  • Publication number: 20130301552
    Abstract: The described aspects include methods and apparatus providing MTC in a wireless network. In an aspect, a narrow bandwidth within a wide system bandwidth is allocated for communicating data related to MTC. MTC control data generated for communicating over one or more MTC control channels for an MTC UE within the narrow bandwidth is transmitted over the one or more MTC control channels. The one or more MTC channels are multiplexed with one or more legacy channels over the wide system bandwidth. Other aspects are provided for transmission mode and content of the MTC control data or other MTC data.

  • Publication number: 20130301565
    Abstract: A method of wireless communication occurs in a frequency band having a first set of resources associated with a first carrier type and a second set of resources associated with a second carrier type. In one configuration, the first carrier type is a NCT (NCT) and the second carrier type is a LCT (LCT). LCT UEs may only receive signals from the second carrier type. However, NCT UEs may receive signals from both the first carrier type and the second carrier type. Therefore, to provide backward compatibility while supporting NCT UEs, an eNodeB may signal support of the first carrier type to a NCT UE while maintaining signaling with LCT UEs.

  • Patent number: 8583983
    Abstract: Techniques for supporting high decoding throughput are described. A transmitter may encode a code block of data bits with a Turbo encoder. A receiver may perform decoding for the code block with a Turbo decoder having multiple soft-input soft-output (SISO) decoders. A contention-free Turbo interleaver may be used if the code block size is larger than a threshold size. A regular Turbo interleaver may be used if the code block size is equal to or smaller than the threshold size. The contention-free Turbo interleaver reorders the data bits in the code block such that information from the multiple SISO decoders, after interleaving or deinterleaving, can be written in parallel to multiple storage units in each write cycle without encountering memory access contention. The regular Turbo interleaver can reorder the data bits in the code block in any manner without regard to contention-free memory access.

  • Publication number: 20130294268
    Abstract: A method for mitigating interference in a wireless network includes an eNodeB and/or a UE identifying interference. The eNodeB may identify the interfering TDD configurations based on a downlink signal of a neighboring eNodeB received during an uplink timeslot for a UE associated with the eNodeB. Likewise, the UE may identify an interfering UE based on an uplink signal received during a downlink timeslot for an eNodeB associated with the UE. The eNodeB performs interference management based at least in part on the identified interference.

  • Patent number: 8576692
    Abstract: Techniques for transmitting UE-specific reference signals (UE-RSs) in a wireless network are described. In an aspect, a UE-RS may be transmitted in different manners depending on the number of layers used for data transmission. In one design, a cell may determine subcarriers for a UE-RS based on a frequency shift if data is transmitted on one layer and based on a predetermined set of subcarriers (with no frequency shift) if data is transmitted on multiple layers. In another aspect, a UE-RS may be transmitted on subcarriers determined based on a frequency shift for data transmission on multiple layers. In yet another aspect, a UE-RS may be transmitted from a plurality of cells to a UE for coordinated multi-point (CoMP). In yet another aspect, a UE-RS may be transmitted in a data section of a subframe including only the data section.

  • Publication number: 20130260763
    Abstract: In wireless communication systems, a determination may be made whether to hand off a user equipment (UE) based on whether the UE encounters time varying interference, such as UE to UE interference. The time varying interference may be present only in a specific set of time/frequency resources or subframes. Measurement reporting may be restricted to time/frequency resources which do not experience the time varying interference.

  • Patent number: 8548102
    Abstract: Methods and apparatuses for enhanced processing of received channels in a mobile communications system is described. Particularly, convolutionally encoded tail biting data in a mobile communications system is efficiently decoding by replicating the received encoded signal N times, where N equals a number of iterations. A Viterbi decoding algorithm is applied and a most likely survivor path is obtained. The ensuing decoding window is set as a fixed decoding window and placed at a mid-section of the most likely survivor path. Simulations have shown codeword accuracy to be comparable to MLSE with less complexity. A high degree of accuracy has been obtained for N=3.

  • Publication number: 20130250793
    Abstract: Methods and apparatuses are provided that include selecting reference signal (RS) or other tones to utilize in estimating a channel for decoding one or more channels. Where the RS tones are interfered by other base stations, interference cancelation can be performed over the RS tones. Since interference can vary over the tones, interference cancelation can yield RS tones of varying quality. Thus, a quality of each of the RS tones can be determined, and at least a subset of the RS tones can be selected for estimating a channel. Additionally or alternatively, the RS tones can be weighted or otherwise classified for performing channel estimation using the RS tones.

  • Publication number: 20130250927
    Abstract: Methods and apparatus for partitioning resources for enhanced inter-cell interference coordination (eICIC) are provided. Certain aspects involve broadcasting a message indicating time-domain resource partitioning information (RPI), where a user equipment (UE) may be operating in idle mode. With the RPI, the UE may be able to identify protected resources with reduced/eliminated interference from neighboring cells. The RPI in this broadcasted message may be encoded as a bitmap as an alternative or in addition to enumeration of the U/N/X subframes. Other aspects entail transmitting a dedicated or unicast message indicating the time-domain RPI, where a UE may be operating in connected mode. With the RPI, the UE may be able to determine channel state information (CSI), make radio resource management (RRM) measurements, or perform radio link monitoring (RLM), based on one or more signals from a serving base station during the protected time-domain resources.
