Abstract

A device for handling channel access procedure includes a storage device and a processing circuit coupled to the storage device and configured to execute instructions stored in the storage device. The storage device is configured for storing the instructions of receiving an indication for an uplink transmission; determining at least one parameter of the device for a listen-before-talk procedure according to a capability of the device or a signaling from a base station; and performing the uplink transmission according to the indication.

First claim

a storage device, for storing instructions of:
receiving an indication for an uplink transmission;
determining at least one parameter of the device for a listen-before-talk procedure according to a capability of the device or a signaling from a base station; and
performing the uplink transmission according to the indication; and
a processing circuit, coupled to the storage device, configured to execute the instructions stored in the storage device.

2 . The device of claim 1 , wherein the signaling from the base station is comprised in the indication.

3 . The device of claim 1 , wherein the instructions further comprises reporting the capability of the device.

4 . The device of claim 1 , wherein the capability of the device comprises beamwidth of the device.

5 . The device of claim 4 , wherein the beamwidth of the device is wide beamwidth, narrow beamwidth, or variable beamwidth.

6 . The device of claim 1 , wherein the at least one parameter of the device comprises a threshold for energy detection during the listen-before-talk procedure.

7 . The device of claim 1 , wherein the at least one parameter of the device comprises a channel sensing time for the listen-before-talk procedure.

8 . The device of claim 1 , wherein the at least one parameter of the device comprises beamwidth of the device.

9 . A device for handling channel access procedure, comprising:
a storage device, for storing instructions of:
determining a first spatial domain filter for a first uplink transmission; and
determining a second spatial domain filter for a second uplink transmission; and
a processing circuit, coupled to the storage device, configured to execute the instructions stored in the storage device.

10 . The device of claim 9 , wherein a time interval between the first uplink transmission to be performed and the second uplink transmission to be performed is less than a duration standard.

11 . The device of claim 10 , wherein the time interval is predetermined or configured by a network.

12 . The device of claim 9 , wherein the instructions further comprises:
determining a third spatial domain filter for transmitting at least one of the first uplink transmission or the second uplink transmission.

13 . The device of claim 12 , wherein the instructions further comprises:
transmitting at least one of the first uplink transmission or the second uplink transmission by the third spatial domain filter.

14 . The device of claim 12 , wherein a third spatial domain filter is either the first spatial domain filter or the second spatial domain filter.

15 . The device of claim 9 , wherein the instructions further comprises:
performing a listen-before-talk procedure before transmitting at least one of the first uplink transmission or the second uplink transmission.

16 . The device of claim 9 , wherein the instructions further comprises:
determining a third spatial domain filter according to a priority rule between the first uplink transmission and the second uplink transmission.

17 . The device of claim 16 , wherein the third spatial domain filter equals the first spatial domain filter when a priority of the first uplink transmission is higher than a priority of the second uplink transmission, wherein the third spatial domain filter equals the second spatial domain filter when the priority of the second uplink transmission is higher than the priority of the first uplink transmission.

18 . The device of claim 9 , wherein the instructions further comprises determining a third spatial domain filter according to a chronological order between the first uplink transmission and the second uplink transmission.

19 . The device of claim 18 , wherein the third spatial domain filter equals the first spatial domain filter when the first uplink transmission is scheduled prior to the second uplink transmission, wherein the third spatial domain filter equals the second spatial domain filter when the second uplink transmission is scheduled prior to the first uplink transmission.

20 . The device of claim 9 , wherein a third spatial domain filter is determining according to a reference signal.

21 . The device of claim 20 , wherein the reference signal is a target reference signal for determining the first spatial domain filter of the first transmission and the second spatial domain filter of the second uplink transmission.

22 . The device of claim 9 , wherein the instructions further comprises:
transmitting at least one of the first uplink transmission and the second uplink transmission by a third spatial domain filter; and puncturing, dropping or postponing one of the first uplink transmission and the second uplink transmission.

23 . The device of claim 22 , wherein the second uplink transmission is dropped or punctured when a priority of the first uplink transmission is higher than a priority of the second uplink transmission, wherein the first uplink transmission is dropped or punctured when the priority of the second uplink transmission is higher than the priority of the first uplink transmission.

24 . The device of claim 22 , wherein one of the first uplink transmission and the second uplink transmission is postponed when coming after another one of the first uplink transmission and the second uplink transmission.
