摘要： An apparatus for use in a UE includes processing circuitry coupled to a memory. To configure the UE for SSB processing in a 5G-NR network, the processing circuitry is to decode a MIB and a SIB received from a gNB. An RRC IE within the SIB is obtained. The RRC IE includes a bitmap associated with an SSB transmission pattern, where a length of the bitmap indicates a number of beams used within a cell of the gNB. SSB indices corresponding to candidate SSB positions within a discovery reference signal (DRS) transmission duration are determined based on the number of beams. Synchronization with the cell of the to gNB is performed using SSBs received within the DRS transmission duration, the SSBs selected based on the determined SSB indices.

摘要： A method and apparatus are provided for feedback for closed-loop transmitting with multiple transmit antenna elements and multiple receive antenna elements. A base station includes a codebook containing sets of weightings for the multiple transmit antenna elements, with each set of weightings identified by an index and the codebook known to the base station and a served mobile station (MS). The base station pre-codes pilot signals using a precoding matrix, preferably a unitary matrix, to produce pre-coded pilot signals, which precoding matrix may or may not be known to the MS and which precoding matrix may or may not be included in the codebook. The base station then transmits the pre-coded pilot signals to the MS via the multiple transmit antenna elements and, in response, receives an index to a set of weightings in the codebook for use in a subsequent transmission of a data stream.

摘要： An apparatus for a base station configured for operation in a C-RAN includes processing circuitry coupled to a memory. To configure the base station for multi-user multiple input multiple output (MU-MIMO) signal processing, the processing circuitry is to decode a plurality of sounding reference signals received from a corresponding plurality of UEs via a corresponding plurality of channels. The plurality of channels are estimated based on the plurality of sounding reference signals. A beamforming matrix is determined based on a channel matrix corresponding to the plurality of channels. Beamforming is performed on a plurality of uplink (UL) data streams received from the plurality of UEs, to generate a plurality of beamformed streams. The beamforming is based on the beamforming matrix. Interference suppression is performed on the plurality of beamformed streams to generate a plurality of output data streams. The interference suppression is based on non-orthogonal DMRSs received from the UEs.

摘要： The specification and drawings present a new method, apparatus and software related product (e.g., a computer readable memory) for network management through a hierarchical architecture with a control functionality of a network server (e.g., C-SON) in relationship to clusters comprising eNBs (access points), and for implementing coordinated multi-point (CoMP) transmission and reception in conjunction with inter-cell interference coordination (ICIC) in wireless networks such as LTE wireless networks. In particular, embodiments of the invention describe control and coordination mechanisms among the network elements for different network architectures and use-case scenarios. Such mechanisms may be managed by a centralized self-organizing network controller such as C-SON and hierarchically via localized controllers (such as cluster coordinators) residing in macro eNBs depending on system architectural constraints and network state. A fault-tolerant mechanism then may be defined to recover from failure of controlling sub-elements so that the network remains stable at all times.

摘要： The present invention provides a computationally efficient technique for compression encoding of an audio signal, and further provides a technique to enhance the sound quality of the encoded audio signal. This is accomplished by including more accurate attack detection and a computationally efficient quantization technique. The improved audio coder converts the input audio signal to a digital audio signal. The audio coder then divides the digital audio signal into larger frames having a long-block frame length and partitions each of the frames into multiple short-blocks. The audio coder then computes short-block audio signal characteristics for each of the partitioned short-blocks based on changes in the input audio signal. The audio coder further compares the computed short-block characteristics to a set of threshold values to detect presence of an attack in each of the short-blocks and changes the long-block frame length of one or more short-blocks upon detecting the attack in the respective one or more short-blocks.

摘要： An apparatus and system to provide an enhanced repetition mechanism for PUCCH coverage enhancement are described. The resource allocation and handling mechanisms for collisions with semi-static downlink symbols and invalid symbols are described. The UE receives a PUCCH resource in RRC signalling. The PUCCH resource includes a starting symbol and number of symbols of a PUCCH repetition in a slot and a repetition factor that indicates a number of repetitions. For contiguous repetitions, a repetition that crosses a slot boundary is dropped or segmented. A segmented portion equal to 3 symbols is not transmitted.

摘要： An apparatus for use in a base station includes processing circuitry coupled to a memory. To configure the base station for channel access in a New Radio (NR) unlicensed (NR-U) network operating in an unlicensed spectrum, the processing circuitry is to perform an LBT procedure for a transmission occasion of a plurality of transmission occasions within a Discovery Measurement Timing Configuration (DMTC) window of a communication channel in the unlicensed spectrum. The transmission occasion is configured within a slot of a plurality of slots forming the DMTC window. A Discovery Reference Signal (DRS) is encoded for transmission to a UE on the communication channel, based on the successful completion of the LBT procedure. The DRS includes a PSS, a SSS, and a PBCH. A RACH procedure is performed with the UE, the RACH procedure initiated based on the PSS, the SSS, and the PBCH.
