Abstract

Claims (39)

1 . A wireless communication method by a user equipment (UE), comprising:

determining a channel occupancy (CO) according to a first information, wherein the first information comprises a condition, and the CO comprises at least one of a UE initiated CO or a BS initiated CO, wherein the condition comprises an ordering, and the UE selects the UE initiated CO or the BS initiated CO according to the ordering; and

transmitting, to a base station (BS), an uplink (UL) transmission in the CO,

wherein the ordering comprises that the BS initiated CO has a higher priority than the UE initiated CO, and

wherein the UE obtains information about if a BS CO is initiated and when the BS CO is initiated, such that the UE can transmit the UL transmission in the BS initiated CO,

wherein the ordering comprises that the UE is allowed to transmit the UL transmission in the BS initiated CO, if the UL transmission is confined in the BS initiated CO in time domain and/or confined in the BS initiated CO in frequency domain,

wherein the UL transmission confined in the BS initiated CO in the time domain means that the UL transmission comprises a set of symbols in the time domain and the set of symbols are within the BS initiated CO, where the BS initiated CO starts from a beginning of a BS fixed frame period (FFP) period and ends at a maximum CO, where the maximum CO is determined according to a standard specification, and

the UL transmission confined in the BS initiated CO in the frequency domain means that the UL transmission comprises a set of frequency domain resources and the set of frequency domain resources is in one or more resource block (RB) sets of the BS initiated CO.

2 . The method of claim 1 , wherein the first information further comprises at least one of an indication, a pre-defined rule.

3 . The method of claim 2 , wherein the indication comprises that the UE is indicated to transmit, to the BS, the UL transmission in the UE initiated CO or the BS initiated CO.

4 . The method of claim 3 , wherein the indication is transmitted in a medium access control-control element (MAC-CE), a downlink control information (DCI), and/or a system information.

5 . The method of claim 3 , wherein when the UE receives the indication from the BS, the UE determines if the indication is valid.

6 . A wireless communication method by a base station (BS), comprising:

controlling a user equipment (UE) to determine a channel occupancy (CO) according to a first information, wherein the first information comprises a condition, and the CO comprises at least one of a UE initiated CO or a BS initiated CO, wherein the condition comprises an ordering, and the BS controls the UE to select the UE initiated CO or the BS initiated CO according to the ordering; and

receiving, from the UE, an uplink (UL) transmission in the CO,

wherein the ordering comprises that the BS initiated CO has a higher priority than the UE initiated CO, and

wherein the BS controls the UE to obtain information about if a BS CO is initiated and when the BS CO is initiated, such that the BS controls the UE to transmit the UL transmission in the BS initiated CO,

wherein the ordering comprises that the UE is allowed to transmit the UL transmission in the BS initiated CO, if the UL transmission is confined in the BS initiated CO in time domain and/or confined in the BS initiated CO in frequency domain,

wherein the UL transmission confined in the BS initiated CO in the time domain means that the UL transmission comprises a set of symbols in the time domain and the set of symbols are within the BS initiated CO, where the BS initiated CO starts from a beginning of a BS fixed frame period (FFP) period and ends at a maximum CO, where the maximum CO is determined according to a standard specification, and

wherein the UL transmission confined in the BS initiated CO in the frequency domain means that the UL transmission comprises a set of frequency domain resources and the set of frequency domain resources is in one or more resource block (RB) sets of the BS initiated CO.

7 . The method of claim 6 , wherein the first information further comprises at least one of an indication, a pre-defined rule.

8 . A base station, comprising:

a memory;

a transceiver; and

a processor coupled to the memory and the transceiver;

wherein the processor is configured to cooperate with the transceiver to implement the method of claim 6 .

9 . A user equipment (UE), comprising:

a memory;

a transceiver; and

a processor coupled to the memory and the transceiver;

wherein the processor is configured to cooperate with the transceiver to:

determine a channel occupancy (CO) according to a first information, wherein the first information comprises a condition, and the CO comprises at least one of a UE initiated CO or a BS initiated CO, wherein the condition comprises an ordering, and the UE selects the UE initiated CO or the BS initiated CO according to the ordering; and

transmit, to a base station (BS), an uplink (UL) transmission in the CO,

wherein the ordering comprises that the BS initiated CO has a higher priority than the UE initiated CO, and

wherein the UE obtains information about if a BS CO is initiated and when the BS CO is initiated, such that the UE can transmit the UL transmission in the BS initiated CO,

wherein the ordering comprises that the UE is allowed to transmit the UL transmission in the BS initiated CO, if the UL transmission is confined in the BS initiated CO in time domain and/or confined in the BS initiated CO in frequency domain,

wherein the UL transmission confined in the BS initiated CO in the time domain means that the UL transmission comprises a set of symbols in the time domain and the set of symbols are within the BS initiated CO, where the BS initiated CO starts from a beginning of a BS fixed frame period (FFP) period and ends at a maximum CO, where the maximum CO is determined according to a standard specification, and

wherein the UL transmission confined in the BS initiated CO in the frequency domain means that the UL transmission comprises a set of frequency domain resources and the set of frequency domain resources is in one or more resource block (RB) sets of the BS initiated CO.

10 . The UE of claim 9 , wherein the first information further comprises at least one of an indication, a pre-defined rule.
