Embodiment 1

[0022] An embodiment of the present application provides a mobile communication network (including but not limited to a 5G mobile communication network), and the network architecture of the network may include network-side devices (such as base stations) and terminals. This embodiment provides a time-domain resource allocation method that can run on the above-mentioned network architecture. It should be noted that the operating environment of the above-mentioned time-domain resource allocation method provided in the embodiment of the present application is not limited to the above-mentioned network architecture. .

[0023] The method embodiment provided in Embodiment 1 of the present application may be executed in a mobile terminal, a computer terminal, or a similar computing device. Taking running on a mobile terminal as an example, figure 2 It is a block diagram of the hardware structure of a mobile terminal of a time domain allocation method according to an embodiment of ...

specific Embodiment 1

[0115] This embodiment describes the method of determining the adopted default time-domain resource allocation table based on the search space configuration.

[0116] In this embodiment, for other transmission information (including such as paging information paging (that is, the PDSCH that carries the paging message), other system information OSI (that is, the PDSCH that carries the OSI), random access (that is, the random access that carries the random access process Incoming response PDSCH, or PDSCH carrying MSG4 in the random access process), etc.), when the time domain resource allocation table is not configured, the default method for determining the time domain resource allocation table.

[0117] Table 4 is the application table 1 of the PDSCH time domain resource allocation table according to another embodiment of the present application. As shown in Table 4, taking OSI (that is, the RNTI type is SI-RNTI, and the PDCCH search space is Type0A common) as an example, when ...

specific Embodiment 2

[0128] This embodiment describes a method for determining the adopted default time-domain resource allocation table based on the control resource set (CORESET, COntrol REsource SET) configuration.

[0129] In this embodiment, for other transmission information (such as paging information paging (that is, the PDSCH that carries the paging message), other system information OSI (that is, the PDSCH that carries the OSI), random access (that is, the random access that carries the random access process) response PDSCH, or the PDSCH carrying MSG4 in the random access process), etc.), when the time domain resource allocation table is not configured, the default method for determining the time domain resource allocation table.

[0130] Table 5 is the PDSCH time-domain resource allocation table application table 2 according to another embodiment of the present application. As shown in Table 5, we take OSI (that is, the RNTI type is SI-RNTI, and the PDCCH search space is Type0A common) a...

Abstract

The invention provides a time domain resource allocation method and device. The method comprises the steps that a terminal can obtain at least one piece of first information, wherein the first information can comprise search space configuration information, control resource set configuration information and bandwidth part types, and a PDSCH time domain resource allocation table is determined subsequently according to the first information and a multiplexing mode between a SSB and a CORESET. Through adoption of the scheme, the problem that a scheme for allocating time domain resources to a physical downlink shared channel is incomplete in the related technology is solved, and the terminal can determine the PDSCH time domain allocation table according to the scheme and further select the PDSCH time domain allocation mode.

Description

technical field [0001] The present application relates to but is not limited to the communication field, and in particular, relates to a time domain resource allocation method and device. Background technique [0002] With the continuous advancement of radio technology, a large number of various radio services have emerged, and the spectrum resources on which radio services rely are limited. Facing the continuous increase in people's demand for bandwidth, traditional commercial communications mainly use 300MHz~3GHz Spectrum resources are extremely tense, which cannot meet the needs of future wireless communications. [0003] In future wireless communication, carrier frequencies higher than those used in the fourth-generation (4G) communication system will be used for communication, such as 28GHz, 45GHz, etc. This high-frequency channel has a large free propagation loss. The shortcomings of being easily absorbed by oxygen and being greatly affected by rain attenuation have s...
