Abstract: Techniques for performing network-assisted peer discovery to enable peer-to-peer (P2P) communication are described. In one design, a device registers with a network entity (e.g., a directory agent) so that the presence of the device and possibly other information about the device can be made known to the network entity. The network entity collects similar information from other devices. The device sends a request to the network entity, e.g., during or after registration. The request includes information used to match the device with other devices, e.g., information about service(s) provided by the device and/or service(s) requested by the device. The directory agent matches requests received from all devices, determines a match between the device and at least one other device, and sends a notification to perform peer discovery. The device performs peer discovery in response to receiving the notification from the network entity.

Abstract: Wireless communication devices, such as a scheduled entity, are adapted to facilitate uplink transmissions on multiple physical uplink control channels (PUCCHs) of a regular burst period. According to one example, a scheduled entity may obtain a payload for an uplink transmission on a PUCCH. The scheduled entity may subsequently send the uplink transmission utilizing two or more physical uplink control channels (PUCCH) of a regular burst period, where each PUCCH is associated with a different frequency band of the regular burst period. According to one example, a scheduling entity may receive an uplink transmission, where the uplink transmission utilizes a first PUCCH of a regular burst period, and at least a second PUCCH of the regular burst period, each of the first and second PUCCHs being associated with respectively different frequency bands of the regular burst period. Other aspects, embodiments, and features are also included.

Abstract: Methods, systems, and devices for wireless communications are described. In some cases, randomized shifts of a base sequence may be used for transmitting uplink control information. For example, a user equipment (UE) may identify a base sequence of an uplink control message. The UE may also receive signaling that indicates a UE-specific initial shift that may be applied to the base sequence. In some examples, the signaling that indicates the randomized shift may be explicit, implicit, or a combination thereof. After determining one or more shifted sequences based on the UE-specific initial shift, a payload of the uplink control message, and the base sequence, the UE may select a shifted sequence to be transmitted, where the selection is based on a payload of the uplink control message. For example, different shifted sequences may be selected for respective transmissions of scheduling requests, 1-bit acknowledgments (ACKs), 2-bit ACKs, and the like.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications and more specifically to transmission resource management for ordered physical random access channel (PRACH) signals. An example method performed by a base station generally includes providing an indication of a set of transmission resources, within a narrowband region of a wider system bandwidth, for transmitting scheduled physical random access channel (PRACH) signals by a first user equipment (UE) and transmitting a command to the first UE to transmit a scheduled PRACH.

Abstract: Narrowband communications in a wireless communications system may include a common synchronization signal, such as a primary synchronization signal (PSS), secondary synchronization signal (SSS), or physical broadcast channel (PBCH). Content of the common synchronization signal may indicate a location of narrowband data transmissions in a narrowband region of a system bandwidth. The location of the narrowband region may be in-band within one or more wideband transmissions, within a guard-band bandwidth adjacent to the wideband transmissions bandwidth, or within a stand-alone bandwidth that is non-adjacent to the wideband transmissions. The common synchronization signal may be located within a predefined search frequency and may include an anchor synchronization channel present in certain resources of allocated narrowband communications resources. Narrowband data region resources may be distributed in other portions of the narrowband communications resources, and may be allocated to different users to provide transmit diversity.

Abstract: Methods, systems, and devices for wireless communication are described that support discontinuous scheduling. A base station may transmit, to a user equipment (UE), a grant of resources of a communication channel over a multiple of aggregated TTIs. The UE may monitor a control channel for the grant of resources transmitted by base station. The base station and the UE may identify a location of an excluded TTI within the plurality of aggregated TTIs. The excluded TTI may correspond to a TTI for communicating synchronization signals, random access channel (RACH) signals, or the like. The base station may communicate with the UE via the resources of the communication channel over at least a subset of the aggregated TTIs based on the grant and the location of the excluded TTI.

Abstract: Signaling strategies for an advanced receiver with interference cancellation (IC) and suppression is discussed. Upon enablement of an advanced interference cancellation procedure according to the disclosure, transmitters within the enabled area transmit according to transmission restriction configurations that provide transmission limits based on either frequency, time, or scheduling. The restrictions on the transmitters reduces the complexity of processing by neighboring advanced receivers for cancellation of interference from the restricted transmitters. At the advanced receiver, transmission information, such as scheduling, reference signal (RS), resource block (RB) allocation, and the like, may either be determined through blind detection or received directly through signaling. The advanced receiver may use this transmission information associated with each interfering signal to detect, decode, and subtract the interfering signals from the received transmissions.

In an aspect, a scheduled entity obtains a resource allocation for transmitting different types of uplink control information (UCI), wherein the resource allocation is based on a combination of the different types of UCI and transmits the different types of UCI based on the obtained resource allocation. Other aspects, embodiments, and features are also claimed and described.

Abstract: Wireless communication devices are adapted to facilitate a random access procedure. According to one example, scheduled entity can transmit a first transmission that is received by a scheduling entity. The first transmission may include a physical random access channel (PRACH) preamble sequence and a first message including information for determining a device-specific network identifier for the scheduled entity. The scheduling entity may transmit a second transmission that is received by the scheduled entity. The second transmission may include information on a physical downlink control channel (PDCCH) addressed to the device-specific network identifier for the scheduled entity, and a second message on a physical downlink shared channel (PDSCH). Other aspects, embodiments, and features are also included.

Abstract: The present disclosure generally relates to methods, and apparatus for implementing the methods, for using sequence based uplink control information in 5G New Radio wireless communications. The method may include a user equipment (UE) may construct a signal based at least on resource assignment information received from a base station. The resource assignment information received by the UE may indicate frequency resources, a base sequence index, and a shift index. In a non-limiting example, the resource assignment information may include frequency resource assignment information related to one or more clusters. In implementations in which the frequency resource information includes a plurality of clusters, each of the plurality of clusters use a different base sequence and may use the same or different cyclic shifts. These sequences may be multiplexed in a non-orthogonal manner. The UE may use the resource assignment information to transmit the constructed signal to the base station.
