CPC H04B 7/0695 (2013.01) [H04W 74/02 (2013.01); H04W 74/0841 (2013.01); H04W 76/19 (2018.02); H04W 80/02 (2013.01)] | 17 Claims |
1. A beam failure processing method, comprising:
determining, by a terminal based on a beam failure detection reference signal (BFD RS) resource group, whether a beam failure occurs in a first cell group,
wherein the BFD RS resource group is configured in the first cell group; and
sending, by the terminal, a beam failure recovery request message to a network side device in a case that a beam failure occurs in the first cell group;
wherein the sending, by the terminal, a beam failure recovery request message to a network side device comprises:
sending, by the terminal, the beam failure recovery request message to the network side device in a first cell,
wherein the first cell is a cell connected to the terminal;
wherein in a case that a primary cell and a secondary cell that are connected to the terminal are in a same frequency band,
the first cell comprises the secondary cell outside the first cell group or a second cell group in cells connected to the terminal and the first cell meets at least one of the following:
being the secondary cell associated with the first cell group or the second cell group; or
being the secondary cell indicated by a network side; or
being the secondary cell selected from a plurality of secondary cells configured by a network side; or
being the secondary cell in a same frequency band with the first cell group or the second cell group; or,
wherein in a case that the primary cell connected to the terminal is in a first frequency range and the secondary cell connected to the terminal is in a second frequency range, or the primary cell and the secondary cell that are connected to the terminal are in different frequency bands in the second frequency range,
wherein the first frequency range is less than the second frequency range; and
the first cell comprises any of the following:
the primary cell;
a cell in a same frequency band with the first cell group or the second cell group,
wherein the second cell group is a cell group configured with a candidate beam RS resource group;
the secondary cell in a frequency band in the second frequency range other than a frequency band in which the first cell group or the second cell group is located; and
a preset cell in a fourth cell group.
