Abstract: Methods, systems, and devices for wireless communication are described. Wireless communications systems as described herein may be configured to support several service types with different latency, reliability, or throughput rates or standards. One such service type may be referred to as ultra-reliable, low-latency communications (URLLC). Enhancements to improve URLLC performance in coexistence with and as a complement to legacy service types, such as LTE are described. These include, for example, enhanced timing resource allocations, enhanced transmission repetition schemes, enhanced feedback mechanisms, or a combination of these features to achieve certain reliability and latency targets.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter device may determine that a communication is to be transmitted on a shared spectrum during a channel access interval not reserved for the communication. The transmitter device may determine, based at least in part on determining that the communication is to be transmitted, that a detection power of a listen-before-talk (LBT) operation satisfies a threshold. The transmitter device may transmit, after a coordinated rate control region and based at least in part on the detection power of the LBT operation satisfying the threshold, a reservation request signal associated with the communication. The transmitter device may transmit the communication before an end of the channel access interval based at least in part on a response to the reservation request signal. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may obtain access to a shared radio frequency spectrum band for a transmission opportunity. The UE may perform an autonomous uplink transmission over the shared radio frequency spectrum band during a first portion of the transmission opportunity. The UE may transmit a physical layer scheduling request comprising a transmission size parameter for a second portion of the transmission opportunity. The UE may receive an uplink grant for the second portion of the transmission opportunity based at least in part on the scheduling request. The UE may perform a scheduled uplink transmission over the shared radio frequency spectrum band during the second portion of the transmission opportunity according to the uplink grant.

Abstract: Wireless communications systems and methods related to constraining no-listen-before-talk (LBT)-based transmissions during link direction switches in a frequency spectrum shared by multiple network operating entities are provided. A first wireless communication device, communicates, with a second wireless communication device, a configuration for determining whether to perform an LBT after a link direction switch. The first wireless communication device communicates, with the second wireless communication device, a first communication signal in a first link direction during a channel occupancy time (COT) period of the first wireless communication device or the second wireless communication device. The first wireless communication device communicates, with the second wireless communication device, a second communication signal in a second link direction different from the first link direction during the COT period based on the configuration.

Abstract: Apparatuses and methods are disclosed for determining a transport block size (TBS) as a function of various parameters without cyclic dependencies between the parameters and TBS. The disclosed function can determine a TBS in a single pass, and the determined TBS allows the use of code blocks with equal code block size (CBS) in a transport block segmentation process. The determined TBS can provide byte-aligned code block lengths and require no padding bits in a transport block.

Abstract: Methods, systems, and devices for wireless communication are described for a channel reservation signal that may be transmitted upon gaining contention-based access to a channel in a shared radio frequency spectrum. The channel reservation signal may include a channel reservation preamble and a channel reservation payload. The channel reservation payload may be formatted with other control channel information transmitted by the transmitter, such as downlink control information (DCI), and aligned with a transmission boundary of the other control channel information. When deployed on a shared medium, a downlink control channel may carry an extra trigger field that may schedule a receiving UE to transmit its own channel reservation signal within an uplink transmission burst.

Abstract: A control channel transmission may include information for downlink transmissions, and another control channel, such as a physical micro sleep indicator channel (PMSICH), may include information for uplink transmissions that a user equipment (UE) may use to enter a power-saving micro sleep state. A base station may drop PMSICH transmissions in the event that downlink resources are constrained. A UE that receives a PMSICH transmission may determine an uplink transmission duration, and enter a micro sleep state for all or a portion of the uplink transmission duration.

Abstract: Methods, systems, and devices for wireless communications are described. A number of blind decodings of a search space set for control information are defined. A search space of the search space set includes a subset of blind decodings. A reduction factor is determined. The reduction factor is applied to the subset of blind decodings to obtain a reduced subset of blind decodings for the search space. A reduced number of blind decodings of the search space set is identified based at least in part on the reduced subset of blind decodings for the search space. The control information is transmitted in a decoding candidate of the reduced number of blind decodings of the search space.

Abstract: Techniques are described for wireless communication. A first method includes receiving downlink control information for a first UE based at least in part on a group identifier associated with a NOMA group including the first UE and at least a second UE; and receiving a set of NOMA downlink transmissions at the first UE based at least in part on the downlink control information for the first UE. A second method includes receiving downlink control information for a first UE, the downlink control information for the first UE including an indication of at least a second UE; receiving downlink control information for the second UE based at least in part on the indication of at least the second UE; and receiving a set of NOMA downlink transmissions at the first UE based at least in part on the downlink control information for the first UE and the downlink control information for the second UE.
