Abstract

Various aspects provides an example method, an apparatus, and/or a computer readable medium for configuring common control resource set at an gNB, which may include configuring, at the gNB, a first type and a second type of common control resource set, and indicating, to a user equipment (UE), the first type and the second type of common control resource set based at least on the configuration. Additional aspects may include receiving, at the UE, configuration information of a first type and a second type of common control resource set from a gNB, and decoding, at the UE, the first type and the second type of common control resource set based at least on the configuration information.

1. A method of configuring common control resource set at a user equipment (UE), comprising:

receiving, at the UE, configuration information of a first type and a second type of common control resource set from a gNB; and

decoding, at the UE, the first type and the second type of common control resource set based at least on the configuration information.

2. The method of claim 1, wherein the first type of the common control resource set is committed control resources and the second type of the common control resource set is opportunistic common control resource set.

3. The method of claim 2, wherein receiving the configuration information comprises receiving the configuration information for at least one of the committed common control resource set at least partially common control resource set via a master information block (MIB), and the opportunistic common control resource set at least partially via RMSI.

4. The method of claim 3, wherein the first subset of slots and the second subset of slots are mutually exclusive.

5. The method of claim 2, further comprising always decoding the committed common control resource set, and opportunistically decoding the opportunistic common control resources only when the configuration information indicates there is control information for the UE.

6. The method of claim 2, further comprising decoding a message 2 of a random access channel procedure in both the committed common control resource set and the opportunistic common control resource set.

7. The method of claim 1, wherein the configuration information indicates that the first type and the second type of the common control resource set comprise sets of resources that at least partially overlap in time and frequency, and wherein the decoding further comprises decoding only one of the first type or the second type of the common control resource set within a slot based on the configuration information.

8. The method of claim 1, wherein the first type of common control resource set is a committed common control resource set and the second type of common control resource set is UE specific control resource set.

9. The method of claim 8, further comprising always decoding the committed common control resource set and opportunistically decoding the UE specific control resource set only in response to the configuration information indicating a grant corresponding to the UE specific control resource set.

10. The method of claim 8, wherein receiving the configuration information comprises receiving a first indication of the committed common control resource set via a master information block (MIB) and receiving a second indication of the UE specific control resource set via a radio resource control (RRC) signal.

11. The method of claim 8, further comprising decoding a four-step message 2 of a random access channel procedure via only the committed common control resource set, or decoding a two-step message 2 of the random access channel procedure via either the committed common control resource set or the UE specific control resource set.

12. The method of claim 8, wherein the configuration information identifies that continuous beamforming is configured for the UE specific control resource set, further comprising:

receiving a continuity indicator that identifies whether phase continuity is maintained over time for the UE specific control resource set; and

filtering or not filtering an estimated channel over time when performing channel estimation based on the continuity indicator.

13. The method of claim 8, wherein the configuration information identifies that physical resource block (PRB) beamforming is configured for the UE specific control resource set, further comprising:

filtering an estimated channel over time and frequency when performing channel estimation in response to the PRB beamforming.

14. The method of claim 8, wherein the configuration information identifies that the committed common resources and the UE specific control resource set is adjacently located and are subject to continuous beamforming, further comprising:

receiving a continuity indicator that identifies whether phase continuity is maintained between the committed common resources and the UE specific control resource set in a slot; and

performing a single channel estimation over both the committed common resources and the UE specific control resource set in the slot, or performing separate channel estimations on each of the committed common resources and the UE specific control resource set in the slot, based on the continuity indicator.

15. A user equipment (UE) for wireless communications, comprising:

a transceiver;

a memory;

a processor in communication with the transceiver and the memory and configured to;

receive configuration information of a first type and a second type of common control resource set from a gNB; and

decode the first type and the second type of common control resource set based at least on the configuration information.

16. The UE of claim 15, wherein the first type of the common control resource set is committed control resources and the second type of the common control resource set is opportunistic common control resource set.
