Abstract: Methods and apparatuses are provided for uplink MIMO transmissions in a wireless communication system. In some particular aspects, an E-TFC selection process for selecting a transport format combination for an uplink MIMO transmission may take certain steps in the case that a UE is power- or buffer-limited. For example, in a rank 2 transmission, non-scheduled data is allocated only to the primary stream. If the allocated non-scheduled data is less than the determined primary stream transport block size, scheduled data is allocated to the primary stream in an amount not to exceed the determined primary stream TBS. Finally, scheduled data is allocated to the secondary stream in an amount not to exceed the determined secondary stream TBS.
Abstract translation: 在无线通信系统中提供用于上行链路MIMO传输的方法和装置。 在一些特定方面，用于选择用于上行链路MIMO传输的传输格式组合的E-TFC选择过程可以在UE被强制或缓冲限制的情况下采取某些步骤。 例如，在等级2传输中，非调度数据仅分配给主流。 如果分配的非调度数据小于所确定的主流传输块大小，则将调度的数据以不超过确定的主流TBS的量分配给主流。 最后，以不超过所确定的二级流TBS的量将分配的数据分配给次流。

Abstract: In a wireless access network, a false base station (FBS) may imitate a legitimate base station by repeating the transmissions of the legitimate base station at a higher power level such that one or more user equipment (UEs) synchronize with the FBS instead of the legitimate base station. The present disclosure provides a UE that detects an FBS. The UE may estimate a time of arrival of different multipath components of a downlink signal corresponding to a physical cell identity. The UE may determine an existence of FBS based on a difference between the times of arrival of two of the different multipath components exceeding a threshold amount of time. The UE may perform a mitigation operation in response to determining the existence of the FBS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a master node (MN) may receive a message indicating that a user equipment (UE) has determined that a condition for a conditional primary secondary cell (PSCell) change has been satisfied for a candidate target PSCell. The candidate target PSCell may be one of a set of candidate target PSCells associated with the UE in a conditional PSCell change configuration provided by a base station. The MN may transmit, to a source secondary node, a confirmation message associated with the conditional PSCell change. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive time sensitive communication assistance information (TSCAI), associated with extended reality data traffic, that comprises at least one of multimedia cadence information, timing update information, timing offset information, configurable parameter set information, or extended reality specific traffic pattern information. The network node may transmit feedback associated with the TSCAI. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. Private keys may be maintained upstream in a network at a more secure location. For example, when a signature is needed, a base station may transmit a signing request to a signing function within the core network and may transmit system information (SI) to be protected. The signing function may use a private key to generate a signature for the SI and returns the signature to the base station. The base station may transmit the SI and the signature to user equipment (UEs) within a coverage area of the base station. The UEs may obtain a public key corresponding to the private key and may use the public key to verify that the signature for the SI is valid and from the base station. The public key, and hence the signature, may correspond to a particular tracking area.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that the UE has received, from a network, a sufficient quantity of protocol data units (PDUs) to decode a frame. Accordingly, the UE may indicate, to the network, that the UE has decoded the frame. Similarly, the UE may determine that the network has received, from the UE, a sufficient quantity of PDUs to decode a frame. Accordingly, the UE may refrain from transmitting one or more additional PDUs associated with the frame. Additionally, or alternatively, the UE may receive, from the network, an indication to disable some feedback to the network. Accordingly, the UE may refrain from transmitting one or more feedback signals based at least in part on the indication. Numerous other aspects are described.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for beam selection and codebook learning techniques based on XR perception information. A UE may receive sensor information indicative of a direction of a current serving beam relative to the UE. The UE may be configured to communicate with a base station based on a BPL associated with the direction of the current serving beam. The UE may perform a measurement for the base station and the UE to communicate over the BPL based on the sensor information indicating that the direction of the current serving beam relative to the UE is different from a previous serving beam direction relative to the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A UE may receive outer coded downlink signaling via carrier aggregation, and may deactivate retransmission protocols and then selecting at least one of two different feedback modes. A first feedback mode may include a radio link control (RLC) status report mode (e.g., which may be referred to as mode 1, or RLC mode 1). A second feedback mode is a hybrid automatic repeat request (HARQ) feedback mode (e.g., which may be referred to as mode 2, or HARQ mode 2. The network may configure the UE with parameters for operating in mode 1, mode 2, or both, or the UE may select a feedback mode autonomously. The UE may refrain from transmitting additional feedback signaling, and retransmissions may be deactivated, resulting in improved power savings and more efficient use of system resources.

Abstract: Some wireless communications systems may support logical channel prioritization (LCP) adaptation. A user equipment (UE) may receive signaling scheduling multiple data flows associated with a set of channels in particular logical channels, where each data flow of the multiple data flows is associated with a set of one or more parameters. The UE may calculate a deadline metric (DM) associated with a transmission time of each data flow based on the sets of one or more channel prioritization parameters and may adapt the set of one or more parameters associated one or more data flows of the multiple data flows based at least in part on the DM. The UE may transmit a first data flow of the multiple data flows based at least in part on a prioritization of the first data flow over a second data flow, the prioritization based at least in part on the adapting.
