A base station is configured to transmit at least one signal in a first bandwidth portion of a cell, the at least one signal having a primary synchronization signal (PSS), a secondary synchronization signal (SSS) and a physical broadcast channel (PBCH). The PBCH including a master information block (MIB), the MIB having an indication of time and frequency resources in relation to the at least one signal to acquire additional system information, the first bandwidth portion having a bandwidth less than a full bandwidth of the cell. The base station is further configured to transmit in time and frequency resources associated with the indication of the time and frequency resources and additional system information. The additional system information indicates a second bandwidth portion of the cell, the acquired additional system information being acquired within the second bandwidth portion.

Communication in a wireless network using restricted bandwidths

The user equipment (UE) is configured to receive at least one signal in a first bandwidth portion of a cell. The at least one signal having a primary synchronization signal (PSS), a secondary synchronization signal (SSS) and a physical broadcast channel (PBCH). The PBCH includes a master information block (MIB), the MIB having an indication of time and frequency resources in relation to the at least one signal to acquire additional system information, the first bandwidth portion having a bandwidth less than a full bandwidth of the cell. The user equipment (UE) is further configured to receive, based on the indication of the time and frequency resources, additional system information, the additional system information indicating a second bandwidth portion of the cell, the acquired system information being acquired within the second bandwidth portion.

The user equipment (UE) configured to receive a physical broadcast channel (PBCH) in a first bandwidth portion of a cell having a cell bandwidth, the PBCH having a master information block (MIB), the MIB having a carrier flag and an indication of a second bandwidth portion of the cell. The UE is further configured to receive the second bandwidth portion of the cell based on a first value on the carrier flag and recover control information from the second bandwidth portion.

The base station (BS) may transmit, to a user equipment (UE), control information indicating reserved resources, wherein the control information indicates a time pattern of the reserved resources and indicates frequency resources of a cell bandwidth of the reserved resources, wherein the indicated frequency resources are a portion of the cell bandwidth. The BS may further transmit, to the UE, physical downlink shared channel transmissions in resources of the cell bandwidth outside of the reserved resources.

User equipment (UE) may receive a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH) including a master information block (MIB). Further, the PSS, SSS and PBCH are in a first bandwidth of a cell having a cell bandwidth, wherein the first bandwidth is a first portion of the cell bandwidth. The MIB includes an indication of frequency resources and time resources for use in acquiring additional system information. The UE may further acquire the additional system information using the indication of the frequency resources and the time resources.

A user equipment (UE) may receive, from a base station, control information indicating reserved resources, wherein the control information indicates a time pattern of the reserved resources and indicates frequency resources of a cell bandwidth of the reserved resources, wherein the indicated frequency resources are a portion of the cell bandwidth.

The base station (BS) may transmit a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH) including a master information block (MIB). Further, the PSS, SSS and PBCH are in a first bandwidth of a cell having a cell bandwidth, wherein the first bandwidth is a first portion of the cell bandwidth. The MIB includes an indication of frequency resources and time resources for use by user equipments (UEs) to acquire additional system information. The BS may transmit control information using the indication of the frequency resources and the time resources for the UEs to acquire the additional system information.

User equipment (UE) may receive a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH) of a cell having a cell bandwidth. The PBCH may include a master information block having an indication of a frequency bandwidth of control information associated with a restricted bandwidth. The restricted bandwidth may be a part of the cell bandwidth and be less than the entire cell bandwidth. The UE may receive the control information, based on the received PBCH, and to receive additional system information within the restricted bandwidth.

A mobile communications system including at least one base station configured to communicate data to/from different types of terminal devices via respective of plural logically separate carriers of a wireless access interface; first and second terminal devices operable to respectively camp-on to first and second carriers of the carriers and to subsequently communicate data with the at least one base station via the first and second carriers. The first and second carriers support compatible synchronization signalling such that the first and second terminal devices synchronize with the first and second carriers to begin a camp-on procedure, and following synchronization with one of the first or second carriers to begin a camp-on procedure. The second terminal device is configured to determine whether or not to continue with the camp-on procedure based on an aspect of physical layer signalling associated with a control channel of the carrier with which it has synchronized.
