stop processing the first data received from the plurality of logical channels, and
process third data received from a logical channel of the plurality of logical channels.
7 . The method of claim 1 , the reconfiguring comprising:
changing the receiving RLC entity; or
changing to a second receiving RLC entity.
8 . A first apparatus, comprising:
at least one processor; and

reconfiguring a receiving radio link control (RLC) entity of the first apparatus to process first data received from a plurality of logical channels in accordance with the signaling message, the receiving RLC entity being configured to process second data received from a first logical channel of the plurality of logical channels prior to being reconfigured, the reconfiguring comprising:
configuring a second logical channel of the plurality of logical channels; and
enabling logical channel aggregation of the first logical channel and the second logical channel, wherein the receiving RLC entity is configured to process the first data received from the first logical channel and the second logical channel.
9 . The first apparatus of claim 8 , the signaling message indicating a reconfiguration with a reestablishment of the receiving RLC entity.
10 . The first apparatus of claim 8 , the signaling message indicating a reconfiguration without a reestablishment of the receiving RLC entity.
11 . The first apparatus of claim 8 , a logical channel of the plurality of logical channels being associated with respective transmitting RLC entities of the second apparatus which transmit the first data.
12 . The first apparatus of claim 8 , the reconfiguring comprising:
configuring the first logical channel and the second logical channel of the plurality of logical channels; and
enabling the logical channel aggregation of the first logical channel and the second logical channel, wherein the receiving RLC entity is configured to process the first data received from the first logical channel and the second logical channel.
13 . The first apparatus of claim 8 , the operations further comprising:
receiving, from the second apparatus, a second signaling message; and
disabling logical channel aggregation in accordance with the second signaling message, wherein the receiving RLC entity is configured to:
stop processing the first data received from the plurality of logical channels, and
process third data received from a logical channel of the plurality of logical channels.
14 . The first apparatus of claim 8 , the reconfiguring comprising:
changing the receiving RLC entity; or
changing to a second receiving RLC entity.
15 . A non-transitory computer-readable medium having instructions stored thereon that, when executed by a first apparatus, cause the first apparatus to perform operations, the operations comprising:
receiving, from a second apparatus, a signaling message; and
reconfiguring a receiving radio link control (RLC) entity of the first apparatus to process first data received from a plurality of logical channels in accordance with the signaling message, the receiving RLC entity being configured to process second data received from a first logical channel of the plurality of logical channels prior to being reconfigured, the reconfiguring comprising:
configuring a second logical channel of the plurality of logical channels; and
enabling logical channel aggregation of the first logical channel and the second logical channel, wherein the receiving RLC entity is configured to process the first data received from the first logical channel and the second logical channel.
16 . The non-transitory computer-readable medium of claim 15 , the signaling message indicating a reconfiguration with a reestablishment of the receiving RLC entity.
17 . The non-transitory computer-readable medium of claim 15 , the signaling message indicating a reconfiguration without a reestablishment of the receiving RLC entity.
18 . The non-transitory computer-readable medium of claim 15 , a logical channel of the plurality of logical channels being associated with respective transmitting RLC entities of the second apparatus which transmit the first data.
