Abstract: according to embodiments of the present disclosure, a solution for supporting repetitions for a plurality of downlink data transmission scheduled by signal downlink control information is proposed. a terminal device receives downlink control information scheduling a plurality of downlink data transmissions with repetitions from a network device. the terminal device determines a harq-ack codebook for the plurality of downlink data transmissions based on a repetition pattern for the plurality of downlink data transmissions and the slot offset. the terminal device transmits a feedback for the repetitions for the downlink data transmissions based on the harq-ack codebook to the network device. in this way, it achieves a flexible repetition patterns for the plurality of downlink data transmissions scheduled by signal dci, which improves the coverage/reliability performance for data transmission.

Abstract: embodiments of the present disclosure relate to methods, devices and computer readable media for communication. a terminal device receives, from a network device, a first timing value set associated with a first harq feedback with a first priority, a second timing value set associated with a second harq feedback with a second priority different from the first priority, and a tdra list for the first and second harq feedbacks, determines a third timing value set from the first and second timing value sets, constructs a harq codebook comprising the first and second harq feedbacks at least based on the third timing value set and the tdra list, and transmits the harq codebook to the network device on an uplink control channel. in this way, unnecessary redundancy in harq bits can be removed and uci overhead can be reduced.

Abstract: estimating determines, on the basis of processed quantized values, a quantization interval for quantizing input element values, which are elements of input values serving as a processing object and determines, on the basis of the processed quantized values, a probability distribution of quantization value candidates, which are candidates of quantized values of the input element values; quantizing uses the quantization interval to quantize the input element values and determine a quantized value; and entropy encoding uses the probability distribution to perform entropy encoding of a quantization time sequence which includes quantized value codes indicating the quantized values of the input element values.

Abstract: embodiments of the present disclosure provide a solution for supporting a successful handover report. in a method for communication, a terminal device receives, from a first network device providing a first cell, an indication that a handover of the terminal device from the first cell to a second cell of a second network device is to be performed. then, the terminal device determines triggering information about a successful handover report of the handover based on a set of triggering conditions. the triggering information indicates whether the successful handover report is triggered for the handover. in this way, the successful handover report can be optionally triggered based on the set of triggering conditions, so that the terminal device may be limited to reporting a successful handover report when necessary, thereby saving processing resources and communication resources for unnecessary successful handover reports.
