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

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.

Systems and methods for PTRS and DMRS port association for transmission of PUSCH on multiple beams

Techniques, described herein, include solutions for enabling PC parameters and beam selection regarding mixed traffic, including a PC parameter set selection based on unified transmission configuration indicator (TCI) states, reporting power headroom (PHR) based on PC parameter sets, and beam selection based on traffic types associated with different TCI states.

Systems, methods, and devices for power control and beam selection in mixed traffic

This disclosure relates to techniques for aligning wireless device and cellular network expectations and behavior in conjunction with neighbor cell measurements in a wireless communication system. A wireless device may determine that a reference signal is configured for a neighbor cell measurement when communication with the serving cell is also configured. The wireless device may determine whether the reference signal for the neighbor cell measurement is configured with same or different subcarrier spacing as the communication with the serving cell. The wireless device may select one or more of the reference signal for the neighbor cell measurement or the communication with the serving cell to receive based at least in part on whether the reference signal for the neighbor cell measurement is configured with same or different subcarrier spacing as the communication with the serving cell.

Wireless device scheduling availability during neighbor cell measurements

Apparatuses, systems, and methods for a wireless device to perform beam management procedures with a base station. A wireless device in communication with a 5G base station may perform measurements and determine constraints relevant to beam selection. The device may select a recommended beam based on the measurements and constraint(s) and indicate the recommended beam to the base station. A recommended uplink beam may not correspond to a recommended downlink beam.

Beam management without beam correspondence

A user equipment (UE) is configured to operate as a relay UE between a remote UE and a base station. The relay UE receives, from an originating device, a data packet for relay to a recipient device, determines that the relay of the data packet to the recipient device has failed and sends, to the originating device, a transmission including the data packet, wherein the transmission comprises an indication that the data packet is being returned to the originating device.

Data transfer during mobility in layer 2 relay

A method and apparatus configuring default beams are described. In some embodiments, the method of wireless communication at a User Equipment (UE) comprises: receiving, from a base station, configuration information for configuring a default beam for the physical downlink shared channel (PDSCH) to use on condition that an offset between reception of downlink control information (DCI) in the scheduling physical downlink control channel (PDCCH) and corresponding PDSCH is less than a threshold and at least one Transmission Configuration Indicator (TCI) states includes spatial receiving parameters for configuring a quasi-co-location; configuring, by the UE, a default beam configuration for the PDSCH based on the configuration information and a monitored control resource set (CORESET) with a lowest CORESET identifier (ID) from among a set of CORESETs in a latest slot in a same bandwidth part (BWP), wherein at least one CORSET of the set of CORESETs includes more than one TCI state; and receiving a transmission using the default beam.

Default beams for PDSCH, CSI-RS, PUCCH and SRS

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.

Methods for indicating the availability of the reference signal for idle/inactive user equipments

In 5G/New Radio (NR), sidelink communication refers to a channel for communications directly between devices, e.g., user equipment (UEs), without use of traditional uplink or downlink communication channels. Sidelink Control Information (SCI) is separated into two stages (i.e., SCI stage 1 and SCI stage 2) before being transmitted to configure a user device. A method for configuring sidelink communications for a wireless device includes: obtaining SCI Stage 2 payload information; attaching and distributing cyclic redundancy check (CRC) information to the payload information; performing encoding and rate matching (RM) on the payload information; scrambling the encoded and rate matched payload information; performing modulation on the scrambled payload information; determining a resource mapping for the modulated payload information, wherein the modulated payload information is aggregated across two or more slots (e.g., using different processing operations for at least two slots); and transmitting the modulated payload information according to the determined resource mapping.
