`AMENDMENTS TO THE SPECIFICATION
`
`Please replace paragraph [0012] of the specification as filed on November19, 2019 with
`
`the following redlined paragraph:

`
`Figure 1 shows an example of a wireless communication network 100 in which the present
`
`disclosure may be applied. The wireless communication may be based on popular wireless
`
`standards such as IEEE 802.11. The wireless communication network 100 may comprise an
`
`Access Point (AP) 110 andthree stations (STA) 120, 130 and 140 associated with the AP 110.
`
`The AP 110 is equipped with a Primary Connectivity Radio (PCR) apparatus (hereinafter stated
`
`simply as "PCR") 112 whichis capable of transmitting and receiving wireless signals in the
`
`802.11 waveform (e.g. Orthogonal Frequency Division Multiplexing (OFDM)) as well as being
`
`capable of transmitting wireless signals in the Wake-up radio (WUR) waveform (e.g. On-Off
`
`Keying(QOK){90K). STAs 120, 130 and 140 are WUR capable STAsand are equipped with
`
`PCRs122, 132 and 142 respectively as well as Wake-up radio receivers (WURx) apparatus
`
`(hereinafter stated simply as "WURx") 124, 134 and 144 respectively. STAs 130 and 140 are
`
`capable of transmitting and receiving 802.11 signals and are also capable of receiving WUR
`
`signals. The PCRs 132 and 142 may only be turned on during active communication (PCR
`
`mode), while during period ofidle listening, the PCRs may be turned off and only the WURx
`
`134 and 144 may be operating (WUR mode). STA 120 however may be a custom made device
`
`that has all the functionalities of a WUR capable STA andin addition its PCR 122 also has the
`
`ability to transmit wireless signals in the Wake-up radio (WUR) waveform ((OOK). Or STA 120
`
`may simply be a device that possesses both the WUR AP functionalities as well as the WUR
`
`STA functionalities. When the AP 110 needs to communicate with STAsoperating in WUR
`
`mode,it may first transmit wake-up signal to instruct the STAsto transit to PCR mode by
`
`turning on the respective PCRsand switching off the WURx. Subsequently the AP and the STAs
`
`may perform communication over the PCR. Once the communication is over, the STAs may
`
`switch back to WUR mode by switching off the PCR and turning on the WURx.
`
`Please replace paragraph [0015] of the specification as filed on November19, 2019 with

`
`The WUP Payload 220 carries the actual wake-up signal and comprises a wake-up preamble
`
`222 and a WUR frame 230. The wake-up preamble 222 is used for automatic gain control
`
`(AGC), timing synchronization, packet detection etc., while the WUR frame 230 carries the
`
`control information. The WUR frame 230 may also be known as a WUR MACProtocol Data
`
`Unit (MPDU)and may be further composed of various sub-fields such as a MAC header240, a
`
`Frame check sequence (FCS) 252 as well as the optional Frame body 250. The MAC header 240
`
`may be further comprised of a Frame control field 242 that species the frame Type, frame length
`
`etc., an Address field 244242that may carry either one of the Transmitter Address, Receiver
`
`address or both. Other control information may be carried in the TD Control field 246 depending
`
`on the frame Type. For example in WURbeacon frames, the TD Control field 246 may carry a
`
`timestamp field, while in unicast WUR frames, the TD Control field 246 may carry a packet
`
`numberetc.
