摘要： Techniques for sending control information relating to multiple downlink carriers and data on a single uplink carrier are described. A user equipment (UE) may be scheduled to transmit on a designated uplink carrier. The UE can multiplex control information for multiple downlink carriers with data for transmission on the uplink carrier in a same subframe. Multiplexing may be performed according to a type of the control information and/or an ordering, priority, or association of the downlink carriers. The UE can selectively encode the control information separately for each downlink carrier and/or jointly across downlink carriers. The control information may be mapped to a single layer or multiple layers of a data channel. The UE may send the multiplexed control information and data on the data channel in the subframe while maintaining a single-carrier waveform.

摘要： Techniques for reliably transmitting and receiving control information in a wireless network are described. A cell may typically send control information on a control channel and associated data (e.g., system information) on a data channel in the same subframe. This subframe may have strong interference from other cells. For cross-subframe signaling, the cell may transmit the control information in a first subframe and the associated data in a second subframe. The first subframe may be a usable subframe for the cell and may have less interference from other cells. A UE may not know the location of the first subframe and may perform window-based decoding. The UE may decode the control channel in at least one subframe within a decoding window covering the first subframe to obtain the control information. The UE may then decode the data channel in the second subframe based on the control information to obtain the data.

摘要： In a method of wireless communication, a UE receives a configuration to receive a CIF for a serving cell of a plurality of serving cells. In addition, the UE monitors a PDCCH on a primary cell of the plurality of serving cells. Said primary cell is different than said serving cell. Furthermore, the UE assumes information received in the PDCCH is for said primary cell when the received information has a common payload size and is in a common search space with a first CCE index in the common search space being equal to a first CCE index in a UE specific search space.

摘要： 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.

摘要： Systems and methods are provided to generate a set of synchronization channel sequences that optimize time and frequency acquisition. A set of root indices of Zadoff-Chu sequences in a first domain (e.g., time domain) that optimize a performance metric or merit factor are identified. An optimal index is determined that also optimizes a performance metric in a reciprocal domain (e.g., frequency domain). For sequences of length Q2=N, a base sequence generated with an optimal sequence can be utilized to generate at least two disparate optimal sequences through sign-flip, conjugation, and periodic modulation operations. Evaluating a primary synchronization channel having length N of 63, an optimal pair of root indices of (28, 31, 32) and (31, 33, 35) provide a five-fold improvement in frequency offset error over conventional single index set of (25, 29, 34).

摘要： Systems and methodologies are described that facilitate controlling interference in a heterogeneous wireless communication environment. A Physical Broadcast Channel (PBCH) transmission from an interfering base station can be punctured based upon a puncturing pattern as a function of a cell identifier (ID) and a transmit time. Puncturing can be effectuated by applying power control. Thus, a punctured symbol or subframe can have a reduced transmit power or a transmit power set to zero. Further, the puncturing pattern can be defined on a subframe basis or on a symbol basis.

摘要： Certain aspects of the present disclosure provide for signaling to expanded capability UEs that may limit the interruption of legacy UEs. According to certain aspects, a base station (e.g., an eNB) may generate and transmit one or more signals containing information that is recognizable by at least one expanded capability UE and identified as invalid by at least one legacy UE. An expanded capability UE may receive such signaling and identifying supplemental information in the signaling, while a legacy UE may regard the signaling as invalid.
