Abstract:
Different types of backhauls are used to provide connectivity for an access point. In some implementations, an access point monitors conditions on at least one backhaul to determine whether each backhaul is capable of supporting any QoS requirements of the access point's traffic flows. If the access point determines that a backhaul is capable of supporting the QoS requirement of a given traffic flow, the access point may configure the traffic flow to be routed via that backhaul. In some implementations, an access point selects a different backhaul for a traffic flow based on the type of traffic flow. For example, upon determining that a traffic flow is destined for an entity associated with another backhaul, the access point may switch to the other backhaul for routing that traffic flow.
Abstract:
Transmit power management for small cells in a wireless communication environment may be achieved by receiving information generated by a plurality of access terminals associated with an access point, categorizing the access terminals based on the received information, and determining transmit power for the access point based on the categorization of the access terminals.
Abstract:
Coexistence solutions may be needed for sharing channels with multiple operators. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus for sharing channels with multiple operators are provided. The apparatus may detect a conflict between a first base station and a second base station based on a coverage overlap between the first base station and the second base station. The apparatus may resolve the conflict based on a classification of the conflict, and at least one of a channel priority or a channel preference.
Abstract:
A base station includes a base unit and a plurality of remote antenna units (RAUs). Each of the RAUs includes a physical layer circuit (PHY). The PHYs are configured to each use the same physical layer identifier, but each PHY includes its own hardware for supporting users in the coverage area of that PHY. The base unit controls resource allocation for the RAUs to increase the capacity of the base station and/or reduce interference between PHYs.
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:
Methods and apparatus for communication comprise adjusting a transmission power value of one or both of a network entity and a proximate network entity from a first transmission power value to a second transmission power value based at least in part on one or both of a load level value of the network entity and a load level value of the proximate network entity to offload at least one user equipment (UE) to the proximate network entity, wherein the network entity serves the at least one UE. Further, the methods and apparatus comprise updating a power/resource management policy at the network entity based on adjusting the transmission power value of one or both of the network entity and the proximate network entity.
Abstract:
The assignment of physical layer identifiers for access points is coordinated with the assignment of transmit powers for the access points. For example, only those access points that transmit at a relatively high power level are allowed to use a physical layer identifier from a subset of physical layer identifiers allocated for mobility measurements. Any other access points will use a physical layer identifier that is not allocated for mobility measurements. By restricting the number of access points that are allowed to use a physical layer identifier allocated for mobility measurements, confusion and collision in the network may be mitigated.
Abstract:
Various aspects and features related to wireless communication for high reliability and low latency are described. In an aspect of the disclosure, a method, a computer-readable medium, a system, and an apparatus are provided. A method of wireless communication includes communicating with a network via one or more network nodes using separate wireless links for each UE in a set of UEs using a same RAT. The method includes either transmitting uplink data traffic from a common source to the network nodes using respective separate wireless links corresponding to the two or more UEs or receiving downlink data traffic destined for the common source from the network nodes using respective separate wireless links corresponding to the two or more UE.
Abstract:
The present disclosure generally relates to techniques to increase reliability of communications within a network during a low reliability period. The network may include a user equipment (UE) communicatively coupled with one or more transmit/receive points (TRPs), with the communications between the UE and the one more TRPs requiring a reliability above a first reliability threshold. A processor of a network entity may identify a low reliability period which occurs when the reliability of the communications is determined to be below a second reliability threshold. The processor may cause the network to perform one or more remedial actions to increase the reliability during the low reliability period.
Abstract:
The disclosure is related to small cell base station power management within a wireless network. In an aspect, at least one metric related to operational and non-operational states of the small cell base station is determined, a reliability state of the small cell base station is determined based on the at least one metric related to the operational and non-operational states of the small cell base station, and one or more operational parameters of the small cell base station are adjusted based on the determined reliability state.
