Abstract: Techniques and apparatus for transmitting control information to maintain hybrid automatic repeat request (HARQ) processes for multiple carriers in different frequency ranges, such as frequency range 1 (FR1) and frequency range 2 (FR2), in carrier aggregation scenarios are described. A first numerology of a first component carrier (CC) in FR1 and a second numerology of a second CC in FR2 are determined. A HARQ configuration that includes an indication of a set of physical uplink control channel (PUCCH) resources is determined. A number of symbols of the set of PUCCH resources is based on the first numerology and the second numerology. The HARQ configuration is transmitted to a user equipment (UE). HARQ feedback is transmitted on the first CC for data received on the second CC, using the set of PUCCH resources of the HARQ configuration.

Abstract: Aspects of the present disclosure disclose techniques for the indication of the allocation of the downlink (DL) demodulation reference signal (DM-RS) ports for the data channel in NR communications. In some examples, the channel state information (CSI) reference signal (CSI-RS) may be associated with a corresponding DM-RS for a DL data channel. The transmitting device, in some examples, may further transmit a notification that provides resource allocations (e.g., port allocations) that minimize the redundant information that is required to be transmitted from the base station to the user equipment (UE) when the DM-RS port allocation is the same as the CSI-RS port allocation received by the UE in an earlier time slot.

Abstract: Disclosed are methods and apparatuses for resolving aliasing ambiguities produced when using channel state information reference signal, a sounding reference signal (SRS) or other transmission as a positioning reference signal (PRS) occupying a subset of tones of a PRS bandwidth. The aliasing ambiguity results in a plurality of different possible positioning measurements, such as time of arrival (TOA), reference signal timing difference (RSTD), or reception to transmission difference (Rx−Tx). The aliasing ambiguity may be resolved using a previous position estimate that may be used to produce an approximation of the expected positioning measurement. A position estimate may be generated using a multiple stage PRS configuration, in which one or more stages provide a coarse position estimate that has no ambiguity, which can be used to resolve the ambiguity of a more accurate position estimate resulting from the PRS signal.

Abstract: Aspects described herein relate to determining a failure associated with reception, by a base station, of an initial transmission of a random access message transmitted by the UE in a two-step random access procedure, and based on determining the failure situations associated with reception of the random access message, configuring the parameters of a retransmission and/or retransmitting at least a portion of the random access message.

Abstract: This disclosure provides systems, methods and apparatus for determining a target base station timing advance value between a user equipment (UE) and target base station in connection with a random access channel (RACH)-less handover procedure. In one aspect, the UE may determine the target base station's timing advance based at least in part on a timing difference between the target base station and the source base station and based at least in part on a timing offset associated with an uplink and a downlink of the UE. In some aspects, the target base station may determine the timing advance using an uplink reference signal of the UE. In some aspects, the UE may report a timing difference between the target base station and the source base station, and the source cell may determine a timing advance based at least in part on the timing difference.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment or a base station may determine that a condition for entering a reduced monitoring state is satisfied, wherein the reduced monitoring state uses at least one of: a diminished radio frequency chain configuration, a diminished channel monitoring configuration, a restriction on receiving or transmitting a shared channel or a control channel, or a combination thereof; and communicate using the reduced monitoring state. Numerous other aspects are provided.

Abstract: A user equipment (UE) may be configured to receive configuration information from a base station, and the configuration information may indicate at least two different random access channel (RACH) request configuration parameters that each is associated with a respective radio resource control (RRC) state. The UE may be further configured to generate a first message associated with a two-step RACH procedure including a preamble and a payload, the payload including data on an uplink data channel and at least one reference signal. The UE may be further configured to transmit the first message to the base station using at least one of the at least two different RACH request configuration parameters that corresponds to an RRC state of the UE. The preamble may be transmitted on a first set of resources associated with a RACH occasion, and the payload may be transmitted on a second set of resources.

Abstract: Disclosed are techniques for determining a line-of-sight (LOS) path between a transmitter and a wireless device. In an aspect, a wireless device receives a first reference signal on a first frequency band at a first time, receives a second reference signal on a second frequency band at a second time, compares the first time to the second time, and determines, at least based on the comparison of the first time to the second time, which of the first reference signal and/or the second reference signal followed the LOS path between the transmitter and the wireless device.

Abstract: Methods and apparatuses for wireless communication are provided. A transmitting apparatus receives an indication to use multiple subframes to send uplink control information, codes the uplink control information over the multiple subframes based on the indication, and sends the coded uplink control information via the multiple subframes. Sending the coded uplink control information includes transmitting acknowledgement information (ACK) of a current downlink-centric self-contained subframe in an uplink acknowledgement portion of the current downlink-centric self-contained subframe, bundling ACK bits of multiple downlink-centric self-contained subframes and encoding the bundled ACK bits to generate parity acknowledgement bits associated with systematic acknowledgement bits, transmitting the systematic acknowledgement bits in each uplink acknowledgement portion of the multiple downlink-centric self-contained subframes, and transmitting the parity acknowledgement bits associated with the acknowledgement information bits of the multiple downlink-centric self-contained subframes in an uplink-centric self-contained subframe that is sequentially subsequent to the multiple downlink-centric self-contained subframes.
