Problems solved by technology

[0007] Therefore, the base station in the above scenario cannot transmit DCI to the user equipment in a suitable CORESET
In case the user equipment fails to obtain DCI, the base station cannot schedule downlink or uplink transmission for the user equipment

Embodiment Construction

[0045] figure 1 An example wireless communication network 100 is depicted in which devices such as base stations and user devices (also referred to as user equipment or UEs) communicate using unlicensed portions of the radio spectrum. Since the following examples mainly refer to 5G NR technology, these unlicensed parts of the radio spectrum are called NR-U.

[0046] Wireless communication network 100 in an example configuration includes UE 102, which may be any suitable device capable of wireless communication (this is discussed further below). The wireless communication network 100 also includes a 5G NR base station 104 connected to a CN 106 of core network (CN) type 5GC. The 5G NR base station 104 thus operates as a next generation Node B (gNB). However, in other embodiments, the wireless communication network 100 may include one or more base stations operating according to a type of radio access technology (RAT) other than NR, and these base stations may be connected to CN...

Abstract

Allocating resources to user devices (102, 110, 112) in a base station (104) includes transmitting, to a user device, indications of a first time-frequency resource including a first frequency sub-band within a bandwidth part allocated in an unlicensed spectrum and a second time-frequency resource including a second frequency sub-band within the bandwidth part (1702), performing (1704) a channel access procedure on the first channel corresponding to the first frequency sub-band, and a second channel corresponding to the second frequency sub-band, to obtain the channel occupancy time on at least one of the first channel or the second channel; and transmitting (1706), within the obtained channel occupancy time on at least one of the first channel or the second channel, the downlink control information (DCI) to a user device over a first time-frequency resource that includes the first frequency sub-band or a second time-frequency resource that includes the second frequency sub-band.

Description

technical field [0001] The present disclosure relates to wireless communications, and more particularly to allocating resources in unlicensed portions of the spectrum for wireless communications. Background technique [0002] The background description provided herein is for the purpose of generally presenting the context of the disclosure. The work of the presently named inventors, to the extent described in this Background section, and aspects described that may not qualify as prior art at the time of filing, are not admitted, expressly or impliedly, as part of the present disclosure current technology. [0003] In some cases, base stations and user equipment operating in wireless communication networks may utilize portions of the licensed and unlicensed radio spectrum. For example, 5G New Radio (NR) supports operation in unlicensed spectrum (commonly referred to as NR-U). One of the requirements of NR-U is integration with other radio access technologies such as (IEE...
