Abstract: Methods, systems, and devices for wireless communications that support physical uplink control channel (PUCCH) carrying hybrid automatic repeat request (HARQ-A) for multiple transmission reception point (multi-TRP) environments with non-ideal backhaul links are described. A user equipment (UE) may support multiple communication links with TRPs and receive distinct physical downlink control channel (PDCCH) messages that include downlink control information (DCI). The DCI may include a timing or resource indication index values for physical uplink control channel (PUCCH) transmission. Based on the index values, the UE may differentiate the received DCI indications. The UE may then schedule PUCCH transmissions, including hybrid automatic repeat request (HARQ) payloads, directed to the TRPs. In some examples, the scheduling may include mapping the PUCCH transmissions to resources or resource groups in configured PUCCH resource set. The UE may then transmit the PUCCH messages via one or more determined beams based on the indication index values.

Abstract: In one aspect, an apparatus of wireless communication at a user equipment includes receiving, during a radio resource control (RRC) setup, a sounding reference signal (SRS) resource set configuration including a specified time offset x. The UE may receive downlink control information (DCI) in a later time slot and an instruction to trigger the SRS resource set. The UE determines, based on information from the SRS configuration or the DCI, a starting position within a time slot for transmitting an SRS resource. The UE transmits, at the starting position x slots after the later time slot, a reference SRS resource selected from the SRS resource set, followed sequentially by the remaining resources. In another aspect a UE that receives a t value of multiple t values may transmit the reference resource in a (t+1)th time slot from a reference slot.

Abstract: An apparatus for wireless communication includes a memory and one or more processors coupled to the memory. The one or more processors are configured to determine a plurality of pre-coders available for uplink transmissions and to select a particular pre-coder from among the plurality of pre-coders. The one or more processors are further configured to initiate encoding of an uplink signal based on the particular pre-coder to generate a pre-coded uplink signal. The pre-coded uplink signal has one or more characteristics that enable a base station to identify the particular pre-coder. The one or more processors are further configured to initiate transmission of the pre-coded uplink signal.

Abstract: Aspects described herein relate to determining multiple beams to use in transmitting messages in a random access procedure with one or more transmission/reception points (TRPs) of a cell, and transmitting, to the one or more TRPs of the cell, multiple instances of a first random access message based on the multiple beams, where each of the multiple instances of the first random access message include a preamble portion and a payload portion. In another aspect, a node receiving the multiple instances of the first random access message can determine multiple beams to use in transmitting messages in the random access procedure and can transmit with one or multiple TRPs, to the UE and in response to the first random access message, multiple instances of a second random access message based on the multiple beams.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive single downlink control information (DCI) that indicates resources for a plurality of transmission configuration indicator (TCI) states for transmitting or receiving communications in a plurality of transmission time intervals (TTIs). The UE may transmit or receive the communications in the plurality of TTIs in accordance with the DCI. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A serving cell may configure one or more neighbor cells to perform measurements on sounding reference signals (SRSs) received from a user equipment (UE). The serving cell and a subset of the one or more neighbor cells may then transmit data to the UE in a single frequency network (SFN) transmission based on the SRS measurements. For instance, the serving cell may determine whether to add each of the one or more neighbor cells to an SFN cell group for an SFN transmission to a UE based on measurements performed by each neighbor cell on SRSs received from the UE. A neighbor cell of the one or more neighbor cells may also determine which beam to use for an SFN transmission to a UE based on measurements performed by the neighbor cell on SRSs received from the UE.

Abstract: Example implementations include a method, apparatus and computer-readable medium of wireless communication. A user equipment (UE) may receive a downlink control information (DCI) indicating two or more transmission configuration indication (TCI) states for a physical downlink shared channel (PDSCH). The UE may differentiate that the two or more TCI states apply to all demodulation reference signal (DMRS) ports or all transmission layers across all resource blocks and symbols for the PDSCH from TCI states that apply to different sets of DMRS ports or different sets of resource blocks or symbols. The UE may generate a composite quasi-co-location (QCL) based on the two or more TCI states in response to the differentiating. The UE may receive the PDSCH based on the composite QCL.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may determine a first uplink configured grant configuration corresponding to a first value of a control resource set (CORESET) pool index, and determine a second uplink configured grant configuration corresponding to a second value of the CORESET pool index different from the first value of the control resource set pool index. The UE may transmit a first uplink transmission during a first uplink grant occasion according to the first uplink configured grant configuration and a second uplink transmission during a second uplink grant occasion according to the second uplink configured grant configuration. Both the first uplink transmission and the second uplink transmission may correspond to a same transport block and a hybrid automatic repeat request (HARQ) identifier.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a network device, a downlink control channel order requesting the UE to participate in random access procedure via two or more downlink control channel candidates associated with different transmission configuration indicator (TCI) states that are linked for repetition. In some examples, downlink control information conveying the downlink control channel order may indicate which TCI state to use for the random access procedure. In some examples, the UE may select a TCI state to use for the random access procedure, for example, based on the channel quality of the downlink control channel candidates.
