摘要:
Embodiments improve User Equipment (UE) positioning accuracy in a mobile communication system by providing for a UE configured to listen for Positioning Reference Signal (PRS) transmissions within an operating bandwidth around Direct Current (DC) sub-carrier and at least one non-PRS transmission including, for example, a CRS or PSS/SSS; receiving, at the UE, PRS and non-PRS(s) transmissions transmitted from base stations within the operating bandwidth; performing, at the UE, Time of Arrival (TOA) measurements for each of the plurality of base stations, wherein the TOA measurements are determined based on the at least one non-PRS transmission; obtaining Observed Time Difference of Arrival (OTDOA) measurements by subtracting TOA for the plurality of base stations from a TOA for a reference base station, and transmitting, from the UE to a Location Server (LS), the OTDOA measurements, wherein the LS performs a positioning estimation of the UE based on the OTDOA measurements.
摘要:
A network node (12) schedules a wireless communications device (14) to utilize a subsection (54) of a previously configured active bandwidth part (46). The wireless communications device (14) utilizes the subsection (54) for operations such as monitoring for control signaling from the network node (12), channel measurements, and/or for communication between the wireless communications device (14) and the network node (12) (e.g. uplink and/or downlink traffic). Accordingly, the wireless communications device (14) may reduce power consumption by not monitoring and/or using a wider bandwidth.

A method of operating an access node (112) of a sub-area (161) of a communication network (100) includes transmitting configuration data (4001) for wake-up signal (700, 711, 712, 4003) transmission in the sub-area (161) and in at least one further sub-area (162-168) of the communication network (100).
摘要:
A base station transmits, in a repetitive first sequence of transmission frames of a wireless channel, first positioning reference signals. The base station transmits, in a repetitive second sequence of transmission frames of the wireless channel, second positioning reference signals. The first positioning reference signals and the second positioning reference signals each facilitate determining a time of arrival of signals communicated on the wireless channel.
摘要:
The invention is directed to systems, methods and computer program products for discontinuous signaling in a mobile communication network. User equipment (UE)/mobile terminal requests slotted transmissions and, in response to the network authorizing slotted transmissions, communication of subsequent UE transmissions are slotted, such that a minimum time period is required to elapse between each UE transmission. In specific embodiments of the invention the minimum time period is a predetermined time period known in advance to the user equipment and network. In other embodiments of the invention the user equipment slotted transmission requests includes a requested minimum time period, which may be approved or revised by the network. In still further embodiments the network, upon receiving the request for slotted transmissions, determines the minimum time period.

摘要:
First reoccurring resources on a radio interface of a cellular network (100) are allocated and shared between communication devices (121-125) assigned to a first set (151). Second reoccurring resources on the radio interface are allocated and shared between communication devices (121-125) assigned to a second set (152). A control message is sent, the control message indicating the first reoccurring resources and the second reoccurring resources. The control message may optionally be sent employing a broadcast transmission (110).
