Description

Access method and device

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an access method and an access device.

Background

The wireless communication system at least includes a network station (node) and User Equipment (User Equipment, UE for short) for downlink transmission and uplink reception, where the number of stations may be one or more. After the UE is started, a network station is searched and network access is carried out through the network station. If a plurality of network stations are included in one wireless network, the UE can be accessed through any one of the plurality of network stations.

For example, in a Long Term Evolution (LTE) system, each network station may be configured as a cell (cell), each cell sends a Synchronization (SYNC) signal, and the UE detects the SYNC signals of different cells and selects a cell for network access, which is called access.

Existing communication systems mainly focus on low-frequency band deployment, and network stations in the communication systems have fewer antennas. With the development of communication technology, communication systems are deployed in a large bandwidth range of 0.4 GHz-100 GHz in the future, and the number of antennas owned by network stations is increased dramatically to hundreds or even thousands. Conventional access schemes are not suitable for future communication systems, and therefore there is a need to provide an adaptive access scheme for future communication systems.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

In the embodiment of the present invention, the related devices include a sending network device and a receiving device, and downlink transmission and uplink reception may be performed between the sending device and the receiving device accessing the sending device. The sending device may send one or more access signals, and the receiving device may receive the one or more access signals sent by the sending device and may perform network access according to the received one or more access signals.

The sending device may be a base station or other types of transmission point devices, and the receiving device may be a user equipment (or terminal). Of course, the present invention is not limited to the above two devices, and for example, the sending device may also be a terminal capable of performing configuration operations on other terminals. A transmitting device may also be considered to comprise a plurality of network stations. The network station may include only radio frequency (e.g., RRU) or both baseband and radio frequency (e.g., Active antenna). The network station may include only a baseband (e.g., BBU); or it may not include any digital/radio frequency function of the air interface layer, only takes charge of high-level signal processing, and puts the baseband processing of the air interface layer to active antenna. Other various network implementation possibilities also exist.

The base station may be an LTE system or an evolved Node B (eNB or e-NodeB) in the LTE system, a macro base station, a micro base station (also referred to as a "small base station"), a pico base station, an Access Point (AP) or a transmission point (TRP), and may also be a base station in a future network, such as a base station in a 5G network.

A Terminal may also be referred to as a User Equipment (UE), or may be referred to as Terminal, a Mobile Station (MS), a Mobile Terminal (RAN), and the like, and the Terminal may communicate with one or more core networks via a Radio Access Network (RAN), for example, the Terminal may be a Mobile phone (or may be referred to as a "cellular" phone), a computer with a Mobile Terminal, and the like, and for example, the Terminal may also be a portable, pocket, handheld, computer-embedded, or vehicle-mounted Mobile device, and they exchange voice and/or data with the RAN. The terminal in the embodiment of the present invention may also be a D2D (Device to Device) terminal or an M2M (Machine to Machine) terminal.

For convenience of description, the following embodiments take TRP as a transmitting device and user equipment as a receiving device as an example for explanation.

The wireless network may cover a plurality of cells (cells), different cells cover different ranges, and one cell may be used for the user equipment to access the network. Each cell corresponds to a unique cell ID. One or several TRPs may be included in one cell. Each TRP includes N antennas, N being an integer greater than or equal to 1. The antennas on the TRP may perform beamforming, and the downlink signals are transmitted on the antennas after beamforming. Each beam provides either wide or narrow coverage, depending on the number of antennas and the beamforming approach.

In the embodiment of the present invention, a cell in a wireless network may be replaced with a System information area (System information area). A cell or system information area is defined as a wireless network object. In the following embodiments, unless otherwise specified, a "cell" is used for description, but it should be understood that a "cell" in the embodiments of the present invention may be replaced with a "wireless network object" defined above, such as a "system information area".

Fig. 1 schematically shows a network architecture to which an embodiment of the present invention is applicable. Wherein, cell 1 includes a TRP, the TRP sends a wide coverage beam to cover the range of the cell; one TRP is included in cell 2, which transmits two narrow coverage beams (beam 1 and beam2 shown in cell 2 in the figure) to cover the range of the cell; two TRPs are included in the cell 3, each TRP transmits one narrow coverage beam, and the two narrow coverage beams (beam 1 and beam2 shown in the cell 3 in the figure) transmitted by the two TRPs can cover the range of the cell.

The TRP in the wireless network sends an access signal, and the user equipment can perform network access based on the received access signal. In the embodiment of the present invention, an access signal for a user equipment to access a network is referred to as an as (access signal).

It should be noted that. The AS in the embodiment of the present invention is used to broadly refer to one or several signals that may be used by the user equipment during the process of accessing the network, and is a generic term for signals required by the user equipment during the process of accessing the network. The AS may comprise one signal or may comprise a plurality of signals. An AS may be used to implement one or more functions that may include, but are not limited to: initial synchronization (e.g., cell synchronization, time/frequency domain synchronization), cell (or system information region) ID detection, system information demodulation, and so on. Accordingly, signals contained within an AS may perform one or more of the functions enumerated above. In the embodiment of the present invention, the functions provided by the AS may include one or some of the above-listed functions, but are not limited to the above-listed functions, and signals included in one AS are also not limited to specific signals for implementing one or some of the above-listed functions.

In the embodiment of the invention, one AS can enable one or more user equipment to access a cell. A user equipment may also access a cell based on one or more ASs.

In some embodiments, an AS contains a component. In other embodiments, an AS includes multiple components (components). One component may be used to implement one function (such as time-frequency synchronization function) in the network access procedure, and different components may be used to implement different functions in the access procedure or applied to different stages or different steps in the access procedure. The component or components included in different ASs may be different, and the user equipment may distinguish different ASs based on the component or components in the ASs. For example, AS1 and AS2 are two different ASs transmitted by two TRPs in one cell (one TRP transmits one AS), AS1 and AS2 respectively include two components (component1 and component2), component1 of AS1 is the same AS component1 of AS2, and component2 of AS1 is different from component2 of AS 2. More specifically, component1 contains a cell ID, and component2 contains a TRP ID.

In the embodiment of the invention, the TRP in the cell can send one or more AS, and one user equipment can receive one or more AS sent by the cell in the downlink and can access the cell according to the received AS.

One AS can be transmitted by one TRP or a group of TRPs. From the perspective of one TRP in one cell, the TRP may transmit one AS, and the transmitted AS is different from the AS transmitted by other TRPs in the cell; or, the TRP may transmit one AS, and the transmitted AS is the same AS the AS transmitted by at least one other TRP in the cell; alternatively, the TRP may send multiple ASs.

Optionally, the AS may transmit at a center frequency point of the cell, or may transmit at other frequency points of the cell. For example, in some embodiments, the sending frequency point of the AS may be selected arbitrarily, that is, the AS may be sent at any frequency point in the system bandwidth; in other embodiments, the AS may transmit at any frequency point in a set of frequency points predetermined within the system bandwidth.

Alternatively, the number of ASs transmitted by one TRP in one cell at different time points may be kept constant, or the number of ASs transmitted at least two different time points may be different.

Alternatively, the number of ASs transmitted by a cell may be related to a number of factors. For example, the number of ases transmitted by a network station is related to the number of beams used by the network station, e.g., the number of ases transmitted by a network station is equal to the number of beams used by the network station. AS another example, the number of ASs transmitted by all network stations in a cell is related to the number of network stations in the cell, for example, the number of AS transmitted by a cell is the same AS the number of network stations included in the cell. AS another example, the number of ASs transmitted by all network stations in a cell is related to the number of network stations in the cell and the number of beams used by each network station.

Optionally, when a plurality of TRPs are included in one cell, the number of ASs transmitted by each TRP is different from each other; alternatively, the number of ases transmitted by at least two TRPs is the same AS each other.

AS an example, if a cell includes N (N is an integer greater than 1) TRPs and each TRP transmits one AS, the cell may transmit N ASs. Each TRP adopts a wide beam forming mode to transmit AS, and the transmitted AS provides wide coverage for the TRP, namely a beam used by the TRP can cover the coverage range of the TRP. Thus, the N ASs of the cell can cover the coverage of all TRPs of the entire cell.

AS another example, a cell contains a TRP, which transmits M ASs using M (M is an integer greater than 1) beams, each AS transmitting using one beam, each beam pointing in one direction, and the M beams may cover the coverage area of the entire cell.

If one TRP in one cell or cell transmits multiple ASs, different ASs transmit on different resources, i.e., the multiple ASs may be multiplexed in one or more multiplexing manners. The multiple ASs are multiplexed in different ways, so that the user equipment can distinguish different ASs.

The multiplexing modes adopted by different ASs may include one or more combinations of the following multiplexing modes:

time Division Multiplexing (TDM): different ases or at least one component of different ases, transmitting at different time resources;

frequency Division Multiplexing (FDM): different ases or at least one component of different ases, transmitting at different frequency resources;

space Division Multiplexing (SDM): different ases or at least one component of different ases, transmitting using different beams or through different TRPs in different spatial resources;

code Division Multiplexing (CDM): different ases, or at least a component of different ases, are transmitted using different sequences, where the sequences may include one or more combinations of transmission sequences (e.g., base sequence), scrambling sequence (scrambling sequence), and spreading sequence, among others.

In one example where multiple ases are multiplexed using CDM, different ases are generated using different base sequences, such that the sequences of the different ases are different from each other, thereby implementing CDM multiplexing of the multiple ases. For example, the first AS employs a first base sequence, and the second AS signal employs a second base sequence.

In other examples where multiple ases are multiplexed using CDM, a method of combining CDM with other multiplexing schemes may be used. For example, in an example where CDM is used in combination with SDM, a first AS transmits from a first TRP and a second AS transmits from a second TRP, the first base sequence may correspond to an ID of the first TRP and the second base sequence may correspond to an ID of the second TRP. For another example, if a first AS transmits from a first shaped beam and a second AS transmits from a second shaped beam, a first base sequence may correspond to the ID of the first shaped beam and a second base sequence may correspond to the ID of the second shaped beam. AS another example, the first AS and the second AS use the same base sequence but use different scrambling sequences (scrambling sequences) for scrambling (scrambling).

Fig. 2a shows an example of multiplexing of multiple ASs with FDM. AS shown in fig. 2a, a cell includes 4 TRPs (TRP 1 to TRP4 shown in the figure), each TRP transmits an independent AS on different frequency points, and the frequency point position used by each TRP for transmitting an AS is shown in a square in a time-frequency resource table in the figure, where a square marked with TRP1 represents the frequency resource position used by TRP1 for transmitting an AS, a square marked with TRP2 represents the frequency resource position used by TRP2 for transmitting an AS, and so on. The UE can distinguish different TRPs according to the frequency points occupied by the AS.

In other examples, multiple TRPs (two or more TRPs) may transmit the same AS on the same time-frequency resource, in which case the UE cannot distinguish between the TRPs.

Fig. 2b shows an example of multiplexing of multiple ASs with FDM and SDM. AS shown in fig. 2b, one cell contains 1 TRP, and a plurality of antennas on the TRP transmit 3 ASs by beamforming, each beam pointing in one direction. The frequency resource locations occupied by each AS are shown AS squares in the adapted resource table in the figure, where the square identified with beam1 represents the frequency resource location occupied by AS1 transmitted using beam1, the square identified with beam2 represents the frequency resource location occupied by AS2 transmitted using beam2, and so on. The UEs distributed in different directions in the cell search beams in the corresponding directions to receive the strongest or sufficiently strong AS and access the cell according to the searched AS.

Figure 3a shows an example of multiplexing of multiple ASs using TDM. AS shown in fig. 3a, one cell includes 3 TRPs, each TRP transmits an independent AS at the same frequency point and different time points, and the time frequency resource location used by each TRP to transmit an AS is shown in a square in the time frequency resource table in the figure, where the square identified with TRP1 represents the time frequency resource location used by TRP1 to transmit an AS, the square identified with TRP2 represents the time frequency resource location used by TRP2 to transmit an AS, and so on.

One AS may comprise two components: MIB and SYNC. The MIB carries system information, and SYNC is a synchronization sequence.

Fig. 3b shows an example of multiplexing of multiple ASs using TDM and SDM. AS shown in fig. 3b, one cell contains 1 TRP, and multiple antennas on the TRP transmit 3 ASs by beamforming, each beam pointing in one direction. The frequency resource locations occupied by each AS are shown AS squares in the adapted resource table in the figure, where the square identified with beam1 represents the frequency resource location occupied by AS1 transmitted using beam1, the square identified with beam2 represents the frequency resource location occupied by AS2 transmitted using beam2, and so on. The UEs distributed in different directions in the cell search beams in the corresponding directions to receive the strongest or sufficiently strong AS and access the cell according to the searched AS.

AS described above, one AS may include one component (component) or a plurality of components. If each of a plurality of ases transmitted by a cell includes multiple components, one or more of the components of the plurality of ases may be multiplexed using one or more multiplexing schemes (the multiplexing scheme that may be used may include one or more of FDM, TDM, CDM, and SDM). The user equipment may distinguish between different ases by some component in the AS.

Fig. 4 shows an example in which one AS includes a plurality of components, and a certain component of the plurality of AS is multiplexed by FDM. AS shown in fig. 4, the two ASs are respectively composed of two parts, the first part and the second part are transmitted at different times, the first parts of the two ASs are completely the same, the second parts of the two ASs are multiplexed on different frequency resources, and the multiplexing of the two ASs is realized by multiplexing the second parts.

One AS can satisfy all the conditions required by all the user equipments in the cell to access the cell, and one AS can also satisfy some of the conditions required by all the user equipments in the cell to access the cell. In the latter case, the AS is functionally enabled to enable the ue to access the cell via the AS on the premise that the received signal strength of the AS received by the ue satisfies the performance requirement of the access cell (for example, the received signal strength of the AS is higher than the set threshold).

One user equipment does not necessarily access the cell according to each AS, but in case the received signal strength of the user equipment receiving the AS is sufficiently large, the operation of the access cell may be implemented by one or several of the ASs.

The user equipment may use a number of possible baseband algorithms for cell access based on one AS or several ASs. The following exemplarily shows several possible baseband algorithms:

algorithm 1: the user equipment independently detects an AS. After the user equipment searches an AS, the cell access is carried out according to the AS, if the cell is successfully accessed, the access process is finished, the user equipment does not process other AS, otherwise, the next AS is searched, and the process is repeated.

And 2, algorithm: the user equipment jointly detects a plurality of ASs. After searching an AS, the user equipment combines the AS and the previously received AS to carry out cell access, if the cell is successfully accessed, the access process is finished, otherwise, the user equipment searches the next AS and repeats the process.

Algorithm 3: after receiving multiple ASs, the user equipment selects one AS according to the signal quality (for example, selects the AS with the maximum received signal strength), and performs network access according to the selected AS. In specific implementation, after the user equipment detects one AS, other ASs are detected according to the time-frequency position relationship between the ASs preset by the system, the AS with the highest quality is selected from all the detected ASs, and then the cell access process is carried out according to the selected AS.

And algorithm 4: after receiving multiple ASs, the user equipment combines the multiple ASs and performs network access according to the combined AS. In specific implementation, after the user equipment detects one AS, other ASs are detected according to the time-frequency position relationship between the ASs preset by the system, all the detected ASs are combined, and then the cell access process is carried out according to the combined AS.

It should be noted that, the above algorithms 3 and 4 only exemplarily show the manner of processing multiple received ASs (selecting an AS or performing combining processing according to signal quality), and the embodiments of the present invention are not limited to the above signal processing manners.

From the above description, fig. 5 and 6 exemplarily show AS transmission flows on the transmitting device side and the receiving device side, respectively.

As shown in fig. 5, the flow implemented by the sending device side may include the following steps:

step 501: the number of ASs that need to be transmitted by a cell is determined. In this example, the determined number of ASs is plural.

The number of AS transmitted by one cell or one TRP may be referred to the description of the foregoing embodiments, and will not be described in detail herein.

Step 502: and determining the multiplexing mode of the AS. The multiplexing method is as described above and will not be described in detail here.

Step 503: and transmitting the determined corresponding quantity of AS in downlink according to the determined multiplexing mode.

As shown in fig. 6, the flow implemented by the receiving device (e.g. user equipment) side may include the following steps:

step 601: the user equipment receives one or more ASs transmitted by network stations in the cell. The method for sending the AS can adopt the method for sending the AS provided by the embodiment of the invention.

Step 602: and the user equipment performs network access according to the received AS.

Further, in some embodiments, after the user equipment accesses the network, the following process may be further included: the transmission related information is obtained from the AS on which the network is accessed. In other embodiments, after the ue accesses the network, the following process may be further included: and acquiring the transmission related information corresponding to the characteristic of the AS according to which the network is accessed according to the characteristic of the AS according to which the network is accessed and the corresponding relation between the characteristic of the AS and the transmission related information. Wherein the transmission related information may include a channel bandwidth and/or start position information. The characteristics of the AS may include: sequences used by the AS (such AS basic codeword sequences, scrambling code sequences, etc.) or frequency points occupied by the AS, etc., are not listed here.

For example, after the user equipment successfully accesses the cell according to the received AS, the channel bandwidth and the start position information may be further obtained. This information may be obtained by detecting additional signals, such AS by detecting system information (system information), or may be obtained indirectly or directly from the AS.

In an example of directly obtaining the channel bandwidth and the start position information according to the AS, the AS includes the channel bandwidth and the start position information (e.g., includes bits for indicating the channel bandwidth and the start position), so that the channel bandwidth and the start position can be directly obtained according to the AS.

In an example of indirectly obtaining the channel bandwidth and the start position information according to the AS, a scrambling sequence (scrambling sequence) of the AS has a corresponding relationship with the channel bandwidth and the start position, for example, the channel bandwidth has 4 possible values, the scrambling sequence of the AS has 4 possible sequences, and the user equipment can obtain the corresponding channel bandwidth according to the corresponding relationship after detecting the scrambling sequence of the AS.

Based on the flow shown in fig. 6, fig. 7 shows a more specific signal receiving flow implemented by the user equipment side.

As shown in fig. 7, the process may include the following steps:

step 701: the user equipment searches the AS;

step 702: after the user equipment searches the AS, network access is carried out according to the searched AS;

step 703: the user equipment determines whether the cell is successfully accessed, if so, the step 704 is carried out, otherwise, the step 701 is carried out to continue searching for the AS;

step 704: the access procedure of the user equipment is completed.

Optionally, after the user equipment searches for the AS again, the user equipment may independently use the searched AS for network access, or may combine the searched AS with the previously searched AS for network access.

According to the process shown in fig. 7, AS an example, after the user equipment searches for a first AS, network access is performed according to the first AS, if the cell is successfully accessed, the process is ended, otherwise, the user equipment searches for a second AS; after searching the second AS, the user equipment jointly uses the first AS and the second AS which are searched to carry out network access, if the cell is successfully accessed, the process is ended, otherwise, the user equipment searches a third AS. The subsequent processes can be analogized until the cell is successfully accessed or the ending condition is met.

In the embodiment of the invention, one AS can enable one or more user equipment to access the network, so after the user equipment searches the AS, the user equipment can access the network according to the searched AS in general, but some special cases are not excluded, the AS cannot be searched, or the access can be failed even if the AS is searched. For these situations, an end condition for terminating the network access may be set, and when the end condition is satisfied, the ue may end the network access procedure and may further prompt that the network access fails. For example, a default duration or a default number of times may be set, and when the network has not been successfully accessed within the default duration or when the access number reaches the default number of times, the end condition is satisfied.

As can be seen from the above description, in the above embodiments of the present invention, one sending device sends one or more access signals for network access by a receiving device, and different access signals are transmitted on different resources, and specifically, are multiplexed in one or more multiplexing manners. It can be seen that one transmitting device may transmit one access signal or a plurality of access signals, thereby improving flexibility of system access, and further applying the embodiment of the present invention to a communication system deploying frequency resources in a large bandwidth range and using a larger number of antennas in the future.

Based on the same technical concept, the embodiment of the present invention further provides a sending device, which can implement the AS sending procedure described in the foregoing embodiment.
