摘要： A method performed by a wireless transmitter determining a transport block size (TBS) is provided. The method includes determining a TBS using a general function of a number of physical resource blocks (PRBs) to be granted (N_PRB), a number of resource elements (REs) per PRB (N_RE{circumflex over ( )}(DL,PRB)), a number of layers per transport block (υ), a number of bits per modulation (Q_m), and a coding rate determined by a modulation coding scheme (MCS) (R), allocating a transport block of the determined TBS and transmitting the transport block to a wireless receiver. Apparatuses for implementing the method are also provide.

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 using a high order modulation (HoM) mode for communications with a wireless device in a wireless communication network is provided. The method includes receiving downlink channel quality indicator (CQI) information from an uplink transmission of the wireless device and determining a downlink channel quality estimate from the CQI information. When a measurement of the downlink channel quality estimate satisfies the predetermined criteria for a first predetermined number of consecutive uplink transmissions from the wireless device, a downlink transmission mode of the wireless device is switched from a first modulation mode to the HoM mode.

摘要： According to some embodiments, a method for polar encoding includes obtaining an input bits index array Q, wherein each element Q[i] is an index of a polar coded transmission channel and corresponds to an input U[i] of a polar encoder. The elements of Q are ordered according to their associated channel quality. The method further includes obtaining an integer number X of bits for polar encoding and wireless transmission, wherein X is not greater than N. Upon determining the polar code block length N is not greater than the number of rate matched bits M available for transmission, the method includes assigning each of the bits as inputs to the polar encoder ordered according to the input bits index array Q.
