Abstract

Claims (53)

process, within the first period of time and before receiving one of the at least two SSBs, a Physical Downlink Control Channel (PDCCH) transmission over a first number of symbols of a first aggregated slot that comprises at least one slot, the first number of symbols being equal to or greater than four, the PDCCH transmission to schedule data in the first aggregated slot; and

generate, within the first period of time and after receiving the one of the at least two SSBs, a Physical Uplink Control Channel (PUCCH) transmission over a second number of symbols of the first aggregated slot, the second number of symbols being equal to or greater than two,

wherein the PDCCH and PUCCH transmissions have 480 or 960 kHz subcarrier spacing; and

interface ciruitry to communicatively coupled the processing circuitry to a component of a device.

2. The baseband processor of claim 1 , wherein the first number of symbols is a sequence of consecutive symbols, and wherein the second number of symbols is a sequence of consecutive symbols.

3. The baseband processor of claim 1 , wherein the at least two SSBs are transmitted with an SSB pattern that includes a gap between adjacent SSBs, and

wherein the processing circuitry is further configured to:

generate the PUCCH transmission within a time period that corresponds to the gap between adjacent SSBs; and

process a second PDCCH transmission within a time period that corresponds to the gap between adjacent SSBs.

4. The baseband processor of claim 1 , wherein the PDCCH transmission is to schedule data in at least two slots of the first aggregated slot.

5. The baseband processor of claim 1 , wherein a first of the at least two SSBs begins at a first time offset from a start of the first aggregated slot, and

wherein a second of the at least two SSBs begins at a second time offset from a start of a second aggregated slot that immediately follows the first aggregated slot, and

wherein the first time offset is equal to the second time offset.

6. One or more non-transitory computer-readable media having instructions that are to be executed to cause processing circuitry to:

generate at least two Synchronization Signal Blocks (SSBs) over a first period of time, the at least two SSBs having 120 kHz or 240 kHz subcarrier spacing;

generate, within the first period of time and before transmitting one of the at least two SSBs, a Physical Downlink Control Channel (PDCCH) transmission over a first number of symbols of a first aggregated slot that comprises at least one slot, the first number of symbols being equal to or greater than four, the PDCCH transmission to schedule data in the first aggregated slot; and

process within the first period of time and after transmitting the one of the at least two SSBs, a Physical Uplink Control Channel (PUCCH) transmission over a second number of symbols of the first aggregated slot, the second number of symbols being equal to or greater than two,

wherein the PDCCH and PUCCH transmissions have 480 or 960 kHz subcarrier spacing.
