The embodiments of the invention relate to a transmitter method for multiple antenna systems. The transmitter method contains the step of operating at least one antenna array in a first operation mode by transmitting first transmit signals (TS-, TS-, TS-A) from a first number of antenna elements (AEG) with a first transmit power and the step of operating the at least one antenna array in at least one second operation mode by transmitting at least second transmit signals (TS-, TS-, TS-B, TS-, TS-C, TS-C) from at least one second number of antenna elements (AEG, AEG) smaller than the first number of antenna elements with at least one second transmit power larger than the first transmit power. The embodiments of the invention further relate to a transmitter apparatus for multiple antenna systems. The transmitter apparatus contains means for operating at least one antenna array in a first operation mode by transmitting first transmit signals (TS-, TS-, TS-A) from a first number of antenna elements (SUB-G) with a first transmit power and for operating the at least one antenna array in at least one second operation mode by transmitting second transmit signals (TS-, TS-, TS-B, TS-, TS-, TS-C) from at least one second number of antenna elements (SUB-G, SUB-G) smaller than the first number of antenna elements with at least one second transmit power larger than the first transmit power. The embodiments of the invention even further relate to a network node, which contains the transmitter apparatus.

Embodiments relate to an apparatus, a base station transceiver, a method, and a computer program for assigning a radio resource. An apparatusfor a mobile communication system is operable to assign a radio resource from a plurality of radio resources to enable communication of information between a mobile transceiverand a base station transceiver. The apparatuscomprises a schedulerfor determining the radio resource based on information on a transmission condition between the mobile transceiverand the base station transceiver, and based on a first allocation rule of a first operator and based on a second allocation rule of a second operator.

The invention relates to a method for joint processing of uplink data (g(n), s(n)) transmitted from at least one user equipment (UE, UE) to a plurality of coordinated reception points (BS, BS) of a wireless communication system (), the method comprising: estimating and preferably compensating for individual propagation delays of the uplink data (g(n), s(n)) transmitted from one of the user equipments (UE, UE) to the coordinated reception points (BS, BS), and compensating a timing difference between a propagation delay of a coordinated reception point (BS, BS) which serves the user equipment (UE, UE) and at least one propagation delay of at least one coordinated reception point (BS, BS) which does not serve the user equipment (UE, UE) for performing the joint processing of the uplink data (g(n), s(n)), wherein the step of compensating the timing difference comprises modifying a channel matrix (H) associated with uplink channels from the at least one user equipment (UE, UE) to the coordinated reception points (BS, BS). The invention also relates to a processing arrangement (BS, BS) adapted for performing the method.

Method and processing arrangement for joint processing of uplink data

The invention provides a method of operating a first base station () as a reception station for a wireless uplink communication connection with a wireless appliance (), wherein the method comprises: controlling the wireless uplink communication with the wireless appliance, receiving a signal () from the wireless appliance, receiving a rest signal () from at least one second base station (), and analyzing the rest signal from the at least one second base station for detecting a signal () from the wireless appliance that is above a threshold.

Uplink communication in a wireless communication network

In a wireless network, for example, an LTE network, the context information relating to a mobile terminal UE is transmitted to a plurality of network nodes eNBandfrom a source network node, eNB. One of the eNBis a handover target node and also reserves resources for the UE in anticipation of receiving it after handover. The other eNBsanddo not reserve resources. In the event of radio link failure, the UE may attach to one of the designated eNBsandthat have not reserved resources, but that do recognize the UE because they have received its context. The method reduces the likelihood of the UE needing to go via the time consuming IDLE state while only reserving resources at a handover target eNB.

Method and apparatus for radio link failure recovery in a wireless communications network

In a method for radio link failure (RLF) recovery in a wireless communications network, a timer T sets a predetermined time period from a command to a mobile terminal UE to hand over to a new eNB. Resources are reserved at a target eNB. If the time period expires without the UE attaching to the target eNB, the source eNB requests other candidate eNBsandto reserve resources. Once the UE associates with the target eNB, the resources reserved at candidate eNBsandare released. If the UE associates with the target eNBprior to expiry of the time period T, resources are not unnecessarily reserved at the candidate eNBsand. If the UE associates with one of the candidate eNBinstead of the target eNB, resources have already been reserved, enabling RLF recovery to be implemented without the UE going via LTE_IDLE, in an LTE arrangement.
