Abstract

Claims (56)

1 . A User Equipment (UE) configured to operate in a wireless system, the device comprising:

at least one transceiver;

at least one processor; and

at least one computer memory operably connectable to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:

receiving a capability enquiry message from a serving cell;

transmitting a capability information to the serving cell, based on that the capability enquiry message is received; and

transmitting an uplink signal based on first Component Carrier (CC) within a New Radio (NR) TDD operating band; and

receiving a downlink signal based on second CC within NR TDD operating band,

wherein a value of Maximum Sensitivity Degradation (MSD) is applied to a reference sensitivity used for the receiving of the downlink signal,

wherein the capability information includes that the UE supports simultaneous Reception (Rx) and Transmission (Tx) (Rx/Tx) operation for intra-band,

wherein first CC and second CC within the NR TDD operating band are configured for the simultaneous Rx/Tx operation for intra-band, and

wherein the value of MSD for the simultaneous Rx/Tx operation is based on a frequency gap between the first CC and the second CC.

2 . The UE of claim 1 ,

wherein the NR TDD operating band is NR operating band n77, and

wherein the NR operating band n77 includes frequency range of 3300 MHz to 4200 MHz for an uplink operating band and downlink operating band.

3 . The UE of claim 1 ,

wherein the reception of the downlink signal and the transmission of the uplink signal is simultaneously performed within the NR TDD operating band, based on that the simultaneous Rx/Tx operation for intra-band is supported by the UE.

4 . The UE of claim 1 ,

wherein the value of MSD is equal to or less than 11.6 dB, based on that the frequency gap is equal to 153 MHz.

5 . The UE of claim 1 ,

wherein the value of MSD is equal to or less than 3.2 dB, based on that the frequency gap is equal to 500 MHz.

6 . The UE of claim 1 ,

wherein the frequency gap is defined based on a difference between a lower edge of the second CC and upper edge of the first CC, and

wherein the second CC is based on higher frequency than the first CC.

7 . A method for performing communication, the method performed by a User Equipment (UE) and comprising:

receiving a capability enquiry message from a serving cell;

transmitting a capability information to the serving cell, based on that the capability enquiry message is received; and

transmitting an uplink signal based on first Component Carrier (CC) within a New Radio (NR) TDD operating band; and

receiving a downlink signal based on second CC within NR TDD operating band,

wherein a value of Maximum Sensitivity Degradation (MSD) is applied to a reference sensitivity used for the receiving of the downlink signal,

wherein the capability information includes that the UE supports simultaneous Reception (Rx) and Transmission (Tx) (Rx/Tx) operation for intra-band,

wherein first CC and second CC within the NR TDD operating band are configured for the simultaneous Rx/Tx operation for intra-band, and

wherein the value of MSD for the simultaneous Rx/Tx operation is based on a frequency gap between the first CC and the second CC.

8 . The method of claim 7 ,

wherein the NR TDD operating band is NR operating band n77, and

wherein the NR operating band n77 includes frequency range of 3300 MHz to 4200 MHz for an uplink operating band and downlink operating band.

9 . The method of claim 7 ,

wherein the reception of the downlink signal and the transmission of the uplink signal is simultaneously performed within the NR TDD operating band, based on that the simultaneous Rx/Tx operation for intra-band is supported by the UE.

10 . The method of claim 7 ,

wherein the value of MSD is equal to or less than 11.6 dB, based on that the frequency gap is equal to 153 MHz.

11 . The method of claim 7 ,

wherein the value of MSD is equal to or less than 3.2 dB, based on that the frequency gap is equal to 500 MHz.

12 . The method of claim 7 ,

wherein the frequency gap is defined based on a difference between a lower edge of the second CC and upper edge of the first CC, and

wherein the second CC is based on higher frequency than the first CC.

13 . A device operating in a wireless communication system, the wireless device comprising:

at least processor; and

at least one computer memory operably connectable to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:

obtaining a capability enquiry message;

generating a capability information, based on that the capability enquiry message is obtained; and

generating an uplink signal based on first Component Carrier (CC) within a New Radio (NR) TDD operating band; and

obtaining a downlink signal based on second CC within NR TDD operating band,

wherein a value of Maximum Sensitivity Degradation (MSD) is applied to a reference sensitivity used for the receiving of the downlink signal,

wherein the capability information includes that the device supports simultaneous Reception (Rx) and Transmission (Tx) (Rx/Tx) operation for intra-band,

wherein first CC and second CC within the NR TDD operating band are configured for the simultaneous Rx/Tx operation for intra-band, and

wherein the value of MSD for the simultaneous Rx/Tx operation is based on a frequency gap between the first CC and the second CC.
