Abstract: A wireless device receives downlink control information (DCI) scheduling a physical uplink shared channel (PUSCH) transmission. The wireless device transmits, based on the DCI not comprising a sounding reference signal (SRS) resource indicator (SRI) field, the PUSCH transmission: in one or more first occasions associated with a first SRS resource set, with a first transmission power determined based on a first closed-loop index equal to zero, and in one or more second occasions associated with a second SRS resource set, with a second transmission power determined based on a second closed-loop index equal to one.

Abstract: A method for transmitting data based on grant-free uplink scheduling. The method is performed by a terminal. The method includes: listening, based on a first listening parameter, an acknowledgement on uplink data from a base station, during a process of transmitting the uplink data based on a target number of repeat transmissions through a grant-free uplink scheduling mechanism, the acknowledgement being configured to indicate a successful reception of the uplink data; and terminating transmitting the uplink data in response to that the acknowledgement is listened before a completion of transmitting the uplink data based on the target number of repeat transmissions.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a starting symbol of a radio frequency (RF) retuning gap between a first plurality of repetitions of an uplink transmission in a first frequency hop and a second plurality of repetitions of the uplink transmission in a second frequency hop. The starting symbol of the RF retuning gap is based at least in part on a starting symbol of the second plurality of repetitions and a quantity of symbols included in the RF retuning gap. The UE may determine an ending symbol of the RF retuning gap based at least in part on the starting symbol of the second plurality of repetitions. The UE may perform RF retuning during the RF retuning gap. Numerous other aspects are provided.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for PUCCH/PUSCH DMRS bundling. A UE may transmit, to a network entity, a first indication of a maximum DMRS bundling duration for maintaining transmit phase coherence for transmitted DMRS. The UE may receive, from the network entity based on the first indication of the maximum DMRS bundling duration, a second indication of at least one of a DMRS bundling activation or a DMRS bundling duration. Based on the at least one of the DMRS bundling activation or the DMRS bundling duration, the UE may transmit at least one UL repetition including bundled DMRS.

Abstract: A wireless communication device and a communication method for header repetition are described. The device and method receive and decode a wireless packet through a communication channel. Formats of the wireless packet includes a first packet format and a second packet format. In this regard, the first packet format comprises a first header field carried by a first orthogonal frequency division multiplexing (OFDM) symbol while the second packet format comprises both the first header field carried by the first OFDM symbol and a second header field carried by a second OFDM symbol which follows the first OFDM symbol. The second header field is a repetition of the first header field. According to an exemplary embodiment, the second packet format is distinguished from the first packet format by detecting, from the received wireless packet, the second header field which repeats the first header field.

Abstract: An encoder outputs a first bit sequence having N bits. A mapper generates a first complex signal s1 and a second complex signal s2 with use of bit sequence having X+Y bits included in an input second bit sequence, where X indicates the number of bits used to generate the first complex signal s1, and Y indicates the number of bits used to generate the second complex signal s2. A bit length adjuster is provided after the encoder, and performs bit length adjustment on the first bit sequence such that the second bit sequence has a bit length that is a multiple of X+Y, and outputs the first bit sequence after the bit length adjustment as the second bit sequence. As a result, a problem between a codeword length of a block code and the number of bits necessary to perform mapping by a set of modulation schemes is solved.
