摘要： Methods, systems, and devices for wireless communication are described. A transmitter may generate a first segmentation based on a first subset of control information and a second segmentation based on jointly encoding the first subset and a second subset of the control information. The transmitter may polar encode the first segmentation to generate a first codeword and the second segmentation to generate a second codeword, and transmit the first and second codewords. A receiver may determine a first bit sequence corresponding to the first subset based on decoding a first codeword and determine an error detection code (EDC) and a second bit sequence corresponding to the second subset based on decoding a second codeword. The receiver may perform error detection on the first and second bit sequences based on the determined EDC, and output the first bit sequence and the second bit sequence or a decoding error.

摘要： The disclosure relates in some aspects to information encoding. Information encoding may involve puncturing bits of a codeword or repeating bits of a codeword. The disclosure relates in some aspects to selecting a puncturing or repetition pattern. In some aspects, a puncture pattern for data encoding is selected based on a criterion that the output and the repetition input of an XOR are not erased. In some aspects, a repetition pattern for data encoding is selected based on a criterion that repetition not be applied for the output and the repetition input of an XOR.

摘要： Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to methods and apparatus for rate-matching control channels using polar codes. An exemplary method generally includes encoding a stream of bits using a polar code, determining a size of a circular buffer for storing the encoded stream of bits based, at least in part, on a minimum supported code rate and a control information size, and performing rate-matching on stored encoded stream of bits based, at least in part, on a mother code size, N, and a number of coded bits for transmission, E.

摘要： Methods, systems, and devices for wireless communication are described for dynamic frozen bits of polar codes for early termination and performance improvement. A wireless device may receive a signal comprising a codeword encoded using a polar code. The wireless device may perform decoding of the codeword including at least: parity check of a first subset of decoding paths for making a decision on early termination of decoding of the codeword based on dynamic frozen bits, and generating path metrics for a second subset of the decoding paths that each pass the parity check based on the dynamic frozen bits, and performing error detection on a bit sequence corresponding to one of the second subset of the decoding paths based at part on error detection bits and the generated path metrics. The wireless device may process the information bits based on a result of the decoding.

摘要： Synchronization of uplink carriers for transmission is disclosed in accordance with different aspects. The uplink carriers that transmit information are configured such that at least one of the uplink carriers is an anchor carrier. When a plurality of carriers are thus configured for the uplink, they are synchronized such that they bear a predetermined phase relationship with each other. The predetermined phase relationship between the plurality of carriers depends on the transmit timing of the anchor carrier or a combination of transmit timings of the anchor carrier and one or more non-anchor carriers comprised within the uplink carriers.

摘要： A method, an apparatus, and a computer program product for wireless communication are provided in which VoIP traffic is scheduled in a way that focuses on controlling user latencies, by reshaping packet latency profiles of individual users to more efficiently utilize power/code resources. A feedback mechanism may utilize certain latency controllers to adjust a queuing delay and an over-the-air transmit time to meet latency targets. That is, system resources may be allocated in a wireless network by adjusting a latency target for a packet responsive to a user's packet latency history.
