Abstract: Systems and methods used by reduced sensing user equipment (UE) (relative to a full sensing UE) are disclosed herein. A UE performing partial sensing may use knowledge of resource reservation periods for a resource pool of one or more resources to reduce sensing as compared to the full sensing case. A UE performing resource re-evaluation and/or resource pre-emption may use one or more sensing windows that are relatively smaller than windows used in the full sensing case to reduce sensing. A UE performing prioritized resource selection may use a sensing window to determine availability of resources within it prioritized resource selection window with a high reliability, thereby reducing the need to spend power on other sensing methods (which may include full sensing methods). Combinations of these embodiments are also contemplated.

Abstract: Techniques, described herein, include solutions for enabling power control processes within a wireless telecommunications network. A base station may operate in a full duplex mode by simultaneously sending and receiving signals to user equipment (UEs). Power control processes may be implemented to eliminate or mitigate signal interference, such as self-interference at the base station or cross link interference (CLI) at a UE. The power control processes may include causing UEs to transmit signals, a UE and/or the base station measuring interference and causing the base station and/or UEs to modify transmission power to address the signal interference.

Abstract: A user equipment (UE) comprising a processor configured to perform the operations that determines an uplink (UL) slot is described. In exemplary embodiments, the UE receives, from a base station, a scaling factor through a first Radio Resource Control (RRC) signal. The UE may further determines an offset through a second RRC signal. In addition, the UE may receive from the base station, downlink control information (DCI) that includes an indication of an initial time gap. Furthermore, the UE may calculate a new time gap by at least applying the scaling factor to the initial time gap and determine a slot of uplink transmission based on at least the new time gap and the offset.

Abstract: A method for wireless communication includes: receiving, at a base station: (1) a capability report for each of a plurality of antenna panels of a first user device; and (2) an initial antenna panel index for the first user device; transmitting, to the first user device, configuration information corresponding to each antenna panel of the plurality; selecting first configuration information corresponding to the antenna panel with the initial antenna panel index; and receiving a first uplink transmission from the first user device, wherein the first user device uses a selected first antenna panel corresponding to the initial antenna panel index and the first configuration information corresponding to the selected first antenna panel. In other aspects, rather than initially transmitting configuration information corresponding to each antenna panel, the base station may transmit the configuration information for each panel as it is selected by the first user device for an uplink transmission.

Abstract: Systems and methods using control signaling for uplink frequency selective precoding at a user equipment (UE) are disclosed herein. A base station may indicate a transmission rank indicator (TRI), a wideband transmission precoder matrix indicator (TPMI), and one or more subband TPMI(s) to the UE. The base station may indicate, to the UE, whether to use the wideband TPMI or a subband TPMI to precode a physical uplink shared channel (PUSCH) transmission from the UE to the base station. The UE then precodes (and transmits) the PUSCH accordingly. Methods of UE application of the indicated subband TPMI(s) to subbands of the bandwidth in which a PUSCH may be transmitted are described. Methods accounting for a UE capability as to non-coherent, partial-coherent, and/or coherent precoding are described. Methods of assigning TPMI(s) to subbands in view of multiple transmission reception point (TRP) use by the UE for UE transmission are described.

Abstract: A method and apparatus for configuring default beams by a base station are disclosed and include determining configuration information that specifies a default Physical Uplink Control Channel/Sounding Reference Signal (PUCCH/SRS) beam and pathloss Reference Signal (RS) for a User Equipment (UE), and transmitting to the UE the configuration information identifying a default configuration for the default PUCCH/SRS beam and pathloss reference signal (RS). The default PUCCH/SRS beam and pathloss RS configured by the UE are based on the configuration information and a monitored Control Resource Set (CORESET) with a lowest CORESET identifier (ID) selected among a set of CORESETs in a same Bandwidth Part (BWP). The monitored CORESET selected may include two transmission configuration indicator (TCI) states. The default PUCCH/SRS beam and pathloss RS configured is based on a TCI first among the two TCI states or a TCI state with a lowest ID among the two TCI states.

Abstract: Various techniques are presented to improve phase tracking reference signal (PTRS) performance with respect to very high frequency communications. According to some embodiments, increased power boosting may be applied to improve PTRS performance, while still keeping power spectral density (PSD) within ETSI Broadband Radio Access Networks (BRAN) limits. In some cases, the power boosting may be semi-static and/or dynamic. In other embodiments, the improved performance may be achieved by dynamically changing time and/or frequency density of the PTRS. In other embodiments, a multi-port configuration may be used for the downlink PTRS. In other embodiments, one or more PTRS configurations may be determined per SCS and/or frequency band, e.g., based on traffic type, channel priority, parameters signaled in the slot format indication (SFI), etc. In other embodiments, common phase error (CPE) estimates may be obtained for those OFDM symbols without PTRS by interpolating the available PTRS estimates in the time domain.
