A Network Node, a Communications Device and Methods Therein for Transmission of Uplink Grants

Abstract:

A network node (206) and a method for transmitting uplink grants to a communications device (208), wherein the communications device operates in a service area (206a) served by the network node. The network node determines, based on a load measure on a Physical Random Access Channel, PRACH, between the network node and the communications device in relation to a load threshold, a number of uplink grants that are to be associated with a Random Access Preamble Identity, RAPID, of a PRACH preamble transmission received from the communications device. Further, the network node indicates the determined number to the communications device; and transmits the determined number of uplink grants to the communications device.
