Abstract: Techniques are described for wireless communication. One method includes identifying a traffic condition associated with data to be transmitted between a network access device and at least one user equipment (UE); selecting, based at least in part on the traffic condition, a dynamic subframe type of a time-division duplex (TDD) subframe; and indicating the dynamic subframe type in a TDD header of the TDD subframe. Another method includes identifying, in a TDD header of a subframe, an indication of a dynamic subframe type of the TDD subframe; and transmitting data or receiving data in a data region of the TDD subframe based at least in part on the dynamic subframe type.

Abstract: Methods, systems, and devices for wireless communication are described. A method may include receiving a control transmission from a base station, identifying a control channel search space organized according to a nested structure, the control channel search space including a plurality of control channel candidates associated with one or more control channel elements (CCEs) and an aggregation level, and searching the received control transmission to identify a control channel for the UE using the plurality of control channel candidates. Another method may include determining whether to reorder resource element group (REG) indices for a received control channel transmission based, at least in part, on a transmission mode associated with the control channel transmission. Another method may include decoding a received control channel transmission, where the downlink control information (DCI) formats may be constrained to an integer multiple of a predetermined base number of bits N.

Abstract: Certain aspects of the present disclosure provide techniques for coordinated power savings configurations for access link and sidelink(s). A wireless node may receive information from a user equipment (UE) over a sidelink. In some aspects, the wireless node forwards the information to a base station (BS) over an access link and receives, from the BS, a first power savings configuration for the access link and a second power savings configuration for the sidelink. In some aspects, the wireless node receives, from a BS, a first power savings configuration for an access link and determines a second power savings configuration for the sidelink based on the information and the first power savings configuration.

Abstract: Aspects described herein relate to physical downlink control channel (PDCCH) limits for multiple cells scheduling one cell in fifth generation new radio (5G NR). In an example, the aspects may include determining a PDCCH limit corresponding to at least one of a number of blind detections (BDs) and a number of control channel elements (CCEs) used for decoding PDCCH candidates for a first cell that schedules a second cell, and at least a third cell that schedules the second cell, wherein the third cell is the same cell as the second cell or the third cell is different from the second cell; and receiving one or more PDCCH transmissions from the first cell and the third cell based on the PDCCH limit.

Abstract: A method of wireless communications by a user equipment (UE) includes transmitting a request for action for at least one control resource set (CORESET) and associated search space. The action may include configuring, activating, and/or deactivating the at least one CORESET and associated search space. The CORESET may be a dynamic CORESET with a predefined number of search space occasions or a semi-static CORESET. The method also includes communicating in accordance with the request. The request is transmitted using at least one of an uplink radio resource control (RRC) message, a physical uplink control channel (PUCCH), a sounding reference signal (SRS), a random access channel (RACH), or a physical uplink shared channel (PUSCH). The UE may switch, in connection with the request, to a bandwidth part (BWP) configured for the UE.

Abstract: In the examples described herein, a user equipment (UE) may identify multiple carriers configured for communications with a base station, and the UE may group the carriers into one or more preferred groups for synchronized scheduling at the base station. The preferred groups of carriers for synchronized scheduling may represent a recommendation that carriers within a preferred group are to be scheduled for communications with the base station on at least partially overlapping resources to maximize power savings at the UE. The UE may transmit an indication of the preferred groups of carriers to the base station, and the base station may identify an actual group of carriers for synchronized scheduling based on the indication received from the UE. The base station may then schedule communications with the UE based on the actual group of carriers.

Abstract: Aspects relate to the extension of cross-slot scheduling for power efficient paging between different New Radio (NR) operating platforms or environments. In some examples, the same paging downlink control information (DCI) may be shared between existing NR user equipment (UE) and new NR UE in different time slots, where a single paging DCI schedules multiple paging messages for each operating environment. In some examples, the same paging physical downlink control channel (PDCCH) occasion may be shared in existing NR and new NR operating environments for scheduling paging messages in different time slots, but different DCIs are used for scheduling the paging messages. In some examples, the same physical downlink shared channel (PDSCH) paging message may be shared in different slots between existing NR and new NR operating environments.

Abstract: Methods, systems, and devices for wireless communications are described that provide for allocation of control channel candidates for multiple component carriers (CCs) in carrier aggregation (CA) communications. A CA limit may correspond to a total number of configurable control channel candidates across multiple CCs. The control channel candidates may include blind decoding (BD) candidates or control channel element (CCE) candidates for channel estimation. A per-CC limit of control channel candidates may correspond to a number of configurable control channel candidates for each CC. An applied set of control channel candidates may be determined by allocating control channel candidates across the multiple CCs based on the CA limit and the per-CC limit. Such techniques may be used in cases where the CCs have a same numerology or mixed numerology, and may also be used for cross-carrier scheduling.

Abstract: Certain aspects of the present disclosure provide techniques for coordinated sidelink power savings configurations. A wireless node may select a sidelink power savings configuration to use for a sidelink between the wireless node and a user equipment (UE), provide the selected configuration to the UE, and follow the configuration for the sidelink. The selection may be based on input from the UE or without input from the UE. The selection may be a current power savings configuration at the wireless node, a power savings configuration suggest by the UE, or a different power savings configuration determined by the wireless node based on the current and suggested power savings configuration. When a new UE connects to the wireless node, the wireless node may reselect a power savings configuration to use for the sidelinks and provide the reselected power savings configuration to the UEs having a sidelink with the wireless node.
