TRANSITION PERIOD FOR DUAL CONNECTIVITY
Methods and apparatus, including computer program products, are provided for dual connectivity. In one aspect there is provided a method. The method may include alternating access, by a user equipment during a transition between a first base station and a second base station, to the first base station and the second base station, wherein the alternating is performed during the transition in accordance with a schedule. Related apparatus, systems, methods, and articles are also described.
1 . A method comprising:
alternating access, by a user equipment during a transition between a first base station and a second base station, to the first base station and the second base station,
wherein the alternating is performed during the transition in accordance with a schedule.
2 . The method of claim 1 , wherein the schedule is configured by radio resource control (RRC) signaling.
3 . The method of claim 1 , wherein the schedule is configured such that hybrid automatic request repeat operation can be carried in links to both the first base station and the second base station.
4 . The method of claim 1 , wherein the transition is preceded by a first period and followed by a second period, wherein the first period, the transition, and the second period form a time division multiple access pattern defining when the user equipment is allowed to access the first base station and the second base station.
5 . The method of claim 1 , wherein the first base station provides at least one of a primary cell, an anchor cell, a master cell, or a macrocell, and the second base station provides at least one of a secondary cell, an assisting cell, a slave cell, or a small cell.
6 . The method of claim 1 , wherein the user equipment accesses the first base station and the second base station using a single transceiver.
7 . An apparatus comprising:
at least one processor; and
at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to at least perform:
alternate access, during a transition between a first base station and a second base station, to the first base station and the second base station,
wherein the alternating is performed during the transition in accordance with a schedule.
8 . The apparatus of claim 7 , wherein the schedule is configured by radio resource control (RRC) signaling.
9 . The apparatus of claim 7 , wherein the schedule is configured such that hybrid automatic request repeat operation can be carried in links to both the first base station and the second base station.
10 . The apparatus of claim 7 , wherein the transition is preceded by a first period and followed by a second period, wherein the first period, the transition, and the second period form a time division multiple access pattern defining when the apparatus is allowed to access the first base station and the second base station.
11 . The apparatus of claim 7 , wherein the first base station provides at least one of a primary cell, an anchor cell, a master cell, or a macrocell, and the second base station provides at least one of a secondary cell, an assisting cell, a slave cell, or a small cell.
12 . The apparatus of claim 7 , wherein the apparatus accesses the first base station and the second base station using a single transceiver.
13 . A non-transitory computer-readable medium including computer program code, which when executed by at least one processor provides operations comprising:
alternating access, during a transition between a first base station and a second base station, to the first base station and the second base station,
wherein the alternating is performed during the transition in accordance with a schedule.
14 . The computer program code of claim 13 , wherein the schedule is configured by radio resource control (RRC) signaling.
15 . The computer program code of claim 13 , wherein the schedule is configured such that hybrid automatic request repeat operation can be carried in links to both the first base station and the second base station.
16 . The computer program code of claim 13 , wherein the transition is preceded by a first period and followed by a second period, wherein the first period, the transition, and the second period form a time division multiple access pattern defining when a user equipment is allowed to access the first base station and the second base station.
17 . The computer program code of claim 13 , wherein the first base station provides at least one of a primary cell, an anchor cell, a master cell, or a macrocell, and the second base station provides at least one of a secondary cell, an assisting cell, a slave cell, or a small cell.
