Abstract: A method of wireless communication at a transmitting device includes adding parity check bits to a set of information bits. The method also includes generating a non-coherent transmission signal by mapping the parity check bits and the set of information bits into a sequence of complex symbols. Further, the method may include transmitting the non-coherent transmission signal to a receiving device. A method of wireless communication at a receiving device includes receiving, from a transmitting device, a non-coherent signal having at least one segment. Each segment comprises a sequence of complex symbols corresponding to information bits and parity check bits. The method also includes jointly detecting the sequences from each segment of the received non-coherent signal by using the parity check bits.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a first transmit power that is to be used for a first transmission to a source cell and a second transmit power that is to be used for a second transmission to a target cell during a dual-active-protocol stack (DAPS) handover procedure. The UE may transmit, concurrently, the first transmission to the source cell using the first transmit power and the second transmission to the target cell using the second transmit power. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a first message indicating a plurality of measurement configurations, each measurement configuration of the plurality of measurement configurations may include different sets of measurement parameters used for measuring a reference signal (RS) of a cell. The UE may also receive, from the base station, a second message indicating that the UE activate a first measurement configuration, deactivate the first measurement configuration, or switch to the first measurement configuration, where the first measurement configuration is from the plurality of measurement configurations. The UE may determine a measurement reporting scheme based at least in part on the indication to activate, deactivate, or switch to the first measurement configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to monitor, via a receive beam, a first transmission time interval (TTI) of a plurality of different TTIs for a control resource set. The UE may decode the control resource set to obtain a first grant and a second grant. Upon decoding the control resource set, the UE may determine that the first grant and the second grant are associated with different parameters. In some cases, the parameters may be spatial quasi-colocation (QCL) assumptions mapped to the control resource set. The UE may decode, resources of a shared data channel indicated in at least one of the first grant and the second grant. In some cases, the UE may decode the resources during at least one of the first TTI and a second TTI of the plurality different TTIs.

Abstract: In aspects, a base station and a user equipment (UE) exchange synchronization signal blocks (SSBs) carrying a SFN identity, and a waveform of the SSBs has a secondary synchronization signal (SSS) symbol preceding a primary SS symbol. In aspects, a base station transmits a radio access network area code (RAN-AC) SS and RAN-AC page are quasi co-located (QCL). In aspects, a base station transmits a RAN-AC SS over a SFN while avoiding overlap of RAN-AC SS resources with channels employed for initial access of update area cells. In aspects, a base station provides a control resource set (CORESET) to a UE upon release from a connected state, and the UE receives a RAN-AC paging PDCCH based on the CORESET. In aspects, a base station transmits a SFN wake up signal (WUS) when there is a grant for paging, and the UE monitors for the WUS.

Abstract: Methods, systems, and devices for wireless communications are described. A base station determines configuration information for a random access procedure, where the configuration information includes a repetition pattern associated with a first message of the random access procedure. A user equipment (UE) receives, from the base station, a configuration message that indicates the configuration information for the random access procedure. The UE determines a repetition pattern associated with a first message of the random access procedure based on the configuration information. The base station receives, from the UE, multiple instances of the first message based on the repetition pattern.

Abstract: Techniques for implicitly configuring resources for radio link monitoring or beam failure detection. An example method generally includes identifying that RLM resources or BFD resources are configured implicitly by at least in part: obtaining TCI states, for PDDCH CORESETs, obtaining an indication that at least one of the TCI states is activated to become an active TCI state of the PDCCH CORESETs, identifying one or more CSI-RS resources configured in the at least one of active TCI states of the PDCCH CORESETs, and if the UE does not support RLM or BFD based on the CSI-RS or the one or more CSI-RS resources are AP or SP, determining a SS block for RLM or BFD that has a QCL relationship with the one or more CSI-RS resources of the at least one of active TCI states; and performing RLM or BFD based on the SS block.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may attempt to connect to a base station using a random access procedure. During the random access procedure, the base station may transmit control information and data associated with a random access response (RAR) during an RAR window. The UE may identify a channel quality and may transmit a random access request of a first type to the base station. The base station may receive the random access request and transmit repeating instances of the control information or the data, or both, based on identifying that the random access request is of the first type. The UE may use soft-combining to increase the likelihood of successfully decoding the control information and the data associated with the RAR, and likewise may increase the likelihood of successfully receiving the RAR from the base station.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may attempt to connect to a base station using a random access procedure. During the random access procedure, the base station may transmit control information associated with a random access response (RAR) during a RAR window. The UE may attempt to receive a single instance of the control information and, in some cases, may be unable to receive and decode the single instance of the control information. The base station may configure one or more RAR windows (or segment(s) thereof) to support transmitting repeating instances of the control information and/or RAR. The UE may identify a quantity of instances of the repeated control information and combine the instances. The UE may successfully decode the combined instances of control information and identify a location for receiving the RAR.
