In general, the current subject matter relates to transmission of channel state information reference signals (CSI RSs). In some implementations, a message can be received at a radio unit (RU) of a base station in a wireless communication system. The message can include channel state information reference signal (CSI RS) configuration information that the RU is configured to use in generating a CSI RS for transmission to a user equipment (UE). The CSI RS configuration information can include a plurality of parameters including a bandwidth for CSI RS transmission, amplitude scaling, and a scrambling identity (ID).

Transmission of channel state information reference signals

A method, a system, and a computer program for performing beam space compression. At least one signal is received at a first communication device. The first communication device is communicatively coupled to a second communication device using at least one communication interface. One or more beamforming coefficients are generated for transmission of the received at least one signal to the second communication device using one or more first antenna ports of the first communication device. One or more multi-dimensional, multi-domain compression is applied to the generated one or more beamforming coefficients. The received signal is transmitted using one or more first antenna ports associated with the one or more compressed beamforming coefficients to the second communication device.

In general, the current subject matter relates to flexible carrier bandwidth handling in wireless communications systems. In some implementations, a first signal at a first one of a plurality of fixed operating bandwidths defined for a cellular network and a second signal at a second one of the plurality of fixed operating bandwidths defined for the cellular network can be received at a first communication device in the cellular network from a second communication device in the cellular network. The first and second signals can have a subcarrier overlap, the first and second signals can each include at least one null subcarrier value and at least one non-null subcarrier value. The first and second signals can be combined into a single signal that does not include the at least one null subcarrier values of the first and second signals.

Some embodiments address unique challenges of provisioning RPA software to airgapped hosts, and in particular, provisioning RPA machine learning components and training corpora of substantial size, and provisioning to multiple airgapped hosts having distinct hardware and/or software specifications. To reduce costs associated with data traffic and manipulation, some embodiments bundle together multiple RPA components and/or training corpora into an aggregate package comprising a deduplicated collection of software libraries. Individual RPA components are then automatically reconstructed from the aggregate package and distributed to airgapped hosts.

A base station for communicating with a mobile station, the base station including a processor configured to generate, when the base station is operating as a target base station, a path switch request, and a transceiver circuit configured to transmit, when the mobile station is engaged in a handover to the base station when operating as a target base station, the path switch request to a Mobility Management Entity (MME), wherein the path switch request includes a closed subscriber group (CSG) access mode of the base station operating as a target base station.

A communication apparatus which communicates with a base station, the communication apparatus includes a receiving circuit configured to receive a message from the base station, wherein the message includes at least information identifying if the base station is a hybrid access mode base station; and a transmission circuit configured to transmit a parameter which identifies a user equipment to the base station when the base station is the hybrid access mode base station.

Communications system

A communication system is described in which a NATed IP address of a home base station is communicated to the home base station by a home base station gateway or a mobility management entity. In one embodiment, the gateway or the mobility management entity receives the NATed IP address from a security gateway that is used to establish a secure tunnel with the home base station through an IP network.

A communication system is presented in which a base station operates a each of a plurality of cells using a respective component carrier. When the base station decides to configure a mobile telephone to use additional cells of the plurality of cells, a access control procedure is initiated to determine for each cell whether the configuration should be allowed.

A communication system is described in which a handover procedure is provided to allow a mobile device to transfer from a home base station connected to a core network via a home base station gateway to another base station not coupled via the home base station gateway. A novel extension to the handover procedure is provided in which the home base station gateway is informed of the transfer of the mobile device, allowing context and resources assigned to the mobile device at the base station gateway to be released.

Data to be transmitted to a user device may be received at a network device. It may be determined that the user device has network connectivity to the network device via a wide area wireless network connection and that the user device also separately has connectivity to the network device via a local area wireless network connection to an access point. The data may be split so that some portion of the data is to be transmitted by the wide area wireless network connection and another portion of the data is to be transmitted by the local area wireless network connection.
