Abstract

Claims (43)

1 . A method of transmission of a user equipment (UE), comprising:

transmitting a first transmission, wherein the first transmission is used for synchronization and the first transmission occupies a bandwidth more than 11 resource blocks (RBs), wherein the first transmission comprises M RBs in frequency domain, where M is an integer greater than 11 RBs and M is related to subcarrier spacing and/or a reference bandwidth and/or a number of subcarriers in an RB, and wherein the first transmission is transmitted in a subset of the M RBs;

wherein the first transmission comprises m subset transmissions, where m is an integer greater than or equal to 1;

wherein at least one subset of the m subset transmissions is based on a first base sequence, and a length of the first base sequence is a prime value;

wherein the first transmission comprises at least one primary synchronization signal (PSS) and at least one physical broadcast channel (PBCH), and the at least one PSS and the at least one PBCH are fully or partially overlapped in time domain;

wherein the at least one PBCH comprises at least one symbol, and the at least one PSS is on the at least one symbol of the at least one PBCH.

2 . The method of claim 1 , wherein the reference bandwidth is 20 MHz.

3 . The method of claim 1 , wherein the M RBs comprise the RBs from the lowest RB to the highest RB of the first transmission in the frequency domain.

4 . The method of claim 1 ,

wherein the m subset transmissions are transmitted in different RBs of the M RBs in the frequency domain.

5 . The method of claim 4 ,

wherein the first base sequence has a length related to the values M and/or m and/or a number of subcarriers in an RB;

wherein the m subset transmissions are based on the same first base sequence;

wherein the m subset transmissions are applied with different phase rotations.

6 . The method of claim 1 , wherein the first transmission is transmitted in K symbols, where K is an integer greater than or equal to 1;

wherein the K symbols are consecutive in time domain.

7 . 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 transmit a first transmission, wherein the first transmission is used for synchronization and the first transmission occupies a bandwidth ore than 11 resource blocks (RBs), wherein the first transmission comprises M RBs in frequency domain, where M is an integer greater than 11 RBs and M is related to subcarrier spacing and/or a reference bandwidth and/or a number of subcarriers in an RB, and wherein the first transmission is transmitted in a subset of the M RBs;

wherein the first transmission comprises m subset transmissions, where m is an integer greater than or equal to 1;

wherein at least one subset of the m subset transmissions is based on a first base sequence, and a length of the first base sequence is a prime value;

wherein the first transmission comprises at least one primary synchronization signal (PSS) and at least one physical broadcast channel (PBCH), and the at least one PSS and the at least one PBCH are fully or partially overlapped in time domain;

wherein the at least one PBCH comprises at least one symbol, and the at least one PSS is on the at least one symbol of the at least one PBCH.

8 . The UE of claim 7 , wherein the reference bandwidth is 20 MHz.

9 . The UE of claim 7 , wherein the M RBs comprise the RBs from the lowest RB to the highest RB of the first transmission in the frequency domain.

10 . The UE of claim 7 ,

wherein the m subset transmissions are transmitted in different RBs of the M RBs in the frequency domain.

11 . The UE of claim 10 ,

wherein the first base sequence has a length related to the values M and/or m and/or a number of subcarriers in an RB;

wherein the m subset transmissions are based on the same first base sequence;

wherein the m subset transmissions are applied with different phase rotations.

12 . The UE of claim 7 , wherein the first transmission is transmitted in K symbols, where K is an integer greater than or equal to 1;

wherein the K symbols are consecutive in time domain.

13 . The UE of claim 7 , wherein the first transmission is on side-link.

14 . A chip, comprising:

a processor, configured to call and run a computer program stored in a memory, to cause a device in which the chip is installed to execute operation of:

transmitting a first transmission, wherein the first transmission is used for synchronization and the first transmission occupies a bandwidth more than 11 resource blocks (RBs), wherein the first transmission comprises M RBs in frequency domain, where M is an integer greater than 11 RBs and M is related to subcarrier spacing and/or a reference bandwidth and/or a number of subcarriers in an RB, and wherein the first transmission is transmitted in a subset of the M RBs;

wherein the first transmission comprises m subset transmissions, where m is an integer greater than or equal to 1;

wherein at least one subset of the m subset transmissions is based on a first base sequence, and a length of the first base sequence is a prime value;
