The apparatus can select one or more rows or one or more columns in a DFT matrix, the one or more rows being even-numbered rows in the DFT matrix and the one or more columns being even-numbered columns in the DFT matrix. The apparatus can also determine an orthogonal matrix based on the one or more rows or the one or more columns in the DFT matrix, the orthogonal matrix having a size of (M×N)×(M×N) with M×N rows and M×N columns. Also, the apparatus can determine a codebook based on the orthogonal matrix, the codebook including a plurality of codepoints. The apparatus can also transmit at least one signal including a first codepoint of the plurality of codepoints in the codebook.

Abstract: An apparatus may be configured to determine that a first random access channel (RACH) procedure with a base station is unsuccessful. The apparatus may be further configured to transmit, after determining that the first RACH procedure is unsuccessful, a preamble message for a second RACH procedure with the base station. A second configuration for the second RACH procedure may be different from a first configuration for the first RACH procedure. Another apparatus may be configured to receive a preamble message from a UE for a second RACH procedure having a second configuration different from a first configuration for a first RACH procedure. The other apparatus may be further configured to determine that the first RACH procedure with the UE is unsuccessful.

Abstract: Aspects described herein relate to receiving, from a base station, a downlink communication indicating resources scheduled for one or more repetitions of a downlink control channel, receiving, from the base station, the one or more repetitions of the downlink control channel, and combining the one or more repetitions of the downlink control channel to decode the downlink control channel. In another aspect, the network can transmit, to a user equipment (UE), a downlink communication indicating resources scheduled for one or more repetitions of a downlink control channel, and transmitting, to the UE, the one or more repetitions of the downlink control channel over the resources.

Abstract: Aspects of the present disclosure relate to a technique for determining quasi co-location (QCL) and/or transmission configuration information (TCI) state assumption information for a dynamic control resource set (CORESET). A user equipment (UE) may receive and/or detect a downlink control information (DCI) that schedules at least one dynamic CORESET and indicates a TCI state from a list of one or more TCI states for the dynamic CORESET. The UE may apply the indicated TCI state for processing physical downlink control channel (PDCCH) transmissions in the dynamic CORESET when one or more conditions are met.

Abstract: A data pipeline between a base station and a user equipment (UE) may be formed via a relay UE. In this regard, a base station is configured to send a joint grant to the first UE, the joint grant including a first resource assignment for transmission of data via a first communication link between the base station and the first UE, and a second resource assignment for transmission of data via a second communication link between the first UE and a second UE. The first and second communications link may form a downlink pipeline for transmitting data from the base station to the UE. The first and second communications link may be used to transmit uplink data in parallel from the first UE to the base station.
