Description

Method for transmitting information and 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 transmitting information, a base station, and a user equipment.

Background technique

The Internet of Things (IoT) refers to the network that realizes the interconnection of people, things, objects and objects by deploying various devices with certain sensing, computing, execution and communication capabilities to acquire information of the physical world and realize information transmission, coordination and processing through the network. . In short, the Internet of Things is to achieve the interconnection of people and things, things and things. Possible applications include smart grid, smart agriculture, intelligent transportation, and environmental testing.

The 3rd Generation Partnership Project (English name: 3GPP) of the Mobile Communications Standardization Organization is conducting technical research and standard optimization work for the Internet of Things business. Its main research and optimization direction is cost reduction and coverage enhancement. In terms of cost reduction, the working bandwidth of the terminal device can be reduced. For example, the working bandwidth of the terminal device is 1.4 MHz, which is an important research direction. The coverage enhancement is mainly for the type of machine communication in the basement and other road loss (English full name) :Machine Type Communication, English abbreviation: MTC) The device provides coverage enhancement support, so that the above devices in special scenarios can access the network to obtain services. Among them, signal repetition transmission is one of the methods to achieve coverage enhancement. Under the technique of signal repetition, it can bring certain coverage enhancement, but it may consume more resources. How to improve resource utilization is a problem that needs to be solved in the case of using signal repetition to achieve coverage enhancement.

For the random access response (English name: Random Access Response, English abbreviation: RAR) message or paging message, according to the current protocol, the random access response message or the paging message is through the physical downlink control channel (English full name: Physical Downlink) The Control Channel (English abbreviation: PDCCH) is a physical downlink shared data channel (English name: Physical downlink shared data channel, English abbreviation: PDSCH). The user equipment (English name: User Equipment, English abbreviation: UE) needs to receive the PDCCH first, and obtain the transmission block size of the random access response message (or paging message) according to the indication of the control information in the received PDCCH (English full name: Transport Block Size (English short name: TBS), and then perform a random access response message according to the determined TBS (or Reception of paging messages).

In a scenario where coverage enhancement transmission is required for a random access response message (or a paging message), the user equipment first receives a control channel of the scheduling information before receiving the random access response message (or paging message), according to the received The control channel determines the transport block size carrying the random access response message (or paging message), and then receives the random access response message (or paging message) according to the determined transport block size. In order for the user equipment to successfully receive the random access response message (or paging message), the control channel needs to be repeated many times, and the random access response message (or paging message) also needs to be repeated many times, thereby increasing the system resource overhead and reducing The resource utilization of the network also greatly increases the detection complexity and power consumption of the user equipment.

Detect the power consumption overhead of the channel.

To facilitate a better understanding and implementation of the foregoing solutions of the embodiments of the present invention, the following application scenarios are specifically illustrated.

For example, in the random access procedure of the existing LTE system, the UE needs to send a random access preamble first. After the UE sends the random access preamble, the UE receives the random access response message. The base station includes one or more random access responses in the random access response message to the UE. The random access response includes a random access preamble identifier (English name: Random Access Preamble IDentitfier, English abbreviation: RAPID). For example, the RAPID identifies the pre-random access sent by the base station. guide. After the UE receives the random access response, if the random access preamble identified by the RAPID in the random access response is the random access preamble sent by the UE, the UE considers that the random access response is the random access preamble sent by the base station to itself. the response to. In the LTE system, the random access response message sent by the base station to the UE is carried over the PDSCH. The UE needs to first receive the control channel, obtain the transport block size of the random access response message according to the indication of the control information in the received control channel, and then perform the random access response message according to the determined transport block size.

Taking the processing of the paging message as an example, in the existing LTE system, the idle UE needs to monitor the paging message to determine whether the network side or the base station has paged the UE. The UE in the connected state needs to listen to the paging message to determine whether the system information has been updated. The paging message sent by the base station to the UE is carried over the data channel, and the data channel is scheduled by the control channel. Therefore, when the UE listens to the paging message, it needs to first detect the control channel for scheduling the paging message. Only when the control channel is successfully detected, the data channel carrying the paging message is received according to the indication of the control channel.

For the idle state UE, once the UE successfully detects the data channel carrying the paging message, the UE needs to perform its own paging UE (English name: Identity, English abbreviation: ID) and the paging UE ID carried in the paging message. Match, if the match is successful, the UE considers that the UE or the base station has paged the UE. Otherwise, the UE considers that the paging message does not page the UE. For the UE in the connected state, once the UE successfully detects the data channel carrying the paging message, the UE needs to see whether the system information modification is indicated in the paging message.

One or more paging UE IDs may be included in one paging message. Thus, a paging message can initiate paging for one or more UEs. As described above, after the UE needs to successfully detect the paging message of the control channel and the control channel scheduling, it can determine whether the paging message has paged the UE or whether the paging message indicates that the system message is updated. For the UE, the paging message of the control channel and the control channel scheduling may be successfully detected, but it is found that the paging message does not page the UE or the paging message does not indicate system information update. This way the UE consumes a lot of power in vain. Especially for low-cost or low-complexity UEs, power consumption issues are even more critical.

In the random access procedure and the paging process implemented as above, the method for transmitting information provided by the embodiment of the present invention may be performed. The base station performs a simplified design on the first downlink control information for scheduling the first information. The following is an example. The embodiment of the present invention provides a method for transmitting downlink control information and a first information transmission, where the first information is a random access response message and/or a paging message, and the transmission of the first information is performed by the first downlink control information. Scheduling. The embodiment of the invention mainly solves the first downlink control When the first information is scheduled, the first downlink control information specifically includes what content.

In some embodiments of the present invention, the first downlink control information may include: indication information of a narrowband resource used for the first information transmission. Considering coverage enhancement or support for low complexity or low cost UEs, some narrowband resources may be partitioned in the system for coverage enhanced transmission or for low complexity (or low cost) UE services. A narrowband resource or narrowband is a specific frequency resource, and a narrowband resource may be composed of one or more resource blocks or one or more subcarriers. Among them, low complexity (or low cost) UEs can only receive and/or transmit information on a narrow band at the same time. Therefore, the first information can only be transmitted on one narrow band. The first downlink control information may include a narrowband resource indicating that the first information transmission is located. For example, the number of bits (in English: bits) required to indicate a narrowband resource is: log2 (floor(NDLRB/6) or floor(log2(NDLRB/6)), or ceil(log2(NDLRB/6)). For example, a physical resource block (English full name: Physical Resource Block, English abbreviation: PRB) constitutes a narrow band. If the narrow band size is n, the required bit of the field can be: log2 (floor(NDLRB/n)) or floor( Log2(NDLRB/n)), or ceil(log2(NDLRB/n)), where NDLRB is the downlink bandwidth in PRB. For example, the bandwidth of 1.4MHz has 6 PRBs. The 20MHz bandwidth has 100 PRBs, so it can Divided into 16 narrowbands, you need 4 bits of indication. The floor function means rounding down, the ceil function means rounding up, or the number of bits required to indicate narrowband resources is: floor(log2(M)) or ceil( Log2(M)), where M is the number of narrowbands configured by the base station.

In some embodiments of the present invention, the first downlink control information may include: resource allocation indication information in a narrowband used for the first information transmission. Taking a narrowband including 6 PRBs as an example, the resource allocation in the narrowband indicates the location of the narrowband of the 6PRB, that is, the resource allocation in the narrowband specifically indicates which of the six PRBs in the narrowband are used for the random access response. transmission. An example of a bit required for resource allocation indication information in a narrowband is as follows: if the first information transmission occupies all PRBs of a narrowband, the field may be omitted. For example, 6 PRB indications may be performed in a manner indicated by a bitmap. . In order to reduce the number of indicated bits, the number of PRBs occupied by the first information transmission and the possible PRB positions may be defined. For example, it is assumed that the indexes of the PRBs included in the narrowband are: PRB n, PRB n+1, PRB n+2, PRB n+3, PRB n+4, PRB n+5. Limiting the first information transmission only takes 2 PRBs, 4 PRBs, and 6 PRBs. As shown in Table 1 below, a method of indicating the narrowband resources used for transmission with 3 bits is illustrated. It can be understood that Table 1 below is only an example, and the correspondence between the resource status indicator bit in the narrowband and the resource indication in the narrowband can also be changed.

As shown in Table 2 below, a method of indicating the narrowband resources used for transmission with 2 bits is illustrated.

It should be noted that, in the table of Table 1 and Table 2 in the embodiment of the present invention, the correspondence between the in-band resource indication bit state and the intra-narrowband resource indication is only exemplary. In fact, the intra-narrowband resource indicates the bit state and the intra-narrowband resource. The indicated correspondence can be transformed. As long as the bit is used for the control channel transmission, the resource allocation indicating 2 RBs, 4 RBs, and 6 RBs in the narrowband, or the transmission of the control channel in the bits indicates the resource allocation of 4 RBs and 6 RBs in the narrowband. Yes, without being limited to the table above.

In some embodiments of the present invention, the first downlink control information may include: modulation coding method indication information of the first information transmission, and the bit required for the field may be determined according to the number of supported modulation coding modes. For example, if a fixed modulation coding mode is supported, or the modulation coding mode is implicitly determined based on other information, the field may not be included. For example, the modulation coding method can be indicated by 2 to 4 bits.

In some embodiments of the present invention, the first downlink control information may include: the first information transmission Frequency hopping indication information. A frequency hopping configuration for indicating the first information transmission. This field may not be included if the transmitted first information is always frequency hopped, or if the transmission of the first information is always not frequency hopping, or if the frequency hopping is pre-defined or pre-configured. The frequency hopping configuration can be indicated by 0 to 2 bits.

In some embodiments of the present invention, the first downlink control information may include: authorization distinguishing indication information, and a distinguishing indication for the uplink grant and the downlink grant. If the UE needs to detect whether the downlink control information is used for uplink scheduling in the search space of the control channel for scheduling the first information transmission, and the downlink control information size of the uplink scheduling is the same as the downlink control information of the scheduling first information, One bit indicates the uplink grant and the downlink grant. If the UE's control channel in the search space for scheduling the control channel of the first information transmission is not used for uplink scheduling, then this field is not required to distinguish between the uplink grant and the downlink grant. Considering that the narrowband has only 6 PRBs, and the control channel scheduling the first information transmission needs to occupy more resources or repeat the guarantee performance, it may be specified that the uplink grant is not detected in the search space of the control channel that schedules the first information transmission. This may not include the field, thereby saving the load of the first downlink control information.

In some embodiments of the present invention, the first downlink control information may include: system information update indication information (English name systemInfoModification). For example, one bit may be used to indicate system information update in the first downlink control information. For example, if the first downlink control information indicates systemInfoModification, the UE considers that system information may have been updated. Of course, it is also possible to indicate in the first downlink control information which specific system information has been updated. For example, it may be a bitmap (English name bitmap) mode indication or a multi-bit joint indicating which system information has been updated.

In some embodiments of the present invention, the first downlink control information may include: an alarm indication information of a seismic typhoon warning system (English name: Earthquake and Tsunami Warning System, English abbreviation: ETWS). For example, the ETWS can be indicated by 1 bit in the first downlink control information.

In some embodiments of the present invention, the first downlink control information may include: an alarm indication information of a commercial mobile alert service (English full name: Commercial Mobile Alert Service, English abbreviation: CMAS). For example, the CMAS can be indicated by 1 bit in the downlink control information.

In some embodiments of the present invention, the first downlink control information may include: transport block size indication information of the first information transmission. If the transport block size of the first information transmission is determined according to other already indicated parameters, the field in the first downlink control information does not need to indicate the transport block size. Otherwise, the size of the transport block needs to be indicated in the first downlink control information, for example, the transport block size is indicated by 2 bits.

In some embodiments of the present invention, the first downlink control information may include: the first information transmission Override enhanced transmission indication information. The coverage enhanced transmission indication information is coverage enhancement level information or repetition number information or bundle transmission size information. If the coverage enhancement transmission indication information of the first information transmission is determined according to the repetition level (or the number of repetitions) of the channel before the first information transmission, the first downlink control information does not need the coverage enhanced transmission indication information indicating the first information transmission. . The channel before the first information transmission may be a random access preamble, or a control channel for scheduling a random access response, or a control channel for scheduling a paging message. Otherwise, the coverage enhancement indication information may be indicated by 1 to 3 bits. The number of repetitions of the first information may be the number of repetitions A plus the number of repetitions B. The number of repetitions A is the number of repetitions determined according to the coverage enhancement level or the number of repetitions of the high layer signaling configuration or a predetermined number of repetitions. The number of repetitions B is the number of repetitions indicated by the downlink control information. Therefore, the number of repetitions B indicated by the downlink control information can be regarded as a fine adjustment of the number of repetitions A. Of course, it is also the content of the present invention to replace the above repetition number with the bundle transmission size.

In some embodiments of the present invention, the first downlink control information may include: indication information of the downlink control information format, and whether the downlink control information needs to be the control information for scheduling the first information, or the downlink control information carries the first information. Control information. The distinguishing method includes, but is not limited to, a display field indication in the first downlink control information, such as a distinction using 1 bit, or a joint indication of format differentiation and authorization distinction using 2 bits.

In some embodiments of the present invention, different control channel scrambling codes may also be used to distinguish whether the downlink control information is control information for scheduling the first information or the control information for carrying the first information for the downlink control information. For example, if the downlink control information carries the first information, the redesigned wireless network temporary identifier (English name: Radio Network Tempory Identity, RNTI) or the RNTI set is used, and the first information is scheduled for the downlink control information, and the existing information is used. RNTI.

Or implicitly determining the content or function of the downlink control information according to the coverage enhancement level or channel quality. For example, the downlink control information corresponding to the coverage enhancement level Y bears (ie, includes) the first information, and the downlink control information corresponding to the coverage enhancement level X schedules the first information. The number of repetitions required to cover the enhancement level X is generally less than the number of repetitions required to cover the enhancement level Y. For example, the downlink control information corresponding to the coverage enhancement bears (ie, includes) the first information, and the downlink control information corresponding to the non-coverage enhancement schedules the first information.

In some embodiments of the present invention, the first downlink control information may include: random access preamble indication information, and the indication information of the random access preamble may be a simplified random access preamble identifier (English name: Random Access Preamble IDentitfier, English abbreviation: RAPID). The RAPID is used to identify the random access preamble randomly selected by the UE during the random access procedure. The existing LTE protocol supports 64 random access preambles on one PRACH resource, so the RAPID is required to indicate 6 bits. In the coverage enhancement scenario, the coverage enhancement level (such as the coverage enhancement level is the repetition level or the number of repetitions) and the random access resources have a one-to-one mapping relationship. If the above correspondence is based on the one-to-one correspondence between the preamble packet and the coverage enhancement level, the number of bits indicating the RAPID may be lowered. For example, a total of 64 preambles support a total of three coverage enhancement levels. If the number of preambles of the three levels is approximately equal, one level can have 21 or 22 preambles. Then, only 5 bits are needed to indicate the preamble. Further, if the number of preambles assigned by a certain level is small, the number of bits required to indicate the preamble may be less. If the number of preambles assigned to a certain level is num_preamble, the number of bits required to indicate the RAPID corresponding to the PRACH group may be:

The parentheses in the formula are rounded up.

In addition, the base station may also implicitly indicate the received random access preamble, and the RAPID is not used in the random access response information or indicated by few bits. For example, the wireless network temporary identity that now scrambles the random access response is determined according to the time index (subframe number) of the random access preamble transmission and the frequency resource index. Therefore, the wireless network temporary identifier can implicitly reflect the time index and the frequency resource index. Similarly, if the RNTI is determined according to the index of the random access preamble, the RNTI may implicitly indicate the number of the random access preamble or the random access preamble. For example, assuming that there are 64 RNTIs, each of which corresponds to a random access preamble, the radio network temporary identifier of the scrambled random access response may indicate a random access preamble identifier. For example, if there are 32 RNTIs, each of which corresponds to two random access preambles, the random access response information may further indicate one of the two random access preambles by using one bit. Leading. The RNTI associated with the random access preamble can be configured by pre-defined or signaling. The association between the RNTI and the random access preamble may be pre-defined or signaled. For example, one RNTI set or range is pre-defined, and each RNTI in the RNTI set or range is associated with the determined random access preamble. As another example, the functional relationship between the RNTI and the random access preamble index can be predetermined. That is, RNTI=function(t_id, f_id, preamble_id) or RNTI=function(preamble_id), where t_id is an index of the PRACH time resource (within one or more radio frames). F_id is an index of the PRACH frequency resource. The preamble_id is the index of the preamble. Specifically, a functional relationship is RNTI=1+t_id+N*f_id+M*preamble_id, where N and M are pre-fixed constants. For example, N is the index number of the time resource, and M is the product of the number of indexes of the PRACH frequency resource and the number of indexes of the PRACH time resource.

If the time resource is in units of subframes, a radio frame can have a maximum of 10 subframes to transmit the preamble. That is, N=10. For example, if the PRACH time resource is in units of X subframes, then one radio frame has at most ceil (10/X) time resource transmission preambles, where the ceil is rounded up, that is, N=ceil(10/X). If the PRACH time resource is a resource in Y radio frames, and the PRACH time resource is in units of X subframes, the Y radio frames have a maximum of ceil (Y*10/X) time resource transmission preambles, that is, N=ceil (Y*10/X). For example, in the coverage enhancement scenario, the transmission of the preamble needs to be repeated, so the random access opportunity will be much less in the same time. For example, in the same sub-frame of 10 ms, according to the original protocol, each sub-frame can have random access resources, that is, there are 10 random access opportunities; and in the coverage-enhanced scene, even if the number of repetitions is 2, the maximum is There are also only 5 access opportunities. This can reduce the number of random access opportunities, that is, the number of RNTIs can be reduced.

The index of the PRACH frequency resource and the number of indexes of the PRACH frequency resource may be independently numbered for each coverage enhancement level. For example, the coverage enhancement level 1 has two PRACH frequency resources, the index is {0, 1}, the number of indexes of the PRACH frequency resource is 2, and the coverage enhancement level 2 has three PRACH frequency resources, and the indexes are respectively {0, 1, 2}, the number of indexes of the PRACH frequency resource is 3. The index of the PRACH frequency resource and the index number of the PRACH frequency resource may be multiple coverage enhancement level joint numbers. For example, coverage enhancement level 1 has 2 PRACH frequency resources, the index is {0, 1}, and coverage enhancement level 2 has 3 PRACH frequency resources, and the indexes are {2, 3, 4}, respectively, and the number of indexes of PRACH frequency resources. It is 5. For example, the number of indexes of the PRACH frequency resource may be determined independently by the frequency division duplex system and the time division duplex system, or may be determined according to the number of indexes of the largest PRACH frequency resource in the frequency division duplex system and the time division duplex system. For example, in a frequency division duplex system, there are at most F1 PRACH frequency resources, and in a time division duplex system, there are at most F2 PRACH frequency resources, and the number of indexes of the PRACH frequency resources is equal to Max (F1, F2), where Max is the largest. Value function.

In some embodiments of the present invention, the indication information of the random access preamble is used to indicate whether the base station detects a random access preamble. For example, the indication information of the random access preamble can be indicated by a bitmap. Each bit in the bit string corresponds to whether the base station has received one or more random access preambles. For example, a PRACH resource group includes 16 preambles, and 16 bits can be used to indicate whether the base station detects a random access preamble according to a bitmap indication method, where each bit corresponding to a random access preamble is indicated.

It should be noted that, when only the first downlink control information is a scheduling paging message, the first downlink control information may include an indication of system information update, and the seismic typhoon warning system indicates one of the commercial mobile alarm service indications. Or multiple instructions. When the first downlink control information schedules a random access response cancellation The first downlink control information may include one or more random access preamble identifiers. The number of random access preamble identifiers included in the first downlink control information is known or signaled, and is indicated in the following line control information. If the first downlink control information for maintaining the scheduled random access response transmission (or paging message transmission) has the same size as the second downlink control information for carrying the random access response transmission (or paging message transmission), Scheduling the bits included in the first downlink control information of the random access response transmission (or paging message transmission) to be extended, so that the first downlink control information of the scheduled random access response transmission (or paging message transmission) is included The number of bits is the same as the number of bits included in the second downlink control information carrying the random access response transmission (or paging message transmission). The bits included in the first downlink control information of the scheduled random access response transmission (or paging message transmission) may be extended to form final first downlink control information. The method of bit expansion includes one or more of the following:

All the fields or partial fields of the first downlink control information are repeated, where the repetition may be an integer multiple repetition or a non-integer multiple repetition. In addition, zero padding or padding bits may also be added to the first downlink control information. Or, the (all or part) content of each of the plurality of first downlink control information is cascaded to form a final first downlink control information, where each first downlink control information is used. The association schedules a message. The different first downlink control information of the multiple first downlink control information may be different UE scheduling messages or the same UE scheduling message. The bit in the first downlink control information is encoded, and the coded bit is used as the original bit included in the final downlink control information. For example, the above code is Reed-Sulmon (English full name: Reed-Muller, English abbreviation: RM) coded code or Reed-Solomon (English full name: Reed-Solomon, English abbreviation: RS) code.

Certainly, the field type included in the first downlink control information is independent of the type of information scheduled by the first downlink control information. For example, when the first downlink control information schedules the random access response message, the first downlink control information includes a field type, and the first downlink control information includes the same field type as the first downlink control information when the paging message is scheduled. In addition, it should be noted that whether the first downlink control information is scheduled by the first information may be determined according to an implicit manner. As for the coverage enhancement (eg, repeated transmission) level X, it is determined that the first downlink control information schedules the first information. For the coverage enhancement level Y, it is determined that the first downlink control information does not schedule the first information. The number of repetitions required to cover the enhancement level X is generally less than the number of repetitions required to cover the enhancement level Y.
