`Authorization or Opt-Out of Authorization to Permit Access:
`
`When this Application Data Sheet is properly signed and filed with the application, applicant has provided written
`authority to permit a participating foreign intellectual property (IP) office access to the instant application-as-filed (see
`paragraph A in subsection 1 below) and the European Patent Office (EPO) access to any search results from the instant
`application (see paragraph Bin subsection 1 below).
`
`Should applicant choose not to provide an authorization identified in subsection 1 below, applicant must opt-out of the
`authorization by checking the corresponding box A or B or both in subsection 2 below.
`
`NOTE: This section of the Application Data Sheet is ONLY reviewed and processed with the INITIAL filing of an
`application. After the initial filing of an application, an Application Data Sheet cannot be used to provide or rescind
`authorization for access by a foreign IP office(s). Instead, Form PTO/SB/39 or PTO/SB/69 must be used as appropriate.
`
`1. Authorization to Permit Access by a Foreign Intellectual Property Office(s)
`
`A. Priority Document Exchange (PDX) - Unless box A in subsection 2 (opt-out of authorization) is checked, the
`undersigned hereby grants the USPTO authority to provide the European Patent Office (EPO), the Japan Patent Office
`(JPO), the Korean Intellectual Property Office (KIPO), the State Intellectual Property Office of the People's Republic of
`China (SIPO}, the World Intellectual Property Organization (WIPO), and any other foreign intellectual property office
`participating with the USPTO in a bilateral or multilateral priority document exchange agreement in which a foreign
`application claiming priority to the instant patent application is filed, access to: (1) the instant patent application-as-filed
`and its related bibliographic data, (2) any foreign or domestic application to which priority or benefit is claimed by the
`instant application and its related bibliographic data, and (3) the date of filing of this Authorization. See 37 CFR 1.14(h)
`(1 ).
`
`B. Search Results from U.S. Application to EPO - Unless box Bin subsection 2 (opt-out of authorization) is checked,
`the undersigned hereby grants the USPTO authority to provide the EPO access to the bibliographic data and search
`results from the instant patent application when a European patent application claiming priority to the instant patent
`application is filed. See 37 CFR 1.14(h)(2).
`
`The applicant is reminded that the EPO's Rule 141(1) EPC (European Patent Convention) requires applicants to submit a
`copy of search results from the instant application without delay in a European patent application that claims priority to
`the instant application.
`
`2. Opt-Out of Authorizations to Permit Access by a Foreign Intellectual Property Office(s)
`
`A. Applicant DOES NOT authorize the USPTO to permit a participating foreign IP office access to the instant
`D application-as-filed. If this box is checked, the USPTO will not be providing a participating foreign IP office with
`any documents and information identified in subsection 1A above.
`
`B. Applicant DOES NOT authorize the USPTO to transmit to the EPO any search results from the instant patent
`D application. If this box is checked, the USPTO will not be providing the EPO with search results from the instant
`application.
`NOTE: Once the application has published or is otherwise publicly available, the USPTO may provide access to the
`application in accordance with 37 CFR 1.14.

`
`METHODS AND APPARATUS FOR REQUESTING SYSTEM INFORMATION IN A
`WIRELESS COMMUNICATION NETWORK
`
`5
`
`Technical Field
`
`The present disclosure relates to methods and apparatus for requesting system information
`
`in a terminal device for a wireless network.
`
`Background
`
`10
`
`Efforts are on-going to develop and standardize communications networks and protocols
`
`intended to meet the requirements set out for the fifth generation (5G) of wireless systems,
`as defined by the Next Generation Mobile Networks Alliance. The new system (also known
`
`as "New Radio" or "NR") is being designed to support lean carrier operation, where only
`
`absolutely necessary information is transmitted, preferably in a dedicated manner to the UE.
`
`15
`
`This aim has a large impact on the design of the system information mechanisms for NR, as
`
`system information until now has always been transmitted and broadcast to all UEs in a cell.
`
`Furthermore, system information and initial access design is not as easy to modify or
`
`enhance in later releases as features require primarily dedicated signaling.
`
`20
`
`In order to minimize the amount of system information broadcast, on-demand delivery of
`
`parts of the system information may be introduced.
`
`Figure 1 illustrates on-demand signaling for delivery of parts of the system information. For
`this on-demand delivery the system information (SI) may be divided into Minimum SI and
`
`25 Other SI. Minimum SI 101 is periodically broadcast from the Node B 102 and received by the
`
`user equipment (UE) 103. The Minimum SI 101 comprises basic information required for
`initial access to the network and information for acquiring any other SI broadcast periodically
`
`or provisioned on-demand, i.e. scheduling information. The Other SI 104 encompasses
`
`everything not broadcast in the Minimum SI 101 and may either be broadcast, or provisioned
`
`30
`
`in a dedicated manner, either triggered by the network or upon request from the UE.
`
`For UEs operating in a connected state (i.e. RRC_CONNECTED), dedicated radio resource
`
`control (RRC) signaling can be used for the request and delivery of the Other SI. The Other
`
`SI may be broadcast at a configurable periodicity and for a certain duration. It is a network
`
`35
`
`decision whether the Other SI is broadcast or delivered through dedicated and UE specific
`
`RRC signaling.

`
`Each cell on which the UE is allowed to camp broadcasts at least some contents of the
`
`Minimum SI, while there may be cells in the system on which the UE cannot camp and do
`
`not broadcast the Minimum SI.
`
`For a cell/frequency that is considered for camping by the UE, the UE is not required to
`
`acquire the contents of the Minimum SI of that cell/frequency from another cell/frequency
`
`layer. This does not preclude the case that the UE applies stored SI from previously visited
`
`cell(s).
`
`If the UE cannot determine the full contents of the Minimum SI of a cell (by receiving from
`
`that cell or from valid stored SI from previous cells), the UE may consider that cell as barred.
`
`5
`
`10
`
`In addition, for an on demand request of broadcast SI transmission a UE operating in an idle
`
`15
`
`or inactive mode the network may control whether the request for Other system information
`
`is transmitted by a random access preamble message or as part of a radio resource control
`
`connection message.
`
`If the Physical Random Access Channel (PRACH) preamble and/or PRACH resource
`
`20
`
`specific to each system information block (SIB) or set of SIBs which the UE needs to acquire
`
`is included in minimum SI, then the SI request may be indicated using the random access
`
`preamble.
`
`If the PRACH preamble and/or PRACH resource specific to each SIB or set of SIBs which
`
`25
`
`the UE needs to acquire is not included in the minimum SI, then the SI request may be
`
`included as part of a radio resource control connection message.
`
`Summary
`
`The current solution does not cover any error cases when UE requests on-demand system
`
`30
`
`information. For example, the request from the UE may not be received correctly by the
`
`network, or may collide with a request from another UE or the UE may not be able to receive
`
`the on-demand SIB transmission from the network. Based on currently agreed procedure,
`
`the UE may not be able to fully function in the system even for relatively minor errors in the
`
`on-demand system information procedure.

`
`According to a first aspect of the disclosure there is provided a method of requesting system
`
`information in a terminal device for a wireless network. The method comprises receiving,
`
`from a network node of the wireless network, a first portion of system information comprising
`
`an indication of a second portion of system information which is available upon request. The
`
`5 method also comprisestransmitting, to the network node, a first request requesting that the
`
`second portion of system information be transmitted to the terminal device; and responsive
`
`to a determination that the requested second portion of system information has not been
`
`received successfully by the terminal device, transmitting, to the network node, a second
`
`request for the second portion of system information.
