Abstract: Disclosed are methods and systems for monitoring control channel candidates in a common search space (or a common search space set) in a wireless communication network. One of the methods is performed at a user equipment (UE). The method comprises: determining a first set of parameters for configuring a first set of monitoring occasions for the UE to monitor control channel candidates in a common search space (CSS); transmitting, to a network entity, an indication indicating the first set of parameters; and monitoring control channel candidates in the CSS during the first set of monitoring occasions.

Abstract: The present disclosure provides solutions to sidelink transmission/reception problems by preparing waveforms for multiple resource blocks (RBs) in a given bandwidth. Upon determining the availability of RBs or sets of RBs the apparatuses and methods of the present disclosure allow for dynamic determination and use of available sidelink frequencies. An apparatus may comprise a memory and at least one processor coupled to the memory and configured to transmit and/or receive sidelink data in at least one contiguous set of RBs within a bandwidth part (BWP) of an unlicensed frequency band, the BWP including a plurality of RB sets, wherein the SL data is transmitted and/or received in a waveform generated for at least one of the plurality of RB sets prior to a listen-before-talk procedure indicating an availability of the at least one contiguous set of RBs for transmission.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein relate to transmission of a multicast message via a common frequency resource (CFR) in a full duplex slot. The CFR may be positioned within the downlink bandwidth parts (BWP)s configured for a group of user equipments (UE)s such that each UE in the group may monitor for and receive the multicast message. The network may indicate the frequency position of the CFR to the group of UEs. The frequency resources (e.g., the resource blocks) configured for downlink for a UE may be different between half duplex slots and full duplex slots. The network and the UE may determine the active CFR for a full duplex slot based on the resources configured for the full duplex slot. The UE may monitor for and receive a multicast transmission in the active CFR in the full duplex slot.

Abstract: Methods, systems, and devices for wireless communication are described. A first user equipment (UE) may receive a control message that includes an indication to mute communications between the first UE and a second UE. The indication may be applicable to at least one communication link between the first UE and the second UE. The indication may include an identifier of the first UE, an identifier of the second UE, or an identifier of the at least one communication link. The first UE may receive the indication based on a power status of the first UE, a power status of the second UE, a reliability metric associated with the at least one communication link, or an interference metric associated with a network entity. Accordingly, the first UE may determine that the at least one communication link is muted for a time duration based on the indication.

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 communications are described. A user equipment (UE) may generate feedback messages according to a feedback codebook according to a feedback scheme indicating whether the UE is to include, or exclude, feedback information for physical downlink shared channels (PDSCHs) occurring prior to a bandwidth part (BWP) switch. For example, the UE may determine whether to include feedback information for any PDSCHs that occur prior to an uplink BWP switch for a UE that supports cell switching based on the cell in which the uplink BWP switch occurs, the cell in which the feedback message is scheduled for transmission (e.g., the same cell in which the PDSCHs occur, or a different cell), and a mode of PUCCH cell switching (e.g., dynamic or semi-static). The UE may also determine whether to send retransmissions of feedback information after a BWP switch.

Abstract: An apparatus for wireless communication is provided. The apparatus may be a network node. The apparatus receives a set of uplink transmissions from a set of user equipments (UEs) via a first resource of a non-orthogonal channel, wherein the apparatus is unable to decode the set of uplink transmissions. The apparatus transmits a retransmission request to a subset of the set of UEs. The apparatus receives a retransmission of a first uplink transmission in the set of uplink transmissions via a second resource of the non-orthogonal channel in response to the retransmission request. The apparatus decodes a second uplink transmission in the set of uplink transmissions based on at least the retransmission of the first uplink transmission.

Abstract: A method includes sending, by a first node to a second node during a first connection event, a request to change a current operation frequency, wherein the request is encoded in a first operation frequency. The method also includes sending, by the first node to the second node during the first connection event, a first packet encoded in a second operation frequency, where second operation frequency is different from the first operation frequency.

Abstract: Wireless communications systems, apparatuses, and methods are provided. A method of wireless communication performed by a first sidelink user equipment (UE) may include monitoring a first resource pool (RP) associated with a slot, monitoring a second RP associated with one or more sub-slots, wherein the second RP at least partially overlaps the first RP, receiving, from a second sidelink UE, an indicator indicating a selection of the first RP or the second RP, and receiving, from the second sidelink UE, a communication via the first RP or the second RP based on the indicator.

Abstract: Methods and apparatuses for facilitating avoidance of NSTR constraint violation caused by TDLS channel switching and link enablement in multi-link operation (MLO) in a wireless local area network. The methods include determining to switch a frequency channel used by a first tunneled direct link setup (TDLS) direct link from a first frequency channel to a second frequency channel, wherein the TDLS direct link is formed between a station (STA) of a non-access point (AP) multi-link device (MLD) and a corresponding peer STA, generating a TDLS channel switch notification message that includes an indication that the first TDLS direct link is switching from the first to the second frequency channel, and transmitting, to an AP MLD with which the non-AP MLD is associated, on an MLO link, the TDLS channel switch notification message, wherein MLO links are formed between STAs of the non-AP MLD and APs of the AP MLD.
