Claim
1. A method for wireless communications by a user equipment (UE), comprising:', 'determining a first set of frequency resources and time resources for a first search space with which control channel transmissions for a first service type are configured to be communicated, wherein the frequency resources of the first set span a first region that is a narrowband region within wider system bandwidth;', 'determining a second set of frequency resources and time resources for a second search space with which control channel transmissions for a second service type are configured to be communicated, wherein the frequency resources of the second set span a second region of the system bandwidth; and', 'monitoring for the control channel transmissions, based on the first search space and the second search space.
2. The method of claim 1,', 'wherein the first service type includes enhanced mobile broadband (eMBB) services; and', 'wherein the second service type includes ultra reliable low latency communications (URLLC) services.
3. The method of claim 1, wherein the UE receives rate matched reference signals that are rate matched differently based on transmitting control channels in either the first search space or the second search space.
4. The method of claim 1, wherein at least one of a different downlink control information (DCI) formats or a different DCI sizes are used in the first search space and the second search space.
5. The method of claim 1, wherein the monitoring comprises:', 'monitoring for a first number of decoding candidates in the first search space; and monitoring for a second number of decoding candidates in the second search space, wherein the first number is different than the second number.
6. The method of claim 1, wherein the UE receives control channel transmissions sent in the first search space using different transmission schemes than the second search spaces.
7. The method of claim 1, wherein the UE receives control channel transmissions in both the first search space and the second search space in a same time instance.
8. The method of claim 7, wherein the UE determines that a control channel transmission sent in the second search space has precedence over a control channel transmission sent in the first search space when both are sent in the same time instance.
9. The method of claim 1, further comprising receiving signaling indicating whether reference signals (RS) are shared for the first search space and the second search space
10. The method of claim 1, further comprising receiving, in a grant sent in one of the first search space and the second search space at a first time instance, an indication of whether a transmission in the other of the first search space and the second search space is scheduled for the same or a different time instance
11. The method of claim 1, further comprising receiving signaling indicating a subset of locations within at least one of the first search space and the second search space to be monitored during a same or subsequent subframe
12. The method of claim 10, wherein the indication is signaled via a cross-symbol indicator
13. The method of claim 1, further comprising:', 'receiving a control channel transmission in a first bandwidth of a time slot of the first search space; and', 'monitoring, in the same time slot, for a data channel transmission in a second bandwidth indicated in the control channel transmission
14. The method of claim 1, further comprising identifying at least one of reserved time or frequency resources within the system bandwidth that are not specified for the first or second service type
15. The method of claim 14, wherein the reserved time or frequency resources comprise at least one of:', 'one or more guard bands in a symbol or set of symbols; or
one or more guard periods between on or more symbols or portions of symbols
16. A method for wireless communications by a base station, comprising:', 'determining a first set of frequency resources and time resources for a first search space with which control channel transmissions for a first service type are configured to be communicated, wherein the frequency resources of the first set span a first region that is a narrowband region within wider system bandwidth;', 'determining a second set of frequency resources and time resources for a second search space with which control channel transmissions for a second service type are configured to be communicated, wherein the frequency resources of the second set span a second region of the system bandwidth; and', 'transmitting the control channel transmissions, based on the first search space and the second search space
17. The method of claim 16,', 'wherein the first service type includes enhanced mobile broadband (eMBB) services; and', 'wherein the second service type includes ultra reliable low latency communications (URLLC) services
18. The method of claim 16, wherein rate matching is performed differently for reference signals when transmitting control channels in the first search space and the second search space
19. The method of claim 16, wherein at least one of a different downlink control information (DCI) formats or a different DCI sizes are used in the first search space and the second search space.
20. The method of claim 16, wherein the sending comprises:', 'selecting from a first number of decoding candidates in the first search space; and selecting from a second number of decoding candidates in the second search space, wherein the first number is different than the second number.
21. The method of claim 16, further comprising providing signaling indicating whether reference signals (RS) are shared for the first search space and the second search space.
22. The method of claim 16, further comprising identifying at least one of reserved time or frequency resources within the system bandwidth that are not specified for the first or second service type.
23. An apparatus for wireless communications by a user equipment, comprising:', 'means for determining a first set of frequency resources and time resources for a first search space with which control channel transmissions for a first service type are configured to be communicated, wherein the frequency resources of the first set span a first region that is a narrowband region within wider system bandwidth;', 'means for determining a second set of frequency resources and time resources for a second search space with which control channel transmissions for a second service type are configured to be communicated, wherein the frequency resources of the second set span a second region of the system bandwidth; and', 'means for monitoring for the control channel transmissions, based on the first search space and the second search space.
24. The apparatus of claim 23,', 'wherein the first service type includes enhanced mobile broadband (eMBB) services; and', 'wherein the second service type includes ultra reliable low latency communications (URLLC) services.
25. The apparatus of claim 23, wherein the UE receives rate matched reference signals that are rate matched differently based on transmitting control channels in either the first search space or the second search space.
26. The apparatus of claim 23, wherein at least one of a different downlink control information (DCI) formats or a different DCI sizes are used in the first search space and the second search space.
27. The apparatus of claim 23, wherein the means for monitoring comprises:', 'means for monitoring for a first number of decoding candidates in the first search space; and means for monitoring for a second number of decoding candidates in the second search space, wherein the first number is different than the second number.
28. The apparatus of claim 23, further comprising means for receiving signaling indicating whether reference signals (RS) are shared for the first search space and the second search space.
29. An apparatus for wireless communications by a base station, comprising:', 'means for determining a first set of frequency resources and time resources for a first search space with which control channel transmissions for a first service type are configured to be communicated, wherein the frequency resources of the first set span a first region that is a narrowband region within wider system bandwidth;', 'means for determining a second set of frequency resources and time resources for a second search space with which control channel transmissions for a second service type are configured to be communicated, wherein the frequency resources of the second set span a second region of the system bandwidth; and', 'means for transmitting the control channel transmissions, based on the first search space and the second search space.
