Reconstruction method of discrete digital signals in noisy overloaded wireless communication systems

A computer-implemented method of estimating transmit symbol vectors transmitted in an overloaded communication channel includes receiving a signal represented by a received signal vector, the received signal vector corresponding to a superposition of signals representing transmitted symbols selected from a constellation of symbols and transmitted from one or more transmitters. Continuous first and second functions in a search space in a convex domain are defined. The first function and the second function are combined into a third function, and a fractional programming algorithm is applied to the third function, targeted to finding an input vector that minimizes the third function. A mapping rule translates the found input vector into an estimated transmit symbol vector, and the estimated transmit symbol vector is output to a decoder for decoding into an estimated transmit symbol from the constellation.

The invention relates to a method for dynamically controlling the PUSCH of a SCell in a backhaul link of a communication system utilizing a relay node with carrier aggregation, where the SCell is inband with respect to the access link between the relay node and the UEs. In order to avoid subframe blocking due to inband operation, the PUSCH of an SCell may be deactivated. The new downlink-only configuration of the SCell allows the relay node to use all resources of the SCell for scheduling resources for uplink and downlink transmissions in the access link. The PUSCH may deactivated and activated e.g. depending on the need for higher data rates in the uplink and downlink of the access link between the relay node and the UEs. The decision to deactivate/activate the PUSCH of an SCell may be taken by the DeNB or the relay node.

The invention relates to a downlink transmission scheme that supports downlink HARQ operation and macro-diversity that is capable of overcoming the problem of HARQ protocol de-synchronization when using HARQ in the downlink with multiple data transmitting network nodes. In this scheme, a distributed HARQ protocol operation for downlink data transmissions involving multiple network nodes is provided, where only one network node is terminating downlink HARQ protocol operation towards to mobile terminal, i.e. retransmissions of a data packet are sent from a single network node, a single HARQ transmitter, to the mobile terminal. The multiple network nodes send a first transmission of the data packet to the mobile terminal in a single transmission time interval using HARQ. One of the multiple network nodes is designated as the HARQ terminating node that controls/handles all retransmissions of the data packet.

The invention relates to a random access procedure for use in a mobile communication system. Furthermore, the invention also provides a mobile terminal and a base station that as suitably adapted to perform the random access procedure as well as the definition of a special format of a random access response message signalled during the random access procedure. To suggest a random access procedure that allows more information to be conveyed in the first scheduled transmission of the random access procedure, the invention proposes a random access procedure for use in a mobile communication system, wherein a base station transmits a random access response in response to receiving a random access preamble from a mobile terminal, wherein the random access response message comprises a grant for a scheduled transmission by the mobile terminal and an indication on the uplink transmission mode for the scheduled transmission.

The invention relates to group communication services, i.e. communication services involving two or more users (or service participants). The invention provides a method for distributing multicast data of a multicast service to different domains and a method for distributing multicast data to service participants in a domain. Further, the invention relates to a control node and system implementing the respective methods. To improve resource utilization when providing a multicast service, including inter alia PoC services, to service participants the invention provides mechanisms to avoid unnecessary multiplication of multicast data in the distribution tree for multicast services with service participants of different domains. For this purpose the controlling node that is initiating the multicast service upon request determined to which domains the multicast data is to be provided and only forwards the multicast data on a per-domain basis. Another aspect of the invention is the avoidance of unnecessary duplications of multicast data within individual domains.

Inter-domain group-communications

The invention relates to a method for distributing control signaling for session control of a multicast or broadcast service within a mobile communication network. Furthermore the invention also provides a base station, mobile terminal and communication system to perform the proposed method. In order to reduce the number of signaling connections for the service, the invention proposes to avoid the initial distribution of session control signaling in the entire mobile communications network or service area. Rather than providing service related control signaling connections upon session start, the control signaling connections are set up in response to service requests of the mobile terminals requesting the service. According to one further aspect, the mobile terminals send the service requests based on service announcements available at the mobile terminals, i.e. in contrast to conventional implementations, the mobile terminals do not await a notification of the access network on the availability of the service within the cell.

Management of session control signaling for multicast/broadcast services

The invention relates to a method and network control node for detecting the point of attachment of mobile terminals moving within a mobile communication network in idle mode, wherein the mobile communication system can be logically divided into plural tracking areas to which the mobile terminals register. Further, the invention relates to a method for enabling management of mobile terminals in idle mode receiving a service within such mobile communication system. Moreover, the invention relates to a method and mobile terminal for updating the mobile terminal's tracking area registration in a mobile communication system being logically divided into plural tracking areas, wherein mobile terminal is in idle mode and is registered to plural tracking areas simultaneously. The invention suggests different mechanism how to detect terminals registering to plural tracking area, how to verify their current location in the network and how to use these information, for example for resource management.

The invention relates to a method for efficiently providing a bidirectional multicast service (e.g. IMS) to a user equipment (), located in a radio cell, controlled by a control entity (). For the downlink data of the bidirectional service a downlink multicast service (e.g. MBMS) is utilized. In case the control entity (e.g. RNC) decides for a point-to-point radio link to the UE, the bidirectional service is notified and system resources, established for the bidirectional service are utilized for providing the bidirectional service downlink data. This includes radio resources in the radio access network and may include connections in the core network. Optionally, the downlink multicast service may be de-activated for the specific mobile terminal, but the system resources already established may be maintained. The invention further relates to a network entity in the CN or in the RAN for configuring system resources and for forwarding the multicast service data to the UE.

Efficient provision of a multicast service by switching between multicast services in a mobile communication system

The invention relates to a method for efficiently setting up a bidirectional multicast service in a mobile communication system. The bidirectional service is provided to a user equipment located in a radio cell controlled by a control entity. For the downlink data of the bidirectional service a downlink multicast service framework is utilized. In case the control entity decides for a point-to-point radio link to the UE, the system resources of the downlink framework are configured so as to re-use the configured system resources of the bidirectional service. This includes radio resources in the radio access network and may include tunnels in the core network. The invention further relates to a network entity in the CN or in the RAN for configuring system resources and for forwarding the multicast service data to the UE. The invention also relates to a mobile terminal for receiving the bidirectional multicast service.

Efficient multicast service data provision in a mobile communication system

The invention relates to a method for managing the mobility of a mobile terminal, while receiving a service via an access node of a mobile communication network. The mobile communication network has overlapping pool areas, while the access node is assigned to at least two pool areas simultaneously. After the UE changes to the access node of the overlapping area, it is proposed that the mobility management entity serving the UE arbitrarily selects a prospect user plane entity for transporting service data into the next pool areas, and requests from the service provider information about UPEs handling this service. After the actual attachment to an access node within the new pool area, the handover is finalized by changing the UPE from the old one to the selected UPE in the new pool area. Thereby, the data path from the service provider to the UE is constantly being optimized.
