摘要： A method and system for determining, for a transmission time interval (TTI), an amount of resource units to be allocated to each cell served by at least one module in a wireless communication network are disclosed. The allocation is based on an estimated resource consumption of each cell, a resource limit of each cell and resource limits of the at least one module. For each TTI, a prioritized list of queues having information to be transmitted is determined, where each queue belongs to a cell of the plurality of cells. Also, for each TTI, in an order of priority of the queues, a number of resource units to be consumed by a queue is determined based at least in part on a number of resource units required to empty the queue.

摘要： A radio resource management method is provided. Data for transmission is stored. The stored data is associated with user equipment (UE). A channel quality is estimated. A first modulation and coding scheme (MCS) is determined based at least in part on the estimated channel quality. A first number of scheduling blocks (SBs) required to transmit the stored data is determined based at least in part on the first MCS. The first number of SBs are a minimum of an initial number of SBs and available amount of SBs. A link quality is calculated based at least in part on a channel condition associated with the first number of SBs. A second MCS is determined based at least in part on the calculated link quality and a link quality requirement.

摘要： A method for link adaptation is provided. Data associated with a user device is stored. A first number of scheduling blocks, SBs, required to transmit the stored data is estimated based at least in part on a first modulation and coding scheme (MCS). The first MCS corresponds to a first channel performance level. A second MCS is determined based at least in part on a link quality. The second MCS corresponds to a second channel performance level. A determination is made whether second channel performance level is less than the first channel performance level. An operating MCS is selected based at least in part on whether second channel performance level is less than the first channel performance level. The data is scheduled for transmission based at least in part on the selected operating MCS.

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.
