Accused Instrumentalities: cellular base stations and mobile devices that support 3GPP carrier aggregation, and all versions and variations thereof since 

the issuance of the asserted patent.

Claim 1 Public Documentation

[1pre] A method of transmitting information in a wireless communication 

channel comprising:

To the extent the preamble is found to be limiting, the Accused Instrumentalities perform a method of transmitting information in a 

wireless communication channel.

For example, Samsung’s Accused Instrumentalities support 3GPP carrier aggregation technologies for transmitting uplink and/or 

downlink information over LTE and/or NR wireless channels. At least the Galaxy S23 series of Accused Instrumentalities supports 

5G aggregation. Furthermore, numerous Samsung Galaxy models support LTE carrier aggregation.

See, e.g.:

5.4 Carrier aggregation

5.4.1 Carrier aggregation

In Carrier Aggregation (CA), two or more Component Carriers (CCs) are aggregated. A UE may simultaneously receive or transmit 

on one or multiple CCs depending on its capabilities:

- A UE with single timing advance capability for CA can simultaneously receive and/or transmit on multiple CCs corresponding 

to multiple serving cells sharing the same timing advance (multiple serving cells grouped in one TAG);

- A UE with multiple timing advance capability for CA can simultaneously receive and/or transmit on multiple CCs corresponding to multiple serving cells with different timing advances (multiple serving cells grouped in multiple TAGs). NG-RAN 

ensures that each TAG contains at least one serving cell;

- A non-CA capable UE can receive on a single CC and transmit on a single CC corresponding to one serving cell only (one 

serving cell in one TAG).

CA is supported for both contiguous and non-contiguous CCs. When CA is deployed frame timing and SFN are aligned across cells 

that can be aggregated, or an offset in multiples of slots between the PCell/PSCell and an SCell is configured to the UE. The maximum 

number of configured CCs for a UE is 16 for DL and 16 for UL.

6.7 Carrier Aggregation

In case of CA, the multi-carrier nature of the physical layer is only exposed to the MAC layer for which one HARQ entity is required 

per serving cell as depicted on Figures 6.7-1 and 6.7-2 below:

- In both uplink and downlink, there is one independent hybrid-ARQ entity per serving cell and one transport block is generated 

per assignment/grant per serving cell in the absence of spatial multiplexing. Each transport block and its potential HARQ 

retransmissions are mapped to a single serving cell.

Claim 1 Public Documentation

[1a] transmitting first information across 

a first frequency range using a wireless 

transmitter, the first frequency range having a first center frequency, a first highest 

frequency, and a first lowest frequency; 

and

The Accused Instrumentalities perform a method including transmitting first information across a first frequency range using a wireless transmitter, the first frequency range having a first center frequency, a first highest frequency, and a first lowest frequency.

For example, the Accused Instrumentalities transmit uplink information on a first component carrier with a frequency range with a 

first center frequency (labeled FC,low in the excerpt from 3GPP TS 38.101 V17.9.0 below), first highest frequency (highlighted in red 

below), and first lowest frequency (highlighted in blue below). This applies in the cases of intra-band contiguous, intra-band noncontiguous, and inter-band CA.

[1b] simultaneously transmitting second 

information across a second frequency 

range using the same wireless transmitter, 

the second frequency range having a second center frequency greater than the first 

center frequency, a second highest frequency, and a second lowest frequency.

The Accused Instrumentalities perform a method including simultaneously transmitting second information across a second frequency 

range using the same wireless transmitter, the second frequency range having a second center frequency greater than the first center 

frequency, a second highest frequency, and a second lowest frequency.

For example, the Accused Instrumentalities transmit uplink information on a second component carrier with a frequency range with 

a second center frequency (labeled FC,high in the excerpt from 3GPP TS 38.101 V17.9.0 below), second highest frequency (highlighted 

in red below), and second lowest frequency (highlighted in blue below). This applies in the cases of intra-band contiguous, intra-band 

non-contiguous, and inter-band CA. The transmission is performed simultaneously using the same wireless transmitter, as set out in 

section 5.4 of 3GPP TS 38.300 V17.4.0.
