PACKAGE SUBSTRATES EMPLOYING PAD METALLIZATION LAYER FOR INCREASED SIGNAL ROUTING CAPACITY, AND RELATED INTEGRATED CIRCUIT (IC) PACKAGES AND FABRICATION METHODS (17656477)

Abstract

Package substrates employing a pad metallization layer for increased signal routing capacity, and related integrated circuit (IC) packages and fabrication methods. To support increased signal routing density in an IC package while mitigating an increase in overall IC package thickness, an outer metallization layer of the package substrate is provided as a thinner, pad metallization layer. A metal layer in the pad metallization layer includes metal pads for forming external connections to the package substrate. This allows an area in the adjacent metallization layer that would otherwise have larger width metal pads for forming external interconnects, to be used for other signal routing within the package substrate. This can increase the overall signal routing density of the package substrate while mitigating the increase in overall package substrate thickness if a full-sized additional metallization layer were added to the package substrate.

A first TRP may transmit a control signal to the UE indicating resources for receiving a medium access control element (MAC-CE), where the control signal includes an indication that associates the MAC-CE with the first TRP. The first TRP may transmit the MAC-CE to the UE which may include a beam update indication for the first TRP. The UE may transmit an acknowledgement to the first TRP based on receiving the MAC-CE. The UE may also transmit an acknowledgment to the second TRP indicating that it has received a beam update indication from the first TRP. In some cases, the first TRP may send a MAC-CE signal to the UE including beam update information for the second TRP.

TRANSMISSION CONFIGURATION INDICATOR STATE DETERMINATION BASED ON MULTIPLE CONTROL CHANNEL REPETITIONS (17665474)

Abstract

Methods, systems, and devices for wireless communications are described in which network nodes may configure linked search space (SS) sets that provide multiple instances of control channel communications. A beam configuration, or transmission configuration indicator (TCI) state, for a downlink transmission scheduled by instances of the control channel communications may be determined based on a control resource set (CORESET) of one or more of the different SS sets. A first network node may decode a first control channel communication from one or more instances of the control channel communications, the first control channel communication indicating a resource allocation for a first downlink communication. The first network node may determine whether one or more TCI states are applied to the first downlink communication based on one or more CORESETs associated with the first control channel communication, and receive the first downlink communication based on the determined one or more TCI states.

USER EQUIPMENT INDICATION OF CODE BLOCK MAPPING TYPE PREFERENCE FOR PHYSICAL DOWNLINK SHARED CHANNEL (17656403)

Abstract

In a wireless communication system, dynamic changes of a code block (CB) to resource element (RE) mapping type may improve decoding performance in some scenarios. A user equipment may provide an indication of a preferred CB mapping type. A base station may transmit a physical downlink shared channel (PDSCH) based on a first dynamic CB mapping type in one or more slots. A UE may receive the PDSCH and determine a second CB mapping type that is preferred by the UE based on a metric. The UE may transmit an indicator of the second CB mapping type, for example, as a one-bit or two-bit indicator, which may be coupled with a channel state information (CSI) report or signaled in uplink control information (UCI) independently from a CSI report. The base station may consider the indicator when selecting a new dynamic CB mapping type for the UE.

RESOURCE BLOCK GRID ALIGNMENT AT SIDELINK NODES (17704910)

Abstract

Methods, systems, and devices for wireless communications are described to support resource block (RB) grid alignment at user equipments (UE) in sidelink communications. In a first example, communicating UEs may support different RB grids and a receiving UE may attempt multiple decoding hypotheses for receiving a sidelink control channel from a transmitting UE, where each hypothesis may correspond to a different RB grid. In a second example, an RB grid for a sidelink control channel may be common, or aligned, for a transmitting UE and a receiving UE, such that the receiving UE may receive the sidelink control channel using the common RB grid. In a third example, demodulation reference signals (DMRSs) and resource element (RE) rate matching for a sidelink control channel may be common, or aligned, for a transmitting UE and a receiving UE, such that the receiving UE may receive the control channel using the aligned DMRSs.
