Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a network entity may determine to transmit first downlink control information (DCI) associated with a demodulation reference signal (DMRS) allocated to multiple resource elements of a control channel. The network entity may select a CDM group used for encoding second (e.g., future) DCI, for example, based on identifying a phase change pattern associated with the CDM group. A user equipment (UE) may monitor for the DMRS during a first time interval, and determine the CDM group for encoding the second DCI, for example using blind decoding. In some cases, the UE may receive the second DCI via the control channel based on the CDM group determined in association with the second DCI.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, a reference signal. The UE may transmit, to the network entity and via a feedback channel, digital pre-distortion (DPD) information that is based at least in part on the reference signal, wherein the DPD information indicates an estimate of non-linearities of a power amplifier at the network entity based at least in part on the reference signal. Numerous other aspects are described.

Abstract: A UE determines an activity status associated with each CC of a set of CCs based on PDCCH decoding of DCI. The set of CCs may be associated with hardware modules at the UE. An inactive set of CCs may be determined to have an inactive activity status. An active set of CCs may be determined to have an active activity status. The inactive set of CCs may be associated with a first set of hardware modules of the hardware modules. The active set of CCs may be associated with a second set of hardware modules of the hardware modules. The UE may activate a partial sleep mode at the first set of hardware modules associated with the inactive set of CCs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a control channel message encoded according to a first format that is associated with a different set of shared data channel parameters than a second format supported by the UE. The second format is a legacy format relative to the first format. The UE may further determine that the control channel message is encoded according to the first format based at least in part on comparing one or more bit values, of the control channel message, in bit positions corresponding to a set of bits defined by the second format, and one or more expected bit values defined by the first format. The UE may select one or more resources for transmission based at least in part on information included in the control channel message. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for sidelink (SL) channel selection coordination. A method that may be performed by a user equipment (UE) includes measuring, during a time period shorter than one slot, a channel condition of at least one first channel in a sidelink (SL) frequency band. The method further includes transmitting a signal on the at least one first channel or a second channel of the SL frequency band, wherein the at least one first channel or the second channel is chosen based on the channel condition.

Abstract: A method of wireless communication at a user equipment (UE) includes receiving a first collision report (s), each first collision report indicating at least one first monitored subset of sidelink resources that were monitored by a remote sidelink UE. The method also includes transmitting a second collision report indicating allocation collisions detected by the UE on a second monitored subset(s) of sidelink resources. Each of the second monitored subset(s) of sidelink resources differing from each of the first monitored subset(s) of sidelink resources indicated in the received first collision report(s). The second collision report further comprising an indication of each of the second monitored subset(s) of sidelink resources.

Abstract: A method of wireless communications by a user equipment (UE) includes transmitting a wakeup message to awaken a base station from a sleep mode. The method also includes communicating with the base station after the base station awakens. A method of wireless communications by a base station includes entering a sleep mode when no user equipments (UEs) are connected to the base station. The method also includes receiving a signal from a UE to awaken from the sleep mode. The method further includes resuming signal transmissions after waking up from the sleep mode

Abstract: A user equipment (UE) transmits a first transmission comprising first sidelink control information (SCI) using a first cyclic shift, where the first SCI includes information about a second cyclic shift of second SCI for a second transmission from the UE. The UE then transmits the second transmission comprising the second SCI using the second cyclic shift. A receiving UE receives, from a second UE, a first transmission comprising first SCI having a first cyclic shift and uses information in the first SCI to determine cyclic shift information about a second cyclic shift of second SCI for a second transmission from the UE. The receiving UE may exclude the second cyclic shift from selection using the information received in the first SCI.

Abstract: The apparatus may be a UE configured to identify at least one performance metric associated with a channel estimation operation at the UE. The apparatus may further be configured to calculate at least one uncertainty value associated with the at least one performance metric. The apparatus may also be configured to transmit, to a network node, a first indication of the at least one uncertainty value associated with the at least one performance metric. The apparatus may be a network node, configured to receive, from a UE, the first indication and a second indication of at least one value for the at least one performance metric associated with the at least one uncertainty value and to select a set of parameters for a subsequent communication based on the at least one value for the at least one performance metric and the at least one uncertainty value.

Abstract: A first wireless device outputs, to a second wireless device, a first indication of a set of TR locations associated with a communication channel, where the set of TR locations are selected based on an estimate of an associated communication channel. The first indication of the set of TR locations includes at least one of a subcarrier bitmap, a granularity for the subcarrier bitmap, a subcarrier RIV, or a CSI-RS for TR. The network entity outputs a communication for the second wireless device, the communication including a first set of data tones and a second set of reserved tones, in a same symbol, based on the first indication of the set of TR locations.
