeds the time slot boundary, the PUCCH resource will be discarded. Can include the following two methods:

[0085] Method 1: see again ...

example 2

[0090] Another specific embodiment of the present disclosure provides a resource configuration method, the method includes:

[0091] Step S710: Configure multiple sets of PUCCH resource sets for sub-slots contained in a time slot; wherein, each set of PUCCH resource sets is applicable to one or more sub-slots contained in a time slot, and the PUCCH resource set includes: one or more PUCCH resources.

[0092] Here, multiple sets of PUCCH resource sets are configured, and for each set of PUCCH resource sets, it is specified which sub-slots in the time slot it applies to. In this specific embodiment, the time-domain symbol lengths included in the divided 4 sub-slots are 3, 4, 3, and 4 respectively. For two 4-symbol sub-slots, a set of PUCCH resource sets can be shared, and the corresponding configuration A ; For two 3-symbol sub-slots, a set of PUCCH resource sets can be shared, corresponding to configuration B. In configuration A, PUCCH resources occupying 4 time domain symbol...

Abstract

The invention relates to a PUCCH resource configuration method. The method comprises the steps: configuring the same PUCCH resource set for a sub-time slot contained in a time slot, wherein the PUCCHresource set comprises one or more PUCCH resources; and when the time domain symbol occupied by the first PUCCH resource in the PUCCH resource set exceeds the boundary of the time slot, discarding thefirst PUCCH resource.

Description

technical field [0001] The present disclosure relates to the technical field of wireless communication but is not limited to the technical field of wireless communication, and particularly relates to a method and device for resource allocation of a Physical Uplink Control Channel (PUCCH, Physical Uplink Control Channel), a communication device, and a storage medium. Background technique [0002] In 5G New Radio (NR, New Radio), Ultra Reliable and Low Latency Communication (URLLC, Ultra Reliable and Low Latency Communication) service is a very important service type, which will be widely used in factory automation, remote control, augmented reality (AR , Augmented Reality) / Virtual Reality (VR, Virtual Reality) and other 5G scenarios. [0003] Time domain resources can be divided into time slots and sub-slots; wherein, a time slot can include one or more sub-slots. [0004] The PUCCH can be used to transmit various uplink control information; resources allocated to the PUCCH ...
