Embodiment Construction

[0036] Embodiments of the invention will now be described in more detail with reference to the accompanying drawings, in which identical or similar elements bear the same reference numerals.

[0037] Figure 4a -c shows a schematic diagram of a Physical Sidelink Feedback Channel (PSFCH) reporting window 400 . Such a PSFCH reporting window 400 . exist Figure 4a , a time-based mapping is shown where multiple PSSCHs for multiple time slots separated by subchannels can be acknowledged using common acknowledgments 402a, 402b, respectively.

[0038] exist Figure 4b , a frequency-based mapping is shown where acknowledgments 402a-c can be used to acknowledge multiple resources 406 or PSSCHs for different time slots.

[0039] exist Figure 4c , a hybrid-based mapping combining frequency-based and time-based mapping is shown, as shown in slot #1, where subchannel 2, SC2, is acknowledged by using acknowledgment 402a, and subchannel 1, SC1, is acknowledged by using acknowledgment 4...

Abstract

A device is configured to operate in a wireless communication network, the wireless communication network being operated to include a feedback channel providing feedback resources for acknowledging reception of a transmit message transmitted in the wireless communication network, the device acknowledges reception of a message, such as a control message of a PSSCH, by transmitting a first feedback message using a specific feedback resource; and waiting for acknowledgement transmission. The apparatus is configured to wait for reception of a second acknowledgement message sent using the same or another particular feedback resource. The device is configured to postpone or omit the transmission of the first feedback message to receive the second feedback message.

Description

Background technique [0001] Existing technology and problem description [0002] Fig. 1 is as shown in Fig. 1 (a) including the core network 102 and one or more radio access networks RAN 1 、RAN 2 …RAN N A schematic diagram of an example of a terrestrial wireless network 100 . Figure 1(b) is a graph that can include one or more base stations gNB 1 to gNB 5 Radio Access Network RAN n Schematic representation of an instance of , each base station serves a cell 106 1 to 106 5 Schematic representation of a specific area around a base station. A base station is provided to serve users within the cell. The term base station BS refers to a gNB in ​​5G networks, an eNB in ​​UMTS / LTE / LTE-A / LTE-A Pro, or simply a BS in other mobile communication standards. Users can be stationary or mobile. Wireless communication systems can also be accessed by mobile or fixed IoT devices connected to base stations or users. Mobile or IoT devices can include physical devices, ground-based veh...
