Method, device and system for accessing site

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, and a system for accessing a station.

Background

With the development of mobile communication systems, the transmission rate and the service quality that can be provided by the communication system are higher and higher, and the user service also puts higher and higher requirements on the transmission rate of the communication system. Third generation partnership project (3)^rdGeneration Partnership Project, 3 GPP) introduced a Carrier Aggregation (CA) technique, so that the transmission rate of a terminal (UE) is guaranteed without greatly increasing the system bandwidth, and a higher throughput is provided for the UE. The simultaneous deployment of the small cell and the macro network is one of important scenarios, and in such a scenario, the small cell and the macro network may provide services for the UE together.

In the prior art, when a UE accesses a site, a Preamble (Preamble) needs to be sent to a base station, if the Preamble can be correctly received by the base station, the base station sends a Response message (e.g., RA-Response random access Response message) to the UE, the UE sends a message (scheduling transmission message) to the base station after receiving the Response message, and the base station sends a message (feedback contention resolution message) to the terminal after sending the Response message to the terminal.

In the above prior art, the random access process requires multiple interactions between the base station and the terminal, so that in the handover process or the access process in the prior art, the conventional access process of accessing the UE to the station has a certain time delay.

Detailed Description

The method for accessing the site in the embodiment of the invention is directed to a scene that a control plane and a user plane of a terminal (UE) are separated, and the user plane and the control plane can be independently and respectively switched to different base stations in the scene. For example:

in scenario 1, the control plane of the UE remains at the second site, and the user plane transmission of the UE is handed over from the third site to the first site.

The second station is, for example, a macro base station eNB, the third station is, for example, Pico2, and the first station is, for example, Pico 1.

In this scenario, TA variation is not considered here because the small base station coverage is relatively small. The terminal does not need to perform a complete access procedure.

In scenario 2, the control plane and the user plane of the UE are in the first site and the second site, respectively, and the user plane of the terminal is switched to the first site.

The first station is a Macro base station Macro eNB1, and the second station is Pico 1.

In addition, because the target site of the user plane switching is the base station serving the terminal, the terminal does not need to perform a complete access process.

Scenario 3, the user plane and the control plane of the UE are in the second site, and the user plane of the terminal is switched to the first site.

The second station is a Macro base station Macro eNB1, and the first station is Pico 1.

In scenario 4, the user plane and the control plane of the UE are in the first site and the second site, respectively, and the control plane of the UE is to be handed over to the first site.

The first station is Pico, the second station is Macro network eNB, that is, Macro eNB, and the first station is Pico.

The above description is only for convenience of description and illustrative purposes of the implementation of the technical solution of the present invention, and does not limit the technical solution described in the present invention.

Referring to fig. 1, an embodiment of a method for accessing a station according to an embodiment of the present invention includes:

101. receiving a first message sent by a second station, wherein the first message comprises first configuration information;

the UE receives a first message sent by a second station, where the first message includes first configuration information, and the first configuration information includes configuration information of a Scheduling Request (SR), or configuration information of a Sounding Reference Signal (SRs), or configuration information for sending data.

The configuration information for transmitting data in the present embodiment is configuration information of data to be transmitted when the UE is to communicate with the second station.

The first site is a target base station accessed by the UE, and the second site is a base station currently accessed by the UE.

102. And sending the first access information to the first station according to the first configuration information so as to access the first station for communication.

The first access information is the SR or the SRs or the ACK or the NACK or data. The data are various communication data sent by the terminal to the first station so as to access the first station for communication.

In this embodiment, the UE sends the first access information to the first station to access the first station for communication, that is, the UE may send the SR or SRs, or ACK, or NACK, or data to the first station to access the first station for communication. For acknowledgement (acknowledgement) and Non-acknowledgement (Non-acknowledgement), specifically, in the prior art HARQ (hybrid Automatic Repeat Request) or ARQ (Automatic Repeat Request) mechanism, the sender sends a data packet, and feeds back ACK if the receiver receives correctly, and feeds back NACK if the receiver does not receive correctly. The sender receiving the NACK retransmits the data packet. In the present invention, ACK or NACK is not feedback for HARQ or ARQ transmission, but an indication signal may be considered as a special SR or a first SR of the terminal and the first station. Here, the ACK/ACK is used as an indication signal for indicating that the terminal directly accesses the first station or for indicating that the terminal does not need to perform a conventional random access procedure but directly accesses the first station by transmitting ACK/NACK, and starts communication with the first station.

In the embodiment of the invention, the UE receives a first message sent by a second site, wherein the first message comprises first configuration information, and the first access information is sent to the first site to access the first site for communication according to the first configuration information, so that the UE can access the first site for communication according to the SR or SRS or ACK or NACK or data without first executing random access, namely, the UE needs to first request resources from a target base station, therefore, the access speed of the UE and the target base station is increased, the signaling interaction process between the UE and the target base station is reduced, and the time delay of accessing the target base station is reduced.

Referring to fig. 2, an embodiment of a method for accessing a station according to an embodiment of the present invention includes:

201. receiving a first message sent by a second station, wherein the first message comprises first configuration information;

and the UE receives a first message sent by a second site, wherein the first message comprises the first configuration information, and the first configuration information comprises SR configuration information, SRS configuration information or configuration information for sending data. The configuration information for transmitting data in the present embodiment is configuration information of data to be transmitted when the UE is to communicate with the second station.

In this embodiment, the sending of the first access information to the first station to access the first station for communication specifically includes: the UE does not initiate random access to the first station, but directly sends the first access information to the first station to access the first station, that is, the UE sends the first access information to the first station instead of performing random access to access the first station.

Specifically, for example, if the first access information is NACK, if the first station receives NACK on the SR transmission resource, and before receiving the NACK, the station has not allocated feedback ACK/NACK resources to the terminal, or the station and the terminal have no Hybrid Automatic Repeat Request (HARQ) or Automatic Repeat Request (ARQ) transmission, or the station has not communicated with the terminal, when it considers that the NACK is an indication signal or a special SR for indicating that the terminal directly accesses the first station, and for indicating that the terminal does not need to perform a conventional random access procedure but directly accesses the first station by transmitting the NACK, and starts to communicate with the first station.

The UE specifically sends a signal on the resource for sending the SR, for example, sends the SR or ACK or NACK, and the embodiment of the present invention is not limited in particular. It should be understood that the embodiment of the present invention is only a specific implementation example, but the content of the technical solution of the present invention is not limited to the specific example.

Taking the first access information as SR as an example: the UE sends an SR to the first station, which is represented by modulated symbols d (0) =1 (this modulation scheme is also referred to as pucchfmat 1). The UE transmits the SR by modulating using a simple Amplitude Shift Keying (ASK) modulation scheme. The UE transmits an SR, which is represented as a modulation symbol d (0) = 1. Of course, if the UE does not wish to transmit an SR (e.g., the UE does not wish to request bandwidth, does not wish to be scheduled by the base station, or does not wish to have direct access to the first site in the context of the present invention), the UE does not transmit any signal on the resource that transmits the SR. (The SR users On-Off keying (ASK) modulation), with The transmission a SR with modulation system d (0) =1to request a PUSCH resource (positive transmission), and transmission with a not yet transmitted data not request scheduled (negative SR) — then The first station receives a signal On The resource On which The UE transmits The SR, or receives signal d (0) =1, then when it considers that an indication signal or a special SR is received, it is intended to indicate that The terminal has direct access to The first station, which is intended to indicate that The terminal does not need to perform a conventional random access procedure but can access The first station directly by transmitting The signal to start and The first communication station.

Taking the first access information NACK as an example: the UE transmits ACK or NACK by modulating with Binary Phase Shift Keying (BPSK), which may also be referred to as PUCCH format1a, where the modulated symbols are ACK = d (0) =1 and NACK = d (0) = -1. d (0) is a complex-value symbol.

If the first station receives NACK = d (0) — 1 on the SR transmission resource, that is, knows that NACK is received, and before receiving the NACK, the station has not allocated feedback ACK/NACK resources to the terminal, or the station and the terminal have no HARQ or ARQ transmission, or the station has not communicated with the terminal, when it considers that the NACK is an indication signal or a special SR for indicating that the terminal has direct access to the first station, for indicating that the terminal does not need to perform a conventional random access procedure but can directly access to the first station by transmitting the NACK, and starts communicating with the first station. Likewise, ACKs may be implemented as such.

Of course, on the SR resource, the UE uses Quadrature Phase Shift Keying (QPSK) modulation (this modulation scheme may also be referred to as PUCCH format1 b), where modulation symbol (d (0) is equal to 1, -j, j or-1. One of the values is selected as first access information to be transmitted on the resource for transmitting the SR, and then the first access information may be regarded as a special SR, also referred to as an SR for the terminal to communicate with the first station, and is used to indicate that the terminal directly accesses to the first station, and to indicate that the terminal does not need to perform a conventional random access procedure but can directly access to the first station by transmitting the NACK, and starts to communicate with the first station.

In summary, the terminal transmits a signal on the resource on which the SR is transmitted, which may be an SR, or an ACK or NACK, or other signal or symbol, which we shall also refer to as SR here, which is a special SR, which is the first SR that the terminal communicates with the first station. Which indicates that the terminal directly accesses the first station, and that the terminal directly accesses the first station by transmitting the NACK without performing a conventional random access procedure, and starts communication with the first station.

The first message may further include second configuration information, where the second configuration information is a value of timing advance (abbreviated as TA) of the UE and the first station, and TA =0 in this embodiment.

The first message may further include first indication information.

The second configuration information or the first indication information is used for indicating the terminal not to initiate random access to the first station, or indicating the terminal not to initiate random access to the first station, and directly sending the first access information to access the first station; or, the first access information is used for instructing the terminal to directly send the first access information to access the first site; or, the apparatus may be configured to instruct to transmit the first access information instead of performing random access to access the first station.

In this embodiment, the first configuration information, the second configuration information, and the first indication information are all sent by the first station to the second station.

Sending first access information to the first station to access the first station for communication, which may specifically be:

the UE sends ACK/NACK to the first site on the resource block which sends the SR according to the configuration information of the SR, so as to access the first site for communication;

or,

and the UE sends ACK/NACK to the first site on the resource block for sending the SR according to the configuration information of the SR, so that the first site obtains the SR according to the ACK/NACK.

And the UE sends ACK/NACK to the first station on the resource block for sending the SR, and the UE communicates with the first station for the first time.

In this embodiment, after receiving the first message, the UE may directly communicate with the first station according to the first message.

Specifically, the UE obtains configuration information of transmission data included in the first message, where the configuration information of the transmission data is scheduling resource information allocated by the first station, receives or transmits data to the first station on the allocated scheduling resource, and directly communicates with the first station according to the first message.

Wherein the first message further comprises indication information.

The indication information may be used to indicate: user plane handover of the UE, or Data Radio Bearer (DRB) handover, or user plane bearer handover, or user plane handover from the second station to the first station, or user plane data transmission from the second station to the first station, or user data transmission from the third station to the first station, or user plane establishment on the first station, or bearer/DRB/user plane bearer establishment on the first station, or cell addition for user data transmission, where the cell is a cell of the first station.

The indication information may also be used to indicate: control plane switching of the UE; or, Signaling Radio Bearer (SRB) handover; or, the control plane is switched from the second site to the first site; or, the transmission of control plane data is switched from the second site to the first site; or, the transmission of control signaling is switched from the second station to the first station; alternatively, the transmission of control signalling and the transmission of part of the user data is handed over from the second station to the first station.

In the process of instructing the user plane and/or the handover plane of the UE to perform handover, 1 bit of indication information may be used to identify whether the user plane or the control plane needs to be handed over, for example, if the value of the indication information is 1, the user plane of the UE is handed over, and if the value of the indication information is 0, the control plane of the UE is handed over.

Further, the first message further comprises at least one of:

the indication information of the first station, the cell indication information of the first station, the carrier information of the cell of the first station, and the scheduling resource information allocated by the first station.

By means of this message scheduling resource information in cell 1 of the first station is obtained, so that data can be received or transmitted on the scheduling resources to the first station. The terminal thus starts to listen to the data transmission from the cell under the first site to itself, receive the data sent by the first site or start sending data to the first site.

Specifically, the information of the handover may also be identified using 1 bit of indication information:

for example, if the user plane of the UE is switched, the first station sends a first message to the target user plane station, where the first message includes: 1-bit indication information (the value of the indication information is 1), and a station identifier/cell identifier of a control panel of the UE after handover;

the control plane switching and the user plane switching of the UE are switched to different sites/cells, the first site sends a first message to a target user plane site, and the first message specifically comprises: the indication information with 1 bit (the value of the indication information is 1), and the station identifier/cell identifier of the control plane station of the UE after handover, which may also include the identifier of the source user plane station.

And switching the control plane of the UE, wherein the first station sends a first message to a target control plane station, and the first message specifically comprises: 1-bit indication information (the value of the indication information is 0), and station marking/cell marking of a user plane station of the UE after switching;

the control plane switching and the user plane switching of the UE are switched to different sites/cells, the first site sends a first message to a target control plane site, and the first message specifically comprises: the indication information with 1 bit (the value of the indication information is 0), the station identifier/cell identifier of the user plane station of the UE after the handover, and may also include the identifier of the source control plane station.

The first message further comprises: and maintaining the configuration information or the configuration indication information of the user plane base station during the switching of the control plane, or maintaining the configuration information or the configuration indication information of the user plane base station during the switching of the user plane.

Wherein the configuration information of the SR comprises at least one of the following:

the time-frequency resource information of the SR, a configuration index (SR configuration index, which may also be referred to as SR-configuration index) of the SR, and a Physical Uplink Control Channel (PUCCH) resource block index (SR PUCCH resource index, which may also be referred to as SR-PUCCH-resource index) of the SR.

The terminal can calculate which subframes the terminal transmits the SR on through the configuration index of the SR, and the terminal obtains resource block information for transmitting the SR on one subframe through a physical uplink control channel resource block index (SR PUCCH resource index) of the SR. The terminal may obtain on which resource block of which subframes the SR is transmitted through a configuration index of the SR and a physical uplink control channel resource block index (SR PUCCH resource index) of the SR.

Specifically, through a configuration index (SR configuration index) of the SR in the message, the terminal may obtain an SR transmission period (SR transmission periodicity SR) through the following table_PERIODICITY) And SR subframe offset (SR subframe offset N)_OFFSET，SR) With the two parameters, the SR transmission time may be calculated as an uplink subframe (SR transmission resources the uplink frames utilization) satisfying the following formula:where nf is the system frame number (system frame number) and ns is the number of a symbol in a radio frame (slotted with radio frame).

The subframe information for transmitting the SR can thus be obtained by the above-described configuration index (SR configuration index) of the SR. There are of course other ways to obtain the subframe information for transmitting the SR. And is not limited herein.

TABLE 1 SR period and subframe offset configuration Table (UE-specific SR period and subframe offset configuration) for UE

In this embodiment, the SRS configuration information includes:

the SRS configuration information may specifically be content in an SRS uplink configuration information unit (sounding rs-UL-configuration information Element), or may also be time-frequency resource information of the SRS. Or, the SRS uplink configuration information Element (sounding rs-UL-configuration information Element) or the SRS time-frequency resource information may include at least one of the following information, that is, the SRS configuration information may be at least one of the following information: SRS Bandwidth (SRS-Bandwidth), SRS Bandwidth configuration (SRS-Bandwidth hconfig), frequency hopping Bandwidth (SRS-hoppingbandwidth SRS), frequency domain position (freqDomainPosition), SRS configuration index (SRS-ConfigIndex), cycle shift (cyclic shift), subframe configuration (SRS-subframe configuration SRS), Duration (Duration), length of period for transmitting SRS (Duration for periodic sounding signaling) SRS antenna port (SRS-antenna port) for indicating the number of antenna ports (antennas of the number of antenna ports used for transmitting the SRS). Of course, the above description only illustrates the content of the SRS uplink configuration Information Element (soundgrs-UL-configuration Information Element), and the content of the SRS uplink configuration Information Element (soundgrs-UL-configuration Information Element) is not limited to the above description.

The invention uses SRS time frequency resource information or RS uplink configuration information unit (sounding RS-UL-configuration information Element) to exemplify the SRS configuration information. However, the time-frequency resource information/SRS uplink configuration information Element (SoundingRS-UL-ConfigInformation Element) of the SRS may specifically include at least one of the following: SRS Bandwidth (SRS-Bandwidth), SRS Bandwidth configuration (SRS-Bandwidth hconfig), frequency hopping Bandwidth (SRS-HoppingBandwidth SRS), frequency domain position (freqDomainPosition), SRS configuration index (SRS-ConfigIndex), cycle change (cycloshift), subframe configuration (SRS-subframe configuration SRS), duration (duration), SRS antenna port (SRS-antenna port), and the like. Therefore, the present invention is not described repeatedly.

The configuration information may also be a configuration of the UE when adding a secondary cell, and specifically may include at least one of the following:

configuration information of a media access control MAC layer, configuration information of a packet data convergence protocol PDCP layer, configuration information of a radio link control protocol RLC layer, configuration information of a physical layer PHY, configuration information of a data radio bearer DRB(s), configuration information of a logic channel, and a packet data convergence protocol sequence number PDCP SN.

It should be noted that, before step 201, that is, before the UE receives the first message sent by the second station, the second station sends a request message to the first station, where the request message is used to request the UE to access the first station, and the first station sends a message for confirming access to the second station, where the message for confirming access includes configuration information of first access information, the second station sends the first message to the UE according to the message for confirming access sent by the first station, and the UE receives the first message, and the first message includes the configuration information of the first access information sent by the first station.

202. The UE communicates with a first station;

the UE communicates with the first station, may activate communication with the first station, or may communicate with the first station directly.

The specific communication mode may be one of the following modes;

and (I) the UE directly communicates with the first station according to the first message sent by the second station, or sends the first access information to the first station, wherein the first access information is used for requesting or activating communication with the first station.

In all the aspects of the present invention, the first access information is used for requesting or activating communication with the first station, and it is equivalent to the first access information being used for accessing communication with the first station.

Since the UE can obtain downlink synchronization with the first station in the measurement phase, and meanwhile, considering that the coverage area of the first station is small when the first station is a small cell, and considering that the TA change is not considered, the first station can be synchronized with the UE uplink. Therefore, the UE may directly start communicating with the first station, or the UE may send information to the first station, start communicating with the first station, or activate the UE terminal to start communicating with the first station.

Specifically, after receiving a first message sent by the second station, the UE completes configuration according to content included in the first message, and starts communication with the first station.

(II) the UE receives an activation message sent by the first site, directly communicates with the first site or sends first access information to the first site according to the received activation message, and the first access information is used for requesting or activating communication with the first site.

Specifically, the activation message may be that the first station sends a MAC layer message, for example, a MAC CE, to instruct the terminal to communicate with the first station, and then the UE starts to communicate with the first station. The activation message may be in the form of an RRC message, signaling of the physical layer, and the like, and is not limited herein.

And (III) the UE receives the activation message transmitted by the first site and forwarded by the second site, and directly communicates with the first site or transmits first access information to the first site according to the received activation message, wherein the first access information is used for requesting or activating communication with the first site.

Specifically, the activation message may be that the first station sends a MAC layer message, for example, a MAC CE, to instruct the terminal to communicate with the first station, and then the UE starts to communicate with the first station.

(IV) the UE receives the activation message sent by the second site, directly communicates with the first site or sends first access information to the first site according to the received activation message, wherein the first access information is used for requesting or activating communication with the first site;

and (V) the UE sends an RRC connection reconfiguration completion message/switching completion message to the first site according to the received bandwidth information or time-frequency resource information contained in the first message sent by the second site so as to access the first site. That is, the first message may include time-frequency resource information of an RRC connection reconfiguration complete message/handover complete message sent by the first station, and the UE sends the RRC connection reconfiguration complete message/handover complete message on the time-frequency resource to access the first station.

It should be noted that before step 202, that is, before the UE activates communication with the first station, an acknowledgement message may be sent to the second station, where the acknowledgement message may be used to notify the second station that the UE has completed configuration according to the first message or activate the terminal to communicate with the first station.

203. According to the first configuration information, sending the first access information to the first station so as to access the first station for communication;

the first access information is the SR or the SRs or the ACK or the NACK or data. The data are various communication data sent by the terminal to the first station so as to access the first station for communication. The SRS is a UE-specifically configured SRS.

If the first access information is SR, the specific access process is that the UE obtains subframe information for sending the SR according to an SR configuration index (english: SR-ConfigIndex) of the configuration information of the first access information, and can calculate, according to the SR configuration index, which subframes the UE sends the SR on.

The configuration information of the first access information may further include a physical uplink control channel resource block index (SRPUCCH resource index) of the SR, where the physical uplink control channel resource block index (SR PUCCH resource index) of the SR is used to provide PUCCH resource block information for the terminal to transmit the SR, that is, on which PUCCH resource block the UE can transmit the SR.

According to the configuration index (SR configuration index) of the SR and the physical uplink control channel resource block index (SR PUCCH resource index) of the SR, the terminal may obtain which PUCCH resource blocks on which subframes the SR is transmitted.

Further, the SR transmission mode can be optimized as an ACK/NACK transmission mode: and sending an ACK/NACK (English: Acknowledgement/Negative-Acknowledgement) message on the PUCCH resource block which sends the SR, so that the first site obtains the SR, wherein the SR is used for activating communication with the first site, and the SR is the first SR sent to the first site.

The UE transmits ACK/NACK on the resource block that transmitted the SR so that the base station receives the ACK/NACK on the resource block that transmitted the SR, then the base station knows that the terminal is to activate communication with the base station. Since the terminal has not previously communicated with the base station and there is no HARQ/ARQ related communication, the terminal should not feed back ACK/NACK to the base station according to the prior art, which should be transmitting SR according to the prior art. Therefore, the base station receives ACK/NACK on the resource block transmitting SR, which is regarded as a special mode, and the terminal communicates with the base station for the first time and requests the access station to communicate with the base station.

The UE receives ACK/NACK on the PUCCH resource block transmitting the SR, for example, it may be assumed that the UE all transmits ACK, and the first station considers that the SR is obtained for activating communication with the terminal, where the SR is the first SR transmitted by the terminal. Or the first station considers the ACK received thereby for activating communication with the terminal. Of course, we can also default that the UE sending NACK on the PUCCH resource block sending the SR represents the communication for activating the terminal and the first station. In short, because the terminal has not communicated with the base station before, there is not any HARQ/ARQ related communication at all, so according to the prior art, the terminal does not feed back ACK/NACK to the base station, and thus the base station receives ACK/NACK on the PUCCH resource block transmitting the SR, and knows that the terminal wants to access the base station for communication.

The configuration information of the first access information may further include the maximum transmission number of the terminal transmitting the SR: SRdsr-TransMax.
