Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for DMRS allocation in sub-band FD. For transmission of UL data in a set of symbols having UL DMRS in at least one symbol, a UE may determine which symbol(s) in a subframe will receive DL DMRS so that the UE may align the transmission of the UL DMRS with a reception of the DL DMRS. For transmission of DL data in a set of symbols having a DL DMRS, a BS may determine for a first subset of symbols that a PUSCH will be received from the UE or determine for a second subset of symbols that a PUSCH will not be received from the UE. The BS insert a DL RS within the first subset of symbols or the second subset of symbols based on the determination regarding the PUSCH.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first indication that a network node is in a sleep mode. The UE may receive a second indication of periodic wake-up signal (WUS) occasions associated with the sleep mode. The UE may receive a third indication to defer, for one or more WUS occasions, a transmission of a WUS associated with data, deferral of the transmission being based at least in part on a latency parameter associated with the data. Numerous other aspects are described.

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.

Abstract: Aspects are provided for HARQ feedback and retransmission procedures for cooperative relaying in sidelink networks. A relay attempts to decode sidelink data received from a source for relay to a destination. The relay may combine LLRs for the sidelink data and for a retransmission of the sidelink data. The relay determines a resource of a wireless channel for transmitting feedback to the source in response to the decoding attempt. If decoding is successful, the relay transmits the data to the destination. The destination then attempts to decode the data received from the relay. The destination may combine LLRs for the data and for a retransmission of the data. The destination determines a resource of a wireless channel for transmitting feedback to the relay in response to the decoding attempt. The resources are based on a relay identifier associated with the relay.
