Systems, methods, apparatuses, and computer program products for generating sequences for zero-tail discrete fourier transform (DFT)-spread-orthogonal frequency division multiplexing (OFDM) (ZT DFT-s-OFDM) reference signals. One method includes adding a zero vector to an input sequence, and performing an iterative manipulation of the input sequence. The performing of the iterative manipulation of the input sequence may include, for example: computing frequency domain response of the sequence, normalizing elements of the computed frequency domain sequence to unitary power while maintaining phase of each of the elements, converting the sequence to time domain, generating a zero-padded sequence by forcing a zero head and tail of the sequence, and repeating the steps until a final sequence with zero-tail and flat frequency response is obtained.

Apparatus, methods, computer program products, systems and circuits are provided that allow for persistent uplink and downlink resource allocations. A method includes: allocating resources to a user equipment for a data flow over a plurality of time intervals with a single signaling event at a wireless network radio network layer; and informing the user equipment of the allocated resources.

A method of allocating resources in a communication system and a station for the communication system is disclosed. The communication system is such that a plurality of user equipment can communicate data on a dedicated channel. In the method a request for communication resources may be sent from a user equipment to the station on a first protocol layer. Priority information is obtained at the station from a data flow on a second protocol layer. Communication resources may then at least partially be allocated based on said priority information.

Methods, apparatus and computer program products are provided. A method includes: providing at least one logical channel flow, wherein each logical channel flow of the at least one logical channel flow has an associated traffic priority; grouping the at least one logical channel flow by the associated traffic priority to form at least one group; determining an aggregate data flow for at least one group; comparing the determined aggregate data flow with at least one threshold value to obtain an indication value; and transmitting the indication value from a user equipment to a base station.

The specification and drawings present a new method, system, apparatus and software product for determining (e.g., calculating) a load measure by a network element (e.g., Node B or any other network element) for optimizing information traffic in communication networks (e.g., wireless communication systems). This load measure may represent the amount of available/excess traffic that a given network element may carry and is a relative measure, which would take into account the total amount of resources available in the system and the amount of resources that are free for carrying only 'important' or 'essential' traffic, using a weighed method described herein.

An apparatus, such as a user equipment, includes a resource unit RU measurement unit coupled to an output of a wireless receiver; an encoder configurable to encode information descriptive of M perceived best ones of N RUs, where each individual RU is assigned a unique number from a set{1,2, . . . ,N}, where there are sets:S={=():1&#x2266;={l, 2, &#x39b;,|S|}, where each vector in set Srefers to a unique RU combination and where there are  elements in the set S; and a wireless transmitter configurable to transmit the encoded information to a wireless network apparatus, such as a base station. The base station includes a decoder operable to decode the encoded information.

In one exemplary aspect thereof the invention provides a method that operates to receive information through at least one input of a protocol layer packet segmentation unit and to dynamically vary packet segment size in accordance with the received information prior to transmission to a receiver. The information received through the at least one input may include information related to channel quality for a channel through which packet data are transmitted to the receiver. The information received through the at least one input may also be or may include information received from at least one of a higher protocol layer or a lower protocol layer.

The invention provides a method, system, and network entity for adaptive setting or reservation of channelization codes and/or power for downlink channel in a communication network, in particular for DSCH and HS-DSCH, using parameters (PtxDSCHallowed, SFmin) for minimum allowed Spreading Factor, SF, and/or allowed power level, the parameters being set depending on the traffic load, the total cell load and/or the availability of channelization codes.

Adaptive reservation of channelization codes and allowed power

The present invention relates to a method and system for scheduling data packets in a base station device of an access network. An information indicating a retransmission status of a data packet is provided to the base station device, and a scheduling priority is allocated to the data packet based on the retransmission status information. Thereby, retransmission packets can be scheduled earlier and round trip times can be reduced, so as to decrease the risk of timeouts and stalling and to loosen buffer requirements.

An apparatus and method for performing an admission control of a terminal device with an antenna array in a cellular network is provided. The admission control decision is based on a direction-specific load determined by an estimation of a load-dependent directional parameter. Additionally, a cell-splitting function with at least two scrambling codes can be implemented.

A method and apparatus for transmitting data from a first node to a second node of a communication system are provided. The method includes, in a first mode of operation, transmitting data via a first communication channel in which the power level of the channel at the first node is not indicated to the second node, and in a second mode of operation transmitting the data via said first communication channel and indicating the power level of the channel at the first node to the second node.

Method of transmitting data where in a first mode, the power level is not indicated in a message and an NPSK modulation scheme is used, and in a second mode, the power level is indicated in a message in an NQAM modulation scheme is used

A wireless communication device, method and system adapted so that, in response to a repeat request indicating a communication signal (because of an error in transmission of the communication signal), the communication signal is wirelessly retransmitted using a remapping of bits into at least partially different frequencies in the retransmission compared to the original transmission.

Mapping strategy for OFDM-based systems using H-ARQ

The present invention relates to a method and a device for controlling power in a network transmitted from a first station to a second station. The second station determines a power target value for a signal received from the first station and sends power control commands to the first station depending on a deviation between said power target value and a received power level. The second station detects faulty data blocks received from the first station and requests retransmission of faulty data blocks from the first station. The adjustment of the power target value to a temporary power target value during the retransmission is performed such that the temporary power target value is calculated depending on the quality of a faulty data block.
