Abstract

The present disclosure describes techniques and systems for user device-initiated bandwidth requests. In some aspects, a user device determines conditions related to communicating with a base station over a wireless connection. The user device selects, based on the determined conditions, a frequency bandwidth for communicating with the base station. The user device then transmits, to the base station, a request to communicate over the selected frequency bandwidth. In some implementations, the user device may receive, in response to transmitting the request, a resource grant allocating at least a portion of the selected frequency bandwidth for communicating over the wireless connection.

Claims

1. A method performed by a user device for user-device-initiated bandwidth requests, the method comprising:

establishing a wireless connection with a base station of a wireless network;

receiving a first resource grant from the base station, the first resource grant identifying a first frequency bandwidth for communicating with the base station over the wireless connection;

determining conditions related to communicating with the base station over the first frequency bandwidth identified in the first resource grant;

selecting, by the user device, a second frequency bandwidth for communicating with the base station, the selecting based on the determined conditions of the communication over the first frequency bandwidth;

transmitting, to the base station, a request to communicate with the base station over the second frequency bandwidth; and

receiving a second resource grant from the base station, the second resource grant allowing communication with the base station over the second frequency bandwidth or an alternate frequency bandwidth based on the second frequency bandwidth.

21. The method as recited in claim 1, wherein the second frequency bandwidth is a portion of a total bandwidth of the wireless network, the total bandwidth including a range of frequencies over which the wireless network can operate.

23. The method as recited in claim 1, wherein the conditions include wireless signals detected at the user device, the wireless signals not included in the wireless connection.

24. The method as recited in claim 1, wherein the conditions include:

a power status of the user device;

or

a thermal status of the user device.

25. The method as recited in claim 1, wherein the conditions include:

an amount of data to be transmitted to, or received from, the base station;

or

a type of data to be transmitted to, or received from, the base station.

26. The method as recited in claim 1, wherein the request includes a requested amount of communication resources within the second frequency bandwidth for communicating with the base station.

27. The method as recited in claim 26, wherein the requested amount of communication resources identifies a requested amount of uplink communication resources and a requested amount of downlink communication resources.

28. The method as recited in claim 1, wherein the user device transmits the request as a radio resource control message or as a medium access control message, the request transmitted over a currently allocated communication resource of the first resource grant, over a physical random access channel of the first resource grant, or over a supplemental uplink of the first resource grant.

29. The method as recited in claim 1, wherein the request includes a requested increasing or a decreasing of communication resources that are allocated to one or both of an uplink or a downlink in the first resource grant.

30. The method as recited in claim 1, wherein the request identifies:

a requested frequency hopping pattern comprising a change in a location of the second frequency bandwidth;

or

a requested schedule for changing elements of the second frequency bandwidth.

41. The method as recited in claim 1, further comprising communicating with the base station over the wireless connection using the second frequency bandwidth or the alternate frequency bandwidth.
