In accordance with an example embodiment of the present invention, a method comprises allocating a control channel resource in a wireless relay transmission frame on a wireless relay link; generating a control signaling based on at least one of a resource allocation scheme, a status of the wireless relay link and a traffic condition of the wireless relay link; mapping the control signaling to the allocated control channel resource via at least one of a time-first mapping, a frequency-first mapping, and a multiplexing mapping; and transmitting the control signaling in the allocated control channel resource on the wireless relay link to at least one associated relay node.

Control signaling for wireless communication

In one aspect thereof the exemplary embodiments provide a method that includes, when in a time division duplex mode of operation with a user equipment, allocating physical uplink control channel resources by reserving physical uplink control channel resources with a granularity of one acknowledge/negative acknowledge (ACK/NACK) bundle; and sending an indication of the allocated physical uplink control channel resources from a network access node to the user equipment.

Enhanced physical uplink control channel format resource allocation for time division duplex mode

A method of transmitting uplink control signals/status bits from a user equipment, said user equipment having multiple transmit antennae, and said control signals correspond to a plurality of previous downlink transmissions, wherein said control signals are transmitted over a plurality of PUCCH resources and over said multiple antennae, and transmitted during a single uplink sub-frame. Use of multiple PUCCH resources and multiple antennae allow greater spatial diversity.

Method of scheduling data

An apparatus, method and system to reduce interference between frequency-division duplex and time-division duplex signals in a communication system. In one embodiment, an apparatus includes a processor () and memory () including computer program code. The memory () and the computer program code are configured to, with the processor (), cause the apparatus to allocate a time-division duplex carrier for a frequency-division duplex downlink signal for communication with a communication element, and employ the time-division duplex carrier with a truncated time duration for the frequency-division duplex downlink signal.

Apparatus and method to reduce interference between frequency-division duplex and time-division duplex signals in a communication system

A method of configuring a component carrier includes determining how timings of receiving and/or sending data for at least two aggregated component carriers in at least one time period are related; and setting the timing of receiving and/or sending data for the at least two aggregated component carriers based on the determining.

Component carrier configuration

An apparatus and a method is described, by which a component carrier configuration, re-configuration, activation or de-activation is performed. In particular, a signaling format used for acknowledgment/negative acknowledgement messages on an uplink control channel is detected, and a codebook size of the acknowledgment/negative acknowledgement messages is decided based on the detected signaling format.

Support of UL ACK/NACK feedback for carrier aggregation during timing uncertainty component carrier (re-) configuration/activation/de-activation period

An apparatus and a method are provided. The provided solution includes a controller configured to determine a transmission mode for user equipment, the transmission mode including non-codebook precoding with fixed precoding granularity; and to control a transceiver to transmit information on the selected transmission mode to the user equipment.

Apparatus and method for non-codebook based precoding

There is transmitted to a user equipment UE in a first subframe of a radio frame a downlink shared channel DSCH according to a first relay-transmission mode (e.g., mode A or A' in the examples); then switch to a second relay-transmission mode (e.g., mode C or C&#x2032; in the examples) within the radio frame based on a channel quality of the DSCH. After switching, then transmit to the UE, in a subsequent subframe of the radio frame, the DSCH according to the second relay-transmission mode. In this embodiment the HARQ process is synchronous and non-adaptive for mode C: the eNB re-transmits packets to the UE in a predetermined fashion to be concurrent with transmission of those same packets from the relay node, as scheduled by the eNB. In this embodiment the eNB receives the UE's NACK for the data that is to be retransmitted via relay through the relay node.

Adaptive transmission modes for transparent relay

The specification and drawings present a method, apparatus and software related product (e.g., a computer readable memory) for improving device discovery and D2D operation, e.g., in LTE wireless systems, by using control signaling provided by a wireless network (e.g., by an eNB). The discovery channel/channels which conveys discovery signal/signals are configured by a network (e.g., by the eNB) and are mapped to control channel/channels (e.g., one-to-one). After sending/receiving the discovery signal/signals, the D2D devices are monitoring control channel/channels to get current information for establishing the D2D communication among these D2D devices, the current information may include a resource allocation for the D2D communication and a device list of candidates for establishing the D2D communication.

In accordance with exemplary embodiments of the invention there is a method and apparatus to detect with a hybrid automatic repeat request function a collision between an uplink packet re-transmission and a new uplink packet transmission within a hybrid automatic repeat request process, and in response, to dynamically allocating resources for transmitting the new uplink packet transmission in a different hybrid automatic repeat request process that does not collide with the uplink packet re-transmission. In accordance with other exemplary embodiments of the invention, there is a method and apparatus to transmit a packet re-transmission in a hybrid automatic repeat request process using a semi-persistently scheduled uplink resource, and responsive to receiving a dynamic allocation of a different hybrid automatic repeat request process, to transmit a new packet using the dynamically allocated different hybrid automatic repeat request process.
