Communication system
First Claim
1. A communication apparatus which is operable to communicate with at least one of a first type user equipment (UE) and a second, coverage enhanced, type UE, wherein the coverage enhanced type UE is a UE for which transmissions are repeated in time domain in accordance with one of a plurality of coverage enhancement levels, wherein each coverage enhancement level employs a respective number of repetitions, the communication apparatus comprising:
- a transceiver circuit configured to transmit a control signal, wherein the control signal comprises a first resource configuration for a first physical random access channel (PRACH) for the first type UE and a second resource configuration for a second PRACH for the second type UE, wherein said second resource configuration comprises a respective PRACH configuration for each of the plurality of levels of coverage enhancement,wherein the transceiver circuit is further configured to transmit the second resource configuration for the second PRACH via higher layers; and
wherein the transceiver circuit is further configured to receive a random access message based on either one of the first resource configuration and the second resource configuration.

Abstract
A communication system is disclosed in which a communications node allocates resources for potential use by any of a plurality of user communication devices, including first type (e.g. legacy) user communication devices and second type (e.g. machine-type) communication devices. Control data is sent, to the user communication devices, defining communication resources for potential use by any of the user communication devices. The control data includes information identifying a first PRACH resource configuration for a first type user communication device and a second PRACH resource configuration for a second type of device such that the user devices can be distinguished by the PRACH configuration used.
