Abstract: Signaling methods for UE-specific downlink control channels in OFDMA systems are provided. In a first method, a dynamic downlink signaling in cell-specific radio resources is used to signal UE-specific downlink control channel in UE-specific radio resources. In LTE, a specific DCI format in PDCCH is used to dynamically signal the UE-specific downlink control channel X-PDCCH that resides in legacy PDSCH region. In a second method, a semi-static higher-layer signaling is used to signal UE-specific downlink control channel in UE-specific radio resources. In LTE, RRC signaling is used to semi-statically signal the UE-specific downlink control channel X-PDCCH that resides in legacy PDSCH region. By using UE-specific downlink control channels, significant control overhead reduction can be achieved.

Abstract: A method of determining priority rules for periodic CSI reporting in carrier aggregation is proposed. A UE obtains channel state information (CSI) feedback for multiple downlink component carriers (CCs) in a multi-carrier wireless communication network. Each downlink CC is associated with a feedback mode, and each feedback mode comprises a set of feedback types to be reported to a base station at time slots configured by an upper layer. The UE then determines a prioritized downlink CC for CSI reporting based on priority levels of the feedback types to be transmitted for each downlink CC at a given time slot. The UE then transmits the corresponding CSI feedback for the prioritized downlink CC at the given time slot via a feedback channel over a primary uplink CC. In one embodiment, different feedback types are prioritized by groups, and each group has several feedback types sharing the same priority.

Abstract: A method of multi-set RRC signaling for ap-SRS configuration is provided to enhance ap-SRS flexibility. An eNB transmits a plurality of sets of UE-specific SRS parameters to a UE via upper layer messaging in a multi-carrier wireless communication system. The eNB also determines triggering information of a selected set of UE-specific SRS parameters and an indicated carrier for the UE. The eNB then transmits an uplink or downlink grant over a primary carrier, the grant comprises triggering information for the UE to send an ap-SRS over the indicated carrier using the selected set of UE-specific SRS parameters. In one embodiment of joint signaling, the plurality of sets of UE-specific SRS parameters are signaled together in a single RRC transmission. In another embodiment of separate signaling, each set of UE-specific SRS parameters is signaled independently.

Abstract: Sounding mechanism for LTE-A systems under carrier aggregation is provided. A UE receives an uplink or downlink grant transmitted from an eNB over a primary carrier in a multi-carrier LTE-A system. The UE determines indicated carrier(s) and detects a triggering condition for aperiodic sounding transmission in the grant. The UE then selects UE-specific sounding reference signal (SRS) parameters. Finally, the UE transmits an aperiodic SRS (ap-SRS) over the indicated carrier(s) using the selected UE-specific SRS parameters. In one embodiment, the uplink or downlink grant is transmitted via a PDCCH carrying various DCI formats. Each DCI format contains a carrier indicator field (CIF) that indicates which carrier is used for ap-SRS transmission if cross-carrier scheduling is enabled. In another embodiment, DCI format 3/3A is transmitted via a PDCCH carrying a plurality of information fields, each field indicates if the UE should enable ap-SRS in a particular carrier.

Abstract: A method for contention-based (CB) uplink transmission in a wireless communication network is provided. A base station (eNB) first transmits CB configuration information and CB grant to a user equipment (UE). The UE derives a plurality of transmission opportunities from the uplink CB grant and in response transmits uplink CB data via one of the transmission opportunities. The UE then receives an acknowledgment from the serving base station. If the uplink CB data is non-decodable by the eNB due to multiple contention UEs, then the UE retransmits the uplink data in response to a negative acknowledgment. In one novel aspect, the uplink transmission radio resource carriers both the uplink CB data and UE-selected signature information. In one embodiment, the UE-selected signature information is transmitted via pilot tones. By eliminating a separate phase of contention resolution, the overall latency of CB transmission is reduced and transmission efficiency is improved.

Abstract: A method of multi-antenna resource allocation for uplink channel sounding in a wireless communication system is provided. A base station (eNB) first selects a number of sounding reference signal (SRS) parameters. The eNB then determines each selected SRS parameter for a first antenna of a user equipment (UE) having multiple antennas. The determined parameters are jointly encoded to a first set of parameter combination using a number of signaling bits. The eNB transmits the signaling bits for the first antenna to the UE without transmits additional signaling bits for other antennas. The UE receives the signaling bits for SRS resource allocation for the first antenna and derives a second set of parameter combination for a second antenna based on a predetermined rule. By implicitly signaling SRS resource allocation for multiple antennas, it is easy for the eNB to allocate SRS resource for different antennas of different UEs with reduced overhead.

Abstract: A method of resource allocation for uplink channel sounding in a wireless communication system is provided. A base station (eNB) first selects a number of sounding reference signal (SRS) parameters. The eNB then determines a deviation set for each selected SRS parameter and jointly encodes the selected number of SRS parameters using a number of signaling bits. The signaling bits are transmitted to a user equipment (UE) for uplink channel sounding. Based on system requirements, some parameter combinations are filtered out and only necessary parameter combinations are jointly encoded such that the number of signaling bits is limited to a predefined number. In one embodiment, the signaling bits are contained in downlink control information (DCI) via a physical downlink control channel (PDCCH) for triggering Aperiodic SRS (ap-SRS). By jointly encoding selected SRS parameters, the eNB can dynamically configure ap-SRS parameters and resources for each UE with high flexibility and efficiency.

Abstract: A method of concatenating precoder selection is provided for OFDMA-based multi-BS multiple-input multiple-output (MIMO). A cell-edge mobile station first determines a precoding matrix indexes (PMIs) for a serving base station and one or more cooperative base stations to optimize system performance. The mobile station then determines a plurality of corresponding weight factors for each of the base stations to further optimize system performance.

Each base station then applies precoding using the recommended PMIs and weight factors. The weight factors are quantized to reduce computation complexity and to facilitate information feedback. In one embodiment, the weight factors are determined based on a pre-defined 3-bit uniform phase quantization rule.

Abstract: A method for broadcasting system information via a broadcast channel (BCH) in an OFDMA system is provided. The BCH comprises one or more two-dimensional resource blocks. A plurality of pilot tones and a plurality of data tones are positioned within each resource block. The system information is mapped onto the plurality of data tones. In one embodiment, the plurality of pilot tones are located in configurable positions such that pilot tones of the same resource blocks transmitted by different base stations in the OFDMA system are interlaced to reduce pilot-to-pilot collision. In another embodiment, data tones that are located in pilot positions of other adjacent cells are nullified to reduce data-to-pilot collision. In one novel aspect, the property of interlaced pilot patterns and tone nullification is leveraged to estimate interference second-order statistics, which facilitates receiver implementation and improves receiver performance.

Abstract: In wireless OFDMA systems, sounding channels are allocated within predefined resource blocks. In a distributed sounding channel allocation scheme, a sounding channel is allocated to meet various design considerations. First, sounding signals do not collide with original pilots transmitted in the same resource block by other mobile stations to achieve good quality channel estimation. Second, sounding pattern does not affect data transmission behavior of other mobile stations in the same resource block. Third, sounding pattern consistency among multiple tiles within each resource block is maintained so that mobile stations do not need to implement additional data mapping rules. In a symbol-based sounding channel allocation scheme, a sounding channel is allocated in the first or the last OFDM symbol of a resource block, while the remaining consecutive OFDM symbols are used for data transmission. The symbol-based sound channel naturally satisfies all design considerations.
