Abstract: Methods and apparatuses for adaptive subcarrier spacing in wireless communication networks are described. For example, the described aspects include transmitting, from the UE to a network entity, a first PRACH transmission with a first subcarrier spacing; determining, by the UE, that the first PRACH transmission to the network entity is not successful; and transmitting, from the UE, a second PRACH transmission with a second subcarrier spacing in response to determining that the first PRACH transmission is not successful, wherein the first subcarrier spacing is different from the second subcarrier spacing.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit an encoded transmission via a broadcast to multiple user equipment (UE). Subsequently, the multiple UEs may transmit assistance information to the base station based on attempting to decode the broadcasted encoded transmission. If the decoding is unsuccessful for at least one UE, the base station may then transmit an additional encoded transmission via a unicast or multicast message to the UEs that were unsuccessful. Additionally, the base station may transmit configuration information for the multiple UEs to receive the encoded transmissions and to transmit the assistance information. For example, the configuration information may include portion information for how long the encoded transmission is transmitted via the broadcast, via the unicast, when to transmit the assistance information, etc. In some cases, the configuration information may be based on UE metrics of the multiple UEs.

Abstract: Methods, systems, and devices for wireless communications are described to support communication between a base station and a user equipment (UE) via multiple transmission reception points (TRPs). The base station may configure the UE to report a precoding matrix indicator (PMI) for various transmission modes, including one or more transmission modes for multiple TRPs. The UE may determine and report first PMI to the base station for each single TRP transmission mode, and the base station may use the first PMI to determine a precoding matrix for each TRP. The UE may determine and report partial PMI to the base station for the one or more multi-TRP transmission modes. The base station may use respective partial PMI to determine a precoding matrix for each multi-TRP transmission mode and may communicate with the UE using the determined precoding matrix or matrices.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications and more specifically to search space configuration in systems utilizing devices with limited communications resources, such as machine type communication (MTC) devices and enhanced MTC (eMTC) devices. An example method generally includes receiving a physical random access channel (PRACH) signal from a first user equipment (UE) on a first narrowband region within a wider system bandwidth and transmitting, in response to the PRACH signal, a random access response (RAR) signal in a first search space in a second narrowband region in at least a first subframe.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a first transmission from a first device to be received at a second device. The second device may determine one or more interference parameters (e.g., a maximum allowable interference power) for receiving the first transmission from the first device, and the second device may transmit an indication of the one or more interference parameters using a full-duplex operation (e.g., using resources overlapping with resources used to receive the first transmission). The third device may receive the indication of the one or more interference parameters and determine transmission parameters (e.g., a maximum transmit power) for communicating with a fourth device based on the one or more interference parameters. The third device may transmit a second transmission to the fourth device based on the transmission parameters.

Abstract: Certain aspects of the present disclosure provide techniques for using subband precoding for uplink transmissions. In some cases, a UE may receive, from a network entity, at least one of a first downlink control information (DCI) or a second DCI, each DCI indicating at least one of one or more sets of one or more frequency domain (FD) bases and linear combination coefficients and transmit a PUSCH with subband precoding determined based on the first DCI, the second DCI, or a combination of the first and second DCI, depending on whether the first DCI is received, the second DCI is received, or both the first and second DCI are received.

Abstract: Methods, systems, and devices for wireless communications are described. In some cases, a user equipment (UE) may In support multiple component carriers that may be used to transmit uplink transmissions. One carrier may be used at a time such that the may switch between the carriers based on an uplink transmission schedule. In some cases, switching may be limited by a consecutive uplink switching rule or UE capability. In some cases, the gap between two consecutive uplink carrier switching operations may be limited to a resource (e.g., slot, symbol), such that the UE may expect to perform at most one switching operation per resource. In some implementations, the gap between two consecutive uplink carrier switching operations may be limited to a duration (e. g., 14 symbols, 4 symbols), such that the UE may expect to perform at most one switching operation per a duration less than or equal to a threshold.

Abstract: Disclosed are techniques related to wireless communication system to enable full duplex communication. A network node may include a transceiver, a memory, and a processor communicatively coupled to the transceiver and the memory. The transceiver, memory, and processor may be configured to determine downlink (DL) parent and child link priorities for parent and child time-domain resources that overlap in time at least partially. The transceiver, memory, and processor may also be configured to determine DL parent and child beams based on the DL parent and child link priorities. The transceiver, memory, and processor may further be configured to notify the parent node of the DL parent beam for the parent and child time-domain resources. The transceiver, memory, and processor may yet further be configured to concurrently receive parent traffic from the parent node using the DL parent beam and transmit child traffic to the child node using the DL child beam.
