摘要： Methods of performing link adaptation in a wireless communication system for simultaneous transmission of codewords include selecting initial modulation and coding scheme (MCS) levels for the codewords, estimating a size ratio of the codewords, determining a number of scheduling blocks (SB) for the codewords with the initial MCS levels, and determining revised MCS levels for the codewords in response to the determined number of SBs. Transport block sizes are computed for the codewords, and it is determined if there is a need to increase the number of scheduling blocks in at least one of the codewords. If there is a need to increase the number of scheduling blocks in a codeword, scheduling blocks are added to the codeword, and the transport block size for the codeword is recomputed. The codewords are then simultaneously transmitted over different multiple input-multiple output (MIMO) communication channels using the same time and frequency resources.

摘要： Methods and apparatus are disclosed for allocating PUCCH resources for HARQ feedback so as to minimize the total number PUCCH resources that are allocated while avoiding resource collision. A base station (20) in an uplink Pcell allocates resource sets for use by a plurality of user terminals (25) for providing HARQ feedback to support downlink transmissions to the user terminals (25) in the same transmission time interval. The base station (20) configures a resource group for each user terminal (25). Each resource group comprises a predetermined number of the allocated resource sets. The base station (20) sorts the user terminals (25) in the order of priority from highest to lowest and selects, in order of priority, a resource set for each user terminal (25) from its configured resource group. To select resources for the user terminal (25), the base station (20) calculates a weight for each resource set available to the user terminal (25), and allocate an available resource set with minimum weight to the user terminal (25).

摘要： A method and apparatus is provided for assigning resources for an acknowledgement channel, such as the PHICH in LTE systems. Acknowledgement channels for the mobile terminals are assigned to channel groups based on a predetermined assignment criteria. All acknowledgment channels in the same channel group receive acknowledgements on the same downlink resources (e.g., resource elements in OFDM system). A required transmit energy for each channel is determined. If the total required transmit energy for all channels exceeds an available transmit power, the allocated transmit energy for each channel is either scaled down so that the total actual transmit power for all acknowledgment channels is equal to the available transmit power, or some acknowledgment channels are not transmitted..

In one example, a method comprises selecting trigger states from candidate trigger states, configuring the selected trigger states, and triggering Channel State Information (CSI) reports for the trigger states. In one example, the selected trigger states comprise trigger states that are less than or equal to a maximum number of trigger states supported by the wireless communication device. The candidate trigger states comprises trigger state 0 for a first CSI report for a mixed interference scenario, trigger state 1 for a second CSI report for a non-mixed interference scenario, and trigger state 2 for the first and the second CSI reports.
