Signal Encoding Method and Device, Method for Encoding Joint Feedback Signal

Номер: US20120002658A1

Автор: Jing Li, Shuju Fan, Xueli Ma, Zongjie Wang

Принадлежит: Huawei Technologies Co Ltd

A signal encoding method and device and a method for encoding a joint feedback signal are provided. The signal encoding method includes the following steps. When two carriers are configured with multiple-input and multiple-output (MIMO), Hybrid Automatic Repeat Request-Acknowledgement (HARQ-ACK) signals of the two carriers are combined into a joint feedback signal. The joint feedback signal is mapped into a codeword according to a predetermined mapping relationship between signals and codewords. Therefore, through the method for combining and encoding feedback signals of two carriers for transmission on a code channel in a dual cell (DC)-MIMO mode, bit error ratio (BER) and detection error cost are decreased, power overhead is saved, and a cubic metric (CM) value of the system is not affected, thereby enhancing the performance of the system.

Power save mechanism for wireless communication devices

Номер: US20120014305A1

Автор: Jakub Majkowski, Naveen Kakani

Принадлежит: Nokia Oyj

Method, apparatus, and computer program product embodiments are disclosed to enable power save modes of operation between mobile wireless devices for direct data transfer in an infrastructure BSS. An example embodiment inserts in a message that is transmitted by the transmitting mobile wireless device, a specified time when a next active direct data transfer period will start so that the devices can remain in power save mode in a direct data transfer link until that time. Then, when the next active direct data transfer period is about to start, the receiving device sends a trigger signal based on the specified time, the trigger signal indicating that the next period is about to start. This confirms to the transmitting device that the receiving device has awakened, so that the transmitting device may start transmitting the data to the receiving device via the direct data transfer link.

A disclosed example method involves sending a first assignment message indicative of first radio block periods assigned to the mobile station for downlink communications. At least one of the first assigned radio block periods is separated from a next occurring one of the first assigned radio block periods by at least a first non-assigned radio block period. In addition, the example method involves sending a second assignment message indicative of second radio block periods assigned to the mobile station for uplink communications. At least one of the second assigned radio block periods is separated from a next occurring one of the second assigned radio block periods by at least a second non-assigned radio block period. The example method also involves sending an uplink allocation indicator to the mobile station during one of the first radio block periods assigned for downlink communications with the mobile station.

Method of channel management for multiple component carrier in mobile communication system

Номер: US20120039200A1

Автор: Jae Heung Kim, Kook Jin Lee, Kyoung Seok Lee

Принадлежит: Electronics and Telecommunications Research Institute ETRI

Disclosed are channel management methods in a multicarrier structure in a mobile communication system. Uplink (UL) and downlink (DL) channel management methods in a carrier aggregation environment are used as the channel management methods. In DL, a base station determines a component carrier (CC) of an unstable radio channel state, stops data retransmission by the CC, and notifies a terminal of retransmission stop. In UL, the base station determines a CC of an unstable radio channel state and instructs the terminal to stop data retransmission by the CC, and the terminal stops the data retransmission and initializes a retransmission buffer. Using the channel management methods in the mobile communication system employing the multicarrier structure, an increase in the number of unnecessary retransmissions is prevented, so that unnecessary retransmission and power consumption of the terminal can be reduced and the waste of radio resources and the degradation of base station performance due to unnecessary retransmission can be prevented.

In one aspect, a wireless device sends a synchronisation group identifier to a network control apparatus identifying a synchronisation group of wireless devices. If the wireless device is notified that no other devices of the synchronisation group are connected to the control apparatus, the wireless device transmits a timing reference to and agrees an extended discontinuous reception time period with the control apparatus. Otherwise, the wireless device receives a timing reference and an extended discontinuous reception time period from the control apparatus. The wireless device periodically enters an idle state and powers up for reception in accordance with at least the timing reference and the extended discontinuous reception time period. In another aspect, plural base stations each use a common timing reference and a common extended discontinuous reception time period in controlling the operation of extended discontinuous reception by a synchronisation group of wireless devices.

If a communication (e.g., transmission) attempt fails (e.g., by a wireless station (STA), smart meter station (SMSTA), etc.), then a backoff snooze countdown may be performed before a subsequent communication is attempted. Also, if communication activity is detected on the communication medium, then such a backoff snooze countdown may be performed before monitoring the communication medium or a subsequent communication attempt is made. Such a backoff snooze countdown may be based on a codeword value (e.g., such as provided within a beacon received from an access point (AP)), and different respective backoff snooze countdowns may be made based on different respective codeword values.

Correction of clock errors in a wireless station to enable reduction of power consumption

Номер: US20130272180A1

Принадлежит: Gainspan Corp

According to an aspect, a wireless station uses a low-frequency clock during sleep intervals and a high-frequency clock during awake intervals. Drift between the low-frequency clock and the high-frequency clock are corrected to enable aligning a wake time instant of the wireless receiver with start of beacon transmissions from an access point, and thereby to reduce power wastage. According to another aspect, errors between the clock of an access point and that of a wireless station are corrected. The wireless station computes an error between the clocks, and extrapolates the error for a sleep interval to compute a wake-up time instant. The correction and extrapolation are performed in every awake interval. Again, undesired power consumption in the wireless station is thereby reduced.

Methods and apparatus for managing radio measurements during discontinuous reception. In one exemplary embodiment, the distribution of Long Term Evolution (LTE) DRX measurements is staggered or distributed across multiple DRX cycles (which may be contiguous or non-contiguous) so as to reduce the transceiver activity and power consumption. The exemplary UE in one implementation only performs a subset of measurements during each DRX cycle. By staggering or distributing cell measurements over multiple DRX cycles, the UE can improve power consumption, while still conforming to measurement requirements.

Methods and devices for optimizing on-time throughput in a wireless network. An enhanced node B (eNodeB) integrating two or more air interfaces schedules transmissions, for a measurement period, over at least one of the two or more air interfaces. The eNodeB estimates, based on the transmissions, a metric of on-time throughput for the user equipment (UE) within the cell, where on-time throughput is a measure of an amount of data that arrives at a destination before a delay threshold has been reached and at a bit-rate greater than or equal to a target bit-rate. The eNodeB then assigns UEs within the cell to an air interface of the two or more air interface to maximize the metric of on-time throughput for the UEs within the cell.
