Method, apparatus, and computer program product for a user equipment to receive a downlink control information message from an access point in a wireless communications network and to echo a new beam index in the PUCCH feedback resource in response to the message indicating a PUCCH feedback resource and containing a beam change information or in response to the message indicating a downlink grant containing a beam change indication MAC control element but so CSI-feedback is scheduled for the PUCCH feedback resource. If a scheduling request resource is indicated by the message or the MAC control element, the user equipment is triggered to transit a scheduling request on that indicated scheduling request resource. If a scheduling request resource is not indicated by the message or the MAC control element, the user equipment is triggered to perform a scheduling request procedure on a periodic scheduling request resource.

Method and apparatus used for communicating a beam change indication based on an actual beam index value and logical beam index value validation

Various communication systems may benefit from the appropriate selection of aspects of operation of the communication system. For example, certain wireless communication systems, such as fifth generation (5G), long term evolution advanced (LTE-A), and wireless local area network (WLAN) communication systems, may benefit from appropriate random access preamble selection. A method can include determining that a user equipment should consider at least one beam-specific parameter. The method can also include indicating to the user equipment to consider the at least one beam-specific parameter.

Random access preamble selection

The application relates to an addressing system for a wireless communication network. The system comprises a first communication device and a second communication device. The first and second communication devices belong to a group of plurality of communication devices of the network. Each communication device is configured to provide a bi-directional radio communication with at least one of the plurality of communication devices. Each communication device has a long node identifier (L-ID) for addressing said communication device and for being used in at least one security procedure of communication in the network. Each communication device is configured to generate a short node identifier (S-ID) for identifying said communication device in a dedicated communication between it and other communication device belonging to the plurality of communication devices.

Addressing system for a wireless communication network

The invention relates to a communication apparatus comprising a processor part, and a data transfer part. The apparatus is configured to receive, by the data transfer part, a packet comprising a network identification code (NIC) of a communication apparatus that transmitted the packet. A header field of the packet comprises a first part of the NIC and a second part of the NIC is included in another field of the packet. The apparatus is further configured to define, by the processor part, that the received packet is from a network to which the communication apparatus belongs, if the first part of the NIC of the received packet corresponds to the first part of the NIC of said communication apparatus. The invention relates also to method for a communication apparatus, a communication system, a computer program, and a computer readable medium.

Solution for separating transmissions from different networks

A method is provided including configuring by a first network node (-S) a timer for a UE () which is started when an inactivity criteria is met, upon expiry of the timer, allowing cell reselection for the UE () based on a frequency criteria between a first frequency and at least a second frequency; and forwarding the UE context by the first network node (-S) controlling the first frequency to at least a second network node (-T) controlling the at least second frequency.

Handling UE context upon inactivity

The application relates to a wireless mesh communication system () that comprises a plurality of radio nodes (). Each of the plurality of radio nodes is configured to provide a bi-directional radio communication with other radio node () of the system and to obtain () an assisted GNSS (A-GNSS) assistance data used in a global navigation satellite system (GNSS) positioning. Also, at least one () of the radio nodes indicates () to other radio nodes () of the system that the A-GNSS assistance data is available and transmissible on request, if the at least one of the radio nodes has this A-GNSS assistance data.

A-GNSS positioning in wireless mesh communication system

Various communication systems may benefit from reliable random access. For example, fifth generation (5G) wireless communication systems may benefit from a coordinated reliable random access technique based on common random access channel resources for a quality of service aware multi-connectivity link. A method can include preparing a random access message at a user equipment. The method can also include transmitting the random access message from the user equipment on a shared resource. The shared resource can include a resource, such as a random access channel, known by a plurality of access nodes or shared by a plurality of access nodes.

Common random access channel resource based coordinated random access

Because the current RRC: ACTIVE SET UPDATE message presently used in soft handover does not contain HS-DSCH related information, which could be utilized for a Serving HS-DSCH cell change, a separate Radio Bearer Control procedure is needed between the UE () and the RNC () for carrying out the Serving HS-DSCH cell change. Should HS-DSCH related information&#x2014;applicable to Serving HS-DSCH cell change&#x2014;be added to the RRC: ACTIVE SET UPDATE message (), an unnecessary Radio Bearer Control procedure is avoided, and the drawbacks of the current method are overcome.

Active set update (ASU) with high speed downlink shared channel (HS-DSCH) information

The invention relates to a wireless communication system (), comprising a plurality of radio nodes, each being able to operate at least as a router node () or as a non-router node (). Each of the plurality of radio nodes is configured to: detect density of the router nodes () within its neighbourhood, and make a decision based on the detected density whether to operate as a router node () or as a non-router node (). The invention relates also to a role selection method and a radio node device () for the wireless communication system ().

Role selection method in wireless communication networks

A method includes, at a user equipment, combining a message requesting the radio resource connection and a message requesting at least one service into a single message. The single message is transmitted from the user equipment to a network element in a wireless network. Another method includes receiving, from a user equipment, a single message including both a message requesting a radio resource connection and a message requesting at least one service. In response to the message requesting radio resource connection, performing radio resource control connection establishment for the user equipment in order to establish the radio resource control connection between the user equipment and at least one of a plurality of network elements of a wireless network.

The definition and use of an additional timer for the MAC-hs reordering function in a user equipment. The timer counts transmission time intervals and is reset each time that the user equipment receives a data packet. If the timer reaches a set value, indicating a sufficiently long period of inactivity, then the transmission sequence number is reset to zero or another predefined value. A base station can run a similar timer and, after the timer reaches a set value, can consider the user equipment as no longer being active.
