Channel reservation for multi-user scheduling
First Claim
1. A method for wireless communication, comprising:
- measuring, by a user equipment (UE), a plurality of signal parameters for a plurality of frequency subbands in a shared radio frequency spectrum band received by the UE;
transmitting, by the UE, a quality message that includes the plurality of signal parameters measured by the UE; and
receiving, by the UE from a base station via the shared radio frequency spectrum band, a targeted preamble that indicates resources to be used by the UE to communicate data, wherein the targeted preamble comprises an instruction configured to silence an interference source during a transmission of data to the UE using the resources, the instruction comprising an indication of the interference source and the identified resources.

Abstract
Techniques are described herein to selectively protect some resources of a transmission opportunity, but not all resources of a transmission opportunity. A base station may schedule resources to be used to communicate data with a user equipment (UE). To indicate to potential interference sources, a silencing message may broadcast to other network entities. The silencing message may include an indication of resources to be protected for a transmission between the base station and the UE. The silencing message may indicate a subset of resources that is less than a set of all resources of a transmission opportunity. In some examples, the silencing message may indicate a subset of frequency subbands of the transmission opportunity. In response to the silencing message, potential interference sources may refrain from communicating data during the indicated subset of resources.

8. A method for wireless communication, comprising:
-
receiving, by a user equipment (UE), a resource request message from a base station; identifying, by the UE, a subset of resources of a transmission opportunity included in the resource request message to be used for receiving data from the base station; broadcasting, by the UE, a resource response message to a potential interference source indicating the subset of resources to be used for receiving data from the base station; and receiving, by the UE, data from the base station using the subset of resources. - View Dependent Claims (9, 10, 11, 12, 13)

14. A method for wireless communication, comprising:
-
receiving, by a network entity, a resource response message from a user equipment (UE); identifying a subset of frequency resources of a transmission opportunity included in the resource response message to be used by the UE to communicate data, wherein the subset of frequency resources is less than a set of all resources associated with the transmission opportunity; comparing the subset of frequency resources to scheduled resource to be used by the network entity to communicate data; and refraining, based at least in part on the subset of frequency resources overlapping with the scheduled resources, from transmitting data using the subset of frequency resources included in the resource response message. - View Dependent Claims (15, 16)

17. An apparatus for wireless communication, comprising:
-
a processor; memory in electronic communication with the processor; and instructions stored in the memory, wherein the instructions are executable by the processor to; receive, by a user equipment (UE), a resource request message from a base station; identify, by the UE, a subset of resources of a transmission opportunity included in the resource request message to be used for receiving data from the base station; broadcast, by the UE, a resource response message to a potential interference source indicating the subset of resources to be used for receiving data from the base station; and receive data from the base station using the subset of resources. - View Dependent Claims (18, 19, 20, 21, 22)
