Abstract: Apparatus, methods, and computer-readable media for facilitating sidelink resource pool activation and deactivation for sidelink communication are disclosed herein. An example method for wireless communication at a first sidelink device includes identifying a configuration of a bandwidth part (BWP) for sidelink communication. In some examples, the BWP may comprise at least a first resource pool including a first subset of frequency resources and a second resource pool including a second subset of frequency resources. The example method also includes receiving an activation indication activating the second subset of frequency resources of the second resource pool. Additionally, the example method includes activating the second subset of frequency resources of the second resource pool based on the activation indication.

Abstract: Aspects of the disclosure relate to downlink (DL) transmissions using various powers and assigning frequency resources based on the powers. An example base station may transmit, to a first user equipment (UE), an indication of a first transmit (Tx) power for one or more first DL transmissions to a first group of a plurality of groups. The first group may include the first UE. The first Tx power may have a first power level different from a second power level of a second Tx power for one or more second DL transmissions to a second group of the plurality of groups. Then, the base station may transmit, to the first UE, a first DL transmission of the one or more first DL transmissions using the first Tx power. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described According to one or more aspects of the present disclosure, a user equipment (UE) may receive an uplink grant of an uplink transmission from the UE to the base station. The UE may identify a packet transmission mode indicated in the uplink grant. The indication may specify whether the UE is to transmit the uplink transmission using a default mode, such as a first-in first-out mode, or a packet-group transmission mode. The UE may determine packets for inclusion in a transmission payload for the uplink transmission based on the identified transmission mode and transmit the uplink transmission in accordance with the packet transmission mode and the uplink grant.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may associate a first and second port with a set of antenna elements based on a first and second linear precoding vector. The base station may generate coefficients indicating a first combination and a second combination of a first data set for a first user equipment (UE) and a second data set for a second UE. The base station may apply the first and second linear precoding vectors to the first and second combinations, respectively, transmit a first demodulation reference signal (DMRS) and a second DMRS using a first comb corresponding to the first and second ports, and transmit at least a third DMRS indicating the coefficients using a second comb. The UEs may extract data from the precoded combinations by applying the coefficients and estimating channels associated with the first and second DMRS.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) that is configured with two sets of power control parameters may be signaled (e.g., via downlink control information (DCI)) as to which set of parameters to use for determining the transmission power on a sidelink channel. The UE may determine a transmit power for a sidelink message based on the indication included in the DCI. The base station may transmit the indication based on whether uplink or downlink communications are scheduled on resources that may overlap with resources used for transmission of the sidelink message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a number of repetitions of a message 3 (msg3) communication of a four-step random access channel (RACH) procedure that are to be transmitted to a base station. The UE may transmit, to the base station, the repetitions of the msg3 communication based at least in part on determining the number of the repetitions of the msg3 communication. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, control information that indicates at least two transmission configuration indicator (TCI) states. A first TCI state of the at least two TCI states is associated with a half duplex mode of the UE, and a second TCI state of the at least two TCI states is associated with a full duplex mode of the UE. The UE may further receive, from the base station, a downlink transmission according to at least one of the first TCI state or the second TCI state. Numerous other aspects are provided.

A method for wireless communications by wireless node is provided. The method generally includes encoding a set of information bits based on a LDPC code to produce a code word, the LDPC code defined by a matrix having a first number of variable nodes and a second number of check nodes, puncturing the code word to produce a punctured code word, wherein the puncturing is performed according to a first puncturing pattern designed to puncture bits corresponding to one or more of the variable nodes having a certain degree of connectivity to the check nodes, and transmitting the punctured code word.

Abstract: Methods, systems, and devices for wireless communication are described to estimate interference for concurrent uplink and downlink communications based on an indication of one or more one or more characteristics of an interfering uplink signal communicated between a base station and a second user equipment (UE). The base station or the second UE may transmit, to a first UE, an indication of one or more characteristics of an uplink signal, such as a baseband of the uplink signal or one or more parameters of the uplink signal. The first UE may use the characteristic(s) of the uplink signal to estimate the baseband of the uplink signal and cancel interference associated with the uplink signal. For example, the first UE may use the baseband signal to estimate the interference and may subtract the estimated interference from a downlink signal received at the first UE.

Abstract: Systems, methods, and devices for wireless communication that support mechanisms signaling non-linearities to a victim user equipment (UE) for interference cancellation in a wireless communication system. A victim UE may experience interference from an uplink transmission by an aggressor UE to a base station. The victim UE may obtain a power amplifier model associated with the aggressor UE. The power amplifier may include a non-linearity model of a power amplifier of the aggressor UE causing the interference on the victim UE. The power amplifier model obtained by the victim UE may be dependent on various parameters, such as a transmit power used by the aggressor UE to transmit the uplink transmission causing the interference. Based on the aggressor UE transmit power, the victim UE may select parameters for power amplifier model and may estimate the interference caused by the uplink transmission for interference cancellation.
