摘要： 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.

摘要： 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.

摘要： Systems, methods, and apparatuses for cross division duplex (XDD) operation in a wireless communication system are described herein. A user equipment (UE) is configured with one or more sub-bands (SBs) within a larger overall bandwidth (BW) (e.g., represented by a component carrier (CC), a bandwidth part (BWP), etc.), and that use uplink (UL)/downlink (DL) resource allocation(s) that may be different than the larger BW. Configurations for such SB-specific (SBS) arrangements that use guard bands (GBs) between SBs are discussed. Mechanisms for slot format indications (SFIs) within such SBs using either SBS DCI or cross-SB DCI are discussed. Mechanisms for providing SBS uplink resource for initial access (e.g., random access) using at least one initial UL BWP that is configured relative to one or more SBs and that may be used by XDD-capable UEs are discussed.

摘要： A sidelink transmission and an uplink transmission that is carrying a sidelink hybrid automatic repeat request (HARQ) are both scheduled for transmission in a shared time window. If a priority associated with the sidelink HARQ is considered to be higher than a priority associated with the sidelink transmission, then a higher priority is assigned to the uplink transmission, regardless of whether the uplink transmission contains other uplink data. Otherwise, if the uplink transmission does not carry other uplink data, then the higher priority is assigned to the sidelink transmission. Greater transmission resources are given to the transmission with the higher priority.

摘要： An example method for wireless communication includes: configuring a wireless device to access a wireless network using a set of at least three components carriers (CCs); dividing the at least three component carriers into groups of component carriers based on whether the component carriers share a span pattern and a starting span for monitoring a Physical Downlink Control Channel (PDCCH) of each component carrier; determining a number of non-overlapping control channel elements (CCE) to monitor for each group of component carriers; and configuring the wireless device to monitor the non-overlapping CCEs based on the determined number to monitor for each group.

摘要： 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.

摘要： Techniques discussed herein can facilitate successful decoding of Physical Downlink Shared Channel (PDSCH) based on a reduced number of retransmissions. Based on a given PDSCH, embodiments discussed herein can communicate feedback (e.g., Hybrid Automatic Repeat reQuest (HARQ) feedback, Channel State Information (CSI) feedback) that indicates an amount of additional information that can allow a User Equipment (UE) to successfully decode the PDSCH. In some embodiments, the feedback can indicate a requested Redundancy Version (RV) sequence that can allow the UE to successfully decode the PDSCH. In other embodiments, the feedback can indicate the amount of additional information, based on which a receiving Base Station (BS) can select a RV sequence.

摘要： Methods and apparatus are provided for a UE to determine a UL spatial relation for an UL transmission in response to an unknown UL spatial relation switch. The UE may determine whether the UL spatial relation is based on an SRS transmission in UL, a CSI-RS in DL, or an SSB in the DL. If the UL spatial relation is based on the SRS transmission, the UE may select the UL spatial relation for the UL transmission corresponding to a Tx beam of the SRS transmission. If the UL spatial relation is based on the CSI-RS or the SSB, the UE may select the UL spatial relation for the UL transmission based on whether the unknown UL spatial relation switch s due to a corresponding resource for beam training not being configured by a communication network or a corresponding beam information being expired.
