NR-SS unified operation mode in coordinated and uncoordinated bands
First Claim
1. A method of wireless communication, comprising:
- receiving, at a user equipment (UE), a reservation request (RRQ) transmitted by a next generation Node B (gNB); and
transmitting, by the UE in response to the RRQ, a reservation response signal (RRS),wherein the RRS carries a precoded sounding reference signal (SRS) modulated by an indication of interference estimated by UE.

Abstract
A medium reservation framework is disclosed for coexistence of coordinated and uncoordinated wireless networks in licensed spectrum and shared spectrum. The proposed medium reservation framework organically takes into account operating regimes with different numbers of Tx/Rx antennas per node, provides flexibility in trading off medium contention aggressiveness and power saving, leverages the inherent synchronization nature of NR, and covers both coordinated and uncoordinated operation scenarios. Various aspects of the medium reservation framework may be centered on one or more combinations of some basic building blocks, such as an operation grid, synchronization signals, and reservation messages, such as a reservation request signal (RRQ) and one or more a reservation response signals (RRS).

12. A method of wireless communication, comprising:
-
transmitting, by a next generation Node B (gNB) to a user equipment (UE), a reservation request (RRQ); detecting, by the gNB, a reservation response signal (RRS) transmitted by the UE in response to the RRQ, wherein the RRS includes a precoded sounding reference signal (SRS) modulated by an indication of interference estimated by UE; and employing the indication of interference to select, for wireless communication between the UE and the gNB, at least one of; a precoder; a rank;
ora modulation and coding scheme (MCS). - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A method of wireless communication, comprising:
-
transmitting, by a next generation Node B (gNB) to a user equipment (UE), a reservation request (RRQ); detecting, by the gNB, a reservation response signal (RRS) transmitted by the UE in response to the RRQ, wherein the RRS includes a precoded sounding reference signal (SRS) modulated by an indication of interference estimated by the UE, wherein the indication of interference communicates a rise in interference level, to wireless communications between the UE and a serving gNB thereof, that is attributable to one or more wireless transmissions by the gNB; and transmitting, by the gNB in response to the RRS, the wireless transmissions in a manner that avoids causing interference to the wireless communications that exceeds a predetermined interference level threshold. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)
