Provided is a method for a user equipment (UE). The method comprises acquiring a downlink control information (DCI) configured for multiple-physical downlink shared channel (PDSCH) scheduling; determining, based on the number of PDSCHs scheduled by the DCI, whether a codebook group (CBG)-based operation is enabled for the scheduled PDSCHs; and determining, based on the number of PDSCHs scheduled by the DCI, a format of the DCI.

Codebook group-based operation with multiple-physical downlink shared channel scheduling

A cellular base station (BS) which determines an aperiodic sounding reference signal (SRS) triggering offset configuration specifying an offset between an aperiodic SRS trigger received by a user equipment (UE) and transmission of the SRS by the UE. The cellular base station may determine that the SRS triggering offset should be adjusted. In response, the cellular base station may transmit signaling to the UE specifying a new value for the aperiodic SRS triggering offset. The new SRS triggering offset value may be partly based on a minimum timing offset for the UE and may be contained in a medium access control (MAC) control element (CE) or in downlink control information (DCI). Additionally, the new triggering offset value may be applicable for a plurality of component carriers or bandwidth parts. The cellular base station may also determine a new triggering offset value due to conflicts regarding the AP-SRS transmission.

Dynamic configuration of aperiodic sounding reference signal offsets in cellular communications systems

A user equipment (UE) is connected to a special cell (SpCell) that is configured to schedule the SpCell and a secondary cell (SCell) that is configured to schedule the SpCell. The UE determines a number of blind decodes (BDs) and a number of control channel elements (CCEs) that may be configured for the SpCell and monitors a physical downlink control channel (PDCCH) for downlink control information (DCI) scheduling the SpCell that is transmitted by the SpCell and DCI scheduling the SpCell that is transmitted by the SCell.

Enabling multiple cells to schedule a special cell

Some aspects of this disclosure relate to apparatuses and methods for implementing a beam pairing procedure between a transmission UE and a receiver UE. The transmission UE and the receiver UE can configure a set of beam patterns to be used in the beam pairing procedure. The set of beam patterns can include one or more transmission beams of the UE, and one or more receiving beams of the receiver UE. The transmission UE can transmit one or more sidelink reference signals to the receiver UE, and the receiver UE can perform signal strength measurements of the one or more sidelink reference signals. Based on the signal strength measurements, either the transmission UE or the receiver UE can make the selection of the transmission beam and the corresponding receiving beam for the beam pairing procedure.

Mechanisms for user equipment beam pairing on sidelink communication

Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for support mobility in a wireless network for user equipments (UEs) with varying capabilities. A UE can receive a first system information from a serving base station, where the first system information includes a UE capability condition associated with a neighbor base station, and determine whether a UE capability meets the UE capability condition associated with the neighbor base station. When the UE capability condition is met, the UE can determine whether a first measurement of a first reference signal received from the serving base station and a second measurement of a second reference signal received from the neighbor base station satisfy a threshold condition. When the threshold condition is met, the UE can obtain a second system information from the neighbor base station, indicating the UE has performed handover to the neighbor base station.

Mobility support for user equipments with varying capabilities in a wireless network

The present application relates to devices and components including apparatus, systems, and methods providing transmission power controls in support of expanding a network coverage. In an example, a device is configured to expand the network coverage and establishes multiple wireless links between a base station and a user equipment (UE). The device can be network-controlled, whereby such controls can include adjusting the transmission power used by the device to transmit on at least one of such wireless links.

Power control for transmission on one or more links

Inter-cell beam management and inter-cell multiple transmission and reception point (multi-TRP) operation may include decoding a cell-specific reference signal (CRS) pattern list configuration received from a base station. The CRS pattern list configuration may include one or more CRS pattern lists. Each of the one or more CRS pattern lists correspond to one or more cells of a plurality of cells configured by the base station. Beam management associated with the plurality of cells may be performed based on the CRS pattern list configuration.

Rate matching and beam measurement for inter-cell beam management and inter-cell multi-TRP operation

Techniques discussed herein can facilitate the use of reference signals in active TCI switching. One example aspect is a user equipment (UE), comprising: a memory interface; and processing circuitry communicatively coupled to the memory interface and configured to: receive a physical downlink shared channel (PDSCH) message that includes an activation command indicating a target transmission configuration indicator (TCI) state; decode the activation command within a decoding period, where the decoding period is a time period allocated for the UE to decode the activation command; receive a TCI resource where the TCI resource is a reference signal; perform time and frequency tracking associated with the target TCI state according the TCI resource; and switch to the target TCI state after performing time and frequency tracking.

Reference signals in active TCI switching

Systems and methods for associating phase tracking reference signal (PTRS) and demodulation reference signal (DMRS) ports for multi-beam physical uplink shared channel (PUSCH) transmissions are described herein. A base station may provide, to a user equipment (UE), PTRS and DMRS port associations for the multiple beams on which the PUSCH is transmitted. In some cases, a 2-bit downlink control information (DCI) field may be used to alternatively provide single beam or multiple beam PTRS and DMRS port associations to a UE. For non-codebook (NCB) based transmissions, the UE may alternatively determine PTRS and DMRS port associations for multiple beams independently of any PTRS and DMRS port association indicated in DCI.

An approach to providing an indication of the availability of tracking reference signal (TRS) and/or channel state information reference signal (CSI-RS) occasions. Channels for carrying the indication include system information block (SIB) signaling, paging physical downlink control channel (PDCCH), and paging early indications. Various approaches are described that provide the information, including a number of bitmap approaches, a hierarchical informational approach, a dynamic signal indication that carries configuration indices. Additional approaches are described that reduce unnecessary overhead by specifying certain reference signal (RS) occasions as being available.
