摘要： Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for using layer one (L1) or layer two (L2) signaling to indicate a primary cell (PCell) or primary secondary cell (PSCell) to a user equipment (UE). The use of L1 or L2 signaling to indicate a PCell or PSCell may be referred to as L1 or L2 mobility and may lower the latency at the UE associated with transitioning to communicating with the PCell or PSCell. A UE may receive radio resource control (RRC) signaling from a base station indicating a set of cells configured for L1 or L2 mobility and indicating a list of candidate cells for a PCell or PSCell. The UE may then receive L1/L2 signaling from the base station identifying the PCell or indicating activation of the PSCell.

摘要： Certain aspects of the present disclosure relate to wireless communications, and more particularly, techniques for an enhanced paging procedure. A method that may be performed by a user equipment (UE) includes detecting, during a paging occasion (PO), at least one downlink control information (DCI) that indicates a paging message and additional downlink signals and using the additional downlink signals to enhance processing of the paging message.

摘要： Methods, systems, and devices for wireless communications are described in which a user equipment (UE) of a group of UEs may communicate with other members of the group to provide data or other information via sidelinks. The UE may transmit a groupcast sidelink request to the base station. After receiving the sidelink request, the base station may send a sidelink grant (e.g., transmit or receive grant) in downlink control information (DCI) to the UEs in the sidelink groupcast communications group. The sidelink grant may include information for each hop such as which UEs are going to transmit or receive, the reception or transmission beams of the UEs, time and frequency resources, or the data to forward or relay. In some examples, a UE may relay information to other UEs in the sidelink groupcast communications group.

摘要： Methods and apparatuses for transmitting and detecting channel reservation preamble in a NR shared spectrum are described. An aspect may include determining whether a first reservation preamble of a first operator is received on a first time slot of multiple time slots of a downlink channel from a first network entity, and transmitting a second reservation preamble of the first operator on an uplink channel to the second network entity. Another aspect may include generating a first reservation preamble of a first operator based on at least one of a compressed representation in a signal space, a basis function of the signal space, or a CAZAC sequences; and transmitting, on a first timeslot of multiple time slots of a downlink channel, the first reservation preamble of the first operator to at least a UE.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a source UE, a first sidelink communication. The UE may generate a transmit power control command based at least in part on a signal to interference noise ratio measurement associated with the first sidelink communication. The UE may transmit, to control a transmit power for a second sidelink communication, the transmit power control command to the source UE. Numerous other aspects are provided.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from an entity of a non-terrestrial network (NTN), a system information block (SIB) that indicates information relating to one or more NTN SIBs that are to include at least one of ephemeris information or feeder link timing advance information. The UE may receive, from the entity of the NTN, the one or more NTN SIBs based at least in part on the information. Numerous other aspects are described.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify at least one of a control resource set zero (CORESET0) field or a search space zero (SS0) field in a master information block (MIB). The UE may identify, based at least in part on whether the UE is a reduced capability UE, at least one of: a CORESET0 configuration associated with a first value indicated in the CORESET0 field, or an SS0 configuration associated with a second value indicated in the SS0 field. Numerous other aspects are provided.

摘要： Techniques for wireless communications are described. A user equipment (UE) may receive downlink control information (DCI) scheduling sidelink transmissions in one or more sets of multiple transmission time intervals (TTIs) over a shared spectrum. The UE may perform a listen-before-talk (LBT) for one or more of the TTIs in the one or more sets of multiple TTIs, and the UE may transmit, to a base station, an indication of results of the LBT performed for the one or more TTIs. Because the UE may provide the results of the LBT to the base station, the base station may be able to schedule sidelink transmissions from the UE based on the results of the LBT. As such, the UE may experience increased throughput in sidelink communications since the scheduling at the base station may be improved.

摘要： Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may be scheduled for communicating a first message over a first communication link with a base station and a second message over second communication link with a second UE. The first UE may select to communicate using the first communication link or the second communication link based on one or more prioritization rules that may involve the priority of the first message and the second message. The first UE may identify a mapping between the priority of the first message and the priority of the second message that may enable a comparison of the priorities of the first message and the second message. The first UE may select to communicate using the communication link of the message associated with the higher priority.

摘要： This disclosure provides systems, methods, and devices for wireless communication that support reduced bandwidth devices and particularly, allocation of more than three orthogonal frequency division multiplexing (OFDM) symbols in the time domain to a control resource set (CORESET). In a first aspect, a method for wireless communication includes receiving, from a base station at a user equipment (UE), a first message that indicates a CORESET configuration. The CORESET configuration allocates more than three OFDM symbols in the time domain to a CORESET. The method further includes monitoring a set of time and frequency resources to receive a second message from the base station at the UE. The set of time and frequency resources have the CORESET configuration. Other aspects and features are also claimed and described.
