Abstract: PROBLEM TO BE SOLVED: To provide techniques for transmitting traffic data and control information in a wireless communication system.SOLUTION: Traffic data and control information are multiplexed at a coded data level. User equipment (UE 120) encodes the traffic data to obtain coded traffic data, encodes the control information to obtain coded control data, multiplexes the coded traffic data and the coded control data, modulates the multiplexed data, and generates SC-FDMA symbols. In addition, the traffic data and the control information may be multiplexed at a modulation symbol level. The UE performs rate matching for the traffic data to correspond to the control information. The UE also performs multiplexing and puncturing for different types of control information.

Abstract: PROBLEM TO BE SOLVED: To reduce inter-cell interference with a more efficient method.SOLUTION: Inter-cell interference is mitigated using joint time and frequency division. A frequency band is divided into multiple non-overlapping frequency subbands. A transmission timeline is divided into Tand Ttime intervals. Data is exchanged with users in at least one inner region of a cell on the entire frequency band in the Ttime intervals. The data is exchanged with users in multiple outer regions of the cell on the multiple frequency subbands in the Ttime intervals. The frequency band may be divided into three frequency subbands. The data may then be exchanged with users in first, second and third outer regions on first, second and third frequency subbands, respectively. The regions in which the users are located may be determined based on pilot and/or other measurements.

Abstract: PROBLEM TO BE SOLVED: To provide techniques for accessing a wireless communication system.SOLUTION: User equipment (UE) sends a random access preamble including a random identifier (ID), a channel quality indicator (CQI), etc. The UE randomly selects the random ID, or this random ID is assigned to the UE. The UE receives a random access response from a base station. The random access response includes control channel resources (CQI and PC resources), uplink resources, and control information (timing advance and PC correction) for the UE. The random access response is sent in two parts using two messages. A first message may include identification information and other information on a control channel. A second message may be sent on a shared data channel and may include remaining information for the random access response.

Abstract: PROBLEM TO BE SOLVED: To provide systems and methods for transmitting simultaneously a first and a second communication channel in a single-carrier waveform format with disparate error rate requirements.SOLUTION: A first channel and a second channel are coded individually to form an alphabet for a first constellation and a second constellation. Prior to transmission, bits of information of the first and second channels are modulated with a hierarchical modulation constellation generated through composition of the first and second constellations. Each constellation is assigned a configurable weight (e.g., a "hierarchic weight") that is expressed in terms of a configurable energy ratio. The energy ratio determines the resilience of bits associated with the first and second channels. The first and second constellations provide redundancy to mitigate an error rate within each quadrant of the hierarchical constellation. Hierarchical modulation of more than two channels can be accomplished through the same principal of individual coding and constellation composition.

Abstract: PROBLEM TO BE SOLVED: To increase spectral efficiency of a cellular single frequency network using Multiple-In Multiple-Out (MIMO) techniques.SOLUTION: Multiple data streams, in one data stream per set of transmit antennas, are transmitted from multiple cells. A mapping of the streams to the antenna sets is permuted temporally. In this way, user equipment devices (UEs 140) at cell edges benefit from the MIMO, and UEs near cell centers benefit from a high carrier-to-interference (C/I) ratio of a signal. Each stream is concurrently transmitted on a base layer of a hierarchically modulated signal from one set, and on an enhancement layer of the hierarchically modulated signal from another set. A mapping of the sets to the streams is permuted temporally. The UEs at the cell edges benefit from the MIMO, and the UEs near the cell centers benefit from the high C/I to decode both streams from the base and enhancement layers.

Abstract: PROBLEM TO BE SOLVED: To provide techniques for quickly and efficiently performing handover.SOLUTION: UE may maintain uplink synchronization with one or more non-serving cells in a candidate set, without having to maintain links with any of the non-serving cells. The UE may update uplink synchronization with the non-serving cells via an access procedure, e.g., send access probes to the non-serving cells and receive timing adjustments from these cells. One non-serving cell with which the UE has maintained uplink synchronization may be selected as a target cell for handover. The UE may then perform handover from the serving cell to the target cell, without performing uplink synchronization during the handover, which may improve handover latency and success rate.
