摘要： The present disclosure discloses a processing method and system, configuring method, and demodulating method of demodulate reference signal, a base station and a UE. The base station configures common reference signals on control symbols and user-dedicated reference signals on service symbols; the UE demodulates control information by using the common reference signals and demodulates service data and broadcast data by using the user-dedicated reference signals, wherein the control symbols are OFDM symbols carrying the control information, and the service symbols are OFDM symbols without carrying the control information. With the application of the present disclosure, the purpose of reducing the overhead of reference signals can be achieved.

摘要： Methods and apparatus are provided for selecting a code type. A type of code is selected from a set of code types to use as an inner code for a concatenated encoding scheme for encoding information bits of a channel, wherein the selection is based on one or more channel coding parameters including a false alarm detection objective for the channel. A codeword is generated by encoding the information bits using the type of codes selected as the inner code and an outer code. The generated codeword is transmitted.

摘要： Methods, systems, and devices for wireless communications are described. An encoder of a wireless device may receive a transport block (TB) for transmission and segment the transport block into a set of multiple, smaller data segments that respectively In correspond to a plurality of code blocks of the TB. The encoder may generate a code block level (CB-level) error detection code (EDC) for a subset of the data segments. The encoder may generate a transport block-level (TB-level) EDC for the TB using the data segments. Each of the code blocks (CBs) may be of the same size and may include one of the data segments. A subset of the CBs may include a data segment from the subset of the data segments and one of the CB-level EDCs. The remaining CBs that are not part of the subset may include a remaining data segments and the TB-level EDC.

摘要： A transmitting device may identify a set of bit locations of a polar code for encoding an input vector based at least in part on a reliability order of the bit locations, where the input vector includes a set of payload bits. The transmitting device may map bits of the input vector to respective bit locations of the identified set of bit locations and may apply a masking operation to a subset of bits of the input vector that is mapped to a most reliable subset of the set of bit locations. The transmitting device may perform an encoding operation according to the mapped input vector to generate a codeword for transmission. A receiving device may perform complementary operations to obtain the payload bits of the input vector. Based on the described techniques, a false alarm rate for the receiving device may be suppressed.

摘要： Methods, systems, and devices for wireless communications are described. A transmitting device, such as a base station or a user equipment (UE), may generate a first set of encoded bits using a polar code. The transmitting device may transmit the first set of encoded bits to a receiving device, but the receiving device may unsuccessfully receive the transmission. The transmitting device may prepare a retransmission by generating a second set of encoded bits. In some cases, the transmitting device may copy information bits from the first transmission to polarized channels when generating the polar code for the retransmission. The transmitting device may copy information bits based on how the information bits were assigned for the first transmission as well as the block length. The transmitting device may copy information bits such that the retransmission is self-decodable.

摘要： Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support hybrid automatic repeat request (HARQ) schemes to improve the likelihood that information is received correctly over a wireless communications link. In HARQ, when a transmitting device determines that a receiving device failed to successfully decode a transmission of information, the transmitting device may retransmit the information to the receiving device. In some cases, HARQ techniques may be used for communications associated with different types of services. In such cases, to keep the latency of communications within a latency budget for a particular type of service, wireless devices may utilize the techniques described herein to dynamically terminate HARQ retransmissions. For instance, a transmitting device may avoid retransmitting information when an amount of time that has elapsed since an original transmission of the information has exceeded the latency budget.

摘要： A transmission of information from a secondary to a primary node occurs in a plurality of transmission instances which are logical time durations. A secondary node receives an allocation of periodic transmission instances for a scheduling request indicator (SRI) and an allocation if periodic transmission instances for a sounding reference signal (SRS). In a particular transmission instance allocated for the transmission of both SRS and SRI, the secondary node transmits the SRI without transmitting the SRS if the SRI indicates a pending scheduling request; otherwise, the secondary node transmits the SRS without transmitting the SRI.
