摘要:
Systems, devices, and configurations to implement trusted connections within wireless networks and associated devices and systems are generally disclosed herein. In some examples, a wireless local area network (WLAN) may be attached to a 3GPP evolved packet core (EPC) as a trusted access network, without use of an evolved packet data gateway (ePDG) and overhead from related tunneling and encryption. Information to create the trusted attachment between a mobile device and a WLAN may be exchanged using Access Network Query Protocol (ANQP) extensions defined by IEEE standard 802.11 u-2011, or using other protocols or standards such as DHCP or EAP. A trusted WLAN container with defined data structure fields may be transferred in the ANQP elements to exchange information used in the establishment and operation of the trusted attachment.

摘要:
An evolved Node B (eNB) in a 3GPP LTE-based network receives Channel State Information-Reference Signal (CSI-RS) from a User Equipment (UE) that is configured with Precoder Matrix Indictor (PMI) disabled. A channel is estimated between the eNB and the UE for link adaptation in Transmission Mode 9 (TM9) based on CSI-RS by the UE and SRS by the eNB. CQI is calculated at UE such that if a number of CSI-RS antenna ports equals one, TM9 transmission from the eNB to the UE uses a predetermined single antenna port. If the number of CSI-RS antenna ports equals two, TM9 transmission from the eNB to the UE uses transmit diversity. If the number of CSI-RS antenna ports does not equal one or two, TM9 transmission from the eNB to the UE uses spatial multiplexing based on a rank-1 precoder that is determined from a wideband channel covariance matrix R.

An apparatus and method for the flexible configuration of uplink and downlink ratio by exchanging information relating to user traffic pattern among eNodeBs in a wireless communications network using the X2 interface is disclosed herein. In one embodiment, the information exchanged among the eNodeBs comprises downlink subframe transmission power information and uplink subframe reception power information. In another embodiment, the information exchanged among the eNodeBs comprises downlink subframe loading information and uplink subframe loading information. The exchange of such information facilitates implementation of a flexible or dynamic configuration of the uplink and downlink ratio.

An apparatus and method for providing configuration information relating to an extension carrier within a wireless communications network is disclosed herein. In one embodiment, each enhanced node B (eNodeB) transmits the configuration information within the downlink subframes of at least one radio frame, wherein the configuration information is transmitted on the downlink shared channel (DL-SCH) included in the radio frame. In another embodiment, each eNodeB transmits the configuration information within a radio resource control (RRC) signaling included in at least one radio frame to select ones of the user equipments (UEs) in response to the system load relative to the select UE's request.
摘要:
Briefly, in accordance with one or more embodiments, a base transceiver station such as an Enhanced Node B allocates a first bandwidth for operation with a first set of remote devices which may comprise user equipment (UE), and allocates at least one or more bandwidth segments outside of the first bandwidth for operation with a second set of remote devices which mag comprise user equipment (UE). Remote devices of the first set are capable of operating within the first bandwidth, and remote devices of the second set are capable of operating within the first bandwidth and within the bandwidth segments outside of the first bandwidth. The devices of the first set comprise legacy devices, and devices of the second set comprise advanced devices.
摘要:
Technology for performing multiple timing advances in a carrier aggregation communication system is disclosed. A method comprises communicating a random access preamble from a UE to an eNodeB via a PCell associated with a selected component carrier of the carrier aggregation. A Random Access Response (RAR) is received at the UE from the eNodeB for the PCell. The RAR contains a timing advance adjustment instructing the UE to adjust a timing of a PCell wireless communication. A request is received at the UE to adjust a timing of an SCell communication. A random access preamble is communicated to the UE via the SCell. An RAR is received at the UE from the eNodeB for the SCell to adjust a timing advance of the SCell wireless communication.
