DECLARATION OF LORENZO CASACCIA

I, Lorenzo Casaccia, hereby declare as follows:

1. I am currently a Vice President of Engineering of Qualcomm Technologies, Inc. I 

have been employed by Qualcomm since the year 2000. In 2000, I obtained a laurea degree in 

electrical engineering from the Polytechnic University of Turin, and a telecommunications degree 

from the Eurecom Institute of Sophia Antipolis. I also hold a laurea degree in philosophy and a 

master’s degree in the philosophy of knowledge from the Sapienza University of Rome.

2. I submit this declaration in support of Qualcomm’s Opposition to Motion for Partial 

Summary Judgment on Qualcomm’s Standard Essential Patent Licensing Commitments.

3. I have been a part of Qualcomm’s Standardization and Industry Organization 

(“QSIO”) activities related to 3rd Generation Partnership Project (“3GPP”) cellular standards 

development since 2001. I have led the QSIO team in 3GPP since approximately 2008-2009. In 

these roles, I have been involved in the development of Third Generation (3G), Fourth Generation 

(4G), and Fifth Generation (5G) cellular standards, including, for example:

• 3G UMTS standards for WCDMA and High Speed Packet Access (HSPA) 

(including High Speed Downlink Packet Access (HSDPA), High Speed Uplink 

Packet Access (HSUPA), and Evolved High Speed Packet Access (HSPA+)),

• 4G standards for Long-Term Evolution (LTE) and LTE-Advanced (LTE-A); and 

• 5G New Radio (5G-NR). 

4. I currently oversee over 80 engineers responsible for day-to-day standards 

development and participation within 3GPP in 16 different 3GPP Working Groups. I have 

personally attended over one hundred 3GPP meetings, including 35 Radio Access Network 

(“RAN”) Plenary meetings and over 50 Working Group meetings.

I. Summary

5. I understand that the FTC argues that modem chips implement the Alliance for 

Telecommunications Industry Solutions (ATIS) standards for the 3G UMTS, 4G LTE, and 5G 

wireless standards. As a technical matter, this is incorrect because the ATIS standards have no 

notion or definitional unit that corresponds to a cellular modem chip. Rather, the communications

protocols defined by the ATIS standards concern complete end-user devices (referred to as “User 

Equipment” or “UE”) and their interactions with the cellular network and other complete end-user 

devices. A modem chip standing alone cannot implement the UE-level requirements defined in the 

ATIS Cellular Standards.

6. 3GPP was initially formed in December 1998 when the European 

Telecommunications Standards Institute (ETSI) partnered with other standard development 

organizations (SDOs) from around the world to develop new technologies (or more specifically, 

technology specifications) for the third generation (3G) of cellular networks. ATIS is the North 

American Organizational Partner of 3GPP. 

7. ATIS does not independently develop 3G, 4G, or 5G standards (collectively, “3GPP 

Cellular Standards”). Instead, 3GPP develops technical specifications, which 3GPP’s 

Organizational Partners may then transpose and publish as their own standard. In addition to ATIS, 

the 3GPP Organizational Partners are: ETSI – the European Telecommunications Standards 

Institute (Europe); ARIB – Association of Radio Industries and Businesses (Japan); CCSA – China 

Communications Standards Association (China); TSDSI – Telecommunications Standards 

Development Society, India (India); TTA – Telecommunications Technology Association (Korea); 

and TTC – Telecommunications Technology Committee (Japan). When adopting, or transposing, 

3GPP specifications within their regions, the Organizational Partner SDOs do not change any of 

the substantive text of the 3GPP specification. Any modifications are made only to conform to 

specific local requirements. For this reason, I refer to the 3GPP Cellular Standards and documents 

in this declaration as they were also adopted by ATIS.

8. 3GPP Cellular Standards have no notion of modem chips, and the 3GPP Cellular 

Standards do not define a modem chip or how a modem chip should be implemented. In my years 

of participation in 3GPP activities and supervising others participating in 3GPP, I am not aware of 

any 3GPP project proposals, 3GPP study items, 3GPP Technical Reports, or 3GPP technical 

specifications for cellular modem chips. Instead, the 3GPP Cellular Standards and the development 

efforts underlying these standards address performance, interoperability, and communication 

protocols between the entities that make-up cellular systems, namely, the Core Network, the Access

Network, and the User Equipment (“UE”), which is the device operated by end-users. 

9. 3GPP Cellular Standards do not define how a UE is constructed, whether particular 

functions are implemented in hardware or software, or even the components of a UE. Instead, these 

standards provide UE manufacturers broad discretion regarding how to construct a UE. 

10. More specifically, Cellular Standards do not define a modem chip, and a modem 

chip standing alone cannot implement the Cellular Standards requirements that are defined at the 

UE-level for at least the following reasons, each explained in further detail below, with reference 

to 3GPP Cellular Standards: 

a. First, 3GPP Cellular Standards define interfaces among, and the operation 

of, domains in the cellular system/network. For example, 3GPP TS 23.101

defines 3G UMTS systems in terms of domains, which are the major 

subsystems of the cellular system/network. The basic domain split between 

the “User Equipment Domain” and the “Infrastructure Domain” is shown in 

Figure 1, below. “User Equipment” refers to complete devices such as 

cellular handsets, smartphones, tablets, or other end-user devices. 

“Infrastructure” refers to the network (similar domain splits focused on user 

equipment are discussed in greater detail below for 4G and 5G).

b. Second, beyond defining the UE as including a SIM card, the UE domain is 

not further partitioned, and the UE is the functional element used in 3GPP 

standards descriptions. That is, if the 3GPP Cellular Standards intended to

further parse the UE and specify the inclusion or operation of a particular 

component like a modem chip, it knew how to but did not do so.

c. Third, 3GPP Cellular Standards are voluminous. In the parlance of 3GPP 

Cellular Standards, a technical description in a specification is mandatory if 

it uses the word “shall.” The 3GPP Cellular Standards include thousands of 

instances stating that the “UE shall” meet some particular performance or 

communication requirement. These same standards do not, however, 

discuss—let alone provide—that a “modem chip” (or some equivalent term) 

meet any particular performance or communication requirement. This is 

consistent with the fact that the 3GPP Cellular Standards define the 

requirements of a fully-network operational device like a UE instead of its 

components.

d. Fourth, 3GPP Cellular Standards define and provide for testing to determine 

conformance of devices with the standards’ requirements. These testing 

specifications are at the device level (i.e., the entire UE), defining how an 

individual UE must communicate with and operate in the network. These 

testing specifications do not call for—let alone provide for—any testing of 

modem chips.

II. 3GPP Architectural Domains

11. 3GPP defines an architecture that provides a common framework for the 

development of 3GPP Cellular Standards.

12. Figure 1 of the “General Universal Mobile Telecommunications System (UMTS) 

architecture,” Exhibit 1 to this declaration, illustrates the architectural framework and identifies the 

relationships between functional elements for 3G UMTS systems. Id.

13. The figure above illustrates the “User Equipment Domain” and the “Infrastructure 

Domain” as the two primary domains, where the Infrastructure Domain is further broken down into 

the Access Network Domain and the Core Network Domain. 3GPP Cellular Standards define how 

equipment operated by end-users in the User Equipment Domain interacts with supporting 

infrastructure in the Infrastructure Domain. Generally, “User Equipment” or “UE” refers to devices 

such as cellular handsets, smartphones, tablets, or other end-user devices. “Infrastructure” refers 

to the network. The Access Network Domain refers to base stations and other equipment that 

receive wireless signals from User Equipment, while the Core Network Domain refers to the 

network that transports voice and data, generally over wired connections. Within the User 

Equipment Domain, 3GPP standards occasionally describe the “USIM Domain” and the “Mobile 

Equipment Domain” as sub-elements. USIM is an acronym for Universal Subscriber Identity

Module, also commonly known as a SIM card, while Mobile Equipment refers to everything with 

the UE besides the USIM. 

14. 3GPP Cellular Standards do not dictate the implementation of these individual 

functional elements, but are instead focused on the protocols for communications across the

“reference points” between the functional elements.

15. Akin to the description of 3G UMTS provided above, the functions of the whole 

LTE system are based on the elements shown in Figure 4.2.1-1 of TS 23.401, “3rd Generation 

Partnership Project; Technical Specification Group Services and System Aspects; General Packet 

Radio Service (GPRS) Enhancements for Evolved Universal Terrestrial Radio Access Network 

(E-UTRAN) Access,” provided below. ATIS, "3rd Generation Partnership Project; Technical 

Specification Group Services and System Aspects; General Packet Radio Service (GPRS) 

enhancements for Evolved Universal Terrestrial Radio Access Network (E-UTRAN) access 

(Release 14)," ATIS.3GPP.23.401V1460 (December 2017) (Exhibit 2); see also 3GPP, “3rd 

Generation Partnership Project; Technical Specification Group Services and System Aspects; 

General Packet Radio Service (GPRS) enhancements for Evolved Universal Terrestrial Radio 

Access Network (E-UTRAN) access (Release 14),” TS 23.401 v14.6.0, at 19 (December 2017), 

available at http://www.3gpp.org/dynareport/TSG-WG--S2.htm?Itemid=445 (last accessed 

September 13, 2018). Figure 4.2.1-1 is the non-roaming LTE architecture and illustrates the 

framework and relationships between functional elements for 4G LTE systems. 

Id. The 4G LTE standards specifications define the interfaces between pairs of these elements, 

e.g., the relationship and protocols for communications between the UE and E-UTRAN, defined 

by the LTE-Uu reference point.

16. While the LTE architecture shows more sub-divisions within the Access Network 

(“E-UTRAN”) and Core Network than were shown above for 3G UMTS, the functional element 

defined for end-user devices is still the UE. 

17. Reliance on the UE as the primary functional element for end-user device 

functionality and standards definitions remains true for 5G New Radio (5G-NR) as well, as shown

18. This figure above is from “3rd Generation Partnership Project; Technical 

Specification Group Services and System Aspects; System Architecture for the 5G System; Stage 

2 (Release 15),” attached as Exhibit 3. ATIS, "3rd Generation Partnership Project; Technical 

Specification Group Services and System Aspects; System Architecture for the 5G System; Stage 

2 (Release 15)," ATIS.3GPP.23.501V1520 (June 2018) (Exhibit 3); see also 3GPP, “3rd

2018), available at http://www.3gpp.org/dynareport/TSG-WG--S2.htm?Itemid=445 (last accessed 

September 13, 2018). 

19. As is shown by each of the figures above for 3G, 4G LTE, and 5G-NR, 3GPP 

Cellular Standards subdivide system elements when required to define standardized functionality. 

Nowhere, however, is a modem chip defined as a functional sub-element of the UE in 3GPP 

Cellular Standards.

20. Another example of the 3GPP Cellular Standards’ system architecture defining the 

UE as the primary functional element for end-users is in 3GPP’s System Architecture Working 

Group’s (“SA2”) specifications regarding back-up telephone support when LTE services are not 

available. Here, 2G, 3G, and 4G systems are shown where a UE may “fall-back” on legacy 

networks when LTE connectivity is not available.

(December 2017), available at http://www.3gpp.org/dynareport/TSG-WG--S2.htm?Itemid=445 

(last accessed September 13, 2018). This illustrates that the UE has been the universal functional 

element for cellular system design across multiple generations of cellular standards. Again, nothing 

in this architecture mentions the modem chip.

III. 3GPP Cellular Standard Requirements Specify that the “UE Shall”

21. Consistent with SA2’s architectural definition, 3GPP working groups that develop 

technical specifications set forth functional and performance requirements for these same 

functional domains, including thousands of “UE shall” requirements instead of the “modem chip

shall” or the like. 

22. For example, TS 25.331 defines the WCDMA Radio Resource Control (RRC) 

protocol and relevant behaviors for communication between the mobile device (UE) and the UMTS 

base stations (Universal Terrestrial Radio Access Network) (NodeB). ATIS, "3rd Generation 

Partnership Project; Technical Specification Group Radio Access Network; Radio Resource 

Control (RRC); Protocol specification (Release 14)," ATIS.3GPP.25.331V1450 (December 2017) 

(Exhibit 5); see also 3GPP, “3rd Generation Partnership Project; Technical Specification Group 

Radio Access Network; Radio Resource Control (RRC); Protocol specification (Release 14),” 

TS 25.331 v14.5.0, at 146 (December 2017), available at http://www.3gpp.org/DynaReport/25-

series.htm. The RRC provides various functions for establishing and maintaining connections 

between the UE and the NodeB/UTRAN. In this 3GPP specification, the specification states over 

1,500 times the “UE shall” meet some particular requirement. See id. Noticeably, it never once 

states that the “modem chip shall” meet any particular requirement. See id. This is because these 

specifications are intended to define—and are necessarily written from—the perspective of a 

complete end-user device. See id. 

23. TS 36.331 defines the LTE Radio Resource Control (RRC) protocol and relevant

ATIS.3GPP.36.331V1451 (January 2018) (Exhibit 6); see also 3GPP, “3rd Generation Partnership

TS 36.331 v14.5.1, at 62-63 (January 2018), available at http://www.3gpp.org/DynaReport/36-

between the UE and the eNodeB. See id. Over 350 times, this specification expressly sets forth 

“UE shall” requirements, while not including any “modem chip shall” requirements. See id. This 

is because the requirements of these specifications are intended to define—and are necessarily

used to manage the establishment of communication sessions and for maintaining continuous 

communications with mobile user equipment. ATIS, "3rd Generation Partnership Project;

http://www.3gpp.org/DynaReport/24-series.htm. Over 1,250 times, this specification expressly 

sets forth “UE shall” requirements, while not including any “modem chip shall” requirements. See 

id. Again, a modem chip by itself could not meet the requirements of these specifications directed 

towards UE behavior. See id. 

25. The following excerpts show a few examples of how the 3GPP standards 

specifications actually define the UE behavior, as opposed to cellular chip behavior.

26. For example, TS 25.331 (Exhibit 5) defines initial connection setup with a network. 

The excerpt below shows transfer procedures defined in relation to the UE, not a modem chip.

Id. at 146. As illustrated and defined, the required communications are between the UE and 

network, and not to any components within the UE.

27. TS 24.301 (Exhibit 7) defines UE behavior during security procedures to

authenticate a UE. Notably, this document concerns the USIM functional element mentioned 

previously, but makes no mention of a modem chip or other components within the UE. As shown 

in the excerpt below, all functionality is defined in relation to the UE and USIM functional 

elements.

IV. 3GPP UE Performance and Conformance Testing

29. 3GPP Cellular Standards specify performance and conformance testing of UEs to 

certify that UEs comply with the standards in order to facilitate smooth interoperation in cellular 

systems. This includes interoperation with infrastructure equipment and operation in a manner that

does not materially impact the operation and performance of other UEs. These testing 

specifications are at the device level (i.e., the entire handset), spelling out the way that an individual 

UE communicates with the network. Such standards-based procedures never deal with modem 

chips, and there are no 3GPP standards for performance or conformance testing requirements of 

modem chips.

30. After performance and functional objectives are set, substantial systems engineering 

efforts are required to develop standardized technical specifications meeting objectives that define 

the entire system. The technical specifications define the interfaces among the entities in the system 

(e.g., the air interface between the base station and UE), and specify how each UE must operate 

within the system to enable the system as a whole to meet these objectives that allow many users 

to simultaneously enjoy the benefits of the wireless technology.

31. The goal of conformance testing is to ensure a minimum level of system 

performance, and this is specified in terms of UE performance as a whole as opposed to the 

performance of its components. For the UE, conformance testing is categorized into three distinct 

areas: (1) Radio Frequency, (2) Radio Resource Management, and (3) Signaling  each of which is 

testing performed on a device level rather than a component (e.g., modem chip) level.

32. More specifically, 3GPP’s Radio Access Network Working Group 5 (“RAN 5”) has 

developed the following detailed conformance tests.1 None of these conformance tests are specific 

to a modem chip but instead focus on complete UEs. Indeed, a modem chip could not, by itself, 

meet any of these conformance tests.

 1 This table is excerpted from 3GPP, “3GPP Specifications for group: R5 (showing rapporteur),” 

available at http://www.3gpp.org/DynaReport/TSG-WG--R5.htm?Itemid=425 (last accessed 

September 13, 2018).
