Abstract

Techniques are described for backhaul operations in a millimeter wave wireless communication system. A first base station of the millimeter wave wireless communication system identifies an access demand and one or more access communication parameters associated with the first base station. The first base station sends information to a second base station indicative of the access demand and the one or more access communication parameters, and determines one or more backhaul communication parameters associated with the second base station of the millimeter wave wireless communication system. The first base station establishes a wireless backhaul link with the second base station via the millimeter wave wireless communication system. The first base station partitions resources between an access link with one or more user equipments and the established wireless backhaul link based at least in part on the access demand, the one or more access communication parameters, or the backhaul communication parameters.

First claim

What is claimed is:

1 . A method for wireless communication in a millimeter wave wireless communication system, comprising:
identifying, by a first base station of the millimeter wave wireless communication system, an access demand and one or more access communication parameters associated with the first base station of the millimeter wave wireless communication system, the one or more access communication parameters based at least in part on the access demand; sending information to a second base station indicative of the access demand and the one or more access communication parameters; determining, by the first base station, one or more backhaul communication parameters associated with the second base station of the millimeter wave wireless communication system based at least in part on the access demand; establishing, by the first base station, a wireless backhaul link with the second base station via the millimeter wave wireless communication system, the wireless backhaul link based at least in part on the access demand, the one or more access communication parameters, or the one or more backhaul communication parameters; and partitioning, by the first base station, resources between an access link with one or more user equipments (UEs) and the established wireless backhaul link based at least in part on the access demand, the one or more access communication parameters, or the one or more backhaul communication parameters.

2 . The method of claim 1 , further comprising:
identifying a network entity in communication with the first base station and the second base station; and receiving information from the network entity indicative of at least one of the one or more backhaul communication parameters.

3 . The method of claim 2 , further comprising:
sending information to the network entity indicative of the access demand, wherein the information received from the network entity indicative of at least one of the one or more backhaul communication parameters is based at least in part on the access demand.

4 . The method of claim 2 , further comprising:
receiving information from the network entity indicative of at least one of the one or more backhaul communication parameters on a periodic schedule.

5 . The method of claim 2 , wherein the network entity is connected to the first base station and the second base station via a wired communication link.

6 . The method of claim 2 , wherein the network entity is connected to the first base station and the second base station via a wireless communication link associated with a third base station of the millimeter wave wireless communication system.

7 . The method of claim 1 , wherein the one or more access communication parameters comprises at least one of a timeslot associated with a wireless access link, or a time frequency block associated with the wireless access link, or combinations thereof.

8 . The method of claim 1 , wherein the one or more backhaul communication parameters comprises at least one of a timeslot associated with the wireless backhaul link, or a time frequency block associated with the wireless backhaul link, or a beamforming parameter associated with the wireless backhaul link, or a modulation-and-coding scheme (MCS) associated with the wireless backhaul link, or combinations thereof.

9 . The method of claim 1 , wherein the partitioning is based on optimization techniques.

10 . The method of claim 1 , further comprising:
sending information indicative of the access demand to the second base station wirelessly via the millimeter wave wireless communication system; and receiving information from the second base station indicative of at least one of the one or more backhaul communication parameters.

11 . The method of claim 1 , further comprising:
sending information indicative of the access demand to a third base station of the millimeter wave wireless communication system; and receiving, from the third base station, information indicative of at least one of the one or more backhaul communication parameters associated with the second base station.

12 . The method of claim 1 , further comprising:
receiving a first message from the second base station conveying an indication of a second base station access demand; and sending a second message to the second base station conveying an indication of one or more communication parameters associated with the first base station.

13 . The method of claim 12 , further comprising:
establishing a wireless backhaul link with the second base station based at least in part on the one or more communication parameters associated with the first base station.

14 . The method of claim 1 , further comprising:
identifying initial signaling schemes between the first base station and the second base station, the initial signaling schemes comprising a sequence of transmit, receive (TX, RX) and receive, transmit (RX, TX) pairs in consecutive frames.

15 . The method of claim 14 , wherein the (TX, RX) pair represents a time slot for transmitting information associated with a state of the first base station followed by a slot for receiving information from additional base stations.

16 . The method of claim 14 , further comprising:
creating pattern tables of one or more schedules associated with the initial signaling schemes.

17 . The method of claim 16 , further comprising:
using the pattern tables to determine a schedule to achieve low latency.

18 . A first base station for wireless communication, comprising:
a processor; memory in electronic communication with the processor; and instructions stored in the memory, the instructions being executable by the processor to: identify an access demand and one or more access communication parameters associated with the first base station of a millimeter wave wireless communication system, the one or more access communication parameters based at least in part on the access demand; send information to a second base station indicative of the access demand and the one or more access communication parameters; determine one or more backhaul communication parameters associated with the second base station of the millimeter wave wireless communication system based at least in part on the access demand; establish a wireless backhaul link with the second base station via the millimeter wave wireless communication system, the wireless backhaul link based at least in part on the access demand, the one or more access communication parameters, or the one or more backhaul communication parameters; and partition resources between an access link with one or more user equipments (UEs) and the established wireless backhaul link based at least in part on the access demand, the one or more access communication parameters, or the one or more backhaul communication parameters.

19 . The first base station of claim 18 , further comprising instructions executable by the processor to:
identify a network entity in communication with the first base station and the second base station; and receive information from the network entity indicative of at least one of the one or more backhaul communication parameters.

20 . The first base station of claim 19 , further comprising instructions executable by the processor to:
send information to the network entity indicative of the access demand, wherein the information received from the network entity indicative of at least one of the one or more backhaul communication parameters is based at
