Abstract: Embodiments of a User Equipment (UE) and methods of communication are generally described herein. If a higher layer parameter altMCS-Table is configured, and a physical downlink shared channel (PDSCH) is assigned by a downlink control information (DCI) format 1, 1B, 1D, 2, 2A, 2B, 2C, or 2D, the UE may, for some subframe/frame configurations, determine a number of physical resource blocks (PRBs) for the transport block as a maximum of: 1; and a floor function applied to a product of a total number of allocated PRBs, a parameter dependent on a special subframe configuration, and a scaling parameter. For other subframe/frame configurations, the UE may determine the number of PRBs for the transport block as a maximum of: 1; and the floor function applied to a product of the total number of allocated PRBs and the scaling parameter.

Abstract: Technology is discussed for mitigating interference in a wireless communication environment where adjacent cells can have asynchronous Time Division Duplexing configurations. Measurements can be taken at an illuminated evolved Node B (eNodeB) of DownLink (DL) transmissions from a transmit eNodeB. These measurements can be relayed to the transmit eNodeB over a backhaul link and used to make scheduling, transmission power, and/or beam forming decisions to reduce the potential for DL interference. To reduce UpLink (UL) interference, sub-frame specific measurements can be requested by a transmit eNodeB of a User Equipment (UE) that would receive DL transmission from the transmit eNodeB to detect interference from any UEs performing UL transmission to an adjacent eNodeB. The interference measurements can be used by the transmit eNodeB to make scheduling determinations to mitigate the interference.

Abstract: Embodiments relate to apparatus for wireless interference mitigation within a first User Equipment (UE). The apparatus comprises at least one channel estimator for estimating a first channel transfer function associated with a first received signal designated for the first UE, and for estimating a second channel transfer function associated with a second received, interference, signal. A symbol estimator is responsive to the at least one channel estimator to process at least the first received signal to produce a symbol estimation. A demodulator, which is responsive to the channel estimator, demodulates the symbol estimation to an output representing a received data unit corresponding to the symbol estimation. The demodulator has a processing unit arranged to demodulate the symbol estimation using the first channel transfer function, the second channel transfer function and a respective modulation scheme for at least the first received signal.

Abstract: Technology is discussed for supporting wireless communication paths from an antenna array with a vertical directional component. Examples reduce training feedback for increased numbers of communication paths by only reporting on a subset of Reference Signals (RSs) provided for various vertical beam configurations. Additional examples reduce feedback with virtual measurements based on a difference between RS measurements. One such measurement can come from full set of RSs for a reference beam configuration and another from a partial set of RSs for an additional beam configuration. Such virtual measurements can also be based on cross correlation for beamforming weights associated with the two configurations. Several examples of preparing and sending measurement reports consistent with Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) standards are discussed. The supporting technology also increases diversity and reduces a power differential between spatially multiplexed layers transmitting a common codeword.

Abstract: Examples include techniques for using a modulation and coding scheme (MCS) for downlink transmissions. In some examples information elements (IEs) for either a physical multicast channel (PMCH) or a physical multicast control channel (PMCCH) include information to indicate an MCS for downlink transmission over a PMCH or PMCCH between an evolved Node B (eNB) and user equipment (UE). For these examples, the information in the IEs include indications of whether higher order modulation for quadrature amplitude modulation (QAM) have or have not been enabled. Both the UE and the eNB may operate in compliance with one or more 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) standards.

Abstract: Embodiments for providing virtual carrier sensing for LTE are generally described herein. In some embodiments, a first evolved Node B (eNB) sends a notification of subsequent DL transmission to a first UE in a downlink. In the uplink, the first UE sends a confirmation of the received DL notification. A second eNB overhears the confirmation, decodes it and extracts the information of the DL resources that the first eNB is planning to use. If the second eNB is not already transmitting in the indicated DL resources, the second eNB marks the indicated DL resources as busy and refrains from transmitting in those resources. The second eNB may then reschedule its transmission using alternative resources so that interference from the second eNB1 may be avoided.

Abstract translation: 本文通常描述了用于LTE的虚拟载波感测的实施例。 在一些实施例中，第一演进节点B（eNB）在下行链路中向第一UE发送后续DL传输的通知。 在上行链路中，第一UE发送接收的DL通知的确认。 第二个eNB窃听确认，对其进行解码并提取第一个eNB计划使用的DL资源的信息。 如果第二eNB尚未在所指示的DL资源中发送，则第二eNB将所指示的DL资源标记为忙，并且避免在这些资源中发送。 然后，第二eNB可以使用替代资源重新安排其传输，从而可以避免来自第二eNB1的干扰。
