Preconfigured short scheduling request cycle

摘要

In communication systems, for example Long Term Evolution (LTE) of the 3rd Generation Partnership Project (3GPP), using two cycles (long and short) to configure uplink (UL) scheduling request (SR) resources, and various ways of configuring a short scheduling request cycle may be able to add flexibility for a network (NW) to configure scheduling request cycles, allowing balance between latency and resource reservation. A method, according to certain embodiments, can include detecting that there is data activity associated with a user equipment and activating a short scheduling request cycle upon the detecting the data.

1. A method, comprising:
receiving a message for configuring scheduling request resources; and activating a configured scheduling request resource in response to another reception separate from the configuring message, wherein the activating comprises receiving radio resource control signaling or media access control (MAC) control element or receiving signaling on a physical downlink control channel, and wherein a subframe offset of the scheduling request resource is derived from a subframe of the physical downlink control channel.
