Embodiments include methods, performed by a user equipment (UE), for hybrid ARQ (HARQ) feedback in relation to multicast transmissions from a network node in a radio access network (RAN). Such methods include receiving, from the network node, first downlink control information (DCI) scheduling a first multicast transmission associated with the UE and determining a HARQ feedback mode for the first multicast transmission. Such methods also include, based on the first DCI, attempting to decode the first multicast transmission; and selectively transmitting HARQ feedback related to the first multicast transmission to the network node based on the determined HARQ feedback mode and on whether the attempt to decode is successful or unsuccessful. Embodiments also include complementary methods for a network node, as well as UEs and network nodes configured to perform such methods.

Systems and methods for implementing semi-persistent scheduling (SPS) transmission of periodic messages via one or more sidelinks are described. SPS for a sidelink groupcast may be activated and/or deactivated using SPS control signaling for the sidelink groupcast. SPS control signaling utilized for activating/deactivating SPS for a sidelink groupcast may include a SPS indicator (e.g., conveyed at least in part via SCI format 0-1 message), an activation/deactivation indicator (e.g., conveyed at least in part via SCI format 0-1 message and/or SCI format 0-2 message), and/or a configuration index (e.g., conveyed at least in part via SCI format 0-1 message and/or SCI format 0-2 message). Other aspects and features are also claimed and described.

A transmission or reception configuration method and a terminal are provided. The transmission or reception configuration method is performed by a terminal and includes: obtaining a transmission or reception configuration, where the transmission or reception configuration is used to indicate a first time domain range in which the terminal does not monitor a target object or a second time domain range in which the terminal monitors a target object.

Methods, systems, and devices for hybrid automatic repeat request (HARQ) codebook generation in mobile communication technology are described. An example method for wireless communication includes receiving, by a wireless device from a network node, a control message comprising one or more indicators corresponding to a plurality of control channels in a service of one or more services, and determining, based on the one or more indicators, a HARQ codebook for the one or more services, wherein the service further comprises a plurality of data channels corresponding to the plurality of control channels.

In an example, a User Equipment (UE) receives and/or detects a transmission of data from a network. The transmission of the data is addressed to a Group Radio Network Temporary Identifier (G-RNTI) for a Hybrid Automatic Repeat Request (HARQ) process. In response to receiving and/or detecting the transmission of the data, the UE (i) starts a first HARQ Round Trip Time (RTT) timer associated with the G-RNTI for the HARQ process, and (ii) starts a second HARQ RTT timer associated with a Cell Radio Network Temporary Identifier (C-RNTI) for the HARQ process. The UE starts a multicast retransmission timer for the HARQ process in response to expiry of the first HARQ RTT timer. The UE starts a unicast retransmission timer for the HARQ process in response to expiry of the second HARQ RTT timer. The UE receives and/or detects a first retransmission of the DL data addressed to the G-RNTI for the HARQ process. In response to receiving and/or detecting the first retransmission of the data, the UE (i) stops the multicast retransmission timer, and (ii) stops the unicast retransmission timer.

The base station may receive feedback pertaining to reception of each of the set of code blocks at each of the multiple UEs. The base station may generate, based on the feedback, a retransmission message that includes encoded data representative of a subset of code blocks of the set of code blocks and additional redundancy with respect to the subset of code blocks.

The UEs may combine the portion of the set of code blocks with the unsuccessfully decoded code blocks to create an updated combined versions of the code blocks. The UEs may decode the combined versions of the code blocks.
