Apparatuses, systems, and methods for a wireless device and a cellular base station to support common analog beam steering for band groups. The wireless device may provide an indication of analog beam steering capability of the wireless device to the cellular base station. For example, the wireless device may support a limited number of analog beams for each of one or more band groups. The cellular base station may select beam configuration information for the wireless device based at least in part on the indication of analog beam steering capability of the wireless device. This may include selecting a common beam for multiple component carriers for the wireless device based on the wireless device's analog beam steering capability. The cellular base station may provide the beam configuration information to the wireless device.

Common analog beam steering for band groups

Apparatuses, systems, and methods for providing downlink control for non-coherent joint transmission. A cellular base station may provide downlink control information associated with a non-coherent joint transmission downlink data communication to a wireless device, which may receive the downlink control information. The downlink control information may be provided as a single downlink control information including scheduling information for two data streams of the non-coherent joint transmission data communication, or a portion of a multi-stage downlink control information transmission. The wireless device may receive the non-coherent joint transmission downlink data communication based at least in part on the downlink control information.

Downlink control for non-coherent joint transmission

To accommodate a mix of high frequency carriers and lower frequency carriers, a protocol stack may include a radio link control (RLC) entity that allows configuration of status reporting control parameters on per carrier, or per subcarrier spacing. Alternatively, a protocol stack may include two RLC entities, one for handling high frequency carriers, and another for handling lower frequency carriers. (High frequency carriers and lower frequency carriers may be distinguished based on a frequency threshold.) Furthermore, a user equipment may transmit (to the network) an indication of its L2 buffer size. The network may configure the UE and/or control scheduling, to ensure the UE's L2 buffer does not overrun. Alternatively, the UE may indicate that it can support a percentage of a maximum buffer size. The network may configure the UE and/or control scheduling so that the UE's buffer occupancy does not exceed the percentage.

Handling high data rates in protocol stack when using high frequency spectrum

A base station may transmit a message to a group of user equipments (UEs), directing the UEs to change their respective bandwidth parts (BWPs). For each of the UEs of the group, the message may include a corresponding new BWP. In response to receiving the message, each UE of the group may switch to the corresponding new bandwidth part. The message may be transmitted as part of a group common DCI message. The UE may signal its required minimum guard band size to the base station. Alternatively, the UE may respond to the message with an acknowledgement message. The base station may configure a virtual common downlink BWP for the group of UEs. The UEs drop transmission/reception repetitions that occurs during its BWP switch delay period.

Joint bandwidth part switching for a group of UEs

Methods, systems, and devices for wireless communications are described. SSB based inter-frequency measurements may include configuring a UE to perform inter-frequency measurements without measurement gap within a measurement window, and applying scheduling restrictions to prioritize the inter-frequency measurements over uplink transmissions within the measurement window. The measurement window includes an SMTC window duration. Measurement resource sharing or restriction is described for SSB based inter-frequency measurement objects without measurement gap.

Methods and apparatus for scheduling availability/restriction and measurement sharing for SSB based inter-frequency measurement without measurement gap

A user equipment (UE) is configured to receive a measurement configuration from a serving cell, wherein the measurement configuration comprises event configuration associated with radio resource management (RRM) relaxation, perform measurements of the serving cell, transmit a measurement report to the serving cell and receive an indication from the serving cell that RRM relaxation for radio resource control (RRC) connected mode is enabled at the UE.

Radio resource management relaxation for radio resource control connected mode

Provided is a method for a user equipment (UE), comprising: performing, based on a command for a handover (HO) with a primary secondary cell (PSCell), an HO of a target primary cell (PCell) and an addition of a target PSCell; and adjusting a radio frequency (RF) for the HO of the target PCell according to a reference signal (RS) occasion for the HO of the target PCell, and an RF for the addition of the target PSCell according to an RS occasion for the addition of the target PSCell.

Technologies for handover procedures

Aspects are presented herein of apparatuses, systems, and methods for secondary cell group (SCG) addition. A wireless device may establish communication with a first base station that is comprised in a master cell group (MCG) and a second base station that is comprised in the SCG. The wireless device may maintain timing advance (TA) parameters for performing uplink communication with the second base station. The wireless device may perform a plurality of signal quality measurements after receiving an indication to deactivate the SCG. The wireless device may determine whether to reuse the TA parameters for communicating with the second base station after receiving an indication. The determination may be based on comparing one or more signal quality measurements of the second base station to one or more signal quality thresholds.

Uplink timing synchronization maintenance in secondary cell group

A user equipment (UE) associated with a wireless communication system is disclosed. The UE comprises one or more processors configured to process a service configuration signal received from a base station associated therewith. In some aspects, the service configuration signal comprises an indication of one or more service configurations associated with a data transmission that are allowed to be transmitted by the UE during an INACTIVE state of the UE. The one or more processors is further configured to determine the one or more service configurations associated with the data transmission that are allowed to be transmitted by the UE during the INACTIVE state of the UE, based on processing the service configuration signal.

Access control of user equipments for inactive direct transmissions

A user equipment (UE) is configured to receive a sounding reference signal (SRS) configuration from a network, wherein the SRS configuration comprises a 6 port SRS configuration. The UE is also configured to transmit, from each of the 6 ports, SRS on one or more SRS resources corresponding to the SRS configuration.

Codebook and non-codebook support for SRS with 6 ports

Methods and systems are disclosed for a UE to manage and measure intra-cell cross link interference (CLI) when served by a base station operating in full-duplex FDD. The signaling may indicate to a victim UE resources to measure to determine the level of CLI from aggressor UEs. The resources used for the CLI measurement may be resources not scheduled by the base station for use by the victim UE for downlink reception, but are scheduled for use by the aggressor UEs for transmitting uplink traffic or for transmitting reference signals used to characterize the uplink channel. The victim UE may report the CLI measurements to the base station for the base station to adjust scheduling of downlink resources to the victim UE. In one aspect, the signaling from the base station may indicate to the victim UE the locations of scheduled downlink symbols that may potentially be impacted by CLI.

Intra-cell UE-to-UE cross link interference management at full-duplex operation

This disclosure relates to techniques for performing multi-transmission and reception point operation in a wireless communication system. A transmission control indication state may be indicated for future monitoring of a control channel, e.g., using one or more rules. The indicated state may be used to provide and receive control information for performing multi-transmission and reception point operation.
