Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) or a base station may select a sequence from a set of sequences for conveying a payload including a set of bits. A length of the selected sequence may be based on a number of time periods for conveying the payload and a number of frequency tones for conveying the payload. The communication device may apply an interleaving function to the selected sequence to generate an interleaved sequence, and transmit the payload including the set of bits using the interleaved sequence. Likewise, the communication device may receive the payload including the set of bits using an interleaved sequence, and apply an interleaving function to de-interleave the interleaved sequence to generate a selected sequence. The communication device may thereby decode the payload based on the selected sequence.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a physical uplink shared channel communication using a resource associated with a configured grant. The UE may transmit, in connection with transmitting the physical uplink shared channel communication, a scheduling request. A base station (BS) may monitor for the physical uplink shared channel communication and the scheduling request. The BS may selectively communicate with the UE to schedule a retransmission of the physical uplink shared channel communication based at least in part on a result of the monitoring. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a resource for a joint uplink transmission comprising a sounding reference signal and a scheduling request. The UE may receive a grant of a set of resources for an uplink data transmission to a base station. The UE may perform the joint uplink transmission comprising the sounding reference signal and the scheduling request using the resource for the joint uplink transmission in connection with performing the uplink data transmission using the set of resources for the uplink data transmission.

Abstract: A second base station may allocate a set of downlink resources for a downlink transmission. The set of downlink resources may include a subset of null resources, which may serve as a signature for the second base station. The second base station may transmit downlink data or reference signals on the set of downlink resources including the subset of null resources. A first UE may experience the downlink transmission from the second base station as interference. The first UE may identify the set of downlink resources. The first UE may identify the subset of null resources. The first UE may transmit, to a first base station, an indication of the subset of null resources. The first base station may identify the second base station based on the indication of the subset of null resources. The first base station may transmit, to the second base station, an interference coordination message.

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: A user equipment (UE) determines an occurrence of a triggering event for providing negative acknowledgment (NACK) based feedback for a semi-persistent scheduling (SPS) transmission. The apparatus monitors for the SPS transmission. The apparatus transmits a NACK if the SPS transmission is not successfully received and refrains from sending an ACK if the SPS transmission is successfully received based on the occurrence of the triggering event for providing NACK based feedback. The base station determines an occurrence of a triggering event for a UE to provide NACK based feedback for an SPS transmission. The apparatus transmits the SPS transmission and determines that the UE successfully received the SPS transmission based on an absence of a NACK from the UE for the SPS transmission.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may receive a downlink control information (DCI) message including an indication to enable discontinuous monitoring of a physical downlink control channel (PDCCH). The UE may enable the discontinuous monitoring of the PDCCH based on the received DCI message, and disable monitoring of the PDCCH during a temporal period in which at least one of physical downlink shared channel (PDSCH) reception, downlink reference signal monitoring, uplink reference signal transmissions, and channel reporting is enabled. The UE may thereby experience power saving by disabling monitoring of the PDCCH while still performing other wireless operations during the temporal period. The UE may, as a result, also include features for improvements to wireless communications and, in some examples, may promote high reliability and low latency wireless communications, among other benefits.

Abstract: An apparatus for wireless communications includes a processor and a memory that includes instructions. The one or more processors are configured to execute the instructions to control reception, from a base station, of a first downlink signal using a first bandwidth amount that is based on a first frequency range associated with a particular signal transmitted by the base station. The one or more processors are further configured to execute the instructions to initiate transmission, to the base station, of a first uplink signal using a second bandwidth amount. The second bandwidth amount is less than the first bandwidth amount, and the second bandwidth amount is based on a second frequency range associated with an uplink channel.
