摘要:
Technology is discussed for self-optimization approaches within wireless networks to optimize networks for energy efficiency, load capacity, and/or mobility, together with new, supporting channel state measurements and handover techniques. New, Channel State Information-Reference Signals (CSI-RSs) for yet-to-be-configured Cell-IDentifications (Cell-IDs) can be used to determine whether adjacent transmission cells can provide coverage for transmission cells that can be switched off for energy efficiency during formation of a Single Frequency Network (SFN). New approaches are also discussed to facilitate mobility within such a network. The new CSI-RSs and mobility approaches can also be used to split up such a SFN when changing load demands so require. Additionally, such new approaches can be used to create a SFN with a common Cell-ID where high mobility is required, such as near a roadway, and to break it up where high capacity is required, such as during a period of traffic congestion.

An apparatus may include a transceiver operable to receive a downlink message from a base station for a serving cell, the downlink message allocating a set of control parameters. The apparatus may also include a processor circuit communicatively coupled to the transceiver and an uplink power control module operable on the processor circuit to read the set of control parameters, and apply a signal-to-noise-and-interference (SINR) parameter based on the received set of control parameters to determine physical uplink shared channel (PUSCH) power to be applied for a PUSCH transmission. Other embodiments are disclosed and claimed.

A signal structure for use in D2D communications is described. In one embodiment, a preamble for automatic gain control at the receiver end is included in the transmitted signal. Techniques for scheduling of D2D transmissions using carrier sensing multiple access (CSMA) and a power control schemes for interference management are also described.

Machine-readable media, methods, apparatus and system for transmitting ACK/NACK signal in a wireless communication system are described. In some embodiments, a sequence corresponding to one of acknowledge (ACK) information and non-acknowledge (NACK) information may be determined. Then, the sequence may be mapped onto a transmission channel for later transmission from the mobile station to a base station. In some embodiments, the transmission channel may be allocated with at least a part of three feedback mini-tiles (FMTs), wherein each of the FMTs comprises two subcarriers contiguous in frequency domain by six orthogonal frequency division multiplexing (OFDM) symbols contiguous in time domain and the three FMTs being discontinuous in frequency domain.

摘要:
An apparatus and method for processing fast feedback payload data to generate symbols for transmission through a fast feedback channel in a wireless network are presented. The technique first encodes payload data using a tail biting convolutional code. The encoded bits are then de-multiplexed to five different data subblocks in a sequential fashion. Subblock interleaving is then used to interleave the data of the subblocks according to a predetermine scheme. A bit selector then selects interleaved subblock bit for output. The selected bits may then be modulated by a modulator using quadrature phase shift keying (QPSK). The resulting symbols may then be mapped to a predetermined fast feedback subcarriers within a feedback channel.
