Abstract: In a wireless network comprising a plurality of carriers available for carrier aggregation transmissions between a base station and UE, the base station: (i) determines whether a requirement exists to transmit data between the UE and the base station via a carrier aggregation transmission; (ii) in response to determining that the carrier aggregation transmission requirement exists, selects a primary component carrier and one or more secondary component carriers from the plurality of carriers for the carrier aggregation transmission based on one or more of each carrier's group delay, group delay variation, or insertion loss; (iii) allocates the selected primary and secondary component carriers to the carrier aggregation transmission; (iv) informs the UE of the allocation; and (v) executes the carrier aggregation transmission according to the allocation.

Abstract: A method and corresponding system to help improve handoff of a wireless communication device from a first network to a particular second network. The first network may maintain data that includes operational parameters of each of a plurality of second networks, such as networks that provide coverage in the same market area as the first wireless network. When the first network receives from a wireless communication device an indication that the device has detected coverage of a particular one of the second networks, the first network may then provide the device with the corresponding set of operational parameters for the detected second network.

Abstract: Carrier aggregation may occur in wireless networks when multiple carriers from either contiguous frequency bands or non-contiguous frequency bands are aggregated together as component carriers. Wireless computing devices (WCDs) may use these aggregated component carriers as a single, logical channel for wireless communication. Such a WCD may determine that an amount of carrier aggregation used by a wireless interface of the WCD has increased. The WCD may receive data packets from a correspondent device by way of the wireless interface, and the WCD may transmit, in response to receiving the data packets, acknowledgment packets to the correspondent device by way of the wireless interface. Possibly based on the amount of carrier aggregation increasing, the WCD may reduce an extent of the acknowledgment packets transmitted to the correspondent device.

Abstract: Disclosed is a method and system to help ensure contention-free response to a paging message. As disclosed, when a base station transmits a paging message for receipt by a UE, the base station includes in the paging message a contention-free random-access preamble useable by the UE to engage in contention-free random access in response to the paging message. The UE thus receives the paging message and responsively engages in a contention-free random access process with the base station, to establish a radio-link-layer connection between the UE and the base station.

Abstract: Disclosed is a method and system for sharing a remote radio head (RRH) between multiple cell sites. An RRH is be coupled with at least two separately located cell sites, so as to interface concurrently between one such cell site and a baseband unit and between the other such cell site and the baseband unit. Further, a baseband unit may thus also serve the multiple cell sites, by being coupled with the RRH that serves the multiple cell sites.

Abstract: Disclosed is a method and system for compensating excessive delay spread in uplink coordinated multipoint service. An uplink data-unit transmitted by a user equipment device (UE) on a first uplink air interface to a first base station (BS) using a first group of sub-carrier frequencies may be received at a time that is within an alignment-time range for simultaneously decoding uplink data-units from UEs transmitting on the first uplink. A determination is made that the uplink data-unit transmitted simultaneously by the UE on a second uplink air interface using a second group of sub-carrier frequencies will be received at a second BS at a time that is time is beyond the alignment-time range for simultaneously decoding uplink data-units from UEs transmitting on the second uplink. Decoding of the received uplink data-unit at the second BS is then delayed until a start time beyond the end of the alignment-time range.

Abstract: When an upper layer of a device is going to initiate an exchange of two or more messages with a corresponding upper layer of another device, the initiating device will provide from its upper layer to a lower layer such as a MAC layer an indication of how many messages the devices will be exchanging. In response to that indication, the lower layer of the initiating device will then cause the lower layer of the other device to forgo checking for and confirming availability of the channel for transmission of the next message of the exchange from the other device to the initiating device. Further, the lower layer of the initiating device may also responsively forgo for and confirming availability of the channel for a subsequent message of the exchange.

Abstract: A radio access network (RAN) may determine that a quality-of-service (QOS) load of a first base station exceeds a QOS load high threshold. The RAN may further determine that a set of wireless communication devices (WCDs) served by the first base station are located within a geographic area nearby a second base station. The RAN may additionally determine that the set of WCDs are responsible for at least a predefined portion of the QOS load of the first base station, and may power on the second base station. If at some point a second QOS load of the second base station falls below a QOS load low threshold, the RAN may facilitate handover of at least one of the WCDs served by the second base station from the second base station to the first base station, and may power off the second base station.

Abstract: Disclosed are methods and systems to facilitate selection of a donor base station to serve a relay node (RN). In particular, a base station system (BSS) may include a plurality of base stations each operable to serve user equipment devices (UEs) and operable to serve an RN. The RN is in turn operable to serve UEs. According to the disclosure, a controlling entity may determine both (i) a type of content communicated between the BSS and UEs served by the BSS (BSS-served content type) and (ii) a type of content communicated between the RN and UEs served by the RN (RN-served content type). Based on both the determined BSS-served content type and the determined RN-served content type, the controlling entity may select one of the plurality of base stations to serve the RN and may cause the selected base station to serve the RN.

Abstract: A system is described for providing backhaul over an Ethernet passive optical network (EPON). The backhaul may be backhaul for EV-DO and/or EV-DO Rev. A communications. The system for includes at least one cell site. At least two base transceiver stations are located at the cell site. The base transceiver stations receive radio signals from respective mobile stations. A first one of the base transceiver stations provides a first backhaul signal, and a second one of the base transceiver stations provides a second backhaul signal. The cell site multiplexes these backhaul signals together onto an Ethernet passive optical network. In one embodiment, these signals are provided on different pseudowire connections within a single wavelength lambda on the passive optical network. In another embodiment, the signals are provided on different lambdas of the network.
