Abstract
Various communication systems may benefit from new slot formats to support dynamic allocation between SC and CP-OFDMA. In accordance with some embodiments, a method may include transmitting, by a network entity, at least one physical downlink slot containing at least one physical downlink shared channel (PDSCH) and at least one physical downlink control channel (PDCCH). The at least one PDCCH is associated with at least one subcarrier waveform without a cyclic prefix (CP). The at least one PDSCH is associated with at least one CP-orthogonal frequency division multiplexing (OFDM) or single carrier (SC) waveform.
Claims19
An apparatus, comprising:
- at least one memory comprising computer program code;
- at least one processor;
- wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus at least to:
- transmit at least one physical downlink slot containing at least one physical downlink shared channel (PDSCH) and at least one physical downlink control channel (PDCCH), wherein
- the at least one PDCCH is associated with at least one subcarrier waveform without a cyclic prefix (CP),
- the at least one PDSCH is associated with at least one CP-orthogonal frequency division multiplexing (OFDM) or single carrier (SC) waveform, and
- at least one additional guard interval separates the at least one PDCCH and the at least one PDSCH when the at least one PDSCH is associated with CP-OFDM waveform, wherein one or more of the at least one physical downlink slot containing at least one PDSCH associated with at least one SC waveform is aligned with the at least one PDSCH associated with CP-OFDM waveform through the guard interval.
An apparatus, comprising:
- at least one memory comprising computer program code;
- at least one processor;
- wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus at least to:
- transmit at least one slot containing at least one physical downlink shared channel (PDSCH), wherein the at least one PDSCH is associated with:
- at least one subcarrier waveform without a cyclic prefix (CP) and/or at least one CP-orthogonal frequency division multiplexing (OFDM),
- wherein one or more of the at least one slot containing at least one PDSCH associated with at least one subcarrier waveform without CP is aligned with the at least one PDSCH associated with CP-OFDM waveform through an additional guard interval.
An apparatus, comprising:
