Abstract: A method of maximum output power configuration with UE preference in carrier aggregation is provided. A UE configures multiple component carriers (CCs) with carrier aggregation for communicating with a serving base station in a mobile communication network. The UE determines channel condition of multiple serving cells over the corresponding multiple CCs. The UE then determines maximum output power for each CC based at least in part on the corresponding channel condition of each CC. Finally, the UE transmits power headroom report (PHR) for each CC to the serving base station, wherein the PHR is calculated based on the determined maximum output power. As a result, the reported PH information is channel condition dependent, which can be used by eNB for facilitating better transmission scheduling.

Abstract: A receive (Rx) UE performs blind detection to decode a first-stage Sidelink Control Information (SCI) in a received signal. The first-stage SCI contains control information for the Rx UE to locate time-and-frequency resources used by a transmit (Tx) UE. The time-and-frequency resources are used to transmit the first-stage SCI and a second-stage SCI via a Physical Sidelink Control Channel (PSCCH) and to transmit data via a Physical Sidelink Shared Channel (PSSCH) associated with the PSCCH. The Rx UE locates the second-stage SCI in the time-and-frequency resources based on the first-stage SCI. The second-stage SCI contains additional control information from the Tx UE to the Rx UE for the sidelink V2X communication. The Rx UE decodes the second-stage SCI using at least in part an identifier which identifies the Rx UE as a destination of the received signal.

Abstract: For sidelink vehicle-to-everything (V2X) transmission, a first user equipment (UE) obtains time-and-frequency resources that are bounded by two subchannel boundaries and two slot boundaries. The first UE transmits encoded control information to a second UE in a Physical Sidelink Control Channel (PSCCH) that occupies a first portion of the time-and-frequency resources starting from a lowest resource block (RB) in a lowest subchannel and from an earliest symbol available for sidelink control and data transmission. The first UE further transmits encoded data to the second UE in a Physical Sidelink Shared Channel (PSSCH) that occupies a second portion of the time-frequency resources. The second portion includes (a) a first set of RBs in the same symbols as the PSCCH and not used by the PSCCH, and (b) a second set of RBs in symbols not used by the PSCCH.

Abstract: Sidelink vehicle-to-everything (V2X) transmission is performed over a Physical Sidelink Control Channel (PSCCH) and a Physical Sidelink Shared Channel (PSSCH). Encoded control information is transmitted in the PSCCH and encoded data is transmitted in the PSSCH. The PSCCH uses a first portion of the time-and-frequency resources, and the PSSCH uses and a second portion of the time-and-frequency resources. A first part of the PSSCH uses a first set of time resources overlapping with the PSCCH and a first set of frequency resources non-overlapping with the PSCCH. A second part of the PSSCH uses a second set of time resources non-overlapping with the PSCCH and a second set of frequency resources overlapping with the PSCCH.

Abstract: Aspects of the disclosure provide an apparatus that includes transmitting circuit and processing circuit. The transmitting circuitry is configured to transmit wireless signals. The processing circuitry is configured to encode a set of information bits with a code that is configured for incremental redundancy to generate a code word that includes the information bits and parity bits, buffer the code word in a circular buffer, determine a start position in the circular buffer based on a redundancy version that is selected from a plurality of redundancy versions based on a scenario evaluation of a previous transmission associated with the set of information bits, and transmit, via the transmitting circuitry, a selected portion of the code word from the start position.

Abstract: Concepts and schemes pertaining to location of interleaver with low-density parity-check (LDPC) code are described. A processor of an apparatus encodes data to provide a stream of encoded data. The processor also rate matches the encoded data to provide a rate-matched stream of encoded data. The processor further interleaving the rate-matched stream of encoded data. In rate matching the encoded data, the processor buffers the stream of encoded data in a circular buffer, with the circular buffer functioning as a rate matching block that rate matches the stream of encoded data. In interleaving the rate-matched stream of encoded data, the processor performs bit-level interleaving on the rate-matched stream of encoded data to provide a stream of interleaved data.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a transmitting UE. The transmitting UE transmits a reference signal and data to one or more receiving UEs. The transmitting UE receives one or more response signals from the one or more receiving UEs on a particular resource element. Each of the one or more response signals represents at least one of (a) a respective indication based on a measurement at a respective receiving UE, of the one or more receiving UEs, transmitting the each response signal and (b) a respective acknowledgment from the respective receiving UE associated with the data. The transmitting UE determines a transmission power at the transmitting UE based on the respective indications. The transmitting UE transmits data to the one or more receiving UEs at the transmission power.

Abstract: Various novel concepts and schemes pertaining to non-orthogonal multiple access for wireless communications are described. A group orthogonal coded access (GOCA) scheme is introduced to reduce multi-user interference (MUI) and improve performance. A repetition division multiple access (RDMA) scheme is introduced to differentiate user equipment (UEs) by different repetition patterns. A low-density spreading (LDS) scheme is introduced to reduce MUI and improve performance.

Abstract: A method of beam administration in a cellular or wireless network is proposed. Cellular/wireless networks operating at Ka or higher frequency band require the use of directional antenna (or through array-based beamforming) to compensate for sever pathloss. Maintaining antenna pointing and tracking accuracy is essential in many phases of the communication process. By using uplink pilot signals for beam alignment/tracking, combined with switched beamforming at the UE and adaptive beamforming at the BS, an effective beam administration is achieved with reduced overhead, complexity, and cost.
