摘要： Systems and methodologies are described that facilitate reducing false detections of control channels during blind decode when multiple component carriers are configured. A UE can perform blind detection of control channels on a plurality of carriers, wherein each control channel detected can be validated to reduce false detections. In one aspect, a reference carrier can be selected, wherein one or more detected control channels are validated so long as one detected control channel is on the reference carrier. In another aspect, control channel can be bundled such that multiple control channel detections are required for validation. Moreover, dummy control channels can be introduced that provide UE with guidance during blind decoding, as well as provide validation of detections. Further, various combinations of a reference carrier, bundling, and/or a dummy control channel can be utilized.

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： Systems and methodologies are described that facilitate cycling through precoders for transmitting wireless network communications in a time domain. The precoders can be cycled according to a precoder sequence for each data symbol transmission. When the last precoder is selected the cycle can begin again, a new precoder sequence can be received or defined, and/or the like. A precoder sequence related to a subset of precoders present in a wireless device can be defined sequentially, cyclically shifted according to an identifier or one or more communications parameters, randomly, pseudo-randomly according to an identifier or one or more communications parameters, and/or the like. In addition, the precoder sequence can be utilized to select a precoder for one or more retransmissions. Such cycling of precoders can increase transmit diversity.

摘要： Techniques for performing frequency hopping in a wireless network are described. In an aspect, frequency hopping may be performed based on both cell identity (ID) and system time information. In one design, a user equipment (UE) may determine a cell ID of a cell and may obtain system time information for the cell. The UE may determine resources to use for transmission with frequency hopping based on the cell ID and the system time information. In one design, the UE may initialize a PN generator in each radio frame with an initial value determined based on the cell ID and a system frame number (SFN) for the radio frame. The UE may determine the resources to use for transmission based on a hopping function, a mirroring function, and a PN sequence from the PN generator. The UE may send a transmission on the resources to the cell.

摘要： Techniques for controlling the operation of user equipments (UEs) to mitigate emissions out of band are described. A base station may identify a UE potentially causing excessive emissions out of band due to transmission of control information and may schedule the UE to reduce the emissions out of band. In one design, the base station may schedule the UE to send control information on a Physical Uplink Shared Channel (PUSCH) instead of a Physical Uplink Control Channel (PUCCH). In another design, the base station may assign the UE with resources for the PUCCH to send control information. The assigned resources may be selected to mitigate the emissions out of band and may be (i) located within a target frequency range, (ii) located away from a frequency band to be mitigated with the emissions out of band, or (iii) obtained with a reuse scheme and have less inter-cell interference from other UEs.

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： 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.
