[0021] Advanced Radio Access Technology for Long Term Evolution (4G)

[0022] figure 1 A schematic diagram is provided showing some basic functions of a mobile telecommunication network / system 100 operating generally according to FTE principles, but which may support other radio access technologies as well, and which may be adapted to implement the present disclosure as described herein implementation. figure 1 Specific aspects of the individual elements in and their corresponding modes of operation are well known and defined in relevant standards managed by the 3GPP (RTM) body, and also in numerous books on the subject (e.g., Holma H. ​​and Toskala A [2] ) described in. It should be understood that operational aspects of telecommunications networks discussed herein, not specifically described (e.g., in relation to the The specific communication protocol for inter-communication is related to the physical channel).

[0023] The network 100 includes a plurality of base stati...

Abstract

A method of operating a communications device in a wireless communications network, the method comprising: transmitting a random access message on a wireless access interface, the random access message comprising a selected random access preamble and transmissions on a shared channel, the shared channel transmissions using a demodulation reference signal (DMRS) according to selected one or more DMRS parameters; receiving a resource allocation message including an indication to transmit the resource allocation message in response to the random access message and an indication to allocate downlink communication resources for transmission of the random access response message; receiving a signal transmitted using the allocated downlink communication resource; determining that the resource allocation message identifies the communication device; and in response to determining that the resource allocation message identifies the communication device, decoding a signal transmitted using the allocated downlink communication resource; wherein the resource allocation message includes an indication to identify the communication device based on an index associated with the selected random access preamble and one or more of the selected one or more DMRS parameters.

Description

technical field [0001] The present disclosure relates to a communication device, an infrastructure device, and a method for the communication device to receive data in a wireless communication network. Background technique [0002] The "Background" description provided herein is for the purpose of generally presenting the context of the disclosure. To the extent described in this Background section, the work of the presently named inventors and aspects of the description that may not be prior art at the time of filing are neither expressly nor implicitly admitted to be prior art to the present invention. [0003] Third and fourth generation mobile telecommunication systems such as UMTS and Long Term Evolution (LTE) architectures defined based on 3GPP are capable of supporting more refined services than the simple voice and messaging services provided by previous generations of mobile telecommunication systems. For example, with the improved radio interface and enhanced data...
