Description

Method and device in wireless communication
Technical Field
The present invention relates to a method and apparatus for a wireless communication system, and more particularly, to a transmission method and apparatus for supporting variable signaling ID (Identity) in a cellular network system.
Background
In a conventional 3GPP-3rd Generation partnership Project (3GPP-3rd Generation Partner Project) Long Term Evolution (LTE-Long Term Evolution) system, an MBSFN (multicast Broadcast single frequency Network) subframe (M subframe for short) is defined. In the conventional 3GPP release, a System Frame (System Frame) includes 10 subframes (Subframe) numbered as { #0, #1, #2, #3, #4, #5, #6, #7, #8, #9}, and only { #1, #2, #3, #6, #7, #8} of the subframes can be configured as M subframes in an FDD (Frequency division duplex) mode for example, in view of guaranteeing transmission of System messages such as broadcast information. The M subframe is mainly used for transmitting an MBMS (Multimedia Multicast Service) Service. In the M subframe, the broadcast multicast service cannot be multiplexed with other unicast services.
In Release 13, a new MBMS service transmission mode, SC-PTM (Single Cell Point to multipoint) is introduced. Compared with the conventional MBMS transmission mode, the SC-PTM has the greatest difference that the MBMS service is transmitted on a PDSCH (Physical downlink Shared Channel) instead of a PMCH (Physical Multicast Channel), and further the MBMS service is not limited to be transmitted on an M subframe.
In 3GPP RAN plenum #72 conference, both fertc (funther Enhanced Machine type communication) and Enhanced NB-IOT (narrow band Internet of things) are listed as new WI (Work Item) of Release 14, wherein an important aspect is that eMTC users and NB-IOT users need to support MBMS service under SC-PTM architecture.
Disclosure of Invention
In the SC-PTM system of Release 13, the following two logical channels are introduced:
-SC-MCCH (Single Cell Multicast Control Channel );
-SC-MTCH (Single Cell Multicast Transport Channel );
the former is used for transmitting control information of the MBMS service, and a Scrambling (Scrambling) manner is related to an SC-RNTI (Single Cell Radio Network temporary Identity). The latter is used for transmitting data information of MBMS, and the scrambling mode is related to G-RNTI (Group Radio Network temporary identity). The SC-MCCH and the SC-MTCH are both transmitted in the PDSCH, and the frequency domain resources occupied by the SC-MCCH and the SC-MTCH are respectively indicated by an independent PDCCH (Physical Downlink Control Channel) or EPDCCH (enhanced Physical Downlink Control Channel). And when the SC-MCCH or SC-MTCH has transmission errors, the base station retransmits the SC-MCCH or SC-MTCH so as to ensure the receiving quality of the UE. In conventional SC-PTM, the transmission of SC-MCCH is Cell-specific, while SC-MTCH is Group-specific. Within one cell (or one group), the SC-MCCH (or SC-MTCH) uses the same higher layer configuration.
For MTC and NB-IOT, one important application scenario is CE (Coverage Enhancement). Under CE, users in one cell receiving MBMS simultaneously may be in different coverage conditions, and the Number of repetitions (repetition Number) of transmission required by different UEs is different. When SC-PTM needs to be implemented, a simple way is that all SC-PTM transmissions need to use the same repetition number, and then the system always performs initial transmission and retransmission based on the UE with the largest repetition number in the cell (or in the group), so obviously there is a waste of resources and a lower spectral efficiency is caused. And because the time domain positions of SC-MTCH and SC-MCCH transmission are configured through high-level signaling, the scheduling flexibility of the method is poor.
The present invention provides a solution to the above problems. It should be noted that the embodiments and features of the embodiments of the present application may be arbitrarily combined with each other without conflict. For example, embodiments and features in embodiments in the UE of the present application may be applied in a base station and vice versa. It is further noted that although the original intention of the invention is to address the application scenario of SC-PTM, the solution of the invention can also be used for unicast transmissions, as well as for broadband transmissions.
The invention discloses a method in UE supporting variable signaling ID, which comprises the following steps:
-step a. receiving first signaling, the first signaling comprising scheduling information of a first wireless signal;
-step b. receiving second signaling, the second signaling comprising scheduling information for the second radio signal.
The first signaling is associated with a first ID, the second signaling is associated with a second ID, the first ID and the second ID are integers respectively, and the first ID and the second ID are not equal. A first block of information bits is used to generate the first wireless signal, the first block of information bits is used to generate the second wireless signal. The first block of information bits comprises a positive integer number of bits. The scheduling information of the first wireless signal and the scheduling information of the second wireless signal respectively include at least one of { MCS (Modulation and Coding Status, Modulation and Coding state), NDI, RV (redundancy version), HARQ (Hybrid Automatic Repeat reQuest) process number, occupied time-frequency resource }.
The above method is advantageous in that the first wireless signal and the second wireless signal may be associated with different IDs, and both the first wireless signal and the second wireless signal are generated by the first information bit block. When the second wireless signal is used as the HARQ retransmission of the first wireless signal, the base station can more flexibly configure the time-frequency resource and the repetition frequency for transmitting the second wireless signal, thereby improving the overall performance of the system.
As an embodiment, the variable signaling ID refers to an ID associated with scheduling signaling of different data transmissions in one HARQ process, which is variable.
As one embodiment, the logical channel of the first wireless signal is SC-MCCH or SC-MTCH, the second wireless signal is retransmission of the first wireless signal, and the second ID corresponds to C-RNTI (Cell Radio network temporary Identity).
The embodiment has the advantage that when a plurality of UEs with different coverage requirements exist in the cell of the UE, for example, CE scenes in eMTC or NB-IOT, and the UEs all perform SC-PTM-based MBMS service reception. And the first wireless signal carries out the configuration of repeated transmission times according to the UE with the worst signal-to-noise ratio in all the UEs. When the UE has the condition of incorrect decoding, the base station only needs to configure the dedicated transmission times of the UE according to the UE signal-to-noise ratio without the correct decoding in the retransmission process, and does not need to configure the transmission times according to the worst signal-to-noise ratio, so that the spectrum efficiency and the scheduling flexibility are improved.
