摘要： Techniques for transmitting data from multiple transmit antennas using space orthogonal resource transmit diversity (SORTD) are described. For the SORTD scheme, a different orthogonal resource may be assigned to each transmit antenna. Data may be sent from the multiple transmit antennas using multiple orthogonal resources. In one design, a UE may process at least one information bit (e.g., with joint or independent coding) to obtain first and second sets of at least one modulation symbol. The UE may process the first set of modulation symbol(s) for transmission from the first transmit antenna using a first orthogonal resource. The UE may process the second set of modulation symbol(s) for transmission from the second transmit antenna using a second orthogonal resource. Each orthogonal resource may include a different reference signal sequence or a different set of reference signal sequence and orthogonal sequence.

摘要： Techniques for assigning acknowledgement (ACK) resource to a user equipment (UE) in a wireless communication system are described. In one design, a first parameter indicative of radio resources (e.g., the lowest index of at least one physical resource block) allocated to the UE for data transmission may be obtained. A second parameter indicative of another resource (e.g., a cyclic shift of a reference signal sequence) assigned to the UE for data transmission may also be obtained. The first and/or second parameter may be restricted, and each restricted parameter may be limited to a set of allowed values among all available values for the parameter. ACK resource assigned to the UE for data transmission may be determined based on the first and second parameters. In one design, sequential first parameter values may be mapped to sequential ACK resources indices. In another design, mirror mapping with different mapping directions may be used for different allowed values of the second parameter.

摘要： Systems and methodologies are described that facilitate selecting an uplink carrier for random access within a wireless environment having multiple carriers. Selection of an uplink carrier for random access can be randomly selected from a set of available uplink carriers. Additionally, the uplink carrier for random access can be selected based upon which uplink carrier is paired with an anchor carrier. Further, the uplink carrier for random access can be identified based upon a bandwidth related to the user equipment (UE). Reference signals can also be employed in order to identify an uplink carrier to perform random access.

摘要： Half-duplex (HD) operations enable low cost implementations of LTE terminals. Traditionally, HD operations may be linked to a particular frequency band which may not allow a mix of full-duplex (FD) and HD terminals in the same frequency band. Therefore, certain aspects of the present disclosure provide techniques for enabling coexistence, in a given frequency band, of HD and FD terminals, by introducing frequency bands designated for HD operation and overlapping existing frequency bands designated for FD operation.

摘要： Aspects disclosed herein relate to channel and interference estimations in a multiple transmission point environment including an eNB and RRHs. In the disclosed aspects, one or more transmission points can signal to a UE to measure channel state conditions based on a first and a second resource pattern. The UE may receive the signaling and perform interference estimation based at least in part on the first resource pattern, and channel estimation based at least in part on the second resource pattern. The UE may generate a channel state report based on the interference and channel estimations, and transmit the channel state report to a transmission point. The eNB may employ the received channel state report in scheduling one or more resources for use by the UE, and may select or adjust network traffic on the first and the second resource pattern, to affect the resulting channel and interference estimation.

摘要： A method, an apparatus, and a computer program product for wireless communication are provided in which a first message to reconfigure an uplink transmission mode of a user equipment (UE) from a first uplink transmission mode to a second uplink transmission mode is transmitted. Further, a reconfiguration scheme to assure at least one of two or more second messages are recognizable by the UE during a transition period after transmission of the first message is implemented. In another example, a UE and eNB may be equipped to respectively transmit and receive a first message to reconfigure a SRS mode used by a UE. In such an aspect the first message may respectively indicate and be used to determine an SRS transmission port specified in a field capable of indicating a number of SRS transmission ports that is greater than a number of physical UE antenna ports.

摘要： Methods and apparatuses are provided for determining cyclic shift (CS) values and/or orthogonal cover codes (OCC) for a plurality of demodulation reference signals (DM-RS) transmitted over multiple layers in multiple-input multiple-output (MIMO) communications. A CS index can be received from a base station in downlink control information (DCI) or similar signaling. Based at least in part on the CS index, CS values for the plurality of DM-RSs can be determined. In addition, OCC can be explicitly signaled or similarly determined from the CS index and/or a configured CS value received from a higher layer. In addition, controlling assignment of CS indices and/or OCC can facilitate providing orthogonality for communications from paired devices in multiuser MIMO.
