摘要： Techniques are described herein to terminate a list decoding operation before its completion based on performing one or more error check processes. A transmitted codeword encoded using a polar code may include one or more error check vectors interspersed with one or more information vectors. Upon receiving the codeword, a decoder may perform a list decoding operation on the received codeword. Upon decoding one of the error check vectors, the decoder may determine whether at least one candidate path used in the successive cancellation list decoding operation passes an error check process based on the error check vector. If no candidate paths satisfy the error check process, the decoder may terminate the list decoding operation. In some examples, the decoder may recheck whether candidate paths satisfy the error check operation at intermediate positions between error check vectors. Such rechecking may occur while decoding information vectors.

摘要： Size ambiguity and false alarm rate reduction for polar codes. A user equipment (UE) may determine a decoding candidate bit sequence for a polar-encoded codeword having a codeword size based on a decoding hypothesis for control information having a particular bit length of multiple different bit lengths for the codeword size. The UE may calculate an error detection code (EDC) value for a payload portion of the decoding candidate bit sequence using an EDC algorithm, and may initialize an EDC variable state with at least one non-zero bit value. Scrambling or interleaving of bits may also be performed prior to, or after, polar encoding and may depend on the bit length. In examples, information bits may be bit-reversed prior to generating an EDC value. In examples, the encoded bits may include multiple EDC values to assist the UE in performing early termination and to reduce a false alarm rate.

The guard band signal includes a symbol that is repeated a number of times equal to the multiple. The guard band signal may be generated and transmitted by a transmitting device. The guard band signal may be received and decoded by a receiving device. The guard band signal is interpretable according to a first numerology of the first radio access technology and according to a second numerology of the second radio access technology.

摘要： Aspects of the present disclosure relate to wireless communication devices and methods configured to operate with multiple communication protocols in tune-away operations. Some aspects of the present disclosure may improve the legacy tune-away operations at an access terminal. An access terminal establishes a call utilizing a first communication protocol, tunes away from the call to receive cell signaling utilizing a second communication protocol, and tunes back to the call utilizing the first communication protocol. Following the tuning back, during a first predetermined number of subframes and if the size of a reverse link (RL) packet is smaller than a first packet size and larger than a second packet size, the access terminal forces the RL packet to be a low latency (LoLat) packet.

摘要： The various embodiments include a dual-SIM-dual-active (DSDA) device and methods for implementing robust receive (Rx) processing to resolve radio frequency coexistence interference between two subscriptions operating on the DSDA device. The DSDA device may detect when a subscription (the “aggressor”) de-senses the other subscription (the “victim”) as a result of the aggressor's transmissions, and in response, implement robust Rx processing to mitigate the effects of de-sense on the victim while causing minimal impact to the aggressor.

摘要： A method, an apparatus, and a computer program product are provided. The apparatus may be configured to establish a first call for a first subscription, and accept a second call for a second subscription while maintaining the first call. A single RF transmit chain may be scheduled for uplink transmissions associated with the first call and uplink transmissions associated with the second call. A timesharing schedule for the transmit chain may determine timing for the uplink transmissions associated with the first call is transmitted and when the uplink transmissions associated with the second call is transmitted on the transmit chain. Downlink transmissions associated with the first and second calls may be received using different receive chain. Downlink transmissions associated with the first and second calls may be received using the same receive chain.
