摘要:
A method and apparatus are provided for jointly encoding bits containing information about an existing modulation technique or an existing antenna transmission technique in order to extend signaling to include new information about an additional modulation technique or the use of an additional antenna transmission technique without having to increase the number of bits transmitted in the signaling; and conveying the new information in unused combinations of the encoded bits. The signaling may take the form of a high speed shared control channel (HS-SCCH) that forms part of a high speed downlink packet access (HSDPA). In some embodiments, the existing modulation technique may include quadrature phase shift keying (QPSK), 16 quadrature amplitude modulation (16QAM), or some combination thereof, and the additional modulation technique may include 64 quadrature amplitude modulation (64QAM).

The use of the STTD is enabled in a network so that the common channels (CPICH etc.) do not need to be transmitted using transmit diversity, but the STTD can be enabled only for channels having dedicated pilots and which are intended for the UEs supporting this functionality. Other UEs not supporting transmit diversity can use the common channels as usual. In normal transmit diversity operation the UE will use the CPICH transmitted from both antennas as a phase reference. In the proposed method some of the common channels including CPICH are transmitted without transmit diversity even though the STTD is used on channels having dedicated pilots and which are intended for the UEs supporting this functionality.

An apparatus, method, system and software product are for receiving a broadcast service or a multicast service. User equipment receives information about transmissions of data for a broadcast or multicast. The data is transmitted in non-overlapping signals from a plurality of cells. The user equipment then uses this information to attempt to decode at least one of the signals, if decoding another of the signals failed.
摘要:
A method and corresponding equipment by which a wireless communication terminal is able to determine whether to obey or ignore a power change command from a base station, in case of the wireless communication terminal gating its uplink of data or control information to the base station, causing the base station to erroneously base some power control commands on simply noise and interference. A corresponding method for operation of a base station is also provided, and corresponding equipment.

The specification and drawings present a new method, system, apparatus and software product for communications, e.g., wireless communications, for defining a power in a discontinuous control signal after a transmission gap for an uplink control channel, e.g., dedicated physical control channel (DPCCH), wherein the power in the discontinuous control signal after the transmission gap is determined, using a predetermined criterion, by control information (e.g., regarding an allowed power window) and by a length of a transmission gap for the uplink control channel or of a further transmission gap in an uplink discontinuous data signal.

In accordance with an example embodiment of the present invention, there is provided an apparatus configured to receive a location update reject message and to determine whether a radio resource connection release message is issued in connection with the location update reject message. The apparatus is further configured to, responsive to a determination that a radio resource connection release message is issued in connection with the location update reject message, initiate an attach procedure using a new radio resource connection, and responsive to a determination that no radio resource connection release message is issued in connection with the location update reject message, to initiate an attach procedure using an existing radio resource connection.
摘要:
A method for controlling interference is described. The method includes receiving an indication that a first carrier is not received by a first base station and a second carrier is received by the first base station (610). Assigning a maximum transmission power for the first carrier so as not to exceed a transmission power for the second carrier is also included (620). The method also includes simultaneously transmitting from a UE on at least the first carrier and the second carrier. Transmitting on the first carrier is performed in accordance with the maximum assigned transmission power (630). Apparatuses and computer readable media are also described.

In accordance with an example embodiment of the present invention, a method comprises receiving a plurality of reference signals (RS) from a plurality of nearby cells over a positioning time window comprising a plurality of positioning occasions; grouping the received reference signals into a set of RS groups based on a time difference between a minimum expected RS time difference (RSTD) and a maximum expected RS time difference of the received signals; buffering a subset of the set of RS groups of the received reference signals in a RS buffer whose size is based at least in part on a buffering margin and is smaller than a maximum possible time difference; measuring the buffered reference signals; and generating an observed time difference of arrival (OTDOA) report based on the buffered subset of the set of RS groups of the received reference signals.
