Description

Method, base station and terminal for uplink data transmission

Technical field

In the development of communication technology, the communication system between the base station and the User Equipment (UE) has evolved from the Global System for Mobile Communication (GSM) system of the second generation mobile communication technology. The Universal Mobile Telecommunications System (UMTS) system of the third generation mobile communication technology and the Long Term Evolution (LTE) system of the fourth generation mobile communication technology, the current 5G system is about to be put into use. In these communication systems, both uplink and downlink data transmission between the UE and the base station is involved. In order to save the power consumption of the UE, a scheme for unscheduled transmission is proposed. Specifically, the base station broadcasts the uplink resource used for uplink transmission by the UE, and does not initiate a random access waiting base station when the UE has data to transmit. The uplink resources are allocated, and the uplink data packets are directly transmitted by using the competitive resources.

However, the above-mentioned unscheduled transmission scheme is only applicable to a scenario in which a data packet sent by the UE is small or a frequency of transmitting data is low. When a data packet to be transmitted by the UE is gradually increased, or a UE that needs to transmit data per unit time is gradually increased, The resource collision probability in the scheme of the unscheduled transmission is large.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The method according to the embodiment of the present invention can be applied to a Long Term Evolution (LTE) system and a subsequent evolved system, and can also be applied to a Global System for Mobile Communications (GSM) system and a system. A mobile communication system (Universal Mobile Telecommunications System, UMTS for short) is used.

The terminal involved in the embodiment of the present invention, that is, the user equipment, may be a wireless terminal such as a mobile phone or a tablet computer, or a wireless terminal in a Machine to Machine (M2M) communication (for example, a sensor, a meter that can be remotely metered) , or some other smart hardware, etc.). The wireless terminal includes a device that provides voice and/or data services to the user. Alternatively, the device can be a handheld device with wireless connectivity, or other processing device connected to the wireless modem. Moreover, the wireless terminal can also communicate with one or more core networks via a radio access network (eg, RAN, Radio Access Network), for example, the wireless terminal can be a mobile terminal, such as a mobile phone (or "cellular" "Phone" and a computer having a mobile terminal, which may be a portable, pocket-sized, handheld, computer-integrated or in-vehicle mobile device that can interact with the core network for voice and/or data.

A base station according to an embodiment of the present invention may refer to a device in an access network that communicates with a wireless terminal through one or more sectors on an air interface. The base station can be used to convert the received air frame to the IP packet as a router between the wireless terminal and the rest of the access network, wherein the remainder of the access network can include an Internet Protocol (IP) network. The base station may also coordinate the attribute management of the air interface. For example, the base station may be a base station (BTS, Base Transceiver Station) in the GSM system, or may be a base station (NodeB) in WCDMA, or may be an evolved base station in LTE ( eNodeB or eNB or e-NodeB, evolutional Node B), this application is not limited.

Generally, when the UE and the base station perform uplink and downlink data transmission, in the scenario that the data packet sent by the UE continues to be large, the scheduling is completed by the scheduling of the base station, that is, the transmission of the uplink data belongs to the scheduled transmission. For example, as shown in FIG. 1 , the process of transmitting uplink data by a UE in a radio resource control idle (Radio Resource Control_IDLE, RRC_IDLE) state or an out-of-synchronization state is as follows: In the random access, the UE sends a Buffer Status Report (BSR) information to notify the base station (eNodeB) of the current amount of data to be sent; when the UE accesses successfully, the base station allocates resources for uplink transmission to the UE. Then, the UE can perform uplink data transmission through the uplink resource. The above scheduled transmission can effectively avoid resource collision caused by multiple UEs using the same uplink resource at the same time. However, when the data packet sent by the UE is kept small, the UE and the base station in the foregoing scheduling transmission scheme The ratio of the delay caused by the information interaction to the total transmission time will increase, and the ratio of the power consumption of the UE in the information interaction to the total power consumption will also increase. Therefore, the UE generally adopts the method of non-scheduled transmission. The uplink data is transmitted, but when the data packet to be transmitted by the UE is gradually increased, or the number of UEs that need to transmit data per unit time is gradually increased, the resource collision probability in the above-mentioned unscheduled transmission scheme is large.

In actual data transmission scenarios, for example, a scenario in which a packet sent by the UE is large and small, or a scenario in which the frequency at which the UE transmits data is high or low, or a number of UEs transmitting data per unit time is often In the scenario, if the terminal uses the single transmission method to transmit data, the terminal cannot balance the power consumption of the terminal and the probability of resource collision.

The method, the base station, and the terminal for transmitting the uplink data provided by the embodiment of the present invention can solve the problem that the transmission mode suitable for the terminal cannot be determined in different scenarios in the prior art, and the power consumption of the terminal cannot be considered in different scenarios. Technical issues with the probability of collision of resources.

The technical solutions of the present invention and the technical solutions of the present invention are described in detail below with reference to specific embodiments. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in some embodiments.

FIG. 2 is a schematic flowchart diagram of Embodiment 1 of a method for uplink data transmission provided by the present invention. The embodiment relates to determining, according to a second parameter used by the terminal to characterize an actual resource occupied by the terminal for one unscheduled transmission, and a first parameter that is broadcast by the base station for characterizing a maximum resource allowed by the terminal to perform a non-scheduled transmission. Applicable to the current scene transmission mode. As shown in Figure 2, the method includes:

S101: The terminal acquires a resource parameter threshold sent by the base station, where the resource parameter threshold includes a first parameter used to represent the maximum resource allowed by the terminal to perform unscheduled transmission.

Specifically, the terminals involved in the embodiments of the present invention are all terminals in the cell coverage cell that can perform unscheduled transmission. For the unscheduled transmission mode, the base station does not configure dedicated uplink resources for the terminal, but configures competing resources for all terminals in the coverage cell, so that all terminals in the coverage cell compete for use in unscheduled transmission. In the embodiment of the present invention, the base station also configures a competable resource for the terminal in the current resource allocation period, which is called a first competable resource. It should be noted that the base station configures the first competable resource for the terminal to have a resource allocation period. When the base station determines that the currently allocated first competable resource has reached the resource allocation period, the terminal re-allocates the new first competable resource.

After the base station broadcasts the first competable resource in the current resource allocation period, the base station will The obtained resource parameter threshold is also broadcast. When the terminal needs to send the uplink data to the base station, the terminal acquires the resource parameter threshold broadcasted by the base station, reads the first parameter in the resource parameter threshold, and learns, according to the first parameter, the maximum allowed for the current terminal to perform an unscheduled transmission. Resources. Optionally, the resource threshold parameter threshold may be a historical resource parameter threshold that is acquired by the base station, where the historical resource parameter threshold may be a resource parameter threshold in a previous resource allocation period, or may be a resource in a previous resource allocation period. The parameter threshold, that is, the historical resource parameter threshold may be a resource parameter threshold in any resource allocation period before the current resource allocation period, or may be a value set by the operator for the current resource allocation period (for example, the base station is powered on. It can be set manually when starting the operation), or it can be the average of the resource parameter thresholds in the previous multiple resource allocation periods, where the average value can be an arithmetic mean or a weighted average. The manner in which the base station obtains the threshold of the resource parameter is not limited in the embodiment of the present invention. Generally, the base station selects a resource parameter threshold in a previous resource allocation period adjacent to the current resource allocation period as a resource parameter threshold in the current resource allocation period.

S102: The terminal acquires a second parameter used to represent the actual resource occupied by the terminal for performing a non-scheduled transmission.

Specifically, after acquiring the first parameter in the resource parameter threshold, the terminal further acquires a second parameter that can represent the actual resource occupied by the terminal for performing an unscheduled transmission. Optionally, the second parameter may be an explicit “the actual resource occupied by the terminal for one unscheduled transmission”, that is, the second parameter is an actual resource occupied by the terminal for performing a non-scheduled transmission, or the second parameter is further It can be an implicit “real resource occupied by the terminal without scheduling transmission”, that is, the second parameter can determine the actual resource occupied by the terminal for unscheduled transmission.

S103: The terminal determines, according to the value of the first parameter and the value of the second parameter, a transmission mode suitable for the terminal, and sends the uplink data to the base station by using the transmission mode; the transmission manner includes: Schedule a transmission or schedule a transmission.

Specifically, the maximum resources corresponding to the values of the different first parameters are also different, and the actual resources corresponding to the values of the different second parameters are also different. After obtaining the first parameter and the second parameter, the terminal determines a transmission mode suitable for the terminal in the current scenario according to the value of the first parameter and the value of the second parameter, and uses the transmission mode to send uplink data to the base station. Optionally, the terminal may determine, according to the maximum resource corresponding to the value of the first parameter and the actual resource corresponding to the value of the second parameter, a transmission mode suitable for the terminal, and may also correspond to a maximum value according to the value of the first parameter. The ratio of the resource and the actual resource corresponding to the value of the second parameter determines the transmission mode suitable for the terminal.

It should be noted that the foregoing “scenario” may be a scenario in which a data packet sent by the UE is small or a frequency of transmitting data is low, and a scenario in which an uplink data packet to be sent by the UE is relatively large, and an uplink sent by the UE may also be used. When the data packet is large and small, it can also be a scene where the frequency of transmitting data is high and low.

In the prior art, for a scenario in which the uplink data packets to be sent by the UE are relatively large, the terminal uses a single scheduling transmission, and the scenario that the uplink data packets to be sent by the UE are relatively small or the frequency of transmitting data is relatively low. The terminal adopts a single unscheduled transmission, but for the scenario where the uplink data packet sent by the UE is large and small, or the frequency at which the data is transmitted is high and low, the prior art can only adopt a single transmission mode. For data transmission, for example, for a scenario where the uplink data packet sent by the UE is small and small, if the UE only uses simple scheduling transmission, the power consumption of the terminal due to delay waiting for resource scheduling is relatively large, and if the UE Only the simple unscheduled transmission is used, and the probability of resource collision is relatively large, that is, the prior art cannot determine the transmission mode suitable for the terminal in different scenarios, thereby taking into account the power consumption of the terminal and the probability of resource collision; however, In the embodiment of the present invention, the embodiment of the present invention determines an appropriate one according to the value of the first parameter and the value of the second parameter. Transmission of the current scene, which will take into account the power consumption and the resources of the terminal collision probability, increase the transmission efficiency of the terminal, also saves the power consumption of the terminal.

The method for uplink data transmission provided by the embodiment of the present invention, the first parameter sent by the base station for characterizing the maximum resource allowed by the terminal to perform unscheduled transmission and the non-scheduled transmission for characterizing the terminal are obtained by the terminal. The second parameter of the occupied actual resource, and determining the transmission mode suitable for the terminal according to the value of the first parameter and the value of the second parameter, thereby taking into account the power consumption of the terminal and the probability of resource collision, thereby improving the transmission efficiency of the terminal, It also saves power consumption of the terminal.

Specifically, in the LTE system, the foregoing first parameter includes a maximum resource allowed by the terminal to perform unscheduled transmission, a maximum block length allowed by the terminal to perform an unscheduled transmission, and a non-scheduled transmission by the terminal. The second parameter includes: the actual resource occupied by the terminal for one unscheduled transmission, the actual block length of the terminal performing the unscheduled transmission, and the actual time during which the terminal performs the unscheduled transmission. Any one of the above-mentioned "maximum resources allowed by the terminal to perform unscheduled transmission" refers to the maximum number of resource elements (RE elements) that the terminal is allowed to use for one unscheduled transmission. The actual resources occupied by the transmission refers to the actual number of REs occupied by the terminal for one unscheduled transmission. Optionally, the terminal may calculate, according to the block length and the code modulation mode of the uplink data before the coding, the actual RE number that the terminal currently performs for the unscheduled transmission; optionally, the terminal may also use the block length of the uplink data before the coding. The coded modulation mode and the number of subcarriers occupied in the uplink transmission calculate the actual time that the terminal continues to perform the unscheduled transmission.

In the GSM system, the first parameter includes a maximum resource allowed by the terminal to perform a non-scheduled transmission or a maximum block length allowed by the terminal to perform an unscheduled transmission, and the second parameter includes that the terminal performs an unscheduled transmission. The actual resource or the actual block length of the terminal that performs the unscheduled transmission; wherein the above-mentioned "the maximum resource allowed by the terminal to perform unscheduled transmission" refers to the maximum number of slots allowed by the terminal to perform an unscheduled transmission, The actual resource occupied by the terminal for one unscheduled transmission refers to the actual number of slots occupied by the terminal for one unscheduled transmission.

In the UMTS system or the WCDMA system, the first parameter includes a maximum time (or a maximum number of slots) allowed by the terminal to perform an unscheduled transmission, and the second parameter includes an actual time that the terminal continues to perform an unscheduled transmission ( Or the actual number of slots). In addition, in the UMTS system or the WCDMA system, the first parameter further includes a scrambling code set, where the scrambling code set includes N scrambling codes for the base station to descramble the uplink data sent by the terminal, where N is A preset value greater than or equal to 1.

Optionally, the foregoing uplink data may carry the identifier information of the terminal, where the identifier information is used to indicate that the base station sends downlink data corresponding to the uplink data to the terminal. The downlink data corresponding to the uplink data may be an Acknowledge (ACK) or a Non-Acknowledge (NACK). The identifier information may be the identifier information of the entire network level, and may also be the identifier information of the part of the network level. Wherein, the identification information of the entire network level refers to The identification information of the terminal is unique in all the cells covered by the entire base station; the identification information of the part of the network level refers to the identification information of the terminal in a part of the cells covered by the base station. In addition, the identifier information of the terminal carried in the foregoing uplink data may be configured by the network device to the terminal, for example, an MME-Temporary Mobile Subscriber Identity (MME-Temporary Mobile Subscriber Identity) assigned by the Mobility Management Entity (MME). M-TMSI) may also be implemented by the operator into the terminal, for example, the International Mobile Subscriber Identification Number (IMSI).

FIG. 3 is a schematic flowchart diagram of Embodiment 2 of a method for uplink data transmission provided by the present invention. On the basis of the foregoing embodiment, the embodiment relates to a specific process for determining, by the terminal, a transmission mode suitable for the terminal according to the first parameter value and the second parameter value. In this embodiment, the first parameter has a certain correspondence relationship with the second parameter, that is, when the first parameter is the maximum resource allowed by the terminal to perform unscheduled transmission, and the second parameter is occupied by the terminal performing a non-scheduled transmission. Actual resource; or, when the first parameter is the maximum block length allowed by the terminal for unscheduled transmission, the second parameter is the actual block length of the terminal for unscheduled transmission; or, when the first parameter is for the terminal once The maximum time allowed for scheduling transmissions, and the second parameter is the actual time that the terminal continues to perform an unscheduled transmission. As shown in FIG. 3, the above S103 specifically includes:

S201: The terminal determines whether the value of the second parameter is smaller than a value of the first parameter. If yes, execute S202, and if no, execute S203.

Specifically, in this embodiment, the content included in the first parameter and the second parameter has a certain correspondence relationship, that is, the content included in the two items belongs to the same type of content in terms of attributes, and therefore, may be directly according to the first The value of the parameter and the value of the value of the second parameter determine the transmission mode of the terminal. For example, when the first parameter is the maximum block length allowed by the terminal for unscheduled transmission, and the second parameter is the actual block length of the terminal for unscheduled transmission, the terminal can calculate the value of the maximum block length and the actual block length. The value is determined to determine the mode of transmission appropriate for the terminal.

S202: The terminal determines that the transmission mode suitable for the terminal is unscheduled transmission, and sends uplink data to the base station by using unscheduled transmission.

It should be noted that the specific process of the terminal sending the uplink data to the base station by using the unscheduled transmission may refer to the prior art, and details are not described herein again.

S203: The terminal determines that the transmission mode suitable for the terminal is scheduled transmission, and uses the scheduled transmission to send uplink data to the base station.

It should be noted that the specific process of the terminal transmitting the uplink data to the base station by using the scheduled transmission may refer to the prior art, and details are not described herein again.

FIG. 4 is a schematic flowchart diagram of Embodiment 3 of a method for uplink data transmission provided by the present invention. Based on the foregoing embodiment, the embodiment relates to another specific process for determining, by the terminal, a transmission mode suitable for the terminal according to the first parameter value and the second parameter value. In this embodiment, the first parameter and the second parameter also have a certain correspondence relationship, that is, when the first parameter is the maximum resource allowed by the terminal for unscheduled transmission, and the second parameter is for the terminal to perform a non-scheduled transmission. The actual block length or the actual time that the terminal performs the unscheduled transmission; or, when the first parameter is the maximum block length allowed by the terminal for unscheduled transmission, the second parameter is occupied by the terminal for a non-scheduled transmission. The actual resource is either the actual time that the terminal performs the unscheduled transmission; or when the first parameter is the maximum time allowed for the terminal to perform an unscheduled transmission, and the second parameter is occupied by the terminal for a non-scheduled transmission. The actual resource or the actual block length of the unscheduled transmission for the terminal. As shown in FIG. 3, the above S103 specifically includes:

S301: The terminal determines whether the actual resource corresponding to the value of the second parameter is smaller than the maximum resource corresponding to the value of the first parameter. If yes, execute S302, if no, execute S303.

Specifically, in this embodiment, the content included in the first parameter and the second parameter has a certain correspondence relationship, that is, the content included in the two belongs to different types of content in terms of attributes. However, although it is of a different type, the actual resource occupied by the terminal for one unscheduled transmission can be calculated by the actual length of the terminal that performs the unscheduled transmission or the actual time that the terminal performs the unscheduled transmission. The maximum length of the block that the terminal can use for unscheduled transmission or the maximum time for the terminal to perform unscheduled transmission can calculate the maximum resource allowed by the terminal for one unscheduled transmission. That is, through certain calculation methods, different types of content can be normalized.

For example, when the first parameter is the maximum block length allowed for the unscheduled transmission by the terminal, and the second parameter is the actual time that the terminal performs the unscheduled transmission, the terminal may determine the second parameter according to the value of the second parameter. The value corresponding to the actual resource occupied by the terminal for unscheduled transmission, that is, the terminal can determine the actual resource occupied by the terminal for one unscheduled transmission according to the actual time that the terminal performs the unscheduled transmission. The terminal may also determine that the terminal performs an unadjustment according to "the maximum block length allowed by the terminal to perform unscheduled transmission". The maximum resource allowed for transmission (the terminal combines the known coding modulation mode and the maximum block length to determine the maximum resource), so the determined "real resource occupied by the terminal for one unscheduled transmission" can be The terminal performs a size comparison by performing a maximum resource that is allowed to be used for unscheduled transmission, and determines a transmission mode suitable for the terminal.

S302: The terminal determines that the transmission mode suitable for the terminal is unscheduled transmission, and sends uplink data to the base station by using unscheduled transmission.

S303: The terminal determines that the transmission mode suitable for the terminal is scheduled transmission, and uses the scheduled transmission to send uplink data to the base station.

The method for transmitting uplink data provided by the embodiment of the present invention, the first parameter sent by the base station and the second parameter used to represent the actual resource occupied by the terminal for performing unscheduled transmission are obtained by the terminal, and according to the value of the first parameter And the value of the second parameter determines the transmission mode suitable for the terminal, thereby taking into account the power consumption of the terminal and the probability of resource collision, improving the transmission efficiency of the terminal, and saving the power consumption of the terminal.

FIG. 5 is a schematic flowchart diagram of Embodiment 4 of a method for uplink data transmission according to the present invention. This embodiment relates to a specific process in which the terminal further accurately determines a transmission mode suitable for the terminal when the transmission mode determined by the terminal is unscheduled transmission and the uplink data fails to be transmitted to the base station by using the unscheduled transmission. It should be noted that, in this embodiment, the scenario in the foregoing Embodiment 2 is applicable, that is, the scenario in which the content included in the first parameter and the second parameter belongs to the same type of content in terms of attributes. Based on the foregoing second embodiment, the resource threshold threshold may further include a weighting coefficient, which may be a certain type of random number distributed in a certain range. Optionally, the weighting coefficient may be a random number distributed between 0 and 1, may be a random number distributed between 1, 2, and may also be a random number distributed between 0.9 and 1.3.

As shown in FIG. 5, the method includes:

S401: The terminal performs a determining operation, and obtains a determination result. The determining operation includes: determining, by the terminal, whether a product of the value of the second parameter and the weighting coefficient is smaller than the first parameter. The value of the number.

Specifically, when the terminal fails to transmit uplink data by using the determined unscheduled transmission mode (for example, a collision occurs), the terminal re-determines the value of a new second parameter according to the weighting coefficient configured by the base station, that is, the terminal will be the second. The value of the parameter is multiplied by the weighting factor and then it is determined whether the product is less than the value of the first parameter. The purpose of this is to change the value of the second parameter according to a certain distribution law, so that the terminal can quickly determine the transmission mode suitable for itself. It should be noted that, what kind of random number is used for the weighting coefficient, the base station and the terminal may agree in advance, or the base station's weighting coefficient generation method may be broadcasted while the base station broadcasts the resource parameter threshold.

S402: If the judgment result is that the product of the value of the second parameter and the weighting coefficient is greater than the value of the first parameter, the terminal sends the uplink data to the base station by using a scheduled transmission.

S403: If the judgment result is that the product of the value of the second parameter and the weighting coefficient is smaller than the value of the first parameter, the terminal sends the uplink data to the base station again by using unscheduled transmission, and determines Whether the current uplink data fails to be sent; if yes, the terminal obtains a new weighting coefficient, and performs the determining operation by using the new weighting coefficient until the determination result is greater than.

Specifically, when the terminal determines that the product of the value of the second parameter and the weighting coefficient is smaller than the value of the first parameter, the terminal continues to determine that the transmission mode of the terminal is a non-scheduled transmission mode, and then the terminal transmits the unscheduled transmission mode to the base station again. Uplink data, and determine whether the uplink data sent by the current unscheduled transmission fails; if successful, the current unscheduled transmission ends. If it fails, the terminal obtains a new weighting coefficient, optionally, The terminal may acquire a new weighting coefficient according to a preset rule, and the preset rule may gradually double the weighting coefficient as the number of times of unscheduled transmission failure increases. After that, the terminal multiplies the new weighting coefficient and the value of the second parameter again to obtain a new product, and then determines whether the new product is greater than the value of the first parameter, and so on, until the judgment result is greater than the transmission of the terminal. The mode is to schedule the transmission.

Here, a simple example can be used to illustrate the effect of the weighting coefficients. It is assumed that the first parameter is the maximum block length allowed for the terminal to perform an unscheduled transmission, which is 1500 bits, and the weighting coefficients are evenly distributed between 0.9 and 1.3. If the actual block length of a terminal for a non-scheduled transmission is 1400 bits, since the 1400 is less than 1500, the terminal continues to perform unscheduled transmission, but the terminal finds that a resource collision occurs when the unscheduled transmission is used at this time, so the terminal itself generates a weighting factor (the resulting weighting coefficient base station is also known) is 1.2, then 1400*1.2=1680>1500, the terminal switches from unscheduled transmission to scheduled transmission; suppose the actual block length of another terminal for unscheduled transmission is also 1400 bits, but it produces a weighting coefficient of 1.05, then 1400*1.05 When =1470<1500, the terminal continues to perform unscheduled transmission.

The method for transmitting the uplink data provided by the embodiment of the present invention, by setting the weighting coefficient in the resource parameter threshold, enables the terminal to switch to the scheduled transmission in time after determining that the unscheduled transmission fails, thereby further improving the transmission efficiency of the uplink data.

Further, on the basis of all the foregoing embodiments, for the UMTS system, the resource parameter threshold further includes a scrambling code set, where the scrambling code set includes N used by the base station to descramble the uplink data sent by the terminal. Scrambling code. After the terminal determines that the transmission mode of the terminal is unscheduled transmission, the method further includes: the terminal scrambling the uplink data according to the first scrambling code selected from the scrambling code set, and adopting no The scheduled transmission transmits the scrambled uplink data to the base station.

Specifically, in the UMTS system, the terminal determines the process of any of the foregoing embodiments that is still applicable to the transmission mode of the terminal. However, in the prior art, the UMTS system performs scrambling and decoding on the data when performing uplink and downlink data transmission. Disturb. For the above data transmission, it is assumed that the terminal uses the scrambling code A to scramble the uplink data and then sends the data to the base station, and the base station needs to try to use one of the large number of scrambling codes to descramble the scrambling code one by one; however, in this embodiment Since the terminal can select a scrambling code from the set of scrambling codes, then the base station can select a scrambling code in the scrambling code set to perform a descrambling attempt, and the scrambling code selection range of the base station is reduced, thereby reducing the complexity of the base station.

FIG. 6 is a schematic flowchart diagram of Embodiment 5 of a method for uplink data transmission according to the present invention. On the basis of any of the foregoing embodiments, the present embodiment relates to a specific process in which the terminal determines whether the uplink data is only suitable for scheduling transmission according to the service type of the uplink data, that is, the terminal performs a transmission mode pre-determination. As shown in FIG. 6, before S101, the method includes:

S501: The terminal determines, according to the service type of the uplink data, a degree of association between the uplink data and the scheduled transmission in the transmission mode.

Specifically, the terminal may preset an association threshold, which indicates that the uplink data is only suitable for the minimum of scheduling transmission. Therefore, the terminal determines the degree of association between the uplink data and the scheduled transmission according to the service type of the uplink data, and then determines the relationship between the association degree and the association threshold, and the root. According to the judgment result, it is determined whether the uplink data is only applicable to the scheduled transmission.

S502: If the degree of association between the uplink data and the scheduled transmission in the transmission mode is greater than or equal to a relevance threshold, the terminal sends the uplink data to the base station by using a scheduled transmission.

Specifically, when the association degree is greater than or equal to the association threshold, the service type of the current uplink data is a type that can only perform scheduling transmission, and the terminal can only perform scheduling transmission at this time. For example, a time-frequency service is a type of service that can only adjust transmission.

S503: If the degree of association between the uplink data and the scheduled transmission in the transmission mode is less than a correlation threshold, the terminal acquires the resource parameter threshold sent by the base station.

Specifically, when the association degree is less than the association threshold, the service type of the current uplink data is applicable to both the scheduled transmission and the unscheduled transmission (for example, the heartbeat packet, the query sent by the mobile APP to the server, whether there is a new message or not) The transmission mode of the terminal is determined according to the current actual scenario. Therefore, after determining that the association between the uplink data and the scheduled transmission is less than the association threshold, the terminal performs the steps subsequent to S101 and S101 to determine the transmission suitable for the terminal. the way.

The method for uplink data transmission provided by the present invention determines the degree of association between the uplink data and the scheduled transmission in the transmission mode according to the service type of the uplink data, and then determines the suitable terminal according to the relationship between the association degree and the association threshold. The transmission mode, that is, when the association degree is greater than or equal to the association threshold, that is, when the service type of the uplink data is only applicable to the scheduled transmission, the terminal directly performs the scheduling transmission, and does not need to perform subsequent values according to the first parameter. The value of the second parameter determines a process suitable for the transmission mode of the terminal, simplifies the processing flow of the terminal, and saves power consumption of the terminal.

FIG. 7 is a schematic flowchart diagram of Embodiment 6 of a method for uplink data transmission according to the present invention. This embodiment relates to a specific process in which a base station broadcasts a resource parameter threshold to all terminals in its coverage cell, and receives uplink data that is sent by the terminal in a transmission manner suitable for the terminal. As shown in FIG. 7, the method includes:

S601: A base station broadcast resource parameter threshold, where the resource parameter threshold includes a first parameter used to represent a maximum resource that the terminal performs for one unscheduled transmission.

Specifically, for the unscheduled transmission mode, the base station does not configure a dedicated uplink resource for the terminal, but configures competable resources for all terminals in the coverage cell, and is used for competing use by all terminals in the coverage cell for unscheduled transmission. . In the embodiment of the present invention, the base station also configures a competable resource for the terminal, which is called a first competable resource. It should be noted that the base station configures the first competing terminal for the terminal. The resource has a resource allocation period. When the base station determines that the currently allocated first competable resource has reached the resource allocation period, the terminal allocates a new first competable resource.

After the base station broadcasts the first competable resource in the current resource allocation period, the base station also broadcasts the acquired resource parameter threshold. When the terminal needs to send the uplink data to the base station, the terminal acquires the resource parameter threshold broadcasted by the base station, reads the first parameter in the resource parameter threshold, and learns, according to the first parameter, the maximum allowed for the current terminal to perform an unscheduled transmission. Resources. Optionally, the resource threshold parameter threshold may be a historical resource parameter threshold that is acquired by the base station, where the historical resource parameter threshold may be a resource parameter threshold in a previous resource allocation period, or may be a resource in a previous resource allocation period. The parameter threshold, that is, the historical resource parameter threshold may be a resource parameter threshold in any one of the resource allocation periods before the current resource allocation period, or may be an average value of the resource parameter thresholds in the previous multiple resource allocation periods, where the average value is The method may be an arithmetic mean value, and may also be a weighted average value. The manner in which the base station obtains the resource parameter threshold is not limited in the embodiment of the present invention. Generally, the base station selects a resource parameter threshold in a previous resource allocation period adjacent to the current resource allocation period as a resource threshold parameter threshold in the current resource allocation period.

S602: The base station receives the uplink data sent by the terminal, where the transmission mode of the uplink data sent by the terminal is determined by the terminal according to the value of the first parameter and the value of the second parameter, the second The parameter is a parameter used to characterize the actual resource occupied by the terminal for one unscheduled transmission.

The maximum resources corresponding to the values of the different first parameters are also different, and the actual resources corresponding to the values of the different second parameters are also different. After obtaining the first parameter and the second parameter, the terminal determines a transmission mode suitable for the terminal in the current scenario according to the value of the first parameter and the value of the second parameter, and uses the transmission mode to send uplink data to the base station. Optionally, the terminal may determine, according to the maximum resource corresponding to the value of the first parameter and the actual resource corresponding to the value of the second parameter, a transmission mode suitable for the terminal, and may also use a maximum resource corresponding to the value of the first parameter. The ratio of the actual resources corresponding to the value of the second parameter determines the transmission mode suitable for the terminal.

The method for uplink data transmission provided by the present invention, the base station broadcasts, to the terminal, a first parameter for characterizing the maximum resource allowed by the terminal to perform unscheduled transmission, so that the terminal can be used according to the value of the first parameter and used for characterization The value of the second parameter of the actual resource occupied by the terminal for the unscheduled transmission determines the transmission mode suitable for the terminal, and uses the transmission mode to send the uplink data to the base station, thereby taking into account the power consumption of the terminal and the probability of resource collision, thereby improving the The transmission efficiency of the terminal also saves the power consumption of the terminal.

Further, on the basis of the foregoing sixth embodiment, the first parameter includes: a maximum resource allowed by the terminal to perform unscheduled transmission, a maximum block length allowed by the terminal to perform unscheduled transmission, and the terminal Performing any one of the maximum allowed durations of the unscheduled transmission; the second parameter includes: an actual resource occupied by the terminal for performing an unscheduled transmission, and an actual block length of the terminal performing an unscheduled transmission The terminal performs any one of the actual times that the unscheduled transmission continues.

Specifically, in the LTE system, the foregoing first parameter includes a maximum resource allowed by the terminal to perform unscheduled transmission, a maximum block length allowed by the terminal to perform an unscheduled transmission, and a non-scheduled transmission by the terminal. The second parameter includes: the actual resource occupied by the terminal for one unscheduled transmission, the actual block length of the terminal performing the unscheduled transmission, and the actual time during which the terminal performs the unscheduled transmission. Any one of the above-mentioned "maximum resources allowed by the terminal to perform unscheduled transmission" refers to the maximum number of REs allowed by the terminal to perform unscheduled transmission, and the above "the actual resources occupied by the terminal for one unscheduled transmission" refers to The actual number of REs occupied by the terminal for a non-scheduled transmission.

In the UMTS system or the WCDMA system, the first parameter includes the terminal performing a non-scheduling The maximum time (or maximum number of slots) allowed for transmission, the second parameter includes the actual time (or the actual number of slots) that the terminal continues to perform an unscheduled transmission. In addition, in the UMTS system or the WCDMA system, the first parameter further includes a scrambling code set, where the scrambling code set includes N scrambling codes for the base station to descramble the uplink data sent by the terminal, where N is A preset value greater than or equal to 1.

Optionally, the foregoing uplink data may carry the identifier information of the terminal, where the identifier information may be used for the base station to distinguish which terminal the data is from, or may be used to indicate that the base station sends the downlink data corresponding to the uplink data to the terminal. The downlink data corresponding to the uplink data may be an ACK or a NACK. The identifier information may be the identifier information of the entire network level, and may also be the identifier information of the partial network level.

Specifically, the historical parameter threshold may be a resource parameter threshold in a previous resource allocation period of the base station, or may be a resource parameter threshold in any resource allocation period before the current resource allocation period, or may be artificial The set resource parameter threshold, or may be an average value of the first parameter in the historical resource parameter threshold in multiple resource allocation periods, where the average value may be an arithmetic mean value or a weighted average value. Generally, the base station selects a resource parameter threshold in the last adjacent resource allocation period of the base station, and correspondingly, the historical first parameter included in the historical parameter threshold threshold is used as the first parameter in the current resource allocation period by the base station. .

It should be noted that the base station in this embodiment has the function of recording the threshold value of the historical parameter. Therefore, the base station may use the historical first parameter in the historical parameter threshold threshold as the first parameter in the current resource allocation period.

FIG. 9 is a schematic flowchart diagram of Embodiment 8 of a method for uplink data transmission provided by the present invention. Real The embodiment relates to another specific process of the base station acquiring the first parameter of the resource parameter threshold before the base station broadcasts the resource parameter threshold. The base station in this embodiment does not have the function of recording a historical parameter threshold threshold. Before the above S601, the method includes:

S801: The base station acquires a historical unscheduled transmission feature in the coverage cell of the base station, where the historical unscheduled transmission feature includes: historical competable resource utilization, or a history of unscheduled transmission in the coverage cell of the base station The rate and the historical average time occupied by the base station to cover unscheduled transmissions within the cell.

Specifically, since the base station in this embodiment does not have the function of recording the threshold value of the historical parameter threshold, the base station needs the acquired historical unscheduled transmission feature in the coverage area of the base station to calculate the historical first parameter in the historical parameter threshold threshold. And taking the historical first parameter as the first parameter in the current resource allocation period. Optionally, the historical unscheduled transmission feature herein may be a historical unscheduled transmission feature in a previous neighboring resource allocation period of the base station, or may be a historical non-scheduled in any resource allocation period before the current resource allocation period. The transmission feature may also be an artificially set historical unscheduled transmission feature, or may be an average of historical unscheduled transmission characteristics in a plurality of previous resource allocation periods, where the average value may be an arithmetic mean value, or Is a weighted average. Generally, the base station selects a historical unscheduled transmission feature in a previous adjacent resource allocation period of the base station, where the historical unscheduled transmission feature includes: historical competable resource utilization, or the base station does not have a scheduling within the cell. The historical arrival rate of the transmission and the historical average time occupied by the unscheduled transmission within the coverage area of the base station.

S802: The base station determines, according to a maximum allowed resource collision probability, a preset mapping relationship, and the historical unscheduled transmission feature, a second parameter corresponding to the maximum allowed resource collision probability, and corresponding to the maximum allowed resource collision probability. The second parameter is determined as the first parameter; wherein the mapping relationship includes a correspondence between the maximum allowed resource collision probability and a parameter set; the parameter set includes: the historical unscheduled transmission feature, The second parameter corresponding to the maximum allowed resource collision probability and the historical competable resource allocated by the base station.

Specifically, after determining the historical unscheduled transmission feature, the base station determines, according to the preset mapping relationship and the maximum allowed resource collision probability, the second parameter corresponding to the maximum allowed resource collision probability, and uses the current parameter as the current resource allocation period. The first parameter inside. It should be noted that the size of the resource collision probability is determined by the competable resources allocated by the base station, the unscheduled transmission characteristics counted by the base station, and the second parameter of the terminal, and the mapping relationship is adopted by different competing resources. The source, the different unscheduled transmission characteristics, the second parameters of different terminals, and the different resource collision probabilities are obtained after certain testing, simulation or theoretical analysis, that is, the above mapping relationship includes different competable resources, The correspondence between different unscheduled transmission characteristics, different second parameters, and different resource collision probabilities. Therefore, the mapping relationship also includes a correspondence between a maximum allowed resource collision probability of the terminal and a parameter set, where the parameter set includes: the historical unscheduled transmission feature, the second parameter corresponding to the maximum allowed resource collision probability, and the base station allocation. The history of competing resources.

Since the historically competing resources are known, the historical unscheduled transmission feature is also known. Therefore, the base station can determine the second parameter corresponding to the maximum allowed resource collision probability according to the mapping relationship, and further the maximum allowed resource. The second parameter corresponding to the collision probability is determined as the first parameter.

The method for the uplink data transmission provided by the present invention obtains the first parameter in the resource parameter threshold by using the base station in different manners, and broadcasts the first parameter, so that the terminal can use the value of the first parameter and the terminal for characterizing the terminal. The value of the second parameter of the actual resource occupied by the unscheduled transmission is determined to be suitable for the transmission mode of the terminal, and the uplink data is sent to the base station by using the transmission mode, thereby taking into account the power consumption of the terminal and the probability of resource collision, thereby improving the terminal. The transmission efficiency also saves the power consumption of the terminal.

Optionally, after the base station broadcasts the first parameter, in order to ensure that the first parameter is more accurate, the base station may adjust the first parameter. Of course, the base station may not need to adjust.

The ninth embodiment shown in FIG. 10 below mainly relates to the adjustment process of the first parameter by the base station. The method of this embodiment is applicable to the adjustment of the first parameter in the LTE system and the GSM system. The method includes:

S901: The base station measures a current unscheduled transmission feature in the coverage cell of the base station; the current unscheduled transmission feature includes: a utilization rate of the first contentionable resource allocated by the base station, or the current coverage of the base station in the cell The arrival rate of the unscheduled transmission and the average time occupied by the current unscheduled transmission in the coverage cell of the base station, where the first competable resource is a competable resource allocated by the base station in the current resource allocation period.

Specifically, after the base station broadcasts the first parameter, in order to make the broadcasted first parameter more accurate, the base station measures the current unscheduled transmission feature in the coverage cell, that is, the base station can measure the first contention that the base station allocates. The utilization rate of the resource; or, the base station can also measure the arrival rate of the current unscheduled transmission in the coverage cell and the average time occupied by the current unscheduled transmission. It should be noted that the base station adjusts the first parameter after the first parameter is broadcast, because the base station acquires the first parameter and the second parameter only after the first parameter is broadcast, and according to the base station, The value of the first parameter and the value of the second parameter determine the current transmission mode suitable for the terminal, and then transmit the uplink data, so that the base station measures the utilization rate of the first competable resource, or the arrival rate of the unscheduled transmission and The average time taken by the current unscheduled transmission.

S902: The base station determines whether the resource collision probability corresponding to the current unscheduled transmission feature is greater than a maximum allowed resource collision probability; if yes, execute S903, if no, execute S904.

Specifically, after determining the current unscheduled transmission feature, the base station determines, according to the preset mapping relationship, the current second parameter of the terminal, and the current unscheduled transmission feature, the resource collision probability corresponding to the current unscheduled feature. It should be noted that the size of the resource collision probability is determined by the contentionable resource allocated by the base station, the unscheduled transmission feature counted by the base station, and the second parameter of the terminal. The mapping relationship is performed under different competable resources. Obtaining certain untested transmission characteristics, second parameters of different terminals, and different resource collision probabilities after certain testing, simulation or theoretical analysis, that is, the above mapping relationship includes different competable resources, different Correspondence between unscheduled transmission characteristics, different second parameters, and different resource collision probabilities.

Since the first competing resource allocated by the foregoing base station is known, the second parameter of the terminal is also known. Therefore, the base station can determine the resource collision probability corresponding to the current unscheduled transmission feature according to the mapping relationship. Thereafter, the base station determines the magnitude between the resource collision probability and the maximum allowed resource collision probability. It should be noted that the maximum allowed resource collision probability is determined by the communication system itself.

Optionally, in addition to the foregoing implementation manner of S902, the base station may further determine, according to the first competable resource, whether the current unscheduled transmission feature in the coverage cell of the base station is greater than the unscheduled transmission feature corresponding to the maximum allowed collision probability; If yes, execute S903, and if no, execute S904.

Optionally, in addition to the foregoing implementation manner of S902, the base station may further determine, according to the first competable resource, whether the current second parameter of the terminal is greater than a second parameter corresponding to the maximum allowed collision probability; if yes, executing S903, If not, execute S904.

S903: The base station adjusts the first parameter to obtain a new first parameter.

Specifically, after the base station determines that the resource collision probability corresponding to the current unscheduled transmission feature is greater than the maximum allowed resource collision probability, it indicates that the first parameter setting is unreasonable, and the first parameter needs to be adjusted. For example, assume that the current unscheduled transmission feature determined by the base station is the first competable resource The second parameter of the terminal is the number of REs actually occupied by the terminal in a non-scheduled transmission, and then the base station determines the resource collision probability corresponding to the first competable resource utilization according to the mapping relationship, and determines that the first competing If the resource collision probability corresponding to the resource utilization ratio is greater than the maximum allowed collision probability, the base station reduces the first parameter of the previous broadcast, so that some terminals in the coverage cell no longer perform unscheduled transmission, so that the first competable resource is utilized. The rate will decrease, so that the corresponding resource collision probability will also decrease, so the maximum allowed collision probability will not be exceeded.

S904: The base station does not adjust the first parameter.

The method for the uplink data transmission provided by the present invention, the base station adjusts the acquired first parameter, so that the first parameter is closer to the current usage scenario, and then the terminal has a non-scheduled transmission in the current scenario, and the resource collision probability Less than the maximum allowed resource collision probability further improves the efficiency of the terminal's unscheduled transmission.

FIG. 11 is a schematic flowchart diagram of Embodiment 10 of a method for uplink data transmission according to the present invention. The method of this embodiment is applicable to the adjustment of the first parameter in the UMTS system. On the basis of the foregoing embodiment shown in FIG. 9, the resource parameter threshold further includes a scrambling code set, where the scrambling code set includes N scrambling codes used by the base station to descramble the uplink data sent by the terminal. N is a preset value greater than or equal to 1. Therefore, the historical unscheduled transmission feature in the foregoing embodiment 8 further includes: a scrambling code utilization rate per unit time and/or a received total wideband power (RTWP). Further, after the foregoing S802, the method further includes:

S1001: The base station adjusts the first parameter according to a historical scrambling code utilization rate and/or the historical RTWP in the scrambling code set in the unit time.

Optionally, the base station may adjust the first parameter according to the historical scrambling code utilization rate and/or the historical RTWP in the unit time, in addition to adjusting the first parameter according to the historical scrambling code utilization rate and/or the historical RTWP in the unit time. Code collection. Data is scrambled and descrambled due to uplink and downlink data transmission in the UMTS system. For the above data transmission, it is assumed that the terminal uses the scrambling code A to scramble the uplink data and then sends the data to the base station, and the base station needs to try to use one of the large number of scrambling codes to descramble the scrambling code one by one; however, in this embodiment Since the terminal can select a scrambling code from the set of scrambling codes, the base station can select a scrambling code in the scrambling code set to perform a descrambling attempt, which reduces the complexity of the base station. The base station can adjust the scrambling code set according to the historical scrambling code utilization rate and/or the historical RTWP in the unit time to further optimize the scrambling code set, and further reduce the complexity of the base station.

The method for uplink data transmission provided by the present invention, the first parameter is adjusted by the base station according to the historical scrambling code utilization rate and/or the historical RTWP in a unit time, so that the first parameter is closer to the current usage scenario, and the terminal is in the current scenario. When the unscheduled transmission is performed, the resource collision probability is less than the maximum allowed resource collision probability, which further improves the efficiency of the unscheduled transmission of the terminal; on the other hand, the base station adjusts the interference according to the historical scrambling code utilization rate and/or the historical RTWP per unit time. The code set further reduces the complexity of the base station.

Embodiment 11 of the present invention provides a method for uplink data transmission. The method in this embodiment involves the base station transmitting the weighting coefficient in the resource parameter threshold to the terminal in the coverage cell, so that the terminal can quickly determine the specific transmission mode suitable for the terminal when the unscheduled transmission fails. process. On the basis of any of the foregoing embodiments, in the embodiment, the resource parameter threshold further includes a weighting coefficient, where the weighting coefficient is used to indicate that the terminal determines that the transmission mode is a non-scheduled transmission mode, and When the uplink data fails to be transmitted by the unscheduled transmission mode, the transmission mode is re-determined according to the product of the value of the second parameter and the weighting coefficient and the value of the first parameter.

It should be noted that, in this embodiment, the scenario in the foregoing Embodiment 2 is applicable, that is, the scenario in which the content included in the first parameter and the second parameter belongs to the same type of content in terms of attributes. In this embodiment, the first parameter has a certain correspondence relationship with the second parameter, that is, when the first parameter is the maximum resource allowed by the terminal to perform unscheduled transmission, and the second parameter is occupied by the terminal performing a non-scheduled transmission. Actual resource; or, when the first parameter is the maximum block length allowed by the terminal for unscheduled transmission, the second parameter is the actual block length of the terminal for unscheduled transmission; or, when the first parameter is for the terminal once The maximum time allowed for scheduling transmissions, and the second parameter is the actual time that the terminal continues to perform an unscheduled transmission. The above weighting coefficients may be some type of random numbers distributed within a certain range. Optionally, the weighting coefficient may be a random number distributed between 0 and 1, may be a random number distributed between 1, 2, and may also be a random number distributed between 0.9 and 1.3.

Specifically, the base station broadcasts the resource parameter threshold to the terminal, where the resource parameter threshold includes the first parameter and the weighting coefficient. Of course, the resource parameter threshold may further include a scrambling code set. In this embodiment, the resource parameter threshold includes the first A parameter and a weighting factor are taken as examples. Assuming that the resource parameter threshold of the broadcast has been adjusted, the terminal determines the value of the first parameter and the value of the second parameter. Suitable for the transmission mode of the terminal. When the terminal determines that the current transmission mode suitable for the terminal is unscheduled transmission, and the terminal fails to transmit the uplink data by using the determined unscheduled transmission mode (for example, a collision occurs), the terminal re-determines a new one according to the weighting coefficient configured by the base station. The value of the second parameter, that is, the terminal multiplies the value of the second parameter by the weighting coefficient, and then determines whether the product is smaller than the value of the first parameter. The purpose of this is to change the value of the second parameter according to a certain distribution law, so that the terminal can quickly determine the transmission mode suitable for itself. It should be noted that, what kind of random number is used for the weighting coefficient, the base station and the terminal may agree in advance, or the base station's weighting coefficient generation method may be broadcasted while the base station broadcasts the resource parameter threshold.

When the terminal determines that the product of the value of the second parameter and the weighting coefficient is greater than the value of the first parameter, the terminal performs scheduling transmission; when the terminal determines that the product of the value of the second parameter and the weighting coefficient is smaller than the first parameter The value continues, the terminal continues to determine that the transmission mode of the terminal is a non-scheduled transmission mode, and then the terminal transmits the uplink data again by using the unscheduled transmission mode, and determines whether the current unscheduled transmission fails; if successful, the current non-scheduled one. The transmission ends. If the failure occurs, the terminal may obtain a new weighting coefficient according to a preset rule. Optionally, the preset rule may gradually double the weighting coefficient as the number of unscheduled transmission failures increases. After that, the terminal multiplies the new weighting coefficient and the value of the second parameter again to obtain a new product, and then determines whether the new product is greater than the value of the first parameter, and so on, until the judgment result is greater than the transmission of the terminal. The mode is to schedule the transmission.

In the uplink data transmission method provided by the embodiment of the present invention, the base station sets the weighting coefficient in the resource parameter threshold, so that the terminal can switch to the scheduled transmission in time after determining that the unscheduled transmission fails, thereby further improving the uplink data transmission efficiency of the terminal. .
