摘要： A pilot channel signal for time-division multiplexing with one or more traffic channel signals in a broadcast/multi-cast signal and for code-division multiplexing with a continuously transmitted pilot channel signal is described. In an exemplary method for transmitting a broadcast/multicast signal, a pilot symbol sequence is obtained for each slot of one or more frames of the broadcast/multicast signal, so that the pilot symbol sequence varies for each slot of a given frame. The pilot symbol sequence for each slot is spread with a channelization code, and the spread pilot symbol sequence for each slot is scrambled, using a scrambling code, to form a first pilot channel signal. The first pilot channel signal is transmitted so that it is time-division multiplexed with one or more traffic channel signals transmitted during each slot and code-division multiplexed with a second pilot channel signal transmitted during all slots of the one or more frames.
摘要翻译：描述了用于与广播/多播信号中的一个或多个业务信道信号进行时分复用并用于与连续发送的导频信道信号进行码分复用的导频信道信号。在用于发送广播/多播信号的示例性方法中，为广播/多播信号的一个或多个帧的每个时隙获得导频符号序列，使得导频符号序列对于给定帧的每个时隙而变化。每个时隙的导频符号序列用信道化码扩展，并且使用扰码对每个时隙的扩展导频符号序列进行加扰，以形成第一导频信道信号。发送第一导频信道信号，使其与在每个时隙期间发送的一个或多个业务信道信号进行时分复用，并与在一个或多个帧的所有时隙期间发送的第二导频信道进行码分多路复用。

摘要： A first base station provides radio communication service to user equipments, UEs, and a second base station that provides radio communication service to UEs in adjacent cell service area. The first base station receives cell range expansion, CRE, information from the second base station for expanding the size of the first cell and evaluates handover of one or more UEs with respect to the second cell based on the CRE information. In one embodiment, the second base station determines a CRE related configuration that includes the CRE information with respect to the first cell, sends the CRE information to the first base station. For example, the second base station may send a handover request including the CRE information to the first base station. The second base station also may consider CRE information in handover evaluation.

摘要： Network nodes and methods therein for inter cell interference coordination. A method in a base station BS1 comprises receiving, from a neighboring base station BS2, an indicator A, related to estimated spatial properties of a radio channel over which the neighboring base station has received a radio signal from the base station BS1. The method further comprises receiving, from a UE served by the base station, an indicator B related to estimated spatial properties of a radio channel over which the UE has received a radio signal from the base station BS1. The method further comprises determining a correlation based on indicator A and indicator B; and adapting a transmission to the UE, based on properties of the correlation. By performing the method, the base station BS1 enables control of interference subjected towards the neighboring base station BS2 caused by downlink transmission to the UE.

摘要： A method in a first base station for assisting a third base station in scheduling a user equipment. The first base station obtains a first parameter associated to a first cell, or an indication of the first parameter, and identifier of the first cell. The first parameter comprises a first protected subframe pattern. The first base station obtains a second parameter associated to a second cell, or indication of the second parameter, and an identifier of the second cell. The second parameter comprises a second protected subframe pattern. The first base station assists the third base station in scheduling of the user equipment in a third cell by sending to the third base station the first parameter, or the indication of the first parameter, and the identifier of the first cell, together with the second parameter, or the indication of the second parameter, and the identifier of the second cell.
