Abstract: Certain aspects of the present disclosure provide techniques for processing multi-layer transmissions simultaneously received from multiple network entities. An example method for wireless communications by a user equipment (UE) includes obtaining a first channel matrix for spatially processing multi-layer transmissions from a first network entity received via a first antenna panel at the UE; obtaining a second channel matrix for spatially processing multi-layer transmissions from a second network entity received via a second antenna panel at the UE; and spatially processing one or more multi-layer transmissions from the first and second network entities simultaneously received via the first and second antenna panels at the UE, based on a third channel matrix including entries of the first channel matrix and entries of the second channel matrix.

Abstract: Methods related to wireless communication systems and scheduling channel state information operations and transmissions. A user equipment (UE) receives, from a base station (BS), a channel state information (CSI) computation request. The UE then identifies a first CSI measurement resource based on the CSI computation request. The UE determines CSI based on the first CSI measurement resource, and receives, from the BS, a CSI report transmission request associated with the first CSI measurement resource. The UE optionally transmits to the BS a CSI report based on the first CSI measurement resource or a different CSI measurement resource. Other features are also claimed and described.

Abstract: A user equipment (UE) includes: a transceiver configured to receive positioning signals; a memory; and a processor, communicatively coupled to the transceiver and the memory, configured to: send, via the transceiver to a network entity, a capability indication that includes a first positioning-method indication indicating that the processor supports simultaneous processing of a first combination of positioning methods; and simultaneously process one or more first positioning signals in accordance with the first combination of positioning methods to determine first position information for the UE.

Abstract: A user equipment (UE) may utilize frequency domain (FD) compression for reporting channel state information (CSI) including a precoding matrix indicator (PMI). The UE may receive a CSI configuration specifying a first set of configured FD units to be reported. The UE may determine a first number of FD units based on the first set of configured FD units. The UE may select a second number of FD units that is greater than or equal to the first number of FD units. The UE may calculate, for one or more layers, a PMI for a second set of FD units including a number of FD units equal to the second number of FD units. The UE may allocate, according to a mapping rule, a number of PMIs for the first set of FD units to a subset of the PMIs for the second set of FD units.

Abstract: In order to enable a UE receiving a narrowband signal transmitted using in-band resources to use the LTE reference signals to assist the UE in receiving the narrowband signal using an in-band deployment, a phase rotation employed by the base station may be fixed relative to a known reference position in time. An apparatus for wireless communication at a base station may determine a phase offset for a narrowband signal for transmission using wideband resources, the phase offset having a relationship to a reference point in time and transmit the narrowband signal using the determined phase offset. An apparatus for wireless communication at a UE may receive a narrowband signal having a frequency location within a wideband signal and rotate a symbol of the wideband signal by a per symbol phase offset having a relationship of the phase offset to a reference point in time.
