Embodiment 1

[0246] In this embodiment, a transport channel ID (Transport channel ID) is described in detail.

[0247] In this embodiment, a transmission channel identifier is set for each transmission channel. The transmission channel identifier is unique in the terminal and can be used to configure other configuration information of the transmission channel. The other configuration information of the transmission channel may include transmission channel priority. level, transport format set (Transport Format Set, TFS), or modulation and coding strategy (Modulation and Coding Scheme, MCS) and so on.

[0248] As shown in Table 1 below, it is an example of the configuration of the transmission channel identifier.

[0249] transport channel identifier

[0250] Table 1

Embodiment 2

[0252] This embodiment describes in detail the TTI information or the numerology information supported by the transport channel.

[0253] Each transport channel can support one or more TTIs or numerologies. The TTIs or numerologies supported on different transport channels may be partially the same or all the same or completely different. When a transport channel supports multiple TTIs or numerology, it is also possible to set a priority for each TTI or numerology. Of course, the priority may not be configured.

[0254] Table 2 below is an example of the configuration of the number information supported by the transmission channel. In this example, there are at least three numbers configured: number 1, number 2, and number 3, where N1 is used to represent number 1, N 2 is used to represent number 2, and N 3 is used to represent number 3.

Embodiment 3

[0267] This embodiment describes in detail the LCP configuration information corresponding to each numerology.

[0268] In an implementation manner, the configuration method of the LC processing priority corresponding to each numerology supported by the transmission channel may be: configure the LC list supported by each numerology according to the priority order. Corresponding priority relationship. Table 5 below is an example of the LCP configuration information corresponding to each numerology when this configuration method is adopted.

[0269] In another implementation manner, the configuration method of the LC processing priority corresponding to each numerology supported by the transmission channel may be: configure a priority for each LC supported in each numerology. Get a relative priority relationship. Table 7 below is an example of the LCP configuration information corresponding to each numerology when this configuration method is adopted.

Abstract

The invention discloses a method and a device for configuring a system parameter set. The method comprises the following steps: configuring a MAC parameter sub-set at a MAC layer, wherein the MAC parameter sub-set at least comprises one as follows: a MAC parameter sub-set identifier, MAC parameter sub-set priority, transmission time interval TTI information or numerology information supported by the MAC parameter sub-set, LCP configuration information corresponding to each system parameter set, a mapping relationship between a logical channel and the MAC parameter sub-set, DRX configuration information corresponding to each system parameter set, hybrid automatic retransmission request HARQ configuration information corresponding to each system parameter set, SR configuration information corresponding to each system parameter set, BSR information, configuration information related to the system parameter set in the RACH process, configuration information of SPS related to the system parameter set, MAC data packet format configuration information and PHR report configuration information. The method and the device for configuring a system parameter set in the invention enable each function to operate normally and maximize the efficiency in the case that the MAC layer supports a plurality of numerology.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and device for configuring a system parameter set. Background technique [0002] In order to meet the demand for higher, faster and newer communications in the foreseeable future, the industry has already started research on future 5G technology. 5G will carry out further technical research in terms of greater throughput, more user connections, lower latency, higher reliability, and lower power consumption (including network-side equipment and user terminals). [0003] After the introduction of the system parameter set (numerology) in the 5G technology, how does the Media Access Control (MAC) layer maintain the normal operation of each function and maximize the performance while supporting multiple numerology to meet the different needs of different services , there is currently no effective solution. SUMMARY OF THE INVENTION [0004] In order to solve the above...
