METHOD FOR CONFIGURING PHYSICAL CHANNEL START SYMBOLS BASE STATION AND USER EQUIPMENT

Abstract

The present disclosure provides a base station. The base station comprises: a transmitting unit configured to transmit a Machine Type Communication (MTC) Physical Downlink Control Channel (M-PDCCH) and Physical Downlink Shared Channels (PDSCHs). A start Orthogonal Frequency Division Multiplexing (OFDM) symbol of a PDSCH carrying First System Information Broadcast (SIB1) is preconfigured. Respective start OFDM symbols of the M-PDCCH and other PDSCHs are configured via the SIB1. The present disclosure also provides a User Equipment (UE) and associated methods.

Claim

1.-40. (canceled)
41. A base station, comprising:
a transmitting unit configured to transmit a Machine Type Communication (MTC) Physical Downlink Control Channel (M-PDCCH) and Physical Downlink Shared Channels (PDSCHs), wherein a start Orthogonal Frequency Division Multiplexing (OFDM) symbol of a PDSCH carrying First System Information Broadcast (SIB1) is preconfigured, and respective start OFDM symbols of the M-PDCCH and other PDSCHs are configured via the SIB1.
42. The base station of claim 41, wherein
the start OFDM symbol of a PDSCH carrying SIB is �1SIBStart�, the start OFDM symbol of a PDSCH carrying paging information is �1PagingStart�, the start OFDM symbol of a PDSCH carrying a random access response is �1Msg2Start�, the start OFDM symbol of a PDSCH carrying user data is �1DataStart�, and the start OFDM symbol of the M-PDCCH is �1MPDCCHStart�.
43. The base station of claim 41, wherein
1SIBStart of the PDSCH is preconfigured or configured by a Physical Broadcast Channel (PBCH) transmitting processing unit via an MIB, and 1PagingStart, 1Msg2Start and/or 1DataStart and/or 1MPDCCHStart are configured via the SIB1 or SIB2.
44. The base station of claim 41, wherein respective values of 1SIBStart, 1PagingStart, 1Msg2Start, 1DataStart and 1MPDCCHStart are all the same, partly the same, or different from each other.
45. A User Equipment (UE), comprising:
a receiving unit configured to receive a Machine Type Communication (MTC) Physical Downlink Control Channel (M-PDCCH) and Physical Downlink Shared Channels (PDSCHs), wherein a start Orthogonal Frequency Division Multiplexing (OFDM) symbol of a PDSCH carrying First System Information Broadcast (SIB1) is preconfigured, and respective start OFDM symbols of the M-PDCCH and other PDSCHs are obtained via the SIB1.
46. The UE of claim 45, wherein
the start OFDM symbol of a PDSCH carrying SIB is �1SIBStart�, the start OFDM symbol of a PDSCH carrying paging information is �1PagingStart�, the start OFDM symbol of a PDSCH carrying a random access response is �1Msg2Start�, the start OFDM symbol of a PDSCH carrying user data is �1DataStart�, and the start OFDM symbol of the M-PDCCH is �1MPDCCHStart�.
47. The UE of claim 45, wherein
1SIBStart of the PDSCH is obtained by means of preconfiguration or by a Physical Broadcast Channel (PBCH) receiving processing unit via an MIB, and 1PagingStart, 1Msg2Start and/or 1DataStart and/or 1MPDCCHStart are obtained via the SIB1 or SIB2.
48. The UE of claim 45, wherein respective values of 1SIBStart, 1PagingStart, 1Msg2Start, 1DataStart and 1MPDCCHStart are all the same, partly the same, or different from each other.
49. A method performed by a base station, comprising:
preconfiguring a start Orthogonal Frequency Division Multiplexing (OFDM) symbol of a Physical Downlink Shared Channel (PDSCH) carrying First System Information Broadcast (SIB1); and configuring respective start OFDM symbols of a Machine Type Communication (MTC) Physical Downlink Control Channel (M-PDCCH) and other PDSCHs via the SIB1.
50. The method of claim 49, wherein
the start OFDM symbol of a PDSCH carrying SIB is �1SIBStart�, the start OFDM symbol of a PDSCH carrying paging information is �1PagingStart�, the start OFDM symbol of a PDSCH carrying a random access response is �1Msg2Start�, the start OFDM symbol of a PDSCH carrying user data is �1DataStart�, and the start OFDM symbol of the M-PDCCH is �1MPDCCHStart�.
51. The method of claim 49, wherein
1SIBStart of the PDSCH is preconfigured or configured via an MIB, and 1PagingStart, 1Msg2Start and/or 1DataStart and/or 1MPDCCHStart are configured via the SIB1 or SIB2.
52. The method of claim 49, wherein respective values of 1SIBStart, 1PagingStart, 1Msg2Start, 1DataStart and 1MPDCCHStart all the same, partly the same, or different from each other.
53. A method performed by a User Equipment (UE), comprising:
preconfiguring a start Orthogonal Frequency Division Multiplexing (OFDM) symbol of a Physical Downlink Shared Channel (PDSCH) carrying First System Information Broadcast (SIB1); and obtaining respective start OFDM symbols of a Machine Type Communication (MTC) Physical Downlink Control Channel (M-PDCCH) and other PDSCHs via the SIB1.
