However, in one example, where the number of devices at the base station increases, the time required to recover from a collision on a shared resource channel may be greater than allowing devices to obtain contention-based Authorized time savings

Embodiment Construction

[0035]Various aspects are now described with reference to the figures. In the following description, for purposes of explanation, numerous specific details are given in order to provide a thorough understanding of one or more aspects. It may be evident, however, that the described aspects may be practiced without these specific details.

[0036] As described further herein, devices may be provided with shared scheduling request (SR) resources to send SRs (eg, when an uplink grant is desired to send user plane data). For example, an identifier associated with a shared SR resource along with an indication of the shared SR resource may be signaled to the device for a given duration (eg, every n milliseconds (ms), where n is a positive integer). Accordingly, when an uplink grant is desired, the device may send an SR on shared SR resources associated with one or more received identifiers. This can reduce the delay associated with receiving an uplink grant since the device does no...

Abstract

In accordance with one or more embodiments and corresponding disclosure thereof, various aspects are described in connection with providing shared scheduling request (SR) resources to devices for transmitting SRs. Identifiers related to the shared SR resources can be signaled to the devices along with indications of the shared SR resources in given time durations. Thus, devices can transmit an SR over shared SR resources related to one or more received identifiers for obtaining an uplink grant. This can decrease delay associated with receiving uplink grants since the device need not wait for dedicated SR resources before transmitting the SR. In addition, overhead can be decreased on control channels, as compared to signaling dedicated SR resources and / or uplink grants. Moreover, identifiers related to SR resources can correspond to a grouping of devices, such that a device can transmit over shared SR resources related to a group including the device.

Description

[0001] Claim Priority Pursuant to 35 U.S.C. §119 [0002] This application for patent claims priority to Provisional Application 61 / 290,747, filed December 29, 2009, entitled "LTE SCHEDULING REQUEST OVERLOADING," which is assigned to the assignee of this application and is hereby expressly incorporated by reference way to incorporate it into this article. technical field [0003] In general, the description that follows relates to wireless communications and, in particular, to the transmission of scheduling requests. Background technique [0004] Wireless communication systems are widely deployed to provide various types of communication content such as voice, data, and so on. A typical wireless communication system may be a multiple-access system capable of supporting communication for multiple users by sharing available system resources (eg, bandwidth, transmit power, ...). Examples of such multiple-access systems may include Code Division Multiple Access (CDMA) systems,...
