`
`COMMUNICATIONS METHOD, APPARATUS AND COMPUTER PROGRAM
`
`Field
`
`This disclosure relates to communications, and more particularly to a method,
`
`5
`
`apparatus and computer program in a wireless communication system. In particular
`
`but not exclusively, some embodiments relate to use of bandwidth parts.
`
`Background
`
`A communication system can be seen as a facility that enables communication
`
`between two or more devices such as user terminals, machine-like terminals, base
`
`10
`
`stations and/or other nodes by providing communication channels for carrying
`
`information between the communicating devices. A communication system can be
`
`provided for example by means of a communication network and one or more
`
`compatible communication devices. The communication may comprise, for example,
`
`communication of data for carrying data for voice, electronic mail (email), text
`
`15 message, multimedia and/or content data communications and so on. Non-limiting
`
`examples of services provided
`
`include
`
`two-way or multi-way calls, data
`
`communication or multimedia services and access to a data network system, such
`
`as the Internet.
`
`In a wireless system at least a part of communications occurs over wireless
`
`20
`
`interfaces. Examples of wireless systems include public land mobile networks
`
`(PLMN), satellite based communication systems and different wireless
`
`local
`
`networks, for example wireless local area networks (WLAN). A local area wireless
`
`networking technology allowing devices to connect to a data network is known by the
`
`tradename WiFi (or Wi-Fi). WiFi is often used synonymously with WLAN. The
`
`25 wireless systems can be divided into cells, and are therefore often referred to as
`
`cellular systems. A base station provides at least one cell.
`
`A user can access a communication system by means of an appropriate
`
`communication device or terminal capable of communicating with a base station.
`Hence nodes like base stations are often referred to as access points. A
`
`30
`
`communication device of a user is often referred to as user equipment (UE). A
`
`communication device
`
`is provided with an appropriate signal receiving and
`
`transmitting apparatus
`
`for enabling communications,
`
`for example enabling
`
`communications with the base station and/or communications directly with other user
`

`
`

`

`WO 2019/068224
`
`PCT/CN2017/105273
`
`devices. The communication device can communicate on appropriate channels, e.g.
`
`listen to a channel on which a station, for example a base station of a cell, transmits.
`
`A communication system and associated devices
`
`typically operate
`
`in
`
`accordance with a given standard or specification which sets out what the various
`
`5
`
`entities associated with the system are permitted to do and how that should be
`
`achieved. Communication protocols and/or parameters which shall be used for the
`
`connection are also typically defined. Non-limiting examples of standardised radio
`
`access technologies include GSM (Global System for Mobile), EDGE (Enhanced
`
`Data for GSM Evolution) Radio Access Networks (GERAN), Universal Terrestrial
`
`10 Radio Access Networks (UTRAN) and evolved UTRAN (E-UTRAN). An example
`
`communication system architecture is the long-term evolution (L TE) of the Universal
`
`Mobile Telecommunications System (UMTS) radio-access technology. The L TE is
`
`standardized by the third Generation Partnership Project (3GPP). The L TE employs
`
`the Evolved Universal Terrestrial Radio Access Network (E-UTRAN) access and a
`
`15
`
`further development thereof which is sometimes referred to as L TE Advanced (L TE(cid:173)
`
`A).
`
`Since introduction of fourth generation (4G) services increasing interest has
`
`been paid to the next, or fifth generation (5G) standard. 5G may also be referred to
`
`as a New Radio (NR) network. Standardization of 5G or New Radio networks is an
`
`20
`
`on-going study item.

`node can be, for example, a base station or an eNodeB (eNB), or in a 5G system a
`
`Next Generation NodeB (gNB), or other wireless infrastructure node. These nodes
`
`5 will be generally referred to as base stations. Base stations are typically controlled by
`
`at least one appropriate controller apparatus, so as to enable operation thereof and
`
`management of mobile communication devices in communication with the base
`
`stations. The controller apparatus may be located in a radio access network (e.g.
`
`wireless communication system 100) or in a core network (CN) (not shown) and may
`
`10
`
`be implemented as one central apparatus or its functionality may be distributed over
`
`several apparatus. The controller apparatus may be part of the base station and/or
`
`provided by a separate entity such as a Radio Network Controller. In Figure 1 control
`
`apparatus 1 08 and 1 09 are shown to control the respective macro level base
`
`stations 106 and 107. In some systems, the control apparatus may additionally or
`
`15
`
`alternatively be provided in a radio network controller. Other examples of radio
`
`access system comprise those provided by base stations of systems that are based
`
`on technologies such as 5G or new radio, wireless local area network (WLAN)
`
`and/or WiMax (Worldwide Interoperability for Microwave Access). A base station can
`
`provide coverage for an entire cell or similar radio service area.
`
`20
`
`In Figure 1 base stations 106 and 107 are shown as connected to a wider
`
`communications network 113 via gateway 112. A further gateway function may be
`
`provided to connect to another network.
`
`The smaller base stations 116, 118 and 120 may also be connected to the
`
`network 113, for example by a separate gateway function and/or via the controllers
`
`25
`
`of the macro level stations. The base stations 116, 118 and 120 may be pico or
`
`femto level base stations or the like. In the example, stations 116 and 118 are
`
`connected via a gateway 111 whilst station 120 connects via the controller apparatus
`
`108. In some embodiments, the smaller stations may not be provided.
`A possible wireless communication device will now be described in more
`
`30
`
`detail with reference to Figure 2 showing a schematic, partially sectioned view of a
`
`communication device 200. Such a communication device is often referred to as
`
`user equipment (UE) or terminal. An appropriate mobile communication device may
`
`be provided by any device capable of sending and receiving radio signals. Non(cid:173)
`
`limiting examples comprise a mobile station (MS) or mobile device such as a mobile

`
`phone or what is known as a 'smart phone', a computer provided with a wireless
`
`interface card or other wireless interface facility (e.g., USB dongle), personal data
`
`assistant (PDA) or a tablet provided with wireless communication capabilities, or any
`
`combinations of these or the like. A mobile communication device may provide, for
`
`5
`
`example, communication of data for carrying communications such as voice,
`
`electronic mail (email), text message, multimedia and so on. Users may thus be
`
`offered and provided numerous services via their communication devices. Non(cid:173)
`
`limiting examples of these services comprise two-way or multi-way calls, data
`
`communication or multimedia services or simply an access
`
`to a data
`
`10
`
`communications network system, such as the Internet. Users may also be provided
`
`broadcast or multicast data. Non-limiting examples of
`
`the content comprise
`
`downloads, television and radio programs, videos, advertisements, various alerts
`
`and other information.
`
`A wireless communication device may be for example a mobile device, that is,
`
`15
`
`a device not fixed to a particular location, or it may be a stationary device. The
`
`wireless device may need human interaction for communication, or may not need
`
`human interaction for communication. In the present teachings the terms UE or "user"
`
`are used to refer to any type of wireless communication device.
`
`The wireless device 200 may receive signals over an air or radio interface 207
`
`20
`
`via appropriate apparatus for receiving and may transmit signals via appropriate
`
`apparatus for transmitting radio signals.
`
`In Figure 2 transceiver apparatus is
`
`designated schematically by block 206. The transceiver apparatus 206 may be
`
`provided for example by means of a radio part and associated antenna arrangement.
`
`The antenna arrangement may be arranged internally or externally to the wireless
`
`25
`
`device. The transceiver apparatus may comprise a tuner 210 which tunes the
`
`transceiver to the desired receiving frequency.
`
`A wireless device is typically provided with at least one data processing entity
`
`201, at least one memory 202 and other possible components 203 for use in
`software and hardware aided execution of tasks it is designed to perform, including
`
`30
`
`control of access
`
`to and communications with access systems and other
`
`communication devices. The data processing, storage and other relevant control
`
`apparatus can be provided on an appropriate circuit board and/or in chipsets. This
`
`feature is denoted by reference 204. The user may control the operation of the
`
`wireless device by means of a suitable user interface such as key pad 205, voice

`
`commands, touch sensitive screen or pad, combinations thereof or the like. A display
`
`208, a speaker and a microphone can be also provided. Furthermore, a wireless
`
`communication device may comprise appropriate connectors (either wired or
`
`wireless) to other devices and/or for connecting external accessories, for example
`
`5
`
`hands-free equipment, thereto. The communication devices 102, 104, 105 may
`
`access the communication system based on various access techniques.
`
`Figure 3 shows an example of a control apparatus. This control apparatus
`
`may, for example, be provided in a base station or a gNB. The control apparatus 300
`
`comprises at least one memory 301, at least one data processing unit 302, 303 and
`
`10
`
`an input/output interface 304. Via the interface the control apparatus can be coupled
`
`to a receiver and a transmitter of the base station. The receiver and/or the
`
`transmitter may be implemented as a radio front end or a remote radio head. For
`
`example the control apparatus 300 or processor 301 can be configured to execute
`
`an appropriate software code to provide the control functions.

`
`In NR, new concept of bandwidth part (BWP) has been introduced where
`
`each UE may be operating on different bandwidth part within a single wideband
`
`carrier. It is defined in 3GPP TS 38.211 V1 .0.0 (section 4.4.5) as a contiguous
`
`subset of the physical resource blocks for a given numerology on a given carrier. As
`
`opposed to previous 3GPP systems, where system bandwidth was cell-specific,
`
`20
`
`bandwidth parts can be configured specifically for particular UEs only using
`
`dedicated signalling from gNB and may, e.g. depend on UE's ca
