摘要： Certain aspects of the present disclosure provide techniques for physical downlink control channel (PDCCH) with repetitions, including techniques for signaling the number of PDCCH repetitions, the hybrid automatic repeat request (HARD) timeline processing with PDCCH repetitions, and the demodulation reference signal (DMRS) structure for the repeated PDCCH. A method for wireless communications, by a user equipment (UE), includes determining a number of repetitions of a PDCCH. Each of the PDCCH repetitions has a same downlink control information (DCI) payload, a same aggregation level, and/or a grant for a same data channel allocation. The method includes monitoring for the PDCCH based on the determined number of repetitions.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may determine to block puncture or to block shorten a set of transmitted bits of an adjusted fractally enhanced kernel polar code for a communication of an incremental redundancy (IR)-hybrid automatic repeat request (HARQ) process based at least in part on a code rate associated with the communication of the IR-HARQ process. The wireless communication device may generate the adjusted fractally enhanced kernel polar code for the communication based at least in part on determining to block puncture or to block shorten the set of transmitted bits. The wireless communication device may transmit the communication using the adjusted fractally enhanced kernel polar code. Numerous other aspects are provided.

摘要： Certain aspects of the present disclosure provide techniques for demodulation reference signal (DMRS) time domain bundling and multiple codeword transmission and processing in new radio (NR) systems. A method by a transmitting device includes transmitting multiple codewords to a receiving device in a first period, each of the multiple codewords transmitted using a different set of one or more DMRS ports. The transmitting device determines to retransmit one or more of the multiple codewords and, for each of the multiple codewords to be retransmitted, the set of DMRS ports for retransmission of the codeword. The determination is based, at least in part, on whether DMRS time domain bundling is configured. The transmitting device retransmits the one or more codewords in a second period based on the determination. The receiving device determines the DMRS ports used and processes the retransmitted codewords based on the determination.

摘要： Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a communication that includes downlink control information (DCI), wherein a size of the DCI affects a cyclic redundancy check (CRC) value associated with the communication; and determine the DCI or the size of the DCI based at least in part on the CRC value. Numerous other aspects are provided.

摘要： Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may estimate one or more channel availability parameter values. The UE may then select, based on a co-channel configuration indicating a relationship between channel availability parameter values and patterns of sidelink resources, a pattern of sidelink resources (e.g., LTE resources) on which to transmit NR packets. In some examples, a special UE may receive individual or aggregated reports of channel availability parameter values. The special UE may select a pattern of sidelink resources (e.g., LTE resources) on which one of the reporting UEs is permitted to transmit NR packets, and may transmit a message activating the pattern of sidelink resources to the reporting UE. The reporting UE may then use the activated sidelink LTE resources for transmitting NR packets according to the indicated pattern.

摘要： Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may reserve a set of sidelink resources for a first sidelink transmission. A detecting UE may identify a sidelink feedback channel collision arising from a first sidelink feedback transmission to a first UE and a second sidelink feedback transmission to a second UE sharing same feedback channel resources. The detecting UE may determine one or more UEs to transmit a sidelink feedback channel collision indication to, and transmit, the collision indication to the one or more UEs. The first UE may identify a collision involving the first sidelink feedback transmission associated with the first sidelink transmission and the second sidelink feedback transmission associated with a second sidelink transmission by the second UE. The first UE may determine to transmit or retransmit the first sidelink transmission based on the sidelink feedback channel collision being identified.

摘要： A first wireless device may encode a plurality of first blocks into a plurality of second blocks based on a coding scheme. The plurality of second blocks may include redundancy information such that the plurality of first blocks is recoverable based on less than all of the plurality of second blocks if more than a threshold number of second blocks in the plurality of second blocks are decodable. The first wireless device may transmit the plurality of second blocks to a second wireless device. The second wireless device may recover the plurality of first blocks based on less than all of the plurality of second blocks.

摘要： Apparatus, methods, and computer-readable media for sidelink control information forwarding for sensing procedure are disclosed herein. An example method of wireless communication at a forwarding user equipment (UE) includes receiving, from a forwarded UE, control information, and transmitting, to a sensing UE, a forward message including the control information and information associated with the forwarded UE. An example method of wireless communication at the sensing UE includes receiving, from the forwarding UE, a forward message including the control information containing a first measurement of the control information. The example method also includes obtaining a second measurement of the forward message and determining a ratio of the second measurement to the first measurement. The example method also includes selecting a specific resource based on the ratio and whether the forwarding UE is an intended receiver for the sensing UE or the forwarding UE intends to receive from the forwarded UE.
