摘要： Aspects describe utilizing a dedicated reference signal for supporting Network MIMO, distributed MIMO, Coordinated MultiPoint, and the like. A data modulation symbol is transmitting in the same direction as a pilot modulation symbol is transmitted. Two or more wireless devices can coordinate communications such that transmission of the same pilot modulation symbol and the same data modulation symbol are transmitted to a device in different directions, each direction associated with a wireless device and intended for a particular mobile device. Cluster-specific scrambling and/or user-group specific scrambling can be employed and a scrambling code can be communicated prior to transmission of the pilot modulation symbols and data modulation symbols.

摘要： Embodiments disclosed herein relate to providing effective interference control in a wireless communication system. In one embodiment, a method for determining an interference level in a wireless communication system is described, including: determining a rise-over-thermal (RoT) metric based on an RoT received at each receiver antenna of an access network, the RoT relating to a ratio of a total energy to a thermal energy received at each receiver antenna; determining an interference-reduction factor (p) in relation to an interference energy reduced from the total energy received at each receiver antenna; and determining an effective rise-over-thermal (RoT eff ) based on the RoT metric and the interference-reduction factor, the RoT eff relating to the interference level in the wireless communication system. The method may further include comparing the RoT eff with a threshold and relating the result of the comparison (e.g., the sector loading status) to each access terminal in communication with the access network.

An exemplary method generally includes determining a mother code size (N) for transmitting an encoded stream of bits based, at least in part, on a minimum supported code rate for transmitting the encoded stream of bits (R min ), a control information size of the encoded stream of bits (K), a number of coded bits for transmission (E), and a maximum mother code size (N max ), encoding a stream of bits using a polar code of size (N, K) and storing the encoded stream of bits in a circular buffer, and performing rate-matching on the stored encoded stream of bits based, at least in part, on a comparison among the mother code size (N), the control information size of the encoded stream of bits (K), and the number of coded bits for transmission (E).

摘要： Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to methods and apparatus for dynamic frozen polar codes, for example, for control channels. An exemplary method may be performed at the encoder. The method generally includes encoding a stream of bits using a polar code. The encoding includes selecting a first set of channel indices for encoding information bits. The encoding includes selecting a second set of the channel indices smaller than a channel index for a first information bit for encoding fixed frozen bits. The encoding includes selecting remaining channel indices for dynamic frozen (PCF) bits having values based on one or more of the information bits. The method includes transmitting the encoded stream of bits.

摘要： Wireless communication devices are adapted to employ Golay-based matrices for encoding a wireless transmissions. According to at least one example, a wireless communication device can identify an information vector to be transmitted as a wireless communication. A Golay-based generator matrix may be selected based on a length of the information vector, where the selected Golay-based generator matrix is generated by shortening a Golay generator matrix by removing a plurality of columns of systematic bits and a plurality of rows to obtain the shortened generator matrix, and extending the shortened generator matrix to obtain an extended generator matrix by adding columns to at least the systematic bits and appending rows to obtain a desired matrix size. A respective bit value may be determined for bits in each added column and for at least some of the bits in each appended row. Other aspects, embodiments, and features are also included.
