User equipments, base stations, and methods

3:

• A terminal device comprising:
• detection circuitry configured to obtain a value Q from a Master Information Block (MIB) in a Synchronization Signal/Physical Broadcast Channel (SS/PBCH) block in an SS/PBCH block candidate with time index Y, the time index Y being an index of the SS/PBCH block candidate among a first number of SS/PBCH block candidates in a half radio frame;
• and
• reception circuitry configured to monitor at least type-0 Physical Downlink Control Channel (PDCCH) common search space set which corresponds to either of the SS/PBCH block candidates with time indexes Z+j*Q, wherein
• each of the values j is any non-negative integer so that the Z+j*Q is smaller than a second number, and
• the value Z is determined by a remainder of the time index Y divided by the value Q, or determined by a remainder of a DMRS index for a PBCH in the SS/PBCH block divided by the value Q.

4:

• A base station device comprising:
• higher-layer processing circuitry configured to configure a value Q in a Master Information Block (MIB) in a Synchronization Signal/Physical Broadcast Channel (SS/PBCH) block in an SS/PBCH block candidate with time index Y, the time index Y being an index of the SS/PBCH block candidate among a first number of SS/PBCH block candidates in a half radio frame;
• and
• transmission circuitry configured to transmit the MIB, and transmit a Physical Downlink Control Channel (PDCCH) in type-0 PDCCH common search space set which corresponds to either of the SS/PBCH block candidates with time indexes Z+j*Q, wherein
• each of the values j is any non-negative integer so that the Z+j*Q is smaller than a second number, and
• the value Z is determined by a remainder of the time index Y divided by the value Q, or determined by a remainder of a DMRS index for a PBCH in the SS/PBCH block divided by the value Q.

• and
• monitoring at least type-0 Physical Downlink Control Channel (PDCCH) common search space set which corresponds to either of the SS/PBCH block candidates with time indexes Z+j*Q, wherein
• each of the values j is non-negative integer so that the Z+j*Q is smaller than a second number, and
• the value Z is determined by a remainder of the time index Y divided by the value Q, or determined by a remainder of a DMRS index for a PBCH in the SS/PBCH block divided by the value Q.
