Abstract: Methods, systems, and devices for wireless communications are described. A scheduled entity transmits an indication of frequency resources that have different transmission requirements from those of other frequency resources in a smallest frequency domain scheduling unit that comprises the frequency resources for the scheduled entity. The scheduled entity receives, from a scheduling entity, signaling indicating at least one characteristic of how a channel is to be scheduled on the frequency resources from a scheduling entity. The scheduled entity communicates with the scheduling entity in accordance with the at least one characteristic.

Abstract: Wireless communications systems and methods related to hybrid repeat request (HARQ) with rate splitting are provided. A first wireless communication device communicates, with a second wireless communication device, a first communication signal including a plurality of information bits. The first wireless communication device determines a number of bits in the plurality of information bits to be repeated in a second communication signal based on channel capacity information. The first wireless communication device communicates, with the second wireless communication device, the second communication signal including the plurality of information bits and a repetition of a subset of the plurality of information bits, where the subset of the plurality of information bits includes the determined number of bits.

Abstract: Systems and techniques are disclosed to reduce pilot overhead by providing common reference signals coded with cover codes that are orthogonal in time and frequency domains. Common reference signals that are coded by cover codes orthogonal in both domains can be de-spread in both the time and frequency domains for improved resolution and larger pull-in windows for both. Also disclosed is semi-uniform pilot spacing in both the frequency and time domains. In a time domain, a first pilot symbol pair is spaced by a first time interval from each other and a second pilot symbol pair is spaced by a second time interval from the first pair, the second interval being greater than the first. In a frequency domain, a first set of pilot symbols is densely placed in a selected frequency band and a second set of pilot symbols is sparsely placed surrounding and including the selected frequency band.

Abstract: Techniques and devices for wireless communications are described. A user equipment (UE) may receive a configuration from a network entity for multiplexing a reference signal with a data signal in time and in frequency or for multiplexing the reference signal in a Doppler domain. The UE may receive an assignment of multiple time-frequency resources from the network entity for transmission of the reference signal. The UE may multiplex the reference signal across the assigned time-frequency resources in accordance with the received configuration. The UE may transmit the multiplexed reference signal to the network entity.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of at least one of: one or more anchor cells associated with a target cell, or one or more target cells, including the target cell, associated with an anchor cell included in the one or more anchor cells. The UE may transmit, to the anchor cell, an indication of the target cell and an indication of a target beam index associated with the target cell as part of an initial access procedure with the anchor cell.

Abstract: Methods, systems, and devices for wireless communications are described. A base station and a user equipment (UE) may communicate in a high reliability and low latency communications system (e.g., ultra-reliable low latency communications (URLLC)). The base station may signal a UE-specific scheduling request (SR) repetition configuration that the UE may utilize to transmit an instantaneous SR when a buffer status report (BSR) is triggered by a new data packet. The UE may repeatedly transmit the SR until a number of repetitions or a time period of repetitions is met or an uplink grant is received from the base station. The SR repetition configuration may include a number of parameters including a repetition setting, power settings, a resource allocation, and an acknowledgement/negative acknowledgment (ACK/NACK) procedure.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may identify a first set of bits associated with a first set of modulation layers. The wireless communication device may interleave a second set of bits associated with a second set of modulation layers to obtain an interleaved second set of bits. The wireless communication device may generate a combined set of bits based at least in part on combining the second set of bits and at least a portion of the first set of bits. The wireless communication device may perform a transmission based at least in part on the combined set of bits and the second set of bits. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may transmit an expiration indication to a receiving device as part of a scheduling message for a transport block. The expiration indication may provide information related to an expiration time for the transport block. If the expiration time is reached prior to successful reception by a receiving device, the receiving device may assume that the transport block has expired and may refrain from transmitting a retransmission grant, or may empty a hybrid automatic repeat request (HARM) buffer associated with the transport block. If the transmitting device fails to successfully receive an indication from the receiving device of a successful reception of the transport block prior to the expiration period, the transmitting device may also assume that the transport block has expired.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of an antenna port mapping from a network entity. The antenna port mapping may be between a tracking reference signal and a corresponding reference signal, the antenna port mapping indicating a mapping of a tracking reference signal port to a plurality of reference signal antenna ports associated with the corresponding reference signal. The UE may receive a tracking reference signal via the tracking reference signal port based on the antenna port mapping. The UE may perform a channel measurement procedure using the tracking reference signal based on the mapping.

Abstract: The disclosure relates in some aspects to an energy-aware architecture that supports a low power scheduling mode. For example, a media access control (MAC) architecture for a base station (e.g., an enhanced Node B) and associated access terminals (e.g., UEs) can take the power needs of the access terminals into account when scheduling the access terminals. In some aspects, an access terminal may support a particular frame structure for a low power mode. Accordingly, scheduling of the access terminal may include use of the particular frame structure during low power mode.
