Method implemented in a user equipment
First Claim
1. A method implemented in a user equipment UE for single carrier frequency division multiple access SC-FDMA within a wireless system comprising:
- receiving, at the UE, an assignment of a first type of uplink scheduling request resource comprising a first plurality of subcarriers of the wireless system;
detecting, at the UE, a change in activity of the UE, wherein the change in activity is related to one or more applications resident on the UE;
determining, at the UE and in response to the detected change in activity, that a change in uplink scheduling request resource type should be made;
upon determining that a change in scheduling request resource type should be made, selecting, at the UE, a second type of uplink scheduling request resource comprising a second plurality of subcarriers for transmission of scheduling requests, wherein one of the first type or the second type is an unscheduled shared SC-FDMA resource assigned to a plurality of UEs of the wireless system and an other of the first type or the second type is a dedicated SC-FDMA resource assigned to only the UE, wherein the second plurality of subcarriers are located within a same system bandwidth as the first plurality of subcarriers; and
transmitting a signal comprising an encoded user ID on subcarriers used for the unscheduled shared SC-FDMA resource.

Abstract
In some implementations, a method implemented in a user equipment UE for single carrier frequency division multiple access SC-FDMA within a wireless system includes receiving an assignment of a plurality of uplink scheduling request resources and comprising a plurality of SC-FDMA subcarriers of the wireless system. One of the plurality of uplink scheduling request resources is selected for transmission of scheduling requests. It is determined that a change in uplink scheduling request resource should be made. Upon determining that a change in scheduling request resource should be made, another of the assigned uplink scheduling request resources is selected for transmission of scheduling requests.

18. A user equipment UE for single carrier frequency division multiple access SC-FDMA within a wireless system, comprising:
one or more processors configured to; receive an assignment of a first type of uplink scheduling request resource comprising a first plurality of subcarriers of the wireless system; detect a chance in activity of the UE, wherein the chance in activity is related to one or more applications resident on the UE; determine, in response to the detected chance in activity, that a change in uplink scheduling request resource type should be made; upon determining that a change in scheduling request resource type should be made, select a second type of uplink scheduling request resource comprising a second plurality of subcarriers for transmission of scheduling requests, wherein one of the first type or the second type is an unscheduled shared SC-FDMA resource assigned to a plurality of UEs of the wireless system and an other of the first type or the second type is a dedicated SC-FDMA resource assigned to only the UE, wherein the second plurality of subcarriers are located within a same system bandwidth as the first plurality of subcarriers; and transmit a signal comprising an encoded user ID on subcarriers used for the unscheduled shared SC-FDMA resource. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26)

27. A non-transitory computer-readable medium storing instructions to cause a processor to perform operations comprising:
-
receiving, at a user equipment (UE), an assignment of a first type of uplink scheduling request resource comprising a first plurality of subcarriers of a wireless system; detecting, at the UE, a change in activity of the UE, wherein the change in activity is related to one or more applications resident on the UE; determining, at the UE and in response to the detected change in activity, that a change in uplink scheduling request resource type should be made; upon determining that a change in scheduling request resource type should be made, selecting, at the UE, a second type of uplink scheduling request resource comprising a second plurality of subcarriers for transmission of scheduling requests, wherein one of the first type or the second type is an unscheduled shared SC-FDMA resource assigned to a plurality of UEs of the wireless system and an other of the first type or the second type is a dedicated SC-FDMA resource assigned to only the UE, wherein the second plurality of subcarriers are located within a same system bandwidth as the first plurality of subcarriers; and transmitting a signal comprising an encoded user ID on subcarriers used for the unscheduled shared SC-FDMA resource. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35)
