Methods and apparatus for mitigating resource conflicts between ultra low latency (ULL) and legacy transmissions
First Claim
1. A method for wireless communication by a base station, comprising:
- determining a region of a subframe having overlapping resource allocations for a first device of a first type and a second device of a second type, wherein the first device of the first type has a capability to perform certain procedures with low latency relative to the second device of the second type that lacks the capability; and
modulating data from the region of the subframe for transmission to the first and the second devices, using a hierarchical modulation scheme, wherein the hierarchical modulation scheme comprises using a higher order modulation scheme for transmission of data from the region with the overlapping resource allocations, relative to one or more modulation schemes used for transmission of data in one or more regions of the subframe having one or more resource allocations exclusively for the first or the second device.

Abstract
Certain aspects of the present disclosure relate to methods and apparatus for mitigating resource conflicts between ultra low latency (ULL) and legacy transmissions. A base station may determine a region of a subframe having overlapping resource allocations for a first device of a first type (e.g., ULL device) and a second device of a second type (e.g., legacy device), wherein the first device of the first type has a capability to perform certain procedures with low latency relative to the second device of the second type that lacks the capability. The base station may modulate data from the region of the subframe for transmission to the first and the second devices, using a hierarchical modulation scheme.

11. A method for wireless communication by a first device of a first type, comprising:
-
receiving resource allocation of a second device of a second type, wherein the first device of the first type has a capability to perform certain procedures with low latency relative to the second device of the second type that lacks the capability; determining a region of a subframe having overlapping resource allocations for the first device and the second device, based on the received resource allocation of the second device; receiving data using resources allocated in the region of the subframe; and attempting to decode the data based on the determination, wherein the data was modulated using a hierarchical modulation scheme by using a higher order modulation scheme for modulating the data received in the region of the subframe having the overlapping resource allocations, relative to one or more modulation schemes used for modulating data from one or more regions of the subframe having one or more resource allocations exclusively for the first or the second device. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A method for wireless communication by a base station, comprising:
-
determining that a first transmission for a first device of a first type and a second transmission for a second device of a second type are mapped to a same resource element, wherein the first type of device has a capability to perform certain procedures with low latency relative to the second type of device that lacks the capability; and jointly adjusting soft symbol log likelihood ratio (LLR) strengths of the first and second transmissions to determine a third transmission to be transmitted using the resource element. - View Dependent Claims (20, 21, 22, 23)

24. A first device of a first type, comprising:
-
at least one processor configured to; receive resource allocation of a second device of a second type, wherein the first device of the first type has a capability to perform certain procedures with low latency relative to the second device of the second type that lacks the capability; determine a region of a subframe having overlapping resource allocations for the first device and the second device, based on the received resource allocation of the second device; receive data using resources allocated in the region of the subframe; and attempt to decode the data based on the determination, wherein the data was modulated using a hierarchical modulation scheme by using a higher order modulation scheme for modulating the data received in the region of the subframe having the overlapping resource allocations, relative to one or more modulation schemes used for modulating data from one or more regions of the subframe having one or more resource allocations exclusively for the first or the second device; and a memory coupled to the at least one processor. - View Dependent Claims (25, 26, 27)
