Abstract: Aspects relate to a control message that includes at least one symbol mask to be applied to a set of symbols of a time slot. In some examples, the control message may also include at least one resource element mask to be applied to at least one resource element of the time slot. In some aspects, information may be communicated during the time slot according to the at least one symbol mask.

Abstract: Certain aspects of the present disclosure provide techniques for power saving through discontinuous reception (DRX) in multiple subscriber identity module (multi-SIM) user equipment (UE). A method that may be performed by a UE includes determining a first DRX configuration associated with a first SIM and a second DRX configuration associated with a second SIM are asynchronous, generating, based on the first DRX configuration and the second DRX configuration, a synchronous DRX configuration for communicating with the first SIM and the second SIM, transmitting, to a first base station (BS) associated with the first SIM and to a second BS associated with the second SIM, an indication of the synchronous DRX configuration, and communicating with the first BS using the first SIM and the second BS using the second SIM in accordance with the synchronous DRX configuration.

Abstract: A method of wireless communication by an open radio access network-radio unit (O-RU) includes transmitting to an open radio access network-distribution unit (O-DU), a first message including antenna calibration capabilities. The O-RU receives, responsive to the first message, a second message from the O-DU. The second message includes a subscription to calibration mode switching. The O-RU dynamically adapts an antenna calibration mode to a self-calibration mode in response to a radio frequency performance metric being less than a predefined threshold value prior to expiration of a calibration timer.

Abstract: Aspects of the present disclosure relate to techniques for signal compression. Certain aspects described in this disclosure can be implemented in a method for wireless communication by a distributed unit (DU). The method generally includes compressing at least one reference signal (RS) in one or more first set of resource elements (REs) of a symbol and data in one or more second set of REs of the symbol, wherein the at least one RS is compressed using a first compression type and the data is compressed using a second compression type, and wherein the first compression type is different than the second compression type; and sending, to a radio unit (RU), the symbol having the at least one RS in the one or more first set of REs and the data in the one or more second set of REs compressed using the first and second compression types, respectively.

Abstract: An open radio access network (O-RAN) may include a control unit that communicates with a core network, a distributed unit that communicates with the control unit, a radio unit that communicates with the distributed unit and a user equipment (UE). Currently, the O-RAN may lack support for static configuration for a physical uplink shared channel (PUSCH) communication of message-A in a third generation partnership project (3GPP) two-step random access procedure. Hence, according to some aspects of the disclosure, the distributed unit may receive, from a radio unit, a static configuration support indication for receiving payload data via a message in a two-step random access procedure, the message including a preamble and the payload data. The distributed unit may further transmit, in response to receiving the static configuration support indication, static configuration information to the radio unit, the static configuration information for receiving the payload data communicated via the message.
