Abstract: A method of wireless communication by a base station includes configuring a tracking reference signal (TRS) with respect to a physical downlink shared channel (PDSCH) for an idle/inactive mode user equipment (UE). The method also transmits the tracking reference signal and the PDSCH during a paging cycle, in accordance with the configuration. A method of wireless communication by a UE includes expecting a TRS to be received when a PDSCH is received.

Abstract: Methods, systems, and devices for wireless communications are described. Aspects of the present disclosure provide techniques for restricting beams that may lead to inter-base station interference. For example, an implicit restriction of beams may be used by a first and second base station (e.g., a victim and aggressor base station, respectively). In such cases, the first base station may indicate a period, a subband, or both, associated with one or more scheduled uplink beams that the first base station may use for receiving uplink transmissions. The second base station may select beams that avoid interference with the uplink beam(s) of the first base station. Additionally or alternatively, an explicit restriction of beams may be signaled, where the first base station may explicitly indicate a set of downlink beams associated with the second base station that are allowed (e.g., beams that avoid interference with uplink transmissions at the first base station).

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling from a base station that indicates a multicast or broadcast wake up signal (WUS) format. The UE may receive a multicast or broadcast WUS from the base station during a WUS monitoring occasion of a connected mode discontinuous reception (C-DRX) cycle in accordance with the control signaling. The multicast or broadcast WUS may indicate upcoming transmissions for a set of multicast or broadcast services (MBSs). If, for example, the UE is subscribed to a first MBS from the set of MBSs and the multicast or broadcast WUS indicates an upcoming transmission for the first MBS, the UE may monitor for the upcoming transmission during an active duration of the C-DRX cycle. Otherwise, the UE may enter a sleep mode to conserve power.

Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for wireless communication. In one aspect of the disclosure, a UE may transmit a sidelink resource reservation to one or more other UEs for reserving one or more frequency resources of each of a plurality of slots. The sidelink resource reservation may include an indication of a non-integer periodicity of the plurality of slots. The UE may then transmit information in one or more of the plurality of slots. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. For example, a method for wireless communications at a wireless device may include determining a rate matching configuration for a first channel (e.g., an uplink channel) associated with a second channel (e.g., a downlink channel). A wireless device may determine rate matching resources of an uplink channel based on the rate matching configuration. The wireless device may determine rate matching resources of a downlink channel based on the rate matching configuration. The wireless device may transmit a first message on the uplink channel or the downlink channel, respectively, where the transmitted channel includes the rate matching resources. The wireless device may receive a reference signal on one or more resources of the downlink channel or the uplink channel, respectively, where the one or more resources of the respective channel correspond to the rate matching resources on the transmitted channel.

Abstract: Methods, systems, and devices for wireless communications are described. The techniques described herein relate to enhancements to physical downlink control channel (PDCCH) monitoring and skipping. A user equipment (UE) receives, from a network entity, a control message including a control channel skipping indication or a switching indication. The control channel skipping indication or the switching indication is associated with an application delay time duration that indicates a beginning of a control channel skipping or search space set group (SSSG) switching time duration. The UE adjusts an ending time of the application delay time duration based on feedback of whether a message was successfully received via a data channel. The UE skips monitoring of control channel occasions or transitioning from a first SSSG, beginning at the adjusted ending time of the application delay time duration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a control message scheduling a burst of downlink messages. The control message may indicate first and second pluralities of transmission configuration indicators associated with first and second downlink shared channels, respectively. The UE may monitor for a first and second downlink messages in the first downlink shared channel and the second downlink shared channel, using first and second transmission configuration indicators, respectively. Additionally, or alternatively, the UE may receive a control message scheduling a burst of uplink messages. The single control message may indicate to apply a first precoding matrix for transmission of the uplink messages. The UE may precode, using a second precoding matrix, an uplink message to generate a precoded first uplink message. The UE may transmit the precoded uplink message in a first uplink shared channel.

Abstract: Methods, systems, and devices for wireless communication are described. The method may include an energy harvesting (EH) device receiving a first control signal that includes scheduling information for the EH device. The scheduling information may indicate a first set of resources for communicating a first signal and a first offset between receiving the first control signal and communicating the first signal. Further, the method may include transmitting, via a second set of resources, a second signal indicating a second offset between receiving the first control signal and communicating the first signal and communicating the first signal via the first set of resources based on the second offset.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a network entity to indicate one or more wake-up radio (WUR) configurations to a user equipment (UE), which may communicate a desired WUR configuration with the network entity. The UE may indicate a request for the desired WUR configuration, may multiplex the request with another signal associated with the UE, or both. Additionally, or alternatively, the network entity may indicate a single WUR configuration to the UE, which may be determined according to desired configurations, a class of WUR, or both associated with a group of UEs including the UE. Such techniques may support a reduced overall power expenditure of the UE by improving WUR operation.

Abstract: Aspects relate to cross-carrier scheduling in wireless communication. A scheduling entity generates scheduling information that schedules a plurality of data transmissions to or from a user equipment (UE) on a first carrier having a first numerology. The scheduling entity then transmits the scheduling information to the UE on a second carrier having a second numerology different than (e.g., less than) the first numerology. The scheduling information is transmitted using control resources allocated based on slot indexes of a plurality of slots configured for communicating the data transmissions on the first carrier.
