Abstract: Methods, systems, and devices for wireless communications are described. Techniques are described for providing additional feedback about a channel as part of a feedback procedure. Feedback information associated with a feedback procedure may include two stages of feedback information. Each stage of feedback information may include a different type of information. A first stage may include acknowledgements or negative acknowledgements for each feedback process supported. A second stage may include additional feedback information related to any downlink transmission that was not received successfully and thus included a negative acknowledgement in the first stage. Additionally, or alternatively, the second stage may include additional feedback information related to any downlink transmission that was received successfully and thus included an acknowledgement in the first stage. Techniques are also described for handling the variable size of the feedback information included in the two stages.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure resources on a first communication link for scheduling requests and may transmit an indication of the configured resources over a second communication link to a first device. The first device may relay the indication of the configured resources to a second device via the first communication link. The second device may identify that resources on the first communication link are unavailable for a transmission and may transmit a scheduling request. The first device may receive the scheduling request. The first device may transmit, over the first communication link and based on the scheduling request, an indication of one or more shared channel resources configured by the base station for the transmission. The first device may receive, over the first communication link, the transmission over the one or more shared channel resources.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink transmission via at least one of a primary cell, a secondary cell, or a combination thereof. The UE may identify a feedback indication for the downlink transmission. The UE may transmit a first feedback message that includes the feedback indication via the primary cell. The UE may transmit a second feedback message that also includes the feedback indication via the secondary cell.

Abstract: Methods, systems, and devices for wireless communications are described that support joint allocation for both an uplink message and a downlink message. In some cases, joint downlink control information (DCI) may indicate a time domain resource allocation (TDRA) for a downlink data channel and an uplink data channel. For example, bits of the joint DCI may be configured to indicate TDRA parameters of a downlink data channel (e.g., starting symbol, length value, slot offset, mapping type, timing advance, number of repetitions) and based on the TDRA parameters of the downlink data channel, TDRA parameters for an uplink data channel may be determined by a user equipment (UE) using the joint DCI.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may transmit capability information including an indication of a discontinuous monitoring delay period. The UE may receive a message including an indication to adjust monitoring of a physical downlink control channel (PDCCH), and monitor for the PDCCH during the discontinuous monitoring delay period. The UE may adjust monitoring for the PDCCH following the discontinuous monitoring delay period during a temporal period based on the received indication to adjust monitoring of the PDCCH. In some examples, at least one of physical downlink shared channel (PDSCH) reception, downlink reference signal monitoring, uplink reference signal transmissions, and channel reporting is enabled during the temporal period while monitoring of the PDCCH is adjusted.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) determines (e.g., based on an indication from base station) one or more physical random access channel (PRACH) preamble transmission parameters associated with one or more PRACH coverage enhancement (CE) levels of a RACH procedure. The UE and the base station perform a RACH procedure in accordance with the one or more PRACH preamble transmission parameters.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration signal indicating a codebook construction configuration for constructing a codebook of sequences for conveying a first type of uplink payload in a resource block that is orthogonal to a second type of uplink payload transmitted from a second UE in the resource block. The UE may construct the codebook of sequences for the first type of uplink payload according to the codebook construction configuration. The UE may generate the first type of uplink payload for transmission using a first sequence from the codebook of sequences. The UE may transmit the first type of uplink payload in the resource block, wherein the first type of uplink payload is multiplexed in the resource block with the second type of uplink payload from the second UE.

Abstract: Methods, systems, and devices for wireless communications are described to support relayed sidelink communications. A first device and a base station may communicate via a communication link including a sidelink link between the first device and a second device and a relay link between the second device and the base station. The base station may determine restrictions for the communication link and transmit an indication of the restrictions over the relay link. The restrictions may differentiate data originating from the first device and the second device, restrict the first device to one or more resources, or associate logical channels at the first device with one or more transport block sizes and communication links. The second device may relay the indication of the restrictions to the first device. The first device, the second device, and the base station may communicate over the communication link according to the restrictions.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support allocation of resources for a physical broadcast channel (PBCH) for reduced bandwidth devices. In a first aspect, a method includes monitoring, by a user equipment (UE) configured for reduced bandwidth operation, at least a subset of a first set of time and frequency resources allocated to a synchronization signal block (SSB) for UEs configured for non-reduced bandwidth operation. The SSB includes synchronization signals and a PBCH. The method includes monitoring, by the UE, a second set of time and frequency resources allocated to the PBCH for UEs configured for reduced bandwidth operation. The method includes receiving, by the UE, the synchronization signals and the PBCH within at least the subset of the first set of time and frequency resources and the second set of time and frequency resources. Other aspects and features are also claimed and described.
