Description

Method and apparatus for signal detection

Technical Field

The present application relates to the field of communications, and in particular, to a method and an apparatus for signal detection.

Background

User Equipment (UE) accesses a network and needs to perform cell search and acquire cell system information. A New design is adopted for Synchronization signals in New Radio (NR), and a Synchronization Signal/Broadcast Channel block (SSB) and an SSB burst set (SSB) are introduced, wherein the SSB includes an NR-Primary Synchronization Signal (PSS), an NR-Secondary Synchronization Signal (SSS), and an NR-Physical Broadcast Channel (PBCH). One SSB occupies 4 consecutive Orthogonal Frequency Division Multiplexing (OFDM) symbols, one SSB burst set is a time window with a time domain length of 5ms, and at most L SSBs can be transmitted within the 5ms SSB burst set. For different frequency bands, L has different values, for example, in a frequency band below 3GHz, L is 4; a frequency band of 3GHz-6GHz, L being 8; the frequency band of 6GHz-52.6GHz, L is 64.

After the UE completes cell search, it obtains downlink synchronization with the cell, and further needs to obtain System Information (System Information) of the cell, so as to facilitate accessing and working correctly in the cell. The Remaining Minimum System Information (RMSI) is scheduled by a Physical Downlink Control Channel (PDCCH) and transmitted in a Physical Downlink Shared Channel (PDSCH). The SSB has a mapping relationship with the RMSI CORESET, and the configuration information including the mapping relationship is included in the MIB in the SSB. Since NR supports multiple subcarrier spacings and time-domain configuration of a flexible and complicated SSB, a new design of mapping relationship between the SSB and a RMSI control channel resource set (core set) is required.

Detailed Description

The technical solution in the present application will be described below with reference to the accompanying drawings.

The technical scheme of the embodiment of the application can be applied to various communication systems, for example: a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a General Packet Radio Service (GPRS), a Long Term Evolution (Long Term Evolution, LTE) System, an LTE Frequency Division Duplex (FDD) System, an LTE Time Division Duplex (TDD), a Universal Mobile Telecommunications System (UMTS), a Worldwide Interoperability for Microwave Access (WiMAX) communication System, a future fifth Generation (5G) System, or a New Radio Network (NR), etc.

Terminal equipment in the embodiments of the present application may refer to user equipment, access terminals, subscriber units, subscriber stations, mobile stations, remote terminals, mobile devices, user terminals, wireless communication devices, user agents, or user devices. The terminal device may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with Wireless communication function, a computing device or other processing device connected to a Wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G Network or a terminal device in a future evolved Public Land Mobile Network (PLMN), and the like, which are not limited in this embodiment.

The Network device in this embodiment may be a device for communicating with a terminal device, where the Network device may be a Base Transceiver Station (BTS) in a Global System for Mobile communications (GSM) System or a Code Division Multiple Access (CDMA) System, may also be a Base Station (NodeB, NB) in a Wideband Code Division Multiple Access (WCDMA) System, may also be an evolved node b (eNB, or eNodeB) in an LTE System, may also be a wireless controller in a Cloud Radio Access Network (CRAN) scenario, or may be a relay Station, an Access point, a vehicle-mounted device, a wearable device, a Network device in a future 5G Network, or a Network device in a future evolved PLMN Network, and the like, and the embodiment of the present invention is not limited.

Fig. 1 is a schematic diagram of a communication system of the present application. The communication system in fig. 1 may comprise at least one user equipment 10 and a network device 20. The network device 20 is configured to provide a communication service to the user equipment 10 and access a core network, and the user equipment 10 accesses the network by searching for a synchronization signal, a broadcast signal, and the like transmitted by the network device 20, thereby performing communication with the network. The arrows shown in fig. 1 may represent uplink/downlink transmissions over a cellular link between the user equipment 10 and the network equipment 20.

The configuration patterns of SSB and RMSI CORESET/PDSCH include three multiplexing modes, as shown in FIG. 2. In the multiplexing mode 1, the SSB and the RMSI CORESET are positioned at different moments, and the transmission bandwidth of the SSB is partially overlapped with the initial access downlink bandwidth part of the RMSI CORESET; the multiplexing mode 2 is that the SSB and the RMSI CORESET are positioned at different moments, and the transmission bandwidth of the SSB does not have an overlapping part with the initial access downlink bandwidth part containing the RMSI CORESET; in the multiplexing mode 3, the SSB and the RMSI core are located at the same time, and there is no overlapping portion between the transmission bandwidth of the SSB and the initial access downlink bandwidth portion including the RMSI core.

Further, the subcarrier spacing combinations of SSB and RMSI CORESET include: { SSB SCS, RMSI CORESET SCS } - {15,15}, {15,30}, {30,15}, {30,30}, {120,60}, {120,120}, {240,60}, {240,120} }, where the unit of subcarrier spacing may be kHz.

In a Physical Broadcast Channel (PBCH), a multiplexing pattern of SSBs and RMSIs (CORESET and PDSCH), RMSI CORESET bandwidth, RMSI CORESET time-domain length, and frequency-domain offset (in units of Physical resource blocks) are jointly coded with 4 bits. According to the first 4 bits of the RMSI-PDCCH-config in the Master Information Block (MIB), the UE selects a certain time-frequency resource as the core set of the RMSI according to table 1({ SSB SCS, RMSI core SCS } - {120,60}) and table 2({ SSB SCS, RMSI core SCS } - {240,120 }). Wherein, the frequency domain offset in table 1 and table 2 is a frequency difference between the minimum RB number of the SSB defined by the subcarrier spacing of the RMSI CORESET and the minimum RB number of the RMSI CORESET.

Condition a indicates that Precoding Resource Block Group (PRG) used by SSB and RMSI CORESET are the same in size. Condition B indicates that Precoding Resource Block Group (PRG) sizes adopted by SSB and RMSI CORESET are different.

Wherein the SFN is_CAnd n_CRespectively representing a System Frame Number (SFN) and a time slot index occupied by RMSI CORESET; SFN_SSBAnd n_SSBRespectively representing the system frame number and the slot index occupied by the SSB.

For the SSB and RMSI CORESET multiplexing mode 2(pattern 2), as shown in table 3 and table 4, the RMSI CORESET time domain configuration table has only one configuration option, and the corresponding RMSI CORESET time domain length is 1OFDM symbol. However, as shown in table 1 and table 2, for { SSB, RMSI CORESET } subcarrier spacing of {120,60} kHz, the time domain length of RMSI CORESET corresponding to configuration index (index) ═ 10/11/14/15 is 2 OFDM symbols; for { SSB, RMSI CORESET } subcarrier spacing is {240,120} kHz, and the configured index is 6/7/10/11 corresponding to a RMSI CORESET time-domain length of 2 OFDM symbols. At this time, the RMSI CORESET corresponding to adjacent SSBs may overlap.

Fig. 3 shows a schematic flow chart of the method of signal detection of the present application.

301, the network device determines configuration information, where the configuration information is used to indicate a resource location of each control channel resource in a time window when the control channel resource and the common signal block are in a time division mode, and the time window includes at least two control channel resources, each of the at least two control channel resources corresponds to one common signal block, and time domain lengths of the at least two control channel resources are not all the same.

Specifically, the time division pattern may be pattern 2 as shown in fig. 2, and the configuration information is used to indicate resource positions of all control channel resources included in a time window, where the control channel resources in one time window have a one-to-one correspondence relationship with the common signal block resources. In this embodiment of the application, the time window at least includes two control channel resources, and the time domain lengths of the at least two control channel resources are not all the same, and may be at least two lengths, for example. The time window may be a period of time for mapping the control channel, for example, the time window may be one time unit, or may be multiple time units, and the time unit may be a frame, a half frame, a subframe, or a slot, and the like.

It should be noted that the subcarrier spacing of the common signal block and the subcarrier spacing of the control channel resource may be different, that is, the time length of the same time unit corresponding to the common signal block and the control channel resource is different, for example, as shown in fig. 4, the time length of two time units of the SSB is the same as the time length of one time unit of the RMSI.

Alternatively, the time division pattern may be pattern 1 shown in fig. 2.

It should be understood that, in the embodiment of the present application, the common signal block may be an SS/PBCH block, and the control channel resource may be an RMSI core, an OSI core, a control channel resource of a paging (paging) channel, a control channel resource of a random access response, and the like, which is not limited in the embodiment of the present application.

In the following examples, "RMSI CORESET" is used as an example for explanation

Optionally, in this embodiment, a control channel resource whose time domain length of the control channel resource is a first time domain length is referred to as a "first control channel resource", and a control channel resource whose time domain length of the control channel resource is a second time domain length is referred to as a "second control channel resource".

For example, the first time domain length is 2 OFDM symbols, and the second time domain length is 1OFDM symbol.

Alternatively, the time domain length of the common signal block may be a fixed value, for example, in the case of a subcarrier spacing of the common signal block, the time domain length of the common signal block is 4 OFDM symbols.

Alternatively, the number of first control channel resources included in the time window may be determined according to the time domain length of the time window and the number of common signal blocks included in the time window.

Specifically, the common signal blocks are in one-to-one correspondence with the control channel resources, such that the number of common signal blocks in a time window is the same as the number of control channel resources associated with the common signal blocks, and since the time domain length of the common signal blocks is usually fixed, the number of first control channel resources associated with the common signal blocks in the time window can be determined according to the time domain length of the time window and the number of common signal blocks included in the time window.

Optionally, when the first control channel resource exists in the control channel resource corresponding to the common signal block, the position of the first control channel resource may be predefined.

Alternatively, in the case that the system parameter of the control channel is 60kHz, for example, the system parameter may be subcarrier spacing (SCS), the time domain length of the first control channel resource is 2 OFDM symbols, and the time window includes 1 or 2 number of first control channel resources, wherein the time domain length of the time window is one time unit, the time unit includes 14 OFDM symbols, and the number of common signal blocks is 4.

Specifically, for a { SS/PBCH block, RMSI CORESET } subcarrier spacing of {120,60} kHz, a time window including 14 OFDM symbols, the number of common signal blocks being 4, and the time domain length occupied by each common signal block being 2 OFDM symbols in the case of the RMSI CORESET subcarrier spacing, the RMSI CORESET may optionally configure the remaining 6 OFDM symbols of the time domain position in the time window, as shown in fig. 4, and respectively correspond to an OFDM symbol index (index) ═ 0/1/6/7/12/13. Thus, within the time window (14 OFDM), at most 2 RMSI CORESET of time domain length 2 OFDM symbols are placed.

Optionally, when the first control channel resource exists in the control channel resource corresponding to the common signal block, the first control channel resource corresponds to the previous common signal block as much as possible. In other words, the time domain resources of the common signal block corresponding to the first control channel resources precede the time domain resources of the common signal block corresponding to the second control channel resources in the time window.

Optionally, the time domain resources of the common signal block corresponding to the first control channel resources in the time window may also follow the time domain resources of the common signal block corresponding to the second control channel resources.

Optionally, in a case that the time window includes 1 number of first control channel resources, a starting resource position of the first control channel resources is located at the 1 st OFDM symbol in the time window (14 OFDM symbols), that is, the first control channel resources occupy the 1 st OFDM symbol and the 2 nd OFDM symbol. The resource positions of the remaining second control channel resources may be any three positions among the 6 th OFDM symbol, the 7 th OFDM symbol, the 12 th OFDM symbol, and the 13 th OFDM symbol.
