Abstract: Aspects of the present disclosure provide for the pairing of an inter-band carrier with a time division duplex (TDD) carrier. If the paired band is a frequency division duplex (FDD) band, then base stations and mobile devices may transmit and receive additional thin control channels on FDD carriers to enable full duplex operations. If the paired band is a TDD band, then a conjugate or inverse carrier may be used such that full duplex, or a close approximation thereto, is achieved. With the introduction of a paired channel and fast control channels, rapid uplink/downlink switching may be achieved for TDD carriers efficiently and effectively. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be capable of operating according to a first transmission efficiency operating mode and a second transmission efficiency operating mode that is less power efficient than the first transmission efficiency operating mode. The first transmission efficiency operating mode may be associated with a first undesired emission level that is greater than a second undesired emission level associated with the second transmission efficiency operating mode. The UE may select to operate in one of the two transmission efficiency operating modes based on one or more communication parameters (e.g., indicated by control signaling received from a base station). For example, the UE may select to operate in the first transmission efficiency operating mode based on determining that one or more of the communication parameters satisfies at least one parameter criterion for operating in the first transmission efficiency operating mode.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for efficiently transmitting uplink signals to a base station using shared antennas. A first device may be in communications with a base station using local antennas and may identify a second device having auxiliary antennas available for transmitting uplink signals to the base station. Because the local antennas and auxiliary antennas may have different capabilities (e.g., due to different power or other constraints), the first device may generate first uplink signals for transmission using the local antennas differently from second uplink signals for transmission using the auxiliary antennas. The first device may transmit the first uplink signals to the base station using the local antennas and transmit the second uplink signals to the second device for transmission to the base station using the auxiliary antennas based on different configurations.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive signaling that configures a downlink bandwidth for a broadcast channel transmission (e.g., a physical downlink control channel transmission). The UE may determine a bandwidth of the capability is less than the downlink bandwidth, and monitor search space occasions in a period to receive samples of the broadcast channel. The period and the search space occasions may be associated with a control resource set and a search space set. The UE may receive the samples in non-overlapping subbands of the bandwidth according to the bandwidth capability, and detect the broadcast channel based on the samples. The UE may additionally monitor repeated transmission occasions in the period based on detecting the broadcast channel to detect a second broadcast channel (e.g., a physical downlink shared channel).

Abstract: Techniques are described for wireless communication. An exemplary method includes receiving, at a first device, a pre-scheduling message for a downlink transmission from a second device; transmitting a scheduling message to the second device in response to receiving the pre-scheduling message; and receiving the downlink transmission in accordance with the at least one downlink transmission parameter of the scheduling message. The scheduling message may include at least one downlink transmission parameter. Another exemplary method includes transmitting, to a first device, a pre-scheduling message for a downlink transmission; receiving, from the first device, a scheduling message comprising at least one downlink transmission parameter; and transmitting the downlink transmission to the first device in accordance with the at least one downlink transmission parameter of the scheduling message.

Abstract: Methods, systems, and devices are described for wireless communication. In one method, a method of wireless communication at a user equipment (UE) includes receiving a synchronization signal. The synchronization signal may be common to a plurality of cells within a network.

Abstract: Methods, systems, and devices for wireless communication are described. A discontinuous reception (DRX) periodicity may be configured to enable monitoring of a reference signal (RS) for RLM procedures. For example, a transmitting device may configure a DRX periodicity for an RS, where the configured DRX periodicity may include a periodicity of discrete transmissions of the RS or a periodicity of a transmission window in which the RS is located. Accordingly, a receiving device may identify the DRX periodicity and monitor radio link quality using the RS based on the DRX periodicity. In some examples, the RS may be transmitted independent of control channel transmissions, and the transmitting device may configure one or more control resource sets for the RS.

Abstract: Techniques for wireless communications in a system with long term evolution (LTE) integrated with new radio (NR) are provided. A method for wireless communications includes determining a configuration of component carrier(s) (CCs) of a first radio access technology (RAT) and CC(s) of a second RAT. The method also includes identifying one of the CC(s) in the first RAT as an uplink anchor CC based on the configuration. The method further includes identifying a HARQ timing for at least one of the CC(s) of the second RAT based on at least one of a symbol duration, a transmit time interval (TTI) length or a subframe structure of the one of the CC(s) of the first RAT. The method further yet includes sending feedback to a second node in the identified uplink anchor CC for transmissions received in the CC(s) of the second RAT.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for interference management with adaptive resource block (RB) allocation. In an exemplary method, a base station (BS) obtains an indication that downlink transmissions to a first user equipment (UE) potentially interfere with uplink transmissions by a second UE, the BS dynamically allocates, based on the indication, a first set of one or more resource blocks (RBs) for the downlink transmissions to the first UE, and the BS then transmits an indication of the first set of RBs to the first UE. Other aspects, embodiments, and features are also claimed and described.
