According to an embodiment of the disclosure, a method of operating a user equipment (UE) for estimating a channel based on a physical uplink shared channel (PUSCH) transmitted repetitively may include receiving, from a base station (BS), repetitive transmission configuration information for repetitively transmitting a PUSCH; receiving, from the BS, frequency hopping configuration information including configuration information for a hopping interval between a plurality of frequency resources for transmitting the PUSCH; and repetitively transmitting the PUSCH to the BS while performing frequency hopping at the hopping interval based on the repetitive transmission configuration information and the frequency hopping configuration information.

A method for listen-before-talk random access with adaptive energy detection threshold selection is executed by a device. Component units, such as code block groups (CBGs) in a transport block are determined to be retransmitted through a contention-based random access operation. A component unit based energy detection threshold (EDT) is selected. The EDT is associated with the component units determined to be retransmitted. The selected component unit based EDT is used to perform energy detection in an initial contention-based random access operation.

Apparatus and methods are provided for group scheduling configuration and uplink HARQ configuration for the NR multicast services. In one novel aspect, the UE receives broadcasts the SIB message related to multicast transmission, receives multicast control information via RRC message, and configures the uplink HARQ feedback. In one embodiment, the SIB message includes control Resource Set and/or search space for MB-RNTI scramble. The multicast control information includes control Resource Set and/or search space within the MTCHinfolist G-RNTI scramble. The multicast control information includes one or more elements including MTCH index, uplink HARQ feedback request to inform the concerned UE(s) the HARQ feedback is disabled or enabled, the timing information between PDSCH and the uplink PUCCH feedback resource, the option of HARQ based feedback, one or a set of PUCCH resource or PUCCH resource instance, and an MTCH retransmission timer.

This application discloses an information feedback method, a resource scheduling method, a terminal, and a network device. The information feedback method includes: performing HARQ-ACK feedback for multicast downlink transmission and unicast downlink transmission in one time unit.

A channel monitoring method is provided. The method comprises: during the duration of skipping physical downlink control channel (PDCCH) monitoring, if a terminal device sends first information, the terminal device resuming PDCCH monitoring. Further disclosed in the present application are another channel monitoring method, an electronic device, and a storage medium.

A terminal according to one embodiment of the present invention determines and reports a specific codebook-based HARQ-ACK on the basis of the result of receiving a plurality of PDSCHs, and, on the basis of a first-type codebook-based HARQ-ACK having been set for scheduling of the plurality of PDSCHs, the terminal can perform first start symbol and length indicator value (SLIV) pruning on the basis of a set of the SLIVs of PDSCHs, which can be potentially scheduled on each slot of a bundling window determined on the basis of a plurality of candidate PDSCH-to-HARQ feedback timing values, and perform second SLIV pruning on the basis of a set of the SLIVs of PDSCHs, which can be potentially scheduled even on at least one slot that does not belong to the bundling window.

Methods, systems, and devices for wireless communication are described. A first wireless device may establish a sidelink communications link with a second wireless device. The first wireless device may transmit, to the second wireless device, an indication of a capability to support a configuration for phase continuity between multiple physical channel transmissions of the sidelink communication link. The first wireless device may transmit one or more physical channel transmissions, which each may be associated with a set of one or more demodulation reference signals (DMRSs) to the second wireless device in accordance with the indicated configuration for phase continuity between the physical channel transmissions. The second wireless device may determine channel parameters associated with the one or more physical channel transmissions based on a joint channel estimation associated with the one or more sets of DMRSs.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may receive first downlink control information (DCI) indicating a first redundancy version (RV) index value associated with a hybrid automatic repeat request (HARD) process. The mobile station may transmit, based at least in part on receiving the DCI indicating the first RV index value, data using a second RV index value, the second RV index value being different from the first RV index value. Numerous other aspects are described.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a relay user equipment (UE) may receive, from a base station, a downlink control information (DCI) message scheduling a first transmission between a source node and the relay UE and a second transmission between the relay UE and a destination node. The UE may transmit, to the base station, at least one of: feedback regarding at least one of the first transmission or the second transmission, or the second transmission. Numerous other aspects are described.

Methods, systems, and devices for wireless communications are described. Specifically, techniques that enable a base station to send a feedback message to a user equipment (UE) indicating a quality of uplink continuity are described. The base station may observe uplink communications received from the UE to determine a level of uplink continuity associated with the UE. Based on the measurements, the base station may transmit a feedback message indicating one or more measurements corresponding to the performance of the UE in maintaining uplink continuity. By utilizing techniques for indicating the quality of uplink continuity to the UE, the UE may address uplink continuity mismatches, which may increase overall network efficiency and improve channel estimations.
