Abstract: Aspects for MAC-CE duplication for packet repetition in uplink and downlink are disclosed. In one particular aspect a method of wireless communication includes receiving, by a user equipment (UE), a message including a component carrier (CC) identifier (ID) for a particular Medium Access Control (MAC) control element (MAC-CE). The method also includes receiving, by the UE, a first MAC-CE via a first CC of a plurality of CCs, and receiving, by the UE, a second MAC-CE via a second CC of the plurality of CCs. The CC ID included in the message corresponds to a CC ID for the second MAC-CE. The method further includes combining, by the UE based on the CC ID for the second MAC-CE, a first signal corresponding to the first MAC-CE and a second signal corresponding to the second MAC-CE to generate a combined signal for decoding.

Abstract: Methods, systems, and devices for wireless communications are described. In some communications systems, interference may impede signaling between a base station and a target user equipment (UE) such that a base station may identify a donor UE to relay communications to the target UE. The donor UE may receive a coded data packet from the base station, and may identify a radio network temporary identifier (RNTI) scrambling code for the packets addressed to the target UE. In cases where the donor UE identifies that the packet has an RNTI scrambling code associated with the target UE, the donor UE may forward the coded data packet to the target UE base on the RNTI scrambling code. Such early detection of data packets addressed to the target UE may allow for the UE to forward a data packet without fully decoding the packet.

Abstract: Methods and devices for discontinuous reception signaling for wireless communications systems are described. A base station may determine a semi-persistent scheduling (SPS) configuration and a discontinuous reception configuration (DRX) associated with the semi-persistent scheduling (SPS) configuration for a user equipment (UE). The base station may transmit the SPS configuration to the UE. The SPS configuration may indicate one or more DRX parameters for the DRX configuration. A UE may receive the semi-persistent scheduling configuration from the base station. The UE may identify one or more DRX parameters for the discontinuous reception configuration based on the SPS configuration. The UE may monitor a downlink control channel in accordance with the DRX configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, information that indicates a resource allocation for a downlink transmission and an uplink resource for transmission of a hybrid automatic repeat request (HARQ) codebook.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify uplink control information to be transmitted using a first carrier of a carrier group associated with a cell group. The UE may select a second carrier of the carrier group to transmit the uplink control information based at least in part on a type of uplink control information to be transmitted, a priority level associated with the uplink control information, a timing for transmission of the uplink control information with respect to an associated downlink transmission, or a combination thereof. The UE may transmit the uplink control information to one or more cells in the cell group using the second carrier.
