SYSTEMS AND METHODS FOR RAN-WLAN AGGREGATION

TCL COMMUNICATION LIMITED...

1. A method for communication between a mobile device and a base station, wherein the mobile device is in wireless communication directly with the base station and in wireless communication with a WLAN access point, which WLAN access point is in communication with the base station, the method performed at the mobile device and comprising the steps of:configuring the mobile device according to pre-defined rules to transmit data from the mobile device to the base station directly to the base station and/or via the WLAN access point; and
transmitting data from the mobile device to the base station according to the received rules, wherein the pre-defined rules are received by the mobile device from the base station,
wherein the pre-defined rules indicate a threshold amount of data for transmission from the mobile device used to determine whether the data is transmitted directly to the base station and/or via the WLAN access point,
wherein the pre-defined rules indicate that if the mobile device has greater than the threshold amount of data for transmission to the base station, that data should be transmitted to the base station via the WLAN access point or that data should be transmitted directly to the base station; and
wherein the pre-defined rules indicate that if the mobile device determines that the amount of pending data for uplink transmission does not exceed the threshold, the data should be transmitted either to the base station or the WLAN access point.

CELLULAR COMMUNICATION SYSTEM DEVICES AND METHODS

TCL COMMUNICATION LIMITED...

1. A method for operating a wireless communication device in communication with a network element of a cellular communication system, wherein the wireless communication device has an uplink buffer for storing uplink data to be sent to the network element in an uplink grant procedure, the method comprising:skipping transmission of periodic Buffer Status Reports from the wireless communication device to the network element to which the wireless communication device is connected, when skipping of uplink padding transmissions is enabled and no uplink data is being sent, wherein periodic Buffer Status Reports are triggered by the expiration of periodic BSR-Timer, and
wherein the skipping of uplink padding transmissions is enabled based on:
the network element transmitting an indication in a DCI (Downlink Control Information) signal carried on PDCCH (Physical Downlink Control Channel), EPDCCH (Enhanced Physical Downlink Control Channel), or MPDCCH (Machine type communications Physical Downlink Control Channel) to the wireless communication device which is in communication with the network element,
wherein the indication instructs the wireless communication device to skip sending uplink padding transmissions for a given uplink grant scheduled by the DCI for dynamic scheduling grant based in part on adaptive modulation and coding.

SYSTEMS AND METHODS FOR FREQUENCY DIVISION DUPLEX COMMUNICATION

TCL COMMUNICATION LIMITED...

1. A method of wireless communication using half duplex frequency division duplex, HD-FDD, comprising at a wireless communications device:receiving downlink data during a plurality of downlink subframes; and
transmitting a hybrid automatic repeat request acknowledgement, HARQ-ACK, on an uplink;
wherein the HARQ-ACK relates to downlink data received during at least two of the plurality of downlink subframes and the HARQ-ACK is transmitted during one uplink subframe,
wherein the wireless communications device receives timing data on a downlink channel which indicates a timing association between a downlink data subframe and an uplink transmission subframe for transmitting the HARQ-ACK,
wherein the timing data is received as part of a downlink control indicator in a DCI message which is in DCI format 6-1A.

TRANSMITTING AND RECEIVING DATA USING POLAR CODES

TCL COMMUNICATION LIMITED...

1. A method for transmitting data over a physical channel using a polar code, the polar code defining a plurality of virtual channels within the physical channel and allocating a subset of the virtual channels for transmission of data, each of the subset of the virtual channels for the transmission of data being mapped to respective bits of a block of data to be transmitted, the method comprising:receiving a block of data to be transmitted;
receiving additional data to be transmitted together with the block of data;
selecting one or more, but not all, of the virtual channels which are allocated for the transmission of data as being channels for transmitting the additional data;
determining a scrambling sequence based on the additional data;
applying the scrambling sequence to those bits of the block of data which map onto the one or more of the virtual channels selected for transmitting the additional data to generate a scrambled version of the block of data; and
transmitting the scrambled version of the block of data according to the polar code, wherein error detection data is also transmitted which enables a detection of errors in the block of data.

SYSTEMS AND METHODS FOR FREQUENCY DIVISION DUPLEX COMMUNICATION

TCL COMMUNICATION LIMITED...

1. A wireless communication method performed by a wireless communication device, comprising:receiving downlink data during a plurality of downlink periods; and
transmitting a hybrid automatic repeat request acknowledgement, HARQ-ACK, on an uplink;
wherein the wireless communication device receives timing data on a downlink channel which indicates a timing association between a downlink data period and an uplink transmission period for transmitting the HARQ-ACK,
wherein the timing data is received as part of a downlink control information message, and
wherein upon detection of a PDSCH transmission within a resource n-k intended for a UE and for which a HARQ-ACK shall be provided, the UE transmits the HARQ-ACK in a period n, where k is selected based on a higher-layer parameter.
