Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) having partially coherent antennas may be configured for simultaneous transmissions on groups of antennas (e.g., multiple pairs of antennas). To achieve the benefits of simultaneous transmissions using groups of antenna that are partially coherent, without having the transmissions affect each other (e.g., interference), the UE may apply a hybrid closed-loop multiple-input multiple-output (MIMO) scheme among each antenna in the antenna groups where phase coherence can be maintained. Following the hybrid closed-loop MIMO scheme, the UE may apply a transparent diversity scheme across each antenna of the groups. Alternatively, the UE may first apply the transparent diversity scheme and next apply the hybrid closed-loop MIMO scheme. By applying a hybrid closed-loop MIMO scheme, as well as a transparent diversity scheme, the UE may fully realize its resources and contribute to an improved spatial diversity for a MIMO system.

Abstract: Methods, systems, and devices for wireless communications are described. One method may include receiving radio resource control signaling configured with a first set of demodulation reference signal parameters for transmission of an uplink data channel of a type, receiving downlink control information of a format to activate the transmission of the uplink data channel, identifying a second set of demodulation reference signal parameters for transmission of the uplink data channel of the type based on the received downlink control information, and activating the transmission of the uplink data channel using the first and second set of demodulation reference signal parameters.

Abstract: A user equipment (UE) may apply transmit power control (TPC) commands and transmit uplink information based on received downlink control information (DCI). A UE may receive multiple DCI messages including multiple TPC commands for an uplink transmission. The power level for the uplink transmission may be adjusted based on the combination of TPC commands. For example, the TPC commands may be considered together (e.g., added, averaged, etc.), the latest TPC command may be used, etc. In some cases, a change in TPC command for an uplink transmission (e.g., from a previous TPC command for the uplink transmission indicated via other DCI) may indicate a change in one or more transmission attributes for the uplink transmission. In some cases, a UE may receive a grant for a prioritized transmission, resulting in discontinuous transmission (DTX) of a previous transmission, which may result in TPC modification by the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a slot allocation to provide hybrid automatic repeat request (HARQ) acknowledgement (ACK) feedback to multiple transmission reception points (TRPs). For example, each TRP may be allocated at least one slot for HARQ-ACK feedback such that HARQ-ACK feedback for different TRPs may not be transmitted in a same slot. Additionally, the UE may determine a TRP-specific HARQ-ACK codebook for feedback transmissions to each TRP in their corresponding slots. In some cases, the UE may also determine TRP-specific uplink parameters for the feedback transmissions to each TRP. The UE may then transmit feedback to a TRP using a corresponding slot from the slot allocation and using the TRP-specific HARQ-ACK codebook and the TRP-specific uplink parameters.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify one or more first user equipments (UEs) that have been configured for grant-free transmissions on an allocation of resources. In some cases, the base station may then schedule an uplink transmission for a second UE on resources that overlap the allocation of resources. Accordingly, the base station may transmit a power adjustment indication (PAI) to the one or more first UEs to adjust a transmit power for uplink transmissions on the overlapping resources. In some cases, the PAI may include an indication of frequency-domain resources for the power adjustment indicated in the PAI, a specified time duration for the power adjustment indicated in the PAI, an indication of specific uplink transmissions to which the transmit power adjustment is to be applied, or a combination thereof.

Abstract: Wireless communications systems and methods related to hybrid automatic repeat request (HARQ) history feedbacks are provided. A user equipment (UE) receives one or more data blocks of a plurality of data blocks, each of the one or more data blocks received in one of a plurality of transmission occasions. The UE transmits an individual feedback for each of the one or more data blocks indicating whether the data block is received successfully. The UE transmits a feedback history report for one or more transmission occasions of the plurality of transmission occasions.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a resource allocation, from a resource set, for a response message using a resource allocation selection procedure. In some aspects, the user equipment may transmit the response message using the resource allocation and based at least in part on determining the resource allocation. In some aspects, the user equipment may determine, using an implicit resource mapping procedure and before a radio resource control connection establishment, a resource allocation for a redundancy scheme response message based at least in part on a remaining minimum system information (RMSI) value. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may be configured with periodic uplink grants that provide a number of repetitions and a redundancy version (RV) sequence for the repetitions. Prior to the start of an uplink grant period, the UE may determine a set of slots that are available for uplink transmissions in the uplink grant period. Based on the set of slots, the UE may determine a corresponding RV for repetitions of the uplink communication associated with each slot. The slots with uplink transmissions within the uplink grant period may be non-contiguous. Repetitions of an uplink communication may be configured to be transmitted across multiple uplink grant periods, which may be triggered based on a threshold value associated with the repetitions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling indicating a set of sidelink shared resources of a sidelink shared resource pool, a threshold quantity of mini-slot reservations for the set of sidelink shared resources, and an indication of a sidelink transmission mode of operation, where each slot of one or more slots of the set of sidelink shared resources may include multiple mini-slots. The UE may transmit to one or more sidelink UEs, sidelink control information that may include a reservation of a set of mini-slots of a first slot of the multiple slots, where the quantity of the set of mini-slots satisfies the threshold quantity of mini-slot reservations. The UE may transmit sidelink signaling to the one or more sidelink UEs, via the set of mini-slots according to the sidelink transmission mode of operation associated with the set of mini-slots.

Abstract: Methods, systems, and devices for wireless communication are described. In some cases, a sidelink user equipment (UE) operating in a power saving mode may identify a resource reservation configuration for communicating within a resource pool allocated for sidelink communications. The UE may operate in a first power state of the power saving mode during a sensing window. The sensing window may correspond to a resource selection window of the resource pool. The UE may transition, after the sensing window, from the first power state to a second power state that may consume more power than the first power state. The UE may identify a subset of resources of the resource pool in the resource selection window that are available for sidelink transmission by the UE based on transitioning between the first power state and the second power state.
