摘要:
Methods, base stations and access terminals for uplink signalling are provided. Resource request channel characteristics such as location in time-frequency, sequence, time slot, are assigned to each access terminal to distinguish their resource requests from the resource requests of other access terminals. Access terminals make requests using a resource request on a resource request channel having the assigned characteristics. The base station can then determine which access terminal transmitted 0 the resource request based on the resource request channel characteristics of the resource request channel upon which the resource>request was received. The base station then transmits a response to the request which may for example be a new resource allocation, a default allocation or a renewal of a previous allocation.
摘要:
A method for transmitting data in a multiple-input-multiple-output space-time coded communication using a mapping table mapping a plurality of symbols defining the communication to respective antennae from amongst a plurality of transmission antennae and to at least one other transmission resource. The mapping table may comprise Alamouti-coded primary segments and may also comprise secondary segments, comprising primary segments. The primary segments in the secondary segments may be defined in accordance to an to Alamouti based code pattern applied at the segment level to define a segment-level Alamouti based code.

Embodiments of the present disclosure describe techniques and configurations for triggering a plurality of wireless devices such as Machine Type Communication (MTC) devices in a wireless communication network. A method may include receiving, by an interworking function (IWF) of a wireless communication network, a trigger from a machine type communication (MTC) server to initiate a communication between the MTC server and a plurality of MTC devices and sending, by the IWF, a triggering indication to the plurality of MTC devices using a radio access network (RAN) over a first reference point to a first module including a cell broadcast center (CBC) or over a second reference point to a second module including a mobility management entity (MME) or a serving general packet radio service (GPRS) support node (SGSN). Other embodiments may be described and/or claimed.

Embodiments of system, device, and method configurations for managing inter-radio access technology (inter-RAT) mobility of handovers between a UMTS Terrestrial Radio Access Network (UTRAN) or GSM EDGE Radio Access Network (GERAN) and an evolved UMTS Terrestrial Radio Access Network (E-UTRAN) to avoid scenarios of in-device coexistence (IDC) interference are disclosed herein. In one example, the existence and types of IDC interference with an E-UTRAN Long Term Evolution (LTE)/Long Term Evolution-Advanced (LTE-A) network are determined and communicated to the UTRAN/GERAN in an IDC indication signal. The IDC indication signal may communicate the existence and type of IDC interference occurring at user equipment, such as between licensed LTE/LTE-A and unlicensed industrial scientific medical (ISM) radio frequency bands. Accordingly, the UTRAN/GERAN may use information provided from the IDC indication signal to prevent a handover to the E-UTRAN that would result in IDC interference.
摘要:
A technology for a user equipment (UE) is disclosed that is operable in an anchor-booster architecture of a multiple radio access technology (multi-RAT) heterogeneous network (HetNet). Control information to an anchor cell can be transmitted from a wireless wide area network (WWAN) node in the multi-RAT UE. Data packets of the multi-RAT UE can be selected for transmission via one of the WWAN node and a wireless local area network (WLAN) node in the multi-RAT UE using a multi-RAT coordination function (MRCF) module. Each data packet from one of the WWAN node and the WLAN cell can be transmitted to a multi-RAT small cell evolved node B (SC-eNode B) based on the selection by the MRCF module.
摘要:
In order to minimize the control signaling overhead associated with transmitting CQI data from mobile stations to base stations in wireless communication networks supporting MU-MIMO, the CQI during MU-MIMO operation is estimated based on SU-MIMO CQI data, mobile station geometry data, and mobile station PMI (Precoding Matrix Index) data. More particularly, the base station maintains and updates a knowledge pool that correlates geometry data and learned impact of interfering precoder data to degradation of CQI values responsive to switching from SU-MIMO operation to MU-MIMO operations. Then, when the base station switches from SU-MIMO operation to MU-MIMO operation, it consults the knowledge pool to predict the degradation in CQI and subtracts them from the known, pre-switching SU-MIMO CQI feedback data for each relevant mobile station to predict the post-switching MU-MIMO CQIs for that mobile station.

A method is provided for providing an access node with a demodulation reference signal (DMRS). The method includes, when the UE and at least one relay node are present in a cell, the relay node transmitting the DMRS on a subset of a set of resource elements in which the UE transmits the DMRS.
摘要:
A wireless communication system and method for a network having a tree topology. An initial path from a base station to an end relay node is selected. The path selection includes an active communication path and a redundant communication path. The path selection is based on at least one policy factor. The at least one policy factor is monitored and the path is updated based on a change to the monitored at least one policy factor.
