Abstract: Methods, systems, and devices are described for wireless communication. In one method, a method of wireless communication at a user equipment (UE) includes receiving a synchronization signal. The synchronization signal may be common to a plurality of cells within a network. The method further includes acquiring a timing of the network based on the synchronization signal, and transmitting a pilot signal in response to acquiring the timing of the network. The pilot signal may identify the UE and be concurrently receivable by the plurality of cells within the network. Other aspects, features, and embodiments are also claimed and described.

Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications systems support mobile broadband (MBB) communications and low latency communications. To accommodate low latency communications, a base station may identify resources allocated for MBB communications, and the base station may reassign (or puncture) these resources for low latency communications. The base station may transmit an indication of the reassigned (or punctured) resources to one or more user equipment (UEs). The base station may transmit an indication of the reassigned resources in a transmission time interval (TTI) that is subsequent to a TTI reassigned (or punctured) for low latency communications (e.g., a post indication). The base station may transmit the post indication in a retransmission grant of a physical downlink control channel (PDCCH) or in downlink control information (DCI) of a PDCCH.

Abstract: Some wireless communication systems may attempt to balance frequent transmission opportunities (e.g., where the frequency of the opportunities may refer to gaps in the time domain, frequency domain, etc.) with a desire for communication reliability and/or interference diversity. In accordance with the described techniques, some such systems may apportion communicating devices into groups, where resources are strategically assigned to each group so as to reduce latency without significantly compromising communication reliability or interference diversity (e.g., by allowing a membership of the groups to cycle through all possible combinations before repeating). Such techniques may support delay-sensitive communications, channel sounding procedures, or other similar types of transmissions. Resources may be allocated based on a scheduling parameter transmitted to a user equipment (UE), which may implicitly or explicitly indicate a plurality of resource offsets to the UE.

Abstract: Aspects of the present disclosure provide various apparatuses and methods for retransmitting code blocks (CBs) and code block group (CBG) definitions that can improve CBG-based data retransmission efficiency. When an interference pattern is bursty and does not align with CBG or symbol boundary, the disclosed CBG definitions can reduce or avoid retransmission of successfully received CBs along with the CBs that need to be retransmitted.

Abstract: Methods, systems, and devices for wireless communication are described. In some examples, a wireless device (e.g., a user equipment (UE) or a base station) may encode a codeword from a set of information bits using an LDPC code. The wireless device may then transmit multiple versions of the codeword to improve the chances of the codeword being received. In some aspects, the wireless device may use the techniques herein to generate self-decodable redundancy versions of the codeword to be transmitted to the receiving device. Accordingly, a receiving device may be able to identify information bits from one or more redundancy versions of the codeword even if the receiving device failed to receive an original transmission of the codeword.

Abstract: The present disclosure provides for adaptive resource management in new radio operations that adapts a numerology including a subcarrier spacing and/or cyclic prefix for a user equipment (UE) traveling at a high speed. A base station may transmit via a plurality of remote radio heads (RRH) to a user equipment (UE) is moving along a high speed track. The base station may transmit, in a first time period, using a first numerology including a first subcarrier spacing and a first cyclic prefix ratio, a first transmission for the UE. The base station may transmit, in a subsequent time period, using a second numerology including a second subcarrier spacing and a second cyclic prefix ratio, a second transmission for the UE. At least one of the second subcarrier spacing is different than the first subcarrier spacing or the second cyclic prefix ratio is different than the first cyclic prefix ratio.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment may be configured to monitor a first set of decoding candidates within a first search space for receiving a physical downlink control channel message. A base station may identify downlink data for the user equipment and may transmit a signal to the user equipment. The user equipment may receive the signal within the first search space. In some cases, the signal may include a command for activating a second search space. The user equipment may monitor a second set of decoding candidates within the second search space based on receiving the signal. The user equipment communicate, with the base station, based on monitoring the first set of decoding candidates within the first search space and the second set of decoding candidates within the second search space.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may report a phase-noise compensation reference signal (PCRS) configuration to a base station to enable per-UE PCRS signaling. For example, a UE may operate in a wireless communications system using carrier frequencies greater than 6 GHz, which may be affected by phase noise. The UE may accordingly determine a PCRS configuration based on a capability to receive signals. The PCRS configuration may include a resource mapping for one or more PCRS, a number of PCRS ports used for PCRS, a multiplexing scheme for one or more PCRS ports, or the UE's phase noise estimation capability. The UE may then transmit a reporting message including the PCRS configuration to a base station. The base station may use the PCRS configuration for PCRS transmissions to the UE.

Abstract: Methods, systems, and devices for wireless communications are described which may enable a user equipment (UE) and a base station to use outer-loop feedback support to reach a desired error rate for low latency communications. For example, a base station may transmit a proxy acknowledgement feedback configuration to a UE for communications associated with a low target error rate. In some cases, after receiving the communications from the base station, the UE may receive secondary communications from the base station. The UE may then decode the first and/or second communications according to the proxy acknowledgement feedback configuration and/or a normal acknowledgement feedback configuration and may determine a proxy acknowledgement feedback based on the decoding. Further, the UE may transmit the proxy and/or normal acknowledgement feedback to the base station, which may update outer-loop power settings for the low latency communications based on the acknowledgement feedback.
