摘要： Techniques for handling inconsistent control information in a wireless communication system are described. In an aspect, inconsistent control information is handled in different manners for the downlink and uplink. In one design, a user equipment (UE) receives a first grant with first control information for a first data transmission and also receives a second grant with second control information for a second data transmission. The UE determines that the second control information is inconsistent with the first control information, e.g., due to the two grants conveying different transport block sizes. The UE determines whether to retain or discard the second grant based on whether the two grants are for data transmissions on the downlink or uplink. In one design, the UE retains the second grant if the two grants are for data transmissions on the downlink and discards the second grant if the two grants are for data transmissions on the uplink.

摘要： Techniques for sending feedback information for multi-carrier operation are described. In an aspect, feedback information may be sent on an uplink carrier that may or may not be paired with a downlink carrier on which data transmission is sent. A user equipment (UE) may receive data transmission on a downlink carrier among a plurality of downlink carriers. The UE may determine feedback information for the data transmission, determine an uplink carrier to use to send the feedback information from among a plurality of uplink carriers, and send the feedback information on the uplink carrier. In another aspect, feedback information for multiple downlink carriers may be sent on at least one uplink carrier using Single-Carrier Frequency Division Multiple Access (SC-FDMA). A UE may receive data transmissions on a plurality of downlink carriers, determine feedback information for the data transmissions, and send the feedback information on at least one uplink carrier using SC-FDMA.

摘要： A method is provided to allocate resources for wireless communications. The method includes grouping downlink control channels from multiple subframes and ordering the downlink control channels across downlink subframes having a first control channel element located in a first symbol map and associated with reserved resources for an uplink channel. The method employs a symbol first mapping or a mixed-symbol/subframe first mapping to efficiently allocate the resources.

摘要： Different sequence resources can be allocated to a mobile device where the mobile device can exclusively uses the sequence resource with regard to a base station during a communication session. However, if another mobile device using another base station is assigned a matching sequence resource, then there can be interference if the mobile devices are relatively close enough together. Therefore, randomization of the sequence resources can take place—moreover, a cyclic shift result can be employed in sequence resource allocation to attempt to minimize interference.

摘要： Solutions to problems from delays in channel acquisition by UEs in a contention-based shared radio frequency spectrum band are disclosed. For example, if an eNB knows of a recent or ongoing downlink transmission on a frequency to be used for uplink transmission by a UE, then the eNB may instruct the UE to either skip performance of LBT on that frequency or else perform a type of LBT that is shorter in duration than a full CCA. One way for the eNB to instruct the UE in this fashion is to set an indicator in an uplink grant transmitted to the UE on another frequency. Additionally, in order to avoid truncation of an uplink transmission opportunity, an eNB may notify a UE that an uplink grant is valid for more than one starting point.
