Abstract:
Various aspects of the present disclosure generally relate to wireless communication. A user equipment (UE) may configure a first initial set of maximum transmit powers for a first subscriber module. The UE may configure a second initial set of maximum transmit powers for a second subscriber module. The UE may configure a first maximum transmit power associated with a first connection for the first subscriber module. The UE may configure, independently of the configuration of the first maximum transmit power, a second maximum transmit power associated with the second connection. The UE may transmit based at least in part on at least one of the first maximum transmit power or the second maximum transmit power. Numerous other aspects are described.
Abstract:
In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a user equipment (UE). The apparatus may transmit a supported configuration of the UE for at least one of SRS transmission or CSI-RS reception for communication with a plurality of TRPs. The apparatus may receive, in response to transmitting the supported configuration, configuration information for at least one of the SRS transmission or the CSI-RS reception, wherein the configuration information is generated based on the supported configuration. The apparatus may communicate, with at least a subset of the plurality of TRPs, using at least one of the SRS transmission or the CSI-RS reception on resource elements assigned based on the configuration information. A base station connected to the TRPs may use the SRS/CSI-RS for cluster management and scheduling or to estimate downlink channels to determine precoding for downlink transmissions.
Abstract:
Certain aspects of the present disclosure provide techniques for user equipment (UE)-centric clustering and efficient scheduling for coordinated multipoint (CoMP). A method for UE-centric clustering and central scheduling includes determining a UE conflict graph. Vertices in the UE conflict graph are UEs for which there is a transmission and edges between vertices are UEs that have a scheduling conflict. The method includes transmitting signaling to schedule the UEs with resources for the transmission based on the UE conflict graph. A method for UE-centric clustering and cluster scheduling includes determining a cluster graph. Vertices in the cluster graph are CoMP clusters for one or more UEs for which there is a transmission and edges between vertices are CoMP clusters that have a scheduling conflict. The method includes transmitting signaling to assign resources to the CoMP clusters based on the cluster graph.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may transmit a first transmission using a first resource, and transmit a retransmission of the first transmission using a second resource, wherein the second resource is configured from a plurality of second resources based at least in part on an interference muting configuration of the wireless communication device. Numerous other aspects are provided.
Abstract:
Techniques for mobility-aware contention procedures on a shared communication medium are disclosed. A connection failure associated with mobility between a source access point and a target access point sharing a communication medium may be detected. Based on the detected connection failure, a backoff threshold associated with contention-based access to the communication medium may be adapted. Contention for access to the communication medium may then proceed in accordance with the adapted backoff threshold.
Abstract:
The present disclosure presents a method and an apparatus for cell discovery in a wireless network. For example, the method may include identifying at a third cell that a first cell is a neighbor of a second cell, wherein the third cell and the second cell are neighbors, and wherein the identifying is based at least on a user equipment (UE) history information information element (IE) of a UE and performing an action at the third cell based at least on information acquired from the identification. As such, a cell may be discovered in a wireless network.
Abstract:
A small base node such as a Home Base Node (HNB), or femto cell, may reduce its transmit power in order to prevent co-channel or adjacent channel interference, or to limit its coverage area. Once the power is set, the HNB signal to a served Home User Equipment (HUE) its transmit Common Pilot Channel (CPICH) transmit power for accurate path loss estimation. When this power is outside of the permissible range, the HNB adjusts other parameters (such as Random Access Channel (RACH) constant value) to compensate for the error in signaled CPICH power, and thus compensate in that process the error in determining path loss. Similarly, if the uplink sensitivity is adjusted, to prevent interference, parameters would also be adjusted and signaled to the HUE to reflect the link imbalance.
Abstract:
The present disclosure presents a method and an apparatus for optimizing coverage area of a small cell. For example, the disclosure presents a method for estimating an available backhaul capacity of a small cell and determining a target OTA data rate for the small cell based at least on the estimated available backhaul capacity, and changing a coverage area of the small cell based at least on the determined target OTA data rate by. As such, optimizing coverage area of a small cell may be achieved.
Abstract:
A method, an apparatus, and a computer program product for wireless communication are provided in connection with determining whether to offload a device from a femto node. In one example, a serving femto node is equipped to obtain load information regarding a target node, compare an expected throughput at the target node, estimated based in part on the load information, to a threshold, and determine whether to handover a device to the target node based in part on the comparing. In an aspect, the serving node is further equipped to compute its own throughput based on parameters specific to the serving femto node or the device, and the threshold is the throughput at the serving femto node.

Certain aspects of the present disclosure provide techniques and apparatus for a mobile satellite communications application that is aware of radio frequency (RF) exposure. An example method of wireless communication by a wireless device includes determining an RF exposure budget for one or more future transmissions in compliance with an RF exposure limit. The method further includes obtaining a size of a payload for a potential transmission. The method further includes determining transmission information based at least in part on the RF exposure budget and the size of the payload. The method further includes outputting the transmission information for a user of the wireless device.
