METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING SIGNAL IN WIRELESS COMMUNICATION SYSTEM
A UE according to an embodiment of the present disclosure may receive information about a plurality of beta offset values for determining the number of REs for UCI to be transmitted on a PUSCH, receive DCI scheduling a first PUSCH, and transmit a first HARQ-ACK on the first PUSCH, and transmit the first PUSCH. The plurality of beta offset values may include first beta offset values for a case where the priority of the first HARQ-ACK is identical to the priority of the first PUSCH, and second beta offset values for a case where the priority of the first HARQ-ACK is different from the priority of the first PUSCH.
SELECTING MODULATION AND CODING SCHEME
A modulation and coding scheme for a transmission to an apparatus may be selected by at least sampling a posteriori probability distribution that has been calculated using a first probability distribution and a second probability distribution. The first probability distribution is calculated using at least a newest first feedback and a plurality of older first feedbacks, a first feedback indicating channel quality. The second probability distribution is calculated using at least a newest second feedback and a plurality of older second feedbacks, a second feedback indicating a success or failure of an earlier transmission transmitted from the apparatus.
Group acknowledgement/negative acknowledgement and triggering GACK/channel state information
According to the present disclosure, CSI and/or a plurality of ACKs related to a group of DL data transmissions may be buffered at the UE as a GACK until a DCI trigger is received from the eNB. Once the trigger is received, the UE may transmit the CSI and/or GACK to the eNB. In this way HARQ feedback and/or CSI may be reliably communicated while reducing payload. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus send, to a UE, data transmissions associated with a first plurality of downlink subframes. In an aspect, the apparatus increments a counter for each data transmission sent to the UE. In a further aspect, the apparatus transmits, to the UE, a first trigger for a first GACK when a counter is greater than or equal to a threshold.
Priority-based hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink data from a base station. The UE may transmit, to the base station via a physical uplink control channel (PUCCH) format 1 and based at least in part on the downlink data, a first hybrid automatic repeat request acknowledgement (HARQ-ACK) bit associated with a high priority using a first quantity of symbols. The UE may transmit, to the base station via the PUCCH format 1 and based at least in part on the downlink data, a second HARQ-ACK bit associated with a low priority using a second quantity of symbols that is less than the first quantity of symbols. Numerous other aspects are provided.
Lossy Compressed Feedback For Multiple Incremental Redundancy Scheme (MIRS)
Various embodiments may provide systems and methods for supporting lossy compression of feedback information, such as acknowledgment (ACK) information, negative acknowledgement (NACK) information, etc. Various embodiments may support lossy compression for feedback messages in retransmission systems, such as Hybrid Automatic Repeat Request (HARD) protocols, the Multiple Incremental Redundancy Scheme (MIRS), etc. Various embodiments may support compression of feedback bits using a different compression codebook per symbol or per group of symbols. Various embodiments may support selection of a compression codebook per symbol, or per group of symbols, based at least in part on a probability of successful decoding of each code block in the symbol or group of symbols.
FEEDBACK SIGNALING FOR WIRELESS COMMUNICATION
There is disclosed a method of operating a wireless device in a wireless communication network, the method comprising transmitting feedback signaling including feedback information, the feedback information being encoded with an error coding scheme, wherein an error coding size of the error coding scheme is dependent on a type of the feedback information.

Device and method for reliable classification of wireless signals
A machine learning (ML) agent operates at a transmitter to optimize signals transmitted across a communications channel. A physical signal modifier modifies a physical layer signal prior to transmission as a function of a set of signal modification parameters to produce a modified physical layer signal. The ML agent parses a feedback signal from a receiver across the communications channel, and determines a present tuning status as a function of the signal modification parameters and the feedback signal. The ML agent generates subsequent signal modification parameters based on the present tuning status and a set of stored tuning statuses, thereby updating the physical signal modifier to generate a subsequent modified physical layer signal to be transmitted across the communications channel.
