Abstract: A communication system is described in which machine-type communication devices having a reduced bandwidth can be allocated physical uplink control channel resources that fall within that reduced bandwidth whilst other, legacy, devices can continue to use physical uplink control channel resources that do not fall within that reduced bandwidth.

Abstract: A communication system is disclosed in which minimum system information associated with a cell of a radio access network (RAN) is transmitted by a base station. The minimum system information comprises parameters for accessing a cell of the base station, divided into an initial part and a remaining part of the minimum system information. The base station transmits the initial part of the system information via a broadcast channel using a first set of communication resources; transmits information identifying an allocation of at least one further communication resource in a shared channel; and transmits the remaining part of the minimum system information using the at least one further communication resource identified by the allocation.

Abstract: A method in a relay station includes communicating with a base station, determining if a control signal is included in a subframe, and decoding data in the subframe if the control signal is included in the subframe. The control signal includes a parameter which is related to a quantity of resource blocks.

Abstract: A communication system is disclosed in which a ProSe Relay UE allows a remote UE to connect to a base station and core network through the Relay UE. The base station broadcasts that it is capable of supporting ProSe Relay UEs. UEs that are in poor coverage areas can identify that the base station supports ProSe Relaying and can search for a relay UE with which to connect prior to trying to establish a direct connection with the base station. The Relay UE and the base station maintain context information for the relayed UE so that messages can be properly routed through the network and through the Relay UE.

Abstract: A communications node operable to communicate with another communications node over a communications channel having a plurality of frequency resources, the communications node includes data defining a division of the communications channel into a plurality of contiguous sub-bands each having N frequency resources, wherein each frequency resource in a sub-band has a corresponding frequency resource in each of the other sub-bands, data defining an initial allocation of the frequency resources, a resource determination module operable to apply a frequency shift to the initially allocated frequency resources in accordance with a frequency hopping sequence to determine frequency resources to use for communicating information with the other communications node, wherein the frequency shift applied moves the initially allocated frequency resources to corresponding frequency resources in another sub-band, a transceiver for communicating information with the other communications node using the determined frequency resource.

Abstract: A communication system is disclosed in which a base station communicates with user equipment via an associated cell having a system bandwidth. The system bandwidth comprises a bandwidth part having a set of contiguous physical resource blocks. The base station initiates a random access procedure with the user equipment; provides first information identifying a set of frequency resources for an uplink channel; and provides second information identifying at least one specific frequency resource, within said set of frequency resources, for said uplink communication. The first information is provided prior to completion of the random access procedure.

Abstract: A communication system is disclosed in which a communication device and a base station initially communicate using a first bandwidth. The communication device monitors for control data transmitted, by the base station, using a first control resource set conveyed in the first bandwidth. The communication device and the base station switch to using a second bandwidth, wherein the second bandwidth is different to the first bandwidth, and the communication device monitors for control data transmitted, by the base station, using a second control resource set that is conveyed in the second bandwidth.

Abstract: A communication system is disclosed in which a base station manages the transmission of on-demand system information to optimise the trade-off between the additional signalling overhead associated with on-demand transmission and the resource usage inefficiencies associated with the sometimes unnecessary transmission of system information on a periodic basis. The base station manages switching from on-demand transmission to periodic transmission, and vice versa, based on one or more utilisation thresholds.

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.
