Description

Method for transmitting and receiving messages, base station and user equipment

Technical field

The embodiments of the present invention relate to the field of communications, and in particular, to a method for sending and receiving a message, a base station, and a user equipment.

Background technique

In the existing communication system, the user equipment first receives the control channel, determines the transport block size (TBS, Transport Block Size) carried by the data channel scheduled by the control channel according to the control information in the received control channel, and determines the transport block. After receiving the data, it starts to receive data. For example, in a Long Term Evolution (LTE) system, the control channel may be a Physical Downlink Control Channel (PDCCH), or an Enhanced Physical Downlink Control Channel (EPDCCH), or other Control channel. The data channel may be a Physical Downlink Shared Channel (PDSCH).

In an existing LTE system, in a random access procedure, a user equipment first sends a random access preamble and then receives a random access response message. The base station includes one or more random access responses (RARs) in the random access response message to the user equipment. The random access response is associated with a random access preamble ID (RAPID, Random Access Preamble IDentitfier), and the random access preamble identifier is also included in the random access response message.

After the user equipment receives the random access response message, if the random access preamble identified by the RAPID in the random access response message is the random access preamble sent by the UE, the user equipment considers that the random access response associated with the RAPID is the base station pair. A random access response sent by itself. In the LTE system, the random access response message sent by the base station to the user equipment is carried by the PDSCH. As described above, the user equipment needs to receive the control channel first, and then receive the random access response message according to the indication in the received control channel.

For the user equipment, the control channel may be successfully received, and the random access response message scheduled by the control channel is successfully received, but no random access response is found in the random access response message. That is, in the random access response message, the random access preamble identified by the RAPID corresponding to the random access response is the random access preamble sent by the user equipment. This will waste user equipment detection control The channel and the power consumption of the data channel for detecting the control channel scheduling. Especially for low-cost or low-complexity user equipment, power consumption is critical. One feature of low cost or low complexity user equipment is that the user equipment's operating bandwidth (eg, radio frequency processing bandwidth and/or baseband processing bandwidth) is less than the maximum bandwidth supported by the system.

With coverage enhancement, the control channel requires many iterations to ensure reliable transmission. Random access response messages also require many iterations to achieve reliable transmission. In this way, the user equipment needs to receive the repeated repeated control channels and then receive the data channel that is repeated many times (the data channel carries the random access response message). The user equipment can only determine whether there is a random access response corresponding to the user equipment in the random access response message carried by the data channel only if the repeated control channel and the repeated data channel are successfully detected. Obviously, since the user equipment is to detect the control channel that has been repeated many times and the data channel is repeated many times, the power consumption of the user equipment will be greatly increased.

First, the system architecture of the transmission method of the message of the present invention is introduced. The present invention is mainly applied to an LTE system or an advanced LTE-Advanced (LTE-Advanced) system. The present invention can also be applied to other communication systems, for example, Wideband Code Division Multiple Access (WCDMA), Time Division-Synchronous Code Division Multiple Access (TD-SCDMA), and the like. As long as there is an entity in the communication system that can send a message, there are other entities in the communication system that can receive the message. For example, the message is one or more of system information, a Random Access Response (RAR) message, and a paging message.

Referring to FIG. 1 , a system architecture diagram of a method for transmitting a message according to the present invention is applied to a communication system. As shown in FIG. 1 , a base station (English name Base station) and user equipment (UE, User Equipment) 1 to UE 6 are shown. Forming a communication system, in which the base station transmits one or more of system information, RAR message and paging message to one or more UEs of UE1 to UE6, and the base station is a method for transmitting information of the present invention. The transmitting end device, UE1 to UE6, is a receiving end device in the method for transmitting information of the present invention. In addition, UE4 to UE6 also form a communication system, in which UE5 can be implemented as a function of a base station, and UE5 can send one or more of system information, RAR message and paging message to UE4 and UE6. One or more UEs.

The details are described below separately.

An embodiment of the method for transmitting a message of the present invention is applicable to the sending of a message by a base station. Referring to FIG. 2, the method for transmitting the message may include the following steps:

201. Send control information to the first UE by using a first control channel, where the control information includes UE identification information of one or more UEs.

In the embodiment of the present invention, the base station uses the control channel to schedule control information, and the base station sends the control information through the control channel, which may be broadcast or multicast, and the base station may send the control information to multiple UEs. The first UE may be specifically referred to as one UE served by the base station, or generally refers to one or multiple UEs served by the base station. Specifically, the control information sent by the base station is carried in the first control channel. For example, the control information may be system information, system information block, control information of scheduling system information, control information of scheduling system information block, control information for scheduling random access response, control information for scheduling paging message, and control information of scheduling group message. One or more of a main information block, proprietary data, control information for scheduling proprietary data, and control information for scheduling a common message.

In the embodiment of the present invention, the control information carried by the base station in the first control channel includes control information of the base station to one UE or multiple UEs. The base station performs control indication on which UE or UEs, and carries the identifier of the UE in the control information, and then the base station carries the control information in the first control channel for transmission. For example, the base station provides a total of n UEs (respectively referred to as UE1, UE2, ..., UEn). If the base station needs to send a data channel to UE4 of the n base stations, the base station needs to control information carried by the first control channel. Carry the identity of UE4. Then, for the UE4, by detecting the control information carried by the first control channel, it can be determined that the base station will have data to be sent to the UE4. If the base station needs to send the data channel to the other one of the n UEs or the multiple UEs, the base station needs to carry the identifiers of the UEs in the control information carried by the first control channel.

In some embodiments of the invention, there are multiple types of control information carried by the base station in the first control channel. For example, the control information further includes one or more of the following information: frequency hopping setting information, resource configuration information, modulation and encoding information, power control information, format distinguishing information, acknowledgement information, and negative acknowledgement information. For example, the frequency hopping setting information refers to control information indicating frequency hopping, the resource configuration information refers to control information for configuring various transmission resources, and the modulation and coding information refers to configuring the modulation mode and the coding mode. The control information, the power control information refers to information that controls the transmission power, the format discrimination information is information indicating the format of the data, and the positive response information and the negative response information refer to control information that indicates the response. In the embodiment of the present invention, the information that is already existing may be used as the control information, and the control information carries the UE identifier that the base station indicates to one or more UEs. For example, the identity of one or more UEs may be carried in the modulation and coding information to indicate to all UEs served by the base station.

In the embodiment of the present invention, the UE identity information carried by the base station in the control information may be partial information or all information in the first identifier information. Specifically, the first identifier information includes one or more of the following information: a random access preamble identifier, a resource identifier used by the UE, a temporary mobile station identifier (S-TMSI, SAE Temporary Mobile Station Identifier), and an international mobile subscriber identifier. (IMSI, International Mobile Subscriber Identity), International Mobile Equipment Identity (IMEI), wireless network temporary identity, randomly generated identity, paging UE ID identity.

When the base station needs to perform control indication on which UE or UEs in the control information, the base station may use the UE identifier to indicate a specific UE. The UE identity may be of different types as long as the UE identity used by the base station can be identified by the UE side. Without limitation, the UE identifier may be the entire one in the first identification information. Part information, the first identification information may be a random access preamble identifier, a resource identifier used by the UE, a temporary mobile station identifier S-TMSI, an international mobile subscriber identity IMSI, an international mobile equipment identity IMEI, a wireless network temporary identifier, and a randomly generated One or more of identification, paging UE ID identification, and the like. In addition, in order to reduce the cost of checking the control information on the UE side, the UE identifier information carried in the control information may be only part of the information in the first identifier information, and the UE only needs to check the first identifier information carried in the control information. Part of the information is sufficient, and it is not necessary to detect all the information of the first identification information, so that the detection overhead is small for the UE. For example, the UE identification information may be part of the first identification information. If the UE identifier is 40 bits, the UE identification information carried in the control information includes only 20 bits.

It should be noted that, in the prior art, the control information carried by the control channel does not include the UE identification information, but in the present invention, in order to enable each UE to determine in time whether the base station sends data to itself, the base station is in the control information. Direct indication of which UEs will need to receive data scheduled by the control channel. In the embodiment of the present invention, the control information is sent by the base station to the first UE by using the first control channel, and the control information has a indication to the first UE whether there is still a data channel for scheduling.

202. Send, according to the first control channel, a first message scheduled by the first control channel, where the first message includes information that is transmitted by the base station to one or more UEs.

In the embodiment of the present invention, the base station sends control information to the first UE, where the first UE may be specifically referred to as one UE served by the base station, or generally refers to one or more UEs served by the base station. After transmitting, by the base station, the first control channel, the first message scheduled by the first control channel is sent according to the previously transmitted first control channel. The first message may be data carried by the data channel, and the destination UE that the base station sends the first message is indicated by the UE identity information included in the control information. The UE under the service of the base station only needs to determine, according to the control information, whether the first message scheduled by the base station and scheduled by the first control channel is a message sent to the UE.

In the embodiment of the present invention, the first message sent by the base station is scheduled by the first control channel. The first message can have different message types in different application scenarios. For example, in a random access scenario, the first message scheduled by the base station through the first control channel may be a random access response message. In the paging scenario, the first message scheduled by the base station through the first control channel may be a paging message.

It should be noted that, in some embodiments of the present invention, the UE information is not included in the first message. Or, the first message includes other information except the UE identification information in the first identification information. That is, in the prior art, the base station needs to send data to which UE or UEs, and the base station will be in the first A message carries UE identification information. For the UE, the UE needs to receive the control information of the control channel scheduling and also needs to receive the first message. After the control information and the reception of the first message, the UE can determine whether there is data sent to the UE itself. In the embodiment of the present invention, the manner in which the base station carries the UE identification information in the first message is changed, and the first message does not carry the UE identification information, but the control information scheduled by the first control channel carries the UE identification information. Therefore, the UE can directly determine whether there is still a first message sent to the UE itself after receiving the control information. If the control channel indicates that a message is sent to the UE, the UE will receive the message. If the control channel indicates that no message is sent to the UE, the UE does not receive the first message. For the UE, power consumption can be saved. In some embodiments of the present invention, the first message includes other information than the UE identification information in the first identification information. For example, in different scenarios, the other information included in the first message is also different. For example, the first message may include one or more pieces of information in the first identification information other than the UE identification. For example, the first identification information is a paging UE ID. If the length of a paging UE ID is 40 bits, the first message may be one of the paging UE IDs, and the control channel for scheduling the first message includes the other 20 bits of the paging UE ID.

In some embodiments of the present invention, if the base station schedules multiple control channels, the base station may further indicate the control channel transmitted after the control information carried by the first control channel. For example, the control information further includes indication information, the indication information includes related information for transmitting the second control channel, or the indication information includes related information for transmitting the second message scheduled by the second control channel, where the first control channel and the second control The channels are different control channels. That is to say, the control information previously transmitted by the base station includes indication information of the second control channel transmitted later. If the base station uses the broadcast mode to send the control information, the UE served by the base station can receive the indication information carried in the control information, thereby obtaining an indication of the second control channel transmission by the base station, and the UE can determine whether to receive the second control channel. Thereby, the power consumption of the UE can be saved. In some embodiments of the present invention, the method for transmitting a message further includes the step of: the base station transmitting the second message through the second control channel.

Further, in some embodiments of the present invention, the first control channel is a physical control channel for scheduling a random access response message, the second control channel is a physical control channel for scheduling a contention resolution message, and the second message is a contention resolution message.

The foregoing description of the present invention shows that the base station first sends control information to the first UE, and the control information includes UE identification information of one or more UEs, and the base station sends the first control channel that carries the control information to the first UE. And finally transmitting the first control channel scheduling according to the first control channel The first message, wherein the first message includes information that the base station transmits to one or more UEs. The base station indicates the first message to be transmitted by using the first transmitted control information, and then, for the UE, the first control channel may be received first, and the first message scheduled by the first control channel is determined according to the first control channel, because the UE may The first control channel transmitted by the base station is used to identify whether there is a data channel transmitted to itself, so that the UE can determine whether the data channel needs to be received early, thereby reducing the complexity of the UE detecting the message and saving the power consumption of the UE.

In the foregoing embodiment, the method for transmitting a message is described from the base station side, and then the method for transmitting the message provided by the present invention is described from the peer device (UE) side of the base station. Referring to FIG. 3, another embodiment of the present invention is shown. The method for transmitting the provided message may include the following steps:

In the embodiment of the present invention, the base station uses the control channel to schedule control information, and the base station sends the control information through the control channel, which may be a broadcast or multicast manner. The base station can transmit control information to a plurality of UEs. The first UE may be specifically referred to as one UE served by the base station, or generally refers to one or more UEs served by the base station. Specifically, the control information sent by the base station is carried in the first control channel. For example, the control information may be system information, system information block, control information of scheduling system information, control information of scheduling system information block, control information for scheduling random access response, control information for scheduling paging message, and control information of scheduling group message. One or more of a main information block, proprietary data, control information for scheduling proprietary data, and control information for scheduling a common message.

In the embodiment of the present invention, after the base station broadcasts the first control channel, the first UE may receive the first control channel, and the control information may be determined from the first control channel. Here, the first UE may specifically refer to a certain UE served by the base station, or generally refers to one or more UEs served by the base station. The control information carried by the base station in the first control channel includes a control indication of the UE or the UEs by the base station, and the UE may perform the control indication on the UE or the UEs, and the identifier of the UE may be carried in the control information, and then the base station will The control information is carried in the first control channel for transmission. For example, the base station provides a total of n UEs (respectively referred to as UE1, UE2, ..., UEn). If the base station needs to send a data channel to UE4 of the n base stations, the base station needs to control information carried by the first control channel. Carrying the identifier of the UE4, for the UE4, by detecting the control information carried by the first control channel, it can be determined that the base station will have data to be sent to the UE4. If the base station needs to send a data channel to another UE or multiple UEs of the n base stations, the base station needs to carry the control information carried by the first control channel. With the identity of these UEs.

In some embodiments of the invention, there are multiple types of control information carried by the base station in the first control channel. For example, the control information further includes one or more of the following information: frequency hopping setting information, resource configuration information, modulation and encoding information, power control information, format distinguishing information, acknowledgement information, and negative acknowledgement information. The frequency hopping setting information refers to control information indicating frequency hopping, the resource configuration information refers to control information for configuring various transmission resources, and the modulation and coding information refers to configuring the modulation mode and the coding mode. The control information, the power control information refers to information that controls the transmission power, the format discrimination information is information indicating the format of the data, and the positive response information and the negative response information refer to control information that indicates the response. In the embodiment of the present invention, the information that is already existing may be used as the control information, and the control information carries the UE identifier that the base station indicates to one or more UEs. For example, the identity of one or more UEs may be carried in the modulation and coding information to indicate to all UEs served by the base station.

In the embodiment of the present invention, the UE identity information carried by the base station in the control information may be partial information or all information in the first identifier information. Specifically, the first identifier information includes one or more of the following information: a random access preamble identifier, a resource identifier used by the UE, a temporary mobile station identifier S-TMSI, an international mobile subscriber identity IMSI, an international mobile device identifier IMEI, The wireless network temporary identifier, the randomly generated identifier, and the paging UE ID identifier.

When the base station needs to perform control indication on which UE or UEs in the control information, the base station may use the UE identifier to indicate a specific UE. The UE identifier may be implemented in multiple manners as long as the UE identifier used by the base station can be identified by the UE side. The UE identifier may be all information in the first identifier information, and the first identifier information may be a random access preamble identifier, a resource identifier used by the UE, a temporary mobile station identifier S-TMSI, and an international mobile subscriber identity IMSI. And one or more of an international mobile device identifier IMEI, a wireless network temporary identifier, a randomly generated identifier, a paging UE ID identifier, and the like. In addition, in order to reduce the cost of checking the control information on the UE side, the UE identifier information carried in the control information may be only part of the information in the first identifier information, and the UE only needs to check the first identifier information carried in the control information. Part of the information is sufficient, and it is not necessary to detect all the information of the first identification information, so that the detection overhead is small for the UE. For example, the UE identification information may be part of the first identification information. If the UE identifier is 40 bits, the UE identification information carried in the control information includes only 20 bits.

It should be noted that the control information carried by the control channel in the prior art does not include the UE identifier. Information, but in the present invention, in order to enable each UE to determine in time whether the base station transmits data to itself, the base station directly indicates in the control information which UEs will need to receive data scheduled by the control channel. In the embodiment of the present invention, the control information is sent by the base station to the first UE by using the first control channel, and the control information has a indication to the first UE whether there is still a data channel for scheduling.

302. The first UE determines, according to the control information, a first message scheduled by the first control channel, where the first message includes information that is transmitted by the base station to one or more UEs.

In the embodiment of the present invention, the base station sends control information to the first UE, where the first UE may be specifically referred to as one UE served by the base station, or generally refers to one or more UEs served by the base station. After transmitting, by the base station, the first control channel, the first message scheduled by the first control channel is sent according to the previously broadcasted first control channel, where the first message may be data carried by the data channel. The destination UE that the base station sends the first message indicates by the UE identification information included in the control information. The UE under the service of the base station only needs to determine, according to the control information, whether the first message scheduled by the base station and scheduled by the first control channel is sent to the UE itself.

In some embodiments of the present invention, step 302, the first UE determines a first message scheduled by the first control channel, and includes the following steps:

The UE identifier indicated by the UE identity information included in the control information matches the identifier of the first UE, and receives the first message sent by the base station; or

The UE identifier indicated by the UE identity information included in the control information does not match the identifier of the first UE, and does not receive the first message sent by the base station.

That is, the base station includes only the UE identification information that the base station needs to further transmit the first message in the control information. If the first UE is the UE that needs to further transmit the first message, the UE identifies the UE identification information and the If the first UE is not the UE that needs to further send the first message, the UE identification information included in the control information does not match the identifier of the first UE.

For example, the first control channel is a broadcast or multicast control channel, that is, it can be received by many UEs (for example, UEs served by the base station are UE1, UE2, and UE3). However, the control information includes UE identification information, such as UE1 identification information and UE2 identification information. Then, UE1 and UE2 detect the first control channel, and find that the UE identifier in the control channel matches its own, then it knows that the data channel scheduled by the first control channel does have its own information, so UE1 and UE2 receive the control channel scheduling again. The data. But UE3 detects the first control channel and finds the first control channel. If there is no identifier, the data channel scheduled by the first control channel does not have its own information, so that the UE3 does not receive the data channel scheduled by the first control channel, which saves the power consumption overhead of the UE3.

According to the existing implementation manner, the first control channel does not carry the UE identifier, and the data channel carried by the first control channel carries the UE identifier. Therefore, UE1, UE2, and UE3 must receive the first control channel and the data channel. It is determined whether the data channel has its own information. According to the implementation of the prior art, the UE3 finds that there is no information in the data channel, so the UE3 detects the data channel in vain. In the embodiment of the present invention, the UE identifier in the data channel is put into the first control channel, so that the UE detects the first control channel, and can determine whether the subsequent data channel needs to be received according to the UE identifier. The UE identity matches to receive the data channel. If the UE identifiers do not match, the data channel is not received, thereby optimizing the receiving performance of the UE.

In the embodiment of the present invention, the first message sent by the base station is scheduled by the first control channel, and the first message may be data scheduled by the data channel. In different application scenarios, the first message may have different types. For example, in a random access scenario, the first message scheduled by the base station through the first control channel may be a random access response message. In the paging scenario, the first message scheduled by the base station through the first control channel may be a paging message.

It should be noted that, in some embodiments of the present invention, the first message may not include the UE identifier information; or the first message includes other information in the first identifier information other than the UE identifier information. That is, in the prior art, the base station needs to transmit data to the UE or the UE, and the base station carries the UE identification information in the first message. For the UE, the UE needs to receive the control information of the control channel scheduling and needs to receive the information. The first message, after the control information and the reception of the first message, can the UE determine whether there is data sent to the UE itself. In the embodiment of the present invention, the manner in which the base station carries the UE identification information in the first message is changed, and the UE does not carry the UE identification information in the first message, but carries the UE identification information in the control information scheduled by the first control channel, thereby The UE can directly determine whether there is still a first message sent to the UE itself after receiving the control information. If the UE ID in the control channel matches the ID of the UE, the UE receives the first message. Otherwise, the UE will no longer receive the first message. In this way, power consumption can be saved for the UE. In some embodiments of the present invention, the first message includes other information than the UE identification information in the first identification information, for example, the information included in the first message is different for different first message types. For example, the first message may include one or more pieces of information in the first identification information other than the UE identification.

In some embodiments of the present invention, if the base station schedules multiple control channels, the base station may also pass The control information carried by the first control channel indicates the control channel transmitted later. For example, the control information further includes indication information, where the indication information includes related information for transmitting the second control channel, or the indication information includes scheduling for transmitting the second control channel. Information about the second message, wherein the first control channel and the second control channel are different control channels. That is, the control information transmitted by the base station includes the indication information of the second control channel that is transmitted later. If the base station sends the control information by using the broadcast mode, the UE served by the base station can receive the indication carried in the control information. Information, thereby obtaining an indication of the second control channel transmission by the base station, and the UE may determine whether to receive the second control channel, thereby saving power consumption of the UE.

In the foregoing implementation scenario of the present invention, the method for transmitting a message further includes the following steps: the first UE receives the second control channel according to the control information. In other words, the first UE determines that the second control channel scheduled by the base station needs to be received by the first UE according to the indication information carried in the control information, and the first UE may continue to receive the second control channel after receiving the first control channel, so that Determining a second message carried by the second channel.

It should be noted that, in the present invention, the control information is carried in the control channel, and the user equipment can determine whether there is a random access response of the UE in the random access response message scheduled by the control channel by detecting the control channel, thereby optimizing the user equipment. The problem of the data channel reception is that the user equipment saves the overhead of the data channel and reduces the power consumption of the user equipment. However, the problem background and solution of the present invention are equally applicable to the transmission of other messages, as long as the message is Dispatched by the control channel, and the message may contain information for a plurality of user equipments. For example, the first message may be a paging message in addition to the random access response message.

According to the description of the present invention, the first UE receives the first control channel sent by the base station, and the first control channel carries control information, where the control information includes UE identification information of one or more UEs, and the first UE according to the Determining, by the control information, a first message scheduled by the first control channel, where the first message includes information that the base station transmits to one or more UEs. The base station indicates the first message to be transmitted by using the first transmitted control information, and then, for each UE, the first control channel may be received first, and the first message scheduled by the first control channel is determined according to the first control channel, because the UE The first control channel transmitted by the base station can be used to identify whether there is a data signal transmitted to itself. Therefore, the UE can determine whether the data channel needs to be received early, thereby reducing the complexity of the UE detecting the message and saving the power consumption of the UE.
