Abstract

Apparatuses, methods and storage media associated with components and implementations of wireless communication networks, and/or portions thereof, are disclosed herein. In embodiments, an apparatus for a next generation NodeB (gNB) may include processing circuitry to determine a number of resource element groups (REGs) to be included in a resource element group bundle (REGB) for a new radio physical downlink control channel (NR-PDCCH), and generate a signal that indicates the number of the REGs. The gNB may further include encoding circuitry, coupled with the processing circuitry, to encode the signal for transmission to a user equipment (UE). Other embodiments may be disclosed throughout.

First claim

The invention claimed is:

1. An access node (AN), comprising:
first circuitry to:
configure a new radio physical downlink control channel (NR-PDCCH) to include a plurality of resource element group bundles (REGBs), the plurality of REGBs having a same number of resource element groups (REGs) as one another,
wherein REGs within at least one REGB from among the plurality of REGBs are assigned to a same number as one another,
wherein the plurality of REGBs are cyclically numbered based upon a number of control channel elements (CCEs) in accordance with a bundling direction, and
generate a signal that indicates a number of the REGs within the at least one REGB, the number of CCEs, and the bundling direction; and

second circuitry, coupled with the first circuitry, to encode the signal for transmission to a user equipment (UE).

2. The AN of claim 1 , wherein the bundling direction comprises: a time-first order or a frequency-first order.

3. The AN of claim 1 , wherein the first circuitry is further to:
determine whether a search space (SS) is to be configured in a localized manner, a distributed manner, or a hierarchical manner, and
wherein the signal further indicates that the SS is to be configured in the localized manner, the distributed manner, or the hierarchical manner based on the determination.

4. The AN of claim 3 , wherein the first circuitry is further to:
determine that the SS is to be configured in the hierarchical manner,
determine a hierarchical SS structure for the UE based on channel conditions associated with the UE or channel state information associated with the UE, and
wherein the signal further indicates the hierarchical SS structure.

5. The AN of claim 4 , wherein the hierarchical SS structure indicates whether the UE is to aggregate blind decoding (BD) candidates of the SS in a time domain or in a frequency domain.

6. The AN of claim 1 , wherein the second circuitry is further to transmit the signal via higher layer signaling.

7. The AN of claim 1 , wherein the second circuitry is further to transmit the signal via radio resource control (RRC) signaling.

8. The AN of claim 1 , wherein the second circuitry comprises a baseband processor or encoding circuitry.

9. The AN of claim 1 , wherein at least one REG from among the number of REGs comprises a plurality of consecutive resource elements (REs) in a frequency domain of an orthogonal frequency division multiplexing (OFDM) symbol.

10. A user equipment (UE), comprising:
first circuitry to receive a signal from an access node (AN) that indicates a configuration of a search space (SS) having a plurality of resource element group bundles (REGBs), resource element group bundles (REGBs), the plurality of REGBs having a same number of resource element groups (REGs) as one another, and the signal the signal including a number of REGs within at least one REGB from among the plurality of REGBs, a number of control channel elements (CCEs), and a bundling direction; and
second circuitry to:
assign REGs within the at least one REGB from among the plurality of REGBs to a same number as one another, and
cyclically number the plurality of REGBs to the number of CCEs in accordance with the bundling direction to configure the SS.

11. The UE of claim 10 , wherein the second circuitry is further to:
identify an indication of whether the SS is to be configured in a localized manner, a distributed manner, or a hierarchical manner, the indication received from the AN, and
further configure the SS based on the indication.

12. The UE of claim 11 , wherein the indication identifies the SS is to be configured in the hierarchical manner, and
wherein the second circuitry is further to:
identify an indication of a hierarchical SS structure for the UE, and

further configure the SS based on the hierarchical SS structure.

13. The UE of claim 10 , wherein the bundling direction comprises a time-first order or a frequency-first order.

14. The UE of claim 10 , wherein the first circuitry is further to receive the signal via higher layer signaling.

15. The UE of claim 10 , wherein the first circuitry is further to receive the signal via radio resource control (RRC) signaling.

16. The UE of claim 10 , wherein at least one REG from among the number of REGs comprises a plurality of consecutive resource elements (REs) in a frequency domain of an orthogonal frequency division multiplexing (OFDM) symbol.

17. A method for configuring a new radio physical downlink control channel (NR-PDCCH), the method comprising:
configuring, by an access node (AN), the NR-PDCCH to include a plurality of resource element group bundles (REGBs), the plurality of REGBs having a same number of resource element groups (REGs) as one another,
wherein REGS within the at least one REGB from among the plurality of REGBs are assigned to a same number as one another, and
wherein the plurality of REGBs are cyclically based upon a number of control channel elements (CCEs) in accordance with a bundling direction;

18. The method of claim 17 , wherein the bundling direction comprises: a time-first order or a frequency-first order.

19. The method of claim 17 , further comprising transmitting, by the AN, the signal via higher layer signaling.

20. The method of claim 17 , further comprising transmitting, by the AN, the signal via radio resource control (RRC) signaling.
