example 1

[0314] Example 1: Table 1 and Figure 6 It shows a possible MAC CE format that uses MAC-CE to indicate BFRQ information, and there is no B field in this format.

[0315] Such as Figure 6 As shown, the MAC-CE may include a serving cell ID field, a new beam info field, and reserved bits.

[0316] Serving cell ID field, occupying 5 bits: indicates the ID of the cell whose link indicated by the MAC-CE fails.

[0317] new beam info field, occupying 6 bits: indicating to restore the reference signal resource index of the cell whose link indicated by the serving cell ID field failed.

[0318] "R" indicates a reserved bit, which is generally set to "0".

example 2

[0321] Example 2: Table 2 and Figure 7 It shows a possible MAC CE format that uses MAC-CE to indicate BFRQ information, and there is a B field in the format.

[0322] Such as Figure 7 As shown, an Oct represents a byte composed of 8 bits, Figure 7 Include two Octs, which are recorded as Oct 1 and Oct 2 for distinction. Such as Figure 7 As shown, the MAC-CE may include a serving cell ID field, a new beam info field, a B field, and reserved bits.

[0323] Serving cell ID field, occupying 5 bits: indicates the ID of the cell whose link indicated by the MAC-CE fails.

[0324] Field B, occupying 1 bit: indicating whether the reference signal of the cell whose link failure indicated by the recovering serving cell ID field exists. Further, if the B field is "1", it means that there is a new beam info field. If the B field is "0", it means that there is no new beam info field. Certainly, the meanings of the values ​​"1" and "0" are only examples, and the present application...

[0331] Example 3: Table 3 and Figure 8 It shows a possible MAC CE format that uses MAC-CE to indicate BFRQ information, and there is no B field in this format.

[0332] Such as Figure 8 As shown, an Oct represents a byte composed of 8 bits, Figure 8 Include an Oct, denoted as Oct 1. Such as Figure 8 As shown, the MAC-CE may include a serving cell ID field, a new beam info field, and reserved bits.

[0333] Serving cell ID field, occupying 3 bits: indicates the ID of the cell whose link indicated by the MAC-CE fails.

[0334] The new beam info field, occupying 4 bits: indicates the reference signal resource index of the cell whose link failure indicated by the serving cell ID field is restored.

[0335] "R" indicates a reserved bit (Reserved bit), generally set to "0".

Abstract

The invention provides a communication method and a communication device, so as to select indication information in a proper format or select resources in a proper size for reporting when terminal equipment reports information of a cell with link failure, thereby reducing waste of reported resources. The method may comprise: a terminal apparatus determines a link failure of at least one cell; andthe terminal apparatus sends first indication information to the network apparatus, wherein the first indication information indicates information of the link failure cell, and the first indication information is determined based on the condition of the link failure cell.

Description

technical field [0001] The present application relates to the communication field, and in particular to a communication method and a communication device. Background technique [0002] During the communication process, the beam may be blocked. When the beam is blocked, the signal cannot continue to be transmitted. In the event that the beam is blocked, to prevent the communication from being interrupted suddenly, a corresponding mechanism is introduced to detect the beam quality and quickly restore the link in the event of a block. [0003] In the prior art, the terminal device will perform beam failure detection. After the terminal device determines that the beam fails, it sends beam failure recovery request (beam failure recovery request, BFRQ) information (or also called link failure recovery request information) to the network device, and the terminal device can indicate the link failure to the network device through the BFRQ information. information such as the cell i...
