The present disclosure provides self-decodable redundancy versions for a systematic code. An apparatus for wireless communications includes at least one processor coupled with a memory and comprising encoder circuitry configured to encode a set of information bits using a systematic code to generate an encoded bit stream with information bits and parity bits, and bit ordering circuitry configured to re-order bits in the encoded bit stream to distribute the information bits and the parity bits. The apparatus includes a transmitter configured to transmit the re-ordered bits in accordance with a radio technology via one or more antenna elements situated proximate the receiver.

Communication techniques with self-decodable redundancy versions (RVs) using systematic codes

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration message configuring the UE to communicate coordinated transmissions with multiple transmission reception points (TRPs) using a first coordinated transmission mode of a set of different coordinated transmission modes. The UE may receive, based on the configuration message, downlink control information including at least one indicator and receive a first coordinated transmission communicated in accordance with the first coordinated transmission mode. The UE may transmit, in accordance with a feedback configuration corresponding to the at least one indicator and the first coordinated transmission mode, a feedback message for the first coordinated transmission to at least one of the multiple TRPs.

Feedback design for multi-transmission reception point transmission

Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently transmitting data and control information in a first RACH message to a base station as part of a two-step RACH procedure. In particular, rather than or in addition to transmitting data and control information in a physical uplink shared channel (PUSCH) in the first RACH message, a user equipment (UE) may transmit the data and control information along with a RACH preamble in a RACH occasion in the first RACH message (e.g., when the number of bytes of data or control information to be transmitted is low). Using these techniques, in some instances, the UE may transmit the data and control information in a first RACH message without transmitting the PUSCH, and the overhead associated with transmitting the PUSCH may be eliminated.

Random access channel occasion configuration

Certain aspects of the present disclosure provide methods, apparatus, and systems for predicting a location of a device in a spatial environment using a machine learning model. An example method generally includes measuring a plurality of signals received from a network entity at a device. A channel state information (CSI) measurement is generated from the measured plurality of signals. Generally, the CSI measurement includes a multipath component. Positions of one or more anchors in a spatial environment are identified based on a machine learning model trained to identify the positions of the one or more anchors based on the CSI measurement. A location of the device is estimated based on the identified positions of the one or more anchors.

Unsupervised location estimation and mapping based on multipath measurements

Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for determining a suitable pattern for transmitting reference signals used for positioning on allocated resources. In particular, the pattern may be used to assign the reference signals to frequency tones across multiple symbols such that the frequency tones to which the reference signals are mapped in at least two consecutive symbols are non-adjacent (e.g., separated by at least one frequency tone). In some cases, a wireless device may determine the pattern used to assign reference signals used for positioning autonomously (e.g., based on configured algorithms or a look-up table), and, in other cases, a wireless device (e.g., a user equipment (UE)) may determine the pattern used to assign reference signals used for positioning based on a configuration received from another wireless device (e.g., a base station).

Patterns for reference signals used for positioning in a wireless communications system

Certain aspects of the present disclosure provide techniques for slot aggregation in new radio (NR) systems. A method of wireless communication by a user equipment (UE) includes receiving radio resource control (RRC) signaling providing a semi-static configuration for transmission and/or reception of a repeated transport block (TB) and/or a different TB in each of a plurality of aggregated slots. The UE transmits or receives the TBs in the plurality of aggregated slots based on the semi-static configuration. Another method is provided in which the UE transmits and/or receives a demodulation reference signal (DMRS) in each of a plurality of aggregated slots, each DMRS associated with a repeated TB or a different TB in the slot. The UE determines, based on received signaling, whether the DMRS use a same precoder or a different precoder and modulates and/or demodulates the TBs in the plurality of aggregated slots based on the determination.

Signaling for slot aggregation

Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may send a capabilities report to a base station. The capabilities report may include an explicit indication that the UE is capable of receiving a maximum layer radio resource control (RRC) parameter, or may include ambiguous (e.g., multiple) capabilities. The base station may receive the capabilities report, and may determine whether to transmit a maximum layer RRC parameter based on the explicit indication, or the ambiguous capabilities, which indicates a maximum number of layers to be used for subsequent communications. If the UE is capable of receiving the maximum layer RRC parameter, the base station may send the maximum layer RRC parameter to the UE, and may perform wireless communications according to the indicated maximum number of layers.

Configuring a maximum number of layers

Certain aspects of the present disclosure provide techniques for selecting an antenna configuration for transmitting in a wireless communication network. An example technique may include determining that a front guard period is not scheduled between a scheduled uplink transmission and a scheduled sounding reference signal (SRS) transmission, and based on the determination, transmitting the scheduled SRS transmission using a first antenna configuration after transmitting the scheduled uplink transmission using the first antenna configuration.

Guard period optimization for multi-antenna user equipments

Techniques are described for wireless communication. A method for wireless communication at a user equipment (UE) includes identifying, while the UE is in a connected mode with a network, a radio resource configuration of the UE, selecting a dedicated set of resources for the UE or a common set of resources for a plurality of UEs based at least in part on the identified radio resource configuration, and transmitting a pilot signal to the network using the selected set of resources. Methods for wireless communication at a network access device and a network access device controller are also described.

Techniques for providing uplink-based mobility

Bandwidth part (BWP) switching may benefit a wireless communications system. Such BWP switching may include indication of one or more timing parameters used for time domain resource allocation. For example, the timing parameters may be indicated based on an index to a look-up table (e.g., a bit field in a control transmission). In some cases, one or more tables may be configured for a given BWP, and different tables may contain a different number of rows. The size of the bit field indexing the table may in turn depend on the number of rows. When switching from a first BWP to a second BWP, the size of the bit field may be based on the table of the first BWP, but the bit field may index the table of the second BWP. Techniques supporting improved timing parameter management during BWP switching are discussed herein.

Timing parameter management for bandwidth part switching

Certain aspects of the present disclosure provide techniques for reporting channel state information (CSI) with spatial and time domain compression.

Channel state information (CSI) with spatial and time domain compression

Certain aspects of the present disclosure provide techniques for remote interference mitigation between base stations using reference signals. Certain aspects provide a method for wireless communication by a first base station (BS). The method includes receiving a reference signal (RS) from a second BS. The method further includes performing interference measurement corresponding to interference from the second BS based on the RS being associated with the second BS.

Reference signal for remote interference management

Wireless communications systems and methods related to downlink (DL) control channel communications are provided. A wireless communication device identifies a search space set including a plurality of PDCCH candidate search spaces for a downlink control channel. The wireless communication device determines that a first resource associated with a first PDCCH candidate search space of the plurality of PDCCH candidate search spaces overlaps with a preconfigured resource. The wireless communication device monitors for a downlink control message over the downlink control channel by excluding monitoring in at least the first PDCCH candidate search space based on the determining.

Physical downlink control channel (PDCCH) monitoring with overlapping resources

Methods, systems, and devices for wireless communication are described. Techniques to use capability information for user equipment in wide band systems such as millimeter wave systems. The capability information can include information indicative of support for limited non-contiguous intra-band carrier aggregation. The capability information can include information indicative of support for sharing time and frequency tracking information between cells.

Carrier aggregation capability signaling

Aspects described herein relate to configuring and selecting preamble and payload occasions for performing two-step random access procedures. Configurations on preamble occasions, payload occasions, association pattern between the occasions and synchronization signal block (SSB) beams, and the rules for selecting preamble and payload occasions for random access message transmission can be determined by the network and signaled to user equipment (UE). Based on the configurations and rules, UE can measure the link level quality and select possible preamble and payload occasions for one or more SSB beams achieving a threshold signal quality. Sets of one or more preamble occasions and one or more payload occasions can be further determined based on whether the preamble and payload occasion(s) can achieve a threshold transmission latency. The one or more preamble occasions and one or more payload occasions can be used to transmit random access messages in the two-step random access procedure.
