Abstract

In the present invention, a user equipment (UE) receives semi-persistent scheduling (SPS) configuration information on N SPS resource configurations, where N is an integer larger than 1. The UE transmits an SPS status information indicating activation or deactivation status for each of the N SPS resource configurations.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] Pursuant to 35 U.S.C. § 119(e), this application claims the benefit of U.S. Provisional Patent Application Ser. Nos. 62 / 359,700, filed on Jul. 7, 2016, and 62 / 359,701, filed on Jul. 7, 2016, the contents of which are all hereby incorporated by reference herein in their entirety.TECHNICAL FIELD

[0002] The present invention relates to a wireless communication system, and more particularly, to a method for receiving downlink signals and an apparatus therefor.BACKGROUND ART

[0003] As an example of a mobile communication system to which the present invention is applicable, a 3rd Generation Partnership Project Long Term Evolution (hereinafter, referred to as LTE) communication system is described in brief.

[0004] FIG. 1 is a view schematically illustrating a network structure of an E-UMTS as an exemplary radio communication system. An Evolved Universal Mobile Telecommunications System (E-UMTS) is an advanced version of a conventional Universal Mobile...

Examples

example a.1

[0204]Each field of an SPS command is associated with each of the SPS patterns and indicates Activation / Release of the associated SPS pattern. The following table shows an example of a SPS command for multiple SPS patterns according to Example A.1 of the present invention.

TABLE 8P8P7P6P5P4P3P2P1

[0205]Referring to Table 8, the SPS command includes Pi field, where Pi field indicates whether the SPS pattern with SPS pattern indicator i is to be Activated or to be Released. For example, Pi is set to 1 if the SPS pattern i is to be Activated, and set to 0 if the SPS pattern i is to be Released.

[0206]The SPS command may be a fixed size of signaling depending on the number of SPS patterns. For example, the SPS command may be 1 byte if the highest SPS pattern indicator is 8, 2 bytes if the highest SPS pattern indicator is 16. In this case, no length indicator may be included in the corresponding subheader.

[0207]The SPS command may be a variable size of signaling depending on the number of S...

example a.2-1

[0209]The SPS command includes explicitly the SPS pattern indicator field and Activation / Release indicator field. The SPS command includes all SPS patterns of which state is to be changed. The following tables shows an example of an SPS command for multiple SPS patterns according to Example A.2-1 of the present invention.

TABLE 9Pattern iA / RPattern jA / RPattern kA / RPattern mA / R

[0210]Table 9 shows an SPS command including Activation / Release indicator for an even number of SPS patterns. The following table shows an another example of an SPS command for multiple SPS patterns according to Example A.2-1 of the present invention.

TABLE 10Pattern iA / RPattern jA / RPattern kA / RRRRR

[0211]Table 10 shows an SPS command including Activation / Release indicator for an odd number of SPS patterns.

[0212]Referring to Table 9 and 10, the SPS command may include 3 bits of SPS pattern indicator field. The SPS command may include 1 bit of A / R field which indicates whether the corresponding SPS pattern is to be...

example a.2-2

[0214]The SPS command includes explicitly the SPS pattern indicator field and Activation / Release indicator field. The SPS command includes only one SPS pattern of which state is to be changed. The following table shows an example of an SPS command for multiple SPS patterns according to Example A.2-2 of the present invention.

TABLE 11Pattern iA / RRRRR

[0215]Referring to Table 11, the SPS command may include 3 bits of SPS pattern indicator field. The SPS command may include 1 bit of A / R field which indicates whether the corresponding SPS pattern i is to be Activated or to be Released. For example, the A / R field is set to 1 if the corresponding SPS pattern is to be Activated, and set to 0 if the corresponding SPS pattern is to be Released. The SPS command may be a fixed size of signaling. The SPS command includes only one SPS pattern that is to be Activated or Released. For example, the length of the SPS command is fixed to one byte.

[0217]In response to the SPS command, the UE gener...
